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.     

Physician Identification and Management of Psychosocial Problems in Primary Care

Often the burden of identifying children with behavioral or developmental problems is left up to the primary care physician (PCP). However, previous literature shows that PCPs consistently underidentify children with developmental/behavioral problems in pediatric primary care. For the current study, questionnaires containing three vignettes followed by questions addressing common psychosocial problems, general questions about their practice and training, and the Physician Belief Scale were distributed to physicians. Results indicated that physicians were better at identifying severe problems, had more difficulty identifying psychosocial problems with mild symptomatology, and tended to refer to a medical specialist or mental health professional more often for severe problems, depression or a developmental problem. Physicians tended to view treating psychosocial problems favorably.     

A Confirmatory Factor-Analytic Evaluation of the Purpose in Life Test: Preliminary Psychometric Support for a Replicable Two-Factor Model

This study’s purpose was to use confirmatory factor analysis to compare published factor-analytic models of the 20-item Purpose in Life test (PIL) to identify the one that provides the best fit to the data. To date many different models have been described, with limited evidence to support whether they are replicable. This study utilized data from undergraduates (N = 620) from a medium-sized university located in the southern United States. Ten different PIL models were tested, with support found for the two-factor model (exciting life, purposeful life) of Morgan and Farsides. Recommendations and implications for research are provided.     

A preliminary study of medial temporal lobe function in youths with a history of caregiver deprivation and emotional neglect

Previous research findings have linked caregiver deprivation and emotional neglect with sensitivity to threatening cues. The present preliminary study investigated whether dysfunctions of the medial temporal lobe could underlie these associations. Using fMRI, we measured medial temporal lobe responses to emotional faces (angry, fearful, happy, neutral) among 30 youths. Eleven of the youths had a history of caregiver deprivation and emotional neglect. Attention states (i.e., attention to anger, fear, or physical attributes, or passive viewing) were systematically manipulated. Relative to comparison youths, youths with a history of caregiver deprivation and emotional neglect showed significantly greater left amygdala and left anterior hippocampus activation during the processing of threatening information. To our knowledge, these findings are the first to demonstrate altered medial temporal lobe function during the processing of threat cues in youths with a history of caregiver deprivation and emotional neglect.     

Consumer Masculinity Behavior Among College Students and Its Relationship to Self Esteem and Media Significance

The purpose of the study was to investigate male college students in the southeastern United States to identify factors associated with consumer masculinity behavior. The variables of self-esteem and media significance were tested as possible predictors of consumer masculinity behavior. A total of 219 surveys were used as the sample for this study. Pearson correlation analysis tested relationships among the variables, and linear regression was used to further test the nature of the relationships identified. Results indicated that media significance and appearance-related self-esteem were significant predictors of consumer masculinity behavior. Limitations and implications are discussed.     

Temptation Bias: Can Self-enhancement Limit the Influence of Gender Stereotypes?

Temptation bias is the tendency to see oneself as better than others at resisting temptation. To understand the influence of self-enhancement and gender stereotypes on temptation bias, 215 undergraduates from a university located in the southwest region of the United States compared their ability to resist ten sexually tempting scenarios to that of others in general, and to their romantic partner (Study 1). An additional 151 undergraduates from the same university rated their own or their partner’s ability to resist seven sexually tempting scenarios compared to other men and women (Study 2). Results revealed that temptation bias was present but reduced when romantic partners were the comparison targets; and when comparing themselves to others, women displayed temptation bias regardless of the gender of the referent while men displayed temptation bias only when comparing themselves to men.     

Relational Aggression in Mothers and Children: Links with Psychological Control and Child Adjustment

This study assesses associations between mothers’ use of relational aggression with their peers and psychological control with their children, and child adjustment in a sample of fifty U.S. mothers of elementary and middle school children. Mothers completed surveys assessing their relational aggression and psychological control. Teachers completed surveys assessing children’s externalizing behavior, internalizing symptoms, and relational aggression. Results suggest that mothers who are relationally aggressive with their peers are more likely to be psychologically controlling with their children. Results also showed that relational aggression predicted adjustment problems in youth. Relational aggression was associated with externalizing problems among boys and girls, and with internalizing problems among boys. Few gender differences in mean levels of maternal or child behaviors emerged.     

Durability,Negative Impact,and Neuropsychological Predictors of Tic Suppression in Children with Chronic Tic Disorder

Chronic tic disorders are characterized by involuntary motor and vocal tics, which are influenced by contextual factors. Recent research has shown that (a) children can suppress tics for brief periods of time, (b) suppression is enhanced when programmed reinforcement is provided for tic-free intervals, and (c) short periods of suppression do not result in a paradoxical "rebound" in tic frequency when active suppression has ceased. The current study extended existing research in three important ways. First, we examined whether tic suppression ability decreased as suppression duration increased from 5 to 25 to 40 min. Second, we examined post-suppression tic frequency to test whether longer periods of suppression were more likely to be associated with a rebound effect. Finally, we explored neuropsychological predictors of tic suppression. Thirteen children with Tourette syndrome or a chronic tic disorder completed the study. Results showed that (a) tic suppression was sustained for all of the suppression durations, (b) rebound effects were not observed following any of the suppression durations, and (c) ability to suppress was correlated with omission, but not commission errors on a continuous performance task. Implications of these findings are discussed.     

The role of interdependence and perceived similarity in depressed affect contagion

This study hypothesized that perceived similarity significantly impacts depressed affect contagion only for individuals with highly interdependent self-construals. Baseline self-construal and affect were measured. Then, after reading a vignette about a depressed or nondepressed target, affect and perceived similarity were assessed. Participants reading the depressed vignette reported higher negative affect than participants reading the nondepressed vignette. Positive affect did not differ between the two conditions. For participants exposed to the depressed vignette, the hypothesized interaction between perceived similarity and interdependence significantly predicted positive affect. It appears that participants with more interdependent self-construals were more likely to "catch" the low positive affect displayed by the depressed target only if they perceived themselves as highly similar to the target.
