Sustained attention to a predictable,unengaging Go/No-Go task shows ongoing development between 6 and 11 years

Response time variability (RTV) is a useful measure of sustained attention; however, little is known about developmental changes in RTV at different temporal frequencies. Thirty-five 6-year-olds, 31 8-year-olds, and 37 10-year-olds completed the fixed-sequence Sustained Attention to Response Task on three occasions, six months apart. Fast Fourier Transform and ex-Gaussian analyses of response time (RT) data assessed momentary fluctuations in RT, gradual changes in RT, and very long responses, thought to reflect attentional control fluctuations, slow-shifting arousal, and infrequent lapses in attention, respectively. A half-by-half analysis measured within-occasion time-on-task effects. The 10-to 11-year-olds performed with less momentary fluctuations in RT, fewer long responses, and fewer commission and omission errors than the younger groups. This group performed well in the first half of the task but showed time-on-task effects on measures of momentary fluctuations in RT, very long responses, target sensitivity (d’), and commission errors. The 6- to 7-year-olds performed less well than the older groups, and showed time-on-task effects, on almost all measures. The 8- to- 9-year-olds mostly performed at an intermediate level compared with the other groups; however, this group performed with a similar level of momentary fluctuations in RT and very long responses as the 6- to 7-year-olds. These findings indicate that there is ongoing maturation of various aspects of sustained attention on a predictable task, with a period of relative stability in performance between 8 and 9 years of age.     

The role of spatial frequency in emotional face classification

Previous studies with emotional face stimuli have revealed that our ability to identify different emotional states is dependent on the faces’ spatial frequency content. However, these studies typically only tested a limited number of emotional states. In the present study, we measured the consistency with which 24 different emotional states are classified when the faces are unfiltered, high-, or low-pass filtered, using a novel rating method that simultaneously measures perceived arousal (high to low) and valence (pleasant to unpleasant). The data reveal that consistent ratings are made for every emotional state independent of spatial frequency content. We conclude that emotional faces possess both high- and low-frequency information that can be relied on to facilitate classification.     

Ensemble coding remains accurate under object and spatial visual working memory load

A number of studies have provided evidence that the visual system statistically summarizes large amounts of information that would exceed the limitations of attention and working memory (ensemble coding). However the necessity of working memory resources for ensemble coding has not yet been tested directly. In the current study, we used a dual task design to test the effect of object and spatial visual working memory load on size averaging accuracy. In Experiment 1, we tested participants’ accuracy in comparing the mean size of two sets under various levels of object visual working memory load. Although the accuracy of average size judgments depended on the difference in mean size between the two sets, we found no effect of working memory load. In Experiment 2, we tested the same average size judgment while participants were under spatial visual working memory load, again finding no effect of load on averaging accuracy. Overall our results reveal that ensemble coding can proceed unimpeded and highly accurately under both object and spatial visual working memory load, providing further evidence that ensemble coding reflects a basic perceptual process distinct from that of individual object processing.     

Headphone screening to facilitate web-based auditory experiments

Psychophysical experiments conducted remotely over the internet permit data collection from large numbers of participants but sacrifice control over sound presentation and therefore are not widely employed in hearing research. To help standardize online sound presentation, we introduce a brief psychophysical test for determining whether online experiment participants are wearing headphones. Listeners judge which of three pure tones is quietest, with one of the tones presented 180° out of phase across the stereo channels. This task is intended to be easy over headphones but difficult over loudspeakers due to phase-cancellation. We validated the test in the lab by testing listeners known to be wearing headphones or listening over loudspeakers. The screening test was effective and efficient, discriminating between the two modes of listening with a small number of trials. When run online, a bimodal distribution of scores was obtained, suggesting that some participants performed the task over loudspeakers despite instructions to use headphones. The ability to detect and screen out these participants mitigates concerns over sound quality for online experiments, a first step toward opening auditory perceptual research to the possibilities afforded by crowdsourcing.     

Assessment of Psychopathic Traits in Singaporean Adolescents: Validation of the Antisocial Process Screening Device (APSD)

There is little knowledge available concerning psychopathic traits in Asian adolescents; a lack of a suitable measurement instrument for assessing psychopathy in Asian societies may account for this. This study aimed to validate a widely used scale in the West — the Antisocial Process Screening Device (APSD) — in Singaporean school-based and at-risk adolescents. Using an exploratory factor analysis (EFA) and a confirmatory factor analysis (CFA), this study examined the two-factor (i.e., grandiose-manipulative/impulsive traits and callous-unemotional traits) and three-factor (i.e., grandiose-manipulative traits, impulsivity, and callous-unemotional traits) models of the APSD in 1027 school-based and 113 at-risk adolescents. School samples are adolescents from three secondary schools, while at-risk samples are adolescents who manifest different types of delinquent behaviors and are either placed in more structured settings or need closer supervision although they have not violated the law. Gender invariance was further tested in the school-based sample by conducting a multigroup CFA. The convergent validity of the APSD was also investigated in the school-based sample. For the school-based adolescents, the APSD revealed that the three-factor model provided a superior fit over the two-factor model and the factorial invariance across gender. Significant relationships between the three dimensions of the APSD and aggression and delinquency support the convergent validity of the APSD. As for the at-risk adolescents, both the two- and three-factor models were acceptable, but the two-factor model was preferred as it was parsimonious and it aligned with the conceptualized characteristics of psychopathic traits. Findings suggest that the APSD is a reliable and sound instrument for measuring psychopathic traits in Asian school-based and at-risk adolescents.     

