Study Notes
Conceptual Knowledge
- Concept: a mental representation of a class or individual, providing meaning.
- Concepts are crucial for recognizing objects, events, and making inferences about their properties.
- Categorization: grouping objects or entities based on shared characteristics defined by a concept.
- Categories encompass all possible examples of a concept, including common and non-common features.
- Categorization process groups items into categories.
Categorization Theories
- Definitional theories: classifying items based on a set of defining features.
- Necessary features: All members must share the defining features.
- Sufficient features: Any member with all the defining features belongs to the category.
- Limitations of definitional theories: defining features don't always exist for all categories.
- Family resemblance (Wittgenstein, 1953): Members of a category resemble each other in various ways, there is no single set of features shared by all.
- Prototype theories: comparing objects to a prototype representing the category.
- Prototype: a summary or average representation of category members.
- Typicality effect: typical category members are better examples than non-prototypical ones.
- Exemplar theories: categories are represented by individual exemplars (specific examples).
- Categorization is based on similarity to other exemplars encountered.
Connections Between Prototypicality and Behavior
- Mervis and coworkers (1976) and Smith and coworkers (1974): prototypical objects are named first.
Semantic Network Models
- Cognitive economy: shared properties are stored at higher-level nodes rather than at lower-level nodes.
- Predictions made according to the distance traveled through the network, measured in terms of links between concepts.
Criticisms of Semantic Network Models
- Unable to explain typicality effects, cognitive economy and the way that concepts are organized.
Connectionist Network Models
- Information is represented through patterns of activation across interconnected nodes.
- Concepts are distributed, not localized; patterns of activity in nodes provide the representation.
- Connection weights determine how signals from one node influence those on the next.
- Error signals adjust connection weights through backpropagation.
Representation of Concepts in the Brain
- Sensory-functional hypothesis: proposes different brain areas for sensory and functional features of concepts.
The Multiple-Factor Approach
- Concepts are influenced beyond two factors (sensory and function) by other factors including interactions, relationships and how people use or categorize them as well as their context.
Semantic Category Approach
- Proposes there are specific neural circuits for specific categories, not just divided areas.
Embodied Approach
- Knowledge of concepts based on past experiences.
- Reactivation of sensory and motor processes that occur when interacting with the object.
Hub and Spoke Model of Semantic Knowledge
- Based on the observation that areas of the brain associated with functions are connected to the ATL which integrates or stores the information.
- The ATL acts as a hub connecting different brain areas.
- Damage to areas in the brain connected to the ATL can cause deficits in the tasks related to that area.
Problem Solving and Creativity
- Alternative Uses Task: to measure divergent thinking, coming up with a large number of potential ideas.
- Problem solving as a "search" for a way to reach a goal.
- Gestalt approach to problem solving: representing a problem in the mind, restructuring the representation, and using insightful solutions (or AHA moment).
- Functional fixedness: focusing on familiar functions of objects, hindering problem solving.
- Mental set: preconceived notions about how to approach a problem, which is determined by past experiences that may hinder problem solving.
- Analogical problem solving: using a similar problem "source" to find a solution to a new problem "target."
Deductive Reasoning
- Syllogism: a logical argument with two premises (premises) and a conclusion, which is derived from the premises.
- Validity: deductive argument where the conclusion follows from the premises.
- Truth: conclusion is valid and consistent with the real world.
- Mental Model theory (Johnson-Laird, 1999): people create mental representations of the problem situation.
Emotion and Decision Making
- Incidental emotions: emotions encountered earlier that can impact decision making.
- Risk aversion: anxious people avoid choices with high potential for negative consequences. Decision-making influenced by
- Situational factors
- How choices are presented (status quo bias, framing, anchoring)
- Present state of mind
Perception
- Bottom-up processing: stimulus-driven processing, starts with sensory input and works towards more complex representations.
- Top-down processing: knowledge-driven processing, interpretations impacted by prior knowledge, beliefs and expectations.
- Gestalt principles of organization: innate rules that organize sensory inputs into meaningful patterns.
- Regularities of the environment: aspects are frequent in an environment (e.g., light coming from above).
- Visual pathways: routes that visual information takes to go from the eye to the brain, which allows for higher-level analysis
- Bayesian Inference: based on initial beliefs and the likelihood of different outcomes, and the way we update these probabilities based on new evidence encountered.
