Krupinski, Elizabeth A. – Frontline Learning Research, 2017
Visual expertise covers a broad range of types of studies and methodologies. Many studies incorporate some measure(s) of observer performance or how well participants perform on a given task. Receiver Operating Characteristic (ROC) analysis is a method commonly used in signal detection tasks (i.e., those in which the observer must decide whether…

Gegenfurtner, Andreas; Siewiorek, Anna; Lehtinen, Erno; Saljo, Roger – Vocations and Learning, 2013
Understanding how best to assess expertise, the situational variations of expertise, and distinctive qualities of expertise that arises from particular workplace experiences, presents an important challenge. Certainly, at this time, there is much interest in identifying standard occupational measures and competences, which are not well aligned…

Visual Inspection of Single-Subject Data: An Empirical Analysis.
Peer reviewed Peer reviewed
Ottenbacher, Kenneth J. – Mental Retardation, 1990
Sixty-one examiners provided a rating of whether a significant change in performance of handicapped individuals occurred across the baseline and treatment phases of six graphs of hypothetical data from single-subject designs. Results revealed considerable interrater disagreement on four graphs, especially those involving change in variability or…

Visual Inspection and Statistical Analysis in Single-Case Designs.
Peer reviewed Peer reviewed
Park, Hyun-Sook; And Others – Journal of Experimental Education, 1990
The reliability of visual inspection in single-case research was investigated by determining agreement among 5 judges visually inspecting 44 graphs depicting behavior from baseline to intervention. Agreement between visual inspection and statistical procedures was determined. Implications for single-case research are discussed. (SLD)

Tindal, Gerald; And Others – 1983
The focus of this study was on the visual analysis of time series data for evaluating educational programs. Two characteristics of the data--changes in slope and variability--and two characteristics of evaluation--training in data utilization and the use of aimlines/decision rules--were manipulated. A total of 51 students and/or teachers in…

Evaluating Visual Displays by Means of Judgment and Reproduction Methods. Umea Psychological Reports No. 152.
Brannstrom, Lauritz – 1980
The spatial layout of visual displays was evaluated by means of three magnitude estimation tasks and one reproduction task. Each stimulus display consisted of 16 randomly-drawn, two-digit numbers. Six different spatial layouts, or display types, were used: systematic vs. random spatial order of numbers; regular vs. irregular boundaries of the…