Assessment of Emotional Avoidance in Adolescents: Psychometric Properties of a New Multidimensional Measure

Emotional avoidance—which includes cognitive and attentional processes that function as means of avoiding or dampening emotional experiences—may be a transdiagnostic risk and maintenance factor for emotional disorders. However, existing measures generally assess separate aspects of emotional avoidance, and few multidimensional measures exist for adolescents. The aim of the current study was to establish the psychometric properties of a new multidimensional measure of emotional avoidance for adolescents--the Emotional Avoidance Strategy Inventory for Adolescents (EASI-A; Fairholme et al. 2008)--employing an exploratory structural equation modeling framework. Analyses yielded a three-factor structure for the EASI-A, including subscales measuring Avoidance of Emotion Expression, Avoidance of Thoughts and Feelings, and Distraction. Moderate correlations were observed between the EASI-A and a measure of thought suppression, and the EASI-A was significantly associated with anxiety and depression symptoms. The EASI-A is a new, psychometrically sound measure that will aid in the assessment of avoidance as a vulnerability factor for psychopathology and as an outcome and mechanism for treatments of emotional disorders in adolescents.     

Factor Structure of the Difficulties in Emotion Regulation Scale (DERS) in Adult Outpatients Receiving Dialectical Behavior Therapy (DBT)

The Difficulties in Emotion Regulation Scale (DERS; Gratz & Roemer in Journal of Psychopathology and Behavioral Assessment, 26, 41–54, 2004) is a widely used measure of emotion regulation, however, few studies have examined the scale’s psychometric properties in clinical samples. The current study examined the latent factor structure of the scale, in addition to other psychometric properties, in a naturalistic sample of adult outpatients (n = 344) receiving dialectical behavior therapy (DBT). A number of models were fitted, including a bifactor model, which has not previously been examined with the DERS, but which may be more appropriate for addressing the study’s two primary aims. These aims were to: (1) investigate some of the prior concerns raised about the Awareness subscale items; and (2) evaluate the appropriateness of using DERS total vs. subscale scores. Results indicated that a modified bifactor model which excluded the Awareness items from the general factor fit the data best. Additional findings suggested that the DERS total score (excluding Awareness items) was reliable and had good criterion-related validity in this sample. However, the findings related to the DERS subscales were mixed. This study extends prior research on the DERS by demonstrating the utility of the scale with individuals receiving DBT for problems with emotion regulation, as well as by clarifying some of the prior questions about the scale’s latent structure.     

Conflicts with Friends: A Multiplex View of Friendship and Conflict and Its Association with Performance in Teams

Drawing on conservation of resources theory, multiplex social networks research, and the emerging conflict involvement perspective, the purpose of this study is to develop and test a multiplex view of conflict that explicitly accounts for the nature of the social relationships between those involved in intrateam conflict and how these multiplex relationships differentially impact team performance. Data were collected from 120 teams engaged in a 4-month business simulation. Relationship conflicts occurring among team members who are friends have a negative impact on team performance, whereas those occurring between non-friends have a positive impact on team performance. Although we also find non-friend task conflicts to be beneficial for team performance, friend task conflicts have no impact on team performance. This study highlights the dark side of workplace friendships and admonishes managers to pay close attention not only to conflicts among employees, but also to the relational closeness of those involved in conflict. The current study provides empirical support for the emerging conflict involvement perspective by explicitly assessing the number of individuals involved in conflict as well as the type of relationships between them. We also extend research on multiplex relationships from the individual to the team level of analysis. Finally, we respond to calls for studies of multiplexity that include both positive and negative relationships.     

A Socioecological Approach to Relational Demography: How Relative Representation and Respectful Coworkers Affect Job Attitudes

Purpose

This paper advances a socioecological perspective toward understanding the relationship between demography and job attitudes by considering the joint effects of individual ethnicity and ethnic group relative representation—the degree to which an individual’s own demographic group is represented similarly in their organization and the community in which the organization is located.

Design/Methodology/Approach

Hierarchical polynomial regression analyses of census and survey data from 57,000 employees of 142 hospitals in the United Kingdom suggest that ethnic group relative representation is related to ethnic minority employees’ job satisfaction and turnover intentions.

Findings

An asymmetric pattern emerged wherein the effect of under-representation on turnover intentions was stronger than the effect of over-representation. Moreover, the effects of relative representation varied with respectful treatment by coworkers; relative representation had little effect on attitudes of employees who reported low levels of coworker respect but generally enhanced attitudes when respect was high.

Originality/Value

This work points to the meaningful role that socioecological factors can play in what are typically considered to be intraorganizational phenomena, thereby highlighting the need for organizational research to assess relevant aspects of the communities in which organizations are embedded.

     

Linking Workplace Aggression to Employee Well-Being and Work: The Moderating Role of Family-Supportive Supervisor Behaviors (FSSB)

Purpose

The present study examined the moderating effects of family-supportive supervisor behaviors (FSSB) on the relationship between two types of workplace aggression (i.e., patient-initiated physical aggression and coworker-initiated psychological aggression) and employee well-being and work outcomes.

Methodology

Data were obtained from a field sample of 417 healthcare workers in two psychiatric hospitals. Hypotheses were tested using moderated multiple regression analyses.

Findings

Psychiatric care providers’ perceptions of FSSB moderated the relationship between patient-initiated physical aggression and physical symptoms, exhaustion and cynicism. In addition, FSSB moderated the relationship between coworker-initiated psychological aggression and physical symptoms and turnover intentions.

Implications

Based on our findings, family-supportive supervision is a plausible boundary condition for the relationship between workplace aggression and well-being and work outcomes. This study suggests that, in addition to directly addressing aggression prevention and reduction, family-supportive supervision is a trainable resource that healthcare organizations should facilitate to improve employee work and well-being in settings with high workplace aggression.

Originality

This is the first study to examine the role of FSSB in influencing the relationship between two forms of workplace aggression: patient-initiated physical and coworker-initiated psychological aggression and employee outcomes.
