What to Choose Next? A Paradigm for Testing Human Sequential Decision Making

Michael Herzog, Elisa Tartaglia, Aaron Michael Clarke

Many of the decisions we make in our everyday lives are sequential and entail sparse rewards. While sequential decision-making has been extensively investigated in theory (e.g., by reinforcement learning models) there is no systematic experimental paradigm ...

Human and Machine Learning in Non-Markovian Decision Making

Walter Senn, Michael Herzog, Elisa Tartaglia, Silvia Marchesotti, Aaron Michael Clarke

Humans can learn under a wide variety of feedback conditions. Reinforcement learning (RL), where a series of rewarded decisions must be made, is a particularly important type of learning. Computational and behavioral studies of RL have focused mainly on Ma ...

Linking perceptual learning with identical stimuli to imagery perceptual learning

Michael Herzog, Fred Mast, Elisa Tartaglia, Lukasz Grzeczkowski

Perceptual learning is usually thought to be exclusively driven by the stimuli presented during training (and the underlying synaptic learning rules). In some way, we are slaves of our visual experiences. However, learning can occur even when no stimuli ar ...

Perceptual Learning With Only One Stimulus

Michael Herzog, Fred Mast, Elisa Tartaglia, Lukasz Grzeczkowski

Perceptual learning is learning to see. For example in a bisection task, three parallel lines are presented with the central line slightly offset towards the right or the left outer line. Participants indicate the offset direction. Training gradually impro ...

Perceptual learning of motion discrimination by mental imagery

Michael Herzog, Fred Mast, Elisa Tartaglia, Laura Bamert

Perceptual learning can occur when stimuli are only imagined, i.e., without proper stimulus presentation. For example, perceptual learning improved bisection discrimination when only the two outer lines of the bisection stimulus were presented and the cent ...

Perceptual learning: why mice do not play backgammon

Elisa Tartaglia

Perceptual learning is the ability to modify perception through practice. As a form of brain plasticity, perceptual learning has been studied for more than thirty years in different fields including psychology, neurophysiology and computational neuroscienc ...

Modeling perceptual learning: why mice do not play backgammon

Michael Herzog, Elisa Tartaglia, Carl Kristoffer Aberg

Perceptual learning is often considered one of the simplest and basic forms of learning in general. Accordingly, it is usually modeled with simple and basic neural networks which show good results in grasping the empirical data. Simple meets simple. Comple ...

Anesthesia prevents auditory perceptual learning

Alain Farron, Michael Herzog, Elisa Tartaglia, Carl Kristoffer Aberg

BACKGROUND: An auditory perceptual learning paradigm was used to investigate whether implicit memories are formed during general anesthesia. METHODS: Eighty-seven patients who had an American Society of Anesthesiologists physical status of I-III and were s ...

Human perceptual learning by mental imagery

Michael Herzog, Fred Mast, Elisa Tartaglia, Laura Bamert

Perceptual learning is learning to perceive. For example, a radiologist is able to easily identify anomalies in medical images only after extended training. Theoretical and psychophysical studies [1-12] suggest that such improvements of performance are acc ...

Perceptual learning with Chevrons requires a minimal number of trials, transfers to untrained directions, but does not require sleep

Michael Herzog, Elisa Tartaglia, Carl Kristoffer Aberg

In most models of perceptual learning, the amount of improvement of performance does not depend on the regime of stimulus presentations, but only on the sheer number of trials. Here, we kept the number of stimulus presentations constant while varying the n ...

Perceptual learning and roving: Stimulus types and overlapping neural populations

Michael Herzog, Elisa Tartaglia, Carl Kristoffer Aberg

In perceptual learning, performance usually improves when observers train with one type of stimulus, for example, a bisection stimulus. Roving denotes the situation when, instead of one, two or more types of stimuli are presented randomly interleaved, for ...

Perceptual learning by mental imagery

Michael Herzog, Fred Mast, Elisa Tartaglia, Laura Bamert

In a bisection discrimination task, two vertical outer lines delineate an interval which is bisected by a centre line. Observers indicate whether this centre line is closer to the left or right outer line. Performance in this task improves strongly with tr ...

Roving in perceptual learning: stimulus interference and overlapping neural populations

Michael Herzog, Elisa Tartaglia, Carl Kristoffer Aberg

Performance usually improves when observers train with one type of a visual stimulus. Roving denotes the situation when, instead of one, two or more types of stimuli are presented randomly interleaved (one per trial). For some stimulus types, performance i ...

When does roving disrupt perceptual learning?

Michael Herzog, Elisa Tartaglia, Carl Kristoffer Aberg

Training with one type of a visual stimulus usually improves performance. When observers train with two or more stimulus types presented in random order (so-called roving), performance improves for certain stimulus types but not for others. To understand w ...

Perceptual learning by mental imagery

Michael Herzog, Fred Mast, Elisa Tartaglia, Laura Bamert

In perceptual learning, performance improves when stimuli are presented over and over again. In a bisection task, for example, two vertical outer lines delineate an interval which is bisected by a centre line. Observers indicate whether this centre line is ...

Perceptual learning requires a minimal number of trials per session, but no sleep

Michael Herzog, Elisa Tartaglia, Carl Kristoffer Aberg

A common assumption in perceptual learning is that the improvement of performance basically depends on the amount of training. However, other factors such as sleep and training intensity (trials per session) have also been shown to be important. We trained ...
