This tutorial provides a selective review of research on object-based deployment of
attention. It focuses primarily on behavioral studies with human observers. The tutorial is …

This article begins with a description of space‐and object‐based guidance of attentional
selection. It goes on to discuss the most influential, two‐rectangle, paradigm for …

Twenty-five years of research has explored the object-based attention effect using the two-
rectangles paradigm and closely related paradigms. While reading this literature, we noticed …

Our attention can be directed to specific locations in our visual field (space-based attention),
or to specific objects (object-based attention). However, object-based attention tends to be …

The contribution of object-based attentional guidance to visual processing is widely
accepted, and recent models of attentional selection now include both space-and object …

Over 30 years of research using Posner's spatial cueing paradigm has shown that selective
attention operates on representations of spatial locations, leading to space-based theories …

Crowding is the interference by surrounding objects (flankers) with target perception. Low
target-flanker similarity usually yields weaker crowding than high similarity ('similarity rule') …

Estimating reward contingencies and allocating attentional resources to a subset of relevant
information are the most important contributors to increasing adaptability of an organism …

Studies of visual object processing have long appreciated that semantic meaning is
automatically extracted. However,“semantics” has largely been defined as a unitary concept …

Object-based attention (OBA) enhances processing within the boundaries of a selected
object. Larger OBA effects have been observed for horizontal compared to vertical …
