Ancient history of abnormal psychology
Ancient societies often attributed abnormal behavior to demonic possession or anger from the gods. Exorcisms were a common treatment method. Hippocrates was influential in arguing for natural, biological causes of mental disorders rather than supernatural ones. He categorized disorders into mania, melancholy, and phrenitis and emphasized clinical observation and heredity. Later Greek and Roman physicians and philosophers like Plato and Aristotle further studied abnormal psychology concepts, though their work was sometimes lost to popular superstition.

Ethics
If performing a PET scan on a 14 year old girl, three key ethical concerns would need to be considered:
1) Informed consent - as the girl is a minor, consent from her legal guardian would need to be obtained. They would need to be informed of the nature and purpose of the scan.
2) Confidentiality - the girl's privacy and confidentiality of any test results or data collected must be ensured, as explained to her guardian prior to the scan.
3) Withdrawal rights - it must be made clear to the girl's guardian that she has the right to withdraw from the scan at any time if she wishes, for any reason.

Research methods in psychology 1
This document discusses the key steps in the research process. It begins with identifying a broad topic of interest and narrowing it down to a specific research problem. The researcher then develops a theoretical framework and hypotheses. Next, they design their research with a methodology like surveys, experiments, or case studies. Data is collected and analyzed to test the hypotheses. Finally, results are reported and can inform managerial decision making. The overall process is iterative, with preliminary research informing problem definition and hypothesis generation before data collection and analysis provide answers.
Attention in cognitive Psychology
The document discusses different aspects of attention. It defines attention as concentrating the mind on one task and withdrawing from others. There are two types of attention discussed - selective attention which involves focusing on one stimulus while ignoring others, and divided attention which involves sharing cognitive resources between two or more stimuli. Studies on selective and divided attention show that simultaneous performance across tasks is poor but improves with practice. Sustained attention refers to attending to stimuli over prolonged periods and can deteriorate due to fatigue. Automaticity develops from repetition and frees up cognitive resources.
Research Methods in Psychology
The document provides an overview of psychological research methods. It defines research as systematic inquiry aimed at understanding human behavior and mental processes. Various research methods are described, including experimental, quasi-experimental, and non-experimental designs. Key aspects of the research process like developing hypotheses, collecting both qualitative and quantitative data, ensuring reliability and validity, and addressing ethical considerations are summarized.
Psychophysics
There are three main theories discussed in the document for relating physical properties to psychological sensation: Signal Detection Theory, Weber and Weber-Fechner Law, and Steven's Power Law. Signal Detection Theory examines sensitivity to signals and incorporates concepts like the receiver operating characteristic curve and d-prime. Weber and Weber-Fechner Law propose that just noticeable differences are proportional to stimulus intensity based on Weber's fraction. Steven's Power Law suggests people can quantify sensation in equal psychological units.
Reasoning
Reasoning can be deductive or inductive. Deductive reasoning moves from general premises to specific conclusions, while inductive reasoning moves from specific observations to broader generalizations. There are five types of inductive reasoning: example, causal, sign, comparison, and reasoning from authority. Each type uses examples, causes and effects, relationships between signs and what they indicate, comparisons between analogous cases, or credible sources to form general conclusions.

