| A total of 120 subjects were observed in this experiment.24 subjects were the pupils in Grade 5 in the primary school (the mean age is 11±1 years old), 24 ones of the students in grade 2 in junior middle school (the mean age is 14±1 years old), 24 ones of the students in Grade 2 in senior middles school (the mean age is 17+1 years old), 24 college students in Grade 2 (the mean age is 20±1 years old), and 24 postgraduates (the mean age is 25±1 years old).In each grade the male and the female was50%. With the method of Signal Detection of Theory (SDT), the study investigated into how the level of processing and time interval of recognition affect the result of the facial recognition and the developmental tendency of facial recognition. The experimental materials were 60 one-inch-photos of adult male and female (the mean age was 19±1 years old),photos with special marks (e.g. birthmark or wiring an earring) had been gotten rid of prior the experiment. The photos were two parts: one was 18 memorization photos (the photos of male and female are 9 each), the other was 36 recognition photos which included 18 memorization photos and 18 photos that did not be memorized by subjects. All the procedure was performanced by computer. The experimental designs were:2(processing level: simple processing , deep processing) x2(recognitive style: immediate recognition, delayed recognition) x5(age: Grade 5 in the primary school, grade 2 in junior middle school, Grade 2 in senior middles school, college students in Grade 2, postgraduates). The dependent variables were the index of discrimination (d'), the criterion of judgement (β) and the subjects?reflection time. The results are as follows: (1) the score of (d'=2.65) under the deep processing is higher than the score (d'=2.34) under simple processing, but the difference is not significant; (2) the score of recognition (d'=2.72) under immediate recognition is higher than the score under delayed recognition (d'=2.28, p |
