Associations between psychological characteristics and indicators of metabolic syndrome among Chinese adults

Current knowledge about the relationship between psychological characteristics and metabolic syndrome (MetS) components is limited in Asian populations. The purpose of this study is to investigate linkages between physiological markers of MetS and life satisfaction, hostility, and depression in Chinese adults. Secondary analyses were conducted using cross-sectional data from parents of randomly selected middle school students participating in a pilot study in Qingdao, China. Among 440 parents who consented to participate (237 women, 203 men), 368 provided valid responses in all three categories of psychological characteristics, and only those subjects were included in these analyses. General linear models and logistic regressions were run separately by gender, controlling for covariates. Among women, life satisfaction was inversely associated with triglyceride levels (p = .04), LDL-C (p < .01), risk of hypertriglyceridemia (OR[.53], p < .01), HDL-C (OR[.78], p = .03), and MetS (OR[.52], p = .03). No associations were found between life satisfaction and any psychological characteristics among men. Among women, hostility was positively associated with triglyceride level (p = .04) and risk of hypertriglyceridemia (OR[2.12], p < .05). Among men, hostility was positively associated with waist circumference (p = .04), waist-hip ratio (p < .05), and fasting plasma insulin (p < .01). Depression was not associated with any physiological measurement in either gender. These findings indicate that relationships exist between certain psychological characteristics and physiological indicators of MetS among Chinese adults, although there may be important differences between genders.     

A Child Mourns the Family He Cannot Come From1

ABSTRACT

This article investigates the clinical material from the analysis of a young adolescent who was conceived using artificial reproduction techniques (ART). After reviewing the scant literature regarding how a child is conceived through the use of ART, the use of the term birth other is employed to understand this child’s longstanding sadness and sense of isolation. The material from his analysis demonstrates that the meaning of birth other as Eherensaft suggested (2005, 2007) is not the only meaning that an individual can assign to his experience. This child created a fantasy of a family from which he felt excluded because his parents had birth other families within which they were conceived. The material indicated that his attempt at mourning his lack of a genetically based family in a way that not even adopted children often mourn, occurred only in an unconscious manner, inhibiting him from focusing on more age-appropriate concerns. The psychological issues that he brought to his analysis clearly reflected the complexity of the circumstances of his birth and that he felt he existed outside of a family that he could identify with.     

Pereboom on the Frankfurt cases

According to the principle of alternative possibilities (PAP), a person is morally responsible for what he has done only if he could have done otherwise. In what follows, I want to defend this principle against an apparent counterexample offered recently by Derk Pereboom (Living without free will, 2001; Midwest Studies in Philosophy, 29:228?C247, 2005). Pereboom??s case, a variant of what are known as ??Frankfurt cases,?? is important for it attempts to overcome a dilemma posed for earlier alleged counterexamples to PAP. However, I will argue that by paying closer attention to the details of Pereboom??s example, we see that his example fails to show a way between the horns of the dilemma posed for the earlier Frankfurt examples.     

Emotional Dysregulation and Interpersonal Difficulties as Risk Factors for Nonsuicidal Self-Injury in Adolescent Girls

The purpose of this study was to examine a model of factors that place psychiatrically hospitalized girls at risk for non-suicidal self-injury (NSSI). The role of familial and peer interpersonal difficulties, as well as emotional dysregulation, were examined in relationship to NSSI behaviors. Participants were 99 adolescent girls (83.2% Caucasian; M age = 16.08) admitted to a psychiatric hospital. Structural equation modeling indicated the primacy of emotional dysregulation as an underlying process placing adolescents at risk for NSSI and mediating the influence of interpersonal problems through the family and peer domains. When family and peer relationships were characterized by conflict and lack of support for managing emotions, adolescents reported more dysregulated emotion processes. Family relational problems were directly and indirectly related to NSSI through emotional dysregulation. The indirect processes of peer relational problems, through emotional dysregulation, were significantly associated with NSSI frequency and severity. The findings suggest that the process by which interpersonal difficulties contribute to NSSI is complex, and is at least partially dependent on the nature of the interpersonal problems and emotion processes.     

