IAT效应在不同目标概念水平上的差异研究

采用IAT实验设计,考察大学生对不同概念词的内隐态度之间的差别。结果发现,八组实验材料都产生了显著的IAT效应;不同性别的测验材料的IAT效应间不存在显著差异,不同喜好程度的测验材料的IAT效应间存在显著差异,且两个因素存在显著的交互作用。研究表明,IAT效应既可在上位概念水平上产生,亦可在下位概念水平上产生。     

Planning ahead: college seniors’ concerns about career-marriage conflict

Career-marriage conflict (CMC) reflects the reality that for many college seniors, the next decade of their lives will be spent launching a career, often a very demanding one, building a long-term romantic relationship, and coordinating the demands of two careers. We focus on the antecedents and correlates of these concerns. Based on social-role theory, we hypothesized that seniors whose mothers worked outside the home while the seniors were children would express less concern about CMC than seniors with at-home mothers. We also hypothesized that seniors’ expectations about the timing of their marriages and childbearing relate to their concerns about CMC, with students who plan to delay family formation having fewer CMC concerns. These hypotheses were supported through an analysis of secondary data from a sample of 324 college seniors at a private university in the Northeast.     

社会认知中印象形成的启动效应研究:频因,近因效应

本文以社会认知为出发点,考察印象形成的启动效应,它采用性质不同的成语作为实验材料,并操纵启动刺激的结构,系统探讨了印象形成的启动效应中原因与近因效应,结果发现：当呈现表示同一品质但性质相反的成语时,如果启动刺激和目标刺激之间不延迟,则近因在启动效应中起作用,但在延迟情况下,频因在启动效应中占优势;同时随着延迟的出现,启动效应明显变小。实验结果支持启动效应的突触模式说;     

Health behaviour change theory meets falls prevention: Feasibility of a habit-based balance and strength exercise intervention for older adults

ObjectivesHabit formation is a proposed mechanism for behaviour maintenance. Very few falls prevention studies have adopted this as an intervention framework and outcome. Therefore, we tested feasibility of a theory-based behaviour change intervention that encouraged women to embed balance and strength exercises into daily life routines (e.g., eating, self-care routines).DesignThe EASY LiFE study was a mixed-methods, 4-month feasibility intervention that included seven group-based sessions and two telephone calls.Main outcome measuresWe obtained performance-based (i.e., Short-Physical-Performance-Battery) and psychological self-report measures (i.e., intention, self-efficacy, planning, action control, habit strength, quality of life) from 13 women at baseline (T1) and 4-month follow-up (T2). We applied the Framework-Method to post-intervention, semi-structured interviews to evaluate program content and delivery.ResultsIn total, 10 of 13 women completed the program (M_age = 66.23, SD = 3.98) and showed changes in their level of action control [mean difference_T1−T2 = 1.7, 95% CI (−2.2 to −0.8)], action planning [mean difference_T1−T2 = 0.8, 95% CI (−1.1 to −0.2)], automaticity [mean difference_T1−T2 = 2.5, 95% CI (−3.7 to −1.2)], and exercise identity [mean difference_T1−T2 = 2.0, 95% CI (−3.2 to −0.8)]. Based on the Theoretical Domains Framework we identified knowledge, behavioural regulation, and social factors as important themes. For program delivery, dominant themes were engagement, session facilitators and group format.ConclusionThe theory-based framework showed feasibility for promoting lifestyle integrated balance and strength exercise habits. Using activity and object-based cues may be particularly effective in generating action and automaticity.     

Understanding and disagreement in belief ascription

It seems uncontroversial that Dalton wrongly believed that atoms are indivisible. However, the correct analysis of Dalton’s belief and the way it relates to contemporary beliefs about atoms is, on closer inspection, far from straightforward. In this paper, I introduce four features that any candidate analysis is plausibly bound to respect. I argue that theories that individuate concepts at the level of understanding are doomed to fail in this endeavor. I formally sketch an alternative and suggest that cases such as the one presented provide support for the claim that the genuine source for concept individuation is public sharable thought.     

Stimulus–response correspondence effect as a function of temporal overlap between relevant and irrelevant information processing

The stimulus–response correspondence (SRC) effect refers to advantages in performance when stimulus and response correspond in dimensions or features, even if the common features are irrelevant to the task. Previous research indicated that the SRC effect depends on the temporal course of stimulus information processing. The current study investigated how the temporal overlap between relevant and irrelevant stimulus processing influences the SRC effect. In this experiment, the irrelevant stimulus (a previously associated tone) preceded the relevant stimulus (a coloured rectangle). The irrelevant and relevant stimuli onset asynchrony was varied to manipulate the temporal overlap between the irrelevant and relevant stimuli processing. Results indicated that the SRC effect size varied as a quadratic function of the temporal overlap between the relevant stimulus and irrelevant stimulus. This finding extends previous experimental observations that the SRC effect size varies in an increasing or decreasing function with reaction time. The current study demonstrated a quadratic function between effect size and the temporal overlap.     

Discerning the Spirits, Practicing the Faiths: Why Be Lutheran?

Some spiritual wanderers today are "unstuck" in their faith, therefore, they have many faiths; while others are securely "stuck" in their tradition. Getting stuck is desirable, and the path is through spiritual practice. One's inner life and even perception of reality become transformed through daily habits such as prayer, worship, and discipline. The Lutheran insight that a practicing Christian is simultaneously saint and sinner offers comfort and honest self–understanding.

数学等值概念获得的过渡性学习者认知发展的实验研究

就数学等值概念获得而言,一般地,过渡性学习者在解决简单问题作业时趋向于使用一种正确策略,而当题目较难时则使用几种不同的错误策略。经过针对性的指导（或输入适当信息）后极易掌握此概念,表现为使用一种正确且充分的策略。同时,“言语一手势失匹配”可能不是过渡性学习者的必然的认知特征。
