APK3200 Midterm QUESTIONS WITH
ANSWERS 2025/2026.
what is stimulus identification? - ✅✅detection and processing of stimulus
what is stimulus detection? - ✅✅stimulus is sensed and processed for meaning
what is part of the reaction time? - ✅✅stimulus identification, response selection,
response programming
The dorsal visual stream is primarily associated with which of the following?
color and shape
spatial localization
object identity
spatial localization & object identity - ✅✅spatial localization
The ventral visual stream is primarily associated with which of the following?
color and shape
spatial localization
object identity
spatial localization & object identity - ✅✅object identity
The dorsal pathway goes toward which lobe of the brain? - ✅✅parietal lobe
The ventral pathway goes towards which lobe of the brain? - ✅✅temporal lobe
Which part of the brain is the relay center in the thalamus for the visual pathway? -
✅✅Lateral geniculate nucleus
Attention gates visual processing via which of the following mechanisms?
- reduce processing of irrelevant stimuli in V4
- increase processing of relevant stimuli in V4
- increase processing of relevant stimuli in V1
- reduce processing of irrelevant stimuli in V1 - ✅✅reduce processing of irrelevant
stimuli in V4
When attention is directed outside the receptive field, is the receptive field affected? -
✅✅no, it seems to be unaffected
, Where is unwanted information filtered from? - ✅✅extrastriate cortex
What kind of signals do directional cues produce in the frontal and parietal? -
✅✅sustained signals
What kind of signals do directional cues produce in the occipital lobes? - ✅✅transient
What is spatial rehearsal? - ✅✅maintaining a spatial location in memory
Response is stronger and more sustained to unattended targets than to attended
targets. What type of processing is this?
- goal-directed
- stimulus-driven - ✅✅stimulus-driven (or bottom-up)
Response is stronger and more sustained to unattended targets than to attended
targets. Which region of the brain is primarily active here? - ✅✅ventral frontoparietal
network
VENTRAL = bottom-up
What region of the brain is primarily active during spatial rehearsal? - ✅✅dorsal
frontoparietal network
DORSAL = top-down
What is the difference between Goal-directed and Stimulus-driven? - ✅✅Goal-
directed (top-down): brain is directing you where to look; only let certain things through
(i.e. you tell yourself that you're going to focus on the basketball hoop)
Stimulus-driven (bottom-up): there are disruptive waves (i.e. everyone in the crowd
yelling; OR when someone else walks in as you're talking to someone, you're going to
want to look at the person coming in)
What is the difference between direct and indirect memory? - ✅✅direct - deliberate
attempt to recollect past experiences for the purpose of facilitating current information
processing
indirect - doesn't require recollection of previously processed information. Motor skills.
Which memory system can hold a massive amount of information for a brief time (<1s)?
- ✅✅Short-term sensory store
