Q

mental processes (=cognition, cognitive process)

A
  • way to explore what is happening in someone’s mind (e.g. internal thoughts, processes, memories to recall)

Q

qualitative research

A
  • exploratory
  • used to gain insight into psychological phenomena of interest
  • further research into the topic may also include quantitative studies with more data
  • case study, naturalistic observation, interviews

Q

case study

A
  • in-depth investigation of small group or individual
    • may be conducted over a long period of time (longitudinal) and/or
    • uses a range of different methods to gather data

  • descriptive starting point for exploring things more quantitatively

Q

deception

A

deception cannot be used without a valid justification. It is permissible if it is justified by the experiment & does not harm participants

Q

right to withdraw from participation

A

participants should be able to leave a study at any time if they feel uncomfortable. They should also be allowed to withdraw their data after the study

Q

confidentiality / anonymity

A

participants and the data gained from them must be kept anonymous unless they give full consent. No names must be used in a research report

Q

protection from undue stress or harm

A

researchers must endure that those taking part in the research will not be caused distress. They must be protected from physical and mental harm. You must not embarrass, frighten, offend or harm participants.

15
Q

correlational research

A
  • as one variable changes, so does the other
  • often unable to distinguish between IV and DV since we are just observing the relationship between variables
16
Q

quantitative research methods

A
  • experiments, field experiments, quasi-experiments, natural experiments, correlational research, surveys
17
Q

independent variable (IV)

A

factor in study that psychologists change to see the effect it might have on behaviour

18
Q

dependent variable (DV)

A
  • factor that researchers measure in the study
  • effect of the IV
19
Q

localization of function

A

theory that specific parts of the brain are responsible for specific behaviours or cognitive processes
- e.g. case study of H.M.

20
Q

different parts of brain

A
  • frontal lobe
  • occipital lobe
  • parietal lobe
  • temporal lobe
  • cerebellum
  • brain stem
21
Q

frontal lobe

A
  • personality
  • judgement
  • higher order thinking
22
Q

pariental lobe

A
  • interprets language & words
  • spatial & visual perception
23
Q

occipital lobe

A
  • interprets vision
24
Q

temporal lobe

A
  • understanding language
  • memory
  • emotion
25
Q

cerebellum

A
  • maintain posture & balance
  • motor movement memory
26
Q

brainstem

A
  • controls subconscious body functions: breathing, maintaining heart rate
  • sends signals from brain to rest of body
27
Q

case study - strengths

A
  • longitudinal
  • uses triangulation (data, method, researcher, theory)
  • holistic: looks at range of effects of the damage
  • establishes good starting points through qualitative research method
    • usually followed by quantitative research method
28
Q

case study - limitation

A
  • no cause & effect relationship can be determined since researchers don’t manipulate IV
  • cannot generalize findings to all human beings
  • cannot be replicated
  • retrospective: may be difficult to verify information about the patient before the accident took place
29
Q

quasi experiment

A
  • not all conditions of the experiment can be met
    • naturally occuring IV (e.g. gender, socioeconomic status)
30
Q

field experiment

A
  • researchers manipulate or assign IV
  • participants are sent off into their natural environment
  • e.g. Draganski (juggling MRI study)
31
Q

true experiment

A
  • research method that can determine that something “causes” something else
  • involves the researchers directly manipulating the IV themselves and randomly allocating participants into conditions in order to establish a causal claim
32
Q

Magnetic Resonance Imaging (MRI) - strength

A
  • non-invasive, minimal potential harm to patient (unlike PET)
  • faster result (unlike PET)
  • no special preparation needed (unlike PET)
  • provide localization & 3D structure of brain (unlike EEG)
33
Q

Magnetic Resonance Imaging (MRI) - limitation

A
  • only indicates structure
  • usually correlational, not allowing researchers to establish clear cause & effect relationship (unlike PET, fMRI and EEG)
  • cannot include participants who cannot be in the machine for 20-30 minutes (claustrophobic, metal implants, baby)
  • expensive (unlike EEG)
34
Q

Neuroplasticity

A
  • changes in neural pathways and synapses due to changes in behaviour, environment, thinking, emotions, as well as changes resulting from bodily injury
35
Q

difference between hormones and neurotransmitters

A
  • system: nervous system / endocrine system
  • speed: quick response, usually within milliseconds (happens at a synapse in the brain) / few minutes ~ few days to respond (has to travel around the body via the bloodstream)
  • after effects/lingering: doesn’t linger after / linger after
