Evaluating the separate and combined effects of positive and negative reinforcement on task compliance

Positive and negative reinforcement are effective for treating escape-maintained destructive behavior. The current study evaluated the separate and combined effects of these contingencies to increase task compliance. Results showed that a combination of positive and negative reinforcement was most effective for increasing compliance.     

Sustained attention and age predict inhibitory control during early childhood

Executive functioning skills develop rapidly during early childhood. Recent research has focused on specifying this development, particularly predictors of executive functioning skills. Here we focus on sustained attention as a predictor of inhibitory control, one key executive functioning component. Although sustained attention and inhibitory control have been linked in older children and adults, these links have not been well specified during early childhood. The current study examined both parent-rated and laboratory measures of sustained attention as predictors of both parent-rated and laboratory measures of inhibitory control among 3- to 6-year-olds. As expected, children with higher sustained attention abilities exhibited greater inhibitory control. Moreover, inhibitory control increased across age. These findings reveal important details about the development of sustained attention and inhibitory control during early childhood.     

Maternal positive parenting style is associated with better functioning in hyperactive/inattentive preschool children

Many preschoolers are highly inattentive, impulsive, and hyperactive; but only some are impaired in their functioning. Yet factors leading to functional impairment, above and beyond the severity of inattentive and hyperactive symptoms, have not been systematically examined. This study examined a model suggesting that after controlling for attention‐deficit/hyperactivity disorder (ADHD) symptom severity, child temperament is uniquely associated with parenting stress; that parenting stress affects parenting style, above and beyond child characteristics; that parenting style is related to the level of child impairment, above and beyond the effects of child symptoms, temperament, and parenting stress; and finally that parenting style moderates the relationship between ADHD symptom severity and child functioning. Child measures included parent‐ and teacher‐rated ADHD symptom severity, teacher‐rated temperament, and clinician‐rated functioning in a sample of 138 inattentive/hyperactive preschoolers. Maternal self‐ratings of parenting style and parenting stress were obtained. Analyses indicated that, after controlling for symptom severity, child temperament was related to maternal parenting stress, which was additionally related to both maternal parenting style and child functioning. Maternal positive parenting style moderated the relationship between ADHD symptom severity and child impairment, indicating that a positive parenting style plays a protective role in the functioning of hyperactive/inattentive preschoolers.

Specific Features of After-School Program Quality: Associations with Children’s Functioning in Middle Childhood

This longitudinal study examined associations between three after-school program quality features (positive staff–child relations, available activities, programming flexibility) and child developmental outcomes (reading and math grades, work habits, and social skills with peers) in Grade 2 and then Grade 3. Participants (n = 120 in Grade 2, n = 91 in Grade 3) attended after-school programs more than 4 days per week, on average. Controlling for child and family background factors and children’s prior functioning on the developmental outcomes, positive staff–child relations in the programs were positively associated with children’s reading grades in both Grades 2 and 3, and math grades in Grade 2. Positive staff–child relations also were positively associated with social skills in Grade 2, for boys only. The availability of a diverse array of age-appropriate activities at the programs was positively associated with children’s math grades and classroom work habits in Grade 3. Programming flexibility (child choice of activities) was not associated with child outcomes.     

The effect of state extraversion on four types of affect

The primary purpose of this study was to determine the effect of state extraversion on different types of affect. Ninety six participants were instructed to be extraverted or introverted in a 10‐minute dyadic discussion. State extraversion had a strong effect on positive affect and smaller (but still strong) effects on pleasant and activated affect, with these latter two effects almost equal in magnitude. This pattern of findings appears to increase confidence that the effect of state extraversion is genuine rather than the result of construct overlap, in that extraversion's effect on positive affect is not dominated by its effect on activated affect. No support for reward sensitivity as a potential explanatory mechanism was found. Copyright © 2009 John Wiley & Sons, Ltd.     

Induced Over-Benefiting and Under-Benefiting on the Web: Inequity Effects on Feelings and Motivations with Implications for Consumption Behavior

Inequity in its many forms has been the subject of a number of empirical research efforts. Results show that positive inequity, an over-benefited condition, and negative inequity, an under-benefited condition, have divergent effects on subsequent affects and behavioral tendencies. We embed equity treatments within a motivational structure to predict reactions to a quasi-shopping experience in which these methods operate in concert. Interaction effects—predicted by procedural justice considerations as well as instrumentally based arguments—are also tested whereby technical motivation is crossed with the equity conditions. In testing, an online experiment was created incorporating pre- and posttreatment measures. While completing a hypothetical sale, respondents received either an unanticipated, completed coupon field (the over-benefited group), an uncompleted, empty coupon field (the under-benefited group), or were not prompted with a coupon field (the control group). Results showed strong negative effects on postexposure satisfaction, intention, and desire to complete the purchase in the empty coupon field group, and similar positive effects in the completed coupon field group. Moreover, a model linking preexposure variables (expectations and technical sophistication) to postexposure measures was supported indicating carry-through effects. Lastly, procedural justice and instrumental predictions received mixed support when testing for the interaction between technical motivation and inequity. Results showed that, for those in the under-benefited group, there was only a slight tendency for those with higher levels of technical sophistication to report greater satisfaction; however a strong tendency was found for the same individuals to report a lower likelihood of completing the purchase. Implications for future research are discussed.     

Outcome of aggression affects processing and can legitimise subsequent aggression: Influence of trait aggressiveness

The present study investigated differences in processing times between positive and negative outcomes to an aggressive reaction to provocation. The effects of outcome, sex, trait aggressiveness and current mood on subsequent subject‐generated material were also examined. Fifty subjects read stories line by line on a computer screen. Reading time for the key sentence describing a positive or negative outcome to an aggressive reaction to provocation was recorded and subjects wrote a continuing sentence to half the stories. Subjects took less time to process the negative outcome. The positive outcome resulted in more subject‐generated aggression than the negative outcome. There were few sex differences but men wrote more aggressive endings than women for the stories containing physical aggression. Trait aggressiveness was correlated with producing more aggressive content in the continuing sentence for both outcomes. Feeling peaceful was correlated with producing prosocial material to neutral stories. Subjects therefore expect a negative outcome to aggressive behaviour. Reading stories which present a positive outcome to aggression increases the accessibility of aggressive cognitions. Subjects high in trait aggressiveness are not inhibited by a negative outcome.

Changes in Sexual Functioning and Mood Among Women Treated for Gynecological Cancer Who Receive Group Therapy: A Pilot Study

This study examined changes in sexual functioning and mood disturbance among women who have been treated for gynecological cancer and who participated in a 12-week group intervention for psychosexual problems. The Changes in Sexual Functioning Questionnaire (CSFQ) assessed the sexual functioning, and the Profile of Mood States (POMS) assessed the mood disturbance of 19 women at baseline who completed follow-ups conducted posttreatment and three-month posttreatment. The results showed that the women improved significantly in their CSFQ total scores after being provided with the group therapy intervention at the posttreatment assessment (p < .01), and a statistical trend (p < .10) suggested continued improvement in CSFQ total scores at the three months posttreatment follow-up. Women's POMS total mood disturbance scores improved significantly at the posttreatment assessment (p = .01), but did not show significant improvement at the 3-month posttreatment follow-up. These results suggest that this group intervention achieved its main goal in treating sexual dysfunction as well as mood disturbance, but these improvements dissipated over time and may require further intervention in order to be maintained.
