Characterizing Children’s Expectations About Expertise and Incompetence: Halo or Pitchfork Effects?

Do children expect an expert in one domain to also be an expert in an unrelated domain? In Study 1, 32 three‐ and four‐year‐olds learned that one informant was an expert about dogs relative to another informant. When presented with pictures of new dogs or of artifacts, children who could remember which informant was the dog expert preferred her over the novice as an informant about the names of dogs, but they had no preference when the informants presented artifact labels. In Study 2, 32 children learned that one informant was incompetent about dogs whereas another was neutral. In this case, children preferred the neutral speaker over the incompetent one about both dogs and artifacts. Taken together, these results suggest that for children, expertise is not subject to a “halo effect,” but incompetence may be subject to a “pitchfork effect.”     

Beyond semantic accuracy: preschoolers evaluate a speaker's reasons

Children's sensitivity to the quality of epistemic reasons and their selective trust in the more reasonable of 2 informants was investigated in 2 experiments. Three-, 4-, and 5-year-old children (N = 90) were presented with speakers who stated different kinds of evidence for what they believed. Experiment 1 showed that children of all age groups appropriately judged looking, reliable testimony, and inference as better reasons for belief than pretense, guessing, and desiring. Experiment 2 showed that 3- and 4-year-old children preferred to seek and accept new information from a speaker who was previously judged to use the "best" way of thinking. The findings demonstrate that children distinguish certain good from bad reasons and prefer to learn from those who showcased good reasoning in the past.     

Children's Trust in Previously Inaccurate Informants Who Were Well or Poorly Informed: When Past Errors Can Be Excused

Past research demonstrates that children learn from a previously accurate speaker rather than from a previously inaccurate one. This study shows that children do not necessarily treat a previously inaccurate speaker as unreliable. Rather, they appropriately excuse past inaccuracy arising from the speaker's limited information access. Children ( N = 67) aged 3, 4, and 5 years aimed to identify a hidden toy in collaboration with a puppet as informant. When the puppet had previously been inaccurate despite having full information, children tended to ignore what they were told and guess for themselves: They treated the puppet as unreliable in the longer term. However, children more frequently believed a currently well-informed puppet whose past inaccuracies arose legitimately from inadequate information access.     

Preschoolers Continually Adjust Their Epistemic Trust Based on an Informant's Ongoing Accuracy

Children aged 4–7 years (N = 120) played four rounds of a find‐the‐sticker game. For each round, an informant looked into two cups and made a claim about which cup held a sticker. At the end of each round, children guessed the sticker's location, and then the sticker's actual location was revealed. For three of the rounds, the informant accurately reported the sticker's location. But critically, for one round—either Round 1, 2, or 3—she was inaccurate. Children continually adjusted their trust in the informant as they obtained more information about her accuracy. Relations between the informant's pattern of accuracy and children's trust were robust, neither mediated nor moderated by children inferences about her intent or traits.     

The influence of speaker reliability on first versus second label learning

Children's confidence in their own knowledge may influence their willingness to learn novel information from others. Twenty-four-month-old children's (N = 160) willingness to learn novel labels for either familiar or novel objects from an adult speaker was tested in 1 of 5 conditions: accurate, inaccurate, knowledgeable, ignorant, or uninformative. Children were willing to learn a second label for an object from a reliable informant in the accurate, knowledgeable, and uninformative conditions; children were less willing to apply a novel label to a familiar object if the speaker previously was inaccurate or had expressed ignorance. However, when the objects were novel, children were willing to learn the label regardless of the speaker's knowledge level.     

Limitations on reliability: regularity rules in the English plural and past tense

Two studies investigated 3- to 5-year-olds' trust in a reliable informant when judging novel labels and novel plural and past tense forms. In Study 1, children ( N = 24) endorsed the names of new objects given by an informant who had earlier labeled familiar objects correctly over the names given by an informant who had labeled the same objects incorrectly. In Study 2, children ( N = 24) endorsed novel names given by an informant who had earlier expressed the plural of familiar nouns correctly over one who had expressed the plural incorrectly. But children overwhelmingly endorsed the regular plural and past tense forms of new words provided by the formerly unreliable labeler (Study 1) or morphologist (Study 2) rather than irregular forms of those words provided by the formerly reliable informant.     

