The impact of intelligent decision support systems on intellectual Task Success: an empirical investigation
Decision Support Systems, 2006Co-Authors: Éliane M.f. MoreauAbstract:The purpose of this research was to analyze the impacts of intelligent decision support systems (IDSS) on intellectual Task Success. Data were gathered from 180 users in three Canadian firms. A structural equation analysis was performed to test a causal model. The main findings of this study are that intellectual workers who are satisfied with IDSS user-friendliness perceive their Tasks as being more enriching and the systems themselves as being more useful. In addition, if these users perceive a good job outcome with IDSS, then it may lead to the Successful performance of the user's Task.

Performance at a Precognitive Remote Viewing Task, with and without Ganzfeld Stimulation: Three Experiments
'Rhine Research Centre', 2020Co-Authors: Roe Chris, Cooper Callum, Hickinbotham L, Hodrien Andrew, Kirkwood Laurrie, Martin HannahAbstract:Recent research by the lead author has sought to incorporate ganzfeld stimulation as part of a remote viewing protocol. An initial exploratory experiment (Roe & Flint, 2007) suggested that novice participants can Successfully describe a randomly selected target location while in the ganzfeld but did not make a direct comparison with performance in a waking state. This paper describes a series of three subsequent experiments that compared performance at a remote viewing Task in a waking condition with a ganzfeld stimulation condition using a counterbalanced repeated measures design. There were only minor variations in design across the three experiments to enable combination of Data in a summary analysis. In total, 110 participants produced 43 hits in the ganzfeld stimulation condition (39.1%), giving a statistically significant positive deviation from chance expectation (sum of ranks = 225, p = .000012), whereas in the waking RV condition they achieved 30 hits (27.3%) which is marginally better than chance expectation (sum of ranks = 253, p = .034). The difference in z scores for target ratings in the two conditions approaches significance (t[39] = 1.865, p = .065). In experiment 1, individual difference measures identified as predictors of psi performance were unrelated to target ratings. Participants completed Pekala’s (1991) Phenomenology of Consciousness Inventory (PCI) in order to gauge their responsiveness to the ganzfeld protocol and of the 12 sub-dimensions tested, ganzfeld performance correlated significantly with greater absorption in their subjective experience, lower physiological arousal and less internal dialogue. In experiments 2 and 3 individual differences measure were replaced by measures of transliminality, openness to experience, and dissociative experiences, but these were also unrelated to Task Success. Data from experiment 2 did not confirm findings using the PCI from experiment 1, though a significant association was found with the time sense dimension. In experiment 3 no PCI dimensions were correlated with Task performance, a pattern which was confirmed when Data was combined across all three experiments

Discount Approaches to Building an Online Study
Beyond the Usability Lab, 2010Co-Authors: Bill Albert, Tom Tullis, Donna TedescoAbstract:This chapter provides a set of step-by-step directions for building a personal online usability study using standard online survey tools and a little bit of HTML and JavaScript. Techniques that allow users to collect Task Success Data, Task times, Task-based ratings and comments, and postTask ratings and comments, including ratings using the system usability scale (SUS) are described in the chapter. Online survey tools can be used to present Tasks to participants and collect their answers, allowing capturing Task Success Data. One can easily add rating scales to the online survey to collect Task-based ratings, such as how easy or difficult each Task was. One can also use conditional logic in an online survey to collect comments or explanations related to the Tasks (e.g., why they gave up on a Task or rated it as being very difficult). Using certain online survey tools, variables can be added to each Task that allows capturing Task time. Certain online survey tools also allow randomizing the order of the Tasks. With a little bit of HTML and JavaScript, the Task window (containing the survey) and the main window (containing the site or prototype being evaluated) can be positioned so that the participant can work with both of them easily. Finally, with a little more HTML and JavaScript, participants can be randomly assigned to different conditions or prototypes.
