On the relation between theory of mind and executive functioning: A developmental cognitive neuroscience perspective

Theory of mind (ToM) and executive functioning (EF) show marked interrelatedness across childhood, and developmental psychologists have long been interested in understanding the nature of this association. The present review addresses this issue from a cognitive neuroscience perspective by exploring three hypotheses regarding their functional overlap: (1) ToM relies on EF (EF→ToM); (2) EF relies on ToM (ToM→EF); and (3) ToM and EF are mutually related, owing to shared neural structures or networks (ToM?EF). Drawing on evidence from normative brain development, neurodevelopmental and neurodegenerative diseases, patient lesion studies, and brain-imaging studies, we suggest that only a strict version of the ToM?EF proposal of complete neural overlap can be confidently ruled out on the basis of existing evidence. The balance of evidence suggests that separable neurobiological mechanisms likely underlie ToM and EF, with shared mechanisms for domain-general processing that support both abilities. We highlight how future studies may empirically substantiate the nature of the ToM–EF relationship using various biobehavioral approaches.     

Virtual Reality and Cognitive-Behavioral Therapy for Driving Anxiety and Aggression in Veterans: A Pilot Study

Within the U.S. military, motor vehicle accidents (MVAs) are the leading cause of preventable morbidity and mortality. Prior combat exposure and anxiety symptoms are associated with risky and aggressive driving, which is responsible for over half of MVA fatalities. Therefore, interventions are needed to reduce driving anxiety and aggression in veterans in order to mitigate the public health impact of MVAs. Virtual reality exposure therapy (VRET) offers safe, controlled exposure to distressing stimuli. The current study piloted a novel virtual reality and cognitive behavioral intervention (VRET + CBT) for veterans that integrated both anxiety and anger management components. Virtual reality driving scenarios were delivered in a driving simulator and tailored for the military population. Six previously deployed veterans completed eight intervention sessions, as well as pre/post, one month follow-up and six to nine month follow-up assessments. Repeated measures ANOVAs demonstrated significant decline and large effect sizes for PTSD symptoms, driving phobia, hyperarousal in driving situations, anxiety/anger-related thoughts and behaviors, and risky driving. Hyperarousal in driving situations declined by 69%, aggressive driving declined by 29%, and risky driving declined by 21%. Treatment gains were maintained at follow-up. Recruitment, retention, immersion, simulator sickness scores, and qualitative feedback demonstrated feasibility of the intervention. Implications for future research and adaptation are discussed.     

A Narrative Analysis of Sibling Grief

Sibling grief is linked to serious physical and mental health outcomes, yet remains the least researched of all family bereavement. This exploratory study created a shared sibling grief narrative. Open-ended interviews were conducted with 27 participants who lost a sibling. Primary themes included Shared Life: Identity Within the Sibling Arrangement; Sibling Death: Pivotal Moments in Time; Life After Sibling Loss: Emotional Suffering, Life After Sibling Loss: Missing Roles & Changing Relationships; and The Sibling Lives On. The following study findings clarify the overlooked impact that sibling death has on the surviving sibling and demonstrate the crucial need for more sibling loss research.     

Girls’ Perspectives of Barriers to Outdoor Physical Activity Through Photovoice: A Call for Counselor Advocacy

Physical inactivity and limited time spent in nature are major societal concerns that affect the mental and emotional health of youth in the United States. As such, this study explored girls’ perspectives of barriers to outdoor physical activity using a qualitative participatory action research method called photovoice. Six themes emerged from data representing the girls’ perspectives of barriers to outdoor physical activity through photovoice: Very Busy Schedule, Social Media, Health Concerns, Indoor Activity Instead of Outdoor Activity, Electronic Devices, and Way of Life. Researchers address how counselors can use these findings to advocate on this issue, given that counselors are called to advocate at multiple levels to address barriers that inhibit the growth and development of clients.     

Worry and rumination: do they prolong physiological and affective recovery from stress?

Background: Anxiety and depression have been linked to repetitive negative self-regulation styles in the form of worry and rumination respectively. Following predictions of the metacognitive model [Wells, A., & Matthews, G. (1994). Attention and emotion: A clinical perspective. Hove: Erlbaum], the current study compared the effect on recovery from stress of three strategies: worry, rumination, and distraction using a stress exposure paradigm. It was predicted that worry and/or rumination would be associated with delayed recovery on physiological and/or self-report indices when compared to distraction.

Method: Fifty-four participants were randomly assigned to one of the self-regulation conditions and then completed a modified version of the Trier Social Stress Test [TSST; Kirschbaum, C., Pirke, K. M., & Hellhammer, D. H. (1993). The “TSST” – A tool for investigating psychobiological stress responses in a laboratory setting. Neuropsychobiology, 28, 76–81. doi:10.1159/000119004]. Skin conductance and negative affect (NA) measurements were obtained at six different time points.

