Abstract:

Demonstrations are presented to show that the perception of structure in Marroquin patterns is disrupted if the dots comprising the pattern have opposite contrast polarity, and also if the dots comprising the pattern are separated in stereoscopic depth. It is also demonstrated that the perception of structure in a Marroquin pattern is made possible if the pattern is separated in stereoscopic depth from ‘noise’ dots, where the pattern structure cannot be perceived in either half of the unfused stereogram. In these respects the perception of Marroquin patterns is similar to the perception of Glass patterns. These findings are thus consistent with the proposal that the perception both of Marroquin and of Glass patterns is based on the construction of virtual lines.

Abstract:

To gain insight into the internal representation of temporal patterns, we studied the perception and reproduction of tone sequences in which only the tone-onset intervals were varied. A theory of the processing of such sequences, partly implemented as a computer program, is presented. A basic assumption of the theory is that perceivers try to generate an internal clock while listening to a temporal pattern. This internal clock is of a flexible nature that adapts itself to certain characteristics of the pattern under consideration. The distribution of accented events perceived in the sequence is supposed to determine whether a clock can (and which clock will) be generated internally. Further it is assumed that if a clock is induced in the perceiver, it will be used as a measuring device to specify the temporal structure of the pattern. The nature of this specification is formalized in a tentative coding model. Three experiments are reported that test different aspects of the model. In Experiment 1, subjects reproduced various temporal patterns that only differed structurally in order to test the hypothesis that patterns more readily inducing an internal clock will give rise to more accurate percepts. In Experiment 2, clock induction is manipulated experimentally to test the clock notion more directly. Experiment 3 tests the coding portion of the model by correlating theoretical complexity of temporal patterns based on the coding model with complexity judgments. The experiments yield data that support the theoretical ideas.

Abstract:

Humans have a tendency to perceive inanimate objects as animate based on simple motion cues. Although animacy is considered as a complex cognitive property, this recognition seems to be spontaneous. Researchers have found that young human infants discriminate between dependent and independent movement patterns. However, quick visual perception of animate entities may be crucial to non-human species as well. Based on general mammalian homology, dogs may possess similar skills to humans. Here, we investigated whether dogs and humans discriminate similarly between dependent and independent motion patterns performed by geometric shapes. We projected a side-by-side video display of the two patterns and measured looking times towards each side, in two trials. We found that in Trial 1, both dogs and humans were equally interested in the two patterns, but in Trial 2 of both species, looking times towards the dependent pattern decreased, whereas they increased towards the independent pattern. We argue that dogs and humans spontaneously recognized the specific pattern and habituated to it rapidly, but continued to show interest in the ‘puzzling’ pattern. This suggests that both species tend to recognize inanimate agents as animate relying solely on their motions.

Abstract:

Due to the increase of electric motor cars for preventing spread of carbon dioxide, noise atmosphere inside the car compartment is more important for the perception of tire-pavement noise. This paper describes the impression of pattern noise created by the tire thread pattern under real running condition. Our impression on tire-pattern noise is more prominent if the peak level of the pattern noise together with its frequency location and width of the peak. This paper deals with our impression on tire pattern noise how our impression vary with its peak level and frequency location.

Abstract:

AbstractPrevious research has demonstrated a link between illusory pattern perception and various irrational beliefs. On this basis, we hypothesized that participants who displayed greater degrees of illusory pattern perception would also be more likely to rate pseudo-profound bullshit statements as profound. We find support for this prediction across three experiments (N = 627) and four distinct measures of pattern perception. We further demonstrate that this observed relation is restricted to illusory pattern perception, with participants displaying greater endorsement of non-illusory patterns being no more likely to rate pseudo-profound bullshit statements as profound. Additionally, this relation is not a product of a general proclivity to rate all statements as profound and is not accounted for by individual differences in analytic thinking. Overall, we demonstrate that individuals with a tendency to go beyond the available data such that they uncritically endorse patterns where no patterns exist are also more likely to create and endorse false-meaning in meaningless pseudo-profound statements. These findings are discussed in the context of a proposed framework that views individuals’ receptivity to pseudo-profound bullshit as, in part, an unfortunate consequence of an otherwise adaptive process: that of pattern perception.

