Which of the following psychological statements is most authentic and scientifically valid regarding Edwin Guthrie's 'Contiguity Theory of Learning', specifically concerning the concept of 'One-Trial Learning', the methods used for habit modification—namely the 'Fatigue Method', 'Threshold Method', and 'Incompatible Stimuli Method'—and their practical psychological implications for the extinction of undesirable student behavior, the logical control of stimulus-response (S-R) associations, and the scientific management of habit formation in classroom teaching?

Explanation of Guthrie's Contiguity Theory

Edwin Guthrie's Contiguity Theory of Learning emphasizes that when a stimulus and a response occur together in close temporal proximity, an association is established between them.

• One-Trial Learning: Guthrie argued that learning is complete on the very first pairing of stimulus and response; rewards or reinforcements are not strictly necessary for learning to occur.
• Methods of Habit Breaking: Guthrie proposed three classic methods to eliminate undesirable habits:
• Fatigue Method: Forcing the organism to repeat the undesired response until it becomes fatigued, preventing the response from occurring again.
• Threshold Method: Introducing the stimulus at a very weak intensity below the threshold that elicits the undesirable response, gradually increasing it over time.
• Incompatible Stimuli Method: Presenting the stimulus in a context where the undesired response cannot occur, thereby pairing the stimulus with a different, compatible response.

Therefore, Option (A) accurately and scientifically describes the core tenets of Guthrie's learning theory and habit modification techniques.
