Writers typically spend a certain proportion of time looking back over the text that they have written. This is likely to serve a number of different functions, which are currently poorly understood. In this article, we present two systems, ScriptLog+TimeLine and EyeWrite, that adopt different and complementary approaches to exploring this activity by collecting and analyzing combined eye movement and keystroke data from writers composing extended texts. ScriptLog+TimeLine is a system that is based on an existing keystroke-logging program and uses heuristic, pattern-matching methods to identify reading episodes within eye movement data. EyeWrite is an integrated editor and analysis system that permits identification of the words that the writer fixates and their location within the developing text. We demonstrate how the methods instantiated within these systems can be used to make sense of the large amount of data generated by eyetracking and keystroke logging in order to inform understanding of the cognitive processes that underlie written text production.  相似文献

Externalizing, or separating the person from his/her problem-saturated story, is a central approach in narrative therapy. Michael White, one of the therapy’s founders, lately revised his map of the externalizing process in therapy according to Vygotskian theory. In this study we sought to determine whether White’s proposed process was evident in therapy sessions. Sequential analysis indicated that therapists scaffolded children’s responses according to White’s map, and therapists’ and children’s utterances tended to advance across the levels of the map over the course of a session, indicating that White’s model of narrative therapy matched the therapy’s empirical process.  相似文献

The LEXIN database offers psycholinguistic indexes of the 13,184 different words (types) computed from 178,839 occurrences of these words (tokens) contained in a corpus of 134 beginning readers widely used in Spain. This database provides four statistical indicators: F (overall word frequency), D (index of dispersion across selected readers), U (estimated frequency per million words), and SFI (standard frequency index). It also gives information about the number of letters, syntactic category, and syllabic structure of the words included. To facilitate comparisons, LEXIN provides data from LEXESP’s (Sebastián-Gallés, Martí, Cuetos, & Carreiras, 2000), Alameda and Cuetos’s (1995), and Martínez and García’s (2004) Spanish adult psycholinguistic frequency databases. Access to the LEXIN database is facilitated by a computer program. The LEXIN program allows for the creation of word lists by letting the user specify searching criteria. LEXIN can be useful for researchers in cognitive psychology, particularly in the areas of psycholinguistics and education.  相似文献

Drawing on the g factor and information theory literatures, the relationship between the four subtests of the Culture-Fair Intelligence Test (CFIT) and the entropy of the Ruiz Absolute Scale of Complexity Management (R-ASCM) was investigated. In results based on data collected from 186 university students, the entropy of the R-ASCM mostly loads the first principal component extracted from the CFIT subtests and shows a corresponding strong relationship with the item difficulty of the R-ASCM. Because entropy is a ratio scale of complexity— with a true zero and units called bits—these findings suggest that entropy is the right vehicle for measuring the information contained in nonverbal intelligence tests.  相似文献

Although there are many well-known forms of visual cues specifying absolute and relative distance, little is known about how visual space perception develops at small temporal scales. How much time does the visual system require to extract the information in the various absolute and relative distance cues? In this article, we describe a system that may be used to address this issue by presenting brief exposures of real, three-dimensional scenes, followed by a masking stimulus. The system is composed of an electronic shutter (a liquid crystal smart window) for exposing the stimulus scene, and a liquid crystal projector coupled with an electromechanical shutter for presenting the masking stimulus. This system can be used in both full- and reduced-cue viewing conditions, under monocular and binocular viewing, and at distances limited only by the testing space. We describe a configuration that may be used for studying the microgenesis of visual space perception in the context of visually directed walking.  相似文献

Several naming studies show that distractor pictures, even when intentionally ignored by the speaker, are still capable of activating their respective phonological representations. However results from word translation studies suggest that distractor pictures are only conceptually activated. Here we tested the reliability of the word translation results. In four experiments, bilingual participants translated words from one language to the other one while ignoring the presentation of pictures. In Experiment 1a phonological related pictures sped up translation latencies. However, the effect disappeared when the percentage of related trials was reduced (Experiment 1b). In Experiment 2a translation latencies were faster when the words were accompanied by semantically related pictures than by unrelated pictures. Importantly, the effect was still reliable when the proportion of related trials was reduced and the total number of semantic categories was increased (Experiment 2b). Theoretical implications of the influence of distractor pictures during speech production are discussed.  相似文献

Previous studies have shown that bilingual adults use more gestures than English monolinguals. Because no study has compared the gestures of bilinguals and monolinguals in both languages, the high gesture rate could be due to transfer from a high gesture language or could result from the use of gesture to aid in linguistic access. In this study we tried to distinguish between those causes by comparing the gesture rate of 10 French–English bilingual preschoolers with both 10 French and 10 English monolinguals. All were between 4 and 6 years of age. The children were asked to watch a cartoon and tell the story back. The results showed the bilingual children gestured more than either group of monolinguals and at the same rate in both French and English. These results suggest that that the bilinguals were not gesturing because they were transferring the high gesture rate from one language to another. We argue that bilinguals might gesture more than monolinguals to help formulate their spoken message.  相似文献

This study examines the relation between maternal physical discipline and victimization by peers, as moderated by child aggression. The sample consisted of 211 Hong Kong Chinese children (98 boys, 113 girls; average age of 11.9). Physical discipline was assessed with a questionnaire completed by mothers, and victimization by peers and aggression were measured using a peer nomination inventory. Latent variable models revealed a moderately strong link between children’s experiences with maternal physical discipline and peer victimization, but this effect held only for children who were also high on aggression. These results highlight the interplay between harsh home environments and child aggression and their contributions to the child’s adjustment in the peer group.  相似文献

Purpose  The purpose of this study was to investigate the direct and indirect effects of personality characteristics on individual earnings and to examine a person’s leadership role occupancy as the potential mediator in the personality–earnings relationship. Design/Methodology/Approach  Longitudinal survey data were collected from a sample of 209 individuals. Earnings were measured 6 years after the personality variables. Findings  Two personality traits, i.e., Social Potency and Achievement, predict individual earnings longitudinally. The effects of personality were partially mediated by the person’s occupancy of leadership roles in the workplace. For those occupying similar leadership positions, people higher in social potency still have greater earnings. Implications  These findings lend support for personality assessment in personnel selection and have important implications for leadership development and individual career success. Originality/Value  Previous research suggests that personality influences individual earnings beyond the effects of traditional human capital variables. This study is among the first to distinguish personality’s direct and indirect (through leadership role occupancy) effects on individual earnings. The findings provide direct support for the incentive-enhancing property of personality as well as indirect support for the trait activation theory on the personality–earnings relationship.
