Information processing in reading-disabled and nondisabled children

Reading disabled and nondisabled children (13-14 years of age) were presented lists of 10 words each at different rates (one word per 1, 2, and 4 sec), and immediately after the last word of each list they recalled the words in any order. Recall of the first few words presented from each list (the primacy effect) was lower in reading-disabled than nondisabled children, and slower presentation rates increased the primacy effect in both groups. These findings suggest that reading-disabled children are not completely failing to use elaborative encoding but are using less effective elaborative encoding than nondisabled readers. With all presentation rates, recall of the last few words (the recency effect) was comparable in both groups, suggesting that older reading-disabled children encode and recognize the stimuli and that elaborative encoding is deficient in reading-disabled in spite of adequate stimulus encoding and recognition.     

Testing models for the structure of vocational interests

Several studies aimed at testing the validity of Holland's hexagonal and Roe's circular models of interests showed results on which the null hypothesis of random arrangement can be rejected, and the investigators concluded that the tested models were supported. None of these studies, however, tested each model in its entirety. The present study is based on the assumption that the rejection of the null hypothesis of chance is not rigorous enough. Reanalysis of 13 data sets of published studies, using a more rigorous method, reveals that although the random null hypothesis can in fact be rejected in 11 data sets, the hexagonal-circular model was supported by only 2 data sets and was rejected by 11 data sets. The hierarchical model for the structure of vocational interests (I. Gati, Journal of Vocational Behavior, 1979, 15, 90–106) was submitted to an identical test and was supported by 6 out of 10 data sets, including 4 data sets that rejected the hexagonal-circular model. The predictions of each of the models which tend to be discontinued by empirical data were identified. The implications of the findings for the structure of interests and occupational choice are discussed.     

When what is said is important: A comparison of expert and attractive sources

Ninety-eight female subjects were presented with a statement made by an attractive or an expert source suggesting that people should sleep less than the usual eight hours. For approximately half of the subjects the source gave a simple statement of opinion, for the other half six separate supporting arguments were also presented. As predicted the manipulation of number of arguments provided had more influence on the effectiveness of the expert than the attractive source. Results were interpreted as supporting the hypothesis that quite different dynamics underly the persuasive power of attractive and expert individuals.     

Moderators of Mood-congruent Encoding and Judgement: Evidence that Elated and Depressed Moods Implicate Distinct Processes

An experiment investigated the contributions of elaborative processes to mood-congruent encoding (MCE) and judgement (MCJ) of trait adjectives that referred to the self and two others. Evidence from multiple sources (recall, judgement, decision latency) supported the main hypotheses: Elated mood produces MCE/MCJ through elaborative processes that implicate mood-congruent self-schemata; depressed mood produces MCE/MCJ through elaborative, but nonschematically based, processing of self-referent material; and, elated mood produces MCJ (but not MCE) of positive material that referred to the experimenter through simplified or heuristic (rather than elaborative) processing. The hypothesis that elated mood produces MCE/ MCJ through elaborative, but nonschematically based, processing of friendreferent material did not receive support; instead, the results suggested that mood-congruent schemata about the friend also contributed to both the encoding and judgement effects of elated mood.     

句子结构与控制动词类型对题元角色指派的影响

扩展论元依存模型认为：语序固定语言的题元角色指派依赖论元的语序线索; 论元线索与动词论元表征不一致时, 题元角色再分析会产生额外的加工负荷。为检验该模型, 本研究采用眼动记录方法, 实验为2 (句子结构：居中、前置) × 2 (控制动词类型：主语控制、宾语控制)被试内设计。通过操纵句子结构, 考察汉语读者对语序线索的依赖性; 通过操纵控制动词类型, 考察汉语论元线索与动词论元表征的一致性对题元角色指派的影响。结果发现：(1)前置结构的句子在名词1、名词2和动词区域的阅读时间和回视次数多于居中结构的句子; (2)宾语控制动词条件在动词和动词后区域的第二遍阅读时间和总回视次数多于主语控制动词条件; (3)在居中结构中, 宾语控制动词条件在名词2和动词区域的阅读时间和回视次数多于主语控制动词条件; 在前置结构中, 宾语控制动词条件在动词后区域的阅读时间多于主语控制动词条件。结果支持扩展论元依存模型。     

A disposition-behavior congruity model of perceived freedom

Three experiments were conducted to test a disposition-behavior congruity model of perceived freedom. The model was applied to attributions of freedom to actors who possess one of several dispositions and who can choose a behavior that is congruent or incongruent with this disposition. The model posits that attributions of freedom to an actor can be predicted from the conditional probabilities that the actor would choose each behavior available to him if he possessed the disposition congruent with it. This hypothesis was supported. However, contrary to expectations, the contribution to judgment of each conditional probability was not a function of the probability that the actor actually possessed the behavior-congruent disposition.     

