Preschoolers affect others' reputations through prosocial gossip

Providing evaluative information to others about absent third parties helps them to identify cooperators and avoid cheaters. Here, we show that 5‐year‐olds, but not 3‐year‐olds, reliably engage in such prosocial gossip. In an experimental setting, 5‐year‐old children spontaneously offered relevant reputational information to guide a peer towards a cooperative partner. Three‐year‐old children offered such evaluative information only rarely, although they still showed a willingness to inform in a non‐evaluative manner. A follow‐up study revealed that one component involved in this age difference is children's developing ability to provide justifications. The current results extend previous work on young children's tendency to manage their own reputation by showing that preschoolers also influence others' reputations via gossip.     

Posture and the emergence of manual skills

In this paper, we examine how infants’ natural manual and postural activities — what they prefer and do week by week — are related to developmental transitions in reaching skill and its neuromuscular control. Using a dense, longitudinal design, we tracked the manual and postural activities of four infants in a natural, free‐play setting across the first year of life, and related these activities to two transitions in reaching as measured in a structured laboratory setting: the transition to reaching and the transition to stable reaching. Our data indicated that specific advances in the free‐play setting preceded both transitions. Head and upper torso control, the ability to extend the arm and hand to a distant target, and the ability to touch and grasp objects placed nearby were all precursors to the onset of reaching, whereas sitting independently was associated with the transition to stable reaching. We also found important individual variability in when these ‘components’ were in place, indicating that it is the ensemble of components that is essential, not the order in which they develop or the timing of their contribution. These findings suggest that subsequent experimental manipulations should be planned with respect to infants’ individual constellations of skills, rather than looking at only a single precursor to change.     

Parent-early adolescent relationship quality and problem behavior in Hungary,the Netherlands,India, and Iceland

Higher parent-child relationship quality has been associated with less internalizing and externalizing problem behavior. However, it remained less clear whether these associations are universal or depend on the country under investigation. Furthermore, fathers are still understudied, even though there is increasing evidence of their important role in early adolescent development. Our study compared the association of mother-child as well as father-child relationship quality with early adolescents’ problem behavior in four culturally different countries, namely Hungary (N = 293; M_age = 11.22; 53% boys), the Netherlands (N = 242; M_age = 11.20; 48% boys), India (N = 230; M_age = 10.68; 61% boys), and Iceland (N = 261; M_age = 10.90; 53% boys). Early adolescents filled out questionnaires in their classroom, assessing warmth and conflict with fathers and mothers and internalizing and externalizing problem behavior. Stepwise multi-group path analysis demonstrated no cross-cultural differences in associations between quality of the parent-child relationship and problem behavior. We did not find any effects of maternal or paternal warmth. However, across samples conflict with mothers was associated with more internalizing and externalizing problem behavior, and conflict with fathers was associated with more externalizing problem behavior. Our findings highlight the need to target conflict with both fathers and mothers in interventions across different countries, especially when addressing externalizing problem behavior.     

Adolescents and handheld advertising: The roles of brand familiarity and smartphone attachment in the processing of mobile advergames

Many adolescents are inseparable from their smartphones on which they are often confronted with covert advertising‐like mobile advergames. This study explores the roles of brand familiarity and smartphone attachment in adolescents’ abilities to recognize the commercial intent of advergames. Moreover, it considers the potential indirect effects of brand familiarity and smartphone attachment on the susceptibility of young consumers to mobile advergames. An experiment (N = 98) was conducted, which showed that brand familiarity moderates the effect of playing advergames on the recognition of the commercial intent of advergames. Furthermore, smartphone attachment was found to facilitate the recognition of the commercial intent of advergames, such that adolescents who experienced higher levels of smartphone attachment (when compared to lower levels) were better able to differentiate between advergames and non‐commercial games (games without advertising). Interestingly, no association between smartphone attachment and brand responses were found—suggesting that smartphone attachment did not affect adolescents’ compliance with the advertised message.     

Analysis of the perceptual learning effect in flavour aversion learning: Evidence for stimulus differentiation

Rats received exposure to two compound flavours, AX and BX, where A and B were sucrose and saline and X was acid. For group intermixed (I), exposure consisted of alternating trials with AX and BX; group blocked (B) received a block of AX trials and a separate block of BX trials. Experiment 1 showed that generalization to BX after conditioning with AX was less profound in group I than in group B. Separate examination of the elements of the compound showed that the source of this difference lay in the strength acquired by the X element. X acquired less strength in group I than in group B (Experiments 1 and 2), whereas for the A element (Experiments 3 and 4) the reverse pattern was obtained. These results support the proposal that the perceptual learning effect (restricted generalization from AX to BX in group I) depends on a process that enhances the effectiveness of unique stimulus elements (A and B) and reduces that of common elements (such as X).

Intentional artificial grammar learning: When does it work?

Actively searching for the rules of an artificial grammar has often been shown to produce no more knowledge than memorising exemplars without knowing that they have been generated by a grammar. The present study investigated whether this ineffectiveness of intentional learning could be overcome by removing dual task demands and providing participants with more specific instructions. The results only showed a positive effect of learning intentionally for participants specifically instructed to find out which letters are allowed to follow each other. These participants were also unaffected by a salient feature. In contrast, for participants who did not know what kind of structure to expect, intentional learning was not more effective than incidental learning and knowledge acquisition was guided by salience.
