Preschool children's use of trait labels to make inductive inferences

One hundred one preschool children (ages 3 years 5 months to 4 years 10 months) participated in 3 studies examining the tendency to use verbal labels versus appearance information in making novel inductive inferences. A triad task analogous to that of S. A. Gelman and E. M. Markman (1986) was devised. Participants learned a different property for each of 2 children, and were asked which of the properties was true of a third child. One of the first 2 children was identified with the same label as the third child (e.g., both were labeled as shy) but looked different, and the other was identified with a different label than the third child but looked very similar. Results of Study 1 revealed that participants tended to use the trait labels, rather than superficial resemblance, in making psychological inferences. Studies 2 and 3 suggest that these results cannot be attributed to biases on the task. Study 4 provided a replication of the results of Study 1 in a context in which appearance information was explicitly pointed out and in which different trait labels were used.     

The Growth of Flexible Problem Solving: Preschool Children Use Changing Verbal Cues to Infer Multiple Word Meanings

Flexible induction is the adaptation of probabilistic inferences to changing problems. Young children's flexibility was tested in a word-learning task. Children 3 to 6 years old were told 3 novel words for each of several novel objects. Children generalized each word to other objects with the same body shape, the same material, or the same part as the first object. Each word was preceded by a different predicate (i.e., "looks like a ...," "is made of ...," or "has a ...") that implies a different attribute (shape, material, or part, respectively). Three-year-olds showed limited use of predicates to infer word meanings, and they used predicates from previous trials to infer the meanings of later words. 4- to 6-year-olds used predicate cues more consistently and made inferences that were implied by the most recent predicate cue. Notably, 3-year-olds performed near ceiling in a control task that eliminated the need to use probabilistic inductive cues (Experiment 3). The results suggest that flexibility develops as a function of (a) sensitivity to between-problem variability and indeterminacy and (b) ability to decontextualize the most recent verbal cue to guide of inductive inferences.     

Category label effects on Chinese children's inductive inferences: modulation by perceptual detail and category specificity

Inductive generalization of novel properties to same-category or similar-looking objects was studied in Chinese preschool children. The effects of category labels on generalizations were investigated by comparing basic-level labels, superordinate-level labels, and a control phrase applied to three kinds of stimulus materials: colored photographs (Experiment 1), realistic line drawings (Experiment 2), and cartoon-like line drawings (Experiment 3). No significant labeling effects were found for photos and realistic drawings, but there were significant effects for cartoon-like drawings. Children made mostly (>70%) category-based inferences about photographs whether or not labels were provided (Experiment 1). Children showed a bias toward category-based inferences about realistic drawings (Experiment 2) but did so only when labels were provided. Finally, children made mostly appearance-based generalizations for cartoon-like drawings (Experiment 3). However, labels (basic or superordinate level) reduced appearance-based responses. Labeling effects did not depend on having identical labels; however, identical superordinate labels were more effective than different basic-level labels for the least informative stimuli (i.e., cartoons). Thus, labels sometimes confirm the identity of ambiguous items. This evidence of labeling effects in Mandarin-speaking Chinese children extends previous findings beyond English-speaking children and shows that the effects are not narrowly culture and language specific.     

Children use nonverbal cues from an adult to evaluate peers

What factors contribute to children’s tendency to view individuals as having different traits and abilities? The present research tested whether young children are influenced by adults’ nonverbal behaviors when making inferences about peers. In Study 1, participants (aged 5–6 years) viewed multiple videos of interactions between a “teacher” and two “students”; all individuals were unfamiliar to participants. In each clip, the students behaved similarly, but the teacher did not: She either smiled, nodded, touched, or shook her head at one student, and she looked at the other student with a neutral expression. In Study 1, children tended to infer that students who received more positive behaviors from the teacher were smarter, nicer, and stronger. Study 2 pitted differences in the teacher’s behavior against differences in the students’ performance. When asked who was smarter, children selected lower-performing students who received more positive nonverbal cues from the teacher rather than higher-performing students who received less positive cues. These findings indicate that an authority figure’s nonverbal behaviors can influence children’s inferences about others and shed light on one mechanism guiding young children’s evaluations of people in their social world.     

Gender differences in remembering and inferring spatial distances

The abilities of males and females to make spatial inferences were compared. Spatial inference is concerned with the ability to work out new spatial information from memory. In two experiments, participants had to study line drawings depicting shapes linked either by straight or meandering lines. Afterwards, they had to remember the straight-line distances or to infer the straight-line distances. Several spatial abilities were also assessed: perceptual discrimination, mental rotation, and visuo-spatial working memory span. The results showed that males outperformed females in spatial inference and mental rotation. Experiment 2 extended the study to old people. The results replicated and clarified those obtained in Experiment 1. Spatial inference and mental rotation showed age-related and gender-related differences; in addition, age reduced the visuo-spatial memory span. Overall, the findings suggest that gender differences favouring males are maximised with tasks requiring active processing and strategic control of metric information.

