Table 1.

Calculated IP scores from the initial and redetermined delay discounting curves and resulting ΔIP values (mean ± SEM) in socially housed female and male monkeys.

Sex	Social Status	Indifference point(s)
		Delay to larger food delivery
		IP	re-IP	ΔIP
Male	Dominant	39.35 ± 12.91	54.43 ± 20.02	15.075 ± 12.80
	Subordinate	38.43 ± 10.54	59.85 ± 16.34	21.42 ± 10.45
Female	Dominant	37.65 ± 9.51	69.54 ± 14.74	31.90 ± 9.43
	Subordinate	54.73 ± 9.52	72.71 ± 14.75	17.98 ± 9.34

IP represents first determination.

re-IP represents the second determination.

ΔIP is the difference between IP and re-IP.
