“…An advantage in accuracy when there was a match of visual hemifield presentation at study and test has also been found in previous studies that used yes/no recognition paradigms [32,35,36]. However, these studies did not separate explicit and implicit memory or monitor response confidence, so it is unclear whether effects were due to implicit memory for the information.…”

Implicit Recognition Based on Lateralized Perceptual Fluency

In some circumstances, accurate recognition of repeated images in an explicit memory test is driven by implicit memory. We propose that this “implicit recognition” results from perceptual fluency that influences responding without awareness of memory retrieval. Here we examined whether recognition would vary if images appeared in the same or different visual hemifield during learning and testing. Kaleidoscope images were briefly presented left or right of fixation during divided-attention encoding. Presentation in the same visual hemifield at test produced higher recognition accuracy than presentation in the opposite visual hemifield, but only for guess responses. These correct guesses likely reflect a contribution from implicit recognition, given that when the stimulated visual hemifield was the same at study and test, recognition accuracy was higher for guess responses than for responses with any level of confidence. The dramatic difference in guessing accuracy as a function of lateralized perceptual overlap between study and test suggests that implicit recognition arises from memory storage in visual cortical networks that mediate repetition-induced fluency increments.

“…The results suggest that the memory traces left by laterally presented stimuli are more easily accessible in the contralateral hemisphere, which suggests a contralateral organization of visual memories. than when they are presented in opposite hemifields (Banich & Shenker, 1994a;Berrini, Capitani, Della Sala, & Spinnler, 1984;Dimond, Gibson, & Gazzaniga, 1972;Kleinman & Little, 1973;Leiber, 1982;Lordahl et al, 1965). These findings, however, are not conclusive because of a common methodological issue.…”

This study investigates the hemispheric organization of visual memories. In five experiments, we examine the processes associated with the recognition of line patterns that are flashed laterally during a study phase. The first three experiments demonstrate a recognition advantage for patterns presented at test in the same (rather than in the opposite) hemifield in which they were presented during a previous study phase. This difference was obtained even when stimuli were presented in different locations within the same hemifield. Experiment shows that patterns presented centrally during the recognition phase elicit ERPs that are systematically more negative over the hemisphere contralateral to the side at which they were presented during the study phase. In Experiment 5, however, we found that subjects were unable to indicate the side of initial presentation of the patterns. The results suggest that the memory traces left by laterally presented stimuli are more easily accessible in the contralateral hemisphere, which suggests a contralateral organization of visual memories.

“…For example, neuronal firing rates (e.g., Gross, Rocha-Miranda, & Bender, 1972) and amplitudes of functional magnetic resonance signals (Tootell, Mendola, Hadjikhani, Liu, & Dale, 1998) are greater following contralateral than ipsilateral visual stimulation. Also, behavioural performance in some tasks (sometimes in accuracy, not always in response time) is greater when visual comparison items are presented in the same visual fields than when they are presented in different visual fields (e.g., Dimond, Gibson, & Gazzaniga, 1972;Marsolek, Nicholas, & Andresen, 2002). Thus, lateralized presentations give the subsystems in one hemisphere advantages in guiding postvisual processing.…”

Abstractionist versus Exemplar-Based Theories of Visual Word Priming: A Subsystems Resolution

Three experiments addressed abstractionist versus exemplar-based theories of the visual representations underlying word priming. Participants first read centrally presented whole words (each displayed in all lowercase or in all uppercase letters), and then they completed laterally presented word stems (each displayed in all lowercase or in all uppercase letters). Word stem completion priming was letter-case specific (greater for same-case primed items than for different-case primed items) when stems were presented directly to the right cerebral hemisphere but not when stems were presented directly to the left cerebral hemisphere. This interaction was not influenced by the typicality of the test stems, but it was observed only for stems composed of letters with visually dissimilar lowercase and uppercase structures (e.g., bea/BEA) and not for stems composed of letters with visually similar lowercase and uppercase structures (e.g., sco/SCO). In contrast, cued recall was letter-case specific when similar-case or dissimilar-case stems were presented directly to the right hemisphere. Results do not support strongly abstractionist or exemplar-based theories. Instead, they suggest a resolution to these differing perspectives: Relatively independent neural subsystems operate in parallel to underlie abstract-category and specific-exemplar priming of word forms.
