There are numerous guides on Web design but for the most part, these are based on designers' intuition and common sense Ð with little theoretical or experimental validation. A major problem is that there is a general lack of cognitive guidelines for Web design. Of the few available theoretical guidelines for designing hypermedia documents, very little experimental research is available that tes...

This paper discusses the possibility of using embodied Ambient Displays for presenting information in a public setting.

Throughout four weeks of alternating traditional visual Ambient Displays and Nabaztag testing, differences and commonalities in terms of perceived usability and like...

Decision Support Systems Abstract Process modeling grammars are used to create models of business processes. In this paper, we discuss how different routing symbol designs affect an individual’s ability to comprehend process models. We conduct an experiment with 154 students to ascertain which visual design principles influence process model comprehension. Our findings suggest that design princ...

this study examined the differences among high, mid and low ambiguity tolerance groups in their reading comprehension ability and their metacognitive awareness of reading strategies. to this end, 123 first-year college students majoring in engineering with an age range of 19-25 were stratified into three groups of high, mid and low ambiguity tolerance to participate in the study. they took part...

OBJECTIVES Numeracy, the ability to process basic mathematical concepts, may affect responses to graphical displays of health risk information. Displays of probabilistic risk information using grouped dots are easier to understand than displays using dispersed dots. However, dispersed dots may better convey the randomness with which health threats occur, so increasing perceived susceptibility. ...

BACKGROUND Although randomized clinical trials are currently the standard for the evaluation of new therapeutic strategies, little attention has been paid to the viewpoint of the patients recruited to these trials. OBJECTIVES To examine the perspective of the Israeli patient cohort who participated in the Fourth International Study of Infarct Survival, a randomized trial in acute myocardial i...

Reading motivation has been viewed as a multifaceted construct with multiple constituents. Our investigation of motivational multiplicity expanded on previous literature by including motivation constructs (interest, perceived control, collaboration, involvement, and efficacy), text genres, specific versus general contexts, and the self-versus other evidence sources about motivation.
