Although secure firearm storage can prevent firearm injury and death, secure storage is relatively rare. This tendency may be driven in part by a perceived lack of utility for secure storage in preventing suicide and other gun violence-related outcomes.  相似文献

The processing of attribute information during preference‐based decision making is affected by both the valence of that information and its importance to the decision. Although these two factors have typically been examined separately, we propose that their effects on elaboration and encoding are often codependent. Results of four experiments demonstrate that the traditional negativity effect, whereby negative attribute information is processed more extensively than positive attribute information, obtains only for the subset of attributes perceived to be most important. Among other attributes, the negativity effect is reduced or even reversed (a positivity effect). Our findings suggest important qualifications to prevailing notions of selective information processing. Copyright © 2017 John Wiley & Sons, Ltd.  相似文献

Research has shown that goal setting leads to gains in memory performance and memory self-efficacy across adulthood when goals are set by experimenters and accompanied by positive feedback. However, self-set memory goals have had less consistent impact. This research extended past studies on aging and memory goals to examine the impact of self-set goals using anchors to guide goal selection. Two trials of name, text, and list recall were administered to younger and older adults, comparing goal and no-goal groups. After baseline, participants assigned to the goal group set personal goals for memory gain on a second, post-goal trial for each of the three tasks. Anchoring for goal-setting was used to encourage the selection of realistic, yet challenging goals. Younger and older participants set comparable goals. Only younger adults showed a motivational response (higher gains across trials for goals than no goals), even though older adults reported being just as committed to their personal goals. Older adults may have failed to show reliable goal-related gains because no positive feedback was offered or because they were unable to activate effective strategies for improved performance.  相似文献

This daily diary study examined relations between two distinct perfectionism dimensions and work-related cognitions experienced by employees during evening leisure time. Drawing from perseverative cognitive processing theory, we hypothesized that perfectionistic concerns would be related to work-related worry and rumination during post-work evenings. In contrast, we hypothesized that a theoretically more adaptive perfectionist dimension (perfectionistic strivings) would be associated with positively valenced self-reflections about work across consecutive evenings. A sample of 148 full-time workers completed an initial survey, which included a trait perfectionism measure, reported their work-related cognitions across four consecutive evenings of a working week, rated their sleep quality immediately upon awakening on each subsequent morning, and their daily levels of emotional exhaustion and work engagement at the end of each work day. Results showed that perfectionistic concerns were indirectly negatively associated with sleep quality and work day functioning via the tendency to worry and ruminate about work. In contrast, perfectionistic strivings were indirectly positively associated with work day engagement via the propensity to experience positive thoughts about work during evening leisure time. The theoretical and practical implications of these findings are discussed.  相似文献

Two studies examined the relationship between religious orthodoxy and the complexity of thinking about religious and nonreligious issues. In both studies, participants who were high or low in religious orthodoxy wrote a paragraph outlining their thoughts about a religious issue (life after death in Study 1; existence of God in Study 2) and/or a nonreligious issue (capital punishment in Study 1; free trade between Canada and the U.S. in Study 2). The results of both studies indicated that participants who were high in religious orthodoxy were less complex in their thinking about religious issues than those low in religious orthodoxy, but did not differ in the complexity of their thinking about nonreligious issues. These results do not support the notion that orthodoxly religious individuals are dispositionally inclined to think in simpler or more rigid ways overall, but they do suggest a tendency to think less complexly about religious issues.  相似文献

Two studies use a free recall task to track, moment by moment, cognitive repercussions of an upcoming performance. As in earlier research, subjects display impaired recall for events which immediately precede an anticipated public performance. This “next-in-line effect” occurs even if the “performance” consists of reading a word to oneself. However, subjects show no memory deficit if their performance is not anticipated, and they have generally poor recall if they know they will be performing—but not when. Distraction and amnesia accounts of these recall deficits are discussed. Ancillary findings illuminate the organization of memory in social settings.  相似文献

This qualitative study explored concept of self and its connection to resilience among 35 elderly Israeli men and women, who live in a war zone along the border with Gaza. The participants were asked to tell their life stories and to answer questions that dealt with hardships they have faced, including the security threat that characterizes the area. Analyses of the interviews revealed 13 overall themes. The major theme discussed in this article centers on the interviewees’ self concept of being ideological pioneers, who have a strong belonging to the settlements they created in the desert. We conclude that this self-concept relates to resilience among this population, in spite of the hardships they have faced on the personal, familial, communal and social-political levels.  相似文献

A detailed coding system was constructed to study the frequency and salience of aggression in TV programs broadcast on Finnish television. Salience of aggression was measured by the brutality index which consisted of ratings concerning the (1) program context, (2) seriousness, (3) justification, and (4) dramatization of aggressive acts. When compared to previous studies of TV-violence, the rate of aggression in Finnish TV was moderate with 3.5 aggressive acts per program hour. Only 14% of aggressive acts portrayed brutal aggression, which was mostly seen in fictional films and serials. A clear 9 pm watershed was not seen in Finland, since aggressive acts were distributed quite evenly during the TV time. Aggressiveness of a program was not related to its popularity among viewers. © 1993 Wiley-Liss, Inc. ©1993 Wiley-Liss, Inc.  相似文献
