Evidence for Implicit Learning in Syntactic Comprehension

This study provides evidence for implicit learning in syntactic comprehension. By reanalyzing data from a syntactic priming experiment (Thothathiri & Snedeker, 2008), we find that the error signal associated with a syntactic prime influences comprehenders' subsequent syntactic expectations. This follows directly from error‐based implicit learning accounts of syntactic priming, but it is unexpected under accounts that consider syntactic priming a consequence of temporary increases in base‐level activation. More generally, the results raise questions about the principles underlying the maintenance of implicit statistical knowledge relevant to language processing, and about possible functional motivations for syntactic priming.     

外化行为问题与集体道德情绪、集体责任行为之关系：班级氛围的调节效应*

采用调查法,随机选取上海市3所普通中小学四、六、八、十年级的755名学生为被试,探讨班级氛围在外化行为问题与集体道德情绪、集体责任行为关系间的调节作用。结果表明：(1)男生的外化行为问题显著高于女生,其感知的班级氛围显著低于女生。而男、女生集体道德情绪与集体责任行为的性别差异不显著;(2)学生感知的班级氛围随年龄的增长先下降再上升,八年级时最低;集体道德情绪和集体责任行为随着年级的增高而呈下降趋势,小学生(四、六年级)的集体道德情绪和集体责任行为得分均比中学生(八、十年级)高,高一(十年级)学生的得分处于最低水平;(3)外化行为问题与集体道德情绪、集体责任行为的关系受班级氛围的调节。与消极的班级氛围相比,积极的班级氛围能够弱化外化行为问题与集体道德情绪、集体责任行为的负向关联。结果揭示了积极的班级氛围对外化行为问题学生具有一定的保护作用,有助于改善这些学生的社会适应能力。     

Exploring the determinants of dual goal facilitation in a rule discovery task

Wason's standard 2-4-6 task requires discovery of a single rule and leads to around 20% solutions, whereas the dual goal (DG) version requires discovery of two rules and elevates solutions to over 60%. We report an experiment that aimed to discriminate between competing accounts of DG facilitation by manipulating the degree of complementarity between the to-be-discovered rules. Results indicated that perfect rule complementarity is not essential for task success, thereby undermining a key tenet of the goal complementarity account of DG facilitation. The triple heterogeneity account received a good degree of support since more varied triple exploration was associated with facilitatory DG conditions, in line with this account's prediction that task success is associated with the creative search of the problem space. The contrast class account (an extension of Oaksford & Chater's, 1994, iterative counterfactual model) was also corroborated in that the generation of descending triples was demonstrated to be the dominant predictor of DG success. We focus our discussion on conceptual ideas relating to the way in which iterative counterfactual testing and contrast class identification may work together to provide a powerful basis for effective hypothesis testing.     

The word class effect in the picture–word interference paradigm

The word class effect in the picture–word interference paradigm is a highly influential finding that has provided some of the most compelling support for word class constraints on lexical selection. However, methodological concerns called for a replication of the most convincing of those effects. Experiment 1 was a direct replication of Pechmann and Zerbst (2002 Pechmann, T. and Zerbst, D. 2002. The activation of word class information during speech production. Journal of Experimental Psychology: Learning, Memory, and Cognition, 28: 233–243. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]; Experiment 4). Participants named pictures of objects in the context of noun and adverb distractors. Naming took place in bare noun and sentence frame contexts. A word class effect emerged in both bare noun and sentence frame naming conditions, suggesting a semantic origin of the effect. In Experiment 2, participants named objects in the context of noun and verb distractors whose word class relationship to the target and imageability were orthogonally manipulated. As before, naming took place in bare noun and sentence frame naming contexts. In both naming contexts, distractor imageability but not word class affected picture naming latencies. These findings confirm the sensitivity of the picture–word interference paradigm to distractor imageability and suggest the paradigm is not sensitive to distractor word class. The results undermine the use of the word class effect in the picture–word interference paradigm as supportive of word class constraints during lexical selection.     

Processing temporary syntactic ambiguity: The effect of contextual bias

This paper reports two experiments using sentences with a temporary ambiguity between a direct object and a sentence complement analysis that is resolved toward the normally preferred direct object analysis. Postverbal noun phrases in these sentences could be ambiguously attached as either a direct object or the subject of a sentence complement, whereas in unambiguous versions of the sentences the subcategorization of the verb forced the direct object interpretation. Participants read these sentences in relatively long paragraph contexts, where the context supported the direct object analysis (“preferred”), supported the sentence complement analysis (“unpreferred”), or provided conflicting evidence about both analyses (“conflicting”). Self-paced reading times for ambiguous postverbal noun phrases were almost equivalent to the reading times of their unambiguous counterparts, even in unpreferred and conflicted context conditions. However, time to read a following region, which forced the direct object interpretation, was affected by the interaction of verb subcategorization ambiguity and contextual support. The full pattern of results do not fit well with either an unelaborated single-analysis (“garden path”) model or a competitive constraint-satisfaction model, but are consistent with a race model in which multiple factors affect the speed of constructing a single initial analysis.     

