Psychology Chapter 6 Notes Essay Example

Psychology Chapter 6 Notes Essay Example Psychology Chapter 6 Notes Essay Psychology Chapter 6 Notes Essay Learning – long lasting change in behavior resulting from experience Classical Conditioning – a form of learning in which the first stimulus is the signal of the occurrence of the second stimulus Unconditioned stimulus (US/UCS) – the original stimulus that elicits a response Unconditioned response (UR/UCR) – the involuntary, reflexive response to unconditioned stimulus Conditioned stimulus – the stimulus associating with the original stimulus to elicit a response Conditioned response – salvation elicit from the bell (not getting there yet) Acquisition – learning is taken place once animals response to conditioned stimulus without the existence of unconditioned stimulus the animal has acquired a new behavior Delayed conditioning – the procedure in which conditioned stimulus is presented first and then the unconditioned stimulus is presented while the conditioned stimulus is still evident/continued Extinction – the process of unlearning a behavior Spontaneous Recovery – after a conditioned response has been extinguished with no further training, the response briefly reappears upon the presentation of the conditioned stimulus Generalization – the tendency in which animals response to certain stimuli that are similar the conditioned stimulus Discriminate – in which subjects can be trained to tell the difference between various stimuli Aversive conditioning – negative responses to CSs/USs Eg. Baby Albert experiment: loud noise(US), in which baby Albert fears (UR), is paired with white rat (originally US), so baby Albert then learned to be afraid of white fluffy stuff (generalization) white rat become CS; CR is the response to the white rat alone Second Order/Higher Order conditioning – when CS elicits a CR, the CS is then used as US to condition a response to a new stimulus Eg. Dog salivates when hearing bell rings. Pairing bells with flash lights or others will cause dog to salivate with flash light/ others alone. Learned taste aversion –developing aversion for a certain food/drink because you have experienced uncomfortable feelings after ingesting it. Salient – easily noticeable and therefore create a more powerful conditioned response Operant conditioning – is a sort of learning based on the association of consequences of one’s behavior Law of effect – if the consequence of a behavior is pleasant, the stimulus-response (S-R) connection will be strengthened, and the likelihood of the behavior will increase; if the consequence of a behavior is unpleasant, the stimulus-response (S-R) connection will be weakened, and the likelihood of the behavior will decrease Instrumental learning – consequence is the instrument shaping the future behaviors Skinner box – is a box that has a way/path to deliver food and a lever to press to peck in order to get food Reinforcer – for the sample above, it will be the food. It is something that reinforce/ motivate the subject to have a specific behavior Anything that makes a behavior likely to occur Reinforcement – the process of giving the reinforcer defined by its consequence Positive reinforcement: a behavior is strengthened for the addition of something pleasant Negative reinforcement: a behavior is strengthened for the removal of something unpleasant Escape learning – when one terminate an aversive stimulus Avoidance learning – enables one to avoid unpleasant stimulus altogether Punishment – unpleasant consequence that will a behavior, making a behavior less likely Shaping – a way to reinforce/speed up a behavior we desire to reach 1. Positive punishment: addition of something unpleasant to make a behavior less frequent 2. Negative punishment/ omission training: the removal of something pleasant to make a behavior less frequent Chaining – when subjects are taught to perform a number of responses successively in order to get a reward Discriminative stimulus – the stimulus that the subject is able to distinguish from Primary reinforcers – rewards such as food, water and rest; whose natural properties are reinforcing Secondary reinforcers – things we have learned to value Generalized reinforcer – money, traded for virtually anything Token economy – a system of behavior modification that can be rewarded with tokens/symbols which can be exchanged with variety of reinforcers Premack principle – a principle that states that the reinforcers are not always effective to all subjects depending on how desired and what is desired by the subject. OVERVIEW learning is different from behavior, yet changes in behavior best demonstrates learning learning must result from â€Å"experience† rather than â€Å"innate† or â€Å"biological change† CLASSICAL CONDITIONING Ivan Pavlov, Russian psychologist: discovered â€Å"a kind of† learning while studying digestion in dogs dogs pair the sounds in environment where they were fed with food, began to salivate upon hearing the sounds Pavlov deduce the â€Å"basic principles† of classical conditioning Eg. First stimulus: the sounds in the environment Second stimulus: began to salivate simply upon hearing the sounds People animals can learn to associate neutral stimuli (example: the sound) with stimuli that produce involuntary, reflexive responses (example: food) to respond to the new stimulus as they did to the old one (example: salivate) the unconditioned stimulus the food food elicits the natural and involuntary response salivate factors that affects acqu isition: 1. Repeated pairings of unconditioned stimulus with conditioned stimulus yield stronger conditioned responses 2. Order timing of conditioned stimulus and unconditioned stimulus have impact on strength of conditioning most effective conditioning present conditioned stimulus first and then to introduce the unconditioned stimulus while conditioned stimulus is still evident Less effective methods of learning 1. Trace conditioning: the presentation of conditioned stimulus, followed by a short break, followed by unconditioned stimulus 2. Simultaneous condition: where both conditioned stimulus and unconditioned stimulus are presented at the same time 3. Backward condition: Unconditioned stimulus is presented first, follow by conditioned stimulus. This method is particularly ineffective. CS no longer elicits CR classical conditioning for extinction repeatedly presenting CS without US will cause extinction people and animals will have the tendency to respond to similar conditioned stimulates, generalization~ Eg. Animals will salivate to different kinds of ringing bells to discriminate, for animals/people to tell the difference between the conditioned stimulates, the conditioned stimulates, present the specific CS with US while the other CSs with no US BIOLOGY AND CLASSICAL CONDITIONING learned taste aversions demonstrate not all US can be paired with any CSs animals humans are biologically prepared to associate strange taste with the feeling of sickness the food (CS) must be salient in order for us to avoid it sometimes taste aversions are acquired without good reason. Eg. If you are eating some mozzarella sticks a few hours before you fall ill with stomach flu, you might develop an aversion to that popular American appetizer even though it had nothing to do with your sickness OPERANT CONDITIONING Edward Thorndike: first person to research on operant conditioning Edward Thorndike states the law of effect about the pleasant consequence elicits pleasant behavior, unpleasant consequence elicits unpleasant behaviors Edward Thorndike claimed is experiment to be instrumental learning because he believes that consequence is instrumental in shaping future behaviors B. F. Skinner (another famous psychologist for this – behaviorism, area of studies) invented a contraption called Skinner box 2 kinds of reinforcement 1. Positive reinforcement: a behavior is strengthened for the addition of something pleasant 2. Negative reinforcement: a behavior is strengthened for the removal of something unpleasant B. F. Skinner eg. When the rat pushes the lever, the rat will receive its award(food) which cause the rat to push the lever more often – POSTIVE REINFORCEMENT B. F. Skinner eg. The rat hated loud noise but when the rat pushes the lever, the loud noise stops, hich cause the rat to push the lever more frequent to avoid the loud noise – NEGATIVE REINFORCEMENT the example above is also a escape learning because the rat can avoid an aversive stimulus for pressing the lever more often an avoidance learning would be when the rat runs away from the loud noise (another behavior/response) to avoid what it hated 2 types of punishment 1. Positive punishment: addition of something unpleasant to make a behavior less frequent 2. Negative punishment/ omission training: the removal of something pleasant to make a behavior less frequent Punishment versus Reinforcement punishment is operant conditioning’s version of aversive conditioning shaping helps to speed up a specific behavior we desired for rat Barnabus is asked to go through a series of veritable obstacles in order to get food as reward chaining the goal of chaining is to link a series of separate behaviors into one complex activity

