Implicit measures have revealed that cognitive representations of familiar individuals share associations with self-concept; however, this has yet to be established for novel individuals. We examined how self-similarity affects representation of information learned about new individuals. A novel version of the implicit association test (IAT), the self-similarity IAT, was developed to estimate the extent to which cognitive representations of new self-similar and self-dissimilar individuals are associated with self-representation. Categorization was faster when the self-similar individual was paired with self, not only for trait words related to the novel individuals, but also for unrelated demographic information pertaining only to self. This provides the first evidence using an implicit task that self-similarity may act as a heuristic for creating representations of new individuals. 相似文献

There exists a dearth of literature on the content, research method and research design trends of dissertations in education. Within one large subfield of education (i.e. counsellor education), an online and full-text archive of dissertations has become available. This archive contains over 200 dissertations produced in Oregon State University’s Counselling Academic Unit from 1947 to 2014. Research questions concerning decadal differences in content, research method and research design were examined empirically. No decadal differences were discovered in the three aforementioned areas. Reasons for these findings were discussed. 相似文献

Availability of Alternatives and the Processing of Scalar Implicatures: A Visual World Eye‐Tracking Study 下载免费PDF全文
Two visual world experiments investigated the processing of the implicature associated with some using a “gumball paradigm.” On each trial, participants saw an image of a gumball machine with an upper chamber with orange and blue gumballs and an empty lower chamber. Gumballs dropped to the lower chamber, creating a contrast between a partitioned set of gumballs of one color and an unpartitioned set of the other. Participants then evaluated spoken statements, such as “You got some of the blue gumballs.” Experiment 1 investigated the time course of the pragmatic enrichment from some to not all when the only utterance alternatives available to refer to the different sets were some and all. In Experiment 2, the number terms two, three, four, and five were also included in the set of alternatives. Scalar implicatures were delayed relative to the interpretation of literal statements with all only when number terms were available. The results are interpreted as evidence for a constraint‐based account of scalar implicature processing. 相似文献

The Behavior Rating Inventory of Executive Functioning (BRIEF) is a parent report measure designed to assess executive skills in everyday life. The present study employed a confirmatory factor analysis (CFA) to evaluate three alternative models of the factor structure of the BRIEF. Given the executive functioning difficulties that commonly co-occur with attention-deficit/hyperactivity disorder (ADHD), the participants included 181 children and adolescents with a diagnosis of ADHD. The results indicated that an oblique two-factor model, in which the Monitor subscale loaded on both factors (i.e., Behavioral Regulation, Metacognition) and measurement errors for the Monitor and Inhibit subscales were allowed to correlate, provided an acceptable goodness-of-fit to the data. This two-factor model is consistent with previous research indicating that the Monitor subscale reflects two dimensions (i.e., monitoring of task-related activities and monitoring of personal behavioral activities) and thus loads on multiple factors. These findings support the clinical relevance of the BRIEF in children with ADHD, as well as the multidimensional nature of executive functioning. 相似文献

In this paper, we use behavioural methods and event-related potentials (ERPs) to explore the relations between informational and instantiated features, as well as the relation between feature abstraction and rule type. Participants are trained to categorize two species of fictitious animals and then identify perceptually novel exemplars. Critically, two groups are given a perfectly predictive counting rule that, according to Hannah and Brooks (2009. Featuring familiarity: How a familiar feature instantiation influences categorization. Canadian Journal of Experimental Psychology/Revue Canadienne de Psychologie Expérimentale, 63, 263–275. Retrieved from http://doi.org/10.1037/a0017919), should orient them to using abstract informational features when categorizing the novel transfer items. A third group is taught a feature list rule, which should orient them to using detailed instantiated features. One counting-rule group were taught their rule before any exposure to the actual stimuli, and the other immediately after training, having learned the instantiations first. The feature-list group were also taught their rule after training. The ERP results suggest that at test, the two counting-rule groups processed items differently, despite their identical rule. This not only supports the distinction that informational and instantiated features are qualitatively different feature representations, but also implies that rules can readily operate over concrete inputs, in contradiction to traditional approaches that assume that rules necessarily act on abstract inputs. 相似文献

The study examined two questions: (1) do the greater phonological awareness skills of billinguals affect reading performance;
(2) to what extent do the orthographic characteristics of a language influence reading performance and how does this interact
with the effects of phonological awareness. We estimated phonological metalinguistic abilities and reading measures in three
groups of first graders: monolingual Hebrew speakers, bilingual Russian–Hebrew speakers, and Arabic-speaking children. We
found that language experience affects phonological awareness, as both Russian–Hebrew bilinguals and the Arabic speakers achieved
higher scores on metalinguistic tests than Hebrew speakers. Orthography affected reading measures and their correlation with
phonological abilitites. Children reading Hebrew showed better text reading ability and significant correlations between phonological
awareness and reading scores. Children reading Arabic showed a slight advantage in single word and nonword reading over the
two Hebrew reading groups, and very weak relationships between phonological abilities and reading performance. We conclude
that native Arabic speakers have more difficulty in processing Arabic orthography than Hebrew monolinguals and bilinguals
have in processing Hebrew orthography, and suggest that this is due to the additional visual complexity of Arabic orthography. 相似文献

Although violence and homicide are more prevalent in Colombia, South America than the US, the role of psychosocial factors
in the violent behavior of Colombian adolescents remains unclear. The aim of this longitudinal study was to examine the interrelation
of domains of personality, familial, peer, and ecological variables associated with violence in a community sample of adolescents
from various self-reported ethnic groups in Colombia. The sample consisted of 1,151 male adolescents selected from three Colombian
cities. The participants were surveyed using structured interviews at two points in time over a 2-year interval. Data were
collected concerning adolescent personal attributes, family characteristics, peer, and ecological factors, including drug
availability and the prevalence of violence in the community. The dependent variable was the self-reported frequency of the
adolescent’s violent behavior. The results supported a model in which violent behavior was correlated independently over time
with a number of risk factors from several domains. Evidence for the hypothesized mediated effects of the familial monitoring
and bonding domain, the peer domain, the ecological domain, and prior victimization related to personal attributes and contemporaneous
violence and the adolescent’s violent behavior 2 years later was also found. The findings suggest the use of specific intervention
procedures with adolescents to prevent their subsequent violent behavior. 相似文献
