Study Notes

Scientific Explanation

There are different sources of knowledge, including: fixation of belief
Theories in psychology play a critical role by:
- Organizing data: Providing structure and order to experimental results.
- Generating predictions: Allowing scientists to make forecasts in unobserved situations.
The accuracy and precision of predictions are crucial in evaluating the quality of a theory.
Theories are used for different functions, including:
- Organization: Providing a framework for arranging collected data.
- Generation of predictions: Extending the application of the theory to novel scenarios.
Social loafing: A phenomenon where individuals exert less effort in a group task, which is linked to the diffusion of responsibility principle.
Theory of diffusion of responsibility: Explains why larger groups often lead to reduced individual effort.

Generalizations and Hypotheses

Generalizations can be derived from theory or experience.
Common-sense hypotheses: Derived inductively from experience or casual observations.
Theory-based hypotheses: Derived deductively from theoretical frameworks.
Example: The generalization about older drivers being more accident-prone could be derived from experience or from theories of attention, perception, and decision-making.

Source of Generalizations

Generalizations can originate from:
- Experience: Direct or indirect observations.
- Theory: Existing scientific frameworks.
- Common-sense: Observations and intuitions based on everyday life.

Scientific Research

Scientific research often involves testing hypotheses derived from both common-sense observations and established theories.
Evaluating the validity of common-sense hypotheses has become increasingly recognized as valuable in experimental psychology.
