When vaccinating against information reduction works and when it does not work

Practice not only affects how information is processed, but also which information is processed. The Information-Reduction Hypothesis (i.e. Haider & Frensch, 1996) holds that — with practice — irrelevant task information (i.e. information that is not logically needed to correctly perform the task) is discarded from processing. Recently, Gaschler and Frensch (2007) have demonstrated that Information Reduction is not affected by the frequency with which individual task configurations are presented: well-practiced and little-practiced irrelevant task configurations are discarded at the same point in time during practice; Information Reduction is thus an item-general phenomenon. These findings suggest that Information Reduction is at least in part a consequence of top-down, voluntary control. In the present research, we ask how tasks can be constructed such that Information Reduction is avoided. Our results show that item-general Information Reduction is observed even when it leads to severe processing costs (i.e. errors). On the whole, the present results are in line with models of skill acquisition incorporating top-down modulation (e.g. Haider & Frensch, 2002) and are incompatible with purely data-driven accounts of skill acquisition (e.g. Logan, 1988; Nosofski & Palmeri, 1997; Palmeri, 1997; Rickard, 2004).     

Cognitive and Interpersonal Predictors of Stress Generation in Children of Affectively Ill Parents

Stress generation is a process in which individuals, through their depressive symptoms, personal characteristics, and/or behaviors, contribute to the occurrence of stressful life events. While this process has been well documented in adults, few studies have examined it in children. The present study examines whether cognitive and interpersonal vulnerability factors to depression contribute to stress generation in children, independent of their current depressive symptoms. Participants included 140 children (ages 6 to 14) and one of their parents. During an initial assessment, children completed self-report measures assessing cognitive and interpersonal vulnerability factors to depression. Children and their parents also completed measures assessing depressive symptoms. One year later, children and their parents participated in a semi-structured interview assessing the occurrence of stressful life events in the past year. Multi-level modeling results provided strong support for the stress generation process in children of affectively ill parents and highlight the importance of considering gender and age moderation effects.

Intelligence and persisting with medication for two years: Analysis in a randomised controlled trial

The study examined whether verbal intelligence is associated with persisting to take medication for up to two years. The design is a prospective follow-up of compliance with taking medication in high-risk individuals participating in a randomised, placebo-controlled trial set in Central Scotland. Participants were 1993 people aged between 50 and 77 years with an ankle brachial index ≤ 0.95. The medication was 100 mg aspirin or placebo daily.The principal outcome measure was continuing with taking medication or stopping it due to having ‘changed one's mind’. Higher verbal intelligence was associated with a greater likelihood of continuing to take medication up to two years after randomisation. For a standard deviation increase in Mill Hill Vocabulary Scale score, risk of stopping medication in the first two years of the study was 0.75 (95% CI 0.64 to 0.87, p < 0.001). Comparing the highest and lowest quartiles of IQ, the lowest IQ group's relative rate of stopping medication was 2.51 (95% CI 1.52 to 4.22). The effect was not attenuated after adjustment for sex, smoking, or level of deprivation. Verbal intelligence is associated with continuing, medium-to-long term engagement with health self-care, even in the face of uncertainty about whether active treatment is being received, whether the treatment is known to be effective in general, and whether it will be helpful to the individual taking it. Such persisting with potentially helpful health behaviours in the face of uncertainty might partly explain why people with higher intelligence live longer and suffer less morbidity from chronic diseases.     

Intentionality,Cognitive Integration and the Continuity Thesis

Naturalistic philosophers ought to think that the mind is continuous with the rest of the world and should not, therefore, be surprised by the findings of the extended mind, cognitive integration and enactivism. Not everyone is convinced that all mental phenomena are continuous with the rest of the world. For example, intentionality is often formulated in a way that makes the mind discontinuous with the rest of the world. This is a consequence of Brentano’s formulation of intentionality, I suggest, and can be overcome by revealing that the concept of intentional directedness as he receives it from the Scholastics is quite consistent with the continuity thesis. It is only when intentional directedness is conjoined with intentional inexistence that intentionality and content are consistent with a discontinuity thesis (such as Brentano’s thesis). This makes room to develop an account of intentional directedness that is consistent with the continuity thesis in the form of Peirce’s representational principle. I also argue against a form of the discontinuity thesis in the guise of the derived/underived content distinction. Having shown that intentionality is consistent with the continuity thesis I argue that we should focus on intentionality and representation as bodily enacted. I conclude that we would be better off focussing on representation and intentionality in action rather than giving abstract functional accounts of extended cognition.

