Q

Why might it be beneficial that the behaviour of nonhuman subjects is often simpler than human subjects?

A

The simpler the behaviour, the more likely it is to reveal fundamental brain-behaviour interactions

Q

What are “the three R’s” emphasized by nonhuman animal ethics committees, and what do they mean?

A
  • Reduction (reduce the number of animals used)
  • Refinement (refine research studies and/or the treatment of animals to reduce suffering)
  • Replacement (replace animal subjects with alternate techniques)

25
What is a dependent variable?
The variable measured by the researcher to assess the effect of the independent variable
26
What is a confounded variable?
An unintended difference between experimental conditions that may have affected the dependent variable
27
What are quasi experimental studies?
Studies of groups of subjects who have been exposed to the conditions of interest in the real world (the independent variable is naturally occurring)
28
When are quasi experimental studies used?
When controlled experiments are not possible
29
What are quasi experimental studies able to demonstrate?
Correlation
30
What are case studies?
Studies that focus on a single subject, or very small number of subjects
31
What is the major problem with all case studies?
Their lack of generalizability
32
What is pure research?
Research motivated primarily by the researcher's desire to acquire knowledge
33
What is applied research?
Research that is intended to bring about some direct benefit to humankind
34
What is translational research?
Research that aims to translate the findings of pure research into useful applications for humankind
35
What is the Coolidge effect?
The fact that a copulating male who becomes incapable of continuing to copulate with one sex partner can often recommence copulating with a new sex partner
36
What are the six major divisions of biopsychology?
- Physiological psychology - Psychopharmacology - Neuropsychology - Psychophysiology - Cognitive neuroscience - Comparative psychology
37
What is the youngest division of biopsychology?
Cognitive neuroscience
38
What is physiological psychology?
The division of biopsychology that studies the neural mechanisms of behaviour through direct manipulation of the brains of nonhuman animal subjects in controlled experiments
39
Does physiological psychology have a tradition of pure or applied research?
Pure
40
What is psychopharmacology?
The division of biopsychology that studies the effects of drugs on the brain and behaviour
41
Does psychopharmacological research tend to be pure or applied?
Applied (ex. developing therapeutic drugs)
42
What is neuropsychology?
The division of biopsychology that studies the psychological effects of brain damage in human patients
43
What kinds of research methods are used in neuropsychology?
Case studies and quasi experimental studies of patients with brain dysfunction
44
What is psychophysiology?
The division of biopsychology that studies the relation between physiological activity and psychological processes in human subjects by noninvasive methods
45
What is an electroencephalogram?
A measure of the gross electrical activity of the brain, commonly recorded through scalp electrodes
46
What is cognitive neuroscience?
The division of biopsychology that focuses on the use of functional brain imaging to study the neural mechanisms of human cognition
47
What is functional brain imaging?
Recording images of the activity of living human brains
48
What is comparative psychology?
The division of biopsychology that studies the evolution, genetics, and adaptiveness of behaviour
49
What is ethnological research?
The study of an animal's behaviour in its natural habitat
50
What are converging operations?
The use of several research approaches to solve a single problem
51
What is Korsacoff's syndrome largely caused by?
Brain damage associated with a thymine (vitamin B1) deficiency
52
What is scientific inference?
The logical process by which observable events are used to infer the properties of unobservable events
53
What is Morgan's canon?
The rule that the simplest possible interpretation of a behavioural observation should be given precedence
54
In Case 1 of Chapter 1, what did Jose Delgado claim to have discovered?
The caudate taming centre and that its stimulation could eliminate aggressive behaviour
55
What is a prefrontal lobotomy?
A surgical procedure in which the connections between the prefrontal lobes and the rest of the brain are cut
56
What is a leucotome?
A surgical device used in psychosurgery to cut out a core of brain tissue
57
What were Dr. Egas Moniz's claims about lobotomies based on?
A report that two chimpanzees who frequently became upset when they made errors did not do so following the creation of a large bilateral lesion of their prefrontal lobes
58
What is a bilateral lesion?
Damage to both sides of the brain
59
What is psychosurgery?
Any brain surgery performed for the treatment of a psychological problem
60
What is a transorbital lobotomy?
A prefrontal lobotomy performed with an instrument inserted through the eye socket
