  studied in detail. We have found that the selectivity can be controlled by the acidity of the catalyst and by the temperature, being able to obtain selectively either the cycloheptatriene carbaldehyde product, arising from a single ring-contraction event, or phenylacetaldehyde that is formed after a second ring contraction process. A complete mechanistic picture of the reaction and a rationale behind the

  环辛四烯氧化物在温和条件下使用 Brønsted 酸催化进行两个连续环收缩事件的能力已得到详细研究。我们发现选择性可以通过催化剂的酸度和温度来控制，能够选择性地获得由单一环收缩事件产生的环庚三烯甲醛产物，或在第二次环收缩后形成的苯乙醛过程。基于实验和计算数据，提供了反应的完整机理图和催化剂影响背后的基本原理。最后，这种酸催化的环收缩与原位对映选择性烯丙基化反应，在手性磷酸催化剂存在下进行时，会产生富含对映体的环庚三烯基取代的高烯丙醇。通过铜催化的亲核硼化/环化方案，这些同型烯丙基醇也被转化为富含对映体的氧杂硼烷。

• Interaction of knowledge-driven and data-driven processing in category learning
  作者：Andre Vandierendonck、Yves Rosseel

  The present paper argues that category learning is both a data-driven and a knowledge-driven process. This is described in a generic model that distinguishes between categorical knowledge, conceptual knowledge, and implicit cognitive theories. The model assumes that each of these knowledge aspects may affect the process of category learning by affecting the way similarities between objects are perceived. This central assumption of the model is tested in two experiments. The first experiment shows that the presence or absence of prior categorical acid conceptual knowledge affects the psychological stimulus space by changing the saliency of the stimulus dimensions. The second experiment uses these weights to predict the distribution of errors over the stimuli and the number of trials to criterion in category learning by other participants under the same knowledge conditions. We conclude that prior categorical and conceptual knowledge affect category learning by mediation of similarity perception, and discuss the implications of these results.