Sensation & Perception
The document discusses the key concepts of sensation and perception in psychology. Sensation is the detection and encoding of physical stimuli by the senses, while perception involves interpreting and making meaning from sensations based on experience. It describes the different senses like vision, hearing, touch, smell and taste. For vision it explains how light is transduced by the eyes and processed in the brain. For hearing it discusses sound waves and processing in the brain. It also covers concepts like sensory adaptation, perceptual constancy and how assumptions and context can influence perception.
Motivation and Emotion
This document provides an overview of different theories of motivation and emotion. It discusses drive reduction theory, incentive theory, arousal theory, and Maslow's hierarchy of needs. It also covers topics like achievement motivation, intrinsic vs extrinsic motivation, emotions, and stress response. The document aims to describe key concepts and theories related to motivation and emotion.
Lesson 13 insight and latent learning
The document discusses several concepts from psychology including factors that influence imitation, insight learning, latent learning, and Tolman's experiments with rats in mazes. It explains that insight learning involves finally solving a problem through mental manipulation, like Kohler's experiment where a monkey used two sticks together to reach food. Latent learning is learning that occurs without reinforcement, like Tolman found rats formed a cognitive map of a maze even without reward.
Psychological approaches and assumptions
This document outlines five approaches to understanding behavior: the cognitive approach, which focuses on internal mental processes like memory and perception; the social approach, which examines how people influence each other's behavior; the learning approach, which looks at how behavior is learned through experience and observation; the biological approach, which considers the roles of neurochemistry, genetics, and evolution; and the computer analogy assumption of the cognitive approach, which compares the brain to an information processor.
Ethical principles in psychological research
This document discusses ethics in psychological research. It defines ethics as moral principles that govern behavior or activities. Ethics in psychology refers to correctly following rules to protect research participants from harm while respecting their rights. The American Psychological Association establishes guidelines for ethical research including obtaining informed consent, avoiding deception, protecting participants' safety, maintaining confidentiality, allowing withdrawal from studies, and debriefing participants after a study. Key ethical factors are avoiding pressure, ensuring safety, giving proper credit, and maintaining communication with participants.
Sensation & Perception PowerPoint
1. Sensation is the detection of physical stimuli by sensory receptors, while perception is the interpretation of sensory information by the brain.
2. The visual system detects color, brightness, and hue, using rods and cones in the retina to detect light, rather than functioning like a camera.
3. Gestalt principles describe how the brain organizes visual elements into meaningful patterns through principles of proximity, similarity, closure, and continuity.
Sensation and Perception
- Stimuli are detected by sense organs and transmitted as sensations. Perception involves interpreting these sensations based on prior knowledge and experience.
- Key aspects of perception include grouping elements based on principles like proximity, similarity and continuity. It also involves figure-ground perception and maintaining constancies like size, shape, color and brightness despite changes in viewing conditions.
- Sensory receptors underlie different senses like vision, hearing, touch, taste and smell. Vision involves rods and cones detecting light, while hearing codes frequencies via place and volley theories.
Psychology chapter learning presentation
1. Learning involves acquiring new knowledge, behaviors, or skills through experience. It can occur through classical conditioning, where organisms learn to associate stimuli, operant conditioning, where behavior is modified by its consequences, or cognitive learning which requires perception and understanding.
2. Major theories of learning include associative learning proposed by Aristotle and others, where events linked in time become associated; Pavlov's classical conditioning experiments; Thorndike's laws of effect and exercise; Skinner's operant conditioning research; and cognitive learning involving insight and problem solving.
3. Learning is influenced by reinforcement which increases behavior and punishment which decreases it. Theories and experiments by thinkers like Pavlov, Skinner, Bandura, and Kohler
Ethical issues in psychology
This document discusses ethical issues in psychology. It begins by defining ethics and its relationship to morality and professional codes of conduct. It then outlines several core areas of ethical issues in psychology, including resolving ethical issues, competence, human relations, privacy and confidentiality, advertising, record keeping and fees, education and training, research and publication, assessment, and therapy. Within each of these areas, it lists specific ethical principles, guidelines, and considerations. The document provides an overview of the broad scope of ethics within the field of psychology.
Memory and Models of Memory
A brief overview of memory and the most basic models of memory for my introductory psychology class.
Asch conformity experiment
Solomon Asch conducted a famous conformity experiment in the 1950s where he had participants judge which of three lines was the same length as a target line. While most of the other participants were confederates who intentionally gave the wrong answer, about 1/3 of real participants conformed at least once by giving the incorrect answer to fit in with the majority. The experiment demonstrated the powerful influence of social pressure and conformity within groups.
psychological Testing
Psychological testing involves standardized measures of mental and behavioral characteristics to assess individual differences. There are several key principles of psychological testing including standardization, objectivity, establishing norms, reliability, and validity. Tests are used to help evaluate clients, determine treatment approaches, and provide insight into patterns of relating. Common types of tests include intelligence tests, aptitude tests, achievement tests, personality tests, and neuropsychological tests. The goal of psychological assessment is to integrate information from multiple sources like tests, interviews, and records.
Research Methods in Psychology
This document discusses various research designs and methods used in psychological research. It describes how psychological research questions are developed and how theories and hypotheses guide research. Observational, experimental, correlational, longitudinal and other research designs are explained along with their strengths and limitations. Key considerations for psychological research like validity, reliability, ethics and statistical analysis are also covered.
Learning (Psychology) Lecture notes by Imran Ahmad Sajid
This document discusses different types of learning including classical conditioning, operant conditioning, and cognitive learning. Classical conditioning involves associating a neutral stimulus with an unconditioned stimulus to elicit a conditioned response. Operant conditioning is learning through reinforcement and punishment where behaviors are strengthened or weakened based on consequences. Cognitive learning focuses on mental processes like attention, retention, and motivation that underlie learning through observation and latent learning when behaviors are acquired but not demonstrated until needed.

