The effects of tDCS on object perception: A systematic review and meta-analysis.

Transcranial direct current stimulation (tDCS) is a novel, non-invasive method of modulating brain activity by applying electrical current directly to the scalp. While the effects of tDCS are more established in the clinical setting, its influence on cognition, specifically object perception, is less clear. The goal of this systematic review was to investigate whether object perception can be improved by tDCS, and if so, under what conditions.

Cross-modal masked priming of the tritone paradox.

The tritone paradox is a musical illusion consisting of pairs of octave-ambiguous tones that could be heard as ascending or descending in pitch. This study investigated whether perception of the tritone paradox can be unconsciously influenced by a masked visual prime - specifically, a musical notation. In Experiment 1, participants were first given a "neutral" masked prime (an image of an empty music staff) to assess baseline perception.
