“…At short SOAs, Step 2 n priming occurs more reliably in the RVF-LH (Korsnes & Magnussen, 2007;Collins, 1999;Koivisto, 1997Koivisto, , 1998Abernethy & Coney, 1990 than in the LVF-RH (Bouaffre & Faita-Ainseba, 2007;Koivisto, 1998), for which it is reported between strongly but not weakly overlapping co-exemplars (Grose-Fifer & Deacon, 2004).…”

Contextual recall in humans relies on the semantic relationships between items stored in memory. These relationships can be probed by priming experiments. Such experiments have revealed a rich phenomenology on how reaction times depend on various factors such as strength and nature of associations, time intervals between stimulus presentations, and so forth. Experimental protocols on humans present striking similarities with pair association task experiments in monkeys. Electrophysiological recordings of cortical neurons in such tasks have found two types of task-related activity, "retrospective" (related to a previously shown stimulus), and "prospective" (related to a stimulus that the monkey expects to appear, due to learned association between both stimuli). Mathematical models of cortical networks allow theorists to understand the link between the physiology of single neurons and synapses, and network behavior giving rise to retrospective and/or prospective activity. Here, we show that this type of network model can account for a large variety of priming effects. Furthermore, the model allows us to interpret semantic priming differences between the two hemispheres as depending on a single association strength parameter.

“…In addition, some authors suggest that priming in the LH is based on automatic processing, while priming in the RH is based on controlled postlexical processing (Koivisto and Laine 2000; Koivisto and Hämäläinen 2002). Nevertheless, this interpretation has been often criticized and whether the LH or the RH hemisphere is better adapted for the automatic spreading activation of categorically related words is still a matter for discussion (Chiarello 2000; Korsnes and Magnussen 2007).…”

For more than a century, language has been assumed to be entirely dependent on left-hemisphere-based processing. However, since the early 1960s, evidence for the right hemisphere's involvement in language processing, in particular in the semantic processing of words, has emerged. At least three complementary approaches have provided evidence of this: behavioral data from neurologically intact participants, the study of brain-damaged patients and the use of neuroimaging methods. The goal of this article is to review the major evidence from these three sources concerning the nature of the right hemisphere's contribution to the semantic processing of words. Overall, the data from these studies suggest that both the right hemisphere and the left hemisphere are crucial for semantic processing, with both hemispheres being involved in different ways in the processing of semantic knowledge. processing of words (i.e. the activation of aspects of word meaning in memory; Joanette et al. 1990;Beeman and Chiarello 1998;Jung-Beeman 2005).The fact that both hemispheres seem to be involved in language comprehension raises fundamental questions about how semantic networks are functionally organized across cerebral hemispheres and, more specifically, what role each hemisphere plays in processing word meaning. One informative approach for tackling this complex issue is the use of the semantic priming paradigm, which represents an important cognitive phenomenon. This paradigm has been a focus of research in the cognitive sciences for more than 30 years because priming is one of the most basic expressions of human memory, influencing how we perceive and interpret the world. Although numerous studies have used the semantic priming paradigm, some basic questions remain unresolved. One major question is how the strength of associations between words (i.e. associated word pairs such as apple-banana vs. non-associated word pairs such as apple-cloud) affects the nature of semantic priming within and across both hemispheres.The aim of this article is to review the existing evidence regarding the nature of interhemispheric cooperation for the semantic processing of words, with an emphasis on identifying the role of the RH in this process, which remains poorly understood. A better understanding of the RH's involvement in the semantic processing of words will provide a unique opportunity to understand the neural bases of language. This review will gather evidence from three complementary approaches: behavioral data from neurologically intact participants, the study of brain-damaged patients and the use of neuroimaging methods. Since the number of publications on language processing and, more specifically, on the neurobiological bases of the semantic processing of words exceeds what can be reviewed here, this article focuses on representative papers in each area. In order to provide a better understanding of word organization in semantic memory, the mechanisms of semantic priming will be presented in the first section of this article. In the fo...

“…The right hemisphere has superior abilities in visual-spatial tasks and some specific verbal tasks (Korsnes & Magnussen, 2007;Levy & Kueck, 1986). In addition, Springer and Deutsch (1998) reported that the right hemisphere is superior to the left hemisphere in recognizing geometric shapes.…”

“…Language and speech abilities have been found to be most prominent in the left hemisphere for right-handed persons (Korsnes & Magnussen, 2007). Even when participants are asked to identify letters, responses are faster for stimuli in the right visual field/left hemisphere (RVF/LH) than when the stimuli are presented to the left visual field/right hemisphere (LVF/RH; Rizzolatti, Umilta, & Berlucchi, 1971).…”
