When solving a simple probabilistic problem, people tend to build an incomplete mental representation. We observe this pattern in responses to probabilistic problems over a set of premises using the conjunction, disjunction, and conditional propositional connectives. The mental model theory of extensional reasoning explains this bias towards underestimating the number of possibilities: In reckoning with different interpretations of the premises (logical rules, mental model theoretical, and, specific to conditional premises, conjunction and biconditional interpretation) the mental model theory accounts for the majority of observations. Different interpretations of a premise result in a build-up of mental models that are often incomplete. These mental models are processed using either an extensional strategy relying on proportions amongst models, or a conflict monitoring strategy. The consequence of considering too few possibilities is an erroneous probability estimate akin to that faced by decision makers who fail to generate and consider all alternatives, a characteristic of bounded rationality. We compare our results to the results published by Johnson-Laird, Legrenzi, Girotto, Legrenzi, and Caverni [Johnson-Laird, P., Legrenzi, P., Girotto, V., Legrenzi, M., &; Caverni, J.

A measure of implicit sexual motives—the implicit AMORE—was constructed employing the Affect Misattribution Procedure (Payne, Cheng, Govorun, &; Stewart, 2005 Payne, B. K., Cheng, C. M., Govorun, O., &; Stewart, B. D. (2005). An inkblot for attitudes: Affect misattribution as implcit measurement. Journal of Personality and Social Psychology, 89, 277293. doi:10.1037/0022-3514.89.3.277[Crossref], [PubMed], [Web of Science ®] [Google Scholar]). Subscales paralleled the 8 dimensions identified previously by the self-report measure of sexual motives, the explicit AMORE (Hill &; Preston, 1996 Hill, C. A., &; Preston, L. K. (1996). Individual differences in the experience of sexual motivation: Theory and measurement of dispositional sexual motives. Journal of Sex Research, 33, 2745. doi:10.1080/00224499609551812[Taylor &; Francis Online], [Web of Science ®] [Google Scholar]). Confirmatory factor analyses supported the proposed 8-factor model in slightly revised form, which was confirmed based on a second independent set of participants. Consistent with hypotheses, the implicit scales correlated with nonconscious erotica-viewing behavior for women in a laboratory setting. In contrast to explicit scales, implicit scales were unrelated to self-report ratings of likely sexual behavior. Finally, self-reports of aspects of sexual behavior were generally associated with the measures of implicit motives independently of corresponding explicit motives for both women and men. The results support the conception of implicit sexual motives as related, but distinct from explicit sexual motives.  相似文献

We reanalyze the recent multilab preregistered study on ego-depletion by Hagger and Chatzisarantis (2016 Hagger, M. S., &; Chatzisarantis, N. L. D. (2016). A multilab preregistered replication of the ego-depletion effect. Perspectives on Psychological Science, 11, 546573. doi:10.1177/1745691616652873[Crossref], [Web of Science ®] [Google Scholar]) as if their data were obtained under the research program-strategy (Witte &; Zenker, 2016a Witte, E. H., &; Zenker, F. (2016a). Beyond schools—Reply to Marsman, Ly, and Wagenmakers. Basic and Applied Social Psychology, 38, 313317. doi:10.1080/01973533.2016.1227710[Taylor &; Francis Online], [Web of Science ®] [Google Scholar], 2016b Witte, E. H., &; Zenker, F. (2016b). Reconstructing recent work on macro-social stress as a research program. Basic and Applied Social Psychology, 38, 301307. doi:10.1080/01973533.2016.1207077[Taylor &; Francis Online], [Web of Science ®] [Google Scholar]). This strengthens Hagger and Chatzisarantis’s (2016 Hagger, M. S., &; Chatzisarantis, N. L. D. (2016). A multilab preregistered replication of the ego-depletion effect. Perspectives on Psychological Science, 11, 546573. doi:10.1177/1745691616652873[Crossref], [Web of Science ®] [Google Scholar]) main conclusion, because our reanalysis more directly corroborates the absence of a medium-sized, or a small-sized, ego-depletion effect (d?=?.50 under α?=?β?=?.05; d?=?.20 under α?=?β?=?.01). We explain how a smaller ego-depletion effect of d?=?.04 can be tested under similar conditions, having determined this value by maximum likelihood estimation, and compare the research program-strategy to a standard meta-analytic integration.  相似文献

