The ability to keep track of locations in a dynamic, multimodal environment is crucial for successful interactions with other people and objects. The authors investigated the existence and flexibility of spatial indexing in adults and 6-month-old infants by adapting an eye-tracking paradigm from D. C. Richardson and M. J. Spivey (2000). Multimodal events were presented in specific locations, and eye movements were measured when the auditory portion of the stimulus was presented without its visual counterpart. Experiment 1 showed that adults spatially index auditory information even when the original associated locations move. Experiments 2 and 3 showed that infants are capable of both binding multimodal events to locations and tracking those locations when they move. 相似文献

Understanding print: early reading development and the contributions of home literacy experiences 总被引:2,自引:0,他引:2
Levy BA Gong Z Hessels S Evans MA Jared D 《Journal of experimental child psychology》2006,93(1):63-93
This study explored the development of children's early understanding of visual and orthographic aspects of print and how this is related to early reading acquisition. A total of 474 children, ages 48 to 83 months, completed standardized measures of phonological awareness and early reading skills. They also completed experimental tasks that tapped their understanding of what constitutes "readable" print. The parents of participants completed a questionnaire regarding their children's home literacy experiences. The data showed systematic development in children's understanding of print conventions and English orthography and spelling. Regression analyses indicated that print knowledge was related to early reading skill, even after accounting for variance due to age and phonological awareness. Furthermore, parents' ratings of the extent of their children's involvement in activities that led to practice in reading and writing most consistently predicted the development of emerging literacy skills, including understanding of the conventions of the English writing system. Little relation between print knowledge and the frequency of storybook reading by adults was observed. 相似文献

A theory of how individuals construct mental models to draw inferences from single premises was tested in three experiments. Experiment 1 confirmed a counterintuitive prediction that it is easier to generate inferences between conditionals and disjunctions than it is to evaluate them. Experiment 2 replicated this finding, but an advantage found in the first experiment for conditional-to-disjunction over disjunction-to-conditional inferences was removed with different sentence contents. Experiment 3 showed that disjunction-to-conditional inferences were facilitated when premises expressed familiar indicative relations, whereas conditional-to-disjunction inferences were facilitated when premises expressed causal relations. The results indicate that small changes in task format can have large effects on the strategies that people use to represent and reason about different sentential connectives. We discuss the potential for theories other than mental models to account for these results. We argue that, despite the important role played by single-premise inferences in paraphrasing logical forms during inference, mental logic theories cannot account for the results reported here. 相似文献

We report neurological information and experimental data regarding acquired neurogenic stuttering in a 57-year-old male following ischemic lesion to the orbital surface of the right frontal lobe and the pons. The experimental data consist of stuttering frequency measures under various conditions that are well known to enhance fluency in most individuals with developmental stuttering. Specifically, we report data for adaptation, unison reading, delayed auditory feedback (DAF), and frequency altered feedback (FAF). This work is the first published report of such a comprehensive examination of a variety of fluency-enhancing conditions in acquired stuttering. The patient read six 200-word texts under different conditions: Six solo readings (Text 1), five unison readings followed by five solo readings (Text 2), five readings with non-altered auditory feedback (Text 3), five readings with 50 ms delayed auditory feedback (Text 4), five readings with increased FAF (Text 5), and five readings with decreased FAF (Text 6). Results indicate that, unlike the typical situation for developmental stuttering, this individual with acquired neurogenic stuttering did not show increased fluency during an adaptation paradigm or under unison, DAF, and FAF conditions. We discuss possible implications of these findings and emphasize the need for further research on acquired neurogenic stuttering. 相似文献

Within alphabetic languages, spelling-to-sound consistency can differ dramatically. For example, English and German are very similar in their phonological and orthographic structure but not in their consistency. In English the letter a is pronounced differently in the words bank, ball, and park, whereas in German the letter a always has the same pronunciation (e.g., Ball, Park, Bank). It is often argued that reading acquisition has a reciprocal effect on phonological awareness. As reading is acquired, therefore, spoken language representation may be affected differently for English and German children. Prior to literacy acquisition, however, phonological representation in English and German children should be similar due to the similar phonological structure of the two languages. We explored this hypothesis by comparing phonological awareness at the rime and phoneme levels in prereaders and beginning readers in English and German. Similar developmental effects were indeed observed in prereaders, but differential effects had emerged within the first year of reading instruction. 相似文献

