    Respiratory phases are associated with the performance on various cognitive tasks. This paper reviews behavioral and psychophysiological studies that compared the effects of inhalation and exhalation phases on perception and cognition. First, previous findings are summarized, based on psychological functions such as simple motor reaction, attention, and memory. Second, four methodical difficulties inherent in conducting such studies are discussed: choice of respiratory route (i.e., nasal vs. oral), manner of breathing (i.e., spontaneous vs. controlled), instruction on how to breathe, and manipulation of the timing of stimulus presentation. Finally, several research questions are raised to understand the relationship between respiratory phases and psychological functions.

    People often misperceive the timing of when they made a decision. Bear & Bloom (2016) asked participants to choose one white circle from a selection of five white circles and to continue watching them until a predetermined target circle changed to red, and then report whether it was their chosen circle that had changed color. The participants tended to report having chosen the target circle under a quick-change condition, which indicates that, although choices were affected by the change, people perceive having made their choice prior to the change. As new evidence supporting the postdiction of decision-making timings, the present study reports a similar effect for delays of 25–50 ms, but not for 17 ms. Moreover, the propensity for participants to report having chosen any circle by a deadline was observed to be greater at delays of 167 ms or less, which indicates that awareness of decision-making is postdictive in nature when delays are short.
