Bilateral language: Is the left hemisphere still dominant?

A 13-year-old left-handed boy with a left fronto-parietal vascular malformation evidenced bilateral symmetrical language representation at intracarotid amytal testing. Surgical resection of the parietal motor and frontal premotor area (sparing classical perisylvian language regions) for seizure control resulted in an acute aphasia. Language deficits were still apparent 3 months and to a lesser degree 1 year after surgery. This suggests that when language is bilateral and symmetrical, the left hemisphere may still be dominant or both hemispheres may be necessary to sustain full language competence. Explanations for atypical language localization within the left hemisphere are also discussed.     

Acoustic measures of stutterers'' speech following an intensive therapy program

Characteristics of consonant-vowel duration and vocal fundamental frequency (F₀) are reported for 12 school-age stuttering males. Subjects' speech was recorded pre- and post- therapy and at 2-mo follow-up. Mean F₀ and voice onset time values remained stable from pretherapy to 2-mo follow-up, and an increase of 12% vocalized time was maintained across all posttherapy samples. It is suggested that increases in speech fluency may not be accompanied by changes in fundamental timing gestures. Increased speech fluency may be accomplished through increases in vocalized time permitting adjustments in motor sequencing which accompany stuttering.     

The effects of sexual and/or aggressive film exposure on helping, hostility, and attitudes about the sexes

After viewing an aggressive, sexually aggressive, erotic heterosexual, or control film, 129 females and 135 males expressed their willingness to help and hostility toward the male or female experimenter. Males extended the least help to the experimenter following the aggressive film and expressed more positive affect than females. Erotophilic males expressed slightly less hostility toward a female than a male experimenter. Erotophiles expressed more positive attitudes toward women and toward men after viewing either the rape film shown by a male experimenter or the erotic film shown by a female experimenter, compared to erotophobes. Among erotophobes, these two experimental conditions generally produced the most negative effects on general attitudes about the sexes. Affective responses to sex variations in dominant status and to aggressivity were employed to provide explanations for these results.     

Abortion as a stigma: in the eyes of the beholder

The purpose of this study was to investigate social perceptions of a man who impregnated a woman and advised her to have an abortion, and those of a woman who had an abortion. Each subject rated one of four persons on a social distance measure: either a man involved in an abortion, a woman having had an abortion, a male control target, or a female control target. Both abortion targets were perceived less favorably than the control targets. The female abortion target was rejected more by male subjects than by female subjects, and the male abortion target was more rejected by females than by males. While holding permissive attitudes toward abortion was related to willingness to meet the female abortion target, restrictive attitudes toward abortion predicted willingness to meet the male abortion target. Variables related to stigmatization of the man were lack of identification, restrictive attitudes toward abortion, and perceived responsibility. Restrictive attitudes toward women's rights and roles in this society and restrictive attitudes toward abortion predicted stigmatization of the woman. It is suggested that shifting one's attention from characteristics of the stigmatized to observers' characteristics provides a useful perspective on the stigmatization process.     

Some neurolinguistic implications of prearticulatory editing in production

This paper argues that a complete model of language production must include a prearticulatory editing component. The function of this component is to monitor planned speech for deviations from the speaker's intention and repair any deviations that are found. It is claimed that adding such an editing component onto a production model fundamentally changes any account of aphasic symptoms using that model. As a case in point it is shown that E. M. Saffran's (1982, British Journal of Psychology, 73, 317-337) argument that agrammatic Broca's aphasia involves a deficit at the functional level of M. F. Garrett's (1975, in G. H. Bower (Ed.). The psychology of learning and motivation, New York: Academic Press) production model is no longer sound when prearticulatory editing processes are considered.     

Operant techniques used in stuttering therapy: A review

This article reviews research concerning the use of operant conditioning in stuttering therapy, and discusses the clinical implications of this literature. In order to be considered for this review, a report had to treat the findings of research specifically designed to use operant conditioning in the manipulation of speech disfluency. This body of experimental literature clearly indicates that operant management techniques can effectively reduce stuttering with punishment of disfluencies producing more notable results than reinforcement of fluent responses. Operant conditioning is an effective means of modifying stuttering behavior and should be more visible in terms of procedures used by speech therapists.     

Facial and autonomic manifestations of the dimensional structure of emotion

While subjects viewed and rated a series of 25 emotionally evocative slides, their heart rate and skin conductance were continuously monitored and their facial expressions were covertly videotaped. Judges subsequently viewed the videotapes and rated trial-by-trial the pleasantness and intensity of each subject's facial expressions. Both phasic skin conductance responding and judged facial intensity were curvilinearly related to self-reported pleasantness, with the largest responses occurring at both extremes of the self-report scale. In contrast, phasic cardiac reactions and judged facial pleasantness were linearly related to self-reported pleasantness; extreme pleasantness was accompanied by heart rate acceleration, and unpleasantness by cardiac deceleration. The results suggest that visceral information reflects the dimensions that underlie the organization of affects and, hence, may play a more important role in emotional experience than is assumed in a number of currently held theories of emotion.     

A comparison of syntax in young stutterers and nonstutterers

This study compares the syntactic structure of the spontaneous speech of a small group of stutterers and nonstutterers, using a method of constituent analysis. Speech samples were taped during play sessions with subjects, and the tapes were then transcribed and analyzed according to preselected constituent criteria. The stutterers were in the early stages of stuttering and had been diagnosed as stutterers by experienced clinicians. The method of analysis proved to be highly reliable. Differences were found in the number of complete clauses, the number of complex sentences, and in clause types between the two groups.     

Forgetting of recently acquired or recently reactivated memories

Four experiments compared the rates of forgetting following acquisition of a conditioned aversion and following a reactivation treatment given long after conditioning had been completed. The “reactivation treatment” consisted of a single presentation of the unconditioned stimulus, a procedure known to reinstate, following substantial forgetting, the behavior seen immediately after conditioning. It was first determined that the decrement in performance 1, 3, or 7 days later tended to be more rapid just after original conditioning than following a reactivation treatment given 27 days after conditioning. Subsequent experiments confirmed that the forgetting seen 3 or 7 days after original conditioning was in fact greater than forgetting 3 or 7 days after the reactivation treatment that had followed conditioning by 27 days; also, tests permitted rejection of the hypothesis that this effect could be attributed to nonassociative (systemic) consequences of the conditioning situation. Finally, tests indicated that retention 24 hr after a reactivation treatment was significantly better if the reactivation treatment followed conditioning by 27 days than if it were given just 3 min or 24 hr after conditioning. The central observation emerging from this study, that forgetting is more rapid following original learning than following a temporally remote reactivation treatment, was discussed in terms of potential interactions between the age (or accessibility) of a memory and processes that might be instigated by a reactivation treatment.
