Спонтанное обнаружение слов в буквенных массивах в ходе поиска букв: о чем говорит процедура диссоциации процессов
Буки Веди, 2017.
Approximately twenty years ago, Laurent Itti and Christof Koch created a model of saliency in visual attention in an attempt to recreate the work of biological pyramidal neurons by mimicking neurons with centre-surround receptive fields. The Saliency Model has launched many studies that contributed to the understanding of layers of vision and the sphere of visual attention. The aim of the current study is to improve this model by using an artificial neural network as the spatial component of a model that generates saccades similar to how humans make saccadic eye movements. The proposed model uses a Leaky Integrate-and-Fire layer for temporal predictions, and replaces parallel feature maps with a deep learning neural network in order to create a generative model that is precise for both spatial and temporal shifts of attention. Our model was able to predict eye movements based on unsupervised learning from raw image input, combined with supervised learning from fixation maps retrieved during an eye-tracking experiment. The results imply that it is possible to match the spatial and temporal distributions of the model to spatial and temporal human distributions.

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.
