    Study Notes

    Psychoanalytic Perspective

    • Proposed by Sigmund Freud, an Austrian physician
    • Focused on unconscious factors, such as drives and conflicts stemming from childhood, that impact development and behavior
    • Contributed to the understanding of the unconscious mind
    • Influenced by Neo-Freudians like Carl Jung and Alfred Adler
    • Continues to be influential in psychology today

    Behaviorist Perspective

    • Focused on studying observable actions, in contrast to the psychoanalytic perspective
    • Founded by John Watson, who built upon the work of Ivan Pavlov, focusing on classical conditioning
    • B.F. Skinner studied the impact of reinforcement and punishment on behavior, focusing on operant conditioning
    • Emphasized the scientific study of behavior
    • Remains critical in understanding learning, personality, and psychological disorders

    Humanistic Perspective

    • Emerged as a response to the limitations of the psychoanalytic and behaviorist perspectives
    • Takes a holistic approach to individuals, focusing on the higher aspects of human nature
    • Key figures: Abraham Maslow and Carl Rogers
    • Emphasized self-actualization and unconditional positive regard
    • Plays a significant role in understanding personality and treating psychological disorders

    Scientific Method

    • Focuses on testable explanations for phenomena called hypotheses
    • The alternative hypothesis predicts a relationship or difference between variables
    • The null hypothesis states that there is no significant relationship or difference between variables
    • Independent variable: Manipulated by the experimenter
    • Dependent variable: The outcome measured by the experimenter

    Types of Studies

    • Correlational studies: Describe the relationship between variables but cannot demonstrate cause and effect
    • Experimental studies: Manipulate the independent variable to determine its impact on the dependent variable, demonstrating cause and effect

    Results and Conclusions

    • Placebo: An inactive substance or sham procedure used as a comparison to a treatment of interest
    • Placebo effect: A change in a recipient due to their expectation of the treatment, even if it is placebo
    • Reliability: The consistency of an experiment or measure in producing similar results
    • Validity: The accuracy of an experiment or measure
      • Internal Validity: The extent to which a measure or experiment produces a true result
      • External Validity: The extent to which a study can be generalized to real-life situations

    Ethical Considerations

    • Ethical research protects vulnerable populations, minimizes risks, maintains confidentiality, and respects participants' rights
    • Informed consent: The process of informing participants about the study, its risks, and their rights, allowing for informed decision-making

    Descriptive Statistics

    • Measures of central tendency: Mean, median, mode
      • Mean: The average data point, calculated by summing data points and dividing by the number of data points
      • Median: The middle value when data points are ordered numerically
      • Mode: The most frequently occurring data point
    • Measures of variation: Range
      • Range: The difference between the lowest and highest data points

    Inferential Statistics

    • Pearson correlation coefficient (r): Describes the linear relationship between two variables
      • Ranges from -1 to 1, indicating the direction and strength of the relationship
      • Positive correlation: both variables increase or decrease together
      • Negative correlation: as one variable increases, the other decreases
      • Zero correlation: No linear relationship between variables
    • Correlation does not imply causation

    Psychoanalytic Perspective

    • Sigmund Freud developed the psychoanalytic approach to treat patients with psychological problems.
    • Freud proposed the concept of the unconscious mind, which influences human development and behavior.
    • Freud's theories focus on unconscious drives and conflicts stemming from childhood.
    • The psychoanalytic approach continues to influence psychology today.
    • Neo-Freudians, such as Carl Jung and Alfred Adler, expanded upon Freud's ideas.

    Behaviorist Perspective

    • The behaviorist perspective emerged in the early 1900s, focusing on observable actions.
    • John Watson, considered the founder of behaviorism, studied classically conditioned fear.
    • B.F. Skinner studied the impact of reinforcement and punishment on behavior.
    • The behaviorist perspective emphasizes the scientific study of learning, personality, and psychological disorders.

    Humanistic Perspective

    • The humanistic perspective arose as a response to the perceived pessimism and mechanistic views of the psychoanalytic and behaviorist approaches.
    • It emphasizes the holistic approach to the individual and focuses on the higher aspects of human nature.
    • Abraham Maslow proposed the hierarchy of needs, with self-actualization as the highest level.
    • Carl Rogers highlighted the importance of unconditional positive regard in individual growth.

    The Scientific Method

    • Psychology is the scientific study of mind and behavior.
    • A hypothesis is a testable explanation for a phenomenon.
    • The alternative hypothesis suggests a significant relationship or difference exists between variables.
    • The null hypothesis states that there is no significant difference or relationship between variables.

    Variables

    • In experiments, the independent variable is manipulated to determine its impact on the dependent variable.
    • The dependent variable is the outcome being measured.

    Types of Studies

    • Correlational studies describe relationships between variables, but cannot demonstrate cause-and-effect.
    • Experimental studies manipulate the independent variable to determine its impact on the dependent variable, demonstrating cause-and-effect.

    Results and Conclusions

    • Placebos are inactive substances or sham procedures used as comparisons in experiments.
    • The placebo effect occurs when a person experiences a change due to their expectations about the intervention.
    • Reliability refers to the consistency of an experiment or measure in producing similar results.
    • Validity refers to the accuracy of a study or measure.
    • Internal validity assesses whether a measure correctly measures what it intended to.
    • External validity, or generalizability, refers to the applicability of study results to real-life situations.

    Ethical Considerations

    • Ethical research protects vulnerable populations, minimizes risks, maximizes benefits, upholds confidentiality, and respects participant rights.
    • Ethics committees review research involving human and animal subjects.
    • Informed consent involves informing potential participants about the study, risks, and rights, allowing for voluntary participation.

    Descriptive Statistics

    • Descriptive statistics describe data sets using measures of central tendency and variation.
    • Mean represents the average data point.
    • Median represents the middle value when data points are arranged numerically.
    • Mode represents the most frequently occurring data point.
    • Range represents the difference between the lowest and highest data points.

    Inferential Statistics

    • Inferential statistics are used to draw conclusions that extend beyond the sample data set.
    • The Pearson correlation coefficient r describes the linear relationship between two variables.
    • The r-value ranges from -1 to 1, indicating the direction (positive or negative) and strength of the relationship.
    • A positive correlation indicates both variables increase or decrease together.
    • A negative correlation indicates as one variable increases, the other decreases.
    • A zero correlation indicates no linear relationship between variables.
    • Correlation does not imply causation.
