Helping and Cooperation at 14 Months of AgeInfancy - Tập 11 Số 3 - Trang 271-294 - 2007
Felix Warneken, Michael Tomasello
Two experiments investigated the proclivity of 14‐month‐old infants (a) to altruistically help others toward individual goals, and (b) to cooperate toward a shared goal. The infants helped another person by handing over objects the other person was unsuccessfully reaching for, but did not help reliably in situations involving more complex goals. When a programmed adult partner interrupted ...... hiện toàn bộ

Rushen Shi, Andréane Melançon
Recent work showed that infants recognize and store function words starting from the age of 6–8 months. Using a visual fixation procedure, the present study tested whether French‐learning 14‐month‐olds have the knowledge of syntactic categories of determiners and pronouns, respectively, and whether they can use these function words for categorizing novel words to nouns and verbs. The proso...... hiện toàn bộ

12‐Month‐Olds Produce Others' Intended but Unfulfilled ActsInfancy - Tập 14 Số 3 - Trang 377-389 - 2009
Mark Nielsen
Following Meltzoff's (1995) behavioral reenactment paradigm, this study investigated the ability of 12‐month‐olds (N = 44) to reproduce a model's attempted‐but‐failed actions on objects. Testing was conducted using a novel set of objects designed to enable young infants to readily identify the potential outcome of the model's actions. Infants who saw an adult's a...... hiện toàn bộ
