Executive functions in decision making: An individual differences approach

This individual differences study examined the relationships between three executive functions (updating, shifting, and inhibition), measured as latent variables, and performance on two cognitively demanding subtests of the Adult Decision Making Competence battery: Applying Decision Rules and Consistency in Risk Perception. Structural equation modelling showed that executive functions contribute differentially to performance in these two tasks, with Applying Decision Rules being mainly related to inhibition and Consistency in Risk Perception mainly associated to shifting. The results suggest that the successful application of decision rules requires the capacity to selectively focus attention and inhibit irrelevant (or no more relevant) stimuli. They also suggest that consistency in risk perception depends on the ability to shift between judgement contexts.     

Examining the Growth Trajectories of Physical Education Students’ Motivation,Enjoyment, and Physical Activity: A Person-Oriented Approach

The study examined the growth trajectories in 757 (M age = 12.71) Finnish middle school students’ intrinsic and extrinsic motivation along with their enjoyment and physical activity. In addition, the study aimed to examine the role of intrinsic and extrinsic physical education motivation in the development in adolescents’ enjoyment and physical activity by identifying adolescents’ subgroups. Adolescents’ enjoyment and physical activity declined, intrinsic motivation was stable, and extrinsic motivation increased across middle school. Adolescents with highest levels of intrinsic motivation and moderate to high levels of extrinsic regulation had the highest levels of enjoyment and physical activity.     

Predictors of Self-Reported Prospective and Retrospective Memory in a Population-Based Sample of Older Adults

In this article, the authors examined predictors of self-reported everyday memory failures using the Prospective and Retrospective Questionnaire (PRMQ; Smith, Della Sala, Logie, &; Maylor, 2000 Smith, G. V., Della Sala, S., Logie, R. H. and Maylor, E. A. M. 2000. Prospective and retrospective memory in normal ageing and dementia: A questionnaire study. Memory, 8: 311–321. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) in a population-based sample of older adults (age range = 60–90 years; N = 250). The results showed that a higher frequency of reported failures was associated with lower scores on the personality dimension of self-directedness as assessed by the Temperament and Character Inventory (TCI; Cloninger, Dragan, Svrakic, &; Przybeck, 1993 Cloninger, R. C., Dragan, M. S., Svrakic, D. M. and Przybeck, T. R. 1993. A psychobiological model of temperament and character. Archives of General Psychiatry, 50: 975–990. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) and more depressive symptoms on the Center for Epidemiological Studies Depression Scale (CES-D; Radloff, 1977 Radloff, L. S. 1977. The CES-D scale: A self-report depression scale for research in the general population. Applied Psychological Measurement, 1: 385–401. [Crossref], [Web of Science ®] , [Google Scholar]). However, PRMQ scores showed no relationships with objective memory ability, as reflected by a series of retrospective memory measures and a measure of prospective memory. Neither were the PRMQ scales associated with general cognitive functioning as assessed by the Mini-Mental State Examination (MMSE; Folstein, Folstein, &; McHugh, 1977). Taken together, the results indicate that within the older population, self-reported memory as assessed by the PRMQ may reflect mood-state and personality factors rather than individual differences in memory and cognitive ability.     

Wittgenstein and the Criticism of Religion A Case Study

This article discusses the relevance of Wittgenstein's remarks on the doctrine of predestination for an understanding of his approach to religious matters. On the one hand, Wittgenstein held that this doctrine involves distorted concepts and is ethically and religiously nonsensical. On the other, he stated that others may find it “good and godly.” He seems to suggest that personal experience shapes the genuine meaning of the doctrine of predestination. The points that emerge cast light on tensions prevailing between Wittgenstein's conception of meaning as essentially a social and inter-subjective matter and his individualist perspective in the matter of religion. These issues lie at the heart of the dispute over Wittgenstein's views on the possibility of a philosophical criticism of religion.     

