The role of emotional content in segmenting naturalistic videos into events Open
The human mind automatically divides continuous experience into meaningful events (event segmentation). Despite abundant evidence that some kinds of situation changes (e.g., action, goal, or location changes) contribute to event segmentati…

Event segmentation and encoding rely on information accumulated over different temporal scales Open
People spontaneously divide experience into discrete units (event segmentation) that shape episodic memory. Prominent accounts of segmentation suggest that it reflects mechanisms that update mental representations of the ongoing situation …

Locus coeruleus hyperactivity in middle age may be associated with better cognitive performance Open
Background Measuring the health of the locus coeruleus (LC), the brainstem site of the first cellular damage in Alzheimer’s Disease (AD) pathogenesis, is of particular interest for early diagnosis. In both rodents and humans (Elman 2017; K…

Locus coeruleus neuromelanin accumulation and dissipation across the lifespan Open
The pigment neuromelanin, produced in the locus coeruleus (LC) as a byproduct of catecholamine synthesis, gives the “blue spot” its name, and both identifies LC neurons and is thought to play an important yet complex role in normal and pat…

Attention-dependent coupling with forebrain and brainstem neuromodulatory nuclei changes across the lifespan Open
Attentional states continuously reflect the predictability and uncertainty in one’s environment having important consequences for learning and memory. Beyond well known cortical contributions, rapid shifts in attention are hypothesized to …

Temporal Attention Modulates EEG Spectral Correlates of Successful Memory Encoding Open
Variability in attention can influence episodic encoding across multiple time scales. Here we investigate whether this variability can be captured in neural subsequent memory effects. In a scalp EEG study, participants memorized lists of w…

The Attentional Boost Effect in Free Recall Dynamics Open
With the Attentional Boost Effect (ABE), responding to a briefly presented target in a detection task enhances the encoding of other items presented at the same time. However, the effects of target detection on context memory for the event…

Grounding the Attentional Boost Effect in Events and the Efficient Brain Open
Attention and memory for everyday experiences vary over time, wherein some moments are better attended and subsequently better remembered than others. These effects have been demonstrated in naturalistic viewing tasks with complex and rela…

Auditory Target Detection Enhances Visual Processing and Hippocampal Functional Connectivity Open
Though dividing one’s attention between two input streams typically impairs performance, detecting a behaviorally relevant stimulus can sometimes enhance the encoding of unrelated information presented at the same time. Previous research h…

Drift Diffusion Modeling of Intentional and Incidental Temporal Selection of Behaviorally Relevant Moments Open
When targets appear in a detection task, unrelated but concurrent stimuli will gain a boost in relational memory, the ability to remember the spatial and temporal relationship between items (Turker & Swallow, 2019). This may reflect enhanc…

Estimates of locus coeruleus function with functional magnetic resonance imaging are influenced by localization approaches and the use of multi-echo data Open
The locus coeruleus (LC) plays a central role in regulating human cognition, arousal, and autonomic states. Efforts to characterize the LC's function in humans using functional magnetic resonance imaging have been hampered by its small siz…

Measuring Events: An Investigation into the Stability of Event Segmentation Patterns Across Groups Open
People spontaneously divide everyday experience into smaller units (event segmentation). To measure event segmentation, studies typically ask participants to explicitly mark the boundary between events as they watch a movie (segmentation t…

Culture influences how people divide continuous sensory experience into events. Open
Everyday experience is divided into meaningful events as a part of human perception. Current accounts of this process, known as event segmentation, focus on how characteristics of the experience (e.g., situation changes) influence segmenta…
