Object-based attention does not automatically spread throughout an object

Attention-based Object Detection

When is an object not an object?

This paper describes an approach to designing and building Tcl extensions that can be flexibly and dynamically changed using either Tcl or C. In particular, extensions having an object-based interface are considered. This extension approach seeks to avoid the “chasm” found in migrating code from Tcl to C as it matures by freely mixing Tcl and C to create an object’s subcommands. The approach di...

How does attention facilitate object recognition?

Object recognition generally implemented in a hierarchical bottom-up process leads to a strong overlapping of populations encoding features belonging to different objects. Although experiments indicate that some scenes allow the detection of categories during very brief presentations, ambiguities in cell populations encoding features within the same receptive field limits recognition in non-seg...

Prism adaptation does not alter object-based attention in healthy participants

Hemispatial neglect ('neglect') is a disabling condition that can follow damage to the right side of the brain, in which patients show difficulty in responding to or orienting towards objects and events that occur on the left side of space. Symptoms of neglect can manifest in both space- and object-based frames of reference. Although patients can show a combination of these two forms of neglect...

Interference between object-based attention and object-based memory.

Research has shown that there are at least two kinds of visual selective attention: location based and object based. In the present study, we sought to determine the locus of spatially invariant object-based selection using a dual-task paradigm. In four experiments, observers performed an attention task (object feature report or visual search) with a concurrent memory task (object memory or spa...