Abstract:

Abstract Background. Transcutaneous electrical nerve stimulation (TENS) is generally applied for tactile feedback in the field of prosthetics. The distinct mechanisms of evoked tactile perception between stimulus patterns in conventional TENS (cTENS) and neuromorphic TENS (nTENS) are relatively unknown. This is the first study to investigate the neurobiological effect of nTENS for cortical functional mechanism in evoked tactile perception. Methods. Twenty-one healthy participants were recruited in this study. Electroencephalogram (EEG) was recorded while the participants underwent a tactile discrimination task. One cTENS pattern (square pattern) and two nTENS patterns (electromyography and single motor unit patterns) were applied to evoke tactile perception in four fingers, including the right and left index and little fingers. EEG was preprocessed and somatosensory-evoked potentials (SEPs) were determined. Then, source-level functional networks based on graph theory were evaluated, including clustering coefficient, path length, global efficiency, and local efficiency in six frequency bands. Main results. Behavioral results suggested that the single motor units (SMUs) pattern of nTENS was the most natural tactile perception. SEPs results revealed that SMU pattern exhibited significant shorter latency in P1 and N1 components than the other patterns, while nTENS patterns have significantly longer latency in P3 component than cTENS pattern. Cortical functional networks showed that the SMU pattern had the lowest short path and highest efficiency in beta and gamma bands. Conclusion. This study highlighted that distinct TENS patterns could affect brain activities. The new characteristics in tactile manifestation of nTENS would provide insights for the application of tactile perception restoration.

Abstract:

Taste perception is a primary driver of food choices; however, little is known about how perception of all five tastes (sweet, salt, sour, bitter, umami) collectively inform dietary patterns. Our aim was to examine the associations between a multivariable measure of taste perception—taste perception profiles—and empirically derived dietary patterns. The cohort included 367 community-dwelling adults (55–75 years; 55% female; BMI = 32.2 ± 3.6 kg/m2) with metabolic syndrome from PREDIMED-Plus, Valencia. Six taste perception profiles were previously derived via data-driven clustering (Low All, High Bitter, High Umami, Low Bitter and Umami, High All But Bitter, High All But Umami); three dietary patterns were derived via principal component analysis (% variance explained = 20.2). Cross-sectional associations between profiles and tertials of dietary pattern adherence were examined by multinomial logistic regression. Overall, there were several significant differences in dietary pattern adherence between profiles: the vegetables, fruits, and whole grains pattern was significantly more common for the High All But Umami profile (OR range for high vs. low adherence relative to other profiles (1.45–1.99; 95% CI minimum lower, maximum upper bounds: 1.05, 2.74), the non-extra virgin olive oils, sweets, and refined grains pattern tended to be less common for Low All or High Bitter profiles (OR range: 0.54–0.82), while the alcohol, salty foods, and animal fats pattern tended to be less common for Low Bitter and Umami and more common for High All But Bitter profiles (OR range: 0.55–0.75 and 1.11–1.81, respectively). In conclusion, among older adults with metabolic syndrome, taste perception profiles were differentially associated with dietary patterns, suggesting the benefit of integrating taste perception into personalized nutrition guidance.

Abstract:

The objective of this research is to present the base data for development of teawares with Sotdae-patterns by studying the emotion and perception of expert group and consumer group. For this study, teawares with individually drawn five types of Sotdae-pattern were made in October 1-31, 2022. These teawares were photographed and each pattern was included in the survey. A total of 24 experts and 26 consumers were surveyed, who use teawares more than once a week. The survey was conducted in November 1-7, 2022. and the survey data were analyzed by SPSS 29.0. The main results are as follows. First, the five Sotdae-patterns were generally highly evaluated with Korean emotion. In addition, patterns of Bukhansan mountain-Sotdae and Ojuk(black bamboo)-Sotdae showed natural and artistic sensibility, whereas, patterns of Sky-Sotdae, Earth-Sotdae and Community-Sotdae were assessed with inventive and individual emotion. Second, the purchase intention of teawares was high in the order of Ojuk-Sotdae pattern > Bukhansan mountain-Sotdae pattern > Sky-Sotdae pattern > Community-Sotdae pattern > Earth-Sotdae pattern. Third, using the Sotdae-pattern teawares reflected introspection with psychological stability and relaxed mind, and expectation of communication in a comfortable mood with someone while drinking tea.

