The Role of Speaker Knowledge in Children's Pragmatic Inferences

During communication, conversational partners should offer as much information as is required and relevant. For instance, the statement “Some Xs Y” is infelicitous if one knows that all Xs Y. Do children understand the link between speaker knowledge and utterance strength? In Experiment 1, 5‐year‐olds (N = 32) but not 4‐year‐olds (N = 32) reliably connected statements of different logical strength (e.g., “The girl colored all/some of the star”) to observers who were fully or partially informed. Four‐year‐olds’ performance improved when observer knowledge could be assessed more easily (Experiment 2a, N = 25) but remained the same in a nonlinguistic version of Experiment 1 that preserved the epistemic requirements of the original study (Experiment 2b, N = 26). These findings have implications for the development of early communicative abilities.     

Explaining Constrains Causal Learning in Childhood

Three experiments investigate how self‐generated explanation influences children's causal learning. Five‐year‐olds (N = 114) observed data consistent with two hypotheses and were prompted to explain or to report each observation. In Study 1, when making novel generalizations, explainers were more likely to favor the hypothesis that accounted for more observations. In Study 2, explainers favored a hypothesis that was consistent with prior knowledge. Study 3 pitted a hypothesis that accounted for more observations against a hypothesis consistent with prior knowledge. Explainers were more likely to base generalizations on prior knowledge. Findings suggest that attempts to explain drive children to evaluate hypotheses using features of “good” explanations, or those supporting generalizations with broad scope, as informed by children's prior knowledge and observations.     

Infants Rely More on Gaze Cues From Own‐Race Than Other‐Race Adults for Learning Under Uncertainty

Differential experience leads infants to have perceptual processing advantages for own‐ over other‐race faces, but whether this experience has downstream consequences is unknown. Three experiments examined whether 7‐month‐olds (range = 5.9–8.5 months; N = 96) use gaze from own‐ versus other‐race adults to anticipate events. When gaze predicted an event's occurrence with 100% reliability, 7‐month‐olds followed both adults equally; with 25% (chance) reliability, neither was followed. However, with 50% (uncertain) reliability, infants followed own‐ over other‐race gaze. Differential face race experience may thus affect how infants use social cues from own‐ versus other‐race adults for learning. Such findings suggest that infants integrate online statistical reliability information with prior knowledge of own versus other race to guide social interaction and learning.     

Prelinguistic Relational Concepts: Investigating Analogical Processing in Infants

This research asks whether analogical processing ability is present in human infants, using the simplest and most basic relation—the same–different relation. Experiment 1 (N = 26) tested whether 7‐ and 9‐month‐olds spontaneously detect and generalize these relations from a single example, as previous research has suggested. The attempted replication failed. Experiment 2 asked whether infants could abstract the relation via analogical processing (Experiment 2, N = 64). Indeed, with four exemplars, 7‐ and 9‐month‐olds could abstract the same–different relation and generalize it to novel pairs. Furthermore, prior experience with the objects disrupted learning. Facilitation from multiple exemplars and disruption by individual object salience are signatures of analogical learning. These results indicate that analogical ability is present by 7 months.     

Taking Shape: Supporting Preschoolers' Acquisition of Geometric Knowledge Through Guided Play

Shape knowledge, a key aspect of school readiness, is part of early mathematical learning. Variations in how children are exposed to shapes may affect the pace of their learning and the nature of their shape knowledge. Building on evidence suggesting that child‐centered, playful learning programs facilitate learning more than other methods, 4‐ to 5‐year‐old children (N = 70) were taught the properties of four geometric shapes using guided play, free play, or didactic instruction. Results revealed that children taught shapes in the guided play condition showed improved shape knowledge compared to the other groups, an effect that was still evident after 1 week. Findings suggest that scaffolding techniques that heighten engagement, direct exploration, and facilitate “sense‐making,” such as guided play, undergird shape learning.     

