Estimating reliability for scales or factors is an essential data analysis step in much of the research in developmental science. In this article, we demonstrate the importance of using the appropriate statistical method and underlying correlation matrix to estimate reliability for dichotomous data that represent a normally-distributed latent factor. We used an example case of three waves of ad...
Major theories for explaining the organization of semantic memory in the human brain are premised on the often-observed dichotomous dissociation between living and nonliving objects. Evidence from neuroimaging has been interpreted to suggest that this distinction is reflected in the functional topography of the ventral vision pathway as lateral-to-medial activation gradients. Recently, we obser...
A novel computational model of a preattentive system performing visual search is presented. The model processes displays of lines, reproduced from Wolfe, Friedman-Hill, Stewart, and O'Connell's (1992) and Treisman and Sato's (1990) visual-search experiments. The response times measured in these experiments suggest that some of the displays are searched serially, whereas others are scanned in pa...
Objectives To establish whether ART restorations with high-viscosity GIC have a better survival rate than restorations with resin-modified glass ionomer cement (RMGIC) and cavity preparation using conventional high-speed drill in cavities of comparable size and tooth location. Search strategy Trials were identified from a search of the database PubMed up to 16 March 2009 using the term: "atraum...
The clinical diagnosis of Complex Regional Pain Syndrome (CRPS) is a dichotomous (yes/no) categorization necessary for clinical decision-making. However, such dichotomous diagnostic categories do not convey an individual's subtle and temporal gradations in severity of the condition, and have poor statistical power when used as an outcome measure in research. This study evaluated the validity an...
