The role of executive processes in prospective memory tasks

Prospective remembering refers to remembering and acting on behavioural intentions. Three experiments tested the hypothesis that prospective remembering requires the availability of executive processes. It was expected that this is more important when intentions are stated in categorical terms. Type of instruction (specific versus categorical), typicality of the cue in relation to the category specified, and executive load were manipulated. Results showed a general benefit of specific instructions. Furthermore, with categorical instructions, performance was better with typical cues. Although the data suggested that executive processes are responsible for the processing of cues, the load manipulation had no significant effect on the prospective memory measure. Thus, no evidence was found for the hypothesis that prospective remembering requires the availability of executive processes. It is argued that it is a matter of strategic choice whether executive processes are deployed: One does not need to monitor for cues but can choose to rely on bottom‐up processes. Monitoring may be sufficient, but not necessary for successful prospective remembering.     

The Contribution of Personality Traits,Motivation, Academic Risk-Taking and Metacognition to the Creative Ability in Mathematics

The purpose of this study was to investigate the extent to which personality traits, motivation, academic risk-taking, and metacognition explain the mathematical creative ability of high school students. The participants were 217 9th-grade students that were exceptionally high achievers. The participants responded to a set of measures about personality traits, motivation, academic risk-taking, metacognition, and creative ability in mathematics. The results revealed that although openness to experience and consciousness were significantly correlated with creative ability in mathematics, extraversion, agreeableness, and neuroticism were not correlated with the creativity scores. Moreover, intrinsic goal orientation followed by openness to experience was the most significant predictor of mathematical creative ability. Academic risk-taking was not significantly correlated with creative ability. Although knowledge of cognition and regulation of cognition showed moderate correlations with creative ability in mathematics, they failed to predict creative ability.     

Consumer style and health: The role of impulsive buying in unhealthy eating

Health psychologists have given surprisingly little attention to consumer behavior. This study focuses on the relationship between an impulsive consumer style and unhealthy eating. In a survey, moderate to strong correlations were found between low self-esteem, dispositional negative affect, impulse buying tendency, snacking habit, and eating disturbance propensity. Structural equation modeling was used to test a model of relations between these variables. Impulse buying tendency was strongly associated with snacking habit, which in turn was related to eating disturbance propensity. Impulse buying, though in itself a pleasurable activity, seemed driven by feelings of low self-esteem and dispositional negative affect. Low self-esteem had a direct link to eating disturbance propensity. The data fit a self-regulation explanation. The study demonstrates the relevance of consumer style for health-related behaviors.     

Conscientiousness and (un)healthy eating: The role of impulsive eating and age in the consumption of daily main meals

The present study aims to explore the relationship between conscientiousness and the consumption of healthy versus unhealthy main meals. Impulsive eating was tested as a mediator in this relationship, as well as direct effects of age on those constructs. A nationwide representative sample of 1,006 Norwegian adults (18–70 years) within a prospective design was used to test a theoretical model. The structural equation model (SEM), in combination with bootstrapping procedures in AMOS, was the principal analytical method. Conscientiousness was negatively associated with unhealthy and impulsive eating. Impulsive eating was a partial mediator between conscientiousness and unhealthy eating and a full mediator between conscientiousness and healthy eating. Age was positively correlated with conscientiousness and this relationship had an inverted U‐shape form. Finally, age was negatively associated with unhealthy and impulsive eating, and positively associated with healthy eating. This study confirmed the relevance of conscientiousness for healthy, unhealthy, and impulsive eating.     

Neural dissociation of phonological and visual attention span disorders in developmental dyslexia: FMRI evidence from two case reports

A dissociation between phonological and visual attention (VA) span disorders has been reported in dyslexic children. This study investigates whether this cognitively-based dissociation has a neurobiological counterpart through the investigation of two cases of developmental dyslexia. LL showed a phonological disorder but preserved VA span whereas FG exhibited the reverse pattern. During a phonological rhyme judgement task, LL showed decreased activation of the left inferior frontal gyrus whereas this region was activated at the level of the controls in FG. Conversely, during a visual categorization task, FG demonstrated decreased activation of the parietal lobules whereas these regions were activated in LL as in the controls. These contrasted patterns of brain activation thus mirror the cognitive disorders’ dissociation. These findings provide the first evidence for an association between distinct brain mechanisms and distinct cognitive deficits in developmental dyslexia, emphasizing the importance of taking into account the heterogeneity of the reading disorder.
