Teleo‐functional constraints on preschool children's reasoning about living things

These studies explore the degree to which preschool children employ teleological‐functional reasoning – reasoning based on the assumption of function and design – when making inferences about animal behavior. Using a triad induction method, Study 1 examined whether a sensitivity to biological function would lead children to overlook overall similarity and instead attend to relevant functional cues (in the presence of overall dissimilarity), as a basis for generalizing behavioral properties to unfamiliar animals. It found that, between 3 and 4 years of age, children, with increasing consistency, attend to functional features rather than overall similarity when drawing inferences about animal behavior. Children's ability to describe the relevance of functional adaptations to animal behavior also increased with age. Study 2 explored whether Study 1 findings might result from stimulus biases in favor of the function‐based choice. It found that children's attention shifted from functional features to overall similarity when generalizing labels rather than behaviors with the same triads. These results are discussed in relation to the development of biological knowledge.     

Improving the reliability of event-based laboratory tests of prospective memory

Laboratory tests of event-based prospective memory (ProM) require participants to perform actions in response to infrequent cues in a background task. We conducted three experiments to assess and improve the reliability of this popular procedure. In Experiment 1, we tested college students on 2 separate days and found that the alternate-forms reliability of ProM accuracy was quite low (r = .31), although general knowledge accuracy was more reliable (r= .89). In Experiment 2, a statistically significant difference in reliability emerged between conditions with a low (n = 6) versus a high (n = 30) number of ProM targets. Finally, lower ProM accuracy increased reliability in Experiment 3. Adopting these straightforward changes may enhance the search for individual differences in ProM.     

Time to get a new mountain? The role of function in children's conceptions of natural kinds

Prior research indicates that young children are promiscuously teleological, attributing purpose not only to artifacts, but also to living and non-living natural entities. This study further examines the role of function in children's reasoning about different object kinds by indirectly probing children's intuitions about what types of entities can be rendered functionless. Specifically, children were asked to decide whether entities that could no longer perform certain activities should be fixed/replaced (e.g. "Do you need to get a new one?"). Results reveal that young children broadly view both artificial and natural kinds that can no longer perform certain activities as needing to be fixed or replaced. These findings suggest that the teleo-functional bias not only influences children's explanatory preferences but also their category judgments.     

Aliens behaving badly: children's acquisition of novel purity-based morals

The traditional cognitive developmental perspective on moral acquisition posits that children actively construct moral beliefs by assessing the negative impacts of antisocial behaviors. This account is not easily applied to actions that are considered immoral despite lacking consequences for others' welfare. We studied the moralization of behaviors without tangible impacts, specifically examining the independent and joint roles of feelings and norms in children's acquisition of purity-based morals. Seven-year-olds were shown pictures of anthropomorphic aliens engaged in unfamiliar activities and were asked to judge whether these actions were wrong or OK. Relative to a control condition matched for valence and informational complexity, children made elevated wrongness judgments when they were either disgusted or led to believe that the behaviors were unnatural. However, it was only in a condition that included both disgust induction and information about unnaturalness that children exhibited robust tendencies to judge the actions as wrong. This research therefore demonstrates that feelings and norms work in concert such that purity morals are most readily acquired when both factors are involved. The implications for accounts of moral development are discussed.     

Children's Conformity When Acquiring Novel Conventions: The Case of Artifacts

Prior research focused on children's acquisition of arbitrary social conventions (e.g., object labels) has revealed that both 3- and 4-year-old children conform to majority opinion. Two studies explored whether children show similar conformist tendencies when making category-based judgments about a less socially arbitrary domain that offers an objective basis for judgment: object functions. Three- and 4-year-old children watched a video in which two informants disagreed with a lone dissenter on the function of a novel artifact. Children were asked to categorize the object by stating with whom they agreed. The plausibility of the majority's response was manipulated across test trials. Results demonstrated that children were more likely to agree with the majority when majority and minority opinions were equally plausible, especially when the majority demonstrated an overt consensus. However, 4-year-olds actively eschewed the majority opinion when it was implausible in context of the artifact's functional design. The current results indicate that expertise in a domain of conventional knowledge reduces conformist tendencies.     

