The eye enables vision through a process of transduction. Light enters through the pupil and is focused by the lens onto the retina. The retina contains photoreceptor cells that transduce the light into neural signals. These signals are sent through the optic nerve and thalamus to the visual cortex in the brain, where the image is interpreted and visual perception occurs. The eye is able to focus on objects at different distances by changing the thickness of the lens, and the amount of light entering is regulated by the size of the pupil.

Vision and Hearing
The light reflections from a boat travel to the human eye as electromagnetic waves. Once in the eye, the light passes through the cornea and lens, which focus the light onto the retina. The retina converts the light into nerve impulses, which are carried by the optic nerves to the lateral geniculate nucleus. From there, the signals travel to the primary visual cortex in the occipital lobe of the brain, where the visual information is processed.

This document discusses different stages and aspects of sleep. It covers:
1) The main stages of sleep are deep sleep, rapid eye movement (REM) sleep, and non-REM sleep. Deep sleep is restful while REM sleep is when most vivid dreaming occurs.
2) During REM sleep, brain activity is high and similar to when awake but the body is paralyzed, preventing dreams from being acted out.
3) Sleep serves important functions like brain development in infants/children, practicing survival skills, and maintaining overall health and well-being.
U9.3 Nervous System
The document discusses the physiology of nerve impulses in the nervous system. It explains that neurons have two major functional properties - irritability and conductivity. It describes how neurons are polarized at rest and depolarize in response to a stimulus, generating an action potential. The action potential then propagates along the neuron and is transmitted chemically across synapses to other neurons via neurotransmitters. Repolarization restores the neuron's resting potential through ion pumps. Reflexes involve stimuli triggering involuntary responses along neural pathways called reflex arcs.

The Science Behind Sleep
This document summarizes key aspects of sleep including its stages, functions, impacts of sleep deprivation, and relationship to health conditions. It discusses the following main points:
1) Sleep has different stages including NREM stages 1-4 and REM sleep, which can be measured by polysomnography and follow a repeating sleep cycle.
2) Functions of sleep include consolidating memories, regulating emotions and mood, supporting creativity and insight, and restoring immune, metabolic, and restorative functions in the body.
3) Sleep disturbances and deprivation are linked to numerous health conditions and diseases including diabetes, obesity, cancer, and psychological issues, as well as impaired immune and metabolic functioning. Sleep deprivation experiments on rats found
A brief intro into the science of sleep
This document discusses sleep, including what it is, what happens during sleep, what causes sleep, and the functions of sleep. It notes that sleep consists of different stages, including non-REM sleep with four stages and REM sleep. It discusses factors that cause sleep accumulation in the blood and CSF of sleep deprived animals. It also discusses how caffeine and tetrahydrocannabinol affect sleep and potential reasons why sleep is needed, including neural maturation, memory consolidation, and energy conservation, though the physiological functions of sleep remain speculative.
B1b1 how the brain sends signals
The document discusses how neurons send signals in the brain. It explains that neurons have a cell body, axon, and dendrites. Messages are sent through neurons when an electrical impulse travels down the axon and causes it to release neurotransmitters into the synaptic gap. If the neurotransmitters are received by compatible receptors on the dendrites of the next neuron, they will trigger another electrical impulse along that neuron. Key terms involved are neurotransmitters, action potential, synaptic gap, receptors, and the "lock and key" mechanism by which neurotransmitters are selectively received.

