The authors examined the associations that underlie the orientations of bilingual Latino college students toward family and school. Participants completed, in English or Spanish, 3 implicit association tests assessing their attitude toward family vs. school, identifications with these concepts, and self-esteem. Results revealed a more positive attitude toward, and stronger identification with, family than school. Identification with family was stronger among participants who completed the study in English, suggesting self-definition in terms of distinctions from the context. Last, the more participants valued family over school and identified with family rather than school, the higher was their self-esteem. These findings shed light on the subtle, yet crucial, mechanisms by which cultural knowledge is incorporated in the self-concept of bilingual Latino college students. 相似文献

The purpose of this study was to use cluster analysis to identify differences in goal orientation and motivational climate profiles among students in physical education classes as well as differences among the observed clusters on perceived flow experiences. 983 students of 14- to 15-yr.-olds (M = 14.8 yr., SD = 0.91) from a large Spanish metropolitan school district were participants and completed questionnaires assessing goal orientations, motivational climates, and perceived flow. Analysis showed three distinct clusters with 40.3% of the sample with a High Motivation cluster, 27.6% in a Low Motivation cluster, and 32.2% in a Mastery Motivation cluster. These three clusters differed significantly in ratings of perceived flow. Clusters also showed different composition by sex. Implications of these results with regard to instruction in physical education classes are discussed. 相似文献

This investigation examined the effects of distributed and massed practice on the learning and retention of a discrete computerized skill (Exp. 1) and a continuous computerized skill (Exp. 2). 40 men were randomly assigned to one of four groups, of which two groups took part in Exp. 1 and two groups in Exp. 2. Performance was assessed at various points during acquisition and then on 8 retention tests conducted at varying times after acquisition. Learning curves for practice were highly similar for the two conditions. Participants in the distributed-practice group performed significantly better than those in the massed-practice group at the end of practice on both the discrete and continuous skills. However, participants in the distributed-practice group performed significantly more poorly on retention during 24 hr. and after acquisition. Participants in the massed-practice condition performed significantly better on retention tests than did those who learned in the distributed-practice condition. 相似文献

This paper analyzes the sum score based (SSB) formulation of the Rasch model, where items and sum scores of persons are considered
as factors in a logit model. After reviewing the evolution leading to the equality between their maximum likelihood estimates,
the SSB model is then discussed from the point of view of pseudo-likelihood and of misspecified models. This is then employed
to provide new insights into the origin of the known inconsistency of the difficulty parameter estimates in the Rasch model.
The main results consist of exact relationships between the estimated standard errors for both models; and, for the ability
parameters, an upper bound for the estimated standard errors of the Rasch model in terms of those for the SSB model, which
are more easily available.

Vigilance or scanning involves interruptions in foraging behavior when individuals lift their heads and conduct visual monitoring of the environment. Theoretical considerations assume that foraging with the "head down", and scanning ("head up") are mutually exclusive activities, such that foraging precludes vigilance. We tested this generalization in a socially foraging, small mammal model, the diurnal Chilean degu (Octodon degus). We studied spontaneous bouts of scanning of captive degus when foraging in pairs of female sibs and non-sibs. We examined the extent to which foraging (head down postures) and scanning (head up postures) were mutually exclusive in subjects exposed to none, partial, and complete lateral visual obstruction of their partners. In addition, we monitored the orientation of their bodies to examine the target of attention while foraging and scanning. Lastly, we examined the temporal occurrence of scanning events to assess the extent of scanning coordination, and whether this coordination is kin-biased. Visual obstruction had a significant influence on degu vigilance. Focal degus increased their quadrupedal and semi-erect scanning when foraging under a partially obstructed view of their partners. Degus oriented their bodies toward partners when foraging and scanning. Despite this, degus did not coordinate scanning bouts; instead, they scanned independently from one another. Relatedness among cage mates did not influence any aspect of degu behavior. Contrary to theoretical expectations, these results indicate that foraging and vigilance are not mutually exclusive, and that kinship per se does not influence scanning behavior and coordination. 相似文献

This article reports an effectiveness case study of the individual systemic therapy of a 22‐year‐old Portuguese woman with a diagnosis of paranoid personality disorder, conducted in a university‐based clinic in Lisbon, Portugal. Data were analysed using the hermeneutic single‐case efficacy design, a non‐experimental interpretive approach that aims to determine whether change occurred, whether change was due to therapeutic strategies, and what in therapy caused the change. Results indicate that the treatment was effective and that de‐pathologising Pamina's condition and genogram‐based exploration techniques played a crucial role in her recovery. 相似文献

副中央凹预视效应指当读者正注视某个词(即位于中央凹的词n)时, 可以获得词n右侧词(即位于副中央凹词n+1或词n+2)的部分信息。在阅读过程中读者能否从副中央凹预视到信息, 会直接影响他们的阅读效率。因此, 探讨阅读过程中的副中央凹预视效应产生的条件、影响因素及机制, 成为阅读心理学需要解决的基本问题之一。本文系统总结了中外文阅读过程中副中央凹预视效应的研究进展, 包括副中央凹预视效应的研究范式, 中外文阅读过程中副中央凹预视的信息类型、不同类型信息预视加工的时间进程, 以及空间上获得预视信息的范围。最后提出中文阅读过程中副中央凹预视研究需要解决的几个关键问题。 相似文献

A quantitative analysis of broadcasted violence by the main television (TV) channels transmitting for Madrid (Spain) was carried out using a novel method that randomly selects fragments of delimited duration from TV broadcasts. The device selects acts of aggression shown in those TV extracts, and classifies them according to their type. There was a high incidence of aggressive acts, especially physical (particularly leading to death), in TV fiction: films, serials and promos. The device also allowed examination of the prominence of aggression in children's programs, as well as showing minimal variation in the number of aggressive acts over screened time intervals. The pattern of the collected data suggests that the broadcasting of violence on TV emphasizes the conflicting elements of social reality, reproducing it in fiction, news reports and children's shows.

Mind–body dualism has rarely been an issue in the generative study of mind; Chomsky himself has long claimed it to be incoherent
and unformulable. We first present and defend this negative argument but then suggest that the generative enterprise may license
a rather novel and internalist view of the mind and its place in nature, different from all of, (i) the commonly assumed functionalist
metaphysics of generative linguistics, (ii) physicalism, and (iii) Chomsky’s negative stance. Our argument departs from the
empirical observation that the linguistic mind gives rise to hierarchies of semantic complexity that we argue (only) follow
from constraints of an essentially mathematical kind. We assume that the faculty of language tightly correlates with the mathematical
capacity both formally and in evolution, the latter plausibly arising as an abstraction from the former, as a kind of specialized
output. On this basis, and since the semantic hierarchies in question are mirrored in the syntactic complexity of the expression
involved, we posit the existence of a higher-dimensional syntax structured on the model of the hierarchy of numbers, in order
to explain the semantic facts in question. If so, syntax does not have a physicalist interpretation any more than the hierarchy
of number-theoretic spaces does. 相似文献
