“Memory compression” effects in visual working memory are contingent on explicit long-term memory
May 7, 2020
Brady, Konkle, and Alvarez (2009) argued that statistical studying boosts the variety of colours that may be held on-line in visual working memory (WM). They confirmed that when particular colours are constantly paired collectively in a WM job, topics can take optimal benefit of those regularities to recall extra colours, an impact they labeled memory compression.
They proposed that memory compression is a product of visual statistical studying, an computerized apprehension of statistical regularities that has been proven in prior work to be disconnected from explicit studying. If statistical studying allows an enlargement of the variety of individuated representations in visual WM, it will require revision of virtually all fashions of capability in this on-line memory system.
That mentioned, this provocative declare is inconsistent with a number of research which have discovered no enchancment in WM efficiency following quite a few repetitions of particular pattern shows (e.g., Logie, Brockmole, & Vandenbroucke, 2009; Olson & Jiang, 2004). Here, we replicate the Brady et al. (2009) findings however present that memory compression effects had been restricted to topics who had good explicit recall of the colour pairs on the finish of the research, suggesting that statistical regularities boosted efficiency by enabling contributions from long-term memory.
Thus, whereas memory compression effects present an attention-grabbing instance of the tight collaboration between on-line and offline memory representations, they don’t present proof that statistical regularities can increase the variety of individuated representations that may be concurrently saved in visual WM.

Online webinar coaching to analyse advanced atrial fibrillation maps: A randomized trial
Specific instruments have been just lately developed to map atrial fibrillation (AF) and assist information ablation. However, when used in clinical observe, panoramic AF maps generated from multipolar intracardiac electrograms have yielded conflicting outcomes between facilities, seemingly as a consequence of their complexity and steep studying curve, thus limiting the correct evaluation of its clinical affect.
The most important goal of this trial was to evaluate the affect of on-line coaching on the identification of AF driver websites the place ablation terminated persistent AF, by a standardized coaching program. Extending this idea to cellular health was outlined as a secondary goal.
An onlinedatabase of panoramic AF films was generated from a multicenter registry of sufferers in whom focused ablation terminated non-paroxysmal AF, utilizing a freely obtainable technique (Kuklik et al-method A) and a commercial one (RhythmView-method B). Cardiology Fellows naive to AF mapping had been enrolled and randomized to coaching vs no coaching (management). All contributors evaluated an initial set of films to establish websites of AF termination.
Participants randomized to coaching evaluated a second set of films in which they acquired suggestions on their solutions. Both teams re-evaluated the initial set to evaluate the affect of coaching. This idea was then migrated to a smartphone utility (App).12 individuals (median age of 30 years (IQR 28-32), 6 females) learn 480 AF maps. Baseline identification of AF termination websites by ablation was poor (40%±12% vs 42%±11%, P = 0.78), however related for each mapping strategies (P = 0.68).
Training improved accuracy for each strategies A (P = 0.001) and B (p = 0.012); whereas controls confirmed no change in accuracy (P = NS). The Smartphone App accessed AF maps from a number of techniques on the cloud to recreate this coaching atmosphere.Digitalonline coaching improved interpretation of panoramic AF maps in beforehand inexperienced clinicians.
Combining on-line clinical knowledge, smartphone apps and different digital sources supplies a robust, scalready strategy for coaching in novel methods in electrophysiology.
