Adults' attraction to rare objects has been variously attributed to fundamental biases related to resource availability, self-related needs, or beliefs about social and market forces. The current three studies investigated the scarcity bias in 11- and 14-month-old infants, and 3- to 6-year-old children (N = 129). With slight methodological…

This study investigated 3- to 11-year-old US children's (N = 348) perceptions of access to resources, social group preferences, and resource distribution decisions and reasoning when hypothetical peers differed in social class (poor or rich) and race (Black or White). Data were collected in 2019. The sample reflected the region where data were…

One of the core functions of explanation is to support prediction and generalization. However, some explanations license a broader range of predictions than others. For instance, an explanation about biology could be presented as applying to a specific case (e.g., "this bear") or more generally across "all animals." The current…

Adults exhibit strong preferences when framing symmetrical relations. Adults prefer, for example, "A zebra is like a horse" to "A horse is like a zebra," and "The bicycle is near the building" to "The building is near the bicycle." This is because directional syntax requires more typical or prominent items…

Three experiments investigated 3-, 4-, and 5-year-olds' (N = 240) understanding that their future or "grown-up" preferences may differ from their current ones (self-future condition). This understanding was compared to children's understanding of the preferences of a grown-up (adult-now condition) or the grown-up preferences of…

Children prefer to learn from informants in consensus with one another. However, no research has examined whether this preference exists across cultures, and whether the race of the informants impacts that preference. In 2 studies, one hundred thirty-six 4- to 7-year-old European American and Taiwanese children demonstrated a systematic preference…

Children and adolescents evaluated group inclusion and exclusion in the context of generic and group-specific norms involving morality and social conventions. Participants ("N" = 381), aged 9.5 and 13.5 years, judged an in-group member's decision to deviate from the norms of the group, whom to include, and whether their personal…

To examine the relationship between visual attention in infancy and the stimulus variables of contour and numerosity, 2- and 4-month-olds were placed in three experimental conditions. The results showed that contour and numerosity, acting in tandem, are responsible for the age-complexity shift observed by previous investigators of infant…

Preschool and kindergarten nonconservers (N=114) were examined for their use of dimensions relevant to quantity in two conservation-of-substance tasks. The results were interpreted as being counter to Piaget's 4-step equilibration model of the development of compensation and conservation. (ST)

The preference for color or form as bases for similarity judgments among preschoolers (ages 2-5) and its relationship to the differentiation of form and color concepts as indexed by discrimination, identification, and labeling were investigated. (SB)

Cardinal-ordinal abilities and attentional preferences of kindergarten nonconservers, kindergarten conservers, and third grade conservers of number were compared by employing standarized versions of Piagetian cardinal-ordinal tasks and a triad preference task. (Author/JMB)

Results indicate that children's preferences were relatively stable over time. (Authors/MB)

Examines, in three experiments, infant sensitivity at 20, 30, and 36 weeks of age to 3-dimensional structure of a human form specified through biomechanical motions. Findings are interpreted as suggesting that infants, by 36 weeks of age, are extracting fundamental properties necessary for interpreting a point-light display as a person. (Author/BE)

This investigation also studied the relationship between gestational age and preferences for contour. (CB)

Results show that both kindergarten nonconservers and kindergarten conservers found height most salient. Third-grade conservers found quantity most salient but could easily attend to height and width. (Author/CB)
