Young children were shown objects and asked to rate their similarity. They also were asked about the actions of these objects, and they used rules about nature to answer, even if the object looked less similar.

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.
