ALTRUISM: TOWARD A PSYCHOBIOSPIRITUAL CONCEPTUALIZATION

Altruism, defined here as a regard for or devotion to the interest of others with whom we are interrelated, is pitted against two other dispositions in human beings: nepotism and egoism. We propose that to become fully human is to become more altruistic. We describe how altruism is mediated by our physiology, is expressed in our psychological development, is evolving in our social institutions, and becomes the moral communities that enforce our sense of right and wrong. A change in any one of these influences changes our disposition—changes who we are and what we do—potentially making altruism more possible in the world.     

Effect of instructional units on the analysis of related and unrelated skills

84 majors in elementary education were divided into three groups, one control group and two experimental groups. The control group received no instruction in skill analysis while the experimental groups were instructed via videotape in either the instep kick in soccer or in throwing, catching, and striking skills. All three groups were given a skill-analysis test composed of throwing, catching, and striking skills. Statistical analysis yielded significant effect for those who viewed the throwing, catching, and striking videotape. No effect was found for the control group or the group who viewed the soccer-instep videotape. The results suggest specificity may be as important in skill analysis as in acquisition.     

A comparison of generalization functions and frame of reference effects in different training paradigms.

Six experiments were carried out to compare go/no-go and choice paradigms for studying the effects of intradimensional discrimination training on subsequent measures of stimulus generalization in human subjects. Specifically, the purpose was to compare the two paradigms as means of investigating generalization gradient forms and frame of reference effects. In Experiment 1, the stimulus dimension was visual intensity (brightness); in Experiment 2, it was line orientation (line-angle stimuli). After learning to respond (or to respond "right") to stimulus value (SV) 4 and not to respond (or to respond "left") to SV2 (in Experiment 1) or SV1 (in Experiment 2), the subjects were tested for generalization (recognition) with an asymmetrical set of values ranging from SV1 to SV11. Go/no-go training produced peaked gradients, whereas choice training produced sigmoid gradients. The asymmetrical testing resulted in a gradual shift of the peak of responding (go/no-go group) or in the point of subjective indifference (PSI; choice group) toward the central value of the test series; thus, both paradigms revealed a frame of reference effect. The results were comparable for the quantitative (intensity) and the qualitative (line-angle) stimulus dimensions. Experiment 3 compared the go/no-go procedure with a yes/no procedure in which subjects responded "right" to SV4 and "left" to all other intensities and found no differences between these procedures. Thus the difference in gradient forms in go/no as opposed to (traditional) choice paradigms depends on whether one or two target stimuli are used in training. In Experiment 4, in which visual intensity was used, the shift in the PSI following choice training varied positively with the range of asymmetrical test stimuli employed. In Experiment 5, also with visual intensity, the magnitude of the peak shift following go/no-go training varied as a function of overrepresenting a high or a low stimulus value during generalization testing. Experiment 6, with line angles, showed that the PSI following choice training varies in a similar way. The frame of reference effects obtained in these experiments are consistent with an adaptation-level model.

Self-focused attention in schizophrenic patients with and without auditory hallucinations and normal subjects: A comparative study

Self-focused attention has been implicated in a number of psychiatric disorders, but little research has examined this in schizophrenic subjects. In this study, a sample of schizophrenic patients experiencing auditory hallucinations, schizophrenic patients not experiencing auditory hallucinations and normal controls were asked to complete the private self-consciousness subscale of the Self Consciousness Scale. It was found that patients experiencing auditory hallucinations exhibited significantly higher levels of self-focus than those not experiencing hallucinations, although they did not differ from normal subjects. It was also shown that level of self-focus predicted whether or not subjects experienced hallucinations. These results, and their implications, are discussed with reference to the literature.     

Manipulation of stimulus onset delay in reading: evidence for parallel programming of saccades

On-line eye movement recording of 12 subjects who read short stories on a cathode ray tube enabled a test of direct control and preprogramming models of eye movements in reading. Contingent upon eye position, a mask was displayed in place of the letters in central vision after each saccade, delaying the onset of the stimulus in each eye fixation. The duration of the delay was manipulated in fixed or randomized blocks. Although the length of the delay strongly affected the duration of the fixations, there was no difference due to the conditions of delay manipulation, indicating that fixation duration is under direct control. However, not all fixations were lengthened by the period of the delay. Some ended while the mask was still present, suggesting they had been preprogrammed. But these "anticipation" eye movements could not have been completely determined before the fixation was processed because their fixation durations and saccade lengths were affected by the spatial extent of the mask, which varied randomly. Neither preprogramming nor existing serial direct control models of eye guidance can adequately account for these data. Instead, a model with direct control and parallel programming of saccades is proposed to explain the data and eye movements in reading in general.     

The effects of explicit timing and feedback on compositional response rate in elementary school children

The effects of several variables on compositional response rate were investigated in three classrooms. After establishing baseline composition rates in each of the three classrooms, an experimental phase was introduced that consisted of: explicit timing of the children's composition period with a stopwatch, immediate feedback on the number of words each child produced, public posting of the greatest number of words written by each child to date, and instructions to try to exceed their highest score. In the second-grade classroom, these conditions were introduced, removed, and re-introduced. In two fifth-grade classrooms, these conditions were introduced according to a multiple baseline, across classes. In all cases, introduction of the experimental conditions led to a doubling of rate of words written by students and an increase in subjective quality ratings of compositions made by independent judges.
