Abstract:
Purpose: The purpose of this study is to further explore the relationship between the frequency of stuttering measured in percentage of syllables stuttered (%SS) and perceptual ratings of stuttering severity by the clinician and the client in a clinical setting. Method: Eight adolescent and adult participants attending a stuttering therapy program and their graduate student clinicians perceptually rated stuttering severity using a 9‐point scale. Speech samples were gathered during each therapy session for a total of 167 speech samples. Further, each sample was analyzed for %SS. A Pearson Product Moment Correlation (PPMC) was used to determine the strength and direction of correlations between %SS and perceptual ratings by the clinician and client. Results: The correlational analysis indicates significant positive correlations between perceptual severity ratings by the clinician and client as well as %SS. Correlation between perceptual ratings was stronger than the correlation between perceptual ratings and %SS. Conclusion: The strong, positive correlation between the client's self‐measurement and the clinician's perceptual measurement indicates similarities in global severity of stuttering perception. Weaker correlation between %SS and perceptual ratings indicates the need to incorporate a more holistic measure of stuttering severity. Implication and directions for future research are discussed.

Abstract:
This paper describes three psychoacoustic experiments that evaluated the perceptual quality of sounds generated from a new wavelet-based synthesis technique. The synthesis technique provides a method for modeling and synthesizing perceptually compelling sound. The experiments define a methodology for evaluating the effectiveness of any synthesized sound. An identification task and a context-based rating task evaluated the perceptual quality of individual sounds. These experiments confirmed that the wavelet technique synthesizes a wide variety of compelling sounds from a small model set. The third experiment obtained sound similarity ratings. Psychological scaling methods were applied to the similarity ratings to generate both spatial and network models of the perceptual relations among the synthesized sounds. These analysis techniques helped to refine and extend the sound models. Overall, the studies provided a framework to validate synthesized sounds for a variety of applications including virtual reality and data sonification systems.

Abstract:
A rating instrument is described that can be used to assess the results of stuttering treatments. The instrument is designed for use with naive listeners. It yields a comprehensive and detailed description of the speech quality in terms of articulation, phonation, pitch, and loudness; in addition, it includes a naturalness scale. Analysis of ratings obtained with the instrument show that naturalness is a multidimensional characteristic. Moreover, the speech characteristics that determine the naturalness ratings appear to be different pretreatment, posttreatment, and at follow-up treatment. The psychometric characteristics of the instrument are analyzed in detail. It is concluded that mixing of samples of stutterers and nonstutterers in one rating experiment may artificially inflate the reliability of the ratings. Also, ratings on equal-appearing interval scales cannot be interpreted in an absolute sense. Solutions for this methodological problem are suggested.

Abstract:
The purpose of this study was to examine the reliability of ratings of perceptual characteristics for 10 ataxic dysarthric subjects. The influence of the occurrence of "deviant" speech parameters on the calculation of reliability coefficients was also explored. Results indicated that overall interobserver agreement levels for minimally trained judges compared favorably to reliability coefficients reported in previous studies. Furthermore, levels of overall agreement were above levels of agreement expected on the basis of chance alone. In contrast to overall interobserver agreement, much lower levels of interobserver agreement were obtained when "occurrence Reliability" coefficients were calculated for deviant dimensions alone. However, occurrence reliability coefficients surpassed the level of agreement expected on the basis of chance alone for all subjects. Based on the results of this investigation, recommendations are made for modifying standard practices for obtaining interobserver reliability for perceptual ratings of speech characteristics.

