Teaching teenagers with autism to seek assistance when lost

Three teenagers with autism were taught to respond to a vibrating pager to seek assistance in community settings when physically separated from their parents or teachers. A multiple baseline probe design across participants demonstrated that, upon being paged, participants successfully handed a communication card to a community member indicating that they were lost. Generalization was assessed in nontraining community sites and on outings with the participants' parents.     

Multiple-group membership: warmth and competence perceptions in the workplace

What kinds of stereotypes are evoked when employers review a job application from a 55-year-old Arab woman? Most previous research on stereotypes has focused on single demographic group categories (e.g., race or gender) rather than on their combinations, even though people inevitably belong to multiple group categories simultaneously. The current study examines how different combinations of demographic group categories (ethnicity, gender, sexual orientation, and age) are perceived in the context of the workplace, with a focus on two fundamental dimensions of social perception: warmth and competence. The results reveal interesting interactions among the studied demographic group categories such that when stigmatized group categories are added to one another, it does not necessarily produce additive negative effects on warmth and competence perceptions. Rather, one category that is perceived negatively in isolation (e.g., homosexuality) can offset the negative impact of another stigmatized category (e.g., Arab ethnicity). Practical implications for stereotyping and discrimination in the workplace are discussed.

What Makes It Rape? A Lay Theories Approach to Defining Rape Among College Students

Recent changes in the U.S. Justice Department’s definition of rape have renewed its public attention. The present study applied a lay theories approach to the assessment of what college students currently think about rape. Participants (n?=?272) defined rape in their own words; responses were qualitatively analyzed and prominent themes identified. Major themes included the physicality of rape and the victim’s response; minor themes included the potential for victims to be physically harmed and rape’s gendered nature, among others. These findings provide insight into how this demographic conceptualizes and theorizes rape, which is an important step in reducing its prevalence.     

Illusory hand ownership in a patient with personal neglect for the upper limb,but no somatoparaphenia

The symptoms of patients with left personal neglect are characterized by inattention towards contralesional (left) body parts while at the same time explicitly ascertaining ownership for the neglected hemibody. It is currently unknown if personal neglect is associated with more subtle or implicit disturbances of own body perception and body ownership as measured with the rubber hand illusion. In this study, we report data from a patient with a right hemispheric lesion and personal neglect, without associated somatosensory deficits. We administered to the patient (and to 12 age‐matched controls) the rubber hand illusion paradigm to the right and left hands, to elicit illusory ownership for a fake hand, before and after recovery from personal neglect for the left arm. In a first session, run when the patient showed personal neglect affecting the left arm, he experienced a significantly enhanced subjective illusion of embodiment for the left fake hand as compared to the right hand (as assessed through a standard questionnaire). After recovery from personal neglect for the left arm (second session), the results of the left and right rubber hand illusion experiments were comparable, with no modulation of hand ownership. We argue that personal neglect may consist not only in an inattentional disorder, but also in a deficit of multisensory body representation characterized by a high sensitivity to experimental manipulations of subjective aspects of body ownership.     

The link between stress,well-being,and psychological flexibility during an Acceptance and Commitment Therapy self-help intervention

Background/Objective: Prolonged stress can overwhelm coping resources, leading people to seek mental health care. Acceptance and commitment therapy (ACT) is an intervention that enhances well-being and reduces distress, assumedly by means of increasing psychological flexibility (PF). We examined the association between a total increase in PF during an intervention and decreases in stress and increases in well-being during and after the intervention. Method: The intervention was a randomized controlled trial of an ACT-based self-help intervention. Participants were 91 individuals reporting elevated levels of work-related stress. Measurements were completed at preintervention, postintervention, and 3-month follow-up. Results: Structural equation models revealed that the total increase in PF during the intervention was negatively associated with a decrease in stress (b = -0.63, SE = 0.14, p < .001) and positively associated with an increase in well-being during the intervention (b = 0.48, SE = 0.11, p < .001), but not with a decrease in stress (b = 0.03, SE = 0.27, p > .05) and well-being (b = -0.04, SE = 0.39, p > .05) following the intervention. Conclusions: Our study provides empirical support for decreasing stress and promoting well-being through ACT and emphasizes the potential of PF in promoting well-being.     

Secondary attention-deficit/hyperactivity disorder following perinatal and childhood stroke: impact on cognitive and academic outcomes

This cross-sectional retrospective clinical research study examines a large group of children followed within a pediatric stroke program and a developmental attention-deficit/hyperactivity disorder (ADHD) clinic at the Hospital for Sick Children, between May 2004 and June 2016. All children with a history of stroke who participated in a neuropsychological assessment between the ages of 4 and 18 years were considered for inclusion. From a sample of 275 participants with a history of stroke, 36 children (13.1%) received a diagnosis of secondary ADHD. Children with secondary ADHD were younger at the time of stroke and more likely to be identified as having a presumed perinatal stroke and persistent seizures than children without secondary ADHD diagnoses. There were no differences in pattern of lesion, size, or laterality between children who developed secondary ADHD and those who did not. Children with secondary ADHD had the lowest scores across all cognitive and academic measures compared to children with stroke-only and developmental ADHD. Findings highlight the added risk of receiving a diagnosis of secondary ADHD following pediatric stroke. Implications for future research and directed intervention are discussed.     

A Biologically Plausible Action Selection System for Cognitive Architectures: Implications of Basal Ganglia Anatomy for Learning and Decision‐Making Models

Several attempts have been made previously to provide a biological grounding for cognitive architectures by relating their components to the computations of specific brain circuits. Often, the architecture's action selection system is identified with the basal ganglia. However, this identification overlooks one of the most important features of the basal ganglia—the existence of a direct and an indirect pathway that compete against each other. This characteristic has important consequences in decision‐making tasks, which are brought to light by Parkinson's disease as well as genetic differences in dopamine receptors. This paper shows that a standard model of action selection in a cognitive architecture (ACT‐R) cannot replicate any of these findings, details an alternative solution that reconciles action selection in the architecture with the physiology of the basal ganglia, and extends the domain of application of cognitive architectures. The implication of this solution for other architectures and existing models are discussed.
