iiinova — where your digital self keeps evolving

The paper discusses in depth the parallels with and potential insights for the bilingual language learning literature. This was a very fun collaborative project together with bilingualism experts @kleind.bsky.social and @kbyers.bsky.social

The development of parallel phonological representations varied based on the timing of language exposure, showing how earlier-learned languages shape the acquisition of subsequent ones.

We show that multiple phonological systems are organized through parallel representations, preserving the unique aspects of each language while maintaining shared articulatory features (here e.g. manner of articulation and consonant voicing).

This was an interesting commentary to write on work by Binder et al. regarding impaired acoustic phonetic perception after unilateral left hemisphere stroke. academic.oup.com/brain/advanc...

This scientific commentary refers to ‘Lesion correlates of impaired acoustic-phonetic perception after unilateral left hemisphere stroke’ by Binder et al.

People talk a lot about objects, but what about the softness of a cushion, the greenness of an emerald, or the viscosity of oil? In our work just published @pnas.org, we shed light on how we make sense of the hundreds of materials around us. www.pnas.org/doi/10.1073/...

20+ years ago, an idea about cortical lateralization of audition was advanced: asymmetric sampling in time (AST). This extensive review/reevaluation by Chantal Oderbolz, me, and Martin Meyer assesses how the idea has fared. #notallwrong www.sciencedirect.com/science/arti...

One week left to apply! We'll have so much exciting data for projects: for example, neuropixel data from humans while they listen to sentences courtesy of @shaileejain.bsky.social, Eddie Chang, and his group.

"Key attributes of successful research institutes" journals.plos.org/plosbiology/... – well-written perspective on what makes research institutes successful. having a lot of resources is not sufficient, if there is no positive research culture or good governance structure.

We demonstrate the approach on a dataset collected using a speaker odd-one-out task, where we show that people’s first language can shape how they perceive continuous and categorical aspects of accents.

Item-level fitting, on the other hand, provides an estimate of the information present in the data that is not accounted for by prior knowledge and remains to be explained. We can use the fitted models for exploration and hypothesis generation.

(Q2) However, we show in simulations how to incorporate design matrices in the model fit. This allows us to quantify how well participants' odd-one-out choices can be explained using prior knowledge (here: stimulus categories).

Both the stimulus feature space and individual rater weights are optimized in a combined procedure using backpropagation. The model can be fitted without taking prior knowledge into account.

100

(Q1) In this task, human raters have to choose the odd-one-out in a triplet of 3 stimuli. In this simulated example two raters disagree on 1 triplet. Our approach assumes a common feature space that describes stimuli, but raters can weigh features differently in their choices.

The approach we propose is based on the odd-one-out task, which was used by @martinhebart.bsky.social to reveal dimensions of object representation.

(Q2) Sometimes the features underlying people’s similarity judgments are not obvious. How can we combine prior knowledge about stimulus domains with data-driven approaches to gain new insights?

In a new preprint with @kleind.bsky.social, we ask two questions: (Q1) People differ in how they perceive the similarity of stimuli in their environment. How can we model the features underlying similarity judgments in arbitrary domains, while accounting for individual differences? osf.io/agpb5_v1 🧵

comparing human & animal brain rhythms: it's easy to find examples where human rhythms are more pronounced than anything you can see in animals, even the famous theta-rhythm. 🙂 as evident by the higher spectral peak. 📉 (this is after adjusting for a difference in absolute signal amplitude)

More work coming soon on how to model features underlying these rater judgments.

This way online participants can rate samples on multiple features, sort them into fixed or flexible number of clusters, or judge their similarity

The nice thing is that audio samples are associated with visual tokens that control audio playback and that can be manipulated depending on the type of rating. You can try it out here: pwdonh.github.io/posts/audio-tokens/