Abstract:
Objective This investigation studied the effects of perceptual anchors on the dispersion and reliability of listener ratings of nasality. Design Listeners (N = 129) were assigned to one of six listening groups. Each group rated nasality independently for 100 speech samples on a seven-point scale that ranged from 1 = normal nasality to 7 = severe hypernasality. The anchors used were examples of a 1, 3, 4, 5, and/or 7 on the rating scale. These anchors were played selectively to group 2 (4), group 3 (1 and 7), group 4 (3 and 5), group 5 (1, 4, 7), and group 6 (7). Group 1 had no anchor. Participants Of the speakers, 95 were children followed by a craniofacial team and five were children without histories of speech disorders. Main Outcome Measures The outcome measures were 12,900 ratings of nasality on a seven-point scale. Results Q values showed that group 5, which was the only group to receive three anchors, had the lowest, or best, Q value (0.78), and group 1 (no anchor) had the highest, or worst, Q value (0.99). Across groups, the most reliable ratings were those at scale values 1 (Q = 0.46) and 7 (Q = 0.56). The least reliable ratings were at scale values 3 (Q = 1.01), 4 (Q = 1.03), and 5 (Q = 1.06). Conclusions Nasality rating reliability/dispersion was influenced by the presence and location of anchor stimuli. Consistent with absolute judgment theory, nasality ratings showed a strong end effect.

Abstract:
The reliability of listeners’ ratings of voice quality is a central issue in voice research because of the clinical primacy of such ratings and because they are the standard against which other measures are evaluated. However, an extensive literature review indicates that both intrarater and interrater reliability fluctuate greatly from study to study. Further, our own data indicate that ratings of vocal roughness vary widely across individual clinicians, with a single voice often receiving nearly the full range of possible ratings. No model or theoretical framework currently exists to explain these variations, although such a model might guide development of efficient, valid, and standardized clinical protocols for voice evaluation. We propose a theoretical framework that attributes variability in ratings to several sources (including listeners’ backgrounds and biases, the task used to gather ratings, interactions between listeners and tasks, and random error). This framework may guide development of new clinical voice and speech evaluation protocols, ultimately leading to more reliable perceptual ratings and a better understanding of the perceptual qualities of pathological voices.

Abstract:
Purpose The strength of the relationship between vowel centralization measures and perceptual ratings of dysarthria severity has varied considerably across reports. This article evaluates methods of acoustic-perceptual analysis to determine whether procedural changes can strengthen the association between these measures. Method Sixty-one speakers (17 healthy individuals and 44 speakers with dysarthria) read a standard passage. To obtain acoustic data, 2 points of formant extraction (midpoint and articulatory point) and 2 frequency measures (Hz and Bark) were trialed. Both vowel space area and an adapted formant centralization ratio were calculated using first and second formants of speakers' corner vowels. Twenty-eight listeners rated speech samples using different prompts: one with a focus on intelligibility, the other on speech precision. Results Perceptually, listener ratings of speech precision provided the best index of acoustic change. Acoustically, the combined use of an articulatory-based formant extraction point, Bark frequency units, and the formant centralization ratio was most effective in explaining perceptual ratings. This combination of procedures resulted in an increase of 17% to 27% explained variance between measures. Conclusions The procedures researchers use to assess articulatory impairment can significantly alter the strength of relationship between acoustic and perceptual measures. Procedures that maximize this relationship are recommended.

Abstract:
Purpose: Aphasia fluency is multiply determined by underlying impairments in lexical retrieval, grammatical formulation, and speech production. This poses challenges for establishing a reliable and feasible tool to measure fluency in the clinic. We examine the reliability and validity of perceptual ratings and clinical perspectives on the utility and relevance of methods used to assess fluency. Method: In an online survey, 112 speech-language pathologists rated spontaneous speech samples from 181 people with aphasia (PwA) on eight perceptual rating scales (overall fluency, speech rate, pausing, effort, melody, phrase length, grammaticality, and lexical retrieval) and answered questions about their current practices for assessing fluency in the clinic. Results: Interrater reliability for the eight perceptual rating scales ranged from fair to good. The most reliable scales were speech rate, pausing, and phrase length. Similarly, clinicians' perceived fluency ratings were most strongly correlated to objective measures of speech rate and utterance length but were also related to grammatical complexity, lexical diversity, and phonological errors. Clinicians' ratings reflected expected aphasia subtype patterns: Individuals with Broca's and transcortical motor aphasia were rated below average on fluency, whereas those with anomic, conduction, and Wernicke's aphasia were rated above average. Most respondents reported using multiple methods in the clinic to measure fluency but relying most frequently on subjective judgments. Conclusions: This study lends support for the use of perceptual rating scales as valid assessments of speech-language production but highlights the need for a more reliable method for clinical use. We describe next steps for developing such a tool that is clinically feasible and helps to identify the underlying deficits disrupting fluency to inform treatment targets.

