Evaluation and Interactionist Approach

The second page delves into critical evaluations of reductionist approaches and introduces the interactionist perspective.

Definition: The diathesis-stress model represents an interactionist approach combining biological predisposition with environmental triggers.

Example: Mental health conditions like schizophrenia and depression are understood through both genetic factors and environmental influences.

Highlight: The limitation of reductionism lies in its potential oversimplification of complex behaviors by neglecting social contexts.

Quote: "The oversimplification of complex behaviour leads to loss of validity."

Understanding Holism and Reductionism in Psychology

The first page introduces fundamental concepts in psychological analysis, focusing on levels of explanation in psychology and contrasting approaches to understanding behavior.

Definition: Biological reductionism refers to analyzing behavior by breaking it down into its smallest biological components, such as neurons and neurotransmitters.

Example: In OCD cases, behavior can be analyzed at multiple levels:

• Social-cultural: Observable hand-washing behavior
• Psychological: Emotional relief from washing
• Physical: Motion sequences
• Neurochemical: Serotonin levels

Highlight: The scientific nature of reductionism allows for operationalized variables and reliable experimental procedures, enhancing psychology's credibility.

Vocabulary: Operationalized variables are precisely defined, measurable aspects of behavior used in psychological research.
