More than language is needed to represent and combine different core knowledge components.

We question Spelke's key claim that the medium, in which contents from different core knowledge systems can be represented and combined, is language-based. Recalling an episodic memory, playing chess, and conducting mental rotation are tasks where core knowledge information is represented and combined. Although these tasks can be by means of language, these tasks are not inherently language-based.

6-, 10-, and 12-month-olds remember complex dynamic events across 2 weeks.

Whereas infants' ability to remember simple static material (e.g., pictures) has been documented extensively, we know surprisingly little about infants' memory of dynamic events (i.

To ask or not to ask: strategic recall, but not spontaneous recall, decreases by the passage of time in 46-month-olds' memory of a unique event.

Children's ability to intentionally recall events lessens with temporal distance to the occurrence. However, little is known about the effects of retention time on memories that emerge spontaneously. We examined spontaneous and strategic retrieval in eighty-one 46-month-olds' memory of a lab event after 1 week (the 1-week Condition) versus 43 weeks (the 43-week Condition) in a between-subjects design, using well-established procedures (Krøjgaard et al.

On the importance of contextual cues for spontaneous recall in 35- and 46-month-old children.

Recent evidence shows that returning to the same distinct lab setting after 1 week triggers spontaneous memories in 35- and 46-month-old children. However, it remains unclarified which specific cues are triggering spontaneous recall. We report two experiments in which distinct contextual cues were altered between encoding and test.

Predicting explicit memory for meaningful cartoons from visual paired comparison in infants and toddlers.

We tested the memory of 18-, 33-, and 39-month-olds (N = 120) for dynamic stimulus material (simple cartoons) after 6 months in a visual paired comparison (VPC) task. We also tested the explicit recognition memory (ERM) for the same material. Only the oldest age group (39-month-olds) showed a significant visual (familiarity) preference at the test.

Noting a difference: change in social context prompts spontaneous recall in 46-month-olds, but not in 35-month-olds.

An experimental paradigm has shown that it is possible to activate spontaneous memories in children by having them re-visit the setting in which they were introduced to a memorable event. Nevertheless, the most important cues for spontaneous recall remain undetermined. In response, we investigated the importance of the experimenter by introducing 35-month-olds (n = 62) and 46-month-olds (n = 62) to the same or a new person after one week.

Eight-year-olds, but not six-year-olds, perform just as well as adults when playing Concentration: Resolving the enigma?

Anecdotal reports suggest that children often outperform adults when playing Concentration. This is surprising as cognitive processes tend to develop progressively throughout childhood. To date, very few studies have examined this apparent paradox, and with mixed results.

Meaningful Memory? Eighteen-Month-Olds Only Remember Cartoons With a Meaningful Storyline.

In two studies we investigated the importance of a storyline for remembering cartoons across a delay of 2 weeks in 18-month-old infants by means of the visual paired-comparison (VPC) paradigm. In Study 1 seventy-one 18-month-olds were tested using similar cartoons as in a recent study from our lab while varying the richness of the storyline information. In a VPC task half of the infants watched uncompromised versions of the cartoons used in the recent study (Storyline Condition), whereas the other half watched Pixelized versions of the cartoons (number of pixels reduced by 98% covering up the narrative, but leaving perceptual details, e.

Thirty-five-month-old children have spontaneous memories despite change of context for retrieval.

Many parents have experienced incidents in which their preschool child spontaneously (i.e., without prompting of any kind) recall a previously experienced event.

Bound to remember: Infants show superior memory for objects presented at event boundaries.

Following Event Segmentation Theory (EST) adult memory is enhanced at event boundaries (EB). The present study set out to explore this in infancy. Sixty-eight 21-month-olds watched a cartoon with one of two objects (counterbalanced) inserted for 3s either at EB or between EB.

Visual attention to meaningful stimuli by 1- to 3-year olds: implications for the measurement of memory.

The visual recognition memory (VRM) paradigm has been widely used to measure memory during infancy and early childhood; it has also been used to study memory in human and nonhuman adults. Typically, participants are familiarized with stimuli that have no special significance to them. Under these conditions, greater attention to the novel stimulus during the test (i.

Occlusions at event boundaries during encoding have a negative effect on infant memory.

The present study investigated the importance of Event Boundaries for 16- and 20-month-olds' (n=80) memory for cartoons. The infants watched one out of two cartoons with ellipses inserted covering the screen for 3s either at Event Boundaries or at Non-Boundaries. After a two-week delay both cartoons (one familiar and one novel) were presented simultaneously without ellipses while eye-tracking the infants.

Where There's Smoke, There's Fire: the Effect of Truncated Testimony on Juror Decision-making.

In countries that allow child complainants of abuse to present their direct evidence via pre-recorded videotape, the recording is sometimes truncated for relevance or admissibility purposes before it is presented to the jury. In two experiments, we investigated how this practice affects mock jurors' judgments of child credibility and defendant culpability when truncation omitted the child's less plausible allegations. Mock jurors read a transcript of a 6-year-old girl making an abuse allegation against the janitor at her school.
