A theory of behavior interaction in dyads: A structuralist account

A theory from the behavioral and social sciences is presented from the structuralist point of view. A more comprehensive theory-net is outlined, some basic terms and core assumptions are formulated, and an expansion of the theory towards two intended applications is given. Finally, some results of a first empirical test of the theory are reported. The aim of the paper is to show that the structuralist account of scientific theories is not confined to mathematical theories from the natural sciences, but can also be applied to relatively informal constructions of the behavioral and social sciences.     

Lunchroom noise control using feedback and group contingent reinforcement

Reduction of noise levels in an elementary school lunchroom was examined as a function of feedback and feedback plus reinforcement using group contingency procedures. Feedback consisted of signals from a traffic light, with green indicating acceptable levels, yellow indicating levels approaching undesirable, and red indicating unacceptable levels. Other behaviors, including running, hitting, pushing, and kicking, were measured incidentally. Results indicate that feedback plus reinforcement was effective in reducing noise levels. Feedback only was also effective, but to a lesser degree. No response-response relationship was found to exist between noise level and the other behaviors.     

Teaching boys with severe mental retardation to serve themselves during family-style meals

Three institutionalized adolescents with severe mental retardation were taught the socially valid skill of serving themselves during family-style meals. A nine-step task analysis was used as a guide for teaching the students, combined with verbal prompts, physical guidance, praise and correction. A multiple base-line design across three subjects was used to evaluate training. All three students successfully acquired the skill, which was seen as a step towards normalization and community placement.     

Predicting children’s liking of school from their peer relationships

Prior studies have established that children’s peer relationships and school adjustment are associated. The main aims of the current study were to test if four measures of peer relationships (Peer Acceptance, Presence/Absence of Best Friend, Number of Friends, and Perceived Peer Support) could predict School Liking concurrently and longitudinally across a 6 month period, and if gender moderated any of those associations. An opportunistic sample of girls and boys (N = 429 at Time 1 and N = 214 at Time 2) was drawn from 10 junior schools in the UK. A short-term longitudinal survey design was employed in which self- and peer-report measures were administered in small groups at Time 1 (November/December) and then again at Time 2 (May/June) of the same academic year. Concurrently, all four peer relationship variables emerged as significant non-unique predictors (i.e. not controlling for variance shared among the predictors) of School Liking; Peer Acceptance and Perceived Peer Support emerged as significant unique predictors (i.e. after controlling for variance shared among the predictors) of School Liking; the set of four peer relationship variables together accounted for a significant amount of variance in School Liking; and gender moderated the association between Peer Acceptance and School Liking. Longitudinally, Peer Acceptance was a significant unique predictor of changes in School Liking. This study adds to the literature by providing evidence of which specific peer relationships predict School Liking, and they support the call for interventions to enhance those relationships.     

Cross-sectional and longitudinal relations among peer-reported trustworthiness, social relationships, and psychological adjustment in children and early adolescents from the United Kingdom and Canada

Trustworthiness was examined in children and early adolescents from two countries. In Study 1,505 children in the fifth and sixth school years in the United Kingdom (mean age = 9 years 7 months) were tested across an 8-month period. In Study 2,350 sixth- through eighth-grade Canadian children and early adolescents (mean age = 12 years 11 months) were tested across a 1-year period. Participants completed measures assessing trustworthiness (ratings of promise and secret keeping by peer group and also by best friend in Study 1), assertiveness (Study 1), prosocial behavior (Study 2), social relationships (friendships and peer preference), and psychological adjustment (self-esteem, depressive symptoms, and loneliness). Peer-reported trustworthiness was positively associated with, and predicted changes across time in, the number of friendships. The observed relations were found to be statistically independent of peer preference and peer-reported assertiveness or prosocial behavior. Trustworthiness was found to be positively associated with peer preference (Study 1 and Study 2) and psychological adjustment (Study 1).     

Luria in Uzbekistan: The Vicissitudes of Cross-Cultural Neuropsychology

If the material conditions of culture shape cognitive structures, as Luria and Vygotsky argued, the extraordinarily deep and rapid restructuring of historical forms (Luria, 1971, 265) in the Soviet Republics that followed the Bolshevik revolution of 1917 provided a natural laboratory to determine whether processes of modernization changed traditional ways of thinking. This was the purpose of Luria's 1931 expedition to the Soviet Republic of Uzbekistan in central Asia. Luria's initial reports attracted vitriolic criticism because he had allegedly belittled primitive Uzbeki culture. The lasting importance of the Uzbek expedition is its emphasis on culture as a determinant of cognitive processes that remains valid to the present: in 1984, Gilbert replicated Luria's field studies in South Africa with near-identical results. Yet current neuropsychology has been slow to recognize the need for culturally sensitive assessment.     

Family therapy in primary health care: Skills training and outcome evaluation

Some of the theoretical tenets of family therapy such as emphasis on the activation and utilization of existing family resources and the importance it accords to context appear to have a good fit with primary health care's commitment to empowering individuals in their struggle against ill health and the circumstances in which it occurs. This paper explores the possibility of teaching a problem-solving approach to family therapy to nurses in a South African primary health care system. Training consisted of conceptual, pragmatic, and self-growth exercises, and trainees' conceptual and performance skills were compared to the skills of a group of untrained nurses.We thank Bukelwa Selema, co-trainer on the program, for her contributions to joining effectively with the nurses and enriching the experiential process. We also thank Dr. P.J. Beukes, Dr. J.H. Olivier, Dr. G.M. Louw, Matron L.C. Langley and other staff in the Soweto primary health care system for their support. In particular, we are grateful to nursing sisters Martha Nkoane and Millicent Matomela, who roleplayed clients on the videotaped training modules. We are also grateful to Edcent Williams, who was one of the videotape raters, and Mike Spruce, Ricky Snyders, Nico Cloete, Ricky Mauer, and Brenda Radebe for their inputs at various stages of designing and implementing the programme.     

Cruelty's rewards: the gratifications of perpetrators and spectators

Cruelty is the deliberate infliction of physical or psychological pain on other living creatures, sometimes indifferently, but often with delight. Though cruelty is an overwhelming presence in the world, there is no neurobiological or psychological explanation for its ubiquity and reward value. This target article attempts to provide such explanations by describing three stages in the development of cruelty. Stage 1 is the development of the predatory adaptation from the Palaeozoic to the ethology of predation in canids, felids, and primates. Stage 2, through palaeontological and anthropological evidence, traces the emergence of the hunting adaptation in the Pliocene, its development in early hominids, and its emotional loading in surviving forager societies. This adaptation provides an explanation for the powerful emotions - high arousal and strong affect - evoked by the pain-blood-death complex. Stage 3 is the emergence of cruelty about 1.5 million years ago as a hominid behavioural repertoire that promoted fitness through the maintenance of personal and social power. The resulting cultural elaborations of cruelty in war, in sacrificial rites, and as entertainment are examined to show the historical and cross-cultural stability of the uses of cruelty for punishment, amusement, and social control.Effective violence prevention must begin with perpetrators, not victims. If the upstream approaches to violence prevention advocated by the public-health model are to be effective, psychologists must be able to provide violence prevention workers with a fine-grained understanding of perpetrator gratifications. This is a distasteful task that will compel researchers to interact with torturers and abusers, and to acknowledge that their gratifications are rooted in a common human past. It is nonetheless an essential step in developing effective strategies for the primary prevention of violence.
