Interruption of phonological coding in conduction aphasia

A case study of conduction aphasia, investigating single word repetition, phonological coding, and short-term memory, is reported. Evidence from intact adults suggests that repetition can occur through either a lexical route or a direct auditory-articulatory link. For this conduction aphasic, E.A., the direct link was impaired, although the lexical route could be used to produce accurate single word repetition. Several experiments demonstrated a significant impairment in the generation and maintenance of an abstract phonological code. The consequences of a disruption of phonological coding on speech perception and on verbal short-term memory are discussed.     

Cerebral lateralization of visual stimulus recognition in stutterers and fluent speakers

Cerebral lateralization of stutterers and nonstutterers was assessed in terms of choice reaction times to stimuli presented to either the left or right visual hemifield on letter recognition and figure recognition tasks. Reaction times on both tasks were determined before and after a behavioral speech therapy program. Stutterers demonstrated a significant reduction in mean reaction times in the letter recognition task over the course of the therapy program. This change differed significantly from that obtained from stutterers in the figure recognition task. The stutterers' responses were in contrast to the responses of the nonstutterers, who showed no reduction in mean reaction times for the letter or figure recognition tasks. The results were discussed in terms of alterations in aspects of central nervous system processing as a result of participation in the behavioral speech therapy.     

The effect of reinforcement for global or analytic strategies on the performance of reflective and impulsive children

Second and sixth grade impulsive and reflective children were administered a conceptual style task with a modification that children were reinforced specifically for either global or analytic processing. Results indicated that both reflectives and impulsives were capable of offering either a global or analytic hypothesis under appropriate reinforcement. Results were interpreted as indicating the relevance of motivational factors to reflection/impulsivity and cognitive style.     

Factor comparison of two Minnesota Multiphasic Personality Inventory short forms

A sample of 315 valid Minnesota Multiphasic Personality Inventory (MMPI) protocols were selected from inpatient files and scored for both the MMPI-168 and Faschingbauer Abbreviated MMPI short forms. Each short form was then factor-analyzed by a principal axis strategy with varimax rotation. The six factors extracted from each short form were then compared as to their similarity by use of the s index. This procedure showed five of the six factors in each short form as having a significant relationship of the pattern of salient variables they had in common with the complimentary factors of the other form. These data suggest that both short forms, though based on different construction methodologies, share the same underlying personality attributes. Future research is suggested to replicate these results and extend them to the full MMPI.     

Cerebral lateralization in bilinguals: Methodological issues

The literature on lateralization for language in bilinguals manifests two apparent contradictions. Some papers demonstrate differences in lateralization between bilinguals and monolinguals; others demonstrate none. In studies with exclusively bilingual subjects, some papers demonstrate differences between the lateralization for the two languages, while others demonstrate none. This paper discusses the range of methodological parameters which must be borne in mind when conducting or evaluating studies of lateralization for language in bilinguals. These include issues of subject selection, language and stimulus selection, testing procedures, data analysis, and interpretation of results.     

A perceptual comparison: Stuttering and nonstuttering children''s nonstuttered speech

Recently, perceptual evaluation of the nonstuttered speech of stutterers has received renewed research interest. To summarize, the majority of research on this subject reported the nonstuttered speech of adult stutterers was perceptually identifiable from that produced by normal speaking individuals. A continuation of this line of research would be to determine if the nonstuttered speech of children would be equally recognizable. The results of this investigation would indicate this is not the case. The implications of the sophisticated judge's inability to identify stuttering children based on nonstuttered speech are discussed.     

Cognitive complexity and the similarity-attraction paradigm

The study investigated the role of cognitive complexity as a moderator of the similarity-attraction relationship described by Byrne (1971). Subjects conducted face-to-face interviews with confederates who played roles as job applicants. Similarity-dissimilarity was manipulated by the confederate roles, as well as by the information given the subjects in accordance with the procedures described by Byrne (1971). The situation was viewed as one in which judgments were made about a complex, multidimensional stimulus. Information received about another person in an interview setting was viewed as consisting of different dimensions to be assessed by the perceiver. The hypothesis was tested and confirmed that cognitively complex judges were more likely than simple judges to perceive and evaluate similarity/dissimilarity in others. Thus, complex judges evaluated similar applicants more positively than dissimilar applicants, while no differences were found for simple judges. Cognitive complexity thus appears to moderate the “Law of Attraction” described by Byrne (1971).     

Sequential variables and the Kamin effect

The results of two experiments demonstrated that retention deficits occurred in a within-subjects design only when the intermediate interval test was either the first or second test of the retention of prior aversive conditioning experience; when two relearning tests preceded a 1-hr test, no performance deficits were observed. It was suggested that internal cues may serve as memory attributes of avoidance behavior during early stages of avoidance learning, while other stimuli may facilitate the retrieval of the memory of prior avoidance training with repeated testing.     

Self-disclosure reciprocity,liking and the deviant

Conflicting predictions were derived from social exchange theory about the role of social attraction and the reciprocity norm on mutual self-disclosure in dyadic relationships. Sixty-six female subjects were exposed to one of three levels of disclosure input: conventional-low disclosure, conventional-high disclosure, or devianthigh disclosure. In support of the reciprocity norm prediction, willingness to disclose personal information was a positive function of the amount of disclosure input from another person, regardless of the degree of liking for the initial discloser.
