Over the next decade the DoD will be challenged to deploy cognitive information processing systems that will embody learning and reasoning using semantically rich knowledge representations in applications such as autonomous vehicles, intelligence analysts, and electronic surveillance. In addition to the significant computational demands, cognitive applications must deal with uncertainty and ine...

A theory is described which links cognitive changes observed in normal aging to an underlying decline in the function of the dopamine (DA) system projection to prefrontal cortex (PFC). The theory postulates that this neural mechanism is integral to the representation, maintenance and updating of context information, and as such impacts cognitive control across a wide range of cognitive domains,...

articles on information processing theory and learning disabilities. Two diverse articles are provided, both extremely important to our discussion on learning disabilities. The first article focuses on neuropsychological aspects of learning disabilities, while the other focuses on microcomputer technology. The inclusion of the first article by His-cock and Kinsbourne appears to be "out of conte...

Introduction and abstract ˆ This short paper is offered as a foil to those produced by real thinkers about emotions.1 It is also a chance for me to think about something new, for I haven't studied emotions before, although I have spent considerable time thinking about cognitive architectures. We will find that emotions will be and must be incorporated into architectures for cognition, that both...

Cognitive load theory is widely accepted by instructional designers, since it provides a theoretical foundation of designing guidelines for constructing learning material in a way that enhances learning. According to this theory, learning will be impaired if the learning material causes a cognitive overload. Since the capacity of working memory is very limited, the theory assumes that presentin...

cognitive deficits such as impairments in attention, memory, information processing and executive functioning can be found in some parkinson's disease (pd) patients. recent studies suggested that pd drivers generally performed poorer than their healthy age-matched controls with regards to their cognitive and motor abilities during the psychometric testing. according to michon’s model of ca...

The cognitive concept of representation plays a key role in theories of brain information processing. However, linking neuronal activity to representational content and cognitive theory remains challenging. Recent studies have characterized the representational geometry of neural population codes by means of representational distance matrices, enabling researchers to compare representations acr...

John Bowlby formulated the core of Attachment Theory whilst working in a multidisciplinary team of childcare professionals, psychoanalysts, ethologists and other researchers at the Tavistock Clinic for over thirty years after the Second World War (Holmes 1993). From its inception Attachment Theory integrated concepts from academic fields as diverse as Ethology, Cognitive Science and Psychoanaly...

This research uses fMRI to understand the role of eight cortical regions in a relatively complex information-processing task. Modality of input (visual versus auditory) and modality of output (manual versus vocal) are manipulated. Two perceptual regions (auditory cortex and fusiform gyrus) only reflected perceptual encoding. Two motor regions were involved in information rehearsal as well as pr...
