Frage 1

Frage
Conditioned stimulus: [blank_start]bell, light[blank_end] Unconditioned stimulus: [blank_start]food, shock[blank_end] Conditioned response: [blank_start]has to be learned[blank_end] Unconditioned response: [blank_start]is innate[blank_end]
Antworten
  • bell, light
  • food, shock
  • has to be learned
  • is innate

Frage 2

Frage
The probability of occurence of a conditioned response decreases if the CS is repeatedly presented without the US. This is called [blank_start]extinction[blank_end].
Antworten
  • extinction

Frage 3

Frage
Which is true?
Antworten
  • Classical conditioning depends only on the temporal sequence of a CS followed by an US. The strength of the connection is determined by the number of pairings of CS and US.
  • Classical conditioning depends on more factors than just the sequence of CS and US. Animals can distinguish events that reliably occur together from those that are only randomly associated.

Frage 4

Frage
Predictive relationship between two stimuli: [blank_start]classical[blank_end] conditioning Predictive relationship between action and outcome: [blank_start]operant[blank_end] conditioning
Antworten
  • classical
  • operant

Frage 5

Frage
Timing is crucial in BOTH classical and operant conditioning.
Antworten
  • True
  • False

Frage 6

Frage
The term '[blank_start]blocking[blank_end]' describes the phenomenon that an association between two stimuli, a [blank_start]conditioned[blank_end] stimulus (CS2) and an [blank_start]unconditioned[blank_end] stimulus (US) is impaired if, during the conditioning process, the CS2 is presented together with a second CS1 that has already been associated with the unconditioned stimulus.
Antworten
  • blocking
  • conditioned
  • unconditioned

Frage 7

Frage
The law of [blank_start]effect[blank_end]: Responses that produce a satisfying effect in a particular situation become [blank_start]more[blank_end] likely to occur again in that situation, and responses that produce a discomforting effect become [blank_start]less[blank_end] likely to occur again in that situation.
Antworten
  • effect
  • more
  • less

Frage 8

Frage
Dopamine pathways: Dopamine produced in the substantia nigra compacta is released in the [blank_start]dorsal striatum[blank_end]. Dopamine produced in the [blank_start]ventral tegmental area (VTA)[blank_end] is released in the [blank_start]nucleus accumbens (ventral striatum)[blank_end] and the [blank_start]frontal cortex[blank_end].
Antworten
  • dorsal striatum
  • ventral tegmental area (VTA)
  • nucleus accumbens (ventral striatum)
  • frontal cortex
  • globus pallidus
  • superior colliculus
  • thalamus

Frage 9

Frage
The activity of dopaminergic cells
Antworten
  • signals the delivery of a reward.
  • signals the reward prediction error between the expectation of a reward and its delivery.

Frage 10

Frage
[blank_start]Dopaminergic[blank_end] neurons between the substantia nigra pars [blank_start]compacta[blank_end] and the striatum can influence the plasticity of neurons between the striatum and the [blank_start]cortex[blank_end].
Antworten
  • Dopaminergic
  • GABAergic
  • compacta
  • reticulata
  • cortex
  • thalamus
  • substantia nigra pars reticulata

Frage 11

Frage
After effects of visuomotor adaptation were
Antworten
  • only observed when the arm was actively moved.
  • in both cases, whether the arm was actively or passively moved.

Frage 12

Frage
The relationship between motor commands and the resulting motion of the limb (forward model) can change due to
Antworten
  • more bone and muscle mass during development.
  • disease effecting muscle strength.
  • grasping an object.

Frage 13

Frage
There is evidence for impaired adaptation to hitting a target with a prism after a lesion to the [blank_start]cerebellum[blank_end].
Antworten
  • cerebellum
  • thalamus
  • prefrontal cortex
  • basal ganglia

Frage 14

Frage
What is this paradigm called? (Three words, no hyphens)
Antworten
  • Force field adaptation

Frage 15

Frage
Aftereffects of force field adaptation demonstrate that
Antworten
  • subjects learn an internal model of the force field and do not simply stiffen up the arm.
  • subjects learn to stiffen up their arm in the right way but don't learn an internal model of the force field.

Frage 16

Frage
Potential use of forward models:
Antworten
  • Compensating for delays in sensorimotor control
  • Anticipating and canceling sensory effects of movement
  • Learning by predicting sensory outcomes without practicing a movement
  • Estimating a current or future state of a limb

Frage 17

Frage
Dopamine is released from the midbrain (VTA and SNc) to large territories in the [blank_start]cortex[blank_end] and the [blank_start]basal ganglia[blank_end].
Antworten
  • cortex
  • thalamus
  • cerebellum
  • basal ganglia
  • brain stem
  • thalamus

Frage 18

Frage
VTA and SNc dopamine neurons are [blank_start]electrically coupled[blank_end] and fire [blank_start]synchronously[blank_end].
Antworten
  • synchronously
  • asynchronously
  • electrically coupled
  • independent

Frage 19

Frage
The inability to experience pleasure from activities usually found to be enjoyable is called [blank_start]anhedonia[blank_end]. It can be caused by antipsychotics, e.g. dopamine receptor [blank_start]antagonists[blank_end].
Antworten
  • anhedonia
  • antagonists
