Focus of attention,self-esteem,and the attribution of causality

An experiment was conducted to investigate how actors' attributions of causality are affected by their expectancy about the outcome of an action and their observation of the actual outcome while in a state of high or low objective self-awareness. In the presence or absence of a camera, subjects delivered therapeutic instructions which were expected to have a positive or a negative effect and which resulted in a positive or a negative effect on a supposedly phobic patient. Principal findings were that (1) attributions to self were greater under high objective self-awareness for positive relative to negative outcomes, (2) attributions to the patient were relatively great under high objective self-awareness when a positive outcome was expected but a negative outcome actually occurred. The results are discussed in terms of the joint role of focus of attention and self-esteem processes in the attribution of causality and in terms of their relationship to Duval and Wicklund's (1973) “focus of attention” attributional analysis.     

Attentional holism in visual word processing

Summary Decisions about the identity of an entire word are made more quickly than decisions about the identity of a letter within a word. Explanations of this whole-word advantage based on the time-course of the activation of different levels of unit detectors have given way to explanations based on how attention is allocated to the output of the detectors. Three studies were carried out to examine the role of attention in the whole-word advantage. In Experiment 1, cues as to the level of decision (whole-word vs. first-letter) facilitated component processing, a finding that suggests word level information is normally the focus of attention. In Experiment 2, identification of a probe item to the right of a display was longer when subjects prepared for a first-letter rather than a whole-word decision. That is, the spatial extent of attention is wider for whole-word decisions. In Experiment 3, probe latencies were longer when subjects prepared for a whole-word decision than when they prepared for a signalled probe trial. Preparation for a whole-word decision is not automatic in the sense of being free of capacity demands. The overall pattern of results leads to the conclusion that the whole-word advantage is an instance of attentional holism.     

Out-of-Body experiences in the blind

The theoretical significance of out-of-body experiences in blind people is explored. In this context I report results of a survey of a small sample of blind adults. It is concluded that we have yet to locate a case of an out-of-body experience in the blind that has critical implications for the interpretation of the experience among the general population.Acknowledgement hereby is given to the efforts of Margaret Kerr, Coordinator of Field Services for the Royal Blind Society of New South Wales, Australia, in supervising the collection of data reported in this paper.     

The Importance of Contraceptive Attributes Among College Students

This study assessed how ratings of the importance of contraceptive attributes varied with gender, age, relationship status, and contraceptive method usually used. In a classroom setting, 210 male and 217 female university students completed the 55-item Contraceptive Attribute Questionnaire (CAQ). Significant differences on importance ratings were found between women and men, age groups, women using barrier methods and women using the pill, and by relationship status. The underlying dimensions of the CAQ were investigated through factor analysis, and somewhat different factors emerged for men and women. Implications for the provision of family planning services to college students are discussed.     

Dichotic sequence discrimination: The effect of stimulus intensity and background noise level

Dichotic temporal discrimination of clicks over the range of separation of 2 ≤ Δt ≤ 96 msec is nonmonotonic, being V- or U-shaped with two maxima, one at very short separations (?t≤4 msec) and one at long separations (Δt ≥ 64 msec). Decreasing the level of the stimuli or increasing the level of background noise results in an overall decrement in discrimination level and a widening of the base of the function to make it more U-shaped. These effects are expressed in shorter Δt thresholds for the left limb of the function and longer Δt thresholds for the right limb of the function     

An optimum value for detection probability

In many psychoacoustic experiments, an experimenter wishes to determine the effects of one or more treatments Ito the subjects, or to the stimuli, or to both) with as little experimental labor as possible. The experimenter is often able to control the similarity of the stimuli and is thus free to choose a base level of performance before the treatment is applied. On the basis of the model presented in this paper, the base level of performance that best enables any change in performance due to the treatment to be detected is predicted. A relatively high base-level performance of 95% correct discrimination results from the model, although practical constraints may dictate a somewhat lower value. An experiment (involving pitch discrimination) that provides data supporting the model is also reported. The model is applicable only to the two-alternative/forced-choice experimental paradigm.     

Speech competence of children vulnerable to psychopathology

Verbal productivity and cohesion and reference patterns of children of schizophrenics (N=23), unipolars (N=43), bipolars (N=38), and normals (N=53) were assessed using the Rochester and Martin (1979) evaluation system. Children of all offspring groups could be discriminated from one another, with children of schizophrenics showing the most deviant speech performance across all dependent measures. Children of schizophrenics were less verbally productive and had poorer patterns of cohesion between ideas than children of normals. In addition, they produced more unclear and ambiguous references to previously mentioned ideas than did children of normals. The consistency of deviance and performance on specific dependent variables in these children at risk for schizophrenia was similar to the speech performance of thought-disordered schizophrenics. Possible explanations for these similarities were discussed and evaluated.This research was supported by grant number MH21145 from the National Institute of Mental Health and by funds from the William T.
