Psychology as a scientific disipline correct answers Psychology is a scientific
investigation of mental processes, behaviour, and the interaction between them
What are the philosophical foundations of psychology correct answers - free will vs.
determinism
- nature (biology) vs. nurture (environment)
- reason vs. emotion
- mental vs. physical (mind/body)
Who founded structuralism? correct answers Wilhelm Wundt
Who founded functionalism? correct answers William James
What is structuralism? correct answers A psychological method that used introspection
to uncover basic elements of consciousness.
What is functionalism? correct answers Functionalism proposes that consciousness is
functional and serves a purpose
The 5 main psychological perspectives are... correct answers - psychodynamic
- behaviourist
- humanistic
- cognitive
- biological/evolutionary
What is the psychodynamic perspective? correct answers A theory that believes that
conscious and unconscious forces interact to control thoughts and behaviours. It
believes that behaviour is an interplay between thoughts, feelings and wishes. Some
mental events are unconscious. Mental processes can be in conflict which can result in
anxiety.
What is the behaviourist perspective? correct answers A theory that believes that
environmental stimuli control behaviour through learning
The behaviour of humans (and animals) can be learned without reference to internal
states such as thoughts or feelings
, What is the humanistic perspective? correct answers A theory that focuses on the
uniqueness of the individual and that people are motivated to reach their full potential
(self-actualisation). The humanistic perspective is person-centred
What is the evolutionary perspective? correct answers A theory that believes human
behaviours are evolved because they helped our ancestors survive and reproduce.
Some behaviours are biologically determined (e.g. the impulse to eat, sexual impulses)
The key parts of a neuron and their functions are... correct answers - dendrites (where
information is received)
- cell body (where information is processed)
- nucleus (holds cell DNA)
- axon (carries signals away from cell body)
- myelin sheath (provides insulation)
- nodes of ranvier
- terminal buttons/axon terminals (hold neurotransmitters)
What is a synapse? correct answers The point where cells meet. When cells meet, they
do not touch, instead there is a very small space. This space is called a synaptic cleft
What is a presynaptic cell? correct answers neuron that sends message
What is a postsynpatic cell? correct answers neuron that receives message
How do cells communicate? correct answers 1. cell sends an electrical charge through
the axon towards the presynaptic terminal
2. the electrical charge stimulates the presynaptic terminal to release chemical charges
(neurotransmitters)
3. Chemical messages (neurotransmitters) cross the synaptic cleft and are taken up by
the post synaptic terminal
4. The post synaptic terminal is then stimulated, producing an electric charge... and so
on
What are action potentials? correct answers The signal that the cell produces
What is an excitatory postsynaptic potential (EPSP)? correct answers If an action
potential is excitatory, it makes the cells electrical potential closer to 0 (from -70)
Makes the cell excited
EPSP's depolarise the neuron
This means the cell is more likely to produce an action potential
What is an inhibitory postsynaptic potential (IPSP)? correct answers If an action
potential is inhibitory, it makes the cells electrical potential
Hyper-polarise the cell
Makes the cell less likely to produce an action potential
