Differential observing responses (DORs) are additional response requirements used to promote orientation to a stimulus in a discrimination task. Farber and Dickson (2023) recently provided a DOR taxonomy, and these authors reported that no prior research has compared the effects of distinct DOR requirements. We compared the effects of two DOR…

Humans perceptually extract quantity information from our environments, be it from simple stimuli in isolation, or from relational magnitudes formed by taking ratios of pairs of simple stimuli. Some have proposed that these two types of magnitude are processed by a common system, whereas others have proposed separate systems. To test these…

The goal of the experiment was to examine the relevance of a new French web-based assessment, Tinfolec (Test INFOrmatisé d'évaluation de la LECture), the aim of which is to evaluate the reading abilities of children in primary grades. The participants were 1,016 children from Grades 2 to 5. They completed the five tasks of Tinfolec designed to…

Children with developmental dyslexia (DD) may differ from typical readers in aspects other than reading. The notion of a general deficit in the ability to acquire and retain procedural ("how to") knowledge as long-term procedural memory has been proposed. Here, we compared the ability of elementary school children, with and without…

Variation in baseline controlling relations is suggested as one of the factors determining variability in stimulus equivalence outcomes. This study used single- comparison trials attempting to control such controlling relations. Four children learned AB, BC, and CD conditional discriminations, with 2 samples and 2 comparison stimuli. In Condition…
