Rapid facial reactions to emotional facial expressions in typically developing children and children with autism spectrum disorder

Typical adults mimic facial expressions within 1000 ms, but adults with autism spectrum disorder (ASD) do not. These rapid facial reactions (RFRs) are associated with the development of social-emotional abilities. Such interpersonal matching may be caused by motor mirroring or emotional responses. Using facial electromyography (EMG), this study evaluated mechanisms underlying RFRs during childhood and examined possible impairment in children with ASD. Experiment 1 found RFRs to happy and angry faces (not fear faces) in 15 typically developing children from 7 to 12 years of age. RFRs of fear (not anger) in response to angry faces indicated an emotional mechanism. In 11 children (8-13 years of age) with ASD, Experiment 2 found undifferentiated RFRs to fear expressions and no consistent RFRs to happy or angry faces. However, as children with ASD aged, matching RFRs to happy faces increased significantly, suggesting the development of processes underlying matching RFRs during this period in ASD.     

The influence of irrelevant stimulus changes on stimulus and response repetition effects

In this study the influence of irrelevant stimulus changes from one trial to another in a serial reaction time task was investigated. Two experiments were performed in which subjects were required to respond to stimulus colour. Four colours were mapped on two response keys, so that colour and response repetition effects could be dissociated. In Experiment 1, the irrelevant stimulus dimension was location and in Experiment 2 it was shape. Both experiments were performed with a short and a long response-stimulus interval (RSI)-condition. In both experiments, the irrelevant dimension influenced the response repetition effect but not the colour repetition effect. In the reaction times, a response alternation effect was observed only when the irrelevant location of the stimulus changed in the long RSI-condition. The error rates showed a response alternation benefit for both irrelevant dimensions, in the short and the long RSI-condition. The benefit for response alternations is explained in terms of a response bias towards change that is triggered by a changing stimulus feature. We assume that the response bias is stronger for location than for colour and that accuracy is more sensitive to this bias than response latencies.     

Cognitive mechanisms underlying lying to questions: response time as a cue to deception

In this article, a model of the cognitive processes involved in generating deceptive answers to questions is proposed. Partly based on recent accounts of discourse processing, it posits two central processes. One is the decision to lie followed by the construction of a lie. Each should add to response time compared to answering honestly. In Experiment 1, the construction component was assessed; 92 adults were randomly assigned to one of two conditions where they answered personal questions either deceptively or truthfully. Constructing a lie added reliably to response time. Think‐aloud and correlational data support features of the model. In Experiment 2, 121 adults were randomly assigned to one of three conditions: either to tell the truth, lie, or lie when asked a question that probed sensitive information. Replicating and extending Experiment 1, the decision to lie added reliably to response time in the case of open‐ended questions (questions that elicit more than two possible answers). Based on between‐ and within‐subjects comparisons, results suggest that response time is a cue to deception. Recommendations are made for future research.

Promoting Preschoolers’ Emotional Competence Through Prosocial TV and Mobile App Use

This study explored the relationship between preschoolers’ exposure to Daniel Tiger’s Neighborhood television programming and its accompanying mobile app and preschoolers’ emotion knowledge and use of emotion regulation strategies. An experiment involving 121 parent-child dyads from 3 US metro areas found that children who played with the Daniel Tiger’s Neighborhood app, and those who both played with the app and watched episodes of the program, employed the emotion regulation strategies taught by Daniel Tiger’s Neighborhood media more frequently 1 month later than children in a control condition. Preschoolers (3- and 4-year-olds) also exhibited higher levels of emotion knowledge 1 month after playing with the app. In addition, watching Daniel Tiger’s Neighborhood TV episodes in the home led to increases in parents’ provision of active mediation. Implications for families, educators, and producers of educational media content are discussed.     