Self‐Priming in Production: Evidence for a Hybrid Model of Syntactic Priming

Syntactic priming in language production is the increased likelihood of using a recently encountered syntactic structure. In this paper, we examine two theories of why speakers can be primed: error‐driven learning accounts (Bock, Dell, Chang, & Onishi, 2007; Chang, Dell, & Bock, 2006) and activation‐based accounts (Pickering & Branigan, 1999; Reitter, Keller, & Moore, 2011). Both theories predict that speakers should be primed by the syntactic choices of others, but only activation‐based accounts predict that speakers should be able to prime themselves. Here we test whether speakers can be primed by their own productions in three behavioral experiments and find evidence of structural persistence following both comprehension and speakers’ own productions. We also find that comprehension‐based priming effects are larger for rarer syntactic structures than for more common ones, which is most consistent with error‐driven accounts. Because neither error‐driven accounts nor activation‐based accounts fully explain the data, we propose a hybrid model.     

Representing Radcliffe: Perceptions and Consequences of Social Class

Using retrospective data from a sample of women who graduated from Radcliffe College in 1964, this paper examines the perceptions (what women notice) and consequences (how it makes them feel) of social class during college in these women's lives. The majority of women acknowledged that social class was salient at Radcliffe by stating so directly, by noticing members of different class groups, and/or by mentioning their own class backgrounds. In addition, women consistently perceived two markers of social class: exclusivity and the differences between public and private high school graduates. Surprisingly, there were no differences by social class background in the rates of these perceptions; social class indicators were equally apparent to women from different social class backgrounds. However, most commonly among women from working-class backgrounds, there were psychological consequences of social class that were manifested in feeling bad about themselves. In order to understand the psychology of social class most fully, it seems important to distinguish between perception and consequence in the psychological study of social class, and to pay attention to the impact not only of people's backgrounds, but of social class cues in the environments in which they operate.     

Regression Mixture Models: Does Modeling the Covariance Between Independent Variables and Latent Classes Improve the Results?

Regression mixture models are increasingly used as an exploratory approach to identify heterogeneity in the effects of a predictor on an outcome. In this simulation study, we tested the effects of violating an implicit assumption often made in these models; that is, independent variables in the model are not directly related to latent classes. Results indicate that the major risk of failing to model the relationship between predictor and latent class was an increase in the probability of selecting additional latent classes and biased class proportions. In addition, we tested whether regression mixture models can detect a piecewise relationship between a predictor and outcome. Results suggest that these models are able to detect piecewise relations but only when the relationship between the latent class and the predictor is included in model estimation. We illustrate the implications of making this assumption through a reanalysis of applied data examining heterogeneity in the effects of family resources on academic achievement. We compare previous results (which assumed no relation between independent variables and latent class) to the model where this assumption is lifted. Implications and analytic suggestions for conducting regression mixture based on these findings are noted.     

低阶层者的系统合理化水平更高吗?——基于社会认知视角的考察

系统合理化理论曾提出,低阶层者比高阶层者具有更高的系统合理化水平,即更认可社会体系的合理性、更支持当前社会系统。但这一论断一直存在争议。研究引入社会认知视角,考察低阶层与高阶层者系统合理化水平的差异及其机制。两个分研究得到了共同的结果:(1)低阶层者的系统合理化水平显著低于高阶层者;(2)这一差异是通过贫富归因的中介作用实现的,低阶层者系统合理化水平较低是基于其更少地认为社会贫富差距是由个人内部因素所致;(3)这一中介作用会受到个体控制感水平的调节,当控制感较低时,上述中介作用成立;但当控制感较高时,低阶层会弥合与高阶层贫富归因的差异,中介模型不成立。这些结果支持并发展了系统合理化的认知途径解释和阶层社会认知理论这两个立足于社会认知的理论观点,显示了认知因素在此问题中的重要作用,构建了更整合的阶层—归因—合理化的逻辑,并考虑了其边界因素,对于了解低阶层者的社会心态及其形成机制,包括如何改变此状况,均有一定的现实启示意义。
