Working memory is integral to a range of critical cognitive functions such as reasoning and
decision‐making. Although alterations in working memory have been observed in …

The pupil of the eye provides a rich source of information for cognitive scientists, as it can
index a variety of bodily states (eg, arousal, fatigue) and cognitive processes (eg, attention …

Moment-to-moment fluctuations in arousal can have large effects on learning and memory.
For example, when neutral items are predictive of a later reward, they are often remembered …

A rapid detection and processing of relevant information in our environment is crucial for
survival. The human eyes are drawn to social or threatening stimuli as they may carry …

The brain's arousal state is controlled by several neuromodulatory nuclei known to
substantially influence cognition and mental well-being. Here we investigate whether human …

Inconclusive evidence suggests that the pupil is more dilated when the breadth of attention
is broad compared to narrow. To further investigate this relationship, we recorded pupil size …

In everyday perception, we combine incoming sensory information with prior expectations.
Expectations can be induced by cues that indicate the probability of following sensory …

The assessment of mental effort is increasingly relevant in neurocognitive and life span
domains. Pupillometry, the measure of the pupil size, is often used to assess effort but has …

Rationale Previous work identified an attenuating effect of the matrix metalloproteinase
(MMP) inhibitor doxycycline on fear memory consolidation. This may present a new …

Associative learning involves complex interactions of multiple cognitive factors. While adult
subjects can articulate these factors verbally, for model animals such as macaques, we rely …
