Sensory disabilities are studied in: (a) Observation Method (b) Experimental Method (c) Development Method (d) Psycho-physical Method ✅ Correct Option: (d) Psycho-physical Method Explanation: The psycho-physical method studies the relationship between physical stimuli and the resulting sensations or perceptions in humans. It is particularly useful in understanding sensory disabilities, such as visual or auditory impairments. This method investigates how a person perceives stimuli such as light, sound, and touch and how these perceptions affect behavior and learning. For example, in studying children with hearing impairment, the psycho-physical method measures the minimum sound intensity required for hearing and examines how this sensory limitation affects cognitive development. It is widely used in educational psychology and special education to design interventions and teaching strategies tailored to students with sensory deficits. Other methods like observation or experimental methods are general tools in psychology but do not specifically focus on the link between physical stimuli and perception, which is the core of the psycho-physical approach. The development method studies growth patterns over time but does not measure sensory thresholds. 10 PPSC-Relevant Facts: 1. Psycho-physical method = relationship between stimulus and perception 2.
