Attachment Studies Flashcards
Evans and Porter Aim
Investigate whether interactional synchrony and reciprocity affect attachment quality in infants and caregivers
Evans and Porter Setting and Sample
Lab, 101 infants and their mothers- 53 female, 48 male, American suburb
Evans and Porter Procedure
Mother and babies invited into laboratory 3 times, at 6,9 and 12 months old
Play with toys for 15 mins- videoed, and communication was assessed. At 12 months the attachment was assessed with strange situation
Evans and Porter Findings
Secure attachment linked to most reciprocal and interactional synchrony interactions in earlier months
Evans and Porter Conclusion
Attachment affected by amount of communication
Evans and Porter Evaluation
Controlled, no extraneous variables, increases internal validity
Demand characteristics, social desirability and evaluation apprehension, decreases internal validity
Volunteer bias, decreases population validity
Isabella et al Aim
Does interactional synchrony affect attachment
Isabella et al Procedure
Observed 30 mothers and infants together and assessed degree of synchrony, and quality of attachment
Isabella et al Findings
High levels of synchrony= better attachments
Isabella et al Conclusion
Interactional synchrony is important for development
Isabella et al Evalution
Demand characteristics, decreases internal validity
Controlled, increases internal validity
Geiger Aim
Role of father
Geiger Conclusion
Father’s play is more exciting, mothers more nurturing
Lamb Aim
Role of father
Lamb Conclusion
Fathers can be maternal, sensitive responsiveness isn’t a biological ability
Hardy Aim
Role of father
Hardy Conclusion
Males are less suitable as primary caregivers as are less able to detect distress
Lucassen Aim
Role of father
Lucassen Findings and Conclusion
Meta-analysis of strange situation showed high levels of sensitivity associated with good father- infant attachments
Schaffer and Emerson Aim
Role of father
Schaffer and Emerson Findings and Conclusion
Longitudinal, in 1964 1/3 primary attachment was father, 50 years later, stronger attachment formed earlier
Evaluation of Father’s role
Fatherless families and single dads- trauma could affect, decreases internal validity
Social desirability, decreases internal validity
Evaluation apprehension, decreases internal validity
Natural environment, more extraneous variables, decreases internal validity
Longitudinal studies, increases reliability
Schaffer and Emerson Aim
Assess patterns of attachment – make stages of attachment
Schaffer and Emerson Setting and Sample
Field, 60 babies, 31 male, 29 female, and mothers. All from Glasgow & working class
Schaffer and Emerson Procedure
Longitudinal study, interviews. Separation protest measured- left alone. And stranger anxiety- assessed by researcher
Schaffer and Emerson Findings
Asocial stage, indiscriminate attachment, specific attachments, multiple attachments
Fear of strangers starts after 21 weeks
Schaffer and Emerson Conclusion
Pattern of attachments
Schaffer and Emerson Evaluation
Evaluation apprehension and social desirability, decreases internal validity
Naturalistic environment, decreases internal validity/ increases ecological validity
Longitudinal study, increases reliability
Evaluation of Schaffer’s Stages
Asocial stage babies have low mobility anyway, decreases internal validity
Lorenz Aim
Investigate imprinting on young geese
Lorenz Procedure
Goose eggs- incubator or naturally with mother
Made sure he was the first thing the incubator group saw after birth
Marked geese to distinguish
Placed in box to see who they would return to- all muddled
