Wide-ranging semantic flexibility is often considered a magic cure for contextualism to account for all kinds of troubling data. In particular, it seems to offer a way to account for our intuitions regarding embedded perspectival sentences. As has been pointed out by Lasersohn [2009. “Relative Truth, Speaker Commitment, and Control of Implicit Arguments.” Synthese 166 (2): 359â374], however, the semantic flexibility does not present a remedy for all kinds of embeddings. In particular, it seems ineffective when it comes to embeddings under operators with truth evaluative adverbs such as ‘correctly believes that’ and ‘incorrectly believes that’ and under factive verbs. This paper takes a closer look at the problematic embedding data with respect to predicates of personal taste. It argues that there is indeed no semantic solution for contextualism but a pragmatic way out. 相似文献

Confounding present in observational data impede community psychologists’ ability to draw causal inferences. This paper describes propensity score methods as a conceptually straightforward approach to drawing causal inferences from observational data. A step-by-step demonstration of three propensity score methods—weighting, matching, and subclassification—is presented in the context of an empirical examination of the causal effect of preschool experiences (Head Start vs. parental care) on reading development in kindergarten. Although the unadjusted population estimate indicated that children with parental care had substantially higher reading scores than children who attended Head Start, all propensity score adjustments reduce the size of this overall causal effect by more than half. The causal effect was also defined and estimated among children who attended Head Start. Results provide no evidence for improved reading if those children had instead received parental care. We carefully define different causal effects and discuss their respective policy implications, summarize advantages and limitations of each propensity score method, and provide SAS and R syntax so that community psychologists may conduct causal inference in their own research. 相似文献

RESUMENEn esta entrevista Bem comenta la relación entre sus aportaciones científicas -el estudio psicológico de los roles sexuales a nivel tanto instrumental como conceptual- y su compromiso personal a favor de unas relaciones más igualitarias entre las personas, ofreciendo una visión comprehensiva de su evolución profesional y personal y repasando las cuestiones más interesantes de la etapa de estudios sobre androginia (1974–1979) y de su actual enfoque cognitivo. Tras comenzar explicando su formación y trayectoria científica, así como las motivaciones que han guiado su trabajo, la autora realiza un análisis crítico del Bem Sex Role Inventory (BSRI). Seguidamente profundiza en diversos aspectos del concepto “androginia” acuñado por ella y explica las razones por las que a partir de 1979 los sujetos tipificados sexualmente se convierten en el blanco de su teoría sobre el esquema cognitivo del género, así como la caracterización de los conceptos masculinidad y/o feminidad como constructos cognitivos. La entrevista finaliza con algunas alusiones acerca de cómo educar a los niños de una “forma no esquemática” con respecto al género y señalando sus preocupaciones científicas más recientes en torno al concepto de género en los niños. 相似文献

ABSTRACTEvaluative conditioning (EC) is proposed as a mechanism of automatic preference acquisition in dual-process theories of attitudes (Gawronski, B., & Bodenhausen, G. V. (2006). Associative and propositional processes in evaluation: An integrative review of implicit and explicit attitude change. Psychological Bulletin, 132(5), 692–731. doi:10.1037/0033-2909.132.5.692). Evidence for the automaticity of EC comes from studies claiming EC effects for subliminally presented stimuli. An impression-formation study showed a selective influence of briefly presented primes on implicitly measured attitudes, whereas supraliminally presented behavioural information about the target person was reflected in explicit ratings (Rydell, R. J., McConnell, A. R., Mackie, D. M., & Strain, L. M. (2006). Of two minds forming and changing valence-inconsistent implicit and explicit attitudes. Psychological Science, 17(11), 954–958. doi:10.1111/j.1467-9280.2006.01811.x) This finding is considered one of the strongest pieces of evidence for dual process theories (Sweldens, S., Corneille, O., & Yzerbyt, V. (2014). The role of awareness in attitude formation through evaluative conditioning. Personality and Social Psychology Review, 18(2), 187–209. doi:10.1177/1088868314527832), and it is therefore crucial to assess its reliability and robustness. The present study presents two registered replications of the Rydell et al. (2006) study. In contrast to the original findings, the implicit measures did not reflect the valence of the subliminal primes in both studies. 相似文献