Sensation refers to the process by which the senses gather information from the environment through sight, sound, touch, taste, and smell. Sensory receptors detect physical stimuli and transmit this information to the brain. Perception is the interpretation of these sensations, allowing us to make sense of our surroundings. Key concepts include transduction, bottom-up and top-down processing, sensory thresholds, selective attention, and perceptual constancy. The visual, auditory, skin, taste, smell, vestibular and proprioceptive sensory systems were overviewed in the document.
Sensation
Sensation and perception involve two processes - sensation, which is the detection of stimuli by the senses, and perception, which is the interpretation and organization of sensory information. Sensation occurs through sensory receptors in organs like the eyes, ears, and skin that detect stimuli and transmit neural signals. Perception involves higher-level cognitive processes in the brain that allow us to understand and make sense of sensory information. The document provides details on the sensory systems for vision, hearing, smell, taste, and touch and how stimuli are detected and transmitted by receptors in each system to be perceived.

sensation.pptx
Sensation is the process by which our sensory receptors and nervous system receive and represent information about our internal and external environment. There are 5 main sensory systems - vision, hearing, smell, taste and touch. Each system contains receptor cells that transduce physical stimuli into electrochemical signals to the brain. The brain then interprets these signals to form our perceptions. Sensory thresholds, adaptation and neural processing help us detect changes in our environment. Defects in these systems can impair our sensory abilities.

9E Nervous_System Slides PDF.pdf
The document provides information about coordination and the nervous system. It discusses:
- The central nervous system consists of the brain and spinal cord which are linked to sense organs by nerves.
- Neurons transmit electrical signals called impulses throughout the nervous system to coordinate responses.
- A reflex is an automatic response that involves a reflex arc with sensory, inter, and motor neurons without brain involvement.
- The eye contains light-sensitive rods and cones in the retina that detect images and transmit signals along the optic nerve to the brain.
Sensory Systems.pptx
Sensory receptors in the periphery receive stimuli from the environment and transmit this information through neurons to the central nervous system. There are multiple orders of sensory neurons that relay this information. First-order neurons receive input from receptors and transmit to second-order neurons in the spinal cord or brainstem. Second-order neurons cross and transmit to third-order neurons in the thalamus, which relay to fourth-order neurons in the sensory areas of the cortex. The visual system utilizes rods and cones in the retina as receptors, which transmit signals through retinal neurons and the optic nerve to relay nuclei in the brain.

It then discusses visual processing in the lateral geniculate nucleus and primary visual cortex, including retinotopic mapping and different pathways for color, motion, and shape processing.
Sensation & Perception
Sensation is the process of detecting stimuli through the senses, while perception involves interpreting and organizing those sensory inputs. Sensation is bottom-up processing, while perception involves top-down processing using memories and experiences. The document defines key concepts like absolute threshold, difference threshold, and signal detection theory, and describes how the different senses of vision, hearing, taste, smell and touch detect and process stimuli.
The eye
The document summarizes key aspects of visual perception including sensation, perception, the visual perception system, and the anatomy and function of the eye. It discusses how light enters the eye through the cornea and pupil, is focused on the retina by the lens, and is detected by photoreceptors which convert light into electrical signals sent to the brain along the optic nerve. The visual perception process involves light reception by the eye structures, transduction of light into signals by rods and cones, signal transmission to the brain, signal selection and feature detection, and final organization and interpretation into meaningful visual information by the brain.
CGch-3.pptx
The human visual system begins when light enters the eye and forms an image on the retina. The retina contains light-sensitive rods and cones that detect light and color. The optic nerve then sends this visual information to the brain's visual cortex for processing into perceptions of the external world. While the eyes provide sensory input, the brain constructs our experience of vision through complex cognitive and perceptual processes. Our perceptions depend on the interactions between low-level visual detection and higher-level recognition abilities in the brain.

