Light Adaptation – Process in which the eye becomes less sensitive to light in High Illumination. Dark Adaptation – The process in which the eye becomes more sensitive to light in low illumination. When you want to see an object in the dark, look slightly above or below where it should be to find it easier. Rods – Play a key role in Night Vision and Peripheral Vision.ġ. Fovea – Tiny spot in the center of the Retina that contains only Cones visual clarity is best here. Cones – Play a key role in Daylight Vision and Color Vision. Optic Disk – A hole in the Retina where the Optic Nerve Fibers exit the eye. The Retina is a part of the Central Nervous System. Retina – Neural Tissue lining the inside back surface of the eye it absorbs light, processes images, and sends visual information to the brain.ġ. Iris – Regulates the amount of Light entering the Pupil by controlling the size of the Pupil.

Pupil – The opening into the center of the Iris that permits light to pass into the rear chamber of the eye. Farsightedness – Distant objects are seen clearly, but close objects appear blurry.

Nearsightedness – Caused by Retina, Close objects are seen clearly, but distant objects appear blurry. Lens – Transparent eye Structure that focuses the light rays falling on the Retina. Two Purposes: Channel light to the Neural Tissue that receives it (Retina). Wavelength – Affects perception of Color (Distance between Peaks). Amplitude – Affects perception of brightness (Height). Light – Form of Electromagnetic Radiation that travels as a wave at the Speed of Light. Process that keeps people tuned into the changes rather than constants in Sensory Input. You jump in Cold Water it is very cold at first, But You Get Used to It. Sensory Adaptation – The Gradual Decline in Sensitivity to prolonged Stimulation.John Krosnick – Experimented and found that “Subliminal stimulation generally produces weak effects. Such as Subliminal Messages in movies, advertisements, etc.

Subliminal Perception – The registration of Sensory Input without conscious awareness.

Noise – Background distractions that lower the chance of detection of a Stimulus.

Signal-Detection Theory – The detection of stimuli involves Decision Processes, along as Sensory Processes, which are both influenced by a variety of factors besides Stimulus Intensity.

Weber’s Fraction – The Fractions that apply to different Sensory Inputs until a Difference is noted. Weber’s Law – The size of a Just Noticeable Difference is a constant proportion of the size of the initial Stimulus.ġ. Just Noticeable Difference (JND) – The smallest difference in stimulus intensity that a specific sense can detect. The Absolute Threshold is the Stimulus Intensity detected 50% of the time. As Stimulus Intensity Increases, the Subject’s probability to responding to Stimuli Gradually increases. Absolute Threshold – Minimum Stimulus Intensity that an Organism can detect. Question: For any Given Sense, what is the weakest detectable Stimulus? Wilhelm Wundt based lots of research upon Fechner. Psychophysics Psychologists in 1860’s at University of Leipzig.

Psychophysics - Study of how physical stimuli are translated into Psychological Experience.

Perception – the Selection, Organization, and interpretation of Sensory Input.

Sensation – The Stimulation of Sense Organs.
