Psychical stimuli and the sensations produced from them. signal detection theory - Signal detection theory is a method of differentiating a person's ability to discriminate the presence and absence of a stimulus (or different stimulus intensities) from the criterion the person uses to make responses to those stimuli. Ex. hearing a siren while on busy street, snapping out of being zoned out when teacher calls your name/says curse word attention (4 types) - 1. selective - attending to one stimulus when others are present 2. divided - attending to multiple stimulus at the same time 2Brittie Donald, All Rights Reserved © 2025 3. sustained - attending to specific stimulus over a long period 4. alternating - regulating oneself to focus on one thing at a time but switching between them perceptual organization (gestalt principles) - The way our senses interpret information and make it meaningful. similarity - grouping of either auditory or visual stimuli such as dots separated with different colors continuation - when things are lined up we tend to assume they have correlation of randomly placed things closure - brains filling in empty information such as a halfway drawn circle being perceived as a full one proximity - grouping things we see that are spaced apart such as two columns of dots being a little further apart than each dot in the column common region - grouping things together that are in the same enclosed space despite relativity to any other thing outside the space. symmetry & order (prägnanz) - brains will see the simplest form of the object such as the olympic sign being a bunch of circles not curved lines.

Each neuron is composed of a cell body; fine, branching extensions (dendrites) that receive incoming nerve signals; and a single, long extension (axon) that conducts nerve impulses to its branching terminal. sensory structures - the stimuli to which they normally respond; thus, there are photoreceptors (for light), mechanoreceptors (for distortion or bending), thermoreceptors (for heat), chemoreceptors (e.g., for chemical odours), and nociceptors (for painful stimuli) Nociceptors - sensory neurons that are activated b
