Associations between Race and Eating Disorder Symptom Trajectories in Black and White Girls

Epidemiological research suggests racial differences in the presentation of eating disorder symptoms. However, no studies have examined associations between race and eating disorder symptom trajectories across youth and adolescence, which is necessary to inform culturally sensitive prevention programs. The purpose of the current study was to examine the trajectories of eating disorder symptoms from childhood to young adulthood and to examine whether race was associated with trajectory group membership. Data were drawn from 2,305 Black and White girls who participated in a community-based longitudinal cohort study (Pittsburgh Girls Study) examining the development of psychopathology. The child and adult versions of the Eating Attitudes Test assessed self-reported eating disorder symptoms at six time points between ages 9 and 21 years. Growth mixture modeling was used to examine developmental trajectories of dieting, bulimia/food preoccupation, and total eating disorder symptom scores. Given potential confounds with race and disordered eating, financial strain (i.e., receiving public assistance) and weight were included as covariates. Four to six distinct developmental patterns were found across eating disorder symptoms, including none, increasing, decreasing, or increasing-decreasing trajectories. Black girls had a greater likelihood of being in the decreasing trajectories for dieting, bulimia/food preoccupation, and total eating disorder symptom scores. White girls were more likely to follow increasing trajectories of dieting and total eating disorder symptom scores compared to Black girls. These results highlight the importance of examining the influence of racial background on eating disorder symptoms and the potential need for differences in the timing and focus of prevention interventions in these groups.     

Autonomic conditioning to monetary and social stimuli and aggression in children

Poor conditioning to punishment, such as loud tones or electric shock, has been proposed as an important factor involved in the etiology of aggressive and psychopathic behavior. However, it is not known whether the association holds when monetary or social stimulus is used as the unconditioned stimulus, and if aggressive individuals also have impaired conditioning to rewards. In this study, skin conductance responses in a conditioning task involving both monetary/social reward and punishment as unconditioned stimuli were assessed in 340 male and female 8‐ to 9‐year‐old children from the community. Children reported their reactive and proactive aggression using the Reactive and Proactive Aggression Questionnaire (RPQ; Raine et al., 2006). Results showed that monetary/social reward and punishment were effective in eliciting physiological classical conditioning in children, and that reduced reward conditioning was associated with high levels of proactive aggression in particular. Findings highlight the importance of distinguishing between reactive and proactive aggression when examining antisocial behavior in children, and suggest that reward‐oriented treatment programs may not be effective for children with more proactive, instrumental aggressive behavior.

     

Quine's Naturalism and Behaviorisms

This paper investigates the complicated relations between various versions of naturalism, behaviorism, and mentalism within the framework of W. V. O. Quine's thinking. It begins with Roger Gibson's reconstruction of Quine's behaviorisms and argues that it lacks a crucial ontological element and misconstrues the relation between philosophy and science. After getting clear of Quine's naturalism, the paper distinguishes between evidential, methodological, and ontological behaviorisms. The evidential and methodological versions are often conflated, but they need to be clearly distinguished in order to see whether Quine's argument against mentalism is cogent. The paper argues that Quine's naturalism supports only the weakest version of behaviorism, that is, the evidential one, but this version is compatible with mentalistic semantics. Quine's opposition to mentalism is an overreaction against the behaviorist camp. By contrast, Jerry Fodor's objection to José Luis Bermúdez is an overreaction from the opposite direction.     

