Documentary Bioethics: Visual Narratives for Generations X and Y

Narrative bioethics is primarily understood to involve storytelling through the use of literature. This article suggests that other forms of media are necessary to convey stories of an ethical nature to an audience broader than one being trained as medical professionals. "Documentary bioethics" is a manner to present and interpret stories of an ethical nature using forms of popular electronic media in a reality-based documentary style to society at large, specifically Generations X and Y.     

Mueller-Lyer illusion and size estimation performance in schizophrenics compared to normal controls

A size estimation (SE) paradigm and the Mueller-Lyer (ML) illusion were used to examine perceptual disturbances in schizophrenics. 35 reliably diagnosed (DSM III-R) schizophrenics were compared to 20 subjects with no history of psychiatric illness. Perceptual distortions found in previous studies of schizophrenics were only to a certain extent confirmed in the present results. More overestimators were found among the schizophrenics than among the normals on the SE task. The schizophrenics, first of all the chronic patients, also proved to be more prone to the Mueller-Lyer illusion. A reason why the very clear differences between schizophrenics and normals found in previous examinations were not confirmed in the present study, might be that a reliable diagnostic instrument was for the first time used in this kind of study.     

Noradrenaline loss and the disruption of between-CS stimulus generalisation effects in aversion learning

In stimulus blocking the previous conditioning to one stimulus, A, followed by conditioning to the compound stimulus, AB, results in less conditioning to the other stimulus, B. Three experiments were performed to study the effect of the prior pairing of a stimulus A (noisy bottle) with lithium chloride followed by stimulus AB (saccharin plus noisy bottle) and lithium chloride pairings upon the strength of the aversion to the target stimuls B (saccharin) in NA-depleted and control rats. The results obtained were not in keeping with a "blocking" explanation since enhancement, rather than blocking, of the saccharin aversion was obtained, and confirm several recent demonstrations of the "anti-blocking" effect from investigations using the conditioned suppression procedure. DSP4 treatment attenuated the aversion-enhancement ("anti-blocking") effects in all three experiments. The possibility that DSP4-induced noradrenaline depletions may cause some disruption of between-CS associations leading to a lesser higher order conditioning or stimulus generalisation is discussed and the present findings do add further evidence to the conclusion that noradrenaline is intimately involved in attentional processes.     

Interpreter and Spanish administration effects on the WISC performance of Mexican-American children

A study was conducted to ascertain whether the use of an interpreter and/or a regular examiner in administering the WISC would affect the test results of a group of Mexican-American children. A covariance analysis of the results indicated that the use of English in the administration of some subtests of the Verbal Scale and a Spanish administration of some scales of the performance test are likely to elicit optimum performance of Mexican-American children.     

Effects of methylphenidate (Ritalin) on selective attention in hyperactive children

This study investigated the effect of methylphenidate (Ritalin) on the selective attention of hyperactive children designated as favorable or adverse responders to stimulant medication. Using a type II incidental learning paradigm, it was found that children in the drug condition recalled more central and less incidental stimuli than those children in the placebo condition. While no differential effects on recall were found for responder type, methylphenidate did affect the spontaneous overt labeling of central stimuli by the favorable responder group. Results were interpreted in terms of the role of methylphenidate in narrowing the focus of attention. Implications for the classification of hyperactive children as favorable and adverse responders were also discussed.This paper is based on a master's thesis completed by the first author in the Department of Psychology, University of Guelph, under the supervision of the second author. The authors wish to thank J. Thomas Dalby for his assistance in the conducting of this experiment.     

The effects of unequal competence and sex on achievement and self-presentation

Female and male college students were divided into high ability and low ability groups on the basis of scores on a problem-solving task. In a second problem-solving session, they worked with a same- or opposite-sex partner whose performance they were accurately informed had been much more or much less competent than their own at the first session. The achievement of highly competent females was higher when their partner was a less competent female than a less competent male. The performance of less competent males and females was lower when their partner was a highly competent female rather than a highly competent male. Results suggested that self-presentation concerns aroused by sex of partner and relative ability can inhibit achievement.This article is based on the first author's master's thesis, submitted to Department of Educational Psychology at Pennsylvania State University. Parts of this study were presented at the American Psychological Association Convention, San Francisco, August 1977.

