Are the visual word-processing tasks of naming and lexical decision sensitive to systematic phonological properties that may or may not be specified in the spelling? Two experiments with Hangul, the alphabetic orthography of Korea, were directed at the effects of the phonological process of assimilation whereby one articulation changes to conform to a neighboring articulation. Disyllabic words were responded to more quickly when (a) the final letter of the first syllable and the initial letter of the second syllable specified phonemes that satisfied rather than violated consonant assimilation, and (b) the vowel letters specified harmonious as opposed to disharmonious vowel phonemes. Discussion addressed the possible mediation of assimilation effects by consistency differences and theories that predict broad phonological influences on visual word recognition. 相似文献

This research investigated how working models of attachment are carried forward from one relationship to the next. A two-part study was conducted in which participants learned about two potential dating partners: one that was constructed to resemble a romantic partner from their past and one that resembled a partner from another participant's past. Results showed that people applied their attachment representations of past partners to both targets but did so to a greater degree when the target resembled a past partner. People also tended to feel more anxious and less avoidant toward the target that resembled their past partner. Overall, the findings were consistent with the hypothesis that working models of attachment are transferred in both general and selective ways in new relationships. 相似文献

This paper is a critical overview of the literature on older adults' outcome after traumatic brain injury (TBI). Eighteen outcome studies were reviewed. Results indicated that older patients demonstrated an increased risk for negative outcome following TBI when compared to younger patients with similar injury severity. Poorer outcome was characterized by higher mortality rates, decreased likelihood of returning to preinjury living arrangement, and declines in cognitive and affective functioning. In the studies reviewed, discharge destination, global outcome scales, and standardized neuropsychological tests were the primary measures of outcome from elderly TBI. Conceptual and methodological difficulties including variability in the definition of and inadequate measures of recovery from elderly TBI, inadequate control groups, and poor follow-up were discussed. Recommendations for future outcome research to increase uniformity in defining recovery in order to enhance comparability between studies and to tailor cognitive rehabilitation to the special needs of the older TBI patient were provided. 相似文献

Verb-object phrases (open the umbrella, knock on the table) are usually remembered better if they have been enacted during study (also called subject-performed tasks) than if they have merely been learned verbally (verbal tasks). This enactment effect is particularly pronounced for phrases for which the objects (table) are present as cues in the study and test contexts. In previous studies with retrieval cues for some phrases, the enactment effect in free recall for the other phrases has been surprisingly small or even nonexistent. The present study tested whether the often replicated enactment effect in free recall can be found if none of the phrases contains context cues. In Experiment 1, we tested, and corroborated, the suppression hypothesis: The enactment effect for a given type of phrase (marker phrases) is modified by the presence or absence of cues for the other phrases in the list (experimental phrases). Experiments 2 and 3 replicated the enactment effect for phrases without cues. Experiment 2 also showed that the presence of cues either at study or at test is sufficient for obtaining a suppression effect, and Experiment 3 showed that the enactment effect may disappear altogether if retrieval cues are very salient. 相似文献

Heuristics are mental shortcuts that aid people in everyday problem-solving and decision-making. Although numerous studies
have demonstrated their use in contexts ranging from consumers’ shopping decisions to experts’ estimations of experimental
validity, virtually no published research has addressed heuristics use in problems involving genetic conditions and associated
risk probabilities. The present research consists of two studies. In the first study, 220 undergraduates attempted to solve
four genetic problems—two common heuristic problems modified to focus on genetic likelihood, and two created to study heuristics
and probability rule application. Results revealed that the vast majority of undergraduates used heuristics and also demonstrated
a complete misuse of probability rules. In the second study, 156 practicing genetic counselors and 89 genetic counseling students
solved slightly modified versions of the genetic problems used in Study 1. Results indicated that a large percentage of both
genetic counselors and students used heuristics, but the counselors demonstrated superior problem-solving performance compared
to both the genetic counseling students and the undergraduates from Study 1. Research, training, and practice recommendations
are presented. 相似文献

Cultural illiteracy and the Internet. 总被引:1,自引:0,他引:1
The Internet has created different expectations regarding its possibilities as a tool for including groups that have heretofore been excluded from the modern world. But mere access to information does not necessarily imply correct and effective use of it. Despite the great increase in Internet access in previously excluded areas, expectations of inclusion have not been fulfilled. Research suggests that the effectiveness of Internet use varies among cultures, but all such studies analyze countries as a whole with no further breakdown. Yet it is known that within a given country there co-exist subcultures that differ both in language and social context. This paper presents a study that shows the correlation between different social subcultures and their Internet knowledge. 相似文献

In this study we investigated in a Simon-like task whether task-irrelevant spatial information, delivered by centrally presented patterns, interfered with response selection in the same way as laterally presented stimuli. Second, we asked whether such interference was equal for different kinds of stimuli. Participants were required to respond to the colour of two framed squares, two arrows, or two schematic eyes by pressing one of two lateralized response keys. The results consistently show that the Simon effect occurs independently of the nature of the stimulus, as classically reported for lateralized stimuli. Response times were influenced by the direction and frame-relative position of the stimuli, being faster for responses corresponding to the direction indicated by the stimuli than for noncorresponding responses regardless of stimulus types. Contrary to findings with lateralized nondirectional stimuli, such an effect increased with increasing RTs indicating that for centrally presented patterns the extraction of spatial information is time consuming. 相似文献

Evaluation point feedback was used to align confidence judgments with accurate/inaccurate responding to general knowledge questions. Rehearsal of item-answer pairs and three evaluation systems based on a scoring rule had different effects on confidence, accuracy and their relationship. Using standard calibration measures (Yates, J.F., (1990). Judgment and Decision Making. Englewood Cliffs, NJ: Prentice Hall) we found that a point system comprising of both rewarding (positive) and punishing (negative) consequences produced the best performance across levels of knowledge in comparison to all-rewarding and all-penalty rules. 相似文献

To test the domain-specificity of "theory of mind" abilities we compared the performance of a case-series of 11 brain-lesioned patients on a recently developed test of false belief reasoning () and on a matched false photograph task, which did not require belief reasoning and which addressed problems with existing false photograph methods. A strikingly similar pattern of performance was shown across the false belief and false photograph tests. Patients who were selectively impaired on false belief tasks were also impaired on false photograph tasks; patients spared on false belief tasks also showed preserved performance with false photographs. In some cases the impairment on false belief and false photograph tasks coincided with good performance on control tasks matched for executive demands. We discuss whether the patients have a domain-specific deficit in reasoning about representations common to both false belief and false photograph tasks. 相似文献
