Ecologically valid indicators of executive functions are designed to capture dysfunction not easily measured in a lab setting. Here, we present two studies on the development and validity analyses of a behavioral screener for executive functions among young adults. In Study 1, we derived a four-factor (problem solving, attentional control, behavioral control, and emotional control) behavioral screener using a sample of 765 individuals. We used invariance analyses to evaluate the screener's measurement reliability across sex. In Study 2, we replicated the screener derivation analyses using an independent sample of 197 undergraduates. To further examine the screener's validity, we evaluated it against a well-known executive functions rating scale. The four-factor model was supported in both samples and analyses provided support for this screener as a valid and reliable measure for everyday executive functions among young adults.

Introduction: Detrusor contractions can be classified as either volitional or involuntary. The latter are a hallmark of urge urinary incontinence. Understanding differences in neuroactivation associated with both types of contractions can help elucidate pathophysiology and therapeutic targets.

Introduction: Numerous studies have explored the linguistic and executive processes underlying verbal fluency using association designs, which provide limited evidence. To assess the validity of our model, we aimed to refine the cognitive architecture of verbal fluency using an interference design.
Methods: A total of 487 healthy participants performed letter and semantic fluency tests under the single condition and dual conditions while concurrently performing a secondary task that interferes with speed, semantics, phonology, or flexibility.

Background: Proton therapy (PRT) is an innovative radiotherapeutic modality for the treatment of cancer with unique ballistic properties. The depth-dose distribution of a proton beam reduces exposure of healthy tissues to radiations, compared with photon-therapy (XRT). To date, only few indications for proton-therapy, like pediatric cancers, chordomas, or intra-ocular neoplasms, are reimbursed by Health systems.
