I am beyond excited to announce that ggplot2 4.0.0 has just landed on CRAN.

It's not every day we have a new major #ggplot2 release but it is a fitting 18 year birthday present for the package.

Get an overview of the release in this blog post and be on the lookout for more in-depth posts #rstats

ggplot2 4.0.0

A new major version of ggplot2 has been released on CRAN. Find out what is new here.

Thanks @chelseakisil.bsky.social, totally agree! Mindfulness is such a key piece of the puzzle. Excited to see how future research from our group and the field at large might help bridge the gap between the attention economy and meaningful ways to refocus and reengage students.

Chelsea Kisil @chelseakisil.bsky.social · Jul 8

Love this. This is where my passion for mindfulness comes in: how can we expect interventions to be effective if the students aren't present with us?

I think attention has been seriously understudied in the science of learning literature. Someone extremely well-versed in this attention literature could really enhance how we think about learning, self-regulated learning, etc. #PsychSciSky #AcademicSky #EduSky

Thanks for the kind note about our paper @jeffgreene.bsky.social ! We have some emerging work that will be out soon addressing some of the points you raised. Happy to chat more if you’re interested.

We were thrilled to watch our client, @shawnschwartz.bsky.social, present his project using LABO at @stanford.edu Wu Tsai Human Performance Alliance!
We got to see how LABO can support research that tests boundaries of human performance. Thanks for showing us around campus! #Stanford #XRResearch

Moreover, new closed-loop methodologies allow real-time monitoring of attention, enabling interventions that adaptively deliver memory probes during optimal attentional states.

We consider how wider adoption of these approaches can inform causal investigations of attention-memory interactions. 6/N

Innovative techniques for real-time closed-loop interventions on attention (and cognition more broadly). Real-time causal intervention studies require constructing and validating a robust (a, left) trial-by-trial pipeline to measure, clean, evaluate, and act on psychophysiological assays in real-time, which then can be used to manipulate the stimulus display, such as that for an (a, right) adaptive memory task with real-time attention tracking and reorienting. Example approaches for the real-time evaluation of psychophysiological assays of attention include (b, left) pupillometry (c, left; e.g., pupil-size dilation or constriction that surpasses a real-time adaptive baseline pupil threshold), (b, middle) scalp EEG (c, middle; e.g., elevated posterior alpha power), and (b, right) functional MRI (c, right; e.g., pattern-classifier decoding of attentional state).

Memory precision — the fidelity of remembered details — tends to decline with age.

Recent advances in measurement techniques provide more sensitive ways to assess how attentional and memory processes change across the lifespan. 5/N

Example episodic memory precision task. Participants encounter (a, top) objects shaded in one of 360 possible colors. Participants then encounter (a, bottom) a grayscale version of previously encountered objects and indicate their memory for the color of the object by clicking the corresponding color on the wheel. Illustrative distributions of (b) memory precision errors are mapped from the circular space to the linear space of −180 to +180. Here, young adults (blue dashed line) are schematized to demonstrate higher memory precision than older adults (solid red line).

In fact, emerging work suggests that memory encoding and retrieval may be phase-dependent, aligning with hippocampal and/or neocortical theta oscillations.

We review evidence that memory performance can vary systematically with these rhythms. 4/N

Three types of modeled or observed neural theta oscillations. The schematic shows (a) the SPEAR model of hippocampal theta, (b) neocortical theta power (which may or may not relate to theta oscillations in the frontoparietal cortex and/or hippocampus), and (c) theta-specific oscillations in reinstated (i.e., retrieved) episodic content (as quantified by pattern-classifier evidence in neural data). (SPEAR = separate phases of encoding and retrieval).

But how are the temporal dynamics of attention related to whether and how we remember?

It turns out that attention fluctuates rhythmically⚡️, particularly in the theta (4–7 Hz) and alpha (8–12 Hz) ranges.

This raises the possibility that episodic memory behavior may also exhibit rhythmicity. 🤔 3/N

Attention and episodic memory interact closely:

* Goal-directed (top-down) attention helps prioritize relevant information.

* Stimulus-driven (bottom-up) attention responds to salient events.

We discuss how these systems shape memory encoding and retrieval. 2/N

Assessing the influence of attention on memory retrieval. Shown in (a) are the frontoparietal networks of attention and cognitive control derived from network parcellations computed from the full sample (N = 1,000) in Yeo et al. (2011). (DAN = dorsal attention network; VAN = ventral attention network; CCN = cognitive control network).

Shawn Schwartz @shawnschwartz.bsky.social · Jun 5

How do different forms of attention, their neural mechanisms, and related cognitive control processes influence what we learn and remember?

Recent methodological and theoretical advances are offering new insights into the relationship between attention and episodic memory. 1/N

The schematic of the goal-directed memory-retrieval task used in Madore et al. (2020) shows (b) that pre-goal lapsing was measured using EEG posterior alpha power and pupil size in the last 1 s of the ITI, whereas goal-coding strength was measured using a retrieval goal-cue-locked ERP extracted from a midfrontal cluster of electrodes. In (c) the 1 second prior to the onset of the retrieval goal cue, pupil size (and posterior alpha power; not shown) significantly correlated with retrieval success, and midfrontal EEG goal-coding strength partially mediated this effect (n = 75; Madore et al., 2020).

I've already had two federal grants terminated and face a 33% pay cut due to future terminations. It's painful, but not as painful as the conversations I'm having every day with brilliant trainees in graduate school and postdoctoral positions who see little future for themselves in US science.

Are you tempted to orthogonalize the regressors in your fMRI model? @jeanette-mumford.bsky.social tells you why this is almost never a good idea, and is likely to wreck the interpretation of your model. mumfordbrainstats.tumblr.com/post/1337933...

Collinearity...is orthogonalization the answer? (No)

If I had a dollar for every time I read a paper purporting to have repaired a multicollinearity issue by orthogonalizing regressors... Unfortunately, once collinearity is there and the data have been...