Mind perception involves attributing higher functional abilities to others (e.g., saying a dog feels pain). The relationships between mind perception and psychopathology—autism, psychopathy, and schizotypy—have been revealed by K. Gray, Jenkins, Heberlein, and Wegner (2011 Gray, K., Jenkins, A. C., Heberlein, A. S., &; Wegner, D. M. (2011). Distortions of mind perception in psychopathology. Proceedings of the National Academy of Sciences of the United States of America, 108, 477479. doi:10.1073/pnas.1015493108[Crossref], [PubMed], [Web of Science ®] [Google Scholar]); however, mind perception has yet to be correlated with personality. Participants (N = 180) completed measures of personality, psychopathology, and mind perception. The psychopathology results were consistent with Gray et al. (2011 Gray, K., Jenkins, A. C., Heberlein, A. S., &; Wegner, D. M. (2011). Distortions of mind perception in psychopathology. Proceedings of the National Academy of Sciences of the United States of America, 108, 477479. doi:10.1073/pnas.1015493108[Crossref], [PubMed], [Web of Science ®] [Google Scholar]). The Big Five captured mind perception virtually as much as the three psychopathologies captured mind perception. Mind perception is not solely relevant to psychopathology; it is also relevant to everyday personality.  相似文献

Bifactor latent structures were introduced over 70 years ago, but only recently has bifactor modeling been rediscovered as an effective approach to modeling construct-relevant multidimensionality in a set of ordered categorical item responses. I begin by describing the Schmid-Leiman bifactor procedure (Schmid &; Leiman, 1957 Schmid, J. 1957. The comparability of the bi-factor and second-order factor patterns. Journal of Experimental Education, 25: 249253. [Taylor &; Francis Online], [Web of Science ®] [Google Scholar]) and highlight its relations with correlated-factors and second-order exploratory factor models. After describing limitations of the Schmid-Leiman, 2 newer methods of exploratory bifactor modeling are considered, namely, analytic bifactor (Jennrich &; Bentler, 2011 Jennrich, R. I. and Bentler, P. M. 2011. Exploratory bi-factor analysis. Psychometrika, 76: 537549. [Crossref], [PubMed], [Web of Science ®] [Google Scholar]) and target bifactor rotations (Reise, Moore, &; Maydeu-Olivares, 2011 Reise, S. P., Moore, T. M. and Maydeu-Olivares, A. 2011. Targeted bifactor rotations and assessing the impact of model violations on the parameters of unidimensional and bifactor models. Educational and Psychological Measurement, 71: 684711. [Crossref], [Web of Science ®] [Google Scholar]). Then I discuss limited- and full-information estimation approaches to confirmatory bifactor models that have emerged from the item response theory and factor analysis traditions, respectively. Comparison of the confirmatory bifactor model to alternative nested confirmatory models and establishing parameter invariance for the general factor also are discussed. Finally, important applications of bifactor models are reviewed. These applications demonstrate that bifactor modeling potentially provides a solid foundation for conceptualizing psychological constructs, constructing measures, and evaluating a measure's psychometric properties. However, some applications of the bifactor model may be limited due to its restrictive assumptions.  相似文献

