Document Summary

: receptor cells pick up energy from stimuli. Transduction: stimulus energy is transformed into a neural impulse. Transmission: neural impulse is delivered to the brain. Bottom-up processing characteristics of the stimuli. (simple & new stimuli) Top-down processing: experience/expectation. (complex & ambiguous stimuli) relies on. Perpetual sets; mental schemas shaped by experience, affecting our interpretation. (context, culture, emotion, motivation/physical state) Absolute threshold: minimum intensity needed to detect a stimulus (1/2) the time it is encountered. (everything below = subliminal) Difference threshold: with background noise, a stimulus needs a specific intensity to be detected; weber"s law- 2 stimuli must differ by a constant minimum percentage. Signal detection theory: stimulus detection depends on a person"s previous experience of the stimulus and current state. Sensory adaptation: sensory organs tune out constant stimuli to detect novelty in our surroundings: photoreceptors are sensory neurons that convert light energy into nerve impulses:
