If a session is ended manually and restarted, the new session log will be appended to the old one unless a new file was chosen in setup. The session ends when the predetermined time elapses or when the user ends it manually by pressing “End Session” or by closing the window. If the session type includes rewards (DRO and NCR), they are dispensed appropriately. During a session, the person observing the subject records tics by clicking the “Tic Detected” button or by pressing “T” or the space bar. Once setup is completed, the session can be started. For the NCR condition, the user is also prompted to identify the log file from a previously completed DRO session in the same subject (which provides the timing for the rewards dispensed in the NCR condition). First, the user presses “Setup” to choose which type of session is being run and to specify where the session log should be saved. The following procedure applies to both reward modes. If the hardware is set up and connected to the computer, the program can start in “link mode.” Otherwise, TicTimer can still be run in “button mode,” in which the automatic reward system is replaced by a human who presses the push button attached to the Student Trainer Interface when prompted by a beep and a red flash on the computer screen. The program can be run with or without the relay and USB cable. Python 3 was used for the log file reader script.

~6m cable with at least one pair of wires free Operation Med Associates SG-215D3 Passive Connection Panel Med Associates SG-595 Student Trainer Interface Med Associates token dispenser box, Part #ENV-703 From left to right: Token dispenser box, Student Trainer Interface with external pushbutton, box containing relay module, connected via USB cable to laptop running TicTrainer. The USB to TTL serial cable attaches to the input pins on the relay, with the USB end of the cable leaving the box to attach to the computer running TicTimer.įigure 1 shows the final assembly. The other end of the long cable connects to the two normally open pins on the relay inside of the small plastic box. The Student Trainer Interface box provides power to the token dispenser box and a remote pushbutton for manually triggering token release.
One end of the long cable enters the token dispenser and its two wires attach to the two pins in the Passive Connection Panel that, when shorted, trigger release of a reward token. The hardware allows reward tokens to be dispensed automatically to the study participant. By parsing through each line in a log file, a python script (alsoĪvailable on GitHub) can extract and summarize the key data. Each line includes the time of the event. The program writes a line to the log file for each of the following events: session started and ended, tic detected, ten seconds passed without tics, and reward dispensed. TicTimer first has the user set up the details for a session, then it runs a clock for the specified session time while writing significant events to a log file. We present the software here to facilitate its use by others. This software, and optional connection to hardware, were intended for use in the research session with the TSP as described above later in Conclusions we describe possible adaptations for other settings. Note that “automated tic counting” here refers to minimizing an expert observer’s record-keeping (simply pushing a button for each tic observed), not to machine detection of the tics. The overall motivations included not only convenience but also improvement in accuracy. We also found that the TSP required substantial investigator effort, and we started writing software with the following goals:Īutomated tic counting, timing and record-keeping Īutomated reward delivery in the DRO condition Īutomated reward delivery in the NCR condition. In the course of conducting a longitudinal study of children with Provisional Tic DisorderĦ, we found that tic suppression is seen within the first few months after a child’s first ticħ. In this paradigm, each participant is observed during several experimental conditions, baseline and differential reinforcement of zero-rate ticcing (DRO), and sometimes also verbal instruction to suppress tics and/or noncontingent reinforcement (NCR). Woods and Himle developed a tic suppression paradigm (TSP) that could be used in the experimental setting to demonstrate and quantify the effects of intentional tic suppression on tic rate in Tourette syndrome (TS) and other tic disordersĥ.