Abstract:
The purpose of this pilot study was to investigate adult Ineraid and Nucleus cochlear implant (CI) users’ perceptual accuracy for melodic and rhythmic patterns, and quality ratings for different musical instruments. Subjects were 18 postlingually deafened adults with CI experience. Evaluative measures included the Primary Measures of Music Audiation (PMMA) and a Musical Instrument Quality Rating. Performance scores on the PMMA were correlated with speech perception measures, music background, and subject characteristics. Results demonstrated a broad range of perceptual accuracy and quality ratings across subjects. On these measures, performance for temporal contrasts was better than for melodic contrasts independent of CI device. Trends in the patterns of correlations between speech and music perception suggest that particular structural elements of music are differentially accessible to cochlear implant users. Additionally, notable qualitative differences for ratings of musical instruments were observed between Nucleus and Ineraid users

Abstract:
The purpose of this study was to determine the validity and reliability of using perceptual ratings for assessing voice quality in patients with vocal fold nodules or polyps. A 13-dimension perceptual rating system was modeled after systems currently in clinical use. To meet the criterion of 80% mean interjudge reliability, eight hours of training were required for four previously inexperienced listeners. Extended vowel phonations of patients and controls were then rated blindly by the same listeners. Interjudge reliability was greater than .90 for three dimensions judged in the pathological phonations, while intrajudge test-retest agreement was less than 75% on five dimensions. Validity was demonstrated with 100% correct assignment to group by computing a discriminant function employing all dimensions. Despite the extensive training procedures used, our reliability data were not comparable to those reported when highly experienced judges have been used, suggesting that the task of perceptually rating voice quality is difficult and requires extensive professional experience.

Abstract:
The technique of �open throat� is a pedagogical concept transmitted through the oral tradition of singing. This thesis explored the pedagogical perceptions and practices of �open throat� using empirical methodologies to assess technical skill and associated vocal quality. In the first study (Mitchell, Kenny, Ryan, & Davis, 2003), we assessed the degree of consensus amongst singing pedagogues regarding the definition of, and use in the singing studio of the technique called �open throat.� Results indicated that all fifteen pedagogues described �open throat� technique as fundamental to singing training and were positive about the sound quality it achieved, especially in classical singing. It was described as a way of maximising pharyngeal space or abducting the false vocal folds. Hypotheses generated from pedagogical beliefs expressed in this first study were then tested acoustically (Mitchell & Kenny, 2004a, 2004b). Six advanced singing students sang in two conditions: �optimal� (O), using maximal open throat, �sub-optimal� (SO), using reduced open throat and loud sub-optimal (LSO) to control for the effect of loudness. From these recordings, acoustic characteristics of vibrato (Mitchell & Kenny, 2004b) and energy distribution (Mitchell & Kenny, 2004a) were examined. Subsequent investigations of the vibrato parameters of rate, extent and onset, revealed that extent was significantly reduced and onset increased when singers did not use the technique. As inconsistent vibrato is considered indicative of poor singing, it was hypothesized that testing the energy distribution in these singers� voices in each condition would identify the timbral changes associated with open throat. Visual inspection of long term average spectra (LTAS) confirmed differences between O and SO, but conventional measures applied to long term average spectra (LTAS), comparing energy peak height [singing power ratio (SPR)] and peak area [energy ratio (ER)] were not sensitive to the changes identified through visual inspection of the LTAS. These results were not consistent with the vibrato findings and suggest that conventional measures of SPR and ER are not sufficiently sensitive to evaluate LTAS. In the fourth study, fifteen expert listeners consistently and reliably identified the presence of open throat technique with 87% accuracy (Mitchell & Kenny, in press). In the fifth study, LTAS measurements were examined with respect to the perceptual ratings of singers. There was no relationship between perceptual rankings of vocal beauty and acoustic rankings of vocal quality (Kenny & Mitchell, 2004, in press). There is a vast literature of spectral energy definitions of good voice but the studies in this thesis have indicated that current acoustic methods are limited in defining vocal quality. They also suggest that current work in singing has not sufficiently incorporated perceptual ratings and descriptions of sound quality or the relationship between acoustic and perceptual factors with pedagogical practices.

