The etiology and pathophysiology of seasonal affective disorder (SAD) has been linked to the seasons and to light since its first conceptualization. Aspects of SAD that make it particularly amenable to biological investigation include the predictable recurrent episodes, the rapid response to a nonpharmacologic treatment, the specific neurovegetative features, and the availability of rich animal...

An important task in Information Systems research is to understand factors that influence the continuous use of information technology (IT). This study extends the literature by conceptualizing a construct called IT attachment to explain the phenomenon. Drawing upon the attachment theory in developmental and social psychology, it suggests that IT attachment, defined as an affective bond of the ...

This project augments an existing intelligent tutoring system (AutoTutor) that helps learners construct explanations by interacting with them in natural language and helping them use simulation environments. The research aims to develop an agile learning environment that is sensitive to a learner’s affective state, presuming that this will promote learning. We integrate state-of-the-art, nonint...

We report the results of a pilot study that compared the computer self-efficacy construct with metacognition. While self-efficacy is primarily affective and refers to one’s beliefs about one’s ability to perform a task, metacognition is primarily cognitive and refers to one’s thoughts about one’s ability to perform a task. Given their similarity, both have been used as surrogate measures of kno...

Moral sensitivity is the first component of the 4-component moral action process (J. R. Rest, 1986). The author reviews moral sensitivity operationalization and measurement across multiple samples and domains. She reviews 3 definitions of the construct (i.e., recognition and affective response, recognition, and recognition and ascription of importance) and measurement instruments based on these...

To date, little research has been done on the role of emotions with respect to computer related behaviours. The purpose of this study was to develop a reliable, valid scale to assess emotions while learning with computers. Four emotions (anger, anxiety, happiness, and sadness), selected after a detailed review of the research, were evaluated. Internally reliability estimates were acceptable. Co...

OBJECTIVE Psychological and neural mechanisms of the affective dimension of pain are known to be disturbed in patients with chronic pain disorder. The aim of this functional magnetic resonance imaging study was to assess the neurofunctional and behavioral measures underlying the ability to construct pain-related affective meaning in a painful situation by comparing 21 clinically and psychometri...

BACKGROUND This study investigates whether an analysis, based on Item Response Theory (IRT), can be used for initial evaluations of depression assessment instruments in a limited patient sample from an affective disorder outpatient clinic, with the aim to finding major advantages and deficiencies of the instruments. METHODS Three depression assessment instruments, the depression module from t...

Asymmetrical activity over the frontal cortex has been implicated in the experience and expression of emotions and motivations. Explanations of the research have suggested that relatively greater left frontal activity is associated with positive affect and/or approach motivation, and that relatively greater right frontal activity is associated with negative affect and/or withdrawal motivation. ...
