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: Stimuli were created from 80 greyscale images of White British children composed of 40 boys and 40 girls, aged between 6 to 10 years old (see Figure 1 for an illustration). The facial images were taken from a database at the psychology department in the University of Lancaster. All the faces, which were unfamiliar to participants, were in a frontal view with neutral expressions showing no teeth. The background was edited out using Adobe Photoshop 5.5 and was replaced with a neutral grey background. The boys’ and girls’ faces were used equally frequently across conditions and no face was used more than once across conditions, resulting in two stimulus sets. Each stimulus set consisted of 40 probe - test pairs of images, with each containing 10 probe part - test part pairs, 10 probe part - test whole pairs, 10 probe whole - test part pairs, and 10 probe whole - test whole pairs.

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.
