Stimulus context and infant orientation discrimination

In three experiments, the effect of additional "contextual" elements on the discrimination of the orientation of linear and curvilinear segments was investigated with 4-month-old infants. In Experiment 1, paired visual matrices (one which contained some irregularity in orientation of internal elements, vs one which contained no irregularities) were presented. Infants detected irregular matrices significantly better than chance, but such detection was not aided by contextual elements. Discrimination of orientation in Experiment 2 was assessed with a paired-comparison familiarization-novelty paradigm. It was found that the addition of elements here significantly aided discrimination of linear segment orientation, but not curvilinear segment orientation. Experiment 3 investigated why this effect was not found for curvilinear segments; after equating the curvilinear stimuli to linear ones used in Experiment 2 with respect to the closedness of figure, discrimination of curvilinear orientation was observed.     

A comparison of three methods for scoring figure drawings

Figure drawings obtained from 758 white male medical students were scored using three different methods. Method I involved 16 different physical size measurements; Method II involved six separate sophistication of body concept ratings; and Method III involved 42 separate aspects of the drawings weighted in direct proportion to their relative frequency of occurrence in the sample studied (conventionality scoring). Separate factor analyses of the scores derived from each method revealed that Methods I and II each reflect only a single underlying factor, and that these factors are uncorrelated in the population studied. Method III yielded eight meaningful factors, each of which may be construed as an independent area of conventionality/deviancy. An overall conventionality/deviancy score was also derived. It is believed that these three methods of scoring capture most of the variance inherent in existing figure drawing scoring systems, but that use of all three is necessary for a comprehensive analysis.     

Discriminating between alcoholic and nonalcoholic blacks and whites on the MMPI

The purpose of the present study was to investigate the influence of race (black, white) on the MMPI performance of alcoholic and nonalcoholic inpatients. Subjects were 73 (27 black, 46 white) male alcoholic inpatients and 73 (27 black, 46 white) male nonalcoholic psychiatric inpatients. While black and white alcoholics failed to differ on the MMPI, white alcoholics presented as less disturbed and black alcoholics as less defensive and distressed, compared to their respective nonalcoholic counterparts. Furthermore, only white alcoholics were accurately identified by the MMPI 2-4/4-2 high-point pair combination and only white alcoholics achieved more high-point pairs containing Scale 4 relative to nonalcoholic controls.     

Attitude accessibility following a self-perception process

Self-perception processes have been postulated to occur only to the extent that initial attitudes are weak. The present research asked whether the outcome of such a process is a strengthening of the attitude in question. Two experiments investigated the accessibility of attitudes from memory following self-inference from behavior. Experiment 1 examined the consequence for attitude accessibility of reviewing and considering previously performed religious behaviors that were recent and primarily unmanded versus distant in time and "manded" in nature. Experiment 2 involved the performance of a new behavior that was either required or freely chosen. In each case, control subjects either did not review prior behaviors or did not perform a new behavior. In both experiments, attitude accessibility, as measured by the latency of response to attitudinal inquiries, was enhanced by the consideration or performance of unmanded behavior, but not by manded behavior. The relevance of this finding to issues regarding attitude-behavior consistency and attitudinal persistence is discussed.     

Task-related arousal of type A and type B persons: level of challenge and response specificity

To determine whether different levels of challenge had differential effects on the arousal levels of Type A and Type B persons, 30 Type A and 30 Type B male subjects worked on an intelligence test task (digits backwards recall) that was easy, moderately difficult, or extremely difficult. Arousal was measured in terms of systolic blood pressure, diastolic blood pressure, pulse rate, pulse volume, skin resistance, and subjective arousal. Results indicated that while working on the extremely difficult task, the Type A subjects evidenced reliably higher systolic blood pressure than did the Type B subjects (p = 0.1; difference = 7.52 mm of Hg) and that there were not reliable differences between the subjects in systolic blood pressure at other levels of challenge or on other measures of arousal.     

Withholding medical care for religious reasons

Stimulated by publicity over lawsuits involving parents of children who had died from deprivation of medical care, this article is a survey of the beliefs of religious groups that refuse medical care on theological grounds and the legal principles designed to protect children from such abuse. Particular attention is given to whether or not child-neglect laws that carve out exceptions for spiritual healing groups are constitutional under the establishment clause of the First Amendment. Very recent cases, including some still in progress, are used for illustration.     

Organization of needs in anorectic, bulimic, and obese college women

Central -peripheral organization of needs in women with eating disorders was investigated. Subjects included three clinical groups, totalling 50 female university students, identified as anorectic, bulimic and obese, and two nonclinical control groups, totalling 70 female students. The revised Picture Identification Test (PIT), which measures motivational aspects of Murray-based needs, was administered to all subjects. A new PIT measure, Cenper Index, showed significant differences in central-peripheral organization of needs between clinical and control groups, and among clinical eating disorder groups. The anorectic group differed most from groups on aggression and succorance needs; the bulimic group differed on abasement and defendance needs; and the obese group differed on dominance, exhibition, and gratitude needs.     

Problem-Solving Training as Prevention with College Students

Problem-solving processes play an important role within remedial and human effectiveness models of development. This article discusses the use of preventive problem-solving training with college students.     

Beliefs about and experiences with battering: Women and men in two populations

A questionnaire was developed to measure beliefs about and experiences with violence in the family. Two groups of persons in two different states who had attended conferences on battered women participated in this research. Of the 177 subjects (84% women, 16% men), none of the men had been battered, yet over one-third of the women had been; more older women reported having been adult battering victims than did younger women; the women had less formal education than the men; the women in the lower educational groups were more likely to have been battered and to report fear of becoming victims; and the social service workers reported little fear of battering.     

Perceived variability and symbol use: a common language-cognition interface in children and chimpanzees (Pan troglodytes)

Analysis of two chimpanzees' conversations with their teacher during a tool-use training task demonstrated that chimps use lexigrams, a humanly devised visual symbol system, selectively to encode perceived variability; that is, they generally used their symbols to differentiate alternative possibilities or to represent change or novelty in a situation. In contrast, they tended to leave unsaid what was unchanging, repetitive, or the unique possibility in a situation. Perceived variability influenced not only which symbols were selected but also utterance length: A single dimension of variability in a situation leads to single-lexigram utterances; multiple dimensions are associated with multi-lexigram utterances. This pattern of results indicates that the absence of formal grammatical structure in chimp language does not imply that utterances beyond one word in length are either rote strings or imitations. The chimps' tendency to mention the variable while leaving the constant or redundant unsaid is, moreover, strong support for the position that their use of a humanly devised symbol system is more than a series of conditioned responses.