Abstract:

The texture of an object’s surface influences its perceived spatial extent. For example, Hermann von Helmholtz reported that a square patch with black and white stripes appears elongated perpendicular to the stripes’ orientation. This time-honoured finding stands in contrast with more recent recommendations by interior-design experts who suggest that stripe wall patterns make rooms appear elongated in the direction parallel to the stripes’ orientation. In a series of four experiments, we presented stripe wall patterns and varied the orientation of the stripes (horizontal vs. vertical) and their density (number of stripes per degree of visual angle). Subjects estimated the width and height of stereoscopically presented interior spaces. Stripe patterns with higher densities made rooms appear both wider and higher than did stripe patterns with lower densities or plain walls. In contrast to both the predictions from the Helmholtz-square and the design guidelines, this effect was only weakly modulated by pattern orientation, in the sense that rooms appeared elongated in the direction parallel to the stripes’ orientation. We conclude that object-based texture effects cannot be generalised to interior space perception. For a room’s perceived spatial extent, pattern density is more important than pattern orientation.

Abstract:

Abstract Whether subtle differences in the emotional context during threat perception can be detected by multi-voxel pattern analysis (MVPA) remains a topic of debate. To investigate this question, we compared the ability of pattern recognition analysis to discriminate between patterns of brain activity to a threatening versus a physically paired neutral stimulus in two different emotional contexts (the stimulus being directed towards or away from the viewer). The directionality of the stimuli is known to be an important factor in activating different defensive responses. Using multiple kernel learning (MKL) classification models, we accurately discriminated patterns of brain activation to threat versus neutral stimuli in the directed towards context but not during the directed away context. Furthermore, we investigated whether it was possible to decode an individual’s subjective threat perception from patterns of whole-brain activity to threatening stimuli in the different emotional contexts using MKL regression models. Interestingly, we were able to accurately predict the subjective threat perception index from the pattern of brain activation to threat only during the directed away context. These results show that subtle differences in the emotional context during threat perception can be detected by MVPA. In the directed towards context, the threat perception was more intense, potentially producing more homogeneous patterns of brain activation across individuals. In the directed away context, the threat perception was relatively less intense and more variable across individuals, enabling the regression model to successfully capture the individual differences and predict the subjective threat perception.

Full text

Abstract:

The effects of variations in three pairs of variables on identification and discrimination of rhythmic patterns in pure-tone sequences were investigated. It was found that adding a timing difference to two sequences that differed in terms of the pattern of tone intensities improved discrimination if variations of the two variables converged on the same rhythmic pattern but did not help if the variation in timing undermined the rhythmic pattern created by the intensity variation. Adding a difference in the intensities of tones to two sequences that differed in terms of the pitch structure produced a similar pattern of results. The effect of adding a difference in pitch structure to two sequences that differed in terms of timing was not reliably related to the way the differences were combined. The results showed that, at least for some variables, predicting discrimination performance from probabilities of detecting a rhythmic pattern is possible. The relationship of the results to cue trading in speech perception and research possibilities with similar methods are discussed.

Abstract:

When we have a rich and vivid memory for a past experience, it often feels like we are transported back in time to witness once again this event. Indeed, a perfect memory would exactly mimic the experiential quality of direct sensory perception. We used fMRI and multivoxel pattern analysis to map and quantify the similarity between patterns of activation evoked by direct perception of a diverse set of short video clips and the vivid remembering, with closed eyes, of these clips. We found that the patterns of distributed brain activation during vivid memory mimicked the patterns evoked during sensory perception. Using whole-brain patterns of activation evoked by perception of the videos, we were able to accurately classify brain patterns that were elicited when participants tried to vividly recall those same videos. A discriminant analysis of the activation patterns associated with each video revealed a high degree (explaining over 80% of the variance) of shared representational similarity between perception and memory. These results show that complex, multifeatured memory involves a partial reinstatement of the whole pattern of brain activity that is evoked during initial perception of the stimulus.