Abstract:
The purpose of this investigation was to compare associative and dissociative psychological strategies of attentional focus for their effects on self - report ratings of perceived exertion (RPE), and heart rate during endurance exercise. Trained cyclists (n = 7) performed three 60 minute experimental rides on a bicycle ergometer which consisted of an association ride (attention focused on heart rate feedback), a dissociation ride (attention focused on responding to a cue word on a videotape), and a control condition ride in which focus of attention was not purposely manipulated. Results indicated that the deliberate application of a cognitive strategy designed to encourage an individual to associate or dissociate did not differentially effect either actual efficiency (heart rate) or perception of exercise intensity (RPE scores). Overall, it was concluded that there was a trend for the dissociation condition to result in higher RPE scores than the association condition or control condition.

Abstract:
Second language (L2) learners of English must learn to produce English phonemes, words, and sentences. These L2 learners make many errors when learning English; they may change the place or manner of articulation, insert vowels, or delete consonants. Obstruent sounds, such as fricatives, affricates, and stops, can be especially difficult for L2 learners. This study analyzed native English speakers<'> perception of the quality of obstruents produced by native Mandarin Chinese and Korean speakers. Target words containing obstruents had been produced in three different tasks: in a carrier phrase, in a paragraph, and in a spontaneous speech sample. Obstruents were produced in word-initial position and word-final position. Raters with differing levels of expertise listened to these words and rated the perceptual quality of the obstruents within the words. This study found that overall, English obstruent productions by native Mandarin and Korean L2 speakers learning English were rated most clear when produced in word-initial position in a carrier phrase or a paragraph. The lowest ratings given were of obstruents in word-final position in spontaneous speech. No significant differences were found for listener expertise level. Combined with future research, results from this study will help educate the field of second language instruction as to how the speech of Korean and Mandarin learners of English is perceived. It also provides additional information on the effect that listener expertise has on the judgment of L2 speech production.

Abstract:
As there is a clear correlation between one's degree of proficiency in the English language and one's subsequent financial compensation in the workplace setting and in interpersonal relationships, improving one's speaking abilities can be highly valuable from both a financial and emotional perspective. This study examines the efficacy of an electropalatography (EPG) assisted pronunciation training program in helping native Japanese learners of English acquire and improve the /r/ and /l/ sound contrast in American English, as rated by a group of listeners. Additionally, it evaluates whether or not the degree of improvement varied across word position, task type, or assessment period. Four native Japanese speaking learners of English participated in a four-week program which included seven 45- minute training sessions enhanced with visual biofeedback from the EPG. Samples of their productions of the target phonemes were obtained at baseline, at posttreatment, and at follow-up assessment periods. Using a visual analogue scale, 36 adult listeners listened to these recordings and provided comparative auditory perceptual ratings. Overall, subjects showed greater improvement in their production of the phoneme /l/ than in the phoneme /r/. Phoneme-specific patterns emerged in terms of word position, task type, and assessment period. For the phoneme /l/, more improvement was seen in final position than initial position, more improvement was seen in nonsense syllables than in words, and improvements were maintained across posttreatment to follow-up assessment periods. For the phoneme /r/, roughly equal levels of improvement were seen across word position, while greater improvement was seen in the context of words in sentences than in nonsense syllables, and posttreatment showed greater levels of improvement than did follow-up assessment periods. These results are promising as it indicates that EPG assisted pronunciation training may be an effective vehicle to help L2 English language learners acquire and improve their productions of the /r/-/l/ phonemic contrast. This is significant, as the Japanese L2 population has typically been found to be highly resistant to more traditional forms of intervention.

