Résumé :

The cueing model for sensor cueing phased array radar is built in this paper to research the mutual cueing of multi-sensor in multi-platform for target searching. For the purpose of establishing the distribution probability density model of targets in cueing airspace, cueing error of multi-platform is derived with error transfer method. The successful cueing probability and false hand-off probability between platforms are analyzed, meanwhile the requirement of timeliness is defined. An optimized target searching strategy of cueing radar which adopts distance search through using the cueing center as starting point and controlling false hand-off probability of a single wave position is put forward. The simulation result illustrates that the searching strategy can significantly save radar search resources to capture target successfully, simultaneously decrease the false hand-off probability. The strategy can be applied to the design of dynamic programming software of multi-sensor in multi-platform for collaborative search, which requires accuracy and real-time capability.

Résumé :

In order to build the sensor network facing the task of multisensor crossing cueing, the requirements of initiating cueing and being cued are analyzed. Probability theory is used when building models, then probability of sensor cueing in the case of target moving is given, and, after that, the best distance between two sensors is calculated. The operational environment is described by normal distribution function. In the process of distributing sensor network, their elements, operational environment demand of cueing, and the probability of sensor network coverage are considered; then the optimization algorithm of sensor network based on hypothesis testing theory is made. The simulation result indicates that the algorithm can make sensor network which is required. On the basis of that, the two cases, including targets that make linear motion and orbit motion, are used to test the performance of the sensor network, which show that the sensor network can make uninterrupted detection on targets through multisensor cross cuing.

Résumé :

Existing research has found that spatial attention alters how various stimulus properties are perceived (e.g., luminance, saturation), but few have explored whether it improves the accuracy of perception. To address this question, we performed two experiments using modified Posner cueing tasks, wherein participants made speeded detection responses to peripheral colour targets and then indicated their perceived colours on a colour wheel. In E1, cues were central and endogenous (i.e., prompted voluntary attention) and the interval between cues and targets (stimulus onset asynchrony, or SOA) was always 800 ms. In E2, cues were peripheral and exogenous (i.e., captured attention involuntarily) and the SOA varied between short (100 ms) and long (800 ms). A Bayesian mixed-model analysis was used to isolate the effects of attention on the probability and the fidelity of colour encoding. Both endogenous and short-SOA exogenous spatial cueing improved the probability of encoding the colour of targets. Improved fidelity of encoding was observed in the endogenous but not in the exogenous cueing paradigm. With exogenous cues, inhibition of return (IOR) was observed in both RT and probability at the long SOA. Overall, our findings reinforce the utility of continuous response variables in the research of attention.

Résumé :

Two accounts of the recently reported high workload associated with vigilance tasks (Warm, Dember, & Hancock, 1996) are the direct-cost and indirect-cost views. The former attributes this effect to the need for continuous observing in discriminating signals from noise; the latter attributes the effect to combating the boredom associated with vigilance tasks. These opposing views were tested by providing monitors with reliable cueing which rendered observing necessary only when low probability critical signals were imminent. On the basis of the direct-cost model, it was anticipated that cueing would lead to low workload but high boredom, since observers would have little to do during most of the vigil; the indirect-cost model would lead to a prediction of both high workload and high boredom. The results clearly supported the direct cost view that the workload of vigilance is task induced. Also as predicted from the direct cost account, cueing led to lower workload than did knowledge of results.

Résumé :

Abstract. It is well established in the working memory literature, that performance can be improved by cueing attention toward the position of a to-be-tested item, even after that item’s presentation. This retro-cue benefit is often characterized as the joint outcome of two different effects: facilitation of recall and memory strengthening at the cued position. While the latter has been mainly explained by increased context-content binding, competing hypotheses exist to explain the facilitation of recall. The present study focuses on two of these hypotheses: the removal of non-cued information and the protection of cued information against interference. I replicate the retro-cue effect for verbal material and provide strong evidence for its protective effect. However, I did not find support for the removal hypothesis. This lack of support follows from two empirical findings: Retro-cueing does not decrease, rather increases the conditional probability of intrusions, and the retro-cue benefit does not interact with memory load.

