We review empirical findings from children with primary or "specific" language impairment (PLI) and children who learn a single language from birth (L1) and a second language (L2) beginning in childhood. The PLI profile is presented in terms of both language and nonlinguistic features. The discussion of L2 learners emphasizes variable patterns of growth and skill distribution in L1 and L2 which complicate the identification of PLI in linguistically diverse learners. We then introduce our research program, designed to map out common ground and potential fault lines between typically developing children learning one or two languages, as compared to children with PLI. 相似文献

A theoretically based, culture-fair test of new learning ability is predictive of academic achievement. A sample of 633 adults, 121 of minority status, drawn from urban private universities, colleges, and community colleges were given information as to the meanings of previously unknown words, sayings, similarities, and analogies. They were also tested for their existing knowledge of vocabulary, opposites, and analogies with a brief version of the Scholastic Assessment Test (SAT). New learning ability proved to be culture-fair, reliable, and predictive of grades and of the brief version of the SAT. 相似文献

Over the past three decades, research on the social dimensions of emotions has grown exponentially, particularly in the area
of “emotion management.” In this project, we will attempt to add to this body of research by studying the social aspects of
labeling or “instantiating” feelings. The data for the project come from televised red-carpet interviews conducted with celebrities
immediately prior to awards ceremonies. By focusing on the generic aspects of the emotional claims-making put forth by interviewers
and interviewees, we demonstrate how the labeling of emotions is an interpretive, interactive task.

Prejudice against overweight people is rife. However, there is a paucity of research on the underlying reasons for it. In two studies the relationship between body image, the tendency to make physical appearance-related comparisons (PACS), and both explicit and implicit anti-fat attitudes was examined. In Study 1 (n = 227) people with a high tendency to make physical appearance-related comparisons (high PACS scorers) reported lower self-appearance evaluation, but higher appearance orientation and explicit anti-fat attitudes. The PACS fully mediated the relationship between appearance orientation and explicit anti-fat attitudes. Study 2 (n = 134) found that the PACS also mediated the relationship between appearance orientation and implicit anti-fat attitudes. Thus, individual differences in factors such as body image and the tendency to make appearance-related comparisons, appear to play a central role in both explicit and implicit anti-fat attitudes. 相似文献

Pigeons were trained to match the number of responses made during a production phase to the number of keylight flashes (2, 4, or 6) in a previous sample phase. In Experiment 1, there were 2 conditions in which the flashes were programmed to occur at a constant rate or within a constant overall duration. For both conditions, although accuracy was relatively low, responding increased linearly with flash number and coefficients of variation decreased. Positive transfer to novel numbers was obtained only when test and baseline trials had the same temporal organization, but multiple regressions revealed significant control by number independently of temporal cues. In Experiment 2, flashes were programmed to occur pseudorandomly to degrade the validity of temporal cues. Results were similar to in Experiment 1. A prototype response class model accounted for the major features of the data. According to the model, responses during the production phase are shaped into higher order units that are associated with different stimulus numbers and function as a rough category scale of numerosity. 相似文献

Persistent symptoms of nausea, distress, and vomiting triggered by reminders of cancer treatment were examined among 273 Hodgkin's disease survivors, 1 to 20 years posttreatment. Prevalence rates were high for distress and nausea but low for vomiting. Retrospective report of anticipatory symptoms during treatment was the strongest predictor of persistent symptoms, suggesting that treatment-induced symptoms are less likely to persist if conditioning does not occur initially. Time since treatment was also a significant predictor, with patients more recently treated more likely to experience persistent symptoms. Thus, an explanatory model based on classical conditioning theory successfully predicted presence of persistent symptoms. Symptoms also were associated with ongoing psychological distress, suggesting that quality of life is diminished among survivors with persistent symptoms. Recommendations for prevention and treatment of symptoms are discussed. 相似文献

I argue that we need not accept Quine's holistic conception of mathematics and empirical science. Specifically, I argue that we should reject Quine's holism for two reasons. One, his argument for this position fails to appreciate that the revision of the mathematics employed in scientific theories is often related to an expansion of the possibilities of describing the empirical world, and that this reveals that mathematics serves as a kind of rational framework for empirical theorizing. Two, this holistic conception does not clearly demarcate pure mathematics from applied mathematics. In arguing against Quine, I present a formal account of applied mathematics in which the mathematics employed in an empirical theory plays a role that is analogous to the epistemological role Kant assigned synthetic a priori propositions. According to this account, it is possible to insulate pure mathematics from empirical falsification, and there is a sense in which applied mathematics can also be labeled as a priori.I am especially indebted to Michael Friedman for his valuable suggestions and criticisms of this paper. I would also like to thank Mark Wilson, Anil Gupta, and Arthur Fine for their comments and encouragement. 相似文献

Inevitable declines in sensory abilities may put older drivers and pedestrians at risk unless they become aware of these changes and can safeguard themselves by modifying their behaviour. A questionnaire designed to evaluate older people's awareness of their sensory abilities with regard to road use was administered to 80 individuals aged from 50 to 79 years, who were also given eyesight and hearing tests. Despite marked declines in their objective sensory efficiency, people in their 70s did not rate their sensory abilities as poor any more than did people in their 50s. Individuals of any age who did subjectively perceive declines in their sensory abilities also reported that they had made very sensible adjustments in their road-use behaviour, for example, avoiding complex junctions. Those individuals who reported taking such precautions also reported fewer recent accidents. One month after completing the questionnaire, and being given the results of their eyesight and hearing tests, two-thirds of individuals reported that they had made important changes in their behaviour on the roads. Many now avoided or took particular care in dangerous situations, and some had started to wear prescribed spectacles more appropriately. The implications of older people's lack of awareness of changes in their sensory abilities to their safety on the roads, and in general, are discussed. Factors causing the age-related mismatch between actual and subjectively perceived sensory abilities are discussed. 相似文献

Perception of voicing for stop consonants in consonant-vowel syllables can be affected by the duration of the following vowel so that longer vowels lead to more “voiced” responses. On the basis of several experiments, Green, Stevens, and Kuhl (1994) concluded that continuity of fundamental frequency (f0), but not continuity of formant structure, determined the effective length of the following vowel. In an extension of those efforts, we found here that both effects were critically dependent on particular f 0s and formant values. First, discontinuity inf0 does not necessarily preclude the vowel length effect because the effect maintains whenf0 changes from 200 to 100 Hz, and 200-Hz partials extend continuously through test syllables. Second, spectral discontinuity does preclude the vowel length effect when formant changes result in a spectral peak shifting to another harmonic. The results indicate that the effectiveness of stimulus changes for sustaining or diminishing the vowel length effect depends critically on particulars of spectral composition. 相似文献
