推理与决策的双加工理论研究简评

决策与推理的双加工理论是一个颇有影响力的理论,通过对两个加工系统的基本特点、区别点以及基本关系、推理错误原因等几个方面进行分析阐述,发现目前在该理论的一些基本问题的认识上还存在诸多问题。主要表现在以下几方面：（1）两个加工系统的关键区别点不在于工作记忆有无绝对参与;（2）对于推理和决策错误的原因,不同的双加工理论给出了不一致的解释;（3）今后有待从情绪与推理决策的关系、影响等方面加深对推理与决策错误的理解     

Memory for words location in writing

In two experiments, we investigated memory for words location after writing a text. Experiment 1 demonstrated the existence of a memory for words location in writing by showing that participants who first composed a text and were then asked to locate words extracted from their text performed above a chance level established using a computer simulation, and better than participants who did not compose a text but were told the subject of the text. Experiment 2 showed that memory for words location in writing is mainly supported by a visuospatial representation of the text, as indicated by the lower recall of words location by participants who performed a visuospatial concurrent task at the time of the composition, compared with participants who performed a verbal concurrent task. The findings highlight the role of a spatial representation of the physical layout of the text and the role of such a memory in the writing process.

Coping with examinations: Exploring relationships between students' coping strategies,implicit theories of ability,and perceived control

Background Relatively little is known about the contribution of students' beliefs regarding the nature of academic ability (i.e. their implicit theories) on strategies used to deal with examinations. Aims This study applied Dweck's socio‐cognitive model of achievement motivation to better understand how students cope with examinations. It was expected that students' implicit theories of academic ability would be related to their use of particular coping strategies to deal with exam‐related stress. Additionally, it was predicted that perceived control over exams acts as a mediator between implicit theories of ability and coping. Sample Four hundred and ten undergraduate students (263 males, 147 females), aged from 17 to 26 years old (M = 19.73, SD = 1.46) were volunteers for the present study. Methods Students completed measures of coping, implicit theories of academic ability, and perception of control over academic examinations during regular classes in the first term of the university year. Results Multiple regression analyses revealed that incremental beliefs of ability significantly and positively predicted active coping, planning, venting of emotions, seeking social support for emotional and instrumental reasons, whereas entity beliefs positively predicted behavioural disengagement and negatively predicted active coping and acceptance. In addition, analyses revealed that entity beliefs of ability were related to coping strategies through students' perception of control over academic examinations. Conclusions These results confirm that exam‐related coping varies as a function of students' beliefs about the nature of academic ability and their perceptions of control when approaching examinations.     

Psychological profiles and emotional regulation characteristics of women engaged in risk-taking sports

We investigated the psychological profiles and emotional regulation characteristics of women involved in risk-taking sports. The research sample (N=180) consisted of three groups of women engaged in: (1) non-risk sports (N=90); (2) risk-taking sports for leisure purposes (N=53); or (3) risk-taking sports as professionals (N=37). Each participant completed five questionnaires, the Sensation Seeking Scale, the Bem Sex Role Inventory, the Barratt Impulsiveness Scale, Risk & Excitement Inventory, and the Toronto Alexithymia Scale. The results revealed significant differences between the groups' profiles. Of particular interest are the differences that exist between the profiles of Group 2 (escape profile, masculine gender identity, and high scores on sensation seeking, impulsivity, alexithymia) and Group 3 (compensation profile, androgynous gender identity, average score on sensation seeking, and low scores on impulsivity, alexithymia). We propose that the professional woman might be considered a model for preventing destructive risk-taking behaviors.     

