安全依恋启动影响社会行为：方法、效果与机制

阈上或者阈下的安全依恋启动可以使个体获得暂时的依恋安全感,并对个体的社会行为产生显著的影响。这种影响主要表现在个体会表现出更多的亲社会行为、揭露行为以及更少的欺骗、歧视行为和道德脱离行为。这可能是因为启动激活的依恋安全感迁移至外显行为。脑神经活动是迁移顺利发生的生理基础。今后的研究可以设置更具生态效度的实验条件,以其它社会行为为研究对象,或者结合当前研究提出的迁移视角,进一步探索安全依恋启动对社会行为的影响。     

Well-being in major depression and social phobia with and without comorbidity

Background/Objective: Lower levels in well-being have been observed in individuals with Major Depression (MDD) and Social Phobia (SP), but well-planned direct comparisons with control individuals, not suffering from a mental disorder, are lacking. Furthermore, MDD is highly comorbid with anxiety disorders, and SP with depressive disorders. This study is among the first to examine differences in well-being in individuals with a clinical diagnosis of MDD or SP compared to individuals with no such diagnosis and to test differences in well-being within the combined diagnostic categories respective with and without anxiety-depressive comorbidity. Method: Participants were 119 individuals with a diagnosis of MDD, 47 SP and 118 controls. Results: Results revealed that overall well-being as well as emotional, psychological, and social well-being were lower in the MDD and SP group compared to the control group. Individuals with comorbidity reported lower well-being than individuals without comorbidity. Conclusions: These findings have clinical implications as presence of comorbidity may require a different therapeutic approach than with no comorbidity.     

Empirical tests of philosophical intuitions

Experimental philosophy seeks to examine empirically various factual issues that, either explicitly or implicitly, lie at the foundations of philosophical positions. A study of this genre (Miller & Feltz, 2011) was critiqued. Questions about the study were raised and broader issues pertaining to the field of experimental philosophy were discussed.     

Plasticity associated with escalated operant ethanol self-administration during acute withdrawal in ethanol-dependent rats requires intact matrix metalloproteinase systems

Repeated cycles of ethanol intoxication and withdrawal associated with dependence induce neuroadaptations in a variety of brain systems. Withdrawal-induced negative emotional states can be ameliorated by ethanol consumption; a learned process termed negative reinforcement. Accordingly, a dependence-induced phenotype is escalated ethanol self-administration. Matrix metalloproteinases (MMPs) are proteolytic enzymes which degrade the extracellular matrix to allow for synaptic reorganization and plasticity. To test the hypothesis that an intact MMP system is required for animals to learn about the negative reinforcing effects of ethanol and display escalated self-administration during acute withdrawal when ethanol-dependent, male Wistar rats were trained to self-administer ethanol and then assigned to either acute or chronic MMP inhibition treatment groups. The chronic treatment group received intracerebroventricular (ICV) infusions of the broad spectrum MMP inhibitor FN-439 or artificial cerebrospinal fluid (aCSF) via osmotic minipumps during a 1 month ethanol dependence induction period and subsequent post-dependence induction self-administration sessions that occurred during acute withdrawal. The acute treatment group only received ICV FN-439 or aCSF on the day of self-administration sessions following dependence induction during acute withdrawal. The results showed that inhibition of MMPs attenuated escalated ethanol self-administration following chronic and acute exposure conditions. Furthermore, once learning (i.e., plasticity) had occurred, MMP inhibition had no impact on escalated response patterns and animals previously subjected to MMP inhibition that did not escalate evidenced normal escalations in operant ethanol self-administration once FN-439 treatments were terminated. Thus, the present data identified that an intact MMP system is required for the escalated responding that occurs during acute withdrawal in dependent animals and implicate such escalation as a learned response.     

Antecedents and consequences of family social control use following an adolescent physical activity lapse

Objectives

This study explored the relationship between social control and behavior by examining both the antecedents of social control use following a physical activity lapse as well as the behavior reaction to the use of social control.

