Evidence of robust recognition memory early in life even when assessed by reaching behavior

Article Abstract:

Infants' recognition memory on a reaching task is equal to or better than that for a a looking task, even at 6 months of age. The subjects succeeded on a recognition memory task with delays as long as 10 minutes at a very early age, when they were reaching to gain the stimulus rather than something else. The study involved 120 infants aged 4 to twelve months, who were tested on either visual paired comparisons or delayed nonmatching to sample. The delayed nonmatching task was altered so that the stimulus itself was the reward.

What infant memory tells us about infantile amnesia: long-term recall and deferred imitation

Article Abstract:

The recollection of past events over long-term delays by infants indicates that they have a non-verbal declaratory memory system. Deferred imitation was significant for two experimental groups, and retention and imitation of multiple acts by infants was also found. A nonverbal method was used to assess long-term recall memory in a sample of 192 infants, aged 14 and 16 months. The findings have implications for the multiple memory system in cognitive science and neuroscience as well as for theories of infantile amnesia.

Blank comparison analysis of emergent symbolic mapping by young children

Article Abstract:

A blank-comparison test methodology has been used for the first time to study emergent symbolic mapping (ESM) by young typically developing children. The children almost consistently chose the undefined item on dictation of an undefined-sample word, even when the blank was present. This extends previous research where no blank was present. The use of blank-comparison shows promise in ESM learning research in young children.
