Thematically related concepts like coffee and milk are judged to be more similar than thematically unrelated concepts like coffee and lemonade. We investigated whether thematic relations exert a small effect that occurs consistently across participants (i.e., a generalized model), or a large effect that occurs inconsistently across participants (i.e., an individualized model). We also examined whether difference judgments mirrored similarity or whether these judgments were, in fact, non-inverse. Five studies demonstrated the necessity of an individualized model for both perceived similarity and difference, and additionally provided evidence that thematic relations affect similarity more than difference. Results suggest that models of similarity and difference must be attuned to large and consistent individual variability in the weighting of thematic relations. 相似文献

The 3D cube figures used by Shepard and Metzler [Shepard, R. N., & Metzler, J. (1971). Mental rotation of three-dimensional objects. Science, 171, 701-703] have been applied in a broad range of studies on mental rotation. This note provides a brief background on these figures, their general use in cognitive psychology and their role in studying spatial behavior. In particular, it is pointed out that large sex differences with the 3D mental rotation figures tend to be observed only in particular tasks, such as the Vandenberg and Kuse test [Vandenberg, S. G., & Kuse, A. R. (1978). Mental rotations, a group test of three-dimensional spatial visualization. Perceptual and Motor Skills, 47, 599-604] that involve multiple figures within a single problem. In contrast, pairwise presentation of the same 3D figures yields either small or no significant sex differences. In the context of the very broad range of ongoing research done with 3D figures, and the desirability of uniformity in the stimulus material used, we introduce a library of 16 cube mental rotation figures, each presented in orientations ranging from 0 to 360 degr in 5 degr steps, and with its mirror image, for a total of 2336 figures. This library, freely available to researchers, will help in the creation of mental rotation tasks both for presentation on the computer screen and for pencil and paper applications. 相似文献

Abstract: In the present study, the effects of verbal working memory (VWM) and cumulative linguistic knowledge (CLK) on reading comprehension were investigated using an individual difference approach. We examined whether VWM and CLK are distinct verbal factors and whether each has independent influences on reading comprehension. VWM was tested using the Japanese Reading Span Test (RST). CLK was assessed using information, vocabulary, and similarity subtests of the Wechsler Adult Intelligence Scale‐Revised (WAIS‐R), as well as with the Hyakurakan kanji reading test. The differences between VWM and CLK were examined using correlation analyses between reading comprehension scores, and digit forward and backward span scores. The results showed that VWM and CLK were independent of each other, and that VWM and CLK independently contributed to reading comprehension. The obtained correlations also showed that CLK was independent of any type of short‐term memory, and that the VWM measured using the RST had little correlation with digit span. 相似文献

In psychological research, one often aims at explaining individual differences in S-R profiles, that is, individual differences
in the responses (R) with which people react to specific stimuli (S). To this end, researchers often postulate an underlying
sequential process, which boils down to the specification of a set of mediating variables (M) and the processes that link
these mediating variables to the stimuli and responses under study. Obviously, a crucial task is to chart how the individual
differences in the S-R profiles are caused by individual differences in the S-M link and/or by individual differences in the
M-R link. In this paper we propose a new model, called CLASSI, which was explicitly designed for this task. In particular,
the key principle of CLASSI consists of reducing the S, M, and R nodes of a sequential process to a few mutually exclusive
types and inducing an S-M and an M-R person typology from the data, with the S-M person types being characterized in terms
of if S type then M type rules and the M-R person types in terms of if M type then R type rules. As such, the S-M and M-R person types and their associated if–then rules represent the important individual
differences in the S-M and M-R links of the sequential process under study. An algorithm to fit the CLASSI model is described
and evaluated in a simulation study. An application of CLASSI to data from the behavioral domain of anger and sadness is discussed.
Finally, we relate CLASSI to other methods and discuss possible extensions.

