The relationship between inspection time (IT) and paper-and-pencil tests of cognitive ability is well documented. However, the extent to which IT relates to cognitive ability through general intelligence or through group factors such as performance has not been fully addressed. Another unresolved issue is whether IT relates to psychometric intelligence independent from other elementary cognitive tasks. The current study examined these issues in a sample of 6–13-year-old twins drawn from the Western Reserve Twin Project (WRTP) (n=568 participants). Analyses suggest that IT and other elementary tasks predict general intelligence. IT also predicts Performance ability while other elementary tasks do not. Furthermore, IT contributes variance to cognitive ability independent from other elementary tasks. These suggest that multiple indices of elementary cognitive ability are necessary to fully understand their relationship with complex psychometric measures. 相似文献

In a study designed to investigate the respective roles of religious fundamentalism and right‐wing authoritarianism as predictors of prejudice against racial minorities and homosexuals, participants (47 males, 91 females) responded to a series of questionnaire measures of these constructs. Data were analyzed using multiple regression. Consistent with previous research, authoritarianism was a significant and strong positive predictor of both forms of prejudice. With authoritarianism statistically controlled, however, fundamentalism emerged as a significant negative predictor of racial prejudice but a positive predictor of homosexual prejudice. In a second study, we conducted parallel multiple regressions using the correlations from two previously published studies. The Study 1 results were replicated exactly, except that fundamentalism was a nonsignificant predictor of homosexual prejudice. We interpret the results as evidence that Christian fundamentalism consists of a second major component other than authoritarianism—related to Christian belief content—that is inversely related to some forms of prejudice (including racial prejudice) but not others (e.g., homosexual prejudice). 相似文献

This questionnaire study was designed to confirm and further explore an earlier finding of a gender difference in post-termination patient-analyst contact, as well as to assess whether practices regarding post-termination contact have changed in the five-year interval since the first study. The hypothesis that women analysts are more likely to have post-termination contact with their analysands than men analysts was confirmed by the present study. Analysts who report thinking frequently about their most significant analyst are contacted by a much larger proportion of prior patients than those who rarely think about their analyst. Further, women analysts are more likely to feel they benefited from the analysis they consider their most significant analysis, and to feel positively about that analyst. In 1994, analysts were much more accepting of and more likely to propose post-termination contact than in 1989. What the analyst reports he/she says to the patient is associated with the likelihood of such contact. 相似文献

This paper presents a model of the cognitive processes that precede decisions to help another person. The empathy‐prospect model predicts that potential helpers make decisions in much the same way as decision makers in other contexts do (i.e., they evaluate prospects) and that perceptions of need and the empathic reactions and intentions to help that they generate will be stronger for people observing losses rather than gains. The model also predicts that intentions to help should increase when (a) the predicament is serious, (b) money is not involved, or (c) help entails few costs for the potential altruist. The results from 2 experiments provide clear support for these predictions. The findings suggest that (a) the gains or losses of another person contribute to perceptions of that person's needs and feelings of empathy, (b) empathy is the primary proximal determinant of prosocial motivations, and (c) potential losses that are serious accentuate altruistic reactions. 相似文献

In this paper I argue that the ontological interpretation of the concepts of reduction and emergence is often misleading in
the philosophy of science and should nearly always be eschewed in favor of an epistemological interpretation. As a paradigm
case, an example is drawn from the philosophy of chemistry to illustrate the drawbacks of “ontological reduction” and “ontological
emergence,” and the virtues of an epistemological interpretation of these concepts. 相似文献

