Bilingualism, aging, and cognitive control: evidence from the Simon task

Previous work has shown that bilingualism is associated with more effective controlled processing in children; the assumption is that the constant management of 2 competing languages enhances executive functions (E. Bialystok, 2001). The present research attempted to determine whether this bilingual advantage persists for adults and whether bilingualism attenuates the negative effects of aging on cognitive control in older adults. Three studies are reported that compared the performance of monolingual and bilingual middle-aged and older adults on the Simon task. Bilingualism was associated with smaller Simon effect costs for both age groups; bilingual participants also responded more rapidly to conditions that placed greater demands on working memory. In all cases the bilingual advantage was greater for older participants. It appears, therefore, that controlled processing is carried out more effectively by bilinguals and that bilingualism helps to offset age-related losses in certain executive processes.     

Physical and cognitive dimensions in stimulus comparison

Two experiments were carried out using a same-different task with sets of four stimuli varying orthogonally in three dimensions. Sameness was defined by each of the three dimensions in turn, as well as by physical identity. Two types of dimensions, physical and cognitive, were studied. In Experiment 1, the numerals 6, 10, VI, and X, which vary in Length, System, and Name, were used. With simultaneous presentation, order of difficulty was from the physical dimension of Length to the cognitive dimension of Name. While overall difficulty was related to dimensional discriminability, internal evidence suggested that Name was not a dimension in the same sense as Length is, and that some stimulus pairs were simply easier to process than others, regardless of the response required (e.g., short stimulus pairs and Arabic numerals). With sequential presentation, Name was processed as fast as System, due largely to the fact that much faster responding occurred when an Arabic numeral was the second stimulus. Thus, with sequential presentation, Name provides a processing mechanism not provided by physical dimensions. In Experiment 2, the numerals 3, 4, 6, and 7, which vary in Magnitude, Oddness, and Curvilinearity, were used. The cognitive dimension of Magnitude was pro cessed most rapidly, and numerical distance between pairs of numbers dominated the results for “same” responses, regardless of the sameness rule used. Again, evidence was found for fast processing of some stimulus pairs (e.g., 3 4), regardless of the response required. Overall, these experiments are interpreted as indicating that cognitive factors such as stimulus familiarity may override aspects of physical discriminability with many dimensions and stimuli, that, even though a cognitive dimension can be used to generate a logically proper set of stimuli, it does not necessarily act as other, more physical dimensions do, and that clarification of the functional role of a dimension is more important than attempts to locate stages.     

Does Religion Breed Trust? A Cross‐National Study of the Effects of Religious Involvement,Religious Faith,and Religious Context on Social Trust

Many previous studies have linked religiosity to social trust. Yet much of this relation remains insufficiently understood, which is partly due to the fact that religiosity is a multidimensional phenomenon. In this article, we identify several of those dimensions, including the integration in religious communities, the importance of God in people's lives, and the religious context. These dimensions give rise to different mechanisms that produce both trust‐enhancing and trust‐reducing effects. Data from the European Values Survey (2008) were used to test the resulting hypotheses, using multilevel logistic regression models. We conclude that the micro effects are ambivalent: integration in religious communities furthers trust, whereas religious socialization and the importance of God lower trust. On the macro level, we find a strong effect of Protestantism, which is in line with previous studies, but that remains puzzling since the individual‐level difference between Protestants and the other religious traditions was found to be very small. In addition, in contrast to other studies, we found that religious diversity increases social trust.     

The Contributions of Intrinsic and Extrinsic Reading Motivation to the Development of Reading Competence over Summer Vacation

This study addressed the role of reading motivation as a potential determinant of losses or gains in reading competence over six weeks of summer vacation (SV). Based on a sample of 223 third-grade elementary students, structural equation analyses showed that intrinsic reading motivation before SV contributed positively to both word and sentence comprehension after SV when controlling for comprehension performance before SV. These effects were mediated by reading amount. Extrinsic reading motivation did not show significant associations with end-of-summer comprehension scores. Taken together, the findings suggest that intrinsic reading motivation facilitates students’ development of reading comprehension over SV.     

Predicting career-entry pay expectations: The role of gender-based comparisons

This research investigated three sets of factors (career path factors, perceived job inputs, and reference group comparisons) as predictors of career-entry pay expectations for management students about to enter the workforce. As predicted, reference group comparisons accounted for a larger proportion of unique variance in students' pay expectations than either career path factors or perceived job inputs. In addition, same-sex comparisons were stronger predictors of career-entry pay expectations than opposite-sex comparisons. Practical implications and directions for future research are discussed.     

Imaginal elaboration of illustrations to facilitate fact learning: Creating memories of Prince Edward Island

Canadian students in grades 5 and 6 studied facts about the 10 Canadian provinces (e. g. Many very good plays are put on in Prince Edward Island). At study, each fact was accompanied by a picture of a stereotypical setting in the province (e. g. a picture of the lush farmland in Prince Edward Island). Half the subjects were instructed to learn by imagining the fact as stated occurring in the depiction (e. g. very good plays being produced in the lush farmland setting); half were told only to try hard to remember that the fact occurred in the particular province. The imagery instruction was effective, but only when children had previously mastered associations between the provinces and the pictures of the provinces. Naturalistically occurring pictures can be used by grade-school children to create elaborative images that facilitate acquisition of confusing facts, but only if children first know what the illustrations represent.     

Civil commitment laws in nineteenth-century New York

The roots of nineteenth-century American civil commitment law lay in English common law, in particular poor law, with its mixed motives of helping lunatics and of protecting the community from them. As state institutions assumed an increasingly large share of the burden of restraint in the 1840s and 1850s, such confinement decisions became subject to greater public scrutiny. This can be seen particularly clearly in New York State, which in 1842 passed a law requiring that two physicians examine each alleged lunatic and report their findings to a judge who then made the final commitment decision. After the Civil War, a number of legal decisions limited the state's power to initiate civil commitments to cases of clear social danger, though families were not so confined. An 1874 statute further tightened procedural guidelines for civil commitments. A State Commissioner in Lunacy was appointed to oversee the internal workings of lunatic asylums. Yet such legal “reforms” failed to slow the increasing tendency of both families and communities to use such institutions as long-term holding places for the socially marginal or threatening.
