Rethinking the definition of episodic memory

“The definition of episodic memory, as proposed by Tulving, includes a requirement of conscious recall. As we are unable to assess this aspect of memory in nonhuman animals, many researchers have referred to demonstrations of what would otherwise be considered episodic memory as ‘episodic-like memory.’ Here the definition of episodic memory is reconsidered based on objective criteria.”

Editorial: Into a new decade

New editorial from Behavior Research Methods, providing an overview of the journal and what articles we publish.

“The journal is the premier place that researchers turn to for advice on which stimuli to use and how to present them, on how to measure responses, and on how to analyze data properly. The best way to guarantee this is by making sure that our articles are useful to the questions and needs that researchers have.”

Exploring word memorability: How well do different word properties explain item free-recall probability?

“What makes some words more memorable than others? Words can vary in many dimensions, and a variety of lexical, semantic, and affective properties have previously been associated with variability in recall performance. […] Here, I consider how well 20 different word properties—across lexical, semantic, and affective dimensions—relate to free recall.”

Science of Learning Strategy Series: Article 1, Distributed Practice

First paper in a new articles series, with Tom Van Hoof and Megan Sumeracki!

“Distributed practice is an evidence-based, learning-science strategy that is relevant to the planning and implementation of continuing professional development (CPD). Spacing-out study or practice over time allows the brain multiple opportunities to process new and complex information in an efficient way, thus increasing the likelihood of mastery and memory.”

Age-related differences in myeloarchitecture measured at 7 T

First paper out with collaborators at the SPMIC!

“We have used the magnetisation transfer (MT) MRI measure as a primary measure of myelination in both the gray matter (GM) regions of the brain, and the underlying white matter in each region, in a cohort of healthy adults (aged 19–62 year old). We also explored the possibility of using the Nuclear Overhauser Enhancement (NOE) effect, which is acquired in a similar method to MT, as an additional measure of myelination.”

Special issue for Cognition on social, motivational, and emotional influences on memory

Our special issue in Cognition is now complete!

“[…] we highlight three major themes that emerge from this special issue. First, we discuss how affective influences on memory are better characterized as a transformation in the structure of memories rather than simple enhancements. Second, we discuss how affective and social contexts influence memory encoding and retrieval strategies. Finally, we discuss how affective influences on memory are shaped by how individuals interpret environmental cues.”

Presentations at NOWCAM 2020

Six presentations at NOWCAM 2020 on on-going collaborative projects with Daniela Palombo and students in her lab!

“Semi-automated processing of autobiographical memory narratives”

“Emotion and elaboration: The impact of emotion on autobiographical memory recall”

“Generalization of emotion: The transfer of negative valence to novel episodes”

“Exploration of retrograde effects of emotion on memory”

“Retrograde effects of emotion on memory for related events”

“Can imagining the future increase pro-environmental tendencies?”

Development and decay of procedural skills in surgery: A systematic review of the effectiveness of simulation-based medical education interventions

First medical education paper in collaboration with Rakesh Patel!

“Changes to surgical training programmes in the UK has led to a reduction in theatre time for trainees, and an increasing reliance on simulation to provide procedural experience. Whilst simulation offers opportunity for repetitive practice, the effectiveness of simulation as an educational intervention for developing procedural surgical skills is unclear.”

Considerations for Comparing Video Game AI Agents with Humans

Here I discuss some considerations and approaches for making AI agents comparable to humans–with an emphasis on AlphaStar, Atari 2600 AI agents, Rubik’s Cube solving algorithms, and AlphaGo.

Like comparative psychology, but with machines. I consider this my first “robot psychology” paper.

Semi-automated transcription and scoring of autobiographical memory narratives

New paper with Daniela Palombo and students in her lab!

“Autobiographical memory studies conducted with narrative methods are onerous, requiring significant resources in time and labor. […] Specifically, here we lay out a procedure that guides researchers through the four main phases of the autobiographical narrative pipeline: (1) data collection, (2) transcribing, (3) scoring, and (4) analysis.”

Virtual patients will help train future medics

Experts from the University of Nottingham and Isabel Healthcare will create an online learning platform enabling medical students and junior doctors to develop essential skills, even without face-to-face time with patients, thanks to funding from Innovate UK.

The funding will allow experts to create a learning platform using a unique combination of virtual cases and AI powered clinical decision support technology, that will help them to develop the knowledge, problem-solving and decision-making skills they need.

Neuromatch talk

Dr. Madan gave a short talk at Neuromatch 2.0, providing an overview of the fractal dimensionality work.
