BLO: Part One: Short Answer Flashcards

1
Q

Principles of BLOA

A
  1. Behavior can be innate because it is genetically based. Evolution may be a factor.
  2. Animal research can provide insight into human behavior.
  3. Thinking, emotions and behaviors are products of anatomy and physiology or our nervous and endocrine systems.

16
Q

nervous system

A

the network of nerve cells and fibers that transmits nerve impulses between parts of the body

17
Q

endocrine system

A

collection of glands that produce hormones that regulate metabolism, sleep, mood, growth and development

18
Q

ecological validity

A

The extent to which the same result would be found in the real world

19
Q

BLOA strengths and weaknesses

A

Strengths: technology and scientific studies
Weaknesses: ecological validity from tests, animal testing, small samples

20
Q

Neurotransmission

A

The process in which a chemical message travels down the body of a neuron and the axon to the synapse, the gap between two neurons, the neurotransmitters cross that gap.

21
Q

Informed consent

A

participants must be informed about the nature of the study and agree to participate

22
Q

Deception

A

Slight deception is allowed to not alter the results but must be explained later

23
Q

Debriefing

A

True aims and purposes must be revealed at the end of the study

24
Q

Withdrawal

A

Participants can leave the study at any time and withdraw their results

25
Q

Protection from physical and mental harm

A

May not humiliate a participant or force them to reveal private information

26
Q

Confidentiality

A

All info must be confidential

27
Q

Expirements

A

Uses a tightly controlled environment to establish a cause and effect relationship

28
Q

Case studies

A

When scientists want to follow the case of a human with a particular type of damage or when the topic is a new field of study

29
Q

Postmortem studies

A

Conducting an autopsy after the subject has died

30
Q

Neuroimaging technologies

A

Using new technology like the CAT, MRI, fMRI to collect quantitative data

31
Q

Correlational studies

A

Establishes a relationship between two variables without manipulating a variable

32
Q

Triangulation

A

Using multiple methods of investigation to explore the same phenomenon
