A 16-element movement sequence was taught under part-whole and whole-practice conditions. Participants (N = 18) produced a right-arm lever movement to sequentially presented target locations. The authors constructed part-whole practice by providing practice on only the 1st 8 elements on the 1st day of practice (100 repetitions of the 8-element sequence) and on all 16 elements on the 2nd day of practice (100 repetitions of the 16-element sequence). The whole-practice group practiced all 16 elements on both days (100 repetitions of the 16-element sequence per day). No differences in sequence structure or in movement duration of the 16-element sequence were noted on the retention test (Day 3). On transfer tests in which the 1st and last 8 elements were tested separately, however, the participants in the part-whole practice group performed more quickly than the participants in the whole-practice group, especially on the last 8 elements. Participants in the whole-practice group appeared to code the sequence so that it was relatively difficult to fully partition it into separate movements. Thus, on the transfer tests, there continued to be residual effects of the 8 elements that did not have to be produced but slowed down the rate of responding for the whole-practice group. That finding was not observed for the part-whole practice group. 相似文献

A six-factor structure of personality-descriptive adjectives: solutions from psycholexical studies in seven languages 总被引:5,自引:0,他引:5
Ashton MC Lee K Perugini M Szarota P de Vries RE Di Blas L Boies K De Raad B 《Journal of personality and social psychology》2004,86(2):356-366
Standard psycholexical studies of personality structure have produced a similar 6-factor solution in 7 languages (Dutch, French, German, Hungarian, Italian, Korean, Polish). The authors report the content of these personality dimensions and interpret them as follows: (a) a variant of Extraversion, defined by sociability and liveliness (though not by bravery and toughness); (b) a variant of Agreeableness, defined by gentleness, patience, and agreeableness (but also including anger and ill temper at its negative pole); (c) Conscientiousness (emphasizing organization and discipline rather than moral conscience); (d) Emotionality (containing anxiety, vulnerability, sentimentality, lack of bravery, and lack of toughness, but not anger or ill temper); (e) Honesty-Humility; (f) Intellect/Imagination/Unconventionality. A potential reorganization of the Big Five factor structure is discussed. 相似文献

The interpersonal effects of anger and happiness in negotiations 总被引:2,自引:0,他引:2
Three experiments investigated the interpersonal effects of anger and happiness in negotiations. In the course of a computer-mediated negotiation, participants received information about the emotional state (anger, happiness, or none) of their opponent. Consistent with a strategic-choice perspective, Experiment 1 showed that participants conceded more to an angry opponent than to a happy one. Experiment 2 showed that this effect was caused by tracking--participants used the emotion information to infer the other's limit, and they adjusted their demands accordingly. However, this effect was absent when the other made large concessions. Experiment 3 examined the interplay between experienced and communicated emotion and showed that angry communications (unlike happy ones) induced fear and thereby mitigated the effect of the opponent's experienced emotion. These results suggest that negotiators are especially influenced by their opponent's emotions when they are motivated and able to consider them. 相似文献

We summarize five studies of our large-scale research program, in which we examined aspects of contour-based object identification
and segmentation, and we report on the stimuli we used, the norms and data we collected, and the software tools we developed.
The stimuli were outlines derived from the standard set of line drawings of everyday objects by Snodgrass and Vanderwart (1980).
We used contour curvature as a major variable in all the studies. The total number of 1,500 participants produced very solid,
normative identification rates of silhouettes and contours, straight-line versions, and fragmented versions, and quite reliable
benchmark data about saliency of points and object segmentation into parts. We also developed several software tools to generate
stimuli and to analyze the data in nonstandard ways. Our stimuli, norms and data, and software tools have great potential
for further exploration of factors influencing contour-based object identification, and are also useful for researchers in
many different disciplines (including computer vision) on a wide variety of research topics (e.g., priming, agnosia, perceptual
organization, and picture naming). The full set of norms, data, and stimuli may be downloaded fromwww.psychonomic.org/archive/. 相似文献

Global and local processing of hierarchical visual stimuli in tufted capuchin monkeys (Cebus apella)
Spinozzi G De Lillo C Truppa V 《Journal of comparative psychology (Washington, D.C. : 1983)》2003,117(1):15-23
Capuchin monkeys' (Cebas apella) relative accuracy in the processing of the global shape or the local features of hierarchical visual stimuli was assessed. Three experiments are presented featuring manipulations of the arrangement and the density of the local elements of the stimuli. The results showed a clear advantage for local level processing in this species, which is robust under manipulations of the density of the local elements of the stimuli. By contrast the density of the component elements linearly affected accuracy in global processing. These findings, which support those from other studies in which a local superiority emerged in animals, challenge the generality of early claims concerning the adaptive value of global advantage in the processing of hierarchical visual patterns. 相似文献

