Social Foundations of Self I: Play and Game

Social Foundations of Self I: Play and Game

The development of self in children is deeply rooted in social interactions, mainly through stages of play and structured games. These stages, outlined by sociologist George Herbert Mead, illustrate how children progressively learn to understand and adopt social roles, forming a cohesive sense of self.The Play Stage: Imitation and Simple Role-TakingIn the early years of childhood, the play stage is characterized by imitative behavior, where children engage in role-playing based on familiar...

Sustainable Development

Sustainable Development

As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

Biodiversity and Human Values

Biodiversity and Human Values

Human civilization relies on biodiversity in many ways. Sudden changes in species biodiversity result in environmental changes that can modify weather patterns and therefore human civilizations.

Evolutionary Psychology

Evolutionary Psychology

Evolutionary psychology explores the origins of human behavior and mental processes by framing them within the context of natural selection, a theory famously propounded by Charles Darwin. This field asserts that many behaviors common across human societies — ranging from instinctive fear reactions to complex social interactions — arose as evolutionary adaptations. These adaptations enhanced the survival and reproductive success of our ancestors, thereby becoming embedded in the human psyche...

The Scope of Physics

The Scope of Physics

Physics is concerned with the interactions of energy, matter, space, and time, in order to discover the underlying mechanisms that underpin all phenomena. The word "physics" comes from the Greek word "phúsis", which means nature. Physics seeks to comprehend the natural world around us at its most fundamental level. It emphasizes the use of quantitative laws to do this, which could be valuable in other fields that want to push the performance boundaries of present technologies.

Functionalism

Functionalism

William James, John Dewey, and Charles Sanders Peirce were instrumental in founding functional psychology, which draws heavily from Darwin's theory of evolution by natural selection. This theory suggests that individual traits, including behaviors, are adapted to their environments through natural selection. At the heart of functionalism is the concept of adaptation, meaning that a trait enhances an individual's chances of survival and reproduction.
James envisioned psychology's role as...

Summary

Canonical discourse tasks are valuable for cognitive-communication disorders research but need a framework for appropriate use. A fit-for-purpose approach ensures tasks align with specific populations and clinical goals.

Area of Science:

Cognitive-Communication Disorders
Discourse Analysis
Translational Research

Background:

Discourse analysis is crucial for assessing and treating neurogenic and cognitive-communication disorders.
Canonical discourse elicitation tasks (e.g., Cinderella retell) have historically yielded rich language samples for research.
A tension exists between the value of canonical tasks and their limitations in capturing all relevant discourse constructs.

Purpose of the Study:

To examine the utility and limitations of canonical discourse tasks in cognitive-communication disorders.
To propose a principled framework for selecting and adapting discourse tasks.
To advocate for a fit-for-purpose discourse science integrating various methods and technologies.

Main Methods:

Narrative review drawing on translational research experience.
Analysis of discussions from the International Cognitive-Communication Disorders Conference (ICCDC).
Examination of the historical role and future application of canonical discourse tasks.

Main Results:

Canonical tasks offer continuity and comparability but may not suit all populations or clinical needs.
A framework is needed to guide decisions on retaining, adapting, or developing new discourse tasks.
A fit-for-purpose discourse science emphasizes appropriateness, robustness, and alignment with research/clinical goals.

Conclusions:

The field requires a principled approach to discourse task selection, not just new tasks.
Integrating psychometric rigor, participatory design, and technology is essential for robust discourse science.
Practical guidance is provided for choosing tasks in research and clinical practice.
