Confirmatory factor analysis supported the construct validity for a behavioral engagement factor composed of six of the original behavioral indicators: attention to instructions, on-task behavior, enthusiasm/energy, persistence, monitoring progress/strategy use, and negative affect.

As summarized by Reeves et al. (2013), the OTL construct is comprised of three components: (a) content coverage (list of topics and subtopics covered), (b) content exposure (amount of time devoted to instruction and time-on-task), and (c) content emphasis (which topics are selected for emphasis).
An experimenter described experimental trials and gave instructions on the tasks that participants performed in the trials.
The long-term goal is to develop a system that will provide real-time instructional materials based on learners' actions, so that eventually the initial set of instructions on a task can be strengthened, complemented, or overridden at different stages of training.
These studies compared the effect of two sets of instructions – variable priority instructions and fixed priority instructions – on dual-task performance following the same training.
53 In this review, only the three studies conducted by Silsupadol et al 26, 27, 52 specifically examined the impact of different instructions on dual-task postural control.
Prior to the fMRI testing session, each subject was given written and verbal instructions on the task and underwent a practice session composed of blocks of 0-back, 1-back, and 2-back.
Three were subsequently excluded; one on the basis of failure to follow task instructions, one on the basis of uncorrected visual impairment (self-reported by participant) and one due to experimenter error.
Because dual-task performance can be modified by focusing attention on one task or another, the effect of dual-task training may be influenced by the instructions provided.
