Age trends in children's time-sharing performance

To investigate developmental differences in time-sharing performance, 60 boys, 20 in each of three age groups (7-, 10-, and 13-year-olds) performed an auditory matching task and a tracking task alone and concurrently, the latter under two sets of instructions. Decrements produced by concurrent performance were compared for the three age groups. When the time-shared tasks were presented as equally important, time-sharing produced significantly greater proportional decrements in the tracking performance of the younger children and for all age groups tracking task decrements were directly related to matching task difficulty. Subsequently, the children were instructed that one or the other of the tasks was more important and that they were to improve their performance on that task. All three age groups showed a significant improvement on the task emphasized by instructions. The relationship of the results to two models of information processing is discussed.     

On the possibility of the reemergence of a dysgenic trend with respect to intelligence in American fertility differentials

This paper examines the relationship between IQ and fertility in a sample of men and women aged 25–34 as of the late 1970s. This sample is of unusual interest for two reasons: (1) it is a national probability sample, representative of the non-institutional civilian population of the U.S. as a whole, and (2) it is for a post-World War II cohort. Most previous studies of the IQ/fertility relationship have employed nationally unrepresentative samples of cohorts born in the pre-war period, 1910–1940. The bias, in both time and place, of the samples used in these studies has not been adequately grasped by those who cite them as evidence of a eugenic trend with respect to intelligence.The major finding of these previous studies was that the IQ/fertility relationship is slightly positive, contrary to expectations though confirmatory of the so-called Eugenic Hypothesis. My working hypothesis is that this finding is special to the cohort chosen for study, i.e., one whose child-bearing took place during a period of rising birth rates (cohorts born between 1910 and 1940 were largely responsible for the baby boom after World War II). That is, in periods of rising birth rates, persons with higher intelligence tend to have fertility equal to, if not exceeding, that of the population as a whole. In periods of falling birth rates, the opposite is the case, according to my thesis.This thesis is generally supported by the data set described above. Fertility differentials to date within the post-World War II cohort, which entered its reproductive years during a period of falling birth rates, show a negative relationship between intelligence and fertility. The relationship is less negative for white men than for white women and for white women than for black women (black men are omitted from this study due to deficiencies in the data). The stated intentions of this cohort with respect to future fertility, if realized, will moderate the degree of this relationship, particularly for whites, but not change its sign.     

Sex differences in the structure of intelligence: A confirmatory factor analysis

The LISREL model of Jöreskog and Sörbom was used to perform a comparative factor analysis on intelligence data from four sex by generation groups. The covariance matrices for 10 psychometric ability measures were used to isolate Spatial and Verbal Intelligence factors. Results from a series of factor analysis models indicated substantial invariance in the factor pattern and factor covariance matrices, although the hypothesis of complete invariance in factor pattern was rejected. The groups did differ in observed and unique variances. The results were basically consistent with the hypothesis that males and females have similar intellectual structure, which would have been obscured had standardized factor analysis been employed. There were also sex and generation differences in the Spatial and Verbal factor means.     

The development of alertness

Two experiments explored variation in the alerting process across age and warning interval as well as the effects of alertness on subsequent processing. Experiment 1 obtained alertness functions for a group of 5-year-olds, 8-year-olds, and adults. Results revealed strong age differences in speed of alerting and in maintenance of alertness over a 1-sec interval. Five-year-olds alerted more slowly than older groups and sustained optimal alertness less well. Both groups of children showed more variability in alerting functions compared with adults. Experiment 2 examined the degree to which age differences in processing speed were attributable to differential speed and maintenance of alerting. Masking functions obtained across variations in the alerting interval revealed that when level of alertness was optimal in both 5-year-olds and adults, minimal age differences in processing speed were observed. During short, nonoptimal alerting intervals, speed of processing in adults was faster than in 5-year-old children. The pattern of results across studies suggested that alertness can fluctuate over time in young children, that level of alertness affects subsequent perceptual processing speed, and that developmental variation in speed and maintenance of alertness can partly explain observed age differences in processing speed. The potential role of alertness in more complex cognitive tasks is discussed.     

Need for achievement,career mobility,and the Mexican-American college graduate

Need for achievement and career mobility were measured for 111 Mexican-American college graduates. Those with a moderate need for achievement were found to have the highest upward mobility. Those with either a high or low need for achievement had lower mobility. The implications of this finding are discussed.     

