Bu kitabı birlikte yazdığımız tüm yazarlara teşekkür ederim.
Keyifli ve bilgilendirici bir süreçti; umarım okurlar için de öyle olur.
Merak edip okursanız çok mutlu oluruz. Görüşlerinizi ve tartışmaya açmak istediğiniz soruları duymak isteriz.
Her bölüm, zihnin orkestrasını farklı bir açıdan inceliyor:
• @bernaguler.bsky.social, Busenur Akbaş ve ben — yürütücü işlevlerin kuramları
• Pınar Uğurlar — öz düzenleme
• Efe Soyman — duygu kontrolü
• Burcu Ünlütabak — çocuklarda merak
• Demet Özer & Ece Yılmaz — jestler & anlama
Bu soruların ortak bir cevabı var: yürütücü işlevler.
Yeni kitabımız Zihnin Orkestra Şefi, kararlarımızı, duygularımızı ve merakımızı yöneten bu sistemi, alanında uzman araştırmacılarla ele alıyor.

Bazen neden duygularımızı kontrol edemiyoruz?
Neden bazı çocuklar durmadan soru sorar?
Aynı anda hem plan yapıp hem esnek kalmak neden bu kadar zor?
Jestlerimiz gerçekten düşünme biçimimizi etkiler mi?
Duygularımızı, düşüncelerimizi, tepkilerimizi nasıl yönetiriz? 🧠👇
Finally, a huge shout-out to Ahmet Burhan Bağlar (@bağlar), who led this project with incredible care—
teaching himself mixed-effects modeling, working meticulously, and writing a truly beautiful paper. 👏
Couldn’t be prouder of this work. 😊
In short:
The mind segments experience based on what it knows, what it expects, and whether context remains stable.
Event cognition is adaptive and deeply knowledge-dependent.
Instead, the findings highlight the role of contextual transitions, consistent with our recent work showing that contextual stability is a dominant driver of segmentation (Güler, Serin, & Günseli et al., 2025): link.springer.com/article/10.3...
Context shifts (e.g., color transitions) reliably triggered segmentation even when fully predicted.
This challenges accounts where prediction error alone drives event boundaries.
Segmentation patterns also changed over time, likely reflecting how participants updated their expectations as they gained experience.
Prediction clearly matters—but that’s still not the whole story.
When experience matched prior knowledge → coarser segmentation
When experience violated knowledge → finer segmentation
➡️ Knowledge is a double-edged sword for event segmentation.
We trained participants on specific image sequences, then asked them to mark event boundaries in real time.
Crucially, sometimes the world matched their knowledge—and sometimes it violated it.
An untrained control group allowed us to isolate the role of prior knowledge.
Event segmentation is how the mind divides continuous experience into meaningful chunks.
Existing work shows that knowledge yields coarser segmentation (experts see fewer boundaries).
We show this is only half the story.
How does prior knowledge affect the way we experience the world?
In our new paper, we show that prior knowledge can both increase and decrease how often experience is segmented into events.

Led superbly by Berna Güler (@bernaguler.bsky.social), who shaped and drove this project, building on initial work by Sümeyye Karahamza, in collaboration with Yağmur Şentürk, @odedbein.bsky.social, & @davidclewett.bsky.social.
We find strong evidence for boundary-triggered reactivation of preceding event information, but mixed evidence for within-event accumulation—suggesting WM contributes to segmentation primarily at event boundaries.
New preprint on how working memory (WM) supports event segmentation. Using load-sensitive EEG markers, we test whether WM accumulates information within events or instead reactivates prior event information at boundaries. osf.io/preprints/ps...
Illustration of the hypothesized flows of information between perception, memory and cognitive control in a conceptual model of working memory. Stimuli attributes are processed to varying degrees of abstraction and parts of these representations can be loaded into working memory under the guidance of cognitive control. Familiar stimuli such as the letter B activate visually abstract representations while less familiar stimuli are limited to sensory representations. Information can be shifted both up and down levels of the perceptual hierarchy to build either more or less abstract representations of either perceived or imagined stimuli. Working memories can be shifted into or out of the hierarchy as needed.
We recently published a theoretical review about how compositional and generative mechanisms in working memory provide a flexible engine for creative perception and imagery.

Is WM a gateway to LTM? In this registered report we find that higher WM load rarely impairs LTM encoding - suggesting WM capacity is not a bottleneck for forming LTM traces. @as-souza.bsky.social @edamizrak.bsky.social @cognition-zurich.bsky.social psycnet.apa.org/record/2026-... [1/3]
New paper out on value-based prioritization in visual WM. We used hDDM to account for speed/accuracy tradeoffs and isolate memory benefits from perceptual/motor benefits. We see perceptual/motor contributions suggesting that prioritization benefits are not purely mnemonic.

Huge shoutout to Nursima Ünver for leading this project with incredible dedication, all while continuing her PhD abroad. Grateful for her hard work, persistence, and scientific curiosity. 😊
Our new preprint is out!
Using a continuous-report paradigm, we show that divided attention reliably disrupts long-term memory retrieval by reducing accessibility—not precision.
Two experiments + mixture modeling + TCC.

Huge kudos to @bernaguler.bsky.social for spearheading this project from design to writing, and to Fatih Serin for his critical contributions throughout. It was a privilege to collaborate with such brilliant and dedicated colleagues.
We'd love to hear your thoughts!
These results challenge the long-standing view that prediction errors are the key triggers of event segmentation. Instead, they suggest that stable contextual structure is what shapes episodic memory.
In Experiment 4, we manipulated predictability: some context transitions were preceded by a counter, making them fully expected. Segmentation was equally strong, whether transitions were predictable or not.
In Experiments 1–3, transitions across stable contexts (e.g., task rule, object category) produced stronger segmentation than prediction errors without stable context. Prediction error alone wasn’t enough.
We directly compared these two views across four experiments by independently manipulating contextual stability and prediction error—something past studies often confounded.
Event segmentation—the process of turning continuous experience into discrete memory episodes—is thought to be triggered by prediction errors. But an alternative account suggests it’s transitions between stable contexts that matter more.
We just published a new paper in Psychonomic Bulletin & Review examining what drives how people segment continuous experience into distinct memory events.
The takeaway: contextual stability, not prediction error, is the main driver.🧵https://doi.org/10.3758/s13423-025-02723-4
New Preprint with @edamizrak.bsky.social! Performance in immediate memory tasks reflects a flexible mixture of contributions of #workingmemory and LTM. Distraction disrupts WM, while PI impairs retrieval from LTM; when both are in play, performance depends on the relative reliability of each system