Children Trust a Consensus Composed of Outgroup Members—But Do Not Retain That Trust

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 for a consensus. Nevertheless, the initial strength and persistence of that preference depended on the racial composition of the consensus. Children's preference for consensus members belonging to the same race as themselves persisted even when only one consensus member remained to provide information. When the consensus consisted of different‐race informants, preference for the consensus was initially apparent but lost when only one member from the consensus remained with the dissenting informant.     

Extracting information from flowcharts and contingency statements: the effects of age and practice

Two studies are reported which aim to test the generality of the conclusions drawn from previous literature on the effectiveness of flowcharts with adult participants. In Experiment One secondary school children of different ages took part, and in Experiment Two a group of senior citizens participated. In both experiments, the effectiveness of a flow chart was compared with that of short contingency statements for finding a solution to a complex problem.
In Experiment One there was an initial advantage for the flow chart over the contingency statements in terms of speed but this was not the case in Experiment Two. Furthermore, the results showed there to be no significant differences in error rates between the two modes of presentation in both experiments. Participants who were particularly accurate responders did not respond any more slowly (or quickly) in Experiment One.
Practice at the task had marked effects. The differences in speed between the two modes of presentation on trial 1 were markedly reduced on trial 2 in both experiments and performance speeded up with practice. Age also played a part. In Experiment One, older children performed more rapidly than younger ones. In Experiment Two, the elderly participants found both formats very difficult to use. It seems that the generally accepted view that flowcharts are superior to contingency statements might not hold for younger participants or for the elderly, especially when accuracy is the main criterion.     

Early Childhood Education in Societal Context: Teachers in Three Countries Speak About Early Childhood Education

Building on the cross-cultural patterns and systems research as well as social constructivism, in-depth interviews were conducted with key informant early childhood teachers in three regions with similar characteristics in Sweden, Russia, and in the United States. Inductive analyses revealed differences in responses among Swedish, Russian and American informants related to the macro-, meso-, and micro-levels of societal system. United States teacher informants had a great number of separate topic comments and distributed them more evenly across all levels than did Russian and Swedish teacher informants who had more emphasis at the meso level. United States and Russian teacher informants discussed the lack of societal support for young children and their families, while Swedish teacher informants seemed to almost take this support for ranted. United States teacher informants suggested that early childhood programs were important in developing support networks among parents, while Russian teacher informants often gave information to parents and Swedish teachers spoke about mutually sharing information. United States teacher informants desired both strict rules with strong academic content and extension of the child's initiations through play; they emphasized activities and materials. Swedish teachers discussed a child- centered approach to social learning and creativity and desired to be with children rather than do activities with them. Russian teacher informants emphasized the importance of obedience, aesthetic education, and preparation for school and the labor of the larger society. These study outcomes deepen understanding about the multidemensional relationships between early childhood programs and societal contexts in which they are embedded, and they suggest alternative approaches to working with young children and their families.     

Effects of early and later family violence on children's behavior problems and depression: a longitudinal, multi-informant perspective

OBJECTIVES: To examine the effects of different forms of family violence at two developmental stages by assessing a sample of 110 Israeli children, drawn from the case files of Israeli family service agencies, studied longitudinally in both middle childhood and adolescence. METHODS: Information about the children's adjustment was obtained from parents, teachers, and the children themselves when the children averaged 10.6 and 15.9 years of age using the Child Behavior Checklist (CBCL), Teacher Report Form (TRF), Youth Self-Report (YSR), and Children's Depression Inventory (CDI). Information about the history of family violence was obtained from the mothers, fathers, children, and social workers. RESULTS: The results paint a mixed picture of the effects of family violence on children and adolescents. The relationship between concurrent behavior problems and abuse group varied by informant and study phase, although they were strongest when children were the informants. Predictions regarding the relationship between early abuse and later adjustment were only partially confirmed. Different informants did not agree about which groups of children were most adversely affected, there was little stability over time in the pattern of reported effects, and children were more likely than other informants to report levels of maladjustment that varied depending on recent or concurrent exposure to family violence. Many families changed their abuse status over time, and children who were new victims at follow-up had the most internalizing problems. Girls were found to be at more risk for internalizing and externalizing behavior problems than boys. CONCLUSIONS: Multiple informants are necessary to evaluate and assess the effects of family violence on children's behavior. Younger children may be more susceptible to the effects of family violence than older children, but problems manifest by some children may not carry over to adolescence. Changes in family and parenting practices, as well as in children's capacity to appraise and cope with family violence may help mitigate the adverse effects of family violence.     

