Psychological constructs in driving automation: a consensus model and critical comment on construct proliferation

As automation in vehicles becomes more prevalent, the call for understanding the behaviour of the driver while driving an automated vehicle becomes more salient. Although a variety of driver behaviour models exist, and various psychological constructs have been said to be influenced by automation, an empirically testable psychological model of automated driving has yet to be developed. Building upon Stanton and Young's model of driving automation, this article presents an updated model of interrelated psychological constructs. The proposed model was created based upon a systematic literature search of driving automation papers and a subsequent quantification of the number of reported links between a selected set of psychological constructs. A secondary aim of this article is to reach consensus in the use of psychological constructs regarding driving automation. Henceforth special attention is paid to resolving the issue of construct proliferation.     

Strategic item selection to reduce survey length: Reduction in validity?

The practical constraints of conducting rigorous research in applied settings often limit the ability to include well-validated, but lengthy, measures in survey designs. In the current study we tested the utility of using a strategic item selection process to alleviate this issue. We evaluated the measurement and structural model fit of items selected using a strategic item selection format and assessed the predictive validity of those abbreviated scales. We also compared fit and predictive validity to the full version item sets to assess the comparability of the abbreviated scales. Results indicated that measurement models and structural models for the a priori items produced similar fit when compared with full version items across both measures. When comparing the proportion of variance explained in the criterion, there were no differences between the strategically selected items and the full versions of the scales. We conclude that the a priori selection of items based on previous research may be a useful technique for developing short measures of psychological constructs that mitigate practical, analytical, and methodological issues associated with lengthy surveys.

Assessing knowledge of mathematical equivalence: A construct-modeling approach.

Knowledge of mathematical equivalence, the principle that 2 sides of an equation represent the same value, is a foundational concept in algebra, and this knowledge develops throughout elementary and middle school. Using a construct-modeling approach, we developed an assessment of equivalence knowledge. Second through sixth graders (N = 175) completed the assessment on 2 occasions, 2 weeks apart. Evidence supported the reliability and validity of the assessment along a number of dimensions, and the relative difficulty of items was consistent with the predictions from our construct map. By Grade 5, most students held a basic relational view of equivalence and were beginning to compare the 2 sides of an equation. This study provides insights into the order in which students typically learn different aspects of equivalence knowledge. It also illustrates a powerful but underutilized approach to measurement development that is particularly useful for developing measures meant to detect changes in knowledge over time or after intervention.
