Some hypotheses concerning the evolution of polysemous words

The evolution of polysemous words is examined in three studies. Study 1 indicates that older words are more polysemous than recent words, and that frequently used words are more polysemous than infrequently used words. These effects were replicated, controlling for word concreteness (Study 2) and evaluation (Study 3), using two other samples of words. If words evolve additional meanings through metaphor (MacCormac, 1985), then variables (such as concreteness and evaluation) that play a role in metaphor may mediate the evolution of polysemy. The correlation between concreteness and polysemy was negligible (Study 2). As hypothesized, evaluation is a significant predictor of polysemy: Negative words are more polysemous than positive words, and relatively neutral words are more polysemous than evaluatively extreme words. These findings are consistent with the notion that polysemous words evolve, in part, through metaphor.     

Efficacy of behavioral management and patient education on vascular access cleansing compliance in hemodialysis patients

Compared four treatment conditions to test their ability to enhance compliance with vascular access cleansing (VAC) procedures in a group of 56 hemodialysis patients. The conditions were patient education, behavioral management with monetary incentive, patient education/behavioral management, and attention control. Behavioral observers rated VAC behavior at pretreatment, posttreatment 1-month follow-up, and 1-year follow-up. Knowledge of VAC procedures was also assessed via a questionnaire at pretreatment and posttreatment. Data were analyzed using repeated-measures multivariate analyses of variance. Results indicated that the patients in the education/behavioral, behavioral, and education groups gave significantly more correct answers on our VAC knowledge questionnaires at posttreatment than did patients in the attention control group. Further, patients in the education/behavioral and behavioral groups completed significantly more VAC steps at posttreatment and 1-month follow-up than did patients in the education group and in the attention control group. Differences were not maintained at 1-year follow-up, although more than 50% of the patients were lost to follow-up. Implications of the present findings for behavioral and educational interventions are discussed.     

Sex roles and friendship patterns

The purpose of this study is to examine the relationships among sex, sex role orientation, and friendship. Based on the Bem Sex Role Inventory, 164 participants were categorized as either androgynous (17 males; 29 females), traditional (36 males; 39 females), or undifferentiated (26 males; 17 females) in their sex role orientation. Participants reported the number of close male and female friends, and responded to several questionnaires: interpersonal trust of male and female friends, communal and exchange orientations, affective and activity attributes associated with male and female friends, loneliness, and friendship satisfaction. Results indicate that close friends tended to be same sex, even though females had more close friends overall than did the males. Androgyny was related to characteristics that enhance the development and maintenance of close friendships, such as a communal orientation and positive conceptions of friends, while the undifferentiated orientation was related to less relationship enhancing orientations and a less rewarding interpersonal milieu. The study confirms that sex and sex role orientation are important factors in both quantitative and qualitative aspects of friendship during young adulthood.Portions of this paper were presented at the annual convention of the Southwestern Psychological Association, Houston, Texas, April 13, 1989. We appreciate the extensive help of an anonymous reviewer on earlier versions of this paper.     

Open-field behavior in domestic chicks tested individually or in pairs: Differential effects of painted lines delineating subdivisions of the floor

The open field is a common test of fear, but the apparatus varies widely. Lines painted on the floor facilitate measurement of locomotion (areas entered), but, though some animals balk at lines, this variable has received little attention. In Experiment 1, 10-day-old female chicks were tested individually in an open field with an unmarked floor or one delineated into areas by 1- or 3-mm-wide black lines. In Experiment 2, chicks were tested in pairs in the presence or absence of 3-mm-wide lines. Strong intraindividual correlations demonstrated that both paces and areas entered are effective measures of locomotion. Chicks tested individually were unaffected by the presence or width of lines. Conversely, pair-tested chicks paced and pecked more when the floor was delineated. Given the latter findings, some standardization is recommended.     

Preventing the Application of Stereotypic Biases in the Courtroom: The Role of Detailed Testimony1

To determine whether detailed testimony has equivalent effects on judgments of stereotyped and nonstereotyped defendants, subjects read a synopsis of a criminal court case in which the defendant either was a stereotyped offender or was not. Additionally, the degree of detail in the prosecution testimony and defense testimony was varied. Results indicated that defendant stereotypicality had a greater impact under conditions in which witnesses provided equal amounts of detail in their testimony. When witnesses differed in the degree of detail in their testimony, the stereotypicality of the defendant was disregarded and judgments favored the witness who provided greater detail. These findings suggest that stereotype application is not inevitable; rather, stereotypes may bias jurors' decision-making processes when the quality and quantity of the evidence does not easily lead to a confident judgment.     

Late Adolescents' Experiences With and Attitudes Toward Videogames1

A total of 229 late adolescents (a large majority 15 to 19 years of age) completed a questionnaire that assesses a broad range of videogame-relevant experiences, preferences, and attitudes. Videogame playing was found to be a more popular, and a more highly regarded, activity among males than females. Gender differences were also found in participants' ratings of their motivations for playing videogames, their evaluations of particular characteristics of videogames, and their selection of their “most favorite” videogame. The differences between frequent and infrequent videogame players appeared to be limited to differences in the extent to which videogame playing is pursued and evaluated as a positive leisure activity, rather than reflecting broad differences in interest or personality. Some relations were found between participants' self-reported personality characteristics (i.e., self-esteem, empathy, conscientiousness, and introversion) and their attitudes toward videogames.     

Perceived Overqualification, Emotional Support, and Health

In the present study, we examined the effects of perceived overqualification on health and the moderating effect of emotional support. Exploratory and confirmatory factor analyses found 2 indicators of perceived overqualification: "mismatch" and "no-grow." Perceived mismatch had a significant negative effect on health but perceived no-grow did not. The main effect revealed that the greater the perceived emotional support, the greater the health. The significant interaction of perceived emotional support and mismatch, and perceived emotional support and no-grow on health indicates that the negative effects of overqualification on health was greater for those perceiving low emotional support than for those perceiving high emotional support. The significance of social support in illuminating the relationship between perceived overqualification and health are discussed.     

Positive Psychological States in the Daily Life of a Sample of Working Women

This study of a sample of working women investigated where positive experiences were derived from in everyday life, focusing on the domains of work and nonwork (leisure). It examined how aspects of the situation, in terms of principal environmental influences in work and leisure, and the person, in terms of locus of control, were associated with positive subjective states and psychological well-being. The study employed questionnaires and also the experience sampling method. The results showed that both work and leisure were important for positive psychological states and that internal locus of control was associated with greater enjoyment, interest, feelings of immediate control, intrinsic motivation, life satisfaction, and affective well-being and a number of principal environmental influences.     

Personality and charismatic experience among adult christians

A sample of 368 committed Christian adults completed the Index of Charismatic Experience together with the short form Revised Eysenck Personality Questionnaire and the Myers Briggs Type Indicator (MBTI). The data demonstrate that, according to the MBTI typology, Christians who prefer “thinking” are likely to score higher on the Index of Charismatic Experience than Christians who prefer “feeling”. According to the Eysenckian dimensional model of personality, the charismatic experience is associated with stable extraversion.     

Unification,Reduction, and Non-Ideal Explanations

Kitcher's unification theory of explanation seems to suggest that only the most reductive accounts can legitimately be termed explanatory. This is not what we find in actual scientific practice. In this paper, I attempt to reconcile these ideas. I claim that Kitcher's theory picks out ideal explanations, but that our term explanation is used to cover other accounts that have a certain relationship with the ideal accounts. At times, versions and portions of ideal explanations can also be considered explanatory.