Contrasting Social and Cognitive Accounts on Overimitation: The Role of Causal Transparency and Prior Experiences

Three experiments (N = 100) examine the influence of causal information on overimitation. In Experiment 1, a transparent reward location reveals that the reward is unaffected by nonfunctional actions. When 5‐year‐olds observe an inefficient and subsequently an efficient strategy to retrieve a reward, they show overimitation in both phases—even though the reward is visible. In Experiment 2, children observe first the efficient then the inefficient strategy. The latter is always demonstrated communicatively, whereas the efficient strategy is presented communicatively (2a) or noncommunicatively (2b). Regardless of whether the efficient strategy is emphasized through communication or not, most children do not switch from the efficient to the inefficient strategy. Depending on the situation, children base their behavior on social motivations or causal information.     

Elementary school-age children's capacity to choose positive diagnostic and negative diagnostic tests

Two experiments involving 72 elementary school-age children (mean age = 10 years, 3 months, range = 9,4-11,8) and 72 adults compared the ability of participants to choose positive and negative diagnostic tests over positive and negative nondiagnostic tests. Both experiments employed novel test materials, which resolved any issues regarding the effects of context on test strategy employment. In Experiment 1, both children and adults were significantly more likely to prefer positive diagnostic tests over positive nondiagnostic tests; however, only adults demonstrated a significant preference for negative diagnostic tests over positive nondiagnostic ones. In Experiment 2, both children and adults were more likely to choose negative diagnostic tests over negative nondiagnostic tests, demonstrating that despite a strong positive test bias, children could reason diagnostically in selecting among negative tests in cases in which only negative test choices were available.     

Informants' Traits Weigh Heavily in Young Children's Trust in Testimony and in Their Epistemic Inferences

This study examined how informants' traits affect how children seek information, trust testimony, and make inferences about informants' knowledge. Eighty‐one 3‐ to 6‐year‐olds and 26 adults completed tasks where they requested and endorsed information provided by one of two informants with conflicting traits (e.g., honesty vs. dishonesty). Participants also completed tasks where they simultaneously considered informants' traits and visual access to information when inferring their knowledge and trusting their testimony. Children and adults preferred to ask and endorse information provided by people who are nice, smart, and honest. Moreover, these traits influenced the knowledge that young children attributed to informants. Children younger than 5 years of age reported that people with positive traits were knowledgeable even when they lacked access to relevant information.     

INFORMANT EFFECTS ON BEHAVIORAL AND ACADEMIC ASSOCIATIONS: A LATENT VARIABLE LONGITUDINAL EXAMINATION

Discrepancies among informants’ ratings of a given child's behavior complicate the study of linkages between child behavior and academic achievement. In the current study, we examined the potential moderating effect of informant type on associations between behavior and two types of achievement in a longitudinal growth model that captured children's development from 54 months of age through fifth grade. Latent internalizing and externalizing behavioral constructs, as separately measured by mothers and teachers, were modeled as time‐varying predictors of achievements to capture changes that occur as children progress through different developmental stages. Behavioral ratings obtained by both informants explained largely equivalent levels of reading achievement variance, and teachers’ ratings of child behavior explained more variance in analytic type achievements than did those of mothers.     

