Effects of arousal on human visual dominance

Human attention research has found that vision controls attention when competing against other sensory modalities, for example, audition, proprioception, taction. Similarly, animal learning experiments have demonstrated visual attentional control when animals are positively motivated but auditory control when aversively motivated. The experiments with animals suggest a way of attenuating visual dominance in humans. Three experiments using human subjects explored the degree of visual versus auditory control exhibited in the presence of different arousal states. In Experiments 1 and 2, an electric shock and a threat of electric shock, respectively, to the subject’s finger resulted in auditory attentional control In Experiment 3, a tactile stimulus resulted in attenuated visual control. The results of these experiments are discussed in relation to the evolutionary advantage conferred by such attentional strategies.     

Food-reinforced inhibition of conditioned salivation in dogs.

Twelve dogs salivated to a tone that was followed by food, but not to a noise for which there was an added response dependency. The noise was followed by food if and only if they did not salivate. The addition of this response dependency vitiated the classically conditioned response to the noise. A yoked-control group of 6 dogs receiving the same sequences of stimuli and food salivated to both the tone and noise stimuli.     

Family therapy in treatment of the deaf: a case report.

Deaf patients with psychological problems have developmental handicaps and clinical characteristics that reduce the effectiveness of traditional modes of psychotherapy. Attempts have been made to utilize individual and group therapy, but family therapy has been largely overlooked as a method of alleviating problems of the deaf. Clinical and research writings provide us with rich insights into the family dynamics of the deaf. These data suggest to the authors that the problems of deaf individuals are largely related to family problems, and therefore merit a family orientation as the focus for treatment. This paper describes an attempt to apply family therapy with a range of deaf patients over a period of two years. From a review of their work, the authors conclude that family therapy can be effective, particularly in the treatment of deaf adolescents and children.     

Classification and validation of family climate subtypes in Kibbutz fathers of disabled and nondisabled children

The aim of the study was to investigate the impact of disabled children on their fathers. Perceptions of family climate, sense of coherence, and satisfaction from family life were measured among 66 fathers of disabled children and among 74 fathers with nondisabled children in an Israeli kibbutz. The fathers of disabled children showed lower sense of coherence, derived less satisfaction from family life, and viewed their families as less encouraging of personal growth among family members. Four subtypes of family climate patterns, perceived by fathers of disabled children, were identified by cluster analysis and validated by the sense of coherence and global family satisfaction measures. Cluster analysis for the fathers of nondisabled children replicated the subtypes identified. The four subtypes were conceptualized as families with a (a) personal growth orientation, (b) conflict orientation, (c) conflict avoidance orientation, and (d) recreation avoidance orientation. Significant differences were found between the subtypes with regard to the family climate variables and satisfaction and coherence measures. Results demonstrated that different patterns of family climate characterized the two groups of fathers: In almost every cluster the measures of personal growth were lower for the fathers of disabled children.The authors would like to acknowledge the editorial assistance of Dee M.

Verb processing during sentence comprehension: Contextual impenetrability

This paper examines verb processing during sentence comprehension. We describe two experiments that assess the interaction between verb complexity and the structural information contained in a sentence. Verb complexity is defined in terms of a verb's possible argument structure arrangements—linguistic information arrayed against a verb's entry in the mental lexicon. Normal subjects had to perform a secondary task presented in the immediate vicinity of the verb while listening to a sentence for meaning. Reaction times to this secondary task show that all of a verb's possible argument structures are momentarily and exhaustively activated in the vicinity of the verb, even in sentences that are structurally biased toward one particular argument structure. We thus argue that verb processing in sentences involves a contextually impenetrable subcomponent of the language comprehension system.Program in Linguistics and Cognitive Science, Department of Psychology, Brandeis University.
