about the authors

After tobacco and alcohol, marijuana is the most frequently used and abused substance. Its use is particularly prevalent among young adults, aged 18 to 25. This study examines the role strain plays in chronic (as opposed to recreational) marijuana use. Three theoretical perspectives are included in this analysis: General Strain Theory, Social Learning, and Self Control. Data from the 2001 National Household Survey of Drug Abuse are used to determine the relative effects of peers (social learning), strain (general strain theory), and favorable attitudes toward risk-taking (self control). Data is divided into subsamples on the basis of gender. Logistic Regression analysis suggests that males are more likely to be chronic users, and that psychological strain, social learning, and low self control are significant factors associated with chronic use. Furthermore, strain has a stronger effect on chronic use for minority group members, as does a propensity to risky behavior. Social learning has a stronger effect on nonminority group members. All factors have a stronger significant effect on female chronic marijuana use than on male marijuana use (except for the demographic variable education). Policy implications and suggestions for future research are also included.     

Are You Kynd? Conformity and Deviance Within the Jamband Subculture

I use measures of interpersonal involvement specific to differential association theory to explain variation within the jamband subculture. Specifically, I examine the relationship between the differential association modalities (frequency, intensity, priority, and duration) and the affective meanings (evaluation, potency, and activity) associated with six behaviors that are relevant to that subculture. I expect the modalities to be related positively to the evaluation and potency of four prosocial (what I term “kynd”) behaviors (to barter, to follow a band, to share, to trade music) and negatively to the evaluation and potency of two “unkynd” behaviors (to talk down, to threaten). Using data from self-administered surveys (n = 379), I find that frequency and intensity predict variation in the affective meaning of kynd and unkynd behaviors. However, priority and duration generally do not predict variation in the affective meaning of kynd and unkynd behaviors.     

Teaching Ethical Decision Making: Designing a Personal Value Portrait to Ignite Creativity and Promote Personal Engagement in Case Method Analysis

The case method approach to introducing ethical issues is a traditional tool for applying critical thinking skills to a specific dilemma (Beauchamp &; Childress, 2001 Beauchamp, T. L. and Childress, J. F. 2001. Principles of biomedical ethics, 5th, New York: Oxford University Press.  [Google Scholar]). It allows for personal reflection and clarification of an individual's conceptual framework for deciding what is and is not ethical behavior. However, it also affords the student distance from the story line and may, through providing a retrospective critique, prevent sufficient challenge to the student to articulate and defend personal value assessments in addressing the ethical dynamics reflected in the case. Providing teaching exercises that encourage the creation of language to form that conceptual framework and a comfort in using that language allows the student to not only identify ethical issues but also recognize and more effectively communicate the struggles with molding a personal values portrait to apply to such cases.     

Influence of African American elders’ age stereotypes on their cardiovascular response to stress

Abstract

Although it has been shown that White elders are vulnerable to the influence of age stereotypes, it was not known whether this effect applied to African American elders. In the present study, African American elders were randomly assigned to negative or positive implicit-age-stereotype groups. Compared to participants in the positive age-stereotype group, those in the negative age-stereotype group demonstrated significantly more elevated cardiovascular response to stress, as measured by blood pressure and heart rate following mental challenges. These results suggest that negative age stereotypes generate a susceptibility to stress among African American elders, whereas positive age may provide them with a defense against this stress.     

Looking at others through implicitly or explicitly prejudiced eyes

It is well known that we utilize internalized representations (or schemas) to direct our eyes when exploring visual stimuli. Interestingly, our schemas for human faces are known to reflect systematic differences that are consistent with one's level of racial prejudice. However, whether one's level or type of racial prejudice can differentially regulate how we visually explore faces that are the target of prejudice is currently unknown. Here, White participants varying in their level of implicit or explicit prejudice viewed Black faces and White faces (with the latter serving as a control) while having their gaze behaviour recorded with an eye-tracker. The results show that, regardless of prejudice type (i.e., implicit or explicit), participants high in racial prejudice examine faces differently than those low in racial prejudice. Specifically, individuals high in explicit racial prejudice were more likely to fixate on the mouth region of Black faces when compared to individuals low in explicit prejudice, and exhibited less consistency in their scanning of faces irrespective of race. On the other hand, individuals high in implicit racial prejudice tended to focus on the region between the eyes, regardless of face race. It therefore seems that racial prejudice guides target-race specific patterns of looking behaviour, and may also contribute to general patterns of looking behaviour when visually exploring human faces.     

