Science and Professional Practice in Psychology
Question | Answer |
---|---|
Scientific Theory is - | - Based on evidence. - Reasonable explanations to describe reality - Explain and Predict - No theory is infallible, able to be modified - Describe measures in hypothesis - Must be testable - constructed to explain & predict phenomenon - Specific |
Hypothesis is - | A prediction derived from theory Makes a specific prediction |
Heuristics - 1 | - In Psychology, they are simple & efficient rules that have become hard‐coded by evolution - Useful when a quick decision is required or limited information is available, but usually lead to systematic errors & cognitive biases |
Heuristics - 2 | - Refers to experience based techniques for discovery, problem solving and learning - Heuristics are strategies that use readily accessible information |
Types of heuristics - Theres 8 | 1. Conjunction fallacy 2. Confirmation bias 3. Illusory correlation 4. Self‐fulfilling prophecy 5. Fundamental attribution error 6. Self‐serving bias 7. Availability/vividness effect 8. Representativeness |
Confirmation Bias - | The tendency to seek out information that confirms your beliefs. |
Conjunction fallacy - | The conjunction of two events can not be more likely than either one of the events alone. |
Representativeness heuristic | The tendency to presume, sometimes despite contrary odds, that someone or something belongs to a particular group if resembling (representing) a typical member. (Stereotypes, abstract) |
Availability Heuristic | A cognitive rule that judges the likelihood of things in terms of their availability in memory. If instances of something come readily to mind, we presume it to be commonplace |
Study Designs- Experimentation Designs (5) | Lab Vs. Field Experiment, Between Groups design, Within groups design, Matched pairs, Quasi-experimental design |
Study Designs- Correlational | Looking at relationships between two variables Positive or Negative relationships Does not establish causation |
Study Designs-Self-report measures | - Can be unreliable, people can lie -Easy to administer -Quick and cost little to perform |
Study Designs-Validity | - The extent to which measure correspond to world - Are you actually measuring what you think you're measuring? |
Study Designs-Reliability | - Consistency - Will you get same results when done again? - Test re-test - Reliability can be tested statistically (correlations) |
Study Designs-Random Assignment | - Randomly places people in experimental group - Everyone in population sample has equal chance of being represented - As sample size increases, difference between group decreases |
Study Designs- Independent variable | -Independent variable - the variable that's being manipulated |
Study Designs- Dependent variable | Dependent variable - the variable that's being measured (The effect) |
Study Designs- Control (Confounding) variable | Control - variables you have controlled for -Confounding variables - a variable that can impact the independent variable other than the dependant variable |
Study Designs- Placebo effect | - When a change is seen due to someone believing they are getting treatment/medication |
Informed Consent - General informed consent Guidelines | The APA & APS guidelines state that, to be able to provide informed consent, the individual must be competent to understand the research and the requirements of research |
Informed Consent - Children | - Consent must be obtained from parent and child - Maturity judgements considered - Children should only be used when there is no other option and participation will be of substantial benefit |
Informed Consent - Cognitively impaired Phased consent | - Providing opportunity to review materials and involvement, important working with vulnerable people and populations - Phased consent may be appropriate, providing potential to renegotiate consent as required throughout an emergent research process |
Ethics - Basic principles of Nuremberg code | 1. Autonomy 2. Non‐Maleficence and Beneficence 3. Justice |
Ethics - Justice | The benefits and burdens of research should be distributed as fairly as possible Everyone has an equal chance to participate/be represented |
Ethics - Autonomy | Respect for the rights and dignity of other people |
Ethics - Respect | Respect peoples right to withdraw. Respect capacity to understand consent |
Ethics - Scientific Integrity | Do not falsify data, findings presented honestly |
Falsifiability | Scientific theories must be stated in a way where they can be proved wrong (falsified) Example: All swans are white |
Heuristic - a thinking strategy that enables... | Quick, efficient judgements |
Belief perseverance | Persistence of one's initial conceptions, such as when the basis for one's belief is discredited but an explanation of why the belief might be true survives. |
Reliability with Validity - Low reliability, Low validity - High reliability, Low validity - | Low reliability, Low validity - Intelligence measured by broken bathroom scale, Useless Low validity, High reliability - Intelligence measured by bathroom scale, Useless |
Reliability with Validity - High validity, low reliability - High reliability, High validity - | High validity, Low reliability - Impossible High reliability, High validity - A useable operational definition! |
Falsifiability - | If P, then Q. Not Q. Therefore, not P If I am the axe murderer, then I used an axe. I cannot use an axe. Therefore, I am not the axe murderer |
The scientific method - Cycle | Theory - Prediction - Test |
Heuristics - Illusory Correlation | Seeing a relationship when one does not exist ‘Computer scientists nerdy, Holden drivers bogan’ |
Heuristics - Self‐fulfilling Prophecy | A prediction that causes itself to become true due to positive feedback between belief and behaviour |
Heuristics - Fundamental Attribution Error | The tendency to over‐value dispositional or personality based explanations for observed behaviours |
Heuristics - Self-serving bias | Tendency to attribute events incorrectly, often taking personal credit for positive outcomes and blaming negative outcomes on external events I did well on assignment as I am really smart I did poorly on assignment as the tutor is an idiot |
Ethics - Non‐Maleficence and Beneficence | Minimise the risk and maximise the benefits of the research |
Nuremberg Principles - Trust | Research should never undermine the trust the participants and the wider community place in us |
Nuremberg Principles - Fidelity and Scientific Integrity | Poorly conducted research is unethical Findings should be reported honestly and disseminated widely |
Autonomy - Core values | Informed consent Right to withdraw Vulnerable populations Power imbalances Coercion |
Trust - Core values | Confidentiality Deception Debriefing |
Beneficence - core values | Reciprocity Respect Equality Responsibility Survival and protection Spirit and integrity |
Informed consent 1 | -All research conducted in Psychology requires informed consent to be provided by participants - This applies to vulnerable populations also (more so) - Informed consent =process, not just a document the participant signs to take part in your study |
Issues when working with children - | - Capacity to understand what research entails, and therefore whether their consent to participate is sufficient for their participation -possible coercion to participate - Conflicting values and interests of parents and children |
Between groups design | Each participant gets exposure to one group. Each participant participants only once in the experiment |
Lab vs Field experiment | Field - Community psychology, social, observations Lab - Clinical psych/ looking at conditions |
Within-groups design | Participant completes all levels of experiment, eg. manipulation of variable and control group, at different times. |
Matched pairs design | Match data in pair form Match a person in each group based on similar data. E.g. Red wine causes worse hangover to white... compare two similar participants (one from each group) |
Quasi-experimental design | Pretend - usually in clinical studies -Lacks random assignment Assigned to groups based on symptoms -Usually in groups when group inclusion is needed Eg. Depression group & Non-depressed group. |
