Explaining mathematically why most people chose 7 when asked to chose a number between 1-10

Last day, I watched a video at ‘Numberphile’ which made a strange demand. According to the video, if you ask people to randomly pick any one integer between 1 and 10 (both inclusive), people are more likely to choose 7. They also said that around…

What is "Predictive Reverse Engineering" and how can it be used for understanding brain structure?

Here is a quotation from the paper Markram et al., Introducing the Human Brain Project : New informatics and modeling approaches are making it possible to reverse engineer the detailed structure of the human brain without resort to invasive…

How are the outputs of neurons encoded, if at all?

The way I learned it, a neuron fires with a fixed amplitude, and the only information encoded in the output is the frequency at which it fires. 10 spikes per second is in some sense a 'stronger' signal than 5 spikes per second. But from a…

Are ACT-R and Spaun the state of the art in cognitive science computational models?

I've been looking for a computational model in cognitive science, and perused Anderson's "How can the human mind occur in the physical universe?". I've also seen this question comparing ACT-R with a empirical model called Spaun. Are Anderson's ACT-R…

What is fiber bundle matching?

In the introduction of this paper, the authors mention something called "fiber bundle matching". I'm having trouble understanding if this is an analysis performed on a single subject's data or across subjects. In other words, do you match fibers…

Is HTM (Hierarchical Temporarl Model) accepted as credible?

I ran across this article Why Neurons Have Thousands of Synapses, a Theory of Sequence Memory in Neocortex, which leads to Wikipedia and HTM. To my reading, this provides a credible theory of sensory encoding and neocortical processing, along with a…

What models are there for neuronal sequence memory?

This paper https://www.frontiersin.org/articles/10.3389/fncir.2016.00023/full proposes a neuronal model to learn time-based sequences, referred to as HTM (https://en.wikipedia.org/wiki/Hierarchical_temporal_memory). An implementation is here:…

Confusion about Marr's "computational level" and computational neuroscience

I'm writing my masters thesis in the field of computational neuroscience (using a spiking model). One of my supervisors is a cognitive scientist, who likes to use Marr's 3 levels of analysis. Marr's 'computational level' is the highest of the three,…

Success rate of computational models in psychology

I come from computer science background. I don't know anything about formal studies of psychology. I intend to know about the success rate of computational models in domain of psychology. Is it possible to implement these models to classify learners…