Ch. 14 Clinical psychology: Psychological Disorders
Abnormal Psychology and Psychological Disorders can be summarized as follows:
1. Abnormal psychology involves the study of psychological disorders, which are harmful dysfunctions that result in atypical, disturbing, or inappropriate behavior.
2. Psychological disorders are studied and treated by psychologists, psychiatrists, and other mental health professionals using various theoretical perspectives like psychoanalytic, behavioral, cognitive, and biomedical approaches.
3. Major classes of psychological disorders include anxiety disorders, mood disorders, dissociative disorders, somatoform disorders, schizophrenia, and personality disorders. Each involves distressing or disabling symptoms that impair normal functioning.
Awakenings
Oliver Sacks was a British neurologist who worked in the United States and believed the brain was incredibly complex. In the 1960s, he sought permission to treat a group of catatonic patients in a Bronx hospital with L-Dopa, a drug used for Parkinson's disease, speculating it could help their extreme rigidity. Administering L-Dopa to the patients, who had survived an 1917-1928 epidemic of encephalitis that severely reduced dopamine production, had beneficial effects and revived them from their catatonic states temporarily, as depicted in the film Awakenings based on Sacks' work.
Marshmallow test
The document discusses the relationship between self-control and future success based on the Marshmallow Experiment conducted in the 1960s by Dr. Mischel. In the experiment, 4-year old children were given a marshmallow and told they could eat it now or wait 15 minutes to receive an extra marshmallow. Follow-up studies found that children who were able to delay gratification had higher SAT scores, better grades, and healthier body weights as teenagers compared to those who immediately ate the marshmallow. Additional research with 8th graders also linked greater self-control with higher academic performance.
Ch. 13 personality lecture notes
This document discusses theories of personality from several perspectives. It begins by defining personality as characteristic patterns of thoughts, feelings, and behaviors that persist over time and across situations. It then outlines Freud's psychoanalytic theory, including the id, ego, superego, defense mechanisms, and stages of psychosexual development. It also discusses trait theories, behaviorist perspectives, humanistic theories like Carl Rogers' concept of self-actualization, and social-cognitive approaches like Albert Bandura's reciprocal determinism. The document examines various methods of assessing personality, including projective tests, self-report inventories, and the widely used MMPI.
Ch. 12: Human Emotions & Stress
There are several theories on the nature of emotions. The James-Lange theory proposes that physiological arousal precedes emotional experience. The Cannon-Bard theory argues that emotional experience and physiological arousal occur simultaneously. The two-factor theory suggests that both biological and cognitive factors interact to influence the intensity of emotional experience. Basic emotions include happiness, sadness, fear, anger, surprise and disgust.
Motivation

Key motivators discussed include basic drives, achievement, and belongingness.
Important women in psychology history
This document summarizes the contributions of several important female psychologists throughout history whose work was often overlooked or ignored. It describes how Anna Freud extended her father's psychoanalytic theories to child psychology, how Mamie Phipps Clark's doll experiments influenced the Brown vs. Board of Education decision, and how Mary Ainsworth developed the Strange Situation assessment of attachment in children. It also outlines the influential research of Sandra Bem, Mary Whiton Calkins, Leta Hollingworth, Karen Horney, Melanie Klein, Brenda Milner, and Susan Blackmore on gender roles, neuropsychology, psychoanalysis, and the science of memes.