Abstract:
How much does stimulus input shape perception? The common-sense view is that our perceptions are representations of objects and their features and that the stimulus structures the perceptual object. The problem for this view concerns perceptual biases as responsible for distortions and the subjectivity of perceptual experience. These biases are increasingly studied as constitutive factors of brain processes in recent neuroscience. In neural network models the brain is said to cope with the plethora of sensory information by predicting stimulus regularities on the basis of previous experiences. Drawing on this development, this chapter analyses perceptions as processes. Looking at olfaction as a model system, it argues for the need to abandon a stimulus-centred perspective, where smells are thought of as stable percepts, computationally linked to external objects such as odorous molecules. Perception here is presented as a measure of changing signal ratios in an environment informed by expectancy effects from top-down processes.

Abstract:
AbstractCrowdsourcing can enable rapid data collection for haptics research, yet little is known about its validity in comparison to controlled lab experiments. Furthermore, no data exists on how different smartphone platforms impact the crowdsourcing results. To answer these questions, we conducted four vibrotactile (VT) similarity perception studies on iOS and Android smartphones in the lab and through Amazon Mechanical Turk (MTurk). Participants rated the pairwise similarities of 14 rhythmic VT patterns on their smartphones or a lab device. The similarity ratings from the lab and MTurk experiments suggested a very strong correlation for iOS devices ($$r_s= 0.9$$ r s = 0.9 ) and a lower but still strong correlation for Android phones ($$r_s= 0.68$$ r s = 0.68 ). In addition, we found a stronger correlation between the crowdsourced iOS and Android ratings ($$r_s=0.78$$ r s = 0.78 ) compared to the correlation between the iOS and Android data in the lab ($$r_s= 0.65$$ r s = 0.65 ). We provide further insights into these correlations using the perceptual spaces obtained from the four datasets. Our results provide preliminary evidence for the validity of crowdsourced VT similarity studies, especially on iOS devices.

Abstract:
AbstractRecently, many new studies emerged to apply computer vision (CV) to street view imagery (SVI) dataset to objectively extract the view indices of various streetscape features such as trees to proxy urban scene qualities. However, human perceptions (e.g., imageability) have a subtle relationship to visual elements which cannot be fully captured using view indices. Conversely, subjective measures using survey and interview data explain more human behaviors. However, the effectiveness of integrating subjective measures with SVI dataset has been less discussed. To address this, we integrated crowdsourcing, CV, and machine learning (ML) to subjectively measure four important perceptions suggested by classical urban design theory. We first collected experts’ rating on sample SVIs regarding the four qualities which became the training labels. CV segmentation was applied to SVI samples extracting streetscape view indices as the explanatory variables. We then trained ML models and achieved high accuracy in predicting the scores. We found a strong correlation between predicted complexity score and the density of urban amenities and services Point of Interests (POI), which validates the effectiveness of subjective measures. In addition, to test the generalizability of the proposed framework as well as to inform urban renewal strategies, we compared the measured qualities in Pudong to other five renowned urban cores worldwide. Rather than predicting perceptual scores directly from generic image features using convolution neural network, our approach follows what urban design theory suggested and confirms various streetscape features affecting multi-dimensional human perceptions. Therefore, its result provides more interpretable and actionable implications for policymakers and city planners.

