The role of preschoolers' social understanding in evaluating the informativeness of causal interventions

Preschoolers use information from interventions, namely intentional actions, to make causal inferences. We asked whether children consider some interventions to be more informative than others based on two components of an actor’s knowledge state: whether an actor possesses causal knowledge, and whether an actor is allowed to use their knowledge in a given situation. Three- and four-year-olds saw a novel toy that activated in the presence of certain objects. Two actors, one knowledgeable about the toy and one ignorant, each tried to activate the toy with an object. In Experiment 1, either the actors chose objects or the child chose for them. In Experiment 2, the actors chose objects blindfolded. Objects were always placed on the toy simultaneously, and thus were equally associated with the effect. Preschoolers’ causal inferences favored the knowledgeable actor’s object only when he was allowed to choose it (Experiment 1). Thus, children consider both personal and situational constraints on knowledge when evaluating the informativeness of causal interventions.     

Preschoolers' understanding of knowing-that and knowing-how in the United States and Hong Kong

Two experiments on preschoolers' understanding of the effects of exposure on knowing-that and knowing-how were conducted with 3-, 4-, and 5-year-old children (N=388) in 2 locations: a small midwestern city in the United States and a suburban area of Hong Kong, China. By using both English- and Chinese-speaking samples, the authors examined differences in children's understanding of knowing-that and knowing-how as well as the impact of different types of linguistic markers on the understanding of these concepts. Across both studies, in both locations, and for judging the knowledge of self or of others, children's understanding for knowing-that preceded their understanding for knowing-how. Implications of these findings both for universal patterns of theory-of-mind development and for how culture may impact on that development are discussed.     

Infants' ability to connect gaze and emotional expression to intentional action

Four studies investigated whether and when infants connect information about an actor's affect and perception to their action. Arguably, this may be a crucial way in which infants come to recognize the intentional behaviors of others. In Study 1 an actor grasped one of two objects in a situation where cues from the actor's gaze and expression could serve to determine which object would be grasped, specifically the actor first looked at and emoted positively about one object but not the other. Twelve-month-olds, but not 8-month-olds, recognized that the actor was likely to grasp the object which she had visually regarded with positive affect. Studies 2, 3, and 4 replicated the main finding from Study 1 with 12- and 14-month-olds and included several contrasting conditions and controls. These studies provide evidence that the ability to use information about an adult's direction of gaze and emotional expression to predict action is both present, and developing at the end of the first year of life.     

Differences in early parent-child conversations about negative versus positive emotions: implications for the development of psychological understanding

The authors examined whether the quality and content of everyday parent-child conversations about negative emotions are the same or different from everyday talk about positive emotions. Extensive longitudinal speech samples of 6 children and their parents were analyzed for several critical features when the children were between 2 and 5 years of age. Results showed that children and parents talked about past emotions, the causes of emotions, and connections between emotions and other mental states at higher rates during conversations about negative emotions than during conversations about positive emotions. Discourse about negative emotions also included a larger emotion vocabulary, more open-ended questions, and more talk about other people. These differences appeared before the children's 3rd birthdays and remained consistent through the preschool years. The findings strengthen and clarify current understanding of young children's articulation and knowledge about people's minds, lives, and emotions.     

Status legitimizing beliefs predict positivity toward Whites who claim anti-White bias

Although Whites are increasingly likely to perceive themselves as victims of racial bias, research provides little insight into how anti-White bias claimants are perceived. Two studies examined whether Whites' endorsement of status legitimizing beliefs (SLBs) moderates their reactions toward White discrimination claimants. In Study 1, Whites who rejected SLBs reacted less favorably to an anti-White bias claimant relative to one who made a nondiscriminatory external claim, whereas Whites who endorsed SLBs expressed equally positive attitudes toward an anti-White bias claimant and a non-claimant. In Study 2, Whites who were not primed with status legitimizing beliefs displayed negative reactions toward an anti-White bias claimant compared to a non-claimant, whereas those primed with SLBs expressed more positive attitudes and a desire to help the anti-White bias claimant. Implications for affirmative action litigation are discussed.     

Neural correlates of belief- and desire-reasoning in 7- and 8-year-old children: an event-related potential study

Theory of mind requires belief‐ and desire‐understanding. Event‐related brain potential (ERP) research on belief‐ and desire‐reasoning in adults found mid‐frontal activations for both desires and beliefs, and selective right‐posterior activations only for beliefs. Developmentally, children understand desires before beliefs; thus, a critical question concerns whether neural specialization for belief‐reasoning exists in childhood or develops later. Neural activity was recorded as 7‐ and 8‐year‐olds (N = 18) performed the same diverse‐desires, diverse‐beliefs, and physical control tasks used in a previous adult ERP study. Like adults, mid‐frontal scalp activations were found for belief‐ and desire‐reasoning. Moreover, analyses using correct trials alone yielded selective right‐posterior activations for belief‐reasoning. Results suggest developmental links between increasingly accurate understanding of complex mental states and neural specialization supporting this understanding.     

Sex differences in peer responsiveness to suicide ideation

Two surveys assessing attitudes toward and beliefs about suicide were conducted with undergraduates. There were 473 participants in Survey I and 692 participants in Survey II. Sex differences were found in participants' receptivity to suicidal individuals, beliefs about the behavior of suicidal peers, attitudes concerning the worth of suicidal people, incidence of adolescent suicide, and morality of suicide. There was no sex difference in participants' own frequency or seriousness of suicide ideation or suicide attempts. Results are discussed in terms of hypotheses concerning traditional socialization of males and females, resulting in sex-role differentiation that may influence attitudes toward and beliefs about suicide.     

Cosmopolitanism,Occupancy and Political Self‐Determination

The brand of cosmopolitanism that Cécile Fabre develops in her excellent book, Cosmopolitan Peace, leaves room for qualifying groups to exercise political self‐determination. Important questions thus emerge regarding who is entitled to have a say in the group's self‐determination, questions that take on a heightened practical urgency in the wake of wars that cause massive migration. In this article, I call into question Fabre's contention that the descendants of unjust occupants necessarily acquire occupancy rights which entitle them to a say in the political self‐determination over the territory on which they currently reside.