Résumé :

Prior information about the relevance of spatial locations can vary in specificity; a single location, a subset of locations, or all locations may be of potential importance. Using a contrast-discrimination task with four possible targets, we asked whether performance benefits are graded with the spatial specificity of a prior cue and whether we could quantitatively account for behavioral performance with cortical activity changes measured by blood oxygenation level-dependent (BOLD) imaging. Thus we changed the prior probability that each location contained the target from 100 to 50 to 25% by cueing in advance 1, 2, or 4 of the possible locations. We found that behavioral performance (discrimination thresholds) improved in a graded fashion with spatial specificity. However, concurrently measured cortical responses from retinotopically defined visual areas were not strictly graded; response magnitude decreased when all 4 locations were cued (25% prior probability) relative to the 100 and 50% prior probability conditions, but no significant difference in response magnitude was found between the 100 and 50% prior probability conditions for either cued or uncued locations. Also, although cueing locations increased responses relative to noncueing, this cue sensitivity was not graded with prior probability. Furthermore, contrast sensitivity of cortical responses, which could improve contrast discrimination performance, was not graded. Instead, an efficient-selection model showed that even if sensory responses do not strictly scale with prior probability, selection of sensory responses by weighting larger responses more can result in graded behavioral performance benefits with increasing spatial specificity of prior information.

Résumé :

Motor readiness, visual attention, and reaction time (RT) were assessed in 15 elite table tennis players (TTP) and 15 controls (C) during Posner’s cued attention task. Lateralized readiness potentials (LRP) were derived from contingent negative variation (CNV) at Sites C3 and C4, elicited between presentation of directional cueing (S1) and the appearance of the imperative stimulus (S2), to assess preparation for hand movement while P1 and N1 component amplitudes were derived from occipital event-related potentials (ERPs) in response to S2 to assess visual attention. Both groups had faster RT to validly cued stimuli and slower RT to invalidly cued stimuli relative to the RT to neutral stimuli that were not preceded by directional cueing, but the groups did not differ in attention benefit or cost. However, TTP did have faster RT to all imperative stimuli; they maintained superior reactivity to S2 whether preceded by valid, invalid, or neutral warning cues. Although both groups generated LRP in response to the directional cues, TTP generated larger LRP to prepare the corresponding hand for movement to the side of the cued location. TTP also had an inverse cueing effect for N1 amplitude (i.e., amplitude of N1 to the invalid cue > amplitude of N1 to the valid cue) while C visually attended to the expected and unexpected locations equally. It appears that TTP preserve superior reactivity to stimuli of uncertain location by employing a compensatory strategy to prepare their motor response to an event associated with high probability, while simultaneously devoting more visual attention to an upcoming event of lower probability.

Résumé :

The use of a mnemonic cueing system (NeuroPage®) and a paper and pencil checklist in the rehabilitation of executive problems in a 50-year-old woman are described. Following a CVA 7 years earlier, the patient, despite intact general intellectual and memory functioning, had specific executive impairments of attention, planning, realizing intended actions, and also exhibited behavioral routines similar in form to obsessive–compulsive rituals. In a series of ABAB single-case experimental designs, the efficacy of 2 external cueing systems in prompting appropriately timed action is demonstrated. It is argued that the combination of external control and increased sustained attention to action were critical to the success of NeuroPage with this patient. Furthermore it is hypothesized that the checklist was effective in facilitating the patient's ability to foresee and recognize the consequences of her actions, which in turn had an impact on the probability of her changing those same actions.

