Epistemic vigilance online: Textual inaccuracy and children's selective trust in webpages.

In this age of 'fake news', it is crucial that children are equipped with the skills to identify unreliable information online. Our study is the first to examine whether children are influenced by the presence of inaccuracies contained in webpages when deciding which sources to trust. Forty-eight 8- to 10-year-olds viewed three pairs of webpages, relating to the same topics, where one webpage per pair contained three obvious inaccuracies (factual, typographical, or exaggerations, according to condition).

Does the majority always know best? Young children's flexible trust in majority opinion.

Copying the majority is generally an adaptive social learning strategy but the majority does not always know best. Previous work has demonstrated young children's selective uptake of information from a consensus over a lone dissenter. The current study examined children's flexibility in following the majority: do they overextend their reliance on this heuristic to situations where the dissenting individual has privileged knowledge and should be trusted instead? Four- to six- year-olds (N = 103) heard conflicting claims about the identity of hidden drawings from a majority and a dissenter in two between-subject conditions: in one, the dissenter had privileged knowledge over the majority (he drew the pictures); in the other he did not (they were drawn by an absent third party).

Children's trust in unexpected oral versus printed suggestions: limitations of the power of print.

Children have a bias to trust spoken testimony, yet early readers have an even stronger bias to trust print. Here, we ask how enduring is the influence of printed testimony: Can the learning be applied to new scenarios? Using hybrid pictures more dominant in one animal species (e.g.

To the letter: early readers trust print-based over oral instructions to guide their actions.

Children have many opportunities to learn from others through oral and written sources. Recent evidence suggests that early readers place more trust in written over oral testimony when learning names for unfamiliar objects. Across three studies, we examined whether the authority of print extends beyond mere naming to guide children's actions in the physical world.

The power of print: children's trust in unexpected printed suggestions.

How do children evaluate the veracity of printed text? We examined children's handling of unexpected suggestions conveyed via print versus orally. In Experiment 1 (N=131), 3- to 6-year-olds witnessed a speaker either read aloud an unexpected but not completely implausible printed label (e.g.

Take it as read: origins of trust in knowledge gained from print.

The ability to read opens up the possibility of learning about the world indirectly via print sources, providing a powerful new opportunity for children who have for years learned effectively from what people tell them. We compared children's trust in printed versus oral information. We also examined whether children who showed preferential trust in an informant with print assumed that the informant was still reliable about new information offered without print support.

Reading to learn: prereaders' and early readers' trust in text as a source of knowledge.

Literacy gives children an opportunity to benefit from others' knowledge and experience that far exceeds what they can achieve when reliant on learning orally via personal encounters. Little is known about young children's understanding and use of print as a source of knowledge. Three experiments investigated children's use and understanding of printed names as sources of information about the identity of unfamiliar targets.

Best friends: children use mutual gaze to identify friendships in others.

This study examined children's ability to use mutual eye gaze as a cue to friendships in others. In Experiment 1, following a discussion about friendship, 4-, 5-, and 6-year-olds were shown animations in which three cartoon children looked at one another, and were told that one target character had a best friend. Although all age groups accurately detected the mutual gaze between the target and another character, only 5- and 6-year-olds used this cue to infer friendship.

When being right is not enough: four-year-olds distinguish knowledgeable informants from merely accurate informants.

Recent evidence demonstrates that children are selective in their social learning, preferring to learn from a previously accurate speaker than from a previously inaccurate one. We examined whether children assessing speakers' reliability take into account how speakers achieved their prior accuracy. In Study 1, when faced with two accurate informants, 4- and 5-year-olds (but not 3-year-olds) were more likely to seek novel information from an informant who had previously given the answers unaided than from an informant who had always relied on help from a third party.

Eye-movement patterns are associated with communicative competence in autistic spectrum disorders.

Background: Investigations using eye-tracking have reported reduced fixations to salient social cues such as eyes when participants with autism spectrum disorders (ASD) view social scenes. However, these studies have not distinguished different cognitive phenotypes.

Methods: The eye-movements of 28 teenagers with ASD and 18 typically developing peers were recorded as they watched videos of peers interacting in familiar situations.

Tell-tale eyes: children's attribution of gaze aversion as a lying cue.

This study examined whether the well-documented adult tendency to perceive gaze aversion as a lying cue is also evident in children. In Experiment 1, 6-year-olds, 9-year-olds, and adults were shown video vignettes of speakers who either maintained or avoided eye contact while answering an interviewer's questions. Participants evaluated whether the speaker was telling the truth or lying on each trial.

Do individuals with autism process words in context? Evidence from language-mediated eye-movements.

It is widely argued that people with autism have difficulty processing ambiguous linguistic information in context. To investigate this claim, we recorded the eye-movements of 24 adolescents with autism spectrum disorder and 24 language-matched peers as they monitored spoken sentences for words corresponding to objects on a computer display. Following a target word, participants looked more at a competitor object sharing the same onset than at phonologically unrelated objects.

Children's use of the temporal dimension of gaze for inferring preference.

This study examined 4- and 5-year-olds' ability to spontaneously use the relative duration and frequency of another's object-directed gaze for inferring that person's preference. In Experiment 1, analysis revealed a strong age effect for judgment accuracy, which could not be accounted for by cue-monitoring proficiency. Reducing the saliency of the objects in Experiment 2 yielded significant improvement in the younger children's performance.
