Consciousness: Where We Are At, Imants Barušs

CONSCIOUSNESS: Ideas and Research for the Twenty-First Century

It is useful every couple of years to take a bird’s eye view of consciousness studies and reflect on what we see. When I look, I still see two streams, one of which is the social and political framework for the study of consciousness, and the other of which is the substance of what we know about consciousness. The former is still largely defined by the extent to which the scientific study of consciousness has been freed from a materialist agenda. The latter includes recent research into the clarity of cognitive functioning in the absence of sufficient neurological support for …


Spider Brain Morphology & Behavior, Skye M. Long Jul 2016

Spider Brain Morphology & Behavior, Skye M. Long

Doctoral Dissertations

Spiders are ideal model animals for experimental and comparative studies of behavior, learning and perception. They display many complex behaviors, such as the multimodal mating dances of lycosid spiders, the stealthy hunting strategies of the jumping spider Portia sp., to the labile sociality of theridiids. Spiders also demonstrate a wide range of cognitive capabilities. Spiders perceive their environment using multiple sensory modalities including: chemosensory organs; lyriform and slit-sense organs and specialized hairs that detect vibration and air movement; and up to eight eyes that vary in function, some able to detect polarization and a broad spectrum of light, including …


Premises Of A Natural Science Of Consciousness, Ervin Laszlo Mar 2016

Premises Of A Natural Science Of Consciousness, Ervin Laszlo

CONSCIOUSNESS: Ideas and Research for the Twenty-First Century

According to the mainstream of modern science, there cannot be a natural science of consciousness because consciousness does not actually exist in nature. It is a product or by-product of the workings of the brain. There is a natural science of brain and the nervous system, for these are bona fide elements of the world, but there cannot be a natural science of a phenomenon of which the very existence is in question. In the prevalent view con2sciousness is something that happens when neurons fire in the brain. This is said to be confirmed by experience. There is no consciousness …


Reembodying, Human Consciousness In The Earth, John Briggs Mar 2016

Reembodying, Human Consciousness In The Earth, John Briggs

CONSCIOUSNESS: Ideas and Research for the Twenty-First Century

For the last 20,000 years or so the dominant mode of human consciousness has been one that divides reality into subjects and objects, and focuses on human desires and needs. This anthropocentric mode of consciousness has invented religions, built civilizations, amassed knowledge, and developed technology and science. It has also disembodied us from the Earth and led to the Anthropocene Era. Still with us is another mode of human consciousness that arguably once existed in a balance with the anthropocentric mode during our long hunter-gatherer, Paleolithic sojourn. This holistic, integrative mode of consciousness experiences the Earth as a mother, and …

Criminal convictions require proof that a prohibited act was performed in a statutorily specified mental state. Different legal consequences, including greater punishments, are mandated for those who act in a state of knowledge, compared with a state of recklessness. Existing research, however, suggests people have trouble classifying defendants as knowing, rather than reckless, even when instructed on the relevant legal criteria.

We used a machine-learning technique on brain imaging data to predict, with high accuracy, which mental state our participants were in. This predictive ability depended on both the magnitude of the risks and the amount of information about those …
