a
Response patterns based on ordered pairs depicting the two infant behaviors in the order: tongue protrusions, mouth openings.
+ = a matching response, − = a mismatching response, 0 = an equal response to both displays. Each row in the table adds to 16, because there were 16 subjects in the experiment.
