Who are the crowdworkers?: shifting demographics in mechanical turk
TLDR
How the worker population has changed over time is described, shifting from a primarily moderate-income, U.S. based workforce towards an increasingly international group with a significant population of young, well-educated Indian workers.

Who are the Turkers? Worker Demographics in Amazon Mechanical Turk
Amazon Mechanical Turk (MTurk) is a crowdsourcing system in which tasks are distributed to a population of thousands of anonymous workers for completion. This system is becoming increasingly popular…
Reciprocity and Retaliation in Social Games With Adaptive Agents
TLDR
A neurobiologically plausible model of action selection and neuromodulation, which adapts to its opponent's strategy and environmental conditions is introduced, based on the assumption that dopaminergic and serotonergic systems track expected rewards and costs, respectively.

Online everywhere: evolving mobile instant messaging practices
TLDR
The results demonstrate that many desktop IM practices have been appropriated by mobile laptop users, but in the face of increasingly situated computer usage and an "always online" culture, several frictions are emerging between desktop and mobile practices.

Model of the interactions between neuromodulators and prefrontal cortex during a resource allocation task
TLDR
These models of action selection with neuromodulatory systems are extended to include prefrontal structures in a resource allocation task and selective lesions demonstrate how neurmodulatory and prefrontal areas drive learning and performance of strategy selection.

Effect of neuromodulation on performance in game playing: A modeling study
TLDR
A computational model of the dopaminergic and serotonergic systems was constructed and tested in games of conflict and suggested how neuromodulatory systems can shape decision-making and adaptive learning in competitive situations.

Investigation of Biases and Compensatory Strategies Using a Probabilistic Variant of the Wisconsin Card Sorting Test
TLDR
A novel version of the traditional Wisconsin Card Sorting Test is introduced by integrating a probabilistic component into its traditional rule shifting to add uncertainty to the task, as well as the option to forage for information during any particular trial.

Allen Brain Atlas-Driven Visualizations: a web-based gene expression energy visualization tool
TLDR
By creating this web application, researchers can immediately obtain and survey numerous amounts of expression energy data from the ABA, which they can then use to supplement their work or perform meta-analysis, and it is hoped to enable ABADV across multiple data resources.
