Sensation and perception are actually parts of one continuous process. Phrenology definition, a psychological theory or analytical method based on the belief that certain mental faculties and character traits are indicated by the configurations of the skull. (p. 229), the point at which the optic nerve leaves the eye, creating a "blind" spot because no receptor cells are located there. we observe the manifestation of mental processes, but NOT..... analyze biological factors involved in behavior and mental processes, thinking, learning, memory, problem-solving, interested in what makes people unique/how behavior is affected by "personality traits", study changes in behavior and mental processes that occur over a lifetime, study the ways people influence one another, work as mental health counselors and study causes and how to treat disorders, study and correct abnormal behavior and mental processes, try to help stressful conditions (counseling) that lead to disorders, conduct research and develop theories about teaching and learning, specialize in testing and diagnosing learning disabilities, I/O (Industrial/Organizational Psychologists), study factors that affect workers and the organizations that employ them, the rational investigation of the truths and principles of being, knowledge, or conduct, believe we were born as a blank slate; believe knowledge is ONLY gained through observance and EXPERIENCE, "structuralism" - study the mind by breaking it down into its basic components or "structures", inward look; describing in detail the experience of feeling and seeing something, "functionalism" - how and why the mind "functions" the way it does to allow us to live and adapt, genetics, electrical and chemical activity, and hormones are most important, (Freud) unconscious processes and unresolved conflicts from past influence behavior and mental processes, behavior is determined by learned habits that are a by-product of rewards and punishments, people strive to grow, develop, and reach their full potentials as humans, humans are info. (Pulled from other lists.) Gestalt psychologists emphasized our tendency to integrate pieces of information into meaningful wholes. Sound waves strike one ear sooner and more intensely than the other. One theory says that, like our ordinary senses, ESP is energy moving from one point to another point. (p. 237), depth cues, such as interposition and linear perspective, available to either eye alone. It defines each important topic related to Perception in a psychology course Chapter 3 in the David Myers textbook. (p. 244), the innermost part of the ear, containing the cochlea, semicircular canals, and vestibular sacs. Pain reflects bottom-up sensations (such as input from nociceptors, the sensory receptors that detect hurtful temperatures, pressure, or chemicals) and top-down processes (such as experience, attention, and culture). Parapsychology is the study of paranormal phenomena, including extrasensory perception (ESP) and psychokinesis. (p. 219), the activation, often unconsciously, of certain associations, thus predisposing one's perception, memory, or response. What three steps are basic to all our sensory systems? (p. 244), hearing loss caused by damage to the mechanical system that conducts sound waves to the cochlea. Psychology is by definition an inexact science. The science of behavior and mental processes, any activity that can be observed, recorded, and measured, thoughts, feelings, memories, perceptions, beliefs. The brain analyzes the minute differences in the sounds received by the two ears and computes the sound's source. (p. 259). Binocular cues, such as retinal disparity, are depth cues that rely on information from both eyes. Our physical and emotional context, as well as our motivation, can create expectations and color our interpretation of events and behaviors.

Usually included in this category of phenomena are telepathy, or thought transference between persons; clairvoyance, or supernormal awareness of objects or events not necessarily known to others; and precognition, or knowledge of the future. Our absolute threshold for any stimulus is the minimum stimulation necessary for us to be consciously aware of it 50 percent of the time. Sensory adaptation (our diminished sensitivity to constant or routine odors, sounds, and touches) focuses our attention on informative changes in our environment. 116+3 sentence examples: 1.

(p. 257), the sense of body movement and position, including the sense of balance. Color constancy is our ability to perceive consistent color in objects, even though the lighting and wavelengths shift. Since 2004, Dr Sutton has been working as an Administrator, first as the Director of Assessment for the University. Psychology: The study of the mind and mental processes, especially in relation to behavior.