Eggsperiment point breakdown
This document outlines the point breakdown and requirements for an egg parenting simulation project. It details that students can earn a total of 100 points by caring for an egg daily, decorating and customizing an egg carrier, and submitting egg logs and video diaries by various deadlines. It reminds students to write their name on the egg carrier and document anyone else who watches the egg. It also states that the teacher will not watch a student's egg for more than one class period and that she is always watching. Finally, it lists options for submitting the video diaries portion of the 175-point project due on Monday, February 3rd by 10:00 pm.
Principles of classical conditioning
The document discusses classical conditioning, a form of learning. Classical conditioning occurs when a previously neutral stimulus becomes associated with an unconditioned stimulus to elicit a conditioned response. Key terms are defined, including unconditioned stimulus, unconditioned response, conditioned stimulus, and conditioned response. Classical conditioning involves pairing a previously neutral stimulus that does not naturally elicit a response with an unconditioned stimulus that reflexively produces a response, so that the formerly neutral stimulus comes to produce a learned response.
2019 AP Psych Photo contest
This document discusses forced perspective, an optical illusion technique that makes objects appear farther, closer, larger, or smaller than their actual size by manipulating scale and the viewer's vantage point. It also provides voting guidelines for selecting favorite photos from a school contest by emailing numbers of the top 3 photos to a provided email address by December 11th. The winning team of the photo contest will receive a prize.
Notes on vision
The document discusses the process of vision and how the eye works. It begins with light entering the eye and being projected onto the retina. Photoreceptors in the retina are sensitive to light and transmit visual information via the optic nerve to the brain. The brain processes this input in the visual cortex located in the occipital lobe, where features are detected through parallel processing. The key stages are gathering light entering the eye, transduction of light signals in the retina, and processing of this information in the visual areas of the brain.
Nature vs. Nurture
Heredity is the passing of traits from parents to offspring through genes. Individuals have two genes for each trait, one from each parent. Heredity is vital for transmitting both physical traits like height and eye color as well as psychological traits such as shyness and disorders like anxiety. The document discusses genes and chromosomes, the basic units of heredity, and how they determine traits and can cause disorders if abnormal like in Down syndrome where there is an extra chromosome.
Hispanic Heritage month psychologists
George I. Sanchez was one of the first to challenge biased intelligence research and question the use of IQ tests. He founded Chicano Psychology and was the first national president of LULAC. Martha Bernal was the first woman of Mexican descent to earn a PhD in clinical psychology in the US. She pioneered the use of learning theory and methods in assessing and treating children. John Garcia conducted research showing that rats could detect and avoid radiation, and his taste aversion research changed theories of associative learning. Melba Vasquez was one of the first recipients of the APA's minority fellowship and co-founded Division 45. She became the first Latina president of the APA.
Perspectives in psychology
The document outlines six major perspectives in psychology and provides examples of how each perspective might explain the outrageous behavior of NBA player Dennis Rodman, known for cross-dressing, rapidly changing hair colors, and other stunts. The perspectives discussed are biological, evolutionary, humanistic, psychodynamic, behavioral, and cognitive perspectives. For each perspective, the document provides a brief example of how that perspective could interpret and explain Rodman's behavior.

- 1. Transduction • Transforming signals into neural impulses. • Information goes from the senses to the thalamus , then to the various areas in the brain. Remember Ethan in Sky High. He changes his body to slime. Solid form to liquid form. Change from one form of energy to another.
- 2. Energy vs. Chemical senses Energy Senses Chemical Senses Vision Touch Hearing Taste Smell
- 3. Vision • Our most dominating sense. • Visual Capture

- 8. A Journey Through the Human Eye: How We See • http://www.youtube.com/watch?v=gvozcv8pS 3c
- 9. THE EYE AND VISION • Light enters the eye and then is projected onto a surface • The amount of light that enters the eye is determined by the size of the pupil which adjusts automatically to the amount of light entering the eye • Once light enters the eye, it encounters the lens which adjusts to the distance of objects by changing its thickness
- 10. Question: How does the eye enable vision? • These changes project a clear image of the object onto the retina, which consists of neurons that are sensitive to the light called photoreceptors • Once the light hits the photoreceptors, a nerve carries the visual input into the brain where the information is relayed to the visual area of the occipital lobe THE EYE AND VISION
- 11. 11 Chapter 4
- 13. Phase One: Gathering Light • The height of a wave gives us it’s intensity (brightness). • The length of the wave gives us it’s hue (color). • The longer the wave the more red. • The shorter the wavelength the more violet.
- 14. Phase Two: Getting the light in the eye
- 16. Transduction Continued • Order is Rods/Cones to Bipolar to Ganglion to Optic Nerve. • Sends info to thalamus- area called lateral geniculate nucleus (LGN). • Then sent to cerebral cortexes. • Where the optic nerves cross is called the optic chiasm.
- 18. Phase Four: In the Brain • Goes to the Visual Cortex located in the Occipital Lobe of the Cerebral Cortex. • Feature Detectors. • Parallel ProcessingWe have specific cells that see the lines, motion, curves and other features of this turkey. These cells are called feature detectors.
