Putting your phone away to avoid distractions is much more difficult in the 2FA era.

@rayyantutunji.bsky.social showing at #SAA2025 that wearable data (EPA) is not enough to predict mental well-being (R2 = 0.01). My bet is more on timing (triggering) surveys compared to leaving out surveys.

Impressed by the commitment to correct validation (not even touching test set until later)!

Increased memory accuracy of previous mood states in depressed patients in daily life - Scientific Reports Scientific Reports - Increased memory accuracy of previous mood states in depressed patients in daily life

More contextual research can help explain these findings a bit better, but you can also find the article here: www.nature.com/articles/s41...

Finally, we checked whether participants' mood at recall influenced answers, and found this only in the never-depressed group. This shows the importance of context in measuring bias. but also the idea of only negative bias in depression may be inaccurate: perhaps its depressive realism? (4/n)

We also asked them to try remembering what their mood was during pervious timepoints to see how mood memory may differ, expecting depressed patients to report more negative memory of mood, and less positive compare to the never-depressed group ...(3/n)

An example is our recent paper on emotional memory in depression, where we followed up depressed, remitted, and never-depressed patients in daily life to see whether there is indeed a negative memory bias, and decreased positive bias. Using EMA, we asked the three groups to rate their mood...(2/n)

Wow! Just woke up to a lot of new followers, and not sure why, but feels like a good time to reintroduce myself. I'm a stress researcher with an interest in real-life dynamics and combining different methods (EMA, MRI, wearables)... (1/n)

Our new preprint shows how to estimate internal consistency reliability in EMA data:

➑️n~1150, 3 months data, 4 scales
➑️6 nomothetic & idiographic methods
➑️2 timescales (4/day & 1/week)
➑️2 languages (ENG vs NL)
➑️separation of between & within person reliability.

New preprint by @bsiepe.bsky.social & our WARN-D lab.

We collected information on sleep, tiredness & stress with both EMA and sensor data, and try to find out to which degree these are associated contemporaneously in a large dataset (n~800) with many timepoints (t~360).

No Evidence of Reliability Across 36 Variations of the Emotional Dot-Probe Task in 9,600 Participants - Irene Xu, Eliza Passell, Roger W. Strong, Elizabeth Grinspoon, LaneΓ© Jung, Jeremy B.

Paper alert: across 10k participants & 36 versions of the emotional dot probe task, task *reliability* cannot be distinguished from 0 (!).

Raises very serious questions about the literature (how did so many find positive relations between this task and other variables).

Imo, I think it comes down to what you expect stimuli to do. If you're interested in the stimulus driven activity, and not sustained activity (think oddball vs nback), an impulse function should be enough. Although consider modeling RT in this case: www.biorxiv.org/content/10.1...

Overall, wearables offer some added value that may recover signal from EMA noise, but more work is needed to examine these effects at a larger scale. Thanks for making it this far, heres a link to the paper and a cat gif. www.jmir.org/2023/1/e39995/

Finally, we wanted to see whether wearables offer any added value with respect to stress detection compared to EMA alone. While EMA models did better, combining both measures improved predictions! Moreover, idiographic approaches (LOBO) vastly outperformed nomothetic ones (LOSO). 4/n

So we did a time resolved analysis and saw that momentary arousal went up with stress...we end up seeing that arousal is of course not valence specific. Experiencing fewer positively valent emotions in the stress/exam week resulted in on average lower arousal 3/n

We first tried seeing how affect and physiological signals such as HR and skin conductance change in response to an ecological stressor. Oddly enough, we saw that arousal actually decreased during an exam week, which from the stress perspective of arousal was odd 2/n

Haven't posted here yet since joining, so here it goes: I am a psychologist/cognitive neuroscientist with a focus on developing predictive models and connecting lab and real-life assessments. An example is my first PhD Paper, where we use lab-based arousal measures for real-life stress detection 1/n
