  1. a general effect of deprivation on organism's reaction to a range of stimuli
  2. b a relation in which the occurrence of one event depends on the occurrence of another event
  3. c the occurrence of two events with a very short time interval between them
  4. d a pair of fine wires, insulated from one another except at their tips, that is inserted into a brain region to stimulate neurons or monitor their activity
  5. e reduction of contact with a stimulus to levels below ad libitum (normal free access) levels (2)

5 Multiple choice questions

  1. stimulus that functions to establish other stimuli as reinforcers or punishers.
  2. a region of the brain whose stimulation functions as a particular effective reinforcer.
  3. stimulus that functions as reinforcer in operant procedures by having been paired with other reinforcers.
  4. the effectiveness with which a signal from a presynaptic neuron activates a postsynaptic neuron
  5. an object or event that includes separable stimulus components, such as a light and a tone

5 True/False questions

  1. blockinga neuromodulator released by neurons in the VTA; its presence in a synapse produces long term increases in synaptic efficacy (2)


  2. instrumental (operant) conditioninglimitations, resulting from natural selection, on the outcome of behavioral selection by reinforcement


  3. unified principle of reinforcement1; rule of learning incorporating selection processes in classical & operant procedures; 2; states that when a behavioral discrepancy occurs, an environment-behavior relation is selected consisting of stimuli present immediately before the discrepancy and responses occurring just before the elicited response


  4. input unitsan element of an adaptive neural network, simulating the activity of a neuron or group of neurons that mediate behavioral events


  5. superstitious behaviorincrease in response probability to a range of other stimuli resulting from (usually intense) stimulus presentation
