Schema Theory (3. 4) 1. Evaluate schema theory with reference to research studies 2. Describe schema theory as it applies to human behavior (SAQ)

What is schema theory? • One of the many theories about how we organize knowledge • Cognitive structure that provides the framework for organizing the world – People – Places – Events • Cognitive Schema
Schema based on previous experience Schema influences our perception and behavior NEW Schema
Mental processing (schemas) guide behavior • Mostly automatic – Processed with little attention • Bottom-up processing (information input) – Based on sensory system • Top-down processing (information is processed by the brain) – Pre-stored information in memory – Interpretation of stimuli • Output in the form of behavior – Shown in scientific research
Video on Gestalt Psychology • Read the Gestalt principles on the handout • Label each diagram with the appropriate Gestalt Principle • http: //www. youtube. com/watch? v=P 7 iqpe. QZ -Fk • http: //www. youtube. com/watch? v=vho. Sq. SH MIAc
Active Processors of information School See if you can add 30 pieces of information based on your schema of schools
Different terms for schemas • Scripts – Provide information about the sequence of events • Restaurant, dentist, class • Self-schemas – Information about ourselves – Strengths and weaknesses • How we feel about them • Social schemas – Information about groups of people • Remember Units of knowledge (concepts) are organized into schemas
On a blank piece of Paper 10 items per schema
Gender Schema Societies beliefs about the traits of females and males GENDER SCHEMA Influences processing of social information Influences self-esteem (only behavior or attitudes consistent with gender schema are acceptable)
Activity: • Pick FIVE animate movies and describe the gender schema that is being created in children • Example: – Tiana and Prince Navene in “The Princess and The Frog • Women are hard working and men are lazy and only care about money and good looks
Darley and Gross, 1983 • Aim: investigate whether people’s memory for a story is affected by previous knowledge (schema) • Procedure “rich girls, poor girl” and success (reference 3. 1 and 3. 2)
Brewer and Treyens, 1981 • AIM: investigate whether people’s memory for objects in a room (an office) is influenced by existing schemas about the office • Method: experiment • Procedure: wait in office with traditional and untraditional office items • Results – Most recalled the schematic objects and very unusual objects – Some reported items that were expected to be in an office • Evaluation – Ecological validity – Deception was necessary, participants were debriefed and there was not harm – Difficult to generalize results college students
How does schema impact memory? • People remember the “gist” – Not exact wording • Reconstructive memory – Filling in the gaps with previous knowledge (schema) • Aschematic information – Ignore information that is not in-line with schema • Leads to bias and stereotype confirmation • Tend to focus on information that confirms schema – Confirmation bias
Evaluation of Schemas Theory • Strengths – Useful in explaining many cognitive processes • Perception, memory, reasoning – Helps us understand reconstructive memory • Eyewitness testimony • Gender identity • Cultural differences • Limitations – Schema theory is too vague – How are they acquired in the first place? – Focuses too much on inaccuracies of memory • Most memory tasks are relatively accurate
Research Organization • Darley and Gross, 1983 • Bartlett 1932 – Culture specific scripts • Brewer and Treyens, 1981 • Gauld and Stephensn, 1967 – Follow-up to Bartlett • Bransford and Johnson, 1972 – Focused on process/stages – Bartlett focused on retrieval • Bower et al. 1979 – Script schemas • Macrae et al. , 1994 – Stereotypical knowledge • Turnbull, 1961 – Schemas are adaptable
• QUIZ TOMORROW: SAQ • You will be given a research summary • You will be required to – Summarize theoretical foundation (Why did behavior change in the research? ) – Summarize a follow-up research that supports OR contradicts the research provided » Who, when, aim, method, brief procedure, results, implications as they relate to the previous research and theory
• Small Group activity” – Go through all the research in your notes and discuss how you will summarize theory and which research will you use as a follow-up Theory Research Schema impacts Bartlett, 1932 memory & culture impacts schema…we use culture for our script, self and social schemas Follow-up Turnbull 1961: Schemas are adaptable. Cultural and environmental experience may limit schemas but experience changes schemas
