Note: Bolded values indicate a Spearman correlation coefficient with r > 0.6 using n = 8. P-values for these correlations are indicated in smaller print; nominally significant P-values are underlined. Abbreviations: LHab = habituation of locomotor activity on LRN procedure. Rs = active responding, SRHab = habituation of active responding on SR procedure. RT = reaction time, SD = reaction time standard deviation, DevM = deviation from the mode, Correct = proportion correct, Prem = premature responses on the CRT procedure. AUC = area under the obtained discount curve, k = describes steepness of best fitting hyperbolic discount curve.
