Letter processing in reading and spelling: Some dissociations

We describe the complex pattern of spared and impaired performance observed in a neurologically impaired subject on a number of letter processing tasks including: written letter naming, alphabetization, matching across typecase and font, oral and written spelling to dictation, and across-case letter priming. The observed dissociation in performance between the naming of written letters and the naming of letters in oral spelling as well as the dissociation between oral spelling and written spelling are shown to support a model of letter processing in which a distinction is drawn between visuo-spatial and abstract levels of letter representation. We also describe symmetrical deficits in the reading and writing of letters. These can be understood: in reading, as the result of an impairment to the processes which mediate the conversion of visuo-spatial letter representations to abstract representations, and in writing, as a deficit to the processes which negotiate the apparently reverse operation. This finding is interpreted within the context of the notions of neural and functional proximity and we raise the possibility that processes which perform distinct computations may, nonetheless, share certain computational resources.Requests for offprints should be addressed to Brenda Rapp or Alfonso Caramazza.

Investigating the mechanisms of written word production: insights from the written blocked cyclic naming paradigm

Reading and Writing - In three experiments, we examined whether similar principles apply to written and spoken production. Using a blocked cyclic written picture naming paradigm, we replicated the...     

The director of education as a leader of pedagogical issues: a study of leadership in municipal educational sector activities

The purpose of this article is to increase our knowledge about the role that directors of education play as leaders of educational activities. For its analytical framework, the study uses the qualitative research approach known as phenomenography and examines the study's findings against the rationalist perspective, against systems theory and against tight and loosely-coupled systems. On the issue of accountability, the study shows that while the directors were perceived to be accountable for mismanagement of finances, being accountable for student results was not something that worried the directors participating in this study.     

Higher-Order Comprehension Processes in Struggling Readers: A Perspective for Research and Intervention

Many children struggle to learn to read, and these difficulties can persist well into adulthood. To address this problem, researchers have investigated the processes that underlie reading. An informative body of work has thus identified basic skills (e.g., decoding, vocabulary knowledge) as necessary for successful reading. Researchers also have begun to examine comprehension skills and their contributions to the reading process. In this article we describe research from the cognitive sciences on the processes that underlie higher-order, coherence-oriented comprehension to provide an empirically and theoretically driven perspective for investigating struggling readers' difficulties. We show that this perspective is particularly beneficial in the development and assessment of instructional approaches by relating it to existing, effective interventions. Finally, we demonstrate how our own research activities have derived from this perspective and how preliminary findings extend our understanding of readers' difficulties. This work seeks to address existing challenges in the field of reading comprehension while also suggesting new ways of investigating the plight of struggling readers.     

Getting real: the authenticity of remote labs and simulations for science learning

Teachers use remote labs and simulations to augment or even replace hands-on science learning. We compared undergraduate students’ experiences with a remote lab and a simulation to investigate beliefs about and learning from the interactions. Although learning occurred in both groups, students were more deeply engaged while performing the remote lab. Remote lab users felt and behaved as though they completed a real scientific experiment. We also examined whether realistic visualizations improved the psychological and learning experiences for each lab. Students who watched live video of the device collecting their data in the remote lab felt most engaged with the task, suggesting that it is the combination of the realistic lab and realistic video that was of the greatest benefit.
