“…This finding parallels a behavioral report demonstrating that other patients with alexia demonstrated subtle deficits in face recognition (Behrmann and Plaut, 2012). Indeed, recent studies of pure alexia have challenged the notion that this syndrome impacts solely the processing of written language, as some individuals with pure alexia have been shown to have difficulty with processing other types of complex visual stimuli (e.g., Behrmann et al, 1998;Starrfelt et al, 2010;Behrmann and Plaut, 2012) and with other language tasks (Swick et al, 2004). That said, regardless of other possible areas of deficit, HE nonetheless displays substantial reading difficulties despite partially intact neural responses to words, and that is the focus of the present report.…”

“…Neuroimaging and neuropsychological research provide conflicting evidence on the separability of the neural substrates of visual and auditory priming. Some studies indicate common brain areas (e.g., Badgaiyan, Schacter, & Alpert, 2001;Swick et al, 2004) and other research implicates separate brain regions for visual and auditory priming (e.g., Bergerbest et al, 2004;Carlesimo et al, 2004;Samuelson et al, 2000).…”

The effects of divided attention on auditory priming

The concept of attention plays a central role in theories of memory, a view supported by a long history of findings that attentional state during encoding affects later memory performance (e.g., Broadbent, 1958;Cowan, 1995;Norman, 1969). Traditional research on this topic has focused on explicit memory. More recently, researchers have addressed the relationship between attention and implicit memory, spurred by the well-documented dissociations between implicit and explicit memory (Mulligan, 2003b;Roediger & McDermott, 1993), as well as the possibility that attention during encoding may not be as crucial to implicit memory as it is to explicit memory.Several initial studies of attention and implicit memory reported the rather startling result that dividing attention reduced explicit test performance but left implicit tests unaffected (e.g., Bentin, Kutas, & Hillyard, 1995;Mulligan & Hartman, 1996;Parkin, Reid, & Russo, 1990;Russo & Parkin, 1993; SchmitterEdgecombe, 1996). Other early studies demonstrated that retention of very poorly attended stimuli is more likely to be detected with implicit than explicit memory tests (e.g., Bornstein, Leone, & Galley, 1987;Eich, 1984;Jelicic, Bonke, Wolters, & Phaf, 1992;Mandler, Nakamura, & Van Zandt, 1987;Merikle & Reingold, 1991; cf. Berry, Shanks, & Henson, 2006). Such findings imply that attention plays a larger role in encoding for explicit than implicit memory. Other researchers have gone farther in interpreting these results, proposing that implicit memory is chiefly the result of automatic encoding processes (the automaticity hypothesis, e.g., Aloisi, McKone, & Heubeck, 2004;Bentin et al., 1995;Shallice et al., 1994;Szymanski & MacLeod, 1996;Wolters & Prinsen, 1997). Much subsequent research on this topic took place under the rubric of the transfer-appropriateprocessing (TAP) view of implicit and explicit memory (e.g., Roediger, 1990;Roediger & McDermott, 1993), which provides a more differentiated view based on the distinction between conceptual and perceptual priming. This view suggests that implicit tests drawing heavily on conceptual processes should depend heavily on attention during encoding. However, perceptual priming tasks, sensitive to relatively automatic perceptual encoding processes (Roediger, 1990), should be little affected by manipulations of attention (see Mulligan & Hartman, 1996, for a more detailed development of the TAP predictions). With respect to conceptual implicit memory, these expectations are largely borne out: divided attention typically reduces conceptual priming (see Mulligan & Brown, 2003, for a review).Studies of perceptual implicit tests, however, have produced mixed results. As noted above, some of the initial studies on this topic found no effect of divided attention on perceptual priming despite robust effects on explicit memory (e.g., Mulligan & Hartman, 1996;Russo & Parkin, 1993). For example, in Mulligan and Hartman (1996), study words were presented visually under one of two conditions. In the full attention (FA) condition, th...

“…Concerning auditory repetition priming, neuroimaging studies have previously failed to confirm the involvement of the auditory cortex (Badgaiyan et al, 1999(Badgaiyan et al, , 2001Carlesimo et al, 2004;Orfanidou et al, 2006) (for neuropsychological evidence, see also Swick et al, 2004). However, a large body of behavioral evidence suggests that this phenomenon is indeed mediated by perceptual representations (Schacter and Church, 1992;Church and Schacter, 1994), i.e., by the auditory cortex.…”

Previous neuroimaging studies in the visual domain have shown that neurons along the perceptual processing pathway retain the physical properties of written words, faces, and objects. The aim of this study was to reveal the existence of similar neuronal properties within the human auditory cortex. Brain activity was measured using functional magnetic resonance imaging during a repetition priming paradigm, with words and pseudowords heard in an acoustically degraded format. Both the amplitude and peak latency of the hemodynamic response (HR) were assessed to determine the nature of the neuronal signature of spoken word priming. A statistically significant stimulus type by repetition interaction was found in various bilateral auditory cortical areas, demonstrating either HR suppression and enhancement for repeated spoken words and pseudowords, respectively, or word-specific repetition suppression without any significant effects for pseudowords. Repetition latency shift only occurred with word-specific repetition suppression in the right middle/posterior superior temporal sulcus. In this region, both repetition suppression and latency shift were related to behavioral priming. Our findings highlight for the first time the existence of long-term spoken word memory traces within the human auditory cortex. The timescale of auditory information integration and the neuronal mechanisms underlying priming both appear to differ according to the level of representations coded by neurons. Repetition may "sharpen" word-nonspecific representations coding short temporal variations, whereas a complex interaction between the activation strength and temporal integration of neuronal activity may occur in neuronal populations coding word-specific representations within longer temporal windows.
