Cued recall in anterograde amnesia

After a single presentation of a word list, normal subjects exhibited better retention when prompted with semantic cues than with rhyme or letter cues. Alcoholic Korsakoff patients, patients receiving electroconvulsive therapy (ECT), and the patient N.A. exhibited impaired retention and, unlike control subjects, did not exhibit an advantage of semantic cues over letter and rhyme cues. Two experimental manipulations designed to equate the level of performance of amnesics and controls indicated that these amnesias could be understood as a reflection of weak memory strength that results from deficiencies in initial learning and retention. In addition, alcoholic Korsakoff patients appeared to have greater difficulty utilizing semantic cues than patients receiving ECT or patient N.A.     

Left-hemisphere language lateralization in bilinguals: use of the concurrent activities paradigm

Previous visual and auditory lateralization studies have demonstrated that the languages of bilinguals are lateralized to the left hemisphere to the same extent as in monolingual controls (C. Soares & F. Grosjean, 1981, Perception and Psychophysics, 29, 599-604; C. Soares, 1982, Neuropsychologia, 20, 653-659). The present study tested the same group of Portuguese-English bilinguals and a group of English-speaking monolinguals on a series of concurrent activity, or time-sharing, tasks. Greater levels of disruption in finger tapping with the right hand than with the left hand occurred during the performance of those tasks which required overt speech production, and this for both bilinguals and monolinguals. As in the previous studies, there were no lateralization differences across the bilinguals' two languages or between bilinguals and monolinguals. Thus, further evidence for equal levels of left-hemisphere dominance for language in bilinguals and monolinguals was provided by the use of the concurrent activities paradigm.     

A study of the “central life interests” and “work attachments” of male and female workers

This paper reports the results of a survey undertaken to investigate the overall central life interests and attachments to work of a sample of 1112 male and female employees of six Southern California manufacturing firms. The major conclusions suggested by this study are three. First, male employees have a slight tendency to be more work oriented in their overall central life interests than female employees. Second, female employees tend to be more strongly attached to extrinsic work features than male employees. Third, male-female differences in occupational status and perceived mobility opportunities probably account for gender differences in overall central life interests but these variables do not account for the tendency for women to be more strongly attached than men to extrinsic work features.     

Retrieval failure, rehearsal deficiency, and short-term memory loss in the aphasic adult

Studies show that aphasic patients typically are grossly impaired in short-term memory performance. Since aphasics generally experience difficulty in word retrieval, it is conceivable that short-term memory loss is partially the result of verbal rehearsal deficiency which, in turn, is caused by the word retrieval problem. This paper reports an experiment in which five aphasic adults were nonverbally to recall individualized lists of pictures they could easily name and lists of pictures they could not name. Final items in the two lists were recalled with equal accuracy; this was expected in that the recency effect usually reflects sensory rather than verbal storage. Initial items were recalled with greater accuracy than middle-list items in the nameable sets but not in the unnameable sets. This primacy effect suggests the aphasics rehearsed the nameable pictures, but both lists were recalled so poorly that rehearsal deficit was considered responsible for no more than a fraction of the aphasics' reduction in short-term memory.     

The social behavior of preschool children at different developmental levels: Effects of group composition

The social participation, constructiveness of play, and communicative interactions of 4- to 6-year-old developmentally delayed and nondelayed preschool children were compared under conditions in which children interacted in play groups homogeneous with respect to developmental level and in heterogeneous play groups. A within-subjects design was utilized to assess the relatively immediate effects of group composition. Data for both children and teachers were analyzed separately for each of four developmental level groups and across two time periods. Although numerous differences were obtained as a function of developmental level and time, the only significant effect of group composition on children was reduced inappropriate play by severely delayed youngsters while interacting in heterogeneous play groups. No detrimental effects of heterogeneous grouping were observed for children at any developmental level. These results were discussed in terms of their importance in evaluating the impact of programs that mainstream young children.     

On recognition and self: a discussion based on Nyāya,Mīmāṃsā and Buddhism

The phenomenon of recognition is a point of contention in the debate between the orthodox Hindus and Buddhists on whether the self (ātman) exists. The Hindus, including Naiyāyikas and Mīmā?sakas, argue that recognition evidences the existence of the self, while Buddhist philosopher ?āntarak?ita maintains that there is no self and recognition should be explained in another way. This article examined two disputes, focusing on the two subsidiary aspects of a recognition: memory and self-recognition. For Hindus, it is the existence of the self that makes memory and self-recognition possible. For Buddhists, it is due to the phenomena of memories and self-recognitions that people postulate the existence of the self. I argue that Buddhist explanation of memory is more acceptable, while their debates on self-recognition should be considered as a tie.     

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.     

Effects of positive and negative adult-child interactions on children's social preference

The effects of positive and negative interactions on children's performance and preferences for the adults associated with each type of interaction were studied. Five children served as subjects during daily sessions in which each of three adults followed prescribed patterns of social interaction. One adult (positive) dispensed positive comments contingent upon either color-sorting or completion of arithmetic problems; a second adult (negative) mildly reprimanded the child for off-task behavior; and the third adult (extinction or nonreactive) said nothing to the child when he was present. Following each session the three adults reentered and the child chose one of them for an additional period of interaction. Three response measures (frequency, latency, and percent of time on-task) and children's adult preferences were obtained daily. The negative adult affected the most task behavior and had strongest stimulus control; the positive adult, though exerting little control over children's behavior, was the most preferred. Children's adult preferences were not specific to the task setting, but were observed across a variety of contexts.
