Accumulated recent research suggests that prior knowledge of multiple languages leads to advantages in learning additional languages. In the current article, we review studies examining potential differences between monolingual and multilingual speakers in novel language learning in an effort to uncover the cognitive mechanisms that underlie such differences. We examine the multilingual advantage in children and adults, across a wide array of languages and learner populations. The majority of this literature focused on vocabulary learning, but studies that address phonology, grammar, and literacy learning are also discussed to provide a comprehensive picture of the way in which multilingualism affects novel language learning. Our synthesis indicates two avenues to the multilingual advantage including direct transfer of prior knowledge and prior skills as well as indirect influences that result from multilingual background and include more general changes to the cognitive-linguistic system. Finally, we highlight topics that are in need of future systematic research. 相似文献

In this paper I defend Kant’s Incorporation Thesis, which holds that we must “incorporate” our incentives into our maxims
if we are to act on them. I see this as a thesis about what is necessary for a human being to make the transition from ‘having
a desire’ to ‘acting on it’. As such, I consider the widely held view that ‘having a desire’ involves being focused on the
world, and not on ourselves or on the desire. I try to show how this view is connected with a denial of any deep distinction
between reason and inclination. I then argue for an alternative view of what ‘having a desire’ involves, one according to
which it involves being focused both on the world and on ourselves. I show how this view fits naturally with the Kantian distinction
between reason and inclination, accounts for independent intuitions about ‘having a desire’, and supports the Incorporation
Thesis. I then make some further suggestions about how we might conceive of the object of incorporation. 相似文献

The authors outline a cognitive and computational account of causal learning in children. They propose that children use specialized cognitive systems that allow them to recover an accurate "causal map" of the world: an abstract, coherent, learned representation of the causal relations among events. This kind of knowledge can be perspicuously understood in terms of the formalism of directed graphical causal models, or Bayes nets. Children's causal learning and inference may involve computations similar to those for learning causal Bayes nets and for predicting with them. Experimental results suggest that 2- to 4-year-old children construct new causal maps and that their learning is consistent with the Bayes net formalism. 相似文献

Most models of visual word recognition in alphabetic orthographies assume that words are lexically organized according to orthographic similarity. Support for this is provided by form-priming experiments that demonstrate robust facilitation when primes and targets share similar sequences of letters. The authors examined form-orthographic priming effects in Hebrew, Arabic, and English. Hebrew and Arabic have an alphabetic writing system but a Semitic morphological structure. Hebrew morphemic units are composed of noncontiguous phonemic (and letter) sequences in a given word. Results demonstrate that form-priming effects in Hebrew or Arabic are unreliable, whereas morphological priming effects with minimal letter overlap are robust. Hebrew bilingual subjects, by contrast, showed robust form-priming effects with English material, suggesting that Semitic words are lexically organized by morphological rather than orthographic principles. The authors conclude that morphology can constrain lexical organization even in alphabetic orthographies and that visual processing of words is first determined by morphological characteristics. 相似文献

The success of human culture depends on early emerging mechanisms of social learning, which include the ability to acquire opaque cultural knowledge through faithful imitation, as well as the ability to advance culture through flexible discovery of new means to goal attainment. This study explores whether this mixture of faithful imitation and goal emulation is based in part on individual differences which emerge early in ontogeny. Experimental measurements and parental reports were collected for a group of 2‐year‐old children (N = 48, age = 23–32 months) on their imitative behavior as well as other aspects of cognitive and social development. Results revealed individual differences in children's imitative behavior across trials and tasks which were best characterized by a model that included two behavioral routines; one corresponding to faithful imitation, and one to goal emulation. Moreover, individual differences in faithful imitation and goal emulation were correlated with individual differences in theory of mind, prosocial behavior, and temperament. These findings were discussed in terms of their implications for understanding the mechanisms of social learning, ontogeny of cumulative culture, and the benefit of analyzing individual differences for developmental experiments. 相似文献

This review examines later life family support for adults with developmental disabilities from a life course perspective that takes into account social trends and changes in service patterns and in attitudes of families. Key issues addressed include: (1) trends affecting family caregiving, (2) health and social outcomes of life-long caregiving, (3) support needs of families, (4) family support policies and practices, and (5) recommendations for a research and policy agenda. Research examining outcomes of life-long caregiving has shown that most families adapt well to having a family member with disabilities. However, some families are at risk for poorer physical and mental health outcomes. These include cultural minorities and families of adults with behavioral challenges. Caregiving does seem to have a negative impact on maternal employment and family income as mothers often give up or cut back on employment to care for a child with developmental disabilities, who is more likely to continue living in the family home throughout adulthood than other adult children. Federal and state initiatives are addressing issues of family support through both the developmental disabilities and aging service systems. 相似文献

This study examines preschoolers' causal assumptions about spatial contiguity and how these assumptions interact with new evidence in the form of conditional probabilities. Preschoolers saw a toy that activated in the presence of certain objects. Children were shown evidence for the toy's activation rule in the form of patterns of probability: The toy was more likely to activate either when objects made contact with its surface (on condition) or when objects were several inches above its surface (over condition). In Experiment 1, 61 three-year-olds saw a deterministic activation rule. In Experiments 2 and 3, 48 four-year-olds saw an activation rule that was probabilistic. In Experiment 4, 30 four-year-olds saw a screening-off pattern of activation. In all 4 experiments, children used new evidence in the form of patterns of probability to make accurate causal inferences, even in the face of conflicting prior beliefs about spatial contiguity. However, children were more likely to make correct inferences when causes were spatially contiguous, particularly when faced with ambiguous evidence. 相似文献

Reactions to tokenism: The role of individual characteristics in shaping responses to token decisions 下载免费PDF全文
When only a handful of members from a disadvantaged group occupy positions of power, they are considered tokens. Previous research suggests that observers tend to consider tokenism as an egalitarian practice. Given its ambiguous nature, we hypothesized that reactions to tokenism would be shaped by individuals' sensitivity to inequality. In Study 1, we showed that women (vs. men) and individuals low (vs. high) on social dominance orientation differentiated more between a token and an egalitarian decision in the context of gender‐related practices. Similar findings were observed in Study 2, which involved gender and feminist identification as independent variables. Additional support, particularly for the role of social dominance orientation, was found in Study 3, which involved an ethnic token. Together, results demonstrate the role of individuals' chronic sensitivity to inequality in shaping their reactions to token practices. Theoretical and practical implications regarding the effect of tokenism on individuals' evaluations and responses to inequality are discussed. Copyright © 2016 John Wiley & Sons, Ltd. 相似文献
