ABSTRACT
Research has shown that adults' recognition of a facial part can be disrupted if the part is learnt without a face context but tested in a whole face. This has been interpreted as the holistic interference effect. The present study investigated whether children of 6- and 9-10-year-olds would show a similar effect. Participants were asked to judge whether a probe part was the same as or different from a test part whereby the part was presented either in isolation or in a whole face. The results showed that while all the groups were susceptible to a holistic interference, the youngest group was most severely affected. Contrary to the view that piecemeal processing precedes holistic processing in the cognitive development, our findings demonstrate that holistic processing is already present at 6 years of age. It is the ability to inhibit the influence of holistic information on piecemeal processing that seems to require a longer period of development into at an older and adult age.

Mentions: For A′, results of the analysis showed effects of condition F(3,345) = 17.68, p<.001 and group F(2,115) = 13.26, p<.001. However, these results were qualified by the two-way interaction F(6,345) = 5.41, p<.001 (see Figure 2). We conducted a separate simple main effects analysis for each condition, which revealed that the interaction was due to a lack of group difference in the part-part condition F(2,115) = 2.52, p>.05, but clear differences in the other conditions. In the part-whole condition F(2,115) = 5.27, p<.01, the adults performed better than the 6-year-olds. In the whole-part condition F(2,115) = 5.64, p>.01, the 9–10-year-olds and adults performed better than the 6-year-olds, with no difference between the two older groups (p>.05). The same pattern of findings was found in the whole-whole condition F(2,115) = 11.79, p<.001, with the two older groups performing better than the 6-year-olds. These results indicate that group differences emerged only when a whole face was presented, either once or twice, with the 9–10-year-olds and adults performing better than the 6-year-olds under these conditions.