Résumé :

Listeners build up statistically driven expectations of what they will hear; however, there is no consensus on how these statistics influence perception, attention, and behavior. Here, we manipulate two statistical properties: global probability (the likelihood of single ‘sound events’) and predictiveness (how often does one sound precede another). We ask how the probability and predictiveness of different acoustic frequencies affect performance on two paradigms where frequency is task-irrelevant: suprathreshold duration identification and near-threshold tone-detection-in-noise. We found that duration decisions are faster and detection decisions are more accurate for high-probability tone frequencies, compared to low-probability tone frequencies. Moreover, when a preceding “cue” tone’s frequency predicts that of a subsequent “target” tone, listeners are faster at judging the duration of the target tone. This latter effect is not solely a result of temporal cueing, as target responses are not facilitated if a cue does not predict the target tone’s frequency. Blending these paradigms to examine the same global and transitional probabilities across duration and detection decisions suggests that statistical learning shapes attention to perceptual dimensions, even when the dimensions are irrelevant to optimal task performance.

Résumé :

Here we examined the relationship between inhibition of return (IOR) and response-selection conflict. In two go/no-go and spatial-cueing experiments, we measured the amplitude of the fronto-central N2 event-related potential component to estimate the degree of response-selection conflict for validly cued and invalidly cued targets. When the probability of a go target was high (Experiment 1), both the amplitude of the N2 elicited on no-go trials and the number of false alarm errors were greater on invalid-cue than on valid-cue trials. When the probability of a go target was low (Experiment 2), neither of these effects was observed and the magnitude of the IOR effect was greatly reduced. These results show that a relative response bias toward responding on invalid-cue trials contributes to the IOR reaction time effect when the required response is prepotent.

Résumé :

The abrupt onset of a novel event captures attention away from, and disrupts, ongoing task performance. Less obvious is that intentional task switching compares with novelty-induced behavioral distraction. Here we explore the hypothesis that intentional task switching and attentional capture by a novel distracter both activate a common neural network involved in processing contextual novelty [Barcelo, F., Periáñez, J. A., & Knight, R. T. Think differently: A brain orienting response to task novelty. NeuroReport, 13, 1887–1892, 2002.]. Event-related potentials were recorded in two task-cueing paradigms while 16 subjects sorted cards following either two (color or shape; two-task condition) or three (color, shape, or number; three-task condition) rules of action. Each card was preceded by a familiar tone cueing the subject either to switch or to repeat the previous rule. Novel sound distracters were interspersed in one of two blocks of trials in each condition. Both novel sounds and task-switch cues impaired responses to the following visual target. Novel sounds elicited novelty P3 potentials with their usual peak latency and frontal-central scalp distribution. Familiar tonal switch cues in the three- and two-task conditions elicited brain potentials with a similar latency and morphology as the novelty P3, but with relatively smaller amplitudes over frontal scalp regions. Covariance and principal component analyses revealed a sustained frontal negative potential that was distorting concurrent novelty P3 activity to the tonal switch cues. When this frontal negativity was statistically removed, P3 potentials to novel sounds and task-switch cues showed similar scalp topographies. The degree of activation in the novelty P3 network seemed to be a function of the information (entropy) conveyed by the eliciting stimulus for response selection, over and above its relative novelty, probability of occurrence, task relevance, or feedback value. We conclude that novelty P3 reflects transient activation in a neural network involved in updating task set information for goal-directed action selection and might thus constitute one key element in a central bottleneck for attentional control.

Résumé :

Joint attention is a communicative activity that allows social partners to share perceptual experiences by jointly attending to an environmental object. Unlike the common approach towards joint attention, which is based on the developmental view in robotics, here it is conceptualized with a psychophysical paradigm known as cueing. The triadic interaction of joint attention is formalized as the conditional probability of an attentional response for a given target candidate derived from object features and a cue derived from a human partner's indication. A robotic system to which the joint attention model is applied conducted a series of tasks to demonstrate the properties of the computational model. The robotic system successfully performed the tasks, which could not be specified by the information derived from a target object alone; furthermore, the system demonstrated how perceptual and selection ambiguity is resolved through joint attentive interaction and made to converge into a common perceptual state. The results imply that a perceptual common ground is constructed on the triadic relationship between user, robot, and objects through joint attentive interaction.

