Happy to update: our Autism Research paper published today: "Poor synchronization yet adequate tempo-keeping in adults with autism", Kasten, Jacoby &  Ahissar: ASDs' poor synchronization to external beat stems from reduced online error-correction and not higher internal noise .

We call the task specific, training-induced switch, which allows bypassing capacity limitations of working memory - perceptualization:.

Abstract. In contrast to perceptual tasks, which enable concurrent processing of many stimuli, working memory (WM) tasks have a very small capacity, limiti

Here is our (T Malinovitch, P Albouy, R Zatorre and me) reply in the coming paper in Cerebral Cortex:.Training allows switching from limited-capacity manipulations to large-capacity perceptual processing.

Can Working memory training have a general impact on our cognitive capacity? .With adaptive training - most people substantially improve in tasks which seem to require online manipulations that exceed human abilities. What's happening?.

Happy to update on our upcoming paper (Gertsovski & Ahissar, J Neurosci. 2022) - showing that auditory cortex of people with dyslexia is insensitive to simple sound regularities. It suggests a perceptual basis for reduced learning of repeated stimuli pattern in dyslexia.

"Slow-update" in autism - previously shown to be an impediment to forming perceptual predictions, now to sensorimotor synchronization - our new paper in Nature Communication - 😀.

First paper alert 🎉 with @norijacoby (@CompAudition) and @MeravAhissar - using computational modelling of tapping, we show synchronization difficulties in autism are explained by slow updating of internal representations:.1/7

Coronavirus epidemiology - how come we know so little? There are thousands of carriers. How come we do not understand the patterns of infections with all the data the carriers have about their whereabouts? How come there is no cross information between the medical and gps stats ?.

Most learning is implicit, learning regularities of the world. But the world is volatile. How sensitive are we to changes in the environment? how do individuals differ in this sensitivity? If interested please vote for our symposium on volatility at #CNS2020 in Boston😀.

Got ERC advanced to study our hypothesis :. Updating priors quickly, crucial for sensorimotor synchronization and social interactions, is impaired in autism . Accumulating detailed stat (e.g. that of a language) crucial for fast reading, is impaired in dyslexia.

😀 our new JEP G paper :. Auditory frequency discrimination is correlated with linguistic skills, but its training does not improve them or other pitch discrimination tasks. dissociates correlation from causality in perceptual learning of pitch.

Last days to submit an abstract to the meeting on Statistical Learning - hopefully it will be appealing to a broad community using different paradigms and contexts from currently separate disciplines.
