3. The Automated Inkless Fingerprint<br />

Imaging software (Nanakorn et al., 2006; 2007; 2008).<br />

4. MI questionnaire (Sintuwong, 2002; with<br />

written permission) which consists of 80 questions<br />

of the 8 MI categories (10 questions for each MI)<br />

scoring in 5 levels from 0 to 4 (This is not like me<br />

at all = 0, This is a bit like me = 1, This is<br />

sometimes like me = 2, I am like this more often<br />

than not = 3, I am always like this = 4).<br />

Sample collection: Prior to answering the<br />

MI questionnaire and scanning of fingertips, signed<br />

informed consents were obtained. Each subjectûs ten<br />

fingertips were scanned using the fingerprint sensor<br />

coupled with the Automated Inkless Fingerprint<br />

Imaging Software. The scanning method is described<br />

elsewhere (Nanakorn et al., 2007; 2008). Briefly,<br />

researchers performed scanning by touching each<br />

subjectûs fingertips on a touchpad of the fingerprint<br />

sensor, starting from the left hand; thumb, index,<br />

middle, ring, little fingers, followed by the right<br />

fingers of little, ring, middle, index, and thumb.<br />

These fingertipsû images are stored into a data<br />

base as a portable digital format (PDF) file<br />

before printing. Subjects also answered the MI<br />

questionnaire by themselves.<br />

Data analyses: Types of fingerprint<br />

patterns were identified by the first author according<br />

to the standard method set by Cummins and Midlo<br />

(1943). Four main types of fingerprint patterns were<br />

classified as whorl, ulnar loop, radial loop, and arch.<br />

Reliability of the MI questionnaire was analyzed<br />

using the alpha Cronbach. Sex difference of each<br />

mean MI score was analyzed using an independent<br />

sample t-test. Relationships between types of<br />

fingerprint pattern and means of each MI score were<br />

analyzed using an analysis of variances (ANOVA)<br />

and the independent sample t-test. The SPSS for<br />

Windows version 17.0 (SPSS Inc. Chicago, IL, USA.)<br />

was used for statistical analyses at 95% level of<br />

confidence.<br />

Results<br />

Demographic characteristics<br />

Seventy two subjects were 43 males and<br />

29 females who identified themselves for training<br />

in Computers (20 persons = 27.8%), Physics (20<br />

persons = 27.8%), Mathematics (18 persons = 25.0%),<br />

and Biology (14 persons = 19.4%).<br />

Reliability<br />

Cronbachûs alpha of the 80 questions was<br />

equal to 0.917<br />

Multiple intelligence<br />

Descriptive analysis of mean scores of each<br />

MI by sex found that the intrapersonal intelligence<br />

of male subjects was higher than other MI (29.1+4.7;<br />

mean + standard deviation). The second and the<br />

third highest mean scores were logical-mathematical<br />

intelligence and musical intelligence (28.7+4.2,<br />

26.8+6.9, respectively). Female subjects also had<br />

the highest score of intrapersonal intelligence<br />

(27.5+3.5) followed by spatial intelligence (25.4+4.8),<br />

logical-mathematical intelligence (25.4+4.2), and<br />

interpersonal intelligence (25.3+4.3). Sex differences<br />

of MI mean scores analyzed by the independent<br />

sample t-test showed that male subjects had<br />

significantly higher mean MI scores than those of<br />

females [t (71)<br />
