  • great environmental influences
    • twins (e.g. Identical) / genetics
        • what will happen to the twins behaviour if the twins are separated?**

Freud!
-caused by conscious and unconscious conflicts

Q

Research methods: experimentation

A

Manipulates one or more factors (independent variable) to observe the behaviour process or mental process of another (dependant)

  • experimental group - exposed to the treatment
  • control group - not exposed to the treatment
  • confounding variables; causing the change,
  • demanding characteristics; giving the results the experimenter wants
  • experimenter expectancy- influencing the subjects unconsciously.
  • placebo effect- changed based on expectations
  • blind study- subjects are in the dark about other groups
  • double blind- subjects & experimenter are in the dark about other groups.

Q

Behaviourism

A

The view the psychology (1) should be an objection science that (2) studies behaviour without reference to mental processes. Most research psychologists today agree with (1) but not with (2)

Q

Nature-nurture issue

A

The longstanding controversy over the relative contributions that genes and experience make to the development of psychological traits and behaviour s.

The scientific study of human functioning, with the goals of discovery and promoting strengths and virtues that help individuals and communities to thrive.
28
Psychology: a science and a profession
Psychologist experiment with, over serve, tests and treat behaviour. Here we see psychologist testing a child, measuring emotion-related physiology, and doing face-to-face therapy.
29
Hindsight bias
The tendency to believe, after an outcome, that one would have foreseen it, "I knew it all along"
30
Critical thinking
Thinking that does not blindly accept arguments and conclusions. "What do you mean" "how do you know"
31
Theory
An explanation using an integrated set of principles that organizes observations and predictions on behaviours or events
32
Hypothesis
A testable predictions, often implied by a theory
33
Operational definition
A statement off the procedures (operations) used to define research variables. For examples, human intelligence maybe operationally defined as "what an intelligence test measures."
34
Replication
Repeating the essence of a research study, usually with different participants in different situations, to see whether the basic finding extends to other participants and circumstances
35
Case study
An observation technique in which one person is studied in depth in the hope of revealing universal principles
36
Naturalistic observation
Observing and recording behaviour in naturally occurring situations without trying to manipulate and control the situations
37
Survey
A technique for ascertaining the self reported attitudes or behaviours of a particular group, usually by questioning a representative, random sample of the group
38
Population
All those in a group being studied, form which studies can be drawn
39
Random sample
A sample that fairly represents a population because each member has an equal chance of inclusion
40
Experimentation
A research method in which an investigator manipulates one or more factors (independent) to observe the behavioural process of another (dependant)
41
Experimental group
In an experiment, the group is exposed to the treatment, that is, to one version of the independent
42
Control group
Not expensed to the treatment. Used as base to contrast with those that received the treatment
43
Random assignment
Assigning control group and experimental groups by chance, therefor minimizing differences between the different groups
44

49
Blind study
Subjects are in the dark about the other groups
50

51
Confounding variable
A factor other than the independent variable that might produce an effect in an experiment
52
Dependant variable
The outcome factor; the variable that may change in response to manipulations of the independent variable
53

The enduring behaviours, ideas, attitudes, values, and traditions by a group and transmitted from one generation to the next
