Detection Theory: A User's Guide is an introduction to one of the most important tools for the
analysis of data where choices must be made and performance is not perfect. In these …

Voluntary covert attention selects relevant sensory information for prioritized processing. The
behavioral and neural consequences of such selection have been extensively documented …

Block () highlights two experimental studies of neglect patients which, he contends, provide
'dramatic evidence'for unconscious seeing. In Block's hands this is the highly non‐trivial …

Covert attention not only improves performance in many visual tasks but also modulates the
appearance of several visual features. Studies on attention and appearance have assessed …

Whether attention modulates the appearance of stimulus features is debated. Whereas
many previous studies using a comparative judgment have found evidence for such an …

These decisions can be related to our most basic sensory faculties (eg,“Did I just see a light
in my rearview mirror?”) or with more complex forms of information (“Do these symptoms …

La tâche Identique-Différent présente deux stimuli en succession rapprochée et les
participants doivent indiquer s' ils sont complètement identiques ou si certains attributs …

The same-different task is a classic paradigm that requires participants to judge whether two
successively presented stimuli are the same or different. While this task is simple, with …

Signal detection models for the same–different task are presented. In contrast to the
standard approach that only considers the proportion correct, the models apply to the full …

In this article we develop an extension to the signal detection theory framework to separately
estimate internal noise arising from representational and decision processes. Our approach …