Sensation and Perception - Psychology Class Notes Test and improve your knowledge of GRE Psychology: ... sensation and perception flashcards on Quizlet. Our senses (1) receive sensory stimulation (often using specialized receptor cells); (2) transform that stimulation into neural impulses; and (3) deliver the neural information to the brain. Human perception is highly imperfect and by def (p. 227), the adjustable opening in the center of the eye through which light enters. (p. 228), the transparent structure behind the pupil that changes shape to help focus images on the retina. (p. 234), the organization of the visual field into objects (the figures) that stand out from their surroundings (the ground). Monocular cues (such as relative size, interposition, relative height, relative motion, linear perspective, and light and shadow) let us judge depth using information transmitted by only one eye. People blind from birth who gained sight after surgery lack the experience to visually recognize shapes, forms, and complete faces. Home; About; wavelength definition psychology quizlet (pp. Our brain constructs our experience of an object's color or brightness through comparisons with other surrounding objects.

Learn vocabulary, terms, and more with flashcards, games, and other study tools. Definition. how widely dispersed a set of … Sound waves are bands of compressed and expanded air. What does research on restored vision, sensory restriction, and perceptual adaptation reveal about the effects of experience on perception? Typically, proponents of this theory say ESP energy takes the form of electromagnetic waves -- just like light, radio and X-ray energy -- that we haven't been able to detect scientifically. (p. 239), perceiving objects as unchanging (having consistent shapes, size, brightness, and color) even as illumination and retinal images change. Place theory explains how we hear high-pitched sounds, and frequency theory explains how we hear low-pitched sounds. What are the claims of ESP, and what have most research psychologists concluded after putting these claims to the test? Assumes there is no single absolute threshold and that detection depends partly on a person's experience, expectations, motivation, and alertness. (p. 229), the central focal point in the retina, around which the eye's cones cluster. After processing by bipolar and ganglion cells in the eyes' retina, neural impulses travel through the optic nerve, to the thalamus, and on to the visual cortex. How do we experience taste and smell, and how do they interact? (p. 228), the nerve that carries neural impulses from the eye to the brain. Researchers in psychophysics study the relationships between stimuli's physical characteristics and our psychological experience of them.

Learn vocabulary, terms, and more with flashcards, games, and other study tools. Up to then, 354 auto-ganzfeld sessions had taken place during 11 studies. Parapsychology is the study of paranormal phenomena, including extrasensory perception (ESP) and psychokinesis. We experience the difference threshold as a just noticeable difference (or jnd). people who believe in extrasensory perception or ESP. Definitions are for triggering other information. Telepathy, direct transference of thought from one person (sender or agent) to another (receiver or percipient) without using the usual sensory channels of communication, hence a form of extrasensory perception (ESP).

Perceptual set is a mental predisposition that functions as a lens through which we perceive the world. Extrasensory perception (ESP) refers to the ability to obtain information about the world around you without using the normal five senses of sight, touch, taste, hearing, and smell. what does random assignment to experimental or control groups do? (p. 237), a binocular cue for perceiving depth: By comparing images from the retinas in the two eyes, the brain computes distance—the greater the disparity (difference) between the two images, the closer the object. Contrasts with the step-by-step (serial) processing of most computers and of conscious problem solving. (A combination of the two theories explains how we hear pitches in the middle range.) While the existence of telepathy has not yet been proved, some parapsychological (p. 218), the minimum stimulation needed to detect a particular stimulus 50 percent of the time. In pointing out that the whole may exceed the sum of its parts, they noted that we filter sensory information and construct our perceptions. Sensation & Perception in Psychology - Chapter Summary and Learning Objectives. Brightness (or lightness) constancy is our ability to perceive an object as having a constant lightness even when its illumination—the light cast upon it—changes. (p. 221), diminished sensitivity as a consequence of constant stimulation. This document provides a study guide outline of all the important terms definitions psychological processes and ideas. (p. 250), the principle that one sense may influence another, as when the smell of food influences its taste. Taste is a composite of five basic sensations—sweet, sour, salty, bitter, and umami—and of the aromas that interact with information from the taste receptor cells of the taste buds. (p. 236), depth cues, such as retinal disparity, that depend on the use of two eyes. What is Sensation in Psychology? In sensation, the transforming of stimulus energies, such as sights, sounds, and smells, into neural impulses our brain can interpret. 3. (p. 235), the perceptual tendency to organize stimuli into coherent groups. Psychology can off a lot of insight regarding the big questions people have a about love, life and the pursuit of happiness. How did the Gestalt psychologists understand perceptual organization, and how do figure-ground and grouping principles contribute to our perceptions? Weber's law states that two stimuli must differ by a constant proportion (not a constant amount) to be perceived as different. How do we use binocular and monocular cues to perceive the world in three dimensions and perceive motion? 513-368-5694. (p. 228), retinal receptor cells that are concentrated near the center of the retina and that function in daylight or in well-lit conditions. Although intimately related, sensation and perception play two complimentary but different roles in how we interpret our world. Experience guides our perceptual interpretations. Individual absolute thresholds vary, depending on the strength of the signal and also on our experience, expectations, motivation, and alertness. Taste and smell are chemical senses. Perception is the process of organizing and interpreting this information, enabling recognition of meaningful events. Contemporary research has found three types of cones, each most sensitive to the wavelengths of one of the three primary colors of light (red, green, or blue). (p. 219), below one's absolute threshold for conscious awareness. In the visual cortex, feature detectors respond to specific features of the visual stimulus. 4. (p. 244), a device for converting sounds into electrical signals and stimulating the auditory nerve through electrodes threaded into the cochlea. One theory of pain is that a "gate" in the spinal cord either opens to permit pain signals traveling up small nerve fibers to reach the brain, or closes to prevent their passage. extrasensory perception (ESP) the controversial claim that perception can occur apart from sensory input; includes telepathy, clairvoyance, and precognition parapsychology The three most testable forms of ESP are telepathy (mind-to-mind communication), clairvoyance (perceiving remote events), and precognition (perceiving future events). (p. 227), the amount of energy in a light or sound wave, which we perceive as brightness or loudness, as determined by the wave's amplitude. Green – Important People & Contributions Medical Model – Proposes to Think of Abnormal Behavior as a Disease. (p. 220), the principle that, to be perceived as different, two stimuli must differ by a constant minimum percentage (rather than a constant amount).