Measuring Beliefs in Centimeters: Private Knowledge Biases Preschoolers' and Adults' Representation of Others' Beliefs

A novel task, using a continuous spatial layout, was created to investigate the degree to which (in centimeters) 3‐year‐old children's (N = 63), 5‐year‐old children's (N = 60), and adults' (N = 60) own privileged knowledge of the location of an object biased their representation of a protagonist's false belief about the object's location. At all ages, participants' knowledge of the object's actual location biased their search estimates, independent of the attentional or memory demands of the task. Children's degree of bias correlated with their performance on a classic change‐of‐location false belief task, controlling for age. This task is a novel tool for providing a quantitative measurement of the degree to which self‐knowledge can bias estimates of others' beliefs.     

How individual interest influences situational interest and how both are related to knowledge acquisition: A microanalytical investigation

The extent to which a student experiences situational interest during a learning task is dependent on at least two factors: (1) external stimuli in the learning environment that arouse interest and (2) internal dispositions, such as individual interest. The objective of the present study was to disentangle how both factors influence situational interest during task engagement. Two data sets were collected from primary school science (N = 186) and secondary school history students (N = 71). Path analysis was used to examine the influence of individual interest on seven situational interest measurements and knowledge acquisition. The results suggest that individual interest has only a significant influence on situational interest at the beginning of a task and then its influence fades. In addition, individual interest is not a significant predictor of learning. Only situational interest predicts knowledge acquisition. Implications of these findings for interest research are discussed.     

Challenging the knowledge‐transfer orthodoxy: Knowledge co‐construction in technology‐enhanced learning for children with autism

Experimental intervention studies constitute the current dominant research designs in the autism education field. Such designs are based on a ‘knowledge‐transfer’ model of evidence‐based practice in which research is conducted by researchers, and is then ‘transferred’ to practitioners to enable them to implement evidence‐based interventions. While these research designs contribute important knowledge, they lead to a gap between what the research evidence may prescribe and what happens in practice, with a concomitant disparity between the priorities of researchers and practitioners. This paper discusses findings from the ESRC‐funded ‘SHAPE’ project, which adopted a different model of evidence‐based practice, focusing on knowledge co‐construction. Pupils (N = 8), teachers (N = 10), a speech and language therapist and a parent in three different school communities investigated creative ways in which children's social communication skills could be enhanced through technology use. Through a participatory methodology, digital stories were used as a method to enable engagement with the practical realities of the classroom and empower practitioners to construct and share their own authentic narratives. Participants articulated precise knowledge about the learning opportunities afforded to them and their pupils through quality interactions that were mediated by the technologies, as evidenced through digital stories. The SHAPE project shows that it is feasible to develop methodologies that enable genuine knowledge co‐construction with school practitioners, parents and pupils. Such co‐construction could offer realistic opportunities for pedagogical emancipation and innovation in evidence‐based practice as an alternative to the currently dominant and narrow model of knowledge transfer.     

Do Parents Foster Self‐Esteem? Testing the Prospective Impact of Parent Closeness on Adolescent Self‐Esteem

Close parent–child relationships are viewed as important for the development of global self‐esteem. Cross‐sectional research supports this hypothesis, but longitudinal studies provide inconsistent prospective effects. The current study uses data from Germany (N = 982) and the United States (N = 451) to test longitudinal relations between parent–child closeness and adolescent self‐esteem. The authors used self‐, parent‐, and observer‐reported parent–child closeness and self‐reported self‐esteem from ages 12 to 16. Results replicated concurrent correlations found in the literature, but six longitudinal models failed to show prospective relations. Thus, the longitudinal effect of parent–child closeness and self‐esteem is difficult to detect with adolescent samples. These findings suggest the need for additional theorizing about influences on adolescent self‐esteem development and longitudinal research with younger samples.     

