Metaphors for development: how important are experiences early in life?

The many students of development have held rather diverse views on the importance of early experience. Some gave early experiences great prominence (e.g., Freud and his followers, Kuo, 1967), while others largely rejected the pivotal importance of particular early events (e.g., Thorndike), and yet others took a more eclectic tack: Some events in certain species but not all events or in all cases (e.g., Hinde, 1974, Lehrman, 1970). The extremes among the prevailing views are often characterized metaphorically. I propose to do this, then to examine the kinds of situations the metaphors describe, and inquire into their generality and usefulness. Clearly this runs the risk of undue simplification, but there is, I believe merit in occasionally ignoring some of the subtleties that usually must concern us.

Compensatory responses of goat mothers to their impaired young.

The behaviour of a mother goat towards her young normally compensates for differences between them in their vigour at birth. Weakening the first-born with drugs still does not prevent its getting equal access to the udder, though weakening the second-born may render it so much less vigorous that maternal compensation does fail. When the mother is unable to distinguish her kids by sight or smell, she is unable to modulate her responses to the kids and then the more vigorous kid always establishes priority of access to the bladder. We conjecture that this is what normally occurs under harsh environmental conditions where the mother's milk supply is occasionally inadequate for two kids.
