Selective attention and changes in clinical state

Thirty inpatients of a psychiatric unit were given the Mini-Mult and a series of auditory selective attention tasks in order to test the hypotheses that (1) impaired attention is related to degree of pathology, and (2) improvement in clinical state leads to improved ability to selectively attend. The results showed that the relationship between the Mini-Mult and the listening tasks is significant only when the subjects had to exclude irrelevant stimuli (interference condition). The results also indicated that the relationship between clinical changes and changes in attentional performance is significant. The findings were discussed in terms of a quantitative theory of attention.     

Asymmetry of cognitive functioning as a possible predictor for vocational counseling and personnel classification

Neuropsychological research indicates the asymmetrical functioning of the cerebral hemispheres. The right hemisphere appears to specialize in global, synthetic, spatial, time-independent processing, whereas the left hemisphere is dominant in analytic, verbal, sequential, time-dependent processing. It is proposed here that in tasks, jobs, and occupations entailing hemisphere-specific abilities, personnel with superior functioning of the relevant hemisphere would perform more proficiently. A test battery designed to assess hemispheric dominance was administered to two groups, Economics and Arts students. Significant differences in mean performance were found between groups, as predicted. The findings suggest that the identification of individual patterns of hemispheric specialization may be useful for matching people's abilities with job demands.     

Differential acquisition of conditioned suppression in rats with increased and decreased luminance levels as CS + s

Using a conditioned suppression procedure, it was demonstrated that suppression of responding was substantially enhanced when the CS signaling the occurrence of shock was an increment in luminance level (bright CS), relative to an equivalent decrement in luminance level serving as a signal for shock (dim CS). The results of a pseudoconditioning control procedure illustrated that the differential effectiveness of the bright and dim CSs was dependent upon explicit CS-US pairings. The bright and dim stimuli were found to produce equivalent rates of conditioning when they were used to signal the availability of reinforcing stimuli in an appetitive discrimination procedure. The interpretation considered to be most consistent with the data is associative in nature; rats may be brought into the experimental setting prepared to associate bright light with danger and contraprepared to associate dim light with danger.     

Christ‐Centered Concreteness: The Christian Activism of Dietrich Bonhoeffer and Martin Luther King Jr.

Dietrich Bonhoeffer and Martin Luther King Jr. were both pastors and theologians who wrestled with the meaning of Christ‐centered faithfulness for their time. They were advocates of social justice and human rights who resisted the temptation towards a secularizing two‐realms split that makes Christianity a private life religion; they defied contemporary laws and cultural norms, and they faced opposition to their work from many of their fellow Christians. We may learn from their prophetic witness for Christian faithfulness in our contexts by paying attention to their respective interpretations of the way of Jesus.     

Acquisition of a free-operant-appetitive response in pigeons as a function of prior experience with response-independent food

Deficits in learning to escape from electric shock following exposure to response-independent preshocks have frequently been reported and have been referred to as learned helplessness. Experiments were conducted in order to determine whether a phenomenon similar to learned helplessness could be induced in appetitive free-operant procedures with pigeons. Subjects received preliminary training under one of the following conditions; protracted exposure to response-dependent grain presentations (key pecking), protracted exposure to response-independent grain deliveries, or short-term hopper training. Subjects were then tested for acquisition of a treadle-pressing response which was the only means of access to grain in the experimental chamber. The acquisition of the treadle-pressing response was retarded following protracted exposure to response-independent grain deliveries and the degree of this retardation was related to the complexity of the response-reinforcer contingency.     

The biological function of Pavlovian conditioning: Learned inhibition of aggressive behavior in territorial fish

Following Pavlovian discrimination training, stimuli predicting the appearance of a territory intruder (an excitatory conditional stimulus, CS+) or the absence of that event (an inhibitory conditional stimulus, CS−) were presented to pairs of territorial male fish immediately before their first aggressive interaction. Pairmates that both received excitatory stimuli prior to the confrontation were significantly more aggressive than a control group which received the same training but which received neither a CS+ nor a CS− in the test. Pairmates in which both received a CS− were significantly less aggressive than the control group. In these three groups, no differences in aggression were observed between the individual members of a single pair. Two additional groups were composed of pairs whose members received different stimuli prior to the test. Although no differences were found between pairmates in the group in which one member received a pretest CS− while the other member received no stimulus presentation, large differences in aggressive behavior were obtained when one fish received a CS+ and its pairmate received a CS−. We discuss the behavioral ecology of terriorial behavior in fish and attempt to show the potential importance of these results in this naturalistic context. In addition, we discuss the implications of an ecological approach for causal analyses of inhibitory learning.     

Social problem solving and mother-child interactions of educable mentally retarded children

Mothers of retarded children and nonretarded children were observed and videotaped as they interacted with their own child in a seminaturalistic situation, requiring teaching, cooperation, and free play. The child's social problem-solving abilities were assessed independently. The Vineland scale was employed to provide some convergent evidence of social problem-solving as a component of social competence. Twelve educable mentally retarded and 19 nonretarded 10-year-old children and their mothers comprised the sample. For the mentally retarded group, it was found that the higher maternal directiveness, the lower the child's social problem-solving skills. Mothers who often gave the child opportunity for decision-making and social influence had children with higher problem-solving skills. The retarded children produced significantly fewer different strategies for solving social problems, but gave a wider range of strategies than has been found in previous research. There was some support that social problem-solving skills are related to social maturity.     

Immigrants preparing for their second career: The behavioral strategies adopted

On the basis of the assumption that career change for immigrants is not generally anticipated and is characterized by status incongruence, this research tested the action of the dissonance model on 89 immigrants who were obliged to prepare for a new occupation. Four coping strategies were found combining high vs low level of self-image and vocational involvement with positive vs negative attitudes toward work and authority figures at the places of work. The comparative efficiency of these strategies was tested—both with regard to an objective vocational criterion and to satisfaction and optimism regarding the future.
