Hand Switching Costs are not Uniform Across Response Components

We investigated the extent to which a complex finger sequence impacts on hand switching costs in a sequential action. Response component latencies (premotor, motor, and movement) were compared in no-switch (same finger performed the action of pressing and reaching) and switch conditions (pressing with one finger and completing the reaching action with the homologous finger from the other hand). Results showed that the switch condition presented longer latency for premotor and movement components. For the motor component, however, switch condition was faster. This expands the previous literature investigating switching costs using simple finger movements in more complex tasks. A mechanical explanation of the interplay between response subcomponents is provided to explain the inversion of response pattern for the motor component.     

Multimedia learning trumps retrieval practice in psychology teaching

It is well established that studying with (vs. without) visual illustrations as well as taking tests (vs. restudying) is beneficial for learning, but on which strategy should one put the efforts, or should they be combined for best learning? Eighty‐eight upper secondary school students were given a brief lecture presented verbally (6 classes) or with the aid of a visual illustration (visuoverbal, 6 classes). The information was processed again by taking a memory test or by restudying. Recall and transfer tests were conducted after some few minutes and again after one week. The visuoverbal lecture resulted in better learning than verbal presentation only. A significant study strategy by retention interval interaction was found. However, this interaction was not qualified by a testing effect. Hence, taking tests (retrieval practice) did not lead to better learning than restudying. It was concluded that it is worthwhile to use visual illustrations in teaching. However, the present study did not reveal any synergistic effects from the combination of visuoverbal presentation and retrieval practice.     

Identification and location tasks rely on different mental processes: a diffusion model account of validity effects in spatial cueing paradigms with emotional stimuli

Spatial cueing paradigms are popular tools to assess human attention to emotional stimuli, but different variants of these paradigms differ in what participants’ primary task is. In one variant, participants indicate the location of the target (location task), whereas in the other they indicate the shape of the target (identification task). In the present paper we test the idea that although these two variants produce seemingly comparable cue validity effects on response times, they rest on different underlying processes. Across four studies (total N?=?397; two in the supplement) using both variants and manipulating the motivational relevance of cue content, diffusion model analyses revealed that cue validity effects in location tasks are primarily driven by response biases, whereas the same effect rests on delay due to attention to the cue in identification tasks. Based on this, we predict and empirically support that a symmetrical distribution of valid and invalid cues would reduce cue validity effects in location tasks to a greater extent than in identification tasks. Across all variants of the task, we fail to replicate the effect of greater cue validity effects for arousing (vs. neutral) stimuli. We discuss the implications of these findings for best practice in spatial cueing research.     

社会知觉视角下道德诉求方式如何提升劝捐效果

如何有效地引导个体“慷慨解囊”一直是理论和实践都关注的热点。基于道德基础理论和刻板印象内容模型, 研究考察了在不同社会知觉(温暖型vs.能力型)的劝捐主体中, 两种道德诉求方式(个体人道诉求vs.群体规范诉求)对劝捐效果的影响及其内在机制。3个实验的结果显示：温暖型(能力型)劝捐主体与个体人道诉求(群体规范诉求)更为契合, 更有利于提升劝捐效果; 温暖型劝捐主体进行个体人道诉求主要通过唤起个体的自我效能而提升劝捐效果, 而能力型劝捐主体进行群体规范诉求则主要通过增强个体的反应效能而提升劝捐效果。     

Practice variability promotes an external focus of attention and enhances motor skill learning

