A visual history of human knowledge

I am a HUGE fan of data visualization and network theory and analytics. I think these techniques, when applied to intelligence test data, could provide us much more important insights than the continued use (misuse?) of linear SEM/CFA models. Network visual models are elegant...and more reflective of "reality".

This is a very good TED talk.

I have made a number of posts that suggest that certain forms of brain training technology, particularly those that focus on quieting the default brain network (e.g., Interactive Metronome. https://www.interactivemetronome.com), appear to be doing something similar to certain forms of focused attention meditation.  See this one post in particular.  http://www.brainclock.net/2015/07/brain-networks-and-fine-tunning.html

Temporal cognition: Connecting subjective time to perception, attention, and memory. [feedly]



----
Temporal cognition: Connecting subjective time to perception, attention, and memory.
// Psychological Bulletin - Vol 136, Iss 4

Time is a universal psychological dimension, but time perception has often been studied and discussed in relative isolation. Increasingly, researchers are searching for unifying principles and integrated models that link time perception to other domains. In this review, we survey the links between temporal cognition and other psychological processes. Specifically, we describe how subjective duration is affected by nontemporal stimulus properties (perception), the allocation of processing resources (attention), and past experience with the stimulus (memory). We show that many of these connections instantiate a "processing principle," according to which perceived time is positively related to perceptual vividity and the ease of extracting information from the stimulus. This empirical generalization generates testable predictions and provides a starting-point for integrated theoretical frameworks. By outlining some of the links between temporal cognition and other domains, and by providing a unifying principle for understanding these effects, we hope to encourage time-perception researchers to situate their work within broader theoretical frameworks, and that researchers from other fields will be inspired to apply their insights, techniques, and theorizing to improve our understanding of the representation and judgment of time.

Brain timing shares significant genetic component with intelligence

Interesting behavioral genetics study that demonstrates that millisecond temporal processing in the brain has a significant genetic component that is also shared with general intelligence. This (and other) research continues to indicate the importance of investigating "brain timing" as an important component of cognitive functioning. Also, this research indicates that this association is not all genetic--which suggests that interventions that might produce changes in basic neural timing mechanisms may increase cognitive efficiency/functioning.
