Hemispheric differences for verbal and nonverbal stimuli in Japanese- and English-speaking subjects assessed by Tsunoda's method

This investigation compared the performance of Japanese- and English-speaking subjects on T. Tsunoda's DAF key-tapping task, which he purports assesses cerebral dominance for language (1975, Brain and Language, 2, 152–170). Twenty-three native speakers of Japanese and 23 English-speaking subjects were employed in this study. Each subject was administered the DAF key-tapping task utilizing the vowel /a/ and a 1000-Hz pure tone. The results revealed an effect of intensity, whereby an increase in DAF/SAF ratios resulted in an increase in performance disruption. No differences were observed between the two language groups, ears, or between the 1000-Hz pure tone and the vowel /a/. Only 15.5% of the subjects showed the hypothesized right ear advantage for the tone when subjected to an analysis similar to Tsunoda's. All other subjects revealed variable degrees of advantage to either ear, to the same ear, or to to neither ear. It was concluded that no significant functional auditory asymmetry was observed for either group, suggesting that the DAF key-tapping task may not be a sensitive procedure to determine cerebral dominance for language among normals.     

Differential methods of causal attributions for strangers vs acquaintances

Previous research has demonstrated that people are more likely to attribute a stranger's behavior to external causes if that behavior is common in a given population than if it is relatively unique (the consensus rule). It was proposed in the present paper that another and perhaps simpler rule is available for causal attributions for an acquaintance's behavior, such that more external attributions are made as the behavior becomes increasingly inconsistent with extant impressions of the target (the goodness-of-fit rule). It was found that the goodness-of-fitrule, but not the consensus rule, was used in the attribution of causality for acquaintances when the behavior could be made to fit with extant impressions. When the behavior was completely inconsistent with extant impressions, both consensus and goodness-of-fit rules were used, such that the most external attributions were made in the poor fit/high consensus condition.     

The “feminine mystique” in male-dominated jobs: A comparison of attitudes and background factors of women in male-dominated versus female-dominated jobs

This paper examines various background factors plus success and work-related atttudes of 324 women as aggregated into one of three groups: those women working in male-dominated jobs, those in female-dominated jobs, and those in relatively sex-ratio balanced jobs. Overall results show that women holding male-dominated jobs are more likely to be older, better educated, have fathers with higher educational levels, and are more likely to be childless as compared to women in female-dominated jobs. Holding age and education constant, women in male-dominated jobs usually rated definitions of success as more important to their feelings of well-being than did women in female-dominated jobs. With these same constants, there were few differences in work attitudes among the three groups, but contrary to expectations, women in female-dominated jobs rated the importance of their work higher than did women in male-dominated jobs. The variables best predicting whether a woman held a male-dominated job were college attainment, problems related to sex discrimination, the age of the participant, her feelings toward achieving a very high salary, her feelings of the importance of her work, and her feelings about becoming an authority in her job.     

An examination of encoding and retrieval processes in reading disabled children

A choice reaction time experiment was performed in order to assess the information processing characteristics of 12-year-old reading disabled children. Eight reading disabled children were compared to a sample of nondisabled readers. The stimuli consisted of consonants presented in three memory load conditions. A Stimulus Quality manipulation was included in the design in order to assess the encoding process. The results of the research indicated that the rate of encoding differed between disabled and nondisabled readers. In addition, support for the hypothesis that disabled and nondisabled readers do not differ in terms of central processes was also obtained.     

Quality of text recall as a function of children's classroom competence

This study demonstrated that the manner in which children, as students, chose to devise their recall was a function of the type of response register they maintained with their teachers. Students (mean C.A. = 10.4 years) who used an Imitative Response Register recalled significantly more referential propositions than students using either a Contingent or Noncontingent Response Register. In this sense, students employing an Imitative Response Register were more likely to reproduce text than the other Register Groups. Students (mean C.A. = 10.3 years) who used a Noncontingent Response Register recalled significantly more pragmatic inference propositions, i.e., either elaboration or distortion inference propositions, than students using either Imitative or Contingent Response Registers. In this sense, students employing a Noncontingent Response Register were more likely to embellish text than the other two groups. Finally, students (mean C.A. = 10.6 years) who used a Contingent Response Register recalled significantly more text-structured propositions, i.e., propositional and enabling inference propositions, than students using either Imitative or Noncontingent Response Registers. In this sense, students employing a Contingent Response Register were more likely to reconstruct text than the other two groups. These findings are discussed in terms of a classroom competence model of student behaviors.     

The effect of punishment on a factor I stuttering behavior

On each of five days the subject of this experiment read aloud different material during an 18-min A₁ (base rate), B (experimental), and A₂ (extinction) period. No stimulation was delivered during the first three days. On the fourth day, the nonsense word “norg” was presented noncontingently during the experimental period. There was no statistically significant difference between the A₁ and B periods on any of these four days. On day five, “wrong” was made contingent on Factor I prolongations during the experimental period. As a result, there was a statistically significant increase in their frequency. When the response consequence was removed in the A₂ priod, there was a reliable reduction in prolongations and the frequency closely approximated that found in the A₁ period. These data suggest that response-contingent negative stimulation is contraindicated as a clinical tactic for use with Factor I prolongations. It not only failed to suppress them, it increased their frequency.     

The relevance of DAF-induced speech disruption to the understanding of stuttering

The literature on delayed auditory feedback (DAF) repeatedly makes reference to the occurence of disfluencies under DAF in nonstutterers. However, no attempt has been made to determine the relative frequency of occurence of various types of disfluencies in nonstutterers under DAF. The present study investigated the frequency of occurence of various types of disfluencies in normal-speaking subjects in five successive oral readings under DAF. Twenty-four young adults read aloud a prose passage five times successively under 200 msec of bilateral DAF. Measures of the frequency of different types of disfluencies, locus of occurence of disfluencies in the speech sample, adaptation and consistency indicate that DAF-induced disfluencies are remarkably similar to those found in stuttering. It is suggested that DAF and stuttering disrupt speech at approximately the same “level” along the speech production process, possibly at the prosodic level.     

Stuttering adaptation under distributed and massed conditions

An identical-subject-repeated-measures design, involving two counterbalanced conditions, was employed to investigate adaptation when the presentation of a 100-word list is distributed and when it is massed. In Condition I, the entire list was read aloud during each of five successive trials. Since a specific word reoccurred only after all of the others were displayed, the presentation may be said to be distributed. In contrast, the Condition II presentation was massed. Only after a word was read five times was the next one presented. The results indicate that significant adaptation occurred in both conditions. However, adaptation plateaued in the distributed condition. This was not the case when massing was employed. The among-condition analyses revealed that significantly more adaptation occurred in the massed than in the distributed condition.
