Mechanisms underlying skilled anticipation and recognition in a dynamic and temporally constrained domain

We examined the mechanisms underlying skilled anticipation and recognition in a dynamic, interactive, and temporally constrained domain. Skilled and less-skilled participants viewed dynamic film stimuli, anticipated event outcome, and provided immediate retrospective verbal reports. Previously viewed and novel sequences were then presented in film or point-light display format. Participants made recognition judgements and again gave retrospective verbal reports on their thought processes. Skilled participants demonstrated superior anticipation accuracy and were more sensitive in distinguishing previously seen from novel stimuli than less-skilled participants. Skilled participants utilised more complex memory representations than less-skilled individuals, as indicated by references in their retrospective reports to more evaluation and prediction statements. The representations activated during anticipation were more complex than those for recognition judgements in both groups. Findings are discussed with reference to long-term working memory theory.     

The effect of question expectedness and experience on lying about intentions

In recent years researchers have started to focus on lying about intentions (Granhag, 2010). In the present experiment participants were interviewed about their forthcoming trip. We tested the hypothesis that liars (N=43) compared to truth tellers (N=43) would give fewer details to unexpected questions about planning, transportation and the core event, but an equal amount or more detail to expected questions about the purpose of the trip. We also tested the hypothesis that participants who had previously experienced the intention (i.e., they had made such a trip before) would give more detail than those who had never experienced the intended action. The unexpected question hypothesis was supported, whereas the previous experience effect only emerged in interactions. The benefit of using different types of questions for lie detection purposes is discussed.     

A Critique of Howard's Argument for Innate Limits in Chess Performance or Why We Need an Account Based On Acquired Skill and Deliberate Practice

In this issue Howard reported that the effect of chess study is surprisingly small among elite chess players, who continue playing more games in international chess tournaments. In contrast, we show that individual differences in chess study are the likely causes of both higher chess ratings and more chess games played in international tournaments, which is often very costly and includes airfare, hotel, and tournament registration fees. The low correlation between his estimates of study time and chess rating is shown to be a consequence of his methodology of relying on a couple of questions in an internet survey rather than the standard methodology in expert performance research involving a 30‐minute interview tracing yearly engagement in many different practice activities.

Evaluation context's role in driving positive word‐of‐mouth intentions

Relevant literature recognizes that transaction‐specific and cumulative evaluations are different, but few empirical studies test how these differences might affect the link between product evaluations and word of mouth (WOM). This study addresses this issue by assessing the simultaneous effects of perceived quality and satisfaction on the resulting positive WOM intentions for both types of evaluations. Results reveal that different factors drive positive WOM intentions depending on the context of the study. When the consumers' evaluations are related to a specific transaction, perceived quality is the dominating predictor of positive WOM intentions. When the evaluations are cumulative, satisfaction is the dominating predictor of positive WOM intentions. Copyright © 2012 John Wiley & Sons, Ltd.     

A developmental comparison of the effectiveness of encoding tasks.

In Experiment 1, the free-recall performance of young children, college students, and older adults was examined. Subjects encoded words by simply learning them, by studying them in either base or elaborate sentence frames, or by constructing sentences. Overall recall was better for the college students than for the children or for the older adults, and the college students recalled best in the simple learning condition. The young children recalled best in the sentence construction condition; recall by older adults did not vary as a function of the encoding tasks. In Experiment 2, college students and older adults recalled a categorized list, encoding the words by simply learning them, by studying them in elaborate sentence frames, or by completing word fragments. For both age groups, simple learning produced the highest level of recall. These results suggest that organization provides the most effective encoding system and that older adults may need a more obvious basis for organization than do younger adults. Younger and older adults recalled equally well only when organization was discouraged by conceptual processing.     

The Impact of Gender on the Review of the Curricula Vitae of Job Applicants and Tenure Candidates: A National Empirical Study

