Automatic Processing and Automatic Social Behavior01:28

Automatic Processing and Automatic Social Behavior

86
Automatic processing refers to the cognitive operations that occur without conscious intent or awareness, playing a fundamental role in shaping social cognition and behavior. These processes enable individuals to navigate complex social environments efficiently by relying on mental shortcuts and pre-existing knowledge structures known as schemas. One of the most influential mechanisms underlying automatic processing is priming, which subtly activates mental representations through exposure to...

Non-equilibrium in the Cell

5.0K
An important concept in studying metabolism and energy is that of chemical equilibrium. Most chemical reactions are reversible. They can proceed in both directions, releasing energy into their environment in one direction, and absorbing it from the environment in the other direction. The same is true for the chemical reactions involved in cell metabolism, such as the breaking down and building up of proteins into and from individual amino acids, respectively. Reactants within a closed system...

Improving Translational Accuracy

12.1K
Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

Area of Science:

  • Neurology
  • Medical Imaging
  • Artificial Intelligence

Background:

  • Accurate Alberta Stroke Program Early CT Score (ASPECTS) assessment is crucial for large vessel occlusion (LVO) stroke management.
  • Early CT interpretation can be challenging, especially for non-neuroradiologists.

Purpose of the Study:

  • To evaluate the impact of a machine learning (ML)-based software tool on physicians' ability to interpret ASPECTS.
  • To compare unassisted ASPECTS scoring with ML-assisted scoring in LVO stroke patients.

Main Methods:

  • 50 CT scans from prior studies were assessed by 3 expert neuroradiologists to establish a reference standard.
  • Non-neuroradiologist readers and neuroradiologists scored scans with and without ML software assistance.
  • Agreement was measured by the percentage of ASPECTS regions correctly identified.

Main Results:

  • Unassisted typical readers achieved 72% agreement with the expert consensus.
  • The ML software alone achieved 77% agreement.
  • ML-assisted reading improved agreement to 78%, a statistically significant enhancement (P<0.0001).

Conclusions:

  • Machine learning software significantly improves ASPECTS scoring accuracy for typical readers.
  • ML-assisted interpretation allows non-expert readers to achieve agreement rates comparable to neuroradiologists.
