Auditory hallucinations in acute stroke

Auditory hallucinations are uncommon phenomena which can be directly caused by acute stroke, mostly described after lesions of the brain stem, very rarely reported after cortical strokes. The purpose of this study is to determine the frequency of this phenomenon. In a cross sectional study, 641 stroke patients were followed in the period between 1996-2000. Each patient underwent comprehensive investigation and follow-up. Four patients were found to have post cortical stroke auditory hallucinations. All of them occurred after an ischemic lesion of the right temporal lobe. After no more than four months, all patients were symptom-free and without therapy. The fact the auditory hallucinations may be of cortical origin must be taken into consideration in the treatment of stroke patients. The phenomenon may be completely reversible after a couple of months.     

Why don't we believe non-native speakers? The influence of accent on credibility

Non-native speech is harder to understand than native speech. We demonstrate that this “processing difficulty” causes non-native speakers to sound less credible. People judged trivia statements such as “Ants don't sleep” as less true when spoken by a non-native than a native speaker. When people were made aware of the source of their difficulty they were able to correct when the accent was mild but not when it was heavy. This effect was not due to stereotypes of prejudice against foreigners because it occurred even though speakers were merely reciting statements provided by a native speaker. Such reduction of credibility may have an insidious impact on millions of people, who routinely communicate in a language which is not their native tongue.     

Clarifying the Relationship of Parental Bonding to Suicide Ideation and Attempts

Suicide and suicidal behavior are major public health problems, especially among adolescents and young adults. Previous research has established links between parental bonding and suicidality; however, it remains unclear whether parental bonding is associated with suicide ideation, the progression from suicide ideation to suicide attempts, or both. This study examined the relation of parental bonding to suicide ideation and suicide attempts in adolescents from two settings: (1) acute psychiatric care (n = 172) and (2) high school (n = 426). All participants were administered validated measures of parental bonding, suicide ideation, and suicide attempts, as well as emotion dysregulation, loneliness, and self‐worth. In the psychiatric sample, lower parental care significantly differentiated adolescents with a history of suicide attempts from those with suicide ideation only or without histories of suicidality. This pattern remained even after controlling for other known correlates of suicidality (i.e., emotional dysregulation, loneliness, and low self‐worth). Similar effects were found in the community sample, although these findings failed to reach statistical significance. In both samples, parental overprotection was not associated with suicide ideation or suicide attempts. Results suggest that parental care may be an important risk factor for youth suicidal behavior and may help differentiate suicide attempters from suicide ideators.
