Development and Validation of a Shortened Language-Specific Version of the UNRAVEL Placekeeping Ability Performance...

The current study aimed to develop a shortened language-specific (Polish) version of the UNRAVEL task  (Altmann, Trafton, & Hambrick, 2014) and to verify whether the adaptation yields valid and reliable data about placekeeping ability. Since the original procedure is intended to investigate task performance referring to placekeeping operations under conditions of task interruptions, we used this tool in the context of a multitasking situation. The adopted version differs from the original in that we reduced the number of steps in the procedure and changed the rules set, using an acronym WINDA (a word meaning elevator in Polish). Participants were asked to try to keep their place in the WINDA sequence, make a two-alternative forced choice regarding one feature of a presented stimulus, and to continue the task after the interruption at the place where they had left off. Similarly to the original task, reliability of sequence errors was high, suggesting that the WINDA task is suitable for measuring individual differences in placekeeping performance. The results suggest that the adaptation process that we employed to create the WINDA task can be utilized to generate other language adaptations of this tool (characterized by different levels of difficulty) targeted at specific subject groups.
