Hierarchical agglomerative cluster analysis (HACA) may yield different solutions under permutations of the input order of the data. This instability is caused by ties, either in the initial proximity matrix or arising during agglomeration. The authors recommend to repeat the analysis on a large number of random permutations of the rows and columns of the proximity matrix and select a solution with the highest goodness-of-fit. This approach was implemented in an SPSS add-in, PermuCLUSTER, which can perform all HACA methods of SPSS. Analyses of 2 data sets show that (a) results are affected by input order, (b) instability in one method co-occurs with instability in other methods, and (c) some instability effects are more dramatic because they occur at higher agglomeration levels. 相似文献

Therapeutic use of humor in patients with antisocial personality disorders is scarcely studied until now. However, therapeutic use of humor could contribute to a growth of social-emotional and moral awareness and capacities, enhancement of self-insight and reality testing, and associated therapeutic progress in these patients. Suggestions are made for a) adequate and safe use of humor in the therapeutic context, and b) effective selection of patients. More research is needed into the effects and adequate strategies of therapeutic humor in different categories of antisocial patients. Furthermore, it is also necessary to investigate how humor could be integrated well in various psychotherapeutic approaches 相似文献

A wave of recent behavioral studies has generated a new wealth of parametric observations about serial order behavior. What was a trickle of neurophysiological studies has grown to a steady stream of probes of neural sites and mechanisms underlying sequential behavior. Moreover, simulation models of serial behavior generation have begun to open a channel to link cellular dynamics with cognitive and behavioral dynamics. Here we review major results from prominent sequence learning and performance tasks, namely immediate serial recall, typing, 2 x N, discrete sequence production, and serial reaction time. These tasks populate a continuum from higher to lower degrees of internal control of sequential organization and probe important contemporary issues such as the nature of working-memory representations for sequential behavior, and the development and role of chunks in hierarchical control. The main movement classes reviewed are speech and keypressing, both involving small amplitude movements amenable to parametric study. A synopsis of serial order models, vis-a-vis major empirical findings leads to a focus on competitive queuing (CQ) models. Recently, the many behavioral predictive successes of CQ models have been complemented by successful prediction of distinctively patterned electrophysiological recordings. In lateral prefrontal cortex, parallel activation dynamics of multiple neural ensembles strikingly matches the parallel dynamics predicted by CQ theory. An extended CQ simulation model--the N-STREAMS neural network model--exemplifies ongoing attempts to accommodate a broad range of both behavioral and neurobiological data within a CQ-consistent theory. 相似文献

On the basis of evidence from studies of the naming and reading of numerals, Ferrand (1999) argued that the naming of objects is slower than reading their names, due to a greater response uncertainty in naming than in reading, rather than to an obligatory conceptual preparation for naming, but not for reading. We manipulated the need for conceptual preparation, while keeping response uncertainty constant in the naming and reading of complex numerals. In Experiment 1, participants named three-digit Arabic numerals either as house numbers or clock times. House number naming latencies were determined mostly by morphophonological factors, such as morpheme frequency and the number of phonemes, whereas clock time naming latencies revealed an additional conceptual involvement. In Experiment 2, the numerals were presented in alphabetic format and had to be read aloud. Reading latencies were determined mostly by morphophonological factors in both modes. These results suggest that conceptual preparation, rather than response uncertainty, is responsible for the difference between naming and reading latencies. 相似文献

Philip Clayton's God and Contemporary Science is summarized and discussed. Clayton presents a theological reading of biblical texts. In my opinion, science-and-religion studies should deal more substantially with insights of secular studies on the situated character of these texts. Clayton uses the relationship between mind and brain as analogy for the relationship between God and the world. This runs the risk of understanding God as analogous to the mind and hence secondary and emergent relative to the world. Besides, Clayton's arguments for “mental causation” are wanting. But then, why should a defender of panentheism decouple the mental and the material? 相似文献

The present study investigated the associations between temperamental reactivity, drinking motives, alcohol consumption and
alcohol-related consequences. Furthermore, it investigated whether drinking motives mediate the relations between temperamental
reactivity and the alcohol use variables. The sample consisted of 188 adolescents (64.9% boys) between the ages of 13–20 years
(M
age
= 16.9, SD = 1.32). Results revealed that the temperament factors of high BAS fun seeking and high negative affectivity were related
to alcohol consumption and alcohol-related consequences respectively. Furthermore, high social and enhancement motives and
low conformity motives were associated with alcohol consumption, whereas high coping-depression motives were associated with
alcohol-related consequences. Finally, the relation between BAS fun seeking and alcohol consumption was mediated by enhancement
and social motives and the association between negative affectivity and alcohol-related consequences was mediated by coping-depression
motives. These results highlight the importance of focusing on temperament profiles and their associated drinking motives
in the prevention and intervention of alcohol use problems among adolescents. 相似文献

Previous research shows that men are more risk prone than women; single men take more risks than men involved in a romantic relationship; and men increase their level of risk taking in the presence of observers. We extend the existing literature with two studies. Our first study demonstrates that romantically involved men take less risk in the presence of women to the extent that they are more committed to their current partner. No such effect occurs in the presence of males. Our second study is an experiment revealing that men's beliefs about women's attitudes about risk taking causally influence men's level of risk taking. We developed a new measure of risk-taking—the Marble Risk Task, reminiscent of the computerized Balloon Analogue Risk Task (Lejuez et al., 2002), but designed to measure risk-taking outside of the laboratory and with real financial stakes—to show that single men adjust their level of risk taking to match what they believe women find attractive. Men involved in a relationship did the opposite: they adjust their behavior to not match what they believe women consider attractive—possibly with the goal of relationship maintenance. 相似文献

Reports the retraction of "The referents of trait inferences: The impact of trait concepts versus actor-trait links on subsequent judgments" by Diederik A. Stapel, Willem Koomen and Joop van der Pligt (Journal of Personality and Social Psychology, 1996[Mar], Vol 70[3], 437-450). This retraction follows the results of an investigation into the work of Diederik A. Stapel (further information on the investigation can be found here: https://www.commissielevelt.nl/). The Drenth Committee has found evidence of fraud, leading to the conclusion that fraud is most likely in the data supplied by Diederik A. Stapel. His co-authors were unaware of his actions and were not involved in the collection of the likely fraudulent data. (The following abstract of the original article appeared in record 1996-03014-002.) The authors investigated the hypothesis that when trait inferences refer to abstract behavior labels they act as a general interpretation frame and lead to assimilation in subsequent judgments of an ambiguous target, whereas when they refer to a specific actor-trait link they will be used as a scale anchor and lead to contrast. Similar to G. B. Moskowitz and R. J. Roman's (see record 1992-31124-001) study, participants who were instructed to memorize trait-implying sentences showed assimilation, and participants who were instructed to form an impression of the actors in these sentences showed contrast. However, exposure to trait-implying sentences that described actors with real names and were accompanied with photos of the actors resulted in contrast under both memorization and impression instructions (Experiment 1). Furthermore, contrast ensued when trait-implying sentences were accompanied with information that suggested a person attribution, whereas assimilation ensued when that information suggested a situation attribution, independent of processing goals (Experiment 2). These findings are interpreted as support for referent-based explanations of the consequences of trait inferences. (PsycINFO Database Record (c) 2012 APA, all rights reserved). 相似文献
