I don’t find this so strange because all geese look almost the same to me. Perhaps more important is that adult sexual preference may be established at this early time, though it only much later appears in behavior.
“A jackdaw for which the human has replaced the parental companion, will thus direct its awakening sexual instincts not specifically towards its former parental companion, but … towards any one relatively unfamiliar human being. The sex is unimportant, but the object will quite definitely be human. It would seem that the former parental companion is simply not considered as a possible ‘mate’.”
Some studies have shown that after such contact, some of those birds will eventually mate with other members of their species. However, this phenomenon is still such a serious problem in repopulating endangered species that it has become the standard policy to minimize human contact with chicks, lest their preference for people lead them to later refuse to mate with their peers. Could such delays be relevant to human sexual preferences?
All of this could help to explain why we evolved our extended infantile helplessness: children who too soon went off by themselves would not have been wise enough to survive—and so, we had to extend the time for learning from imprimers instead of from doing risky experiments.
§2-8. Who are our Imprimers?
A JACKDAW, seeing Doves in a place with much food, painted himself white to join them. The Doves, as long as he did not speak, assumed that he was another Dove and admitted him to their cote. But when one day he forgot not to speak, they expelled him because his voice was wrong—and when he returned to his Jackdaw tribe they expelled him because his color was wrong. So desiring two ends, he obtained neither.
How many Imprimers can a person have? Many young children have only one, while others may have two, three, or more. Then when a child has several of them, are those attachments interchangeable—or could they serve different functions and goals? If a child forms several sets of ideals, would that enrich its personality—or would it impair its development because those inconsistencies prevent it from forming a single coherent self-image?[29]
When do attachments begin and end? Even young infants soon start to behave in distinctive ways when in their mothers’ presence. However, it is usually not till near the first year’s end that the child protests against separation—and begins to learn to become disturbed at a sign that Imprimer intends to depart—e.g., reaching for an overcoat. This is also the time when most children begin to show fears of unusual things. Both this and that fear of separation begin to decline in the child’s third year—so that now the child can be sent to school. However, we do not see the same decline in the roles of those other, self-conscious, attachment-based feelings. These persist for longer times and sometimes, perhaps, for the rest of our lives.
John Bowlby: “During adolescence … other adults may come to assume an importance equal to or greater than that of the parents, and sexual attraction to age-mates begins to extend the picture. As a result individual variation, already great, becomes even greater. At one extreme are adolescents who cut themselves off from the parents; at the other are those who remain intensely attached and are unwilling or unable to direct their attachment behavior to others. Between the extremes lie the great majority of adolescents whose attachments to parents remain strong but whose ties to others are of much importance also. For most individuals the bond to parents continues into adult life and affects behavior in countless ways. Finally in old age, when attachment behavior can no longer be directed to members of an older generation, or even the same generation, it may come instead to be directed towards members of a younger one.”
What happens in other animals? In those that do not remain in herds, attachment frequently only persists until the offspring can live by themselves. In many species it’s different for females; in many species the mother will actively drive the young ones away as soon as a new litter is born (perhaps because of evolutionary selection against inbreeding)—while in other cases attachment will stay until the time of puberty or even later for females. In Attachment (p182) Bowlby mentions a phenomenon that results from this:
“In the female of ungulate species (sheep, deer, oxen, etc.), attachment to mother may continue until old age. As a result a flock of sheep, or a herd of deer, is built up of young following mother following grandmother following great grandmother and so on. Young males of these species, by contrast, break away from mother when they reach adolescence. Thenceforward they become attached to older males and remain with them all their lives except during the few weeks of each year of the rutting season.”
Of course, other species evolve different strategies that are better suited for different environments; for example, the size of the flock may depend on the character and prevalence of predators, etc.
Why should we need Imprimers at all—and why should we be so exclusive in how our brains make us choose them? Why not simply elevate goals in response to anyone’s censure or praise? There’s an excellent reason why we evolved to be selective about this—for if any stranger could program your goals, you’d be in danger because strangers are less likely than your close relatives are to be concerned for your welfare.
However, ‘welfare’ can mean different things. For example, Bowlby argued that our attachments mainly promote our children’s physical safety. Here’s a paraphrase of his argument”
“That protection from predators is by far the most likely function of attachment behaviour is supported by three main facts. First an isolated animal is much more likely to be attacked than is one that stays bunched together with others of its kind. Second, attachment behavior is especially easy to arouse in animals that, by reason of age, size, or conditions are especially vulnerable to predators. Third, this behavior is strongly elicited in situations of alarm, which are commonly ones in which a predator is sensed or suspected. No other theory fits these facts.”
Here, Bowlby’s main concern was to refute the then popular view that attachment’s primary function was to ensure a dependable source of food. Instead, he argued that physical care (including nutrition) did not play a crucial role in attachment and security was the more influential. I suspect that this was largely correct for animals, but does take into account how human attachments so strongly promote our acquiring values and high-level goals.
§2-9. Self-Models and Self-Consistency
To solve a hard problem, one must work out a plan—but, then, you need to carry it out; it won’t help to have a multi-step plan if you tend to quit before it is done. This means that you’ll need some ‘self-discipline’— which in turn needs enough self-consistency that you can predict, to some extent, what you’re likely to do in the future. We all know people who make clever plans but rarely manage to carry them out because their models of what they will actually do don’t conform enough to reality. But how could a trillion-synapse machine ever become predictable? How did our brains come to manage themselves in the face of their own great complexity? The answer must be that we learn to represent things in extremely simple, yet useful ways.

Multiple attachments are reported in Schaffer, H.R. and Emerson P.E. (1964)
