Electromyographic Analyses of Responses to Intergroup Threat

Two studies tested predictions from intergroup threat theory concerning emotional responses to intergroup threat. Study 1 employed threatening video clips of the 9/11/01 World Trade Center attacks. Study 2 employed video clips of a threatening “opponent” in a competition. Facial electromyography (EMG) was employed to capture emotion‐related muscle activity. As participants viewed videos in Study 1, they were instructed to consider Americans' reactions or their personal reactions. In Study 2, an “opponent” presented individually directed or group‐directed stereotype threat. Both studies provide support for the theory: Participants experiencing individual threats displayed greater EMG activity in muscles corresponding to inwardly directed emotions (fear), while participants experiencing group threats displayed greater EMG activity in muscles corresponding to outwardly directed emotions (anger).     

Separating automatic and intentional inhibitory mechanisms of attention in adults with attention-deficit/hyperactivity disorder

Researchers in the cognitive sciences recognize a fundamental distinction between automatic and intentional mechanisms of inhibitory control. The use of eye-tracking tasks to assess selective attention has led to a better understanding of this distinction in specific populations, such as children with attention-deficit/hyperactivity disorder (ADHD). This study examined automatic and intentional inhibitory control mechanisms in adults with ADHD using a saccadic interference task and a delayed ocular response task. Thirty adults with ADHD were evaluated against 27 comparison adults on measures of inhibitory control. The delayed ocular response task showed that adults with ADHD were less able than comparison adults to inhibit a reflexive saccade toward the sudden appearance of a stimulus in the periphery. However, saccadic interference task performance showed that the ADHD group did not differ significantly from the comparison group on a measure of automatic inhibitory control. These findings suggest a dissociation between automatic and intentional inhibitory deficits in adults with ADHD.     

A comparison of methods for teaching receptive labeling to children with autism spectrum disorders

Many early intervention curricular manuals recommend teaching auditory-visual conditional discriminations (i.e., receptive labeling) using the simple-conditional method in which component simple discriminations are taught in isolation and in the presence of a distracter stimulus before the learner is required to respond conditionally. Some have argued that this procedure might be susceptible to faulty stimulus control such as stimulus overselectivity (Green, 2001). Consequently, there has been a call for the use of alternative teaching procedures such as the conditional-only method, which involves conditional discrimination training from the onset of intervention. The purpose of the present study was to compare the simple-conditional and conditional-only methods for teaching receptive labeling to 3 young children diagnosed with autism spectrum disorders. The data indicated that the conditional-only method was a more reliable and efficient teaching procedure. In addition, several error patterns emerged during training using the simple-conditional method. The implications of the results with respect to current teaching practices in early intervention programs are discussed.     

Socialization of Social Anxiety in Adolescent Crowds

In this study, we looked at whether social anxiety is socialized, or influenced by peers’ social anxiety, more in some peer crowds than others. Adolescents in crowds with eye-catching appearances such as Goths and Punks (here termed Radical), were compared with three comparison groups. Using data from 796 adolescents (353 girls and 443 boys; M _age  = 13.36) at three timepoints, the results show that adolescents affiliating with the Radical crowd tended to select peers from the same crowd group. Being a member of a crowd in itself did not predict socialization of social anxiety, but adolescents in the Radical crowd were more influenced by their peers’ social anxiety than adolescents who did not affiliate with the Radical crowd group. The results suggest that through a bidirectional process, adolescents affiliating with Radical crowds may narrow their peer relationship ties in time, and in turn socialize each other’s social anxiety.     

Documenting changes in adult speakers' locus of causality during stuttering treatment using Origin and Pawn scaling

The concepts of locus of control and locus of causality are similar and refer to the degree to which a person perceives daily occurrences to be a consequence of his or her own behavior. Locus of control is considered to be a unidimensional construct indicating an inverse relationship between the polls of internality and externality. The locus of control is generally determined by using questionnaires with a limited number of items. Locus of causality is considered to be a two-dimensional construct where Origin and Pawn values, which are similar to internality and externality, respectively, are not necessarily inversely related. Locus of causality is determined by content analysis of freely spoken or written narratives. In the current study Origin and Pawn scores were obtained from twenty adults prior to and following a three-week intensive stuttering treatment program. Brief narratives written by the participants were analyzed to obtain Origin and Pawn values. These scores were compared with traditional measures of therapeutic outcome (Locus of Control, OASES, PSI, percentage of syllables stuttered). Results indicated statistically significant increases in pre- to post-treatment Origin scores (p = .001; Cohen's d = 1.44) and statistically significant decreases in pre- to post-treatment Pawn scores (p = .003; Cohen's d = 1.11). Origin and Pawn scores showed significant relationships with other measures of stuttering, indicating concurrent and construct validity. Origin and Pawn scaling procedures appear to provide a valid, sensitive, and nonreactive indicator of the speaker's locus of causality and ability to develop an autonomous and agentic lifestyle.Educational objectives: After reading this article, the readers will be able to: (1) distinguish between the concepts of locus of control and locus of causality, (2) describe the characteristics of individuals behaving as an Origin and a Pawn, (3) differentiate patterns of change for Origin and Pawn scores prior to and following treatment, and (4) describe the clinical advantages using Origin and Pawn scaling procedures for individuals who stutter.     

Finding Treasures: Is the Community of Philosophical Inquiry a Methodology?

Contrastive mental causation

Any theory of mind needs to explain mental causation. Kim’s (upward) exclusion argument concludes that non-reductive physicalism cannot meet this challenge. One classic reply is that mental properties capture the causally relevant level of generality, because they are insensitive to physical realization. However, this reply suggests downward exclusion (if mental properties are causally efficacious, their physical realizers are causally impotent), contrary to physicalism’s assumption of closure. This paper shows how non-reductive physicalists can solve this problem by introducing a contrastive account of causation with non-exhaustive contrasts. That view has independent justification, because it is also needed to solve other puzzles. On this theory, both a mental property and its physical realizer can cause the same physical effect without lapsing into any problematic overdetermination when they cause that effect in contrast with distinct foils. This contrastive solution has advantages over previous accounts of mental causation and is defended against objections.

     

Muslim Dilemmas in the Republic of Ireland: Anti-Extremism and Self-Regulation in the Context of Super-Diversity

Since the 1990s, a very small Muslim community in the Republic of Ireland has expanded rapidly and become increasingly diverse. For all that research has identified growing expressions of anti-Muslim racism, mainstream Irish political discourse and political responses to Ireland’s Muslim communities have not reflected the antipathy towards Islam that is identifiable in a number of other European countries. The response of the Irish state towards Muslims has been one of apparent neglect, benign and otherwise, whilst Muslims, for their part, appear to have lived unobtrusively. We examine the position of Muslims in Ireland through the lens of three issues that have been debated within Muslim communities in recent years: the alleged threat of terrorist activity within Muslim communities; calls for regulation of Muslim/Islamic activities; and a 2018 controversy relating to comments made by a leading Islamic figure in Ireland on the topic of female genital mutilation. Our analysis, framed by Steven Vertovec’s concept of super-diversity, emphasizes the need for policymakers to avoid presumptions of homogeneity.