In this article, the authors examined predictors of self-reported everyday memory failures using the Prospective and Retrospective Questionnaire (PRMQ; Smith, Della Sala, Logie, &; Maylor, 2000 Smith, G. V., Della Sala, S., Logie, R. H. and Maylor, E. A. M. 2000. Prospective and retrospective memory in normal ageing and dementia: A questionnaire study. Memory, 8: 311321. [Taylor &; Francis Online], [Web of Science ®] [Google Scholar]) in a population-based sample of older adults (age range = 60–90 years; N = 250). The results showed that a higher frequency of reported failures was associated with lower scores on the personality dimension of self-directedness as assessed by the Temperament and Character Inventory (TCI; Cloninger, Dragan, Svrakic, &; Przybeck, 1993 Cloninger, R. C., Dragan, M. S., Svrakic, D. M. and Przybeck, T. R. 1993. A psychobiological model of temperament and character. Archives of General Psychiatry, 50: 975990. [Crossref], [PubMed], [Web of Science ®] [Google Scholar]) and more depressive symptoms on the Center for Epidemiological Studies Depression Scale (CES-D; Radloff, 1977 Radloff, L. S. 1977. The CES-D scale: A self-report depression scale for research in the general population. Applied Psychological Measurement, 1: 385401. [Crossref], [Web of Science ®] [Google Scholar]). However, PRMQ scores showed no relationships with objective memory ability, as reflected by a series of retrospective memory measures and a measure of prospective memory. Neither were the PRMQ scales associated with general cognitive functioning as assessed by the Mini-Mental State Examination (MMSE; Folstein, Folstein, &; McHugh, 1977). Taken together, the results indicate that within the older population, self-reported memory as assessed by the PRMQ may reflect mood-state and personality factors rather than individual differences in memory and cognitive ability.  相似文献

Enhanced pitch perception and memory have been cited as evidence of a local processing bias in autism spectrum disorders (ASD). This bias is argued to account for enhanced perceptual functioning (Mottron &; Burack, 2001 Mottron, L. and Burack, J. A. 2001. “Enhanced perceptual functioning in the development of autism”. In The development of autism: Perspectives from theory to research, Edited by: Burack, J. A., Charman, T., Yirmiya, N. and Zelazo, P. R. 131147. Mahwah, NJ: Lawrence Erlbaum.  [Google Scholar]; Mottron, Dawson, Soulières, Hubert, &; Burack, 2006 Mottron, L., Dawson, M., Soulières, I., Hubert, B. and Burack, J. 2006. Enhanced perceptual functioning in autism: An update, and eight principles of autistic perception. Journal of Autism and Developmental Disorders, 36(1): 2743. doi:10.1007/s10803-005-0040-7[Crossref], [PubMed], [Web of Science ®] [Google Scholar]) and central coherence theories of ASD (Frith, 1989 Frith, U. 1989. Autism: Explaining the enigma, Oxford: United Kingdom: Blackwell.  [Google Scholar]; Happé &; Frith, 2006 Happé, F. and Frith, U. 2006. The weak coherence account: Detail-focused cognitive style in autism spectrum disorders. Journal of Autism and Developmental Disorders, 36(1): 525. doi:10.1007/s10803-005-0039-0[Crossref], [PubMed], [Web of Science ®] [Google Scholar]). A local processing bias confers a different cognitive style to individuals with ASD (Happé, 1999 Happé, F. 1999. Autism: Cognitive deficit or cognitive style?. Trends in Cognitive Sciences, 3(6): 216222. doi:10.1016/S1364-6613(99)01318-2[Crossref], [PubMed], [Web of Science ®] [Google Scholar]), which accounts in part for their good visuospatial and visuoconstructive skills. Here, we present analogues in the auditory domain, audiotemporal or audioconstructive processing, which we assess using a novel experimental task: a musical puzzle. This task evaluates the ability of individuals with ASD to process temporal sequences of musical events as well as various elements of musical structure and thus indexes their ability to employ a global processing style. Musical structures created and replicated by children and adolescents with ASD (10–19 years old) and typically developing children and adolescents (7–17 years old) were found to be similar in global coherence. Presenting a musical template for reference increased accuracy equally for both groups, with performance associated to performance IQ and short-term auditory memory. The overall pattern of performance was similar for both groups; some puzzles were easier than others and this was the case for both groups. Task performance was further found to be correlated with the ability to perceive musical emotions, more so for typically developing participants. Findings are discussed in light of the empathizing-systemizing theory of ASD (Baron-Cohen, 2009 Baron-Cohen, S. 2009. Autism: The Empathizing-Systemizing (E-S) Theory. Annals of the New York Academy of Sciences, 1156: 6880. doi:10.1111/j.1749-6632.2009.04467.x[Crossref], [PubMed], [Web of Science ®] [Google Scholar]) and the importance of describing the strengths of individuals with ASD (Happé, 1999 Happé, F. 1999. Autism: Cognitive deficit or cognitive style?. Trends in Cognitive Sciences, 3(6): 216222. doi:10.1016/S1364-6613(99)01318-2[Crossref], [PubMed], [Web of Science ®] [Google Scholar]; Heaton, 2009 Heaton, P. 2009.

