Biography

I graduated from the University of Tasmania with a B.Sc. in Physics and Psychology in 1983 and a 1^st Class Honours in Psychology in 1984. I completed a PhD Queen’s University in Canada with Doug Mewhort in 1990 as a Commonwealth Postgraduate Fellow, and was a Postdoctoral Fellow with Roger Ratcliff at Northwestern University in Chicago in 1991. In 1992 I returned to Australia as a lecturer at University of Newcastle and from 2004-2006 I was Deputy Head and then Head of its School of Psychology. Subsequently became a full Professor and founded the Newcastle Cognition Laboratory (NewCL.org). In 2011 I was awarded a Professorial Fellowship by the ARC. In 2012 I was elected to the Australian Academy of Social Sciences and served as Vice-President of the Society for Mathematical Psychology 2014-2016 and President of the Australasian Experimental Psychology Society in 2017. In 2015 I took up a research chair at University of Tasmania and founded the Tasmanian Cognition Laboratory (TasCL.org).

Current projects

Memory for when something happened (episodic memory) is critical to performance across the range of human activity. At the moment, there is no theory that is sufficiently complete and quantitatively rigorous to allow one to assess memory capacities at the level of individuals. A five-year project with a national and international research team beginning in 2015 will develop a comprehensive theory of memory to fill this gap, enabling understanding of the causes of forgetting in different tasks and at different stages of development. A second recent project aims to extend state-of-the art quantitative psychological models of simple choice tasks to decision making with complex stimuli in complex environments. These new formal models will provide a comprehensive account of behaviour, including the choices that are made, how long it takes to make them, and how choices and choice times vary within and between decision makers. The models will explain how people adapt to changes in task demands when dealing with multiple stimuli or performing multiple tasks concurrently under time pressure. The project will provide the strategic basic research that is needed to extend psychological models of choice to complex 'real-world' tasks, such air traffic control and maritime surveillance.

Grants & Funding

Andrew has held 10 ARC Discovery projects during his career with funding totalling over $2.7m. In these projects Andrew has been part of research teams that have developed a new perspective on the law of practice, the relationship between speed-skill and practice, a unified theory of performance in absolute identification tasks, new approaches to understanding recognition memory, choice models for learning and memory and integrated models of the neuroscience of rapid decisions and in ongoing work a unified theory of episodic memory and applications of comprehensive models of simple choice to complex real-world decisions. This emphasis on real world decision making has led to recent gratns with DST Group and CSIRO’s Data 61.

Automation, Trust, and Workload: UTAS / CSIRO / UoSA Collaborative Research Project (2017 - 2019)$212,982

Description: Automation, and autonomous systems, are playing an increasing role in every-day life. Whereas the previous generation of autonomous technology had its impact largely in industrial spaces, (e.g. automotive factory robots), current advances are bringing such systems into the homes, workplaces, and automobiles of todays citizens. A key factor here is the increased proximity to human operators and bystanders. This project aims to develop a useful model for making predictive analyses based on these three factors, Automation, Trust, and Workload.The work will focus on both traditional methods of workload estimation (i.e. subjective questionnaire) and novel methodology using psychophysiological methodology to measure workload in a way that does not interrupt critical task flow, as is the case with traditional methodology. Such methodologies include, but are not limited to: Pupillometry (using fluctuations in pupil diameter to indicate cognitive load, e.g. (Duenser, Lochner, Engelke, & Rozado, 2015); electro-dermal activity (using skin conductivity to infer cognitive load, e.g. (Lochner, Duenser, Lutzhoft, Brooks, & Rozado, 2016); IR camera-based pulse detection (using video imagery to detect pulse rate, e.g. (Stemberger, Allison, & Schnell, 2010). It is our goal to develop and validate a hybrid methodology for assessing workload in critical task environments, where standard interruptive measurement techniques are not appropriate due to various considerations including safety, efficiency, and efficacy. This framework is not limited to assessing physical automation (e.g. self driving cars, autonomous robotics), but also includes automation within a user-experience framework, considering automated web-based information systems.The second key factor (the first being the level of autonomy) in the model under development is the individuals level of trust in the automated system. Recent research on human interactions with autonomous systems (e.g., Freedy, DeVisser, Weltman, & Coeyman, 2007; Lee & See, 2004) indicates that the level of trust in the system affects the success of the interaction on a number of levels, and should therefore be taken into account as a major factor in the design process. The current project contributors believe that a relation between trust, autonomy, and workload is intrinsic to the human-machine system, and that the development of a model surrounding these influences will inform the successful future development of such systems. This research sits at the nexus of three academic disciplines, namely computer science, psychology, and engineering. The development of systems that operate with variable levels of human engagement, requires an explicit understanding of the human capacity for work, the strengths and limitations of the technology, and a way to predict when errors will occur. The proposed project structure will support this multidisciplinary work by establishing the appropriate interdepartmental connections.

Providing Automation with Situational Awareness of Operator Workload (2017)$97,159

Description: Human operators - particularly in demanding Defence jobs - experience workload levels varying from light or none to complete overload. These workload fluctuations can be associated with sub-optimal performance, which can lead to poor outcomes or even mission failure. Automation, in the form of artificial intelligence that can take over routine tasks and/or recommend smart options, promises to alleviate some of these concerns but raises its own problem. Under-load can cause mind-wandering, sometimes called "automation neglect", leaving the operator ill prepared for emergencies, and automated recommenders, lacking the situational awareness of human assistants, can cause failures by intruding at critical times or providing options that overload the operator's capacity. We aim to develop a hardware and software package for monitoring and predicting operator engagement and workload in real time.

Modelling human decision making in complex environments (2016 - 2018)$635,000

Description: The project aims to extend state-of-the art quantitative psychological models of simple choice tasks to decisionmaking with complex stimuli in complex environments. These new formal models will provide a comprehensiveaccount of behaviour, including the choices that are made, how long it takes to make them, and how choices andchoice times vary within and between decision makers. The models will explain how people adapt to changes intask demands when dealing with multiple stimuli or performing multiple tasks concurrently under time pressure.The project will provide the strategic basic research that is needed to extend psychological models of choice tocomplex real-world tasks, such air traffic control and maritime surveillance.

Developing a Unified Theory of Episodic Memory (2015 - 2019)$757,800

Description: This proposal aims to develop a model of episodic memory and to apply the model to both adult and child development data. Unlike current approaches, the model will address multiple memory tasks including item recognition, associative recognition, source recognition and cued recall and will also address reaction timedata, allowing different sources of interference causing forgetting in adults to be identified. By addressing both encoding and retrieval processes, the model can assess how changes in different sources of interference modulate performance through the trajectory of early development. Hierarchical Bayesian estimation will enable a simultaneous account of multiple tasks and support future deployment in appliedcontexts.

Choice Models for Learning and Memory (2011 - 2015)$544,155

Description: Life is filled with well familiar choices that are made quickly and with sensitivity to the decision context, suchas ones overall level of knowledge and the consequences of the decisions. This project will develop and testquantitative models, using Bayesian estimation and model selection, of a) learning to transition from taskmastery (i.e., effortful, fairly accurate but slower choices) to fluent (i.e., accurate, rapid and effortless)performance, and b) the accuracy, speed and confidence of decisions about recognition memory (i.e.,whether an item was previously encountered in a particular context) as a function of the probability andsimilarity of choices and the likely strength and sources of information provided by memory.
