Four experiments were conducted to explore the correlation between syllable number and visual complexity in the acquisition of novel words. In the first experiment, adult English speakers invented nonsense words as names for random polygons differing in visual complexity. Visually simple polygons received names containing fewer syllables than visually complex polygons did. In addition, analyses of English word-object pairings indicated that a significant correlation between syllable number and visual complexity exists in the English lexicon. In Experiments 2 and 3, adult English speakers matched monosyllabic novel words more often than trisyllabic novel words with visually simple objects, whereas trisyllabic matches were more common for visually complex objects. Experiment 4 replicated these findings with children, indicating that the assumption of a correlation between word and visual complexity exists during the period of intense vocabulary growth. Although the actual correlation between syllable number and visual complexity is small, other posited constraints on word meaning are also limited in strength. However, an increasing number of small, language-specific word-meaning correlations are being uncovered. Given the documented ability of speakers to detect and use these subtle correlations, we argue that a more fruitful approach to word-meaning acquisition would forgo the search for a few broad, powerful word-meaning constraints, and we attempt to uncover individually weak, but perhaps jointly powerful word-meaning correspondences. 相似文献

Ken Gemes 《Erkenntnis》2005,63(1):139-147
Alleged counter-examples deployed in Park (2004) [Erkenntnis 60: 229–240] against the account of selective hypothetico-deductive confirmation offered in Gemes (1998) [Erkenntnis 49: 1–20] are shown to be ineffective. Furthermore, the reservations expressed in Gemes (1998) [ibid] and (1993) [Philosophy of Science 62: 477–487] about hypothetico-deductivism (H-D) are retracted and replaced with the conclusion that H-D is a viable account of confirmation that captures much of the practice of working scientists. However, because it cannot capture cases of inference to the best explanation and cases of the observational confirmation of statistical hypotheses, it is concluded that H-D cannot supply a complete theory of confirmation. 相似文献

The existing literature addressing Religion and Spirituality supports the idea that attending church is positively associated with health outcomes. However, within this literature there has been an impoverished effort to determine whether the Religiously Unaffiliated will report these positive relationships. Using representative data from Ontario (N = 3620), the relationships between Religious/Spiritual variables (Attendance, Prayer/Meditation, and Religiosity) and health outcomes (Happiness, Self-Rated Health, and Satisfaction with Life) were assessed. Results focused on three recurring trends: the Religiously Unaffiliated experienced attending church less positively than Christians; when compared at the highest level of Attendance, the Religiously Unaffiliated were less healthy than Christians; and when only considering the Religiously Unaffiliated, Religious/Spiritual variables were not significant and positive predictors of health outcomes. The discussion focused on the need to delineate between how Christians and the Religiously Unaffiliated experience Religious/Spiritual variables, and the need to stop over-generalizing the positive relationship between Religious/Spiritual variables and health. 相似文献

The first dynamic interactions between hydrogen and the stress-induced reverse transformation have been investigated by performing an unloading test on a Ni–Ti superelastic alloy subjected to hydrogen charging under a constant applied strain in the elastic deformation region of the martensite phase. Upon unloading the specimen, charged with a small amount of hydrogen, no change in the behaviour of the stress-induced reverse transformation is observed in the stress-strain curve, although the behaviour of the stress-induced martensite transformation changes. With increasing amount of hydrogen charging, the critical stress for the reverse transformation markedly decreases. Eventually, for a larger amount of hydrogen charging, the reverse transformation does not occur, i.e. there is no recovery of the superelastic strain. The residual martensite phase on the side surface of the unloaded specimen is confirmed by X-ray diffraction. Upon training before the unloading test, the properties of the reverse transformation slightly recover after ageing in air at room temperature. The present study indicates that to change the behaviour of the reverse transformation a larger amount of hydrogen than that for the martensite transformation is necessary. In addition, it is likely that a substantial amount of hydrogen in solid solution more strongly suppresses the reverse transformation than hydrogen trapped at defects, thereby stabilising the martensite phase. 相似文献

