- pupils become smaller (greater difficulty when lighting is dim & when it suddenly changes) - pupils slower to dilate - dark adaptation is slower - lens become less denser and less flexible - yellowing of lens - lens and gelatinous liquid behind lens are less transparent - visual acuity decreases - sensory receptor cells in the retina may die or not function as efficiently as they did before - retina change = decreased visual field/loss of peripheral vision = tunnel vision
What is a variable interval reinforcement schedule?
- unannounced pop-quiz - slow steady responding
What is adaptation?
- the process of adjusting to the demands of environment (Piaget, 1971) - occurs through two complementary processes: assimilation and accommodation

Age-related macular degeneration - damage to the cells in the retina responsible for central vision
What is Perry & Punishment?
Although it is generally best to use more positive approaches before resorting to punishment, punishment can make children comply with parents' demands in the short run (Benjet & Kazdin, 2003). Spanking or another form of physical punishment can be effective in changing behavior in the longer run if it: (1) Is administered immediately after the act (not hours later, when the child is being an angel), (2) Is administered consistently after each offense, (3) Is not overly harsh, (4) Is accompanied by explanations, (5) Is administered by an otherwise affectionate person, and (6) Is used sparingly and combined with efforts to reinforce more acceptable behavior

What is behavior modification?
Applying operant principles to changing specific needs
Describe the development of attention from infancy to adolescence.
As children get older... 1) their attention spans become longer 2) become more selective in what they attend to 3) better able to plan and carry out systematic strategies for using their senses to achieve goals Infancy: - selective attention: deliberately concentrating on one thing while ignoring something else - with age, attention becomes more selective and less susceptible t0 distraction - @ 2 yrs, able to form plans of actions --> guides what they focus on and what they ignore - systematic attention Adolescence: - longer attention spans - improved considerably between childhood and adulthood (b/c of increase myelination of the portions of the brain that help regulate attention) - become more efficient at ignoring irrelevant information - can divide their attention more systematically between two taskswwe
How do newborns view patterns/what do they prefer?
Attracted to moderately complex patterns - prefers a clear pattern like a bold checkerboard
What is operant conditioning?
B.F. Skinner - a learner's behavior becomes either more or less probable depending on the consequences it produces - acquiring and modifying "voluntary" or non-reflexive behavior by the application of reinforcers of punishers - organisms behave in ways that bring them desirable consequences or help them avoid unpleasant ones
How do babies use common motion (@ 4 months) to help identify contour or figures?
Babies are attracted to displays that are *dynamic or contain movement* - newborns can and do track a moving target with their eyes (although it is imprecise, unless the target it moving slowly) - infants also look longer at moving objects and perceive their forms better than stationary ones - expects all pars of an object to move in the same direction at the same time and USE COMMON MOTION in determining what is or is not part of the same object
What tactile sense can babies detect?
Babies can detect and react to touch or pressure, heat or cold, and painful stimuli
What is the social cognitive theory (observational)?
Bandura - claims that humans are cognitive beings whose active processing of information plays a critical role in their learning, behavior, and development - learning by observing the behavior of other people (models)

Know some things about expertise in a domain & cognitive ability...
Critics concluded that Piaget underestimated the cognitive abilities of young children; recent studies suggest that children master some Piagetian concepts earlier than Piaget believed they did, although defenders of Piaget would question whether some of the simplified tasks used by later researchers really demonstrate that young children have fully mastered the concepts tested

Ecological development: his theory was key in changing the perspective of developmental psychology by calling attention to the large number of environmental and societal influences on child development Microsystem: Immediate environment Mesosystem: Interrelationships of microsystems Macrosystem: External, social settings that have indirect effects Exosystem: Society, world events, the planet, historical era Chronosystem: Time
Who performed the visual cliff experiments?
Eleanor Gibson & Richard Walk
Elkind: imaginary audience, personal fable?
Elkind describes how young adolescents, because they are undergoing major physiological changes, are preoccupied by themselves. The egocentrism of adolescents lies in their belief that others are as preoccupied with their appearance and behavior as they are. As a consequence, the adolescent anticipates other people's responses and thoughts about herself, and is, in a way, constantly creating or reacting to an imaginary audience. - confusing your own thoughts of a hypothesized audience for your behavior (getting spaghetti on your shirt and thinking that people may think of you as a slob) According to Elkind, this probably plays a role in the self-consciousness so common in early adolescence, as well as other experiences in this period of life. Elkind also introduced the idea of the personal fable, in which the adolescent constructs a story about herself, a version of her life stressing the uniqueness of her feelings and experiences. Indeed, these ideas of personal uniqueness are also seen in a common conviction that the adolescent will not die. Elkind stressed how he found these concepts useful in understanding and treating troubled adolescents. Elkind believes the egocentrism of early adolescence usually lessens by the age of 15 or 16 as cognitive development proceeds. - tendency to think that you and yours thoughts and feelings are unique (being in love and saying the no one in the history of the whole human race has ever felt such heights of emotion)
Tertiary Circular Reactions (12 - 18 months)?
Experimentation to find new ways to solve problems or produce interesting outcomes (e.g., explore bathwater by gently patting it, then hitting it vigorously and watching the results; or stroke, pinch, squeeze, and pat a cat to see how it responds to varied actions)
What did Pavlov do?

