This study investigates the contribution of frequency learning and teleological reasoning to action prediction in 9-month-old infants and adults. Participants observed how an agent repeatedly walked to a goal while taking the longer of 2 possible paths, as the shorter and more efficient path was impassable. In the subsequent test phase, both paths were passable. In the 1st test trial, infants and adults anticipated the agent to take the longer path. Unlike adults, infants kept anticipating movements to the longer path even after observing that the agent now took the more efficient path, indicating that the frequency of previous observations dominates action prediction. These results provide evidence, contrary to existing claims in the developmental literature, that frequency learning underlies action prediction in infancy, whereas teleological reasoning might gain importance later on in life. 相似文献

Posttraumatic stress disorder (PTSD) is effectively treated with eye movement desensitization and reprocessing (EMDR) with patients making eye movements during recall of traumatic memories. Many therapists have replaced eye movements with bilateral beeps, but there are no data on the effects of beeps. Experimental studies suggest that eye movements may be beneficial because they tax working memory, especially the central executive component, but the presence/degree of taxation has not been assessed directly. Using discrimination Reaction Time (RT) tasks, we found that eye movements slow down RTs to auditive cues (experiment I), but binaural beeps do not slow down RTs to visual cues (experiment II). In an arguably more sensitive “Random Interval Repetition” task using tactile stimulation, working memory taxation of beeps and eye movements were directly compared. RTs slowed down during beeps, but the effects were much stronger for eye movements (experiment III). The same pattern was observed in a memory experiment with healthy volunteers (experiment IV): vividness of negative memories was reduced after both beeps and eye movements, but effects were larger for eye movements. Findings support a working memory account of EMDR and suggest that effects of beeps on negative memories are inferior to those of eye movements. 相似文献

Toril Moi has argued that recent deconstructive challenges to the concept of gender and to the viability of the sex/gender distinction have brought feminist and queer theory to a place of increasing theoretical abstraction. She suggests that we should abandon the category of gender once and for all, because it is founded on a nature–culture distinction and it tends incorrigibly to essentialize women's lives. Moi argues that feminist and queer theories should replace the concept of gender with a concept of the lived body derived from existential phenomenology. In this essay I take up and develop this suggestion, and argue that there are several advantages that a category of the lived body has over a category of gender for feminist and queer theories: (1) no nature–culture distinction is necessary but the body can be described as historically and socially specific; (2) it is not necessary to break out a gendered and "raced" part of identity with this category; (3) differences of sexual desire can be described without recourse to an "inner core" of identity or "sexual orientation." I go on to argue, however, that it is important to retain a concept of gender for a theoretical purpose beyond that which Moi and those she criticizes conceive. In recent years feminist and queer theories have tended to conceive their theorizing as restricted to identity and subjectivity. How large scale social structures differentially position people in relations of privilege and disadvantage has been ignored, relatively. This essay argues then that theorizing structural processes and inequalities is crucial, and that a concept of gender is important for such theorizing. I propose three aspects of gendered social structure that are irreducible to one another: (1) a sexual division of labor (2) normative heterosexuality, and (3) hierarchies of power. In each case I illustrate the social theoretical work these categorizations of gendered structure can and should do. 相似文献

Hebrew constrains the occurrence of identical consonants in its roots: Identical consonants are acceptable root finally (e.g., skk), but not root initially (e.g., kks). Speakers' ability to freely generalize this constraint to novel phonemes (Berent, Marcus, Shimron, & Gafos, 2002) suggests that they represent segment identity-a relation among mental variables. An alternative account attributes the restriction on identical phonemes to their feature similarity, captured by either the number of shared features or their statistical frequency. The similarity account predicts that roots with partially similar consonants (e.g., sgk) should be at least as acceptable as roots with fully identical consonants (e.g., skk), and each of these roots should be less acceptable than dissimilar controls (e.g., gdn). Contrary to these predictions, three lexical decision experiments demonstrate that full identity is more acceptable than partial similarity and (in some cases) controls. Speakers' sensitivity to consonant identity suggests that linguistic competence, in general, and phonology, in particular, encompass a computational mechanism that operates over variables. This conclusion is consistent with linguistic accounts that postulate a symbolic grammatical component that is irreducible to the statistical properties of the lexicon. 相似文献

Electroencephalogram (EEG) alpha (8-12 Hz) asymmetries were collected from the mid-frontal and central regions during presleep wakefulness and Stage 1, Stage 2, and rapid eye movement (REM) sleep in 11 healthy right-handed participants who were free of psychiatric, neurological, and sleep problems. The authors found significant correlations between presleep wakefulness and different stages of sleep in the frontal, but not central, EEG alpha asymmetry measure. The strongest correlation was between presleep waking and REM sleep, replicating and extending relation earlier work to a normal population. The high degree of association between presleep waking and REM sleep may be a result of high cortical activation common to these states and may reflect a predisposition to different styles of emotional reactivity. 相似文献

Recently there has been growing interest among psychologists in human performance on the Euclidean traveling salesperson problem (E-TSP). A debate has been initiated on what strategy people use in solving visually presented E-TSP instances. The most prominent hypothesis is the convex-hull hypothesis, originally proposed by MacGregor and Ormerod (1996). We argue that, in the literature so far, there is no evidence for this hypothesis. Alternatively we propose and motivate the hypothesis that people aim at avoiding crossings. 相似文献

Bad but bold: Ambivalent attitudes toward men predict gender inequality in 16 nations 总被引:4,自引:0,他引:4

A 16-nation study involving 8,360 participants revealed that hostile and benevolent attitudes toward men, assessed by the Ambivalence Toward Men Inventory (P. Click & S.T. Fiske, 1999), were (a) reliably measured across cultures, (b) positively correlated (for men and women, within samples and across nations) with each other and with hostile and benevolent sexism toward women (Ambivalent Sexism Inventory, P. Click & S.T. Fiske, 1996), and (c) negatively correlated with gender equality in cross-national comparisons. Stereotype measures indicated that men were viewed as having less positively valenced but more powerful traits than women. The authors argue that hostile as well as benevolent attitudes toward men reflect and support gender inequality by characterizing men as being designed for dominance. 相似文献
