“…3. This left hemispheric lateralization of phonological process are in agreement with behavioral (Chiarello, Kacinik, Manowitz, Otto, & Leonard, 2004;Cousin et al, 2009;Smolka & Eviatar, 2006;Waldie & Mosley, 2000) and neuroimaging (Baciu, Juphard, Cousin, & Bas, 2005;Baciu, Kahane, et al, 2001;Kareken, Lowe, Lurito, & Mathews, 2000;Simon et al, 2006;Xu et al, 2001) studies. With respect to the specific role of these regions, the left lingual (medial extrastriate) and left inferior temporal gyri may reflect early visuo-orthographic (Gaillard et al, 2006;Kronbichler et al, 2004;Valdois et al, 2006) and phonological (Xu et al, 2001) analysis.…”

“…However, for anti-phase coordination variability was greater on the left than on the right hand for LH. Correspondingly, it has been shown that in a concurrent reading task, variability of left-hand tapping was greater than for right-hand tapping (Waldie & Mosley, 2000a). Unfortunately, the latter finding is in conflict with results from Hiscock and Inch (1995) who observed that, for both RH and LH, concurrent reading increased the variability of the right hand more than the left.…”

Interest is rapidly growing in the hypothesis that natural language emerged from a more primitive set of linguistic acts based primarily on manual activity and hand gestures. Increasingly, researchers are investigating how hemispheric asymmetries are related to attentional and manual asymmetries (i.e., handedness). Both speech perception and production have origins in the dynamical generative movements of the vocal tract known as articulatory gestures. Thus, the notion of a ''gesture'' can be extended to both hand movements and speech articulation. The generative actions of the hands and vocal tract can therefore provide a basis for the (direct) perception of linguistic acts. Such gestures are best described using the methods of dynamical systems analysis since both perception and production can be described using the same commensurate language. Experiments were conducted using a phase transition paradigm to examine the coordination of speech-hand gestures in both left-and right-handed individuals. Results address coordination (in-phase vs. anti-phase), hand (left vs. right), lateralization (left vs. right hemisphere), focus of attention (speech vs. tapping), and how dynamical constraints provide a foundation for human communicative acts. Predictions from the asymmetric HKB equation confirm the attentional basis of functional asymmetry. Of significance is a new understanding of the role of perceived synchrony (p-centres) during intentional cases of gestural coordination.

“…Another explanation can be based on brain hemisphere specialization in terms of cognitive processing and motor control and competition among cognitive processes for attentional resources within a hemisphere. Numerous studies have attempted to identify the underlying factors in the effect of memory task performance on concurrent finger tapping (Kee and Bathurst 1983, Simon and Sussman 1987, Dalen and Hugdahl 1989, Towell et al 1994, Van Hoof and Van Strien 1997, Waldie and Mosley 2000. Typically tapping consistency and rate are degraded when a person is required to simultaneously recall memorized words.…”

“…These studies have been motivated by the theory that the motor activity of each hand is programmed primarily by the contralateral hemisphere (Kinsbourne and Hicks 1978). In addition to this motivation, researchers have postulated that each of the two cerebral hemispheres is responsible for processing certain types of information (Waldie and Mosley 2000), for example the left hemisphere is specialized for verbal processing in right-handed individuals (Kinsbourne and Hicks 1978). In a study by Posner et al (1988), the temporoparietal left-lateralized area was described as a good candidate for phonological processing.…”

Cervicobrachial muscle response to cognitive load in a dual-task scenario

et al. 2004

People working in an office environment often have to deal with significant cognitive workload due to the coordination of multiple, simultaneous tasks. The objective of this research was to examine the impact of cognitive load in officetype tasks on physical-stress response, using a dual-task paradigm involving a primary cognitive task and secondary typing task. The central hypothesis of this research was that altering the demands of the cognitive task would lead to a difference in physical stress-level and performance. Cognitive load was manipulated by presenting participants with three different types of cognitive tasks described in Rasmussen's (1983) taxonomy, including skill-, rule-, and knowledge-based tasks. Dependent variables examined in the study included: (1) electromyographic activity of the upper trapezius (pars descendens) and cervical erector spinae muscles, (2) performance in a secondary typing task, and (3) subjective measures of stress and cognitive workload. The results of this study revealed that the primary task causing the highest level of perceived workload also produced 61% higher muscle activity in the right trapezius, and 6 and 11% higher activity in the left and right cervical erector spinae, respectively, in comparison to muscle activity associated with the cognitive task causing the lowest perceived workload. With respect to performance, a 23% decrease was observed in typing productivity when the rule-based task was completed simultaneously vs. typing in the absence of any additional cognitive task (the baseline condition). This information may be used to better organize work activities in office environments to increase performance and reduce stress.