Individual differences in processing information about a personal threat message about bisphenol A (BPA) risk were examined using the threat orientation model (Thompson &; Schlehofer, 2008 Thompson , S. C. , &; Schlehofer , M. M. ( 2008 ). Control, denial, and heightened sensitivity reactions to personal threat: Testing the generalizability of the threat orientation approach . Personality and Social Psychology Bulletin , 34 , 10701083 .[Crossref], [PubMed], [Web of Science ®] [Google Scholar]). Adults (N = 448) read a risk message concerning BPA in plastics. Threat orientations, intentions to protect oneself from BPA risk, and emotional and cognitive reactions to the message were measured. Individuals with different approaches to threat reached different conclusions about the message and used different information in that process. These findings suggest that consideration of individual differences could improve the predictive ability of existing theoretical models and the effectiveness of health and safety messages.  相似文献

The ability to deal with sources of conflict, that is, interference control, was evaluated in a group of 11 children with first episode Major Depression and a peer control group. To this end, the Eriksen and Schultz (1979 Eriksen, C. W. and Schulz, D. W. 1979. Information processing in visual search: A continuous flow conception and experimental results. Perception and Psychophysics, 25: 249263. [Crossref], [PubMed], [Web of Science ®] [Google Scholar]) task was used. Here, the participant is presented with a stimulus that simultaneously activates two conflicting response channels: One response is activated by the instructions, whereas the other response is activated by elements in the array that strongly invite an alternative — yet incorrect — response. Findings provided no evidence for an undisturbed interference control nor impaired overall processing speed in children with first episode Major Depression.  相似文献

Two experiments examined the effect of film music on the narrative persuasion. In Experiment 1, participants viewed a short film with its original musical soundtrack or with soundtrack muted. In Experiment 2, musical soundtrack was added to a film that was originally produced without music. Findings indicated that participants reported greater transportation into the film and greater agreement with film-relevant beliefs when soundtrack was presented but only when music was congruent with the film's affective tone. In support of the transportation-imagery model (Green &; Brock, 2000 Green , M. C. , &; Brock , T. C. ( 2000 ). The role of transportation in the persuasiveness of public narratives . Journal of Personality and Social Psychology , 79 , 701721 .[Crossref], [PubMed], [Web of Science ®] [Google Scholar]), the effect of film music on beliefs was mediated by transportation into the film.  相似文献

We reconstruct recent work on macrosocial stress (Chou, Parmar, &; Galinsky, 2016 Chou, E. Y., Parmar, B. L., &; Galinsky, A. D. (2016). Economic insecurity increases physical pain. Psychological Science, 27, 434454. doi:10.1177/0956797615625640[Crossref], [Web of Science ®] [Google Scholar]) as if it were an instance of a research strategy that tests point-alternative hypotheses within a full-fledged research program. Because this strategy is free of various deficits that beset dominant strategies (e.g., meta-analysis, Bayes factor analysis), our article demonstrates one way in which the confidence crisis may be overcome.  相似文献

