竞技运动中自我控制的逆效应

自我控制的逆效应是指在高压力下,在进行努力地自我控制的过程中产了与意愿相反的心理状态的现象。文章介绍了逆加工理论的双过程模型,评论了与竞技运动相关的动作控制、情绪控制、消极表象抑制、放松和集中注意的心理控制的逆加工效应研究,并指出竞技运动中自我控制的逆加工效应研究存在三方面的局限：缺乏生态学效度、心理控制的逆效应的测量不够客观和应对策略研究不足,未来的研究应该在这三个方面有所改进     

The neural basis of prolonged suppression of predatory attack. I. Naturally occurring physiological differences in the limbic systems of killer and non-killer cats

The epileptic excitability of the basolateral amygdala was found to correlate with differences in predatory and defensive predisposition of rat-killing cats and non-rat killers. The threshold for elicitation of afterdischarge (ADT) in the amygdalas of rat killers was higher than the ADTs of non-rat killers. Furthermore, non-rat killers with the lowest ADTs had the weakest attack tendencies and were most sensitive to a variety of environmental threats in addition to those posed by prey. These differences in excitability were not found in control areas lateral to the amygdala or in the ventral hippocampus. The possibility that ADT is a behaviorally relevant measure of a long-term predatory suppression function of the amygdala is discussed.

MANIPULATION OF POTENTIAL PUNISHMENT PARAMETERS IN THE TREATMENT OF SELF-INJURY1

The self-injurious behavior (SIB) of a blind, profoundly retarded male was observed within a field setting as multiple forms of punishment were applied. The effects of hair-tug punishment were first systematically examined, then hair-tug and electric shock punishment were administered in varing ratios (of punishment deliveries per SIB response) supplemented by continuous restraint contingencies and made contingent on recurrent antecedents of SIB cycles. Treatments were applied over six months of consecutive daily sessions ranging from 30 min to 8 hr duration. Posttreatment followup observations were taken 12, 24, and 34 months after treatment. Partial suppression was produced as a direct function of hair-tug punishment in the initial phase. A generally progressive decrement was produced on already lowered SIB rates with the succeeding components of the treatment package. Extended periods of total SIB suppression occurred as punishment was rendered contingent on antecedent components of each SIB response cycle. Followup observations of nearly 3 yr duration indicated total suppression generalized over all settings in which the subject functioned. The findings were related to the contrasting limits prevailing in most reports of punishment-based SIB suppression.     

RECREATING THE SCENE: AN EFFECTIVE WAY TO PROVIDE DELAYED PUNISHMENT FOR INAPPROPRIATE MOTOR BEHAVIOR

A mediated punishment procedure that involved recreating a behavioral sequence by guiding the subject through the behavior in the situation in which it occurred was used to suppress several severe problem behaviors in two developmentally delayed children. The mediational procedure was first used with a 4-year-old autistic boy for biting and then for foot stomping. Next the procedure was used for stealing and hoarding behavior with a multiply handicapped 17-year-old girl. Results indicated that the procedure was effective and produced relatively rapid results. One advantage of the procedure is that it provides an opportunity for trained personnel to apply restrictive procedures to low frequency behavior that occurs in their absence rather than relying on less qualified staff to implement the procedure immediately after the behavior occurs.     

Effects of d-amphetamine and pentobarbital under concurrent fixed-ratio schedules.

Pigeons were studied under a two-key concurrent fixed-ratio schedule of food presentation. During the first five sessions, the fixed-ratio requirements were 30 responses on one key (major key) and 120 responses on the other key (minor key): responding occurred almost exclusively on the major key. When the fixed-ratio requirements were then made equal at 30 responses on both keys, responding continued to predominate on the major key. The asymmetric distribution of responses persisted when the concurrent fixed-ratio fixed-ratio schedule was interrupted with periods during which the major key was associated with extinction while the other key remained associated with a fixed-ratio schedule. Additionally, in some subjects the fixed-ratio requirements were increased. These schedule modifications decreased the asymmetry in responding but did not eliminate it. d-Amphetamine decreased rates on both keys and slightly increased the asymmetric distribution of responses, while pentobarbital reversed the distribution of responses by increasing low rates and decreasing high rates. The pigeons maintained their original asymmetric distribution of responses during the 1 1/2-year-long study, despite schedule alterations and drug administrations.     