We tested 4 people who claimed to have significantly better than ordinary face recognition ability. Exceptional ability was
confirmed in each case. On two very different tests of face recognition, all 4 experimental subjects performed beyond the
range of control subject performance. They also scored significantly better than average on a perceptual discrimination test
with faces. This effect was larger with upright than with inverted faces, and the 4 subjects showed a larger “inversion effect”
than did control subjects, who in turn showed a larger inversion effect than did developmental prosopagnosics. This result
indicates an association between face recognition ability and the magnitude of the inversion effect. Overall, these “super-recognizers”
are about as good at face recognition and perception as developmental prosopagnosics are bad. Our findings demonstrate the
existence of people with exceptionally good face recognition ability and show that the range of face recognition and face
perception ability is wider than has been previously acknowledged. 相似文献

Intensive (Daily) Behavior Therapy for School Refusal: A Multiple Baseline Case Series 总被引:1,自引:1,他引:0

The following multiple baseline case series examines school refusal behavior in 4 male adolescents. School refusal symptom presentation was ascertained utilizing a functional analysis from the School Refusal Assessment Scale (Kearney, 2002). For the majority of cases, treatment was conducted within a 15-session intensive format over a 3-week period. Treatment elements included cognitive-behavioral therapy with the adolescent, parent training sessions, or a combination of these strategies. Treatment was effective for 3 of 4 cases in the short term. At 3-year follow-up, all 3 of the acute treatment responders had switched to alternative educational programs, although parents rated them as significantly improved and less impaired compared to pretreatment. Obstacles to treatment, and recommendations for program improvement, are discussed. 相似文献

A randomised, double-blind, placebo-controlled, between subjects study design (N=37) was used to investigate the effects of dexamphetamine on explicit new name learning. Participants ingested 10mg of dexamphetamine or placebo daily over 5 consecutive mornings before learning new names for 50 familiar objects plus fillers. The dexamphetamine group recognised and recalled the new names more accurately than the placebo group over the 5 days and 1 month later. Word learning success was not associated with baseline neuropsychological performance, mood, cardiovascular arousal, or sustained attention. These results may have implications for the pharmacological treatment of acquired naming difficulties. 相似文献

The information content of panoramic images I: The rotational errors and the similarity of views in rectangular experimental arenas 总被引:1,自引:0,他引:1
Stürzl W Cheung A Cheng K Zeil J 《Journal of experimental psychology. Animal behavior processes》2008,34(1):1-14
Animals relocating a target corner in a rectangular space often make rotational errors searching not only at the target corner but also at the diagonally opposite corner. The authors tested whether view-based navigation can explain rotational errors by recording panoramic snapshots at regularly spaced locations in a rectangular box. The authors calculated the global image difference between the image at each location and the image recorded at a target location in 1 of the corners, thus creating a 2-dimensional map of image differences. The authors found the most pronounced minima of image differences at the target corner and the diagonally opposite corner--conditions favoring rotational errors. The authors confirmed these results in virtual reality simulations and showed that the relative salience of different visual cues determines whether image differences are dominated by geometry or by features. The geometry of space is thus implicitly contained in panoramic images and does not require explicit computation by a dedicated module. A testable prediction is that animals making rotational errors in rectangular spaces are guided by remembered views. 相似文献

Effects of task performance, helping, voice, and organizational loyalty on performance appraisal ratings 总被引:2,自引:0,他引:2
Despite the fact that several studies have investigated the relationship between organizational citizenship behavior and performance appraisal ratings, the vast majority of these studies have been cross-sectional, correlational investigations conducted in organizational settings that do not allow researchers to establish the causal nature of this relationship. To address this lack of knowledge regarding causality, the authors conducted 2 studies designed to investigate the effects of task performance, helping behavior, voice, and organizational loyalty on performance appraisal evaluations. Findings demonstrated that each of these forms of behavior has significant effects on performance evaluation decisions and suggest that additional attention should be directed at both voice and organizational loyalty as important forms of citizenship behavior aimed at the organization. 相似文献
