2.2 Thinking, Problem-Solving, Judgments, and Decision-Making

Verified for the 2025 AP Psychology (2025) exam4 min readLast Updated on March 5, 2025

Thinking, problem-solving, judgments, and decision-making are key cognitive processes that shape our understanding of the world. These mental activities involve concepts, schemas, and various strategies for processing information and finding solutions to challenges.

Our brains use shortcuts like heuristics and algorithms to navigate complex situations. However, these methods can lead to biases and errors in judgment. Understanding these processes helps us make better decisions and think more creatively.

Psychological concepts in cognitive processes

Concepts and prototypes

Concepts are the fundamental building blocks that allow us to categorize and make sense of the world around us. They help us organize information efficiently and recognize patterns in our environment.

Key aspects of concepts include:

  • Mental representations that define categories of objects, ideas, or experiences
  • Shared features that help us identify members of a category
  • Flexibility to accommodate variations within categories

Prototypes serve as the ideal or most typical examples of concepts:

  • They represent the clearest examples of category membership
  • Help us quickly identify and classify new information
  • Influence our expectations and judgments about category members

We compare new examples to prototypes and the more an item matches, the more likely we'll include it in that category.

Schema formation and modification

Schemas are complex mental frameworks that organize our knowledge and guide our understanding of new experiences. These cognitive structures evolve through two main processes:

Assimilation = Incorporating new information into existing schemas:

  • Adding details to current understanding
  • Reinforcing established patterns
  • Building upon previous knowledge

Accomodation = When we encounter information that doesn't fit our existing schemas

  • Modifying current schemas to incorporate new information
  • Creating new mental categories
  • Adjusting our understanding to match reality

Algorithms for problem-solving

Systematic problem-solving approaches help us find solutions through careful analysis and structured thinking.

Algorithms provide step-by-step procedures that:

  • Guarantee a solution if followed correctly
  • Work well for well-defined problems
  • May require significant time and resources

The effectiveness of algorithms depends on:

  • Problem complexity
  • Available resources
  • Time constraints
  • Required accuracy

Heuristics and judgment errors

Mental shortcuts help us make quick decisions but can lead to systematic errors in judgment. These cognitive tools evolved to help us process information efficiently, but they don't always lead to optimal outcomes.

Common heuristics include:

  • Availability: judging likelihood based on easily remembered examples
  • Representativeness: making judgments based on similarity to prototypes
  • Anchoring: relying too heavily on initial information

These shortcuts can result in various biases:

  • Overestimating the frequency of memorable events
  • Stereotyping based on limited information
  • Making poor probability judgments

Influences on decision-making

Our decisions are shaped by various mental and environmental factors. These influences can work both consciously and unconsciously, affecting our choices in big ways.

Key influences include:

  • Mental set and functional fixedness
  • Priming effects from recent experiences
  • Framing of information and choices
  • Environmental or contextual factors

Decision making can be influenced by:

  • Mental set or past experiences that were successful
  • Circumstances surrounding a decision (time pressure, emotional state, social influences, available info)
    • Priming effects of recent experiences
    • Framing of information and choices

Cognitive biases in decisions

Systematic patterns of deviation from rational judgment affect our decision-making in predictable ways. Understanding these biases helps us recognize and potentially overcome them.

Common cognitive biases include:

  • Confirmation bias: seeking information that supports existing beliefs
  • Anchoring bias: over-relying on first pieces of information
  • Hindsight bias: overestimating ability to predict past events
  • Gambler's fallacy: Misunderstanding random events (like thinking you're "due" for a win)
  • Sunk-cost fallacy: Continuing to invest in something just because we've already put time or money into it
  • Overconfidence bias: Overestimating how good we are at something

These biases can impact financial decisions, risk assessment, personal relationships, and professional judgments.

Executive functions for behavior

Executive functions are higher-order cognitive processes that help us regulate behavior and achieve goals. These mental skills develop throughout childhood and continue to mature into early adulthood.

Core executive functions include:

  • Working memory (holding and manipulating info in our minds)
  • Cognitive flexibility (adapting to new situations
  • Inhibitory control (resisting impulses)

These processes support important abilities such as:

  • Planning and organization
  • Time management
  • Self-monitoring
  • Emotional regulation

Creativity and divergent thinking

Creativity involves generating novel and valuable ideas or solutions. This complex cognitive process draws on multiple mental abilities and can be enhanced through practice and technique.

The creative process often involves:

  1. Preparation: Gathering relevant info
  2. Incubation: Letting ideas develop in the background
  3. Illumination: Having the "aha" moment
  4. Verification: Testing and refining ideas

Things that can block creativity include:

  • Functional fixedness (getting stuck on one use for an object)
  • Self-censorship (criticizing our own ideas too harshly)
  • Fear of failure
  • Limited perspective
