Moderators of the association between exercise identity and obligatory exercise among participants of an athletic event

Previous research has connected exercise identity with obligatory exercise, yet to date no empirical studies have identified moderator variables of this association. The current study included participants of an athletic event (full marathon, n = 582; half marathon, n = 1,106; shorter distance, n = 733) who completed questionnaires about exercise behaviors, obligatory exercise, and internalization of both the thin-ideal and athletic-ideal body shapes. General linear model analyses were conducted to examine the exercise identity–obligatory exercise relationship; moderator variables included gender, internalization of the thin-ideal body shape, and internalization of the athletic-ideal body shape. After controlling for the effects of body mass index, age, and distance group, the three-way interaction of exercise identity, gender, and internalization of the athletic-ideal body shape predicted obligatory exercise. Findings suggest that women who report high identification with exercise and high value on having an athletic physique may be vulnerable to obligatory exercise.     

Low Self-Esteem as a Risk Factor for Loneliness in Adolescence: Perceived - but not Actual - Social Acceptance as an Underlying Mechanism

Low self-esteem has been shown to relate to concurrent and later feelings of loneliness in adolescence. However, it remains unclear why low self-esteem puts adolescents at risk for experiencing loneliness. Further, longitudinal research on the direction of effects between loneliness and self-esteem is virtually non-existent. The present study aims to fill these gaps in the literature. First, the direction of effects between loneliness and self-esteem was investigated in two independent longitudinal studies: a five-wave study sampling Dutch adolescents (M age?=?15.22 years at T1; 47 % female; N?=?428) and a three-wave study sampling Belgian adolescents (M age?=?14.95 years at T1; 63 % female; N?=?882). Second, the underlying role of social acceptance was investigated in the latter sample by applying a multi-method approach that included actual (i.e., peer-reported) and perceived (i.e., self-reported) social acceptance. Results indicated that self-esteem and loneliness influenced one another in a reciprocal manner. Furthermore, the dominant path from self-esteem to loneliness was partially mediated by perceived—but not actual—social acceptance. The importance of distinguishing actual from perceived social acceptance is discussed, and suggestions for future research are outlined.     

The Role of Social Presence in Interactive Agent-Based Persuasion

This investigation examines the extent to which interactive social agent technology can influence social presence, information processing, and persuasion. Specifically, it looks at how interactive media using virtual agents can increase the sensation of social presence, or the extent to which a person feels “with” a mediated being. Using logic based on the Heuristic Systematic Model (HSM), social presence is posited to impact indicators of heuristic and systematic processing, leading to changes in attitude and intention toward a health issue. A 2 × 2 between subjects experiment was conducted (N = 125) with manipulations of interactivity (interactive or not) and source attractiveness (attractive or unattractive). Results of causal model tests suggest that interactive agents facilitate social presence leading to increased message processing, which in turn affects both attitude and behavioral intentions toward the issue of healthy blood pressure. Contrary to expectations, however, social presence with an unattractive source did not impede attitude and intentions. These findings are interpreted in light of presence, new media, and HSM scholarship.     

Randomized Controlled Trial Testing the Effectiveness of a Depression Prevention Program (‘Op Volle Kracht’) Among Adolescent Girls with Elevated Depressive Symptoms

Depression rates rise dramatically from the early to late adolescence. Especially young adolescent girls with elevated depressive symptoms are at high risk for developing a depression during adolescence or adulthood. Therefore, the prevention of depression is important especially in this high-risk group. The aim of the present study was to examine the effectiveness of the Cognitive Behavioral Therapy (CBT) component of the depression prevention program ‘Op Volle Kracht’ (OVK) among Dutch adolescent girls with elevated depressive symptoms. In total, 102 adolescent girls (11–15 years) in the first and second year of secondary school participated in this study. The girls in the experimental group (n?=?50) followed the eight CBT-lessons of OVK and reported depressive symptoms 1 week prior to the start of the lessons, after every lesson, at one-month and 6-months follow-up. The girls in the control group (n?=?52) exclusively reported depressive symptoms at the same time points. Latent Growth Curve Modeling showed that the decrease in depressive symptoms was significantly larger for girls in the experimental group compared to the girls in the control group. Furthermore, it was found that at 6-months follow-up, the girls in the experimental group had significantly lower levels of depressive symptoms compared to the girls in the control group. These findings indicate that the CBT-component of OVK effectively reduces depressive symptoms in short term and possibly prevents the development of a clinical depression.     

