“Here we developed a computational approach for estimating sulcal width and depth that relies on cortical surface reconstructions output by FreeSurfer. While other approaches for estimating sulcal morphology exist, studies often require the use of multiple brain morphology programs that have been shown to differ in their approaches to localize sulcal landmarks, yielding morphological estimates based on inconsistent boundaries.”
“Tomographic brain imaging has a rich iconography. Whilst figures are prepared for scientific communication (i.e., directed to other researchers) they also often end-up on magazine and journal covers (i.e., directed to a lay audience). Scientific figures should however not be just glossy illustrations of what is in the text.”
Reduced associative memory for negative information: impact of confidence and interactive imagery during study
“Although item-memory for emotional information is enhanced, memory for associations between items is often impaired for negative, emotionally arousing compared to neutral information. We tested two possible mechanisms underlying this impairment, using picture pairs: 1) higher confidence in one’s own ability to memorise negative information may cause participants to under-study negative pairs; 2) better interactive imagery for neutral pairs could facilitate associative memory for neutral pairs more than for negative pairs.”
“A common finding is that items associated with higher reward value are subsequently remembered better than items associated with lower value. A confounding factor is that when a higher value stimuli is presented, this typically signals to participants that it is now a particularly important time to engage in the task. […] Results converged on null effects of value on subsequent free recall accuracy. Re-analyses attributed Madan et al.’s value-bias to competition between choice items that were paired during learning. Value may not bias memory if it does not signal task importance or induce inter-item competition.”
It was great to speak on the Cognitive Neuroscience Society Trainee Professional Development Panel last week!
Here’s a link to the write-up about the event: A Note to Worried Graduate Students: There’s Still Hope.
In this special issue, we seek submissions on the influence of social, motivational, and emotional processes on learning and memory. Submissions are invited that address any subtype of learning and memory. Multi-method (e.g., integrating behavioral, patient, computational, electrophysiological, or neural measures) and developmental approaches are of particular interest.
Boon, bias or bane? The potential influence of reviewer recommendations on editorial decision-making
“No formal investigations have been conducted into the efficacy or potential influence of reviewer recommendations on editorial decisions, and the impact of this on the expectations and behaviour of authors, reviewers and journal editors. This article addresses key questions about this critical aspect of the peer review submission process. We suggest several future steps which could be taken towards improving the review process and make it more transparent, better understood, and fairer for all parties.”
