心算的加工机制：来自认知神经科学的研究

心算加工分编码（表征）、运算（或提取）和反应三个阶段,这三个阶段相互影响。不同输入形式的数字表征在顶叶的不同区域完成。算术知识提取主要与左脑顶内沟有关,但当心算变得更复杂时而需要具体运算时,左脑额叶下部出现明显激活。所有与心算有关的脑区涉及大脑前额皮层和颞顶枕联合皮层的综合作用,并总体表现为左脑优势,但估算、珠心算以及某些具有特殊心算能力的人的心算还依赖视空间表征,这与右脑额顶区和楔前叶的活动有关     

心算加工的认知神经科学研究

近几年(1999-2005)有关心算加工的脑活动机制研究发现,类似九九乘法表这样的算术知识提取(如3×5)主要与左脑顶内沟有关,但当心算变得更复杂时(如26×38),左脑额叶下部出现明显激活,这表明心算与语言和工作记忆关系密切。另一方面,也存在不依赖于语言的即表现为视觉表象活动的心算,右脑的一些脑区在其中起了作用。简言之,所有与心算有关的脑区涉及到大脑前额皮层和颞顶枕联合皮层的综合作用,并总体表现为左脑优势,但具有特殊心算能力的人其心算还与右脑前额叶和颞叶内侧脑区的活动有关。     

Imagery-Enhanced Cognitive Restructuring of Hostile Beliefs: A Narrative Description

Cognitive restructuring (CR) is an efficacious intervention for reducing transdiagnostic hostility. However, evidence suggests that the efficacy of CR can be further improved. A promising candidate for improving the efficacy of CR is mental imagery. Previous work showed that enriching CR with mental imagery (I-CR) increased its efficacy in terms of reducing hostile beliefs and aggressive inclinations. In this article, we describe the rationale of the I-CR procedure, how to use it, and illustrate it with case examples. Our clinical experience underlines that imagery seems to capture both the hostile as well as helpful thoughts in a more effective way than verbal formulations. Future studies need to explore whether using this protocol is helpful for patients with clinical levels of hostility.     

认知年老化和老年心理健康

认知功能和心理健康是健康老龄化的两个基本要素。认知功能随年老而加速减退,其机制的探讨表明,加工速度、工作记忆和执行功能在认知年老过程中均起重要的中介作用。大多数老年人的心理健康状况较好、生活满意度较高,其心态随年龄的增高而更趋于平静满足,但独居和绝对空巢老人的某些心理健康问题不容忽视。认知年老化过程和老年人的心理健康状况分别受诸多因素的影响,研究结果为延缓认知功能的年老减退和保持老年人的心理健康,以及实现健康老龄化和积极老龄化提供了有益的启示     

家庭暴力的社会认知心理机制及其防范策略的研究

家庭暴力已成为一个世界性的社会问题,然而我国学者对家庭暴力的研究多集中在现象的描述,原因的探讨和完善立法等方面,因而从社会心理学角度探究家庭暴力的认知机制对揭示家庭暴力的实质具有重要意义。心理学研究指出家庭暴力的产生及其对子女的影响而导致的暴力轮回都是认知结构上的偏差所导致,所以从改变认知结构入手的认知行为疗法将是防止家庭暴力的直接和有效的策略。     

Cognitive Appraisal as a Predictor of Cognitive Emotion Regulation Choice

More attention has recently been focused on how a person may choose their emotion regulation strategies depending on the situation. The present research examined how people cognitively appraised a situation that they had actually encountered in their life and how this appraisal affected their subsequent cognitive emotion regulation strategies. Three hundred and twenty‐four participants were instructed to recall the most stressful situation in the last month, and to rate how they cognitively appraised the situation (threat, centrality, controllability, commitment, injustice/unfairness, expectedness, expectancy) and how they cognitively regulated their emotion (self‐blame, blaming others, acceptance, refocus on planning, positive refocusing, rumination, positive reappraisal, putting into perspective, catastrophizing). Multiple regression analysis revealed that even after control for other variables, such as age, sex, personality, the time when the situation occurred and the intensity of negative emotion, all criteria of cognitive appraisal except for expectedness predicted cognitive emotion regulation choice. Implications and limitations of this research are discussed.     

