Classic Studies That Shaped Psychology
Overview
Developmental Psychology Lecture 10 introduces the foundational studies that have significantly influenced modern understanding in the field of psychology, focusing on attachment theory and its implications for human relationships throughout the lifespan.
Lecture Outline
Key topics addressed include:
Attachment theory: This foundational concept explains the dynamics of long-term relationships between humans, focusing particularly on how early bonds with caregivers affect later relationships.
Romanian orphanages and their impact: This addresses the consequences of institutionalization on attachment and development, as seen through behavioral and electroencephalogram (EEG) studies.
Attachment from adolescence to adulthood and its implications in relationships: The importance of secure attachment styles during childhood for fostering healthy adult relationships.
Attachment as an adaptive trait: This perspective posits that attachment behaviors are evolutionarily advantageous, enhancing survival.
Developmental Psychology
Definition:
Developmental psychology is the scientific study aimed at understanding human change throughout the lifespan. It integrates findings from various disciplines within psychology, anthropology, sociology, and biology to comprehend how people develop physically, cognitively, and emotionally.
Focus areas:
Nature vs. Nurture: How genetic predispositions (nature) interact with environmental influences (nurture) to shape individual development.
Initially concentrated on infants and children, but now encompasses the entire lifespan, including adolescence, adulthood, and old age.
Areas of study include typical and atypical development, examining disorders and developmental milestones.
Disorders Discussed:
Autism Spectrum Disorder (ASD): A neurodevelopmental disorder characterized by difficulties in social interaction, communication, and restricted or repetitive patterns of behavior.
Attention Deficit Hyperactivity Disorder (ADHD): A condition marked by persistent patterns of inattention and/or hyperactivity-impulsivity.
Genetic syndromes: Such as Down syndrome and Williams syndrome, each with distinct developmental profiles and challenges.
Examination of various theoretical perspectives on developmental stages includes Erikson's psychosocial stages, Piaget's cognitive development theory, and Vygotsky's sociocultural theory.
Social Development and Attachment
The first emotional bond typically formed is between an infant and their primary caregiver, usually the mother, laying the foundation for future personal relationships. This bond is characterized by:
Intense emotional connections and behaviors
Infants instinctively seek proximity to their caregiver when they are upset or threatened, a behavior that is essential for survival.
Responsive caregiving leads to secure attachments while neglect or inconsistency might result in insecure attachment styles.
Behavioral Approach to Attachment
Dominant in the 1950s, the behavioral approach suggested that attachment was primarily a byproduct of feeding practices. However, contrary evidence emerged:
Harry Harlow's Research (1962): Studied infant rhesus monkeys separated from their mothers in an experimental setup. The key finding was that these monkeys preferred to cling to cloth 'mothers' that offered comfort rather than wire 'mothers' that provided food. This underscored the significance of emotional comfort over mere nourishment in establishing attachment.
John Bowlby’s Attachment Theory
Bowlby's Theory (1969):
Bowlby posited that the formation of secure emotional bonds with caregivers is crucial for survival and emotional development.
Suggested that infants come equipped with innate behaviors (crying, cooing) designed to attract caregiver attention, promoting proximity.
His findings parallel Harlow's research, emphasizing that feeding is not the primary basis for forming attachments.
Stages of Attachment (Bowlby)
Pre-attachment Phase (0-2 months): Babies recognize caregivers but have not yet formed strong attachments.
Attachment in the Making (2-6 months): Infants develop a preference for familiar caregivers.
Clear-Cut Attachment (6 months to 3-4 years): Separation anxiety becomes evident when a caregiver leaves.
Goal-Directed Partnership (3-4 years onwards): Children begin to form attachments with others and understand the availability of their caregivers, indicating a more complex social development.
Romanian Orphanages
Historical Context of Care: Under Nicolae Ceaușescu, strict policies resulted in the abandonment of many infants. Following the Romanian Revolution (1989), investigative reports showed severe neglect, malnutrition, and a lack of emotional support and stimulation in these orphanages.
Consequences for Children Raised in These Environments:
Children exhibited severe developmental delays and abnormal social-emotional behaviors, often linked to lack of consistent caregiving.
Effects of Lack of Attachment
Developmental implications revealed in various studies:
Exhibited rocking behaviors and self-harming tendencies, reflecting signs of psych problems and abnormal attachment behaviors that mirror the behaviors seen in Harlow's monkeys exposed to maternal deprivation.
Bucharest Early Intervention Project (BEIP)
A twelve-year longitudinal study assessing 136 abandoned children across Romanian institutions.
Two groups were compared: those placed in foster care versus those remaining in institutional care, with a control group sourced from families.
Findings from the Study:
Longer institutionalization correlated with:
Lower IQs, which decline further with age.
Slower language acquisition leading to impaired social interactions.
Impaired executive functions affecting memory and problem-solving.
Higher occurrences of psychiatric disorders, particularly anxiety and depression, among institutionalized children.
Sensitive Period for Attachment
Support for a sensitive period around 2 years old for the formation of attachment:
Early foster care (< 24 months) is associated with normal brain activity (EEG) by age 8, indicating the importance of early nurturing environments.
In contrast, institutionalized children exhibited atypical brain activity, suggesting long-term impact from neglect.
Long-Lasting Effects
Follow-up studies indicated:
Reduced electrical activity and white matter in children aged from institutional backgrounds, indicating potential deficits in cognitive and emotional processing.
Emphasized the psychosocial value of high-quality foster care for optimal long-term brain functioning and emotional adjustment.
Attachment Styles
Varieties of attachment styles identified, influenced by early experiences:
Secure: Positive self-view and belief in positive relationships; adept at seeking and receiving comfort effectively.
Dismissive: Positive self-view but negative view of others; tends to avoid closeness in relationships.
Preoccupied: Negative self-view and high dependence on others; often resulting from inconsistent care.
Fearful: Negative views of self and others; keenly inhibited by fear when approaching social interactions.
Adolescent Attachment
A critical period for attachment is during adolescence (16-25 years), marked by emotional and cognitive changes. Debate surrounds the impact of parental influence versus peer relationships on attachment and social skills.
Secure attachment in adolescence is linked to healthier relationships and better conflict resolution skills.
Summary of Findings
Attachment theory, shaped by Harlow’s and Bowlby’s work, underlines the dire consequences of lack of attachment in early years, which can lead to significant developmental challenges.
Sensitive periods are critical for development; findings support early interventions such as foster care showing marked improvements in developmental trajectories.
Adlerian principles connect parental behaviors with attachment styles in adolescents, illustrating that attachment styles govern reactions to stress and interpersonal relationships, emerging as adaptive traits throughout life.
