Study Notes
Natural Concepts
- Natural concepts arise from everyday experiences and perceptions, allowing individuals to categorize objects or ideas based on common characteristics or features.
Reasoning Types
- Deductive reasoning involves drawing conclusions from general principles to specific instances, often leading to logically sound results if the premises are true.
Prototypes
- A prototype is a mental representation or best example of a category, embodying the most typical features of the items belonging to that category.
Algorithms vs. Heuristics
- Algorithms are step-by-step procedures or formulas guaranteed to find a solution, while heuristics are mental shortcuts that often simplify decision-making but do not guarantee a correct solution.
Regression Analysis Function
- The main function of regression analysis is to model the relationship between a dependent variable and one or more independent variables, helping to predict outcomes and identify trends.
Pearson's r Squared (R2)
- R2 measures the proportion of variance in the dependent variable that can be explained by the independent variable(s) in a regression analysis, indicating the goodness of fit for the model.
Cook's Distance
- Cook's Distance assesses the influence of individual data points on the fitted regression model, identifying points that significantly impact model estimates or predictions.
Variance Inflation Factor (VIF)
- VIF measures the extent of multicollinearity in regression analysis; an acceptable threshold is generally a VIF less than 10, with Tolerance (1/VIF) ideally above 0.1.
Cognition Process
- The cognition process involves mental activities related to thinking, reasoning, and problem-solving, guiding behavior and decision-making.
Functional Fixedness
- Functional fixedness refers to the cognitive bias that limits a person to use an object only in its traditional way, hindering creativity in problem-solving.
Syntax
- Syntax pertains to the rules and principles that govern the structure of sentences in a language, defining how words combine to form meaningful phrases.
Insight in Problem-Solving
- Insight is a problem-solving strategy characterized by the sudden realization or understanding of a solution, often described as "eureka" moments.
Phonology
- Phonology studies the sound systems of languages and how these sounds function and interact within language contexts.
Mental Set
- A mental set is the tendency to approach problems using strategies that have previously been successful, potentially limiting innovative solutions.
