Why was the sorting game (LTM interfacing) run for only one session instead of two?

Some participants found the sorting activities less appealing and lacked motivation, so researchers limited the training to a single session.

What was the background of the trainers, and what were they told about the study's purpose?

Trainers were students with no background in cognitive training, blind to which group was experimental, and instructed simply to engage, motivate, and manage group dynamics.

What cognitive processes did the untrained 'counting test' measure in this study?

It measured selective attention, requiring object-based attentional control to ignore highly similar distractors and maintain a running count in working memory.

What cognitive function was assessed by the backward digit-span test?

It assessed control of working memory content, requiring participants to transform and mentally manipulate a sequence of digits to recall them in reverse order.

What test was used to evaluate executive function-switching, and what did it require?

How was reasoning tested, and what cognitive abilities does this test require?

Reasoning was tested using Raven's Progressive Matrices (RPM), which require abstract reasoning, visuospatial ability, and strategic problem-solving.

According to the literature discussed, why is productive social engagement superior to receptive social engagement for cognitive improvement?

Productive engagement involves active skill acquisition and complex activities that demand the synergy of multiple cognitive functions, whereas receptive engagement lacks active learning.

Why did the training effects show near transfer (executive control) but not far transfer (reasoning or episodic memory)?

Near transfer occurred because executive control measures shared overlapping cognitive and neural mechanisms with the card games, while reasoning and memory processes were not sufficiently engaged or trained.

What potential measurement limitation might explain the lack of training transfer to episodic memory?

A ceiling effect, as the story used in the test was short (15 units) and very few participants scored below 80% accuracy at the pretest.
