The study of selective attention in people with profound deafness has repeatedly documented enhanced attention to the peripheral regions of the visual field compared to hearing controls. This finding emerged from covert attention studies (i.e., without eye-movements) involving extremely simplified visual scenes and comprising few visual items. In this study, we aimed to test whether this key finding extends also to overt attention, using a more ecologically valid experimental context in which complex naturalistic images were presented for 3 s. In Experiment 1 (N = 35), all images contained a single central object superimposed on a congruent naturalistic background (e.g., a tiger in the woods). At the end of the visual exploration phase, an incidental memory task probed the participants' recollection of the seen central objects and image backgrounds. Results showed that hearing controls explored and remembered the image backgrounds more than deaf participants, who lingered on the central object to a greater extent. In Experiment 2 we aimed to disentangle if this behaviour of deaf participants reflected a bias in overt space-based attention towards the centre of the image, or instead, enhanced object-centred attention. We tested new participants (N = 42) in the visual exploration task adding images with lateralized objects, as well as images with multiple object or images without any object. Results confirmed increased exploration of objects in deaf participants. Taken together our novel findings show limitations of the well-known peripheral attention bias of deaf people and suggest that visual object-centred attention may also change after prolonged auditory deprivation.

In this study，researchers will use personalized objects to assess patients' level of consciousness in chronic patients in minimally conscious state (MCS).
A subclass of DIABETES MELLITUS that is not INSULIN-responsive or dependent (NIDDM). It is characterized initially by INSULIN RESISTANCE and HYPERINSULINEMIA; and eventually by GLUCOSE INTOLERANCE; HYPERGLYCEMIA; and overt diabetes. Type II diabetes mellitus is no longer considered a disease exclusively found in adults. Patients seldom develop KETOSIS but often exhibit OBESITY.
Individuals' personal concept of their bodies as objects in and bound by space, independently and apart from all other objects.
The absence of both hearing and vision.
Methods to determine in patients the nature of a disease or disorder at its early stage of progression. Generally, early diagnosis improves PROGNOSIS and TREATMENT OUTCOME.
A system of hand gestures used for communication by the deaf or by people speaking different languages.
Hearing, auditory perception, or audition is the ability to perceive sound by detecting vibrations, changes in the pressure of the surrounding medium through time, through an organ such as the ear. Sound may be heard through solid, liquid, or gaseous mat...
