An Analysis of the Highway Accidents Reported by 1,306 University Students

Two-point MMPI code distributions for a sample of 609 precollege students were compared with the code distributions of 701 precollege students obtained two years previously. The samples showed highly similar two-point code distributions. The same seven two-point code types occurred most frequently in both samples, and these same seven code types accounted for over 50% of the cases in both samples.

Further support was thus obtained for the hypothesis that Scale 5 is related more to IQ and/or education aspiration and/or socioeconomic status than years of education per se.. Also, the original base rate data on two-point code frequencies, including Scales 5 and 0, were replicated, providing reliable data on “normal” college males. Previous research of this nature with this population has typically omitted Scales 5 and 0.     

Manipulation of visual information does not change the accuracy of distance estimation during a blindfolded walking task

While humans rely on vision during navigation, they are also competent at navigating non-visually. However, non-visual navigation over large distances is not very accurate and can accumulate error. Currently, it is unclear whether this accumulation of error is due to the visual estimate of the distance or to the locomotor production of the distance. In a series of experiments, using a blindfolded walking test, we examine whether enhancing the visual estimate of the distance to a previously seen target, through environmental enrichment, visual imagery, or repeated exposure would improve the accuracy of blindfold navigation across different distances. We also attempt to decrease the visual estimate in order to see if the opposite effect would occur. Our results would indicate that manipulation of the static visual distance estimate did not change the navigation accuracy to any great extent. The only condition that improved accuracy was repeated exposure to the environment through practice. These results suggest that error observed during blindfold navigation may be due to the locomotor production of the distance, rather than the visual process.     

Mad enough to see the other side: Anger and the search for disconfirming information

The current research explored the effect of anger on hypothesis confirmation—the propensity to seek information that confirms rather than disconfirms one's opinion. We argued that the moving against action tendency associated with anger leads angry individuals to seek out more disconfirming information than sad individuals, attenuating the confirmation bias. We tested this hypothesis in two studies of experimentally primed anger and sadness on the selective exposure to hypothesis confirming and disconfirming information. In Study 1, participants in the angry condition were more likely to choose disconfirming information than those in the sad or neutral condition when given the opportunity to read more about a social debate, and reading the disconfirming information affected their subsequent attitude. Study 2 measured participants' opinions and information selection about the 2008 US Presidential Election and their desire to “move against” a person or object. Participants in the angry condition reported a greater tendency to oppose a person or object, which resulted in the attenuation of the confirmation bias.     

Retrospective recall of affect in clinically depressed individuals and controls

The current study examined the nature of retrospective recall of affect in depressed participants and nonclinical controls. Utilising the Experience Sampling Method, we compared average momentary affect reports to retrospective summaries of the same period of time. Both groups exhibited exaggerated retrospective summaries of positive affect (PA) and negative affect (NA). Greater bias for PA than NA was found in the controls but not the depressed. Across groups, depressed individuals exhibited more absolute inaccuracy in their recall of NA but not PA. For depressed and nonclinical individuals, retrospective summaries of PA were better predicted by an average of all weekly momentary PA than a combination of the most intense (“peak”) PA and most recent (“end”) PA experiences. For nonclinical participants, retrospective NA was better predicted by an average of all weekly momentary NA. For depressed individuals, however, no clear advantage to predicting retrospective NA by average weekly NA relative to a combination of peak NA and end NA was found. Based on our findings, clinicians should realise that depressive cognition may not lie in recall that is less positive and more negative than “reality” but in retrospective intensifications of all affect that are, compared to normal, relatively greater for negative than for positive affect.     

Priming a natural or human-made environment directs attention to context-congruent threatening stimuli

Research suggests that attention is attracted to evolutionary threats (e.g., snakes) due to an evolved “fear-module” that automatically detects biological threats to survival. However, recent evidence indicates that non-evolutionary threats (e.g., guns) capture and hold attention as well, suggesting a more general “threat-relevance” mechanism that directs attentional resources toward any potential danger in the environment. The current research measured how selective attentional resources were influenced both by the type of threat (e.g., snake vs. gun) and by the context in which the threat was encountered. Participants were primed with either natural or human-made environments to assess how these contexts influence attention to evolutionary and non-evolutionary threats, as measured by a spatial-cueing task. The results indicate that whether biological or non-biological threats receive greater attentional processing is determined by the context in which they are encountered.     

Improving Middle School Professional Development by Examining Middle School Teachers' Application of Literacy Strategies and Instructional Design

The goal of this article is to explore the effects of professional development on middle school teachers' understanding and application of literacy strategies supporting and enhancing instruction across the curriculum. This study investigated the extent to which reading and writing strategies, along with sound instructional design, were implemented by middle school teachers in their content areas based on data collected from self-reports (i.e., strategy and design checklists) and authors' classroom observations. Results from the analysis of the data collected suggest that the sampled middle school teachers used a wide variety of instructional strategies and instructional designs throughout their teaching. While certain instructional designs (whole-class discussion) and strategies (note-taking and graphic organizers) were used universally throughout the school, perhaps more important was the fact that others were selected dependent upon the unique content area they taught.     

Sexism as a Predictor of Attitudes Toward Women in the Military and in Combat

This study examined four forms of sexist beliefs as predictors of attitudes toward women in the military and in combat. Survey data revealed that military-affiliated college students (n = 62) held more negative attitudes than civilian students (n = 254) toward women in combat, but the groups did not differ on attitudes toward women in the military. All forms of sexism contributed uniquely to the prediction of attitudes toward women in the military, and 3 forms were associated with approval of women in combat. Sexist beliefs mediated the relationship between military-affiliation status and approval of women in combat.     

Effect of Mg content on Portevin–Le Chatelier band strain in Al–Mg sheet alloys

Experimental measurements of stress drops and band strains in type-B Portevin–Le Chatelier (PLC) bands were carried out for 5xxx series Al–Mg sheets with Mg content between 1.8 and 4.5?wt%. While the stress drops increase with global strain, the band strain values in all the samples follow a common linear relationship with global strain. The results indicate that the type-B PLC band strain is independent of solute content at given strain rate.
