When assessing the difference in reaction time between males (M=968.60, SD=443.50) and females (M= 967.31 SD= 414.33), Levens test was violated. There was no significant difference found, t(495)=0.03 p=0.49.

In analyzing the difference in accuracy in males (M= 79.91 SD= 18.62) and females (M=77.45, SD=18.12), Levene’s test was violated therefore equal variances were assumed. Similarly the results were found insignificant,

t(495)=0.125 p=0.11. the analysis of the 2D:4D ratio between males( M=0.96,

SD= 0.055) and females (M=0.98,SD=0.05) differentiated itself as these results were found to be significant, t(495)=3.92 p

A Pearson’s correlation (table 3) was conducted to assess the relationship between gender and accuracy (r=0.023 p=.62), reaction time and 2D:4D ratio (r=0.071 p=0.11. Both correlations between accuracy and reaction time as well as accuracy and the 2D:4D ratio were found to be insignificant.

The relationship between 2D:4D ratio and reaction time found a small statistical significance (r=0.090 p=0.046)

Discussion:

These results as well as results found from Chipman(1999), Kalmady (2013) support the hypotheses that females perform better with working memory tasks than males, females have a larger 2D:4D ratio in contrast to males and there is a correlation between the 2D:4D digit ratio and working memory reaction time between genders.

The results in support of our hypothesis found a negative correlation which meant that the longer the ratio the quicker (less time in milliseconds). It was shown that females had a larger 2D4D ratio and therefore a faster reaction time.

The results of the T-test showed that females have a lower accuracy rate than males.

Evardone and alexander(2007) analysed the link between sex linked behaviours and digit ratio and there study found that 2D:4D is a direct correlate of prenatal sex steroids. Their study showed that women with more masculine prenatal hormone levels and women with more female prenatal hormone levels result in varying digit ratios.
