Behavior modification is a therapeutic technique based on operant conditioning that uses reinforcement and punishment to modify behavior by rewarding desired behaviors and discouraging undesirable ones. It has roots in classical conditioning and is used to treat various disorders and problems by conditioning behaviors through a system of rewards and consequences. Behavior modification techniques for ADHD involve reinforcing positive behaviors, punishing negative ones, and breaking behaviors down into smaller steps to shape behavior through reinforcement.
Behavior Modification for the classroom, based on Cliff Madsen's excellent book "Teaching/Discipline: A Positive Approach for Educational Development."
Behavior modification is the systematic application of learning principles and techniques to assess and improve covert and overt behaviors. It is based on classical and operant conditioning. There are several stages including identifying the target behavior, developing a new behavior to replace it, strengthening the new behavior, and maintaining it over time. Common techniques include positive and negative reinforcement, punishment, modeling, shaping successive approximations, and systematic desensitization. The goal is to help individuals develop desirable behaviors and reduce undesirable ones to better function in society.
Management of Learning Disability in children is to be made a priority in all our educational endeavours. Children achieving academical performance matching to their intellectual capacities are sometimes thwarted by LD. Find out the cause for every undesired behaviour of our children and we have to help them overcome it. It's our duty. It's required to build up a satisfied society.
Behavior and its modification techniquesRangarajan S
This document provides an overview of techniques for modifying human behavior. It discusses several factors that influence behavior, including culture, attitudes, emotions, values, and authority. It also outlines various theoretical approaches to understanding behavior, such as psychodynamic, humanistic, behavioral, cognitive, and biological approaches. Finally, it describes several social modification techniques including positive and negative reinforcement, punishment, meditation, cognitive behavioral therapy, and more. The overall document aims to understand why people behave the way they do and how problem behaviors can be addressed.
Modeling is an instructional strategy where the teacher demonstrates a new concept for students to observe and learn. The teacher breaks down tasks into specific steps, demonstrating each step multiple times while verbally explaining the process. According to learning theorist Albert Bandura, modeling is an effective way for students to form ideas of how to perform new behaviors by observing others. When using modeling, teachers describe skills, break them into learnable parts, demonstrate techniques, engage students, and check for understanding. Modeling engages different types of learners both visually and auditorily. While modeling takes time, it allows students to successfully complete tasks independently in the long run.
Organizational behavior modification (OB mod) applies reinforcement theory to motivate people in organizational settings. The reinforcement theory suggests that behavior is determined by its consequences: behaviors followed by pleasant consequences are likely to be repeated, while unpleasant consequences reduce repetition. OB mod involves identifying a target behavior, establishing a baseline, analyzing antecedents and consequences, intervening with reinforcement techniques like positive reinforcement, negative reinforcement, and punishment, and evaluating the intervention's effectiveness in changing behaviors. When applied successfully, OB mod can motivate improved performance, but it risks failure if not implemented properly.
Shaping is a technique used to establish new behaviors through reinforcement of successive approximations. It involves defining a target behavior and breaking it down into gradual steps that reinforce closer approximations over time. Shaping is commonly used to train animals and rehabilitate human behaviors. Examples of how it is applied include teaching patients to increase time between bathroom visits or training an old man to walk using parallel bars in gradual steps from sitting to taking multiple steps of support. Guidelines for effective shaping specify selecting a desired behavior and reinforcer, then reinforcing mastery of each step before moving to the next approximation.

The document discusses cognitive behavior modification developed by Donald Meichenbaum. It outlines the principles of cognitive therapy, including that it is based on a cognitive model of emotional disorders and uses a Socratic method in collaborative effort between therapist and patient. It provides a biography of Donald Meichenbaum and describes his approach of cognitive behavior modification, which focuses on understanding thoughts, feelings, and behavior and their impact, as well as creating awareness of self-talk.
Habits are formed by repeating actions over time. Forming new habits is difficult because transitioning away from old, comfortable habits causes anxiety. Our default eating habits, formed from psychological connections between cues and food, are hard to resist when stressed. Behavior modification aims to break these connections by identifying triggers for overeating and making a plan to avoid triggers or change routines. This includes eating slowly away from distractions, using smaller plates, and keeping healthy snacks available instead of leftovers.
