Biopsychoogy

Question 1

L o F-
Two strengths?

Answer 1

EVIDENCE FROM NEUROSURGERY. Tests mental disorders as last resort. Cingulotomy- OCD, 30% reduction.

EVIDENCE FROM BRAIN SCANS. Wernickes area active during listening. LTM stores in different brain parts

Question 2

L o F-
One limitation?

Answer 2

LANGUAGE LOCALISATION QUESTIONED. Only 2% think language is only controlled by Broca’s and wernickes

Question 3

HL + SB-
Two strengths?

Answer 3

LATERALISATION IN THE CONNECTED BRAIN. PET scans during visual processing task, looking at while image= active RH, small details= acute LH.

RESEARCH SUPPORT. Sb perform better on some tasks than control. Faster at identifying similar objects.

Question 4

HL + SB-
Two limitations?

Answer 4

ONE BRAIN. Do not have a dominant side of the brain which creates different personalities.

GENERALISATION ISSUES. Compared to neurotypical group, confounding variables.

Question 5

P +FR-
Two strengths?

Answer 5

AGE AND PLASTICITY. Typically reduces with age, golf study, high grey matter in motor cortex.

REAL WORLD APPLICATION. Contributed to neurorehabilitation, constraint-induced movement therapy (repeated practice).

Question 6

P +FR-
Two limitations?

Answer 6

NEGATIVE PLASTICITY. Prolonged drug use leads to poorer cognitive functioning in later life. 60/70% amputees develop phantom limb syndrome.

COGNITIVE RESERVE. More time in education = less likely to gain a disability.

Question 7

Ways of studying the brain-
Four strengths?

Answer 7

(fMRI), DOES NOT USE RADIATION.
(EEG), STUDIES STAGES OF SLEEP.
(ERP), MUCH MORE SPECIFIC.
(PME), FOUNDATION FOR EARLY UNDERSTANDING.

Question 8

Ways of studying the brain-
Four limitations?

Answer 8

(fMRI), EXPENSIVE
(EEG), GENERALISED NATURE OF INFO
(ERP), LACK OF STANDARDISATION
(PME), OBSERVED DAMAGE MAY NOT BE LINKED TO WHAT IS BEING LOOKED AT.

Question 9

BR: CR-
Two strengths?

Answer 9

SHIFT WORK. Night workers=reduced concentration @6am, correlation between poor health and night shifts.

MEDICAL TREATMENT. Co-ordinal e basic processes, aspirin is best for heart attacks at night.

Question 10

BR: CR-
One limitation?

Answer 10

INDIVIDUAL DIFFERENCES. Very small pps sample.vary from 13 to 65 hours. Larks (early early), owls (late late).

Question 11

BR: I + U R-
Two strengths?

Answer 11

EVOLUTIONARY BASIS. Synchs up in case mother dies in childbirth.

IMPROVED UNDERSTANDING. Believe SWS reduces with age, growth hormone.

Question 12

BR: I + U R-
Two limitations?

Answer 12

METHODOLOGICAL LIMITATIONS. Confounding variables, many factors affect menstrual cycle.

INDIVIDUAL DIFFERENCES. Change sin duration of each sleep stage.

Question 13

EP + EZ-
One strength?

Answer 13

BEYOND THE MASTER CLOCK. Numerous CR in different organs, lung, pancreas, skin. Influenced bug independent.

Question 14

EP + EZ-
Three limitations?

Answer 14

INTERACTIONIST SYSTEM. Siffes total isolation is rare. Used artificial light, could have reset biological clock.

ENVIRONMENTAL OBSERVATIONS. Similar sleep patterns all year, artic circle (little light in winter, little dark in summer).

CASE STUDY EVIDENCE. Blind from birth, abnormal s/w cycle, despite social cues,
