Q

Deductive Reasoning

A

Reasoning proceeding from broad basic principles applied to specific situations
E.g., Betting that a particular team will win a playoff game because it is the home team and you beliebe the home team had an advantage

Q

Hypothetico-deductive Reasoning

A

Process of modern science where scientists begin with an aducated guess, perhaps based on prvious research about how the world works, then set about designing small controlled observations to support or invalidate that hypothesis

Research Ethics Board (REB)
Research oversight group that evaluates research to protect the rights of participants in the study
26
Informed Consent
What occurs when researchers give as uch information as possible about the purpose, procedures, risks, and benefits of the study so that a participant can make an informed decision about whether or not to participate
27
Debriefing
The supplying of full information to participants at the end of their participation in a research study
28
T-test
Psychologists compare mean by using T-tests, which are for groups of 2
29
Analyses of Variance
Psychologists compare mean by using analyses of variance, which is for 2 or more groups
30
Demand Characteristics
Set up studies so that they do not unintentionally convey to participants the outcome that they expect to see
31
Sampling Bias
Selecting a group that is ecpecially likely to confirm your hypothesis
32
Operationalize
To develop a working defention of a variable that allows you to test it
33
Single-blind Procedure
Only the researcher doing the study knows which treatment the participant is reciving until trial is over
34
Neuroscience
The study of the brain and nervous system
35
Electroencephalography (EEG)
A non-invasive technique used to detect and localize electrical activity in the brain
36
Neuroimaging
Techniques that allow for studying brain activity and structure by obtaining visual images in awake humans
37
Neuroimaging techniques include...
MRI & fMRI, CT, PET, TMS, DTI
38
Neuron
A nerve cell that carries info between parts of the body and nervous system
39
Afferent Neurons
Neurons that carry sensroty info from PNS to CNS
40
Efferent Neurons
Neurons that carry info out from CNS to PNS
41
Interneurons
Neurons that typically have a short axon and serve as a relay between different classes of neurons
42
Somatic Nervous System
Gather sensory information from the body, neck. and head and deliver it to the spinal cord and brain. Peripheral nerves that transmit information about body sensation and movement to and from the CNS - Controls voluntary muscles and conveys sensory information
43
Autonomic Nervous System
Comprises the sympathetic and parasympathetic nervous systems - Controls involuntary basic life functions, such as heart beat, and response to stress
44
Sympathetic Nervous System
Part of the autonomic nervous system that is activated under conditions of stress - Responsible for fight-or-flight
45

Axon
The part of the neuron that carries information away from the cell body toward other neurons
71
Axon Terminal
The end of a neurons axon, from which neurotransmitters are released
72
Glia
The cells that, in addition to neurons, make up the nervous system
73
Astrocytes
Creates blood-brain barrier, influences communication between Neurons, and helps heal brain damage
74
Oligodendroglia
Provides myelin to speed up transmission of neurons
75
Microglia
Cleans up dead cells and prvents infection in the brain
76
Resting Potential
The electrical charge of a neuron when it is at rest
77
Synapse
Tiny spaces between the axon terminal of one neuron and the neuron through which chemical communication occurs
78

79
Evolution
The process of development and divergence of life on this planet
80
