Bowlby's theory of maternal deprivation suggests if the child's monotropic attachment is disrupted during the critical period due to prolonged separation from the mother, this deprivation has negative and irreversible consequences

Maternal deprivation theory
Children whose care is disrupted in the critical period develop serious social, emotional and intellectual difficulties, limiting their ability to have positive relationships in the future
Bowlby believed that early maternal deprivation caused affectionless psychopathy and consequently, criminality!
Lewis et al - count bowlby
Through collecting qualitative data from interviews conducted with 500 juveniles, the researchers found no link between maternal deprivation and difficulty in forming relationships in later life.
This suggests that Bowlby may have made incorrect causal conclusions.
Bowlby’s 44 juvenile thieves study - methodological limitations.
researcher bias - may have phrased the interview questions in a way that influenced the respondents to reply in a certain way i.e. leading questions.
