Jamaican child-rearing practices: the role of corporal punishment

The family is the most prominent social group that exists. It prepares its members for the various roles they will perform in society. Yet, the literature has unequivocally singled out the family as the most violent social group, with parental violence against children being the most prevalent type of family violence. While societies like the United States, Japan, and Sweden have taken a hard line on physical punishment and shifted to a gentler approach to discipline, harsh disciplining of children persists elsewhere. In the Caribbean, and Jamaica in particular, child-rearing and disciplinary practices that would warrant child abuse charges in other Western societies are rampant. This article examines the child-rearing techniques of Jamaican adults and their assumed effects on child outcomes. It also examines the plausibility of the assumption that the harsh physical punishment meted out to children is partially responsible for the current social problems of that island nation. We recommend approaches to tackle the broad goals of addressing familial and societal practices that compromise children's development and well-being.     

The natural appearance of unnatural incline speed

In three experiments, college students provided judgments about a marble's speed along a nonlinear incline. Each experiment revealed widespread support for the slope-speed belief, a mistaken belief holding that an object's speed at any point depends on the slope at that point. In truth, an object's incline speed varies with its elevation. In Experiment 1, participants relied solely on a diagram. In Experiments 2 and 3, participants observed computer animations depicting the descent of a marble at speeds conforming to either the slope-speed belief or Newtonian theory, and they rated the slope-speed version as more "natural" than the correct version. The task in Experiment 1 gauged participants' consciously available knowledge, but the perceptual realism of the slope-speed animations suggests that the slope-speed belief is also held outside awareness. By contrast, virtually all previously identified false beliefs about motion appear unnatural once animated.     

Multidimensional Personality Questionnaire profiles of veterans with traumatic combat exposure: externalizing and internalizing subtypes

This study used the Multidimensional Personality Questionnaire (MPQ; A. Tellegen, in press) to identify personality-based subtypes of posttraumatic response. Cluster analyses of MPQs completed by combat veterans revealed subgroups that differed on measures relating to the externalization versus internalization of distress. The MPQ profile of the externalizing cluster was defined by low Constraint and Harmavoidance coupled with high Alienation and Aggression. Individuals in this cluster also had histories of delinquency and high rates of substance-related disorder. In comparison, the MPQ profile of the internalizing cluster was characterized by lower Positive Emotionality, Alienation, and Aggression and higher Constraint, and individuals in this cluster showed high rates of depressive disorder. These findings suggest that dispositions toward externalizing versus internalizing psychopathology may account for heterogeneity in the expression of posttraumatic responses, including patterns of comorbidity.     

When a reappearance is old news: visual marking survives occlusion

Performance in a visual search task becomes more efficient if half of the distractors are presented before the rest of the stimuli. This "preview benefit" may partly be due to inhibition of the old (previewed) items. The preview effect is abolished, however, if the old items offset briefly before reappearing (D. G. Watson & G. W. Humphreys, 1997). The authors examined whether this offset effect still occurred if the old items undergo occlusion. Results show that a preview benefit was found when the old items were occluded but not otherwise, consistent with the idea of top-down attentional inhibition being applied to the old items. The preview benefit is attenuated, however, by movement of the irrelevant stimuli in the displays.     

Adrenocortical reactivity and social competence in seven year-olds

We examined temporal changes in salivary cortisol in response to a peer self-presentation task in a group of seven year-olds, some of whom scored high, average, and low on the Harter, 1983 Perceived Social Competence Scale. Salivary cortisol was measured pre-task, and 20 and 35 min post-task. We found a significant relation between individual differences in perceived social competence and salivary cortisol reactivity in response to the task. Children who perceived themselves as socially competent exhibited a significantly greater decrease in salivary cortisol from 20 to 35 min following the task compared with children who self-reported a relatively lower degree of social competence. We speculate on the meaning of salivary cortisol changes in childrens socio-emotional development.     

The Search for Indigenous Psychologies: Data From Turkey and the Former USSR

On a analysé le contenu de 152 articles du Turkish Journal of Psychology et de 261 articles de la revue Soviet Psychology dans le but d'évaluer le degré d' «indigénisation>> des psychologies turque et soviétique. Il est apparu que la psychologie turque ne présentait aucune tendance à l'indigénisation vu que les théories et perspectives nord-américaines y étaient largement exploitées. Par contre, on a constaté que la psychologie soviétique était l'un des rares exemples de psychologie indigéne.
Articles in the Turkish Journal of Psychology (n = 152), and in the journal Soviet Psychology (n = 261) were content analysed to determine the degree of indigenisation in Turkish and Soviet psychology. The results indicated that there was no tendency towards indigenisation in Turkish psychology, and North American theories and perspectives were widely used. Soviet psychology was found to be one of the rare examples of an indigenous psychology.     

DISTINGUISHING BETWEEN EXTINCTION AND PUNISHMENT EFFECTS OF RESPONSE BLOCKING: A REPLICATION

Lerman and Iwata (1996) described a method for distinguishing between sensory extinction and punishment effects of response blocking on self-injurious behavior maintained independent of social contingencies. Results of their study suggested that blocking decreased the self-injurious hand mouthing of their participant via punishment. The current replication of these procedures with the self-injurious eye poking of a woman with developmental disabilities produced patterns of responding indicating that, for this participant, blocking functioned as an extinction procedure.
