The present study investigated the role of inhibition in peripheral cueing by nonpredictive cues. Based on past findings, we investigated the possibility that inhibition of learned irrelevant cue colors is typical of short cue-target intervals, with more competition for attention capture between cue versus target. In line with the expectation, in a modified contingent-capture protocol, with short cue-target intervals, we found same-location costs (SLCs) - that is, disadvantages for validly cued targets (cue = target position) compared to invalidly cued targets (cue ≠ target position) with consistently colored non-matching cues.

Action-imagery-practice refers to the repetitive use of action imagery to improve subsequent performance leading to partially different representation types than action-execution-practice (AEP). This study explored the representation types in kinesthetic action-imagery-practice (K-AIP) and visual action-imagery-practice (V-AIP) in a serial reaction time task using the crossed hand transfer paradigm. 169 participants (age M ± SD = 25.

Article Synopsis
  • The research aimed to determine how common different visual imagery abilities—aphantasia, hypophantasia, typical imagery, and hyperphantasia—are in a large multinational group of people.
  • In the first study, 3,049 participants completed a questionnaire, revealing that 1.2% had aphantasia, 3% had hypophantasia, 89.9% had typical imagery ability, and 5.9% had hyperphantasia.
  • A second study combined these results with additional data from previous studies, confirming similar prevalence rates in a larger sample of 9,063 participants, thus providing a comprehensive understanding of visual imagery abilities.

Gas flow is fundamental for driving tidal ventilation and, thus, the speed of lung motion, but current bias flow settings to support the preterm lung after birth do not have an evidence base. We aimed to determine the role of gas bias flow rates to generate positive pressure ventilation in initiating early lung injury pathways in the preterm lamb. Using slower speeds to inflate the lung during tidal ventilation (gas flow rates 4-6 L/min) did not affect lung mechanics, mechanical power, or gas exchange compared with those currently used in clinical practice (8-10 L/min).
