Waiting for feedback helps if you want to know the answer: the role of curiosity in the delay-of-feedback benefit.

When participants answer a test question and then receive feedback of the correct answer, studies have shown that the feedback is more effective when it is delayed by several seconds rather than provided immediately (e.g., Brackbill & Kappy, Journal of Comparative and Physiological Psychology, 55, 14-18, 1962; Schroth, Contemporary Educational Psychology, 17, 78-82, 1992).

Appearances can be deceiving: instructor fluency increases perceptions of learning without increasing actual learning.

The present study explored the effects of lecture fluency on students' metacognitive awareness and regulation. Participants watched one of two short videos of an instructor explaining a scientific concept. In the fluent video, the instructor stood upright, maintained eye contact, and spoke fluidly without notes.

Neural correlates of processing negative and sexually arousing pictures.

Recent work has questioned whether the negativity bias is a distinct component of affective picture processing. The current study was designed to determine whether there are different neural correlates of processing positive and negative pictures using event-related brain potentials. The early posterior negativity and late positive potential were greatest in amplitude for erotic pictures.