The role of drug expectancy in the control of human drug seeking 总被引:2,自引:0,他引:2

Human drug seeking may be goal directed in the sense that it is mediated by a mental representation of the drug or habitual in the sense that it is elicited by drug-paired cues directly. To test these 2 accounts, the authors assessed whether a drug-paired stimulus (S+) would transfer control to an independently trained drug-seeking response. Smokers were trained on an instrumental discrimination that established a tobacco S+ in Experiment 1 and a tobacco and a money S+ in Experiment 2 that elicited an expectancy of their respective outcomes. Participants then learned 2 new instrumental responses, 1 for each outcome, in the absence of these stimuli. Finally, in the transfer test, each S+ was found to augment performance of the new instrumental response that was trained with the same outcome. This outcome-specific transfer effect indicates that drug-paired stimuli controlled human drug seeking via a representation or expectation of the drug rather than through a direct stimulus-response association. 相似文献

We address points raised by Zajonc and Sulloway, who reject findings showing that birth order has no effect on intelligence. Many objections to findings of null birth-order results seem to stem from a misunderstanding of the difference between study designs where birth order is confounded with true causal influences on intelligence across families and designs that control for some of these influences. We discuss some of the consequences of not appreciating the nature of this difference. When between-family confounds are controlled using appropriate study designs and techniques such as multilevel modeling, birth order is shown not to influence intelligence. We conclude with an empirical investigation of the replicability and generalizability of this approach. 相似文献

Our recent work suggests that infants begin to change their hand and joint kinematics in the presence of a toy months before the onset of purposeful reaching. Moreover, these 'toy-oriented' changes in hand kinematics cluster into Early, Mid and Late phases. The purpose of the present study was to test hypotheses regarding toy-oriented changes in joint kinematics in the same infants. METHODS: Thirteen infants were observed every other week from 8 weeks up to the first week of reaching around 20 weeks. At each session, a high-speed motion analysis system recorded infants' arm movements with and without a toy present. RESULTS: During the Early phase, infants scaled down their movements. In contrast, during the Mid phase infants scaled up their movements and did not change the relationship between the shoulder and elbow for speed and smoothness-related variables. In addition, infants showed toy-oriented changes such as increase in shoulder flexion and adduction. In the Late phase, infants continued to produce toy-oriented changes in shoulder orientation, and increased shoulder excursion and speed relative to the elbow. Thus, the toy-oriented changes in hand kinematics in the Mid and Late phases [Bhat, A. N., & Galloway, J. C. (2006). Toy-oriented changes in early arm movements of young infants: Hand kinematics. Infant Behavior and Development, 29(3), 358-372] more closely followed changes in shoulder kinematics. Lastly, results are discussed in terms of shoulder-elbow dissociations, speed-amplitude relationships, and the key role of spontaneous movements in the development of reaching. 相似文献

This meta-analysis of 172 studies (N = 2,263 anxious,N = 1,768 nonanxious) examined the boundary conditions of threat-related attentional biases in anxiety. Overall, the results show that the bias is reliably demonstrated with different experimental paradigms and under a variety of experimental conditions, but that it is only an effect size of d = 0.45. Although processes requiring conscious perception of threat contribute to the bias, a significant bias is also observed with stimuli outside awareness. The bias is of comparable magnitude across different types of anxious populations (individuals with different clinical disorders, high-anxious nonclinical individuals, anxious children and adults) and is not observed in nonanxious individuals. Empirical and clinical implications as well as future directions for research are discussed. 相似文献

This study used 3 generations and 21 years of prospective data to test models of intergenerational transmission of substance use and substance use risk. Thus, the study extends prior studies in the field that have focused predominantly on substance abuse. The association between the grandparental generation's (G1 mother and father) and the parental generation's (G2 father) alcohol use and illicit drug use was hypothesized to be mediated by G2's poor inhibitory control. Additionally, G1's poor discipline of G2 was hypothesized to be directly associated with G2's substance use as well as to partially mediate the association between G1's substance use and G2's inhibitory control. In turn, G2's substance use in late adolescence was expected to be associated with its offspring's (G3) poor inhibitory control at age 3 years. Findings partially supported the predictions and varied by substance. For alcohol use, only cross-generational associations in use were found. For illicit drugs, both poor inhibitory control and poor discipline played some mediational role in cross-generational use. 相似文献
