非暴力视频游戏中竞争情境对玩家合作倾向和攻击倾向的影响

使用中性视频游戏和亲社会视频游戏，采用单次双人给予倾向困境任务和辣酱范式分别测量被试的合作倾向和攻击倾向，旨在探究竞争性视频游戏情境对玩家合作倾向和攻击倾向的影响。结果发现：（1）在对合作倾向的影响上，无论是玩中性视频游戏还是亲社会视频游戏，竞争情境相比单人情境均能显著降低玩家的合作倾向；（2）在对攻击倾向的影响上，玩中性视频游戏，竞争情境相比单人情境能显著提高玩家的攻击倾向；但玩亲社会视频游戏，竞争情境与单人情境对玩家攻击倾向的影响差异不显著。本研究表明，游戏情境是影响玩家行为倾向的重要因素之一，在非暴力视频游戏中竞争情境对玩家行为倾向会产生消极影响，亲社会视频游戏在一定程度上能抑制竞争情境的消极效应。     

And who thinks on the baby? Thoughts on the method of infant observation

Abstract

After the method of infant observation, as developed by Esther Bick, and its significance for psychoanalytic training have been outlined, the method is critically assessed. The suggestion is then made that infant observation should be supplemented by video-analytic infant observation. Finally, thoughts on modifications of the process of infant observation are presented.     

Internet Addiction Disorder: Internet Gaming Disorder in a Nonclinical Sample Of Moba And Mmorpg Videoplayers

This study concentrates on two kinds of video games, Massive Online Battle Arena and Massive Multiplayer Online Role Play Game, and examines the scores obtained by the subjects in the sample. Score analyses pointed out that they do not exceed the respective cutoff scores for each scale. The sample was divided into three clusters to differentiate three kinds of users: nonproblematic, problematic, and “addicted” players. The study highlights that the variable “video game typology” relates to some personality traits. Players who excessively use them tend to experience relatively more negative emotions (anxiety and depression), avoid socioemotional involvement, and report bizarre and culturally incongruent thoughts (accompanied by the respective behavioral displays).     

Searching in the sand: Protracted video deficit in U.S. preschoolers' spatial recall using a continuous search space

Young children exhibit a video deficit for spatial recall, learning less from on-screen than in-person demonstrations. Some theoretical accounts emphasize memory constraints (e.g., insufficient retrieval cues, competition between memory representations). Such accounts imply memory representations are graded, yet video deficit studies measuring spatial recall operationalize memory retrieval as dichotomous (success or failure). The current study tested a graded-representation account using a spatial recall task with a continuous search space (i.e., sandbox) rather than discrete locations. With this more sensitive task, a protracted video deficit for spatial recall was found in children 4–5 years old (n = 51). This may be due to weaker memory representations in the screen condition, evidenced by higher variability and greater perseverative bias. In general, perseverative bias decreased with repeated trials. The discussion considers how the results support a graded-representation account, potentially explaining why children might exhibit a video deficit in some tasks but not others.

Research Highlights

• The task used a continuous search space (sandbox), making it more difficult and sensitive than spatial recall tasks used in prior video deficit research.
• Spatial recall among 4- and 5-year-old children was more variable after watching hiding events on screen via live video feed than through a window.
• Children's spatial recall from screens was more susceptible to proactive interference, evidenced by more perseverative bias in an A-not-B design.
• The results demonstrate memory representations blend experiences that accumulate over time and explain why the video deficit may be protracted for more difficult tasks.

     

Social relations and presence of others predict bystander intervention: Evidence from violent incidents captured on CCTV

Are individuals willing to intervene in public violence? Half a century of research on the “bystander effect” suggests that the more bystanders present at an emergency, the less likely each of them is to provide help. However, recent meta-analytical evidence questions whether this effect generalizes to violent emergencies. Besides the number of bystanders present, an alternative line of research suggests that pre-existing social relations between bystanders and conflict participants are important for explaining whether bystanders provide help. The current paper offers a rare comparison of both factors—social relations and the number of bystanders present—as predictors of bystander intervention in real-life violent emergencies. We systematically observed the behavior of 764 bystanders across 81 violent incidents recorded by surveillance cameras in Copenhagen, Denmark. Bystanders were sampled with a case–control design, their behavior was observed and coded, and the probability of intervention was estimated with multilevel regression analyses. The results confirm our predicted association between social relations and intervention. However, rather than the expected reversed bystander effect, we found a classical bystander effect, as bystanders were less likely to intervene with increasing bystander presence. The effect of social relations on intervention was larger in magnitude than the effect of the number of bystanders. We assess these findings in light of recent discussions about the influence of group size and social relations in human helping. Further, we discuss the utility of video data for the assessment of real-life bystander behavior.     

The effect of action video game playing on sensorimotor learning: Evidence from a movement tracking task

Research on the impact of action video game playing has revealed performance advantages on a wide range of perceptual and cognitive tasks. It is not known, however, if playing such games confers similar advantages in sensorimotor learning. To address this issue, the present study used a manual motion-tracking task that allowed for a sensitive measure of both accuracy and improvement over time. When the target motion pattern was consistent over trials, gamers improved with a faster rate and eventually outperformed non-gamers. Performance between the two groups, however, did not differ initially. When the target motion was inconsistent, changing on every trial, results revealed no difference between gamers and non-gamers. Together, our findings suggest that video game playing confers no reliable benefit in sensorimotor control, but it does enhance sensorimotor learning, enabling superior performance in tasks with consistent and predictable structure.
