This study examined the ability of prior academic performance, proxy efficacy, and academic self-efficacy to predict college academic performance. Participants ( N = 202) completed a modified version of the Teacher Collective Efficacy scale ( Goddard, 2001 ), the Academic Self-Efficacy scale ( Elias & Loomis, 2000 ), and a demographic questionnaire. Prior performance was predictive of both academic self-efficacy beliefs and college performance. Hierarchical regression analysis indicates that academic self-efficacy beliefs explain a significant amount of unique variance beyond past performance in predicting college performance. Proxy efficacy did serve as a predictor of student academic self-efficacy, but did not serve as a predictor of college performance. Implications for instructors, as well as for future research, are discussed. 相似文献

This study examined the relative involvement of rapid auditory and visual temporal resolution mechanisms in the reading of phonologically regular pseudowords and English irregular words presented both in isolation and in contiguity as a series of six words. Seventy-nine undergraduates participated in a range of reading, visual temporal, and auditory temporal tasks. The correlation analyses suggested a general timing mechanism across modalities. There were more significant correlations between the visual temporal measures and irregular word reading and between the auditory measures and pseudoword reading. Auditory gap detection predicted pseudoword reading accuracies. The low temporal frequency flicker contrast sensitivity measure predicted the accuracies of isolated irregular words and pseudowords presented in contiguity. However, when a combined speed-accuracy score was used, visible persistence at both low and high spatial frequencies and auditory gap detection were active in the reading of pseudowords presented in contiguity. Sensory processing skills in both visual and auditory modalities accounted for some of the variance in the reading performance of normal undergraduates, not just reading-impaired students. 相似文献

A key assumption in language comprehension is that biases in behavioral data, such as the tendency to interpretJohn said that Mary left yesterday to mean thatyesterday modifies the syntactically local verb left, not the distant verbsaid, reflect inherent biases in the language comprehension system. In the present article, an alternative production-distribution-comprehension
(PDC) account is pursued; this account states that comprehension biases emerge from different interpretation frequencies in
the language, which themselves emerge from pressures on the language production system to produce some structures more than
others. In two corpus analyses and two self-paced reading experiments, we investigated these claims for verb modification
ambiguities, for which phrase length is hypothesized to shape production. The results support claims that tendencies to produce
short phrases before long ones create distributional regularities for modification ambiguities in the language and that learning
over these regularities shapes comprehenders’ interpretations of modification ambiguities. Implications for the PDC and other
accounts are discussed. 相似文献

The literature on pain and aggression has indicated that pain elicits aggression. However, research has generally examined pain as a situational variable and focused less on the dispositional ability of an individual to tolerate pain. The dearth of research on pain tolerance and aggression appears to contradict the existing theory on the aggression‐eliciting effect of pain, in that studies have found a positive relationship between pain tolerance and aggression. The purpose of this study was to determine whether the relationship between pain tolerance and aggression is moderated by sex and whether the positive relationship could be explained by masculine gender role conformity. A sample of 195 collegiate men and women completed trait measures and a laboratory assessment of pain tolerance. Results indicated that correlations between pain tolerance and trait aggression were significant and positive for men but not women. However, when men's conformity to masculine gender role was controlled for, the relationship between pain tolerance and trait aggression was nil and nonsignificant. Results are discussed in reference to socialization and maintenance of masculine status. Aggr. Behav. 35:422–429, 2009. © 2009 Wiley‐Liss, Inc. 相似文献

This study assessed engaged lifestyle activities (e.g., volunteering, traveling, and public speaking) for centenarians of
the Georgia Centenarian Study. A total of 285 centenarians and near-centenarians (i.e., 98 years and older) and their proxy
informants participated in this study. The Mini-Mental Status Examination (MMSE) was assessed for all centenarians, and proxy
informants reported on lifestyle activities and personality traits of the centenarians. Results suggested that participants
who had volunteered, traveled, and those who had given public talks and balanced their checkbooks were more likely to show
relatively high mental status scores (i.e., MMSE > 17). Personality traits were found to be moderators in the relationship
between engaged lifestyle and mental status: Participants with high levels of Emotional Stability, Extraversion, Openness,
and Conscientiousness and with high levels of engaged lifestyle were more likely to show relatively high mental status scores
(i.e., MMSE > 17), whereas participants with low levels of Emotional Stability, Extraversion, Openness, Agreeableness, and
Conscientiousness and with low levels of engaged lifestyle were more likely to show relatively low mental status scores (i.e.,
MMSE < 18). The results suggest that engaged lifestyle, particularly in combination with personality traits, plays an important
role in the level of cognitive functioning among oldest old adults. 相似文献

We report an empirical study on leaf-carrying, a newly discovered nest-building technique that involves collecting nest materials
before reaching the nest site. We assessed whether leaf-carrying by rehabilitant orangutans on Kaja Island, Central Kalimantan,
owes to cultural influences. Findings derive from ca 600 h observational data on nesting skills and nesting associations in
Kaja’s 42 resident rehabilitants, which yielded 355 nests and 125 leaf-carrying cases by 34 rehabilitants. Regional contrasts
with 14 other communities (7 rehabilitant, 7 wild) indicated cultural influences on leaf-carrying on Kaja. Association data
showed exceptional social learning opportunities for leaf-carrying on Kaja, with residents taking differential advantage of
these opportunities as a function of development, experience, and social position. Juvenile males with basic nesting skills
were most influenced by social input. Most (27) leaf-carriers had probably learned leaf-carrying when caged and 7 probably
learned it on Kaja. Social priming was probably the main impetus to leaf-carrying on Kaja, by simply prompting observers to
copy when leaf-carrying associates collected nesting materials, what they collected, and where they used their collected materials. Implications concern acquisition processes and ontogenetic schedules that orchestrate
sets of features—needs or interests, cognitive abilities, social preferences—which enable cultural transmission. 相似文献

Empirical investigations of humans, pigeons, rats, and monkeys have indicated that these species will select free over forced choice, even when faced with identical outcomes. However, the same has yet to be quantitatively confirmed in nonhuman great apes. This experiment is the first systematic investigation of preference for free or forced choice in great apes using a paradigm in which extraneous variables are highly controlled. Three orangutans were given a choice of one of two virtual routes, one that provided a choice and one that did not via a touchscreen computer program. Choice of either route was rewarded with the same type and quantity of food. Initial results indicated a preference for free choice across all three participants. However, in two control conditions, orangutans' preferences varied, suggesting a weaker tendency to exercise choice than species previously tested. We suggest further investigation of preference for free and forced choice in orangutans and other great apes through alternative experimental paradigms that focus on increasing the fidelity of free and forced choice options. 相似文献

Changes in activation levels with negation 总被引:3,自引:0,他引:3

Three experiments investigated the effects of negation during on-line language processing. It was hypothesized that negation of a noun (e.g., no bread) would affect the activation level of the mental representation of that noun. Experiment 1 manipulated the location of the negation in sentences that were followed by a probe recognition task. Subjects were slower to indicate that a probe had been in the sentence when the probe corresponded to a negated noun. Experiment 2 replicated these results with a probe naming task. Experiment 3 replicated the result that reading the phrase no bread inhibits responses to bread in the probe task but found no evidence of inhibition of the response to an associate probe, such as butter. The results of these three studies suggest that negation affects the discourse focus of a noun phrase, and hence the activation level of its representation. 相似文献
