Can we understand memory as a social and cognitive dynamic in permanent sociodynamic movement?
Memory as a social and cognitive sense of the past in the present reveals that the established paradigm of knowledge of the past interferes in the experience of the present (Connerton, 1989; Le Goff, 1977). The sense or meaning of the past in the present, particularly through the narratives of memory (recollections) expose a dichotomous and constant dynamic between remembering and forgetting. In this sense, can we understand memory as a social and cognitive dynamic in permanent sociodynamic movement?

I would like to invite you to read the recently published article on the theme of the social memory of school from a socio-dynamic perspective. The analysis and reflection was made from testimonies of teachers who taught in schools at the time of the Estado Novo (Portuguese authoritarian regime 1933-1974).

Psychodynamic theories focus on the psychological drives and forces within individuals that explain human behavior and personality. The theories originate from Sigmund Freud's psychoanalysis, which focused on the unconscious mind as the source of psychological distress and dysfunction.
Indeed! Very little in cognitive is not social, and movement (sociodynamic or otherwise) is crucial to the pickup, selection, and retention of information.
Dear Drs. Hasan Abu-Krooz and Damian G Kelty-Stephen,
Thank you very much for your comments.
I think the topic of social memory could be enhanced by further research within the framework of sociodynamics.
Best regards, Rooney Pinto.

A good nonlinear signal analysis methods for short-term signals (from 30 s - 5 min, mainly RR interval series)
Hello everyone!
Through my studies, I used a lot of signal analysis methods for medical data (mostly RR interval series), focusing on the nonlinear ones such as:
- Shannon entropy,
- sample entropy (https://journals.physiology.org/doi/full/10.1152/ajpheart.2000.278.6.H2039?view=long&pmid=10843903),
- approximate entropy ( )
- detrended fluctuation analysis (Peng et al. 1994, ),
- multiscale multifractal analysis ( )
- symbolic analysis ( )
Currently I'm working on RR interval series obtained during listening to (or playing) short excerpts of music pieces. I'm wondering which nonlinear method would be the most appropriate for short-term data, from 30 seconds to 5 minutes (it's about 30-500 samples per signal). My preliminary results showed that I see significant differences between the baseline and the music piece period for Shannon entropy (this parameter works much better than most linear indices). In turn, I cannon see any interesting results using sample entropy and I think that these signals are too short for this method. Similarly, DFA cannot be used for a such short period.
My question is, what other nonlinear methods can I use for short-term analysis and maintaining a good quality level of the results?
I will be grateful for any suggestions.
