Unit quiz: Networks, habits and the appraisal of evidence

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 person with damage to the thalamus and underlying tracts shows comprehension and repetition problems resembling the profile associated with a posterior temporal cortical lesion. What is the correct inference?That the behavioural syndrome does not identify a single cortical site, because interrupting a distributed network at another point can produce a similar picture.That the thalamus is the comprehension centre, since damaging it produces the comprehension profile.

Question 2

A commercial training programme reports an increase in frontal grey matter in 18 participants per group and concludes that it raises intelligence. Which critique is strongest?The finding is acceptable because frontal cortex supports intelligence, so a frontal change must improve it.The study is underpowered for small effects, the structural measure cannot identify a cellular change, and broad transfer was not established.

Question 3

After extensive training, a person continues to perform a routine at the same rate when the reward that originally motivated it is made irrelevant, while a less trained person slows markedly. What does the contrast show?The extensively trained behaviour is under stimulus control and relatively insensitive to outcome value, which is the operational definition of habit.The extensively trained person values the reward more, because persistence shows stronger motivation.

Question 4

A press release states that a study 'shows social media use causes attention problems', and the study compared attention scores across groups reporting different levels of use. What should the reader record?That the release can be trusted because institutional press offices check their wording with the authors.That the causal verb exceeds the design, which supports an association, and that direction and third factors remain open.

Question 5

A preregistered randomised trial with 20 participants per group finds no transfer of training to a broad ability measure and concludes that cognitive training does not work. How should that conclusion be graded?As inconclusive about small effects, since detecting an effect size near 0.3 would need about 175 per group, and as specific to the far-transfer measures used.As decisive, because a preregistered null result settles the question regardless of sample size.
