Abstract

Happiness and positive moods influence health, and vice versa. A number of social and personality factors influence health directly, for example by affecting health behaviour or the immune system. These factors also affect health indirectly by influencing happiness and moods. These factors include social relationships, exercise and other aspects of leisure, job status and other aspects of work, social class, and several aspects of personality. The evidence on direct and indirect influences of happiness on health is summarised here.     

Resilient Children: Individual Differences in Developmental Outcome of Children Born to Drug Abusers

Since 1977, we have been following the neurobehavioral development of two groups of children: a group born to women on methadone maintenance and a drug-free comparison group. This study used the data on the children evaluated at 36 months of age to determine whether distinct patterns of developmental outcome can be identified, and which medical, familial, or environmental characteristics are associated with developmental differences. The children were clustered on four measures at 36 months: head circumference percentile, Merrill-Palmer Scale score, neurological evaluation, and referrals for developmental problems. Three distinct clusters emerged, with methadone children disproportionately frequent in Cluster 3, the group showing the poorest development. Comparisons of the clusters on a wide range of variables revealed consistent differences between Cluster 1 and Cluster 3 children in maternal responsiveness and incidence of neglect and family violence. These findings indicate that distinct developmental patterns do occur within this predominantly lower-class ghetto population; further, that children born to methadone-maintained women are more likely to show poor development. However, when the environment provides nurturance and stability, methadone children can show resilience and develop well.     

Activity under Low Motivational Levels as a Function of the Method of Manipulating the Deprivation Period

Boys and girls in Grades 4, 6, and 8 were presented a 48-word list, in which each item was associated with a 5¢, 3¢, or l¢ reward, in order to test incentive effects on storage by means of a forced choice recognition paradigm assumed to minimize retrieval effects. Results showed (a) higher probabilities of recognition for words associated with higher incentive values, (b) serial position effects, and (c) a suggestive developmental progression in recognition performance. Differential reward influences upon storage and serial position were interpreted in terms of two-process memorial and incentive theories.     

The Assessment of Post‐traumatic Stress Disorder for Workers' Compensation in Emergency Service Personnel

There is considerable debate concerning the diagnosis of post‐traumatic stress disorder (PTSD) in compensation claims. This study reviewed the quality of the assessment reports prepared by clinicians who evaluated 31 emergency service workers making PTSD‐related compensation claims. Assessments were conducted by 4‐year trained psychologists (39%), psychologists holding a masters degree (36%), and psychiatrists (19%). The assessment reports were evaluated relative to the diagnostic criteria for PTSD in the Diagnostic and Statistical Manual of Mental Disorders 4th edition (2000). In the majority of cases (81%), the assessor determined that the emergency service worker had PTSD, but only one report met the minimum standard for that diagnosis. In the majority (65%) of cases the clinician failed to address the possibility of malingering. These data suggest that clinical assessment reports for PTSD frequently fail to meet minimum assessment standards.     

Studies in the Principles of Judgments and Attitudes: I. Two Basic Principles of Judgment

The psychological test performance of 10 seven-year-old boys from an isolated, rural Guatemalan village was compared with ratings of their intelligence made by 42 adult village members. The adults' judgments were found to correlate strongly with the children's performance on the Embedded Figures, Verbal Analogies, and Memory-for-Designs Tests.     

Manipulation of visual information does not change the accuracy of distance estimation during a blindfolded walking task

While humans rely on vision during navigation, they are also competent at navigating non-visually. However, non-visual navigation over large distances is not very accurate and can accumulate error. Currently, it is unclear whether this accumulation of error is due to the visual estimate of the distance or to the locomotor production of the distance. In a series of experiments, using a blindfolded walking test, we examine whether enhancing the visual estimate of the distance to a previously seen target, through environmental enrichment, visual imagery, or repeated exposure would improve the accuracy of blindfold navigation across different distances. We also attempt to decrease the visual estimate in order to see if the opposite effect would occur. Our results would indicate that manipulation of the static visual distance estimate did not change the navigation accuracy to any great extent. The only condition that improved accuracy was repeated exposure to the environment through practice. These results suggest that error observed during blindfold navigation may be due to the locomotor production of the distance, rather than the visual process.     

Preparation for marriage: Beyond the classroom

Abstract

The frustrated sexual needs of the “aging” population have been largely neglected in the professional literature. This bespecially true of the female population, leading the individual post-menopausal woman to believe that she is abnormal in desiring and experiencing sex. The problem must be faced. That sex can be used for relational a d recreational purposes is a historically new concept, which must extend to the older woman as well. The post-menopausal client must be helped to see sexuality at her age as healthy both physically and psychologically.     

Talk about a past relationship partner: Metacommunicative implications

Abstract

Within many intimate dyadic relationships, individuals talk to their partners about a past relationship with a former spouse or lover. The impact that “talk about a past partner” (Tapp) has on one's current relationship is reviewed. Four metacommunicative functions of Tapp are suggested: disclosing past relationship history, conveying relationship rules or expectations, creating closeness or distance, and confirming self-perceptions. It is argued that the role of Tapp, within any given relationship, not only affects partners' feelings of security, control, closeness, etc., but also may reveal their characteristic patterns of communicating, metacomrnunicat-ing, interpreting and misinterpreting.     

“We Learn How to Predict and be a Scientist”: Early Science Experiences and Kindergarten Children's Social Meanings About Science

We examine kindergarten children's emerging social meanings about science as a function of their participation in integrated science inquiry and literacy activities associated with the Scientific Literacy Project (SLP). We describe changes in 123 SLP kindergarten children's narrative accounts of learning science in school during three different time periods: (a) in September, before the onset of SLP activities; (b) in December, after children had participated in 17 lessons associated with 4 SLP units; and (c) in March, after children had participated in an additional 13 lessons associated with the SLP Marine Life unit. At the end of the year, we: (a) compare SLP children's narratives about science to those of a group of children (n = 70) who only experienced the regular kindergarten program; and (b) examine differences between SLP and comparison children's reports on a measure of learning activities in kindergarten that include science as well as privileged content areas such as reading, writing, and learning about numbers and shapes. Results support the conclusion that sustained and meaningful participation in conceptually coherent science programs is crucial for children to develop meanings about science as a distinct academic domain that comprises its own disciplinary content, language, and processes.
