Congruency effect of presentation modality on false recognition of haptic and visual objects.

Studying a list of items related to an item that is not presented (lure item) produces a false memory. We investigated whether a haptic study/test results in false recognition and, if so, whether congruency of presentation modality between study and test reduces the false recognition. After haptic or visual study of lists of real objects that are related to a lure object, participants were asked to recognise whether the objects were presented haptically or visually. We obtained false recognition results with haptic study and/or test. False recognition was reduced when presentation and study modalities were congruent. After haptic study, false recognition was reduced in the haptic test, as compared to the visual test. In contrast, visual study always reduced visual false recognition. These results indicate that there is a general effect of retrieval cues that will reduce false recognition.

[Are the visually marked items encoded as a context?].

We examined the attentional constraints of the contextual cueing effect known to occur only for attended items. We focused on whether the items not only attended to but also inhibited afterwards yield the effect or not. We adopted a hybrid paradigm of visual marking and contextual cueing procedures. In the experiment, half the distractors preceded the others and a target for one second. The results showed the contextual cueing effect even with visually marked items. These results suggest that spatial configurations previously attended to and inhibited afterwards can be encoded as visual context.

Transfer of spatial context from visual to haptic search.

Under incidental learning conditions, spatial layouts can be acquired implicitly and facilitate visual search (contextual-cueing effect). We examined whether the contextual-cueing effect is specific to the visual modality or transfers to the haptic modality. The participants performed 320 (experiment 1) or 192 (experiment 2) visual search trials based on a typical contextual-cueing paradigm, followed by haptic search trials in which half of the trials had layouts used in the previous visual search trials. The visual contextual-cueing effect was obtained in the learning phase. More importantly, the effect was transferred from visual to haptic searches; there was greater facilitation of haptic search trials when the spatial layout was the same as in the previous visual search trials, compared with trials in which the spatial layout differed from those in the visual search. This suggests the commonality of spatial memory to allocate focused attention in both visual and haptic modalities.
