Starting from the research question about the meanings the family attributes to interactions experienced during their child's hospitalization, this study tried to understand the interaction experience of families in pediatric hospitals, as well to identify the interventions considered effective the family's perspective. Symbolic Interactionism was the theoretical framework that supported the da...

We demonstrate several parallels between interactive verbal communication and graphical communication. Experiment 1 shows that through interaction partners’ graphical representations converge, and are refined, although degree of refinement is dictated by level of interaction. Experiment 2 shows that through interaction graphical representations lose their iconicity, taking on a more symbolic fo...

The respective roles of the approximate number system (ANS) and an access deficit (AD) in developmental dyscalculia (DD) are not well-known. Most studies rely on response times (RTs) or accuracy (error rates) separately. We analyzed the results of two samples of elementary school children in symbolic magnitude comparison (MC) and non-symbolic MC using a diffusion model. This approach uses the j...

Biases are commonly seen in numerical cognition. The operational momentum (OM) effect shows that responses to addition and subtraction problems are biased in the whole-number direction of the operation. It is not known if this bias exists for other arithmetic operations. To determine whether OM exists in scalar operations, we measured response bias in adults performing symbolic (Arabic digits) ...
