Traditional Christian Belief and Belief in the Supernatural: Diverging Trends in the Netherlands Between 1979 and 2005?

Is there an ongoing decline in religious beliefs in the Netherlands? Using cross-sectional data from 1979 up to 2005, we focus on traditional Christian faith and belief in the supernatural; the literature suggests that they undergo diverging trends. We first describe these trends using the Social and Cultural Developments in the Netherlands surveys covering the 1979–2005 period. Explanations for the trends are formulated and tested using OLS regression models and a counterfactional simulation technique. Our findings indicate that during the 1979–2005 period both traditional Christian faith and belief in the supernatural declined, although the latter at a slower rate. Since church membership rates are continuously declining as well, belonging and believing still go hand in hand in the Netherlands. The most important explanation for both the decline in traditional Christian faith and the decline in belief in the supernatural is the slow but continuous replacement of older religious affiliated cohorts with younger nonaffiliated cohorts.     

Foveal-to-peripheral priming in letter identification reflects response bias, not enhanced visibility

Several studies have suggested that it might be easier to identify a letter when its replication is simultaneously presented in the visual display. We have measured identification accuracy for a memorized target letter that was shown in the peripheral field in two conditions in which a letter either identical or different in shape was flashed simultaneously at fixation. The results of three forced-choice experiments showed that, contrary to Geiger and Lettvin's (1986) previous findings, an identity prime did not improve the visibility of a temporally backward masked target letter. However, the foveal prime letter could apparently bias the subject's decision so that he/she was much more ready to report the more visible prime letter as the peripheral target.     

Image reconstruction and Gestalt formation in human spatial vision

A sampling theoretical and experimental framework for the study of spatial vision is introduced. It is suggested that spatial Gestalt perception can be fruitfully analyzed by applying the concepts and methods of modern spatial filtering theory as they are known in the theory of image sampling and reconstruction. Demonstrations of the sampling processes in spatial vision are given and an experimental method for estimating the spatial reconstruction power of the human visual system is described. The experimental results presented suggest that high spatial frequency information has a special significance for human vision. Evidently, high frequency information is transmitted more easily through the visual system than has been generally assumed on the basis of contrast sensitivity studies.     

Internal control and success orientation in a token economy for emotionally disturbed adolescents.

Forty-one emotionally disturbed adolescents were tested at each of three token economy levels on Rotter's Internal-External Locus of Control Scale and Guevar's Success-Failure Inventory. Delay of reinforcement (immediate, daily, weekly) was the primary differentiation between levels. One-way analyses of variance indicated a change across levels in the direction of more perceived internal control of behavior (p less than .025) and a greater success orientation (p less than .005). Change scores were not correlated with length of time in the program. Results suggest that the token economy as an external source of control is not necessarily incompatible with increasing patient expectancies of present and future control of the environment.     

The Relationship Between Diverse Components of Intelligence and Creativity

Intelligence and creativity are accounted for in terms of two different mental operations referred to as ‘convergent thinking’ and ‘divergent thinking’, respectively. Nevertheless, psychometric evidence on the relationship between intelligence and creativity has been controversial. To clarify their relationship, we characterized the relationship between diverse components of intelligence and creativity through the administration of psychometric tests on a large sample (WAIS, RPM, and TTCT‐figural: n = 215; TTCT‐verbal: n = 137). The general intelligence factor (g) score showed significant correlations with both TTCT‐figural and TTCT‐verbal scores. However, sub‐dimensional analysis demonstrated that their association was attributable to the specific components of both TTCTs (TTCT‐figural: Abstractness of Titles, Elaboration, and Resistance to Premature Closure; TTCT‐verbal: Flexibility) rather than to their common components (Fluency and Originality). Among the intelligence sub‐dimensions, crystallized intelligence (gC) played a pivotal role in the association between g and the specific components of both TTCTs. When the total sample was divided into two IQ groups, these phenomena were more evident in the average IQ group than in the high IQ group. These results suggest that the mental operation of creativity may be different from that of intelligence, but gC may be used as a resource for the mental operation of creativity.