Through parallel processing, the brain handles many aspects of vision (color, movement, form, and depth) simultaneously. How do our expectations, contexts, emotions, and motivation influence our perceptions? the extent to which an experimental measure is free from error. Introduction to Sensation and Perception. (p. 229), nerve cells in the brain that respond to specific features of the stimulus, such as shape, angle, or movement.

For example, some cells are stimulated by green and inhibited by red; others are stimulated by red and inhibited by green. (p. 227), the dimension of color that is determined by the wavelength of light; what we know as the color names blue, green, and so forth. the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment. Supercell clusters in other critical areas respond to more complex patterns. Neighbours by definition live close by . Signal detection theory predicts how and when we will detect a faint stimulus amid background noise. Sound waves vary in amplitude, which we perceive as differing loudness, and in frequency, which we experience as differing pitch. (p. 219), a theory predicting how and when we detect the presence of a faint stimulus (signal) amid background stimulation (noise). Perceptual constancy enables us to perceive objects as stable despite the changing image they cast on our retinas. What theories help us understand color vision? (North America and Western Europe) people tend to focus on and value personal rather than group goals and achievement; (Japan and other parts of Asia) people tend to think of themselves as part of family or work groups; cooperative efforts aimed at advancing welfare of these groups is highly valued; fear of rejection by the group is common, how people will behave under certain circumstances, the process of assessing claims and making judgments based on well-supported evidence, procedures used to develop questions, accumulate evidence, and draw conclusions, a statement that describes relationship between two or more things, things that can "vary" or change in ways that are measurable, define in measurable terms the variables in the hypothesis, design study and collect data; determine who are the "subjects"; determine procedures to be used in collecting the data, scientific journals, newspapers, targeted groups (ex: National Education Association, Chamber of Commerce), statements that are designed to explain a phenomenon, watching, used to study how people or animals behave in their natural environments, no random assignment, no experimental treatments/conditions, cannot make cause and effect conclusions, using questionnaires/interviews to obtain info about attitudes, beliefs, opinions, and personality characteristics, give us descriptive info, no random assignment, no experimental treatments/conditions, cannot make cause and effect conclusions. AP Psychology Sensation and Perception Flashcards | Quizlet Start studying Psychology- Chapter 3 (Sensation and Perception). September 21, 2016. otherwise known as 'ESP', is the alleged ability to sense events occuring around oneself, through an extra sense or means such as; clairvoyance, telepathy, psychokinesis (although more loosely) and even pre-cognition. How do the eye and the brain process visual information? Transduction is the process of converting one form of energy into another. (p. 229), the process by which the eye's lens changes shape to focus near or far objects on the retina. (p. 233), the theory that opposing retinal processes (red-green, yellow-blue, white-black) enable color vision. Page 6/10. Top-down processing is information processing guided by high-level mental processes, as when we construct perceptions by filtering information through our experience and expectations. How do perceptual constancies help us organize our sensations into meaningful perceptions? (p. 244), hearing loss caused by damage to the cochlea's receptor cells or to the auditory nerves; also called nerve deafness. "People are correct in believing that they have an ability to sense changes in their environment even when they cannot verbally identify what those changes are," study co-author Dr. Piers Howe, a psychology professor at the University of Melbourne in Australia, told The Huffington Post in an email. the sum of all the values, rules of behavior, forms of expression, religious