SummaryThe fields relevant to this overview are a part of the interdisciplinary studies of cognitive science, which includes anthropology, cognitive psychology, developmental psychology, psycholinguistics, artificial intelligence and computational science, and neuroscience. Each of these disciplines provides an important and unique perspective on how to understand the human psyche. Biological, psychodynamic, and social psychiatry can find a common home and language within cognitive science. The common divisions of nature versus nurture and biology versus psychology disappear when the origins of mental processes are examined.
Table of Contents
- The last ten years of the twentieth century, called the 'Decade of the Brain,' led to discoveries in the neurosciences that revealed a wide range of findings relevant to psychiatry.
- A generally accepted view of the mind is that it emanates from a portion of the activity of the brain.
- The neural net profile is the fundamental way in which mental processes are created.
- Information is contained within the brain by a process of representation.
- A third level of viewing information processing in the mind (C) is the conceptualization of forms of sensation, perception, attention, and memory.
- Early conceptualizations of attention were based on Donald Broadbent's idea of a filter that selects a limited amount of incoming stimuli to be further processed.
- Selective Attention One aspect of attention is that it focuses a metaphorical spotlight on external stimuli or internal mental representations.
- Optimal performance is attained with moderate levels of arousal that allow for the establishment of task goals and feedback from the performance of the task, leading to appropriate resource allocation.
- Forms of representations include sensory and perceptual ones that derive from input from the external world via the peripheral sensory nervous system.
- The neural networks of the brain are capable of responding to experience by the activation of particular patterns of distributed activation.
