Corporal punishment and child adjustment

The association between corporal punishment and children's emotional and behavioral functioning was studied in a sample of 98 non-referred children with a mean age of 12.35 (SD=1.72) recruited from two school systems in the southeastern United States. Children were divided into those who had experienced no corporal punishment over approximately a two-week period, those who had experienced mild levels of corporal punishment (i.e., 1 or 2 instances), and those who had experienced high levels of corporal punishment (i.e., 3 or more instances). Results indicated that use of corporal punishment was associated with problems in both emotional and behavioral adjustment. However, these associations were strongest for children who experienced high levels of corporal punishment, for children who were impulsive, and for children who did not experience a warm and supportive family climate.     

Body Satisfaction in Gym-active Males: An Exploration of Sexuality, Gender, and Narcissism

This study compared 80 gay and straight Australian males on self report measures of body satisfaction, masculinity, femininity, narcissism, and reasons for exercising at gyms to explore factors related to excessive exercise. Gay males are less satisfied with their bodies compared to straight males. Improving appearance was more important for gay men, while fun was considered more important for straight men. Only sexual orientation and masculinity contributed independently to body satisfaction. Straight males who scored high on masculinity were most satisfied with their bodies, while gay males who scored low on masculinity were least satisfied with their bodies, irrespective of femininity and narcissism. Hours exercising per week and fun as a reason for exercising, significantly contributed to body satisfaction.     

On Being Rejected: A Meta-Analysis of Experimental Research on Rejection

ABSTRACT— This article presents the first meta-analysis of experimental research on rejection, sampling 88 studies. The results are consistent with a needs account, which states that rejection frustrates basic psychological needs, but not with a numbness account, which states that rejection causes physical and emotional numbness. Rejection moderately lowers mood ( d =−0.50) and self-esteem ( d =−0.70), but does not decrease arousal or flatten affect. Both belonging ( d = 0.69) and control ( d = 1.16) are frustrated by rejection. Aggressive responses to rejection, considered paradoxical by some, appear to be due to attempts to gain control; measures that contrast belonging and control ( d =−1.17) cause antisocial responding, whereas measures that do not allow for control to be restored cause prosocial responding ( d = 1.21). These findings suggest that rejection makes individuals feel bad—ready to act to restore control or belonging—and that they will prioritize restoring control even if it requires being antisocial.     

Perceived threat and control as moderators of peace activism: Implications for mobilizing the public in the pursuit of disarmament

The present study was designed to investigate what variables discriminate individuals who actively work to promote disarmament from individuals who share the same attitudes but remain inactive. It is argued that if a person appraises nuclear war as an unlikely event, then it is not necessary to contemplate what can be done to prevent it. In contrast, if a threat is perceived, several possible coping strategies might be available, one of which is activism. However, activism is viable only if an individual believes that collectively the public can make a difference. Results of two surveys, one conducted with 142 peace activists across Canada and another with a random sample of 33 adults from the cities of Kitchener and Waterloo, Ontario, who are not active in the peace movement, confirm that perceptions of threat and belief in collective control are powerful discriminating variables. The implications of these findings for educating and mobilizing the public in the pursuit of disarmament are discussed.     

Humor response as related to violation of expectancies and to stimulus intensity in a weight-judgment task.

In a study of humor disguised as a psychophysical task, 60 subjects judged an initial series of 10 weights which was either light or heavy and then a shift weight which was either light, medium, or heavy. Degree of humorous response varied with the discrepancy of the shift weight and its absolute magnitude.     

S.I.M.P.L.E. control and measurement of auditory events

A SIMPLE interactive programming language is shown to be useful for psychological research involving auditory stimuli and responses. It is helpful in recording spoken stimulus tapes with program control of event sequencing and timing; it can control on-line interactive auditory and bisensory experiments; and it can calibrate the stimulus durations and pause times for auditory events.     

Psychosocial aspects of truancy in early adolescence.

The authors studied truancy in junior high school students, largely by structured interviews of 33 truants. Truancy at this age was commonly associated with significant difficulties at home, at school and with peers. Two modal types of truants were delineated: "authority defying" and "peer phobic." The school environment, including the response to truancy and the transition to the junior high, was found to play a critical role in creating and aggravating truancy. The authors discuss the findings with respect to strategies for prevention and remediation.     

Olfactory blocking and odorant similarity in the honeybee

Blocking occurs when previous training with a stimulus A reduces (blocks) subsequent learning about a stimulus B, when A and B are trained in compound. The question of whether blocking exists in olfactory conditioning of proboscis extension reflex (PER) in honeybees is under debate. The last published accounts on blocking in honeybees state that blocking occurs when odors A and B are similar (the "similarity hypothesis"). We have tested this hypothesis using four odors (1-octanol, 1-nonanol, eugenol, and limonene) chosen on the basis of their chemical and physiological similarity (experiment 1). We established a generalization matrix that measured perceptual similarity. Bees in the "block group" were first trained with an odor A and, in the second phase, with the mixture AB. Bees in the "novel group" (control group) were first trained with an odor N and, in the second phase, with the mixture AB. After conditioning, bees in both groups were tested for their response to B. We assayed all 24 possible combinations for the four odors standing for A, B, and N. We found blocking in four cases, augmentation in two cases, and no difference in 18 cases; odor similarity could not account for these results. We also repeated the experiments with those six odor combinations that gave rise to the similarity hypothesis (experiment 2: 1-hexanol, 1-octanol, geraniol) and found augmentation in one and no effect in five cases. Thus, blocking is not a consistent phenomenon, nor does it depend on odor similarity.     

A role for Synapsin in associative learning: the Drosophila larva as a study case

Synapsins are evolutionarily conserved, highly abundant vesicular phosphoproteins in presynaptic terminals. They are thought to regulate the recruitment of synaptic vesicles from the reserve pool to the readily-releasable pool, in particular when vesicle release is to be maintained at high spiking rates. As regulation of transmitter release is a prerequisite for synaptic plasticity, we use the fruit fly Drosophila to ask whether Synapsin has a role in behavioral plasticity as well; in fruit flies, Synapsin is encoded by a single gene (syn). We tackled this question for associative olfactory learning in larval Drosophila by using the deletion mutant syn^97CS, which had been backcrossed to the Canton-S wild-type strain (CS) for 13 generations. We provide a molecular account of the genomic status of syn^97CS by PCR and show the absence of gene product on Western blots and nerve-muscle preparations. We found that olfactory associative learning in syn^97CS larvae is reduced to ~50% of wild-type CS levels; however, responsiveness to the to-be-associated stimuli and motor performance in untrained animals are normal. In addition, we introduce two novel behavioral control procedures to test stimulus responsiveness and motor performance after “sham training.” Wild-type CS and syn^97CS perform indistinguishably also in these tests. Thus, larval Drosophila can be used as a case study for a role of Synapsin in associative learning.