Speaker reliability guides children's inductive inferences about novel properties

Prior work shows that children can make inductive inferences about objects based on their labels rather than their appearance (Gelman, 2003). A separate line of research shows that children's trust in a speaker's label is selective. Children accept labels from a reliable speaker over an unreliable speaker (e.g., Koenig & Harris, 2005). In the current paper, we tested whether 3- and 5-year-old children attend to speaker reliability when they make inductive inferences about a non-obvious property of a novel artifact based on its label. Children were more likely to use a reliable speaker's label than an unreliable speaker's label when making inductive inferences. Thus, children not only prefer to learn from reliable speakers, they are also more likely to use information from reliable speakers as the basis for future inferences. The findings are discussed in light of the debate between a similarity-driven and a label-driven approach to inductive inferences.     

Carrot-Eaters and Creature-Believers: The Effects of Lexicalization on Children's Inferences About SocialCategories

This article examines how language affects children's inferences about novel social categories. We hypothesized that lexicalization (using a noun label to refer to someone who possesses a certain property) would influence children's inferences about other people. Specifically, we hypothesized that when a property is lexicalized, it is thought to be more stable over time and over contexts. One hundred fifteen children (5- and 7-year-olds) learned about a characteristic of a hypothetical person (e.g., "Rose eats a lot of carrots"). Half the children were told a noun label for each character (e.g., "She is a carrot-eater"), whereas half heard a verbal predicate (e.g., "She eats carrots whenever she can"). The children judged characteristics as significantly more stable over time and over contexts when the characteristics were referred to by a noun than when they were referred to by a verbal predicate. Lexicalization (in the form of a noun) provides important information to children regarding the stability of personal characteristics.     

The effects of narrative context on French verbal inflections: A developmental perspective

This experiment examines how narrative context affects French subjects' selection of past imperfective (imparfait) vs. perfective inflections with different predicate types. Adults and 10-year-old children were asked to inflect verbs presented in their written infinitive form in two conditions: (a) in isolated sentences; (b) embedded in the beginning, middle, or end of narratives. Regardless of conditions, the adults rarely used theimparfait with punctual resultative predicates. In both conditions, the frequency ofimparfait was high with durative predicates, particularly with aresultative ones, but it varied with position in the narratives, being highest at the beginning and lowest at the end. Although the children also used the imparfait frequently with durative predicates, they overgeneralized it to punctual resultative ones, regardless of conditions and of positions. These results show that adult uses of the imperfective/perfective distinction are determined by both predicate properties and grounding in narrative context. The children are less sensitive to some predicate properties than the adults and they do not differentiate imperfective/perfective aspect consistently as a function of discourse context.     

PHYSICAL ACTIVITY IN HOMES 13 TEACHING EMPATHY SKILLS TO CHILDREN WITH AUTISM

The purpose of this study was to teach empathetic responding to 4 children with autism. Instructors presented vignettes with dolls and puppets demonstrating various types of affect and used prompt delay, modeling, manual prompts, behavioral rehearsals, and reinforcement to teach participants to perform empathy responses. Increases in empathetic responding occurred systematically with the introduction of treatment across all participants and response categories. Furthermore, responding generalized from training to nontraining probe stimuli for all participants. Generalization occurred from dolls and puppets to actual people in a nontraining setting for 2 participants. Generalization was observed initially to the nontraining people and setting for the other participants, but responding subsequently decreased to baseline levels. Introduction of treatment in this setting produced rapid acquisition of target skills.     

Body-size stigmatization by preschool girls: In a doll's world,it is good to be “Barbie”

A number of studies have measured body size stigmatization, that is, the assigning of negative characteristics to individuals who are considered fat, in samples of children as young as preschool-age. The results of such studies are fairly consistent, but may be criticized for the abstract nature of the line drawings typically used as test stimuli. In the present study the utility of using toy dolls to gauge young girls’ views toward different body shapes was assessed. Forty girls ages 3½–5½ were asked to assign various traits to one of three dolls (thin, average, and fat). As with previous work, responses fell out in a stereotypical pattern, with the positive characteristics attributed most often to the thin or average doll and all of the negative characteristics most often to the fat doll. The strengths and weaknesses of this doll paradigm in studies of body-size stigmatization by young children are discussed.     

Communal Responsiveness in Relationships with Female versus Male Family Members

Two studies of college students in the US utilized a new methodological approach in which participants arranged their multiple family members (i.e. parents, siblings, aunts, and uncles) within a series of relationship network grids. These grids measured participants’ own feelings of communal responsiveness toward and perceived feelings of communal responsiveness from each family member relative to one another. The results of Study 1 (N = 86) and Study 2 (N = 111) supported the hypotheses that (1) people perceive more responsiveness from female family members than from male family members and (2) people feel more responsive toward female than toward male family members. Study 2 provided evidence that these associations were mediated by felt and perceived intimacy, dependence, and obligation, but not liking.     

