Presenting personalised health risk information can support lifestyle decisions and help patients make informed choices about treatments. The way such information is presented can influence how well it is understood, and supplementary graphical representations have been shown to be helpful. However, there are little data on longer term recall of risk-related messages presented graphically and on the attention paid to graphics by those trying to interpret risk-related messages. This article draws on two studies in the United Kingdom of risk information recall. In study 1, participants aged 40–65 (N = 570) were given hypothetical personal cardiac risk information via a website, either ...

This study investigated the effects of reading a science text illustrated by either a labeled or unlabeled picture. Both the online process of reading the text and the offline conceptual learning from the text were examined. Eye-tracking methodology was used to trace text and picture processing through indexes of first- and second-pass reading or inspection. Fifty-six sixth graders were randomly assigned to one of three reading conditions (text with a labeled illustration, text with an unlabeled illustration, or text only) in a pretest, immediate posttest, and delayed posttest design. Results showedno differences for factual knowledge as a function of reading ...

Pictorials can aid in communicating warning information, but viewers may not always correctly comprehend them. Two experiments focused on whether the use of relevant highlighting could benefit pictorial comprehension. A set of warning-related pictorials were manipulated according to three-color highlighting conditions: highlighting areas more relevant to correct comprehension, highlighting areas less relevant to comprehension, and no highlighting. Participants were asked to describe the purpose and meaning of each pictorial presented to them. The findings from both experiments indicate that comprehension of warning pictorials is higher for the relevant highlighting condition than the other two conditions. The highlighting of less relevant ...

Background: Processing Web-based health information can be difficult, especially for people with low health literacy. Presenting health information in an audiovisual format, such as animation, is expected to improve understanding among low health literate audiences. Objective: The aim of this paper is to investigate what features of spoken health animations improve information recall and attitudes and whether there are differences between health literacy groups. Methods: We conducted an online experiment among 231 participants aged 55 years or older with either low or high health literacy. A 2 (spoken vs written text) x 2 (illustration vs animation) design was used. Participants were randomly exposed ...

Although the use of illustrations is often recommended for audiences with limited health literacy, it is unclear how health literacy impacts the use of different online formats. The aim of this paper is therefore to investigate how health literacy influences attention to text and illustrations in online health information, and whether such attention is related to recall of information. Sixty-one participants were exposed to either text-only or text-illustrated information. Using eye tracking, we recorded attention patterns on a health webpage after which recall of information was assessed. Results showed that health literacy influenced the attention–recall relationship. For people with limited ...

It is often recommended that health information should be simplified for people with low health literacy. However, little is known about whether messages adapted to low health literacy audiences are also effective for people with high health literacy, or whether simple messages are counterproductive in this group. Using a two (illustrated vs. text-only) by two (nondifficult vs. difficult text) between-subjects design, we test whether older adults with low (n = 279) versus high health literacy (n = 280) respond differently to colorectal cancer screening messages. Results showed that both health literacy groups recalled information best when the text was nondifficult. ...

Gerontolinguistic obtains a growing importance with the increase of elderly users due to Demographic Change. Since acceptance and ease of use of supportive systems for elderly, such as "E-Nursing-Assistants", are highly dependent on the age suitable design of readable instructions, an age-appropriate linguistic concept is of high value for usability. There has been only little research on the relevance of foreign words, signal words, textual arrangement, optical accentuation of key terms and temporal iconicity concerning older users. Thus, an efficient design of age suitable manual instructions within a medical context still remains to be done. The objective of this research ...

A neglected issue in the literature on visual-word recognition is the careful examination of parameters such as font, size, or interletter/interword spacing on reading times. Here we analysed whether serifs (i.e., the small features at the end of strokes) play a role in lexical access. Traditionally, serif fonts have been considered easier to read than sans serif fonts, but prior empirical evidence is scarce and inconclusive. Here we conducted a lexical decision experiment (i.e., a word/nonword discrimination task) in which we compared words from the same family (Lucida) either with a serif font or with a sans serif font*in both ...
