A Dissociation between Symbolic Number Knowledge and Analogue Magnitude Information

Semantic understanding of numbers and related concepts can be dissociated from rote knowledge of arithmetic facts. However, distinctions among different kinds of semantic representations related to numbers have not been fully explored. Working with numbers and arithmetic requires representing semantic information that is both analogue (e.g., the approximate magnitude of a number) and symbolic (e.g., what / means). In this article, the authors describe a patient (MC) who exhibits a dissociation between tasks that require symbolic number knowledge (e.g., knowledge of arithmetic symbols including numbers, knowledge of concepts related to numbers such as rounding) and tasks that require an analogue magnitude representation (e.g., comparing size or frequency). MC is impaired on a variety of tasks that require symbolic number knowledge, but her ability to represent and process analogue magnitude information is intact. Her deficit in symbolic number knowledge extends to a variety of concepts related to numbers (e.g., decimal points, Roman numerals, what a quartet is) but not to any other semantic categories that we have tested. These findings suggest that symbolic number knowledge is a functionally independent component of the number processing system, that it is category specific, and that it is anatomically and functionally distinct from magnitude representations.     

Cultural Mistrust,Ethnic Identity,Racial Identity,and Self‐Esteem Among Ethnically Diverse Black University Students

Cultural mistrust, ethnic identity, racial identity, and self‐esteem were examined among African (n = 26), African American (n = 110), and West Indian/Caribbean (n = 24) university students. African American students' scores were statistically different from those of African and West Indian/Caribbean students on cultural mistrust, racial identity, and ethnic identity measures. There were no statistically significant differences on self‐esteem among the 3 groups. Results did indicate that cultural mistrust, ethnic identity, and racial identity accounted for 37% of the variance in self‐esteem for African American students. Implications for practice and future research directions are discussed.     

Religious Occupations and Stress Questionnaire (ROS): Instrument Development

The authors describe the development of the Religious Occupations and Stress Questionnaire (ROS), which attempts to fill the need for an appropriate measure of the stress experienced by individuals in religious occupations. The ROS has 4 stress‐related subscales (General Stress. Occupational Stress, Identity/Image Stress, and Gender Issues Stress) and a Coping subscale. Results of reliability and validity studies of the ROS with male and female Protestants, Catholics, and Jews who were in religious occupations indicated high internal consistency, test‐retest reliability, and construct validity.     

Stress and Immunity: Age Enhances the Risks

A competent immune response is central to good health. There is good evidence that both aging and psychological stress can dysregulate immune function, resulting in changes in various aspects of the immune response that are large enough to have consequences for health. Older adults appear to show even greater immunological impairments associated with stress or depression than younger adults. Thus, the data suggest that aging interacts with stress and depression to enhance risks for morbidity and mortality among older adults.     

EMPOWERING TOKEN WOMEN LEADERS

We hypothesized that, in a masculine task, only token women leaders who were empowered through position (by being appointed leader) and expertise (trained with task-relevant information) and legitimated by a male experimenter as credible would be more effective in influencing the performance of their all-male groups than appointed-only and appointed-trained leaders. Thirty women undergraduates each led a small group of male students on a moon survival task. The hypothesis was supported. Videotapes of group interactions revealed that appointed-trained leaders interrupted group members and used tentative tag questions in failed attempts to share their task-relevant knowledge. In addition, group members reported the most dissatisfaction with appointed-trained leaders who, without legitimacy, violated diffused gender roles by presuming to be expert on a masculine task. The importance of the organizational empowerment of token women is underscored.     

Self-esteem of female athletes and nonathletes relative to sex role type and sport type

The purpose of the present research was to investigate the relationship of the self-esteem of female athletes and nonathletes to sex role type and sport type. The athletic group was comprised of 75 female collegiate athletes from eight sports and the nonathletic group consisted of a random sample of 75 female nonathletes. An assessment of self-esteem and sex role type was completed through administering to all subjects the short form of the (PRF) ANDRO Scale of Masculinity and Femininity, and the Interpersonal Disposition Inventory (IDI). On the basis of the results of the IDI, the subjects were categorized into four sex role types: androgynous, masculine, feminine, and undifferentiated. Based upon previous research, it was predicted that (1) athletes would exhibit higher self-esteem scores than nonathletes, (2) the self-esteem of androgynous individuals would be higher than other sex role types, (3) the self-esteem of feminine or undifferentiated individuals would be lower than other sex role types, (4) the self-esteem of female athletes in higher femininity status sports would be greater than those in lower femininity status sports, and (5) there would be a greater proportion of androgynous athletes and feminine nonathletes. The following significant results were found: nonathletes in the feminine sex role type were lower in self-esteem than all other groups; and there was a greater proportion of androgynous athletes and feminine nonathletes than expected by chance. There were no differences in self-esteem of athletes in higher femininity status vs lower femininity status sports. These findings were discussed relative to past research, and the potential impact of sport on the psychosocial development or selection of certain sex role types.     

The role of spatial complexity in the perception of speech and pure tones in dichotic listening

Ear advantages for CV syllables were determined for 28 right-handed individuals in a target monitoring dichotic task. In addition, ear dominance for dichotically presented tones was determined when the frequency difference of the two tones was small compared to the center frequency and when the frequency difference of the tones was larger. On all three tasks, subjects provided subjective separability ratings as measures of the spatial complexity of the dichotic stimuli. The results indicated a robust right ear advantage (REA) for the CV syllables and a left ear dominance on the two tone tasks, with a significant shift toward right ear dominance when the frequency difference of the tones was large. Although separability ratings for the group data indicated an increase in the perceived spatial separation of the components of the tone complex across the two tone tasks, the separability judgment ratings and the ear dominance scores were not correlated for either tone task. A significant correlation, however, was evidenced between the laterality measure for speech and the judgment of separability, indicating that a REA of increased magnitude is associated with more clearly localized and spatially separate speech sounds. Finally, the dominance scores on the two tone tasks were uncorrelated with the laterality measures of the speech task, whereas the scores on the tone tasks were highly correlated. The results suggest that spatial complexity does play a role in the emergence of the REA for speech. However, the failure to find a relationship between speech and nonspeech tasks suggest that all perceptual asymmetries observed with dichotic stimuli cannot be accounted for by a single theoretical explanation.     

A comparative study of the impact of education vs. process groups for families of patients with affective disorders

This clinical project compares the relative impact of two types of multiple family groups on psychiatric inpatients and their families. Forty patients with a diagnosis of affective disorder, and their family members, were randomly assigned to a traditional multiple family group with a process orientation that emphasized support, destigmatization, and self-help about common problems; or to a psychoeducational multiple family group that emphasized the provision of information about the patient's illness and methods of coping with it effectively. Both groups, which met for four hours on a Saturday afternoon, were an integral part of an ongoing inpatient program specializing in the treatment of affective disorders. Pre- and post-measures were obtained regarding family and patient knowledge about affective disorders, level of personal distress, attitudes about the illness, and dyadic adjustment. In addition, both patients and family members were asked to rate their satisfaction with the group experience. A number of differences in knowledge, attitude and dyadic adjustment were found in the participants of both groups immediately following their respective group sessions, but there were only a few statistically significant differences between the two groups. Those who attended the psychoeducational session, however, reported significantly more satisfaction with the experience.