Blaming a Few Bad Apples to Save a Threatened Barrel: The System‐Justifying Function of Conspiracy Theories

This research demonstrates that conspiracy theories—often represented as subversive alternatives to establishment narratives—may bolster, rather than undermine, support for the social status quo when its legitimacy is under threat. A pilot study (N = 98) found a positive relationship between conspiracy belief and satisfaction with the status quo. In Study 1 (N = 120), threatening (vs. affirming) the status quo in British society caused participants to endorse conspiracy theories. In Study 2 (N = 159), exposure to conspiracy theories increased satisfaction with the British social system after this had been experimentally threatened. In Study 3 (N = 109), this effect was mediated by the tendency for participants exposed (vs. not exposed) to conspiracy theories to attribute societal problems relatively more strongly to small groups of people rather than systemic causes. By blaming tragedies, disasters, and social problems on the actions of a malign few, conspiracy theories can divert attention from the inherent limitations of social systems.     

Effects of Ingroup Bias and Gender Role Violations on Acquaintance Rape Attributions

Two studies of ethnically diverse US college students from northern California examined whether ingroup bias and gender norm violations influence acquaintance rape attributions (Study 1, N?=?118; Study 2, N?=?140). Participants read vignettes depicting acquaintance rape and completed questionnaires. Victims were part of participants’ ingroup or outgroup. Study 1 manipulated the victim’s sexual history (chaste or promiscuous). Study 2 manipulated the victim’s alcohol use (sober or intoxicated). Ingroup victims were perceived more positively than outgroup victims if the victims were promiscuous or intoxicated. More guilt was attributed to rapists of ingroup victims than outgroup victims if the victims were promiscuous or intoxicated. Findings are examined in relation to ingroup bias and gender norm violations.     

The impact of meaning and dimensionality on the accuracy of children's copying

Studies of intellectual realism have shown that children aged 7 to 9 copy a line drawing of a cube less accurately than a non‐object pattern composed of the same lines ( Phillips, Hobbs, & Pratt, 1978 ). However, it remains unclear whether performance is worse on the cube because it is a three‐dimensional representation, or because it is a meaningful object, or both. The accuracy with which twenty 7‐year‐old and twenty 9‐year‐old children reproduced 16 line drawings of two‐dimensional and three‐dimensional objects and non‐objects was assessed. Older children copied all types of drawing more accurately than younger participants, and children of all ages copied two‐dimensional drawings more accurately than three‐dimensional. Meaningfulness interacted with dimensionality for ratings of drawing accuracy, assisting the copying of two‐dimensional drawings, but having no impact on the copying of three‐dimensional drawings. For an objective measure based on position, length, and orientation of line, meaningfulness interacted with age group, being beneficial for 7‐ but not 9‐year‐olds. Overall, the results imply that, contrary to previous suggestions, meaningfulness can actually be beneficial to copying.     

Drawing what lies ahead: False intentions are more abstractly depicted than true intentions

The aim of this study was to examine how people mentally represent and depict true and false statements about claimed future actions—so‐called true and false intentions. On the basis of construal level theory, which proposes that subjectively unlikely events are more abstractly represented than likely ones, we hypothesized that false intentions should be represented at a more abstract level than true intentions. Fifty‐six hand drawings, produced by participants to describe mental images accompanying either true or false intentions, were rated on level of abstractness by a second set of participants (N = 117) blind to the veracity of the intentions. As predicted, drawings of false intentions were rated as more abstract than drawings of true intentions. This result advances the use of drawing‐based deception detection techniques to the field of true and false intentions and highlights the potential for abstractness as a novel cue to deceit.     

Embodied metaphor and the “true” self: Priming entity expansion and protection influences intrinsic self-expressions in self-perceptions and interpersonal behavior

Drawing on conceptual metaphor perspectives and embodied cognition theories, we proposed that the intrinsic self-concept-who people think they truly are-is represented metaphorically as a physical entity, and that expressions of the intrinsic self-concept are therefore conceptualized in terms of entity activity. Using an empirical strategy for experimentally investigating conceptual metaphor, we tested whether exposure to pictorial primes depicting entity expansion and protection produces metaphor-consistent effects on self-perceptions and interpersonal behaviors expressive of the intrinsic self-concept. In Study 1, participants primed with entity expansion perceived themselves as more self-actualized and less concerned with satisfying extrinsic contingencies of self-esteem. Study 2 showed that this effect was mediated by the increased accessibility of the concept entity expansion. In Study 3, expansion-primed participants conformed less to other people's opinions. In Study 4, participants primed with entity protection were less willing to disclose intimate, but not non-intimate, self-knowledge to a stranger.     

Rising up to higher virtues: Experiencing elevated physical height uplifts prosocial actions

Many challenges of society involve getting people to act prosocially in ways that are costly for self-interests but beneficial to the greater good. The authors in four studies examined the novel hypothesis that elevating (vertical) height promotes prosocial actions. In Study 1, shoppers riding up (vs. down) escalators contributed more often to charity. In Study 2, participants sitting higher (vs. lower) helped another longer, while in Study 3 participants sitting higher (vs. lower) were more compassionate. In Study 4, watching video primes depicting scenes from a high perspective led to more cooperative resource conservation. These studies contribute uniquely to the prosociality literature by documenting previously unexamined effects of metaphor-enriched social cognition, and to the metaphor-enriched social cognition literature by documenting effects of elevated height on real prosocial actions.
