Visual words that are masked and presented so briefly that they cannot be seen may nevertheless facilitate the subsequent processing of related words, a phenomenon called masked priming. [] Key Method Here we use a combination of behavioural and brain-imaging techniques to estimate the depth of processing of masked numerical primes. Our results indicate that masked stimuli have a measurable influence on electrical and haemodynamic measures of brain activity. When subjects engage in an overt semantic…
Cerebral mechanisms of word masking and unconscious repetition priming
TLDR
Within the areas associated with conscious reading, masked words activated left extrastriate, fusiform and precentral areas and reduced the amount of activation evoked by a subsequent conscious presentation of the same word.
The neural bases of subliminal priming
TLDR
Functional neuroimaging can be used to explore the neural bases of masked priming, and a simple mathematical framework is proposed that tentatively relates priming at the voxel level with the shape of the tuning curves of single neurons in the underlying tissue.
Unconscious semantic priming extends to novel unseen stimuli
Interferences of visual masks with semantic and perceptual priming effects
Many studies demonstrate that visual stimuli can be processed even if they are not consciously perceived. These studies show that unconscious stimuli can be processed – amongst other things – in
Nonconscious semantic processing of emotional words modulates conscious access.
TLDR
The results disclose two independent sources of modulation of the threshold for access to consciousness, implying that written words can receive nonconscious semantic processing.
Subliminal number priming within and across the visual and auditory modalities.
TLDR
Number priming does involve an amodal, semantic level of processing, but is also modulated by task settings, and the generalization to novel stimuli was weaker and reached significance only when considering the whole set of experiments.
Attentional Modulation of Unconscious Automatic Processes: Evidence from Event-related Potentials in a Masked Priming Paradigm
TLDR
The present results show that temporal attention to the prime is a prerequisite for obtaining masked N400 priming effects and demonstrate that unconscious automatic processes are susceptible to attentional modulation.
Do semantic priming and retrieval of stimulus-response associations depend on conscious perception?

Priming with and without awareness
In two experiments, no evidence for perception without awareness was found in a Stroop-priming task when the threshold for detecting color-word primes was measured reliably by a forced-choice
Pattern of neuronal activity associated with conscious and unconscious processing of visual signals.
TLDR
A functional magnetic resonance imaging study on a subject with unilateral damage to the primary visual cortex carried out under aware and unaware stimulus conditions points to a shift in the pattern of activity from neocortex in the aware mode, to subcortical structures in the unaware mode.
Electrophysiological evidence for temporal overlap among contingent mental processes.
TLDR
Lateralized potentials in a choice reaction task with no-go trials indicate that movement preparation can begin once partial perceptual information about a stimulus becomes available, contrary to an assumption of fully discrete models of information processing.
Conscious and unconscious emotional learning in the human amygdala
TLDR
The results indicate that the human amygdala can discriminate between stimuli solely on the basis of their acquired behavioural significance, and second, this response is lateralized according to the subjects' level of awareness of the stimuli.
Brain regions responsive to novelty in the absence of awareness.
TLDR
Brain regions responsive to novelty, without awareness, were mapped in humans by positron emission tomography and a subtle and unperceived change in the nature of the sequence resulted in increased blood flow in a network comprising the left premotor area, left anterior cingulate, and right ventral striatum.
REPETITION PRIMING AND FREQUENCY ATTENUATION IN LEXICAL ACCESS
Repetition priming effects in lexical decision tasks are stronger for low-frequency words than for high-frequency words. This frequency attenuation effect creates problems for frequency-ordered

In normal conversation, speakers translate thoughts into words at high speed. To enable this speed, the retrieval of distinct types of linguistic knowledge has to be orchestrated with millisecond
Masked Presentations of Emotional Facial Expressions Modulate Amygdala Activity without Explicit Knowledge
TLDR
This study, using fMRI in conjunction with masked stimulus presentations, represents an initial step toward determining the role of the amygdala in nonconscious processing.

We confirm that the latency of the P300 component of the human event-related potential is determined by processes involved in stimulus evaluation and categorization and is relatively independent of
