Declarative Visual Recognition Task Presentation.

<p>Declarative visual recognition task presentation: Each picture presentation began with a crosshair fixation screen, presented for 1 s to direct attention to the center of the screen. A) Individual neutral pictures were presented for 3 s in one of four quadrants of the computer screen. B) To ensure attention is being paid, participants were required to indicate whether the picture just viewed was an indoor or outdoor scene by clicking the correct button with the mouse, consequently advancing the slide show. C) During each testing session, pictures were presented mid-screen and participants were required to make “old/new” and spatial location decisions.
