Thanks to everyone who voted! So it looks like the fork is bistable for about 65% of people. Anyone have any ideas what about the image makes it bistable?.

Does your perception of which way the tines are pointing switch back and forth?.

What do you see? Fork tines up (toward the sky) or down (toward the plate)?.

I was making faces with my food (as one does) and noticed something odd . are the fork tines pointing up or down??. As a vision scientist, I feel the need to collect some data on this . 2 polls below, please tell me what you see!

My review of temporal attention is out in @NatRevPsych! It covers key conceptual issues, data, and models in the field of visual temporal attention, and I hope it will be useful to both experts and those new to the topic.Web: PDF:

2. Temporal attention enhanced stimulus representations ~250 ms after stimulus onset, unexpectedly, in fronto-cingulate cortex. We speculate that sending target information here may protect it from interference in visual cortex by a subsequent stimulus.

The human brain receives a continuous stream of input, but it faces significant constraints in its ability to process every item in a sequence of stimuli. Voluntary temporal attention can alleviate...

1. We found a periodic modulation of visual cortical activity before an attended time. This modulation (~2 Hz) anticipated predictable target times and shifted in phase depending on the precise timing of attention.

We can often anticipate the precise moment when a stimulus will be relevant for our behavioral goals. Voluntary temporal attention, the prioritization of sensory information at task-relevant time...

Two new preprints on the neural mechanisms of temporal attention! We used MEG to study how people selectively attend to items at specific time points within a sequence, when temporal predictability is controlled. With @JiatingZhu @kan_tian @carrasco_lab @djheeger 🧵.

What does “probabilistic perception” mean to you?.
Help @rndenison, @De_dicto, Janneke Jehee and myself by filling this 2-minute survey: We want to know how people understand several key concepts related to "probabilistic perception" as part of our @CogCompNeuro adversarial collaboration. RTs appreciated!.
