Problem-Solving01:29

Problem-Solving

205
Effective problem-solving consists of two steps: 1. identifying the problem and 2. selecting the appropriate problem-solving strategy (i.e., a plan of action used to find a solution). Humans use four problem-solving strategies:

Cognitive Learning01:21

Cognitive Learning

459
Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
Tolman introduced the idea that behavior is influenced by...

Normal and Tangetial Components: Problem Solving

209
Consider a man with a mass of 70 kg seated in a chair connected to a pin support through a member BC. If the man maintains an upright position, the task is to determine the horizontal and vertical reactions of the chair on the man when the member makes a 45° angle with the horizontal. At this moment, the man has a speed of 5 m/s, increasing at a rate of 1 m/s².

Heuristics01:21

Heuristics

114
Heuristics are problem-solving strategies that use mental shortcuts to simplify decision-making. Unlike algorithms, which must be followed precisely to achieve a correct result, heuristics offer a general problem-solving framework. They save time and energy but can sometimes lead to less rational decisions.
People often rely on heuristics when faced with an overload of information, limited time, low importance of the decision, limited information, or when a heuristic readily comes to mind. For...

Revisionist Views of Adolescent and Adult Cognition01:24

Revisionist Views of Adolescent and Adult Cognition

67
A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are...

Cognitivism

1.5K
Cognitive psychology emerged as a significant field in the mid-20th century. It focused on understanding humans' internal mental processes. This approach emphasizes how people perceive, remember, think, and solve problems—elements critical to human cognition.
Previously dominated by behaviorism, which prioritized observable behaviors and largely ignored mental processes, psychology transformed in the 1950s. Cognitive psychologists argue that understanding how we think and process...

Area of Science:

  • Cognitive Psychology
  • Neuroscience
  • Computational Statistics

Background:

  • Insight problems often involve overcoming initial incorrect mental representations.
  • The suddenness of representational change during insight problem solving remains debated.
  • Existing measures often rely on subjective reports, limiting objective analysis.

Purpose of the Study:

  • To investigate objective methods for detecting representational change in insight problem solving.
  • To compare the efficacy of classical versus nonlinear statistical models in analyzing insight processes.
  • To examine the impact of explicit hints on the dynamics of problem restructuring.

Main Methods:

  • Utilizing eye-tracking data combined with advanced analytical techniques.
  • Dividing problem-solving into ten relative temporal phases for detailed analysis.
  • Applying generalized additive (mixed) models (GAMs) and change point analysis.

Main Results:

  • Classical statistical procedures like ANOVA failed to identify abrupt representational changes.
  • Nonlinear statistical models (GAMs, change point analysis) successfully detected sudden shifts in problem representation.
  • Explicit hints altered the restructuring dynamics, affecting participants' focus.

Conclusions:

  • Sudden representational change is characteristic of insight problems.
  • Sophisticated nonlinear statistical approaches are crucial for objectively analyzing insight processes.
  • Hints influence problem-solving dynamics by reorienting cognitive focus.