What is Reification? A Critique of Axel Honneth

In this paper I criticise Axel Honneth's reactualization of reification as a concept in critical theory in his 2005 Tanner Lectures and argue that he ultimately fails on his own terms. His account is based on two premises: (1) reification is to be taken literally rather than metaphorically, and (2) it is not conceived of as a moral injury but as a social pathology. Honneth concludes that reification is “forgetfulness of recognition”, more specifically, of antecedent recognition, an emphatic and engaged relationship with oneself, others and the world, which precedes any more concrete relationship both genetically and categorially. I argue against this conception of reification on two grounds. (1) The two premises of Honneth's account cannot be squared with one another. It is not possible to literally take a person as a thing without this being a recognisable moral injury, and, therefore, I suggest that there are no cases of literal reification. (2) Honneth's account is essentially ahistorical, because it is based on an anthropological model of recognition that tacitly equates reification with autism. In conclusion, I suggest that any successful account of reification must (i) take reification metaphorically and (ii) offer a social-historical account of the origin(s) of reification.     

Dietary Control of Rumination: Two Case Studies

Chronic rumination of 2 institutionalized men with profound mental retardation was treated using a dietary approach. In the first case, a peanut butter or honey supplement was given, whereby 2 spoonfuls of either food was added to every meal, with drinks moved to a later time. In the second case, food satiation together with a honey supplement was applied. In the first case, an ABABACA design was used. In the second case, the non-experimental AB design was applied. In both cases, rapid decrease in rumination was achieved. Anecdotal follow-up confirmed the permanency of the results.     

Object detection in natural scenes: Independent effects of spatial and category-based attention

Humans are remarkably efficient in detecting highly familiar object categories in natural scenes, with evidence suggesting that such object detection can be performed in the (near) absence of attention. Here we systematically explored the influences of both spatial attention and category-based attention on the accuracy of object detection in natural scenes. Manipulating both types of attention additionally allowed for addressing how these factors interact: whether the requirement for spatial attention depends on the extent to which observers are prepared to detect a specific object category—that is, on category-based attention. The results showed that the detection of targets from one category (animals or vehicles) was better than the detection of targets from two categories (animals and vehicles), demonstrating the beneficial effect of category-based attention. This effect did not depend on the semantic congruency of the target object and the background scene, indicating that observers attended to visual features diagnostic of the foreground target objects from the cued category. Importantly, in three experiments the detection of objects in scenes presented in the periphery was significantly impaired when observers simultaneously performed an attentionally demanding task at fixation, showing that spatial attention affects natural scene perception. In all experiments, the effects of category-based attention and spatial attention on object detection performance were additive rather than interactive. Finally, neither spatial nor category-based attention influenced metacognitive ability for object detection performance. These findings demonstrate that efficient object detection in natural scenes is independently facilitated by spatial and category-based attention.     

Cognitive burden of survey questions and response times: A psycholinguistic experiment

An important objective in survey question design is to write clear questions that respondents find easy to understand and to answer. This contribution identifies the factors that influence question clarity. Theoretical and empirical evidence from psycholinguistics suggests that specific text features (e.g., low‐frequency words (LFRWs), left‐embedded syntax) cause comprehension difficulties and impose a high cognitive burden on respondents. To examine the effect of seven different text features on question clarity, an online experiment was conducted in which well‐formulated questions were compared to suboptimal counterparts. The cognitive burden of the questions was assessed with response times. Data quality was compared in terms of drop‐out rates and survey satisficing behaviour. The results show that at least six of the text features are relevant for the clarity of a question. We provide a detailed explanation of these text features and advise survey designers to avoid them when crafting questions. Copyright © 2009 John Wiley & Sons, Ltd.     

The effect of multiple indicators on the power to detect inter‐individual differences in change

Hertzog et al. evaluated the statistical power of linear latent growth curve models (LGCMs) to detect individual differences in change, i.e., variances of latent slopes, as a function of sample size, number of longitudinal measurement occasions, and growth curve reliability. We extend this work by investigating the effect of the number of indicators per measurement occasion on power. We analytically demonstrate that the positive effect of multiple indicators on statistical power is inversely related to the relative magnitude of occasion‐specific latent residual variance and is independent of the specific model that constitutes the observed variables, in particular of other parameters in the LGCM. When designing a study, researchers have to consider trade‐offs of costs and benefits of different design features. We demonstrate how knowledge about power equivalent transformations between indicator measurement designs allows researchers to identify the most cost‐efficient research design for detecting parameters of interest. Finally, we integrate different formal results to exhibit the trade‐off between the number of measurement occasions and number of indicators per occasion for constant power in LGCMs.
