Perception: the process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events 

Bottom-up Processing: analysis that begins with the sensory receptors and works up to the brain’s integration of sensory information 

Top-down Processing: information processing guided by higher-level mental processes, as when we construct perceptions drawing on our experience and expectations 

Psychophysics: the study of relationships between the physical characteristics of stimuli, such as their intensity, and our psychological experience of them 

Absolute threshold: the minimum stimulation needed to detect a particular stimulus 50 percent of the time ]]> 2017-10-16 14:27:12 UTC https://padlet.com/kenzyb57/1xgwzweit2wh/wish/197371220 kenzyb57 https://padlet.com/kenzyb57/1xgwzweit2wh/wish/197374382 Signal Detection Theory: a theory predicting how and when we detect the presence of a faint stimulus amid background stimulation. Assumes there is no single absolute threshold and that detection depends partly on a person’s experience, expectations, motivation, and level of fatigue 

Subliminal: below ones absolute threshold for conscious awareness 

Priming: the activation, often unconsciously, of certain associations, thus predisposing ones perception, memory, or response ]]> 2017-10-16 14:32:09 UTC https://padlet.com/kenzyb57/1xgwzweit2wh/wish/197374382 kenzyb57 https://padlet.com/kenzyb57/1xgwzweit2wh/wish/197376698 Difference Threshold: the minimum difference between two stimuli required for detection 50 percent of the time. We experience the difference threshold as a just noticeable difference 

Weber’s Law: the principle that, to be perceived as different, two stimuli must differ by a constant, minimum percentage 

Sensory Adaptation: diminished sensitivity as a consequence of constant stimulation 

Selective Attention: the focusing of conscious awareness on a particular stimulus, as in the cocktail party effect 

Inattentional Blindness: failing to see visible objects when our attention is directed elsewhere ]]> 2017-10-16 14:35:57 UTC https://padlet.com/kenzyb57/1xgwzweit2wh/wish/197376698
