    Study Notes

    Scientific Approach to Research

    • The scientific approach has three main goals: description, prediction, and understanding.
    • Description involves summarizing data to make it easily understood.
    • Prediction involves using research outcomes to identify what would happen in the future.
    • Understanding involves identifying causal factors that led to research results.

    Hypothesis and Theory

    • A theory is a systematic way of organizing and explaining observations.
    • A hypothesis is a tentative belief about the relationship between two or more variables.

    Measurement in Research

    • Measurement is the process of turning an abstract concept into a numerical value.
    • Measurement can be complex and may require multiple measures to obtain information.

    Population and Sample

    • A population is a larger group of people that researchers intend to study.
    • A sample is a subgroup of the population that is representative of the population as a whole.

    Generalisability and Internal Validity

    • Generalisability refers to the ability to infer something about a larger population from the behavior of a subset of people.
    • Internal validity refers to the strength of the study design in ensuring that the procedures used to test the hypothesis are sound.

    Experimental Research

    • An experiment involves manipulating variables to observe their effects.
    • The different levels or variations of the independent variable are referred to as conditions.
    • The dependent variable is the response measured to see whether the experimental manipulation had an effect.

    Operationalisation and Control Group

    • Operationalisation involves defining abstract concepts in concrete terms.
    • A control group is used as a comparison group to ensure that the results are not due to extraneous variables.

    Confounding Variables and Experiments

    • A confounding variable is a variable that may be influencing the dependent variable in a systematic way.
    • Experiments provide the cleanest findings of any research method in psychology.

    Case Studies and Survey Research

    • Case studies are in-depth examinations of a single case or a small number of cases.
    • Random sampling helps to ensure that survey results accurately reflect the population as a whole without introducing systematic bias.

    Correlation and Causation

    • A correlation coefficient measures the extent to which two variables are related.
    • A negative correlation indicates that as one variable increases, the other decreases.

    Neuroimaging Techniques and Ethics

    • Modern neuroimaging techniques use computer programs to transform data from brain scans into images.
    • Ethics in research with animals involves balancing the costs to the animal against the benefits to humanity.

    Critical Thinking

    • Critical thinking involves scepticism, objectivity, and open-mindedness.
    • Critical thinking is essential in evaluating research findings and avoiding misleading conclusions.

    Variables and Hypothesis

    • A variable is a characteristic that can differ from one situation to another or from one person to another.
    • A hypothesis is a tentative belief about the relationship between two variables.### Reliability and Validity
    • A reliable measure provides consistent results each time it is used for its intended purpose.
    • There are four types of reliability: test-retest, internal consistency, interrater reliability, and they are all important and necessary in different contexts.
    • A reliable measure does not fluctuate substantially despite the presence of random factors that might influence the results.

    Types of Validity

    • External validity refers to the ability to generalize findings to situations outside the laboratory.
    • Generalisability refers to the applicability of the findings to the entire population of interest to the researcher.
    • A valid measure can predict other variables with which it should, theoretically, be related.

    Research Methods

    • An experiment involves manipulating variables and measuring their effects on behaviour.
    • The goal of an experiment is to establish cause-and-effect relationships between variables.
    • Inferential statistics help draw conclusions about a population from what happens to a sample.

    Experimental Design

    • Experimental designs have several advantages, including replication and the establishment of cause-and-effect relationships.
    • One of the key strengths of experimental research is the increased confidence in causality.
    • Weaknesses of experimental research include limited generalizability outside the laboratory and difficulties in controlling complex phenomena.

    Quasi-Experimental Design

    • A quasi-experimental design is similar to an experimental design, but lacks random assignment to conditions.
    • The major weakness of a quasi-experimental design is the lack of random assignment.

    Case Study

    • Case studies are not highly generalizable and are not an appropriate source of hypotheses.
    • Case study methods can be used in combination with quantitative or experimental procedures and are useful at the beginning or end of a series of studies.

    Scientific Approach to Research

    • The scientific approach has three main goals: description, prediction, and understanding.
    • Description involves summarizing data to make it easily understood.
    • Prediction involves using research outcomes to identify what would happen in the future.
    • Understanding involves identifying causal factors that led to research results.

    Hypothesis and Theory

    • A theory is a systematic way of organizing and explaining observations.
    • A hypothesis is a tentative belief about the relationship between two or more variables.