Abstract:

The Indonesian government have implemented agricultural production cost insurance since 2015 called Asuransi Usaha Tani Padi (AUTP). It is an issue that the rate of farmer participation in the insurance is still low. As a challenge to increase participation, it becomes important to be aware of motivation, behavior, and perception that influence the practical risk management of farmers. This study investigated the relationship between cropping pattern diversification (as risk management) and factors such as motivation, behavior, and perception. Based on a field survey of 240 smallholder farmers in Garut District, West Java Province, these were the characteristics of farmers who practiced cropping pattern diversification: (1) high-risk perception (impact and probability); (2) risk-averse; and (3) economic motivation. The study revealed that approximately one-third of farmers had risk-neutral and low-risk perceptions of whom approximately 70.7 percent practiced single cropping patterns. They may not adopt any risk- coping strategies unless they are aware of the risks that they face. Improving awareness about the negative impacts of risks on income from farming might encourage them to adopt risk-coping strategies for both on-farm risk coping (such as cropping pattern diversification) and off-farm risk-coping (such as agricultural insurance).

Abstract:

Formal language theory has been extended to two-dimensional patterns, but little is known about two-dimensional pattern perception. We first examined spontaneous two-dimensional visual pattern production by humans, gathered using a novel touch screen approach. Both spontaneous creative production and subsequent aesthetic ratings show that humans prefer ordered, symmetrical patterns over random patterns. We then further explored pattern-parsing abilities in different human groups, and compared them with pigeons. We generated visual plane patterns based on rules varying in complexity. All human groups tested, including children and individuals diagnosed with autism spectrum disorder (ASD), were able to detect violations of all production rules tested. Our ASD participants detected pattern violations with the same speed and accuracy as matched controls. Children's ability to detect violations of a relatively complex rotational rule correlated with age, whereas their ability to detect violations of a simple translational rule did not. By contrast, even with extensive training, pigeons were unable to detect orientation-based structural violations, suggesting that, unlike humans, they did not learn the underlying structural rules. Visual two-dimensional patterns offer a promising new formally-grounded way to investigate pattern production and perception in general, widely applicable across species and age groups.

Full text

Abstract:

The perceived contrast of a pulsed grating of about 100 ms duration can exceed that of shorter or longer exposures. We investigated this contrast enhancement effect with pattern masking. The pulsed mask patterns were extended cosines (5 deg square, 35 cd m−2 mean luminance, 0.3 contrast) of 50 to 500 ms duration. Mask spatial frequency was 1 or 6 cycles deg−1. The test patterns (of equivalent spatial frequency) were sixth derivative Gaussians, either positive (ON pathway mediation) or negative (OFF pathway mediation) and of 30 ms duration. The test pattern could be centred on a light bar of the cosine (positive contrast) or a dark bar (negative contrast). Test and mask had simultaneous onset. For a 1 cycle deg−1 test and mask of the same polarity, the test threshold/mask duration function is nonmonotonic (peak at 83 – 100 ms). The function was similar for either positive or negative stimuli. Thus, we measured an analogue to the contrast enhancement effect, and found enhancement for negative as well as positive contrast components. For same-polarity 6 cycles deg−1 test and mask, threshold increased monotonically to 500 ms (no enhancement). For both 1 and 6 cycles deg−1 stimuli of opposite polarity, the threshold/mask duration function is sharply elevated and constant for masks of 83 ms or more. The same-polarity masking functions imply activation of either transient (1 cycle deg−1 stimuli) or sustained (6 cycles deg−1 stimuli) ON or OFF pathways. The opposite-polarity functions suggest that the time course of ON — OFF pathway interaction is similar for sustained and transient pathways.

When we regard the mixed state of patterns as a part of each pattern, the durations of the retrieved pattern obey unimodal distributions. We confirmed that no chaotic properties are observed in the time series of durations, consistent with the findings of previous psychological studies. Moreover, it is shown that our model also reproduces two properties of multistable perception that characterize the relationship between the contrast of inputs and the durations.

