The development of voicing categories: A quantitative review of over 40 years of infant speech perception research

Most research on infant speech categories has relied on measures of discrimination. Such work often employs categorical perception as a linking hypothesis to enable inferences about categorization on the basis of discrimination measures. However, a large number of studies with adults challenge the utility of categorical perception in describing adult speech perception, and this in turn calls into question how to interpret measures of infant speech discrimination. We propose here a parallel channels model of discrimination (built on Pisoni and Tash Perception & Psychophysics, 15(2), 285–290, 1974), which posits that both a noncategorical or veridical encoding of speech cues and category representations can simultaneously contribute to discrimination. This can thus produce categorical perception effects without positing any warping of the acoustic signal, but it also reframes how we think about infant discrimination and development. We test this model by conducting a quantitative review of 20 studies examining infants’ discrimination of voice onset time contrasts. This review suggests that within-category discrimination is surprisingly prevalent even in classic studies and that, averaging across studies, discrimination is related to continuous acoustic distance. It also identifies several methodological factors that may mask our ability to see this. Finally, it suggests that infant discrimination may improve over development, contrary to commonly held notion of perceptual narrowing. These results are discussed in terms of theories of speech development that may require such continuous sensitivity.     

Social Contact,Academic Satisfaction,COVID-19 Knowledge,and Subjective Well-being Among Students at Turkish Universities: a Nine-University Sample

Adverse effects of COVID-19 are seen not only on the physical health of infected individuals but also on their subjective well-being. Sudden changes in social lives, lockdowns, and shifts towards online education have had a negative impact on many people, especially university students. As part of an international study, the current study focused on the well-being of students at Turkish universities in relation to social contact, academic satisfaction, and COVID-19 knowledge. A total of 7363 students from nine universities (86.6% from state universities, 71.04% female, and 73.52% at bachelor’s level) participated in an online survey. Results revealed that females had lower levels of subjective well-being and academic satisfaction. According to a mediation model in the study, the relationship between social contact and well-being was mediated by academic satisfaction and COVID-19 knowledge. Our findings can guide future researchers, mental health professionals, universities, and policymakers to understand and improve subjective well-being of university students.

     

Recognition by association: Within‐ and cross‐modality associative priming with faces and voices

Recent literature has raised the suggestion that voice recognition runs in parallel to face recognition. As a result, a prediction can be made that voices should prime faces and faces should prime voices. A traditional associative priming paradigm was used in two studies to explore within‐modality priming and cross‐modality priming. In the within‐modality condition where both prime and target were faces, analysis indicated the expected associative priming effect: The familiarity decision to the second target celebrity was made more quickly if preceded by a semantically related prime celebrity, than if preceded by an unrelated prime celebrity. In the cross‐modality condition, where a voice prime preceded a face target, analysis indicated no associative priming when a 3‐s stimulus onset asynchrony (SOA) was used. However, when a relatively longer SOA was used, providing time for robust recognition of the prime, significant cross‐modality priming emerged. These data are explored within the context of a unified account of face and voice recognition, which recognizes weaker voice processing than face processing.     

The effects of environmental support and secondary tasks on visuospatial working memory

In the present experiments, we examined the effects of environmental support on participants’ ability to rehearse locations and the role of such support in the effects of secondary tasks on memory span. In Experiment 1, the duration of interitem intervals and the presence of environmental support for visuospatial rehearsal (i.e., the array of possible memory locations) during the interitem intervals were both manipulated across four tasks. When support was provided, memory spans increased as the interitem interval durations increased, consistent with the hypothesis that environmental support facilitates rehearsal. In contrast, when environmental support was not provided, spans decreased as the duration of the interitem intervals increased, consistent with the hypothesis that visuospatial memory representations decay when rehearsal is impeded. In Experiment 2, the ratio of interitem interval duration to intertrial interval duration was kept the same on all four tasks, in order to hold temporal distinctiveness constant, yet forgetting was still observed in the absence of environmental support, consistent with the decay hypothesis. In Experiment 3, the effects of impeding rehearsal were compared to the effects of verbal and visuospatial secondary processing tasks. Forgetting of locations was greater when presentation of to-be-remembered locations alternated with the performance of a secondary task than when rehearsal was impeded by the absence of environmental support. The greatest forgetting occurred when a secondary task required the processing visuospatial information, suggesting that in addition to decay, both domain-specific and domain-general effects contribute to forgetting on visuospatial working memory tasks.     

