Psychosocial factors as longitudinal predictors of bulimic symptomatology among female collegiate athletes

ObjectivesThis study examined the within-variable stability and prospective cross-lagged pathways between body satisfaction, negative affect, self-reported intentions to engage in dietary restraint, and bulimic symptomatology among female collegiate athletes in weight-sensitive sports.DesignThis study employed a cross-lagged longitudinal design.MethodFemale collegiate gymnasts, swimmers, and divers (n = 325) completed paper-pencil survey batteries at the beginning (Time 1) and end (Time 2) of their 5-month athletic season, including measures of body satisfaction, intentions to engage in dietary restraint, negative affect, and bulimic symptomatology.ResultsFrom Time 1 to Time 2, stability coefficients were highest for intentions to engage in dietary restraint and bulimic symptomatology. Significant cross-lagged relations revealed that Time 1 body satisfaction predicted a decrease in Time 2 negative affect, Time 1 bulimic symptomatology predicted a decrease in Time 2 body satisfaction, and Time 1 negative affect predicted a decrease in Time 2 intentions to engage in dietary restraint.ConclusionsThe relative stability of intentions to engage in dietary restraint and bulimic symptomatology suggests that certain disordered eating behaviors may become more resistant to change over the course of an athletic season and solidify while competing in college. The cross-lagged associations demonstrate the importance of targeting body satisfaction, negative affect, and bulimic behaviors when designing interventions for female collegiate athletes, and implementing such programs at the beginning of an athletic season. Risk factors for bulimic symptomatology should be examined over a time period longer than one athletic season and during transitional experiences (e.g., high school to college sports).     

Subtyping eating disordered patients along drive for thinness and depression

Subtyping individuals who binge eat by “diet-DT” and “depression” has yielded two valid and clinically useful subtypes that predict eating severity, comorbid psychopathology and outcome. The present study aimed to find four subtypes based on these dimensions and test their validity. Besides, it explored the distribution of eating disorder (ED) diagnoses across subtypes given their known heterogeneity, crossover and binge-eating fluctuation.Cluster analysis grouped 1005 consecutively admitted ED adult women into four subtypes, those previously described “DT” (22%), “DT-depressive” (29%), and “mild DT” (25%) and “depressive-moderate DT” (24%). Overall “mild DT” presented lower and “DT-depressive” greater eating and comorbid psychopathology than the rest, whereas “pure DT” and “depressive-moderate DT” presented no differences on bulimic symptoms but in psychopathology (p < .01). Finally, while BN-P patients were mostly and similarly distributed in the “DT” and “DT-depressive” subtypes than in the other, AN were in the new “mild DT” and “depressive-moderate DT” (p < .01). However, BN-NP, BED and EDNOS were similarly represented across subtypes.Results are discussed with regard to 1) the newly emerged subtypes that may explain cases in which DT prevents or does not predict binge eating; 2) the confluence of DT-depression that signaled greater eating and comorbid pathology, particularly self-control problems; 3) ED-DSM-diagnostic criteria.     

Distress tolerance and early adolescent externalizing and internalizing symptoms: The moderating role of gender and ethnicity

A large body of research has examined the development of internalizing and externalizing symptoms in childhood and early adolescence. Notably, there is significant concomitant impairment associated with early adolescent symptomatology, as well as association of these symptoms with future development of psychopathology, poor physical health, self-destructive thoughts and behaviors, criminal behavior, and HIV risk behaviors. Drawing on negative reinforcement theory, the current study sought to examine the potential role of distress tolerance, defined as the ability to persist in goal-directed activity while experiencing emotional distress, as a potential mechanism that may underlie both internalizing and externalizing symptoms among 231 Caucasian and African American youth (M age = 10.9 years; 45.5% female; 54.5% Caucasian ethnicity). A series of regressions resulted in significant moderated relationships, such that low distress tolerance conferred increased risk for alcohol use among Caucasians, delinquent behavior among African Americans, and internalizing symptoms among females. Clinical implications, including the potential role of negative reinforcement models in early intervention with young adolescents, are discussed.     

Where has all the inhibition gone? Insights from electrophysiological measures into negative priming without probe distractors

Responses to probe targets that have been distractors in a prime display are slower than responses to unrepeated stimuli, a finding labeled negative priming (NP). However, without probe distractors the NP effect usually diminishes. The present study is the first to investigate ERP correlates of NP without probe distractors to shed light on the processes underlying NP. Based on existing findings in the field, we analyzed two ERP correlates that have been associated with the visual NP effect so far, namely the N200 and the P300. As expected, no behavioral NP effect as well as no N200 modulation emerged. However, the P300 component was enhanced when a prime distractor was repeated as the probe target. This effect is interpreted as reflecting automatic retrieval of the prime episode occurring independently of the presence of probe distractors.     

