Multiple effects of visual format on TV news learning

Two experiments were conducted on edited TV newscast sequences to clarify effects of film accompaniment on learning from heard news text. In Experiment 1,150 British subjects viewed a sequence with either film format throughout or alternating film and ‘talking head’ format between items. Those items that were presented by ‘talking heads’ in the mixed sequence were learned better with film format, in which the heard text was accompanied by appropriate moving pictures. However, no effect of uniform context was found on the remaining items. In Experiment 2, 91 German subjects viewed one of four versions of a bulletin, one with ‘talking head’, one with film throughout, the other two having complementary mixed-format patterns. Besides confirming a beneficial effect of film presentation over ‘talking head’ which accords with the findings of all studies of learning from material in the form of national network newscasts, the results showed an impairing effect of uniform visual format. This can explain ‘contradictory’ findings, notably with atypical test material.     

Perception of rate-altered sentential approximations by normal and aphasic children.

25 4-word, first, and second-order sentential approximations were presented to 18 aphasic and 18 normal children. The material was taped and altered to represent 5 speaking rates: 140 (normal); 75 and 105 (expanded); and 180 and 205 (compressed) words per minute. Order of presentation was randomized. The major difference between the children was that the second-order material was perceived best by normals regardless of rate, while the aphasics showed this preference only at the normal rate.     

Paired-associate learning by normal children and retardates with relevant redundant compound stimuli

During daily sessions four first-grade boys each played a two-choice marble dropping game. When one colored light was presented a plain token was dispensed as soon as S dropped a marble, and when another light was on a token with a hole in its center was delivered. During choice trials that were interspersed among single-color trials S had to choose one of the two different colored holes. At the end of each session S traded tokens with holes for pennies and then turned in the remaining plain tokens which were not exchanged for money. After S had developed a preference for the response that earned the tokens with holes (tokens that were backed up with pennies) E instructed S to try to get as many plain tokens (unexchangeable tokens) as he could. All Ss immediately switched to the response that earned unexchangeable tokens but as soon as E left they returned to choosing the backed up response. When the adult reentered, Ss again chose to work for unexchangeable tokens. Two different Es (male and female) served and the instructions of each were effective in controlling responding as long as the adult was present, except for one S who did not respond to one E, but did respond as described for the other.     

Person-Placement Congruence: A Framework for Vocational Counselors

A common guideline for vocational counseling is the rule requiring congruence between a man and his job. The issue of person-placement congruence was studied utilizing 159 patients referred for vocational rehabilitation to the Mental Health and Manpower Project from the Fort Logan Mental Health Center. A 13-item scale devised by project research staff and completed by vocational counselors was shown to predict later job success. By separating the scale into two categories, those items dealing with abilities and those related to needs, it was possible to predict the nature of job termination, i.e., quit or was fired. There was demonstrated considerable validity for the man-job fit approach to counseling, and this research served as an initial step toward detailing this rather simple rule.     

ECOLOGY,CULTURE AND PSYCHOLOGICAL DIFFERENTIATION

A model which examined interrelationships among ecological setting, cultural adaptation and psychological differentiation was proposed. Details of each element of the model were discussed, and behavioural predictions were made. Specifically, hunters and gatherers, who were migratory and low in population density and food accumulation were expected to exhibit high levels of psychological differentiation in perceptual, social and affective areas of psychological differentiation. Conversely, sedentary peoples who were higher in population density and food accumulation were expected to exhibit lower levels of differentiation, while those peoples who were ecologically intermediate were expected to exhibit moderate levels. Sampling in Amerindian communities, and comparing these new data to previous African, Australian, and Eskimo data, led to the conclusion that higher levels of differentiation in perceptual, social and affective domains do indeed characterize hunters and gatherers. However, such differences within a single culture area were minimal. An examination of the cross-cultural stability of the concept of psychological differentiation suggested greatest internal consistency for hunters and gatherers, and less for sedentary peoples; constant relationships with socialization emphases were found, while variations in sex differences were related to features of socio-cultural stratification.     

Breast cancer representations in Canadian news media: a critical discourse analysis of meanings and the implications for identity

Despite the importance of critical media work, much is to be learned about breast cancer representations within media discourses and the implications for women’s identity construction. Building on research from Australia from a discursive perspective, this article used an eclectic approach to critical discourse analysis to explore the cultural construction of breast cancer in 25 detailed stories within Canada’s two national newspapers, The Globe and Mail and the National Post. Ten images accompanying stories and 17 advertisements/public service announcements were also analyzed to contextualize discourses and subject positions/identities within the stories. Analysis of this media affords the unique opportunity to explore taken for granted assumptions and prevailing meanings about breast cancer and the implications for subjectivity. Two primary discourses were identified: a discourse of biomedicine and a discourse of healthism. Subject positions identified included “breast cancer survivor,” “the good consumer,” and the “medical expert.” The psychological, social, political, and health promotion implications are discussed.     

PREFERENCE FOR A STIMULUS THAT FOLLOWS A RELATIVELY AVERSIVE EVENT: CONTRAST OR DELAY REDUCTION?

Several types of contrast effects have been identified including incentive contrast, anticipatory contrast, and behavioral contrast. Clement, Feltus, Kaiser, and Zentall (2000) proposed a type of contrast that appears to be different from these others and called it within-trial contrast. In this form of contrast the relative value of a reinforcer depends on the events that occur immediately prior to the reinforcer. Reinforcers that follow relatively aversive events are preferred over those that follow less aversive events. In many cases the delay reduction hypothesis proposed by Fantino (1969) also can account for such effects. The current experiments provide a direct test of the delay reduction and contrast hypotheses by manipulating the schedule of reinforcement while holding trial duration constant. In Experiment 1, preference for fixed-interval (FI) versus differential-reinforcement-of-other-behavior (DRO) schedules of reinforcement was assessed. Some pigeons preferred one schedule over the other while others demonstrated a position (side) preference. Thus, no systematic preference was found. In Experiment 2, a simultaneous color discrimination followed the FI or DRO schedule, and following training, preference was assessed by presenting the two positive stimuli simultaneously. Consistent with the contrast hypothesis, pigeons showed a significant preference for the positive stimulus that in training had followed their less preferred schedule.     

Preventive intervention with infants and families: The NBAS model

A model for preventive intervention based on the use of the Neonatal Behavioral Assessment Scale (NBAS) is presented, and the conceptual framework underlying this approach is made explicit. The approach is based on the assumption that the neonatal period presents clinicians with a unique opportunity to influence parent-infant relations positively from the beginning. It is argued that especially under conditions of stress, this infant-centered but family-focused form of intervention can serve to prevent the compounding of problems that may occur when the caregiving environment is unable to adjust to the needs of the young infant. The aim of the NBAS-based approach is to sensitize parents to the communication cues and the unique adaptive capacities of their infants. It is the individualized nature of the NBAS-based approach that places it outside the domain of main-effects treatment modalities and renders it responsive to the particular needs of individual infants and their families. The model of intervention described herein is based on the development of a supportive therapeutic relationship between clinicians and parents and as such may serve as the first stage in a comprehensive follow-up program of support for infants and families. Guidelines for clinicians using the NBAS in clinical settings that follow from these assumptions are provided.
