Bogus physiological feedback and response thresholds of Repressers and Sensitizers

Repressers and Sensitizers viewed tachistoscopically presented TAT transparencies under conditions of high and low bogus physiological feedback. As predicted, during high bogus physiological feedback, Repressers showed a significant increase and Sensitizers showed a significant decrease in response thresholds. These results serve to extend the validity of bogus physiological feedback procedures in the analog investigation of emotion and offer theoretical implications relevant to the areas of personality, emotion, psychophysiology, and psychopathology.     

Clinician attitudes toward stuttering in the United States and Great Britain: A cross-cultural study

The attitudes toward stutterers and stuttering of 702 speech-language clinicians in the United States and Great Britain were studied. Three hundred seventy-one clinicians from six states in the U.S. and 331 clinicians from England and Wales completed the Clinician Attitudes Toward Stuttering (CATS) Inventory. Results of the study were analyzed in terms of differences and similarities in attitudes between the two groups with respect to the etiology of stuttering, early intervention, the effectiveness of stuttering therapies, various therapy techniques, stutterers and their personality, parents of stutterers, clinicians, and reactions of others to stutterers.     

Cognitive and motivational determinants of children's humor responses

Cognitive and motivational influences on children's humor responses were examined. Forty-eight Caucasian children from three economically heterogeneous schools were tested. Equal numbers of middle SES and lower SES boys and girls from kindergarten and third grade were shown 12 aggression and dependency cartoons of different difficulty levels. Three responses to each cartoon were recorded: mirth, funniness rating, and comprehension score. Results support aspects of both psychodynamic and cognitive theories of humor response. All children preferred aggressive themes to dependency themes, and third graders especially showed attenuated response to dependency cartoons. Funniness ratings decreased as difficulty levels increased. IQ, as assessed by the Peabody Picture Vocabulary Test-R, was positively related to humor. Mirth responses and funniness ratings increased as comprehension increased.     

Acoustic cues for the perception of place of articulation in aphasia

Two experiments assessed the abilities of aphasic patients and nonaphasic controls to perceive place of articulation in stop consonants. Experiment I explored labeling and discrimination of [ba, da, ga] continua varying in formant transitions with or without an appropriate burst onset appended to the transitions. Results showed general difficulty in perceiving place of articulation for the aphasic patients. Regardless of diagnostic category or auditory language comprehension score, discrimination ability was independent of labeling ability, and discrimination functions were similar to normals even in the context of failure to reliably label the stimuli. Further there was less variability in performance for stimuli with bursts than without bursts. Experiment II measured the effects of lengthening the formant transitions on perception of place of articulation in stop consonants and on the perception of auditory analogs to the speech stimuli. Lengthening the transitions failed to improve performance for either the speech or nonspeech stimuli, and in some cases, reduced performance level. No correlation was observed between the patient's ability to perceive the speech and nonspeech stimuli.     

Parent's report of stress and articulation oscillation as factors in a preschooler's dysfluencies

Recently, one focus of research on dysfluency and stuttering seems to be on the preschooler. One goal of such research should be to determine what factors in the child's language system and what factors in the social environment may put the child at risk for developing dysfluencies and stuttering. The following is a parent's account of the occurrence of dysfluencies in a preschooler. Emphasis is on a language phenomenon that might be labeled “articulation oscillation” and on apparent social environmental stress.     

Is it just reading?: Comments on the papers by Mann,Morrison, and Wolford and Fowler

Comments on the stimulating papers by V. A. Mann (Reading skill and language skill. Developmental Review, 1984, 4, 1–15), F. Morrison (Reading disability: A problem in rule learning and word decoding. Developmental Review, 1984, 4, 36–47), and G. Wolford and C. A. Fowler (Differential use of partial information by good and poor readers. Developmental Review, 1984, 4, 16–35) come under four headings. First, their differences with respect to the organizing themes are identified. Second, the central difficulty, for theories of reading disability, posed by the high correlation between reading and IQ, and ways of dealing with this difficulty, are discussed. In the third and fourth sections, comments on the individual papers and a summary of the main lessons to be learned from this collection are presented.     

The genetic context of perceptual imprinting: Canalization by stimulus preference

Recent data from various sources converge in pointing to constitutional constraints and genetic influences in behavioral development. What are the mechanisms that mediate such constraints and influences? Are they expressed through mechanisms of behavior acquisition and learning? Or are they expressed through genetically determined perceptual capacities and response propensities that guide behavior along species-typical and ontogenetically adaptive developmental trajectories? These alternatives are examined in the context of genetically and environmentally manipulated stimulus preferences and perceptual imprinting in Japanese quail chicks (Coturnix coturnix japonica). Data indicate that the genotype is a source of variation in unconditional stimulus preferences and that there are inhibitory and facilitative interactions between different unconditional preferences and also between unconditional and acquired preferences. Variations in stimulus-specific and stimulus-general learning may guide behavioral development in ways that are genetically preadapted, yet individually variable, and ontogenetically adaptive. Interpretation of data favors a synthesis of earlier psychological and biological concepts of canalization.     

Response probability and similarity of retrieved response tendencies as determinants of response suppression difficulty

The primary objective of this study was to test the validity of the here labelled ‘suppression-time’ assumption which contends that the more difficult the response suppression operation, the longer the time required for its successful implementation. A secondary interest addressed the possibility that output suppression difficulty would be influenced by the level of response-response (R-R) compatibility existing between retrieved response tendencies. Two basic requirements confronted subjects within an experimental session: (a) dual-initiation (Dual-I) of paired arm movements, (b) initiation/suppression (I/S) of retrieved outputs, the irrelevant response being suppressed, the relevant output initiated. RT(I/S) magnitude and failure-to-inhibit error frequency increased as response probability increased, thereby providing support for the ‘suppression-time’ assumption. But R-R compatibility degree variations, when realized, did not consistently affect response suppression difficulty.     

Recognition and discrimination of emotional faces and pictures

In order to learn whether patients with right-hemisphere disease (RHD) had a deficit in their ability to discriminate and comprehend emotional faces and pictures, we studied nine patients with RHD, nine patients with left-hemisphere disease (LHD), and nine controls. The subjects were presented with six picture tests that comprised either emotional faces or emotional scenes. Their task was either to denote (name or choose) an emotion or to discriminate (same, different) between two faces or emotions. Patients with RHD performed significantly worse than subjects with LHD when asked to discriminate between faces, to discriminate between emotional faces, and to name emotional scenes. There was also a trend for the RHD group to be more impaired than the LHD group when asked to name the emotional face or choose the emotional face. Except for the facial and emotional discrimination tests, the LHD patients also performed worse than controls.
