Impact of Trained versus Spontaneous Reciprocal Peer Tutoring on Adolescent Students

The purpose of this study was to compare the effectiveness of two different forms of reciprocal peer tutoring (RPT) on the motor and cognitive performance of adolescents in a physical education setting. We also explored the influence of gender. We assigned 72 ninth-graders (36 M, 36 F), all novices in a table tennis task, to a 2 × 3 (Gender × Learning Condition: physical practice with trained RPT [TRPT] vs. physical practice with spontaneous RPT [SRPT]vs. physical practice without any form of RPT [PP; individual control condition]) factorial design. Results indicated superior motor performance and cognitive skills for the TRPT condition and no difference between the SRPT and PP conditions. The peer-tutor training was thus a crucial organizational variable of the success of RPT. Interestingly, our results support the assumption that females particularly benefit from a highly structured peer tutoring framework.     

Facial Morphology and Children's Categorization of Facial Expressions of Emotions: A Comparison Between Asian and Caucasian Faces

The effects of Asian and Caucasian facial morphology were examined by having Canadian children categorize pictures of facial expressions of basic emotions. The pictures were selected from the Japanese and Caucasian Facial Expressions of Emotion set developed by D. Matsumoto and P. Ekman (1989). Sixty children between the ages of 5 and 10 years were presented with short stories and an array of facial expressions, and were asked to point to the expression that best depicted the specific emotion experienced by the characters. The results indicated that expressions of fear and surprise were better categorized from Asian faces, whereas expressions of disgust were better categorized from Caucasian faces. These differences originated in some specific confusions between expressions.     

Gambling: Relationship Between the Frequency of Wins and Irrational Thinking

In this study, we evaluated the relationship between the number of wins and the number of irrational verbalizations on the part of individuals playing American roulette. We predicted that subjects who win frequently would make more irrational verbalizations than rational verbalizations compared to subjects who win infrequently. Twenty Canadian subjects (8 men, 12 women) were randomly divided into two experimental groups (frequent vs. infrequent wins). The subjects used the thinking aloud procedure to verbalize their thoughts, which were then classified according to degree of rationality or irrationality. The results showed that irrational verbalizations outnumbered rational verbalizations in both groups. A few wins were sufficient to evoke an illusory perception of control.     

Patterns of Daily Time Use of Young Adults With or Without First-Episode Psychosis

This study compared patterns of daily activities and satisfaction with time use of young adults with first-episode psychosis and healthy volunteers. Fifty young adults participated in retrospective structured interviews on time use. Young adults with first-episode psychosis spend more time in sleep, passive leisure, and personal care activities, and less in total productive activities and education. No difference appeared for leisure, paid work, and household work, or satisfaction with daily time use. Reasons underlying dissatisfaction with daily time use differed between the groups. Clinical and research implications are discussed.     

The aim of psychoanalysis

The changing aims of psychoanalysis are discussed with reference to Money-Kyrle's paper on the subject. The theory of dammed-up libido, the theory of moral conflict and the theory of misrepresentations and perversion of reality which he described, all imply different aims. It is argued that, in addition, the theory of projective identification leads to a radical change in the aim of treatment which can now be formulated in terms of helping the patient regain lost parts of the self.     

Beyond the emotional event: Six studies on the social sharing of emotion

Abstract

We argue that emotion cannot only be conceived of as a short-lived and intrapersonal phenomenon. Rather, based on five theoretical arguments, we propose that the social sharing of an emotional experience forms an integral part of the emotional processes. A series of six studies investigated different aspects of this hypothesis. Study 1 showed that an overwhelming majority of people reported sharing their emotional experiences and that the memories of these experiences tended to come back spontaneously to their consciousness. No difference was found among emotions. Using a different procedure, Studies 2 and 3 replicated these findings in two different populations. In addition, these studies provided indications that women share their experiences with a wider array of individuals than do men. The first three studies did not find any differences among emotions, but they did not include shame. It could be argued that people are less inclined to socially share shame experiences which are typically elicited by breaking social rules. Study 4 specifically investigated this hypothesis. No differences among shame and other emotions were found except for the delay of the first sharing of the experience. Study 5 constituted a first investigation of whether the social sharing of emotion is also a significant process in now Western cultures. A comparison between Dutch and Surinamese people failed to reveal any significant difference. Based on the findings of the first five studies, a correlational model was designed in Study 6. It tested the interrelationships among disruptiveness of the emotion, social sharing, mental rumination, and recovery from the emotion disruption. A coherent pattern of findings emerged, showing that social sharing can be conceived as a bi-dimensional concept defined by features of amount and delay of sharing. In addition, both social sharing and mental rumination varied according to the disruptiveness of the emotion. Surprisingly, however, recovery could not be related to social sharing, mental rumination, or to the time elapsed since the episode.     

A Family Literacy Intervention to Support Parents in Children's Early Literacy Learning

This study examines a family literacy intervention conducted in two first-grade classrooms with culturally diverse student populations. In the treatment and control classrooms, six parents and a classroom teacher learned practices for building home-school partnerships. Data were analyzed to determine changes in home-literacy practices, increases in parents' knowledge literacy instruction, and changes in children's literacy achievement. Data analyses demonstrated that participating parents showed significantly greater usage of effective storybook reading strategies before and after reading. Parental and teacher participation resulted in statistically significant differences in students' scores on the Concepts of Print assessment, compared to students in the control classroom.     

How Bias Reduction Is Affected by Covariate Choice,Unreliability, and Mode of Data Analysis: Results From Two Types of Within-Study Comparisons

This study uses within-study comparisons to assess the relative importance of covariate choice, unreliability in the measurement of these covariates, and whether regression or various forms of propensity score analysis are used to analyze the outcome data. Two of the within-study comparisons are of the four-arm type, and many more are of the three-arm type. To examine unreliability, simulations of differences in reliability are deliberately introduced into the 2 four-arm studies. Results are similar across the samples of studies reviewed with their wide range of non-experimental designs and topic areas. Covariate choice counts most, unreliability next most, and the mode of data analysis hardly matters at all. Unreliability has larger effects the more important a covariate is for bias reduction, but even so the very best covariates measured with a reliability of only .60 still do better than substantively poor covariates that are measured perfectly. Why regression methods do as well as propensity score methods used in several different ways is a mystery still because, in theory, propensity scores would seem to have a distinct advantage in many practical applications, especially those where functional forms are in doubt.
