Internet Use and Web Communication Networks,Sources of Social Support,and Forms of Suicidal and Nonsuicidal Self‐Injury Among Adolescents: Different Patterns Between Genders

The relationships of Internet use, web communication, and sources of social support with adolescent self‐injurious thoughts and behaviors (SITBs) in Taiwan were investigated. The study sample of 391 12 to 18‐year‐olds was selected from nine public high schools. Findings show that girls are more likely to have SITBs, except for suicide gestures. Web communication is a risk factor for SITBs in boys but not in girls. Family support is protective in both genders. Support from friends is protective and support from significant others was a risk factor for suicide plans in girls. Support from virtual social communities can have both positive and negative effects on adolescent SITBs, with different effects by gender.     

Deliberate Self‐Harm in Adolescents Aged 12–18: A Cross‐Sectional Survey of 18,104 Students

Little is known about accurate prevalence and associated factors of deliberate self‐harm (DSH) among adolescents in Asian countries. In this study, the prevalence and associated factors of DSH among adolescents in Japan were examined. Data were derived from a cross‐sectional survey using an anonymous self‐report questionnaire and enrolling 8,620 adolescents aged 12–15 and 9,484 aged 15–18. DSH in the previous 12 months was reported by 3.3% (95% CI, 2.9–3.7) of junior and 4.3% (3.9%–4.7%) of senior high school respondents. The prevalence was more than four times as high among girls as among boys for both age groups. DSH was further strongly associated with having suicidal thoughts, having depression/anxiety symptoms, and having used recreational drugs. These associated factors were similar for both sexes and for both older and younger teenagers. A substantial minority of adolescents present with DSH, even among those aged 12–15. The prevalence of DSH in Japan was in the lower ranges of those reported for Western countries. The identified associated factors were not dissimilar from those reported in the West.

Altruistic or selfish? Responses when safety is threatened depend on childhood socioeconomic status

Altruism is an effective method of coping with threats. This research explored the relationship between childhood socioeconomic status (SES) and altruism under different situations. The results of five studies provided reliable evidence that safety-threat conditions moderated the relationship between childhood SES and altruism. Individuals with higher childhood SES exhibited higher altruistic intentions (Studies 1 and 2) and behaviors (Study 3) when they were manipulated to imagine a safety threat scenario (Study 1), when viewing pictures of disasters (Study 2), and when they were manipulated to believe that their health was under threat (Study 3). However, their childhood SES had no significant impact on their altruistic intentions and behaviors in relatively safe environments (Studies 1–3). This effect was again tested in more realistic environmental conditions using a large-scale survey in Study 4. In Study 5, we explored the underlying mechanism behind the earlier findings (i.e., temporal discounting).     

Altering the rhythm of target and background talkers differentially affects speech understanding

Three experiments investigated listeners’ ability to use speech rhythm to attend selectively to a single target talker presented in multi-talker babble (Experiments 1 and 2) and in speech-shaped noise (Experiment 3). Participants listened to spoken sentences of the form “Ready [Call sign] go to [Color] [Number] now” and reported the Color and Number spoken by a target talker (cued by the Call sign “Baron”). Experiment 1 altered the natural rhythm of the target talker and background talkers for two-talker and six-talker backgrounds. Experiment 2 considered parametric rhythm alterations over a wider range, altering the rhythm of either the target or the background talkers. Experiments 1 and 2 revealed that altering the rhythm of the target talker, while keeping the rhythm of the background intact, reduced listeners’ ability to report the Color and Number spoken by the target talker. Conversely, altering the rhythm of the background talkers, while keeping the target rhythm intact, improved listeners ability to report the Color and Number spoken by the target talker. Experiment 3, which embedded the target talker in speech-shaped noise rather than multi-talker babble, similarly reduced recognition of the target sentence with increased alteration of the target rhythm. This pattern of results favors a dynamic-attending theory-based selective-entrainment hypothesis over a disparity-based segregation hypothesis and an increased salience hypothesis.

     

Problem Representation,Option Generation,and Poliheuristic Theory: An Experimental Analysis

Poliheuristic (PH) theory has received strong empirical support for its depiction of the option selection process: it explains how leaders evaluate, weigh, and ultimately choose among a set of policy options. But PH theory does not explain how this initial set of options is generated. Foreign policy problem representation (PR) research has shown that the way in which leaders mentally represent decision problems determines which options are generated for consideration. In this article, we develop a hybrid PR‐PH framework in which leaders’ problem representations drive an unconscious screening process that occurs prior to the conscious screening of PH stage 1. We test hypotheses drawn from this framework experimentally and find that key elements of PR (most notably, perceived threat) determine which options consciously occur to decision makers and which options are not generated during a simulated foreign policy crisis.     

工作记忆内容驱动完全无关刺激捕获注意

研究通过三个实验以检验工作记忆内容能否自动引导注意选择视场中与之匹配的任务完全无关刺激。实验一要求被试在工作记忆保持阶段完成一个视觉搜索任务，结果发现当搜索序列外的无关干扰刺激与工作记忆内容匹配时搜索绩效显著降低；实验二结果表明该干扰效应不能归因于自下而上的启动机制，因为对颜色刺激仅仅进行知觉辨认而没有工作记忆加工时并没有产生启动效应；实验三通过缩短搜索任务刺激的呈现时间以使得被试在完成搜索任务前没有足够时间眼跳至无关干扰刺激，结果发现了与实验一类似的干扰效应，说明在没有眼跳的情况下与工作记忆内容匹配的完全无关刺激可以捕获注意。这些结果表明保持在工作记忆中的信息表征可以自动引导注意选择视场中与之匹配的任务完全无关刺激，为基于工作记忆内容的注意捕获提供了新证据支持。
