Subsequent search misses (SSM) refer to the decrease in accuracy in detecting a second target after the first target has been found in visual search task. The experiment investigated the role of intertarget distance in a dual-target visual search. The subject’s task was to find a target or targets (T letters) among distracters (L letters). In each trial there was either one high-salient target, one low-salient target, two targets (one high-salient and one low-salient) or no targets. In the dual-target condition, the targets were presented at various distances. Accuracy and reaction time for dual-target conditions and for one low-salient target condition were compared. The results revealed the role of intertarget distance in SSM. The SSM errors were observed only at particular intertarget distances. The results of the present study are discussed in relation to attentional blink studies and experiments on the dead zone of attention.

Visual search for multiple targets is especially error prone. One of these errors is called subsequent search misses (SSM) and represents a decrease in accuracy at detecting a second target after a first target has been found. One of the possible explanations of SSM errors is working memory resource depletion. Four experiments investigated the role of different kinds of working memory in SSM errors. The first experiment investigated the role of object working memory using a classical color change detection task. In the second and the third experiments, a modified change detection task was applied, using shape as the relevant feature. In the fourth experiment, a spatial working memory task was used to reveal the role of spatial working memory in SSM. The second and the third experiments revealed interference between working memory and visual search tasks, whereas in the first and the fourth experiments interference was not found. The results are discussed in terms of specific working memory deficit in SSM errors.

The results of the previous fMRI study of word frequency effect in Russian contradicts with the results obtained in fMRI studies of English speakers. Two reasons for such inconsistency may be either task specificity (verb related task vs noun related task (tasks involving verbs vs. task involving nouns) or cross-linguistic differences. The purpose of this study was to examine fMRI correlates of word frequency in Russian using object naming task. We have found that several brain regions were more activated by retrieval of low frequency than high frequency words: fusiform gyrus, inferior occipital gyrus, middle occipital gyrus, supplementary motor area, inferior frontal gyrus bilaterally, left thalamus, left insula, right cingulate gyrus. At the same time we revealed no brain areas responding more to high frequency than low frequency words. These results are consistent with the previous fMRI studies in English. The present results also indicate the possible role of parts of speech as well as possible interactions of task and word frequency in brain mechanisms for word retrieval.
