Conflicting findings with respect to the effects of experimental manipulations on priming have been reported in previous studies. It is argued that, in many priming tasks, large amounts of task-relevant information are available from various sources, and that, therefore, the information available from a specific study episode will have only a small impact on overall performance level. Under such circumstances, high levels of baseline performance and small priming effects will be observed. The experiments reported here investigated the hypothesis that a high baseline performance in informationprocessing tasks that are used to measure priming may constrain priming effects. In a series of wordnaming experiments, perceptual difficulty and, therefore, baseline performance was manipulated. Under easy conditions, priming effects were relatively small and were not affected by word frequency, spaced repetition, or delay. Under more difficult conditions, priming effects were larger, and significant effects of all of the above-mentioned experimental manipulations were observed. Under conditions that produced the largest priming effects, a significant relationship between priming and explicit-memory performance could be observed. In the last experiment, it was shown that the characteristics of the retrieval task can substantially affect the magnitude of priming. It is argued that priming effects should be considered to reflect interactions between memory traces and the information-processing components of the priming task. 相似文献

A comprehensive research project on smoking among Norwegian schoolchildren was started in 1975. Results from two nation-wide questionnaire surveys and from two field experiments were presented. The first field experiment (1978) demonstrated that different approaches to smoking and health education had different effects on the pupils' reported tobacco consumption. In three of four experimental groups, the reported short-term reduction of cigarettes smoked was statistically significant. If the pupils were actively involved, and when their parents were involved, the reported reduction of cigarettes smoked was 21 % compared to only 6% in a group with passive pupils and no involvement of the parents. In a second field experiment (1979-80), a long-term reduction was shown. During the first six months there was a marked decrease in the prevalence of smokers. Compared with a control group, the effect still remained after one year. In the period 1975–1980, a new trend in smoking among young people in Norway was recorded. Irrespective of grade and sex, the proportion of young people smoking daily decreased. The decrease was somewhat stronger for girls than for boys. 相似文献

In two experiments, a bias in lineups was examined, which has mostly been ignored in previous research. The psychic state of the suspects differs from the state of the fillers, in that they face a situation that can lead to personal loss (if they are identified) or relief (if they are not identified). This state might result in detectable behavioural cues, thus making the lineup unfair. Lineups were conducted with randomly chosen mock suspects who were promised money if they were not identified. Lineup samples were recorded on videotape once before the selection of the mock suspect (serving as a control) and once afterwards. The probability of identification of the mock suspect was significantly increased in the latter compared to the former condition. Copyright © 2004 John Wiley & Sons, Ltd. 相似文献

A review is given of scores on various cognitive measures, comparing groups of ethnic Dutch and non‐Western immigrants using a large number of datasets. The research shows that there are large group differences in school results, work proficiency, and g for Turks, Moroccans, Surinamese, Netherlands Antilleans, and Indonesians from the Moluccans compared with ethnic Dutch. However, South‐East Asians score higher, and persons with one immigrant and one ethnic Dutch parent score only slightly below the mean of the Dutch. When comparing first‐generation disadvantaged immigrant groups with later generations the data show substantial improvements for g, a remarkable stability of educational differences for younger children, and a clear improvement in educational achievement at the end of primary school. Indirect data on intergenerational improvements in work proficiency appear suggestive of a trend of closing gaps. Some of the data reflect higher cognitive capacities over time, and this enhances integration of immigrants into Dutch society. Causes of group differences and improvements in mean level of g are discussed. Copyright © 2004 John Wiley & Sons, Ltd. 相似文献

ABSTRACT— Pavlovian fear conditioning is a widely used model of the acquisition and extinction of fear. Neural findings suggest that the amygdala is the core structure for fear acquisition, whereas prefrontal cortical areas are given pivotal roles in fear extinction. Forty-eight volunteers participated in a fear-conditioning experiment, which used fear potentiation of the startle reflex as the primary measure to investigate the effect of two genetic polymorphisms (5-HTTLPR and COMTval158met) on conditioning and extinction of fear. The 5-HTTLPR polymorphism, located in the serotonin transporter gene, is associated with amygdala reactivity and neuroticism, whereas the COMTval158met polymorphism, which is located in the gene coding for catechol-O-methyltransferase (COMT), a dopamine-degrading enzyme, affects prefrontal executive functions. Our results show that only carriers of the 5-HTTLPR s allele exhibited conditioned startle potentiation, whereas carriers of the COMT met/met genotype failed to extinguish conditioned fear. These results may have interesting implications for understanding gene-environment interactions in the development and treatment of anxiety disorders. 相似文献

ABSTRACT The present study investigates the commonly found age–conservatism relationship by combining insights from studies on the development of personality and motivated social cognition with findings on the relationships between these factors and conservative beliefs. Based on data collected in Belgium ( N =2,373) and Poland ( N =939), we found the expected linear effect of age on indicators of social-cultural conservatism in Belgium and Poland and the absence of such effects for indicators of economic-hierarchical conservatism. We further demonstrated that these effects of age on indicators of cultural conservatism in both countries were (in part) mediated through the personality factor Openness to Experience and the motivated cognition variable Need for Closure. The consistency of these findings in two countries with a very dissimilar sociopolitical history attests to the importance of the developmental perspective for the study of the relationship between age and conservatism. 相似文献

This study examines the simultaneous effects of need for closure (NFC) and relative cognitive capacity on invested effort and task performance within the integrative analysis framework using behavioral data. Two main results were obtained. First, the authors revealed a significant interaction effect between relative cognitive capacity (manipulated through task difficulty) and NFC (manipulated through time pressure, noise, and fear of invalidity as well as assessed by an individual differences measure) on effort investment. Second, contrary to dispositional NFC, manipulations yielded a "dual effect" because they negatively affected task performance as well as invested effort. The latter result was interpreted as an indication that noise and time pressure manipulations also tax cognitive resources. The two main findings are discussed and the authors go further into the divergences between dispositional and manipulated NFC. 相似文献

The Basic Character Inventory (BCI) contains 136 items, 17 lower-order personality factors and three higher-order personality factors derived from psychoanalytic theory: Oral, Obsessive Compulsion, and Hysteria. Previous research that investigated the BCI's psychometric properties examined small, special populations and did not use modern statistical methods to validate the BCI. The present study validates the BCI via confirmatory factor analyses using a large sample of 6,285 Norwegian nursing and teaching students. Reliability, convergent validity, and divergent validity of the BCI were also assessed. Results indicated general support for the original BCI factor structure in a reduced form of the BCI that possesses strong reliability and validity, and is suitable for use in time-limited measurement settings. 相似文献
