Study Notes
Sensory Perception Concepts
- Weber's Law explains how the noticeable change in stimulation varies with context, impacting sensory detection.
- Afterimages are visual artifacts experienced after looking away from bright lights, showing persistence in sensation.
- Vertigo is characterized by a spinning sensation, indicating disturbances in balance or spatial orientation.
Visual and Sensory Awareness
- The visible spectrum is the segment of the electromagnetic spectrum that humans can perceive visually.
- Somatosensation refers to the perception of touch and bodily sensations, as illustrated by the experience of stroking someone's hand.
- Perception is the interpretation of sensory information, while sensation is the detection of that information by sensory receptors.
Light and Visual Processing
- Amplitude does not refer to the lowest point of a wave; it signifies wave intensity or height.
- Inattentional blindness occurs when individuals fail to notice visible stimuli due to focused attention on specific elements.
- The optic nerve is crucial for transmitting visual signals from the retina to the brain for processing.
Chemical Senses and Communication
- Pheromones serve as chemical signals that communicate information between individuals in a species.
- The optic chiasm coordinates visual input from both eyes, facilitating binocular vision.
Chemical Senses Functionality
- Olfaction (smell) and gustation (taste) are termed chemical senses because they rely on receptors that detect airborne and food-related molecules.
Pain Sensation and Psychological Principles
- Nociception provides crucial information regarding pain, as experienced when Felicia smacks her thumb with a hammer.
- Gestalt psychology emphasizes the significance of holistic perceptions, including concepts like figure-ground relationship and principles of closure.
Subliminal Messaging
- Subliminal messages, such as "Drink Cola," operate below the absolute threshold for conscious awareness, indicating their subtle influence.
Other Sensory Mechanisms
- Fovea misrepresents a continuation of visual sensation; it specifically refers to the area of sharpest vision in the retina.
- Top-down processing allows interpretation of sensory input, shaped by prior knowledge and experiences.
- Inattentional sublimation is not a term; the correct term is inattentional blindness for missing visible stimuli due to focused attention.
- Kinesthesia refers to awareness of body movement and position, as demonstrated by Felix riding a bicycle.
- Transduction is the process where ears convert sound waves into neural messages, enabling auditory perception in the brain.
