Here you can configure application settings:

Your task is to press the Space bar (blank, space) key as soon as you notice this.

You have 5 seconds to react after skipping the clock.

At the bottom of the screen, the time remaining until the end of the task will be displayed.

As the demo mode is on, the screen will change the background color to red just before each target signal (stimulus) appears. After the target signal appears, the background color will be green until the maximum allowed reaction time has elapsed. For real research, turn off demo mode and increase the duration of the task.

Application settings:

Task time in minutes:00:01:00

Type of stimulus: Clock will be displayed on the screen.

Target stimulus. Number of skips in seconds:

Allowed values: [-5..5]. Enter a positive value for skipping in a clockwise direction. Enter negative values for skips counterclockwise.

Maximum reaction time after skipping the clock, ie the target signal (seconds):

Warning: There may be a time lag in drawing stimuli relative to real time. It is possible that the application fails to draw a target stimulus in the last cycle (1 cycle = approximately one second). It is also possible for an application to accept a response as valid even though the maximum response time has expired. We therefore advise you to add a minimum of one cycle (one second) more than you planned. Note also that the hands of the clock never show the real time, depending on the delay of your browser compared to real time. For more information, see this link.

Probability of the target signal:1-3 in each minute

Note: If you want lower (all) probabilities to be available for selection, you must select a sufficiently large task duration in minutes

At the beginning of the task, reset clock time to zero:At the beginning of the task, the hands of the clock will be set to zero. Clock hands will not display the correct time

The numbers on the clock:The numbers on the clock are displayed by your default settings

Background color during task:

Before real research, we advise the user to first work for a while in the demo mode of the program for training. In this way, you can optimally set the maximum allowed reaction time.

Demo mode:As the demo mode is on, the screen will change the background color to red just before each target signal (stimulus) appears. After the target signal appears, the background color will be green until the maximum allowed reaction time has elapsed.

Progress bar shows:The Footer and Progress bar will not be visible

Your browser probably doesn't have support for the Web Storage Object or access to the Storage Object is disabled. Check your browser settings. In some browsers (example: IE11) Storage Object is not enabled when accessed in a local file (offline).

Target stimulus detection

Description:
Target = Ordinal number of the target stimulus.
Correct = Reacted correctly with the SPACE key within the allowed time interval.
RT = Reaction time in milliseconds (ms).
Total-target = Total number of target stimuli in the whole task.
Incorrect = The number of target stimuli for which the SPACE key is not pressed within the allowed time interval.
Errors-space = SPACE key pressed outside the allowed reaction time interval (false-alarm or too late reaction).
Errors-other = Total number of presses of all other keys (except SPACE) during the task.
Note:Time measurement precision (RT) might get rounded and vary depending on browser settings. For all Non-Real-time operating systems, a conservative assumption of the ordinal scale of measurement applies.

Frequencies

Target stimuli with correct reaction (percentage) is shown in green. Target stimuli with no correct reaction (percentage) is shown in red. Total range: 0%-100%.
