Graphicacy is an important skill in today's society; however, the interpretation of graphs proofs to be more difficult than it might seem. In this study, we focus on one specific misinterpretation, the area misinterpretation of box plots, which is caused by incorrect heuristic processing of salient features of the box plot. In this study, we tried…

The ability to track moving objects is a crucial skill for performance in everyday spatial tasks. The tracking mechanism depends on representation of moving items as coherent entities, which follow the spatiotemporal constraints of objects in the world. In the present experiment, participants tracked 1 to 4 targets in a display of 8 identical…

We investigated human performance on the Euclidean Traveling Salesperson Problem (TSP) and Euclidean Minimum Spanning Tree Problem (MST-P) in regards to a factor that has previously received little attention within the literature: the spatial distributions of TSP and MST-P stimuli. First, we describe a method for quantifying the relative degree of…

The effectiveness of using the age of references to control the exhaustivity of the reference representation in information retrieval was investigated through analysis of optimal cluster-based retrieval results. The results show that the foreground representation at its optimal level of exhaustivity is restricted to references with ages less than…

For 83 low-achieving elementary students, predictions of future performance were computed on the basis of reading and written expression data and were subsequently compared to actual data. Analyses indicated that predictions were more accurate when the data had been graphed on equal interval graphs rather than semilogarithmic charts. (Author/JDD)

Information is provided about the Delaware Educational Assessment Program and the performance of Delaware public school students as measured by a nationally-normed standardized achievement test. The Stanford Achievement Test, Eighth Edition was administered statewide, allowing comparisons with national performance and with the performance of…