    Measurement in Research

    • Measurement is the process of turning an abstract concept into a numerical value.
    • Measurement can be complex and may require multiple measures to obtain information.

    Population and Sample

    • A population is a larger group of people that researchers intend to study.
    • A sample is a subgroup of the population that is representative of the population as a whole.

    Generalisability and Internal Validity

    • Generalisability refers to the ability to infer something about a larger population from the behavior of a subset of people.
    • Internal validity refers to the strength of the study design in ensuring that the procedures used to test the hypothesis are sound.

    Experimental Research

    • An experiment involves manipulating variables to observe their effects.
    • The different levels or variations of the independent variable are referred to as conditions.
    • The dependent variable is the response measured to see whether the experimental manipulation had an effect.

    Operationalisation and Control Group

    • Operationalisation involves defining abstract concepts in concrete terms.
    • A control group is used as a comparison group to ensure that the results are not due to extraneous variables.

    Confounding Variables and Experiments

    • A confounding variable is a variable that may be influencing the dependent variable in a systematic way.
    • Experiments provide the cleanest findings of any research method in psychology.

    Case Studies and Survey Research

    • Case studies are in-depth examinations of a single case or a small number of cases.
    • Random sampling helps to ensure that survey results accurately reflect the population as a whole without introducing systematic bias.

    Correlation and Causation

    • A correlation coefficient measures the extent to which two variables are related.
    • A negative correlation indicates that as one variable increases, the other decreases.

    Neuroimaging Techniques and Ethics

    • Modern neuroimaging techniques use computer programs to transform data from brain scans into images.
    • Ethics in research with animals involves balancing the costs to the animal against the benefits to humanity.

    Critical Thinking

    • Critical thinking involves scepticism, objectivity, and open-mindedness.
    • Critical thinking is essential in evaluating research findings and avoiding misleading conclusions.

    Variables and Hypothesis

    • A variable is a characteristic that can differ from one situation to another or from one person to another.
    • A hypothesis is a tentative belief about the relationship between two variables.### Reliability and Validity
    • A reliable measure provides consistent results each time it is used for its intended purpose.
    • There are four types of reliability: test-retest, internal consistency, interrater reliability, and they are all important and necessary in different contexts.
    • A reliable measure does not fluctuate substantially despite the presence of random factors that might influence the results.

    Types of Validity

    • External validity refers to the ability to generalize findings to situations outside the laboratory.
    • Generalisability refers to the applicability of the findings to the entire population of interest to the researcher.
    • A valid measure can predict other variables with which it should, theoretically, be related.

    Research Methods

    • The goal of an experiment is to establish cause-and-effect relationships between variables.
    • Inferential statistics help draw conclusions about a population from what happens to a sample.

    Experimental Design

    • Experimental designs have several advantages, including replication and the establishment of cause-and-effect relationships.
    • One of the key strengths of experimental research is the increased confidence in causality.
    • Weaknesses of experimental research include limited generalizability outside the laboratory and difficulties in controlling complex phenomena.

    Quasi-Experimental Design

    • A quasi-experimental design is similar to an experimental design, but lacks random assignment to conditions.

    • Case study methods can be used in combination with quantitative or experimental procedures and are useful at the beginning or end of a series of studies.

    Experimental Research

    • Experimental research has several advantages, including the ability to establish cause-and-effect relationships, replication, and application to real-world situations.
    • In an experiment, a researcher manipulates one or more independent variables and measures their effect on one or more dependent variables.

    Quasi-Experimental Design

    • In a quasi-experimental design, participants are not randomly assigned to conditions, unlike in experimental design.
    • This design is useful when random assignment is not possible, such as when studying the effect of gender or age on a particular outcome.

    Case Studies

    • Case studies involve in-depth analysis of a single case or a small number of cases.
    • They are useful for generating hypotheses and exploring phenomena in detail.

    Naturalistic Observation

    • Naturalistic observation involves observing behavior in a natural setting, without interference or manipulation.
    • It is useful for discovering patterns and relationships in real-world situations.

    Correlational Research

    • Correlational research examines the relationship between two or more variables.
    • It is useful for identifying patterns and relationships between variables, but cannot establish cause-and-effect relationships.