General Psycho
General Psychology Instructor: Dan Benkendorf. Psychology is the science of behavior and mental processes. It seeks to answer questions about the relationship between the brain and behavior, the origins of personality, why people conform to social norms, and the causes of mental illness. There are several specialty areas in psychology including biological, cognitive, experimental, developmental, social, personality, health, educational, and clinical. The scientific method uses assumptions, evidence, and conclusions to describe, explain, predict, and control behaviors. Knowledge of research methods enables accurate predictions.

psychology
This document provides an overview of psychological research. It defines research as a careful, systematic study to establish facts or principles. Psychology is defined as the study of mental processes and behavior. There are three main types of psychological research: correlational research, descriptive research, and experimental research. Researchers use tools like questionnaires, interviews, observation, and checklists. The purpose of research is to describe behavior, understand why events occur, and apply knowledge to problems.
Psychology module 4
Research using scientific methods like observation, experimentation, and statistical analysis allows psychologists to learn more about human behavior in a systematic way compared to relying solely on common sense or personal experiences. Various types of research strategies have advantages and disadvantages. Experiments are the only method that can establish cause-and-effect relationships by manipulating an independent variable and observing its impact on a dependent variable. However, other observational methods like case studies and surveys provide important insights too. Researchers must consider factors like bias, random assignment, blind procedures, placebos, sample sizes, and replication to draw valid conclusions while also following ethical guidelines to protect human and animal subjects.
Basic introduction to research methods
The document outlines the scientific method used in psychology. It discusses the 5 basic steps: 1) observe phenomena, 2) formulate a question/hypothesis, 3) test predictions through research, 4) draw conclusions, and 5) evaluate results and collaborate. It also describes different types of research (descriptive, correlational, experimental) and settings (laboratory, natural observation). Experimental research involves manipulating an independent variable to measure its effect on a dependent variable, while controlling for validity, experimenter bias, participant bias, and placebo effects. Data is analyzed using descriptive and inferential statistics to determine if results support hypotheses. Ethical standards require informed consent, debriefing, confidentiality, and humane treatment of research participants.
Research Methodology
Research is defined as a systematic effort to gain new knowledge. It involves formulating a research problem, conducting a literature review, developing hypotheses, designing a study, collecting and analyzing data, and reporting findings. The goal of research is to discover answers to questions through objective and systematic methods of finding solutions.