Interest development: Arousing situational interest affects the growth trajectory of individual interest

Interest has become a central topic in the educational-psychology literature and Hidi and Renninger’s (2006) four-phase model of interest development is its most recent manifestation. However, this model presently enjoys only limited empirical support. To contribute to our understanding of how individual interest in a subject develops in learners, two studies were conducted with primary school science students. The first study (N = 187) tested the assumption that repeated arousal of situational interest affects the growth of individual interest. Latent growth curve modeling was applied and the results suggest that the arousal of situational interest has a positive effect on the development of individual interest and significantly influences its growth trajectory. The second study tested the assumption that engaging students with interest-provoking didactic stimuli, such as problems, is critical to triggering situational interest and increasing individual interest. To test this assumption, four classes of primary school students (N = 129) were randomly assigned to two conditions in a quasi-experimental setup. The treatment condition received four situational-interest-inducing science problems as part of a course whereas the control condition did not, all other things being equal. The results of latent growth curve modeling revealed that only the group receiving problems experienced repeated arousal of situational interest and its related growth in individual interest. Implications for, and amendments to, the four-phase model of interest development are proposed.     

I Don't Want to Pick! Introspection on Uncertainty Supports Early Strategic Behavior

Although some evidence indicates that even very young children engage in rudimentary forms of strategic behavior, the underlying mechanisms remain largely unknown. This study tested the hypothesis that uncertainty monitoring underlies such behaviors. Three‐, four‐, and five‐year‐old children (N = 88) completed a perceptual discrimination task. Results indicated that children are more likely to withhold (vs. volunteer) responses on trials for which, when forced to provide an answer, they report subjective uncertainty (vs. subjective certainty). Furthermore, uncertainty monitoring positively predicted the strategic regulation of accuracy via withholding of incorrect responses, even when controlling for individual differences in inhibitory control. Overall, results suggest that children's awareness of their own knowledge states contributes to early strategic behavior.     

The Self‐Reference Effect on Memory in Early Childhood

The self‐reference effect in memory is the advantage for information encoded about self, relative to other people. The early development of this effect was explored here using a concrete encoding paradigm. Trials comprised presentation of a self‐ or other‐image paired with a concrete object. In Study 1, 4‐ to 6‐year‐old children (N = 53) were asked in each trial whether the child pictured would like the object. Recognition memory showed an advantage for self‐paired objects. Study 2 (N = 55) replicated this finding in source memory. In Study 3 (N = 56), participants simply indicated object location. Again, recognition and source memory showed an advantage for self‐paired items. These findings are discussed with reference to mechanisms that ensure information of potential self‐relevance is reliably encoded.     

Self‐Socialization of Gender in African American,Dominican Immigrant,and Mexican Immigrant Toddlers

This article advances a self‐socialization perspective demonstrating that children's understanding of both gender categories represents an intergroup cognition that is foundational to the development of gender‐stereotyped play. Children's (N = 212) gender category knowledge was assessed at 24 months and play was observed at 24 and 36 months. Higher levels of gender category knowledge and, more specifically, passing multiple measures of knowledge of both gender categories at 24 months was related to increases in play over time with gender‐stereotyped toys (doll, truck), but not gender‐stereotyped forms of play (nurturing, motion). In contrast to the long‐standing focus on self‐labeling, findings indicate the importance of intergroup cognitions in self‐socialization processes and demonstrate the generalizability of these processes to a diverse sample.     

Words to Sleep On: Naps Facilitate Verb Generalization in Habitually and Nonhabitually Napping Preschoolers

A nap soon after encoding leads to better learning in infancy. However, whether napping plays the same role in preschoolers' learning is unclear. In Experiment 1 (N = 39), 3‐year‐old habitual and nonhabitual nappers learned novel verbs before a nap or a period of wakefulness and received a generalization test examining word extension to novel actors after 24 hr. Only habitual and nonhabitual nappers who napped after learning generalized 24 hr later. In Experiment 2 (N = 40), children learned the same verbs but were tested within 2–3 min of training. Here, habitual and nonhabitual nappers retained the mappings but did not generalize. The results suggest that naps consolidate weak learning that habitual and nonhabitual nappers would otherwise forget over periods of wakefulness.     

The Sexualized Girl: A Within‐Gender Stereotype Among Elementary School Children

Two studies (conducted in 2013) examined whether elementary‐aged children endorse a within‐gender stereotype about sexualized girls. In Study 1, children (N = 208) ages 6–11 rated sexualized girls as more popular but less intelligent, athletic, and nice compared to nonsexualized girls. These distinctions were stronger for girls and older children, and in accordance with our developmental intergroup theoretical framework, were related to children's cognitive development and media exposure. Study 2 (N = 155) replicated the previous findings using more ecologically valid and realistic images of girls and further explored individual differences in the endorsement of the sexualized girl stereotype. Additional results indicated that the belief that girls should be appearance focused predicted their endorsement of the sexualized girl stereotype.     

