Neurochemical Substrates:

Neurolocalization:

Elicitors:

-Physical elicitor: detectable (perhaps, especially, visibly) resources; resources desired by opposite sex may be most eliciting -Situational elicitors: general detectability of resources/resource holding being subject of general knowledge; display within mating contexts

Function:

Detection of physical (external/non-somatic) resource inequality: most likely serves to permit detection of one's own non-competitiveness and/or increase motivation for making oneself more competitive as a mate (intrasexually). Permits/motivates identification of rivals near to one's own competitiveness level/those with whom intrasexual competition would not likely yield an advantage to one.

Outputs:

-Cognitive/Emotional/Psychological outputs: envy towards holder of greater resources, desire for greater resource holding oneself/diminishing of greater resource-holder's resource -Behavioral outputs: calibrated various actions taken to counter competitive advantage of other(s) of same sex holding greater resources, especially in ways that would increase one's own competitiveness intrasexually in mateship competitions

Abstract: Hyphenating or keeping premarital surname for all U.S. destination brides marrying in Hawai’i in 2010 was highly, positively correlated with a state-level women’s income measure (r = .78, p < .000) and the analogous statistic for men (r = .64, p < .000), by bride’s state of residence. The women’s measure, only, remained significant when both predictors were used, together, to predict retention/hyphenation (i.e., under regression of both predictors). The interaction of state Gini coefficient and the women’s income measure was positively predictive in a regression including the interaction components as predictors (adjusted-R2 = .66). None of several other predictors suggested by previous research or related to Gini index or income, testable using available, state-level data, were predictive (under regression) alongside the women’s income measure. The older the bride, from any jurisdiction, the more likely she is to hyphenate or keep her sur-name (χ2 for linear trend = 1754.65, p < .000). These analyses comprise a nearly direct replication of previous work, adding novel analyses. Taken together, the original and replicated study may show evidence consistent with a general practice of women taking into account local economic factors, in marital surname decision-making.

Supporting Evidence is evidence that suggests that this trait is an Evolved Psychological Adaptation (EPA) - i.e., that it has been shaped by natural selection to solve a particular adaptive problem.
