A criticism of learning theory is that it is largely based on studies of non-human animals such as Skinner’s research with pigeons
Behaviourists believe that humans are no different from other animals in terms of how they learn.
Therefore, they argue that it is legitimate to generalise the results from animal studies to humans.
However, whilst some aspects of human behaviour can be explaining by conditioning, not all behaviour can, especially a complex behaviour like attachment
What do learning theory studies being based on non-human animals suggest about attachment?
This suggests that learning theory may present an oversimplified view of human attachment.
The main limitation of learning theory as an explanation for attachment is that it suggests that food is the key element in the formation of attachment.
However, a range of animal studies have shown that young animals do not necessarily attach to (or imprint on) those who feed them.
Lorenz’s geese imprinted before they were fed and maintained these attachments regardless of who fed them.
Harlow’s monkeys attached to a soft surrogate in preference to a wire one that dispensed milk.
What does food not being the key element in the formation of attachment suggest ?
This suggests that attachment does not develop as a result of feeding. Therefore, the same must be true of humans (i.e. food does not create an attachment bond) because behaviourists believe that humans and non-humans are equivalent.
Research with human infants also suggests that feeding does not appear to be an important factor in humans
For example, Schaffer and Emerson’s (1964) study found that 39% of infants developed a primary attachment to the person who did not feed them.
What does the 39% of infants developing a primary attachment to someone who didn't feed them suggest?
These findings are a problem for the learning theory as they suggest that feeding is not the key element to attachment and so there is no unconditioned stimulus or primary drive involved.
Learning theory may not provide a complete explanation of attachment, but it has some value.
Infants do learn through association and reinforcement, but food may not be the main reinforcer.
It may be that attention and responsiveness from a caregiver are important reinforcers that assist in the formation of attachment.
What do reinforcers such as attention and responsiveness suggest?
These reinforcers were not part of the learning theory account but may be able to provide some explanation of attachment.
