Language development is characterized by predictable shifts in the words children produce and the complexity of their utterances. Because acquisition typically occurs simultaneously with maturation and cognitive development, it is difficult to determine the causes of these shifts. We explored how acquisition proceeds in the absence of possible cognitive or maturational roadblocks, by examining the acquisition of English in internationally adopted preschoolers. Like infants, and unlike other second-language learners, these children acquire language from child-directed speech, without access to bilingual informants. Parental reports and speech samples were collected from 27 preschoolers, 3 to 18 months after they were adopted from China. These children showed the same developmental patterns in language production as monolingual infants (matched for vocabulary size). Early on, their vocabularies were dominated by nouns, their utterances were short, and grammatical morphemes were generally omitted. Children at later stages had more diverse vocabularies and produced longer utterances with more grammatical morphemes.  相似文献

Recent scholars have dismissed the utility of self-esteem as well as programs designed to improve it. The authors challenge these contentions on conceptual, methodological, and empirical grounds. They begin by proposing that the scope of recent analyses has been overly narrow and should be broadened to include specific as well as global self-views. Using this conceptualization, the authors place recent critiques in historical context, recalling that similarly skeptical commentaries on global attitudes and traits inspired theorizing and empirical research that subsequently restored faith in the value of both constructs. Specifically, they point to 3 strategies for attaining more optimistic assessments of the predictive validity of self-views: recognizing the utility of incorporating additional variables in predictive schemes, matching the specificity of predictors and criteria, and using theoretically informed standards for evaluating predictor- criterion relationships. The authors conclude that self-views do matter and that it is worthwhile and important to develop and implement theoretically informed programs to improve them.  相似文献

A bicycle helmet program was evaluated in three middle schools using a multiple baseline across schools design. Two of the three schools had histories of enforcement of helmet use. During baseline many students riding their bikes to and from school did not wear their helmets or wore them incorrectly. A program that consisted of peer data collection of correct helmet use, education on how to wear a bicycle helmet correctly, peer goal setting, public posting of the percentage of correct helmet use, and shared reinforcers, all of which were implemented by the school resource officer, increased afternoon helmet use and afternoon correct helmet use in all three schools. Probe data collected a distance from all three schools indicated that students did not remove their helmets once they were no longer in close proximity to the school, and probe data collected in the morning at two of the schools showed that the behavior change transferred to the morning.  相似文献

The purpose of this study was to examine the role of adolescent IQ (AIQ) and gender in older adults' ability to use cognitive support to enhance memory. Subjects were 269 mid-1940s graduates of the same high school. Adolescent IQ scores were gathered from archives, and subjects' memory for words was tested with tasks that provided increasing cognitive support. Overall, subjects benefited from support; women recalled more words than men; and persons with a high AIQ remembered more words than persons with a lower AIQ. However, while all subjects showed gains from cognitive support, men with a lower AIQ performed worse than men with a high AIQ. Women's performance was not dependent on their AIQ. Analysis of qualitative memory indicators suggested that women and persons with a high AIQ had better encoding and retrieval operations. Men with a lower AIQ appear to be particularly vulnerable to memory deficits in aging. This may be due to low "cognitive reserve" or generally poorer episodic memory function.  相似文献

Sending young children to boarding school may be considered a particularly British form of child abuse and social control. The trauma of the rupture with home may be followed by other ordeals such as emotional deprivation and, in extreme cases, physical and sexual abuse. The taboo on expressing emotion, which is common in such institutions, may lead to an encapsulation of the self. Consequently, the needs of the distressed child/self remain active, but unconscious, within the adult. This maybe disguised by an armoured, and very often socially successful, persona. The psychological interplay, between these two facets of the personality, may be detrimental to intimate relationships. In clinical practice the emotional conflict between a desire for intimacy and anticipated exile comes to the fore. Three examples demonstrate how within the transference this may lead to a dependent and erotic atmosphere, which abruptly changes to sever all connection. Changes in the frame, breaks in analysis, and confessions of emotional need are all points at which vigilance is required if such disturbance in analysis is not to end in its abrupt termination.  相似文献

