Context, then, is essential to understanding human decision making, but short of following someone around 24\/7, accurately capturing this context has always been difficult. Until now.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The big data being regularly captured on all of us, through online services, phones, wearables and Internet of Things devices, is providing psychological scientists with the tools to indeed effectively follow around their subjects with relative ease. And this new ability to observe people in their natural habitats is telling us some interesting things.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In my research group, we have been using big data approaches to understand human long-term memory. Memory is particularly difficult to study in the laboratory because performance depends to a large extent on the lifetime of experiences people have before they enter.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">German psychologist <\/span><a href=\"https:\/\/www.britannica.com\/biography\/Hermann-Ebbinghaus\"><span style=\"font-weight: 400;\">Hermann Ebbinghaus<\/span><\/a><span style=\"font-weight: 400;\"> (1859-1909) \u2013 the father of memory science \u2013 was well aware of the problem. In testing people\u2019s memory, he needed something that would be unaffected by a person\u2019s past experience and prior associations.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">He came up with the idea of using nonsense syllables \u2013 like JOF and VEP. But it doesn\u2019t really work. People are ingenious at turning nonsense syllables into acronyms or forming other associations.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">These days, we use a range of stimuli \u2013 words, pictures, movie clips. These stimuli are more valid than nonsense syllables, but generalising from the laboratory to the real world is still very difficult. The laboratory is just too different from the circumstances of normal memory use.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">So, in our research we started with a simple question. How well can people remember where they were at a given time?<\/span><\/p>\n<p><span style=\"font-weight: 400;\">We gave people a series of dates and times and had them select markers on a map to indicate where they had been. We used the record of locations collected by people\u2019s phones to score whether they were correct. We found that overall, people are right about <\/span><a href=\"https:\/\/journals.sagepub.com\/doi\/full\/10.1177\/0956797620980752\"><span style=\"font-weight: 400;\">two thirds of the time<\/span><\/a><span style=\"font-weight: 400;\">. That\u2019s useful to know if you are judging the accuracy of eyewitness testimony or you are involved in contact tracing.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">However, we can go much further \u2013 we can take samples of people\u2019s sound environments, record their movements, ask them how they are feeling, see who they have been texting and what they have been reading online.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The aim is to build up a comprehensive picture of their experiences so we can determine how people remember different kinds of information and which factors influence their ability to remember.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">We now know that when people move \u2013 as measured by the accelerometer in people\u2019s phones \u2013 it is a surprisingly good signal to us of when people believe an event has finished, that we can then test their memory on.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">We also know that everyday emotions (as distinct from the intense emotions that people relate to important events and experiences) seem to influence people\u2019s memories surprisingly little.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The use of big data is opening entirely new vistas in memory research, but I think this will be the tip of the iceberg. Big personal data will have a similar impact across all of psychological science, but only if people continue to be prepared to provide it.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Rocks are different from people in another important way. If I measure the chemical composition of a rock, pick it up a few times and watch how it falls, then share this data with friends and colleagues, the rock doesn\u2019t care.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">People do care, however, and with good reason. Increasingly, it feels like our personal information on the web is being used against us \u2013 from insidious advertising to cyber-attacks.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">As cyber security consultant Troy Hunt pointed out on the <\/span><a href=\"https:\/\/psychologicalsciences.unimelb.edu.au\/engage\/75th-anniversary\/podcasts\"><span style=\"font-weight: 400;\">PsychTalks<\/span><\/a><span style=\"font-weight: 400;\"> podcast:<\/span><\/p>\n<blockquote><p><i><span style=\"font-weight: 400;\">\u201cBusinesses are increasingly turning to data aggregators. These \u2018middle men\u2019 are capable of analysing personal data across multiple sources to build up a picture of who a person is and what their habits and preferences are. On the shadier end, there have been numerous services out there that have simply taken data breaches and sold the data.\u201d<\/span><\/i><\/p><\/blockquote>\n<p><span style=\"font-weight: 400;\">In this environment, where we give away so much of our data for free, it is challenging for people to take control of their own data and then make it available to others, whether for researchers or other interests. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">However, <\/span><a href=\"https:\/\/www.cambridge.org\/core\/journals\/data-and-policy\/article\/emerging-health-data-platforms-from-individual-control-to-collective-data-governance\/C2FABA49744B674D157DC5E09E15DDCD\"><span style=\"font-weight: 400;\">services are emerging that are allowing people to \u201cown\u201d their data and potentially charge for it<\/span><\/a><span style=\"font-weight: 400;\">. Researchers need to adjust to the idea that they don\u2019t own the data they collect on individuals, and cannot pass it on to others.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Governments are already making substantial changes in privacy law. <\/span><a href=\"https:\/\/gdpr.eu\/what-is-gdpr\/#:~:text=The%20General%20Data%20Protection%20Regulation,to%20people%20in%20the%20EU.\"><span style=\"font-weight: 400;\">The General Data Protection Regulation<\/span><\/a><span style=\"font-weight: 400;\"> (GDPR) in the EU and the <\/span><a href=\"https:\/\/leginfo.legislature.ca.gov\/faces\/codes_displayText.xhtml?division=3.&amp;part=4.&amp;lawCode=CIV&amp;title=1.81.5\"><span style=\"font-weight: 400;\">California Consumer Privacy Act<\/span><\/a><span style=\"font-weight: 400;\"> (CCPA) are harbingers of what is to come.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Australia is currently going through privacy law reform and we can expect these processes to be ongoing as we transition from the wild west of data governance that exists in many contexts today into a more thoughtful and sustainable approach to data usage.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">What this means is that, if we are serious about making substantial progress in psychology, we are going to have to renegotiate our contract with our participants. The old rules won\u2019t work with such sensitive data.<\/span><\/p>\n<p><strong><em>This article was first published on <\/em><a href=\"https:\/\/pursuit.unimelb.edu.au\/\">Pursuit<\/a><em>.
