For example, if a dog is first conditioned to salivate to a bell (CS1) because it is paired with food (US), and then a light (CS2) is paired with the bell (CS1), the dog may eventually salivate to the light alone, even though the light was never directly paired with food.</p> Signup and view all the answers

What are the evolutionary advantages of classical conditioning? Explain this using taste aversion as an example.

<p>Classical conditioning has evolutionary advantages by allowing organisms to predict and prepare for significant events. Taste aversion is a prime example: if an animal eats something that makes it sick, it quickly learns to avoid that taste in the future. This helps the animal survive by preventing it from consuming harmful substances.</p> Signup and view all the answers

Describe the “little Albert" study. What does this study tell us about the development of fears and phobias?

<p>The 'Little Albert' study, conducted by John B. Watson, involved conditioning a young child to fear a white rat by pairing the rat with a loud, startling noise. The study demonstrated that fears and phobias can be learned through classical conditioning, as Albert generalized his fear to other similar stimuli, such as a white rabbit and a fur coat.</p> Signup and view all the answers

Was the "little Albert” study ethical? How could his fear have been treated?

<p>The 'Little Albert' study is considered unethical by modern standards because it caused significant distress and potential long-term harm to the child, and the fear was never properly extinguished. Albert’s fear could have potentially been treated through systematic desensitization, where he would gradually be exposed to the feared stimuli in a safe and controlled environment.</p> Signup and view all the answers

Using advertisement as an example, can classical conditioning be applied to every day life?

<p>Yes, classical conditioning is frequently used in advertising to create positive associations with products. For example, advertisers might pair a product with attractive people, pleasant music, or heartwarming scenes, so that consumers develop a positive emotional response to the product itself.</p> Signup and view all the answers

Explain Thorndike's law of effect. Use as an example his studies of cats studying puzzle boxes.

<p>Thorndike's law of effect states that behaviors followed by satisfying consequences are more likely to be repeated, while behaviors followed by unpleasant consequences are less likely to be repeated. In his studies with cats in puzzle boxes, Thorndike observed that cats learned to escape the box more quickly over time because they experienced a positive outcome (freedom and food) after performing the correct actions.</p> Signup and view all the answers

What is shaping? Describe the two principles that make shaping successful.

<p>Shaping is a process used in operant conditioning where successive approximations of a desired behavior are reinforced until the desired behavior is achieved. The two principles that make shaping successful are (1) reinforcing small steps or successive approximations toward the desired behavior and (2) not reinforcing previously achieved approximations once a new, closer approximation is achieved.</p> Signup and view all the answers

Define positive and negative reinforcement and punishment. You should be able to identify why the procedure is known as “positive” or “negative" and why it constitutes “reinforcement” or "punishment". You will need to identify examples of each.

<p>Positive Reinforcement: Adding a desirable stimulus to increase a behavior (e.g., giving a treat to a dog for sitting). Negative Reinforcement: Removing an aversive stimulus to increase a behavior (e.g., turning off an annoying alarm by pressing a button). Positive Punishment: Adding an aversive stimulus to decrease a behavior (e.g., scolding a child for misbehaving). Negative Punishment: Removing a desirable stimulus to decrease a behavior (e.g., taking away a toy from a child for fighting).</p> Signup and view all the answers

Is the use of punishment ethical? How can punishment be applied for it to be successful?

<p>The ethics of punishment are debated, as it can lead to negative side effects such as fear, anxiety, and aggression. If punishment is used, it should be applied consistently, immediately following the behavior, and paired with reinforcement of alternative, desired behaviors.</p> Signup and view all the answers

Explain the impact of schedules of reinforcement on behavior. Learn to define and signal the graph for each schedule (FI, FR, VI, and VR). Why is the schedule defined as “ratio” or “interval"? Why is it considered to be “fixed” or “variable”? You will need to identify examples of each.

<p>Schedules of reinforcement greatly impact behavior. Fixed Interval (FI): Reinforcement is given after a set amount of time has passed (e.g., a paycheck every two weeks). Fixed Ratio (FR): Reinforcement is given after a set number of responses (e.g., a bonus for every ten items sold). Variable Interval (VI): Reinforcement is given after a varying amount of time (e.g., checking email, where emails arrive at unpredictable times). Variable Ratio (VR): Reinforcement is given after a varying number of responses (e.g., gambling). Ratio schedules are based on the number of responses, while interval schedules are based on the passage of time. Fixed schedules have predictable patterns, while variable schedules are unpredictable, leading to more consistent responding.</p> Signup and view all the answers

Which schedules of reinforcement result in the most responding? Why?

