List - I (Theory)
p. Doctrine of specific nerve energies
q. Frequency theory
r. Purkinje effect
s. Law of Pragnanz
List - II (Explanation)
1. The basilar membrane vibrates as a whole to the frequency of the sound wave.
2. The sensation elicited by stimulus depends primarily on the nerve excited and secondarily on the stimuli.
3. Refers to the tendency to perceive the simplest and the most stable figure of all possible alternatives.
4. The illumination decreases owing to the shift from photopic cone vision to scotopic rod vision.
Exam Solution: Matching Psychological Theories
This solution provides a concise matching of theories from List-I with their explanations from List-II, focusing on key concepts in psychology and perception.
Matching List-I (Theory) with List-II (Explanation)
The question requires matching specific psychological theories with their correct explanations. The correct pairings are determined as follows:
p. Doctrine of Specific Nerve Energies
Explanation Match: 2. The doctrine states that the quality of a sensation (e.g., seeing, hearing) depends on the specific nerve pathway stimulated, not the stimulus itself. This aligns with the explanation: "The sensation elicited by stimulus depends primarily on the nerve excited and secondarily on the stimuli."
q. Frequency Theory
Explanation Match: 1. This theory of hearing posits that the frequency of nerve impulses matches the frequency of the sound wave. The explanation provided, "The basilar membrane vibrates as a whole to the frequency of the sound wave," describes a key aspect of how sound frequency is transduced and perceived, making it the most fitting match among the options.
r. Purkinje Effect
Explanation Match: 4. The Purkinje effect concerns how the perceived brightness of colors changes under different light conditions, specifically the shift from bright (photopic) to dim (scotopic) light. Explanation 4, "The illumination decreases owing to the shift from photopic cone vision to scotopic rod vision," describes this transition and its relation to vision types.
s. Law of Pragnanz
Explanation Match: 3. A core principle of Gestalt psychology, the Law of Pragnanz states our tendency to perceive the simplest, most stable, and most organized form possible from a collection of stimuli. This directly matches the explanation: "Refers to the tendency to perceive the simplest and the most stable figure of all possible alternatives."
Final Answer Code
Based on the matching above:
- p matches with 2
- q matches with 1
- r matches with 4
- s matches with 3
This corresponds to the code p-2, q-1, r-4, s-3.
