Word-fragment completion is a frequently used test in implicit memory research. A database of 196 Spanish fragments was recently published (Dasí, Soler, & Ruiz, 2004) in which the fragments were described for indices, such as difficulty, familiarity, frequency, number of meanings, and so on (www.psychonomic.org/archive). In this work, a new index, the priming index, is described for the same 196 fragments. This index is calculated for each fragment by subtracting the difficulty index (the proportion of correct completion when the fragment is not studied) from the proportion of correct completion when the fragment is studied, and it means the capacity of an item to be primed. In order to determine whether the new index performs well, we have replicated some important experimental effects, such as priming, frequency, and difficulty. We consider that this index can help researchers to better select stimuli for fragment-completion tasks. 相似文献
This paper is about a tension between two theses. The first is Value of Evidence: roughly, the thesis that it is always rational for an agent to gather and use cost-free evidence for making decisions. The second is Rationality of Imprecision: the thesis that an agent can be rationally required to adopt doxastic states that are imprecise, i.e., not representable by a single credence function. While others have noticed this tension, I offer a new diagnosis of it. I show that it arises when an agent with an imprecise doxastic state engages in an unreflective inquiry, an inquiry where they revise their beliefs using an updating rule that doesn't satisfy a weak reflection principle. In such an unreflective inquiry, certain synchronic norms of instrumental rationality can make it instrumentally irrational for an agent to gather and use cost-free evidence. I then go on to propose a diachronic norm of instrumental rationality that preserves Value of Evidence in unreflective inquiries. This, I suggest, may help us reconcile this thesis with Rationality of Imprecision. 相似文献
Five rats were submitted to a signaled free-operant avoidance contingency. Throughout the experiment, shock intensity was varied from 0.1 to 8.0 mA, with shock duration constant at 200 milleseconds. Results indicate: (a) an all-or-none effect of shock intensity on response and shock rates, on percentage of shocks avoided, and on frequency of occurrence of responding during the preshock stimulus; and (b) no systematic effect of shock intensity on stimulus control, measured either by the percentage of stimulus presentations accompanied by a response or by the percentage of responses that occurred during those preshock stimuli. Such results indicate that for each subject there is a minimum shock intensity necessary to establish and maintain avoidance responding; intensities higher than this minimum value have little or no effect on responding (with an upper limit for those strong intensities with a general disruptive effect on behavior). 相似文献
This study investigated the relationship between the gender and gender-role of students and their “best” university professors. Two hundred and ninety two business students in 2 universities in Atlantic Canada rated their best professors and themselves using Bem's Sex Role Inventory. Male business students were more likely than females to choose a male as their best professor, and female business students were more likely than males to choose a female as their best professor. The study also indicates that a student's own gender and gender role are significantly related to those of his/her best professor. Male professors with low femininity scores (but not necessarily high masculinity scores), and female professors who are gender-neutral (i.e., androgynous or undifferentiated) were more often chosen by students as their best professors. In general, masculinity seems to be valued more by older, part-time students with greater work experience. Implications of these findings for university teachers are discussed. 相似文献
In two studies, performance in concrete operational tasks was related to individual differences in simultaneous-successive processing. Although the studies were carried out in culturally different populations (in Canada and in India), it was observed that children who prefer simultaneous to successive processing did better in the Piagetian tasks of conservation, transitive inference, and class inclusion. But performance in class inclusion appeared to be helped by both processes in the study in India. On the whole, rational as well as empirical reasons were found to claim that simultaneous processing is utilized in the successful solution of concrete operational tasks. 相似文献
This article looks at the current usage of the term multicultural counseling and analyzes the emerging concept by identifying the premises on which it is based. It explores the potential contribution of multiculturalism to the theory and practice of counseling. The current status of training in cross-cultural and multicultural counseling is briefly reviewed, and curricular content is suggested for upgrading the preparation of multicultural counselors in light of the new standards set by the Council for Accreditation of Counseling and Related Educational Programs (CACREP). Some concrete proposals toward implementing CACREP standards are presented. 相似文献
Objective: Information about treatment side effects can increase their occurrence; breast cancer (BC) patients showed increased cognitive problem reporting (CPR) and decreased memory performance after information about cognitive side effects. The current study extends previous research on adverse information effects (AIE) by investigating (a) risk factors, (b) underlying mechanisms and (c) an intervention to reduce AIE.
Design: In an online experiment, 175 female BC patients were randomly assigned to one of three conditions. In the two experimental groups, patients were informed about the possible occurrence of cognitive problems after chemotherapy with (intervention group) or without (experimental group) reassuring information that ‘there are still patients who score well on memory tests’. In the control group, no reference to chemotherapy-related cognitive problems was made.
Main outcome measures: Main dependent measure was CPR. Four moderating and five mediating processes were examined.
Results: CPR increased with higher levels of stigma consciousness in the two experimental groups, but not in the no-information control group.
Conclusion: Merely informing patients about cognitive side effects may increase their occurrence, especially among individuals vulnerable to patient stereotypes. Adding reassuring information is not sufficient to reduce AIE. 相似文献