Design

As part of a larger project, high school students (N = 547) were prospectively followed over the course of a year and reported physical activity every two months.

Methods

For this study, 123 adolescents who reported experiencing a physical activity lapse sometime during the year were selected. Family physical activity and adolescent activity prior to the lapse were used to predict family use of social control tactics following the lapse. Use of social control tactics were used to differentiate whether adolescents increased their activity following the lapse or not.

Results

Results revealed that family physical activity predicted use of positive and collaborative social control following an adolescent activity lapse. Adolescent physical activity prior to the lapse also predicted parental use of collaborative social control following the lapse. In terms of the adolescent’s behavior reaction, an increase in collaborative social control following the lapse appeared to differentiate those who reported an increase in activity following the lapse compared with those who reported no increase.

Conclusions

This study provided support for physical activity behavior being both an antecedent and consequence of parental social control.     

震后青少年创伤后应激障碍与社会支持、人格的关系

采用问卷调查法对地震地区933名中学生进行调查,考察青少年创伤后应激障碍的状况,并探讨社会支持在人格与创伤后应激障碍之间的调节作用。结果表明：（1）震后六个月,约67.6%的青少年患有PTSD或部分PTSD。（2）大五人格特质中的神经质对事件影响量表总分以及唤醒、侵扰、逃避均有预测作用;宜人性对事件影响量表总分、侵扰、唤醒有预测作用。验证了社会支持在大五人格与逃避、人格与唤醒、人格与事件影响量表总分间调节效应显著的结论。

The associated nontargets effect: Evidence of nontarget processing at and beyond the level of letter recognition

In four visual search tasks participants were asked to make a target response if either of two targets was present and to make a nontarget response if neither target was present. Some target-absent displays included only nontarget stimuli or features that never occurred in the same displays as targets, whereas other target-absent displays included nontarget stimuli or features that did sometimes occur with targets. Nontarget responses were reliably faster in the former case than in the latter. This “associated nontargets effect” indicates that nontargets are not simply classified as nontargets but in addition are discriminated from one another. Current visual search models may underestimate the degree to which nontargets are processed during search.     

When attractiveness demands longer looks: The effects of situation and gender

We investigated how aesthetics guides our exploration of the environment. We embedded attractive and nonattractive faces into complex, real-world scenes and measured eye movements during scene viewing. We examined whether attractive faces would elicit longer looks, which would suggest that the aesthetic response orients people toward the rewarding and pleasing aspects of the environment. Experiment 1 showed that mean fixation, mean first fixation, and total fixation durations were longer to attractive faces, and fixations were longest to female faces and by female perceivers. In Experiment 2, we examined whether these effects of attractiveness are sensitive to situational factors. When perceivers were subjected to a threat or social approach manipulation prior to viewing the scenes, we confirmed specific hypotheses concerning the two manipulations. In accordance with the hypothesis that males have higher aggression potential than females, there were no differences in fixation durations between attractive and nonattractive male faces in the threat condition. On the other hand, in the social approach condition, both female and male attractive faces received longer looks. These results suggest that the aesthetic response orients people not only to the pleasing aspects of their environment, but also to those features that are adaptively relevant.     

Developmental changes in the control of saccadic eye movements in response to directional eye gaze and arrows

We investigated developmental differences in oculomotor control between 10-year-old children and adults using a central interference task. In this task, the colour of a fixation point instructed participants to saccade either to the left or to the right. These saccade directions were either congruent or incongruent with two types of distractor cue: either the direction of eye gaze of a centrally presented schematic face, or the direction of arrows. Children had greater difficulties inhibiting the distractor cues than did adults, which revealed itself in longer saccade latencies for saccades that were incongruent with the distractor cues as well as more errors on these incongruent trials than on congruent trials. Counter to our prediction, in terms of saccade latencies, both children and adults had greater difficulties inhibiting the arrow than the eye gaze distractors.