Word List Generation Performancein Alzheimer's Disease and Vascular Dementia

Word list generation (WLG) was examined among clinical samples of individuals with Alzheimer's disease (AD) (n = 73) or ischemic vascular dementia (IVD) (n = 85), equivalent in age, education, current and estimated premorbid intellectual functioning, and proportion of men and women. The AD group performed significantly better than did the IVD group on lexical WLG, and a trend was observed indicating superior performance among the IVD group on categorical WLG. Within-groups, comparisons of group means, and profile analyses of individual performance patterns all indicated that persons with AD demonstrated a lexical > categorical pattern significantly more often than did IVD participants. The absolute difference in average performance between the AD and IVD groups on lexical and categorical WLG was small; the findings, however, generally support the clinical utility of the lexical > categorical WLG pattern in the differential diagnosis of AD and IVD. The patterns of performance support the presence of relative impairment in semantic processing among the individuals with AD and global deficits in retrieval and processing speed in individuals with IVD.     

Test–Retest Reliability of the ECO Computerised Cognitive Battery for the Elderly

The current study presents the test–retest reliability data for the ECO (Examen Cognitif par Ordinateur) computerised cognitive battery developed by Ritchie et al. (1993). Repeat testings were conducted using a sample of 36 healthy elderly with normal cognitive functioning. Sixteen of the battery’s 23 subtests yielded significant correlation coefficients ranging from .42 to .90 (Pearson’s r). A mild practice effect was detected with two of the seven memory tests and two of the seven visuospatial tests (p <.05). Comments about the sources of measurement error and recommendations for further test development are made.     

Job stress and attitudes toward change: The mediating effect of psychological attachment

The present study explores the indirect effect of job stress on attitudes toward change through individuals’ psychological attachment (organisational commitment mindsets and job embeddedness). The sample comprised N = 350 employees (black African: 67%; males: 69%; 26–40 years: 67%) who were affected by organisational change in the South African fast-moving consumer goods sector. The participants completed self-report measures on their job stress and psychological attachment experiences and their attitudes towards organisational change. The analysis applied structural equation modelling to test for the mediation effect of psychological attachment on the link between job stress and attitudes toward change. The findings suggest job stress to have a direct negative effect on job embeddedness and a positive, direct effect on attitudes toward change. Low levels of job embeddedness had a direct effect on positive attitudes toward change and mediated the link between job stress and attitudes toward change. The study contributes to organisational change theory by suggesting that experiences of job stress lower employees’ job embeddedness and this lowered sense of attachment translates into change-supportive attitudes.     

Knowledge,Beliefs and Attitudes Regarding Abortion in South Africa Among a Sample of University Students

A survey study design was used to determine the knowledge of a sample of South African university students regarding the Choice on Termination of Pregnancy (CTOP) Act and their beliefs and attitudes toward abortion. A total of 146 (110 female, 36 male) undergraduate psychology students participated in the study. As part of a larger study participants were given a questionnaire on knowledge, beliefs, attitudes and practices regarding sexuality among young South Africans. The results showed that most of the students were unaware of key provisions of the Act. The data also indicated opposition to abortion except in the case of rape or when the pregnancy posed a threat to the health of the woman. It is concluded that increasing public awareness of the Act is vital not only in improving access to abortion services but also in terms of reducing the stigma that seems to be associated with abortion in South Africa.     

Subdimensional Structure of the Hogan Personality Inventory

This study examined the subdimensional structure of the Hogan Personality Inventory (HPI). A sample of 200 Spanish applicants completed the HPI as a requirement of a selection process for several jobs at a large international company. Exploratory factor analyses were conducted with the homogenous item composites (HIC) included in the HPI. Globally, the results indicated that the Big Five are divided into 13 subdimensions, which explained the variance of the HICs. Based on these results, we suggest that the HPI can be described as a personality inventory consisting of a hierarchical structure of three levels (Big Five – subdimensions – HICs).
