“…As can be seen, there was a trend toward shorter reaction times in the lab/E-Prime condition, which is in line with previous findings that JavaScript produces slightly longer times both in an automated response system (Neath, Earle, Hallett, & Surprenant, 2011) and in human data (de Leeuw & Motz, 2015). At the same time, the smallest degree of variability was observed in the lab/browser condition, and the largest in the Web/ browser condition, implying that variance is not primarily due to software or technology, but rather is caused by situational and technical variation (which is greater on the Web than in the lab).…”

Reaction time effects in lab- versus Web-based research: Experimental evidence

Although Web-based research is now commonplace, it continues to spur skepticism from reviewers and editors, especially whenever reaction times are of primary interest. Such persistent preconceptions are based on arguments referring to increased variation, the limits of certain software and technologies, and a noteworthy lack of comparisons (between Web and lab) in fully randomized experiments. To provide a critical test, participants were randomly assigned to complete a lexical decision task either (a) in the lab using standard experimental software (E-Prime), (b) in the lab using a browser-based version (written in HTML and JavaScript), or (c) via the Web using the same browser-based version. The classical word frequency effect was typical in size and corresponded to a very large effect in all three conditions. There was no indication that the Web-or browser-based data collection was in any way inferior. In fact, if anything, a larger effect was obtained in the browser-based conditions than in the condition relying on standard experimental software. No differences between Web and lab (within the browser-based conditions) could be observed, thus disconfirming any substantial influence of increased technical or situational variation. In summary, the present experiment contradicts the still common preconception that reaction time effects of only a few hundred milliseconds cannot be detected in Web experiments.Keywords Web .

Today, Web-based research is common across the whole range of social and behavioral sciences. This trend is not surprising, given the well-documented advantages of Web-based research, especially the possibility to recruit large, heterogeneous (and more representative) samples in less time and with lower costs than in traditional lab-or paper/pencil-based research (for overviews, see

“…Neath and colleagues (Neath, Earle, Hallett, & Surprenant, 2011) used a photodiode connected to a solenoid to test different Apple systems with different presentation software (Psychophysics Toolbox, Java, JavaScript, or Flash). Upon stimulus onset, the photodiode detected changes in display luminosity and triggered a solenoid that pressed a key.…”

The Internet provides a convenient environment for data collection in psychology. Modern Web programming languages, such as JavaScript or Flash (ActionScript), facilitate complex experiments without the necessity of experimenter presence. Yet there is always a question of how much noise is added due to the differences between the setups used by participants and whether it is compensated for by increased ecological validity and larger sample sizes. This is especially a problem for experiments that measure response times (RTs), because they are more sensitive (and hence more susceptible to noise) than, for example, choices per se. We used a simple visual search task with different set sizes to compare laboratory performance with Web performance. The results suggest that although the locations (means) of RT distributions are different, other distribution parameters are not. Furthermore, the effect of experiment setting does not depend on set size, suggesting that task difficulty is not important in the choice of a data collection method. We also collected an additional online sample to investigate the effects of hardware and software diversity on the accuracy of RT data. We found that the high diversity of browsers, operating systems, and CPU performance may have a detrimental effect, though it can partly be compensated for by increased sample sizes and trial numbers. In sum, the findings show that Web-based experiments are an acceptable source of RT data, comparable to a common keyboard-based setup in the laboratory.

“…Existe a preocupação de diversos autores com relação à precisão da medida de tempo utilizando o computador com sistema operacional multitarefa como o Windows, em que a execução de outro programa pode interferir no desempenho do registro da fração de milissegundos da execução de uma tarefa de TR 4,[26][27][28] . Além disso, a qualidade dos acessórios empregados para resposta também apresenta diferenças significativas 29 .…”

Este estudo analisou a produção científica relacionada ao uso de softwares de tempo de reação (TR), identificando o mais utilizado e descrevendo a temática dos estudos que fizeram uso deste software, a partir de artigos publicados na base de dados ScienceDirect (de 2001 até 2013), por ser abrangente e cobrir as principais áreas de interesse no uso deste tipo de software. A partir das palavras "reaction time" e "computer ou software", identificou-se o software E-Prime ® como o mais utilizado, totalizando 11 artigos que foram selecionados para esta pesquisa. Os itens investigados foram: periódico, objetivo do estudo, amostra, área de aplicação ou especialidade, acessório utilizado para resposta, tipo de TR, descrição da tarefa e resultados. O periódico Appetite publicou dois artigos, as demais publicações ocorreram em periódicos distintos. Predominaram pesquisas com adultos saudáveis (n=5), com média de 57,6 participantes. Para registro da resposta, foi utilizado um acessório externo que acompanha o software. Quanto ao tema, foram identificados e apresentados resultados sobre análises da coordenação e planos motores (n=2), análises de transtornos relacionados ao uso de substâncias (n=2), transtornos da visão (n=1), análises no comportamento alimentar (n=2), o efeito da motivação sobre o desempenho no TR (n=1) e os transtornos da fala e da linguagem (n=2), além da avaliação dos distúrbios da atenção em Parkinsonianos (n=1). Os resultados demonstram a diversidade de aplicabilidade de estudos com tarefas de TR com o uso de apenas um software e a forte relação entre TR e medidas de saúde física e cognitiva.Palavras-chave: tempo de reação; software; transtornos das habilidades motoras. ABSTRACTThe study analyzed scientific production related to the use of reaction time software (RT), to identify the most used and describe the main issues of studies that have made use of this software published from 2001 to 2013 in the ScienceDirect electronic database, since this database is comprehensive and covers the main areas of interest with the use of this software. From the words "reaction time" and "computer or software", the E-Prime ® software was identified as the most used, totaling 11 articles, which were selected for the study. The items investigated were: journal, objective, sample, application area or specialty, accessory used to reply, RT type, task description and results. The Appetite journal published two articles; the other articles were published in different journals, with predominance of research with healthy adults (n=5) with 57.6 participants on average. To record response in the data collection, it was used an external accessory accompanying the software. In relation to the topic, the results of articles on the analyses of coordination and motor plans (n=2), analyses of disorders related to the use of substance (n=2), vision disorders (n=1), analyses of feeding behavior (n=2), effect of motivation on performance in RT (n=1), speech and language disorders (n=2), and evaluation of attention disorders in Parkins...