The Millon Clinical Multiaxial Inventory (MCMI-II and MCMI-III) and the Minnesota Multiphasic Personality Inventory (MMPI-2)
were applied to 263 Dutch inpatient substance abusers with multiple psychiatric diagnoses, and the results compared with those
of 306 North-American substance abusers studied by Ward (1995). We looked for structural similarity both across groups (per instrument) and across the two instruments (per sample), using principal components analysis and congruence analysis. The component structure found by Ward was partly
replicated in the Dutch group, thus cross-validating the use of the two instruments with these patients. Moreover, as found
by Ward, the MMPI-2 content and supplementary scales of the Dutch sample proved to be important determinants of the first
three MMPI-2 components, adding to convergent validity. Questions remained about the influence of the (dis)continuity of MCMI-II
and MCMI-III on the replicability of the MCMI components. 相似文献

Accountability and cooperation in social dilemmas: The influence of others’ reputational concerns 总被引:1,自引:0,他引:1
David?De?CremerEmail author Müriel?Barker 《Current psychology (New Brunswick, N.J.)》2003,22(2):155-163
The present study examined the assumption that non-anonymous choices in social dilemmas (i.e., choices for which one is accountable)
may influence cooperation, but only to the extent that decision-makers believe that the others will evaluate non-cooperation
negatively. Based on a recent review by Kerr (1999), it was expected that under conditions of accountability, decision-makers
would cooperate more when they believed that the others within the group were also concerned about their social reputation
and therefore were aware of the social norm of cooperation within social dilemmas. As a consequence, it could be expected
that non-cooperation by oneself would be evaluated negatively by those others since they seemed to be aware of what ought
to be done in a social dilemma (i.e., the norm of cooperation). Results confirmed these predictions and, in addition, also
showed that greater willingness to cooperate was associated with stronger feelings of collective concern. The findings are
discussed in terms of recent literature on anonymity effects in social dilemmas.

Five competing models specifying the factor structure underlying the Wechsler Memory Scale-Third Edition (D. Wechsler, 1997b) primary subtest scores were evaluated in a sample of patients with intractable temporal lobe epilepsy (N = 254). Models specifying separate immediate and delayed constructs resulted in inadmissible parameter estimates and model specification error. There were negligible goodness-of-fit differences between a 3-factor model of working memory, auditory memory, and visual memory and a nested--more parsimonious--2-factor model of working memory and general memory. The results suggest that specifying a separate visual memory factor provides little advantage for this sample--an unexpected finding in a population with lateralized dysfunction, for which one might have predicted separate auditory and visual memory dimensions. 相似文献

N-Methyl-D-aspartate (NMDA) receptors appear to be involved in CS processing and memory consolidation. The present paper analyzed the effect of the non-competitive NMDA receptor antagonist Dizocilpine maleate (MK-801) on Latent Inhibition (LI)-retarded learning of a CS-US association after to-be-CS preexposures at time of testing, using Wistar rats as experimental subjects. If NMDA receptors are involved in CS processing, MK-801 administration should affect LI. In fact, previous experiments revealed that a 2.0mg/kg MK-801 dose, administered 20 h before preexposure and conditioning, abolished LI in a conditioned taste-aversion paradigm. In the present paper, MK-801 (0.2 mg/kg) was either injected after preexposure, after conditioning, or after both preexposure and conditioning stages. LI was abolished when MK-801 was injected after preexposure, but not when it was injected after conditioning. These results support the role of NMDA receptors in CS processing and memory consolidation. 相似文献

This work presents a critical analysis of Pavlov's influence that goes beyond the conventional view: that which reduces his influence in American psychology to the behaviorism of Watson and Hull. In order to understand the nature of the Russian physiologist's influence in American psychology, we propose a distinction between three approaches to it: 1) the symbolic approach, on representing a model of the possibility of constructing an objective psychology; 2) the methodological approach, given the importance of the technique of conditional reflexes; and 3) the theoretical approach, which is derived from his theory of higher nervous activity. This perspective permits us to suggest that most of Pavlov's influence on behaviorism was of a symbolic and methodological nature--though the methodological influence also reached other authors that did not belong to the behaviorist traditions, as was the case of Mateer. As far as the theoretical influence is concerned, our work proposes that it is more visible in authors such as Gantt and Liddell, or even in authors such as Boldirev, Director of the Pavlovian Laboratory at the Battle Creek Sanitarium in Michigan. The case of Gantt is especially interesting because, in addition to his important contributions, he played an essential role in the foundation of the Pavlovian Society, and the journal Conditional Reflex. What our work proposes is that to understand the nature of Pavlov's influence in American psychology it is necessary to take into account the very characteristics of that psychology: its pragmatic interests, its methodological rigor, the dominant systems of neo-behavioral theory and the changes that occurred after the Second World War. 相似文献