This study builds on the Taylor and Brown theory of positive illusions to attain a more in-depth understanding of the relative influence of perceptual congruence and enhanced perception (positive illusions) on relational satisfaction. A sample of 812, organized into 406 subject-partner pairs of 203 married couples, 100 dating couples, and 103 same-sex roommate dyads completed questionnaires. Each subject rated him- or her-self on six personal qualities (social skills, emotional stability, agreeableness, hostility, depression, and spirituality) and four temperaments (Dominance, Influence, Supportiveness, Conscientiousness). Then they took tests that measured the same qualities to compare with the self-ratings. On another questionnaire, each partner rated the subject on the same 10 qualities. Both subjects and partners completed the Dyadic Adjustment Scale as the measure of relational satisfaction. Primary findings discovered that in most cases, positive illusions diminish relational satisfaction. The only setting in which benefit occurs is when partners rate subjects higher than subjects rate themselves. Congruence between ratings (whether subject-test, partner-test or subject-partner) is strongly associated with relational success. Findings contrast with the Taylor and Brown theory and provide a more nuanced look at the influence of enhancement or congruence.

Abstract:
This paper aims to research the hospitality industry to gauge dimensions of Customer Relationship Management (CRM) that resonate with guests and employees. An uncovering of perceptual differences of hotel guests and employees was sought to assess its application within the London hotel industry and to investigate CRM as an emerging concept. The global hotel market contains many brands and partnerships, and CRM is significant, because differentiation becomes easier for those with potential to develop long-term customer relationships. Despite being differentiated by star ratings, most hotels in London offer similar core products and services. In this regard, development of relationships with customers can be considered emphatic to the London hotel industry. Methodologically, triangulation of data and theories was used in this paper to investigate staff and customers. A standardised questionnaire gauged elements regarded as being part CRM with the objective to assess differential CRM perceptions and their relevancy to the hotel industry in contemporary terms. Findings suggest CRM become an integral part of a hotel’s offerings and operations.

Abstract:
According to Plato’s Timaeus the universe is bound together by proportion (analogia). In the 12th-century reception of Plato (and the late-ancient Platonists), the quest to understand the ordered system of natural powers became coterminous with determining both the harmony of nature’s original divine constitution and the creative power that it continues to exert. And just as the world’s body is made continuous and unified by proportional bonds among the elements, so too is the soul structured in accord with numerical ratios, and its powers are thus properly proportioned by similar harmonies. If the perceptual unity of music harmony is, in the words of the Timaeus, an “imitation of divine harmony manifested in mortal motions,” then understanding musical ratios and proportions may provide a key to understanding the powers of both the macrocosm (the universe) and the microcosm (the human body and soul) alike.