The Appeal to Expert Opinion: Quantitative Support for a Bayesian Network Approach

The appeal to expert opinion is an argument form that uses the verdict of an expert to support a position or hypothesis. A previous scheme‐based treatment of the argument form is formalized within a Bayesian network that is able to capture the critical aspects of the argument form, including the central considerations of the expert's expertise and trustworthiness. We propose this as an appropriate normative framework for the argument form, enabling the development and testing of quantitative predictions as to how people evaluate this argument, suggesting that such an approach might be beneficial to argumentation research generally. We subsequently present two experiments as an example of the potential for future research in this vein, demonstrating that participants' quantitative ratings of the convincingness of a proposition that has been supported with an appeal to expert opinion were broadly consistent with the predictions of the Bayesian model.     

The role of animacy in the real time comprehension of Mandarin Chinese: Evidence from auditory event-related brain potentials

Two auditory ERP studies examined the role of animacy in sentence comprehension in Mandarin Chinese by comparing active and passive sentences in simple verb-final (Experiment 1) and relative clause constructions (Experiment 2). In addition to the voice manipulation (which modulated the assignment of actor and undergoer roles to the arguments), both arguments were either animate or inanimate. This allowed us to examine the interplay of animacy with thematic interpretation. In Experiment 1, we observed no effect of animacy at NP1, but N400 effects for inanimate actor arguments in second position. This result mirrors previous findings in German, thus suggesting that an initial undergoer universally leads to the prediction of an ideal (animate) actor. We also observed an N400 effect for passive sentences with an inanimate initial (undergoer) argument. We attribute this effect to a language-specific property of the passive construction in Chinese, namely that the first argument is negatively affected by the event described (i.e. bears an experiencer role). Experiment 2 showed that both of these effects can also be observed in sentence constructions of another type, in which the critical information sources become available in a different order. These findings provide the first demonstration that the N400 is not only sensitive to general (universal) aspects of thematic processing (i.e. "who is acting on whom") but also to the interaction between thematic interpretation and language-specific pragmatic principles.     

The effects of contrastive encoding of semantic information on children's memory for words

The effect of context-sensitive contrastive encoding of semantic item information at input on children's memory for words is examined. In two experiments, second and fifth graders and college adults were presented with word triplets varying in categorical relatedness. Each triplet contained a target item (eg., canary) that was highly related (hawk, eagle, canary), moderately related (goose, swan, canary), or unrelated (river, lake, canary) to the other triplet members. Subjects were required to either isolate and remember the odd target word (oddity encoding) or simply read and remember the word identified by the experimenter (read encoding). Both recall and recognition were tested. The results showed that recall and recognition varied as a function of decision difficulty in isolating the target members. Developmental differences in both absolute retention levels and the patterns associated with decision difficulty were maximized in the read and minimized in the oddity encoding condition. This suggests that children differ from adults in the degree to which they perform distinctive contrastive encoding of item specific information at input, and that retention varies as a result.     

The development of elaborative propensity in adolescence

A series of three experiments was conducted to verify the hypothesis that age differences in paired-associate learning proficiency across adolescence stem from the development of increasing elaborative propensity. An auxiliary aim was to determine whether previous study-to-study discrepancies in the pertinent age functions should be attributed to corresponding variations in learning materials or in characteristics of the populations sampled. Taken together, the results of the experiments provided support for the hypothesis. They also indicated, however, that students in late adolescence vary markedly in elaborative propensity, to the point that a substantial proportion of them are hardly distinguishable from preadolescents.     

Object superiority as a function of object coherence and task difficulty

This study addressed the view that object superiority depends on the informativeness or task relevance of particular contexts. It was hypothesized that target search is facilitated to the extent that global properties of a complex stimulus provide informative cues to target location. Results of Experiments 1 and 2 showed that when the target appeared at variable relative positions it was identified better in a coherent context than in an incoherent one. Because the coherent context was presumed to contain informative global cues to location, the results confirmed the hypothesis. Experiment 2 also indicated that when only informative local properties were available, search was facilitated, albeit to a lesser extent than when global properties were available. Overall, the results extend the informativeness view of object superiority effects.     

