2型糖尿病的营养干预策略

2型糖尿病的发病率日益增加,已成为影响人类健康的主要疾病之一.糖尿病的高糖、高脂状态可使活性氧化物产生增多,造成氧化应激;氧化应激与糖尿病的发生与发展密切相关,通过联合补充抗氧化微量营养素VitE、VitC、Zn及Se,以及多选用含抗氧化物食品,可有效地降低氧化应激,从而阻止或延缓糖尿病病情的进展.     

Implicit learning, thought-focused attention and obsessive-compulsive disorder: a replication and extension

Although significant empirical support exists for both cognitive and neurobiological models of obsessive-compulsive disorder (OCD), there have been few efforts to integrate findings. In this investigation, we attempted to link models by examining relationships between performance on information processing tasks posited to be markers of OCD-related neuropathology and a self-report measure of excessive thought-focused attention (cognitive self-consciousness; CSC). Congruent with predictions and prior research, OCD patients' performance was impaired in comparison to an anxious control group on the Serial Reaction Time (SRT) Task, a measure of implicit procedural learning. Following completion of the SRT, participants' awareness of the embedded stimulus pattern was assessed. As predicted, participants with OCD demonstrated superior performance on this task. Scoring on a measure of CSC correlated with performance on both tasks, although the amount of variance accounted for was modest. Evaluation of OCD symptom subgroups revealed greater procedural learning impairment in a hoarding subgroup. Implications for theory and treatment are discussed.     

Mindfulness as a means of reducing aggressive behavior: dispositional and situational evidence

Recent research and theory suggest that mindfulness, or enhanced attention and awareness in the present moment [Brown and Ryan, 2003], may be linked to lower levels of ego-involvement and, as a result, may have implications for lowering hostility and aggressive behavior. Accordingly, we conducted two studies to examine the potential aggression-mitigating role of mindfulness. In Study 1, we found that dispositional mindfulness correlated negatively with self-reported aggressiveness and hostile attribution bias. In Study 2, participants made mindful before receiving social rejection feedback displayed less-aggressive behavior than did rejected participants not made mindful. Discussion centers on potential mechanisms by which mindfulness operates to reduce aggressive behavior.     

群际宽恕的影响因素

群际宽恕(Intergroup Forgiveness)是指对曾经侵犯过本群的外群所具有的报复感、愤怒感以及不信任感的减少, 有意识地去理解、接近对方群体, 并积极地参与到对方群体中去的一种心理过程。学界对影响群际宽恕的因素进行了深入的研究, 分析了低人性化、竞争受害性、群体认同、愤怒、共情、道歉以及群体接触7个因素对群际宽恕产生的影响作用; 同时, 以影响因素的研究结论为基础, 不同的学者提出了提升宽恕水平, 缓和群体关系的干预性建议。但是, 作为一个新的研究主题, 还需要深入探讨群际宽恕的内部过程机制, 积极建立符合本土文化的干预模型。     

Happiness is an Emotion

Accounts of happiness in the philosophical literature see it as either a judgment of satisfaction with one’s life or as a balance of positive over negative feelings or emotional states. There are sound objections to both types of account, although each captures part of what happiness is. Seeing it as an emotion allows us to incorporate both features of the accounts thought to be incompatible. Emotions are analyzed as multicomponent states including judgments, feelings, physical symptoms, and behavioral dispositions. It is shown that prototypical happiness contains all these components, and each is explicated. The concept of happiness, like the concepts of other emotions, is a cluster concept. The features of such concepts are made clear. Happiness is shown to be similar to other emotions in many respects, including the phenomenon of adaptation, the “paradox of happiness,” and the existence of both paradigm and borderline instances. The account allows us to capture all that was right in earlier accounts while avoiding objections to them.     

影响群体道歉有效性的因素

影响群体道歉有效性的因素是多方面的。对侵犯群体而言, 有效的群体道歉需要在言语表达中包含承认错误、承担责任、表达懊悔、做出承诺等内容, 需要讲究群体道歉的行为策略, 同时还应该关注道歉的内部动机对语言表达与行为方式的影响。对受害群体来讲, 侵犯群体道歉的有效性在于道歉本身缓解了其愤怒情绪, 满足了其自尊和期望等心理需求, 同时还要受到他们对道歉真诚性知觉程度的影响。除此之外, 群体道歉还会受到群际关系质量、冲突程度、文化信念等外部因素的影响。在今后的研究中, 应该继续尝试整合群体道歉的过程机制, 丰富群体道歉有效性的考察指标, 发挥道歉在社会生活领域中的积极作用。     

Alcohol expectancy multiaxial assessment: a memory network-based approach

Despite several decades of activity, alcohol expectancy research has yet to merge measurement approaches with developing memory theory. This article offers an expectancy assessment approach built on a conceptualization of expectancy as an information processing network. The authors began with multidimensional scaling models of expectancy space, which served as heuristics to suggest confirmatory factor analytic dimensional models for entry into covariance structure predictive models. It is argued that this approach permits a relatively thorough assessment of the broad range of potential expectancy dimensions in a format that is very flexible in terms of instrument length and specificity versus breadth of focus.     

The influence of alcohol expectancy priming and mood manipulation on subsequent alcohol consumption

Studies showing that verbal priming can implicitly affect alcohol consumption have been used to support cognitive models of expectancies. However, because expectancy words reflect affective states as well as drinking outcomes, mediation through an affective pathway remains theoretically plausible (i.e., such words inadvertently may affect mood, which in turn influences drinking). The primary pathway was identified (and expectancy theory was tested) by comparing memory priming (using alcohol expectancy or neutral words) with mood induction (using positive or neutral music); an unrelated experiment paradigm allowed the priming manipulation to implicitly affect drinking. Men in the alcohol priming group drank significantly more than men in each of the other conditions, and, consistent with theory, men with histories of heavier drinking drank the most when primed with alcohol expectancies, indicating that expectancies can function as automatic memory processes.     

Use of the MMPI-2 in American Indians: I. Comparability of the MMPI-2 between two tribes and with the MMPI-2 normative group

The comparability of the MMPI-2 in American Indians with the MMPI-2 normative group was investigated in a sample of 535 Southwestern and 297 Plains American Indian tribal members with contrasting sociocultural and historical origins. Both American Indian tribal groups had clinically significant higher T scores (> 5 T points) on 5 validity and clinical scales, 6 content scales, and 2 supplementary scales than did the MMPI-2 normative group. There were no significant differences between the 2 tribal groups on any of the MMPI-2 clinical, content, or supplementary scales. Matching members of both tribes with persons in the MMPI-2 normative group on the basis of age, gender, and education reduced the magnitude of the differences between the 2 groups on all of these scales, although the differences in T scores still exceeded 5 T points. It appears likely that the MMPI-2 differences of these 2 American Indian groups from the normative group may reflect their adverse historical, social, and economic conditions.     

Using a modified Stroop task to implicitly discern the cognitive organization of alcohol expectancies

Alcohol expectancies have been statistically modeled as memory networks that influence future consumption. To test the organization of expectancies suggested by these models, a modified Stroop color-naming task incorporated expectancy words associated in past research with heavy and light drinking. Light and heavy drinkers ink-named expectancy targets after being cued with an alcohol beverage word or a nonalcohol beverage word. Consistent with predictions derived from statistical models, heavy drinkers displayed significant interference when arousing expectancy words had been primed by an alcohol beverage word, whereas light drinkers displayed significant interference when sedating expectancy targets had been so primed. These results reinforce the idea that mediation o falcohol use by expectancies may be implicit as well as explicit.
