Unit quiz: From memory models to defensible neuroscience claims

Check understanding, separately from reading

5 questions · 80% to pass · no timer. This quiz checks the lessons in this unit. These authored questions assess recognition and application of the taught distinctions, not professional qualification. You may review the lessons and retry. Repeat attempts reuse the question bank; a remembered answer is not proof of transfer to a new situation.

Saving a lesson records reading only. Previous lesson completions have not been converted into passing scores. You can continue reading without a pass; the assessment remains unpassed.

Question 1

A partial cue reinstates activity related to several components of an earlier event. Which statement best matches the indexing framework?The finding fits coordinated retrieval but does not uniquely prove an indexing mechanism.It proves the complete event was stored as a literal image in one hippocampal neuron.

Question 2

A task produces a sustained vascular signal while sampled spike responses adapt. What is the best first analysis?Assume the vascular signal directly proves those same neurons maintained their firing.Compare the spatial, temporal, and physiological sources of the two measurements.

Question 3

A manipulation impairs contextual recall and also makes simple stimulus discrimination harder. Which inference is premature?That the impairment isolates a memory-specific causal role.That the manipulation affected measured task performance.

Question 4

A classifier trained only on planning and recall labels an unfamiliar attention task as recall. What does the label establish?That the participant necessarily recalled an episode.Only the classifier output within an inadequate comparison set.

Question 5

A training report shows immediate improvement on practiced items but no delayed or novel-item assessment. Which claim needs additional evidence?Durable learning that transfers beyond the practiced materials.A change on the measured immediate practiced-item outcome.