<p>Variable ratio schedules typically result in the highest rates of responding because reinforcement is unpredictable, leading to a persistent and high level of behavior. The uncertainty keeps the individual engaged and motivated to continue responding.</p> Signup and view all the answers

Explain the difference between a primary and a secondary (conditioned) reinforcer.

Using behavior modification in children as an example, how should time-out be implemented for it to be successful?

<p>For time-out to be successful in behavior modification with children, it should be implemented consistently, immediately following the undesired behavior, and in a designated quiet area with minimal stimulation. The duration should be brief (e.g., one minute per year of age) and the child should be able to return to the activity once the time-out is over, without further discussion of the misbehavior.</p> Signup and view all the answers

Different schedules of reinforcement (fixed-ratio, fixed-interval, variable-ratio, variable-interval) affect the rate and pattern of responding.

Signup and view all the flashcards

Most Effective Schedule

Variable ratio schedules tend to produce the most consistent and high rates of responding because the reinforcement is unpredictable.

CS, US, CR, UR definitions

CS (Conditioned Stimulus): Originally irrelevant stimulus that, after association with an unconditioned stimulus (US), comes to trigger a conditioned response (CR). US (Unconditioned Stimulus): A stimulus that unconditionally—naturally and automatically—triggers an unconditioned response (UR). CR (Conditioned Response): A learned response to a previously neutral (but now conditioned) stimulus (CS). UR (Unconditioned Response): An unlearned, naturally occurring response (such as salivation) to an unconditioned stimulus (US) (such as food in the mouth).

Study Notes

  • Working memory encompasses a phonological loop, visuospatial sketchpad, episodic buffer, and a central executive
  • Long-term memory storage capacity is essentially limitless
  • The three primary functions of memory include encoding, storage, and retrieval
  • The physical trace of memory is known as an engram
  • An exceptionally clear recollection of an important event is a flashbulb memory
  • Egocentric bias involves recollections of the past in a self-enhancing manner
  • The tip-of-the-tongue phenomenon is also known as blocking
  • The formulation of new memories is construction, while bringing up old memories is reconstruction
  • The statement "Every good boy does fine" is an example of an acrostic, used to remember the notes E, G, B, D, and F
  • To improve short-term memory, writing about a trivial topic is beneficial
  • The self-referencing effect refers to making the material you are trying to memorize personally meaningful
  • Memory aids that help organize information for encoding are mnemonic devices
  • Memory is surprisingly malleable
  • Eyewitness testimony is prone to error
  • Memories are altered every time they are recalled
  • Imagination inflation can create false memories
  • Suggestibility can impact memory and create false memories
  • Source monitoring errors lead to incorrect memory sources
  • Forgetting is essential for efficiently using our memory system
  • Seven sins of memory include transience, absentmindedness, blocking, misattribution, suggestibility, bias, and persistence
  • Transience is accessibility of memory decreases over time
  • Absentmindedness is forgetting caused by lapses in attention
  • Misattribution is source of memory is confused
  • Bias is memories distorted by current belief system
  • Persistence is unwanted memories
  • Amnesia is the loss of long-term memory
  • Anterograde amnesia is the inability to form new memories
  • Retrograde amnesia is loss of memory for events that occurred prior to brain trauma
  • Memory consolidation occurs in the hippocampus
  • The amygdala is involved in emotional memories
  • The cerebellum is involved in implicit memories
  • Prefrontal cortex is involved in remembering semantic tasks
  • The brain constructs its own reality, which may not always match the physical universe
  • Visual perceptions, such as size, can be manipulated to trick the brain

Size Estimation

  • The size of an object is estimated based on the size of the image projected onto the retina
  • Smaller images generally imply smaller objects
  • Ceilings, as visual landmarks, help in judging size

Assumptions in Size Perception

  • The brain assumes rooms are ordinary and box-shaped
  • The brain assumes the back wall is perpendicular to the line of sight
  • The brain assumes the floor and ceiling are level and parallel

