The IDEA (Internal Dominance over External Attention )
Sam Verschooren and Tobias Egner published “ When the mind’s eye prevails: “The Internal Dominance over ExternalAttention (IDEA) hypothesis“. The IDEA hypothesis asserts, contrary to the traditional view of attention as being primarily externally oriented, that attention is inherently biased toward internal information. Mine inner sense predominates in such a way over my five senses…

The self is an illusion
The truth is that your left brain has been interpreting reality for you your whole life, and if you are like most people, you have never understood the full implications of this. This is because we mistake the story of who we think we are for who we truly are. “Why are you unhappy?Because 99.9 percent of…

Decoding reward–curiosity conflict in decision-making from irrational behaviors
Humans and animals are not always rational. “Decoding reward–curiosity conflict in decision-making from irrational behaviors” discusses the fact humans not only rationally exploit rewards but also explore an environment owing to their curiosity. However, the mechanism of such curiosity-driven irrational behavior is largely unknown. The article develops a decision-making model for a two choice task…

Creativity in Motion
Some publications related to this topic: Embodiment and Human Development It is becoming increasingly accepted that the study of cognitive, social, and emotional processes must account for the embodiment of these processes in living, acting people. Within cognitive science, how bodily factors play a role in mental life is often considered through the lens of…

Legs move, thoughts flow : Physical exercise influences creative thinking
I only give a summary of the article, lacking the capability to understand and read the native language. Still, the summary is very interesting: Creative thinking is the ability to generate novel and useful solutions to a problem, of which divergent and convergent thinking are two common types. Evidence shows that physical exercise may influence…

Social and Affective Neuroscience of Everyday Human Interaction
I found – rather serendipitous – this recent, open access and very interesting book “Social and Affective Neuroscience of Everyday Human Interaction“, edited by Springer 2023. This Open Access book presents the current state of the art knowledge on social and affective neuroscience based on empirical findings. This book is open access, which means that…

Avoid the Hijack – Be Emotionally Intelligent
An 80-Year Harvard Study Shows Emotionally Intelligent People Use the Wiser Model to Handle Strong Emotions Don’t let your emotions hijack your actions.Slow down and choose better with the Wiser model. What follows is based on the original text of an Inc.com article by Jessica Stillman, dated May 4, 2023.The opinions expressed here by Inc.com columnists are…

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…

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…

How Occam’s razor guides human decision-making
A rather complex but very interesting article was published @PennLibraries and (somewhat more recent) @bioRXiv But for those who want to understand by a lecture, I can recommend the Simons Faoundation lecture from Joshua Gold (also available on Youtube: How Occam’s Razor Guides Human and Machine Decision-Making) Occam’s razor is the principle stating that, all…

Brain-Behavior relationships
“Improving the study of brain-behavior relationships by revisiting basic assumptions” discusses how scientific communities tacitly agree on assumptions about what exists (called ontological commitments), what questions to ask, and what methods to use. All assumptions are firmly rooted in a philosophy of science that need not be acknowledged or discussed but is practiced nonetheless. In…

“Average is good, extremes are bad”
Traditionally, studies emphasize differences in neural measures between pathological and healthy groups, assuming a binary distinction between the groups, and a linear relationship between neural measures and symptoms. A continuous relation across the divide of normal and pathological states between neural measures and mental functions shows a relation which can be characterized by a nonlinear…

Intellectual humility
Intellectual humility involves recognizing that there are gaps in one’s knowledge and that one’s current beliefs might be incorrect. For instance, someone might think that it is raining, but acknowledge that they have not looked outside to check and that the sun might be shining. Research on intellectual humility offers an intriguing avenue to safeguard…

Language influences perception and concept formation
A neurobiologically constrained model of semantic learning in the human brain was used to simulate the acquisition of concrete and abstract concepts, either with or without verbal labels. Concept acquisition and semantic learning were simulated using Hebbian learning mechanisms. The network’s category learning performance is defined as the extent to which it successfully: (i) grouped…
