2 of 66

3 of 66
Adrenaline

axon

6 of 66
Axon terminal

The theory that human and animal behaviour can be explained in terms of conditioning, without considering thoughts or feelings
8 of 66
Central nervous system
Sub-system of the nervous system that consists of the brain and spinal cord
9 of 66

10 of 66

12 of 66
Computer models

13 of 66
Concordance rate
The extent to which both twins share the same characteristic
14 of 66
Dendrites
Root like structures protruding from the cell body that receive signals from other neurons
15 of 66
DZ twins
Non-identical twins who share 50% of their genes
16 of 66
Empirical
Based on scientific testing or personal experience rather than theory or logic
17 of 66
Endocrine system
A collection of organs that secrete hormones into the blood stream
18 of 66
Evolution
Gradual changes in an inherited characteristic of a species over many generations
19 of 66
Excitation
Occurs when a link between a neurotransmitter and receptor site in a synapse makes the receptor site’s cell more likely to act
20 of 66
Fight or flight response
The way an animal (including humans) responds to stress as it becomes physiologically aroused to fight an aggressor or to run away
21 of 66
Genotype
A person's unique genetic make-up that is coded in their chromosomes and fixed at conception
22 of 66
Hormones
Biochemical substances that circulate in the bloodstream in order to target specific organs
23 of 66
Hypothalamus
Part of the brain that links the nervous system to the endocrine system. Releases hormones that stimulate the pituitary gland
24 of 66
Identification
Associating with a role model's and adopting their behaviour because you want to be like them
25 of 66
Inference
Process of drawing conclusions about general patterns of behaviour
26 of 66
Information processing model
The idea that information flows through the cognitive system in a sequence of stages
27 of 66
Inhibition
occurs when a link between a neurotransmitter and receptor site in a synapse makes the receptor site’s cell less likely to act.
28 of 66
Internal mental processes
The operations both conscious and unconscious that occur during thinking. For example, perception and memory
29 of 66
Introspection
Observing and examining your own conscious thoughts and emotions
30 of 66
Learning
A relatively lasting change in behavior that is the result of experience
31 of 66
Mediating cognitive factors
Internal mental processes that lie between the stimulus and the response
32 of 66
Modelling
Imitating a role model or producing a specific behaviour that may then be imitated by the observer
33 of 66
Motor neuron
Carries signals from the central nervous system to internal organs and muscles
34 of 66
Myelin sheath
A fatty layer that protects the exon and speeds up the electrical transmission of the nerve impulse
35 of 66
MZ twins
Identical twins who share 100% of their genes
36 of 66
Natural selection
The way that any genetically determined behaviour that enhances the ability to survive and reproduce will continue in future generations
37 of 66
Negative reinforcement
Avoiding or removing something unpleasant when a behaviour is performed that increases the chance tha the behaviour is repeated
38 of 66
Nervous system
Bodily system consisting of central nervous system and peripheral nervous system that provides rapid responses to stimuli
39 of 66
Neuron
Cells within the nervous system that process and transmit messages
40 of 66
Neurotransmitter
Chemicals that transfer signals from one neuron to another across the synapses that lie between them
41 of 66
Objective
Not influenced by private emotions, perceptions, or biases
42 of 66
Operant conditioning
Learning through reinforcement where behaviour is shaped and maintained by its consequences
43 of 66
Parasympathetic nervous system
Sub-division of the autonomic nervous system that controls the 'rest and digest' response
44 of 66
Peripheral nervous system
Sub-system of the nervous system that transmits messages from the body to the central nervous system and back again
45 of 66
Phenotype
The expression of a person's genetic make-up that can be influenced by the environment
46 of 66
Pituitary gland
The 'master gland' of the endocrine system which is located in the brain and controls the release of hormones from other glands
47 of 66
Positive reinforcement
Receiving something pleasant when a behaviour is performed that increases the chance the behaviour is repeated
48 of 66
Postsynaptic Receptor sites
In the dendrites of the receiving neuron, they take up the neurotransmitter once it has crossed the synaptic gap
49 of 66
Punishment
Receiving something unpleasant when a behaviour is performed which decreases the chance the behaviour is repeated
50 of 66
Reciprocal determinism
The way a person is influenced by their environment but also influences their environment
51 of 66

Carries signals between sensory and motor neurons or connect to other relay neurons within the central nervous system

Response
The reaction to a specific stimulus e.g. salivating when you see food