时距估计年龄差异的认知机制

采用双任务的实验范式,通过对（5s、13s和26s）三个目标时距的产生法和复制法的结果来探讨时距估计年龄差异的认知机制。实验结果表明,在不同目标时距和不同的估计方法上均存在显著的年龄效应。年老被试在产生法上比年轻被试显著高估时距,存在非时间任务和年龄的交互作用,随着任务难度的增加年老被试会比年轻被试产生更长的时距。而在复制法上年老被试比年轻被试显著低估时距,但是只有在长时距条件下（26s）存在非时间任务和年龄的交互作用。本研究结果表明年老被试在产生法上对时距的高估可能与内部时钟减慢和注意资源减少有关,而在复制法上对时距的低估可能反映注意资源的减少。此外,对于长时距的时间复制,情节记忆的损伤也是导致时距估计年龄差异的一个可能原因。

The estimation of vehicle speed and stopping distance by pedestrians crossing streets in a naturalistic traffic environment

The ability to estimate vehicle speed and stopping distance accurately is important for pedestrians to make safe road crossing decisions. In this study, a field experiment in a naturalistic traffic environment was conducted to measure pedestrians’ estimation of vehicle speed and stopping distance when they are crossing streets. Forty-four participants (18–45 years old) reported their estimation on 1043 vehicles, and the corresponding actual vehicle speed and stopping distance were recorded. In the speed estimation task, pedestrians’ performances change in different actual speed levels and different weather conditions. In sunny conditions, pedestrians tended to underestimate actual vehicle speeds that were higher than 40 km/h but were able to accurately estimate speeds that were lower than 40 km/h. In rainy conditions, pedestrians tended to underestimate actual vehicle speeds that were higher than 45 km/h but were able to accurately estimate speeds ranging from 35 km/h to 45 km/h. In stopping distance estimation task, the accurate estimation interval ranged from 60 km/h to 65 km/h, and pedestrians generally underestimated the stopping distance when vehicles were travelling over 65 km/h. The results show that pedestrians have accurate estimation intervals that vary by weather conditions. When the speed of the oncoming vehicle exceeded the upper bound of the accurate interval, pedestrians were more likely to underestimate the vehicle speed, increasing their risk of incorrectly deciding to cross when it is not safe to do so.     

Failure to find a distance effect in pigeon choice: Manipulating amount and delay of reinforcement

The choice behavior of primates, including humans, displays a distance effect: Latency to choose between alternatives appears to increase with smaller differences in value. There is, so far, no demonstration of this effect in birds. Tests of distance effects in birds have been conducted in binary choice situations with a dominant alternative, where one alternative is superior to the other in all aspects that meaningfully contribute to value (e.g., provides access to the same reinforcer, but with a shorter delay). The present study considers the possibility that including dominant alternatives in choice tests precludes distance effects. Four pigeons were presented with binary choices between alternatives that varied in amount and delay. Some choices had a dominant alternative (smaller–sooner or larger–later vs. smaller–later) and some did not (smaller–sooner vs. larger–later). Across phases, only the delay to the smaller–sooner reinforcer varied. Distance effects were expected to be expressed as longer latencies as choice between smaller–sooner and larger–later reinforcers approached indifference. Despite the sensitivity of choice to differences in amount and delay, no distance effect was observed. Alternative explanations for the failure to find a distance effect in pigeon choice, including the Sequential Choice Model (SCM), are discussed.

