The Impact of the Testing Environment on Affective Changes Following Acute Resistance Exercise

Research has demonstrated the anxiolytic and affective changes following resistance exercise. However, several studies have allowed the participants to leave the testing facility and return at a later time to complete psychological assessments. This weakens internal validity, making it impossible to interpret findings as due to exercise per se. To address this issue, 23 male participants were randomly assigned to either a “stay” or “go” group. Within each group, all participants completed a non-exercise control session and a weight-training session based on 50% of their one repetition maximum for each of five exercises. All participants remained in the laboratory for 60 minutes following each session, at which time only those in the “go” group left the laboratory and returned at 90 and 120 minutes for their remaining affective assessments. The results indicate that despite transient disruptions in mood, an acute bout of resistance exercise results in positive psychological changes that occur within 60 minutes after completion of the exercise session and which persist up to 120 minutes post-exercise. Allowing participants to leave the laboratory or requiring them to remain in the testing environment was found to lead to different patterns of affective responses during the post-exercise assessment period. Future researchers must take into account such methodological issues when designing acute exercise studies requiring extended periods of post-exercise assessment.     

Differences Between High- and Low-Confident Football Players on Imagery Functions: A Consideration of the Athletes' Perceptions

Abstract

Over the years it has been proven that the use of imagery can be a highly effective performance-enhancement technique in sport and that confidence is the most consistent psychological construct in distinguishing highly successful athletes from less successful ones. The purpose of this study was to investigate the relationship between imagery use and confidence by high- and low-confident athletes. Recent research has suggested and shown that different athletes use the same image for different functions. These studies question the usefulness of the Sport Imagery Questionnaire (SIQ) as it consists of 30 images that comprise 5 functions. In this study, an original and a modified version of the SIQ were used. The modified SIQ took into account that different athletes could use the same image for different functions as it computed the SIQ function scores according to the athletes' perceptions. Seventy-nine male collegiate football players participated. It was found that the imagery–confidence relationship differed according to how the SIQ subscale scores were computed.     

Representing young and older adult faces: Shared or age-specific prototypes?

ABSTRACT

Young adults recognize young adult faces more accurately than older adult faces and are more sensitive to how individual young faces deviate from a norm/prototype. Here we used an adaptation paradigm to examine whether young and older adult faces are represented by separable norms and the extent to which the coding dimensions for these two categories overlap. In Experiment 1, following adaptation to oppositely distorted young and older faces (e.g., expanded young and compressed older faces), adults’ normality judgments simultaneously shifted in opposite directions for the two face categories, providing evidence for separable norms. In Experiment 2, participants were adapted to distorted faces from a single age category (e.g., compressed young); aftereffects transferred across face age but were larger for the face age that matched adaptation. Collectively, these results provide evidence that young and older faces are processed with regard to separable norms that share some underlying coding dimensions.     

Differentiating accounts of actual,suggested and fabricated childhood events using the judgment of memory characteristics questionnaire

Statement analysis procedures are used in forensic settings to classify reported events as experienced or non‐experienced. These procedures are typically validated using accounts of actual events and intentionally fabricated events. However, people can also unintentionally develop false memories. To examine whether inclusion of accounts of suggested events affects classification accuracy, we validated the judgment of memory characteristics questionnaire (JMCQ) statement analysis procedure using all three statement types. Participants attempted to recall two actual events and one suggested event from their childhood over two cognitive interviews, then intentionally fabricated an account of another childhood event. Fourteen of the 34 participants (41%) reported having experienced the suggested event. Independent raters then used the JMCQ to analyse and classify each type of statement from this participant subset. Inclusion of accounts of suggested events did not reduce classification accuracy. Raters tended to classify accounts of both fabricated and suggested events as non‐experienced. Copyright © 2010 John Wiley & Sons, Ltd.     

Achievement,affiliation, and group incentives: A test of the overmotivation hypothesis

The theory of achievement motivation (Atkinson & Raynor, 1974) is seen as an important starting point for making theoretical predictions regarding the interaction of personality and situational determinants on group processes. However, progress in this direction has been slow, possibly because group situations may lead to overmotivation. Here, persons who might be expected to excel in such situations (e.g., success-oriented persons also high in affiliation motivation) may actually perform poorly as a function of being too positively motivated. The present study is an attempt to find a priori evidence for the overmotivation hypothesis in order to facilitate progress toward a motivational theory of group activity. Male and female subjects were run in either an individual or a cooperative performance situation. The achievement, affiliative, and extrinsic incentives in these situations were examined in conjunction with relevant personality dimensions. The results lend support to the overmotivation hypothesis. Implications for group activity are discussed.     

