Cognitive development in 7- to 24-month-old extremely/very-to-moderately/late preterm and full-term born infants: The mediating role of focused attention

The present study analyzed the links between prematurity, attention, and global cognitive performance in infancy and early childhood. At 7 months, focused attention (FA) was examined with an object examination task in 93 preterm infants (39 of them born extremely/very preterm, 54 born moderately/late preterm, and 38 infants born full-term). Global cognition was assessed at 7 and 24 months with the Bayley-II cognitive scale. Groups did not differ with respect to global cognitive performance but FA of infants born extremely/very preterm was significantly lower than in infants born moderately/late preterm. FA correlated significantly with both prematurity and cognitive performance at 7 months of age but not with global cognition in childhood. Findings point to a subtle adverse effect of prematurity on early attention and reveal evidence for the mediating role of FA on the effect of prematurity on cognition.     

On the development of perfectionism in adolescence: Perceived parental expectations predict longitudinal increases in socially prescribed perfectionism

Adolescence is regarded a key period when individual differences in perfectionism develop. Yet, so far only a few longitudinal studies have investigated the development of perfectionism in adolescents. Using a longitudinal correlational design with 381 adolescents aged 15–19 years, the present study investigated whether perceived parental expectations and criticism predicted longitudinal increases in self-oriented and socially prescribed perfectionism over 7–9 months. Results showed that perceived parental expectations predicted longitudinal increases in socially prescribed perfectionism: Adolescents who perceived that their parents had high expectations of them at Time 1, showed increased socially prescribed perfectionism from Time 1 to Time 2 compared to adolescents who did not perceive their parents having such high expectations. No such effect was found for self-oriented perfectionism. The findings provide supportive evidence for the social expectations model of the development of perfectionism regarding socially prescribed perfectionism, but not self-oriented perfectionism. Implications of this finding for the understanding of the development of perfectionism and future studies are discussed.     

Dynamic systems as tools for analysing human judgement

With the advent of computers in the experimental labs, dynamic systems have become a new tool for research on problem solving and decision making. A short review of this research is given and the main features of these systems (connectivity and dynamics) are illustrated. To allow systematic approaches to the influential variables in this area, two formal frameworks (linear structural equations and finite state automata) are presented. Besides the formal background, the article sets out how the task demands of system identification and system control can be realised in these environments, and how psychometrically acceptable dependent variables can be derived.     

Twilight of a Dilemma: A Réplique

In light of the nine open peer commentaries, we further explicate the social projection model and highlight its boundaries. We acknowledge that our model—like any extant model—cannot account for all the available empirical data. Yet the model is strong because it explains cooperation in a variety of social dilemmas and experimental games while deploying only one psychological construct as a parameter. Compared with its competitors, the social projection model more openly recognizes the struggle with uncertainty a person caught in a social dilemma must confront. In a series of simulations (and brute math), we show that cooperation can survive when players (humans) stay the Bayesian course.     

Are boycott motives rationalizations?

Previous models of boycott motivation are incomplete because they only consider beliefs and attitudes. This article argues that consumers' proximity to the consequences of the critical actions of a company is the primary trigger of the desire to boycott. As consumers need to justify this desire, they search for supportive arguments. Thus, the arguments consumers give to explain why they are boycotting or not are pre‐decisional rationalizations rather than independent rational considerations. Consequently, the paper suggests that scholars need to respecify the antecedents identified in prior studies. These constructs are mediator variables of the indirect influence of proximity on boycott participation. The paper tests the assumptions on the basis of survey data gathered from 544 consumers using the example of a real boycott that was called in response to factory relocation. The model proposed was tested by means of partial least squares regression analysis. The mediation hypotheses were examined using simple and multiple mediation tests. The empirical study confirms that boycott motives are mainly rationalizations of a pre‐existing desire to boycott, which is contingent on proximity. Managerial implications and avenues for further research are proposed. Copyright © 2013 John Wiley & Sons, Ltd.     

Subjective Difficulty of Movements With Ongoing Visual Control

Objective difficulty of a single-component visually controlled movement may be defined by Fitts's (1954) Index of Difficulty, which is a measure of difficulty in the sense that movement time is linearly related to the objective measure. For movements that have multiple components, it becomes difficult to determine an objective measure of task difficulty due to unknown interactions between components of the movement and interactions with other factors. Thus, it may be necessary to use indirect methods for allocating a measure of task difficulty. The purpose of the study was to determine whether participants could validly construct a subjective measure of the movement difficulty and whether this measure was related to the known objective measure of difficulty. Experiments showed that for single-component movements, there was a close relationship between measures of subjective and objective difficulty. With two-component visually controlled movements it was found that subjective difficulty could be related to objective difficulty, but not as simply as for single-component tasks.     

The Assessment of Self-Oriented and Socially Prescribed Perfectionism: Subscales Make a Difference

Campbell and Di Paula (2002) Campbell, J. D. and Di Paula, A. 2002. “Perfectionistic self-beliefs: Their relation to personality and goal pursuit”. In Perfectionism, Edited by: Flett, G. L. and Hewitt, P. L. 181–198. Washington, DC: American Psychological Association.  [Google Scholar] suggested differentiating Perfectionistic Striving and Importance of Being Perfect subscales when measuring self-oriented perfectionism and Others’ High Standards and Conditional Acceptance subscales when measuring socially prescribed perfectionism. In this study, we investigated the utility of this differentiation by analyzing data from 1,041 students and examining correlations with positive striving and maladaptive evaluation concerns aspects of perfectionism and with positive and negative indicators of well-being and psychological adjustment. As expected, (a) Perfectionistic Striving scores showed higher correlations with positive striving aspects of perfectionism and with positive indicators of well-being and adjustment than Importance of Being Perfect scores, and (b) Conditional Acceptance scores showed higher correlations with maladaptive evaluation concerns aspects of perfectionism and with negative indicators of well-being and adjustment than Others’ High Standards scores. The findings indicate that Campbell and Di Paula's differentiation provides for a more detailed and informative assessment of multidimensional perfectionism and its different aspects. Moreover, it provides for new insights into self-oriented and socially prescribed perfectionism and their relationships and associations.     

Honderich,Davidson, and the question of mental holism

Honderich's defence of aspects of his correlationist theory against many objections actually or likely to be raised today, in particular from the point of view of Davidson's anomalous monism and psychological holism, is accepted as largely successful. But it is suggested that, even if Davidson's theory is wrong‐headed, another kind of holism, more deeply ontological and less linguistic, regarding the mental seems to be true, and presents difficulties for Honderich's correlationism. Finally, it is contended that a panpsychist kind of identity theory escapes his strictures on identity theories and is probably true; however, the identity is, in virtue of certain synthetic necessities about the course of a stream of consciousness, either only between particular mental and physical events (and thus anomalously monist in Davidson's sense), or if it holds also between types of mental and of brain event then certain quite striking consequences follow as to the character of the fullest possible explanation of what goes on in the brain.
