Summary of "Search strategies in practice: Influence of information and task constraints."

The practice of a motor task has been conceptualized as a process of search through a perceptual-motor workspace. The present study investigated the influence of information and task constraints on the search strategy as reflected in the sequential relations of the outcome in a discrete movement virtual projectile task. The results showed that the relation between the changes of trial-to-trial movement outcome to performance level was dependent on the landscape of the task dynamics and the influence of inherent variability. Furthermore, the search was in a constrained parameter region of the perceptual-motor workspace that depended on the task constraints. These findings show that there is not a single function of trial-to-trial change over practice but rather that local search strategies (proportional, discontinuous, constant) adapt to the level of performance and the confluence of constraints to action.

Differential brain mechanisms for processing distracting information in task-relevant and -irrelevant dimensions in visual search.

A crucial function of our goal-directed behavior is to select task-relevant targets among distractor stimuli, some of which may share properties with the target and thus compete for attentional select...

Improving the quality of systematic reviews of neurological conditions: an assessment of current practice and the development and validation of six new search strategies.

Our aim was to study the quality of the literature search strategies used in recent systematic reviews, and to develop and assess the diagnostic accuracy of six new search strategies (i.e. hedges).

Can categorical knowledge be used in visual search?

Smith, Redford, Gent, and Washburn (2005) have proposed a new categorization paradigm called the visual-search categorization task to study how display size affects categorization performance. Their r...

Negative cues lead to more inefficient search than positive cues even at later stages of visual search.

Observers can focus their attention on task-relevant items in visual search when they have prior knowledge about the target's properties (i.e., positive cues). However, little is known about how negat...

The influence of relevant and irrelevant stereoscopic depth cues: Depth information does not always capture attention.

Previous research reported ambiguous findings regarding the relationship of visuospatial attention and (stereoscopic) depth information. Some studies indicate that attention can be focused on a distin...