Previous research has demonstrated that people's movements can become unintentionally coordinated during interpersonal interaction. The current study sought to uncover the degree to which visual and verbal (conversation) interaction constrains and organizes the rhythmic limb movements of coactors. Two experiments were conducted in which pairs of participants completed an interpersonal puzzle task while swinging handheld pendulums with instructions that minimized intentional coordination but facilitated either visual or verbal interaction. Cross-spectral analysis revealed a higher degree of coordination for conditions in which the pairs were visually coupled. In contrast, verbal interaction alone was not found to provide a sufficient medium for unintentional coordination to occur, nor did it enhance the unintentional coordination that emerged during visual interaction. The results raise questions concerning differences between visual and verbal informational linkages during interaction and how these differences may affect interpersonal movement production and its coordination. 相似文献

This article describes the collaborative effort of a team of discipline directors, administrators, and academicians to create a systematic program to enhance the group competencies of a large clinical staff working at a state hospital. The effects of the program were tested by a quasi-experimental field study. Quantitative measures of group process provided limited support for program effectiveness. Stronger support came from qualitative inquiry. The development and effectiveness of the program is examined within a larger context of group programs housed in large health care organizations. 相似文献

Several recent studies with rats (Sprague-Dawley strain) have documented that an odor previously paired with shock potentiates the acoustic startle response, a phenomenon referred to as conditioned odor potentiation of startle (OPS). A surprising finding in these studies was that OPS did not extinguish even though the odor was present throughout the 25-min test session. Therefore, the present study more fully examined extinction of OPS. The results of Experiment 1, which employed both within-subject and between-group comparisons, showed that extinction of OPS occurred in adult rats only after several days of testing. Experiment 2 used the between-group procedure and found similar results with 23-day-old rats, the youngest age that exhibits the OPS effect. Experiment 2 also showed that giving rats 15 odor-shock pairings at 16 days of age, an age where they acquire the odor-shock association but cannot express it via OPS, does not increase subsequent resistance to extinction following odor-shock pairings at 23 days of age. Taken together, the results of this study show that (1) although OPS is somewhat resistant to extinction, it does extinguish with repeated tests and (2) suggests that there are no age differences in the rate of extinction of OPS. 相似文献

Homophone effects in lexical decision 总被引:6,自引:0,他引:6
Pexman PM Lupker SJ Jared D 《Journal of experimental psychology. Learning, memory, and cognition》2001,27(1):139-156
The role of phonology in word recognition was investigated in 6 lexical-decision experiments involving homophones (e.g., MAID-MADE). The authors' goal was to determine whether homophone effects arise in the lexical-decision task and, if so, in what situations they arise, with a specific focus on the question of whether the presence of pseudohomophone foils (e.g., BRANE) causes homophone effects to be eliminated because of strategic deemphasis of phonological processing. All 6 experiments showed significant homophone effects, which were not eliminated by the presence of pseudohomophone foils. The authors propose that homophone effects in lexical decision are due to the nature of feedback from phonology to orthography. 相似文献

We are biased towards thinking that people are telling the truth. Our study represents the first test of how beliefs about the base rate of truths and lies affect this truth bias. Raters were told either 20, 50 or 80% of the speakers would be telling the truth. As the speaker delivered their statement, participants indicated moment by moment whether they thought the speaker was lying or being truthful. At the end of the statement, they made a final lie–truth judgment and indicated their confidence. While viewing the statement, base rate beliefs had an early influence, but as time progressed, all conditions showed a truth bias. In the final judgment at the end of the statement, raters were truth biased when expecting mostly truths but did not show a lie bias when expecting mostly lies. We conclude base rate beliefs have an early influence, but over time, a truth bias dominates. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献