What are the shapes of response time distributions in visual search?

Many visual search experiments measure response time (RT) as their primary dependent variable. Analyses typically focus on mean (or median) RT. However, given enough data, the RT distribution can be a rich source of information. For this paper, we collected about 500 trials per cell per observer for both target-present and target-absent displays in each of three classic search tasks: feature search, with the target defined by color; conjunction search, with the target defined by both color and orientation; and spatial configuration search for a 2 among distractor 5s. This large data set allows us to characterize the RT distributions in detail. We present the raw RT distributions and fit several psychologically motivated functions (ex-Gaussian, ex-Wald, Gamma, and Weibull) to the data. We analyze and interpret parameter trends from these four functions within the context of theories of visual search.     

Temporal coordination and adaptation to rate change in music performance

People often coordinate their actions with sequences that exhibit temporal variability and unfold at multiple periodicities. We compared oscillator- and timekeeper-based accounts of temporal coordination by examining musicians' coordination of rhythmic musical sequences with a metronome that gradually changed rate at the end of a musical phrase (Experiment 1) or at the beginning of a phrase (Experiment 2). The rhythms contained events that occurred at the same periodic rate as the metronome and at half the period. Rate change consisted of a linear increase or decrease in intervals between metronome onsets. Musicians coordinated their performances better with a metronome that decreased than increased in tempo (as predicted by an oscillator model), at both beginnings and ends of musical phrases. Model performance was tested with an oscillator period or timekeeper interval set to the same period as the metronome (1:1 coordination) or half the metronome period (2:1 coordination). Only the oscillator model was able to predict musicians' coordination at both periods. These findings suggest that coordination is based on internal neural oscillations that entrain to external sequences.     

Distinguishing blocking from attenuation in visual selective attention

Sensory information must be processed selectively in order to represent the world and guide behavior. How does such selection occur? Here we consider two alternative classes of selection mechanisms: In blocking, unattended stimuli are blocked entirely from access to downstream processes, and in attenuation, unattended stimuli are reduced in strength but if strong enough can still access downstream processes. Existing evidence as to whether blocking or attenuation is a more accurate model of human performance is mixed. Capitalizing on a general distinction between blocking and attenuation-blocking cannot be overcome by strong stimuli, whereas attenuation can-we measured how attention interacted with the strength of stimuli in two spatial selection paradigms, spatial filtering and spatial monitoring. The evidence was consistent with blocking for the filtering paradigm and with attenuation for the monitoring paradigm. This approach provides a general measure of the fate of unattended stimuli.     

In Sync and in Control: A Meta‐Analysis of Parent–Child Positive Behavioral Synchrony and Youth Self‐Regulation

A growing body of research has highlighted the connection between parent–child positive behavioral synchrony and youth self‐regulation; however, this association has yet to be the focus of a meta‐analytic review. Therefore, the present meta‐analysis aimed to estimate the magnitude of the relation between parent–child positive behavioral synchrony and youth self‐regulation and to identify moderator variables that can explain the variability in the degree of this association across the extant literature. A thorough literature search of two major databases, in addition to scanning the reference sections of relevant articles, yielded a total of 10 peer‐reviewed articles (24 effect sizes, 658 children) that were eligible for inclusion in the current meta‐analysis. Results from the overall mean effect size calculation using a random‐effects model indicated that parent–child positive behavioral synchrony was significantly, positively correlated with youth self‐regulation and the effect size was medium. Children's ages at the time of synchrony and self‐regulation measurements, as well as parent gender, served as significant moderator variables. Findings from the present meta‐analysis can help to refine existing theoretical models on the role of the parent–child relationship in youth adjustment. Prevention and intervention efforts may benefit from an increased emphasis on building parent–child positive behavioral synchrony to promote youth self‐regulation and thus children's overall well‐being.