Résumé :

Close behavioural coupling of visual orientation may provide a range of adaptive benefits to social species. In order to investigate the natural properties of gaze-following between pedestrians, we displayed an attractive stimulus in a frequently trafficked corridor within which a hidden camera was placed to detect directed gaze from passers-by. The presence of visual cues towards the stimulus by nearby pedestrians increased the probability of passers-by looking as well. In contrast to cueing paradigms used for laboratory research, however, we found that individuals were more responsive to changes in the visual orientation of those walking in the same direction in front of them (i.e. viewing head direction from behind). In fact, visual attention towards the stimulus diminished when oncoming pedestrians had previously looked. Information was therefore transferred more effectively behind, rather than in front of, gaze cues. Further analyses show that neither crowding nor group interactions were driving these effects, suggesting that, within natural settings gaze-following is strongly mediated by social interaction and facilitates acquisition of environmentally relevant information.

Résumé :

Abstract Attention (i.e., task relevance) and expectation (i.e., signal probability) are two critical top-down mechanisms guiding perceptual inference. Attention prioritizes processing of information that is relevant for observers’ current goals. Prior expectations encode the statistical structure of the environment. Research to date has mostly conflated spatial attention and expectation. Most notably, the Posner cueing paradigm manipulates spatial attention using probabilistic cues that indicate where the subsequent stimulus is likely to be presented. Only recently have studies attempted to dissociate the mechanisms of attention and expectation and characterized their interactive (i.e., synergistic) or additive influences on perception. In this review, we will first discuss methodological challenges that are involved in dissociating the mechanisms of attention and expectation. Second, we will review research that was designed to dissociate attention and expectation in the unisensory domain. Third, we will review the broad field of crossmodal endogenous and exogenous spatial attention that investigates the impact of attention across the senses. This raises the critical question of whether attention relies on amodal or modality-specific mechanisms. Fourth, we will discuss recent studies investigating the role of both spatial attention and expectation in multisensory perception, where the brain constructs a representation of the environment based on multiple sensory inputs. We conclude that spatial attention and expectation are closely intertwined in almost all circumstances of everyday life. Yet, despite their intimate relationship, attention and expectation rely on partly distinct neural mechanisms: while attentional resources are mainly shared across the senses, expectations can be formed in a modality-specific fashion.

Résumé :

Large-scale search behaviour is an everyday occurrence, yet its underlying mechanisms are not commonly examined within experimental psychology. Key to efficient search behaviour is the sensitivity to environmental cues that might guide exploration, such as a target appearing with greater regularity in one region than another. Spatial cueing by probability has been examined in visual search paradigms, but the few studies that have addressed its contribution to large-scale search and foraging present contrasting accounts of the conditions under which a cueing effect can be reliably observed. In the present study, participants physically searched a virtual arena by inspecting identical locations until they found the target. The target was always present, although its location was probabilistically defined so that it appeared in the cued hemispace on 80% of trials. In Experiment 1, when participants’ starting positions were stable, a probabilistic cueing effect was observed, with a strong bias towards searching the cued side. In Experiment 2, the starting position changed across the experiment, such that the cued region was defined in allocentric co-ordinates only. In this case, a probabilistic cueing effect was not observed across the sample. Analysis of individual differences in Experiment 2 suggests, however, that some participants may have learned the contingency underpinning the target’s location, although these differences were unrelated to other tests of visuospatial ability. These results suggest that the ability to learn the likelihood of an item’s fixed location when starting from different perspectives is driven by individual differences in other cognitive or perceptual factors.

Résumé :

Inhibition of return (IOR) refers to the phenomenon that a person is slower to respond to targets at a previously cued location. The present study aimed to explore whether target-reward association is subject to IOR, using event-related potentials (ERPs) to explore the underlying neural mechanism. Each participant performed a localization task and a color discrimination task in an exogenous cueing paradigm, with the targets presented in colors (green/red) previously associated with high- or low-reward probability. The results of both tasks revealed that the N1, Nd, and P3 components exhibited differential amplitudes between cued and uncued trials (i.e., IOR) under low reward, with the N1 and Nd amplitudes being enhanced for uncued trials compared to cued trials, and the P3 amplitude being enhanced for cued trials vs. uncued trials. Under high reward, however, no difference was found between the amplitudes on cued and uncued trials for any of the components. These findings demonstrate that targets that were previously associated with high reward can be resistant to IOR and the current results enrich the evidence for interactions between reward-association and attentional orientation in the cueing paradigm.

