DISCOUNTING OF DELAYED REWARDS:

Abstract— In this study, children, young adults, and older adults chose between immediate and delayed hypothetical monetary rewards The amount of the delayed reward was held constant while its delay was varied All three age groups showed delay discounting, that is, the amount of an immediate reward judged to be of equal value to the delayed reward decreased as a function of delay The rate of discounting was highest for children and lowest for older adults, predicting a life-span developmental trend toward increased selfcontrol Discounting of delayed rewards by all three age groups was well described by a single function with agesensitive parameters (all R²s>94) Thus, even though there are quantitative age differences in delay discounting, the existence of an age-invanant form of discount function suggests that the process of choosing between rewards of different amounts and delays is qualitatively similar across the life span     

Quality of relationships and structural properties of social support networks of female survivors of abuse

The purposes of this study were to examine the structural properties of the social support networks of female survivors of violence and abuse and to investigate the quality of the relationship, and specific level of satisfaction, survivors have with their social support networks. Participants averaged 5.8 persons in their social support networks. Their levels of satisfaction with the emotional, practical, financial, guidance, and socializing support they received from members of their social support networks were higher with respect to close friends and coworkers than with respect to family members and professionals (e.g., attorneys and social workers). The most common type of support provided by close friends who were themselves victims of abuse was emotional, guidance, and socializing support, and the most satisfying support was the financial and practical help that came from parents or family. An interesting finding was the significant presence of men in the survivors' social support networks. Overall satisfaction with the quality of support from the social support networks was high, and satisfaction with support from men was comparable, if not higher, than support from women. Multiple regression models revealed that satisfaction with support networks was a potent predictor of self-esteem, emotional health, and loneliness. Intimacy, especially in terms of exclusiveness and trust or loyalty, with at least a few members of the support network contributed significantly to the variance in self-esteem, emotional health, and loneliness among the abused women. The size of the support network also emerged as a limited contributor to well-being. Implications and applications are discussed for professionals working with female survivors of abuse.     

Application of Achievement Goal Theory in an Urban Youth Tennis Setting

The purpose of this study was to examine the motivational responses of tennis players in relation to their goal orientations and perceptions of the motivational climate. Youngsters completed a survey with tennis-specific measures of goal orientations, motivational climate, attitudes toward tennis, their instructor, their fellow players and sportspersonship behaviors. Results support Nicholls' goal perspective theory. Moderated regression analysis suggested that positive perceptions of a task-involving climate and negative perceptions of an ego-involving motivational climate predicted players' attitudes toward sportpersonship, their instructor, and fellow players. Attitudes toward tennis were predicted by task orientation. Canonical analyses further suggested that perceptions of the climate were most strongly related to attitudes.     

Exploring the Contribution of the Caring Climate to the Youth Sport Experience

The purpose of this study was to examine the relationship between young athletes’ perceptions of the caring climate on their soccer teams to their enjoyment, attitudes and, behaviors toward their coach and teammates, and commitment to the sport. Athletes (N = 184) in a community soccer league volunteered to complete a survey. Results revealed that athletes who perceived a caring climate on their teams were significantly more likely to report higher enjoyment, more positive attitudes towards their coaches/teammates, greater commitment to soccer, and engage in more caring behaviors towards their coaches/teammates. Results suggest that a caring climate may benefit young athletes.     

Paternal correlates of adolescents' running away behaviors: Implications for adolescent development and considerations for intervention and treatment of adolescent runaways

In recent years, research concerned with deviance in adolescent behaviors has become increasingly focused on the extent to which fathers influence their children's development. The present study, using an interdependent and mediational model of parent-child correlates, examined the interrelationships between father personality attributes and adolescents' running away behaviors. Two hundred adolescents (96 males; 104 females) from lower middle class homes and their fathers cooperated in the study. Findings showed that there are specific father attributes and socialization characteristics and adolescent personality attributes which interact significantly to influence adolescents' running away behaviors. Specific predictors of male and female adolescents' running away were examined and identified by means of discriminant function analyses. The results were interpreted within the framework of a mediational model. Implications of the findings were discussed for adolescent development and intervention programs for adolescents and their fathers.     

Left-handedness: association with college major, familial sinistrality, allergies, and asthma

366 juniors, seniors, and graduate students from seven departments at The Ohio State University were administered the 10-item Edinburgh Handedness Inventory and asked questions concerning familial handedness and personal incidence of allergies or asthma. The rate of left-handedness was 15.6% among the male students and 12.9% among the females. Maternal handedness was significantly related to female offspring handedness and to the incidence of allergies and asthma in both males and females. Departmental incidence of left-handedness ranged from a low of 7.5% (Microbiology) to a high of 21.7% (Law).     

Gender differences in smoking: A longitudinal study of beliefs predicting smoking in 11–15 year olds

This longitudinal study investigated differences in beliefs and perceived behavioural control between smokers and non-smokers in a large sample of adolescents. Positive and negative instrumental beliefs, normative beliefs, perceived behavioural control (PBC) and smoking status were assessed in the same participants at 11, 13 and 15 years of age. Prospective analyses among non-smokers revealed that for boys, negative instrumental beliefs in non-smokers at age 11 predicted smoking at age 15 years. For girls, normative beliefs and PBC in non-smokers at age 11 predicted smoking status at age 13; normative beliefs at age 11 predicted smoking at age 15; and positive instrumental beliefs and normative beliefs at age 13 predicted smoking status at age 15. Cross-sectional data revealed that smokers were significantly more likely than non-smokers to endorse positive instrumental beliefs, less likely to agree with negative instrumental belief items, more likely than non-smokers to perceive social pressure to smoke, and less likely to report control over smoking, and that female smokers reported less control over smoking and fewer negative instrumental beliefs than all other groups including male smokers at age 13. The need for belief-based preventative interventions that are age- and gender-relevant is discussed.
