Periods of 24 to 48 hours of food deprivation reliably induced pup-killing in 30–50% of non-killer male mice. The behavior was prevented by previous experience with young and did not perseverate to non-deprived states. Castrated males and intact females also exhibited pup-killing following food deprivation, suggesting that the behavior is neither sexdependent nor related to the presence of testosterone. The findings are discussed in terms of their relationship to predatory behaviors and population dynamics. 相似文献

PAULO MARCHON 《The International journal of psycho-analysis》2006,87(1):63-81
The author examines several works of an intersubjectivist trend, as well as writings by Hanly, Cavell and Bion, defending many of the named psychoanalysts' viewpoints. These viewpoints are expressed in the search and the struggle for truth, recognizing, like Popper, that truth exists but that we cannot know with certainty whether and when we touch upon it, only that this endless effort merits a lifetime's work because it is the attempt at an encounter with ourselves‐the true encounter. The author explains the criticisms by Green of Jacobs, and defends the maintenance of ‘a certain possible neutrality’ (Eizirik). He poses some questions with regard to Ogden's ‘third subject’, considering it, among other aspects, from the supervisory point of view, which may demonstrate the existence of ‘a certain possible objectivity’ of the emotional confl ict. He develops some criticisms concerning silence as an interpretative action by Ogden, and summarizes two case histories. Both were unconsciously attempting to manipulate the analyst intensely‐one of them to get the analyst to intervene in his love life, and the other to interrupt acting out. 相似文献

Perceived teasing experiences in body dysmorphic disorder 总被引:1,自引:0,他引:1
Individuals with body dysmorphic disorder (BDD) are excessively concerned about imagined or slight defects in their appearance (e.g., asymmetrical facial features). Cognitive-behavioral models of BDD propose that several factors, including dysfunctional appearance-related beliefs and life experiences, such as teasing, contribute to the avoidance behaviors or rituals (e.g., mirror checking, grooming) characteristic of BDD. Previous research has demonstrated an association between perceived teasing and body dissatisfaction. In the current study, we examined whether individuals with BDD (n = 16) report to have been teased more often than do mentally healthy controls (n = 17). The group comprising individuals with BDD reported more appearance- and competency-related teasing than did control participants. This study provides preliminary evidence for the association between perceived teasing and BDD. 相似文献

This article presents an interpretation of autoshaping, and positive and negative automaintenance, based on a neural-network model. The model makes no distinction between operant and respondent learning mechanisms, and takes into account knowledge of hippocampal and dopaminergic systems. Four simulations were run, each one using an A-B-A design and four instances of feedfoward architectures. In A, networks received a positive contingency between inputs that simulated a conditioned stimulus (CS) and an input that simulated an unconditioned stimulus (US). Responding was simulated as an output activation that was neither elicited by nor required for the US. B was an omission-training procedure. Response directedness was defined as sensory feedback from responding, simulated as a dependence of other inputs on responding. In Simulation 1, the phenomena were simulated with a fully connected architecture and maximally intense response feedback. The other simulations used a partially connected architecture without competition between CS and response feedback. In Simulation 2, a maximally intense feedback resulted in substantial autoshaping and automaintenance. In Simulation 3, eliminating response feedback interfered substantially with autoshaping and automaintenance. In Simulation 4, intermediate autoshaping and automaintenance resulted from an intermediate response feedback. Implications for the operant-respondent distinction and the behavior-neuroscience relation are discussed. 相似文献

不规则几何图形识别的取样首视点研究 总被引:5,自引:0,他引:5
用实验方法对不规则几何图形的取样首视点进行研究。作业任务有认同与匹配二种,显示条件有良好与不良二种,显示方式有旋转与不旋转二种,绩效指标用反应时与错误指数二项。结果表明:首视点的分布是非均匀的,落在轮廓部位的概率最大,落在中央或某条特定边的概率极小。首视点分布的均匀度与作业难度有关,在作业难度较大的情况下,首视点分布趋于集中。多数情况下,首视点的置位对作业绩效的影响不大。 相似文献

Recent work using decontextualized economic games suggests that cooperation is a dynamic decision‐making process: Automatic responses typically support cooperation on average, while deliberation leads to increased selfishness. Here, we performed two studies examining how these temporal effects generalize to games with richer social context cues. Study 1 found that time pressure increased cooperation to a similar extent in games played with in‐group members and out‐group members. Study 2 found that time pressure increased cooperation to a similar extent in games described as competitions and games described as collaborations. These results show that previous positive effects of time pressure on cooperation are not unique to neutrally framed games devoid of social context and are not driven by implicit assumptions of shared group membership or cooperative norms. In doing so, our findings provide further insight into the cognitive underpinnings of cooperative decision making. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献