What is glaucoma?
Increased fluid pressure in the eye that causes damage to the optic nerve and can cause a progressive loss of peripheral vision, and ultimately, blindness
Who is Thorndike and what did he believe?
Law of Effect - the response to a stimulus is affected by the consequence of that behavior - trial & error learning results in some behaviors (those follows by a good consequence) being "stamped in", while others (those follows by discomfort or unpleasant consequences) are stamped out - behavioral response is affected by the consequence of that behavior - behavior changes because of its consequences - rewarded behavior is likely to reoccur
What is latent learning?
Learning occurs but is not evident in behavior; children can learn from observation even though they do no imitate (perform) the learned responses - learning that occurs but is not exhibited until there is reinforcement or an incentive to do so
What did Watson do?
Little Albert Experiment (classical conditioning - fears are not innate and can be learned) Rat was presented to Albert and showed no fear --> after presenting rat to Albert, Watson bangs a steel rod with a hammer (UCS) for fear (UCR) --> during conditioning, stimuli of the rat and the loud noise were presented together several times --> Watson present the rat without the bang --> Albert begins to whimper and cry (white rat - CS; fear after rat- CR) --> same response is generalized with furry items *emotional responses can be learned*

Adult stage?
Postformal thought: Understanding that knowledge is relative, not absolute; there are far more shades of gray than there are clear dichotomies of knowledge. Accepting that the world (physical and mental) is filled with contradictions: inconsistent information can exist side by side. Attempting to integrate the contradictions into some larger understanding.
What is the preoperational stage?
Preschoolers use their capacity for symbolic thought to develop language, engage in pretend play, and solve problems. But their thinking is not yet logical They are egocentric (unable to take others' perspectives) and are easily fooled by perceptions, failing conservation problems because they cannot rely on logical operations.
What is equipotent?
Principles of learning should apply across different behaviors and across different species ("organisms")

