This paper investigates how humans recognize 3D faces with arbitrary orientation by measuring reaction times and proposes a model linking mental rotation to alpha brainwave phase.

The paper introduces the NHT model to explain how stable allocentric space perception is maintained through time-coded neural processes, supported by reaction time experiments showing eccentricity-dependent delays.

The paper tests a model of mental scaling using reaction times to recognize faces of varying sizes, finding RT increases proportional to log-scale scaling factors and consistent with depth perception.
