The Effect of Parents’ Literacy Skills and Children’s Preliteracy Skills on the Risk of Dyslexia

The combination of investigating child and family characteristics sheds light on the constellation of risk factors that can ultimately lead to dyslexia. This family-risk study examines plausible preschool risk factors and their specificity. Participants (N?=?196, 42 % girls) included familial risk (FR) children with and without dyslexia in Grade 3 and controls. First, we found impairments in phonological awareness, rapid naming, and letter knowledge in FR kindergartners with later dyslexia, and mild phonological-awareness deficits in FR kindergartners without subsequent dyslexia. These skills were better predictors of reading than arithmetic, except for rapid naming. Second, the literacy environment at home was comparable among groups. Third, having a dyslexic parent and literacy abilities of the non-dyslexic parent related to offspring risk of dyslexia. Parental literacy abilities might be viewed as indicators of offspring’s liability for literacy difficulties, since parents provide offspring with genetic and environmental endowment. We propose an intergenerational multiple deficit model in which both parents confer cognitive risks.     

Health inequality and careers

Structural explanations of career choice and development are well established. Socioeconomic inequality represents a powerful factor shaping career trajectories and economic outcomes achieved by individuals. However, a robust and growing body of evidence demonstrates a strong link between socioeconomic inequality and health outcomes. Work is a key factor explaining differences in income and lifestyle. It seems unavoidable that inequality in careers has profound consequences for health and well-being, but this relationship is largely ignored by career scholars. Some implications of health inequality for career guidance interventions are suggested.     

Neuroscience,quantum indeterminism and the Cartesian soul

Quantum indeterminism is frequently invoked as a solution to the problem of how a disembodied soul might interact with the brain (as Descartes proposed), and is sometimes invoked in theories of libertarian free will even when they do not involve dualistic assumptions. Taking as example the Eccles–Beck model of interaction between self (or soul) and brain at the level of synaptic exocytosis, I here evaluate the plausibility of these approaches. I conclude that Heisenbergian uncertainty is too small to affect synaptic function, and that amplification by chaos or by other means does not provide a solution to this problem. Furthermore, even if Heisenbergian effects did modify brain functioning, the changes would be swamped by those due to thermal noise. Cells and neural circuits have powerful noise-resistance mechanisms, that are adequate protection against thermal noise and must therefore be more than sufficient to buffer against Heisenbergian effects. Other forms of quantum indeterminism must be considered, because these can be much greater than Heisenbergian uncertainty, but these have not so far been shown to play a role in the brain.     

Prospective memory training in older adults and its relevance for successful aging

In research on cognitive plasticity, two training approaches have been established: (1) training of strategies to improve performance in a given task (e.g., encoding strategies to improve episodic memory performance) and (2) training of basic cognitive processes (e.g., working memory, inhibition) that underlie a range of more complex cognitive tasks (e.g., planning) to improve both the training target and the complex transfer tasks. Strategy training aims to compensate or circumvent limitations in underlying processes, while process training attempts to augment or to restore these processes. Although research on both approaches has produced some promising findings, results are still heterogeneous and the impact of most training regimes for everyday life is unknown. We, therefore, discuss recent proposals of training regimes aiming to improve prospective memory (i.e., forming and realizing delayed intentions) as this type of complex cognition is highly relevant for independent living. Furthermore, prospective memory is associated with working memory and executive functions and age-related decline is widely reported. We review initial evidence suggesting that both training regimes (i.e., strategy and/or process training) can successfully be applied to improve prospective memory. Conceptual and methodological implications of the findings for research on age-related prospective memory and for training research in general are discussed.     

Singular Clues to Causality and Their Use in Human Causal Judgment

It is argued that causal understanding originates in experiences of acting on objects. Such experiences have consistent features that can be used as clues to causal identification and judgment. These are singular clues, meaning that they can be detected in single instances. A catalog of 14 singular clues is proposed. The clues function as heuristics for generating causal judgments under uncertainty and are a pervasive source of bias in causal judgment. More sophisticated clues such as mechanism clues and repeated interventions are derived from the 14. Research on the use of empirical information and conditional probabilities to identify causes has used scenarios in which several of the clues are present, and the use of empirical association information for causal judgment depends on the presence of singular clues. It is the singular clues and their origin that are basic to causal understanding, not multiple instance clues such as empirical association, contingency, and conditional probabilities.     

A Call for an Unbiased Search for Moderators in Disfluency Research: Reply to Oppenheimer and Alter (2014)

In a commentary to our article, Oppenheimer and Alter stressed the importance of searching for moderators in disfluency research. We agree, but we would like to clarify two issues. First, unlike Oppenheimer and Alter, we assume that learner characteristics might indeed moderate the effects of disfluency. Second, conclusions concerning the impact of disfluency in educational settings might be biased because of the file‐drawer problem. To counteract this possibility, we want to encourage other researchers to publish their studies––regardless of whether they found (positive) effects of disfluency or not. Until then, any recommendation concerning the use of disfluency as an educational intervention seems premature.     

The Effect of Retrieval Practice in Primary School Vocabulary Learning

The testing effect refers to the finding that retrieval practice leads to better long‐term retention than additional study of course material. In the present study, we examined whether this finding generalizes to primary school vocabulary learning. We also manipulated the word learning context. Children were introduced to 20 words by listening to a story in which novel words were embedded (story condition) or by listening to isolated words (word pairs condition). The children practised the meaning of 10 words by retrieval practice and 10 words by restudy. After 1 week, they completed a cued recall test and a multiple choice test. Words learned by retrieval practice were recalled better than words learned by additional study, but there was no difference in recognition. Furthermore, the children in the word pairs condition outperformed the children in the story condition. These results show that retrieval practice may improve vocabulary learning in children.

On the Role of Specific Emotions in Autonomous and Controlled Motivated Behaviour

In the present study, we study the effect of four specific emotions (i.e. happiness, relaxation, depression, and anxiety) on autonomous and controlled motivated behaviour. Drawing on the componential approach to emotions, we argue that because different emotions have a different action readiness—the readiness to engage with the environment—they also have a different impact on autonomous and controlled motivated behaviour. To test this hypothesis, we performed two studies. In the first one, 50 participants took part in an experience sampling study in which they reported their emotions (happiness, relaxation, depression, and anxiety) and autonomous and controlled motivated behaviour 10 times a day for 7 consecutive days. In the second study, 217 students participated in a lab experiment in which we studied the effect of induced anxiety, depression, happiness, and relaxation on autonomous motivated behaviour. The results showed how specific emotions predict autonomous motivated behaviour and that the relationship between the different emotions and autonomous motivated behaviour depends on the emotion under study. By doing so, we demonstrated the important role of emotions in the elicitation of autonomous motivated behaviour. Copyright © 2014 European Association of Personality Psychology