A ratio scale for social distance

Choosing a larger–later reward over a smaller–sooner reward may be thought of as altruism toward one's future self. A question that arises in this connection is: What is the relation between delay and social discounting? To begin to answer this question, social and delay discount functions need to be comparable. Delay is ordinarily measured on a ratio scale (time), which allows for meaningful division and addition. Social distance is ordinarily measured on an ordinal scale (rank order of social closeness). To convert social distance to a ratio scale we use a psychophysical distance function obtained via magnitude estimation (Stevens, 1956). The distance functions obtained are well described by a power function (median exponent = 1.9); we show how they may be used to rescale ordinal to ratio social discount functions.     

跨期选择的认知机制与神经基础

跨期选择是指个体对发生在不同时间的成本与收益进行权衡的决策过程。跨期选择的计算模型从经济学的角度用数学模型来建构时间折扣函数,而认知成分模型则从心理学的角度来研究跨期选择中的心理效应与认知成分。跨期选择的神经基础有三种不同的研究取向：双机制加工取向、单机制加工取向、自我控制取向。未来研究应该在跨期选择的认知机制、神经通路及运行机制、跨期选择的应用,以及从进化的角度对人与动物的跨期选择行为进行更深入的研究。

Cognitive Therapy for Command Hallucinations: Not a Quasi-Neuroleptic

Command hallucinations (CH) are a distressing and high-risk group of symptoms that have long been recognised but little understood, with few effective treatments. In this paper we report and discuss the efficacy of cognitive therapy (CT) modified in accordance with ‘social rank theory,’ in a single blind randomised controlled trial. 38 patients with command hallucinations were randomly allocated to CT or treatment as usual and followed up for 6 then 12 months. Large reductions in compliance behaviour were obtained (effect size = 0.97) favouring the CT group. Other significant differences were found and maintained at 6 months follow up.     

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。     

Ignorance May Be Bliss, But Thought Suppression Promotes Superficial Cognitive Processing

This study examined the impact of thought suppression on the quality of cognitive processing and self-reported mood. While completing a stream-of-consciousness task about two topics sequentially, participants were either instructed to suppress negative thoughts or were given no suppression instructions. Computer-based content analyses indicated that thought suppression led to significantly less causal reasoning and discrepancy seeking. However, the suppression of negative thoughts also resulted in a more positive mood. Results suggest that thought suppression can improve mood but it comes with the cognitive cost of superficial processing.     

Everyday Cognitive Functioning in Cardiac Patients: Relationships Between Self-report,Report of a Significant Other and Cognitive Test Performance

ABSTRACT

Candidates for cardiac bypass surgery often experience cognitive decline. Such decline is likely to affect their everyday cognitive functioning. The aim of the present study was to compare cardiac patients' ratings of their everyday cognitive functioning against significant others' ratings and selected neuropsychological tests. Sixty-nine patients completed a battery of standardised cognitive tests. Patients and significant others also completed the Everyday Function Questionnaire independently of each other. Patient and significant other ratings of patients' everyday cognitive difficulties were found to be similar. Despite the similarities in ratings of difficulties, some everyday cognitive tasks were attributed to different processes. Patients' and significant others' ratings were most closely associated with the neuropsychological test of visual memory. Tests of the patients' verbal memory and fluency were only related to significant others' ratings. Test scores of attention and planning were largely unrelated to ratings by either patients or their significant others.     

大学生负面身体自我认知加工偏好

基于负面身体自我图式理论,采用词汇判断任务的实验范式,探讨负面身体自我者的认知加工偏好。研究1考察胖负面身体自我大学生对胖相关的身体信息词加工偏好,结果表明,加工胖身体相关词的编码速度比对照组显著更快,对胖消极和隐喻词偏好量大于积极词。研究2考察瘦负面身体自我大学生对瘦相关的身体信息词的加工偏好,发现对瘦相关词的编码速度显著比对照组更快,但对瘦积极词、消极词、隐喻词、形似词编码的偏好量不存在差异。结果支持负面身体自我图式指导认知加工