Dizziness is commonly associated with anxiety, and is often caused by a dysfunction of the balance system. While a link between dizziness and both anxiety disorders and depression has been established, less is known about information processing in dizziness. In the first experiment we tested whether 15 patients with dizziness would display an emotional Stroop effect for panic-related words. Also included was a control group of 15 persons. The Stroop task was preceded by ratings of personal relevance of the Stroop words and followed by a surprise free recall of the words. Results showed a Stroop effect for panic-related words in the dizziness group, but the interaction did not reach significance (p = 0.08). Separate analysis of dizziness-related panic words however resulted in a significant group x condition interaction. In the free recall of Stroop words a main effect of word category was found, with more panic-related words being recalled. The second experiment investigated autobiographical memories in 14 patients with dizziness and 14 matched controls. Results showed a group x condition interaction with less specific memories being recalled following positive cue-words in the dizziness group. The overall pattern of results suggests that dizziness is related to deficits in information processing, which could be targeted in treatment.  相似文献

The precarious couple effect occurs when men pair with women who are both critical and more verbally disinhibited than them. Evidence that dissatisfaction runs high in such relationships makes one ask why people enter them in the first place. In Study 1, respondents recalled that past partners who were verbally disinhibited were relatively active in initiating the relationship. In Study 2, verbally inhibited men evidenced ambivalence in that they disliked disinhibited women more than inhibited ones but these feelings of disliking did not translate into expectations of feeling tense during the interaction. Study 3 revealed that initial interactions between inhibited men and disinhibited women go smoothly unless (a) the women are critical and (b) the pair discusses a stressful topic. The authors suggest that members of precarious couples are drawn to one another because, in initial encounters, their communication styles are relatively symbiotic. Alas, this initial chemistry does not always endure.  相似文献

Limited information exists on the racial attitudes and ethnic identities of groups of mixed racial origin. The present research tested the hypotheses that the construct of ethnic identity is valid among such groups and that ethnic identity is related to out-group prejudice, as predicted by social identity theory. The Multigroup Ethnic Identity Measure, the Anti-White Scale, and the Subtle Racism Scale were administered to 70 South Africans of mixed racial descent, the so-called Coloureds. A factor analysis supported the structural validity of the 12-item measure of ethnic identity with this sample, but correlations between scales did not support the prediction that group identity would be positively associated with out-group prejudice. Group identity was positively related .27 to positive attitudes toward Whites consistent with the tenets of social dominance theory.  相似文献

The purpose of this paper is to review research on the prevalence of children's exposure to domestic violence, to consider the available literature on the co-occurrence of domestic violence and child maltreatment, and to gain more understanding about the impact of exposure on children. There is clear evidence indicating that both severe and moderate violence occurs frequently in homes among family members and that children are exposed to this violence. However, because of differing definitions of what constitutes domestic violence and variability in research methodologies for collecting the data, there are significant discrepancies in prevalence reports across studies. Of great concern is the immediate impact on the children and the long-term consequences for their later relationships. Fewer studies have been done on the co-occurrence of domestic violence and child maltreatment. However, it is likely that children who live in homes where domestic violence occurs are more likely to be abused and neglected. On the basis of available research, there is little doubt that vast numbers of children are exposed to domestic violence and that children's responses vary widely depending on their risk and vulnerability, as well as the structure of their environments. A developmental risk and protective factors framework will be used to integrate the information on children's exposure to violence.  相似文献

The negative effects of false information presented either prior to (proactive interference; PI) or following (retroactive interference; RI) true information was examined with word definitions (Experiment 1) and trivia facts (Experiment 2). Participants were explicitly aware of which information was true and false when shown, and true-false discrimination was evaluated via multiple-choice tests. Negative suggestion, defined as poorer performance on interference items than noninterference (control) items, consistently occurred when the wrong information followed the correct information (RI) but not when it preceded the correct information (PI). These effects did not change as a function of retention interval (immediate, 1 week, or 3 weeks) or number of incorrect alternatives (1 or 3). Implications of this outcome for experiencing incorrect information in both academic and nonacademic situations are considered.  相似文献