    Ethics in Research

    • Informed consent is essential in research, ensuring that participants understand the study and can withdraw at any time.
    • Deception may be used in research, but only with proper debriefing and justification.
    • Animals have rights and cannot give informed consent, so their use in research is subject to ethical guidelines.

    Theory and Hypotheses

    • A theory is a systematic way of explaining observations and making predictions.
    • A hypothesis is a specific prediction made based on a theory.
    • Variables can be categorical, continuous, or nominal, and must be operationalized in a study.

    Reliability and Validity

    • Reliability refers to the consistency of a measure, whether it produces similar results over time or across different observers.
    • Validity refers to whether a measure assesses what it claims to measure.
    • Internal validity refers to the soundness of a study's design, while external validity refers to the generalizability of the findings.

    Measurement and Data

    • Measurement involves assigning numbers to variables to make them quantifiable.
    • Data can be nominal, ordinal, interval, or ratio, depending on the level of measurement.

    Experimental and Quasi-Experimental Design

    • Experimental design involves manipulating an independent variable and measuring its effect on a dependent variable.
    • Quasi-experimental design is similar, but lacks random assignment to conditions.

    Critical Thinking and Science

    • Scepticism is essential in science, involving critical evaluation of assumptions and evidence.
    • Empiricism involves testing hypotheses through observation and experimentation.
    • The context of justification involves testing hypotheses and theories, while the context of discovery involves generating hypotheses and theories.### Independent and Dependent Variables
    • In an experiment, the independent variable is the factor that is manipulated or changed by the experimenter between groups of subjects.
    • The independent variable is independent of the control of the participants in an experiment.
    • In a study, the independent variable (IV) is the factor that is manipulated or changed by the experimenter, while the dependent variable (DV) is the response made to the independent variable.

    Experimental and Control Groups

    • Participants who are in the group that experiences a neutral condition in relation to the independent variable (i.e., who have not been exposed to the experimental condition) are said to be in the control group.
    • Any condition that involves exposure to some level of the independent variable is an experimental condition.
    • In an experiment, participants who receive the experimental condition are in the experimental group, while those who do not receive the experimental condition are in the control group.

    Research Design

    • A double-blind study is one in which both the participants and the researchers who interact with them do not know who has been exposed to which experimental condition until the research is completed.
    • Random assignment of participants to the experimental and control groups is essential for internal validity because participants in each group are unlikely to differ in some systematic way.
    • Demand characteristics are the ways in which participants' perceptions of the researcher's goals affect their responses in an experiment.

    Operationalizing Variables

    • Operationalizing a variable involves turning an abstract concept into a concrete variable by clearly defining its meaning.
    • In a study, an independent variable can be operationalized by manipulating the level of the variable to see its effect on a dependent variable.

    Confounding Variables

    • A confounding variable is one that can influence the results but was not intended to be included in the study.
    • Confounding variables can compromise the internal validity of the study by confounding the effects of the independent variable.

    Statistical Analysis

    • Descriptive statistics are used to summarize the essential features of a data set.
    • Inferential statistics are used to determine whether the relationship between the independent and dependent variable is meaningful and unlikely to have been caused by chance.

    Experimental Design

    • A study is best described as experimental if it involves random assignment of participants to groups and manipulation of the independent variable.
    • Quasi-experimental designs do not involve random assignment of participants to groups.
    • Correlational designs involve measuring the relationship between two or more variables without manipulating the independent variable.

    Research Methods

    • In an experiment, the investigator focuses on manipulated variables and their effects on behaviour, is interested in cause-effect relationships, and manipulates some factor.
    • Psychology takes an empirical approach to research that involves the rigorous testing of theories using methods that can be replicated.

    Notable Studies

    • The Harlow study found that infant monkeys were drawn to their mothers by the security and comfort provided, not by the mother's role as a source of food.
    • The study showed that attachment is not just about nourishment, but also about security and comfort.

    Placebo Effect and Statistics

    • A placebo effect occurs when simply believing that a treatment is effective has an impact.
    • Inferential statistics help draw conclusions about a population from what happens to a sample.

    Research Methods

    Research Design

    • A positive correlation between two variables means that the higher individuals measure on one variable, the higher they are likely to measure on the other.
    • Correlation does not necessarily imply causation; an underlying aspect of personality may explain the outcome.

    Ethics in Research