Order of question presentation and correlation between judgments of comparative and own risk

Unrealistic optimism is often assessed using a single question asking for an estimate of comparative risk. However, it has been proposed that individuals treat such a question essentially as though it were only about their own risk. This proposal leads to the prediction that, when the questions about own risk and comparative risk are asked in sequence, the correlation between the resulting estimates should be lower if the question about own risk comes first than if the question about comparative risk comes first. This prediction was tested using a student sample (N=68). Participants answered the two types of question in sequence, with order of presentation being counterbalanced. Results were in accord with the prediction. Possible reasons are advanced for individuals' answering questions about comparative risk as if the questions concerned their own risk.     

A Grand Theory and a Small Social Scientific Community: Niklas luhmann in Slovenia

We analyse the reception of Niklas Luhmanns social metatheory in Slovenian social. The first part outlines the intellectual climate that prevailed in the decade before the post-socialist transition. The decline of the previously dominant Marxist ideology created space for other social theories. Luhmanns ideas were the most prominent among social macro theories in the initial phase. The second part describes variations in the reception of his ideas. The initial affirmative approach was upgraded by a number of more selective and critical approaches. The third part shows that, although his ideas are no longer quite so prominent, his work is both well recognized and firmly embedded in Slovenian social thought.     

Millisecond interval timer and auditory reaction time programs for the IBM PC

Many types of behavioral research require the determination of elapsed time, for example to establish interstimulus intervals and to measure reaction time. The use of an IBM PC for on-line control of such applications is limited by the poor timing resolution ordinarily available. The IBM BIOS time information that is used for the BASIC TIMER function can result in interval timing errors as great as 110 msec. A machine language subroutine is described that can provide 1-msec accuracy. A BASIC program is also described that employs this subroutine to measure auditory reaction time.     

THE FAILURE OF FEEDBACK ON ALCOHOL IMPAIRMENT TO REDUCE IMPAIRED DRIVING

We examined the effects of rules to govern drinking, individual feedback on blood alcohol concentration (BAC), and public posting of group data on impaired driving on the incidence of impaired driving. Level of impairment was determined from breath samples taken from tavern patrons. Following baseline, an intervention package consisting of (a) cards to guide patrons in pacing their drinking to stay under the legal limit, (b) individual feedback on BAC, and (c) posted group feedback on the percentage of patrons driving while impaired the preceding week was introduced in two taverns. Results indicated that the intervention package did not reduce the percentage of impaired drivers departing either tavern. The addition of a brief intensive police enforcement program directed at impaired driving produced a short-term reduction in impaired driving.     

MOVEMENT SUPPRESSION TIME-OUT FOR UNDESIRABLE BEHAVIOR IN PSYCHOTIC AND SEVERELY DEVELOP MENTALLY DELAYED CHILDREN

The effects of a movement suppression time-out, which involved punishing any movement or verbalization while a client is in the time-out area, were evaluated in four experiments. The first experiment examined the effects of a DRO procedure and movement suppression plus DRO in suppressing self-injurious behavior in a psychotic child in three different situations. In Experiment 2, the results of the previous experiment were replicated with two dangerous behaviors in a second psychotic child. In a third experiment, movement suppression plus DRO was compared with contingent restraint in reducing inappropriate poking behavior in two settings. The movement suppression procedure eliminated poking whereas contingent restraint had little effect. In the final experiment, movement suppression time-out alone was compared with exclusionary time-out alone and simple corner time-out alone. Self-stimulation occurred at high levels during the exclusionary and simple corner time-out procedures. Self-stimulation was either suppressed or reduced during movement suppression time-out. The movement suppression time-out procedure produced a larger reduction in the target behavior in all three children. The effectiveness of the movement suppression procedure was explained in terms of the suppression of self-stimulation while the time-out procedure was being applied.     

Screening-off and The Levels of Selection

In The Levels of Selection (Brandon, 1984), Robert Brandon provides a suggestive but ultimately unsuccessful attempt to use the probabilistic notion ofscreening off in providing a schema for dealing with an aspect of the units of selection question in the philosophy of biology. I characterize that failure, and suggest a revision and expansion of Brandon's account which addresses its key shortcoming.
