The ‘simulation hypothesis’ is an intriguing explanation for cognition, and holds that ‘thinking consists of simulated interaction with the environment’ ([4], p.242). However, the neuroscientific proof for a simulation mechanism in the brain is indirect. In this paper we present a minimal-model approach to investigate the ‘simulation hypothesis’. Our minimal model is called ACP? and is an exten...

Fractal dimensionality (FD) measures the complexity within folds and ridges of cortical subcortical structures. We tested degree that FD might provide a new perspective on atrophy-compensation hypothesis: age or disease-related atrophy causes compensatory neural response in form increased brain activity prefrontal cortex to maintain cognition. Brain structural functional data were collected fro...

This paper discusses the relevance of the discovery of mirror neurons in monkeys and of the mirror neuron system in humans to a neuroscientific account of primates' social cognition and its evolution. It is proposed that mirror neurons and the functional mechanism they underpin, embodied simulation, can ground within a unitary neurophysiological explanatory framework important aspects of human ...

In their original report [Kunde, W., Kiesel, A., & Hoffmann, J. (2003). Conscious control over the content of unconscious cognition. Cognition, 88, 223–242] maintain that “unconscious stimuli [do not] owe their impact [.] to automatic semantic categorization” (p.223), and instead propose the action-trigger theory of unconscious priming. In a reply to our paper [Kunde, W., Kiesel, A., & Hoffmann...

The hypothesis was considered that a low fluid intake disrupts cognition and mood. Most research has been carried out on young fit adults, who typically have exercised, often in heat. The results of these studies are inconsistent, preventing any conclusion. Even if the findings had been consistent, confounding variables such as fatigue and increased temperature make it unwise to extrapolate the...

A mistake appears: the term "cross-sectional" (that appears as follows: p. 153, Abstract; p. 160 4 th paragr; p.161 2 nd paragr; p. 162, last pargr; p.163, 2 nd pargr, and p. 164, 2 nd pargr.) should actually be "correlational".

How does language impact cognition and perception? A growing number of studies show that language, and specifically the practice of labeling, can exert extremely rapid and pervasive effects on putatively non-verbal processes such as categorization, visual discrimination, and even simply detecting the presence of a stimulus. Progress on the empirical front, however, has not been accompanied by p...

OBJECTIVE White matter hyperintensities (WMH), visualized on T2-weighted MRI, are thought to reflect small-vessel vascular disease. Much like other markers of brain disease, the association between WMH and cognition is imperfect. The concept of reserve may account for this imperfect relationship. The purpose of this study was to test the reserve hypothesis in the association between WMH severit...
