Research in the past decades has investigated the time course of the acquisition of physical knowledge in early development in much detail. However, few is known about the motives that actually lead infants to interact with the objects of their physical world. The research presented here investigated in two experiments if 11-month-old infants'…

We comment on Goldstein, Davidoff, and Roberson's replication and extension ("Journal of Experimental Child Psychology, 102", 219-238 [2009]) of our study of the effect of toddlers' color term knowledge on their categorical perception (CP) of color ("Journal of Experimental Child Psychology, 90", 114-141 [2005]). First, we discuss how best to…

It was concluded that drawing rules are essential and that adequate visual analysis is a necessary but not sufficient prerequisite to the production of accurate copies. (Author)

We contrast 2 theories within whose context problems are conceptualized and data interpreted. By traditional linear theory, a dependent variable is the sum of main-effect and interaction terms. By dimensional theory, independent variables yield values on internal dimensions that in turn determine performance. We frame our arguments within an…

Some infants, soon after birth, are capable of storing visual information as reflected in their ability to detect and respond to change in the immediate environment. (Author)

Testing Pollack's hypothesis that decreases in effective contour contrast (resulting from a decrease in receptor sensitivity with age or from a change in actual stimulus contrast) lead to decreases in illusion magnitude. Conclusions are questioned by Sjostrom and Pollack (PS 501 740). (Author/MB)

A series of experiments tested a recent suggestion that vertical symmetry of a stimulus display can serve as a visual diagnostic for responding "same" in a letter-matching task. The data of chief interest were same reaction times to vertically symmetric (e.g., AA) and asymmetric (e.g., LL) displays, each composed of two side-by-side uppercase…

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…

Presents a study designed to investigate the interaction between the cognitive style of field dependence/field independence and ability to recognize ground color change of a visual. A significant difference in recognition scores based on ground color change collapsing across cognitive style is reported. Implications for instructional design are…

Research on the analysis of time-series data has shown that decisions reached through visual analysis of the data may be influenced by the statistical parameters of those data. The current study investigated the statistical properties of curriculum-based time-series data for 68 elementary resource room students in four Minnesota school districts.…

The focus of this study was on the relationship between visual and statistical analyses of time series data and the degree to which characteristics of the data influenced this relationship. A total of 52 teachers took part in evaluating a series of graphs having prespecified characteristics. The independent variables manipulated included: slope,…

The Seguin Form Board Test is used to assess visual discrimination and matching and eye-hand coordination. Previous analysis has shown the vactor loadings for the same scale to differ among age levels, so the test may be measuring different abilities at different age levels. Test materials consist of ten differently shaped wooden blocks and a…
