Chimpanzees use observed temporal directionality to learn novel causal relations.

We investigated whether chimpanzees use the temporal sequence of external events to determine causation. Seventeen chimpanzees (Pan troglodytes) witnessed a human experimenter press a button in two different conditions. When she pressed the "causal button" the delivery of juice and a sound immediately followed (cause-then-effect).

Spatial and temporal attention revealed by microsaccades.

We compared the spatial and temporal allocation of attention as revealed by microsaccades. Observers viewed several concurrent "rapid serial visual presentation" (RSVP) streams in the periphery while maintaining fixation. They continually attended to, and discriminated targets in one particular, cued stream.

Believable change: bistable reversals are governed by physical plausibility.

Planar motion flows can induce the illusory appearance of a volume rotating in depth ("depth from motion"; G. Sperling, & B. A.
