  • Basic Principles of Operant Conditioning: Thorndike's Law of Effect

    • Thorndike discovered that with successive trials, cats would learn from previous behavior, limit ineffective actions, and escape from the box more quickly.
    • He observed that the cats seemed to learn, from an intricate trial and error process, which actions should be continued and which actions should be abandoned; a well-practiced cat could quickly remember and reuse actions that were successful in escaping to the food reward.
    • From a young age, we learn which actions are beneficial and which are detrimental through a trial and error process.
    • As the number of trials increased, the cats were able to escape more quickly by learning.
    • Over successive trials, actions that were helpful in escaping the box and receiving the food reward were replicated and repeated at a higher rate.
  • Kohler and Insight Learning

    • This theory of learning differs from the trial-and-error ideas that were proposed before it.
    • There is no gradual shaping or trial and error involved; instead, internal organizational processes cause new behavior.
    • Initially, Sultan tried to reach the fruit with the short stick and failed.
    • and Isaac Newton's realization that a falling apple and the orbiting moon are both pulled by the same force.
    • While both insight and heuristics can be used for problem solving and information processing, a heuristic is a simplistic rule of thumb; it is habitual automatic thinking that frees us from complete and systematic processing of information.
  • Behavioral Psychology

    • Watson, Edward Lee Thorndike, and B.
    • Edward Lee Thorndike was an American psychologist whose work on animal behavior and the learning process led to the "law of effect."
    • Skinner saw human behavior as shaped by trial and error through reinforcement and punishment, without any reference to inner conflicts or perceptions.
    • In his theory, mental disorders represented maladaptive behaviors that were learned and could be unlearned through behavior modification.
    • Skinner's radical behaviorism advanced a "triple contingency" model, which explored the links between the environment, behavior, and the mind.
  • Cognitive Development in Adolescence

    • In adolescence, changes in the brain interact with experience, knowledge, and social demands and produce rapid cognitive growth.
    • An individual can solve problems through abstract concepts and utilize hypothetical and deductive reasoning.
    • Adolescents use trial and error to solve problems, and the ability to systematically solve a problem in a logical and methodical way emerges.
    • The thoughts, ideas, and concepts developed at this period of life greatly influence one's future life and play a major role in character and personality formation.
    • Processing speed improves sharply between age five and middle adolescence, levels off around age 15, and does not appear to change between late adolescence and adulthood.
  • Problem Solving

    • Our mental sets are shaped by our past experiences and habits.
    • There are many strategies that can make solving a problem easier and more efficient.
    • The most effective depends on the type of problem and the resources at hand.
    • Morphological analysis: assessing the output and interactions of an entire system.
    • Trial and error: testing possible solutions until the right one is found.
  • Accuracy vs. Precision

    • When researchers collect data, they strive for both accuracy and precision so that their data are valid and they can reduce variance in their results due to error.
    • Measurement error can occur for a variety of reasons.
    • The errors would be "systematic"  because the same amount of error would be introduced each time you weighed something.
    • However, if you and your lab mate simply overestimate or underestimate the weight each time because you are not paying attention, this would be an example of "random" error.
    • The error is random because it will vary each time due to human error.
  • Conformity

    • Both men and women will conform to current norms in order to be accepted by society and avoid social rejection.
    • This influence is primarily informational and depends on consistent adherence to a position, the degree of defection from the majority, and the status and self-confidence of the minority members.
    • Over the course of several trials, subjects were required to select the comparison line that corresponded in length to the reference line.
    • The participant and confederates were instructed to provide their answers out loud, and the confederates were told to sometimes unanimously provide a correct answer and sometimes an incorrect answer.
    • In a control group with no pressure to conform, participants had an error rate of less 1%.
  • Memory Distortions and Biases

    • Intrusion errors are frequently studied through word-list recall tests.
    • Intrusion errors can be divided into two categories.
    • The first are known as extra-list errors, which occur when incorrect and non-related items are recalled, and were not part of the word study list.
    • The second type of intrusion errors are known as intra-list errors, which consist of irrelevant recall for items that were on the word study list. 
    • Evaluate how mood, suggestion, and imagination can lead to memory errors or bias
  • Research Methods for Evaluating Treatment Efficacy

    • The therapeutic relationship is defined as the feelings and attitudes that a client and therapist have toward one another and the manner in which those feelings and attitudes are expressed.
    • Quantitative methods include randomly controlled clinical trials, correlational studies over the course of counseling, and laboratory studies about specific counseling processes and outcome variables.
    • A randomized controlled trial (RCT) is a type of scientific (often medical) experiment, where the people being studied are randomly allocated to one or another of the different treatments under study.
    • The RCT is often considered the gold standard for a clinical trial.
    • In a randomized controlled trial, people are randomly assigned to different groups that are receiving different treatment or no treatment at all, in order to study the effects of various treatment interventions.
  • Specific Learning Disorder

    • Individuals with dysgraphia typically show multiple writing-related deficiencies, such as grammatical and punctuation errors within sentences, poor paragraph organization, multiple spelling errors, and excessively poor penmanship.
    • problems during pregnancy and birth.
    • Depending on the type and severity of their disability, interventions and technology may be used to help the individual learn strategies that will foster future success.
    • School psychologists and other qualified professionals often help design and manage such interventions.
    • Dysgraphia is often characterized by grammatical and punctuation errors within sentences, poor paragraph organization, multiple spelling errors, and excessively poor penmanship.