Children's Inferences About Friendship and Shared Preferences Based on Reported Information

Two experiments (total N = 195) examined third-party inferences about friendship and shared preferences from reported dyadic information. Four-year-olds (N = 48) inferred friendship between individuals based on reports of prosocial behavior, and similarity, but not based on arbitrary links. Children privileged prosocial behavior over similarity when asked to adjudicate between the two. Adults (N = 120) were tested online and showed the same overall pattern of inferences. Furthermore, 4-year-olds (N = 27) expected individuals who had engaged in prosocial behavior to be playmates as well as friends, and to share preferences for novel games, but not novel foods. These findings shed crucial light on preschoolers' third-party friendship inferences, and add to our knowledge of their concept of friendship.     

Modeling Prosocial Behavior Increases Helping in 16-Month-Olds

In two experiments, the imitation of helping behavior in 16-month-olds was investigated. In Study 1 (N = 31), infants either observed an adult model helping or not helping another individual before they had the opportunity to assist an unfamiliar experimenter. In one of two tasks, more children helped in the prosocial model condition than in the no model control condition. In Study 2 (N = 60), a second control condition was included to test whether infants imitated the prosocial intention (no neediness control). Children in the prosocial model condition helped more readily than children in the no model condition, with the second control condition falling in between. These findings propose that modeling provides a critical learning mechanism in early prosocial development.     

Increases in Cognitive and Linguistic Processing Primarily Account for Increases in Speaking Rate With Age

Age‐related increases of speaking rate are not fully understood, but have been attributed to gains in biologic factors and learned skills that support speech production. This study investigated developmental changes in speaking rate and articulatory kinematics of participants aged 4 (N = 7), 7 (N = 10), 10 (N = 9), 13 (N = 7), 16 (N = 9) years, and young adults (N = 11) in speaking tasks varying in task demands. Speaking rate increased with age, with decreases in pauses and articulator displacements but not increases in articulator movement speed. Movement speed did not appear to constrain the speaking. Rather, age‐related increases in speaking rate are due to gains in cognitive and linguistic processing and speech motor control.     

Relations Among Cultural Learning Beliefs,Self‐Regulated Learning,and Academic Achievement for Low‐Income Chinese American Adolescents

This mixed‐methods study of urban low‐income, English‐proficient Chinese American, second‐generation 15‐year‐olds (conducted in 2004; N = 32) examined the relation among the virtue model of learning communicated by parents and adolescents’ learning beliefs, self‐regulated learning (SRL) behaviors, and academic achievement. Analysis of in‐depth individual interviews revealed that for these adolescents, perceptions of family educational socialization predicted students’ endorsement of their culture's virtue‐oriented learning beliefs and that adolescents’ endorsement of these learning beliefs predicted their academic achievement. Importantly, adolescents’ reported that use of SRL strategies mediated the relationship between their endorsement of virtue‐oriented learning beliefs and their academic achievement. Findings are discussed in the context of further research linking cultural learning beliefs, SRL, and children's academic achievement.     

The Effect of Teachers' Memory‐Relevant Language on Children's Strategy Use and Knowledge

Building on longitudinal findings of linkages between aspects of teachers' language during instruction and children's use of mnemonic strategies, this investigation was designed to examine experimentally the impact of instruction on memory development. First and second graders (N = 54, M_age = 7 years) were randomly assigned to a science unit that varied only in teachers' use of memory‐relevant language. Pretest, posttest, and 1‐month follow‐up assessments revealed that although all participating children learned new information as a result of instruction, those exposed to memory rich teaching exhibited greater levels of strategic knowledge and engaged in more sophisticated strategy use in a memory task involving instructional content than did students exposed to low memory instruction. The findings provide support for a causal linkage between teachers' language and children's strategic efforts.