Individual differences in metacognition: Evidence against a general metacognitive ability

Individual differences in metacognitive accuracy are generally thought to reflect differences in metacognitive ability. If so, memory monitoring performance should be consistent across different metacognitive tasks and show high test-retest reliability. Two experiments examined these possibilities, using four common metacognitive tasks: ease of learning judgments, feeling of knowing judgments, judgments of learning, and text comprehension monitoring. Alternate-forms correlations were computed for metacognitive accuracy (with a 1-week interval between tests). Although individual differences in memory and confidence were stable across both sessions and tasks, differences in metacognitive accuracy were not. These results pose considerable practical and theoretical challenges for metacognitive researchers.     

When does gender diversity enhance team performance? The dual need for visionary leadership and team tenure

Teams in organizations are becoming more gender diverse as women continue to participate more in the workforce than ever before. Prior theory and research indicate that the characteristics of the team influence whether gender diversity in a team is an asset or a detriment. As such, this research explores a contingency model of the relation between gender diversity and team performance and looks to understand conditions that make this relation positive or negative. Specifically, we examine how leader vision communication (i.e., visionary leadership) affects the relation between gender diversity and team performance. Results from a sample of 595 full-time employees across 106 teams in China indicate that leader vision communication moderates the relation between gender diversity and team performance such that when leader vision communication is low gender diversity decreases team performance and when leader vision communication is high gender diversity has no significant relation with team performance. We also test whether team tenure changes this relationship. Our results suggest that gender diversity improves team performance when both leader vision communication and team tenure are high. The findings in our sample demonstrate that gender diversity can help teams enhance performance, but only when the conditions are right for gender-diverse teams to flourish.     

Developmental Continuity in Teleo-Functional Explanation: Reasoning about Nature Among Romanian Romani Adults

Teleo-functional explanations account for objects in terms of purpose, helping us understand objects such as pencils (for writing) and body parts such as ears (for hearing). Western-educated adults restrict teleo-functional attributions to artifact, biological, and behavioral phenomena, considering such explanations less appropriate for nonliving natural entities. In contrast, children extend explanations of purpose to the nonliving natural domain. This cross-cultural study explores whether apparent restrictions in“promiscuous teleology” occur as a function of age and development, generally, or scientific literacy, more specifically. Using methodology from Kelemen (1999b Kelemen , D. ( 1999b ). Why are rocks pointy? Children's preference for teleo-functional explanations of the natural world . Developmental Psychology , 35 , 1440 – 1453 .[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]), two groups of adult Romanian Roma from the same community selected explanations for properties of biological and nonbiological natural entities; one group had little or no science training, the other was formally schooled. Compared to their schooled peers and to Western-educated American adults, nonschooled Romani adults were more likely to endorse purpose-based explanations of nonbiological natural entities. Findings challenge assumptions of fundamental conceptual discontinuities between children and adults.     

Rigidity of the far‐right? Motivated social cognition in a nationally representative sample of Hungarians on the eve of the far‐right breakthrough in the 2010 elections

We investigated the “rigidity of the right” hypothesis in the context of the far‐right breakthrough in the 2010 Hungarian parliamentary elections. This hypothesis suggests that psychological characteristics having to do with need for security and certainty attract people to a broad‐based right‐wing ideology. A nationally representative sample (N = 1000) in terms of age, gender and place of residence was collected by means of the random walking method and face‐to‐face interviews. Voters of JOBBIK (n = 124), the radically nationalist conservative far‐right party, scored lower on System Justifying Belief, Belief in a Just World (Global) and higher on Need for Cognition than other voters. Our results contradict the “rigidity of the right” hypothesis: JOBBIK voters scored, on many measures, opposite to what the hypothesis would predict.
