Study Notes
Frequency Theory and Pitch Perception
- Frequency theory links pitch perception to the speed of basilar membrane vibrations.
- Higher vibration speeds correlate with higher pitches perceived by the brain.
Volley Principle
- The volley principle explains pitch perception for frequencies around 4000 Hz.
- Auditory neurons fire in a coordinated pattern, alternating the sequence of firings among hair cells.
Sensation of Smell
- Olfaction is the technical term for the sensation of smell.
Somesthetic Senses
- Somesthetic senses encompass skin senses, kinesthetic sense, and vestibular senses.
- They contribute to the overall awareness of bodily sensations.
Skin Senses
- Skin senses include touch, pressure, temperature, and pain sensations.
- These senses are essential for tactile interactions with the environment.
Kinesthetic Sense
- Kinesthetic sense provides awareness of body part positioning in relation to one another and the ground.
- It plays a crucial role in movement and coordination.
Vestibular Senses
- Vestibular senses help maintain awareness of balance, position, and movement in relation to gravity.
- They are vital for spatial orientation and navigating within the environment.
Sensory Conflict Theory
- Sensory conflict theory explains motion sickness as a mismatch between visual and vestibular information.
- This conflict can lead to symptoms such as dizziness and nausea.
Cocktail Party Effect
- The cocktail party effect allows individuals to focus attention on one stimulus while filtering out numerous competing stimuli.
- It exemplifies selective attention in social settings.
Size Constancy
- Size constancy is the perception that an object maintains a constant size despite changes in distance from the observer.
- This perceptual phenomenon helps with object recognition and spatial reasoning.
Shape Constancy
- Shape constancy reflects the ability to perceive an object's shape as uniform, irrespective of its angle or perspective.
- This aids in recognizing objects even when they appear distorted.
Brightness Constancy
- Brightness constancy allows for the perception of an object's brightness as stable, despite varying light conditions.
- This compensatory mechanism enhances visual consistency across different lighting environments.
Figure-Ground Perception
- Figure-ground perception is the tendency to distinguish objects (figures) from their backgrounds.
- It is fundamental for interpreting visual scenes.
Reversible Figures
- Reversible figures are visual illusions where the figure and background can be swapped in perception.
- These demonstrate the complexity of visual processing.
Proximity in Perception
- Proximity, a Gestalt principle, influences perception by grouping nearby objects as related.
- This principle relies on the physical closeness of items to infer connection or singular categorization.
