Dynamic spatial performance and general intelligence

A computerized video-game-like dynamic spatial ability measure and a paper-and-pencil group test of intelligence were administered to 94 university students. The purpose of the study was threefold: (a) to evaluate the reliability of the dynamic spatial measure; (b) to investigate the extent to which the dynamic spatial measure is saturated with variance associated with traditional measures of fluid and crystallized intellectual ability; and (c) to explore the possibility that dynamic computer based performance measures define factors that are distinct from those associated with traditional paper-and-pencil measures. The number of times the participant hit a moving target served as the dependent variable for the dynamic spatial measure. Number of hits proved to be correlated with Performance IQ, but was not significantly correlated with Verbal IQ. Maximum likelihood factor analysis revealed that the dynamic spatial measure did not load substantially on a factor of general intellectual ability but provided additional evidence that it is related to a performance component.     

Psychological androgyny: A black female perspective

The focus of the present study is the relationship between Masculine and Feminine personality attributes (as measured by the PAQ), sex role attitudes, and socialization antecedents among a sample of Black women. The majority of the Black women in this study report Androgynous sexual identities, but have traditional beliefs about the female role in the family. Androgynous women are more likely to be positively identified with both mother and father. Women who are college graduates have more liberal views about the female role and are more likely to identify themselves as Masculine and Undifferentiated. Regardless of sexual identity category, the subjects are all heavily invested in the mothering role. Racial comparisons indicate more Black women are in the Androgynous category and more White women in the Undifferentiated category. White respondents have more liberal sex role attitudes than the Black respondents.     

Informal Caregiving to Persons with AIDS in the United States: Caregiver Burden Among Central Cities Residents Eighteen to Forty-Nine Years Old

Characteristics and caregiving experiences of friends and family members caring for people with AIDS (PWAs) were examined. Based on a probability sample of informal AIDS caregivers ages 18–49 living in central cities of the United States (n = 260), analyses were conducted to (a) identify the sociodemographic characteristics of young central city caregivers; and (b) examine the effects of caregiver characteristics (relationship to PWA, gender, race/ethnicity, income, sexual orientation, HIV status, perceived susceptibility), and level of objective caregiving demands, on subjective caregiver burden. Results indicate that the largest group of caregivers in this age category are male friends of the PWA—a group not typically found among caregivers to persons with other types of illnesses. In general, gay or bisexual caregivers, caregivers who have traditional family ties to the PWA, men relative to women, and lower income caregivers, report the greatest burden. While level of caregiving demands represents the most influential predictor of caregiver burden, white and male caregivers experience greater burden, independent of level of involvement and other caregiver characteristics. Receiving instrumental support with caregiving buffers the impact of high objective demands on subjective burden.     

Gender, object, and humor

Male and female respondents rated jokes with either a female initiator/male target of joke or vice versa. For male respondents, the gender of the joke target made no difference. For female respondents, however, jokes with males as the target received significantly higher ratings than jokes with females as the target.     

Hippocampal synaptic plasticity during instrumental learning

present research examined the role of hippocampal NMDA-dependent synaptic potentiation on appetitive instrumental conditioning under a continuous reinforcement schedule. In the first experiment, low (.025 mg.kg) or moderate (.05 mg/kg) dosages of the NMDA receptor antagonist, MK801, failed to increase the number of training days required to reach acquisition criterion; number of training days required to reach criterion for extinction were also unaffected. In the second experiment, a higher dosage (.10 mg/kg) of MK801 or induction of long-term potentiation failed to alter the number of responses occurring during acquisition. These data suggest that hippocampal synaptic potentiation does not play a prominent role in instrumental learning with simple contingency conditions. It is suggested that hippocampal LTP reflects a perceptual process that contributes differentially to spatial cognition, classical and instrumental conditioning.     

Developing local lifelong guidance strategies

The background, rationale, methodology and outcomes of a project on developing local lifelong guidance strategies in four areas are outlined. The main components of the strategies developed in the four areas are analysed, and a number of issues relating to the process of strategy development are addressed. Much of the lack of coherence at local level stems from lack of coherence at national policy level: implications for national policy are examined. Finally, implications for parallel work in other localities are explored.

Textbooks in Accredited Marriage and Family Therapy Programs

Although choices of required textbooks are important decisions in developing a course curriculum, faculty in marriage and family therapy training programs have few convenient resources to guide curriculum development. This article presents results of a survey of textbook selections of accredited marriage and family therapy programs within a regional affiliate of AAMFT. The five programs surveyed listed 108 different titles used in their curriculum. Only 12 texts were used by two programs, and only one text was used by more than two programs. This article presents the textbook selections by the six curricular areas of COAMFTE accreditation standards. The wide variety of textbooks used by programs leads us to conclude that no consensus exists about what textbooks best represent the core knowledge of marriage and family therapy. The body of knowledge taught in accredited marriage and family training programs reflects a distinct and autonomous body of knowledge.     

WORKING MEMORY CAPACITY DISSOCIATES LEXICAL AND SENTENTIAL CONTEXT EFFECTS

Abstract— Semantically associated and unassociated word pairs were embedded in normal meaningful sentences and in sentences that were semantically anomalous throughout The influence of lexical context was isolated via comparison of responses to the second words of the associated and unassociated pairs. The influence of sentence-level context was isolated by comparing responses to the same words in the two sentence types Subjects of high, medium and low working memory capacity (as evaluated by the reading span test) showed modulations of event-related brain potentials in response so lexical context. In contrast, only the high- and medium-capacity groups were responsive to purely sentence-level semantic context. The results demonstrate that sentential context influences the processing of words in intermediate sentence positions at normal reading speeds but that the on-line utilization of this context is more demanding of working memory than single-word contexts.     

Socialization influences of collegiate female athletes: A tale of two decades

Over the past decade, sport participation opportunities for females have increased dramatically. The purposes of this study were to compare perceptions of encouragement and support from socializing agents for: (a) female collegiate volleyball players competing during the 1979 and 1989 seasons, and (b) female collegiate athletes and female and male nonathletes. Female athletes (n= 345), female nonathletes (n= 128), and male nonathletes (n= 88) completed a questionnaire to assess significant others' influence on sport involvement during childhood, adolescence, and college years. Results indicated that interest and encouragement by parents, older siblings, and friends significantly increased for female athletes over the past 10 years during one or more developmental period. Discriminant analyses revealed that female athletes perceived stronger influences from mother, siblings, friends, and coaches than did male and female nonathletes. These results demonstrate that female athletes received greater social support than their peers a decade earlier, and these influences were significantly different than male and female nonathletes. This study was supported by a grant awarded to the first author by the Center for the Study of Women in Society, University of Oregon, Eugene.
