基本心理能力老化的认知机制

基本心理能力老化机制是认知老化领域研究热点之一。横断研究与追踪研究表明, 感觉功能、加工速度、工作记忆等信息加工资源的衰退导致了基本心理能力的衰退。但由于相关研究不能进行因果推论, 基本心理能力老化的认知机制尚存在争论。因此本项目拟采用实验室研究和干预实验设计, 通过操纵感觉功能(知觉压力水平)、干预加工速度与工作记忆, 考察基本心理能力的年龄差异的变化, 以期为认知老化理论的深化和拓展提供实验依据。     

How does the strength of the relationships between cognitive abilities evolve over the life span for low-IQ vs high-IQ adults?

The present study was designed to examine how the correlations between cognitive abilities evolve during adulthood. Data from 1104 participants on the French version of the Wechsler Adult Intelligence Scale-Third Edition were analyzed. The entire sample was divided into four age groups (16–24 years; 25–44 years; 45–69 years and 70–89 years), which were themselves split into two IQ-levels using the mean standard score on Vocabulary and Block Design. For every age group, the mean correlation between subtest scores of low-IQ participants was higher than that of high-IQ participants. There was also no interaction between age and IQ for the strength of subtest relationships. Indeed, the effect sizes of correlation differences between low- and high-IQ participants appeared to be relatively constant across age. A general developmental schema of how the strength of correlations between cognitive abilities of low- and high-IQ individuals evolves during the entire life span is sketched in the discussion.     

<Emphasis Type="Italic">My Way</Emphasis> and Life’s Highway: Replies to Steward,Smilansky, and Perry

I seek to reply to the thoughtful and challenging papers by Helen Steward, Saul Smilansky, and John Perry. Steward argues that agency itself requires access to alternative possibilities; I attempt to motivate my denial of this view. I believe that her view here is no more plausible than the view (which she rejects) that it is unfair to hold someone morally responsible, unless he has genuine access to alternative possibilities. Smilansky contends that compatibilism is morally shallow, and that we can see this from the “ultimate perspective.” In reply, I explore the nature of “zooming” arguments, and I contend that even from a somewhat more detached perspective, important features that distinguish us from mere animals can be discerned (even in a causally deterministic universe). Finally, I seek to address Perry’s defense of classical compatibilism. My main objection to his form of compatbilism is that agents must be construed as having a certain kind of “baggage”—even on his own account.

老年人日常认知研究评述

日常认知一直是临床心理学家和老年心理学家关注的重点之一, 日常认知的研究主要集中于概念、评估方法和工具、日常认知与智力和执行功能的关系以及相关的干预训练等方面。日常认知概念的深化和相应评估工具的出现, 推动了日常认知研究的深入发展：一方面研究者通过寻找对日常认知有重要作用的基本认知变量, 探究日常认知与智力的关系; 另一方面, 与日常认知有关的训练项目的开发也一直是研究者和老年群体关注的话题, 现有的训练研究提供了很多有启发性的结果。日常认知是老年人身心健康的重要影响因素, 对于保持或提高老年人的生活质量非常重要。     

When credibility attacks: The reverse impact of source credibility on persuasion

Recent research on the self-validation hypothesis suggests that source credibility identified after message processing can influence the confidence people have in their own thoughts generated in response to persuasive messages (Briñol, Petty, & Tormala, 2004). The present research explored the implications of this effect for the possibility that high credibility sources can be associated with more or less persuasion than low credibility sources. In two experiments, it is demonstrated that when people generate primarily positive thoughts in response to a message (e.g., because the message contains strong arguments) and then learn of the source, high source credibility leads to more favorable attitudes than does low source credibility. When people have primarily negative thoughts in response to a message (e.g., because it contains weak arguments), however, this effect is reversed—that is, high source credibility leads to less favorable attitudes than does low source credibility.     

