Blind Procedures

10.8K
Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...

Decreased Body Temperature

676
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...

Pre-mRNA Processing: Modification of pre-mRNA Ends01:35

Pre-mRNA Processing: Modification of pre-mRNA Ends

9.7K
In eukaryotic cells, transcripts made by RNA polymerase are modified and processed before exiting the nucleus. Unprocessed RNA is called precursor mRNA or pre-mRNA to distinguish it from mature mRNA.
Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a cap to the 5' end of the growing transcript. In this process, a 5' phosphate is replaced by modified guanosine that has a methyl group attached (7-methyl guanosine). This 5' cap helps...

Summary
This summary is machine-generated.

Biological and cognitive agents actively generate their own boundaries, a dynamic process not captured by the Markov blanket in the free-energy principle framework. This highlights a key limitation in understanding agent-environment interactions.

Area of Science:

  • Computational neuroscience
  • Theoretical biology
  • Philosophy of mind

Background:

  • The free-energy principle (FEP) framework models biological and cognitive systems using active inference.
  • Active inference relies on the concept of a Markov blanket to delineate system boundaries.
  • A gap exists between the theoretical Markov blanket and the actual, dynamically generated boundaries of agents.

Purpose of the Study:

  • To address the limitations of the Markov blanket in explaining how agents actively generate their boundaries.
  • To explore the dynamic processes underlying agent-environment boundary formation.
  • To reconcile the theoretical construct of the Markov blanket with observed agent behavior.

Main Methods:

  • Conceptual analysis of the free-energy principle and active inference.
  • Examination of the relationship between Markov blankets and ontological boundaries.
  • Theoretical exploration of boundary-making processes in biological and cognitive systems.

Main Results:

  • The Markov blanket, as presupposed in active inference, does not inherently describe the active generation of boundaries.
  • The dynamic process of boundary formation by agents is not adequately represented by the static concept of a Markov blanket.
  • A disconnect is identified between the theoretical framework and the empirical reality of agent-environment interaction.

Conclusions:

  • The current formulation of active inference within the FEP framework needs refinement to account for active boundary generation.
  • Understanding agent-environment dynamics requires moving beyond the passive demarcation implied by the Markov blanket.
  • Future theoretical developments should focus on the generative processes of boundaries in embodied agents.
