Examining the effects of group‐based instruction on emergent second‐language skills in young children

The present study evaluated the emergence of second‐language intraverbals in typically developing young children following a small‐group teaching intervention. Choral responding was employed with a group of 6 primary school children (5‐6 years old) to teach first‐language tacts (e.g., “What is this in English?” [“Hospital”]) and related second‐language tacts (e.g., “What is this in Welsh?” [“Ysbyty”]). A multiple‐probe design across stimulus sets was used to evaluate subsequent emergence of untrained first‐to‐second‐language derived intraverbals (e.g., “What is hospital in Welsh?” [“Ysbyty”]) and untrained second‐to‐first‐language intraverbals (e.g.,”What is ysbyty in English?” [“Hospital”]). Data indicated that the choral responding intervention produced robust increases in derived intraverbal relations for 3 of the 6 participants.     

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.     

The Mobilizing Effect of Right‐Wing Ideological Climates: Cross‐Level Interaction Effects on Different Types of Outgroup Attitudes

The present research investigated a multilevel person‐context interactionist framework for the relationship between right‐wing ideologies and prejudice across two large, representative samples (Study 1: European Social Survey: N = 56,752; Study 2: World Values Survey: N = 74,042). Across three different operationalizations of right‐wing ideology, two contextual levels (regional and national) of right‐wing climate, and three types of outgroup attitudes (i.e., age‐, ethnicity‐, and gender‐based), the analyses consistently revealed cross‐level interactions, showing a strong association between right‐wing attitudes and negative outgroup attitudes at the individual level in contexts with a low right‐wing climate, whereas this relationship is weaker and often even absent in contexts with a high right‐wing climate. These cross‐level interactions remained significant after controlling for statistical artefacts (i.e., restriction of range and outliers). The authors propose norm setting as the mobilizing mechanism through which a right‐wing climate develops and curbs the influence of individual right‐wing social‐ideological attitudes on outgroup attitudes.     

Observers' Language Proficiencies and the Detection of Non‐native Speakers' Deception

We examined whether observers' language proficiencies affected their abilities to detect native and non‐native speakers' deception. Native and non‐native English speakers were videotaped as they either lied or told the truth about having cheated on a test. A total of 284 laypersons—who were either native or non‐native English speakers themselves—viewed these videos and indicated whether they believed that the speakers were being truthful or deceptive. Observers were more accurate when judging native speakers than when judging non‐native speakers, suggesting that perceptual fluency aided deception detection. Although there was no effect of observers' language proficiencies on discrimination, their belief that interviewees were telling the truth increased with proficiency. On the whole, these findings suggest that non‐native speakers may be at greater risk of being incorrectly classified in forensic contexts.Copyright © 2017 John Wiley & Sons, Ltd.     

Cognitive and attentional functioning in adolescents and young adults with Tetralogy of Fallot and d-transposition of the great arteries

The objective of this study is to investigate cognitive and attentional function in adolescents and young adults with operated congenital heart disease. Previous research has indicated that children with congenital heart disease have deficits in broad areas of cognitive function. However, less attention has been given to survivors as they grow into adolescence and early adulthood. The participants were 18 non-syndromic adolescents and young adults with tetralogy of Fallot and d-transposition of the great arteries that required cardiac surgery before the age of 5 years, and 18 healthy, unaffected siblings (11–22 years of age for both groups). Cases with congenital heart disease and their siblings were administered Wechsler Intelligence scales and reported attention problems using the Achenbach System of Empirically Based Assessments. Cases were compared to both healthy siblings and established norms. Cases performed significantly lower than siblings on full scale IQ and processing speed, and significantly lower than norms on perceptual reasoning. Cases also reported more attention problems compared to both siblings and norms. Effect sizes varied with medium-to-large effects for processing speed, perceptual reasoning, working memory, and attention problems. Findings suggest that neurocognitive function may continue to be affected for congenital heart disease survivors in adolescence and young adulthood, and that comparisons to established norms may underestimate neurocognitive vulnerabilities.     

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.     

Is scent‐enhanced memory immune to retroactive interference?

Research shows that scent enhances memory for associated information. Current debate centers around scent's immunity to “retroactive interference,” i.e., reduced memory for earlier-learned information after exposure to additional, subsequently-learned information. This paper demonstrates that scent-enhanced memory is indeed prone to retroactive interference, but that some of the information lost is restored using a scent-based retrieval cue. Two process explanations for interference effects are proposed, with the evidence providing more support for an inhibition rather than a response competition explanation. The results enhance our understanding of the encoding and retrieval of olfactory information from long-term memory, and reasons why interference occurs.
