Abstract. When two dot arrays are briefly presented, separated by a short interval of time, visual short-term memory of the first array is disrupted if the interval between arrays is shorter than 1300-1500 ms ( Brockmole, Wang, & Irwin, 2002 ). Here we investigated whether such a time window was triggered by the necessity to integrate arrays. Using a probe task we removed the need for integration but retained the requirement to represent the images. We found that a long time window was needed for performance to reach asymptote even when integration across images was not required. Furthermore, such window was lengthened if subjects had to remember the locations of the second array, but not if they only conducted a visual search among it. We suggest that a temporal window is required for consolidation of the first array, which is vulnerable to disruption by subsequent images that also need to be memorized.

Much work has been done to characterize domain-specific brain networks associated with reading, but very little work has been done with respect to spelling. Our aim was to characterize domain-specific spelling networks (SpNs) and domain-general resting state networks (RSNs) in adults with and without literacy impairments. Skilled and impaired adults were recruited from the University of Alberta. Participants completed three conditions of an in-scanner spelling task called a letter probe task (LPT). We found highly connected SpNs for both groups of individuals, albeit comparatively more connections for skilled (50) vs. impaired (43) readers. Notably, the SpNs did not correlate with spelling behaviour for either group. We also found relationships between SpNs and RSNs for both groups of individuals, this time with comparatively fewer connections for skilled (36) vs. impaired (53) readers. Finally, the RSNs did predict spelling performance in a limited manner for the skilled readers. These results advance our understanding of brain networks associated with spelling and add to the growing body of literature that describes the important and intricate connections between domain-specific networks and domain-general networks (i.e., resting states) in individuals with and without developmental disorders.

Synesthesia … one day in 1997 (soon after the national gallery acquired the picture), i walked up the familiar marble stairs, crossed the rotunda, and was confronted, for the first time, by George Stubbs's Whistlejacket, the stunning, naked portrait—no groom or rider, no landscape—of a chestnut Arabian stallion. I smelled the stable, horse manure, and leather, and I had the thrill of knowing what was happening inside my skull. How the attention response had sent a cloud of fire leaping through my brain, tugging on associated traces, map on map of firing and partially firing neurons springing back into existence (never the same twice, yet continuous with my earliest childhood and the millions of years before that). Surprise and the power of the artist were making me read internal stimulus as external: recall had become once again perception (McCrone 194-217). This is an iconic memory for me. It holds, packed down and ready to unfold, both the direction my work has taken through my career and the context of that work: my own life and times; the history that made me; the Next Big Thing in science; and my privileged, difficult position as a science fiction writer, an arts graduate, and a woman.