Evaluation of a preventive intervention for a self-selected subpopulation of children

Evaluated an experimental preventive intervention developed for children who perceived their parents as problem drinkers. The 8-session program was designed to improve children's coping, self-esteem, and social competence, and modify alcohol expectancies which were specified as mediators of the effects of parental alcohol abuse on child mental health. Participants were 271 self-selected 4th-, 5th-, and 6th-grade students in 13 schools. The children were randomly assigned to treatment or delayed treatment conditions and the program was given to three successive cohorts of students. A meta-analysis across three different cohorts indicated significant program effects to improve knowledge of the program content and the use of support- and emotion-focused coping behaviors for the full sample. A slightly stronger range of effects was found for a high-risk subsample. This research was funded by the National Institute of Mental Health Grant P50-MH39246 to support a Preventive Intervention Research Center and Prevention Training Grant T32-MH18387-02.     

Sex differences, social desirability, masculinity, and the tendency to worry.

Relationships between worry and sex differences, social desirability, masculinity, and femininity were explored in this study. Data were obtained from 141 undergraduates who answered a questionnaire containing a worry scale, the Crowne-Marlowe (1964) Social Desirability Scale, the Bem (1974) Sex Role Inventory, the Trait Anxiety scale of the State-Trait Anxiety Inventory (Spielberger, Gorsuch, & Lushene, 1970), and several demographic items. Women reported significantly higher levels of worry than men did, and worry was significantly correlated with lower social desirability and with lower masculinity but not with femininity. However, multiple regression strategies revealed that sex differences in reported worry cannot be accounted for solely by variations in social desirability and masculinity. Also, sex differences in the tendency to worry were not eliminated by statistically controlling for trait anxiety, social desirability, and masculinity simultaneously.     

A qualitative and serial analysis of social problem solving in aggressive boys

Social problem solving skills in 84 elementary school aged boys were assessed to identify those responses most salient in the prediction of ratings of aggressive and socially withdrawn behavior. Aggressive and socially withdrawn boys did not differ from the control group in the number of effective first solutions generated to the hypothetical stories. The control group generated significantly more effective solutions as second alternatives to the stories than did the aggressive or socially withdrawn boys. In addition, the number of effective second responses generated significantly predicted both aggression and social withdrawal after controlling for verbal problem solving. Results are discussed in terms of differences in cognitive processes as well as implications for treatment.This research was partially supported by a grant to the first author from the Charles Rieley Armington Foundation on Values in Children.

Burden in schizophrenia caregivers: impact of family psychoeducation and awareness of patient suicidality

Family caregivers of persons with schizophrenia and other psychotic disorders experience high levels of burden. Although a number of patient and caregiver predictors of burden have been identified, little research has investigated the contributions of patient depression, suicidal ideation, and substance abuse. In addition, family psychoeducation interventions have reduced patient symptoms, as well as inpatient treatment utilization; however, it is not known whether or not these interventions reduce family burden. This study investigated predictors of family burden and tested to what degree multiple family group treatment (MFGT), relative to a standard care condition, was associated with reduced family burden. Participants were 90 outpatients with a diagnosis of schizophrenia or other psychotic disorders, and their caregivers who were enrolled in a 2 year psychoeducation intervention. The best set of predictors of burden, identified by stepwise linear regression, was young patient age, awareness of patient's suicidal ideation, and family resources. These variables accounted for 32% of the total variance in burden. Findings suggest that caregiver's awareness of patient's suicidal ideation, not patient's report of suicidal ideation; and that patient age, not duration of the illness, were significant independent predictors of burden. When compared to a standard-care condition over 2 years, MFGT did not reduce family caregiver burden. Discussions focus on the relationship between burden and its predictors, and possible reasons why MFGT did not decrease burden. Modifications are proposed that may increase the impact of MFGT.     

Psychometric properties of the Dominic interactive assessment: a computerized self-report for children

The reliability and validity of the Dominic Interactive (DI) assessment were evaluated. The DI is a computerized self-report measure for children, which assesses symptom presence for seven DSM-IV diagnoses. The participants were 322 children (169 cocaine exposed, 153 non-cocaine exposed) who were recruited at birth for a prospective longitudinal study. At 6 years of age, measures of self-report, parent report, and observational data were collected. Moderate to excellent internal consistencies on the DI were found for the total sample as well as for subsamples based on cocaine status and gender. Concurrent validity correlations between DI scales and the Child Behavior Checklist, Affect in Play Scale, a modified Conners's Teachers Rating Scale, and the Parenting Stress Index were examined. Significant relationships among scales were more apt to be among comparisons that assessed externalizing behaviors. Overall, low correlations were obtained, which are comparable to other studies that evaluate agreement between child and parent report of behaviors.
