We propose a new instructional theory, the Domain of Validity (DoV) Framework, which offers a new way forward for designing teaching for conceptual change, while also resolving conflicts between existing theories related to common, difficult-to-change conceptions students have about particular scientific topics. We propose that knowledge consists…

The authors describe the development and initial validation of a home-based version of the Laboratory Temperament Assessment Battery (Lab-TAB), which was designed to assess childhood temperament with a comprehensive series of emotion-eliciting behavioral episodes. This article provides researchers with general guidelines for assessing specific…

Hopelessness has become an increasingly important construct in palliative care research, yet concerns exist regarding the utility of existing measures when applied to patients with a terminal illness. This article describes a series of studies focused on the exploration, development, and analysis of a measure of hopelessness specifically intended…

In this article, we suggest an instructional intervention to help students understand statements involving multiple quantifiers in logical contexts. We analyze students' misinterpretations of multiple quantifiers related to the epsilon-N definition of convergence and point out that they result from a lack of understanding of the significance of…

In this largely theoretical article, we discuss the relation between a kind of affect, behavioural schemas and aspects of the proving process.

We then mention the position of feelings…

This article provides an overview of pediatric sleep disturbances with emphases on types and treatments. Relationships between sleep disorders and comorbid conditions function to exacerbate and maintain both disorders. An estimated 20% of teenagers experience chronic partial sleep deprivation, resulting in problems with memory, attention, and…

The authors describe the development and psychometric properties of the Korean Mood State Inventory (KMSI), which is designed to measure the mood states of Korean college students. Factor structure, concurrent validity, and internal consistency of the KMSI scores are reported. Implications, limitations, and recommendations for future research are…

In this monograph, the authors have brought the findings of the English and Romanian Adoptee (ERA) study up to age 15 years and, in so doing, have focused especially on the question of whether there are deprivation-specific psychological patterns (DSPs) that differ meaningfully from other forms of psychopathology. For this purpose, their main…