This document provides an overview of research methods. It defines research as a systematic, empirical and critical process of inquiry aimed at increasing knowledge. Research can be classified as fundamental/basic research or applied research. The main types of research methods discussed are experimental research, which can be conducted in laboratory or field settings, and non-experimental research such as surveys, field studies, and ex-post facto research. Key characteristics of scientific research include being solvable, empirical, observable, developmental, systematic, and replicable. Factors that can threaten the internal validity of research like selection bias, history effects, and experimenter expectations are also outlined.
Basic introduction to research methods
1. Psychology uses the scientific method to conduct research in an organized and objective way to increase knowledge. The scientific method involves observing phenomena, formulating questions and hypotheses, testing predictions through research, drawing conclusions, and evaluating results.
2. There are different types of research including descriptive research using surveys and case studies, correlational research examining relationships between variables, and experimental research manipulating independent variables. Research also takes place in laboratories and natural settings.
3. Researchers analyze data using descriptive statistics to summarize results and inferential statistics to determine if findings are statistically significant. They interpret what conclusions can be drawn given the data while considering the study's limitations.

Describe the experimental, observational, survey, and case study methods of conducting
psychological research. Include a discussion of how each addresses independent, dependent, and
extraneous variables, the relative advantages and disadvantages of each method, and how (or if)
each method can be conducted in the three developmental methodologies
Solution
There are several methods that are used for reseach in psychology. These approaches vary by the
sources of information which is drawn on, how that information is sampled, and the types of
instruments that are utilized in data collection. It also depends if the methods collect qualitative
data, quantitative data or both of them.
Qualitative psychological researches are those where the research findings are not arrived at by
statistical or other quantitative procedures.Quantitative psychological research is where the
research findings result from mathematical modeling and statistical estimation or statistical
inference. Since qualitative information can be handled as such statistically, the distinction
relates to approach, rather than the topic studied.
Experimental Method
The field of psychology commonly uses experimental approaches in what is best known as
experimental psychology. Researchers design experiments to test specific hypotheses aka
deductive approach, or to evaluate functional relationships aka inductive approach. The method
of experimentation involves an experimenter changing some influence on the research subjects,
and studying the effects it produces on an expected aspect of the subjects behaviour or
experience. Other variables researchers consider in experimentation are known as the extraneous
variables, and are either controllable or confounding
Observational Methods:
Observational research is a type of non-experimental, correlational research. It involves the
researcher observing the ongoing behaviour of their subjects. There are multiple approaches of
observational research such as participant observations, non-participant observations and
naturalistic observations
Survey Method:
Most of the interviews intrude as a foreign element into thesocial setting that they describe. They
create as well as measure attitudes, they play vital role and responsibility. Though they are
limited to those who are accessible and who will cooperate, but the responses obtained are
produced in part by dimensions of individual differences irrelevantto the concerned topic under
discussion.
Case Study Method:
Normally case study is an intensive analysis of a person, group, or event that stresses
developmental factors related to the topic. Case studies may as well be descriptive or
explanatory. Explanatory case studies explore causation to figure out the underlying principles.
But there often is a debate to whether case studies count as a scientific research method or not.
Clinical psychologists use case studies most often, especially to describe abnormal events and
conditions, which are particularly .

Research is a way of gaining knowledge and finding solutions. It involves empirical investigation and corrects mistakes by experts. Research provides background information when experience or intuition may be limited. The main purposes of research are to agree with others, prove opinions, and apply the scientific method to solve problems. Research in education aims to expand knowledge and solve educational issues. The basic types of research are basic research, which adds to existing knowledge, and applied research, which provides practical solutions. Research can be qualitative, which studies topics holistically, or quantitative, which uses numerical data and focuses on a few variables. Good research questions are significant, feasible, clear, investigate relationships, and ethical.

This document outlines the steps in quantitative and qualitative research. It begins by differentiating between the two methods, noting that quantitative research uses numeric and measurable data while qualitative focuses on personal perceptions.
For quantitative research, the steps include identifying a problem, developing a hypothesis, collecting numeric data, analyzing results, and interpreting findings. For qualitative research, the process involves identifying a problem, selecting a design, collecting subjective data through interviews or observations, analyzing themes in the data, and interpreting results.
Finally, the document discusses using both methods together in a single study to gain a more comprehensive understanding of a problem. It provides examples of nursing issues that could be addressed through these research approaches.
Chapter 1 Lecture Disco 4e
