Is conscious perception a series of discrete temporal frames?

Area of Science:

• Cognitive Neuroscience
• Philosophy of Mind
• Psychology

Background:

• Theories of conscious perception often propose discrete temporal frames.
• These frames are hypothesized to process information simultaneously or statically on a sub-second timescale.

Purpose of the Study:

• To review and critically evaluate proposals of discrete temporal frames in conscious perception.
• To identify and discuss the challenges and inconsistencies associated with this theoretical framework.

Main Methods:

• Literature review of existing theories and empirical evidence.
• Analysis of electroencephalography (EEG) data and perceptual flexibility studies.

Main Results:

• Evidence for specific frame durations is inconsistent.
• EEG periodicity does not directly equate to perceptual frames.
• Perceptual timing flexibility challenges the notion of rigid frames.

Conclusions:

• The discrete temporal frame theory of conscious perception faces significant theoretical and empirical challenges.
• Issues include defining frames, inter-frame connections, boundary establishment, and information buffering.
• Alternative models may be needed to explain the temporal dynamics of conscious perception.
