Association of lottery and insurance purchase with MAOA.

<p>Logit regression is used to test the effect of MAOA on lottery and insurance purchase with control variables of age, gender, student status, and education. This table reports results using both allele and genotype models for pooled, male, and female subjects. OR refers to odds ratio and CI refers to its 95% confidence interval.</p

MAOA gene, lottery, and insurance.

<p>(A). MAOA and lottery. Subjects with the high activity allele (4-repeat allele) are significantly more likely to exhibit longshot preference than subject with the low activity allele (3-repeat allele). (B). MAOA and insurance. Subjects with the low activity allele (3-repeat allele) are more likely to exhibit preference for insurance than subject with the high activity allele (4-repeat allele).</p

The effect of AVPR1A RS3 ‘target allele’ on allocations in the DG.

<p>Percentage of children according to the number of sticker charts allocated in the DG (0, 1 or 2 and more), and the presence/absence of the ‘target allele’. Compared with non carriers, carriers are much less likely to allocate more than 2 sticker charts, and more likely to allocate nothing.</p

Salivary cortisol levels following the TSST.

<p>Area under the curve following the TSST for males and females. The rise in salivary cortisol is significant (SPSS GLM repeated measures) for men (F = 22.32 p<0.001) and for females (F = 9.04 p<0.001).</p

Methylation levels across 39 CpG sites in exon 1F for each subject.

<p>Methylation level of GR exon 1F at individual CpG sites for females (n = 46) (2A) and males (n = 46) (2B). Each point in the figure represents a single individual's percentage methylation value for each of the 39 CpG sites that were analyzed by bisulfite pyrosequencing. The points were color coded by the graph option in Excel and each color and shape represents an individual subject. The graph illustrates the marked individual differences (indicated by the shape and color of markers) in percentage methylation at each CpG site. <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0048597#pone-0048597-g002" target="_blank">Figure (2C</a>) presents the promoter sequence of exon 1F showing the CpG sites and their position. Highlighted regions represent known or putative canonical (italics) and noncanonical (not italics) NGFI-A–binding sites, with the shaded grey area indicating the beginning of the exon (following McGowan et al (23)).</p

Linear regression analysis (average % methylation).

<p>* p<0.05; **p<0.01; ***p<0.001.</p><p>The significance levels are from the Coefficient's Table from the linear regression output of SPSS. The numbers in parentheses are the SE of the unstandardized beta coefficients. Each column is a separate regression analysis representing the addition of the predictor (column 1 = sex+methylation; column 2 = only in females methylation; column 3 is methylation + serotonin transporter + ESR1 dummy variables).</p
