In 2 experiments, the authors explored age of acquisition (AoA) and word frequency (WF) effects in picture naming using the psychological refractory period paradigm. In Experiment 1, participants named a picture and then, a short time later, categorized 1 of 3 possible auditory tones as high, medium, or low. Both AoA (Experiment 1A) and WF (Experiment 1B) effects propagated onto tone discrimination reaction times (RTs), with the effects of AoA being stronger. In Experiment 2, the to-be-named picture followed the auditory tone by a varying interval. As the interval decreased, picture naming RTs increased. The relationship between the interval and AoA (Experiment 2A) was reliably underadditive; AoA effects were eliminated at the shortest interval. In contrast, WF (Experiment 2B) was additive with the effects of the interval. These results demonstrate an empirical dissociation between AoA and WF effects. AoA affects processing stages that precede those that are sensitive to WF. The implications for theories of picture naming are discussed.  相似文献

To investigate how the culturalist perspective on investigating racial group differences in standardized cognitive ability tests has advanced, a content analysis of 28 studies citing J. E. Helms (1992) identified 7 general themes. Overall, researchers cited J. E. Helms (1992) as support for their own hypotheses but did not directly test the culturalist perspective. Para investigar cómo ha avanzado la perspectiva culturalista sobre la investigación de las diferencias entre grupos raciales en los tests estandarizados de abilidades cognitivas, un análisis de contenido de 28 estudios que citan a J. E. Helms (1992) identificó 7 temas generales. En conjunto, los investigadores citaron a J. E. Helms (1992) para apoyar sus propias hipótesis, pero no comprobaron la perspectiva culturalista directamente.  相似文献

Companies and organizations use integrity tests to screen job applicants, and the fakability of these tests remains a concern. The present study uses two separate designs to analyze the fakability of the Personnel Reaction Blank (PRB) and the personality constructs related to integrity test scores. The results demonstrate that the PRB can be successfully faked. Moreover, a within-participants design resulted in significantly greater faking than the between-participants design. The personality constructs conscientiousness, agreeableness, and neuroticism were significantly correlated with honest scores on the PRB, and there was a significant negative correlation between conscientiousness and magnitude of faking.

Conventional wisdom in much of the educational and psychological literatures states that the ethnic and racial identity of African American students is related to their academic achievement. The purpose of this study was to determine whether ethnic identity and anti-white attitudes predicted the academic achievement of African American students at a historically Black university. A hypothesized path model was proposed that included ethnic identity, attitudes toward other ethnic groups, anti-white attitudes, perceptions of caring faculty, academic self-concept, and devaluing academic success. The path analysis model explained 27% of the variance in grade point average and revealed three direct effects on grade point average: (a) academic self-concept (positive), (b) devaluing academic success (negative), and (c) anti-white attitudes (negative). Ethnic identity was indirectly linked with grade point average (GPA) through academic self-concept and devaluing academic success. Tests of two alternative nested models suggest that even in an indirect role, ethnic identity may be more important than anti-white attitudes in a model of African American academic achievement.

A number of studies have evaluated counselling interventions for people with myalgic encephalitis, but few report client perceptions in any detail. This study seeks to explore client perceptions using a qualitative methodology. A sample of 25 individuals with myalgic encephalitis were interviewed about their experiences in counselling. The interviews were transcribed and subjected to thematic analysis using grounded theory principles. The analysis showed that people with myalgic encephalitis endure significant changes to their lives, often involving great loss and trauma. After seeking help through counselling, participants had experienced a wide variety of approaches and there were positive and negative perceptions of each. Other perceptions related to therapist characteristics and the way in which interventions were carried out. Recommendations for practitioners are given.  相似文献

Schizophrenia     
ABSTRACT— Theoretical conceptualizations of schizophrenia have undergone significant change in the past century. Through the application of behavioral science methodology, psychologists have played a major role in the pivotal scientific advances that have led us to contemporary models. The field has moved from simplistic conceptualizations of mind–brain distinctions to models that encompass complex gene–environment interactions and neural pathways that mediate the relation between psychosocial events and brain dysfunction.  相似文献

We investigated the processing of sentences containing a quantifier scope ambiguity, such as Kelly showed a photo to each critic, which is ambiguous between the indefinite phrase (a photo) having one or many referents. Ambiguity resolution requires the computation of relative quantifier scope, with either a photo or each critic taking wide scope, thereby determining the number of referents. Using eye tracking, we established that multiple factors, including the grammatical function and surface linear order of quantified phrases, along with their lexical characteristics, interact during the processing of relative quantifier scope, with conflict between factors incurring a processing cost. We discuss the results in terms of theoretical accounts attributing sentence-processing difficulty to either reanalysis (e.g., Fodor, 1982) or competition between rival analyses (e.g., Kurtzman & MacDonald, 1993).  相似文献

An intervention study was conducted to investigate whether advanced ego development could be promoted if account was taken of the factors likely to be involved in the ego stage transition process in adulthood. A conceptual framework that identified such factors was described, in which it was hypothesised that stage transition occurs in response to life experiences that are structurally disequilibrating, personally salient, emotionally engaging, and interpersonal. The intervention was designed in accordance with these proposed types of life experiences, and was targeted toward adults at the modal stage of ego development. Using an experimental design, a significant increase in ego level was found in 2 equivalent intervention groups, with no increase found in a matched control group. The findings demonstrate the possibility of continued ego development in adulthood, including development to the advanced ego stages, and provide clarification regarding some of the processes involved in such development.  相似文献

Exposure to inescapable stressors enhances cue-dependent learning in male rats; enhanced learning is apparent as facilitated acquisition of the classically conditioned eyeblink respouse (CCER). The proinflammatory cytokines, in particular interleukin (IL)-1beta, are presumed to orchestrate a number of acute-phase stress responses in rats, most notably fever, reduced feeding, and inactivity. Little is known of the impact proinflammatory cytokines have on learning and memory processes. Here, we address the effects of IL-1beta treatment on acquisition of the classically conditioned eyeblink response 2 hours [?] after injection in male rats. Training was accomplished with a delay-type paradigm (500-ms conditional stimulus coterminating with a 10-ms periorbital unconditional stimulation). Facilitated acquisition was clearly apparent in rats treated with IL-1beta (3.0 microg/kg). In a second experiment, we compared rats treated with 3.0 microg/kg to those treated with 1.0 microg/kg. Facilitated acquisition was reproduced, but the lower dose did not appreciably affect acquisition. These data further support contentions that IL-1beta has anxiogenic properties, affecting basic new motor learning in a manner similar to that observed after exposure to stress.  相似文献
