Three experiments are reported, which are based upon the Wason four-card selection task inspection time paradigm, in which subjects solve computer-presented trials while using a mouse to indicate the card currently under consideration. Evans (1996) had shown that selected cards were inspected for longer than non-selected cards, and this was taken as support for the existence of pre-conscious heuristic processes that direct attention towards relevant aspects of a problem. However, Roberts (1998b) suggested that this inspection time effect is artefactual, due to task format induced biases. Experiment 1 utilized a "change" task: Cards were presented either as selected or not selected, and subjects changed these where necessary. This demonstrated an association between card selection and inspection time independently of one between the act of response and inspection time. Experiment 2 utilized a standard selection task, but subjects either responded within 2 s of each card presentation, or made selections with no time pressure. The curtailment of thinking time increased matching behaviour—more cards matching the terms in the rules were selected—and was replicated in Experiment 3 using a within-subjects design. Overall, the data support Evans' heuristic-analytic framework albeit with some caveats. 相似文献

This report describes ethnic and gender differences in suicide ideation among two large samples of middle school students in New Mexico (n = 2,140) and Texas (n = 1,302). Students completed a self-administered questionnaire on suicide ideation and psychosocial risk factors. Mexican Americans in both samples reported significantly higher prevalence of suicide ideation than did their European American counterparts. Mexican Americans were 1.8 times more likely to have high suicide ideation than European Americans. The suicide ideation risk for Mexican Americans remained unchanged in both samples after adjusting for gender, age, family structure, depression, low social support, and self-esteem. This study indicates that ethnicity plays an important role in suicidal ideation, but the mechanism remains unclear. 相似文献

This article explores associations between mothers’ trait verbal aggressiveness (VA) and maternal and child behavior during playtime interactions. Forty mothers completed a 10‐minute play period with one of their children (range = 3–8 years) and then responded to D. A. Infante and C. J. Wigley’s (1986) trait VA scale. Mothers’ trait VA was associated positively (r = .48) with their rate of directing and inversely (r =?.44) with their child’s rated cooperation. Qualitative analyses of a subset (n = 8) of interactions suggest that mothers high in trait VA used directives to control the choice, rate, and duration of activities, and used physical negative touch along with directives, more than low‐VA mothers. Behaviors associated with trait VA occur even during brief mother–child interactions in which triggers for aggressive behavior largely are absent. 相似文献

Available evidence, largely arecdotal suggests that students are turning to quick ways of making money such as work in the sex industry in order to balance their finances, a trend seen in other countries with similar student support and tuition fee policies. Further research is urgently needed to understand the scale of student involvement in sex work and to clarify our understanding of the factors that influence the decision to engage in it. Unfortunately a number of methodological, practical and political problems stand in the way of such research. These are discussed together with preliminary findings from an exploratory study.

Tested in a field experiment (N = 647) the hypothesis that perceptions of personal susceptibility are important in decisions to test one's home for radioactive radon gas. Experimental group subjects received a personal telephone call to tell them they lived in a high-risk area and a personal letter to reinforce the telephone message. After the intervention, experimental subjects were significantly more likely than minimal-treatment subjects to acknowledge the possibility of high radon levels in their homes. Perceptions of susceptibility and illness severity were significantly correlated with orders of radon test kits and with testing intentions. Nevertheless, there were no differences between groups in test orders or intentions. Results are discussed in terms of the difficulty of getting people to acknowledge susceptibility and the factors other than risk perceptions that influence self-protective behavior. 相似文献
