Brainstem auditory electrical response characteristics of stutterers and nonstutterers: A preliminary report

In the present study, eight adult male stutterers and nonstutterers showed no significant latency or amplitude differences in BSERs recorded in response to monaural and binaural clicks. However, significantly greater variance was found in the stutterers' group under the monaural stimulation condition at click rates of 12/sec and 5/sec. Left and right monaural waveforms were subtracted individually from the binaural waveform. The resultant binaural interaction difference traces were examined to determine auditory tract preference for binaural stimulation. While some subjects from both groups showed no auditory tract preference, it was found that the significant variance between groups for wave V latency was attributable to the subset of stutterers without auditory tract preference. This finding is interpreted as evidence of neurological differences in stutterers' auditory processing at the brainstem level.     

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.     

Thorndike's Legacy: Learning, Selection, And The Law Of Effect

This introduction to a symposium on the centennial of Edward L. Thorndike's 1898 monograph on animal intelligence briefly considers the origins of his law of effect and the influence of Darwin's selectionism. It also provides the background for an unfinished book review by William W. Cumming of a biography of Thorndike. The review places in historical context Thorndike's position both on psychology as a science of behavior and on the vocabulary of that science.     

Evolutionary Ethics: What Can We Learn From from the Past?

In this paper I look at the question of the derivation of ethics from evolutionary biology, and I do so by considering both historical attempts to make such a derivation and contemporary work.     

Applying an occupational classification to the work histories of young men and women

Holland's occupational classification was used to analyze the work histories of a national representative sample of young men and women ages 14 through 24. Hypotheses tested were concerned with the psychological orderliness of occupational changes, the relationship between occupational experiences and aspirations, and the relationship between consistent occupational codes and the stability of work histories. The analyses supported the usefulness of the occupational classification for organizing the work histories of both young men and young women. For both sexes, the classification reflected regular patterns of job changes. The category of a person's earlier job was an efficient predictor of a person's subsequent jobs; likewise, the category of a person's current job forecasted the category of his vocational aspiration. The consistency of an occupational code was also related to job stability for whites but not for blacks.     

Dependency and fault as determinants of helping

In a natural setting, helping was investigated as a function of a female requestor's dependency on the subject for help and whether or not she was at fault for her plight. Based on previous research and the hypothesized operation of two norms, it was predicted that the negligent requestor would be more likely to receive help than the victim of circumstance when her dependency was high, but would be less likely to receive help when her dependency was low. Randomly selected telephone subscribers received a “wrong number” telephone call from a stranded women motorist. The woman asked the subject to make a phone call for her; the dependent variable was whether the subject helped by making the call. Results were consistent with predictions. When dependency is high, the victim's negligence appears to operate as an indication of greater need, whereas when dependency is low, it seems to operate as a sign that the victim is less deserving of help. Results were discussed in relation to different social norms that may be activated as a function of the dependency of the requestor.     

Perceptual study of the speech of “successfully therapeutized” stutterers

The purpose of this investigation was to determine if the fluent speech of “successfully therapeutized” stutterers and a group of partially treated stutterers was perceptually different from the fluent speech of normal speaking subjects. Tape recorded speech samples of treated stutterers were obtained from leading exponents of (1) Van Riperian, (2) metronome-conditioned speech retraining, (3) delayed auditory feedback, (4) operant conditioning, (5) precision fluency shaping, and (6) “holistic” therapy programs. All forms of disfluency were edited out of these tapes. The remaining samples were then paired with matched fluent samples of normal talkers and presented to a group of 20 sophisticated judges. The judges were instructed to select from each paired speech sample presented to them the one produced by the stuttering subject. The results of the analyses of variance for correct identification of the stutterers showed that the partially treated stutterers, as well as each group of therapeutized stutterers, were identified at levels significantly above chance. This meant that the fluent speech of the partially and successfully treated stutterers was perceptibly different from the utterances of the normal speakers sampled. In addition, the analyses of variance also revealed that all stuttering groups had a significant severity factor. This finding indicated there was a significant difference between the severity subgroup in all the samples investigated. These results were discussed in terms of their clinical implications.     

Perceived coercion, resistance to persuasion, and the Type A behavior pattern

Three studies are reported, which tested the notion that persons possessing the Type A “coronary-prone” behavior pattern would be more susceptible to the experience of psychological reactance than would Type Bs, i.e., persons without that pattern. In Experiment 1, subjects exposed to a persuasive communication that was either low or high in coerciveness rated the degree of coercive intent behind the communication. Type As perceived greater coerciveness overall than Type Bs, a finding that was most reliable in the low coercion condition. In Experiment 2, subjects' postcommunication opinions were assessed, so that resistance to persuasion could be measured. A gender difference within Pattern A emerged from this study. Male Type As resisted the persuasion attempt to an equivalent degree whether it was low or high in coerciveness; female Type As displayed comparable resistance in the low coercion condition, but tended to be even more resistant in the high coercion condition. In contrast, both male and female Type Bs displayed persuasion in the low coercion condition, and resisted (to a degree comparable to Type As) in the high coercion condition. Experiment 3 further investigated resistance to persuasion among females, using a different issue for the persuasion attempt. Type A women again resisted more in the high coercion than the low coercion condition. Type B women displayed no evidence of resistance in either condition. Discussion centers on the observed gender difference and the possible theoretical importance of the notion that Type As perceive threat at lower objective levels than do Type Bs.     

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.
