In charge but not in control: the management of teaching relationships by adults with low perceived power

The paradoxical use of punitive force by adults with low perceived power was explored in teaching interactions. Punitive force was measured by the intensity of physical effort used in operating controls that displayed negative feedback to child trainees. Women who differed in perceived power were assigned to (a) situations in which they had high, low, or ambiguous control and (b) responsive, unresponsive, or ambiguously responsive children. Women with low perceived power--when given ambiguous control--were more likely than other women to (a) use high levels of punitive force and (b) show elevated levels of autonomic arousal. Arousal, in turn, partially mediated the relationship between perceived power and use of force. Women with low perceived power were also more likely to attribute intentionality to children whose behavior was ambiguous. Results were interpreted as having implications for violence within adult-child relationships.     

Self-deprecation and estimates of body size in women.

The subject of body image in women has received considerable attention particularly with concern about its relationship to behaviours such as dieting. This study investigated the reported tendency of women to see thinness as desirable and to perceive themselves as fatter than others do. This tendency is inconsistent with the general findings on self-enhancement that show that people (including women) generally overestimate the extent to which they possess desirable characteristics. Thus, the purpose of this study was to investigate whether the tendency for women to report themselves as fatter than others perceive them is part of a general tendency to deprecate themselves on socially desirable qualities or whether this deprecation is restricted to body size. To investigate this, 29 female undergraduates in psychology participated in a study comparing own and others' perceptions of body size, attractiveness, sexiness, intelligence, and friendliness. Compared with the ratings of them given by others, women tended to make self-enhancing judgements of their attractiveness, sexiness, intelligence, and friendliness. This was not found for body size, however, for which self-ratings tended to be the same as those made by others. The failure to find self-enhancing judgements of body size is discussed in terms of the relatively unvarying standards presented to women concerning ideal body size compared to the more subjective standards used to evaluate other qualities.     

The Reliability and Validity of the ‘Rejection of Christianity Scale’ among Northern Irish Students

The present aim was to examine the reliability and validity of the ‘Rejection of Christianity Scale’ (Greer & Francis, 1992) among a sample of Northern Irish undergraduate students. A slightly modified version of the ‘Rejection of Christianity Scale’ was administered alongside questions of religiousness and practice. Among a sample of 217 Northern Irish undergraduate students, support was found for the reliability and unidimen‐sionality of the ‘Rejection of Christianity Scale’. The construct validity of the scale was demonstrated with males displaying more signs of rejecting Christianity than females. Furthermore, higher scores on the ‘Rejection of Christianity Scale’ were significantly associated with lower levels of self‐reported religiousness, and lower frequency of church attendance. Limitations of the present study are presented and a further possible modification of the ‘Rejection of Christianity Scale’ is presented.     

A study of the classification capabilities of neural networks using unsupervised learning: A comparison withK-means clustering

Several neural networks have been proposed in the general literature for pattern recognition and clustering, but little empirical comparison with traditional methods has been done. The results reported here compare neural networks using Kohonen learning with a traditional clustering method (K-means) in an experimental design using simulated data with known cluster solutions. Two types of neural networks were examined, both of which used unsupervised learning to perform the clustering. One used Kohonen learning with a conscience and the other used Kohonen learning without a conscience mechanism. The performance of these nets was examined with respect to changes in the number of attributes, the number of clusters, and the amount of error in the data. Generally, theK-means procedure had fewer points misclassified while the classification accuracy of neural networks worsened as the number of clusters in the data increased from two to five.Acknowledgements: Sara Dickson, Vidya Nair, and Beth Means assisted with the neural network analyses.     

Prosody and the processing of filler-gap sentences

This study was designed to explore the effects of linguistic prosody on the processing of filler-gap sentences. We designed two experiments to determine first whether the sentence processor uses information contained in the prosodic contour of an utterance during on-line processing, and second the form that information may take. In Experiment 1, we found that prosody apparently influences when listeners posit gaps on-line. In Experiment 2, we obtained acoustic evidence that gaps are represented in the prosodic contour of an utterance. The results of this study support a view in which prosody contributes very early to on-line structure building mechanisms during sentence processing.The work reported in this paper was supported by NIH grant DC00494.     

