Purpose: The experiment reported here compared two hypotheses for the poor statistical and artificial grammar learning often seen in children and adults with developmental language disorder (DLD; also known as specific language impairment). The "procedural learning deficit hypothesis" states that implicit learning of rule-based input is…

The present study examines implicit sequence learning in adult dyslexics with a focus on comparing sequence transitions with different statistical complexities. Learning of a 12-item deterministic sequence was assessed in 12 dyslexic and 12 non-dyslexic university students. Both groups showed equivalent standard reaction time increments when the…

Spatial and sequential tasks performed both independently and jointly were compared for 40 undergraduates grouped by sex and dominant hand. When both tasks were performed simutaneously, there was a significant advantage for right-handers and a slight advantage for males. This was attributed to hemispheric interference left-handers experienced.…
