Learning and Instruction01
Schema abstraction with productive failure and analogical comparison
Among 96 ninth-grade students, comparing climate models with models from other domains improved far transfer. Both productive-failure classes learned.

Designs for learning about climate change as a complex system
Ninth-grade students who worked agent-based climate models before the lesson outscored a direct-instruction comparison on explanation and transfer.

Working memory, not processing speed, mediates fluid intelligence deficits in ADHD
In 142 young adults, the link between ADHD symptoms and fluid intelligence runs through working memory. Processing speed does not carry it.

From concrete examples to abstract relations
A CogSci abstract comparing feature-based and relational category learning, with single-trial EEG set against a decision model.

Dexamphetamine and the resting-state electroencephalogram
In 28 healthy adults, 0.45 mg/kg dexamphetamine shifts resting EEG power, and not every connectivity measure moves with it.

EEG coherence and response conflict in 7- and 9-year-olds
In 45 children recorded at seven and again at nine, flanker conflict raised theta coherence from left prefrontal to parieto-occipital cortex only at the younger age.

Response conflict in 7- and 9-year-olds: an EEG coherence study
The same seven- and nine-year-old flanker recordings, reported for a signal-processing audience as a coherence study of response conflict.

Early-onset type 1 diabetes and the young adult brain
At a mean age of 19, 31 young adults with early-onset type 1 diabetes did not differ from sibling controls in grey matter on a corrected test. Uncorrected maps suggested subtle left-hemisphere differences.

Building tasks from verbal instructions
With 66 people under EEG, extra rules in the instructions worsen a new task. Practising the extra rule is not what installs it.

Task structure complexity and goal neglect
Sixty-six children did the same three-rule matching task. The group that had first been given a fourth rule showed more goal neglect, and that neglect tracked fluid intelligence.

Intelligence and task structure complexity
Doctoral thesis on how the complexity of a task's structure produces goal neglect, and how that failure tracks fluid intelligence, in children and in adults.
