Gergely, Bekkering, and Kiraly (2002) demonstrated that 14-month-old infants engage in "rational imitation." To investigate the development and flexibility of this skill, we tested 12-month-olds on a different but analogous task. Infants watched as an adult made a toy animal use a particular action to get to an endpoint. In 1 condition there was a barrier that prevented a more straightforward action and so gave the actor no choice but to use the demonstrated action. In the other condition there…

The Development of Rational Imitation in 9- and 12-Month-Old Infants.

Findings clarify the onset of rational imitation by showing that 12-month-olds (but not 9- month-olds) take into account a situational constraint only when the constraint is nonvoluntary and explicit.

Rational tool use and tool choice in human infants and great apes.

In each of the current 3 studies, a comparison group of 14-month-olds used a tool more often when a demonstrator freely chose to use the tool than when she had to use it, but apes generally used the tool equally often in both conditions (orangutans were an exception).

Infants' Rational Imitation: Does the Model's Reliability Matter?

The current study examined whether the reliability of an individual's gaze influences infants' decision to imitate her novel actions. Infants were first administered an object search task wherein

12-Month-Olds Produce Others' Intended but Unfulfilled Acts.

It is shown that, contrary to previous studies, 12-month-olds can produce the intended but unconsummated acts of others.

Enculturated chimpanzees imitate rationally.

Like human infants, chimpanzees imitated the modeled action more often in the hands Free than in the Hands Occupied condition, suggesting that enculturated chimpanzees have some understanding of the rationality of others' intentional actions, and use this understanding when imitating others.

Fourteen-Month-Olds Adapt Their Imitative Behavior in Light of a Model’s Constraints

Rather than reenacting every action they observe, preverbal infants adapt their imitative behavior. Although previous studies have revealed the capability of preverbal infants to imitate selectively,

Twelve- and 18-month-olds copy actions in terms of goals.

In the context of an imitation game, 12- and 18-month-old infants saw an adult do such things as make a toy mouse hop across a mat (with sound effects). In one condition (House), the adult ended by

Taking the intentional stance at 12 months of age

Unwilling versus unable: infants' understanding of intentional action.

Findings provide especially rich evidence that infants first begin to understand goal-directed action at around 9 months of age, as opposed to six-month-olds, who showed no evidence of this differentiation.

Twelve-Month-Old Infants Interpret Action in Context

It is indicated that 12-month-old infants relate single actions to overarching goals and that they do so by construing goal-directed action in a causal framework.

Understanding attention: 12- and 18-month-olds know what is new for other persons.

Infants at 12 and 18 months of age played with 2 adults and 2 new toys, and lent support to the hypothesis that 1-year-old infants possess a genuine understanding of other persons as intentional and attentional agents.

Infants Determine Others' Focus of Attention by Pragmatics and Exclusion

In the studies presented here, infants' understanding of others' attention was assessed when gaze direction cues were not diagnostic. Fourteen-, 18- and 24-month-olds witnessed an adult look to the

Developmental psychology: Rational imitation in preverbal infants

The results indicate that imitation of goal-directed action by preverbal infants is a selective, interpretative process, rather than a simple re-enactment of the means used by a demonstrator, as was previously thought.
