Perceptual symbols of creativity: Coldness elicits referential,warmth elicits relational creativity

Research in the cognitive and social psychological science has revealed the pervading relation between body and mind. Physical warmth leads people to perceive others as psychological closer to them and to be more generous towards others. More recently, physical warmth has also been implicated in the processing of information, specifically through perceiving relationships (via physical warmth) and contrasting from others (via coldness). In addition, social psychological work has linked social cues (such as mimicry and power cues) to creative performance. The present work integrates these two literatures, by providing an embodied model of creative performance through relational (warm = relational) and referential (cold = distant) processing. The authors predict and find that warm cues lead to greater creativity when 1) creating drawings, 2) categorizing objects, and 3) coming up with gifts for others. In contrast, cold cues lead to greater creativity, when 1) breaking set in a metaphor recognition task, 2) coming up with new pasta names, and 3) being abstract in coming up with gifts. Effects are found across different populations and age groups. The authors report implications for theory and discuss limitations of the present work.     

Norms of age of acquisition and concreteness for 30,000 Dutch words

Word processing studies increasingly make use of regression analyses based on large numbers of stimuli (the so-called megastudy approach) rather than experimental designs based on small factorial designs. This requires the availability of word features for many words. Following similar studies in English, we present and validate ratings of age of acquisition and concreteness for 30,000 Dutch words. These include nearly all lemmas language researchers are likely to be interested in. The ratings are freely available for research purposes.     

The association between children's numerical magnitude processing and mental multi-digit subtraction

Children apply various strategies to mentally solve multi-digit subtraction problems and the efficient use of some of them may depend more or less on numerical magnitude processing. For example, the indirect addition strategy (solving 72–67 as “how much do I have to add up to 67 to get 72?”), which is particularly efficient when the two given numbers are close to each other, requires to determine the proximity of these two numbers, a process that may depend on numerical magnitude processing. In the present study, children completed a numerical magnitude comparison task and a number line estimation task, both in a symbolic and nonsymbolic format, to measure their numerical magnitude processing. We administered a multi-digit subtraction task, in which half of the items were specifically designed to elicit indirect addition. Partial correlational analyses, controlling for intellectual ability and motor speed, revealed significant associations between numerical magnitude processing and mental multi-digit subtraction. Additional analyses indicated that numerical magnitude processing was particularly important for those items for which the use of indirect addition is expected to be most efficient. Although this association was observed for both symbolic and nonsymbolic tasks, the strongest associations were found for the symbolic format, and they seemed to be more prominent on numerical magnitude comparison than on number line estimation.     

When the mind wanders: Age-related differences between young and older adults

Interest in mind wandering (MW) has grown in recent years, but few studies have assessed this phenomenon in older adults. The aim of this study was to assess age-related differences between young, young–old and old–old adults in MW using two versions of the sustained attention to response task (SART), one perceptual and one semantic. Different indicators were examined (i.e., reported MW episodes and behavioral indices of MW such as response time latency and variability, incorrect response and omission errors). The relationship between MW, certain basic mechanisms of cognition (working memory, inhibition and processing speed), cognitive failures and intrusive thoughts in everyday life was also explored. Findings in both versions of the SART indicated that older adults reported a lower frequency of MW episodes than young adults, but some of the behavioral indices of MW (response time variability, incorrect response and omission errors) were higher in old–old adults. This seems to suggest that MW becomes less frequent with aging, but more pervasive and detrimental to performance. Our results also indicated that the role of age and cognitive mechanisms in explaining MW depends on the demands of the SART task considered.