Utility of the REDFLAGS Model for Supporting Community College Students’ Mental Health: Implications for Counselors

The counseling literature is lacking in research on supporting the mental health needs of the growing community college student population. A number of past investigators have demonstrated the utility of mental health literacy for supporting college students’ mental health on 4‐year universities. The present researchers examined the validity of the REDFLAGS model (a theoretical model for promoting mental health literacy) with a national stratified random sample (N = 640, stratified by age, gender, and ethnicity) of community college students. Collectively, the results of the confirmatory factor analysis, hierarchical logistic regression, and factorial analysis of variance supported the use of the model with community college students. Implications for enhancing counseling practice as well as directions for future research are provided.     

Toward a comprehensive model of face impressions: What we know,what we do not,and paths forward

A person's impression of another depends upon three sources of variance. The characteristics of the target, the characteristics of the perceiver, and the interplay between the two. Researchers have dedicated different amounts of study to these three sources of variance, and therefore they differ in how well they are understood. The present work will first review the portions of the face impression process that are understood well, then identify and discuss portions of the process less well understood. We will then question to what extent the current state of knowledge will generalize to novel targets and populations. Finally, we will review several modeling approaches that can accommodate relatively unexamined yet important sources of variance in impression formation, suggesting a clear path forward toward a comprehensive understanding of face impressions.     

Relating print and speech: the effects of letter names and word position on reading and spelling performance

From an early age, children can go beyond rote memorization to form links between print and speech that are based on letter names in the initial positions of words (Treiman & Rodriguez, 1999; Treiman, Sotak, & Bowman, 2001). For example, children's knowledge of the name of the letter t helps them learn that the novel word TM is pronounced as team. Four experiments were carried out to determine whether letter names at the ends of words are equally useful. Four- and five-year-olds derived little benefit from such information in reading (Experiments 1 and 3) or spelling (Experiment 2), although adults did (Experiment 4). For young children, word-final information appears to have less influence on reading and spelling performance than does word-initial information. The results help delineate the circumstances under which children can go beyond a logographic approach in learning about print.     

Correlations for organizational,nonorganizational, and intrinsic religiosity with social support among intercollegiate athletes

The present study was a preliminary examination of the correlations among organizational, nonorganizational, and intrinsic religiosity and social support as measured by the Duke Religion Index and the Nonsupport scale of the Personality Assessment Inventory for 105 intercollegiate athletes (51 women). Scores among these measures were not correlated (-.05 to -.14).     

Repetition blindness has a perceptual locus: evidence from online processing of targets in RSVP streams

Four experiments tested whether repetition blindness (RB; reduced accuracy reporting repetitions of briefly displayed items) is a perceptual or a memory-recall phenomenon. RB was measured in rapid serial visual presentation (RSVP) streams, with the task altered to reduce memory demands. In Experiment 1 only the number of targets (1 vs. 2) was reported, eliminating the need to remember target identities. Experiment 2 segregated repeated and nonrepeated targets into separate blocks to reduce bias against repeated targets. Experiments 3 and 4 required immediate "online" buttonpress responses to targets as they occurred. All 4 experiments showed very strong RB. Furthermore, the online response data showed clearly that the 2nd of the repeated targets is the one missed. The present results show that in the RSVP paradigm, RB occurs online during initial stimulus encoding and decision making. The authors argue that RB is indeed a perceptual phenomenon.     

The priming of face recognition after metric transformations

Four experiments were performed to test whether the perceptual priming of face recognition would show invariance to changes in size, position, reflectional orientation (mirror reversal), and picture-plane rotation. In all experiments, subjects recognized faces in two blocks of trials; in the second block, some of the faces were identical to those in the first, and others had undergone metric transformations. The results show that subjects were equally fast to recognize faces whether or not the faces had changed in size, position, or reflectional orientation between the first and second presentations of the faces. In contrast, subjects were slower to recognize both faces and objects when they were planar-rotated between the first and second presentations. The results suggest that the same metric invariances are shown by both face recognition and basic-level object recognition.
