Our findings demonstrate the critical role that cognitive dynamics play in explaining the mechanisms through which cognitive inflexibility arises in older adulthood.
shenhavlab.bsky.social
With increasing age, people move slower through the space of control configurations that determine performance. We also show that the ability to adjust control configurations and the ability to maintain performance despite goal switches is maintained across the lifespan.
shenhavlab.bsky.social
Using computational modeling and building on our previous work (psycnet.apa.org/record/2026-...), we measured changes in two control signals (attentional focus and response caution) as people of different ages switched between goals that induced distinct control configurations.

We propose that the speed of movement between control limits cognitive flexibility in older adults. To test this, we had people across the lifespan perform a cognitively demanding task with changing performance goals (perform the task quickly vs. accurately).
shenhavlab.bsky.social
Changing goals require adjustments of cognitive control configurations (e.g., level of attentional focus), even within similar tasks (e.g., emailing a friend vs. your boss). We formalize such adjustments as a dynamical system moving from its current state to the new target state.

New preprint led by Ivan Grahek!

Shifting demands of daily life require constant adjustments in how we allocate cognitive resources. Here we show that slower transitions between different cognitive strategies limit cognitive flexibility across the lifespan: biorxiv.org/content/10.1...

Slower transitions between control states lead to reductions in cognitive flexibility over the lifespan
Declines in cognitive flexibility are a hallmark of cognitive aging, but their causes remain elusive. Here, we examine a previously untested source of aging-related cognitive inflexibility, building o...

In a TEDx talk just out, @ashenhav.bsky.social discusses what research from our lab teaches us about “How to choose when choosing is hardest” (the talk’s original title 😆):

Overall, we show that changing control states (attention and caution) to meet a new goal induces control adjustment costs, and that these costs arise from cognitive control dynamics. Good luck with your post-Twitter-scroll goals!
shenhavlab.bsky.social
We also show (Study 4) that the frequency of performance goal changes parametrically increases the costs, and that the expectation about change frequency determines the cost.
shenhavlab.bsky.social
We also confirmed 2 other predictions our model makes: we show that people exhibit larger costs when target control states are more distant (Study 2) and when they have less time to adjust control (Study 3).
shenhavlab.bsky.social
Confirming the prediction of the model, in Study 1 we found that control states (defined by levels of threshold and drift rate) are pulled closer together in blocks which demand control adjustments that produce costs.
shenhavlab.bsky.social
Due to the time it takes to adjust control states, the model predicts the existence of a control adjustment cost. When frequently moving between different goals (Varying blocks) people will undershoot their target control state.
shenhavlab.bsky.social
We develop a dynamical systems model to describe such adjustments in continuous control signals. Our model proposes that control states are adjusted gradually from their current state toward the target state specified by the new performance goal.
shenhavlab.bsky.social
Different performance goals require different cognitive control states. Performing a task quickly can be done with low levels of caution (Threshold) and attention (Drift rate), but being accurate (Accuracy goal) requires an increase in caution and attention.

After scrolling Twitter, it will take you a while to get back into “work mode”. Why is this the case? Our new work (out now in Psych Review), led by Ivan Grahek and Xiamin Leng, explores the costs of adjusting cognitive control to meet different goals:

Why do measures of putatively the same construct so often fail to correlate strongly across units of analysis (self/informant report, behavioral, physiological/neural): measurement problems or truly actually capturing different constructs (or some of both)?
