Background: In recent years, internet- and mobile-based interventions (IMIs) have become increasingly relevant in mental health care and have sparked societal debates. Psychotherapists' perspectives are essential for identifying potential opportunities for improvement, facilitating conditions, and barriers to the implementation of these interventions.

Objective: This study aims to explore psychotherapists' perspectives on opportunities for improvement, facilitating conditions, and barriers to using IMIs.

Article Synopsis
  • The study analyzed frontal theta-band activity while participants learned a sequential arm movement through 192 trials over five practice sessions, focusing on the role of feedback in guiding performance.
  • Results showed that frontal theta power increased after negative feedback but decreased after extensive practice, indicating cognitive control needs and suggesting improvements in motor automatization.
  • It was found that while increased theta activity correlated with error correction, it did not predict the overall level of motor automatization, pointing to a potential separation between feedback processing and motor control attentional resources.

Complex lymphatic anomalies (CLA) are a group of conditions that pose diagnostic and therapeutic challenges due to their rarity and overlapping clinical findings. This case series describes the complex pathology and novel combination therapies of three patients diagnosed with various types of CLA. A retrospective review of medical records was performed for three patients treated for CLA between 2011 and 2019.

Several event-related potentials (ERPs) are associated with the processing of valence-dependent augmented feedback during the practice of motor tasks. In this study, 38 students learned a sequential arm-movement-task with 192 trials in each of five practice sessions (960 practice trials in total), to examine practice-related changes in neural feedback processing. Electroencephalogram (EEG) was recorded in the first and last practice session.

To examine the neural processing of valence-dependent augmented feedback, 38 students learned a sequential arm movement task with 192 trials in each of five practice sessions. The degree of motor automatization was tested under dual-task-conditions. Electroencephalogram (EEG) was recorded in the first and last practice session.
