“…But although overt manifestations of negative priming may depend on attentional conflicts at test, this obviously cannot change the critical effect of attention at initial exposure. Moreover, behavioral effects typically result from a balance between concurrent processes with potentially opposing positive and negative influences (Ortells, Fox, Noguera, & Abad, 2003;Neumann & DeSchepper, 1991), whereas such opposing influences might more easily be disentangled using fMRI if they affect distinct brain sites. It is possible that if repetition enhancement in the lingual cortex relate to negative priming effects, such effects might have become apparent behaviorally in some other task.…”

Attention can enhance processing for relevant information and suppress this for ignored stimuli. However, some residual processing may still arise without attention. Here we presented overlapping outline objects at study, with subjects attending to those in one color but not the other. Attended objects were subsequently recognized on a surprise memory test, whereas there was complete amnesia for ignored items on such direct explicit testing; yet reliable behavioral priming effects were found on indirect testing. Event-related fMRI examined neural responses to previously attended or ignored objects, now shown alone in the same or mirror-reversed orientation as before, intermixed with new items. Repetition-related decreases in fMRI responses for objects previously attended and repeated in the same orientation were found in the right posterior fusiform, lateral occipital, and left inferior frontal cortex. More anterior fusiform regions also showed some repetition decreases for ignored objects, irrespective of orientation. View-specific repetition decreases were found in the striate cortex, particularly for previously attended items. In addition, previously ignored objects produced some fMRI response increases in the bilateral lingual gyri, relative to new objects. Selective attention at exposure can thus produce several distinct long-term effects on processing of stimuli repeated later, with neural response suppression stronger for previously attended objects, and some response enhancement for previously ignored objects, with these effects arising in different brain areas. Although repetition decreases may relate to positive priming phenomena, the repetition increases for ignored objects shown here for the first time might relate to processes that can produce "negative priming" in some behavioral studies. These results reveal quantitative and qualitative differences between neural substrates of long-term repetition effects for attended versus unattended objects.

“…In fact, the effect might even completely reverse in such a way that responses to incongruent prime-target pairs are faster than to congruent pairs (Merikle and Joordens, 1997; Daza et al, 2002), because subjects are able to strategically use the prime information to predict the upcoming target category. Even for conscious trials this might take some time (∼400 ms), suggesting that these strategic effects take some time to build up (Ortells et al, 2003). These conscious strategic effects were recently only observed for spatially attended stimuli, but not for unattended ones (Ortells et al, 2011).…”

Here we review studies on the complexity and strength of unconscious information processing. We focus on empirical evidence that relates awareness of information to cognitive control processes (e.g., response inhibition, conflict resolution, and task-switching), the life-time of information maintenance (e.g., working memory) and the possibility to integrate multiple pieces of information across space and time. Overall, the results that we review paint a picture of local and specific effects of unconscious information on various (high-level) brain regions, including areas in the prefrontal cortex. Although this neural activation does not elicit any conscious experience, it is functional and capable of influencing many perceptual, cognitive (control) and decision-related processes, sometimes even for relatively long periods of time. However, recent evidence also points out interesting dissociations between conscious and unconscious information processing when it comes to the duration, flexibility and the strategic use of that information for complex operations and decision-making. Based on the available evidence, we conclude that the role of task-relevance of subliminal information and meta-cognitive factors in unconscious cognition need more attention in future work.

“…Subsequently, the ignored material is subject to impaired processing (Frings & Wentura, 2005;Milliken, Joordens, Merikle, & Seiffert, 1998;Neill & Kahan, 1999;Ortells, Fox, Noguera, & Abad, 2003;Tipper, 1985;Tipper & Cranston, 1985). For example, responses are slower and less accurate to a previously ignored object than to a new object.…”
