There is a robust and compelling body of evidence supporting the ergogenic and therapeutic role of creatine supplementation in muscle. Beyond these well-described effects and mechanisms, there is literature to suggest that creatine may also be beneficial to brain health (e.g., cognitive processing, brain function, and recovery from trauma). This is a growing field of research, and the purpose of this short review is to provide an update on the effects of creatine supplementation on brain health in humans. There is a potential for creatine supplementation to improve cognitive processing, especially in conditions characterized by brain creatine deficits, which could be induced by acute stressors (e.g., exercise, sleep deprivation) or chronic, pathologic conditions (e.g., creatine synthesis enzyme deficiencies, mild traumatic brain injury, aging, Alzheimer’s disease, depression). Despite this, the optimal creatine protocol able to increase brain creatine levels is still to be determined. Similarly, supplementation studies concomitantly assessing brain creatine and cognitive function are needed. Collectively, data available are promising and future research in the area is warranted.

Abstract:Human event-related potentials reflect cognitive processing, and are normally elicited by external events, such as acoustic sounds or visual stimuli. As such they provide an opportunity to study normal and abnormal brain function noninvasively, at sub-second resolution. Advances in multimedia technology permit specialists in informatics and neuropsychology to co-operate in the design and implementation of paradigms, which influence ERP components. The paper illustrates the progression from standard paradigms such as the auditory oddball, which can be used to study memory update through to contingent negative variation and three condition, visual paradigms which can be used to study cognitive and emotional responses. Data from a study investigating the comparative processing of target pictures and words illustrate how external stimuli influence the later cognitive potentials.

Abstract The brain’s relationship to essential hypertension is primarily understood to be that of an end-organ, damaged late in life by stroke or dementia. Emerging evidence, however, shows that heightened blood pressure (BP) early in life and prior to traditionally defined hypertension, relates to altered brain structure, cerebrovascular function, and cognitive processing. Deficits in cognitive function, cerebral blood flow responsivity, volumes of brain areas, and white matter integrity all relate to increased but prehypertensive levels of BP. Such relationships may be observed as early as childhood. In this review, we consider the basis of these relationships by examining the emergence of putative causative factors for hypertension that would impact or involve brain function/structure, e.g., sympathetic nervous system activation and related endocrine and inflammatory activation. Currently, however, available evidence is not sufficient to fully explain the specific pattern of brain deficits related to heightened BP. Despite this uncertainty, the evidence reviewed suggests the value that early intervention may have, not only for reducing BP, but also for maintaining brain function.

It is argued that (a) the question of ‘cultural logic’ is a valid inquiry for disciplines seeking to comprehend and compare mental processes across cultures, and (b) semiotics, as the science of studying signs and signification, is an appropriate means of approaching the question of cultural logic. It is suggested that a shift needs to be made in studying reasoning across cultures from the traditional value-oriented methods of judgment to a meaningoriented assessment. Traditional methods of cross-cultural comparison are suggested to be flawed in their attempt to develop a psychological account of why different cultural societies can draw different conclusions from ‘similar’ data, because they typically do not take into account the culturally-specific processes of ‘meaning’ and semiosis. These processes, it is argued, cause input data to develop differentially from one semiotic context to another. In other words, before reaching the cognitive processing level data is already shaped by the semiotic context, thus what is processed cognitively by two individuals in two cultural/semiotic contexts is no longer ‘the same.’ A semiotically conceived notion of cultural logic is therefore a crucial factor in any cross-cultural study of cognitive and psychological systems.

Means-end chain (MEC) theory is grounded in a cognitive approach emphasizing connections between the attributes of the product, the consequences of consumption, and the corresponding instrumentality of satisfying consumer values (Gutman, 1982). Taking this hierarchical cognitive structure into account in cross-cultural contexts can lead to deeper understanding of international consumer behavior concerning product choice and consumption decisions. To date, however, international and cross-cultural applications of MEC theory have been conducted primarily by Western researchers with Anglo-Saxon consumers as subjects (e.g., Grunert et al., 2001; Hofstede, Steenkamp, & Wedel, 1999; Mort & Rose, 2004; Overby, Gardial, & Woodruff, 2004; Russel et al., 2004; Valette-Florence et al., 2000). In addition, little attention has been paid to consumers’ cognitive processing styles, which determine different patterns of thinking, in comparative analyses of MECs among consumers from different cultural backgrounds, particularly Western and Eastern cultures. This is despite the fact that a growing corpus of cross-cultural psychology studies confirms cultural differences in styles of thinking, with Western societies characterized by analytic thinking and Eastern societies characterized by holistic thinking (Nisbett et al., 2001). We suggest that this cultural orientation in the different styles of thinking influences the hierarchical cognitive structure on which consumers from Eastern versus Western cultures base their purchase decision-making process. Thus, the question we address in this research is whether analytic versus holistic thinking affects the manner in which consumers cognitively link product attributes to different consequences and values. More precisely, this research aims to contribute to recent MEC research by examining the relation between cultural differences in cognition between Western (French) and Eastern (Korean) cultural members and their MEC linkages underlying wine purchase decision. Our research was undertaken at two different levels of cross-cultural analysis: a chronic cultural difference level and an experimental level in which either the analytic or the holistic thinking tendency is primed.
