Self-control in honeybees

Self-control means choosing a large delayed reward over a small immediate reward; impulsiveness is its opposite. The metabolic hypothesis states that the amount of self-control across species correlates negatively with metabolic rate (Tobin & Logue, 1994). Foraging honeybees have high metabolic rates; the metabolic hypothesis would predict little self-control in bees. But foraging bees work for the longterm good of their hive, conditions that seem to require self-control. In three experiments, we gave bees the choice between (1) a sweeter delayed reward and a less sweet immediate reward and (2) a large delayed reward and a small immediate reward. Bees showed much self-control, inconsistent with the metabolic hypothesis.     

Evolving judgments of terror risks: foresight, hindsight, and emotion

The authors examined the evolution of cognitive and emotional responses to terror risks for a nationally representative sample of Americans between late 2001 and late 2002. Respondents' risk judgments changed in ways consistent with their reported personal experiences. However, they did not recognize these changes, producing hindsight bias in memories for their judgments. An intensive debiasing procedure failed to restore a foresightful perspective. A fear-inducing manipulation increased risk estimates, whereas an anger-inducing manipulation reduced them-both in predictions (as previously observed) and in memories and judgments of past risks. Thus, priming emotions shaped not only perceptions of an abstract future but also perceptions of a concrete past. These results suggest how psychological research can help to ensure an informed public.     

Emotion-modulated performance and activity in left dorsolateral prefrontal cortex

Functional MRI (fMRI) was used to examine the relationship between processing of pleasant and unpleasant stimuli and activity in prefrontal cortex. Twenty volunteers identified the colors in which pleasant, neutral, and unpleasant words were printed. Pleasant words prompted more activity bilaterally in dorsolateral prefrontal cortex (DLPFC) than did unpleasant words. In addition, pleasant words prompted more activity in left than in right DLPFC. Response speed to pleasant words was correlated with DLPFC activity. These data directly link positive affect, enhanced performance, and prefrontal activity, providing some of the first fMRI evidence supporting models of emotional valence and frontal brain asymmetry based on electroencephalography (EEG).     

Standard posture,postural mirroring and client-perceived rapport

The relationship between client-perceived rapport (as measured from a standardized client) and physical mirroring and the standard counsellor posture was investigated with interviews performed by 59 post-graduate students in counselling psychology. Videotaped recordings were used to code counsellor posture in the categories of: total postural mirroring, mirroring of the hands and arms, mirroring of the legs, mirroring of the torso, and the frequency of the standard counsellor posture across each minute of the interviews. These minutes were classified as 'high' in rapport or 'low' in rapport as measured by the standardized client. Results indicated that there was significantly more postural mirroring of the torso during high versus low minutes, but that the counsellor standard posture occurred significantly more frequently during low rapport minutes than in high rapport minutes. However, when examined over the entire length of the interviews, these data were able to be understood in terms of counsellor 'flexibility' of response rather than simply whether these postural behaviours were present or not. Implications for counsellor training are discussed.     

‘Too busy’? Father's attendance for family appointments

Fathers are often less likely to attend for appointments with their referred children at family and child psychiatry clinics than are mothers. The literature related to this topic is examined. A study of fathers' attendance at family sessions is reported, in which attenders are compared to non-attenders. It is concluded that conventional suppositions regarding fathers' attendance, such as work hours and family roles, are not as important predictors of fathers' attendance as fathers' relationships with their own fathers and current relationships with their partners. Clinical implications are examined.     

What Predicts Adolescent Violence in Better-Off Neighborhoods?

Predictors of repeated violent delinquency across ages 13–19 were investigated in a longitudinal sample of 420 urban adolescent males living in high- compared to low-socioeconomic status (SES) neighborhoods. Adolescents in high-SES neighborhoods were significantly less likely than their counterparts in low-SES neighborhoods to engage in serious and violent delinquency. Results indicated that risk factors for later repeated violence among adolescents in high-SES neighborhoods, such as physical aggression, may be biologically based, whereas risk factors for later violence among adolescents in low-SES neighborhoods, such as poor parent–adolescent communication and early intercourse, appeared to be context-dependent. Having positive attitudes toward problem behavior and delinquent peers increased risk for later violence regardless of neighborhood SES type. Theoretical and practical implications of the findings are discussed.     

Existential Group Therapy and Death Anxiety

Existential therapy in groups for older adults can help to provide life meaning; to facilitate social support; and to improve coping with grief, loss, chronic illness, and ultimately death. A scenario is presented that provides a clinical illustration of the use of existentialism in groups with older adults.     

DECREASING CHILDREN'S RISK TAKING ON THE PLAYGROUND

Playground mishaps are some of the most common sources of injury and are the leading killer of children. The present study used a multiple baseline design across three classrooms (N = 379 children). With minimal teaching and rewards, children decreased and maintained decreased risky playground behaviors on slides. Floor effects on climbers prevented the demonstration of similar effects. The decreases seen in risky slide behavior are discussed within the context of preventive safety training for playground injuries.
