Vocational Personalities and Mindfulness

In the past few decades, many studies have been conducted on the positive effects of mindfulness, a state of openness to novelty in which an individual actively constructs categories and distinctions. The authors tested the applicability of Langer's ( 1989a ) mindfulness theory to Holland's ( 1997 ) vocational personalities. Data from 156 Israeli full‐time employees were collected. The results link different types of vocational personalities to a mindful mind‐set.     

The affect heuristic,mortality salience,and risk: Domain‐specific effects of a natural disaster on risk‐benefit perception

We examine how affect and accessible thoughts following a major natural disaster influence everyday risk perception. A survey was conducted in the months following the 2004 south Asian Tsunami in a representative sample of the Swedish population (N = 733). Respondents rated their experienced affect as well as the perceived risk and benefits of various everyday decision domains. Affect influenced risk and benefit perception in a way that could be predicted from both the affect‐congruency and affect heuristic literatures (increased risk perception and stronger risk‐benefit correlations). However, in some decision domains, self‐regulation goals primed by the natural disaster predicted risk and benefit ratings. Together, these results show that affect, accessible thoughts and motivational states influence perceptions of risks and benefits.     

Interpretation and Expectation in Childhood Anxiety Disorders: Age Effects and Social Specificity

Theory and treatment for childhood anxiety disorders typically implicates children’s negative cognitions, yet little is known about the characteristics of thinking styles of clinically anxious children. In particular, it is unclear whether differences in thinking styles between children with anxiety disorders and non-anxious children vary as a function of child age, whether particular cognitive distortions are associated with childhood anxiety disorders at different child ages, and whether cognitive content is disorder-specific. The current study addressed these questions among 120 7–12 year old children (53% female) who met diagnostic criteria for social anxiety disorder, other anxiety disorder, or who were not currently anxious. Contrary to expectations, threat interpretation was not inflated amongst anxious compared to non-anxious children at any age, although older (10–12 year old) anxious children did differ from non-anxious children on measures of perceived coping. The notion of cognitive-content specificity was not supported across the age-range. The findings challenge current treatment models of childhood anxiety, and suggest that a focus on changing anxious children’s cognitions is not warranted in mid-childhood, and in late childhood cognitive approaches may be better focussed on promoting children’s perceptions of control rather than challenging threat interpretations.     

The Goal Circuit Model: A Hierarchical Multi‐Route Model of the Acquisition and Control of Routine Sequential Action in Humans

Human control of action in routine situations involves a flexible interplay between (a) task‐dependent serial ordering constraints; (b) top‐down, or intentional, control processes; and (c) bottom‐up, or environmentally triggered, affordances. In addition, the interaction between these influences is modulated by learning mechanisms that, over time, appear to reduce the need for top‐down control processes while still allowing those processes to intervene at any point if necessary or if desired. We present a model of the acquisition and control of goal‐directed action that goes beyond existing models by operationalizing an interface between two putative systems—a routine and a non‐routine system—thereby demonstrating how explicitly represented goals can interact with the emergent task representations that develop through learning in the routine system. The gradual emergence of task representations offers an explanation for the transfer of control with experience from the non‐routine goal‐based system to the routine system. At the same time it allows action selection to be sensitive both to environmental triggers and to biasing from multiple levels within the goal system.     

The Probability of Guilt in Criminal Cases: Are People Aware of Being ‘Beyond Reasonable Doubt’?

Data from a series of studies presenting video recorded witness statements to laypersons and legal professionals were examined to trace the relationship between judged probability of guilt and the willingness to vote guilty or not guilty in hypothetical trials, in the absence of specific jury instructions. The results show that a majority of jury‐eligible young and elderly participants, and police officers, were willing to convict a defendant when the judged probability of guilt exceeded .6. This is considerably below the legally accepted standard of ‘beyond reasonable doubt’, which usually is equated with a very high, around .9 perceived certainty. When jury deliberations were allowed, the threshold for conviction rose, approaching the standard evinced by trial judges under the same conditions. The results suggest that people prefer to vote for guilt according to a balance of probabilities principle, considering only the individual case, and disregarding the implied frequencies of false convictions.

State-based versus reward-based motivation in younger and older adults

Recent decision-making work has focused on a distinction between a habitual, model-free neural system that is motivated toward actions that lead directly to reward and a more computationally demanding goal-directed, model-based system that is motivated toward actions that improve one’s future state. In this article, we examine how aging affects motivation toward reward-based versus state-based decision making. Participants performed tasks in which one type of option provided larger immediate rewards but the alternative type of option led to larger rewards on future trials, or improvements in state. We predicted that older adults would show a reduced preference for choices that led to improvements in state and a greater preference for choices that maximized immediate reward. We also predicted that fits from a hybrid reinforcement-learning model would indicate greater model-based strategy use in younger than in older adults. In line with these predictions, older adults selected the options that maximized reward more often than did younger adults in three of the four tasks, and modeling results suggested reduced model-based strategy use. In the task where older adults showed similar behavior to younger adults, our model-fitting results suggested that this was due to the utilization of a win-stay–lose-shift heuristic rather than a more complex model-based strategy. Additionally, within older adults, we found that model-based strategy use was positively correlated with memory measures from our neuropsychological test battery. We suggest that this shift from state-based to reward-based motivation may be due to age related declines in the neural structures needed for more computationally demanding model-based decision making.     

Associations between violence,criminality, and cognitive control deficits among young men living in low resource communities in South Africa

Despite empirical support for “Self-control theory” in criminology, there is controversy about how self-control should be operationalized. Working within the framework of “self-control theory,” we investigated if violence and criminal behaviors are associated with nine distinct dimensions of cognitive control in a community sample of young men (n = 654) living in peri-urban townships in South Africa. Cognitive control was assessed using the Behavior Rating Inventory of Executive Function. Multivariate statistical analysis was used, to identify associations between violence and criminality, and deaggregated measures of nine distinct components of cognitive control. Fifteen percent of the sample reported recent violence, 27% had been in physical fights with family/friends in the preceding 6 months, 10% reported being arrested, 4% reported forced sexual contact, and 26% reported intimate partner violence (IPV). Controlling for substance use and sociodemographic variables, contact with the criminal justice system and violence were associated with deficits in all domains of cognitive control. Forced sexual contact was associated with behavioral dysregulation. IPV was associated with behavior dysregulation and executive control dysfunction. Future studies might utilize deaggregated measures of self-control to provide further insight into links between particular components of cognitive control and various forms of offending and violence.
