Although it is a common claim in the ecological psychology literature that our perception of the environment’s affordances is influenced by socio-cultural norms, an explanation of how this is possible remains to be offered. In this paper, I outline an account of this phenomenon by focusing on the ecological theory of perceptual learning. Two main theses are defended. First, I argue that to account for how socio-cultural norms can influence perception, we must pay attention not only to the education of (...) attention but to the education of intention too. Consequently, I offer some ideas about how intention can be socio-normatively educated. Secondly, I hold that the education of intention occurs via the acquisition of habit-based preferences for particular actions. I claim that once we understand how these habit-based preferences relate to socio-cultural norms, the hypothesis that norms must be represented in the individual’s mind for them to influence affordance perception is no longer needed. If this hypothesis is on the right track, we can have an explanation for how perception can be normatively shaped and direct (non-mediated by internal representations and inferences) at the same time.

Although it is rarely named, the majority of societies in the ethnographic record demarcate a period between early childhood and adolescence. Prominent signs of demarcation are, for the first time, pronounced gender separation in fact and in role definition; increased freedom of movement for boys, while girls may be bound more tightly to their mothers; and heightened expectations for socially responsible behavior. But above all, middle childhood is about coming out of the shadows of community life and assuming a distinct, (...) lifetime character. Naming and other rites of passage sometimes acknowledge this transition, but it is, reliably, marked by the assumption or assignment of specific chores or duties. Because the physiological changes at puberty are so much more dramatic, the transition from middle childhood is more often marked by a rite of passage than the entrance into this period. There is also an acknowledgment at the exit from middle childhood of near-adult levels of competence—as a herdsman or hunter or as gardener or infant-caretaker. (shrink)

Considerable research on helpers-at-the-nest demonstrates the positive effects of firstborn daughters on a mother’s reproductive success and the survival of her children compared with women who have firstborn sons. This research is largely restricted to agricultural settings. In the present study we ask: “Does ‘daughter first’ improve mothers’ reproductive success in a hunting and gathering context?” Through an analysis of 84 postreproductive women in this population we find that the sex of the first- or second-born child has no effect on (...) a mother’s fertility or the survival of her offspring. We conclude that specific environmental and economic factors underlay the helpers-at-the-nest phenomenon. (shrink)