Opposite ERP effects for conscious and unconscious semantic processing under continuous flash suppression

We examined whether semantic processing occurs without awareness using continuous flash suppression (CFS). In two priming tasks, participants were required to judge whether a target was a word or a non-word, and to report whether the masked prime was visible. Experiment 1 manipulated the lexical congruency between the prime-target pairs and Experiment 2 manipulated their semantic relatedness. Despite the absence of behavioral priming effects (Experiment 1), the ERP results revealed that an N4 component was sensitive to the prime-target lexical congruency (Experiment 1) and semantic relatedness (Experiment 2) when the prime was rendered invisible under CFS. However, these results were reversed with respect to those that emerged when the stimuli were perceived consciously. Our findings suggest that some form of lexical and semantic processing can occur during CFS-induced unawareness, but are associated with different electrophysiological outcomes.     

Emotion Regulation and Empathy: Which Relation with Social Conduct?

A shared consensus among researchers deals with the positive association between the ability to effectively regulate and manage one's emotion and the engagement in empathic behavior and morally desirable actions. This study was designed to investigate how dispositional reliance on suppression and reappraisal differently impacted on the cognitive and affective components of empathy and on social conduct, distinguishing among prosocial, internalizing, and externalizing behaviors. Two hundred nineteen middle adolescents were enrolled and fulfilled self-reports assessing emotion regulation strategies, empathy, and social behaviors. The results suggest that there are important distinctions among the emotion regulation strategies and the components of empathy as they relate to one another and to prosocial behavior and problem conduct. Specifically, cognitive reappraisal was related to prosocial behavior through empathic concern. While internalizing behavior was associated with emotion regulation strategies, externalizing behavior was only related to perspective-taking ability. Delimitations and practical implications were discussed.     

Direct Perceptual Access to Other Minds

It is sometimes claimed that we perceive people’s mental states in their expressive features. This paper clarifies the claim by contrasting two possible readings, depending on whether expression is conceived relationally or non-relationally. A crucial difference between both readings is that only a non-relational conception of expression ensures direct access to other minds. The paper offers an argument for a non-relational conception of expression, and therefore for the view that we directly perceive people’s mental states in their expressive features.     

Addressing Weight Suppression to Improve Treatment Outcome for Bulimia Nervosa

Cognitive behavioral therapy (CBT) is regarded as the gold-standard treatment for bulimia nervosa (BN), yet despite impressive empirical support for its effectiveness, over 50% of patients fail to achieve abstinence from binge eating and purging by the end of treatment. One factor that may contribute to reduced efficacy rates in CBT is weight suppression (WS; the difference between a person's highest weight ever at their adult height and current weight). A growing body of research indicates that WS in patients with BN may have a clinically significant effect on symptomatology and prognosis. However, the current cognitive behavioral framework for BN does not explicitly acknowledge the role of WS in the onset or maintenance of BN symptoms and does not provide guidance for clinicians on how to address WS during treatment. The relationship between WS, biological pressure to regain lost weight, and the maintenance of BN symptoms suggest that current cognitive behavioral models of BN may be improved by considering the role of WS and exploring needed treatment modifications. Indeed, a reconceptualization of existing models may offer insight into potential strategies that can be used to reduce the susceptibility to treatment dropout, nonresponse, and relapse. It is therefore necessary to consider whether, and how, clinicians' consideration of WS during case conceptualization and treatment planning could serve to improve CBT outcomes. The current review explores ways in which high WS could contribute to poor CBT outcomes, provides preliminary clinical recommendations for incorporating WS into existing cognitive behavioral treatments based on extant data and clinical wisdom, and proposes suggestions for future research needed in this domain.
