BACKGROUND Patient-reported outcomes (PROs) from social media use in chronic disease management continue to emerge. While many published articles suggest the potential for social media is positive, there is a lack of robust examination into mediating mechanisms that might help explain social media's therapeutic value. This study presents findings from a global online survey of people with chron...

The goal of the present study was to investigate event-related potential (ERP) responses to Dutch negative and positive polarity adverbs of degree presented in licensed and unlicensed contexts with negative and affirmative particles directly preceding the polarity item. To control for effects of the processing of negation as such, neutral adverbs were also presented in negative and affirmative ...

This paper investigates an approach to human-computer interaction – actability theory – that emphasises human-via-computer-to-human interaction. This social action approach to HCI is confronted with affordance theory by Gibson; an ecological theory of perception. The notion of affordance is compared and related to actability. Different IT usage situations described in actability theory are crit...

User experience remains a crucial consideration when assessing the successfulness of information visualization systems. The theory of affordances provides a robust framework for user experience design. In this article, we demonstrate a design case that employs an affordance-based framework and evaluate the information visualization display design. SolarWheels is an interactive information visua...

Extensive research has suggested that simply viewing an object can automatically prime compatible actions for object manipulation, known as affordances. Here we explored the generation of covert motor plans afforded by real objects with precision ('pinchable') or whole-hand/power ('graspable') grip significance under different types of vision. In Experiment 1, participants viewed real object pr...

Human behavior is an underlying cause for many of the ecological crises faced in the 21st century, and there is no escaping from the fact that widespread behavior change is necessary for socio-ecological systems to take a sustainable turn. Whilst making people and communities behave sustainably is a fundamental objective for environmental policy, behavior change interventions and policies are o...

The interaction between humans and portable technologies, as a part of the broader problem of technology use in Human-Computer Interaction, has received considerable research attention and has been approached from diverse angles. The concept of affordance, drawn from ideas in the psychology of perception, is one of these angles. Unfortunately, most of these theories of perception which premise ...

Most human-made objects are designed with a particular function and user in mind. This means that most have well-defined affordances. An important question remains unanswered concerns the perception of affordances were not created for specific purpose. Investigating such would provide insight into how perceived via exploratory activity. In addition, comparison ambiguous across vision haptics of...
