Experiment 1 tested 7-month-olds' performance in a global-level task, contrasting animals and vehicles in three conditions: (1) with basic-level labels (i.e. "car"), (2) with global-level labels (i.e. "vehicle"), and (3) with no labelling. Experiment 2 tested 11-month-olds' performance using the same task and the same conditions. Finally, Experiment 3 tested 11 month-olds' performance in a basic-level task, contrasting cars and trucks in two conditions: (1) with basic-level labels (i.e. "car", "truck"), and (2) with no labelling. Findings suggest that although performance of 7-month-olds? improved by the presence of object labels, the kind of labels used did not influence their categorization ability (Experiment 1). At 11 months, the impact of labels varied with the level of contrast presented: In a global-level task (Experiment 2), labels increased the general level of attention to the exemplars but the kind of labelling did not have any impact on categorization results. In a basic-level task (Experiment 3), categorization performance varied systematically with the presence of language input: Only infants participating in the labelling condition successfully accomplished the task and discriminated the basic-level categories. Since it is well known that a global-to-basic level shift exists in preverbal categorization between 7- to-11 months of age, these findings suggest that infants profit most from labeling when they are about to learn a given category. Once the category is formed, labelling seems to increase general attention to exemplars within that category but do not change the pattern of responding.
