Consciousness begins with feeling, not thinking
A new theory of embodied consciousness has been described by Antonio Damasio and Hanna Damasio in Consciousness begins with feeling, not thinking. Forget ‘I think therefore I am’. feelings are the source of consciousness. Long dismissed as secondary to reason, feelings are where consciousness begins. Without them, consciousness is impossible – with radical implications for the ‘hard…

States of Mind (SoMs): TD:BU balance
Noa Herz, Shira Baror, and Moshe Bar discuss in a 2020 opinion article the Overarching States of Mind.We all have our varying mental emphases, inclinations, and biases. These individual dispositions are dynamic in that they can change over time and context. The opinion article proposes that these changing states of mind (SoMs) are holistic in…

The innovation and intelligence of goats …
Goats have not (yet) earned a reputation for their problem-solving abilities. But if you hide food in a strange cup and put a lid on it, a goat may find a way, a new study finds. And not just any goat. Animals that functioned like outsiders in their social group were best at tackling and…

Perceived time & heartbeat
This blog entry about the Current Biology article “Perceived time expands and contracts within each heartbeat” relates perfectly to my previous blog on “cardiac activity: its role in perception and action“ Perception of passing time can be distorted. Emotional experiences, particularly arousal, can contract or expand experienced duration via their interactions with attentional and sensory…

Cardiac activity: its role in perception and action
Patterns of cardiac activity continuously vary with environmentaldemands, accelerating or decelerating depending on circumstances. Simultaneously, cardiac cycle affects a host of higher-order processes, where systolic baroreceptor activation largely impairs processing. However, a unified functional perspective on the role of cardiac signal in perception and action has been lacking. — Patterns of cardiac activity continuously vary…

Human innovation depends on our collective brains
A recent study investigates hunters’ causal understandings of bow design and mechanics among the Hadza, one of the last remaining foraging populations. The results suggest that sophisticated technology can evolve without complete causal understanding. Human innovation depends not on our individual brainpower but on our collective brains, on networks of diverse minds sharing information, lucky…
