Communication and language in severely deaf adolescents

One of the most important psychological effects of early severe or profound deafness is an impairment in natural language-processing ability, with a consequent reduction in communicative skill secondary to the sensory deficit. Prelingual damage blocks the development of certain sequential/syntactical skills necessary for the acquisition of normal linguistic competence. Educators of the deaf in the UK have typically attempted to improve linguistic ability using amplification and intensive training in lip-reading, but evidence from several psychological studies suggests that communication systems based upon manual signing are more productive of both linguistic and basic cognitive skills. This paper reports an experimental study of the communicative characteristics of both oral and total communication systems as a function of language structure. For almost all types of structure investigated, the total system was found to be the more effective method of communication.     

Factors in the Use of Oral Contraceptives by Young Women

This study examined the use of oral contraceptives in a sample of sexually active college women. The analytic approach employed was based on Fishbein's model for the prediction of behavior, which emphasizes perceived consequences and normative influences. It was found that each of these factors was significantly related to use of oral contraception, and that a stronger relationship was obtained when both components were combined. Results suggested that nonusers are more Likely to associate oral contraception with unhealthful consequences than are users, and that users believe employment of this method enhances their sexual satisfaction. It was also suggested that the opinions of these young women's partners and close friends, but not of their parents, are reflected in respondents' use of the pill. These results were compared with earlier findings on the correlates of intentions to use oral contraceptives, and applied implications were discussed.     

Contrasts in visual responsiveness and emotional arousal between rhesus monkeys raised with living and those raised with inanimate substitute mothers.

Rhesus monkeys were raised with dogs or inanimate surrogates in outdoor cages which provided them with complex, highly varied visual surroundings. Visual responsiveness to a variety of colored transparencies was investigated in three experiments, completed when the monkeys were between 18 and 30 mo old. Results indicated that the frequency and duration of looking at slides was significantly higher for dog-raised than for inanimate-surrogate-raised monkeys and that dog-raised monkeys were much more responsive to the novelty, complexity, ansal were obtained during the final experiment. Heart rate, vocalization, and changes in plasma cortisol were higher for monkeys raised with dogs. The frequency of most self-directed behaviors, however, was higher for monkeys raised with inanimate surrogates. Differences between rearing groups can only be the result of contrasts in attributes of the substitute mothers.     

Modulation of behavioral inhibition in appetitive extinction following manipulation of adrenal steroids in rats: implications for involvement of the hippocampus.

Corticosterone, the principal glucocorticoid in the rat, binds selectively to the CA1 pyramidal neurons of the hippocampus where the hormone has been demonstrated to exert a moderate chronic suppression of spontaneous activity. In the first experiment of the current study, the functional behavioral significance of this hormone--brain interaction was investigated in the extinction of an appetitive runway response in normal rats and those with lesions of the hippocampus. During extinction, half of the animals in each group were given daily subcutaneous injections of corticosterone. Whie the classical retardation effect of hippocampal lesions on appetitive extinction was replicated, hormone treatment was without effect in normal or hippocampally damaged subjects. The absence of a hormone effect in normals was primarily attributed to a saturated limited-binding system operating in the normal animal. Experiment 2 tested this notion, repeating the first experiment, with adrenal-ectomized (ADX), ADX + corticosterone replacement, and normal groups of animals. Adrenalectomy produced a striking facilitation of extinction which was speculated to be the result of a hyperactive inhibitory neural organ free from an inhibitory endocrine feedback. Corticosterone treatment normalized the progress of extinction in ADX animals, providing support for the afore-mentioned speculation. In the normal animal, it appears that a stress-induced surge in hormone level interacts with a limited-capacity neural binding to produce a transient dynamic range of behavioral disinhibition, perhaps promoting persistence during initial stages of frustrative nonreward in moderate stress tasks.     

The Effects of Sibling Death on the Surviving Child: A Family Perspective

The death of a child invariably affects the family, who in effect become survivors. Adaptations are made in order to secure a new family equilibrium attendant upon such a loss. Surviving siblings not infrequently become the focus of maneuvers unconsciously designed to alleviate guilt and control fate through silence and efforts to maintain silence, through substitution for the lost child, and through endowing the survivor-child with qualities of the deceased. Three types of clinically identifiable types of survivor-children are described. Families that emphasize silence and focus on guilt, families in which the child becomes incomparably precious, and families in which substitution and replacement provide the major theme lead respectively to the "haunted,""bound," and "resurrected" child.
These children share many features, as do their families, but there appears to be a connection between the family defensive maneuver and the specific consequences for a child of the bereaved family.     

Comparison of observational recordings in vivo, via mirror, and via television

Simultaneous observational recordings were made in vivo, via an observation mirror, and via closed circuit television. Three of nine observers had extensive experience recording behavior in vivo; three had extensive experience recording behavior via mirror; and three had extensive experience recording via television. Observers recorded nine categories of disruptive behavior for children in a special class setting. Frequencies of behavior recorded in vivo, via mirror, and via television differed significantly for only one category, vocalization. There were no significant main effects or interactions involving the observers' previous experience. Occurrence reliability coefficients computed within and between media demonstrated the similarity of observer agreement in all three media. Data collection procedures using an observational mirror or closed circuit television appear to be reasonable alternatives to in vivo observation in circumstances similar to those in the present study.     

A Study of the Relationship Between Family Interaction and Individual Symptomology Over Time

The study was designed to answer two questions: (a) Can a relationship over time between family interaction and individual symptomatology be demonstrated? (b) Can it be shown that changes in interaction have more influence on changes in the symptom than vice versa. Five interaction dimensions were taped in weekly, three-quarter hour sessions over 20 weeks in five families, each consisting of a mother-father-child triad who met certain criteria and had an encopretic child. The interaction dimension scores were abstracted weekly from these sessions by content analyses relying on various scales. The derived ratio scores were then related to the number of days the child soiled himself in the week preceding and following the interaction measurement. The relationship was assessed by Pearson correlation coefficients and step-wise multiple regression analyses adjusted to account for the possible inflationary effects of taking measures from the same subjects more than once. The results of the analyses answered both questions posed by the study in the affirmative, thus supporting the rationale underlying family therapy.     

Helping is not enough: Recipient's reactions to aid as a function of positive and negative information about the self

The present research investigated the effects of experimentally induced positive and negative feedback about the self on the recipient's subsequent reactions to aid. In line with a consistency prediction, subjects given positive feedback who later received aid had lower mood ratings and less favorable self-evaluations than those who were given positive feedback but no subsequent help. Conversely, subjects given negative feedback who later received aid had higher mood ratings and more positive self-evaluations than those who were given negative feedback but no subsequent help. Subjects' evaluations of another individual were characterized by aid main effects, which indicate that an other who helped was evaluated more favorably than an other who did not help. The conceptual and applied implications of these results are discussed.
