The effect of memory load on the right ear advantage in dichotic listening

The right ear advantage (REA) observed in dichotic tests was further investigated to examine the effects of memory load on the task. Memory load was operationally defined as the duration of time wherein subjects were asked to retain the stimuli, with no rehearsal, prior to recall. The delay periods interpolated between dichotic stimulation and recall were: no delay, 5, 10, and 15 sec delay. There was a significant REA in the no delay condition. The conditions with interpolated delay periods showed a substantial loss in overall accuracy, and at 15 sec delay showed a strong REA. The results offer suggestive evidence for a lateralized memory mechanism for storing speech sounds.     

Belief and credence: why the attitude-type matters

Philosophical Studies - In this paper, I argue that the relationship between belief and credence is a central question in epistemology. This is because the belief-credence relationship has...     

Examining Latino Family Participation in Treatment for Childhood ADHD: The Role of Parental Cultural Factors and Perceptions

Attention-deficit/hyperactivity disorder (ADHD) is a common mental health disorder in childhood. Unfortunately, Latino youth and their families are at increased risk of demonstrating poor treatment outcomes. The current study examined the impact of parental cultural factors and perceptions on Latino family participation in a psychosocial intervention for childhood ADHD. Sixty-one Latino youth and at least one of their primary parents and teachers participated in the current study. Results indicated that parental acculturation, attitudes regarding treatment, and baseline severity of child symptomatology and functional impairment were related to treatment participation outcomes. Implications and future directions are discussed.     

Social Norms and Egalitarian Values Mitigate Authoritarian Intolerance Toward Sexual Minorities

In the United States, acceptance of sexual minorities (e.g., gay men and lesbians) has increased substantially since the early 1990s. This study examined whether authoritarians' attitudes have been influenced by the societal shift toward greater acceptance of sexual minorities. Using data from the American National Election Studies (ANES) collected between 1992 and 2012, we tested a model in which authoritarianism, endorsement of egalitarian values, and social norms shifting in the direction of tolerance predict individual attitudes toward sexual minorities and LGBT rights issues. Results indicated that (1) there was a subset of authoritarians who endorsed egalitarian values, (2) authoritarians in general became more tolerant (i.e., held less negative attitudes) toward sexual minorities between 1992 and 2012, and (3) “egalitarian authoritarians” held more positive attitudes toward sexual minorities than other authoritarians. The findings contribute to contemporary theory and research on authoritarianism, which is moving from a monolithic view of authoritarianism to one in which culture and core values activate and shape manifestations of authoritarian tendencies.     

Are Individuals with Schizophrenia or Schizotypy More Creative? Evidence from Multiple Tests of Creative Potential

Schizophrenia and schizotypy have been often associated with above average creativity; however, empirical studies on the relationship between schizophrenia spectrum disorders and enhanced creativity generated inconsistent results. This research investigates if the association between schizophrenia spectrum disorders and creative potential levels is dependent upon which cognitive processes are examined during administered tests of creative potential. Our study examined 117 participants stratified into the following three subgroups: (a) 39 psychometrically determined low-schizotypal individuals, (b) 35 psychometrically determined high-schizotypal individuals, and (c) 43 patients with schizophrenia. Each participant completed 2 divergent thinking (DT) tasks, 2 convergent thinking (CT) tasks, and 2 creative tasks that combine both DT and CT processes. The data suggest that Group C had typical abilities in the DT, CT, and the combined creative thinking tasks; however, the group as a whole had intact originality during the Figural Completion (DT task) and the Tangram Construction (combined task). Notably, Group B showed significant advantages in both verbal and figural DT tasks. Group A and Group B demonstrated no significant differences in the creative thinking processes of CT; however, both groups outperformed Group C in these tasks.
