Sensation Flashcards
the process that occurs when special receptors in the sense organs are activated, allowing various forms of outside stimuli to become neural signals in the brain
Sensation
the process of converting outside stimuli, such as light, into neural activity
Transduction
specialized forms of neurons, the cells that make up the nervous system
Sensory Receptors
disorder in which the signals from the various sensory organs are processed in the wrong cortical areas, resulting in the sense information being interpreted as more than one sensation
Synesthesia
the smallest difference between two stimuli that is detectable 50 percent of the time, and this law simply means that whatever the difference between stimuli might be, it is always a constant
Just Noticeable Differences (JND, or the Difference Threshold)
by Ernst Weber
the lowest level of stimulation that a person can consciously detect 50 percent of the time the stimulation is present
Absolute Threshold
by Gustav Fechner
stimuli that are below the level of conscious awareness
Subliminal Stimuli
people believe that subliminal stimuli act upon the unconscious mind, influencing behavior in a process called
Subliminal Perception
way of analyzing what stimuli we respond to;
used to compare our judgments, or the decisions we make, under uncertain conditions
Signal Detection Theory
the way the brain deals with unchanging information from the environment
Habituation
another process by which constant, unchanging information from the sensory receptors is effectively ignored
Sensory Adaptation
