no photoreceptors heretrichromatic theory - answer-young-helmholtz theory, says that our receptors respond to three primary colors depending on short, medium, or long wavelengths opponent-process theory - answer-we perceive colors in terms of paired opposites, red vs green, yellow vs blue, white vs black negative afterimages - answer-experiences of one color after the removal of another color constancy - answer-the tendency of a color to appear nearly the same under a variety of lighting conditions retinex theory - answer-we perceive color when the cerebral cortex compares carious retinal patterns sound waves - answer-vibrations of the air or of another medium Hz (hertz) - answer-measures frequency of a sound frequency - answer-number of cycles (vibrations) that a sound wave goes through per second pitch - answer-high frequency = high pitch low frequency = low pitch loudness - answer-perception depending on the amplitude of the waves, higher amplitude means greater sound intensity - answer-amplitude of wavescochlea - answer-snail shaped organ in inner ear filled with fluid and the receptors for hearing three bones in ear - answer-malleus (hammer) incus (anvil) stapes (stirrup) vestibular sense - answer-detects the tilt of the head, orientation of the head with respect to gravity, and the acceleration of the head cutaneous senses - answer-somatosensory system gate theory of pain - answer-pain messages must pass though a gate, presumably in the spinal cord, that can block messages... means that other input, like touching or something, can close the gate and prevent pain messages from getting to the brain phantom limbs - answer-continuing sensations including pain, in a limb long after it has been amputated taste - answer-detection of chemicals on the tongue taste buds - answer-the taste receptors located on the folds of the surface of the tongue olfaction - answer-sense of smell pheromones - answer-chemicals released by mammals into the environment synesthesia - answer-a condition in which a stimulus of one type, such as sound, also elicits another experience such as colorPerceptual Psychology - answer-a field of psychology that attempts to understand how we perceive the world around us Gestalt Psychology - answer-a group of perceptual psychologists that study and define the rules that we use to perceive the world Retinal disparity - answer-the distance of an object is determined by the difference of the signals received by the two eyes, binocular cue for depth perception Convergence - answer-the distance of an object is determined by the amount of eye movement required to focus on an object, binocular cue for depth perception object size - answer-monocular cue, objects closer look bigger accommodation - answer-monocular cue, our brains can detect how much the lens of the eye needed to shift in order to focus on an object detail - answer-monocular cue, relative clarity, more detail signifies a closer object ames room - answer-Trapezoidal room; creates an optical illusion with one large and one small person muller-lyre Illusion - answer-horizontal lines appear to be different lengths due to surrounding angled lines, though they are not Developmental Psychology - answer-the scientific study of the changes of the mind and related systems throughout the lifespan, In psychology, we believe that human beings are constantly changing, not just becoming smarter or more experiencedWhat changes occur in the lifespan? - answer-physical, social, cognitive What causes the changes in our lifetime? - answer-genetics, experience snowflake analogy - answer-Though no two of us are completely identical, many of us possess similar qualities and grow in the same way Moreover, if we study the factors that shape one person's development, we might be able to apply those to another person Goal of Developmental Psychologists that Look at Change - answer-Tracking/Predicting Typical Development; Understanding the Triggers and Causes to Typical Development; Examining Non-Traditional Development In Order to Understand Why it Occurred and How It Impacts the Individual puberty - answer-the process of physical and mental change from childhood to adulthood that is initiated by an increase of hormones in the hypothalamus and the pituitary gland that are sent to the gonads which produce hormones, onset linked to social and nutritional factors gender differences in puberty - answer-Women = earlier (9-13) and slower; estradiol (more overall increase) and testosterone (2x) Men = later (11-15); testosterone (8x) and estradiol (small increase) Linked to changes in reproductive abilities, and physical, cognitive, and socioemotional attributes Precocious puberty - answer-the very early onset and rapid progression of puberty, 10X more common in girls, leads to riskier behavior and more emotional/social problems, bad future impact too for girls not guys