beliefs, occupational choices, and the like among a group of people who share a common language and environment. an intensive examination of behavior/mental processing in a particular individual, group, or situation; helps us to predict, shows a relationship, used to determine whether two variables or measures are related (ex: ACT scores and college GPA; winter and depression), researcher makes a change in one variable and then observes the effect of that change on another variable while holding other variables constant; random assignment; if differences between groups are found, variables other than independent variables cannot account for those differences; ONLY method that can identify cause and effect relationships; results cannot be generalized too broadly, something that can occur with different values (ex: height, weight, ratings on a questionnaire), statement about what you expect to happen if certain conditions are true (if/then format), the variable that the experimenter manipulates or changes ("if" part of a hypothesis), the variable that concerns the responses the participants make ("then" part of hypothesis), variables that will interfere with data and affect the dependent variable if not controlled, experiencing treatment condition (variable is present in this group), matched to be similar to experimental group except they don't receive experimental treatment, ensures groups are the same from the start. (p. 231), the processing of many aspects of a problem simultaneously; the brain's natural mode of information processing for many functions, including vision. A clinic for women would, by definition, deal with pregnancy and childbirth. (p. 238), an illusion of movement created when two or more adjacent lights blink on and off in quick succession. What are the characteristics of air pressure waves that we hear as sound, and how does the ear transform sound energy into neural messages? The Young-Helmholtz trichromatic (three-color) theory proposed that the retina contains three types of color receptors. Depth perception is our ability to see objects in three dimensions and judge distance. Extrasensory perception (ESP), perception that occurs independently of the known sensory processes. The "gate" is opened by the activity of pain signals traveling up small nerve fibers and is closed by activity in larger fibers or by information coming from the brain. Through kinesthesis, we sense the position and movement of our body parts. After entering the eye and being focused by a lens, light energy particles (from a thin slice of the broad spectrum of electromagnetic energy) strike the eye's inner surface, the retina. What do we mean by bottom-up processing and top-down processing? (p. 231), Young-Helmholtz trichromatic (three-color) theory, the theory that the retina contains three different color receptors—one most sensitive to red, one to green, one to blue—which, when stimulated in combination, can produce the perception of any color. if the # is not between -1 and +1 then... increases in one variable accompanied by increases in another variable, increases in one variable accompanied by decreases in another variable, believed learning is the most important cause of behavior, studied operant conditioning, a learning process through which rewards and punishments shape, maintain, and change behavior. Andrea is interested in the kinds of mental changes that take place in people between the ages of 45 and 65. Place theory proposes that our brain interprets a particular pitch by decoding the place where a sound wave stimulates the cochlea's basilar membrane. Clinical psychology is concerned with diagnosing and treating disorders of the brain, emotional disturbances, and behavior problems. The cones detect fine detail and give rise to color sensations. Enrich your vocabulary with the English Definition dictionary Our ears detect these changes in air pressure and transform them into neural impulses, which the brain decodes as sound. (p. 236), a laboratory device for testing depth perception in infants and young animals. (p. 247), in hearing, the theory that the rate of nerve impulses traveling up the auditory nerve matches the frequency of a tone, thus enabling us to sense its pitch. 219, 316), the minimum difference between two stimuli required for detection 50 percent of the time.
