Commentary: Covert or overt? Depends on how hard you look

The elephant of patient safety: what you see depends on how you look.

Are eyes special? It depends on how you look at it.

Recent behavioral data have shown that central nonpredictive gaze direction triggers reflexive shifts of attention toward the gazed-at location (e.g., Friesen & Kingstone, 1998). Friesen and Kingstone suggested that this reflexive orienting effect is unique to biologically relevant stimuli. Three experiments were conducted to test this proposal by comparing the attentional orienting produced by...

How you feel on the inside could be affecting how you look on the outside.

Covert and overt voluntary attention: linked or independent?

Recent evidence indicates that reflexive shifts in spatial attention with eye movements (overt orienting) and without eye movements (covert orienting) can be dissociated [J. Exp. Psychol. Hum. Percept. Perform., in press]. Here, we show that a similar dissociation exists for voluntary shifts in overt and covert attention. Our study is consistent with general theories of attention that assume bo...

Intracellular actin-based transport: how far you go depends on how often you switch.

Intracellular molecular motor-driven transport is essential for such diverse processes as mitosis, neuronal function, and mitochondrial transport. Whereas there have been in vitro studies of how motors function at the single-molecule level, and in vivo studies of the structure of filamentary networks, studies of how the motors effectively use the networks for transportation have been lacking. W...
