lead to a reflex response,…

This type of behaviour is of greatest survival benefit to animals:

With a longer life span ­ time to learn
Element of parental care of young-involves learning from parents
Living for a part of the time at…

type of reward=active and to an extent voluntary. In natural conditions-would be known as
trial and error learning.

Latent (exploratory learning)-animals will explore new surroundings and retain info about
their surroundings that is not of immediate use but may be essential to staying alive at
some future time. Young rabbits…

Primate gestation periods usually = fairly short in comparison to life span, this is because:

Primate birth canals=not large enough to allow birth of a fully developed infant.
Relatively short gestation means a fairly small skull-means can pass down birth canal
Once infant is born-relatively long period of development. During…
