Prolonged Exposure for PTSD in a Veteran group: a pilot effectiveness study.

Previous research has consistently demonstrated that Prolonged Exposure (PE) therapy is an effective treatment for posttraumatic stress disorder (PTSD). Traditionally, PE has been studied and delivered on an individual basis. However, the growing number of Veterans in need of PTSD treatment has led to increased interest in group therapies as an efficient way to provide access to care.

Implicit learning, thought-focused attention and obsessive-compulsive disorder: a replication and extension.

Although significant empirical support exists for both cognitive and neurobiological models of obsessive-compulsive disorder (OCD), there have been few efforts to integrate findings. In this investigation, we attempted to link models by examining relationships between performance on information processing tasks posited to be markers of OCD-related neuropathology and a self-report measure of excessive thought-focused attention (cognitive self-consciousness; CSC). Congruent with predictions and prior research, OCD patients' performance was impaired in comparison to an anxious control group on the Serial Reaction Time (SRT) Task, a measure of implicit procedural learning.

Diurnal changes in water conduction in loblolly pine (Pinus taeda) and Virginia pine (P. virginiana) during soil dehydration.

We studied diurnal changes in water conduction during soil dehydration in 37-month-old seedlings of one Virginia pine (Pinus virginiana Mill.) and two loblolly pine (P. taeda L.
