Genetic,Maternal, School,Intelligence, and Media Use Predictors of Adult Criminality: A Longitudinal Test of the Catalyst Model in Adolescence through Early Adulthood

The catalyst model suggests that adult criminality arises from the interaction of genetic and proximal social influences such as family influences, but that distal social influences such as media exposure have only negligible influence. This article uses data from a 13-year longitudinal study of adolescent health to examine the catalyst model. As expected by the catalyst model, adult criminality was best explained by a confluence of genetic and proximal social risk factors. The influence of media exposure on adult criminality was negligible. Implications of these findings for both theory and policy are discussed.     

Relating developments in children's counterfactual thinking and executive functions

The performance of 93 children aged 3 and 4 years on a battery of different counterfactual tasks was assessed. Three measures: short causal chains, location change counterfactual conditionals, and false syllogisms—but not a fourth, long causal chains—were correlated, even after controlling for age and receptive vocabulary. Children's performance on our counterfactual thinking measure was predicted by receptive vocabulary ability and inhibitory control. The role that domain general executive functions may play in 3- to 4-year olds' counterfactual thinking development is discussed.     

Inhibiting beliefs demands attention

Research across a variety of domains has found that people fail to evaluate statistical information in an atheoretical manner. Rather, people tend to evaluate statistical information in light of their pre-existing beliefs and experiences. The locus of these biases continues to be hotly debated. In two experiments we evaluate the degree to which reasoning when relevant beliefs are readily accessible (i.e., when reasoning with Belief-Laden content) versus when relevant beliefs are not available (i.e., when reasoning with Non-Belief-Laden content) differentially demands attentional resources. In Experiment 1 we found that reasoning with scenarios that contained Belief-Laden content required fewer attentional resources than reasoning with scenarios that contained Non-Belief-Laden content, as evidenced by smaller costs on a secondary memory load task for the former than the latter. This trend was reversed in Experiment 2 when participants were instructed to ignore their beliefs when reasoning with Belief-Laden and Non-Belief-Laden scenarios. These findings provide evidence that beliefs automatically influence reasoning, and attempting to ignore them comes with an attentional cost.     

A systematic review of research on religion and spirituality in the Journal of Traumatic Stress: 1990–1999

Surveys reveal that religion and spirituality are highly valuable to many people in times of crisis, trauma, and grief. The relationship between coping with trauma and the use of various spiritual beliefs is well established. The importance of clergy in trauma recovery is also well documented. A review of the 469 research and non-research articles published between 1990 and 1999 in the Journal of Traumatic Stress revealed that 8.7% (6/69) of non-research articles, 4.1% (15/366) of quantitative research articles and 2.9% (1/34) of qualitative research articles considered religion or spirituality in their work. Analysis of variance found a significant overall increase in the percentage of articles that mentioned religion/spirituality between the first half (1990–1994) and the second half (1995–1999) of the study period. The results are discussed in the context of the trauma research and in comparison to related disciplines. Recommendations for future research and clinical application are suggested for both traumatologists and religious scholars.     

Walking Speed and Global Cognition: Results from the OKLAHOMA Study

ABSTRACT

Executive functioning and processing speed have been related to physical functioning in non-demented, elderly samples; however, the relationship between walking speed and global cognition has not been examined. Six hundred and seventy-five community dwelling older adults were enrolled through their primary care physicians. Walking speed was assessed on a 50-foot course at usual pace. Global cognition was assessed with the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) Total Scale score. After adjusting for age, gender, and education, there was a strong inverse relationship between walking speed and global cognition, with slower walkers performing worse on the cognitive measures, faster walkers performing better on the cognitive measures, and the intermediate walkers performing in the middle. In these older adults, global cognition was related to walking speed.     

Rule Consequentialism and the Problem of Partial Acceptance

Most plausible moral theories must address problems of partial acceptance or partial compliance. The aim of this paper is to examine some proposed ways of dealing with partial acceptance problems as well as to introduce a new Rule Utilitarian suggestion. Here I survey three forms of Rule Utilitarianism, each of which represents a distinct approach to solving partial acceptance issues. I examine Fixed Rate, Variable Rate, and Optimum Rate Rule Utilitarianism, and argue that a new approach, Maximizing Expectation Rate Rule Utilitarianism, better solves partial acceptance problems.     

Effects of exposure to thin-ideal media images on body dissatisfaction: Testing the inclusion of a disclaimer versus warning label

The current study was designed to determine whether the inclusion of a disclaimer (i.e., “Retouched photograph aimed at changing a person's physical appearance.”) or warning (i.e., “Warning: Trying to look as thin as this model may be dangerous to your health.”) added to images of thin/attractive models would affect body dissatisfaction and intent to diet in female undergraduate students (n = 342). Participants were randomly assigned to one of four groups: (a) disclaimer, (b) warning, (c) model control, or (d) car control. Results revealed a significant interaction between group and time, whereby only the car control group reported a significant change (i.e., decrease) in body dissatisfaction over time. Groups did not differ on intent to diet measured at post-exposure. The results largely replicate other findings in this area and call into question advocacy efforts to label media images as a strategy to decrease women's identification with the stimuli.     

The representation of grammatical categories in the brain

Language relies on the rule-based combination of words with different grammatical properties, such as nouns and verbs. Yet most research on the problem of word retrieval has focused on the production of concrete nouns, leaving open a crucial question: how is knowledge about different grammatical categories represented in the brain, and what components of the language production system make use of it? Drawing on evidence from neuropsychology, electrophysiology and neuroimaging, we argue that information about a word's grammatical category might be represented independently of its meaning at the levels of word form and morphological computation.
