An Examination of Historical Loss Thinking Frequency and Rumination on Suicide Ideation in American Indian Young Adults 下载免费PDF全文

No research has empirically investigated whether frequency of historical loss thinking is a potential risk factor for suicide ideation in American Indians. Results of this study demonstrated that the frequency of historical loss thinking was positively associated with brooding and reflection at a small magnitude, but was not directly related to suicide ideation. Bootstrapping analyses indicated small indirect effects of historical loss thinking frequency on suicide ideation through brooding and reflection individually, but only through brooding when analyzed in a parallel mediation model. These findings suggest that American Indians who more frequently engage in historical loss thinking may be susceptible to suicide ideation via an increase in ruminative tendencies, specifically brooding. 相似文献

The new-born baby' ability to detect similarities and differences between three-dimensional stimuli and their two-dimensional representations is investigated in three experiments, using both visual preference and habituation procedures. In Expt 1 new-borns strongly preferred (looked more at) complex objects to their photographs. This preference was found with monocular viewing, and suggests that motion parallax is a salient cue in the detection of the differences between the two- and three-dimensional stimuli. The results from Expt 2 support the view that, for the new-born, the differences between objects and their two-dimensional representations are more detectable or salient than their similarities. These conclusions were further supported by the results from the last experiment, using simpler stimuli, although the preference was for the two- rather than the three-dimensional stimuli. The results suggest that studies which use only two-dimensional stimuli may provide only limited information about the course of perceptual development, at least in the first few months from birth. 相似文献

Lie-telling and impulsivity levels peak during late childhood to early adolescence and have been suggested to be related. Heightened impulsivity may lead adolescents to lie in favor of short-term benefits without consideration for the potential consequences of deception. The present study assessed longitudinal relations between self-reported impulsivity and lie-telling frequency. Participants from a large-scale longitudinal study (N = 1148; Mage = 11.55, SD = 1.69, 9–15 years at Time 1) reported on their impulsivity (Barratt Impulsiveness Scale) and their frequency of lie-telling to parents, to teachers, to friends, and about cheating across two time points 1 year apart. Cross-lagged path analysis revealed greater impulsivity was associated with more frequent lie-telling to parents, friends, and teachers, and about cheating over time. Our findings demonstrate the role of impulsivity in the development of lie-telling behaviors.
Research Highlights
- Impulsivity predicts lying across time in multiple contexts (to parents, friends, teachers, and about cheating).
- Previous research has demonstrated the role of top-down influences on lie-telling, but the current study suggests that bottom-up processes are also influential.