Freeze or flee? Negative stimuli elicit selective responding

Humans preferentially attend to negative stimuli. A consequence of this automatic vigilance for negative valence is that negative words elicit slower responses than neutral or positive words on a host of cognitive tasks. Some researchers have speculated that negative stimuli elicit a general suppression of motor activity, akin to the freezing response exhibited by animals under threat. Alternatively, we suggest that negative stimuli only elicit slowed responding on tasks for which stimulus valence is irrelevant for responding. To discriminate between these motor suppression and response-relevance hypotheses, we elicited both lexical decisions and valence judgments of negative words and positive words. Relative to positive words (e.g., kitten), negative words (e.g., spider) elicited slower lexical decisions but faster valence judgments. Results therefore indicate that negative stimuli do not cause a generalized motor suppression. Rather, negative stimuli elicit selective responding, with faster responses on tasks for which stimulus valence is response-relevant.     

Wayne Martin on judgment

Wayne Martin’s Theories of Judgment marks a significant advance in the philosophical analysis of judgment. He understands that the domain of judgment is so large that it allows only a selective treatment. We can expand Martin’s insight by acknowledging that this domain is, in fact, hypercomplex and therefore unsurveyable in Wittgenstein’s sense. Martin’s treatment of judgments can, however, be extended in a number of directions. Of particular importance is it to understand the linguistic aspect of theoretical judgments, the challenges to the synthetic conception of judgment constituted not only by existential, but also by impersonal and negative judgments, and the exploration of the links between the notions of judgment and truth.

The Structure and Stability of Subjective Well-Being: a Structure Equation Modelling Analysis

The purpose of the study is to test the structure and the stability of Subjective Well-Being (SWB), measured through cognitive and affective self-report measures, in global and specific levels of analysis. A sample of 303 adult students was collected and replicated in a 2 month interval. The best model of SWB shows an intercorrelated four-factor structure—Satisfaction with Life, Negative Affect, Positive Affect and Global Subjective Well-being. Results suggest that Global Happiness and Global Satisfaction are measuring the same aspect of SWB. All measures of SWB, in study, show good construct validity and reliability in a 2 month replication. Positive and Negative Affect are significantly weakly correlated. Positive Affect is the most stable variable of SWB, in a short-term interval. Researchers must be aware of the issues related to the measurement of SWB as the order of the items in a questionnaire and the implications of using global or specific measures, cognitive or affective dimensions of the concept, that represent different aspects of the concept. Further study is needed to analyse the structure of SWB with different measures and the relationship between its components.

Positive priming: Locations containing relevant information are labeled accordingly

Individuals engaged in a location task where the relevancy status [relevant (stimulus) vs irrelevant (distractor) information] of these locations was reversed from one trial (prime) to the next (probe). The results produced by these reversals (Distractor-to-Stimulus and Stimulus-to-Distractor) indicated that both stimulus and distractor items are given relevancy status labels which participate in the future processing at the labeled locations. These findings support the view that selective processing involves both ‘facilitatory' and ‘inhibitory' components. Further, unlike identity tasks, the data indicated that neither the formation nor the subsequent use of these ‘location' labels (stimulus or distractor) is related to the presence of a response conflict.PsycINFO classification: 2330; 2340     

Negative truths and truthmaker principles

This paper argues that a consideration of the problem of providing truthmakers for negative truths undermines truthmaker theory. Truthmaker theorists are presented with an uncomfortable dilemma. Either they must take up the challenge of providing truthmakers for negative truths, or else they must explain why negative truths are exceptions to the principle that every truth must have a truthmaker. The first horn is unattractive since the prospects of providing truthmakers for negative truths do not look good neither absences, nor totality states of affairs, nor Graham Priest and J.C. Beall’s ‘polarities’ (Beall, 2000; Priest, 2000) are up to the job. The second horn, meanwhile, is problematic because restricting the truthmaker principle to atomic truths, or weakening it to the thesis that truth supervenes on being, undercuts truthmaker theory’s original motivation. The paper ends by arguing that truthmaker theory is, in any case, an under-motivated doctrine because the groundedness of truth can be explained without appeal to the truthmaker principle. This leaves us free to give the ommonsensical and deflationary explanation of negative truths that common-sense suggests.
