基于语境的因果性预期推理的构建的实验研究

实验一探讨对因果性预期推理的支持程度不同的语境对因果性预期推理的即时构建的影响。结果表明,如果文本信息有支持预期结果的语境,读者会即时进行因果性预期推理。实验二探讨当文本描述了两个不能整合的情境模型时因果性预期推理的即时构建情况。结果表明,在这种条件下,因果性预期推理不会即时产生。本研究结果表明,文本的语境对因果性结果的支持程度对因果性预期推理的即时构建有决定性的影响作用。     

长时记忆中目标信息的即时性通达

采用移动窗口技术和探测词再认技术,探讨文本阅读过程中长时记忆中目标信息的即时性通达。实验1探讨当原目标尚未实现,新目标处于活跃状态,进入长时记忆的未实现的原目标是否对当前阅读产生影响。实验2探讨当原目标已经实现,新目标处于活跃状态,进入长时记忆的已实现的原目标是否对当前阅读产生影响。本实验结果初步证明,在含有目标信息的文本阅读中,未实现的原目标信息和已实现的目标信息都处于活跃状态,一旦出现与原目标焦点有关的信息,就会被通达与当前的信息进行整合,只是已实现的目标信息比未实现的目标信息通达的程度低。     

篇章阅读中影响回指推理的因素

探讨回指距离、干扰词的精细描述、干扰词的典型性对回指推理的影响。包括2个实验,164名大学生被试。实验1探讨干扰词精细描述类型的影响。结果表明,干扰的精细描述并非是影响回指推理的主要因素。实验2探讨干扰词和先行词的典型性类型的相对变化的影响。结果表明高典型干扰在不同回指距离条件下都会对回指推理产生影响。从而表明高典型的干扰项干扰了回指推理发生。     

Specifying the boundary conditions of the multimedia effect: The influence of content and its distribution between text and pictures

It was investigated whether the beneficial effect of picture presentation might be influenced by the content conveyed through text and pictures and the way information is distributed between them. Ninety‐nine students learnt in five between‐subjects learning conditions (i.e., text with spatial contents plus pictures, text with visual contents plus pictures, only text with spatial contents, only text with visual contents, only picture) about a tourist centre and a holiday farm. Results showed that pictures (i.e., maps) were beneficial for learning if spatial knowledge had to be acquired, but did not support learning when non‐spatial, visual knowledge had to be acquired. Furthermore, a high overlap of spatial information in text and picture was helpful, which can be explained by the assumption that learning is a text‐guided process. On the other hand, regarding non‐spatial visual information, a high text‐picture overlap did not influence learning, probably because text alone was sufficient for acquiring visual knowledge. The implications of these findings are discussed.     

Social categorization and individuation in the own‐age bias

Young adults recognize other young adult faces more accurately than older adult faces, an effect termed the own‐age bias (OAB). The categorization‐individuation model (CIM) proposes that recognition memory biases like the OAB occur as unfamiliar faces are initially quickly categorized. In‐group faces are seen as socially relevant which motivates the processing of individuating facial features. Outgroup faces are processed more superficially with attention to category‐specific information which hinders subsequent recognition. To examine the roles of categorization and individuation in the context of the OAB, participants completed a face recognition task and a speeded age categorization task including young and older adult faces. In the recognition task, half of the participants were given instructions aimed to encourage individuation of other‐age faces. An OAB emerged that was not influenced by individuation instructions, but the magnitude of the OAB was correlated with performance in the categorization task. The larger the categorization advantage for older adult over young adult faces, the larger the OAB. These results support the premise that social categorization processes can affect the subsequent recognition of own‐ and other‐age faces, but do not provide evidence for the effectiveness of individuation instructions in reducing the OAB.     

A cluster analysis of text message users based on their demand for text messaging: A behavioral economic approach

The goal of this study was to determine whether cluster analysis could be used to identify distinct subgroups of text message users based on behavioral economic indices of demand for text messaging. Cluster analysis is an analytic technique that attempts to categorize cases based on similarities across selected variables. Participants completed a questionnaire about mobile phone usage and a hypothetical texting demand task in which they indicated their likelihood of paying an extra charge to continue to send text messages. A hierarchical cluster analysis was conducted on behavioral economic indices, such as demand intensity, demand elasticity, breakpoint, and the maximum expenditure. With the cluster analysis, we identified 3 subgroups of text message users. The groups were characterized by (a) high intensity and low elasticity, (b) high intensity and medium elasticity, and (c) low intensity and high elasticity. In a demonstration of convergent validity, there were statistically significant and conceptually meaningful differences across the subgroups in various measures of mobile phone use and text messaging. Cluster analysis is a useful tool for identifying and profiling distinct, practically meaningful groups based on behavioral indices and could provide a framework for targeting interventions more efficiently.     

The big two dictionaries: Capturing agency and communion in natural language

Four studies developed and validated two dictionaries to capture agentic and communal expressions in natural language. Their development followed the Linguistic Inquiry and Word Count (LIWC) approach (Study 1) and we tested their validity with frequency-based analyses and semantic similarity measures. The newly developed Agency and Communion dictionaries were aligned with LIWC categories related to agency and communion (Study 2), and corresponded with subjective ratings (Study 3), confirming their convergent validity. Very low or absent correspondence between proposed dictionaries and unrelated LIWC categories demonstrated their discriminant validity (Study 2). Finally, we applied both dictionaries to language used in advertisements. In correspondence to gender stereotypes, male-dominated jobs were advertised with more agentic than communal words, and female-dominated jobs with more communal than agentic words (Study 4). Both dictionaries represent reliable tools for quantifying agentic and communal content in natural language, and will improve and facilitate future research on agency and communion.     

Happy but overconfident: positive affect leads to inaccurate metacomprehension

When learning from text, it is important that learners not only comprehend the information provided but also accurately monitor and judge their comprehension, which is known as metacomprehension accuracy. To investigate the role of a learner’s affective state for text comprehension and metacomprehension accuracy, we conducted an experiment with N?=?103 university students in whom we induced positive, negative, or neutral affect. Positive affect resulted in poorer text comprehension than neutral affect. Positive affect also led to overconfident predictions, whereas negative and neutral affect were both associated with quite accurate predictions. Independent of affect, postdictions were rather underconfident. The results suggest that positive affect bears processing disadvantages for achieving deep comprehension and adequate prediction accuracy. Given that postdictions were more accurate, practice tests might represent an effective instructional method to help learners in a positive affective state to accurately judge their text comprehension.
