Pictorial rehearsal

Subjects were presented with a sequence of picture-word items. The pictures were line drawings of common objects, and the words were the names of the objects. Half of the items were followed quickly by the next item, and the other half by a 15-sec “rehearsal interval.” The subjects were told to use these intervals to rehearse the item just presented, either by saying the word over and over to themselves or by maintaining the picture before the mind’s eye. There followed a test in which each item from the study list was cued with a fragment of either the picture or the name. Consistent with previous findings, identification was more probable for fragments of items that had been followed by a rehearsal interval. In addition, this advantage was found to be greater when the type of cue matched the mode of rehearsal that the subject had been instructed to adopt; there was in fact little, if any, advantage of rehearsal when cue and mode of rehearsal mismatched. This pattern of results suggests functionally distinct pictorial and verbal modes of rehearsal that serve not only to maintain information in conscious mind but also to build up memory proper.     

Differences that suggest female investment in,and male distance from,children

A factorial between subjects experiment was conducted with sex of respondent, level of success, sex of stimulus parent, and sex of stimulus child as the independent variables. Two hundred seventy-two undergraduates without parenting experience constituted the sample. The attributions made to explain parenting success/failure and the ratings made both of the child and the parent on the same 60 personality item were the dependent variables. Female respondents were not only especially success-oriented, but evidenced a view of parenting emphasizing deliberation and skill, whereas their male counterparts were comparatively more inclined to explain failure in terms of it being the child's fault and to overstate a child's meanness.This investigation was completed on the first author's NIMH traineeship (5 T01 MH-14473) for doctoral study. The authors are appreciative of the contributions of Professors Donn Byrne, Kay Deaux, and William Martin to the development of this study.     

Agreement between observers when the categories are not specified in advance

To test the agreement between two observers who categorize a number of objects when the categories have not been specified in advance, Brennan & Light (1974) developed a statistic A′ and suggested a normal approximation for its distribution. In this paper it is shown that this approximation is inadequate particularly when one, or both, of the observers place a fairly equal number of objects in all of their categories. A chi-squared approximation to the distribution of A′ is developed and is shown to work well in a variety of situations. The relative powers of A′ and the ordinary X² test for association are dependent on the type of ‘agreement between the observers’ that is assumed. However a simulation for a fairly general type of agreement indicates that the X² test is more powerful. As the X² test is also much easier to apply, it would seem preferable in most situations.     

Development of sex biases in children: 40 years later

Children in grades 2–10 (200 of each sex) assigned desirable and undesirable traits to girls or boys. Half the subjects had an additional option of both sexes. Children in all grades assigned more desirable traits to their own sex and more undesirable traits to the opposite sex, in line with Smith (1939). Both sexes became less positive toward their own sex and more positive toward the opposite sex with increasing age. This pattern also had characterized girls in Smith's study, whereas, boys had shown the opposite pattern. Beginning in the sixth grade, girls were more apt than boys to assign desirable traits to their own sex. Availability of the “both sexes” option decreased stereotyping, especially in girls.     

Depressed mood and environmental mastery as potential pathways linking family relationship quality and disease self-management for African Americans with hypertension

African Americans are at significantly greater risk of hypertension and worse cardiovascular outcomes than other racialized groups, yet hypertension intervention effects remain limited. Thus, it is necessary to understand the potential mechanisms whereby interventions may be more effectively targeted to improve health. Supported by prior research evidence and guided by the Biobehavioral Family Model, this study examined associations between family relationship quality, psychological wellbeing, and self-management behaviors for African Americans with hypertension. Data were pooled from three Midlife Development in the U.S. projects, resulting in a sample of 317 African Americans (63.4% female, M_age = 53.32) with self-reported high blood pressure in the past 12 months. We tested four cross-sectional multiple mediator models, with depressed mood and environmental mastery mediating associations between family strain and exercise, smoking, problematic alcohol use, and stress-eating. Environmental mastery mediated the association between greater family strain and decreased odds of achieving recommended exercise levels; greater odds of reporting problematic alcohol use; and greater stress-eating. Though family strain was associated with depressed mood in each model, this variable did not serve as an indirect pathway to self-management behaviors. Family strain, and the potential pathway identified via environmental mastery, may be a meaningful predictor of disease self-management for African Americans with hypertension. Longitudinal studies are needed to examine directionality and to support intervention trials for improving self-management and hypertension outcomes.     

Variation of the magnitude of the horizontal-vertical illusion with retinal eccentricity

The horizontal-vertical illusion was studied as a function of retinal eccentricity. It was found that the relation of illusion magnitude to vertical eccentricity is described by a U-shaped function with large amounts of reversed illusion for the more eccentric positions. Substantial effects due to horizontal eccentricity were also obtained, but these were not consistent across subjects. It is suggested that the flattening of the peripheral zones of the refracting surfaces of the eye may be involved in the variation of the illusion with retinal position, and that the astigmatic properties of the central portions of these surfaces may be a prime factor in the usual horizontal-vertical illusion.
