Study Explores How Technology Can Help Prompt Positive Memories for People With Depression
Researchers have provided a crucial first step toward understanding how computing technology could be used to help people with depression remember happy memories.
Improving the recall of positive memories is a method used by clinical experts treating memory impairments of people with depression. This is, among other things, to help offset a bias toward negative thinking.
However, there are currently few technologies that have been designed specifically to support people experiencing memory impairments associated with depression.
A team of human-computer interaction researchers from the United Kingdom’s Lancaster University and Trinity College Dublin have, through in-depth interviews with experts in neuropsychology and cognitive behavioral therapies, found that most existing technologies related to supporting memory impairments are focused on “episodic” impairments, which are closely associated with conditions such as dementia.
The researchers explored three memory impairments in depression: negative bias, overgeneralization, and reduced positivity.
“Memory impairments in depression are fundamentally different,” says Corina Sas, PhD, a professor of digital health at Lancaster University and one of the researchers on the project. “Their effect is not felt through the loss of episodic memories but rather difficulties in retrieving these memories among memories of general events and periods within their lifetime.
“People living with depression not only benefit less from the types of cues usually explored in existing memory technology research, but such cues can also be counterproductive.”
The researchers identified several areas of opportunity for where technology could help. These include the following:
“Novel technologies that can adapt the retrieval of positive memories to the current emotional state of the user will be important,” Sas says.
“We can imagine technologies that prompt people to identify and retrieve positive memories as counterexamples for when people are ruminating over negative thoughts. This can help support a more balanced perspective on life and help increase the accessibility and value of positive memories.”
The study aims to inform specialists working in the “Human-Computer Interaction” field about the limitations of existing memory technologies and factors to consider when designing new technologies to help people with depression. “These methods could be integrated into a range of different mental health technologies,” says Gavin Doherty, DPhil, an associate professor at Trinity College Dublin, and cofounder of SilverCloud Health—a health technology company.