Abstract:
Everyone who has browsed the Internet is familiar with the problems involved in finding what they want. From the novice to the most sophisticated user, the challenge is the same: how to identify quickly and reliably the precise Web sites or other documents they seek from within an ever-growing collection of several billion possibilities? This is not a new problem. Vannevar Bush, the successful Director of the Office of Scientific Research and Development, which included the Manhattan project, made a famous public call in The Atlantic Monthly in 1945 for the scientific community in peacetime to continue pursuing the style of fruitful collaboration they had experienced during the war (Bush, 1945). Bush advocated this approach to address the central difficulty posed by the proliferation of information beyond what could be managed by any single expert using contemporary methods of document management and retrieval. Bush’s vision is often cited as one of the early visions of the World Wide Web, with professional navigators trailblazing paths through the literature and leaving sets of linked documents behind them for others to follow. Sixty years later, we have the professional indexers behind Google, providing the rest of us with a magic window into the data. We can type a keyword or two, pause for reflection, then hit the “I’m feeling lucky” button and see what happens. Technically, even though it often runs in a browser, this task is “information retrieval.” One of its fundamental tenets is that the user cannot manage the data and needs to be guided and protected through the maze by a variety of information hierarchies, taxonomies, indexes, and keywords. Information retrieval is a complex research domain. The Association for Computing Machinery, arguably the largest professional organization for academic computing scientists, sponsors a periodic contest in information retrieval, where teams compete to see who has the most effective algorithms. The contest organizers choose or create a document collection, such as a set of a hundred thousand newspaper articles in English, and contestants demonstrate their software’s ability to find the most documents most accurately. Two of the measures are precision and recall: both of these are ratios, and they pull in opposite directions. Precision is the ratio of the number of documents that have been correctly identified out of the number of documents returned by the search. Recall is the ratio of the number of documents that have been retrieved out of the total number in the collection that should have been retrieved. It is therefore possible to get 100% on precision—just retrieve one document precisely on topic. However, the corresponding recall score would be a disaster. Similarly, an algorithm can score 100% on recall just by retrieving all the documents in the collection. Again, the related precision score would be abysmal. Fortunately, information retrieval is not the only technology available. For collections that only contain thousands of entries, there is no reason why people should not be allowed to simply browse the entire contents, rather than being limited to carrying out searches. Certainly, retrieval can be part of browsing—the two technologies are not mutually exclusive. However, by embedding retrieval within browsing the user gains a significant number of perceptual advantages and new opportunities for actions.

Abstract:
This work addresses the design of a preference based system that suggests relevant products to customers. It aims at helping them with their purchase decision (on electronic commerce websites). A use case that consists in making spontaneous recommendations to the customers, on the basis of their previous ratings is described. The product considered to illustrate the approach is a comic. This paper is focused on two recommender approaches. The first approach, “the traditional” approach, is based on the collaborative filtering while the second approach, is based on a new proposed algorithm. Collaborative filtering is a technique to making recommendations by matching people with the same preferences (preferential similarity). The second approach which is proposed is a combination of the traditional collaborative filtering and the perceptual similarities approach between customers (perceptual similarity). Perceptive data include emotional, sensory and semantic ratings of the products. The purpose of this paper is to evaluate the performance of the proposed approach and to compare it with the traditional approach. A test procedure is thus implemented. It consists in simulating customers’ behavior according to a set of products, and to compute a performance criterion of the recommender system, measuring the relevance of the proposed products. The performance of the proposed algorithm is compared with that of the traditional one. The results show that the consideration of perceptual assessments of products by customers generally helps in the relevance of the propositions of the system.

Abstract:
Public transportation is an essential part of many older adults’ lives, but the pandemic presented new challenges for the vulnerable population. Adults aged 65 years and older experienced additional challenges, such as limited mobility options (e.g., lack of buses or trains in service due a combination of government lockdowns, fear of contracting or spreading the virus, and driver shortages in certain areas) because of the pandemic, which may have resulted in more age-related declines in perceptual, cognitive, and physical functioning. This study explores how older adults living in major metropolitan cities in the United States used and perceived public transportation during the COVID-19 pandemic. The research team conducted an online survey through the Amazon Mechanical Turk (MTurk) crowdsourcing marketplace, a platform that offers opportunities to recruit a larger number of participants from diverse geographic locations. 260 respondents completed the survey. Eligibility included: (1) residing in the United States, (2) being aged 55 years or older (the oldest age that can be selected on MTurk), and (3) having an approval rating of 90% or above (i.e., the percentage of the workers’ submitted tasks approved by survey requesters, offered by the MTurk platform). Overall, older adults reported that they had changed travel patterns since the onset of the COVID-19 pandemic, experienced challenges in using public transportation, and expressed concerns about catching the SARS-CoV-2 virus while using public transportation. Mobile technology (e.g., a transportation navigation app) was perceived as a good option for finding public transportation information, but needs improved user experience and accessibility. These findings may help transit agencies develop effective strategies for improving transportation services and increasing policymakers’ awareness of older adults’ need for accessible public transportation.
