Cross-modal matching and association under sodium amytal

Anatomical and theoretical considerations, as well as experimental findings, have yielded conflicting points of view regarding the abilities of the right hemisphere in man to accomplish cross-modal transfer of information. Auditory—visual cross-modal matching (CMM) and association (CMA) abilities of the left and right hemisphere (LH and RH) were tested, using the Wada intracarotid sodium amytal technique. It was found that the RH performed slightly better on these tasks than the LH. These findings contrast with results of other techniques which indicate that the RH cannot perform CMM and CMA.     

Dichotic speech perception: A comparison between stuttering and nonstuttering children

A stop consonant-vowel dichotic listening task was administered to 90 right- handed boys, 30 in each age group of 5, 7, and 9 yr. Half in each group were stutterers, half nonstutterers. Two and a half times as many stutterers as nonstutterers were found to display either a left-ear advantage (LEA) or no ear advantage (NEA). This finding suggested a greater tendency on the part of stutterers, as opposed to nonstutterers, for reversed or bilateral representation of the auditory speech areas of the brain. In addition, both stutterers and nonstutterers displayed significant developmental increases in the number of times they were able to identify both dichotic speech stimuli, thereby supporting the hypothesis of an age-related increase in children's total information processing capacity. The results are discussed in terms of the differences between stutterers and nonstutterers with respect to the issues of motor representation, cognitive modes, and higher-order linguistic processes.     

Organizing factors in remembering and comprehending: A developmental analysis

This report describes an experiment that emphasizes: (a) the influence of organizing factors in remembering and comprehending and (b) the development of those skills that are related to the ability to organize. The analysis of the data was based on a theory of comprehension that emphasized a pair of interrelated processes, one providing for the construction of a schema or plan and the other for the semantic integration of items into the evolving plan. As predicted, adults perform more accurately with the paragraphs vs. the scrambled paragraphs and with the word lists as compared to the scrambled word lists. Accuracy with unrelated words is generally greater than with related words, a finding that is consistent with a reconstructive theory of remembering. The pattern of results for the 5th grade Ss is quite different: they perform more accurately with the scrambled paragraphs than with the paragraphs and somewhat more accurately with scrambled word lists rather than with word lists. These results were interpreted as evidence for a problem of control for the 5th grade Ss. We have assumed that the ability to process certain forms of information depends upon the ability to select and maintain an appropriate focus of attention. The results for these younger Ss suggest that their ability to file information into a schema as a filing system is compromised by the need to change or modify the filing system.     

Language and imitation in development

Noting the central role accorded imitation in the origins of symbolic functioning, language development, and identity formation, as well as its relationship to aspects of individuation, the authors have reviewed the problem of imitation from both cognitive developmental and psychoanalytic perspectives. They have specifically delineated piagetian views regarding the origins of imitation and traced its relationship to the emergence of language, while attempting to clarify various psychoanalytic formulations on this topic. This dual theoretical perspective is then reconsidered within the framework of the current empirical infancy literature. Pathological sequelae of imitation are also reviewed in relation to their impact upon ego formation and the process of socialization. Tracing a cognitive developmental line, the authors then discuss the relationship between imitation and the emergence of language; language is also considered as an important vehicle of communication which furthers and enhances ego development and object relations. The authors conclude with a partial integration of piagetian and psychoanalytic hypotheses regarding imitation and identity formation with the aim of stimulating further discussion on this topic.     

The impact of moral theories on cheating

This research series began as a test of an emotion-attribution approach to moral behavior. However, in the early studies, college students who read about morality were subsequently more likely to cheat on a vocabulary test than were control subjects who read materials irrelevant to morality. We hypothesized that resentment toward the test constructors interacted with the moral schemas activated by the reading task. To reduce resentment, in Study III the vocabulary test was presented as the experimenter's doctoral research. As predicted, compared to controls, those subjects who read about morality cheated less. Study IV was a quasi-experiment that confirmed the hypothesized resentment differences between Study III and the earlier studies. In Study V, while two groups read about morality, one group read an internal emotion-attribution passage and the other read an external version; less cheating was observed in the internal condition than in the external or control conditions. The results indicate that even when moral schemas are elicited under conditions favoring moral behavior, those schemas will lead to reduced cheating most effectively under conditions in which subjects attribute their emotional arousal to their own behavior rather than to external causes. Issues of moral schema activation and emotion-attribution in moral behavior are discussed.     

Computers in the training of inquiry

The era of microprocessors provides an opportunity for examination and restructuring of university-level education in psychology. Computers may aid in the development of environments based upon sustained and deepening inquiry on the part of students from their earliest contact with psychology. We have been developing a computerized system for the exercise of skills in psychological inquiry appropriate both as a teaching tool for beginning undergraduates and for the research of permanent and visiting professors. In this paper we discuss our philosophy, some aspects of the organizational and human factors problems involved, and issues of hardware and software design.     

Increased regional cerebral glucose metabolism and semantic memory performance in Alzheimer's disease: A pilot double blind transdermal nicotine positron emission tomography study

Nicotinic receptor dysfunction and impaired semantic memory occur early in Alzheimer's disease patients (AD). Previous research implied that nicotine's ability to enhance alertness, arousal, and cognition in a number of nonclinical populations was a function of its ability to stimulate CNS nicotinic cholinergic receptors. In this study it was hypothesized that transdermal administration of nicotine would increase both regional cerebral glucose metabolism (rCMRglc) and semantic memory (as assessed by verbal fluency). Two mild AD and two elderly controls underwent positron emission tomography scanning during a double blind nicotinic agonist verbal fluency challenge procedure. rCMRglc increases occurred in both AD patients, but not controls. In the two AD patients, verbal fluency scores increased by an average of 17%. One elderly control's verbal fluency increased, and the other decreased. These findings suggest that nicotine's effect on metabolism and verbal fluency is due to its ability to stimulate the cholinergic system.     

Role of Informal Integration in Career Advancement: Investigations in Plural and Multicultural Organizations and Implications for Diversity Valuation

The major question which this research examinedis whether informal integration is likely to result incareer advancement and perceived resources within twodifferent organizational contexts (plural and multicultural). Specifically, we examinedinteractions of race, gender, and organization type onthe above two outcome variables. In pluralorganizations, employees are expected to assimilate intothe dominant culture, while in multicultural organizations,cultural change for the individual and the organizationis reciprocal. Hypotheses were tested with a combinedsample of 101 men, 35 women, 29 persons of color, and 107 whites. Results indicated that,congruent with predictions, greater social integrationoccurred in an organizational context in which valuingdifferences was a priority. Further, the influence of informal integration on career advancement wasstill important even after controlling for suchvariables as age, organizational tenure, education, andhierarchical level within the organization. Implications of these findings for valuing diversity arediscussed.
