The effect of humorous instructional materials on interest in a math task

Two studies tested the effect of humor, embedded in learning materials, on task interest. College student participants (N _{Study 1} = 359, N _{Study 2} = 172) learned a new math technique with the presence or absence of humor in the learning program and/or test instructions. Individual interest in math was measured initially and also tested as a factor. The results showed that the effect of humor in the learning program depended on individual interest in math. Humor raised task interest for those with low individual interest in math but slightly lowered task interest for those with high individual interest in math. Mediating variables of this effect were tested across both studies. Although the mediating variables showed inconsistency, humor may affect task interest through affective responses immediately following the instruction, rather than in subsequent interaction with the task.     

Grandmothers as Gems of Genetic Wisdom: Exploring South African Traditional Beliefs About the Causes of Childhood Genetic Disorders

With its diverse cultural and linguistic profile, South Africa provides a unique context to explore contextual influences on the process of genetic counseling. Prior research suggests intergenerational differences regarding models of causation which influence treatment-seeking paths. This pilot study therefore aimed to explore South African traditional beliefs regarding common childhood genetic disorders. Three focus groups were conducted with fifteen grandmothers from different cultural backgrounds in an urban community. Questions pertained to the role of the grandmother, traditional beliefs regarding causes of genetic disorders, explanations of heredity, and prevention and management of genetic disorders. Results indicate a variety of cultural explanations for causes of childhood genetic disorders. These causes can be classified into categories related to lifestyle, behavior, social issues, culture, religion, genetic, and familial causes. Prevention and treatment issues are also highlighted. These findings have implications for genetic counseling practice, which needs to include a greater focus on cultural issues.     

A multimethod investigation of the behavioral activation system in bipolar disorder

Dysregulation in behavioral activation system (BAS) activity has been implicated in the pathogenesis of bipolar disorder (BPD). To characterize BAS activity and related facets in this disorder, the authors compared 59 participants with BPD to 44 controls on multiple measures of BAS activity, including a standardized behavioral task, self-reports, and electroencephalographic indexes of regional cortical activity. Levels of putative BAS activity differed depending on assessment strategy. When a behavioral task indexing reward sensitivity was used, euthymic BPD patients showed evidence of higher BAS activity than either control participants or patients who were in a mood episode. Following a mood induction procedure designed to elicit BAS activity, currently episodic patients showed relatively greater left anterior cortical activity than either euthymic or control participants. Implications of the findings for future research on BPD vulnerability are described.     

Awareness of Death Among Children: Does a Life-Threatening Illness Alter the Process of Discovery?

The authors review studies on death awareness among children who are healthy, chronically ill, and terminally ill. The review suggests that children with life-threatening diseases demonstrate increased understanding of death compared with children who are either healthy or chronically ill. In particular, children with terminal illness, especially during the end stage of their disease, show an advanced understanding of the death concepts of irreversibility and finality. In contrast, healthy and chronically ill children appear to require certain age, cognitive developmental level, or intelligence thresholds to understand these concepts. Possible explanations for the findings in this literature are discussed. The implications of death awareness research for counselors are used as a base for suggesting counseling strategies.     

A PSYCHOLOGICAL NEEDS ANALYSIS OF MALE AND FEMALE SEX TRAIT STEREOTYPES IN MALAYSIA

As part of a cross-cultural project, 100 Malaysian university students completed Gough and Heilbrun's (1965) Adjective Check List to assess existing stereotypes of males and females. After the construction of 100 item stereotypes for males and females the data were analyzed in terms of Murray's (1938) personality theory of psychological needs. Analysis revealed that the male “personality” reflected high needs in autonomy, aggression and exhibition, but low needs for deference and nurturance. By contrast, female needs were strong in succorance and abasement but weak in dominance. These results were contrasted with those of 21 other countries and findings discussed in terms of Malaysia's multi-racial composition and influence of traditional customs and religious beliefs.     

Case study: Use of propranolol to reduce aggressive behavior in a woman who is mentally retarded

Although neuroleptic medications are frequently used to treat the aggressive behavior of persons with mental retardation, little empirical support exists for their efficacy. In the case study reported here, the beta-blocker propranolol was used to treat the aggressive behavior of a 23-year-old woman with severe mental retardation. Initiation of treatment was correlated with a dramatic decrease in aggression and a less pronounced improvement in self-injurious behavior (SIB). An increase in resting heart-rate was associated with a significant increase in aggression, and progressive increases in propranolol dosage were correlated with reductions in heart rate and in significant behavioral improvement. Consideration of propranolol as a less intrusive, and possibly more effective, pharmacologic treatment for the aggressive behavior of persons with mental retardation is discussed.     

Psychological and Socio-cultural Adjustment during Cross-cultural Transitions: A Comparison of Secondary Students Overseas and at Home

The study further explores the distinction of psychological and socio-cultural adjustment during cross-cultural transitions. One hundred and seventy-eight New Zealand American Field Service (AFS) students residing in 23 different countries completed questionnaires which contained assessments of the following: Personality (extraversion and locus of control); life changes (Social Readjustment Rating Questionnaire); homesickness, cultural distance, acculturation (cultural identity and cultural integration—separation); attitudes toward host country; language ability; amount of contact with host and co-nationals; relationship satisfaction with co-nationals, host nationals and host family; and outcome measures of socio-cultural (social difficulty) and psychological adjustment (Profile of Mood States). Stepwise regressions revealed that homesickness, external locus of control, life changes, and social difficulty accounted for 55% of the variance in psychological adjustment. In contrast, cultural distance, language ability, satisfaction with host national contact, cultural separation and mood disturbance explained 52% of the variance in socio-cultural adaptation. In the second part of the research, psychological and socio-cultural adjustment of AFS students was compared with a sample of 142 home-based New Zealand secondary school students. Although there were no significant differences in psychological adjustment between the two groups, the students who were resident abroad experienced greater socio-cultural difficulties than the students resident in New Zealand (P < 0.0005), and, as hypothesized, the correlation between psychological and socio-cultural adjustment was significantly greater in the home-based students compared to the AFS group (P < 0.0001).     

Novel odors evoke risk assessment and suppress appetitive behaviors in mice

The effects of four novel odors on risk assessment by mice (i. e., flat back approach, stretched attention, immobility) and the suppression of appetitive behaviors were examined in two experiments. When novel odors were presented in a straight runway, subjects spent significantly less time in the odor compartment, relative to controls, when it contained sheep wool, chocolate, or citronella (but not cat fur) odors. Risk assessment behaviors occurred at similar levels among all groups and appetitive behaviors were not suppressed by the novel odors. When odorants were scattered over one half of the subjects' home cage floor in Experiment 2, all novel odors increased the duration of at least on e risk assessment measure and/or suppressed appetitive behaviors (i. e., eating, grooming, rearing). The results clearly reveal that a reasonably wide range of novel odors evoke at least some level of risk assessment which presumably reflects increased fearfulness. The odors of sheep wool and cat fur induced a wider range of such responses than did chocolate or cinnamon suggesting that mammalian odors may be particularly effective stimuli. If so, however, it is clear that predator odors are not uniquely effective in this regard. Experiment 1 also underscores the importance of the testing environment in assessing the behavioral effects of novel odors in mice. © 1993 Wiley-Liss, Inc.
