2. Information Processing Models: 2.1 Categorization and Schema Theories Flashcards
Types of Human memory
Cognitive psychologists describe various types of memory and thus different types of learning.

Cognitive Networks
Individual knowledge units in the network of structural conceptual knowledge: mental concepts, categories and schemas

Semantic Networks Models
(a) Concepts
The human semantic memory is organized as a network that includes: factual knowledge, integration rules and analytical problem solving patterns
Associative network: (which is composed of nodes and links)
- Nodes represent individual concepts (e.g. attributes, objects) and are linked
- through associations/ connections of different type and intensity
- hierarchical structure is assumed
Piecemeal- and Category-Based Information Processing
(b) Category
Definition: Categorization
Categorization:
- Evaluating whether a new stimulus is congruent or incongruent to existing schemas in mind
- Process runs automatically, without cognitive control

Exmple:
- Category-based processing
- Piecemeal-based processing
Category-based processing:
- General image is transferred on the product, e.g., your thoughts about hospitals, doctors. You transfer all this on the ad and the brand without much thinking.
- Or maybe, you look on whether the ad is typical for advertising and transfer your category knowledge of advertising on the ad.
Piecemeal-based processing:
- If a person perceives incongruence (and is also willing to use some cognitive effort), the person will use piecemeal-based processing: Read the ad carefully through, evaluate what the message is, e.g., realize it’s black humor, a sign of cultural knowledge … and whether she likes this.

Schema Theory
(c) Schema
Adaption
Assimilation:
- new stimuli will be integrated into existing category
- if necessary will be reinterpreted (existing schemas sufficient)
Accommodation:
- if a new stimulus does not fit into existing schemas (assimilation), they must be extended, or a new schema is established (accommodation)
- accommodation occurs when assimilation fails
Schema-Congruity-Effect
Congruity:
Information about a new stimulus is congruent with expectations for a stimulus category
- positive sense of familiarity (weak)
- this feeling spills over to the new stimulus
Moderate Incongruity:
The constellation is somewhat surprising.
- people perceive such stimuli as interesting
- an explanation for the incongruity can be found by increasing cognitive effort
- the stimulus can be included in an existing category (= assimilation)
- because the recipient has an experience of success, a positive emotion results
Strong Incongruity:
Strong mismatch between a new stimulus and expectations.
- the recipient can either assign the stimulus to an alternative schema, try to expand an existing schema or form a subschema (= accommodation)
- if he succeeds, he feels a strong positive emotion
- if he fails, a feeling of frustration and helplessness occurs;
