Estimated Mean and Upper/Lower Bound of 95% Confidence Interval of Shape Parameter a in Curve Fitting Analysis

YNG = younger group; OLD = older group; AMG = amygdala; Nov = novel condition; Neg = negative condition; Pos = positive condition; LoCI₉₅ = lower bound of 95% confidence interval; UpCI₉₅ = upper bound of 95% confidence interval.

Bold type: YNG mean > OLD UpCl₉₅ and OLD mean < YNG LoCl₉₅.

For novel conditions, mean a = 3.66 in older < LoCI₉₅ = 6.17 in younger, mean a = 6.66 in younger > UpCl₉₅ = 5.27 in older; for negative conditions, mean a = 4.34 in older < LoCI₉₅ = 5.90 in younger, mean a = 6.27 in younger > UpCl₉₅ = 6.19 in older.