Abstract:

Recent findings suggest that the visual system is biased by its past stimulation to detect one direction of motion over others. Three experiments were designed to investigate whether this bias is mediated by the direction or by the velocity of the past stimulation, and whether this bias is offset by contradictory pattern or depth information. Observers were presented with two solid or random-dot patterns that moved across a display screen in antiphase. As the two patterns reached the center of the screen, they became superimposed in such a way that their subsequent directions were ambiguous. Results from experiment 1 showed that the probability of perceiving these patterns as continuing to move in the same directions was significantly greater when they moved at a constant velocity than when they moved at a variable velocity. Results from experiments 2 and 3 revealed that this directional bias was reversed only gradually as an increasing amount of contradictory pattern information was introduced, but that this reversal was quite abrupt when a relatively small amount of contradictory depth information was introduced. Collectively, these results suggest that a directional bias in the perception of moving patterns is mediated not only by the direction of the previous stimulation, but also by the velocity of that stimulation. Moreover, the analyses of pattern and motion information appear relatively independent during the early stages of visual processing, but the analyses of depth and motion information appear considerably more interdependent.

Abstract:

The encoding of positional relationships between pattern elements in eccentric vision was studied with different patterns consisting of the same short line segments in different positions. In each trial two stimulus patterns were flashed one above the other and the subject had to decide whether the patterns were identical or mirror symmetric (experiment 1) or whether the patterns were the same or different (experiments 2 and 3). The ability to discriminate between identical and mirror symmetric patterns was reduced in eccentric vision, even when the patterns were size-scaled according to the cortical magnification factor and thus the patterns were similarly visible at the different eccentricities. The results agree with the notion that eccentric vision is inferior to central vision in tasks which require proper encoding of information about the relative positions of pattern elements.

Abstract:

Background: Parental bonding perception leads to different domains in future life. The goal of this study was to investigate the role of parental bonding perception in predicting the communication patterns of couples in Tehran. Methods: This correlational and descriptive study was done on 338 individuals in Tehran, Iran who voluntarily participated in the research in 2016. Communication Pattern Questionnaire (CPQ) and Parental Bonding Instrument (PBI) were used to collect data. Pearson correlation method and multiple regression were used for data analysis using the SPSS v. 22 software. Results: Data revealed that in the husband group, father care was the only predictor of higher scores of the mutual constructive communication pattern. In the group of wives, father indifference was the predictor of lower scores of constructive communication pattern and mother encouragement of dependency was the predictor of the higher scores of the constructive communication pattern. Mother encouragement of autonomy was the only predictor of lower scores of husband demand/ wife withdraws but no variable predicted wife demand/ husband withdraw pattern. In addition, fathers’ encouragement of autonomy in husbands was predictive of spouses’ constructive communication patterns. Also, fathers’ encouragement of autonomy in husbands was predictive of spouses’ constructive communication patterns. Conclusion: The association between parental bonding perception and couple’s communication patterns highlight the importance of early years of childhood and parent-child relationship in future life.

Abstract:

We examined (i) perceived slant of a textured surface about a vertical axis as a function of disparity magnitude for horizontal-size disparity, vertical-size disparity, and overall-size disparity; and (ii) interactions between patterns with various types and magnitudes of size disparity and superimposed or adjacent zero-disparity stimuli. Horizontal-size disparity produced slant which increased with increasing disparity, was enhanced by superimposed zero-disparity stimuli, and induced contrasting slant in superimposed or adjacent zero-disparity stimuli. Vertical-size disparity produced opposite slant (induced effect) which was reduced to near zero by a superimposed zero-disparity pattern and both patterns appeared as one surface. Adjacent vertical-size-disparity and zero-disparity patterns appeared as separate surfaces with a wide curved boundary. Overall-size disparity produced slant which was enhanced by a superimposed zero-disparity pattern and less so by a zero-disparity line, and induced more slant in a zero-disparity line than in a zero-disparity pattern. The results are discussed in terms of depth underestimation of isolated surfaces, depth enhancement, depth contrast, and the processing of deformation disparity.

