Dose-related effects of ketamine for antidepressant-resistant symptoms of posttraumatic stress disorder in veterans and active duty military: a double-blind, randomized, placebo-controlled multi-center clinical trial.

This study tested the efficacy of repeated intravenous ketamine doses to reduce symptoms of posttraumatic stress disorder (PTSD). Veterans and service members with PTSD (n = 158) who failed previous antidepressant treatment were randomized to 8 infusions administered twice weekly of intravenous placebo (n = 54), low dose (0.2 mg/kg; n = 53) or standard dose (0.

Vive La France: Three Delusional Disorders Originally Reported in the French Medical Literature.

Delusions as a feature of psychosis have long captured the fascination of both psychiatry and the public at large. The French first described three famous delusions: the Cotard delusion, folie à deux, and Capgras delusion. In this article, we examine a case illustrating each delusion and the hallmark features of each as well as a brief discussion about the current understanding of these disorders.

Does adding an emotion component enhance the Triple P-Positive Parenting Program?

This pilot study aimed to compare the efficacy of a regular offering of the group-delivered Triple P-Positive Parenting Program for child behavior problems with an enhanced version tailored to promote child emotion competence. Families of children between ages 3 and 6 years displaying early-onset conduct problems were randomly assigned to Group Triple P (GTP; final n = 18) or Emotion Enhanced Triple P (EETP; final n = 18), in which parents were encouraged to incorporate emotion labels and causes and to coach emotion competence during discussions of everyday emotional experiences with their child. Compared with parents who received GTP, parents who received EETP increased their discussion of emotion labels and emotion causes in conversations with their child at postintervention, but this advantage was lost by the 4-month follow-up.

Verbal description benefits for faces when description conditions are unknown a priori.

Some prior research has shown a benefit for describing nonverbal study stimuli, particularly faces, on a later recognition test relative to a control (no description) condition. In such studies, participants have known a priori whether a stimulus will need to be described, meaning that encoding differences other than the description could account for the effect. In Experiment 1, a description benefit was obtained for faces that could not be attributed to encoding differences.

Talking and driving: applications of crossmodal action reveal a special role for spatial language.

Talking reduces attention resulting in real-world crash risks to drivers that talk on a phone and drive. Driving is a behavior that is very demanding on spatial attention, suggesting potentially large interference by spatial codes in language. The current study investigated how different types of verbal codes influence visual attention during dual-task performance.
