Table 2.
Means (standard deviations) of looking time (Experiment 1) or run time (Experiments 2 and 3) for each experiment by age. “Pre” is the average across the first three trials of the habituation phase, “baseline” is the average across the last three trials of the habituation phase. “Same” and “different” are means for the test trials, separately for each habituation group. “NT” is number of participants in the triumph group, “NR” is the number of participants in the relief group.
