The Canned Beverage Sorting Task is an assessment of awareness towards inadvertent/ unintentional doping. The task has been developed based on the behavioural measures of unintentional doping by Chan et al. 2014. In short, this task measures the accuracy of individuals’ refusal to drink canned-beverages that contain banned substances and canned-beverages that do not have a clear ingredients list.

*Participants (and researchers) should read the instruction before undertaking the canned beverage sorting task.

Instructions

1.      Participants should familiarize themselves with the following pictures of canned beverages and ingredients list (stimuli): 

2.      The completion of this canned-beverage task could either be done via a computer or a smartphone with a web browser installed. During the task, a single canned beverage will be randomly selected and displayed in the middle of the screen, and participants will determine whether the presented canned beverage can be drunk (“can drink”) or not (“cannot drink”) based on the presence/absence of a clear ingredients list and/or banned substances (the correct answers are also provided above). Participants can zoom in at the canned beverage to have a closer look at the ingredients list.

3.      To categorize the stimuli, users can simply press the left or right “buttons”. 

· For computer users, please use the arrows “←” and “→” to respond.

· For smartphone users, please touch left/right boxes on the screen to respond.

4.      The canned beverage task has a practice trial to let participants familiarize themselves with the task, it will then be followed by a test trial where participants’ accuracy will be recorded.

5.       After the completion of the task, a total test score will be displayed on the screen.   A test ID will also be generated at the end of the trial so that researchers may retrieve and download the raw data (in CSV file via the home page of the tool) for record and/or further analysis. *Note: Time/date on the csv file is in the Hong Kong time zone.

How do we calculate the score in this online tool?

At the end of 32 trials, the computer will score the performance based on task accuracy, where it will calculate the sum of the correct trials. In addition to the automatically generated Canned Beverage test result, we also provide raw data for those who want to do their own scoring/data cleaning. Participants can also revisit their previous scores/spreadsheet by entering their test ID on the home page.

What does the score mean?

There can be a maximum of 32 points for the current task. A higher score denotes a more accurate determination and higher sensitivity of whether the presented canned beverage can/cannot be drunk.
