Robust and conventional neuropsychological norms: diagnosis and prediction of age-related cognitive decline.

The aim of the study was to compare the performance of Robust and Conventional neuropsychological norms in predicting clinical decline among healthy adults and in mild cognitive impairment (MCI). The authors developed Robust baseline cross sectional and longitudinal change norms from 113 healthy participants retaining a normal diagnosis for at least 4 years. Baseline Conventional norms were separately created for 256 similar healthy participants without follow-up.

Dissociation of cognitive and emotional empathy in adults with Asperger syndrome using the Multifaceted Empathy Test (MET).

Empathy is a multidimensional construct consisting of cognitive (inferring mental states) and emotional (empathic concern) components. Despite a paucity of research, individuals on the autism spectrum are generally believed to lack empathy. In the current study we used a new, photo-based measure, the Multifaceted Empathy Test (MET), to assess empathy multidimensionally in a group of 17 individuals with Asperger syndrome (AS) and 18 well-matched controls.

Knowing what others know, feeling what others feel: a controlled study of empathy in psychotherapists.

There has been considerable interest in assessing whether psychotherapists have enhanced abilities in empathy and whether those abilities influence treatment outcomes. However, to date, studies have been hindered by inconsistent definitions of empathy and a reliance on assessment via self-report. The unique aim of this study was to ascertain the empathic abilities of psychotherapists using a multidimensional battery consisting of objective and self-report measures.

Who cares? Revisiting empathy in Asperger syndrome.

A deficit in empathy has consistently been cited as a central characteristic of Asperger syndrome (AS), but previous research on adults has predominantly focused on cognitive empathy, effectively ignoring the role of affective empathy. We administered the Interpersonal Reactivity Index (IRI), a multi-dimensional measure of empathy, and the Strange Stories test to 21 adults with AS and 21 matched controls. Our data show that while the AS group scored lower on the measures of cognitive empathy and theory of mind, they were no different from controls on one affective empathy scale of the IRI (empathic concern), and scored higher than controls on the other (personal distress).

Introducing MASC: a movie for the assessment of social cognition.

In the present study we introduce a sensitive video-based test for the evaluation of subtle mindreading difficulties: the Movie for the Assessment of Social Cognition (MASC). This new mindreading tool involves watching a short film and answering questions referring to the actors' mental states. A group of adults with Asperger syndrome (n = 19) and well-matched control subjects (n = 20) were administered the MASC and three other mindreading tools as part of a broader neuropsychological testing session.

The 'amygdala theory of autism' revisited: linking structure to behavior.

The 'amygdala theory of autism' suggests a crucial role for the amygdala in the neurobiological basis of autism spectrum disorders. However, to date evidence is lacking of a direct relationship between amygdala measures and behavioral manifestations of autism in affected individuals. In 17 adult individuals with Asperger syndrome (AS) and 17 well-matched controls we therefore assessed associations between MRI-derived amygdala volume and behavioral variables of emotion recognition and social cognition, as well as with core AS symptomatology.

In search of "master mindreaders": are psychics superior in reading the language of the eyes?

Much of the effort to understand the brain substrate of theory of mind and empathy has involved the study of individuals with deficits in that domain, such as those on the autism spectrum. Studying individuals with presumed superior abilities in picking up social signals may yield important additional information. We predicted that psychic readers may have superior abilities and tested this by contrasting a group of 22 professional psychic readers with matched controls on a measure of theory of mind ("Reading the Mind in the Eyes" test) and a multidimensional measure of empathy [Interpersonal Reactivity Index (IRI)].

Hypertension and hypothalamo-pituitary-adrenal axis hyperactivity affect frontal lobe integrity.

Chronically elevated cortisol levels have been associated with elevated blood pressure, brain atrophy, and cognitive impairments. In this cross-sectional exploratory study, we assessed whether hypertension was related to hypothalamo-pituitary-adrenal axis hyperactivity and whether this may in part explain prefrontal brain atrophy and cognitive impairments in this population. We studied 27 patients with hypertension and 27 normotensive control subjects.
