Traditionally, inattentional blindness refers specifically to the failure to notice unexpected objects. Inattentional amnesia.  While admitting to possible ambiguities in methodology, Mack, one of the foremost researchers in the field, holds strongly that inattentional blindness stems predominantly from a failure of attentional capture.  Evidence through research on inattentional blindness contemplates that it may be possible that inattentional blindness reflects a problem with memory rather than with perception. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Sustained inattentional blindness tasks induce these attentional demands by tasking subjects with tracking one set of moving objects and ignoring the rest.

Consciousness and Cognition (2010), doi:10.1016/j.concog.2010.09.013, Martinez-Conde, S., & Macknik, S. L. (2008). In Psych Terms we attempt to describe and define potentially confusing psychological terms while illustrating examples to best visualize it.  It seems that inattentional blindness can be explained by both memory and perceptual failures because in experimental research participants may fail to report what was on display due to failures in encoded information (memory) or a failure in perceptually processed information (perception).. Questions 2) and 3) were control questions, and no one falsely reported these as true. Inattentional Blindness - Magic Singh. The unnoticed stimuli in a visual scene are attended to and consciously perceived, but are rapidly forgotten rendering them impossible to report. (1998). More specifically, there is disagreement in the literature about exactly how much processing of a visual scene is completed before selection dictates which stimuli will be consciously perceived, and which will not (i.e. Despite similarities, each type of blindness has a unique background and distinct theoretical implications. This suggests that if one has had much experience with the stimuli in a visual field, they are more likely to consciously perceive the unexpected object. In neglect, patients with lesions to the parietal cortex fail to respond to and report stimuli presented on the side of space contralateral to damage.  Inattentional blindness refers to an inability to identify an object all together where as change blindness is a failure to compare a new image or display to one that was previously stored in memory.. Becklen, R., & Cervone, D. (1983).

This particular hypothesis bridges the gap between the early and late selection theories.  However the debate arises whether this inattentional blindness was due to memory or perceptual processing limitations. Here, participants were asked to complete a memory task involving either the simple maintenance of verbal stimuli, or the rearrangement of this material, a more cognitively demanding exercise.

That is, if the current task is attentionally demanding and its processing exhausts all the available resources, little remains available to process other non-target stimuli in the visual field. Yantis, S. (1999). Psychonomic Bulletin & Review, 14(1), 142-147. Magic and fixation: Now you don't see it, now you do. , Studies investigating the effect of expectation on episodes of inattentional blindness have shown that once observers are made aware of the importance of the to be presented stimuli, for example stating that one will later be tested on it, the phenomenon essentially disappears. Inattentional blindness is the phenomena where we miss things right in front of us because we did not expect to see them and we are focused on something else entirely. This phenomenon can effect anyone and isn't caused by any known cognitive deficits. Scientific American, December 2008, 72-79. Wolfe, J.M.

It is the unexpected nature of said stimulus that differentiates inattentional blindness from failures of awareness such as attentional failures like the aforementioned attentional blink.