延迟间隔和提取条件对短时错误记忆的影响

采用短时DRM迫选任务,探讨提取条件和延迟间隔对短时错误记忆的影响,以进一步考察短时错误记忆的产生机制。结果发现,短时错误记忆的产生主要源于提取时对存贮细节通达的缺失。在无有效提取线索的条件下,延迟间隔能够增加错误记忆率;而有效提取线索存在时,真实记忆痕迹的可通达性增加能够极大避免错误记忆的产生,延迟间隔的作用则不显著。该实验的结果是对错误记忆理论解释的一种补充。     

The Relationship Between Racial Identity Status Attitudes and Acculturation Among Chinese and Korean Americans: A Criterion Profile Analysis

This study tested the relationship between racial identity and acculturation among 223 Asian Americans self‐identifying as Chinese American or Korean American. Findings showed within‐group variations among the study participants with regard to their racial identity status attitudes and acculturation. Using criterion profile analysis, the authors found 2 distinctive criterion profiles of racial identity status attitudes that significantly related to higher levels of acculturation among Chinese American and Korean American participants. Implications for multicultural counseling, racial identity, and acculturation research are discussed. Este estudio puso a prueba la relación entre identidad racial y aculturación entre 223 individuos asiático‐americanos que se identifican a sí mismos como chino‐americanos o coreano‐americanos. Los resultados mostraron variaciones dentro del miso grupo entre los participantes del estudio en cuanto a su aculturación y sus actitudes hacia el estatus de su identidad racial. Usando un análisis de perfil de criterio, los autores encontraron 2 perfiles de criterio distintivos para las actitudes hacia el estatus de identidad racial que estaban relacionados significativamente con niveles más altos de aculturación entre los participantes chino‐americanos y coreano‐americanos. Se discuten las implicaciones para investigaciones sobre consejería multicultural, identidad racial y aculturación.     

Burger or yogurt? Indulgent consumption in impression management contexts

We conducted three studies to investigate indulgent choice in settings with and without impression management by public–private manipulation with evaluation. Study 1 showed that the participants were less indulgent under public scrutiny due to the employment of impression management. Study 2 focused on the impression management context to test the moderate effect of self‐consciousness in two impression managed contexts. Study 3 focused on context without impression management to test the moderate effects of self‐awareness on choices. We found that depending on differences in primed personality, individuals tended to make choices other than those they favoured privately when anticipating that others might form impressions of them based on the decisions made. The findings of all three studies support our basic prediction that people are less indulgent under impression management and suggest that people tend to manage their impression by eating healthier (less indulgently) in public.

Factors Moderating Children's Adjustment to Parental Separation: Findings From a Community Study in England

Research findings show that there is marked variability in children's response to parental separation, but few studies identify the sources of this variation. This prospective longitudinal study examines the factors modifying children's adjustment to parental separation in a community sample of 5,635 families in England. Children's behavioral/emotional problems were assessed when children were aged 47 and 81 months; marital quality, maternal depression, socioeconomic circumstances, and demographic variables were assessed prior to the separation from maternal report. Results indicated that 346 mothers separated from their partners in the 3-year period. Preseparation differences were found for measures of family process and parent risk factors, with effect sizes ranging from small to trivial. Parental separation was associated with a significant but modest increase in behavioral/emotional problems, independent of marital quality, maternal depression, socioeconomic circumstances, and demographic variables. Moderation analyses showed that children of cohabiting parents had a greater increase in adjustment problems following parental separation than children of married parents. Further research elucidating the factors that moderate children's adjustment to parental separation is needed to improve our understanding of who may most likely benefit from preventive interventions.     

Gaze allocation in a dynamic situation: effects of social status and speaking

Human visual attention operates in a context that is complex, social and dynamic. To explore this, we recorded people taking part in a group decision-making task and then showed video clips of these situations to new participants while tracking their eye movements. Observers spent the majority of time looking at the people in the videos, and in particular at their eyes and faces. The social status of the people in the clips had been rated by their peers in the group task, and this status hierarchy strongly predicted where eye-tracker participants looked: high-status individuals were gazed at much more often, and for longer, than low-status individuals, even over short, 20-s videos. Fixation was temporally coupled to the person who was talking at any one time, but this did not account for the effect of social status on attention. These results are consistent with a gaze system that is attuned to the presence of other individuals, to their social status within a group, and to the information most useful for social interaction.