This study examined the role of intimate partner victimization in mediating the relationship between childhood sexual abuse and adulthood parenting in a community sample of mothers reliant on public assistance (N = 483). Baron and Kenny's (1986 Baron, R. M. and Kenny, D. A. 1986. The moderator–mediator variable distinction in social psychological research: Conceptual, strategic, and statistical considerations. Journal of Personality and Social Psychology, 51: 11731182. [Crossref], [PubMed], [Web of Science ®] [Google Scholar]) method for establishing mediation was used to address this question. A recent history of intimate partner violence mediated the relationship between childhood sexual abuse and psychological aggression; however, a lifetime history of intimate partner violence did not. Depressive symptomatology was found to mediate the relationship between childhood sexual abuse and parental warmth. The impact of childhood sexual abuse on corporal punishment was indirect through its association with childhood physical abuse and witnessing domestic violence. Implications for research, theory development, and practice are provided.  相似文献

Pictures are widely used as stimuli in implicit motive tests. Hybrid forms of such tests present pictures and declarative statements underneath pictures. Some authors have argued that explicitly declaring agreement with motive-related statements presented underneath pictures might shift the validity of such tests from capturing less implicit motives to more explicit motives. If that is the case, pictures as elicitors of implicit motives might become less relevant. Adopting the views on validity presented by Borsboom, Mellenbergh, and van Heerden (2004 Borsboom, D., Mellenbergh, G. J., &; van Heerden, J. (2004). The concept of validity. Psychological Review, 111, 10611071. doi:10.1037/0033-295X.111.4.1061[Crossref], [PubMed], [Web of Science ®] [Google Scholar]) and Bornstein (2011 Bornstein, R. F. (2011). Toward a process-focused model of test score validity: Improving psychological assessment in science and practice. Psychological Assessment, 23, 532544. doi:10.1037/a0022402[Crossref], [PubMed], [Web of Science ®] [Google Scholar]), as well as item generation theory, we investigated whether the availability of pictures in hybrid motive tests causally affects test scores. To this end, we administered the Multi-Motive Grid (MMG; Sokolowski, Schmalt, Langens, &; Puca, 2000 Sokolowski, K., Schmalt, H.-D., Langens, T. A., &; Puca, R. M. (2000). Assessing achievement, affiliation, and power motives all at once: The Multi-Motive-Grid (MMG). Journal of Personality Assessment, 74, 126145. doi:10.1207/S15327752JPA740109[Taylor &; Francis Online], [Web of Science ®] [Google Scholar]), as an example of a hybrid motive test, either with or without pictures to 108 participants. Results revealed that the availability of pictures had no effect on 3 out of 6 test scores. Furthermore, eliminating pictures had only inconsistent effects on correlations with a test of explicit motives. We conclude that pictures might not unanimously elicit motives in implicit motive tests that use declarative statements as response options.  相似文献

The effect of lexicality and stimulus length was studied in 32 third- and fourth-grade Italian dyslexics and in 86 age-matched controls. A visual lexical decision task was used. As proposed by Faust et al. (1999) Faust, M. E., Balota, D. A., Spieler, D. H. and Ferraro, F. R. 1999. Individual differences in information-processing rate and amount: Implications for group differences in response latency. Psychological Bulletin, 125: 777799. [INFOTRIEVE][CROSSREF][CSA][Crossref], [PubMed], [Web of Science ®] [Google Scholar], the results were analyzed in terms of raw reaction time (RT) data and using the z-score transformation to control for the presence of overadditivity effects. In terms of RTs, dyslexics showed a larger difference between words and nonwords (lexicality effect) and between short and long stimuli (length effect) than proficient readers. When data were transformed into z scores, only the group by length interaction remained significant while that with lexicality vanished. This pattern indicates that stimulus length has a specific role in Italian dyslexics’ reading deficit; in contrast, slowness in responding to nonwords was not specific but was interpreted as one aspect of dyslexics’ general inability to deal with alphabetical material (overadditivity effect).  相似文献

