A new group-training procedure for habituation demonstrates that presynaptic glutamate release contributes to long-term memory in Caenorhabditis elegans

In the experiments reported here we have developed a new group-training protocol for assessing long-term memory for habituation in Caenorhabditis elegans. We have replicated all of the major findings of the original single-worm protocol using the new protocol: (1) distributed training produced long-term retention of training, massed training did not; (2) distributed training at long interstimulus intervals (ISIs) produced long-term retention, short ISIs did not; and (3) long-term memory for distributed training is protein synthesis-dependent as it could be blocked by heat shock during the inter-block interval. In addition, we have shown that long-term memory for habituation is graded, depending on the number of blocks of stimuli in training. The inter-block interval must be >40 min for long-term retention of training to occur. Finally, we have tested long-term memory for habituation training in a strain of worms with a mutation in a vesicular glutamate transporter in the sensory neurons that transduce tap (eat-4). The results from these eat-4 worms indicate that glutamate release from the sensory neurons has an important role in the formation of long-term memory for habituation.     

License to sin: Self‐licensing as a mechanism underlying hedonic consumption

Hedonic overconsumption is often considered to be caused by impulsive factors. The current paper investigates whether self‐licensing, relying on reasons to justify subsequent gratification, can also be included as a significant contributor to hedonic consumption. Two studies were conducted to investigate whether self‐licensing can account for an increase in hedonic consumption while ruling out impulsive factors such as resource depletion, negative affect, and visceral state as alternative explanations. A pilot study indicated that perceiving oneself as having invested greater effort and thus having a self‐licensing cue did not lead to a decline in self‐control capacity compared with not having a self‐licensing cue. The main study employed the same procedure and established that having a licensing cue did lead to increased snack intake while controlling for impulsive factors. Together, these studies support the notion that self‐licensing is a separate mechanism leading to hedonic gratification independent of impulsive factors.

Sex differences in impulsivity: a meta-analysis

Men are overrepresented in socially problematic behaviors, such as aggression and criminal behavior, which have been linked to impulsivity. Our review of impulsivity is organized around the tripartite theoretical distinction between reward hypersensitivity, punishment hyposensitivity, and inadequate effortful control. Drawing on evolutionary, criminological, developmental, and personality theories, we predicted that sex differences would be most pronounced in risky activities with men demonstrating greater sensation seeking, greater reward sensitivity, and lower punishment sensitivity. We predicted a small female advantage in effortful control. We analyzed 741 effect sizes from 277 studies, including psychometric and behavioral measures. Women were consistently more punishment sensitive (d = -0.33), but men did not show greater reward sensitivity (d = 0.01). Men showed significantly higher sensation seeking on questionnaire measures (d = 0.41) and on a behavioral risk-taking task (d = 0.36). Questionnaire measures of deficits in effortful control showed a very modest effect size in the male direction (d = 0.08). Sex differences were not found on delay discounting or executive function tasks. The results indicate a stronger sex difference in motivational rather than effortful or executive forms of behavior control. Specifically, they support evolutionary and biological theories of risk taking predicated on sex differences in punishment sensitivity. A clearer understanding of sex differences in impulsivity depends upon recognizing important distinctions between sensation seeking and impulsivity, between executive and effortful forms of control, and between impulsivity as a deficit and as a trait.     

Gender symmetry in intimate aggression: an effect of intimacy or target sex?

Men's greater use of direct aggression is not evident in studies of intimate partner aggression. In previous research, the effects of target sex and relationship intimacy have frequently been confounded. This study sought to examine these effects separately. One hundred and seventy-four participants (59 male and 115 female) read vignette scenarios in which they were provoked by a same-sex best friend, an opposite-sex best friend, and a partner. For each target, participants estimated their likely use of direct physical and verbal aggression as well as noninjurious forms of anger expression. Results showed that men lower their aggression in the context of an intimate partnership and that this is an effect of the target's sex. In contrast, women raise their aggression in the context of an intimate partnership and this is an effect of intimacy with the target. The use of noninjurious angry behavior did not vary between targets for either sex of the participant, which suggests that the effects of target are confined to behaviors which carry an intention to harm. Possible effects of social norms and oxytocin-mediated emotional disinhibition on intimate partner aggression are discussed.     

Confabulating reasons for behaving bad: The psychological consequences of unconsciously activated behaviour that violates one's standards

Numerous studies have been conducted to demonstrate that behaviours are frequently activated unconsciously. The present studies investigate the downstream psychological consequences of such unconscious behaviour activation, building on work on the explanatory vacuum and post‐priming misattribution. It was hypothesized that unconsciously activated behaviours trigger a negative affective response if the behaviour violates a personal standard and that this negative affect subsequently motivates people to confabulate a reason for the behaviour. Results provided evidence for this mediated moderation model. Study 1 showed that participants who were primed to act less prosocially indeed reported increased levels of negative affect and, as a result, were inclined to confabulate a reason for their behaviour. Study 2 replicated these findings in the domain of eating and provided evidence for the moderating role of personal standards as well as the entire mediated moderation model. These findings have relevant theoretical implications as they add to the modest number of studies that demonstrate that the effect of unconscious priming may extend well beyond performing the primed behaviour itself to influence subsequent affect and attribution processes.

Commonsense about Psychoanalysis by Rudolph Wittenberg

Obstacles are described that constrain or block the full implementation of Yalom's model of inpatient group psychotherapy. These obstacles include situational constraints that are imposed by the temporal, spatial, and organizational structures of many treatment settings, and attitudinal constraints that consist of therapist and patient resistances to the implications and demands of the model. Recommendations are provided that have proven useful for overcoming these obstacles. They address such issues as: (1) patient confusion with here-and-now focus, (2) tendencies toward therapist-centered interaction, (3) the apparent irrelevance of interactional groups for many patient presenting problems, (4) insufficient time to accomplish interactional goals, and (5) the inability of patients to engage in group processing.     

Creative thought in Artists

One hundred and eleven subjects, 14 and 15 years of age, were administered the Coopersmith Self-Esteem Inventory and two questionnaires, modified from Bienvenu's Adolescent Communication Inventory, eliciting adolescents’ perceptions of their communication with both parents. The 10 males and 10 females with the highest self-esteem scores, and the 10 males and 10 females with the lowest scores were identified to form two groups: the High Self-Esteem Group and the Low Self-Esteem Group. Parents of these students completed questionnaires concerning parent-adolescent communication and marital communication and adjustment.

The five hypotheses tested were strongly supported. Adolescents with low self-esteem viewed communication with their parents as less facilitative than did adolescents with high self-esteem. Parents of adolescents with low self-esteem perceived their communication with their spouses as less facilitative, and rated their marriages as less satisfying, than did parents in the High Self-Esteem Group. There was lack of congruence between the perceptions of adolescents with low self-esteem and those of their parents; both mothers and fathers in the Low Self-Esteem Group viewed parent-adolescent communication as more facilitative than did the adolescents themselves.     

perceived social competence and rape myth endorsement

Survey responses from 1,023 “john” are used to ascertain the explanatory power of perceived social competence for rape myth endorsement. Ordinary least squares regression was utilized to empirically test this hypothesis while controlling for client demographic characteristics. Perceived social competence, in addition to client race, was demonstrated to be a significant predictive factor of rape myth endorsement. Limitations of the present study and suggestions for methodological improvement are discussed.