Generalized multivariate lens model analysis for complex human inference tasks

A generalized multivariate lens model is presented which will permit the analysis of complex human inference tasks. Such tasks, occurring in their natural ecology, may involve judgments or decisions on multiple criteria and/ or where the influence of theoretically interesting partitions or augmentations of cue profiles needs to be systematically delineated. The generalized model incorporates the standard, hierarchical, and fully partialed lens models, the initial elaborations of which were made by N. J. Castellan (1972, Organizational Behavior and Human Performance, 8, 242–261) and T. R. Stewart (1976, Psychometrika, 41, 101–120). Both multivariate and univariate lens model equations are presented within a common notational system. An example which demonstrates some aspects of the generalized model is discussed in detail. Other potential applications for the model are outlined.     

Subjective utility,anticipated utility,and the Allais paradox

One of the most notable counterexamples to expected utility theory is the “Allais paradox” (M. Allais, 1953, Econometrica, 31, 503–546). A number of alternative theories have been proposed in an attempt to resolve this paradox, notably including Karmarkar, 1978, Karmarkar, 1979, 24, 67–72). It is shown that SWU theory necessarily involves violations of dominance, but that the theory can be modified to avoid these violations. The result is a special case of J. Quiggin's anticipated utility theory (1982, Journal of Economic Behaviour and Organisation, 3, 323–343).     

Validation de la version française d’une échelle abrégée de coping religieux : Brief-RCOPE

The involvement of religious beliefs and practices in the way of coping with stressful events is coined by the term of religious coping. It is commonly distinguished the positive from the negative patterns of religious coping (i.e., a secure and a less secure relationship with God respectively) as assessed by the Brief RCOPE. The interest for the religious coping patterns lies in their predictive value for the quality of the adjustment to stress. After controlling for the effects of sociodemographic variables, and nonreligious coping measures, the positive pattern is a significant predictor of well-being while the negative pattern promotes a poorer physical and mental health. This study was designed to validate the French version of the Brief RCOPE.

‘Interfaith dialogue’ as a form of opposition of ‘minority religions’ to governmental pressure in Russia

Russian governmental policy toward non-traditional religious groups, especially so-called New Religious Movements (NRMs), is discriminatory. Despite Russia’s formal secularity, the government strongly supports the Russian Orthodox Church (ROC), a position which results in various limitations on many other religious groups. As a result, legal actions have been initiated against new religious groups, for example the Bhagavad Gita trial in Tomsk, Siberia, and the designation of the literature of the Jehovah’s Witnesses as ‘extremist’. However, pressure by the government can sometimes lead to the development of spontaneous interreligious oppositional associations. One important example is the ‘interfaith dialogue’ in Tomsk, where local leaders or representatives of religious groups, such as the Episcopal, Jewish, and Latter-day Saints (Mormon) churches as well as the Hare Krishna movement, unorthodox Buddhist groups, and local pagan movements, united to oppose governmental and ROC efforts to disband a Hare Krishna group in the Tomsk area. This research note presents results of a case study, which involved participant observation, of the phenomenon of oppositional interfaith dialogue in Tomsk in the period 2011–2014. I discuss factors that influenced its appearance, its relationship with the local government, and the methods of cooperation between the different religious groups within this association and offer some theoretical interpretations of these developments. The results of this case study illustrate new and important modern relationships between minority religions and the government in Russia.     

Paradigm shift in religious education: a reply to Jackson,or why religious education goes to war

This article provides a defence of my theoretical analysis of paradigm shift in contemporary religious education, particularly in light of Robert Jackson’s (2015) article published in this journal: ‘Misrepresenting religious education’s past and present in looking forward: Gearon using Kuhn’s concepts of paradigm, paradigm shift and incommensurability’. The core of Jackson’s concerns is my adaptation of Kuhn’s concepts of paradigm, paradigm shift and incommensurability to religious education. Defending in turn my use of these concepts – of paradigm, paradigm shift and incommensurability – I conclude that Jackson’s critique is in and of itself an apt demonstration of the position he seeks to attack. Drawing wider parallels with the methodological ‘paradigm wars’ in the social sciences I argue that the paradigms are why religious education too goes to ‘war’.