Perception of kinetic illusory contours by two-month-old infants

Perception of kinetic illusory contours by 2-month-old infants was explored with sparse random-dot displays depicting an illusory shape against a background. In Experiment 1, 24 infants were habituated to a shape specified by accretion and deletion of background texture and relative motion, and exhibited a novelty preference when presented with luminance-defined familiar and novel shapes. Subsequent experiments explored kinetic cues in isolation. In Experiment 2 (n = 24), relative motion information was removed, leaving accretion and deletion of texture and luminance cues, and in Experiment 3 (n = 24), only relative motion information was available. In both these experiments the novelty preference obtained in Experiment 1 was replicated. Results from a control condition (n = 12) mitigated against the likelihood of an inherent preference for either of the test shapes. These findings reveal an early capacity to perceive shape solely from kinetic information, and suggest a mechanism geared toward spatiotemporal boundary formation that is functional shortly after birth. Theories of development of edge and motion discrimination are discussed.     

“Why Does Rain Fall?”: Children Prefer to Learn From an Informant Who Uses Noncircular Explanations

These two studies explored 3‐ and 5‐year‐olds' evaluation of noncircular and circular explanations, and their use of such explanations to determine informant credibility. Although 5‐year‐olds demonstrated a selective preference for noncircular over circular explanations (Experiment 1: Long Explanations; Experiment 2: Short Explanations), 3‐year‐olds only demonstrated a preference for the noncircular when the explanations were shortened (Experiment 2). Children's evaluation of the explanations extended to their inferences about the informants' future credibility. Both age groups demonstrated a selective preference for learning novel explanations from an informant who had previously provided noncircular explanations—although only 5‐year‐olds also preferred to learn novel labels from her. The implications and scope of children's ability to monitor the quality of an informant's explanation are discussed.     

Evaluating and Approaching a Strange Animal: Children's Trust in Informant Testimony

This study examined 3‐ to 7‐year‐old children's reliance on informant testimony to learn about a novel animal. Sixty participants were given positive or negative information about an Australian marsupial from an informant described as a maternal figure or a zookeeper. Children were asked which informant was correct and were invited to touch the animal, which was a stuffed toy hidden in a crate. Overall, younger children endorsed the zookeeper's testimony about the animal, but touched the animal more readily when the maternal figure provided positive information. Older children endorsed the informant who provided positive information, but showed some sensitivity to zookeeper expertise. Age differences were obtained in the association between participant characteristics and informant selection and animal approach behavior.     

Functional Measurement Assessment of Young Children''s Ability to Predict Future Behavior

The reported experiments demonstrate that young children's ability to use previous behavioral information to predict future behavior emerges on quantitative, but not dichotomous, judgment tasks. In a first experiment, kindergartners, second graders, and fourth graders made quantitative liking judgments and predictions for peers after being presented 2 pieces of behavioral information. Children of all 3 age groups used both pieces of information in their liking judgments and predictions. In a second experiment, kindergartners were presented with 2 types of tasks; one was a quantitative prediction, comparable to the task in Experiment 1, and the second were dichotomous predictions, comparable to judgment tasks typically used in other experiments. Children's predictions were significantly more consistent with the behavioral information on the quantitative task than on either of the dichotomous tasks. These results suggest that young children believe in the ability of interpersonal behavior, but have difficulty dealing with the complexity of some prediction tasks.     

Does the position of source information for multiple documents matter? Insights from two experiments

When processing information from multiple documents about a controversial topic, it is important to consider information about the respective documents’ sources. In two experiments, we investigated whether different ways of providing source information affects learners’ use of source information when trying to make sense of a controversy. Experiment 1 (123 participants) varied the position of source information before or after the contents as well as the integration of source information with the contents. When source information was integrated with contents, more participants tended to name the accurate answer when source information was presented before contents. However, for blocked (i.e. non-integrated) presentation, more participants gave an accurate answer when source information was presented after the contents. Experiment 2 (117 participants) tested whether this latter finding could be explained with a lack of conflict awareness when participants were confronted with all source information in a block before the contents. However, making learners aware of the conflicting nature of the documents before the learning phase did not change the pattern of results for the blocked presentation of source information. In contrast, highlighting the conflict just before learners answered the open-ended question resulted in more participants giving an accurate answer when source information was presented before rather than after the contents. These results are discussed taking into account the characteristics of the learning phase and the test phase, outlining various pathways for future research.
