Cognitive Learning01:21

Cognitive Learning

1.6K
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...

Theorems of Pappus and Guldinus: Problem Solving

1.2K
Pappus and Guldinus's theorems are powerful mathematical principles that are used for finding the surface area and volume of composite shapes. For example, consider a cylindrical storage tank with a conical top. Finding the surface area or volume can be challenging for such complex shapes. These theorems are particularly useful in calculating the volume and surface area of such systems. Here, the cylindrical storage tank with a conical top can be broken down into two simple shapes: a...

Problem-Solving

680
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:

Castigliano's Theorem: Problem Solving01:14

Castigliano's Theorem: Problem Solving

1.6K
The deflection of a simply supported beam that carries a central point load can be analyzed using structural mechanics principles, particularly by applying Castigliano's theorem. This theorem relates the displacement at the load application point to the partial derivatives of the strain energy in the structure. The simply supported beam with a point load at its center has symmetric reaction forces at the supports, each bearing half of the load. The bending moment at any point along the beam is...

Collisions in Multiple Dimensions: Problem Solving

4.5K
In multiple dimensions, the conservation of momentum applies in each direction independently. Hence, to solve collisions in multiple dimensions, we should write down the momentum conservation in each direction separately. To help understand collisions in multiple dimensions, consider an example.
A small car of mass 1,200 kg traveling east at 60 km/h collides at an intersection with a truck of mass 3,000 kg traveling due north at 40 km/h. The two vehicles are locked together. What is the...

Statically Indeterminate Problem Solving01:16

Statically Indeterminate Problem Solving

948
Statically indeterminate problems are those where statics alone can not determine the internal forces or reactions. Consider a structure comprising two cylindrical rods made of steel and brass. These rods are joined at point B and restrained by rigid supports at points A and C. Now, the reactions at points A and C and the deflection at point B are to be determined. This rod structure is classified as statically indeterminate as the structure has more supports than are necessary for maintaining...

Area of Science:

  • Cognitive psychology
  • Problem-solving research

Background:

  • Insightful thinking is crucial for problem-solving.
  • Existing models often focus on either search or representational change independently.

Purpose of the Study:

  • To investigate the interplay between problem space search and representational change in insight problem solving.
  • To test the effectiveness of combined hints on solution rates for Katona's five-square problem.

Main Methods:

  • Developed a cognitive model integrating problem space search and representational change.
  • Conducted an experiment with 168 participants using Katona's five-square problem.
  • Introduced independent and combined hints targeting search space and representational change.

Main Results:

  • Independent hints for search space or representational change had minimal impact on solution rates.
  • Providing both types of hints significantly increased the success rate in solving the problem.
  • Demonstrated that both search space constraints and representational change are critical for insight.

Conclusions:

  • Insight problem solving is facilitated by the dynamic interplay between exploring the problem space and altering mental representations.
  • Effective problem-solving strategies require addressing both the initial search limitations and the representational barriers.
  • The cognitive model provides a framework for understanding how to overcome impasses in complex problem-solving tasks.