The ability to use one sensory modality to identify a stimulus or a pattern of stimuli already familiar through another modality - developed around 3-6 months
What is spontaneous recovery?
The reappearance of an extinguished response after a rest period
What is transduction? Related to?
The conversion of one form of energy to another/process that converts a sensory signal to an electrical signal to be processed in a specialized area in the brain - changing, encoding, or transducing that energy into neural signals *sensation*
What is extinction?
The gradual weakening and disappearance of a learned response when it is no longer reinforced Lessening of a conditioned response - Classical: occurs when the UCS is no longer paired with the CS - Operant: occurs when behavior is no longer reinforced
What is perception?
The interpretation of sensory input - selecting, organizing, and interpreting sensory information - enables recognition and makes meaning of objects and events - based on "higher level" information (prior knowledge or experience or wiring) - making meaning *top-down processing*
What is hearing acuity?
The keenness or sharpness of hearing - is good at birth - more developed than vision - orient to soft sounds; startles & retreats from loud sounds (reflexive at birth; voluntary control at 4 months) - recognizes mother's voice - prefer relatively complex sounds
What is a sensory threshold?
The point at which low levels of stimulation can be detected - dim light being seen - faint tone being heard - slight odor being detected
What is sensation?
The process by which information is detected by the sensory receptors and transmitted to the brain/detection of physical energy from the environment by sensory receptors - Also is the starting point in perception - Based on properties of stimulus - properties of the stimulus + transduction *bottom-up processing*
What is dark adaptation ?
The process by which the eyes become more sensitive to light over time as they remain in the dark/process in which the eyes adapt to darkness and become more sensitive to the low level of light available - occurs more slowly in older individuals than in younger ones - less sensitive/glare
What is assimilation?
The process by which we interpret new experiences in terms of existing schemes or cognitive structures. - Thus, if you already have a scheme that mentally represents your knowledge of dogs, you may label this new beast "doggie."
What is negative reinforcement?
The process in operant conditioning in which a response is strengthened or made more probable when its consequence is the removal of an unpleasant stimulus from the situation (taking something away to increase behavior - something you will be glad is gone) - alarm goes off, pressing the snooze button, alarm noise stops
What is negative punishment?
The process in operant conditioning in which a response is weakened or made less probable when its consequence is the removal of a pleasant stimulus from the stimulus (taking something away to decrease behavior - you will be sorry it is gone) - Getting in a fight with sibling over toy, the mother take the toy away
What is positive reinforcement?
The process in operant conditioning whereby a response is strengthened when its consequence is a pleasant event (applying something increase behavior - something that you like) - candy, food
What is positive punishment?
The process in operant conditioning whereby a response is strengthened when its consequence is an unpleasant event (applying something to decrease behavior - something you don't like) - late to work, driving over the speed limit, gets pulled over and receives a ticket
What is bottom-up processing?
The process in which sensation is stimulated before the brain is active in decision-making - pressure waves of sound, temperature differences (heat, cold), chemical molecules for smell, wavelengths of light *sensory information/body response --> emotion --> brain/thoughts/beliefs
What is top-down processing?
The process in which the brain makes use of information that has already been brought into the brain by one or more sensory systems - rules the brain to interpret sensory information The Gestalt - the "percept" - a unified whole - things being grouped perceptually because the stimuli occur close to one another in time and space - ex: leaves and branches merging into trees, and trees merging into forests
What is accommodation?
The process of modifying existing schemes to incorporate or adapt to new experiences - Piaget's cognitive development theory - Perhaps you will need to invent a new name for this animal (dog) or ask what it is and revise your concept of four-legged animals accordingly
What is A-not-B error?
The surprising tendency of 8- to 12-month-olds to search for an object in the place where they last found it (A) rather than in its new hiding place (B) is called the A-not-B error. The likelihood of infants making the A-not-B error increases with lengthier delays between hiding and searching and with the number of trials in which the object is found in spot A (Marcovitch & Zelazo, 1999).
What is size constancy?
The tendency to perceive an object as the same size despite changes in its distance from the eyes - an object keeps its same size no matter its distance from our eyes - change in size of image on retina is cue to depth - visual cliff experiment
What is a unconditioned response?
The unlearned response elicited by an unconditioned stimulus/natural response
Critiques on Piaget?
Themes are correct Sequence of events are correct Order develops roughly the same across cultures Age varies greatly Gradual change Context specific
What is constructivism?
Theory that children actively construct new ideas of the world based on their experiences - the position taken by Piaget and other that humans actively create their own understanding of the world from their experiences, as opposed to being born with innate ideas or being programmed by the environment
What is true object permanence?
This is the fundamental understanding that objects continue to exist—they are permanent—when they are no longer visible or otherwise detect- able to the senses. It probably does not occur to you to wonder whether your coat is still in the closet after you shut the closet door
What is "out of Sight, out of mind"?
Up through roughly 4-8 months, it is "out of sight, out of mind"; infants will not search for a toy if it is covered with a cloth or screen. By substage 4 (8-12 months), they master that trick but still rely on their perceptions and actions to "know" an object (Piaget, 1952).
How do babies react to sensory integration?
Vision --> sound - looking in the direction of a sound they hear Touch --> vision - infants expecting to feel objects they can see and are frustrated by a visual illusion that looks like a graspable object, but proves to be nothing but when they reach for it
What is classical/associative conditioning?
Watson - behaviorism: Believed that conclusions about human development and functioning should be based on observations of overt behavior rather than on speculations about unobservable cognitive and emotional processes - Classical conditioning: a simple form of learning in which a stimulus that initially had no effect on the individual comes to elicit a response through its association with a stimulus that already elicits the response - we learn associations b/w events, anticipate important events - stimulus happens first and ELICITS the response; behavior then follows - Like John Locke
What is relativism?
What is right for you
What is generalization?
When stimuli that are similar to the CS evokes some level of the CR
What is preferential looking/visual preference method?
When two objects are presented together and there is a longer looking time to the "new/different" one - in cross-model matching, we look at the one that we have already experienced - length of time looking *baby will look at the UNSCRAMBLED face*
What can newborns smell?
Yes
Does early experience affect later taste preference?
Yes - babies that had a greater exposure to a variety of flavors during infancy may lead to a more adventurous eater later on - early experiences with different flavors also extend to the prenatal period and exposure to different chemicals in the amniotic fluid *cannot discount genetic predisposition!*
Can babies hear before birth?
Yes; fetuses can hear some things outside of the womb 3 months before birth
