The Influence of Media Coverage on Responses to a Hypothetical Burglary Scenario1

The present study examined whether media coverage was likely to have an effect on burglars' emotional, cognitive, and behavioral responses to the offense. Questionnaires were distributed to 224 male students, who were asked to imagine that they had committed a “burglary under the influence of alcohol.” They were asked to express their thoughts, feelings, and possible actions, both before and after reading a newspaper article about the offense. A multidimensional scaling procedure identified 4 response themes: guilt, fear, forensic awareness, and pride. Two persuasion variables (inducing guilt and a hidden message) were found to have a multifaceted influence on the 4 themes. Implications for police use of the media as well as limitations of the study are discussed.     

Never on Sunny Days: Lessons from Weekly Attendance Counts

Congregational attendance data are abundant, accessible, and relevant for religious research. Weekly attendance histories provide information about worshippers, congregations, and denominations that surveys cannot capture. The histories yield novel measures of commitment, testable implications of rational choice theory, and compelling evidence that attendance responds strongly to changes in the opportunity cost of time.

A social neuroscience perspective on adolescent risk-taking

This article proposes a framework for theory and research on risk-taking that is informed by developmental neuroscience. Two fundamental questions motivate this review. First, why does risk-taking increase between childhood and adolescence? Second, why does risk-taking decline between adolescence and adulthood? Risk-taking increases between childhood and adolescence as a result of changes around the time of puberty in the brain’s socio-emotional system leading to increased reward-seeking, especially in the presence of peers, fueled mainly by a dramatic remodeling of the brain’s dopaminergic system. Risk-taking declines between adolescence and adulthood because of changes in the brain’s cognitive control system—changes which improve individuals’ capacity for self-regulation. These changes occur across adolescence and young adulthood and are seen in structural and functional changes within the prefrontal cortex and its connections to other brain regions. The differing timetables of these changes make mid-adolescence a time of heightened vulnerability to risky and reckless behavior.     

Young and older adults' strategies in complex arithmetic

Young and older adults solved complex addition problems such as 49 + 56. Verbal protocols, solution times, and percentage errors documented strategy repertoire and strategy selection in young and older participants and age-related differences in complex arithmetic performance. Both young and older adults used a set of 9 strategies to solve complex addition problems, although many older adults used a smaller strategy repertoire. The data also showed age-related differences in strategy execution and strategy selection. We discuss general implications of the present data to further our understanding of complex arithmetic and the role of strategic variations during aging.     

A facet analysis of police officers' self‐reported use of suspect‐interviewing strategies and their Discomfort with Ambiguity

This study sought to establish: (i) whether tactics in police suspects interviews can be represented by two interacting facets (cognitive/emotional and coercive/facilitative) and (ii) whether a preference for coercive combinations are positively associated with Discomfort with Ambiguity (Kruglanski, 1989 ). Ninety‐nine police interviewers from the Crime Wing Headquarters of the Hong Kong Police completed a self‐report survey of preferred suspect interviewing tactics, as well as Chiu, Morris, Hong, and Menon (2000) version of the Need For Closure scale. Smallest Space Analysis (Guttman, 1968 ) revealed a duplex structure of cognitive and affective coercive/facilitative themes. Moreover, self‐report results indicated that high scorers on Discomfort with Ambiguity were more willing to use a wider variety of tactics (including more coercive cognitive and emotional tactics) than low scorers (who were more prudent in their constraint and willingness to stick with facilitative cognitive and emotional tactics).

Decision making, movement planning and statistical decision theory

We discuss behavioral studies directed at understanding how probability information is represented in motor and economic tasks. By formulating the behavioral tasks in the language of statistical decision theory, we can compare performance in equivalent tasks in different domains. Subjects in traditional economic decision-making tasks often misrepresent the probability of rare events and typically fail to maximize expected gain. By contrast, subjects in mathematically equivalent movement tasks often choose movement strategies that come close to maximizing expected gain. We discuss the implications of these different outcomes, noting the evident differences between the source of uncertainty and how information about uncertainty is acquired in motor and economic tasks.     

Visuotactile apparent motion

This article compares the properties of apparent motion between a light and a touch with apparent motion between either two lights or two touches. Visual and tactile stimulators were attached to the tips of the two index fingers that were held apart at different distances. Subjects rated the quality of apparent motion between each stimulus combination for a range of stimulus onset asynchronies (SOAs). Subjects reported perceiving apparent motion between all three stimulus combinations. For light—light visual apparent motion, the preferred SOA and the direction threshold SOAs increased as the distance between the stimuli increased (consistent with Korte’s third law of apparent motion). Touch—touch apparent motion also obeyed Korte’s third law, but over a smaller range of distances, showing that proprioceptive information concerning the position of the fingers is integrated into the tactile motion system. The threshold and preferred SOAs for visuotactile apparent motion did not vary with distance, suggesting a different mechanism for multimodal apparent motion.
