These results suggest that the act of worrying is sufficient to facilitate an attentional bias to threat and enhances the beneficial effects of attention to a particular spatial location.
That doesn't mean there are no effects of attention.

There's a lot of interest in these low-frequency effects of attention we could talk about later on.
So if you take cells with overlapping fields and measure synchrony, then the effects of attention are very big.

Hunger is the best spice: an fMRI study of the effects of attention, hunger and calorie content on food reward processing in the amygdala and orbitofrontal cortex.
The ignore condition always came first, in order to avoid possible carry-over effects of attention, and was followed by the attend condition.

This latter increase is in line with previous studies showing effects of attention being stronger in higher-order visual cortex than in lower-order areas28,29.