Predictive Relationship Between Parental Beliefs and Accommodation of Pediatric Anxiety

Behavior performed by parents to assist a youth in avoiding or alleviating anxiety, known as accommodation, is ubiquitous among pediatric anxiety disorders and strongly related to poor treatment outcome. According to cognitive-behavioral theory, the beliefs parents hold regarding accommodation should predict parental accommodating behavior. Unfortunately, little is known about the beliefs parents hold regarding accommodation, as there exists no validated measure of this construct. First, the psychometric properties were examined for the Parental Accommodation Scale (PAS), a novel measure of parental accommodating behavior frequency (PAS-Behavior scale) and parental beliefs about accommodation (PAS-Belief scale). Second, the relationship between parental beliefs about accommodation and accommodation frequency was examined. Results provide preliminary evidence of the internal consistency and convergent validity of the PAS. Stronger positive beliefs about accommodation significantly predicted accommodation frequency, even after controlling for youth anxiety severity. Specifically, beliefs that accommodation prevents youth from losing behavioral and emotional control significantly predicted accommodation frequency. Therefore, efforts to decrease accommodation in clinical settings should involve correcting maladaptive parental beliefs about accommodation, with a particular emphasis on beliefs regarding the necessity of accommodation in preventing a youth from losing behavioral and emotional control.     

Asymmetries in perceptions of self and others' hypocrisy: Rethinking the meaning and perception of the construct

This article examines how people recall and describe instances of hypocrisy in their own and others' behavior. Participants (N = 302) provided two written examples. The first example recalled a time when someone called the participant a hypocrite, whereas the other recalled an instance when the participant perceived someone else's behavior as hypocritical. The first goal of the study was to discover if real‐world examples of hypocrisy reflect only mere inconsistency, consistent with the construct's narrow use in psychology, or if they contain other distinctive defining features. A typology was used to code the examples, based loosely on Crisp and Cowton's philosophical distinction between four forms of hypocrisy: direct inconsistency, pretense, blame, and complacency. The second goal was to uncover reliable actor–observer differences in perceptions of hypocrisy. Results indicated that the four forms occur in real‐world examples of both self and others' hypocrisy. Interestingly, a new fifth form, indirect inconsistency, emerged from the data, adding nuance to the initial hypothesis. Finally, several actor–observer differences in perceptions of hypocrisy arose and are discussed. The results indicate that hypocrisy is a much more complicated phenomenon than previously considered and provide the impetus for new areas of research. Copyright © 2014 John Wiley & Sons, Ltd.     

Hearing a face: cross-modal speaker matching using isolated visible speech

An experiment was performed to test whether cross-modal speaker matches could be made using isolated visible speech movement information. Visible speech movements were isolated using a point-light technique. In five conditions, subjects were asked to match a voice to one of two (unimodal) speaking point-light faces on the basis of speaker identity. Two of these conditions were designed to maintain the idiosyncratic speech dynamics of the speakers, whereas three of the conditions deleted or distorted the dynamics in various ways. Some of these conditions also equated video frames across dynamically correct and distorted movements. The results revealed generally better matching performance in the conditions that maintained the correct speech dynamics than in those conditions that did not, despite containing exactly the same video frames. The results suggest that visible speech movements themselves can support cross-modal speaker matching.     

Longitudinal Associations Between Personality Profile Stability and Adjustment in College Students: Distinguishing Among Overall Stability,Distinctive Stability,and Within‐Time Normativeness

ABSTRACT In the present study, longitudinal associations of 3 aspects of personality profile stability (i.e., overall stability, distinctive stability, and within‐time normativeness) with 3 adjustment measures (i.e., depressive symptoms, self‐esteem, and delinquency) were examined, using 4 waves of longitudinal data on a Belgian college sample (N=565). Longitudinal path models revealed strong longitudinal associations between adjustment and overall stability. Subsequent analyses showed that it is not the degree to which one's personality profile consistently diverges from the average personality profile within a population (i.e., distinctive stability) that is related to adjustment but the degree to which a personality profile of an individual matches the average personality profile within the sample at a certain point in time (i.e., within‐time normativeness). The current study thereby underscores the importance of distinguishing normativeness and distinctiveness when examining personality profile stability.