A comparative analysis of the effects of social skill training and teacher-directed contingencies on social behavior of preschool children with disabilities

This study investigated the effects of an analog social skill training program and a teacher-directed contingency strategy on promoting social responding among four preschool children with mild disabilities and their peers. The social skill training program consisted of five lessons targeting the skill areas: Initiating, responding, and maintaining social interactions. The teacher directed contingency consisted of prompting target children when they were not socially involved with peers, and providing verbal praise when they were socially involved with peers. Subjects were divided into two training pairs and received both interventions in a reversal design. Presentation order was counterbalanced across the two training pairs. Results indicated that the teacher directed contingency was more effective in promoting higher levels of social responding in a free-play setting. Results also suggest that social skill training may not always be a necessary prerequisite to promote increased social interactions among children who display low rates of social interaction with peers, but possess necessary skills.     

Affective deficits and pain insensitivity in schizophrenia

Affective deficits have long been considered a prominent feature of schizophrenia and play a central role in recent theory and research on the pathophysiology of this disorder. However, it has recently been argued that current approaches to the conceptualization and assessment of affective flattening in schizophrenia are confounded by the social and neuromotor deficits that are also prevalent in this disorder. Insensitivity to pain in individuals with schizophrenia — a phenomenon that has been reported frequently but never systematically investigated — provides one approach to examining affective flattening unconfounded by social and neuromotor deficits. Two studies are described in which signal detection theory measures of thermal pain sensitivity were examined in patients with schizophrenia, mood disorder, and normal controls; in addition, in the patients with schizophrenia, the relationships between these measures and measures of affective deficits were examined. Patients with schizophrenia had significantly poorer sensory discrimination of painful thermal stimuli than control subjects, but did not differ from controls with respect to their response criterion for reports of pain; patients with mood disorder had a significantly higher (i.e., more stoical) criterion for reports of pain than controls. As predicted, among the patients with schizophrenia, higher response criterion was significantly correlated with greater affective flattening and less intense affective experience (as well as with fewer positive symptoms and poorer premorbid adjustment). The results of these studies suggest that pain insensitivity in schizophrenia may reflect affective as well as sensory abnormalities, and that pain insensitivity in schizophrenia may provide a method for studying affective flattening in this disorder that is relatively independent of the social and neuromotor deficits that confound existing measures of this symptom. Continued examination of the relationship between pain insensitivity and affective deficits in schizophrenia is also important because numerous clinical reports have suggested that pain insensitivity is detrimental to health and can have life-threatening consequences in individuals with this disorder.This research was supported, in part, by research grants from the National Institute of Neurological Disorders and Stroke to Robert H. Dworkin (NS-30714) and W. Crawford Clark (NS-09263, NS-20248).     

Pairs of Latin squares that produce digram-balanced Greco-Latin designs: A BASIC program

It is possible to create pairs of Latin squares that are digram balanced (in other words, that counterbalance immediate sequential effects) in a Greco-Latin design. A behavioral researcher can use these squares to design an efficient, well-balanced study without relying on chance. Researchers can apply these squares to any experiment in which they must pair conditions with different stimuli in a within-subject design. For experiments with a large number of conditions, however, the procedure is very time-consuming if done manually. A BASIC program is described that generates the correct pairs of squares for experiments with as many as 80 conditions.

TEACHING MEMORIZED SPELLING WITH A MICROCOMPUTER: TIME DELAY AND COMPUTER-ASSISTED INSTRUCTION

A computer-assisted instruction program was evaluated that used a constant time-delay procedure to teach 5 students 18 spelling words. In addition to delivering the instructional procedure, the program managed the presentation of training content based on individual student responding and collected instructional data on individual student performance. The procedure was effective at teaching 4 of the 5 students the words, and generalization occurred from the computer-delivered keyboard response format to a teacher-delivered hand-written response format. Maintenance data varied among the students. The study demonstrated the feasibility of using microcomputers to deliver time-delay instruction in special education classrooms and suggested several research questions related to specific features of microcomputer-delivered time-delay instruction.
