Study Notes
Sensation & Perception: Key Concepts
- Sensory activation is strongest when a stimulus is initially detected, followed by sensory adaptation to conserve energy and attentional resources.
- Psychophysics, pioneered by Gustav Fechner in 1860, is the study of how we perceive sensory stimuli based on their physical characteristics.
- Absolute threshold refers to the lowest level of a stimulus that can be detected when no other similar stimuli are present, such as a single candle 48 kilometers away or 50 odorant molecules.
- Just Noticeable Difference (JND) represents the smallest amount of stimulus change that can be detected, following Weber's Law which states that the stronger the stimulus, the greater change needed to detect.
- Signal detection theory, introduced by Green & Swets in 1966, explains how stimuli are detected under uncertain conditions, with the signal-to-noise ratio affecting detection.
- Phosphenes, vivid sense of light caused by pressure on the eye's receptor cells, are examples of cross-modal senses.
- The McGurk effect illustrates the integration of visual and auditory information, while the rubber-hand illusion demonstrates the interaction between touch and sight to create false experiences.
- Our brains do not rely solely on current sensory input but also consider past information and engage in parallel processing to attend to multiple senses at once.
- Top-Down Processing involves analyzing whole stimuli and then processing smaller parts, while Perceptual constancy allows us to perceive stimuli consistently across varied conditions.
- Attention plays a crucial role in selective attention, as demonstrated by the Cocktail Party Effect and change-blindness.
- The visual system involves the perception of light, visible light wavelengths, and the reflection and absorption of light by objects.
- The structure of the eye, including the sclera, iris, pupil, cornea, and lens, affects the way light is focused onto the retina for visual perception.
