Theories
Good theory criteria: Logically Emperically sound Clear, testable and parsimonious Cover a reasonably large area of science
and should integrate previous research

Theories of Human Development
A developmental theory is a systematic statement of principles and generalizations that provides a framework for understanding how and why people change as they grow older.

Theories of Human Development
Psychoanalytic Theory A theory of human development irrational, unconscious drives and motives
underlie human behavior. often originating in childhood Psychoanalytic theory originated with
Sigmund Freud (1856– 1939)

Psychoanalytic-Freud
Optimum development Emphasis on the formative role of the
early experience
What do you think? How important are the first 5 or 6 years in shaping our personality?

A student of Freud’s Followed Freud’s stage theory Development = Inner instincts X
Cultural/social demands Throughout the lifespan Development occurs as individuals
resolve 8 crises

Theories of Human Development
Behaviorism Observable behavior Conditioning
![Page 15: THEORIES IN HUMAN DEVELOPMENT. Theories… what are they good for? Understanding Generalization A basis for decision making Predicting future events](https://reader030.vdocument.in/reader030/viewer/2022032518/56649ccc5503460f9499551d/html5/thumbnails/15.jpg)
The Elements of Classical Conditioning
Unconditioned stimulus (US) and unconditioned response (UR) Naturally occurring stimulus (US) evokes a
naturally occurring response (UR) Neutral stimulus (NS) Pairing neutral and unconditioned stimuli
NS and US presented together NS becomes a conditioned stimulus (CS)
that produces a conditioned response (CR)

Theories of Human Development
Operant conditioning - B.F. Skinner (1904–1990)
Desired outcomes = more likely to repeat
Undesired outcomes = less likely to repeat
![Page 17: THEORIES IN HUMAN DEVELOPMENT. Theories… what are they good for? Understanding Generalization A basis for decision making Predicting future events](https://reader030.vdocument.in/reader030/viewer/2022032518/56649ccc5503460f9499551d/html5/thumbnails/17.jpg)
Positive and Negative Reinforcement
Positive reinforcement Behavior leads to addition of something
pleasant Negative reinforcement
Behavior is rewarded by the removal of something unpleasant
Negative reinforcement is not punishment “Negative” means removing something Remember that reinforcement increases
behavior
![Page 18: THEORIES IN HUMAN DEVELOPMENT. Theories… what are they good for? Understanding Generalization A basis for decision making Predicting future events](https://reader030.vdocument.in/reader030/viewer/2022032518/56649ccc5503460f9499551d/html5/thumbnails/18.jpg)
Positive and Negative Punishment
Punishment is an unpleasant consequence that leads to a decrease in behavior
Positive punishment Addition of something unpleasant that
decreases behavior Negative punishment
Removal of something pleasant that decreases behavior

Theories of Human DevelopmentSocial Learning Theory - Albert Bandura
(b. 1925) An extension of behaviorism that
emphasizes the influence that other people have over a person’s behavior.
Modeling- people learn by observing other people and then copying them.
Self-efficacy- (how effective people think they are when it comes to changing themselves or altering their social context.

Theories of Human DevelopmentCognitive Theory Thoughts and expectations profoundly
affect action. Focuses on changes in how people think
over time. Jean Piaget (1896–1980)

1.Sensorimotor Stage 2.Preoperational Stage3.Concrete Operational Stage4.Formal Operational Stage

Theories of Human Development Assimilation, in which new experiences
are interpreted to fit into, or assimilate with, old ideas
Accommodation, in which old ideas are restructured to include, or accommodate, new experiences
![Page 24: THEORIES IN HUMAN DEVELOPMENT. Theories… what are they good for? Understanding Generalization A basis for decision making Predicting future events](https://reader030.vdocument.in/reader030/viewer/2022032518/56649ccc5503460f9499551d/html5/thumbnails/24.jpg)
Theories of Human DevelopmentSystems Theory
Change in one part of a person, family, or society affects every aspect of development
Ecological systems approach- Urie Bronfenbrenner (1917–2005)
The person should be considered in all the contexts and interactions that constitute a life.
![Page 25: THEORIES IN HUMAN DEVELOPMENT. Theories… what are they good for? Understanding Generalization A basis for decision making Predicting future events](https://reader030.vdocument.in/reader030/viewer/2022032518/56649ccc5503460f9499551d/html5/thumbnails/25.jpg)
Theories of Human Development
Five Components of Bronfenbrenner’s System
microsystems (elements of the person’s immediate surroundings, such as family and peer group)
exosystems (local institutions such as school and church)
macrosystems (the larger social setting, including cultural values, economic policies, and political processes)
![Page 26: THEORIES IN HUMAN DEVELOPMENT. Theories… what are they good for? Understanding Generalization A basis for decision making Predicting future events](https://reader030.vdocument.in/reader030/viewer/2022032518/56649ccc5503460f9499551d/html5/thumbnails/26.jpg)
Theories of Human Development
chronosystem (literally, “time system”), which affects the other three systems
mesosystem, consisting of the connections among the other systems

Bioecological TheoryUrie Bronfenbrenner
Explains development in terms of relationships between people and their environments
Contexts Macrosystem Exosystem Microsystem Mesosystem Biological Context
