Resumo de Recurso

Questão 1

Questão
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]
Responda
  • bell, light
  • food, shock
  • has to be learned
  • is innate

Questão 2

Questão
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].
Responda
  • extinction

Questão 3

Questão
Which is true?
Responda
  • 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.

Questão 4

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

Questão 5

Questão
Timing is crucial in BOTH classical and operant conditioning.
Responda
  • True
  • False

Questão 6

Questão
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.
Responda
  • blocking
  • conditioned
  • unconditioned

Questão 7

Questão
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.
Responda
  • effect
  • more
  • less

Questão 8

Questão
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].
Responda
  • dorsal striatum
  • ventral tegmental area (VTA)
  • nucleus accumbens (ventral striatum)
  • frontal cortex
  • globus pallidus
  • superior colliculus
  • thalamus

Questão 9

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

Questão 10

Questão
[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].
Responda
  • Dopaminergic
  • GABAergic
  • compacta
  • reticulata
  • cortex
  • thalamus
  • substantia nigra pars reticulata

Questão 11

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

Questão 12

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

Questão 13

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

Questão 14

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

Questão 15

Questão
Aftereffects of force field adaptation demonstrate that
Responda
  • 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.

Questão 16

Questão
Potential use of forward models:
Responda
  • 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

Questão 17

Questão
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].
Responda
  • cortex
  • thalamus
  • cerebellum
  • basal ganglia
  • brain stem
  • thalamus

Questão 18

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

Questão 19

Questão
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].
Responda
  • anhedonia
  • antagonists
