“…The seeds of the relationship between attentional processes, perception, and consciousness, were shown by Anne Treisman 7 in her 'feature integration theory' (FIT). Though this theory has received various criticisms 8 , it is still a powerful interpretative framework to understand the critical involvement of spatial attention, object spatial coding and feature binding in visual conscious experience 9 . Treismanjustified the relevance of FIT in her later works on illusory conjunctions and the symptoms experienced by patients with simultanagnosia 10 .…”

Target Detection Its Relation with Individual and Target Features

The phenomenon of target detection is studied. Explored its correlates using the technique of Narrative Overview. The phenomenon of target detection begins with the process of visual search. The saliency of the targets, acts as a factor to make the search efficient. The processing of the stimulus (using Bottom-Up and Top-Down approaches) is achieved by the engagement of personal characteristics of the individual like cognitive ability and perceptual speed. The role of these individual processes and their interaction with each other to help achieve target detection is the focus of the present study. The tests designed to measure these individual processes are also listed

“…The question of how feature binding is maintained in working memory has received a lot of attention in the psychological and neuroscientific literature (Treisman & Gelade, 1980; Treisman, 1998;Schneegans & Bays, 2019a; Treccani, 2018). These studies focused on investigating two questions: 1) whether objects are stored in the visual working memory as bound objects or separated features, and 2) whether the maintenance of binding in working memory requires the involvement of additional processing resource, for instance, attention.…”

“…In order to interact with the world efficiently, we need to not only correctly integrate different features into an object when viewing them, but also need to develop an internal representation of bound objects which remain accessible after the visual stimuli disappeared. How conjunctions of features are maintained has received a lot of attention in both the psychological and neuroscientific fields (Treisman & Gelade, 1980;Treisman, 1998;Schneegans & Bays, 2019a;Treccani, 2018). These studies largely focused on investigating on whether objects are stored in visual working memory (VWM) as bound objects or separated features.…”

Maintenance of Bound or Independent Features in Visual Working Memory is Task-dependent

Over the last decade, seemingly conflicting results were obtained regarding the question of whether features of an object are stored separately, or bound together, in working memory (WM). Many of these studies are based on an implicit assumption about a default, or fixed, mode of working memory storage. However, according to recent findings about the functional property of WM, we proposed that anticipated memory probes used in a given experiment might actually determine the format in which information is maintained in WM. In order to test this flexible maintenance hypothesis, we recorded EEG while subjects performed a delayed-match-to-sample task with and without the requirement of maintaining bound features. In two experiments, we found significant differences in EEG signals recorded in central-parietal channels between the two conditions, providing reliable evidence for such flexible maintenance.

“…How this form of generalization works is not entirely understood ( 10 ) but seems to require some form of feature binding ( 11 ) to first determine which stimuli belong together as a unified object ( 6 , 12 , 13 ) and then to link the object to some inherent value, or valence ( 14 ). Hence, feature binding appears to be essential for object-based attention ( 15 – 17 ), as neural gain has to be allocated to specific features first in order to perceive an object as a whole. At the same time, distinct stimulus features can become unbound from an attended object if they are selectively ignored ( 18 ).…”

Oscillations in the central brain of Drosophila are phase locked to attended visual features

Object-based attention describes the brain’s capacity to prioritize one set of stimuli while ignoring others. Human research suggests that the binding of diverse stimuli into one attended percept requires phase-locked oscillatory activity in the brain. Even insects display oscillatory brain activity during visual attention tasks, but it is unclear if neural oscillations in insects are selectively correlated to different features of attended objects. We addressed this question by recording local field potentials in theDrosophilacentral complex, a brain structure involved in visual navigation and decision making. We found that attention selectively increased the neural gain of visual features associated with attended objects and that attention could be redirected to unattended objects by activation of a reward circuit. Attention was associated with increased beta (20- to 30-Hz) oscillations that selectively locked onto temporal features of the attended visual objects. Our results suggest a conserved function for the beta frequency range in regulating selective attention to salient visual features.