Despite its avowed goal of understanding individual behavior, the field of behavior analysis has largely ignored the determinants of consistent differences in level of performance among individuals. The present article discusses major findings in the study of individual differences in intelligence from the conceptual framework of a functional analysis of behavior. In addition to general intelligence, we discuss three other major aspects of behavior in which individuals differ: speed of processing, working memory, and the learning of three-term contingencies. Despite recent progress in our understanding of the relations among these aspects of behavior, numerous issues remain unresolved. Researchers need to determine which learning tasks predict individual differences in intelligence and which do not, and then identify the specific characteristics of these tasks that make such prediction possible. 相似文献

Sex differences and lifestyle-dependent shifts in the attunement of self-esteem to self-perceived mate value: Hints to an adaptive mechanism? 总被引:1,自引:0,他引:1
It has been suggested that self-esteem is reactive to signs of social rejection, and that this “sociometer” mechanism becomes attuned to those personal attributes that affect social acceptance by significant others. Based on evolutionary models of human mating, we predicted that self-esteem should be more attuned to self-perceived mate value in men (when compared to women) who pursue short-term mating tactics, especially if they are unsuccessful therein. In a web-based study (N = 2670), we found that mate value self-perceptions had a stronger effect on self-esteem on those who had less short-term mating success in the past. However, being in a committed relationship or parenthood reduced the impact of mate value self-perceptions. As expected, these effects were specific to men. These results are suggestive of a psychological mechanism based on adaptive sociometer attunements that could help men to choose their optimal mating tactic and might thus partly explain intrasexual differences in sociosexuality. 相似文献

This research sets out to examine individual variations in perceptions of display rules. Based upon Mischel and Shoda’s [Mischel, W., & Shoda, Y. (1995). A cognitive-affective system theory of personality: Reconceptualizing situations, dispositions, dynamics, and invariance in personality structure. Psychological Review, 102, 246–268.] model of the Cognitive-Affective Personality System (CAPS), we proposed that extraversion and neuroticism would serve to explain within-cultural individual differences and within-individual differences in endorsement of display rules. To test this hypothesis, participants reported the expressivity level of the display rule they endorsed by responding to the revised version of the Display Rule Assessment Inventory. Multi-level analyses showed that compared to those of introverts, the display rules of extraverts tended to be more suppressive when the relationship was distant rather than close. Extraversion also enhanced a neurotic’s degree of suppression in public compared to private situations. Processes describing how personality interacts with situations in personalizing display rules were offered in light of the CAPS model to account for these interactions between personality and situation in the operation of display rules for emotional expression. 相似文献

The role of gratitude in the development of social support, stress, and depression: Two longitudinal studies 总被引:1,自引:0,他引:1

In two longitudinal studies, the authors examined the direction of the relationships between trait gratitude, perceived social support, stress, and depression during a life transition. Both studies used a full cross-lagged panel design, with participants completing all measures at the start and end of their first semester at college. Structural equation modeling was used to compare models of direct, reverse, and reciprocal models of directionality. Both studies supported a direct model whereby gratitude led to higher levels of perceived social support, and lower levels of stress and depression. In contrast, no variable led to gratitude, and most models of mediation were discounted. Study 2 additionally showed that gratitude leads to the other variables independently of the Big Five factors of personality. Overall gratitude seems to directly foster social support, and to protect people from stress and depression, which has implications for clinical interventions. 相似文献

The two fundamental dimensions assumed to underlie emotional experience—pleasure and arousal—are considered to be independent across individuals. We present evidence from an experience sampling study demonstrating that this independence does not necessarily hold when considering the affective experiences of a single individual. Participants (N = 80) reported how they were feeling in terms of pleasure and arousal nine times a day for seven days. The data showed that, although on average pleasure and arousal were independent, within-person pleasure–arousal associations substantially varied and ranged from strongly positive to strongly negative. This finding demonstrates that pleasant/unpleasant feelings usually co-occur with high arousal for some (reflecting joy/stress), but with low arousal for others (reflecting relaxation/sadness) and that persons differ in whether arousal is usually pleasant or unpleasant. These differences were found to be related to dispositional reward responsiveness, with high reward responsive individuals being characterized by a positive relation between pleasure and arousal and vice versa. 相似文献
