Study Notes

Scientific Explanation

A theory is a set of related statements explaining occurrences.
The fewer statements and more occurrences a theory explains, the better the theory.
A theory's accuracy doesn't guarantee its correctness, as some events may remain unexplained.
Theories in psychology organize data systematically, and generate predictions for situations lacking data.
Better theories offer more precise predictions.

Ringelmann (1913) observed reduced individual effort in groups.
Groups of two, three, and eight exhibited progressively lower effort compared to individual performance.
Social loafing is a phenomenon where people exert less effort in groups than alone.
This reduced effort stems from diffused responsibility in group settings.

Methodology of Psychological Research

Psychological research utilizes controlled experiments and observations to understand phenomena.
Experiments involve developing hypotheses, establishing testing conditions, gathering data, and analyzing/interpreting findings.
Experiments produce a deeper understanding than simple observation and reflection.

Curiosity and Skepticism

Scientists are driven by curiosity to understand how/why things work.
Skepticism is a crucial component of scientific reasoning, recognizing that no certainty exists in scientific knowledge.
Skepticism demands rigorous scrutiny of knowledge claims and conclusions.

Sources of Knowledge & The Scientific Method

The scientific method is a valid approach for acquiring knowledge about the world.
The scientific method prioritizes empirical observations, organizing concepts that predict future observations.
The scientific method contrasts with other ways of establishing beliefs.
The scientific method relies on experience.
This experience is based on the assumption that events have identifiable causes, discoverable through controlled observation (determinism).
Scientific methods emphasize empirical observation and the validation of theories.

Induction and Deduction

Induction: Reasoning from particular data to a general theory.
Deduction: Reasoning from a general theory to particular predictions.
In induction, data suggests organizing principles (theories).
In deduction, theories predict future observations (data).
Modern science combines these approaches.
Scientific observations can be limited or influenced by their context.
Theories derived from observations are tentative.

Falsifiability

Theories are based on potential falsification, meaning they can be proven incorrect by evidence.
Support for a theory is not conclusive proof, but rather increased confidence.
A good theory can be tested and potentially disproven; a well-tested idea withstands scrutiny.

Evaluating Theories

Scientists aim to understand which of several theories is best suited for our current understanding.
Four criteria for assessing theories:
- Parsimony: The theory is simple and economical in its explanations.
- Precision: The theory's predictions are clearly defined and measurable.
- Testability: The theory can be tested through experiments.
- Goodness of fit: The theory's predictions align with observed data.

Intervening Variables

Intervening variables connect independent variables (manipulated) to dependent variables (observed).
They explain how independent variables affect dependent variables.
Mediating variables explain indirect relationships.
Intervening variables provide a flexible, efficient way to link multiple factors.

Basic and Applied Research

Basic research aims to broaden knowledge and understanding.
Applied research aims at solving practical problems.
Basic research provides a foundation for applied research.
The quality of research (basic or applied) is more important than the category.

Research Techniques: Observation and Correlation

Observation is a method used in psychological research.
Correlation is a statistical method used in psychological research.