Typical Course of Study for 8th Grade

Typical Course of Study for 8th Grade The final year of middle school, eighth grade is a time of transition and preparing students for high school. Eighth-grade students will spend their last year of middle school building on what they learned as sixth-  and 7th-grade students, strengthening any areas of weakness, and digging into more complex coursework as they prepare for high school. Though many will still need guidance and a source of accountability, eighth-grade students should be making the shift to self-directed, independent learning. Language Arts As in previous middle school grades, a typical course of study for eighth-grade language arts includes literature, composition, grammar, and vocabulary-building. Literary skills focus on reading comprehension and analyzing texts. In preparation for standardized testing and college entrance exams, students should practice applying their reading comprehension skills to a variety of documents.   They should be able to recognize the main idea, central theme, and supporting details. Students should have plenty of practice summarizing, comparing and contrasting, and inferring an authors meaning. Eighth-grade students should also learn to recognize and understand the uses of language such as figurative language, analogies, and allusion. Students should begin comparing and contrasting two texts that present conflicting information on the same topic. They should be able to identify the cause of the conflicts, such as contradictory or inaccurate facts or the authors opinion or bias on the subject. Provide eighth-graders with ample opportunity to practice their composition skills. They should write a variety of essays and more complex compositions including how-to, persuasive, and informational articles; poetry; short stories; and research papers. Grammar topics include correct spelling throughout the students writing; proper use of punctuation such as apostrophes, colons, semicolons, and quotes; infinitives; indefinite pronouns; and correct use of verb tense. Math There is some room for variation in eighth-grade math, particularly among homeschooled students. Some students may be ready to take Algebra I for high school credit in eighth grade, while others will prepare for the ninth grade with a prealgebra course. In most cases, a typical course of study for eighth-grade math will include algebraic and geometric concepts, along with measurements and probability. Students will learn about square roots and both rational and irrational numbers. Math concepts include finding a lines slope using the  slope-intercept formula,  understanding and evaluating functions,  parallel and perpendicular  lines, graphing, finding the area and volume of more complex geometrical shapes, and the  Pythagorean theorem.   Science Although there isnt a specific recommended course of study for eighth-grade science, students typically continue to explore earth, physical, and life science topics. Some students may take a general or physical science course for high school credit while in eighth grade. Common general science topics include the scientific method and terminology. Earth science topics include ecology and the environment, conservation, composition of the earth, oceans, atmosphere,  weather,  water and its uses, weathering and erosion, and recycling. Physical science topics include magnetism and electricity; heat and light; forces in liquids and gases; wave, mechanical, electrical, and nuclear energy;  Newtons laws of motion;  simple machines;  atoms; the  periodic table of elements;  compounds and mixtures;  and chemical changes.   Social Studies As with science, there is no specific course of study guidelines for eighth-grade social studies. A homeschool familys curriculum choices or personal preferences are usually the determining factors. An eighth-grader following a classical homeschooling style will likely study modern history.   Other standard topics for eighth-grade social studies include explorers and their discoveries, the growth and development of the United States, colonial life, the U. S. Constitution and Bill of Rights,  and the  American Civil War  and Reconstruction. Students may also study a variety of topics related to the United States such as the U.S. culture, political system, government, economic system, and geography. Health and Safety For families who have not already done so, eighth grade is an excellent time for a health and safety course. Many states homeschooling laws or umbrella schools require a health course for high school graduation, so students who are ready for a high school-level course may be able to earn credit for it in middle school.   Typical topics for a health course include personal hygiene, nutrition, exercise, first aid, sexual health, and the health risks and consequences associated with drugs, alcohol, and tobacco use.