Résumé :

Abstract In this report we present a mobile brain/body imaging (MoBI) dataset that allows study of source-resolved cortical dynamics supporting coordinated gait movements in a rhythmic auditory cueing paradigm. Use of an auditory pacing stimulus stream has been recommended to identify deficits and treat gait impairments in neurologic populations. Here, the rhythmic cueing paradigm required healthy young participants to walk on a treadmill (constant speed) while attempting to maintain step synchrony with an auditory pacing stream and to adapt their step length and rate to unanticipated shifts in tempo of the pacing stimuli (e.g., sudden shifts to a faster or slower tempo). High-density electroencephalography (EEG, 108 channels), surface electromyography (EMG, bilateral tibialis anterior), pressure sensors on the heel (to register timing of heel strikes), and goniometers (knee, hip, and ankle joint angles) were concurrently recorded in 20 participants. The data is provided in the Brain Imaging Data Structure (BIDS) format to promote data sharing and reuse, and allow the inclusion of the data into fully automated data analysis workflows.

Résumé :

The visual world is extremely complex, so unconscious mechanisms exist to autonomously direct attention to objects with behavioral importance. One such mechanism – contextual cueing – utilizes the visual context of a scene to focus attention. Therefore, because contextual information unconsciously influences human visual perception, its role in enabling individuals to process scenes is of great interest. This study examined whether contextual information regarding change probability can facilitate the process of change identification. MATLAB and Psychophysics Toolbox Version 3 were used to present abstract scenes in a one-shot change blindness paradigm. Two types of scenes were presented: one in which context was predictive of change likelihood, the other in which context was non-predictive of change likelihood. The accuracy with which subjects detected and localized changes in both scene types was compared, but no significant difference in accuracy was found. This observation suggests that contextual information regarding change probability alone is insufficient to improve the change identification accuracy. Subsequently, it may be that even when individuals are aware that a visual scene is likely to change, they still require additional contextual cues to improve change identification.

Résumé :

Attention may be a significant precursor to visual awareness but does not fulfil the sufficiency test. Moreover, the study uses a Posner endogenous spatial cueing paradigm to show that the time taken by the subject to discriminate the point of reference of a stimulus is minimized if the individual is signal towards the location of the stimulus. The reaction-time advantage is achieved without any reduction in discrimination accuracy. It implies that it cannot be said to have been caused by the speed-error trade off or distinctions in bias between the cued and uncued locations. Therefore, the subject was unaware of the stimuli to which processing was attenionally directed. In the end, the researchers conclude that attention is not a satisfactory condition for awareness.

Résumé :

This research investigates the relationship between couples’ work-orientation incongruence—the degree to which romantic partners view the meaning of their own work differently—and their ability to succeed in making job transitions and experiencing satisfaction with the jobs they hold. We use a social information-processing approach to develop arguments that romantic partners serve as powerful social referents in the domain of work. By cueing social information regarding the salience and value of different aspects of work, partners with incongruent work orientations can complicate each other’s evaluation of their own jobs and the jobs they seek. In a longitudinal study of couples in which one partner is searching for work, we find that greater incongruence in couples’ calling orientations toward work relates to lower reemployment probability, a relationship that is mediated by an increased feeling of uncertainty about the future experienced by job seekers in such couples. Calling-orientation incongruence also relates to lower job satisfaction for employed partners over time. We contribute to the burgeoning literature on the role romantic partners play in shaping work outcomes by examining the effect of romantic partners’ perception of the meaning of work, offering empirical evidence of the ways in which romantic partners influence key work and organizational outcomes. Our research also contributes to the meaning of work literature by demonstrating how work-orientation incongruence at the dyadic level matters for individual work attitudes and success in making job transitions.
