Twenty-one faces of famous personalities (including the 10 faces used in Expt 2; see Appendix 2) were caricatured at three levels of exaggeration (+50, 0 and -50 per cent), giving a total of 63 caricatures that were used as primes in the 'Yes' response trials.
A familiar target name was preceded by its corresponding caricatured (+50 per cent) face prime.
The prime faces in the 'No' response trials were familiar faces caricatured at three levels of exaggeration (+50, 0 and -50 per cent).
The original hypothesis stated that caricatured faces should produce more self-priming than veridical faces or anti-caricatures.
We reasoned that if this conception is correct, then we should be able to demonstrate that caricatured face primes produce more self-priming than veridical and anti-caricatured face primes.
Experiment 3 focused on a comparison between the conditions using the same person's face caricatured at +50, 0 and -50 per cent, with a minimal number of repetitions of each caricatured face.
The present experiment used jumbled and intact versions of familiar (public) and unfamiliar faces in which distinctiveness was manipulated by using caricatured and veridical representations.
Mean RT (ms) 719 597 836 718 SD 149 112 304 201 From this table it appeared that the caricatured stimuli were responded to more slowly than the veridical stimuli.
This revealed a significant main effect of representation (F(1,14) = 22.39, p [less than] .001); caricatured stimuli again took longer to classify as jumbled than veridical stimuli.
The present study has examined the performance with caricatured and veridical versions of a set of faces on a face classification task.
The present experiment is the first to explore the performance with caricatured and veridical stimuli when distinctiveness is a disadvantage.
Consequently, the use of caricatured and veridical versions of the same faces reduces the interference from confounding variables when examining distinctiveness effects.
