Abstract

27-, 29-, 39-, or 52-week-old normal (N=73) and premature infants (N=37) were compared to examine the utility of Fagan Test of Infant Intelligence(FTII). There was no sex difference on recognition memory (t(108)=.19, p<.890). Therefore, infants' performances were analyzed by group(2) X age (4) ANOVA. Only the group main effect was significant (F(1,102)=7.942, p<.006) . The recognition rate in NI CU group was 54.59% (SD=7.92) which was significantly lower than that of the normal group, 59.59% (SD=7.26). Even though it was not significant there was a trend that the recognition memory was increasing with age : 56.39% (SD=8.87), 56.84% (SD=7.16), 58. 20% (SD=6.71), 62.14% sss(SD=7.18) for 27-, 29-, 39-, and 52-week-olds repectively. The correlation between the recognition rate and the standard deviation in the IO recognition tasks was negative, r=-.43 and the standard deviation of the recognition rate in the NICU group (M=22.97, SD=7.06) was larger than that in the normal group (M=20.53, SD=5.56) (t(108)=1.98, p<.05). It was suggested that the variance in the performance on the FTII could be another index of infant's intelligence.