Differences in Supervisory Needs and Expectations by Trainee Experience,Cognitive Style,and Program Membership

In this study the authors examined relationships between trainees' cognitive style, program membership, amount of practicum experience, and needs and expectations for supervision. Participants were 57 trainees in three graduate programs at a midwestern university. All respondents completed the Myers-Briggs Type Indicator (MBTI; Myers & McCaulley, 1985), the trainee version of the Supervisor Perception Form (SPF-T; Heppner & Roehlke, 1984), and the Supervisory Needs subtest of the Counselor Development Questionnaire (CDQ-SN; Reising & Daniels, 1983). Results suggested that trainees' expectations and needs regarding the supervisory experience differed by amount of practicum experience, cognitive style, and program membership. Differences due to amount of experience were more prevalent than were those due to cognitive style or to program membership.     

Community health nurses' knowledge of, attitudes toward, and involvement with adolescent contraceptive services

A national sample of community health nurses were surveyed to assess their knowledge of, attitudes toward, and involvement with reproductive health services. Results indicated that slightly more than half of the nurses provided or administered contraceptive services to adolescents, although 73% worked in settings where contraceptive services were provided to adolescents. However, only 3.6% indicated that adolescents were their primary client population. The majority (64.3%) stated that they felt as prepared to work with adolescents as they did with adult clients. While 98% were aware that most adolescents are sexually active before seeking family planning services, a minority correctly answered questions about pregnancy and contraception among adolescents. Ninety-five percent agreed that contraceptives should be available to adolescents, and 90% agreed that parental consent should not be required for adolescents seeking contraceptive services. Yet only 21.5% were aware of the implications of the Adolescent Family Life Act.     

Naturalistic memory in learning-disabled and skilled readers

Three experiments compared learning-disabled and skilled readers' performance on naturalistic memory measures, as well as investigated the relationship between memory performance on everyday and laboratory tasks. In Experiment 1, the laboratory task (sentence span task) and everyday memory measures were correlated moderately for both ability groups. Compared to skilled readers, disabled readers performed poorly on the sentence span task, and were less likely than skilled readers to remember information related to common objects and consequential events. Disabled readers were also less likely to rely on external prompts to help them recall everyday information. Experiment 2 extended the previous findings to older subjects and found that the majority of significant correlations between the laboratory (word span task) and everyday memory tasks were isolated to disabled readers. When compared to chronological-age-matched subjects, disabled readers were inferior in recency performance on the laboratory (word span) and natural serial recall (e.g., recall of U.S. presidents) tasks. Experiment 3 showed that under conditions that facilitate item accessibility, ability group differences in recall were comparable. Taken together, the findings indicate that disabled readers' memory deficits are pervasive across naturalistic and laboratory measures at the younger age, but these deficits diminish for older students. Further, the deficits that occur at the older age are due to problems in accessing knowledge.     

Visual speech processing: Word-decoding and word-discrimination related to sentence-based speechreading and hearing-impairment

Two aspects of visual speech processing in speechreading (word decoding and word discrimination) were tested in a group of 24 normal hearing and a group of 20 hearing-impaired subjects. Word decoding and word discrimination performance were independent of factors related to the impairment, both in a quantitative and a qualitative sense. Decoding skill, but not discrimination skill, was associated with sentence-based speechreading. The results were interpreted such that, in order to represent a critical component process in sentence-based speechreading, the visual speech perception task must entail lexically induced processing as a task-demand. The theoretical status of the word decoding task as one operationalization of a speech decoding module was discussed (Fodor, 1983). An error analysis of performance in the word decoding/discrimination tasks suggested that the perception of heard stimuli, as well as the perception of lipped stimuli, were critically dependent on the same features; that is, the temporally initial phonetic segment of the word (cf. Marslen-Wilson, 1987). Implications for a theory of visual speech perception were discussed.
