Human Development The Process of Change that Occurs from Infancy to Death Examines how and why people change and how they remain the same over time Research designs: Longitudinal Cross-Sectional Cohort-Sequential
Stages of Development…. Prenatal Infancy Childhood Adolescence Adulthood Old Age
Guiding Principles…. Nature and Nurture (each influence different stages) Development is in stages Growth rates vary person to person Readiness =The child must have mastered the previous stage Critical periods
What happens if we hurry a child through a developmental sequence?
Infant Development: Birth-Age 2 o Time of rapid brain growth
Depth Perception? (by 7 months, more fear than interest)
Adaptive (survival) Reflexes.. Cough Grasping reflex Rooting reflex Sucking reflex Moro reflex
Physical Development: Ages & Stages (sometimes called developmental milestones)
Emotional Development: Even basic emotions take time to develop… Excitement Distress Delight Anger Disgust Fear
Does Imprinting occur in human beings? Attachment= Strong emotional bonds
Harry Harlow: “The Nature of Love”
Harlow’s experiment in stages Experiment on intelligence evolves The Iron Maiden Harlow’s theory of love= Contact Comfort Harlow becomes President of the APA
Less than one year later…. Monkeys not thriving! Unable to mate Violently antisocial Display autistic- like features (rocking, head- banging, biting themselves) Extreme self mutilation
Harlow identified three components to attachment: What do you think they are? Touch-Motion-Play
What about infant attachment? The Strange Situation o Secure Attachment/60-66% =mother is sensitive to infant, consistent, responsive o Resistant Attachment/ %=separation upsets child; remains upset after return o Avoidant Attachment/20% = child ignores mother- attaches to strangers same as parent o Disorganized Attachment/5- 10%= child is confused. They react in contradictory ways (seek mom but don’t look at her) Mary Ainsworth Cultures vary in what they consider appropriate responses to separation
Is there a critical period for attachment? What do you think?

Parenting Beyond Attachment Types of Parents Authoritarian: Enforce strict rules- demand obedience Permissive: Little guidance, no limits, much freedom Authoritative: firm/consistent, love & logic with responsibility Diana Baumrind
Carl Rogers: Parents give 2 kinds of support… Conditional Positive Regard= Parents show love only when child behaves in certain ways. Unconditional Positive Regard= Parents show love – no matter “who” the child is, or how they behave. What kind of support did you receive?
What is optimal? Positive-Strict-Warm o Better self-esteem o Strong morals/values o Responsible o Resilient in times of stress Negative-Permissive-Cold o Look to escape punishment o Lower self-esteem
Goodness of fit……
