Determining whether attentional control settings are inclusive or exclusive

Attentional capture with rapidly changing attentional control settings.

The classic theory of spatial attention hypothesized 2 modes, voluntary and involuntary. Folk, Remington, and Johnston (1992) reported that even involuntary attention capture by stimuli requires a match between stimulus properties and what the observer is looking for. This surprising conclusion has been confirmed by many subsequent studies. In these studies, however, the observer typically look...

Stimulus-driven attentional capture and attentional control settings.

Jonides and Yantis (1988) found that abrupt-onset singletons capture attention in visual search when onset is orthogonal to the target's defining and reported attributes and that color and brightness singletons do not. They concluded that abrupt onset may be unique in capturing visual attention. Folk, Remington, and Johnston (1992) challenge this conclusion and argue that (a) the occurrence of ...

Family practice: exclusive, inclusive, or--heaven forbid--both?

Rapid communication Complex attentional control settings

The visual system prioritizes information through a variety of mechanisms, including “attentional control settings” that specify features (e.g., colour) that are relevant to current goals. Recent work shows that these control settings may be more complex than previously thought, such that participants can monitor for independent features at different locations (Adamo, Pun, Pratt, & Ferber, 2008...

Non-inferiority trials: determining whether alternative treatments are good enough.

New treatments that are potentially as effective as existing treatments are increasingly being developed, some of which may be preferred because of lower cost, fewer side effects, easier administration or less harm. Non-inferiority trials attempt to establish whether or not a new treatment -- drug or non-drug -- is no worse than an established treatment for which efficacy has been determined in...
