The sound of the crowd: auditory information modulates the perceived emotion of a crowd based on bodily expressions

Although both auditory and visual information can influence the perceived emotion of an individual, how these modalities contribute to the perceived emotion of a crowd of characters was hitherto unknown. Here, we manipulated the ambiguity of the emotion of either a visual or auditory crowd of characters by varying the proportions of characters expressing one of two emotional states. Using an intersensory bias paradigm, unambiguous emotional information from an unattended modality was presented while participants determined the emotion of a crowd in an attended, but different, modality. We found that emotional information in an unattended modality can disambiguate the perceived emotion of a crowd. Moreover, the size of the crowd had little effect on these crossmodal influences. The role of audiovisual information appears to be similar in perceiving emotion from individuals or crowds. Our findings provide novel insights into the role of multisensory influences on the perception of social information from crowds of individuals.     

Participating From the Comfort of Your Living Room: Feasibility of a Group Videoconferencing Intervention to Reduce Distress in Parents of Children With a Serious Illness or Injury

ABSTRACT

This study explored the feasibility and potential effectiveness of a videoconferencing group intervention for parents of children with a life-threatening illness. Parent functioning was assessed at pre, post, and 6-month follow-up (N?=?13). Semistructured interviews explored parent experiences of the program and clinicians’ experiences were systematically recorded. Attendance was high (92%) and parents reported comfort with the online delivery. Quantitative data revealed significant reductions on three of the nine measures examined (parent guilt/worry; unresolved sorrow/anger; lack of psychological flexibility). Clinician data are described and highlights the skills and program modifications required to adapt to the videoconferencing modality. A randomized controlled trial is now underway.     

‘Everybody makes errors’: The intersection of De Morgan's Logic and Probability, 1837 – 1847

For Ivor Grattan-Guinness on the occasion of his retirement. The work of Augustus De Morgan on symbolic logic in the mid-nineteenth century is familiar to historians of logic and mathematics alike. What is less well known is his work on probability and, more specifically, the use of probabilistic ideas and methods in his logic. The majority of De Morgan's work on probability was undertaken around 1837?–?1838, with his earliest publications on logic appearing from 1839, a period which culminated with the publication of his Formal Logic in 1847. This article examines the overlap between his work on probability theory and logic during the earliest period of his interest in both.     

Assessment of cognition in an adolescent Indigenous population

The assessment of cognition in Indigenous populations is often complicated by cultural and language differences and unfamiliarity with the assessment process. Cognitive tasks are being developed that reduce the impact of these factors. These processes need to be evaluated in different cultural and ethnic groups to determine whether they are appropriate. Such an assessment was recently used in two studies of cognition of 237 Indigenous Australian adolescents (age: M = 16.06 ± 2.16 years). The tasks were completed appropriately, with response times and error rates increasing for difficult tasks. Duration and error rates decreased for the round‐based tasks, in line with performance in non‐Indigenous samples. There were no gender effects. Age associations occurred in some tasks, but significant correlations were only of a small magnitude. Although the battery appeared to be completed appropriately in this study, more work needs to be conducted examining the influence of demographic factors to ensure that control data can be most appropriately matched in future studies.     

Retention of a Time Pressure Heuristic in a Target Identification Task

S. Rice and D. Keller (2009) previously reported that participants who were put under time pressure tended to comply more with a diagnostic aid than participants who were not put under time pressure. The present study investigates whether or not learning the benefits of this time pressure heuristic carries over to a second session. Seventy-two New Mexico State University students performed a simulated target-detection task, assisted by a 95% reliable diagnostic aid. Participants were exposed to the following conditions, which were composed of two sessions: speeded–speeded, unspeeded–speeded, speeded–unspeeded, or unspeeded–unspeeded. Results showed that participants who completed the speeded condition for Session 1 performed just as well in the 2nd session regardless of whether or not they were put under time pressure. Participants found that complying with the aid was beneficial to overall performance and continued to comply in a 2nd session even when allowed more time to overrule the aid.     

Using Potential Performance Theory to Test Five Hypotheses About Meta-Attribution

The aim of this study was to compare the reaction times and errors of Spanish children with developmental dyslexia to the reaction times and errors of readers without dyslexia on a masked lexical decision task with identity or repetition priming. A priming paradigm was used to study the role of the lexical deficit in dyslexic children, manipulating the frequency and length of the words, with a short Stimulus Onset Asynchrony (SOA = 150 ms) and degraded stimuli. The sample consisted of 80 participants from 9 to 14 years old, divided equally into a group with a developmental dyslexia diagnosis and a control group without dyslexia. Results show that identity priming is higher in control children (133 ms) than in dyslexic children (55 ms). Thus, the “frequency” and “word length” variables are not the source or origin of this reduction in identity priming reaction times in children with developmental dyslexia compared to control children.     

Defending the Objective List Theory of Well‐Being

The objective list theory of well‐being holds that a plurality of basic objective goods directly benefit people. These can include goods such as loving relationships, meaningful knowledge, autonomy, achievement, and pleasure. The objective list theory is pluralistic (it does not identify an underlying feature shared by these goods) and objective (the basic goods benefit people independently of their reactive attitudes toward them). In this paper, I discuss the structure of this theory and show how it is supported by people's considered judgments. I then respond to three objections. First, I argue that there is no conceptual reason to favor a monistic theory of well‐being over a pluralistic one (such as the objective list theory). Second, I argue that states of affairs can benefit people even though they hold no positive reactive attitudes toward them. And, third, I argue that objective list theorists can identify a fairly‐determinate list of basic goods.     

A practical variation of a multiple-schedule procedure: brief schedule-correlated stimuli

Multiple schedules using continuous discriminative stimuli have been used to minimize children's disruptive requesting for teacher attention (e.g., colored floral leis; Tiger & Hanley, 2004; Tiger, Hanley, & Heal, 2006). The present study evaluated the effectiveness of, and children's preferences for, two multiple-schedule arrangements in which brief experimenter vocalizations served as discriminative stimuli. Results showed that brief signals were highly effective discriminative stimuli for 3 of the 4 children, and that all children preferred one or both variations of the multiple schedule to a control arrangement. For 1 child, highly discriminated responding was achieved only when continuous signals were introduced.