This presentation discusses behaviour management and organizational behaviour management (OBM). It introduces behaviour management as focusing on maintaining order, while behaviour modification aims to change behaviour. OBM applies psychological principles and experimental analysis of behaviour to improve individual and group performance in organizations. OBM was first popularized by Dr. Alyce Dickinson, and the first graduate program was offered at Western Michigan University under Dr. Dick Malott. OBM interventions can increase productivity, billable hours, and effective pay systems in various workplace settings.
Modification through teaching thinking and problem solving skillsFranz Dalluay
The document discusses modifying student learning through teaching critical thinking, problem-solving, and dimensions of learning. It defines critical thinking as careful consideration of beliefs and knowledge. Problem-solving is developing skills to solve immediate problems. Dimensions of learning include positive attitudes, acquiring and integrating knowledge, extending knowledge through reasoning processes, and using knowledge meaningfully. The goal is developing productive habits of independent learning.
There are four main types of behavior measurement: frequency/event recording which counts behaviors, duration recording which tracks time spent in behaviors, interval recording which estimates behaviors over time intervals, and time sampling which observes behaviors at specific times. These methods are used to systematically collect data on behaviors and determine how often, long, or what percentage of time behaviors occur.

Mahmood Qasim Slides on Motivation for Organizational Behaviour StudentsMahmood Qasim
1. Motivation refers to the persistent effort directed towards a goal.
2. There are three classifications of motives - primary/physiological motives like food and sex, secondary/non-physiological motives like curiosity and affection, and tertiary/learned motives like power and achievement.
3. Content theories of work motivation include Maslow's hierarchy of needs, Herzberg's two-factor theory, and Alderfer's ERG theory, which link motivation to intrinsic and extrinsic rewards. Process theories include Vroom's expectancy theory and Locke and Latham's goal-setting theory.
Engr. Asim Mahmood is an electrical engineer with over 6 years of experience seeking a position in the United Arab Emirates. He has experience managing electrical design and infrastructure projects for housing schemes, commercial centers, and grid stations in Pakistan. His experience includes project planning, scheduling, design, tendering, execution, and management. He is proficient in electrical engineering software like AutoCAD, Primavera P6, and Feeder Analysis.
1) Expectancy theory proposes that motivation is highest when workers believe high effort will lead to high performance and high performance will lead to desired rewards. However, the theory may not account for situations where rewards like promotions require relocation away from family.
2) Observational learning theory suggests people learn new behaviors by watching others, and behaviors are strengthened through reinforcement. Positive reinforcement increases behavior frequency while negative reinforcement decreases it.
3) Goal setting theory claims assigning specific, difficult goals improves performance more than vague goals like "do your best." Goals direct attention and effort but individual goals may conflict with organizational goals.
Cognitive Behavior Modification was developed by Donald Meichenbaum, who believed that an individual's behavior is influenced by cognitive events and that changing those events can change behavior. It combines cognitive and behavioral principles to shape desired behaviors. The purpose is to teach self-monitoring, problem solving, and self-control to address issues like anxiety, depression, and social skills deficits. An example is using a problem-solving scale and diary to help a student with Asperger's improve his social greetings.
The document discusses organizational behavior modification (OBM) and job design. It defines OBM as the application of operant conditioning theory to manage workplace behavior. Key aspects of OBM include identifying desired behaviors, measuring current performance, analyzing incentives, and selecting intervention strategies. The document also examines different approaches to job design like classical and scientific management that focus on specialization and division of labor. It notes potential issues like monotony that these can create. Alternative models like job enrichment aim to make jobs more interesting through variety, identity, autonomy and feedback.
Impact of Fairness of Performance Appraisal System on Employee MotivationRajat Mittal
This presentation is about the impact of perceived fairness on the motivation of employees. There are two variables that I took to prove the hypothesis via a survey that grabbed data from about 100 respondents.
Biofeedback is a technique that uses instruments to monitor and provide feedback on physiological functions like heart rate, muscle tension, and brain wave activity. This feedback allows people to learn how to control these normally involuntary bodily functions. During biofeedback therapy, electrodes attach to the skin and send signals to a monitor displaying the physiological activity. As a person relaxes muscles or slows their heart rate, they receive immediate feedback. Common uses of biofeedback include treating headaches, anxiety, urinary incontinence, chronic pain, and high blood pressure by helping people gain awareness and control over stress responses in their body.
