Our objective was to obtain preliminary evidence for an order of emergence of measurable reductions in cognitive-linguistic abilities and processing/naming speed. A total of 22 patients with mild-to-moderate Alzheimer's disease (AD) or mild cognitive impairment and 22 age- and sex-matched controls participated. Ross Information Processing Test-Geriatric (RIPA-G) evaluated functional information...

We conducted an experiment, similar to those in (Peterka 2002) but augmented to include information processing (IP) tasks, to explore this question. Data were fit to a postural control model (Peterka 2002; Peterka and Loughlin 2004). We explicitly added “attention” to the model and its influence on sensory integration via the sensory weight and time delay parameters of the model (Fig. 1). This ...

Alcoholism is associated with impairment of information processing attention, memory and concept formation, which hamper the patients response to psychotherapy aimed at treating alcoholism. We improved cognitive functioning in abstinent alcoholics through cognitive retraining. Eight detoxified male alcoholics, comparable on age, education, marital status, medication and years of alcohol consump...

A review was conducted of studies that assessed the effects of acute bouts of physical activity on adults' cognitive performance. Three groups of studies were constituted on the basis of the type of exercise protocol employed. Each group was then evaluated in terms of information-processing theory. It was concluded that submaximal aerobic exercise performed for periods up to 60 min facilitate s...

Introduction: The majority of the daily life activities involve the concurrent performance of simultaneously challenging motor and cognitive activities, such as talking while walking, which requires the vestibular system for balance. Functional balance allows the brain to interpret and integrate the sensory information from our physical and social environment. This study aimed to investig...

BACKGROUND Limited information processing capacity in the brain necessitates task prioritisation and subsequent adaptive behavioural strategies for the dual-task coordination of locomotion with severe concurrent cognitive loading. Commonly observed strategies include prioritisation of gait at the cost of reduced performance in the cognitive task. Alternatively alterations of gait parameters suc...

If the brain is a machine that processes information, then its cognitive activity can be interpreted as a set of information processing states linking stimulus to response (i.e. as a mechanism or an algorithm). The cornerstone of this research agenda is the existence of a method to translate the measurable states of brain activity into the information processing states of a cognitive theory. He...

This paper proposes a brain-inspired cognitive architecture that incorporates approximations to the concepts of consciousness, emotion, and imagination. To emulate the empirically established cognitive efficacy of conscious as opposed to unconscious information processing in the mammalian brain, the architecture adopts a model of information flow from global workspace theory. Cognitive function...
