直接针对专家记忆优势效应的理论主要有两个,模板理论和限制调节理论。模板理论认为,专家记忆优势效应是由于专家将许多模板存储于长时记忆中;而限制调节理论认为,专家记忆优势效应是由于专家能够抽取与目标关联的限制来建构刺激物。文章以中国象棋为实验材料.对两个理论进行了比较,实验结果否定了限制调节理论。 相似文献

Although researchers have consistently found that neighborhoods matter, relatively little is known about the processes through which neighborhood-level characteristics influence individual outcomes, and whether interventions targeting improving neighborhood characteristics will be beneficial for children. I examine whether relocating from high- to low-poverty neighborhoods affected low-income Black children's exposure to promotive developmental experiences. Participating families voluntarily relocated from high-poverty, minority segregated, inner-city Chicago neighborhoods to mostly White, low-poverty, suburban and Chicago neighborhoods. Data come from retrospective qualitative interviews with 22 Gautreaux One families an average of 15 years after initial relocation, and from interviews with 43 Gautreaux Two families as they relocated into their new communities. I find that children primarily benefited from the institutional versus the social interaction resources in their new neighborhoods. Furthermore, suburban placement was key in facilitating children's access to higher quality resources. 相似文献

We tested whether children show greater internalizing symptoms when their parents are actively abusing alcohol. In an integrative data analysis, we combined observations over ages 2 through 17 from two longitudinal studies of children of alcoholic parents and matched controls recruited from the community. Using a mixed modeling approach, we tested whether children showed elevated mother- and child-reported internalizing symptoms (a) at the same time that parents showed alcohol-related consequences (time-varying effects), (b) if parents showed greater alcohol-related consequences during the study period (proximal effects), and (c) if parents had a lifetime diagnosis of alcoholism that predated the study period (distal effects). No support for time-varying effects was found; proximal effects of mothers' alcohol-related consequences on child-reported internalizing symptoms were found and distal effects of mother and father alcoholism predicted greater internalizing symptoms among children of alcoholic parents. Implications for the time-embedded relations between parent alcoholism and children's internalizing symptoms are discussed. 相似文献

Although bidirectional parent and child influences have been incorporated in theoretical models pertaining to the development of internalizing and externalizing behaviors in youth, studies have historically focused on the socializing influence that parents have on their children. This has left several important research questions unanswered about the nature of bidirectional parent-child relations across development, including how these bidirectional effects are related to different types of child and adolescent psychopathology. The goal of this special section is to examine some longstanding issues regarding the nature of bidirectional parent-child effects across time using a diverse array of longitudinal datasets. The results from these studies emphasize the importance of considering bidirectional effects in developmental psychopathology research, particularly the often overlooked influence that children and adolescents have on their parents' behavior and emotional well-being. Following these empirical articles, an expert in the field provides a scholarly commentary designed to outline the progress that has been made in understanding bidirectional parent-child effects across development as well as to propose fruitful areas for future research. 相似文献

In order to investigate whether the Lidcombe Program effects a short-term reduction of stuttered speech beyond natural recovery, 46 German preschool children were randomly assigned to a wait-contrast group or to an experimental group which received the Lidcombe Program for 16 weeks. The children were between 3;0 and 5;11 years old, their and both of their parents’ native language was German, stuttering onset had been at least 6 months before, and their stuttering frequency was higher than 3% stuttered syllables. Spontaneous speech samples were recorded at home and in the clinic prior to treatment and after 4 months. Compared to the wait-contrast group, the treatment group showed a significantly higher decrease in stuttered syllables in home-measurements (6.9%SS vs. 1.6%SS) and clinic-measurements (6.8%SS vs. 3.6%SS), and the same increase in articulation rate. The program is considered an enrichment of currently applied early stuttering interventions in Germany.
Educational objectives: Readers will discuss and evaluate: (1) the short-term effects of the Lidcombe Program in comparison to natural recovery on stuttering; (2) the impact of the Lidcombe Program on early stuttering in German-speaking preschool children. 相似文献

When will people become ambivalent about politics? One possibility is that the roots of ambivalence lie within the individual, with differences in political knowledge and attitude strength predicting whether a person internalizes the conflicts of politics. Alternately, attitudinal ambivalence could result from structural differences in the way political choices are presented in the wider political environment. We explore the degree to which different environments promote or limit ambivalence using a matching approach in conjunction with a set of multilevel models. We find that campaign environments can induce candidate ambivalence. In presidential elections, campaign efforts promote ambivalence most when competition between partisan campaign efforts is high. In House elections, campaign spending has a direct effect on levels of candidate ambivalence, where a candidate's spending decreases ambivalence about that candidate and increases ambivalence about opponents. 相似文献

Fifty-eight smokers received abstinence-contingent monetary payments for 1 (n = 15) or 14 (n = 43) days. Those who received contingent payments for 14 days also received 0, 1, or 8 experimenter-delivered cigarette puffs on 5 evenings. The relative reinforcing effects of smoking were assessed in a 3-hr session on the final study day, when participants made 20 choices between smoking or money. The reinforcement contingencies exerted robust control over smoking, and programmed smoking lapses produced few discernible effects. These results further illustrate the robust control that reinforcement contingencies can exert over cigarette smoking and suggest that any effects of lapses on the relative reinforcing effects of smoking are modest under conditions involving abstinence-contingent reinforcement contingencies. 相似文献

Male breast cancer is a serious issue that needs to be addressed more fully by the medical and public community. However,
due to a lack of awareness and limited research on the topic, there is a general absence of knowledge concerning the psychological
implications of this disease in men as well as a need for greater understanding of the medical diagnosis and treatment of
male breast carcinoma. Similarly, there still remains a considerable gender difference between the awareness of female breast
cancer and male breast cancer Although breast cancer in men makes up only 1% of all breast cancers reported in the United
States, it is increasing in incidence. There are approximately 2000 new cases and approximately 450 deaths due to male breast
cancer each year. Breast cancer diagnosis and treatment in men is very similar to that described in women, however, it has
been shown that men are being diagnosed at a later stage of the disease than women. 相似文献

Masked priming has been employed to study the role of consciousness for different levels of visual processing. However, masking procedures differ systematically between studies. To examine these procedural differences we contrasted priming effects with metacontrast masking, which is often applied in the context of perceptual priming, and priming effects with sandwich pattern masking, frequently used in studies on semantic priming. Results indicate that the amount of masking neither affects perceptual nor semantic priming effects in a semantic categorization task when a metacontrast masking paradigm was used. However, perceptual and semantic priming effects increased with increasing prime visibility when a sandwich pattern masking paradigm was used. Findings suggest that different types of masking procedures affect the processing of the masked stimuli in substantially different ways even if the masking effect on conscious perception of these stimuli is comparable. 相似文献
