The purpose of the study is to evaluate the effects of JNJ-42847922, compared to zolpidem and placebo, on driving performance as assessed by the mean difference of standard deviation of lateral position (SDLP) after forced awakening using a validated driving simulator test at 2, 4, 6 and 8 hours post-evening dose.
This is a single center, double-blind (neither Investigator nor participant knows which treatment the participant receives), randomized (study drug assigned by chance), 3-way cross-over (the same medications provided to all participants but in different sequence), pilot study in healthy male and female participants. Participants will be randomly assigned to 1 of 6 treatment and planning sequences. The study will consist of 3 parts: Screening Phase (between 21 days and 1 day prior to the first dose administration), a 3-way crossover double-blind, single dose treatment Phase and follow-up Phase (7 to 10 days after last dose administration). The maximum study duration for each participant will not exceed 7 weeks. The double-blind crossover treatment phase will consist of 3 treatment periods separated by a washout period of at least 3 days between dosing. Participants will receive either Treatment A (2 capsules of 20 milligram \[mg\] JNJ-42847922), Treatment B (10 mg zolpidem and 1 placebo capsule) or Treatment C (2 placebo capsules) in each treatment period. Driving performance will be assessed primarily by the mean difference of standard deviation of lateral position (SDLP) from an on road driving test. Participants' safety will be monitored throughout the study.

Drive safety Score (DSS)
The DSS is a composite score of driving simulator behavior ranging from 0-10, related to actual driving performance.
Time frame: 2 to 8 hours post-dose
Subjective assessment of driving performance using visual analog scale
Participants indicated the perceived quality of their driving performance on a visual analog scale, which ranged from 0 ('I drove exceptionally poorly') to 20 ('I drove exceptionally well') around a midpoint of 'I drove normally'.
Time frame: 2 to 8 hours post-dose
Computerized Cognitive Test Battery: Detection (DET) Test
Simple reaction time task measuring processing speed; mean of the log10 transformed reaction times for correct responses (lower score = better performance).
Time frame: 2 to 8 hours post-dose
Computerized Cognitive Test Battery: Identification (IDN) Test
Choice reaction time paradigm measuring attention; mean of the log10 transformed reaction times for correct responses (lower score = better performance).
Time frame: 2 to 8 hours post-dose
Computerized Cognitive Test Battery: One Back (OBK) Test

Computerized Cognitive Test Battery: Trailmaking Test Form B (TMT-B)
TMT-B is a paper-and-pencil measure of divided attention and executive function (tracking, sequencing). The participant is instructed do draw a line to connect a set of 25 consecutively numbered and lettered circles, alternating sequentially between numbers and letters. The participant is instructed to work as quickly as possible while still maintaining accuracy. The test requires approximately 2 minutes to complete, alternate forms are available. Scores include time to completion and errors.
Time frame: 2 to 8 hours post-dose
Postural Stability Test
Postural stability will be measured by body sway meter which allows measurement of body movements in a single plane. Body sway is measured with a pot string meter (celesco) based on the Wright ataxiameter (Wright, 1971). With a string attached to the waist, all body movements over a period of time are integrated and expressed as millimeter sway. The total period of body sway measurement will be two minutes.
Time frame: 2 to 8 hours post-dose