The roles of thought suppression and metacognitive beliefs in proneness to auditory verbal hallucinations in a non-clinical sample

In a non-clinical sample (N = 751), we investigated relations among two subscales (self-reported intrusiveness of unwanted thoughts and thought suppression) of the White Bear Suppression Inventory (WBSI), metacognitive beliefs, and proneness to auditory verbal hallucinations (AVHs). Both subscales of the WBSI were found to be related to AVH-proneness and strongly positively related to metacognitive beliefs about the uncontrollability and danger of thoughts. Regression analyses were used to test models of the relations among AVH-proneness and a range of metacognitive beliefs. When the WBSI subscale relating to the self-reported intrusiveness of unwanted thoughts was controlled for, the metacognitive style that was the strongest predictor of AVH-proneness was cognitive self-consciousness. Cognitive confidence and beliefs about the uncontrollability of thoughts were also significant predictors of AVH-proneness. These findings are used to revise existing models of the relations between metacognitive beliefs and AVHs. Implications for the management of AVHs are discussed.     

Factors Associated with Relationship Satisfaction: Importance of Communication Skills

The present study aimed to investigate the association between communication skills and relationship satisfaction, after having controlled for some other important associates of relationship satisfaction, such as attachment styles and various problem-solving skills including sense of control, confidence, and attitudes of approach-avoidance. One-hundred-forty-two university students who were either currently involved in a romantic relationship, or who had a romantic relationship in the past participated in this study. As a result of hierarchical regression analysis consistent with the expectations, having secure attachment style and high self-confidence on possessed problem-solving abilities were found to be associated with the relationship satisfaction. Moreover, after controlling for the variance accounted for by these variables communication skills were still found to be associated with the relationship satisfaction. Findings were discussed in the light of the relevant literature.

Seemingly Anomalous WISC-IV Full Scale IQ Scores in the American and Canadian Standardization Samples

The American and Canadian standardization samples for the fourth edition of the Wechsler Intelligence Scale for Children were used to ascertain the prevalence of “seemingly anomalous” Full Scale IQ (FSIQ) scores for all possible sums of scaled scores combinations of the Verbal Comprehension Index, Perceptual Reasoning Index, Working Memory Index, and Processing Speed Index. About 1% of FSIQ scores in both samples were anomalous (that is, fell outside the range of the four indices). Interestingly, the prevalence of anomalous scores was higher at the extremes of the FSIQ distribution. Moreover, anomalous FSIQ scores occurring above or below the mean of the FSIQ distribution (that is, 100) were larger or smaller, respectively, than any of the four indices. Furthermore, if the range of the four indices did contain the FSIQ (the non-anomalous case), when the FSIQ was below or above 100 it tended to be located distally in the half-segment of the range furthest below or above 100, respectively. A non-technical intuitive analogy from Olympic sports and a statistical explanation for the findings are provided. Important implications for practitioners are also presented. Portions of this paper were presented March 17, 2006 at the 20th annual Joseph R. Royce Research Conference, Department of Psychology, University of Alberta, Edmonton, Alberta.     

The psychological processes underlying symptoms of thought interference in psychosis

Morrison and colleagues have proposed that auditory hallucinations are the result of cognitive intrusions being misattributed to an external source due to such thoughts being inconsistent with the person's beliefs about his or her own mental processes (metacognitive beliefs). The aim of this study was to investigate the applicability of this model to psychotic symptoms of thought interference. Fifty psychotic patients with and without thought interference were compared on (i) frequency of cognitive intrusions, (ii) metacognitive beliefs, (iii) source monitoring and (iv) appraisals of an unrelated anomalous event (a card trick). As predicted, individuals with thought interference had an increased frequency of cognitive intrusions and of maladaptive metacognitive appraisals, lower perceived cognitive control, and were more likely to endorse appraisals regarding 'permeability' of the mind, on the card trick task, in comparison to individuals without thought interference. No significant differences were found on any measure when the patient group was divided into hallucinators and non-hallucinators, once other variables were controlled for. These findings suggest that Morrison's model may be more parsimonious for symptoms of thought interference than for auditory hallucinations.