A method for eliciting scale errors in preschool classrooms

Six preschool classrooms, containing children between the ages of 4.0 and 40.0 months, were seeded with miniature items to examine how easily scale errors could be elicited. Observations occurred over a period of 3 months, with a total of 280 min of observations per classroom. A concealed observer documented all interactions with the miniature items. A total of 93 scale errors occurred, with a higher frequency committed by the younger children. These results confirm findings from previous research and suggest that scale errors can be effectively elicited in a preschool classroom. Our approach may provide a useful method for systematically studying the factors that influence scale errors.     

The Big-5 ± 2? The impact of cognitive complexity on the factor structure of the five-factor model

Despite the popularity and prevalence of the five-factor model (FFM) of personality, numerous questions regarding its psychometric properties have yet to be investigated. One issue of particular concern is the underlying premise that these five personality factors are universally shared by all individuals. The present study examined the impact of cognitive complexity on the FFM by directly assessing whether individuals with higher or lower levels of cognitive complexity have personalities comprised of a greater or lesser number of factors, respectively, than the five widely accepted factors outlined by the FFM. Results indicated that individuals with lower levels of cognitive complexity have personalities best described by a three-factor model, whereas individuals with higher levels of cognitive complexity have personalities best described by a seven-factor model. In light of these findings, the appropriateness of universally applying the FFM to individuals of differing levels of cognitive complexity is discussed.     

Brain mechanisms associated with background monitoring of the environment for potentially significant sensory events

Background monitoring is a necessary prerequisite to detect unexpected changes in the environment, while being involved in a primary task. Here, we used fMRI to investigate the neural mechanisms that underlie adaptive goal-directed behavior in a cued task switching paradigm during real response conflict or, more generally, when expectations on the repetitive features of the environment were violated. Unexpected changes in sensory stimulus attributes in the currently unattended stimulus dimension thereby led to activations in a bilateral network comprising inferior lateral frontal, intraparietal, and posterior medial frontal brain regions, independent of whether these attributes elicited a factual response conflict or not. This fronto-parietal network may thus play an important role in adaptive responding to potentially significant events outside the current focus of attention.     

Benefits of physical exercise on executive functions in older people with Parkinson’s disease

The benefits of physical exercise on cognitive functioning have been reported in the literature, but the potential benefits to slow the eventual decline in executive functioning (EF) caused by neurodegeneration from Parkinson’s Disease (PD) have rarely been studied. Thus the objective of this study was to analyze the effects of a multimodal physical exercise program on EF in older people with Parkinson’s disease. The EF of the older people was evaluated by neuropsychological testing, and for confounding variables such as attention, depressive symptoms and anxiety, before and after intervention. The 20 participants were assigned into Control (CG) and Trained (TG) Groups. The TG participated in generalized physical training for 6 months. The ANOVA showed a significant interaction (p < .05) that indicated a beneficial contribution of training on EF. No significant interactions were found in the results for confounding variables between groups and pre- and post-intervention, which supports the beneficial findings of physical exercise training on EF.     

The dynamic infrastructure of mind—A hypothesis and some of its applications

A mechanism underlying the computational properties of the cognitive architecture is construed based on a minimal list of operational clusters. This general processing mechanism constitutes the dynamic infrastructure of mind (DIM). DIM consists in categories of mental operations foundational for learning that contain inborn components called inner operations, which are self-developing in the interaction mind-environment. Within the DIM paradigm, the input cognitive systems are not domain specific or core-knowledge specific, they are operational specific and capable of further developments that become domain specific while experiencing the environment. Arguments for this construal come from three sources: literature review, data collected through classroom observations, and a four-year experimental study of teaching and learning mathematics in primary grades. The outcomes of that experiment led to a methodology of learning based on activating the operational infrastructure of mind, which enhances students' flexibility of thinking and predicts the capacity to solve creatively a variety of problems.     

When learning is not enough: A process model of expatriate adjustment as cultural cognitive dissonance reduction

Although considerable organizational research exists on the topic of expatriate adjustment and early departure, little has focused on the actual psychological processes causing change in adjustment outcomes. Specifically, researchers have not focused on cognitive dissonance that arises from adopting or condoning culturally expected behaviors that are inconsistent with the expatriate’s own values or attitudes. We propose that dissonance experiences and the methods used for dissonance reduction influence expatriates’ adjustment outcomes and, in turn, their tendency for early departure. We further specify key situational and individual difference constructs that regulate these causal relationships. Along with a greater understanding of cross-cultural adjustment, the current model suggests new directions for expatriate research and management.
