Note. Keynames indicate whether a familiarization (f) or a habituation procedure (h) was used; what level was targeted (word, vowel, cons[onant], phrase); and which lab data were collected in. When the same experiment was presented to infants of different ages, this is coded in the keyname with a number (i.e., word1, word2, word3). Houston et al. (2007) used a habituation procedure on words. Age mean (SD) in months. Preference quotient or each day (PQ1, PQ2) with its SD as well as t against no preference, separately for each day (1, 2). r = correlation across days.
