It has been approximately 100 years since the very first formal experimental evaluations of statistical charts were conducted. In that time, technological changes have impacted both our charts and our testing methods, resulting in a dizzying array of charts, many different taxonomies to classify graphics, and several different philosophical approaches to testing the efficacy of charts and graphs experimentally. Once rare, charts and graphical displays are now everywhere—but do they help us understand? In this article we review the history of graphical testing across disciplines, discuss different direct approaches to testing graphics, and contrast direct tests with visual inference, which requires that the viewer determine both the question and the answer. Examining the past 100 years of graphical testing, we summarize best practices for creating effective graphics and discuss what the future holds for graphics and empirical testing of interactive statistical visualizations.

Hard To Reach Populations

People with dementia may miss out on the benefits of using technology, because they often find it difficult to use. Usability testing is one method to identify barriers and areas for improvement in technology. Unfortunately, usability testing is often not conducted with people with dementia, independent of their caregivers. Difficulty recruiting local participants with dementia who regularly use technology further compounds the problem. Remote methods have been proposed as one approach to recruiting hard-to-reach populations. Currently, it is unclear how to effectively conduct remote summative usability testing with people with dementia. We recruited 15 participants. Five took part in the pilot study and 10 participated in the main study. We identify best practices and make suggestions for remote summative usability tests with people who have mild to moderate dementia, independent of caregivers. We discuss our findings in three sections: (1) logistics for planning remote summative usability testing, (2) approaches for conducting remote summative usability testing, including modifications of research methods, and (3) considerations when evaluating findings from remote summative usability sessions. We also present modified usability testing methods we developed to meet the unique needs of users with mild to moderate dementia, and summarize lessons learned and new directions for research on this topic.

AbstractSince the discovery of an oncogenic tropomyosin-receptor kinase (TRK) fusion protein in the early 1980s, our understanding of neurotrophic tropomyosin-receptor kinase (NTRK) fusions, their unique patterns of frequency in different tumor types, and methods to detect them have grown in scope and depth. Identification of these molecular alterations in the management of patients with cancer has become increasingly important with the emergence of histology-agnostic, US Food and Drug Administration-approved, effective TRK protein inhibitors. Herein, we review the biology of TRK in normal and malignant tissues, as well as the prevalence and enrichment patterns of these fusions across tumor types. Testing methods currently used to identify NTRK1–3 fusions will be reviewed in detail, with attention to newer assays including RNA-based next-generation sequencing. Recently proposed algorithms for NTRK fusion testing will be compared, and practical insights provided on how testing can best be implemented and communicated within the multidisciplinary healthcare team.

This chapter explores the concepts and challenges behind testing Web applications, and explores the latest testing techniques and best practices. As our reliance on the Internet grows, the quality and reliability of online resources become critical. Unfortunately, significant research shows that the current approaches to modern Web development are woefully inadequate. It is important that there are processes in place and best practices established to ensure that the development of Web applications can take place with an assurance of quality. In addition to offering an initiation to some of the modern testing methods and tools, the authors hope to motivate readers to consider testing as a multi-purpose tool to be used throughout all stages of development.

Social Communication Disorders

Purpose The purpose of this article is to explore and describe the approaches and specific assessment tools that speech-language pathologists are currently using to assess social communication disorders (SCDs) in children, in relation to current best practices. Method Ninety-four speech-language pathologists completed an online survey asking them to identify which of the following approaches they use to assess children with SCD: parent/teacher report, naturalistic observation, formal assessment, language sample analysis, interviews, semistructured tasks, and peer/self-report. Participants were also asked to identify specific assessment tools they use within each approach. Results Participants most commonly assess SCDs by combining interviews, naturalistic observation, language sampling, parent/teacher report, and formal assessment. Semistructured tasks and peer/self-report tools were less frequently utilized. Several established parent/teacher report and formal assessment tools were commonly identified for assessing SCDs. Most participants use an informal approach for interviews, language sampling, and naturalistic observations in their SCD assessment process. Conclusions Generally, participants follow best practices for assessing SCDs by combining several different approaches. Some considerations for future assessment are identified, including the use of established protocols in the place of informal approaches in order to make the assessment of SCDs more systematic. Future directions for research are discussed.

Provision Of Services

According to the 2010 U.S. Census, over 20% of Americans speak a language other than English in the home, with Spanish, Chinese, and French being the languages most commonly spoken, aside from English. However, few augmentative and alternative communication (AAC) systems offer multilingual support for individuals with limited functional speech. There has been much discussion in the AAC community about best practices in AAC system design and intervention strategies, but limited resources exist to help us provide robust, flexible systems for users who speak languages other than English. We must provide services that take into consideration the unique needs of culturally and linguistically diverse users of AAC and help them reach their full communication potential. This article outlines basic guidelines for best practices in AAC design and selection, and presents practical applications of these best practices to multilingual/multicultural clients.

Communication Needs

People with ASD often need to access AAC in situations where a tabletop digital device is not practical. Recent advancements have made more powerful, portable, and affordable communication technologies available to these individuals. Proloquo2Go is a new portable augmentative and alternative communication system that runs on an iPhone or iPod touch and can be used to meet the diverse needs of individuals with autism spectrum disorders (ASD) who are ambulatory and have difficulty using speech to meet their full daily communication needs. This article examines Proloquo2Go in light of the best practices in AAC for individuals with ASD such as symbols, visual supports, voice output, and inclusion.

And Function

The search for best practices in hearing aid fittings and aural rehabilitation has generally used the audiogram and function stemming from peripheral sensitivity. In recent years, however, we have learned that individuals respond differently to various hearing aid and aural rehabilitation techniques based on cognitive abilities. In this paper, we review basic concepts of working memory and the literature driving our knowledge in newer concepts of hearing aid fitting and aural rehabilitation.
