The effects of modelling and instruction on the problem-solving performance of preschool children in Papua New Guinea and Australia(1)

Children from preschools in Australia (AUST) were compared with indigenous children from preschools at Hanuabada and Kaugere in Papua New Guinea (PNG). The effects of modelling and instruction, separately and together, on their performance in problem-solving tasks were evaluated. In addition, a within-culture comparison was made of the two PNG groups. ANCOVAS were computed with the factors group (PNG-AUST and Hanuabada-Kaugere), treatment condition (no modelling with no instruction, instruction alone, modelling alone, and instruction with modelling) and sex. Mental and chronological ages were included as covariates. The results showed that (a) the strategy adoptions were more frequent in the instruction with modelling and in the instruction alone conditions than in the control condition and the modelling alone condition was not different from the control condition, (b) PNG children in the three experimental conditions adopted the advocated strategy about three times as often as the Australian children, (c) no differences occurred between girls and boys in strategy adoptions but girls were quicker in completing the tasks than boys, and (d) chronological age was a predictor of group effects. These results were discussed in terms of a possible cognitive developmental mechanism in the performance of modelled behaviours.     

Reliability and validity of IJR Behavior Checklist scores: Number versus pathology level of symptoms

The parent, teacher, and clinician forms of the IJR Behavior Checklist yield four summary scores (checklist total score, pathology weighted total score, mean pathology score, and highest 5 items' mean pathology score). The checklist total score is essentially a symptom count with a double-weighting for frequent/intense occurrence; the other three scores incorporate item pathology weights. All four summary scores were shown to have moderately high validity as measures of the construct child/ adolescent psychopathology: They differentiated between well-adjusted and clinical subsamples at the .001 level. The two scores based entirely on the pathology weights manifested less satisfactory reliability than the two scores reflecting primarily number of symptoms, but surpassed the latter in power to discriminate between psychotic and nonpsychotic patients.     

Consistency as a Factor in Predicting Grades

This study attempted to determine whether individual differences in intra-individual consistency are reliable over time and whether future grades can be predicted more accurately for consistent students—those whose grades do not vary much from course to course—than for students with “spotty” records. Measures of intra-individual consistency were computed from grades obtained early in school and from grades obtained later for several samples of students. These measures showed no reliability over time, and there were no differences between consistent and inconsistent students with regard to the accuracy of prediction of future grades. It was recommended that considerable caution be used in attributing any significance to the degree of consistency or inconsistency manifested by a student's academic record.     

A programmable proximity-contact sensor to detect location or locomotion of animals

A simple electronic device to detect location or to track locomotion of small animals is described. The device is based on anantenna effect—it responds to a change in capacitance as the body of the animal passes between an antenna and one of a series of contact plates. A digital address system is incorporated that is capable of electronically polling the contact plates according to instructions from a data-acquisition system (DAS). Any DAS capable of generating an address of two bits or more and of reading a one-bit data line may be employed. The device is ideal for mazes or other apparatus in which the exclusion of stereotypical behaviors is desired.     

EFFECTS OF A VIDEOTAPE FEEDBACK PACKAGE ON THE PEER INTERACTIONS OF CHILDREN WITH SERIOUS BEHAVIORAL AND EMOTIONAL CHALLENGES

Peer interactions are among the greatest challenges experienced by children who have severe emotional and behavioral problems. This study evaluated an intervention package designed to increase the ratio of these children's desirable to undesirable interactions. The package included three principal components: (a) observation of videotapes following regularly scheduled peer activity sessions; (b) self-evaluation of the children's peer interactions observed on the videotapes; and (c) delayed feedback and reinforcement for desirable peer interactions. Five students from two elementary schools participated. Multiple baseline designs and one reversal were used to evaluate the effects of the intervention package. The results showed that the intervention produced lower levels of undesirable peer interactions and higher ratios of desirable to undesirable interactions for all participants. The results are discussed in regard to their conceptual and applied implications and in terms of specific directions for future research.     

The Ismaili sect in London: Religious institutions and social change

The Ismailis in London are a community attempting to adapt the stock of Ismaili theoretical concepts to the explanation and control of events in a changed and changing social situation. This article is concerned with assessing the role of Ismaili religious institutions in this process of adaptation. It will be argued that because the Ismaili belief system emphasizes the irrelevant and transitory nature of Ismaili religious institutions, the true role, paradoxically, of these religious institutions is preserved, and as a consequence they remain relevant to Ismailis.     

Examining business students' career preferences: A perceptual space approach

A methodology for examining career preferences is proposed. The method uses perceptual mapping techniques and external preference analysis to assess the attributes individuals believe are important. The results of a study undertaken to test the methodology are reported and it appears that such results can be useful in analyzing reasons for career preferences.     

CHOICE MAKING TO PROMOTE ADAPTIVE BEHAVIOR FOR STUDENTS WITH EMOTIONAL AND BEHAVIORAL CHALLENGES

Two analyses investigated the effects of choice making on the responding of elementary school students with emotional and behavioral challenges. In the first analysis, 2 participants were given choices from menus of academic tasks, all of which were pertinent to their educational objectives in English and spelling, respectively. Reversal designs showed that the choice-making conditions increased task engagement and reduced disruptive behavior for both students. An additional analysis was performed with a 3rd student in an effort to further distinguish the effects of choice making from preference. In this study, one of the no-choice phases was yoked to a previous choice-making condition. This analysis demonstrated that the choice-making condition was superior to baseline and yoked control phases as determined by levels of task engagement and disruptive behavior. The findings of the two analyses contribute information relevant to students with emotional and behavioral disorders, and to a growing literature on the desirable effects of choice making for students with disabilities and challenging behaviors.     

What are careers officers thinking of? How information cues are selected and used in careers interviews

This paper explores the information-seeking practices of careers officers during careers interviews. Research in decision-making is used to establish hypotheses, with a focus on findings in the fields of heuristics, cognitive mapping and medical diagnostics. Sensitive areas for careers guidance providers in this research field are outlined. A small-scale research project is described, which indicated support for several of the hypotheses. A model is suggested of how careers officers may elicit and use information cues in order to mentally match clients' post-16 choices against perceived opportunities. The implications for careers officer practice and careers service fundholders are discussed.