消极的与积极的:谎言的区分及其道德意义 ——兼论如何理解康德的谎言禁令

康德谎言禁令认为任何时候都必须诚实,甚至在面对凶犯询问朋友藏身之处时也不能说假话,这引发了激烈争议。谎言的道德价值与说谎者的情境地位有本质关联:主动的、以骗取信任来获取利益的谎言是积极谎言,是谎言禁令所严格禁止的;被动的、避免伤害的谎言是消极谎言。消极谎言可以分为面对灾祸的与面对邪恶的两种情境。面对灾祸的谎言是善意谎言,出自避免伤害的动机;面对邪恶的被迫谎言不属于“蓄意的不真实”,而是严格意义的“被迫的不真实”;这不是为谎言辩护,而是为处于邪恶的逼迫之情境中弱者或受害者的生存权辩护。上述概念与真实的背离,是康德谎言禁令产生道德困惑与理论争议的根本原因。     

Goldman On Knowledge As True Belief

Alvin Goldman contends that, in addition to the familiar sense or use of the term “knowledge” according to which knowledge is at least true justified belief, there is a weaker yet strict sense or use of the term “knowledge” according to which knowledge amounts to nothing more than information-possession or mere true belief. In this paper, I argue that Goldman has failed to show that there is such a weaker sense, and that, even if he had shown this, he has not shown that this putative weaker sense is a strict one by his own criterion for strictness.     

Biased extensive measurement: The homogeneous case

In the homogeneous case of one type of objects, we prove the existence of an additive scale unique up to a positive scaling transformation without transitivity of indifference and with a property of homothetic invariance weaker than monotonicity. The representation, which is a particular case of a semiorder representation, reveals a unique positive factor α?1 that biases extensive structures and explains departures from these standard axioms of extensive measurement (α=1). We interpret α as characterizing the qualitative influence of the underlying measurement process and we show that it induces a proportional indifference threshold.     

Miss it and miss out: Counterproductive nonspatial attentional capture by task-irrelevant,value-related stimuli

Recent studies of visual search suggest that learning about valued outcomes (rewards and punishments) influences the likelihood that distractors will capture spatial attention and slow search for a target, even when those value-related distractors have never themselves been the targets of search. In the present study, we demonstrated a related effect in the context of temporal, rather than spatial, selection. Participants were presented with a temporal stream of pictures in a fixed central location and had to identify the orientation of a rotated target picture. Response accuracy was reduced if the rotated target was preceded by a “valued” distractor picture that signaled that a correct response to the target would be rewarded (and an incorrect response punished), relative to a distractor picture that did not signal reward or punishment. This effect of signal value on response accuracy was short-lived, being most prominent with a short lag between distractor and target. Impairment caused by a valued distractor was observed if participants were explicitly instructed regarding its relation to reward/punishment (Exps. 1, 3, and 4), or if they could learn this relationship only via trial-by-trial experience (Exp. 2). These findings show that the influence of signal value on attentional capture extends to temporal selection, and also demonstrate that value-related distractors can interfere with the conscious perception of subsequent target information.     

Inducing an availability heuristic on the Wason selection task overrides the matching bias

A long history of examining reasoning using the Wason selection task has revealed that many respondents are biased towards choices that match the items expressed in the rule. One reason for this particular heuristic may be that no better information is immediately available, and thus matching items win over the competing choice simply via recognition. In two experiments, we sought to examine whether a stronger memory trace could override the matching bias. We created rules from common, easily recognisable nursery rhymes and varied the degree to which the presented rules matched the commonly known rhymes. The components of the remembered rhyme had a strong influence on the participants’ selections, suggesting that a strong memory trace can override the usual matching bias. We provide an interpretation of these results in light of answer fluency, mental models, and probabilistic estimates.     

面孔再认及学习程度判断中的同龄效应

同龄效应指个体对自己年龄段面孔的记忆成绩显著高于其他年龄面孔.实验采用3×3混合设计,考察不同年龄被试对面孔再认及学习程度判断中的同龄效应,探讨同龄效应的发展规律.结果显示,青年和老年人对同龄面孔的再认显著好于异龄面孔,儿童对同龄与异龄面孔的再认成绩差异不显著;各组被试对不同年龄的面孔学习程度判断准确性之间的差异没有区别.这表明:青年和老年人在面孔再认中出现了同龄效应,儿童没有表现出同龄效应;个体学习程度判断中不存在同龄效应,且这种特点与年龄无关.
