When training subjects using either of the two procedures, feedback was provided on the screen following all responses (i.e., choosing the left or right comparison during MTS, and pressing or not pressing the space-bar during the pREP).
Similarly, two of the equivalence tasks (i.e., C1 [right arrow] A1, C2 [right arrow] A2) required subjects to press the space-bar, and the other two equivalence tasks (i.e., C1 [right arrow] A2, C2 [right arrow] A1) required subjects to not press the space bar during the response interval.
The computer will present the words "SPACE-BAR TASK" on the computer screen.
After each space-bar pressing task, the computer will present two nonsense syllables at the bottom of the screen.
Remember your objective is to earn as many points as possible by always trying to make the correct response on both the space-bar pressing tasks and the nonsense syllable choice tasks.
During schedule performance trials, the words "SPACE-BAR TASK" appeared in the center of the monitor screen.
During the first task of Stage 1, the nonsense syllable designated "B1" was always presented on the screen (below the words "SPACE-BAR TASK"), and subjects were required either to respond (i.e., press the space-bar) or not to respond (see [ILLUSTRATION FOR FIGURE 2 OMITTED], panel 1).
Before exposure to Test 2, participants were simply told: "This time you have to pick a nonsense syllable before you press the space-bar." That is, if a subject chose C1 and did not respond on the schedule task, the previous selection of C1 was defined as correct.
The great thing though is the keyboard dock it comes with is rather nice though, with its own battery, an extremely secure mechanism of docking the tablet, but the one little peeve was the
space-bar. We are rather used to hitting the
space-bar on the edge, but every time we did so on the Lynx, the keystroke didn't register.

Specifically, participants were instructed that they should "learn to cancel certain pictures and sounds before they are presented, by pressing the
space-bar." It is possible, therefore, that the instruction to emit the avoidance response in the presence of one stimulus but not the other may have facilitated contact with the avoidance contingency and subsequently influenced derived transformation.
The wide space-key resembles the typical computer
space-bar key, and serves well with good ergonomics.
