A linear cue combination framework for understanding selective attention

A linear cue combination framework for understanding selective attention.

Using a linear cue combination framework, we develop a measure of selective attention that describes the relative weight that an observer assigns to attended and unattended parts of a stimulus when making perceptual judgments. We call this measure attentional weight. We present two methods for measuring attentional weight by calculating the trial-by-trial correlation between the strength of att...

Driving and Selective Attention: a Conceptual Framework for Understanding the Role of Selective Attention in Driving

Biological motion as a cue for attention

During detection of biological motion, humans assess both the facing direction and motion direction. This study characterizes the role of these two biological cues, through use of a point-light walker, in regulating attention orientation through reaction times and accuracy ratings. We report here that the side of Gabor appearance and its tilt orientation are strongly linked through a mechanism ...

Weighted linear cue combination with possibly correlated error

We test hypotheses concerning human cue combination in a slant estimation task. Observers repeatedly adjusted the slant of a plane to 75 degrees. Feedback was provided after each setting and the observers trained extensively until their setting error stabilized. The slant of the plane was defined by either linear perspective alone (a grid of lines) or texture gradient alone (diamond-shaped text...

Choosing appropriate theories for understanding hospital reporting of adverse drug events, a theoretical domains framework approach

Adverse drug events (ADEs) may cause serious injuries including death. Spontaneous reporting of ADEs plays a great role in detection and prevention of them, however, underreporting always exists. Although several interventions have been utilized to solve this problem, they are mainly based on experience and the rationale for choosing them has no theoretical base. The vast variety of behavioral ...