The Ames Illusion

  • The room is actually trapezoidal, not box-shaped
  • The back left corner is farther away than the right in the Ames room
  • The image appears smaller due to the increased distance in the Ames room
  • The ceiling slants downward, and the floor slants upward from left to right in the Ames room
  • The room's features are distorted to appear rectangular
  • The checkerboard pattern gets finer toward the right in the Ames room
  • Windows are resized and shaped to match the trapezoidal back wall
  • A narrow angle of view blocks cues revealing the room's true shape
  • The brain believes in a box shape because rooms usually have that shape

History of the Ames Room

  • The Ames Illusion was devised by American ophthalmologist Adelbert Ames Jr. in 1934
  • Adelbert Ames Jr. built a physical example of the Ames room in 1935

Edward Thorndike and Skill Learning

  • Edward Thorndike aimed to understand new skill acquisition
  • Thorndike created puzzle boxes requiring cats to operate latches for escape
  • While the escapes appeared ingenious, Thorndike doubted cats understood the consequences of their actions
  • Initial successful actions by cats seemed to occur randomly
  • Thorndike proposed that learning occurred through trial and error
  • Graphs measured the rate of learning in cats
  • Well-practiced cats quickly recalled actions leading to escape and reward
  • Rewarded actions became "stamped" into the mind
  • Behavior changes as a result of its consequences
  • The principle that behavior changes due to consequences is called the "law of effect"
  • The law of effect explains how wild animals develop new habits

Learning Aggressive Behaviors Through Modeling

  • The study is an early experiment about learning aggression by modeling behavior
  • Children watched a film of an adult performing aggressive acts toward an inflated doll
  • The adult model combined physical aggression with hostile verbal remarks
  • Researchers measured how much of this behavior children learned by observation
  • The level of aggression was measured using simulated targets rather than live ones
  • In the film the doll was pummeled with a mallet, flung, kicked repeatedly, thrown down, and beaten
  • Exposure to the aggressive behavior in the film increased children's attraction to guns
  • Children with no exposure to the aggressive behavior modeling showed less interest in guns
  • Children also learned and repeated the novel, hostile language used by the adult in the film
  • The children devised new ways of hitting the doll that they had not seen before
  • The objective of study was to see new aggressive acts, not just any interaction with the doll
  • The children in the control group never exhibited the novel forms of aggression shown in the film
  • In effect, the children turned the doll into a weapon of assault

Accident and Amnesia: Scott Bolan's Case

  • Scott Bolan was diagnosed with profound retrograde amnesia after an accident on December 17, 2008
  • Bolan slipped on an oily substance outside his office restroom in Tempe, Arizona
  • Post-accident, he has no memory of his life prior to the incident
  • Bolan does not remember his wife, children, career, or experiences like playing in the NFL
  • Before his accident, Bolan was the captain of the Northern Indiana University Huskies (1980-1983) and an NFL player for the New England Patriots and Cleveland Browns (1984-1986)
  • Bolan retired from the NFL due to an injury
  • He founded an aeronautical company
  • In 2008, at the age of 46, he fell and had a concussion
  • The concussion resulted in bleeding and subsequent atrophy of his right temporal lobe, and a severe case of retrograde amnesia

Initial Aftermath of Bolan's Accident

  • Immediately after the fall, Bolan mentioned "something oily" on his hands
  • He was confused, tried to get up, and subsequently lost his memory of the incident

Impact on Bolan's Family

  • Bolan's parents live in Chicago and struggle to understand the extent of his amnesia
  • Bolan feels disconnected from his parents due to his lack of intimate memories of them

Rediscovering Love and Family

  • Upon introduction in the hospital, Bolan felt an immediate bond of trust with his wife, Joan
  • At the time of the accident, his daughter was 16 and his son was 19

  • A CT scan revealed significant damage and "huge holes" in Clive's brain
  • Clive knows Deborah is his wife but does not remember their wedding
  • He retains his musical abilities, particularly piano skills, because of procedural memory
  • He remembers facts but not life events
  • Clive experiences frustration and anger because of his condition but forgets it quickly
  • He compulsively records the moment he wakes up each day in a diary
  • He crosses out previous entries because he believes he is only awake when he is writing
  • Clive often writes Deborah's name in his diary, asking her to visit, even if she has recently been there
  • Clive experiences anterograde Amnesia

Deborah Wearing's Perspective

  • Deborah has been married to Clive since 1983
  • She describes him as charismatic, intelligent, modest, sweet, and funny
  • Deborah acknowledges their marriage is unusual, but it remains a husband-and-wife relationship
  • Deborah left Clive in 1993 due to the emotional pain of his condition and moved overseas