Abstract:

Neurometric analysis has proven to be a powerful tool for studying links between neural activity and perception, especially in visual and somatosensory cortices, but conventional neurometrics are based on a simplistic rate-coding hypothesis that is clearly at odds with the rich and complex temporal spiking patterns evoked by many natural stimuli. In this study, we investigated the possible relationships between temporal spike pattern codes in the primary auditory cortex (A1) and the perceptual detection of subtle changes in the temporal structure of a natural sound. Using a two-alternative forced-choice oddity task, we measured the ability of human listeners to detect local time reversals in a marmoset twitter call. We also recorded responses of neurons in A1 of anesthetized and awake ferrets to these stimuli, and analyzed these responses using a novel neurometric approach that is sensitive to temporal discharge patterns. We found that although spike count-based neurometrics were inadequate to account for behavioral performance on this auditory task, neurometrics based on the temporal discharge patterns of populations of A1 units closely matched the psychometric performance curve, but only if the spiking patterns were resolved at temporal resolutions of 20 msec or better. These results demonstrate that neurometric discrimination curves can be calculated for temporal spiking patterns, and they suggest that such an extension of previous spike count-based approaches is likely to be essential for understanding the neural correlates of the perception of stimuli with a complex temporal structure.

Abstract:

AbstractWe studied the development of sensitivity to complex motion using plaid patterns. We hypothesized, based on neurophysiological data showing a dearth of pattern direction–selective (PDS) cells in area medial temporal (MT) of infant macaques, that sensitivity to pattern motion would develop later than other forms of global motion sensitivity. We tested 10 macaque monkeys (Macaca nemestrina) ranging in age from 7 weeks to 109–160 weeks (adult). The monkeys discriminated horizontal from vertical pattern motion; sensitivity for one-dimensional (1D) direction discrimination and detection were tested as control tasks. The results show that pattern motion discrimination ability develops relatively late, between 10 and 18 weeks, while performance on the 1D control tasks was excellent at the earliest test ages. Plaid discrimination performance depends on both the speed and spatial scale of the underlying patterns. However, development is not limited by contrast sensitivity. These results support the idea that pattern motion perception depends on a different mechanism than other forms of global motion perception and are consistent with the idea that the representation of PDS neurons in MT may limit the development of complex motion perception.

Abstract:

The glare illusion is an illusory perception of brightness enhancement and self-luminosity from a glare pattern, which consists of a central white area and surrounding areas with radial darkening luminance gradients. Here, we report a phenomenon we call “the switching glare illusion.” In this phenomenon, observers experience perceptual alternation in which the glare effect repeatedly appears and disappears or attenuates when the multiple glare patterns are arranged in a grid pattern. This perceptual alternation is caused by a figure-ground reversal in the grid pattern. Since such a phenomenon has not been reported for a single glare pattern, this is caused by arranging multiple glare patterns in a grid. This new finding is worthy for further studies for understanding the mechanisms underlying the glare effect and brightness perception.

Abstract:

This article aims to describe the results of research on interaction patterns and characteristics of classroom interaction in teaching and learning activities in English class in Bukittinggi West Sumatera, as well as perceptions of students and teachers to the interaction. This research type is descriptive and research data is classroom discourse between teacher and student when studying English, as well as questionnaire of student and teacher to class interaction. Participants are 4 English teachers with 3 meetings for each teacher (12 meetings). The research used classification theory of class interaction type from Lindgren (1981), Wajnryb (1992), and El-Hanafi (2013), while for interaction characteristics used Flanders' Interaction Analysis Code (FIAC) model. The results of this study indicate that the dominant interaction pattern is teacher-student with one way traffic interaction, while the dominant interaction characteristic is the cross content. From teacher perception, dominant interaction pattern is student-student interaction and dominant interaction characteristic is teacher support. Whereas from student perception, dominant interaction pattern is teacher-student with two-way traffic interaction, and characteristic of dominant interaction is content cross. It can be concluded that the interaction pattern and the interaction characteristics that occur in the teaching and learning process are strongly influenced by the material and skills taught by the teacher

Abstract:

