Longitudinal evidence linking processing speed to the development of reasoning

Age‐related change in processing speed has been linked directly to increases in reasoning as well as indirectly via increases in the capacity of working memory (WM). Most of the evidence linking change in speed to reasoning has come from cross‐sectional research; in this article we present the findings from a 2½‐year longitudinal study of 277 6‐ to‐13‐year‐olds. On three occasions, speed of information processing was assessed with Visual Matching and Cross Out; WM was assessed with reading, listening, backward digit, alphabet, and operation span tasks; and nonverbal reasoning was assessed with Raven's progressive matrices. The results provided consistent evidence of direct links from processing speed to reasoning but inconsistent evidence for indirect links from speed to WM to reasoning. These findings suggest that variations in processing speed may constrain the development of reasoning, directly and perhaps indirectly.

Decision making in the prisoner's dilemma game: The effect of exit on cooperation and social welfare

The prisoner's dilemma game is a mixed‐motive game that offers two players the simultaneous choice between a cooperative and a defective alternative. An often neglected aspect of such a binary‐choice game, however, is that in many real‐life encounters, people can choose not only to cooperate or defect, but they also have a third option: to exit the social dilemma. Although in the literature a consensus has emerged that the addition of an exit opportunity benefits cooperation, there is only scant research into its effect on social welfare. In order to allow a direct comparison of cooperation rates and welfare levels across binary‐choice and trinary‐choice games, in this study, we used a design in which the same participants played similar games with and without an exit option (i.e., a within‐subjects design), and this in a range of structural variations. The findings of our study indicated that the aggregated outcome of both players is generally lower in games with an exit option than in games without an exit option. Moreover, our results showed that the efficiency of the exit option strongly depends on the specific outcome structure of the game (in terms of its endowment size, (a)symmetry, and level of noncorrespondence). In the discussion, it is argued that the implementation of an exit option as a strategy to increase social welfare should be critically assessed.     

Learning to read in Chinese: Evidence for reciprocal relationships between word reading and oral language skills

This study investigates the longitudinal predictors of the development of Chinese word reading skills and potential bidirectional relationships between Chinese word reading and oral language skills. We examine, in a 2‐year longitudinal study, a wide range of theoretically important predictors (phonological awareness, tone awareness, morphological awareness, visual skills, rapid automatized naming, Pinyin knowledge, and vocabulary knowledge) of reading in 143 primary‐school children living in mainland China. Initial levels of reading were predicted by vocabulary knowledge, phonological awareness, and visual discrimination skills. Only initial reading levels predicted growth in reading. Initial reading also predicted growth in vocabulary knowledge and morphological construction. This pattern demonstrates that the early stages of learning to read in Chinese places demands on semantic (vocabulary) and visual skills in addition to phonological skills. Furthermore, early levels of word reading predict the growth of vocabulary knowledge and morphological awareness suggesting that the development of these oral language skills is facilitated by learning to read.     

Multiple value dimensions spill‐over—An experimental approach in a consumption system comprising a product and a service

Through the customer's eyes, wireless telecommunications are a typical example of a so‐called consumption system, comprising a product and a service subsystem. People consume an entity in which multiple value perceptions from both subsystems (wireless service and cell phone) are gained and affect attitudes, intentions and future behaviour within and across the subsystems. Value perceptions are gained along the dimensions of functionality, economic aspects, emotions and social facets, regarding both service and product. Some of those value perceptions spill over, from product to service and vice versa, while others do not. Those that spill over affect value perceptions and loyalty intentions in the other subsystem. These results provide the basis for deriving practical implications for the marketing management of firms operating in such a consumption system. Given the presence of spill‐over effects, both parties involved are advised to revise their marketing activities accordingly. Copyright © 2017 John Wiley & Sons, Ltd.     

Facilitating Creative Idea Selection: The Combined Effects of Self-Affirmation,Promotion Focus and Positive Affect

Generating creative ideas in a brainstorm session `is a crucial part of innovation. However, for actual implementation, the most creative ideas must be selected from a pool of ideas. To date, idea selection has remained relatively unexplored and validated instruments to measure idea selection performance are not systematically employed. This study aimed to improve creative idea selection performance in a field study. In this study, an idea pool of 18 ideas was used, and participants had to select the 5 most creative ideas from the idea pool. Right before participants performed the idea selection task, in the experimental condition, a promotion focus and positive affect was induced in combination with a self-affirmation task. Participants in the control condition performed corresponding filler tasks. The selection of the 5 most creative ideas from the idea pool of 18 ideas was performed individually. Participants in the experimental condition selected ideas that were more creative than did participants in the control condition. These findings provide first evidence that the selection of creative ideas can be enhanced through a combined induction of promotion-focus, positive mood and self-affirmation.     

