Study Notes
Sensation
- Sensation is the process of detecting physical energy from the environment and converting it into neural signals.
- Perception is the process of selecting, organizing, and interpreting sensations.
Sensory Processing
- Transduction: Converting physical energy into neural signals.
- Different sensory organs transduce different forms of energy (light, sound, pressure, etc).
- Sensory Coding: Converting stimulus characteristics (like intensity and quality) into patterns of neural activity.
- Psychophysics: Systematic study of the relationship between the physical characteristics of stimuli and the sensations they produce in humans.
Transduction Examples
| Location of Sense Organ | Environmental Stimulus | Energy Transduced |
|---|---|---|
| Eye | Light | Radiant energy |
| Ear | Sound | Mechanical energy |
| Vestibular system | Tilt and rotation of head | Mechanical energy |
| Tongue | Taste | Recognition of molecular shape |
| Nose | Odor | Recognition of molecular shape |
| Skin, Internal Organs | Touch | Mechanical energy |
| Temperature | Thermal energy | |
| Vibration | Mechanical energy | |
| Muscle | Pain | Chemical reaction |
| Stretch | Mechanical energy |
Anatomical Coding
- Interpreting the location and type of sensory stimulus based on which incoming nerve fibers are active.
Psychophysics
- The systematic study of the relation between the physical characteristics of stimuli and the sensations they produce.
- How do we measure these sensations?
- A study of the relationship between physical characteristics of stimuli and psychological experience.
- Light-Brightness
- Sound-Volume
- Pressure-Weight
- Sugar-Sweet
Just Noticeable Difference (JND)
- The smallest difference between two similar stimuli that can be distinguished.
- Also called the difference threshold.
- The minimum difference between two stimuli required for detection 50% of the time.
Absolute Thresholds
- The minimum stimulation needed to detect a particular stimulus 50% of the time.
- Vision: A candle flame seen from 30 miles away on a clear, dark night.
- Audition (hearing): The tick of a watch at 20 feet.
- Olfaction (smell): One drop of perfume spread throughout a six-room apartment.
- Gustation (taste): One teaspoon of sugar in two gallons of water.
- Body senses: A bee's wing falling on your cheek from a height of about half an inch.
Weber's Law
- Two stimuli must differ by a constant minimum percentage (rather than a constant amount) to be perceived as different.
- Light: 8%
- Weight: 2%
- Tone: 3%
Subliminal Threshold
- When stimuli are below one's absolute threshold for conscious awareness.
Signal Detection Theory
- A theory predicting how and when we detect the presence of a faint stimulus (signal) amidst background stimulation (noise).
- Assesses how we make decisions under conditions of uncertainty.
- Hit: Signal present, response "yes."
- Miss: Signal present, response "no."
- False alarm: Signal absent, response "yes."
- Correct negative: Signal absent, response "no."
Bottom-up Processing
- Analysis of the stimulus begins with the sense receptors and works up to the level of the brain and mind.
- Starting with sensory information and building a perception.
Top-down Processing
- Information processing guided by higher-level mental processes as we construct perceptions.
- Drawing on our experience and expectations.
Making Sense of Complexity
- Sensory and perceptual processes work together to help us sort out complex images.
Sensing the World
- Senses are nature's gift that suit an organism's needs.
Sensory Adaptation
- Diminished sensitivity as a consequence of constant stimulation.
The Stimulus Input: Light Energy
- The visible spectrum of light is part of the electromagnetic spectrum.
- The human eye and bee's eye are sensitive to different parts of light spectrum.
Wavelength (Hue)
- Hue (color) is the dimension of color determined by the wavelength of the light.
- Short wavelength = high frequency (bluish colors, high-pitched sounds).
- Long wavelength = low frequency (reddish colors, low-pitched sounds).
- Different wavelengths of light result in different colors.
Intensity (Brightness)
- Intensity is the amount of energy in a wave determined by the amplitude.
- Related to perceived brightness.
- Great amplitude: bright colors, loud sounds.
- Small amplitude: dull colors, soft sounds.
- As intensity increases or decreases, colour looks more "washed out" or "darkened."
The Eye and Its Functions
- Detail on eye parts (cornea, iris, lens, retina, sclera).
- Nearsightedness: eye too long, image focused in front of fovea; Corrected by concave lens.
- Farsightedness: eye too short, image focused behind fovea; Corrected by convex lens.
Transduction of Light by Photoreceptors
- Photoreceptors (Rods and Cones) convert light energy into neural signals.
Photoreceptors
- Cones: 6 million; central retina; low sensitivity in dim light; color sensitive; detail sensitive
- Rods: 120 million; peripheral retina; high sensitivity in dim light; not color sensitive; not detail sensitive
Visual Information Processing
- Optic nerves connect to the thalamus, and the thalamus connects to the visual cortex.
- Processing of several aspects of the stimulus simultaneously (Parallel Processing)
- Dividing a visual scene into subdivisions such as color, depth, form, and movement.
Shape Detection
- Specific combinations of temporal lobe activity occur as people look at shoes, faces, chairs, and houses.
Eye Movements
- Vergence movements: Cooperative movements of the eyes.
- Saccadic movements: Rapid movements of the eyes used for scanning a visual scene.
- Pursuit movements: Movements made to keep a moving image on the foveas.
Colour Vision
| Perceptual Dimension | Physical Dimension | Physical Characteristics |
|---|---|---|
| Hue | Wavelength | Length of oscillation of light radiation |
| Brightness | Intensity | Amount of energy of light radiation |
| Saturation | Purity | Intensity of dominant wavelength relative to total radiant energy |
Colour Mixing
- Colour mixing by light and paint.
Colour Blindness
- Genetic disorder in which people are blind to green or red colours; supports Trichromatic Theory.
Opponent Colors
- Specific colour perception.
Defects in Colour Vision
- Protanopia: Red cones filled with green photopigment.
- Deuteranopia: Green cones filled with red photopigment.
- Tritanopia: Lack of blue cones.
