Testing alternative explanations of phantom decoy effects

Phantom decoys are alternatives that asymmetrically dominate a targeted alternative and yet lead to increased selection of the target when the decoy is declared to be unavailable. This effect is difficult to explain within most standard theoretical accounts of decoy effects. The current experiments tested between three explanations of this effect: (1) the relative advantage model based on loss aversion, (2) similarity substitution, and (3) range weighting. In Experiment 1, participants were presented trinary choice sets, with half of the sets containing a phantom decoy in one of five possible locations within the attribute space. Phantom decoy effects were robust across all decoy locations but one, and the pattern of effects most closely corresponded to predictions of the relative advantage model. Experiment 2 used a within‐subjects manipulation of the five phantom decoy locations. The overall pattern of effects most closely corresponded to predictions from the relative advantage model, as did the pattern for the group of participants who exhibited the strongest phantom decoy effects.

Priming interdependence affects processing of context information in causal inference—But not how you might think

Cultural mindset is related to performance on a variety of cognitive tasks. In particular, studies of both chronic and situationally-primed mindsets show that individuals with a relatively interdependent mindset (i.e., an emphasis on relationships and connections among individuals) are more sensitive to background contextual information than individuals with a more independent mindset. Two experiments tested whether priming cultural mindset would affect sensitivity to background causes in a contingency learning and causal inference task. Participants were primed (either independent or interdependent), and then saw complete contingency information on each of 12 trials for two cover stories in Experiment 1 (hiking causing skin rashes, severed brakes causing wrecked cars) and two additional cover stories in Experiment 2 (school deadlines causing stress, fertilizers causing plant growth). We expected that relative to independent-primed participants, those interdependent-primed would give more weight to the explicitly-presented data indicative of hidden alternative background causes, but they did not do so. In Experiment 1, interdependents gave less weight to the data indicative of hidden background causes for the car accident cover story and showed a decreased sensitivity to the contingencies for that story. In Experiment 2, interdependents placed less weight on the observable data for cover stories that supported more extra-experimental causes, while independents' sensitivity did not vary with these extra-experimental causes. Thus, interdependents were more sensitive to background causes not explicitly presented in the experiment, but this sensitivity hurt rather than improved their acquisition of the explicitly-presented contingency information.     

Culture: Copying,Compression, and Conventionality

Through cultural transmission, repeated learning by new individuals transforms cultural information, which tends to become increasingly compressible (Kirby, Cornish, & Smith, 2008 ; Smith, Tamariz, & Kirby, 2013 ). Existing diffusion chain studies include in their design two processes that could be responsible for this tendency: learning (storing patterns in memory) and reproducing (producing the patterns again). This paper manipulates the presence of learning in a simple iterated drawing design experiment. We find that learning seems to be the causal factor behind the increase in compressibility observed in the transmitted information, while reproducing is a source of random heritable innovations. Only a theory invoking these two aspects of cultural learning will be able to explain human culture's fundamental balance between stability and innovation.     

Can Culture Influence Body‐Specific Associations Between Space and Valence?

People implicitly associate positive ideas with their dominant side of space and negative ideas with their non‐dominant side. Right‐handers tend to associate “good” with “right” and “bad” with “left,” but left‐handers associate “bad” with “right” and “good” with “left.” Whereas right‐handers' implicit associations align with idioms in language and culture that link “good” with “right,” left‐handers' implicit associations go against them. Can cultural conventions modulate the body‐specific association between valence and left‐right space? Here, we compared people from Spanish and Moroccan cultures, which differ in the strength of taboos against the use of the left hand, and therefore in their preference for the right. Results showed stronger explicit associations between space and valence in Moroccan participants than in Spaniards, but they did not show any increased tendency for right‐handed Moroccans to associate “good” with “right” implicitly. Despite differences in cultural conventions between Spaniards and Moroccans, we find no evidence for a cross‐cultural difference in the implicit association between space and valence, which appears to depend on patterns of bodily experience.     

Children’s scale errors and object processing: Early evidence for cross-cultural differences

Scale errors are observed when young children make mistakes by attempting to put their bodies into miniature versions of everyday objects. Such errors have been argued to arise from children’s insufficient integration of size into their object representations. The current study investigated whether Japanese and UK children’s (18–24 months old, N = 80) visual exploration in a categorization task related to their scale error production. UK children who showed greater local processing made more scale errors, whereas Japanese children, who overall showed greater global processing, showed no such relationship. These results raise the possibility that children’s suppression of scale errors emerges not from attention to size per se, but from a critical integration of global (i.e., size) and local (i.e., object features) information during object processing, and provide evidence that this mechanism differs cross-culturally.     

Historical change, cultural learning, and cognitive representation in Zinacantec Maya children

Against the background of an unchanging sequence of representational development, we demonstrate that implicit processes of learning and cognition can change from one historical period to another. One generation of Zinacantec Maya children was studied in 1969 and 1970, the next generation in 1991 and 1993. In the intervening two decades, the community, located in Chiapas, Mexico, was involved in a transition from an economy based primarily on subsistence and agriculture to an economy based primarily on money and commerce. A naturalistic study of weaving apprenticeship and an experimental study of visual representation showed that the ecological transition was linked to greater emphasis on independent cultural learning, abstract representation, and innovation, and, correlatively, a movement away from scaffolded guidance, detail-oriented representation, and imitative representational strategies. These changes constituted automatic adaptations with an implicit nature. In addition, historical variability in implicit modes of cultural apprenticeship predicted shifts in implicit processes of child and adolescent cognition. In sum, socialization and development are not fixed but adapt, in a coordinated way, to changing ecological conditions.     

Positive affect as a moderator of liking effects on trust and attraction

Attitude similarity effects on attraction appear to be mediated sequentially by positive affect, inferred attraction, and trust. That is, the first two supposedly distal mediators influence each other in building trust, a mediator proximal to attraction. However, the correlational nature of data reported heretofore precludes definitive conclusions about sequential dependency between the two distal mediators. In the research reported, therefore, the authors manipulated positive affect in the participants (Time 1) and liking of the partner for them (Time 2), and measured trust before attraction. As predicted, liking effects on trust and attraction were stronger when positive affect in the participants was high than when it was low. Importantly, the interaction effect in trust fully mediated the interaction effect in attraction.

Narrative and discursive perspectives on athletic identity: Past,present, and future

ObjectivesThe dominant role-based conceptualisations of athletic identity have recently been challenged in favour of theoretical perspectives that view identity as a complex cultural construction. In the present study, we analysed empirical studies on athletic identity positioned in narrative and discursive approaches to gain an insight into the use and subsequent contribution of these approaches to knowledge production in this research topic.Design and methodA total of 23 articles, of which 18 narrative studies and five discursive studies, were identified in a systematic literature search. We used the meta-study method to analyse these studies in terms of basic assumptions, methodologies, and findings.ResultsEarly narrative studies focused on biographical disruption in career termination and/or severe injury, whereas more recent studies examined the impact of different identity narratives on athletes' well-being and career decisions. Discursive studies examined the multiple ways in which dominant understandings of gender, age, and the athletic body are (re)produced and normalised within sporting cultures and institutions and can act to constrain athletes to certain identities and practices. Both approaches highlighted that elite sport culture offers limited narrative resources or subject positions for athletes, and can endanger athletes' well-being if they are unable to comply with dominant ideals of being an athlete.ConclusionsNarrative and discursive approaches have advanced understandings of the constitutive role of sporting culture in athletic identity formation. Future research should continue exploring athletic identity in various physical cultural contexts and seek to identify alternative narratives and discourses that may enable athletes to construct more adaptive identities.
