Psychology Study Guide: 1) Toward information processing: - Tolman: learning could occur in absent reinforcement - latent learning -Chomsky: linguistics, disagreed with the idea that language is a behavior, Skinner can’t account for language. - Kuhn -Paradigm shift: seeing same information- perceive it differently Information processing - Human as computer: information processor, store information for later use. 2) Sensation and Perception: -Sensation: extract, process of receiving physical energy from the external world - Perception: interpret, acquiring, interpreting, selecting, and organizing, sensory information Distal stimulus: object in the world, I.e. the apple on a table Proximal stimulus: image on the retina, knowledge comes from the senses I.e. apple that you see in your head Perception: everything we know about the object -Visual agnosia: impairments in the ability to interpret (but not see) -Prosopagnosia: inability to perceive faces 3) Basics of Sensation -Five special senses -Physical inputs: Light waves = vision Sound waves = hearing Odor molecules = smell Food = taste Pressure = touch -Other senses Kinesthesis : info that comes from receptors in muscles tendons and joints informs us about our movements-- auditory receptors are called hair cells, 15,000 in each ear. Vestibular : receptors in cavity within the inner ear and signal movements in the head Skin : at least four different skin receptors give rise to sensations of pressure, warmth, cold, and pain. -Psychophysics: the study of the specific relationship between the properties of the physical stimulus and the psychological sensory experience. Physical and sensory experience. Goal: chart the relationship between physical characteristics of stimulus and individuals perception. -Signal detection theory: minimal intensity required for person to recognize stimulus. Signal Detection: HIT : yes stimulus response yes MISS : yes stimulus, response no FALSE ALARM: stimulus absent, response yes CORRECT NEG : stimulus absent, response no -Measuring sensory intensity: Absolute threshold: something becomes noticeable to our senses, the softest sound we can hear or the slightest touch we can feel, anything less than this goes unnoticed Difference threshold: the smallest stimulus change that the observer can reliably detect, recognizing if the stimulus changes Just Noticeable difference: psychological entity observers ability to discriminate- the actual change
