The visual system is exquisitely adapted to the task of extracting conceptual information from visual input with every new eye fixation, three or four times a second. Here we assess the minimum viewing time needed for visual comprehension, using rapid serial visual presentation (RSVP) of a series of six or 12 pictures presented at between 13 and 80 ms per picture, with no interstimulus interval. Participants were to detect a picture specified by a name (e.g., smiling couple) that was given just… 
Failure to detect meaning in RSVP at 27 ms per picture
This study found that when adequate masking was used, no evidence emerged that observers could detect the presence of a specific target picture, even when each picture in the RSVP sequence was presented for 27 ms, which cannot rule out the possibility that feedback processing is necessary for individual pictures to be recognized.
Discrete and continuous mechanisms of temporal selection in rapid visual streams
The authors report that the neural activity initially supports parallel processing of multiple stimuli around the target in ventral visual areas followed later by isolated activation of reported images in parietal areas.
Enhanced recognition of memorable pictures in ultra-fast RSVP
Investigating whether pictures found to be memorable in a long-term memory test are also perceived more easily when presented in ultra-rapid RSVP finds that this is the case.
High-Fidelity Visual Long-Term Memory within an Unattended Blink of an Eye
It is shown that humans have the ability to store at high speed detailed copies of current visual stimulations in long-term memory independently of current intentions and the current attentional focus.
Dense sampling reveals behavioral oscillations in rapid visual categorization
The results indicate that oscillatory effects are not mere fringe effects relevant only with simple stimuli, but are resultant from the core mechanisms of visual processing and may well extend into real-life scenarios.
Ultrafast scene detection and recognition with limited visual information
The results offer only limited support for the Fast M hypothesis, suggesting instead that feedforward processing is able to activate conceptual representations without complementary reentrant processing.
Banana or fruit? Detection and recognition across categorical levels in RSVP
The results of this study are interpreted as being consistent with the claim that the basic level is usually the entry level for object perception.
Ultra-Rapid serial visual presentation reveals dynamics of feedforward and feedback processes in the ventral visual pathway
This work used ultra-rapid serial visual presentation to suppress sustained activity that blurs the boundaries of processing steps, enabling it to resolve two distinct stages of processing with MEG multivariate pattern classification.

The results, taken together with those in 1969 of Potter and Levy for slower rates of sequential presentation, suggest that on the average a scene is understood and so becomes immune to ordinary visual masking within about 100 msec but requires about 300 msec of further processing before the memory representation is resistant to conceptual masks from a following picture.
Effects of task requirements on rapid natural scene processing: from common sensory encoding to distinct decisional mechanisms.
A masking procedure was used to compare 4 tasks in which sensory, decisional, and motor aspects were systematically varied to suggest that the initial part of the sensory encoding relies on common and parallel processing across a large range of tasks, whether participants have to categorize the image or locate a target in 1 of 2 scenes.

Recognition memory for pictures of both durations showed a striking ability of observers to process pictures selectively, and the possible role of these effects in visual scanning are discussed.
The Characteristics and Limits of Rapid Visual Categorization
It is argued that rapid object categorizations in natural scenes can be done without focused attention and are most likely based on coarse and unconscious visual representations activated with the first available (magnocellular) visual information.
Getting beyond the serial/parallel debate in visual search: a hybrid approach
The question of whether visual search involves at least one item-by-item serial processing stage or whether instead it is an entirely parallel process has been debated for decades, Recently,
Recognition memory for briefly presented pictures: the time course of rapid forgetting.
Both the passage of time and test interference (but not presentation interference) led to forgetting, and the brief persistence of information may assist in building a coherent representation over several fixations.
Out of sight but not out of mind: the neurophysiology of iconic memory in the superior temporal sulcus
For gaps of up to 93 ms between consecutive images, human observers and neurones in the temporal cortex of macaque monkeys were found to continue processing a stimulus as if it was still present on the screen, suggesting the continued firing of neurone cells in temporal cortex may underlie iconic memory.
The Speed of Sight
The performance of single neurons was comparable to that of humans and responded in a similar way to changes in presentation rate and the implications for the role of temporal cortex cells in perception are discussed.
