The testing effect and analogical problem-solving

Researchers generally agree that retrieval practice of previously learned material facilitates subsequent recall of same material, a phenomenon known as the testing effect. There is debate, however, about when such benefits transfer to related (though not identical) material. The current study examines the phenomenon of transfer in the domain of analogical problem-solving. In Experiments 1 and 2, learners were presented a source text describing a problem and solution to read which was subsequently either restudied or recalled. Following a short (Experiment 1) or long (Experiment 2) delay, learners were given a new target text and asked to solve a problem. The two texts shared a common structure such that the provided solution for the source text could be applied to solve the problem in the target text. In a combined analysis of both experiments, learners in the retrieval practice condition were more successful at solving the problem than those in the restudy condition. Experiment 3 explored the degree to which retrieval practice promotes cued versus spontaneous transfer by manipulating whether participants were provided with an explicit hint that the source and target texts were related. Results revealed no effect of retrieval practice.     

The Effect of Transparency on Framing Effects in Within‐Subject Designs

A long‐lasting assumption about the framing effect is that if the participants discover the purpose of the experiment in a within‐subject design, then this test transparency would trigger them to override their initial answer and make coherent choices. For this reason, researchers try to mask the connection between the two parts of the test by inserting filling questions or a time delay between the two parts of the test. In this research, we explored the extent to which these customarily used masking solutions are effective in increasing test sensitivity for the framing effect. In three experiments, we assessed the effect of masking on the tests of the attribute framing and the risky‐choice framing effects. Contradicting the general belief, our results indicate that these effects are already measurable without any masking or delay and we found no convincing evidence that the attempts to decrease task transparency provide worthwhile benefits for general tests of the effect. Beyond their practical relevance, the results question whether the test is a good measure of coherence rationality and better suit those accounts that suggest that the two parts of the framing tasks cannot be regarded as identical.

The Flushtration Count Illusion: Attribute substitution tricks our interpretation of a simple visual event sequence

When faced with a difficult question, people sometimes work out an answer to a related, easier question without realizing that a substitution has taken place (e.g., Kahneman, 2011, Thinking, fast and slow. New York, Farrar, Strauss, Giroux). In two experiments, we investigated whether this attribute substitution effect can also affect the interpretation of a simple visual event sequence. We used a magic trick called the ‘Flushtration Count Illusion’, which involves a technique used by magicians to give the illusion of having seen multiple cards with identical backs, when in fact only the back of one card (the bottom card) is repeatedly shown. In Experiment 1, we demonstrated that most participants are susceptible to the illusion, even if they have the visual and analytical reasoning capacity to correctly process the sequence. In Experiment 2, we demonstrated that participants construct a biased and simplified representation of the Flushtration Count by substituting some attributes of the event sequence. We discussed of the psychological processes underlying this attribute substitution effect.     

The role of the head in configural body processing: Behavioural and electrophysiological evidence from the inversion and scrambling effect

The present study aimed to further explore the role of the head for configural body processing by comparing complete bodies with headless bodies and faceless heads (Experiment 1). A second aim was to further explore the role of the eye region in configural face processing (Experiment 2). Due to that, we conducted a second experiment with complete faces, eyeless faces, and eyes. In addition, we used two effects to manipulate configural processing: the effect of stimulus inversion and scrambling. The current data clearly show an inversion effect for intact bodies presented with head and faces including the eye region. Thus, the head and the eye region seem to be central for configural processes that are manipulated by the effect of stimulus inversion. Furthermore, the behavioural and electrophysiological body inversion effect depends on the intact configuration of bodies and is associated with the N170 as the face inversion effect depends on the intact face configuration. Hence, configural body processing depends not only on the presence of the head but rather on a complete representation of human bodies that includes the body and the head. Furthermore, configural face processing relies on intact and complete face representations that include faces and eyes.     

数字空间表征的在线建构：来自干扰情境中数字SNARC效应的证据

尽管已有研究发现数字以空间方式表征在人类记忆系统, 但是人脑如何完成数字的空间表征尚存争议。本研究两个实验在不同比例的数字字母(实验1)和不同比例的数字汉字(实验2)混合情境中考察了数字空间表征特点及其机制, 对上述争议进行了深入研究。结果发现：(1)当数字字母比例为“1 : 1”时, 数字加工中不出现SNARC效应。当数字字母比例为“1 : 6”和“6 : 1”时, 数字加工中均出现SNARC效应。即数字字母比例与数字SNARC效应之间呈倒“U”型关系。(2)数字汉字混合情境中数字汉字比例与数字SNARC效应之间同样呈倒“U”型关系。结果说明：(1)干扰刺激与数字混合呈现会影响数字SNARC效应。(2)干扰刺激加工对数字SNARC效应的影响受到数字与干扰刺激比例的调节, 且具有跨干扰材料的稳定性。研究结果意味着数字的空间表征是人类通过统计学习在线建构的, 支持了工作记忆理论。     

中文词类信息在副中央凹中的加工

本研究采用边界范式, 通过操纵预视词和目标词的词类一致性探讨中文阅读中副中央凹中能否加工词类信息。实验采用单因素3水平设计, 三种预视条件: 一致预视、词类不违背预视、词类违背预视。对实验数据进行线性混合模型及贝叶斯分析发现: 词类违背条件和词类不违背条件下对目标词的注视时间和注视概率没有显著差异, 即无词类信息的预视效应。该结果倾向于支持序列注意转移模型, 眼动控制模型的未来发展应更加关注灵活性和普适性。     

青少年友谊网络与受欺凌的共同变化关系：一项纵向社会网络分析研究

欺凌是一种涉及多类行为和多主体互动的群体过程, 但是已有研究很少在同伴的群体互动和关系变化过程中研究欺凌相关行为的发展。尤其是受欺凌作为一种被动承受而非主动选择的行为结果, 对其在同伴情境中的变化过程研究更为有限。本研究从青少年的友谊网络与其受欺凌的共变关系入手, 采用纵向社会网络分析法, 对来自26个班1406名学生进行为期1年的3个时间点(七年级末、八年级上学期末、八年级下学期末)的追踪研究, 结果发现：(1)受欺凌影响群体内友谊关系的建立：受欺凌水平高的青少年更难以与同伴建立朋友关系(同伴回避效应), 且更倾向于选择同样受欺凌水平高的个体作为朋友(同伴选择效应); (2)友谊关系影响受欺凌水平的变化：在群体中拥有更多朋友关系的青少年, 其受欺凌水平会逐渐降低(同伴保护效应); 但另一方面, 拥有高受欺凌水平朋友的青少年, 自己的受欺凌水平会随着时间呈增高趋势(同伴影响效应); (3)随着时间的发展, 女生的受欺凌水平比男生更容易降低(性别影响效应)。研究结果揭示了友谊网络和受欺凌的共变关系, 为校园欺凌群体干预提供启示。