Reinforcement is any stimulus that strengthens or maintains a behavior when added or removed contingent on that behavior. There are two types of reinforcement: positive reinforcement, which involves adding a stimulus, and negative reinforcement, which involves removing a stimulus. Choosing an effective reinforcer depends on individual preferences and motivational factors like deprivation and satiation. Conditioned reinforcers can also be used by pairing them with primary reinforcers. Intermittent reinforcement, where reinforcement is given inconsistently, tends to be the most effective schedule of reinforcement at maintaining behaviors.
This document discusses different types of questions that can be used in questionnaires and surveys, including open-ended questions, fixed alternative questions, Likert-type scaling questions, and semantic differentials. It also covers considerations for survey administration such as question order effects, sensitive questions, response rates, and biases from different administration methods like face-to-face, telephone, mail, and computer surveys. The overall topic is methods for developing and administering effective questionnaires and surveys in developmental research.
This document discusses ethics in developmental research. It outlines the rights of both scientists and subjects. For subjects, it discusses the rights to not be harmed, to learn, and to experience discomfort only with consent. It also discusses how to protect subjects through voluntary participation, informed consent, privacy, and oversight from Institutional Review Boards. The document notes some past unethical experiments and debates issues like deception, debriefing, and the study of nonhuman subjects.
Small N research involves studying individual subjects to gain a deeper understanding of individual differences compared to group analysis. It uses experimental single-subject designs where the subject acts as their own control to establish a pattern of behavior and observe how that pattern changes when an intervention is introduced. Common small N designs include the simple AB design with a baseline and intervention phase, reversal designs like ABA to introduce baseline periods again, and multiple baseline designs that stagger the introduction of an intervention across subjects to control for external factors.

Common small N designs include the simple AB design with a baseline and intervention phase, reversal designs like ABA to introduce baseline periods again, and multiple baseline designs that stagger the introduction of an intervention across subjects to control for external factors.
This document discusses various quasi-experimental research methods, including archival studies, time series designs, single group pre-post tests, interrupted time series, multiple time series, cohort designs, ex-post facto designs, correlational designs, and naturalistic studies. Quasi-experimental designs aim to detect effects but have lower internal validity than true experiments. They also have limitations in determining causality due to the lack of random assignment to conditions. The document provides examples and explanations of these different quasi-experimental research methods.
This document discusses issues that can impact experimental validity in ecological research, including:
1) Bias from experimenters that can influence data collection and interactions with subjects. Multiple observers and operational definitions can help address this.
2) Subject factors like the Hawthorne effect and demand characteristics that influence participant behavior and threaten validity. Blinding techniques and deception can help control for these influences.
3) Cultural biases from the experimenters' perspective that fail to account for diversity among subjects. Including diverse participants is important to address this.
This document discusses within-groups or repeated measures designs. In within-groups designs, the same group of participants receives all levels of the independent variable. The key advantages are that all groups are equal at the beginning and the design is very sensitive to changes. Disadvantages include potential carryover effects and sensitivity to time variables like practice and fatigue. Counterbalancing techniques like Latin squares can help control for order effects. Mixed designs combine within- and between-groups approaches to rule out carryover effects while maintaining control. Matched subjects designs aim to reduce error variance by matching and randomly assigning participants.
This document discusses control in developmental research methods. It explains that control is established through careful selection of participants and random assignment to conditions. Random assignment balances any differences between groups to minimize confounding variables. True experiments use both random selection and assignment to control for threats to internal validity like history, maturation, and testing effects. Different experimental designs, like the Solomon four-group design, allow researchers to rule out additional validity threats.
psyc 321_06 threats to validity and controlRyan Sain
The document discusses testing hypotheses in developmental research methods. It explains that there are two types of variation: systematic and unsystematic. Systematic variation can come from the independent variable or from confounding variables. There are also two types of errors in hypothesis testing: type I errors in which the null hypothesis is falsely rejected, and type II errors in which it is falsely retained. Various threats to internal validity are outlined, including history, maturation, instrumentation, selection, testing effects like pretest sensitization, and mortality. Ways to control for threats include random assignment, pilot studies, blinding subjects, using distracter items, and standardizing conditions.
This document discusses numerical description in developmental research methods. It describes different types of scales used to measure variables, including nominal, ordinal, interval, and ratio scales. It also discusses distributions, measures of central tendency (mean, median, mode), variation (range, variance, standard deviation), standard scores, correlation, and examples of positive, negative and no correlation.