Piaget's theory of space perception in infancy.

Piaget's theory of space perception in infancy is presented in the format of a hypothetico-deductive system. Eleven hypotheses are defined, regarding the perception of the agent of visual change; shape and size constancy; depth; and the perception of higher-order relationships among spatial elements. The proof Piaget offers for each hypothesis is presented in the following steps: behavioral evidence, interpretation in terms of inner states; inferences and generalizations. Presuppositions underlying the arguments are explicated. Critical notes are inserted whenever appropriate. Some general conclusions are briefly discussed.     

Judgments of grammaticality of Japanese simple sentences involving two arguments in a whole-part relation: a further examination of Chomsky's principle of Full Interpretation

Adult Japanese speakers judged the grammaticality of simple ungramatical sentences involving two arguments, each related with a single verb. The arguments were attached to the same case marker playing the same thematic role in the sentences. Thus the sentences violated Chomsky's principle of Full Interpretation. The two arguments were manipulated such that, on the one hand, one argument (the part-argument) constituted a part of the other argument (the whole-argument) and that, on the other, a part-argument either preceded or followed a whole-argument. Participants rated the sentences using either a conventional 7-point rating scale or magnitude estimation. Findings showed that irrespective of rating method sentences in which the whole-argument preceded the part-argument were judged more grammatical than sentences in which the part-argument preceded the whole-argument. Such an empirical phenomenon is inconsistent with the prediction derived from Chomsky's principle of Full Interpretation, while interestingly it is consistent with the grammar of classical Japanese used about 900 years ago.     

Access to attitude-relevant information in memory as a determinant of persuasion: The role of message attributes

Recipients with access to attitude-relevant information in memory were thought to draw on these beliefs and prior experiences to evaluate the validity of message arguments. Consistent with this idea, persuasion for these recipients was largely a function of the perceived validity of message content: Messages containing high-quality arguments were more persuasive than messages containing lowquality arguments, whereas variations in a structural attribute of the message (its length) proved to have little impact on opinion change. In contrast, people who tend to retrieve little attitude-relevant information were believed to be less able to evaluate the validity of message arguments in terms of information accessed from memory. Instead, it was anticipated that they would base their opinion judgments on a more superficial analysis of persuasion cues, focusing on attributes like message length. Consistent with this reasoning, these recipients were more persuaded by long than short messages. Recipients with moderate levels of retrieval functioned much like the high-retrieval subjects.     

Information-gathering strategies in hypothesis-testing

Three experiments were conducted to investigate the informational factors affecting the kinds of questions people ask for testing a hypothesis about another's personality. In Experiment 1, subjects formulated by themselves questions to test either the hypothesis that the interviewee is polite or the hypothesis that he is impolite. The boundary of the hypothesis was set either at an extreme or at an intermediate point on the trait dimension. Experiment 2 also varied the location of the boundary, but the hypotheses concerned extroversion-introversion and subjects chose questions from a predetermined list of questions that asked either about extroverted features or introverted features and that were either low or high in diagnostic value. Both studies found that subjects preferred to ask about features that are consistent with the hypothesis only when the boundary was extreme. In contrast, diagnostic features were preferred in all conditions. Experiment 3 showed that subjects' judgment of the diagnosticity of the various kinds of questions for discriminating at different boundaries paralleled subjects' preferences among these questions. These results were interpreted as providing support for the diagnostic strategy in social information gathering.     

Interpersonal comparison versus persuasive argumentation: A more direct test of alternative explanations for group-induced shifts in individual choice

One class of theories explains group induced shifts in individual choice in terms of interpersonal comparison process. By comparing himself with others a member finds out that his position is uncomfortably discrepant, e.g., he is overly “cautious” or overly “risky”. Knowledge of this discrepancy presumably is necessary and sufficient to induce him to change his initial choice. Another class of theories holds that merely knowing one is different from others is unimportant. Shifts in choice occur because during discussion a member is exposed to persuasive arguments which prior to discussion were not available to him. Thus, if in a factorial design one independently varied (a) the number of others' choices available for comparison and (b) the number of arguments others presented in support of these choices, interpersonal comparison theories would predict the magnitude of the shift to be a function of (a) and not of (b), while theories of persuasive argumentation would predict the opposite. When such an experiment was performed the only reliable main effects were based on the number of arguments, (b), as predicted by persuasive arguments. In no instance did effects involving (a) approach significance.