The purpose of this study was to determine someof the factors that influence outside reviewers andsearch committee members when they are reviewingcurricula vitae, particularly with respect to the gender of the name on the vitae. The participants inthis study were 238 male and female academicpsychologists who listed a university address in the1997 Directory of the American PsychologicalAssociation. They were each sent one of four versions of acurriculum vitae (i.e., female job applicant, male jobapplicant, female tenure candidate, and male tenurecandidate), along with a questionnaire and aself-addressed stamped envelope. All the curricula vitaeactually came from a real-life scientist at twodifferent stages in her career, but the names werechanged to traditional male and female names. Althoughan exclusively between-groups design was used to avoidsparking genderconscious responding, the resultsindicate that the participants were clearly able todistinguish between the qualifications of the jobapplicants versus the tenure candidates, as evidenced bysuggesting higher starting salaries, increasedlikelihood of offering the tenure candidates a job,granting them tenure, and greater respect for theirteaching, research, and service records. Both men andwomen were more likely to vote to hire a male jobapplicant than a female job applicant with an identicalrecord. Similarly, both sexes reported that the male job applicant had done adequate teaching,research, and service experience compared to the femalejob applicant with an identical record. In contrast,when men and women examined the highly competitive curriculum vitae of the real-life scientist whohad gotten early tenure, they were equally likely totenure the male and female tenure candidates and therewas no difference in their ratings of their teaching, research, and service experience. There was nosignificant main effect for the quality of theinstitution or professional rank on selectivity inhiring and tenuring decisions. The results of this study indicate a gender bias for both men and womenin preference for male job applicants.     

The Perceptual Pathway: Tracing the Mechanisms of Political Value Transfer across Generations

The transfer of political values across generations is commonly understood as a two-step process. First, the child perceives the characteristics of the parent, thereby creating an image of what the parent is like. Second, the child is persuaded to adapt his or her own views to that image. Despite its theoretical dominance, the details of this perceptual pathway of parentalsocialization have rarely been examined empirically. A major Swedish socialization study offers unusually good opportunities to investigate how it actually operates. The results indicate that the perceptual pathway as a whole is of great but not universal significance, that perception is more important than persuasion because of its greater variability, and that the conditions regulating the former are distinct from those regulating the latter. One implication of the results is that studies of interpersonal influence based on a single source (e.g., the child alone) are likely to yield a very lopsided view of the socialization process.     

The Importance of Item Selection in "Knew-It-All-Along" Studies of General Knowledge

This study was designed to investigate the effects of item sampling on hindsight bias in experiments using general knowledge material. The results show that the use of random versus traditional experimenter-selected item samples can have different effects on hindsight bias. In a within-subjects study almost twice as many items in a random sample were connected with a reversed effect rather than with a traditional hindsight bias. The same items that resulted in overconfidence in foresight lead to a higher degree of hindsight bias than others. The results suggest that earlier findings of unusually large hindsight effects with general knowledge tasks may be explained by the selection of items used. No hindsight effect was found on confidence scores in a within-subjects design, but was obtained in a between-subjects design. Results suggest that the use of a within-subjects design itself can moderate hindsight bias by familiarizing subjects with the task. The study shows the importance of two conditions for decreasing the hindsight bias: (1) The use of randomly sampled items, and (2) The use of a within-subjects procedure. When these conditions were met, the "knew-it-all-along effect" was completely eliminated.     

COMPARATIVE STUDIES OF SENSORY RELATEDNESS OF ODOURS

Measures of relatedness of odours were obtained by means of two psychophysical methods and one electrophysiological technique. The psychophysical data consisted of similarity judgments and confusion measures. The electrophysiological data were based upon statistical treatment of the responses of single units in the olfactory bulb of the frog. Significant rank correlations were obtained between the results of the three methods. The significance of psychological relatedness data for the study of basic receptor processes is discussed.     

Repeated interrogations: verbal and non‐verbal cues to deception

The major aim of this study was to investigate to what extent verbal and non‐verbal features of liars' and truth‐tellers' behaviour change during the course of repeated interrogations. After seeing a staged event, 24 suspects (12 liars and 12 truth‐tellers) were interrogated three times over a period of 11 days. In terms of the non‐verbal features, and in line with our prediction, we found that the liars displayed significantly fewer smiles, self‐manipulations, pauses, and less gaze aversion than truth‐tellers. Furthermore, over time the initial differences between liars' and truth‐tellers' non‐verbal behaviour increased for smiles, gaze aversion and pauses. In addition, we found that the cue ‘richness of detail’—the most indicative verbal marker for truth as given in previous research—had no discriminative power at any of the interrogation sessions. Finally, and in contrast to beliefs held by supposed expert lie‐catchers (e.g. judges and police officers), truthful and deceptive statements were found to be equally consistent over time. The psycho‐legal implications of the above findings are discussed. Copyright © 2002 John Wiley & Sons, Ltd.
