the idea that children are born with an innate (instinctively) tendency to form attachments with their parents in order to increase chances of survival
infants must form an attachment during the critical period which is between 3-6months
bowlbys acknowledged that infants can form attachments after this period (up to 3 years) but successful attachment would be increasingly difficult after this initial period
if not formed within this time frame the child would be damaged for life socially, emotionally,intellectually and physically
- there's supporting evidence: lorenz supported criticalperiod and attachment being an innateprocess - based on biological processes not through learning , critical period for geese is 12-17 hours
- Harlow supports the internalworking model - baby monkeys with insecureattachments with mothers became insecure mothers themselves when they grew up
- theory has negativeimplications for working mothers (social sensitivity)
- cupboardlove: alternative explanation of attachment that the environmentnotbiology creates attachment
- lorenz: lacksexternalvalidity/generalisability as the study focuses on geese not humanattachment - they're different in evolutionary terms
- kagan1984: a child'spersonality affects how a child forms relationships whether they're securely or insecurely attached
- lacks temporalvalidity as there's alpha bias as it suggests that women should be the primarycaregiver and the father should provide. in modern society men are expected to do an equal amount of childcare compared to women