Background: The human voice is a prominent feature and the most susceptible to environmental changes, lifestyle, and age. Voice problems tend to be significantly under-reported and consequently less likely to be clinically treated. It is yet to be established if the cause lies in the lack of awareness or the impermanent nature of most voice disorders. Objective: To evaluate the patterns and perceptions about vocal use and misuse among young adults in Pakistan. Method: The study used a cross-sectional survey design. A convenient sampling technique was employed to collect the data from n=242 healthy young adults aged 18-25 years studying in colleges and universities of Rawalpindi and Islamabad. A 32-item survey questionnaire titled “patterns and Perceptions about voice use and Misuse” was employed, with a portion for demographic data and five sections dedicated to general awareness, self-perception about voice, and habits of vocal use and misuse. Results: The results regarding the perception and patterns of vocal use and misuse reflects that 88.3% of the participants agreed that precautionary measure would help them to avoid voice disorder. In contrast, 83.3% of the participants reported screaming and yelling as part of their vocal pattern. Participants showed a strong association with the positive attributes related to their voice such as beautiful as 82.2% of the participants reported their voice as pleasant. Conclusion: The study concluded that the outcome of participants’ perceptions and their patterns of vocal behavior were significantly atypical. Screaming and smoking were the most frequently reported response by adults but on the other hand, they did not seek professional help and did not perceive their voice as unpleasant voice.

Full text

Abstract:

A study is reported of (i) the perceived inclination of a textured surface in depth about a horizontal axis as a function of disparity magnitude for horizontal-shear disparity, vertical-shear disparity, and rotation disparity; and (ii) interactions between patterns with shear or rotation disparity and superimposed or adjacent patterns or lines with zero disparity. Horizontal-shear disparity produced strong inclination which was enhanced by superimposed or adjacent zero-disparity stimuli. It produced little or no inclination contrast in superimposed or adjacent zero-disparity stimuli. Vertical-shear disparity produced inclination in the opposite direction (induced effect) which was reduced to near zero by a superimposed zero-disparity pattern. Adjacent vertical-shear and zero-disparity patterns appeared inclined at slightly different angles with a wide curved boundary. This suggests that vertical-shear disparities are averaged over a wide area. Rotation disparity produced minimal inclination. A superimposed or adjacent zero-disparity line appeared strongly inclined. A superimposed or adjacent zero-disparity pattern appeared vertical and caused the pattern with rotation disparity to appear inclined. Four mechanisms are proposed to account for the results: depth contrast, depth enhancement, deformation-disparity processing, and disparity transfer arising from cyclovergence.

Abstract:

The current trend in display technology is towards achieving larger color gamut and higher brightness levels. However, it should be noted that visual perception of brightness intensity may differ from physical brightness intensity. The HelmholtzKohlrausch effect(H‐K effect) refers to the phenomenon where the perceived brightness of a color increases as its purity or saturation increases while keeping its luminance constant. In order to investigate the relationship between visual perception brightness and lightness, hue and color purity, an experiment was conducted using an RGB laser television as the display device. A total of 12 subjects participated in the visual perception brightness experiment. Based on the experimental results, the visual perceptual brightness for different color patterns was determined. Subsequently, a multilayer perceptron neural network was employed to depict the variation pattern of visual perception of brightness within the CIELAB color space. Finally, Fairchild's H‐K effect compensation formula was revised using nonlinear least squares method based on these experimental findings.

Abstract:

Personality disorders are rooted in maladaptive interpersonal behaviors. Previously, researchers have assessed interpersonal behaviors using self-ratings of one's own behaviors and third-person ratings of dyadic interactions. Few studies have examined individuals' perceptions of others' interpersonal behaviors. Using a sample of 470 undergraduate students, the authors examined patterns of interpersonal perception as well as influences of these patterns on psychological functioning. Findings showed that people tend to like interpersonal behaviors that are similar to their own and become bothered by behaviors that are the opposite of their own. Such a pattern is particularly characteristic on the warmth dimension and is consistent across different levels of closeness of the relationship. The authors also found small but significant effects of interpersonal perception on personality and general psychological functioning, above and beyond effects of individuals' own interpersonal traits. Such findings highlight the importance of including perceptions of others in investigating interpersonal dynamics when understanding personality disorders.
