本研究以68只尾猕猴子代为研究对象，研究了妊娠期母亲心理社会压力与皮脊数、妊娠期长度、出生体重百分位数和存活率的不对称性之间的关系。从受孕后30天到130天，每天捕获25只怀孕雌性；43只未受压力的雌性被安置在干扰最小的条件下。后代的右手和左手之间的总核间真皮脊数的差异被用来衡量理论上发生在产前应激源存在下的发育紊乱。应激组子代皮纹不对称性显著高于非应激组（平均不对称性分别为7.3±2.8和5.4±2.5,t = 2.85, p < 0.01）。虽然母体应激本身与妊娠期长短、出生体重或存活率无关，但高度不对称（8-13个残余真皮脊）与围产期死亡率增加显著相关。
The relationships between maternal psychosocial stress during pregnancy and asymmetry in dermal ridge count, gestation length, birth weight percentile and survival were examined in 68 pigtailed macaque offspring. Twenty-five pregnant females were stressed daily by capture from 30 through 130 days postconception; 43 control unstressed females were housed under conditions of minimal disturbance. The difference between total intercore dermal ridge counts between right and left hands of the offspring was used as a measure of the perturbed development that theoretically occurs in the presence of a prenatal stressor. Dermatoglyphic asymmetry was significantly higher in the stressed offspring than in the unstressed group (mean asymmetry = 7.3 ± 2.8 and 5.4 ± 2.5, respectively; t = 2.85, p < 0.01). Although maternal stress alone was not related to differential gestation length, birth weight, or survival, high asymmetry (8–13 residual dermal ridges) was significantly associated with increased perinatal mortality.
