Data storage. There are two main parts of the data storage that I’d like to discuss. First off, there’s the within-experiment data storage and its API. jsPsych automatically stores all data related to previous trials and allows you to fairly easily recall all this data (even from several trials back).
The plan for week 2. Week 2 is our first week of actual content. The reading in week 2 is designed to give you a brief intro to why people collect data online, advantages and shortcomings, to lay out some of the options in terms of how to build experiments and what platforms people use to connect with participants, and to give you a feel for what online experiments can look like (focussing on ...

Mar 24, 2015 · In many cases, the quality of online data appears to match that collected in lab research. Generally-speaking, online participants tend to be more representative of the population at large than those recruited for lab based research. There are, though, some important caveats, when it comes to collecting data online.

Nov 18, 2020 · Dogmatic individuals are reluctant to seek out new information to refine their views, often skewing political, scientific, and religious discourse in the process. The cognitive drivers of this reluctance are poorly understood. Here, we isolate an influence of uncertainty on information search using a low-level perceptual decision-making task. We show that people with dogmatic views are both ...

Of course, more detailed data is available to export and analyze, if desired. Data displayed in iMotions showing the time-to-first-fixation (TTFF), the time spent in seconds looking at the AOI (which is only shown to one decimal point in the image above), and the ratio of participants who viewed the AOI.
Online methods potentially allow rapid and low-effort collection of large samples, and are particularly useful in situations where face-to-face data collection is not possible (e.g. during a pandemic); however, building and running these experiments poses challenges that differ from lab-based methods.

My name is David John Baker, I'm an interdisciplinary researcher and educator. I just finished up working as a Lead Instructor of Data Science at Flatiron School in London, England where I combined my love of research, programming, and teaching to help students succeed as they learn the skills they need in order to begin a new career. jsPsych is a JavaScript library for running behavioral experiments in a web browser. The library provides a flexible framework for building a wide range of laboratory-like experiments that can be run online. To use jsPsych, you provide a description of the experiment in the form of a timeline. jsPsych handles things like determining which trial to run next, storing data, and randomization. jsPsych uses plugins to define what to do at each point on the timeline.

Table S1 in the Supplemental Material available online details the pro-cedure used to generate the stimuli, and Figure 1a shows examples of the resulting category structures. Our online data accurately reproduced the original results and allowed for a novel assessment of demographic variables such as age and gender. In parallel, we also measured the objective timing accuracy of the jsPsych interface by using specialized hardware and software, showing a constant 60-ms delay for RTs and a 0-ms delay for IKIs across ...

These experiments were implemented using jsPsych and custom javascript functions. We used the.webm format as it is a HTML5-compliant video format to ensure fast loading times for the web browsers. The challenge images used to generate the stimuli videos are converted to 256 256 to ensure consistent sized images across the trials. Sprouse gives a long list of limitations of online data collection at the end of the paper, including technical limitations around audio, reaction times, randomisation. The technology has obviously moved on since Sprouse wrote the paper, and jsPsych is going to handle all these problems for us.
