In this brief comment we add to our previous discussion (Posner, Rothbart & Tang, 2013) of the importance of control mechanisms related to attention networks by dealing with how control influences what is learned and how wide the generalization of the learned information will be. A brain network connecting the anterior cingulate to the hippocampus appears to be important for the registration of...

The mechanisms that underlie the control of visuospatial attention determine where we look at any moment. During everyday vision, the sudden appearance of a visual stimulus can “capture” attention (Godijn & Theeuwes, 2002), which can initially facilitate orienting to that location, but later may inhibit orienting to that location. These reflexive, covert orienting behaviors have been termed Att...

The effects of aging on alerting, orienting, and executive function were examined with the use of the Attention Network Task, which combines the Posner spatial cuing task and the Eriksen flanker task into a single procedure. We found that older adults showed significantly less alerting than young adults in response to a warning cue, although there were no age differences in orienting or executi...

THE s'yndrome of glaucomatocycitic crises occupies a unique and important position among the many and heterogeneous types of glaucoma associated with uveitis. Its ominous onset, often highlighted by very high tension, is belied by the benign course it follows if treated with discretion. If the ophthalmologist is aware of this condition, he will be spared needless worry, and, more important, the...

Many conceptual change theories posit that change occurs when the learner becomes dissatisfied with the current conception (Ohlsson, 2011; Strike & Posner, 1992). A necessary component of dissatisfaction is falsifying feedback. The present experiments investigate whether participants exposed to a novel method for eliminating the ability to directly falsify a misconception will still be able to ...
