How does the stimulant medication methylphenidate pharmacologically alter brain signals to improve attention?
Methylphenidate blocks dopamine transporters, which increases extracellular dopamine, amplifies weak dopamine signals, and increases the signal-to-noise ratio to enhance task salience.

What is the phenomenon of stochastic resonance (SR) in relation to cognitive performance?
Stochastic resonance is a phenomenon where a certain amount of noise facilitates neural signal transmission, thereby increasing the signal-to-noise ratio and improving performance on cognitive tasks.

What is the core premise of the Moderate Brain Arousal (MBA) model regarding ADHD and external noise?
The MBA model postulates that brains with low levels of internal neural noise (such as in ADHD) require more external environmental noise to function at an optimal level.

How does the Moderate Brain Arousal (MBA) model explain the neural 'gain parameter' in children with ADHD?
A hypodopaminergic ADHD brain has a low gain parameter due to deficient dopamine, meaning it has low internal neural noise and thus requires higher external noise input to perform optimally.

What was the duration of the medication washout period used in this study, and why is it considered sufficient for methylphenidate?
The washout period was at least 24 hours (up to 2.5 days), which is sufficient because methylphenidate has a short half-life of 3.5 hours and is rapidly eliminated from the blood.

How was the verbal episodic memory (word recall) task structured and controlled for word characteristics?
Participants recalled lists of 12 nouns matched for word frequency, word length, and syllable number, with conditions counterbalanced using Balanced Latin squares.

How was spatial working memory span assessed in the visuo-spatial (spanboard) task?
Participants recalled dot sequences on a 4x4 grid, with sequence lengths increasing by one dot every second trial until errors were made in both trials of a given level.

What did the verbal 2-back task require the participants to do, and what variables were recorded?
Participants indicated when a word in a sequence of 30 matched the word shown two steps back. Response times and errors were recorded.

How do the state regulation deficit model and cognitive energetic theory describe ADHD difficulties?
They assert that individuals with ADHD struggle to modulate and maintain internal arousal states, especially during boring or low-load tasks, leading to regulation deficits.