Variability in practice has been shown to enhance motor skill learning. Benefits of practice variability have been attributed to motor schema formation (variable versus constant practice), or more effortful information processing (random versus blocked practice). We hypothesized that, among other mechanisms, greater practice variability might promote an external focus of attention on the intended movement effect, while less variability would be more conducive to a less effective internal focus on body movements. In Experiment 1, the learning of a throwing task was enhanced by variable versus constant practice, and variable group participants reported focusing more on the distance to the target (external focus), while constant group participants focused more on their posture (internal focus). In Experiment 2, golf putting was learned more effectively with a random compared with a blocked practice schedule. Furthermore, random group learners reported using a more effective distal external focus (i.e., distance to the target) to a greater extent, whereas blocked group participants used a less effective proximal focus (i.e., putter) more often. While attentional focus was assessed through questionnaires in the first two experiments, learners in Experiment 3 were asked to report their current attentional focus at any time during practice. Again, the learning of a throwing task was more effective after random relative to blocked practice. Also, random practice learners reported using more external focus cues, while in blocked practice participants used more internal focus cues. The findings suggest that the attentional foci induced by different practice schedules might be at least partially responsible for the learning differences.     

Judging credibility: Can spaced lessons help students think more critically online?

Despite the prevalence of the spacing effect in the psychological literature, the impact of lesson timing has not yet been fully explored in real classrooms. The current study examined whether spacing could improve long‐term retention of both factual and critical thinking curriculum‐based teaching materials for children. Students 9 to 12 years old were taught to judge the credibility of websites in either three consecutive days of lessons or one lesson per week. Thirty‐five days after the final lesson, students were tested on factual knowledge and applied their knowledge to evaluating a new website. Students in the spaced condition remembered more facts from the lessons and were better able to explain their website ratings than students in the massed group.     

Situationism and Moral Responsibility

In section 1, I will describe how moral responsibility requires normative competence. In section 2, I will introduce an influential social psychology experiment and consider one of its philosophical interpretations, situationism. In section 3, I will discuss the possession response in defense of normative competence. This is an approach to save normative competence via possession, and in turn the concept of the morally responsible agent, by relinquishing the need for exercising normative competence. After discussing its pros and cons, section 4 will focus on the exercise response, which emphasizes each singular exercise of normative competence. Given these two responses, I will argue that we are faced with a dilemma. If we admit that the concept of the morally responsible agent is grounded in the mere possession of normative competence, then the concept becomes useless in a practical sense, forcing us to embrace a concept that is tied to the exercise of normative competence. If we admit that the morally responsible agent is grounded in only the exercise of normative competence, the concept of the morally responsible agent no longer aligns with common sense.     

霍妮的自我理论及其当代响应

霍妮以真实自我的理论预设为起点,通过对真实自我健康成长过程的自我实现模式的分析,完成了真实自我实在性的论证。真实自我有机地连贯了霍妮对自我异化的分析和对自我实现的探讨,构成了霍妮自我理论的核心基础。霍妮的真实自我思想,由于抛弃了传统精神分析的人性观,历史性地获得了当代心理学家的积极响应。     

视觉运动Simon效应和认知Simon效应的影响因素及机制

Simon效应是指与反应要求无关的刺激位置和反应位置在同侧时, 个体反应更快更准确的现象。对于Simon效应的产生机制, 大多数研究者认为, 在不同实验情境中获得的Simon效应有共同的产生机制。但是, 越来越多的证据显示, 在刺激形式、排列方式、刺激—反应规则以及反应方式等因素的影响下, 存在两种不同性质的Simon效应, 即视觉运动Simon效应和认知Simon效应。视觉运动Simon效应源于刺激位置自动激活其同侧反应所产生的影响, 认知Simon效应源于转译生成的编码间的相互干扰, 两者分别与背侧通路和腹侧通路的加工有关。     

延迟命名任务中图词干扰效应的眼动研究

采用图-词分离呈现及眼动技术探讨在延时命名条件下图-词干扰效应发生的位置。结果发现：（1）延时命名图片时,仍出现图-词干扰效应和频率效应;（2）与命名干扰词相比,命名图片时图片的回视率高,注视时间长;（3）图片的注视时间也出现频率效应和图-词干扰效应。这说明即使在延时命名图片的条件下,目标词汇仍需要再次激活,频率效应和图-词干扰效应是发生在词汇化过程中,反驳反应排除理论的图-词干扰反应选择阶段的观点,支持了词汇化选择竞争的理论。