We tested direct, indirect, and behavioural measures of fear of spiders under neutral instructions, and when participants were asked to fake high and low fear of spiders. Our findings indicate that the Approach Avoidance Task (AAT) was the only measure that could be faked in one of the faking conditions only. We also assessed how easily faked results could be detected on each measure for different diagnostic criteria. The direct and behavioural measures showed good performance for all criteria. The AAT performed comparably only for a conservative criterion, when detecting fakers is less important than correctly labelling non-fakers. 相似文献

When there is an established strategy to solve a problem, we often approach the problem with a mindset that makes us blind for more efficient solutions. We examined the role of affect in overcoming such blinding effects of mindsets. As positive affect is known to broaden and negative affect to narrow thought–action repertoires, we speculated that positive affect facilitates and negative affect impedes the overcoming of a current mindset. To induce a mindset, participants initially solved 60 similar problems which were only solvable using the same complex strategy. After a short break in which positive or negative affect was induced, participants continued to work on the problems. Critically, there now was an additional simple way to solve the problems. Participants experiencing positive affect were more likely to detect the simple solution than participants experiencing negative affect. These findings reveal that affect modulates how much we are constrained by current mindsets. 相似文献

Current interpretation of the object retrieval task (Diamond, 1990) as an infant assessment of response inhibition requires evidence that younger infants make more ineffective attempts to retrieve toys through clear barriers. On two 30-second trials, infants (9 or 11 months of age) saw an inaccessible toy in the front or back of a clear box. The location of the infants touches corresponded with the toy's location and, on the second trial, the younger infants touched the box more. In previous research nonhuman primates with orbital-frontal, but not dorsa-lateral, lesions also made ineffective barrier touches. The current developmental decreases in barrier touches may selectively tap developmental increases in inhibitory control supported by the developing orbital-frontal cortex. 相似文献

Recently, we derived a generalized model for isotropic as well as anisotropic crystal lattice systems of arbitrary Poisson's ratio within the framework of the continuum phase-field crystal (PFC) approach [R. Prieler, J. Hubert, D. Li, B. Verleye, R. Haberkern, H. Emmerich, J. Phys.: Condens. Matter 21 (2009) p.464110] and showed how its parameters can be derived from classical density functional theory [M.A. Choudhary, D. Li, H. Emmerich and H. Löwen, J. Phys.: Condens. Matter 23 (2011) p.265005]. Here, we present a general procedure to model anisotropic material systems of arbitrary Poisson's ratios. In that way we can for the first time identify PFC solutions of arbitrary Poisson's ratios and thereby extend the applicability of the PFC method to a larger class of material systems. 相似文献

We examined memory for pictures and words in middle-age (45–59 years), young-old (60–74 years), old-old (75–89 years), and the oldest-old adults (90–97 years) in the Louisiana Healthy Aging Study. Stimulus items were presented and retention was tested in a blocked order where half of the participants studied 16 simple line drawings and the other half studied matching words during acquisition. Free recall and recognition followed. In the next acquisition/test block a new set of items was used where the stimulus format was changed relative to the first block. Results yielded pictorial superiority effects in both retention measures for all age groups. Follow-up analyses of clustering in free recall revealed that a greater number of categories were accessed (which reflects participants’ retrieval plan) and more items were recalled per category (which reflects participants’ encoding strategy) when pictures served as stimuli compared to words. Cognitive status and working memory span were correlated with picture and word recall. Regression analyses confirmed that these individual difference variables accounted for significant age-related variance in recall. These data strongly suggest that the oldest-old can utilise nonverbal memory codes to support long-term retention as effectively as do younger adults. 相似文献

Marginally perceptible prototypes as primes lead to slowed reactions to related category exemplars as compared to unrelated ones. This at first glance counterintuitive finding has been interpreted as evidence for a particular mechanism of lateral inhibition, namely the centre surround inhibition mechanism. We investigated the semantic surround of category labels by experimentally manipulating the prototypicality of stimuli. Participants first learned two new categories of fantasy creatures in a 5-day-long learning phase before they worked through a semantic priming task with the category prototypes as primes and category exemplars as targets. For high-prototypical targets we observed benefit effects from related primes, whereas for low-prototypical targets we observed cost effects. The results define when the centre surround inhibition mechanism is applied, and furthermore might explain why previous studies with word stimuli (i.e., material that prevents experimental manipulation of prototypicality) observed mixed results concerning the prototypicality of targets. 相似文献
