The Relations Between Patterning,Executive Function,and Mathematics

Patterning, or the ability to understand patterns, is a skill commonly taught to young children as part of school mathematics curricula. It seems likely that some aspects of executive function, such as cognitive flexibility, inhibition, and working memory, may be expressed in the patterning abilities of children. The primary objective of the present study was to examine the relationship between patterning and executive functioning for first grade children. In addition, the relations between patterning, executive functioning, mathematics, and reading were examined. The results showed that patterning was significantly related to cognitive flexibility and working memory, but not to inhibition. Patterning, cognitive flexibility, and working memory were significantly related to mathematical skills. Only patterning and working memory were significantly related to reading. Regression analyses and structural equation modeling both showed that patterning had effects on both reading and mathematics measures, and that the effects of cognitive flexibility were entirely mediated by patterning. Working memory had independent effects on reading and mathematics, and also effects moderated by patterning. In sum, these findings suggest that cognitive flexibility and working memory are related to patterning and express their effects on reading and mathematics in whole or in part through patterning.     

Die Zweite Moderne und die Angewandte Kriminologie

This article analyses the recent changes in modern society (??second modernity??) and their importance for criminological questions. These changes increase the risk of biographical crises of individuals which can result in the committing of crimes. Therefore, a review of the diagnostic and prognostic system of ??applied criminology?? was necessary. As a result the ??applied criminology?? had to be adapted and a new biographical type of ??crime in crises?? was deduced from this review. The value orientation and individual relevant aspects, for example special places, persons or strong interests, play a key role in appraising the new biographical type of ??crime in crises??. This new type fits to the developments of the second modernity and completes the system of ??applied criminology??.     

A General Structure of Job Performance: Evidence from Two Studies

Purpose  

The purpose of this study is to test alternative models of job performance based on competing categorization criteria.     

Driving impairs talking

It is well known that conversation (e.g, on a cell phone) impairs driving. We demonstrate that the reverse is also true: Language production and comprehension, and the encoding of the products of comprehension into memory, are less accurate when one is driving. Ninety-six pairs of drivers and conversation partners engaged in a story-retelling task in a driving simulator. Half of the pairs were older adults. Each pair completed one dual-task block (driving during the retelling task) and two single-task control blocks. The results showed a decline in the accuracy of the drivers’ storytelling and of their memory for stories that were told to them by their nondriving partners. Speech production suffered an additional cost when the difficulty of driving increased. Measures of driving performance suggested that the drivers gave priority to the driving task when they were conversing. As a result, their linguistic performance suffered.     

Intonational marking of given and new information: Some consequences for comprehension

The role of intonation in conveying discourse relationships in auditory sentence comprehension was investigated in two experiments. Using the simple comprehension time paradigm, Experiment 1 found that sentences with accented new information were understood faster than sentences with a neutral intonation contour and that the presence of accent in context sentences facilitated comprehension of subsequent targets. Both experiments showed faster comprehension times in conditions in which accent placement was appropriate for the information structure of the sentence. In Experiment I, comprehension times were faster when the accent fell on the information focus than when it fell elsewhere in the sentence. In Experiment 2, faster times resulted when new information was accented and given information was not, compared to conditions in which this accent pattern was reversed. This effect held for both active and passive sentences, and whether the new information occurred in the subject or object position.     

Trend in correlated proportions

A random effects probit model is developed for the case in which the same units are sampled repeatedly at each level of an independent variable. Because the observed proportions may be correlated under these conditions, estimating their trend with respect to the independent variable is no longer a standard problem for probit, logit or loglinear analysis. Using a qualitative analogue of a random regressions model, we employ instead marginal maximum likelihood to estimate the average latent trend line. Likelihood ratio tests of the hypothesis of no trend in the average line, and the hypothesis of no differences in average trend lines between experimental treatments, are proposed. We illustrate the model both with simulated data and with observed data from a clinical experiment in which psychiatric patients on two drug therapies are rated on five occasions for the presence or absence of symptoms.Supported by a grant from the MacArthur Foundation and National Science Foundation Grant BNS85-11774.The authors are indebted to James Heckman for calling our attention to the Clark algorithm.     

Closed-class immanence in sentence production

The closed-class hypothesis asserts that function words play a privileged role in syntactic processes. In language production, the claim is that such words are intrinsic to, identified with, or immanent in phrasal skeletons. Two experiments tested this hypothesis with a syntactic priming procedure. In both, subjects tended to produce utterances in the same syntactic forms as priming sentences, with the structures of the self-generated sentences varying as a function of differences in the structures of the primes. Changes in the closed-class elements of the priming sentences had no effect on this tendency over and above the impact of the structural changes. These results suggest that free-standing closed-class morphemes are not inherent components of the structural frames of English sentences.
