The importance of identifying underlying process abnormalities in alexithymia: Implications of the three-process model and a single case study illustration.

We present an in-depth case study of a rare individual (whom we will refer to as "Jane") who reported an inability to experience emotion. Jane completed a range of assessments measuring alexithymia, emotional awareness, and emotion recognition ability. She, along with 22 control participants, also underwent skin conductance (SC) measurement and facial electromyography (EMG) during exposure to affective images, and self reported the valence/arousal of their responses to those images.

Healthcare Engineering Defined: A White Paper.

Engineering has been playing an important role in serving and advancing healthcare. The term "Healthcare Engineering" has been used by professional societies, universities, scientific authors, and the healthcare industry for decades. However, the definition of "Healthcare Engineering" remains ambiguous.

Emotional blunting associated with SSRI-induced sexual dysfunction. Do SSRIs inhibit emotional responses?

Anecdotal and published case reports suggest that some patients taking selective serotonin reuptake inhibitors (SSRI) experience diminution in emotional responsiveness. This study aims to define the individual components of emotion disturbed in these patients. Fifteen patients reporting SSRI-induced sexual dysfunction completed the Laukes Emotional Intensity Scale (LEIS), a questionnaire about various emotions.

The misclassification of blinks as saccades: implications for investigations of eye movement dysfunction in schizophrenia.

It is important to have a simple. accurate method for recording eye movements. Of the two popular approaches commonly adopted, electro-oculography (EOG) and infrared oculography (IROG), IROG is often accepted as the more accurate, and it is the method that is currently used most frequently to examine eye movements in schizophrenia.

Heritability of different measures of smooth pursuit eye tracking dysfunction: a study of normal twins.

Research studies have found that smooth pursuit eye movement dysfunction may serve as an index of genetic liability to develop schizophrenia. The heritability of various measures of smooth pursuit eye tracking proficiency and the saccades that occur during smooth pursuit was examined in 64 monozygotic (MZ) and 48 dizygotic (DZ) twin pairs. Two age cohorts were assessed (11-12 and 17-18 years of age).