Results: Skin conductance indicated a prolonged recovery in the rumination condition when compared with the distraction condition. Individuals in the worry condition reported an immediate-delayed recovery from stress marked by higher NA scores in comparison to the distraction condition.

Conclusions: These findings may provide important insights into the effects of different forms of repetitive negative thinking on physiological and psychological recovery from stress. The different response patterns observed are discussed within the context of the metacognitive model.     

Disentangling Child-Specific and Family-Wide Processes Underlying Negative Mother-Child Transactions

The current study examines the transactional processes between maternal negativity and child disruptive behavior during early childhood, using a sibling comparison design. This design allows for a more sophisticated test of the behavioral training hypothesis than is possible when only one child per family is included in the analysis as it excludes two confounders (passive gene-environment correlation and family-wide environmental influence). Three hundred and ninety-seven families were visited on three occasions when the target child was 1.5, 3 and 4.5 years old (920 children, 51.5% female). The target child and up to three older siblings per family were included in data collection and analysis. Mothers and fathers reported on children’s disruptive behavior and mothers reported on their negativity to children. Within-family cross-lag pathways, as well as a significant indirect effect through which children increased their own disruptive behavior via maternal negativity confirmed a behavioral training effect. Family level maternal negativity and sibling disruptive behavior showed high levels of stability over three to four years and no context effect for maternal negativity or sibling disruptive behavior was seen. The theoretical and clinical implications of these findings are discussed.     

Non‐Bayesian Noun Generalization in 3‐ to 5‐Year‐Old Children: Probing the Role of Prior Knowledge in the Suspicious Coincidence Effect

It is unclear how children learn labels for multiple overlapping categories such as “Labrador,” “dog,” and “animal.” Xu and Tenenbaum (2007a) suggested that learners infer correct meanings with the help of Bayesian inference. They instantiated these claims in a Bayesian model, which they tested with preschoolers and adults. Here, we report data testing a developmental prediction of the Bayesian model—that more knowledge should lead to narrower category inferences when presented with multiple subordinate exemplars. Two experiments did not support this prediction. Children with more category knowledge showed broader generalization when presented with multiple subordinate exemplars, compared to less knowledgeable children and adults. This implies a U‐shaped developmental trend. The Bayesian model was not able to account for these data, even with inputs that reflected the similarity judgments of children. We discuss implications for the Bayesian model, including a combined Bayesian/morphological knowledge account that could explain the demonstrated U‐shaped trend.     

Comparing Data Sets: Implicit Summaries of the Statistical Properties of Number Sets

Comparing datasets, that is, sets of numbers in context, is a critical skill in higher order cognition. Although much is known about how people compare single numbers, little is known about how number sets are represented and compared. We investigated how subjects compared datasets that varied in their statistical properties, including ratio of means, coefficient of variation, and number of observations, by measuring eye fixations, accuracy, and confidence when assessing differences between number sets. Results indicated that participants implicitly create and compare approximate summary values that include information about mean and variance, with no evidence of explicit calculation. Accuracy and confidence increased, while the number of fixations decreased as sets became more distinct (i.e., as mean ratios increase and variance decreases), demonstrating that the statistical properties of datasets were highly related to comparisons. The discussion includes a model proposing how reasoners summarize and compare datasets within the architecture for approximate number representation.     

Perceptions of Nepotism Beneficiaries: The Hidden Price of Using a Family Connection to Obtain a Job

Purpose

This study tested competing predictions about the impact of nepotistic hiring on perceptions of nepotism beneficiaries, focusing specifically on the performance attributions made about nepotism hires. Of particular interest is how the qualifications of the family member compared to other applicants impacts perceptions of the nepotism hire.

Methodology

Two experimental studies, using scenarios that simulated the hiring process, were conducted. Participants reviewed materials describing the hiring process for a manager and then completed a questionnaire assessing their perceptions of the person hired.

Findings

Results showed that successful performance of nepotism beneficiaries was attributed more to political skills and relationships with upper management and less to ability and effort than was the case for non-beneficiaries and that they were perceived as less competent and as having fewer characteristics of successful managers. These negative perceptions occurred regardless of the family member’s qualifications.

Implications

This study contributes to our understanding of nepotistic hiring practices. More negative performance attributions and perceptions of competence for nepotism beneficiaries may hinder their effectiveness on the job. Knowledge gained from this study may help businesses who want to hire family members of current employees to manage this process more effectively.

Originality/Value

This is one of the first studies to examine the consequences of nepotistic hiring for nepotism beneficiaries and the first study to examine how nepotistic hiring effects the performance attributions made about nepotism beneficiaries. It is also the only study to empirically examine how the qualifications of the nepotism beneficiary influence others’ reactions to them.
