THE EFFECTS OF A GOOD BEHAVIOR GAME ON THE DISRUPTIVE BEHAVIOR OF SUDANESE ELEMENTARY SCHOOL STUDENTS

An endemic version of the Good Behavior Game was applied in a rural Sudanese second-grade classroom. Official letters of commendation, extra time for recess, victory tags, and a winner's chart were used as backup reinforcers. The class was divided into two teams, and the teacher indicated she would place a check on the board after every rule violation. The students were also told that the team with the fewest marks would win the game and receive the aforementioned prizes. After an initial adaptation period, the rate of disruption was charted across four treatment phases: viz., baseline I, introduction of the game, baseline II, and reintroduction of the game. It was observed that the game phases were associated with marked decreases in the rate of seat leaving, talking without permission, and aggression. The teacher, principal, parents, and students were consequently individually interviewed, and their comments spoke strongly for the social validity of the game.     

Power and influence in the environment of family therapy

This paper explores some of the ways in which family therapy theory and practice limits an appreciation of the contexts of families and family therapists. It focuses particularly upon how the rules which underline patterns of relationships in social systems are made and maintained more by one part of a system than by another, and considers this (a) within families, (b) within various aspects of the social environment of families, and (c) within the organizational contexts of family therapists. It then proposes that the systemic thinking which family therapists apply to families is potentially applicable to wider contexts including international relationships.     

"ENVIRONMENT SHOCK": A STUDY OF TOURISTS' REACTIONS TO TWO TROPICAL ISLANDS

The usefulness of links between tourism research and work in social psychology was considered. A diary-based study of tourists visiting tropical islands in North Queensland was discussed and changes in the day-to-day moods of tourists on the islands were reported. Some determinants of these mood changes were demonstrated using log linear analysis. Negative moods were more frequent on the second and third days of holiday, particularly during the evenings. It was argued that tourists experienced "environment shock" in visiting these resorts. Self-report health data confirmed this suggestion. Furthermore, tourists appeared to increase the number of self-initiated as compared to other-initiated activities during their holiday. It was concluded that the shift in activity patterns and the "environment shock" health problems were possible explanations of the day-to-day mood patterning reported in the study.     

The proper role of clusters in mathematical models of continuous recall

Previous research has shown that the number of words cumulatively recalled (N) at time (t) is a negatively accelerated function that reaches an asymptote as t → ∞. Research has also shown that the increase in N with t occurs in bursts or clusters. Several models purport to account for this cumulative recall curve in terms of cluster characteristics. The present research shows that previous models have not in fact successfully linked continuous recall to cluster characteristics. This research demonstrates that cluster models need to employ three empirical characteristics of clusters: T_b, the time between clusters; T_w, the average time between words within a cluster; and W_c, the number of words within a cluster. It is shown that these three quantities determine the cumulative recall curve, and these three quantities may in turn be characterized by four parameters. Of these four parameters, only three actually characterize the cumulative recall curve. Two parameters determine the initial slope and final asymptote of the curve, while a third parameter, which we introduce for the first time, characterizes the curve's shape. This latter parameter may be interpreted as the ratio ofthe time spent in retrieving and discarding a cluster that has been previously recalled to the amount of time spent in retrieving and outputting a newly encountered cluster. It is pointed out that previous success in fitting the cumulative recall data with a two-parameter function may be explained by the fact that this parameter lies in a restricted range about unity. Further experimental work is suggested to elucidate the behavior of this new parameter. Two models are then proposed to account for these characteristics of clusters and the shape of the recall curve.     

Reaction time and intelligence in the mentally retarted

Mildly retarted young adults were given simple and choice reaction time (RT) tests. Scores were also obtained on the Raven Progressive Matrices and the Figure Copying Test. Subjects' RTs increased as a function of stimulus complexity, and they were consistently subjects' intraindividual variability of response time was also markedly greater than that of non-retarded subjects. A number of RT parameters were found to be related to the measures of intelligence. Subjects seen on ten successive days showed low day-to-day stability of RT but no practice or fatigue effect.     

Relevant identity

We begin to fill a lacuna in the relevance logic enterprise by providing a foundational analysis of identity in relevance logic. We consider rival interpretations of identity in this context, settling on the relevant indiscernibility interpretation, an interpretation related to Dunn's relevant predication project. We propose a general test for the stability of an axiomatisation of identity, relative to this interpretation, and we put various axiomatisations to this test. We fill our discussion out with both formal and philosophical remarks on identity in relevance logic.     

Going As Far As We Can Go: The Jesus Proposal For Stretching Genes and Cultures

The Christian perspective on morality is examined under the rubric of "being like Jesus" and the "Jesus proposal for morality." The Peace People of Northern Ireland are examples of this proposal. Among the features of Christian moral thinking that are emphasized are: Jesus' concern for the future, the transformation that the future requires, human nature interpreted in terms of how it can undergo transformation, and self-giving love as the core of this transformation. Attention is given to the ways in which Jesus both radicalized and relativized the moral conventions of his day. Dialogue with sociobology comes into play when Jesus is viewed as a proposal for cultural evolution and a kind of biocultural mutation. Gerd Theissen's scholarship on Jesus' moral perspectives is given special attention.     

Language and Literacy in a Developmental Perspective

Snow et al. have provided an unusually comprehensive, even-handed, and thoughtful review of research on early reading development. Here we expand on an important theme—the value of a developmental and transactional perspective. Using results from studies of verbally precocious children and children with language impairments, we illustrate the qualitatively changing nature of the task of learning to read, and its connection to oral language development. We also discuss the bidirectional influence of adults and children on each other. This perspective has implications for what, when, and how to teach reading.
