Choice with initial and terminal link reinforcement: an alternative self-control paradigm

Self-control is demonstrated when a less desirable immediate outcome is chosen to ensure a substantially better future. In a novel animal analogue of this situation, primary reinforcement was delivered in both the initial and terminal links of a concurrent chain schedule. Rats made initial link choices between equal amounts of ethanol-free or ethanol-containing milk. Choosing the ethanol-free reinforcer resulted in delivery of the larger terminal link reinforcer and was thus analogous to self-control. Self-control decreased as the delay between initial and terminal links increased. The results have implications for human choice situations where decisions are made between two immediately available reinforcement alternatives each associated with a different delayed outcome.     

Changes in behavior and behavioral intentions among middle-age women: results from an osteoporosis prevention program

The purpose of this study was to evaluate changes in behaviors and behavioral intentions that occurred among 342 middle-age women (M age 49.5 yr.) after participating in an Osteoporosis Prevention Program. The valid and reliable Osteoporosis Preventing Behaviors Survey (developed by Doheny and Sedlak) and a survey developed for this work were measures. Significant changes in behaviors were reported, especially increases in weight-bearing physical activity, dairy product intake, and decreases in consumption of caffeine-containing beverages. Many subjects reported intentions to increase physical activity and calcium intake. An Osteoporosis Prevention Program may help promote osteoporosis prevention behaviors, but intents must be followed up to check actual change.     

Dairy-product intake and hip fracture among older women: issues for health behavior

The purpose of this study was to examine the association between dairy-product intake and hip fracture among a national sample of women aged 50 years and older. Univariate analyses using SAS procedures showed dairy-product intake was significantly associated with hip fracture. Women who had suffered hip fracture reported higher dairy use than women who had not experienced these fractures, a finding that is dramatically inconsistent with the literature. This finding may reflect positive behavioral changes resulting from the hip fracture event. Further research must focus on changes in health behavior after fracture, which may assist in understanding the roles of specific theories of health behavior. Application of principles of health behavior could improve the effectiveness of preventive treatment programs for osteoporosis.     

Managing the demonic: Some aspects of the neo‐Pentecostal deliverance ministry

Few people would doubt that alternative therapies have become increasingly popular over the last two decades in Western societies. The expulsion of evil spirits, otherwise known as ‘deliverance’, in order to overcome physical, psychological and emotional problems might appear to be on the fringe of the most ‘fringe’ alternatives. Nevertheless, in Christian charismatic circles the practice is of central importance over and above the apparent aim of spiritual healing. This article explains what deliverance involves with reference to observations and interviews conducted during field work study at deliverance meetings and training sessions. I conclude by exploring a number of sociological themes which might allow an insight into its wider frinctions. In doing so I will contend that deliverance provides a purpose for the charismatic community in upholding boundary maintenance, as well as integrating and sustaining the individual within the collective.     

Relationship between birth order and leadership style for nursery school children

36 nursery school children were given a revised form of Fiedler's (1967) least preferred co-worker scale designated as the least preferred playmate scale. The purpose was to investigate the relationship between least preferred playmate scores and the birth order of young children. A 2 X 2 contingency table was constructed between birth order (first and later born) and leadership style (high and low). The resulting chi squares were insignificant for the total population and for males. However, for females the results were significant with a higher percentage of firstborns being task-oriented (low score) and a higher percentage of later borns being relation-oriented (high score).     

Completion of binary statements by children at three academic levels

This study was designed to examine the strategy employed by school-aged subjects when completing binary statements. Thirty-two incomplete binary statements representing four statement conditions (true affirmative, true negative, false affirmative, and false negative) were administered to 120 children randomly selected from three academic levels. A response-index change model is postulated as representing the strategy employed by these school-aged subjects when completing binary statements. According to this model, the factor that causes response time to differ across the four statement conditions is the number of times the child is required to change the set of his response index. The child begins the task of completing a binary statement by reading and encoding the incomplete statement. He then selects the numeral that corresponds to the adjective “odd” or “even” contained in the predicate of the incomplete statement. The child’s response index is now set to respond with this numeral. What the child does at this point will depend upon the type of statement condition with which he is working. If the child is completing a TA statement, no response-index change is required. He simply gives as his answer the numeral to which his response index is set. If the child is completing an FA statement or a TN statement, one response-index change is required. If the child is completing an FN statement, two response-index changes are required.     

COMPARING THE TORTOISE AND THE HARE:

Abstract— Recent research suggests that dynamic spatial reasoning tasks show more robust gender differences than static spatial reasoning tasks. These differences have implications for selection procedures based on aptitude test scores. Two experiments were therefore designed to examine the locus of such gender differences. In Experiment 1, 82 males and 82 females performed two separate tasks: judging the relative velocity of moving objects and judging their relative distances from target destinations. Significant gender differences occurred only for relative velocity judgments and were partially related to prior experience. A second experiment therefore tested the effects of practice and feedback on performance judging relative velocity. Male and female performance differences were again found, and performance improved equally as a result of feedback. Consistent with contemporary views of aptitude and assessment, the data suggest that equitable assessment of dynamic spatial abilities requires a determination of experiential history and learning rates as well as absolute performance levels.     

Expressiveness does predict well-being

Previous studies of sex role and well-being have yielded mixed results on the relationship between expressive traits and well-being. This may be due to methodological inconsistencies, problems inherent in early sex role inventories, and narrow definitions of well-being. This study assessed the relationship between the instrumental and expressive traits on the Short Bem Sex Role Inventory (SBSRI) and a composite picture of well-being, including depression, positive affect, affect balance, life satisfaction, and affect intensity, in a sample of primarily white middle-class college students. The two scales of the SBSRI predicted most aspects of well-being equally well, yielding two independent main effects. The expressive scale was the only significant predictor of affect intensity. Expressiveness scores were positively correlated with affect intensity overall, and with positive affect intensity in particular. It is suggested that the SBSRI is tapping two factors of a general positive self-schema, rather than sex role per se.Funds for this study were provided by the University of Pennsylvania Psychology Department.

An emergency situation simulator for examining time-pressured decision making

Between deliberate planning efforts and reactionary decision making lies a realm of time-pressured decision making. A number of real-world occupations deal with this realm on a regular basis, including air traffic controllers and emergency service dispatchers. To study this type of decision making, an emergency situation simulator has been developed, which recreates the stressful environment of the emergency service dispatcher by generating realistic hypothetical emergency situations.
