Texture perceived with the fingers

Relative assessments of 10 attributes commonly used to describe the texture of liquids on skin were obtained for 14 liquids of widely varying rheological properties. The results were analyzed to show that these judgments can be predicted accurately from the assessments of just three attributes, smoothness, thinness, and warmth. Smoothness was found to be closely related to the forces of contact lubrication, and could be predicted from measurements of coefficients of friction. Thinness was found to be closely related to viscous forces, consistent with other predictions of assessments of thickness and spreadability. Warmth was not studied further. The results show how careful definition of the stimulus on the skin’s surface can sharply simplify the interpretation of the psychophysical experiment.     

Employment and health among married women with children

A sample of nearly 500 urban married women with children was used to evaluate the possible effect of outside-the-home employment on the mental and physical health of married mothers. Six measures of health were used, some drawn from interviews with the women, others from a medical examination. After controlling for ethnicity, education, and age of the women, the husband's occupation, number of children in the family, and length of time the woman has been married, it was found that wives who had been employed for more than a year were healthier than wives not employed outside the home and wives who had worked less than one year. Housewives who had never worked outside the home were healthier, on the whole, than wives who had been employed at some time in the past. Poor marital relationships and having no preschool age children seemed to increase the health advantage of long-term employed wives over those in the housewife categories. The occupational status of wife and husband did not seem to change these health differences very much.An earlier version of this paper was presented at the annual meeting of the Southwest Social Science Association, San Antonio, March 1975.

The interaction of locus of control expectancies and providing purpose on children's motivation

Children differing in locus of control orientation (internals, mediums, and externals' were administered an extended coding task following either a fictional rationale for the study (purpose incentive statement) or no purpose. As predicted, externals' performance under no purpose was significantly poorer and their rated interest in the task was significantly less favorable than those of internals. Also as predicted, these differences were nullified under the purpose incentive condition. The findings extend Lefcourt's (1967) suggestion that cue explication is important for externals to include external children, and support the position (Mischel, 1973; Rotter, 1975) that personality variables are increasingly important as a function of greater situational ambiguity. Implications of these findings for education and child-rearing are discussed.     

AIDS Knowledge,Attitudes, Beliefs,and Practices (KABP) in Two Caribbean Countries: A Comparative Analysis1

The present paper presents the results of AIDS Knowledge, Attitudes, Beliefs, and Practices (KABP) surveys conducted in two Caribbean countries: St. Vincent and St. Lucia. Despite religious, socioeconomic, and literacy differences between the two countries, their citizens are remarkably similar with respect to AIDS knowledge, attitudes, beliefs, and practices. The major differences between the two countries concern the perception of AIDS risk and the relative position of AIDS as a serious problem facing the country. These differences, however, appear unrelated to AIDS knowledge, sexual practices, or the likelihood of engaging in AIDS-protective behaviors. These findings question the role of perceived risk of AIDS as a determinant of AIDS-protective behaviors, and, more important, they question the utility of increasing perceived risk as a strategy in AIDS prevention programs.     

Idioms in sentences: Effects of frequency,literalness, and familiarity

This study investigated the relationship between subjective frequency of literal usage (literalness), subjective frequency of figurative usage (familiarity), and mean Kucera and Francis (1967) word frequency for idiom phrases. Kucera and Francis frequency was found to be independent of both familiarity and literalness. Furthermore, it was found that literalness, but not the Kucera and Francis frequency of the words in the phrase, affected reading time for literal uses of idioms. For figurative uses of idioms, familiarity and written frequency interacted. A model of idiom processing consistent with the current results and previous results is proposed. In addition, subjective familiarity and literalness norms are provided for 245 idioms.Portions of the normative study were based upon subjects in Schweigert and Cronk (1992).     

Aging and temporal discrimination of brief auditory intervals

Summary In a duration-discrimination experiment, young adults (mean age = 25.1), middle-aged adults (mean age = 45.5), and older adults (mean age = 64.6) were presented with two very brief auditorily marked intervals per trial, and their task was to decide which of the two was longer in duration. An adaptive psychophysical procedure was used to determine difference thresholds in relation to a constant standard interval of 50 ms. It was found that duration-discrimination performance was unaffected by age; all three age groups yielded a difference threshold of approximately 17 ms. It was concluded that the ability to discriminate durations of very brief auditory intervals appears to be based on an underlying timing mechanism that does not slow down with advancing adult age.     

Age rationing,the virtues,and wanting more life

The goal of this paper is to show that Callahan's reasons for withholding life extending care cannot be made out exclusively in terms of contemporary notions of distributive justice and fair allocation. I argue that by relying on a notion of justice which links the merit of the individual with the fairness of a social pattern of shares, Callahan imputes vice to the elderly as he denies them eligibility for life-prolonging care. Aristotle's doctrine of the mean is a useful tool for character evaluation. One can speak meaningfully of a proper disposition of a person of a certain type (an elderly person) with respect to the good of continued life. I claim that the mean of one's disposition with respect to the good of continued life would be relative to one's age group, and would be determined by that principle by which an elderly person of practical wisdom would determine it. This leads to very different conclusions than those drawn by Callahan.
