The Influence of Peripheral Preprocessing on Oculomotor Programming in a Scanning Task

People regularly interact with automation to make decisions. Research shows that reliance on recommendations can depend on user trust in the decision support system (DSS), the source of information (i.e. human or automation), and situational stress. This study explored how information source and stress affect trust and reliance on a DSS used in a baggage scanning task. A preliminary sample of sixty-one participants were given descriptions for a DSS and reported trust before and after interaction. The DSS gave explicit recommendations when activated and participants could choose to rely or reject the choice. Results revealed a bias towards self-reliance and a negative influence of stress on trust, particularly for participants receiving help from automation. Controlling for perceived reliability may have eliminated trust biases prior to interaction, while stress may have influenced trust during the task. Future research should address potential differences in task motivation and include physiological measures of stress.

Linear Scanning

A case study is presented, documenting a cognitive developmentally-based instructional protocol to teach automatic linear scanning for computer access to a 4 year, 11 month old girl with severe physical and communication disabilities who was unable to use the standard computer keyboard. The instructional protocol served to provide a bridge between the child's initial incomplete representation of the scanning task and the representation required to scan successfully, by maximizing the familiarity of the task for the child, highlighting the relevant cues, and minimizing the number of items of information to be coordinated. Results of a multiple probe design indicated the efficacy of the instructional procedures. The instructional program is discussed in light of cognitive/development theory, educational applications, and directions for future research.

The Relationship

Abstract Objective Burkhart and colleagues (2020) showed that positive screening on the Vestibular Ocular Motor Screening (VOMS) and slower King Devick scores were predictive of protracted recovery in male adolescents. The purpose of this study was to examine the relationship between positive VOMS screening and King-Devick Trial 1 scores in a similar population. Method 300 male participants age 10–18 were administered VOMS and King-Devick Trial 1 within 7-days of their injury at a specialty concussion clinic between 2017–2019. We hypothesized that slower speeds on King-Devick Trial 1 would be related to a positive screening on the VOMS (i.e. symptom provocation of +2, convergence of > 6 mm). Odds ratios were calculated to estimate the likelihood of screening positive on the VOMS among those with a King-Devick Trial 1 score above the median compared to those with a score below the median. Results Those scoring above the median on King-Devick Trial 1 (i.e. slower times) were 74% more likely to have a positive screening on the VOMS, OR = 1.74, 95% CI [1.10–2.78], p = 0.02, relative to those with a King-Devick Trial 1 above the median. Conclusions The VOMS was created to be a symptom provocation tool sensitive to concussion. However, this study demonstrated that the VOMS is also related to performance on objective visual scanning task. Specifically, adolescent males with slower scores on the King-Devick Trial 1 were more likely to have a positive screening on the VOMS.
