During deployment, soldiers face situations in which they are not only exposed to violence but also have to perpetrate it themselves. This study investigates the role of soldiers' levels of posttraumatic stress disorder (PTSD) symptoms and appetitive aggression, that is, a lust for violence, for their engaging in violence during deployment. Furthermore, factors during deployment influencing the level of PTSD symptoms and appetitive aggression after deployment were examined for a better comprehension of the maintenance of violence. Semi-structured interviews were conducted with 468 Burundian soldiers before and after a 1-year deployment to Somalia. To predict violent acts during deployment (perideployment) as well as appetitive aggression and PTSD symptom severity after deployment (postdeployment), structural equation modeling was utilized. Results showed that the number of violent acts perideployment was predicted by the level of appetitive aggression and by the severity of PTSD hyperarousal symptoms predeployment. In addition to its association with the predeployment level, appetitive aggression postdeployment was predicted by violent acts and trauma exposure perideployment as well as positively associated with unit support. PTSD symptom severity postdeployment was predicted by the severity of PTSD avoidance symptoms predeployment and trauma exposure perideployment, and negatively associated with unit support. This prospective study reveals the importance of appetitive aggression and PTSD hyperarousal symptoms for the engagement in violent acts during deployment, while simultaneously demonstrating how these phenomena may develop in mutually reinforcing cycles in a war setting. 相似文献

Walking in an environment of moving ground texture 总被引:1,自引:0,他引:1

The visual control of global body movements has mainly been studied in terms of the maintenance of balance. The present experiment examined the effect of moving visual surroundings on the speed of locomotion. A virtually boundless optical environment was generated by the projection of a dotted texture on the ground that was reflected on large vertical mirrors fixed along the walls of the room. Subjects' head velocity was recorded over a walking path of about 10 m along the projection surface. In the experimental sessions, the texture was animated and moved at different speeds in the same direction as the subject or in the opposite direction. In the control condition, the projected texture remained motionless and therefore appeared to pass by at the subjects' walking speed. The subjects' task was to maintain a constant walking speed as far as possible over the different conditions. Changes in walking speed give indications of how the processing of optical flow modulates locomotor activity. 相似文献

The Observer Video-Pro is a system for collecting, managing, analyzing, and presenting observational data. It integrates The Observer software with time code and multimedia hardware components. It extends the functionality of a conventional real-time event recording program in various ways. Observational data can be collected, reviewed, and edited with synchronized display of the corresponding video images. For optimal visual feedback during coding, one can display the video image in a window on the computer screen. Video playback from either a VCR or a digital media file can be controlled by the computer, allowing software-controlled jog, shuttle, and search functions. Besides a wide range of VCRs, The Observer Video-Pro supports all major digital video file formats. The software allows the user to summarize research findings in numerical, graphical, or multimedia format. One can create a time-event plot for a quick glance at the temporal structure of the observed process, or run specific analysis procedures and generate reports with statistics. An Event Summary function is available for exploratory and qualitative analysis. Video material can be summarized in a Video Play List, which allows on-screen summary presentations or the creation of highlight compilations on tape, CD, or other media. Video images can be captured and saved as disk files, for use as illustrations in documents, slides for presentations, and so forth. In this paper we describe the design and operation of the system, illustrated with a case study from research on Repetitive Strain Injury (RSI). 相似文献

A basic goal for individuals as they struggle to face normative developmental tasks across their life span is to determine how to make meaning of their experiences, real and vicarious. The authors describe a workshop that gave counselors and human service practitioners meaning‐making strategies that they could use in their personal and professional lives. 相似文献

Models are presented describing how bullying others and being bullied are related to proactive and reactive aggressiveness. This was investigated among 1801 pupils in Norwegian schools at the end of grade five and among 2083 pupils at the end of grade eight. Pupils in the two samples were approximately 11 and 14 years old, respectively. The procedure of structural equation modeling with latent variables was followed using LISREL 8.30 to estimate the parameters. Analyses were conducted for boys and girls separately at fifth and eighth grades. Support for the assumptions of factor solution and factorial invariance of the concepts across gender and age was obtained independently from estimating structural parameters. Both proactive and reactive aggressiveness were related to bullying others and to being bullied at Level 5. Among the older pupils, there was a strong relationship between proactive aggressiveness and bullying others, while reactive aggressiveness was much more weakly related to bullying others. Being bullied, on the other hand, was only weakly related to proactive and reactive aggressiveness among the older pupils. Age was therefore an important factor in determining how proactive and reactive aggressiveness were related to bullying. When pupil gender is concerned, power‐related proactive aggressiveness in predicting bullying was a more important factor for boys, while affiliation‐related proactive aggressiveness was a more powerful factor for girls.

The present study replicates and extends previous findings of a relation between anxiety level and the use of dream symbolism. Anxiety, assessed by self-reports over a ten-day period, was positively related to the use of sexual symbolism identified from dream reports obtained over the same period. The appearance of symbolic dreams, however, was not preceded by elevated levels of anxiety. A positive relation was uncovered between the measure of anxiety and a measure of manifest sexual content in the dreams. 相似文献
