Child and adolescent psychotherapy outcomes in experiments versus clinics: Why the disparity?

In a recent article, Weisz, Weiss, and Donenberg (1992) compared the effects of child and adolescent psychotherapy in experimental studies and in studies of clinic practice. Here we update that report with new information and we explore 10 possible reasons why, to date, therapy in experiments appears to have shown larger effect sizes than therapy in clinics. We find that beneficial therapy effects are associated with three factors which are more common in research therapy than in clinic therapy: (a) the use of behavioral (including cognitive-behavioral) methods, (b) reliance on specific, focused therapy methods rather than mixed and eclectic approaches, and (c) provision of structure (e.g., through treatment manuals) and monitoring (e.g., through review of therapy tapes) to foster adherence to treatment plans. These three factors all involve dimensions along which clinic procedures could be altered.     

记叙文时间转换机制

采用实时窗口阅读技术和再认探测技术,探讨了间断性时间短语与场景跨度的关系对时间转换的影响,对Zwaan提出的强印象假设与Anderson提出的场景模型进行检验。实验1探讨在与Zwaan实验材料相似长度的场景中人们是否会忽略对较短的非连续性时间标记的处理;实验2探讨在时间跨度较大的场景中,与Zwaan实验材料相似长度的间断性时间标记是否会引起时间的转换。结果表明时间信息的间断性只是产生时间转换的必要条件之一,而不是充分条件;读者在处理间断性的时间短语进行时间转换时还会参照时间短语的跨度与场景跨度的比例。     

声旁规则性对命名声旁和整字的影响

探讨声旁规则性对命名声旁或整字的影响,在速示与慢示呈现条件下命名声旁或汉字。结果发现：（1）声旁命名在速示呈现时因规则声旁易化;慢示呈现时无显著规则性效应,但受声旁部件数影响;（2）在两种呈现条件下,命名含不表音声旁字的反应时最快,错误率最低;命名含单部件、高频声旁字的反应时慢,错误率高;命名含多部件、低频声旁字的反应时快,错误率低。说明是声旁规则性对声旁命名有易化作用;对整字命名有干扰作用,但与声旁频率与部件数有关。

Search efficiency is not sufficient: The nature of search modulates stimulus-driven attention

It has long been debated whether or not a salient stimulus automatically attracts people’s attention in visual search. Recent findings showed that a salient stimulus is likely to capture attention especially when the search process was inefficient due to high levels of competition between the target and distractors. Expanding these studies, the present study proposes that a specific nature of visual search, as well as search efficiency, determines whether or not a salient, task-irrelevant singleton stimulus captures attention. To test this proposition, we conducted three experiments, in which participants performed two visual search tasks whose underlying mechanisms are known to be different: orientation-feature search and Landolt-C search tasks. We found that color singleton distractors captured attention when participants performed the orientation-feature search task. The magnitude of this capture effect increased as search efficiency decreased. On the contrary, the capture by singleton distractors was not observed under the Landolt-C search task. This differential pattern of capture effect was not due to differences in search efficiency across the search tasks; even when search efficiency was controlled for, stimulus-driven capture of attention by a salient distractor was found only under the feature search. Based on these results, the present study suggests that in addition to search efficiency, the nature of search strategy and the extent to which attentional control is strained play crucial roles in observing stimulus-driven attentional capture in visual search.     

汉字词在不同方位与不同排列组合条件下对念读速度与准确性的影响

本研究探讨了汉字词在不同方位与不同排列组合条件下对念读速度与准确性的影响.实验结果表明逆意排列的汉字词处于不同方位(正位、左右倾斜90°、倒位),对汉字词的念读速度产生明显影响.汉字词处于正位时,念读速度最快;其次是处于左斜与右斜90°;对汉字词的念读速度最慢而准确性最低是处于倒位时(汉字词颠倒).汉字词无论是顺意排列或是逆意排列,正位结果均明显优于倒位结果;但汉字词在倒位顺意排列条件下,结果优于正位逆意排列的结果,这表明,字词间的意义联系的作用大于字词方位的作用.     

Neural correlates of comprehension and production of nouns and verbs in Chinese

This paper reports a conjunction analysis between semantic relatedness judgment and semantic associate generation of Chinese nouns and verbs with concrete or abstract meanings. The results revealed a verb-specific task-independent region in LpSTG&MTG, and task-dependent activation in a left frontal region in semantic judgment and the left SMG in semantic associate production. The observation of word class effects converged on Yu, Law, Han, Zhu, and Bi (2011), but contrasted with null findings in previous reports using a lexical decision task. While word class effects in the left posterior temporal cortices have been described in previous studies of languages with rich inflectional morphology, the significance of this study lies in its demonstration of the effects in these regions in a language known to have little inflectional morphology. In other words, differential neural responses to nouns and verbs can be observed without confounding from morphosyntactic operations or contrasts between actions and objects.