This document discusses the traits of effective hypotheses for developmental research. Hypotheses should be testable using available technology and methods of measurement. They should also be concrete by including operational definitions that allow for measurement. The document contrasts inductive reasoning, where hypotheses are formed based on observations and evidence, with deductive reasoning, where a theory is used to predict observations and hypotheses. Effective hypotheses can come from existing problems, research, theories, or anywhere.
This document discusses several key methods of science: naturalistic observation which involves non-intrusively observing populations without influencing them; correlational approaches which relate variables mathematically without implying causation; experimental methods which test hypotheses using experimental and control groups; and operational definitions which clearly define variables. It also discusses independent and dependent variables, confounds, validity, reliability, and the scientific attitude which values falsification, testability, skepticism, and parsimony.
This document discusses different aspects of science as a way of knowing. It explains that science involves observing phenomena to develop facts, and emphasizes doubt and questioning existing beliefs. While science is a powerful way to evaluate knowledge, it also discusses other ways of knowing like tenacity, authority, reason, and common sense. The document then outlines different scientific approaches like naturalistic observation, correlation, experimentation, post-hoc analysis, and qualitative and quantitative methods. Overall, it provides an overview of what science is and different methodologies used.
324 12 3 special topics tool use languageRyan Sain
Crows in New Caledonia were observed using tools to obtain food in ways greater than chance would predict, such as using sticks of varying lengths to reach food in tubes or bending metal strips to form hooks. While tool use could be explained by reinforcement or social learning, the crows were also able to fabricate tools on their own, suggesting an innate predisposition. Studies of primates and birds provide evidence of complex cognition and intelligence in non-human animals, sparking research on comparative cognition and questions around the origins and uniqueness of human language.
This document discusses timing in human learning. It defines timing as identifying when time has passed and responding differently. It describes techniques for studying timing, including duration estimation tasks and peak procedures. The peak procedure demonstrates how introducing a break in the stimulus shifts the peak of responding. Finally, the document outlines cognitive and behavioral theories of timing, such as scalar expectancy theory involving a pacemaker, switch and accumulator, and theories involving adjunctive waiting behaviors.
324 12 part 1 special topics food cachingRyan Sain
The document discusses food caching behavior in Clark's nutcracker birds. The birds store over 33,000 seeds in thousands of caches and are able to recover the caches in the winter. Food caching is only useful if the birds can remember where the caches are located. Research shows the birds do not search randomly or rely on typical locations, smells, or visual cues when recovering caches. Their caching and recovery abilities suggest the birds may have episodic memory, allowing them to remember detailed episodes of what items were cached, where, and when.
This document discusses observational learning, which is a change in behavior that occurs due to observing and watching the behavior of others. It describes classical conditioning studies where observers showed conditioning responses after watching a model receive shocks or eye blink conditioning. The document also discusses operant observational learning studies using monkeys and cats. It reviews factors that influence observational learning like the characteristics of the model and consequences received by the model. Finally, it briefly discusses theories of observational learning like social cognitive theory and Miller-Dollard modeling.
This document discusses discriminated avoidance learning in humans and animals. It describes how a warning signal prompts an avoidance response to prevent or remove an aversive stimulus. The dominant two-process theory explains that classical conditioning creates a fear response to the warning signal, and operant conditioning reinforces the avoidance response because it reduces this fear. The avoidance response is maintained because it allows escape from the conditioned fear response, not because it directly prevents the aversive stimulus.
The document discusses different aspects of extinction in human learning, including renewal where a response can reemerge in a new context, reinstatement where presenting the unconditioned stimulus can cause relearning, and ways to reduce recovery of the extinguished response such as using multiple extinction trials close together or presenting extinction cues in different contexts. It also notes that extinction is not permanent and does not completely erase the association between the conditioned and unconditioned stimuli.
The document discusses stimulus control and generalization in human learning. It describes how training with a specific stimulus can result in responding to similar but different stimuli, known as stimulus generalization. The strength of responding typically follows a normal curve, with strongest responding to the original trained stimulus and decreasing response strength as the stimuli vary further from the training stimulus. An example of semantic generalization is given where words paired with snacks come to elicit salivation in response to synonyms and homophones of the original words.

This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.