Training with anxiety: short- and long-term effects on police officers’ shooting behavior under pressure

We investigated short- and long-term effects of training with anxiety on police officers’ shooting behavior under pressure. Using a pretest, posttest, and retention test design, 27 police officers executed a shooting exercise against an opponent that did (high anxiety) or did not (low anxiety) shoot back using colored soap cartridges. During the training sessions, the experimental group practiced with anxiety and the control group practiced without anxiety. At the pretest, anxiety had a negative effect on shot accuracy for both groups. At the posttest, shot accuracy of the experimental group no longer deteriorated under anxiety, while shot accuracy of the control group was still equally affected. At the retention test, 4 months after training, positive results for the experimental group remained present, indicating that training with anxiety may have positive short- and long-term effects on police officers’ shot accuracy under pressure. Additional analyses showed that these effects are potentially related to changes in visual attention on task-relevant information.     

Driving in dangerous territory: Complexity and road-characteristics influence attentional demand

Car driving related attentional demands fluctuate according to route complexity and are found to be highly associated with motor-vehicle collisions (MVCs). The purpose of the current study was to explore the inherent attentional demands of scenarios that approximate common crash configurations. Sixty drivers completed a series of 20 simulated driving scenarios incorporating either rear-end or crossing path situations. For each scenario, the complexity of the driving environment was systematically manipulated in terms of vehicle handling and information processing elements. The attentional demands of each scenario were assessed by means of a peripheral detection task (PDT) as well as through a subjective measure of overall difficulty. Our results showed a reduction in PDT performance at intersections where information processing is increased as well as when handling maneuvers behind a lead vehicle were required. The results point to the appropriateness of the PDT as a sensitive measure of cognitive workload. The implications of these findings for future research and safety initiatives are discussed.     

Does materialism predict racism? materialism as a distinctive social attitude and a predictor of prejudice

Previous research reported that Right‐Wing Authoritarianism (RWA) and Social Dominance Orientation (SDO) constitute the individual's ideological space and are strong dispositional determinants of racism. In the present study, materialism was examined as a third social attitude and a potential predictor of racism. In a student (N = 183) and heterogeneous adult sample (N = 176) analyses revealed that RWA, SDO and materialism constitute three separate dimensions and that each of them explains a unique part of the variance in racism. In addition, Structural Equation Modelling showed that the relationship between materialism and racism was largely mediated by selfish motives. In the discussion we go further into the role of materialism as a third social attitudinal dimension. Copyright © 2006 John Wiley & Sons, Ltd.     

Emotionally controlled decision-making and a gene variant related to serotonin synthesis in women with borderline personality disorder

The Iowa Gambling Task (IGT) was used to examine (i) social decision-making in women with borderline personality disorder (BPD), and (ii) the relationship between impaired decision-making and the tryptophan hydroxylase-1 (TPH-1) gene, involved in serotonin synthesis. Forty-two women with BPD and a history of suicide attempts were genotyped, and the frequency of a TPH-1 haplotype previously uniquely associated with BPD was calculated. The BPD group scored significantly lower than a control group in the IGT. Furthermore, the TPH-1 haplotype displayed a significantly higher frequency in BPD participants with impaired decision making, compared to BPD participants with normal scores. These findings suggest that impaired decision-making as determined by the IGT is a feature of BPD and may be (i) associated with serotonin dysfunction, and (ii) possibly relevant for suicidal behavior.     

Separating ability from need: clarifying the dimensional structure of the Need for Closure Scale

The validity of the Need for Closure Scale (NFCS) has recently been debated in the research literature. In the present study, it is argued that the traditional Decisiveness scale primarily taps ability content instead of the hypothesized motivational need; therefore, new items that explicitly probe the need for quick and unambiguous answers were developed. It was shown that these need items form a reliable scale (Study 1); were predictive of the seizing process over and beyond ability, whereas the old Decisiveness scale was not (Study 2); and were sensitive to experimentally manipulated levels of task motivation (Study 3). Finally, a reassembled NFCS with the new items replacing the traditional Decisiveness items showed superior fit as a unidimensional model. In the Discussion, it is argued that the specific position of Decisiveness is due to its particular operationalization, not to its theoretical status.
