Question 1

What’s an Isovolumetric/isochoric process? How does it relate to work?

Answer 1

Isovolumetric means that volume is constant, does not change. If volume is constant, work = pressure x change in volume. Work = pressure * 0 = 0!

Question 2

For a gas, how do we correlate expansion/compression of gas to work?

Answer 2

Work = Force x distance = P x V When a gas is compressed by an external pressure, work is being done ON THE GAS. Work = Negative, because volume decreases. When a gas expands, it’s pushing against the piston, so work is done BY GAS. Work = Positive, because volume increases.

Question 3

Describe Bandura’s Social Cognitive Theory

Answer 3

Describes how we learn something. Mnemonic: AM I Motivated? Attention Memory Imitation Motivation (Above things are needed to learn something)

Question 4

Synaptic plasticity

Answer 4

The ability of synapses to strengthen their connections, which is important in learning. After lots of pre-synaptic practice, the same level of stimulation can cause greater changes in post synaptic neuron - known as long term potentiation. Same signal over time, leads to bigger changes in post synaptic neuron

Question 5

What is non-associative learning?

Answer 5

Behavior in a situation that isn’t reinforced/punished, in contrast to operant conditioning/associative learning. Ex: Habituation - decreased response to stimulus over time Sensitization - increased response to stimulus over time

Question 6

Power

Answer 6

Rate at which work is done. Power = Work/time = Change in Energy/time Units = Joules / second = Watt

Question 7

Dishabituation

Answer 7

After habituation, the recovery of conditioned response to condition stimulus, usually when a second stimulus is presented

Question 8

How do we know when classical conditioning has taken place?

Answer 8

When neutral stimulus becomes conditioned stimulus - acquisition of conditioned response. Neutral stimulus elicits the same reaction as an unconditioned stimulus.

Question 9

Discrimination in stimulus response

Answer 9

When human learns to respond to a certain stimulus over others. Ex: we’d respond differently to gunshot compared to drum, even though both are quick noises.

Question 10

What are psychoactive drugs? What are the 4 kinds?

Answer 10

Drugs that alter consciousness / moods -depressants -hallucinogens -stimulants -opiates