Previous research has shown the importance of quality of life (QOL) for critical organizational outcomes such as the retention of U.S. Navy personnel (Wilcove, Schwerin, &; Wolosin, 2003 Wilcove, G., Schwerin, M. and Wolosin, D. 2003. An exploratory model of quality of life in the U.S. Navy.. Military Psychology, 15(2): 133152. [Taylor &; Francis Online], [Web of Science ®] [Google Scholar]) and Marines (Hindelang, Schwerin, &; Farmer, 2004 Hindelang, R. L., Schwerin, M. J. and Farmer, W. L. 2004. Quality of life (QOL) in the U.S. Marine Corps: The validation of a QOL model for predicting reenlistment intentions.. Military Psychology, 16(2): 115134. [Taylor &; Francis Online], [Web of Science ®] [Google Scholar]). These studies employed a life domains approach addressing a full range of work and non-work life needs as well as specific aspects of each life domain. In contrast, most other research exploring outcomes critical to military organizations focused only on work life needs of personnel (e.g., job satisfaction, organizational commitment, command climate). This study extends previous research by (a) including both performance and career-continuance plans of personnel as outcomes of interest, (b) exploring the contribution of an additional life need—spiritual well-being—to the measurement of QOL, and (c) examining changes in perceptions of QOL over time between 1999 and 2002 among U.S. Navy personnel. Implications of findings to military personnel, families, and manpower and personnel policy as well as future directions for research are discussed.  相似文献

This work examines ways to make the best use of limited resources when selecting individuals to follow up in a longitudinal study estimating causal effects. In the setting under consideration, covariate information is available for all individuals but outcomes have not yet been collected and may be expensive to gather, and thus only a subset of the comparison participants are followed. Expressions in Rubin and Thomas (1996) Rubin, D. B. and Thomas, N. 1996. Matching using estimated propensity scores, relating theory to practice.. Biometrics, 52: 249264. [Crossref], [PubMed], [Web of Science ®] [Google Scholar] show the benefits that can be obtained, in terms of reduced bias and variance of the estimated treatment effect, of selecting comparison individuals well matched to those in the treated group compared with a random sample of comparison individuals. We primarily consider nonexperimental settings but also consider implications for randomized trials. The methods are illustrated using data from the Johns Hopkins University Baltimore Prevention Program, which included data collection from age 6 to young adulthood of participants in an evaluation of 2 early elementary-school-based universal prevention programs.  相似文献

The current study used archival data to evaluate the fit of six latent variable models, originally generated by Donders (1999) Donders. 1999. Structural analysis of the California Verbal Learning Test—Children's Version in the standardization sample. Developmental Neuropsychology, 15(3): 395406. [CSA][Taylor &; Francis Online], [Web of Science ®] [Google Scholar], for the California Verbal Learning Test-Children's Version (CVLT-C; Delis, Kramer, Kaplan, &; Ober, 1994 Delis, D. C., Kramer, J. H., Kaplan, E. and Ober, B. A. 1994. California Verbal Learning Test—Children's Version, San Antonio, TX: Psychological Corporation.  [Google Scholar]) in a large (N = 289) sample of pediatric epilepsy cases presenting at three tertiary treatment centers. Using confirmatory factor analysis, we found that a model including factors of Attention Span, Learning Efficiency, Free Delayed Recall, Cued Delayed Recall, and Inaccurate Recall demonstrated the best relative fit for our data. These findings are consistent with those reported by Donders (1999) Donders. 1999. Structural analysis of the California Verbal Learning Test—Children's Version in the standardization sample. Developmental Neuropsychology, 15(3): 395406. [CSA][Taylor &; Francis Online], [Web of Science ®] [Google Scholar] in his reanalysis of the CVLT-C standardization sample data, supporting the validity of this factorial model in pediatric epilepsy populations.  相似文献
