Once the Strange Situation was developed, Ainsworth et al (1978) used it to assess 106 infant-caregiver relationships, & the findings indicated 3 patterns of attachment type, ie the children fit into one of the 3 categories, each with distinct behaviours in the SS:
1-Secure (66% of sample)
2-Insecure-avoidant (22%)
3-Insecure-resistant (12%)
Differences in attachment type are caused by primary caregiver's sensitivity towards child:
If responsive/ sensitive- secure
If unresponsive/ insensitive- avoidant
If inconsistent- resistant
Ainsworth et al 1978 findings: 1
Secure Attachment & Separation Anxiety- some upset when mother leaves, but easy to sooth.
Insecure-avoidant Attachment & Separation Anxiety- indifferent, infant shows no sign of distress when mother leaves & is unconcerned.
Insecure-avoidant Attachment & Reunion Behaviour- avoids contact, infant shows little interest when mother returns.
Insecure-resistant Attachment & Reunion Behaviour- seeks then rejects, child approaches mother but resists contact & may even push her away.
Ainsworth et al 1978 findings: 4
Secure Attachment & Willingness to explore- high, will use the mother as a safe base to explore their environment.
Insecure-avoidant Attachment & Willingness to explore- high, doesn't look back to mother for security.
Insecure-resistant Attachment & Willingness to explore- low, lacks confidence in exploration of environment.
Hazan & Shaver's 1987 Love Quiz Study:
Placed a 'love quiz' in an American small-town publication, & the quiz asked questions about current attachment experiences & about attachment history, to identify current & childhood attachment types.
The questionnaire also asked questions about attitudes towards love.
They analysed 620 responses, 205 from men & 415 from women.
Hazan & Shaver's 1987 Love Quiz study findings:
When analysing self-report of attachment history, they found that the prevalence of attachment style was similar to that found in infancy.
Eg, 56% were classified as secure, 25% as avoidant, 19% as resistant.
Found a positive correlation between attachment type & love experiences.
Evaluation for attachment types- strength:
There's evidence that Ainsworth's attachment types are reliable & enduring.
Hazan & Shaver (1987) conducted the Love Quiz study & found that early attachment type correlated with the quality of adult romantic relationships & even divorce rates.
Indicates the attachment types identified by Ainsworth are a stable feature of emotional development.
Evaluation for attachment types- strength:
There are practical applications of Ainsworth's attachment types research.
Identifying insecure attachments can be used to help caregivers be more responsive to their infants & therefore change them from insecure to secure.
Improving children's lives is a huge strength, as it has the potential to increase well-being, both short & long term, & break the cycle of poor parenting.
Evaluation for attachment types- weakness:
Not all attachments fit into the 3 categories.
Main & Solomon (1986) identified a fourth attachment type, which they called insecure-disorganised, which has a different pattern in the Strange Situation, eg they can show signs of both strong attachment & then avoidance.
Indicates that Ainsworth's account of different attachment types was incomplete & needed to be reviewed to include this 4th type.
Evaluation for attachment types- weakness:
The method used to assess attachment types (the strange situation) is flawed.
Are problems with the assessment method, which may mean that the findings are also flawed & would mean that the theory on attachment types is inaccurate.
