A series of six experiments are reported in this thesis: four investigated developmental trends in configural face processing using an interference paradigm, and two investigated developmental trends in face gender classification. Results from experiments 1-3 indicated that developmental differences in face recognition depend on the type of stimulus employed. Unlike young children, older children and adults suffered a significant decrease in both accuracy (face identification) and response time from whole, inner, and outer face recognition to whole, inner, and outer meld face recognition - where meld faces represent configurally disrupted faces. Results from experiment 4 indicated that this effect was significantly reduced when part faces rather than whole faces where presented at the encoding stage. These findings were interpreted using a concept of featural and configural processing within Valentine's (1991) face-space model. Results from experiments 5-6 indicated that unlike face recognition, configural disruption did not affect differences in performance across the age span. However, in line with the face recognition experiments, an outer face advantage was observed across stimulus type. These results were further accommodated into Valentines face-space model, opening up opportunity for further lines of enquiry.
