EEG/MEG, Pupillometry ARTICLES (mini-quiz 5) Flashcards
EEG and MEG: Relevance to Neuroscience & A brief introduction to the use of event-related potentials in studies of perception and attention & Pupillometry
What does pupillometry measure in psychological research?
Pupil diameter and its changes as indicators of cognitive and emotional states.
Which system is primarily responsible for controlling pupil size?
The autonomic nervous system.
What is the relationship between cognitive load and pupil dilation?
Increased cognitive load leads to pupil dilation.
How does luminance affect pupil size?
Higher luminance leads to pupil constriction.
What is the role of the locus coeruleus in pupil dilation?
It regulates pupil size through its connection to the autonomic nervous system.
Which type of processing is indicated by sustained pupil dilation?
Sustained cognitive or emotional processing.
Why is pupillometry considered a useful tool in decision-making studies?
It reflects the engagement and difficulty of decision-making processes.
How does pupil dilation relate to arousal?
Larger pupil size is associated with higher levels of arousal.
What does the pupil light reflex measure?
The automatic constriction of the pupil in response to light.
How can pupillometry be used in memory research?
It can indicate the effort and success of memory retrieval.
What is the significance of the baseline pupil size in experiments?
It serves as a reference for interpreting dilation effects.
Which neurotransmitter is most associated with pupil dilation?
Noradrenaline.
What does pupil constriction during a task suggest?
Decreased mental effort or increased relaxation.
How can individual differences in pupil response inform psychological assessments?
They reflect variability in cognitive and emotional processing.
