Systematic review of fNIRS studies reveals inconsistent chromophore data reporting practices.

Significance: Functional near-infrared spectroscopy (fNIRS) is unique among neuroimaging techniques in its ability to estimate changes in both oxyhemoglobin (HbO) and deoxyhemoglobin (HbR). However, fNIRS research has applied various data reporting practices based on these chromophores as measures of neural activation.

Aim: To quantify the variability of fNIRS chromophore data reporting practices and to explore recent data reporting trends in the literature.

Tracking flanker task dynamics: Evidence for continuous attentional selectivity.

Understanding the dynamics of selective attention has been a central research goal in the cognitive sciences. One account proposes that attention is unitary and increases in selectivity over time. An alternative account proposes that attention switches from a low to a high state of selectivity at a point in time when a distinct selective attention mechanism is engaged.

Probing the Neural Systems Underlying Flexible Dimensional Attention.

Flexibly shifting attention between stimulus dimensions (e.g., shape and color) is a central component of regulating cognition for goal-based behavior.

The effect of motor engagement on memory: Testing a motor-induced encoding account.

The motor system is traditionally thought to reflect the output of cognition. However, the inverse relationship of how the motor system impacts cognitive processes is less known. Work on this interaction has demonstrated that recognition memory for stimuli presented in combination with the inhibition of a prepared action is weaker compared to stimuli associated with the execution of an action (Chiu & Egner, Psychological Science, 26, 27-38, 2015a).
