“…Encoding will also occur in CnTf, simply because the displays are novel. Previous research from our lab has shown that occipital cortex can be more activated in repeated displays in contextual cueing, although this was rather retrieval-related activation in this former study [51]. …”

We investigated fMRI responses to visual search targets appearing at locations that were predicted by the search context. Based on previous work in visual category learning we expected an intrinsic reward prediction error signal in the putamen whenever the target appeared at a location that was predicted with some degree of uncertainty. Comparing target appearance at locations predicted with 50% probability to either locations predicted with 100% probability or unpredicted locations, increased activation was observed in left posterior putamen and adjacent left posterior insula. Thus, our hypothesis of an intrinsic prediction error-like signal was confirmed. This extends the observation of intrinsic prediction error-like signals, driven by intrinsic rather than extrinsic reward, to memory-driven visual search.

“…Medial temporal structures are involved in working memory maintenance along with the ventral occipitotemporal cortex (Ranganath & D'Esposito, 2005). fMRI activation in these same structures is modulated by contextual cueing (Geyer, Baumgartner, Müller, & Pollmann, 2012;Manginelli, Baumgartner, & Pollmann, 2013). The present data suggest that the contextualcueing-related activation in these areas may be related to the retrieval and maintenance of learned memory cues during search.…”

In a series of experiments, we investigated the dependence of contextual cueing on working memory resources. A visual search task with 50 % repeated displays was run in order to elicit the implicit learning of contextual cues. The search task was combined with a concurrent visual working memory task either during an initial learning phase or a later test phase. The visual working memory load was either spatial or nonspatial. Articulatory suppression was used to prevent verbalization. We found that nonspatial working memory load had no effect, independent of presentation in the learning or test phase. In contrast, visuospatial load diminished search facilitation in the test phase, but not during learning. We concluded that visuospatial working memory resources are needed for the expression of previously learned spatial contexts, whereas the learning of contextual cues does not depend on visuospatial working memory.

“…Working memory provides the repository where irrelevant information can be filtered out and meaningful information can be extracted before it is processed into long-term memory (Baddeley & Hitch, 1974;Manginelli, Langer, Klose, & Pollmann, 2013). Working memory may also be involved in maintaining and retrieving the repeated spatial layout template for later visual search facilitation (Manginelli, Baumgartner, & Pollmann, 2013). Under high working memory loads, contextual cueing effects can be significantly reduced or even eliminated (Annac et al, 2013;Travis, Mattingley, & Dux, 2013).…”
