Drug Liaison Midwives: An Innovation for Addressing Perinatal Substance Use
(Elsevier, 2026-02) Hanson, Marcy N.; Lawson, Margaret; Sinclair, Hazel
In this commentary, we explore the innovative practices of specialized midwives in Scotland to help support the care of people who use substances while pregnant. By examining the historical context and current trends related to perinatal substance use, we highlight the significant progress the Vulnerable in Pregnancy program has achieved in enhancing care for vulnerable childbearing populations and identify opportunities for replicating these practices in the United States. Noting an increase in heroin use among pregnant women in the 1990s, a community midwife in Scotland sought to change midwifery practice. Due to this midwife’s dedication, perinatal substance use care in her community has changed and evolved into interdisciplinary practices that improve maternal and infant outcomes.
Can goal reminders reduce the Stroop effect in older adults
(American Psychological Association, 2025-02) Welhaf, Matthew S.; Valdez, Madeline R.; Charbonneau, Brooke; Hood, Audrey V. B.; Hutchison, Keith A.; Bugg, Julie M.
Previous research has demonstrated robust age-related differences in the Stroop effect. Such differences are often attributed to deficits in cognitive control processes, such as goal maintenance ability. Previous research in younger adults has reliably demonstrated that the magnitude of the Stroop effect, particularly for those lower in working memory capacity, can be reduced by providing periodic goal reminders. The present study tested if this benefit of goal reminders extends to another group with reduced goal maintenance ability, older adults. Younger (N = 80) and older (N = 78) adults completed a vocal color-word Stroop task in which most trials were congruent, a condition which induces goal neglect and exacerbates Stroop effects. Critically, half of the participants in each age group were stopped every 24 trials to vocalize either a goal-reminder statement (“The goal is to name the color, not the word”) or a nongoal statement (“This is part of my psychology study”). The key finding was that the goal reminders benefitted older adults as evidenced by a reduced Stroop effect in reaction time for the goal condition compared with the nongoal condition. This pattern was not observed for younger adults. Error rate analyses suggested that the benefits of goal reminders were short-lived, with errors primarily reduced in the first half of the run (e.g., 12 trials) following goal reminders. We suggest that goal reminders can be a useful intervention to momentarily improve cognitive control in older adults. We discuss the implications of this finding for theories of cognitive control that implicate reductions in goal maintenance at the center of age-related cognitive decline.

Examining the time course of post collaborative benefits across word lists and prose passages
(Springer Science and Business Media LLC, 2024-07) Wei, Yunfeng; Charbonneau, Brooke; Meade, Michelle L.; Hutchison, Keith A.
In the current study, we investigated how long the effects of one single collaboration session continue to influence individual memory. Participants learned categorized word lists and prose passages individually, and then they were instructed to recall learned materials either collaboratively or individually. Following initial recall, participants completed an individual recall test after a delay of 5 min, 48 h, or 1 week. On the initial recall test, we found that collaboration reduced recall of correct items on both word lists and prose passages (collaborative inhibition), and that collaboration reduced false recall on both word lists and prose passages (error correction). However, on the subsequent individual memory test after a delay, the pattern of post collaborative effects differed across veridical and false recall. For both word lists and prose passages, post collaborative benefits on correct recall lasted 1 week. However, there were no lasting effects of error correction on subsequent false recall. These results suggest that the time course of post collaborative benefits can be long lasting, but they are selective to veridical recall. The results are explained by theories of reexposure and error correction.
The effect of individual visual sensitivity on time perception
(Springer Science and Business Media LLC, 2025-02) Růžičková, Alexandra; Jurkovičová, Lenka; Páleník, Julie; Hutchison, Keith A.; Chmelík, Jiří; Mitterová, Kristína; Juřík, Vojtěch
The human mind, trying to perceive events coherently, creates the illusion of continuous time passage. Empirical evidence suggests distortions in subjectively perceived time flow associated with well-studied neural responses to sensory stimuli. This study aimed to investigate whether visually uncomfortable patterns, causing exceptionally strong brain activation, affect short time estimates and whether these estimates vary based on the overall reported sensory sensitivity and cortical excitability of individuals. Two experiments in virtual reality testing our assumptions at different levels of complexity of timed stimuli provided initial insight into the studied processes in highly controlled and realistic conditions. Data analysis results did not support our hypotheses, but showed that subjectively most visually uncomfortable simple patterns, i.e., achromatic gratings, cause more variable temporal judgments. Supposedly, this inaccuracy depends on the currently perceived visual comfort and thus the current visual system sensitivity, which cannot be satisfactorily derived from trait-based measures. The exploration of the effect of complex stimuli, i.e., virtual exteriors, suggested that their visual comfort does not affect time perception at all. Biological sex was an important variable across experiments, as males experienced temporal compression of stimuli compared to females. Neuroimaging research is needed for a deeper investigation of the origin of these results.
Relationships between Patient-Reported Outcomes and Predictors of Second ACL Injuries during Unanticipated Jump Landings
(Ovid Technologies, 2024-11) Monfort, Scott M.; Aflatounian, Fatemeh; Fischer, P.; Becker, James; Hutchison, Keith A.; Simon, Janet E.; Grooms, Dustin R.
Reactive and external visual-cognitive demands are prevalent in sport and likely contribute to ACL injury scenarios. However, these demands are absent in common return-to-sport assessments. This disconnect leaves a blind spot for determining when an athlete can return to sport with mitigated re-injury risk. PurposeTo characterize relationships between patient-reported outcome measures (PROMs) and cognitive-task interference (i.e., cognitive demands exacerbating neuromuscular impairments) for biomechanical predictors of second ACL injuries during jump landings that involved rapid unanticipated decision making. MethodsThirty-six persons following primary ACLR (26F/10M, 19.8±1.8 years; 1.71±0.1 m; 69.6±12.8 kg, 1.5±0.6 years post ACLR; Tegner: 6.8±1.8) participated. PROMs of ACL-RSI, and the Forgotten Joint Score-12 Knee (FJS-12) were selected to assess altered psychological state (e.g., confidence, attention toward knee). Jumping tasks under anticipated and unanticipated secondary jump directions were performed. Biomechanical variables were dual-task changes (unanticipated - anticipated) in 1) uninvolved limb hip rotator impulse (DTC_Uni-HRot_Imp), 2) asymmetry of knee extensor moment at initial contact (DTC_KEM_Asym), and 3) range of involved knee abduction angle (DTC_KAbA_Range). Regression models tested for relationships between PROMs and the dual-task change in biomechanical variables. Results: ACL-RSI (DTC_Uni-HRot_Imp (p < 0.001)) and FJS-12 (DTC_KAbA_Range (p = 0.001)) had significant relationships with dual-task change in the opposite direction as expected (worse PROM ➔ less dual-task change). A follow-up analysis indicated that dual-task change was inversely correlated with the baseline estimates for kinetic biomechanical variables (less risky single-task biomechanics ➔ greater dual-task change for Uni-HRot_Imp and KEM_Asym).Conclusions: The collective results are consistent with higher functioning participants (better PROMs) who also demonstrate desirable biomechanics during single-task conditions being prone to demonstrating the greatest risk-associated DTC in unanticipated scenarios.
