In this study, we objectively tracked the duration, frequency, and the preferred practices chosen by novice mindfulness practitioners following a mindfulness meditation (MM) intervention. A sample of 55 mildly stressed participants, aged 50 to 80 years old, underwent an individual 6-week MM intervention and had their guided meditation home practice electronically recorded during the intervention and the 8-week post-intervention period. Participants’ psychological well-being was assessed through self-report measures of mindfulness, quality of life, and symptoms of depression and stress. Results evidenced a high adherence to practice, with an average of ~23 minutes per day during the intervention and ~16 minutes per day in the follow-up period. Body scan, sitting meditation, and breathing space were the most popular meditation practices among participants. Our results showed significant alterations in self-reported measures over time, suggesting improvements in stress and overall quality of life. Changes in the self-report measures did not correlate with MM practice time, which suggests that other psychological phenomena, including quality of meditation practice, influence these outcomes.

Given widespread use of spike antibody in generating coronavirus disease vaccines, SARS-CoV-2 nucleocapsid antibodies are increasingly used to indicate previous infection in serologic surveys. However, longitudinal kinetics and seroreversion are poorly defined. We found substantial seroreversion of nucleocapsid total immunoglobulin, underscoring the need to account for seroreversion in seroepidemiologic studies.

Mind-wandering is a form of off-task attention that has been associated with negative affect and rumination. The goal of this study was to assess potential electroencephalographic markers of task-unrelated thought, or mind-wandering state, as related to error rates during a specialized cognitive task. We used EEG to record frontal frequency band activity while participants completed a Stroop task that was modified to induce boredom, task-unrelated thought, and therefore mind-wandering. A convenience sample of 27 older adults (50-80 years) completed a computerized Stroop matching task. Half of the Stroop trials were congruent (word/color match), and the other half were incongruent (mismatched). Behavioral data and EEG recordings were assessed. EEG analysis focused on the 1-s epochs prior to stimulus presentation in order to compare trials followed by correct versus incorrect responses. Participants made errors on 9% of incongruent trials. There were no errors on congruent trials. There was a decrease in alpha and theta band activity during the epochs followed by error responses. Although replication of these results is necessary, these findings suggest that potential mind-wandering, as evidenced by errors, can be characterized by a decrease in alpha and theta activity compared to on-task, accurate performance periods.

The assumption has become that memory for words' sound patterns, or form, is rapidly lost in comparison to content. Memory for form is also assumed to be verbatim rather than schematic. Oral story-telling traditions suggest otherwise. The present experiment investigated if form can be remembered schematically in spoken poetry, a context in which form is important. We also explored if sleep could help preserve memory for form. We tested whether alliterative sound patterns could cue memory for poetry lines both immediately and after a delay of 12 hours that did or did not include sleep. Twelve alliterative poetry lines were modified into same alliteration, different alliteration, and no alliteration paraphrases. We predicted that memory for original poetry lines would be less accurate after 12 hours, same alliteration paraphrases would be falsely recognized as originals more often after 12 hours, and that the no-sleep group would make more errors. Different alliteration and no alliteration paraphrases were not expected to share this effect due to schematically different sound patterns. Our data support these hypotheses and provide evidence that memory for form is schematic in nature, retained in contexts in which form matters, and that sleep may help preserve memory for sound patterns.
