Visual stimuli as well as transcranial magnetic stimulation (TMS) can be used: (1) to suppress the visibility of a target and (2) to recover the visibility of a target that has been suppressed by another mask. Both types of stimulation thus provide useful methods for studying the microgenesis of object perception. We first review evidence of similarities between the processes by which a TMS mas...

Ideomotor theories of human action control assume that performing a movement leads to the automatic integration of the underlying motor pattern with codes of its perceptual consequences. We studied the microgenesis of action-effect integration by varying the mapping of action effects upon actions from trial to trial. Experiments 1 and 2 showed that perceiving a tone repetition systematically af...

Despite a wealth of information provided by neuroimaging research, the neural basis of familiar face recognition in humans remains largely unknown. Here, we isolated the discriminative neural responses to unfamiliar and familiar faces by slowly increasing visual information (i.e., high-spatial frequencies) to progressively reveal faces of unfamiliar or personally familiar individuals. Activatio...

The "watercolor effect" is the wash of illusory color that fills in between two enclosing bichromatic contours. We studied the microgenesis of this illusion by varying the duration of the eliciting stimulus (a yellow/purple contour outlining the Mediterranean Sea) and by varying the duration of a blank interval from stimulus offset to an after-coming mask (the ISI). The illusory wash was rated ...

ABSTRACT The present study presents an exercise in a dialogue between queer theory and Dialogical Self Theory (DST) as theoretical support for research on the impacts of gender positioning LGBTI+ subjects development self. Queer inspires dialogical psychology to include its notion self radical sociability subject together with individuality that it makes possible, addition pointing importance p...

Susan Pockett presents sound arguments supporting her reinterpretations of data that Libet and co-workers used to support a number of intriguing and influential conclusions regarding the microgenesis and timing of (a) conscious sensory experience and (b) volitionally controlled motor responses. The following analysis, extending and elaborating some of her main arguments, proposes that Libet's e...

Introduction The concept of microgenesis refers to the development on a brief present-time scale of a percept, a thought, an object of imagination, or an expression. It defines the occurrence of immediate experience as dynamic unfolding and differentiation in which the ‘germ’ of the final experience is already embodied in the early stages of its development. Immediate experience typically conce...

Two successive, spatially overlapping human faces were exposed for recognition with SOAs ranging from 20 to 160 msec. The subjects effectively perceived one face, which at short SOAs mostly resembled the first stimulus and with increasing SOAs gradually shifted towards the appearance of the second, dimmer stimulus. These results replicated those from the study by Calis, et al, and extended them...
