“…Other work in visual memory that does not involve occlusion events suggests that infants have substantial long term memory for events. Rovee-Collier and colleagues (for review, see Hartshorn & Rovee-Collier, 1997;Hartshorn et al, 1998;Hitchcock & Rovee-Collier, 1996) used operant conditioning to access 2-to 6-month-old infants' ability to associate their own kicking with the motions of a mobile. The results of these studies showed that from 2 month of age infants could show retention for the task for 1 day and 6-month-olds could show retention for 14 days.…”

We examined 6-month-olds abilities to represent occluded objects, using a corneal-reflection eye-tracking technique. Experiment 1 compared infants' ability to extrapolate the current pre-occlusion trajectory with their ability to base predictions on recent experiences of novel object motions. In the first condition infants performed at asymptote ($2/3 accurate predictions) from the first occlusion passage. In the second condition all infants initially failed to make accurate prediction. Performance, however, reached asymptote after two occlusion passages. This is the first study that demonstrates such rapid learning effects during an occlusion task. Experiment 2 replicates these effects and demonstrates a robust memory effect extending 24 h. In occlusion tasks such long-term memory effects have previously only been observed in

“…In addition, the ability to recall an event from a related ' prime' or associated contingency or cue increases as a function not only of age, but also of the duration of the prime (Hsu, Rovee-Collier, Hill, Grodkiewicz & Joh, 2005): Hsu et al (2005) found that the duration of a prime needed to reactivate a memory decreased logarithmically with age. Additionally, changes in the cue or context used to elicit a memory (for example, in the kicking paradigm, the color of the mobile or the size of the room) affect memory less and less dramatically from 2 to 12 months of age (Hartshorn et al, 1998b). These developmental patterns in memory could help explain the contrasting results of the segmentation experiments that we are concerned with here.…”

Article:DePaolis, R.A., Vihman, Marilyn orcid.org/0000-0001-8912-4840 and Keren-Portnoy, Tamar orcid.org/0000-0002- 7258-2404 (2014) Previous studies have shown that by 11 but not by 10 months infants recognize words that have become familiar from everyday life independently of the experimental setting. This study explored the ability of 10-, 11-, and 12-month-old infants to recognize familiar words in sentential context, without experimental training. The headturn preference procedure was used to contrast passages containing words likely to be familiar to the infants with passages containing words unlikely to have been previously heard. Two stimulus words were inserted near the beginning and end of each of a set of simple sentence frames. The ability to recognize the familiar words within sentences emerged only at 12 months of age. The contrast between segmentation abilities as they emerge as a result of everyday exposure to language, as assessed here, and those abilities as measured in studies in which words are experimentally trained is discussed in terms of memory-based mechanisms.
