In a series of studies, Elizabeth Cowley (University of Sydney) examines repeat gambling in the face of loss. She finds that people often engage in too much positive thinking, selectively focusing on one win among hundreds of losses when they think back on the overall experience.
“When we want to justify engaging in an activity which could potentially be irresponsible – like gambling – we may need to distort our memory of the past to rationalize the decision,” Cowley explains. “People who have frequently spent more money than planned on gambling edit their memories of the past in order to justify gambling again.”
For example, Cowley had participants in one study play a computer game in which they could win credits with the financial equivalent of one cent per credit. Each participant played the game 300 times. Everyone experienced one big win and one big loss. But for the other 298 games, one half of the group experienced all small losses, while the other experienced all small wins.
Cowley also manipulated the distance between the big win and the big loss.
A week later, participants were surveyed for their memories of the experience. Surprisingly, Cowley found that even some losers remembered having a positive experience. If the big win and the big loss occurred far apart, losers had fond memories and indicated a willingness to spend their own money on the game.
As Cowley explains, the further apart the big win and the big loss, the easier it was for losers to isolate their memories and focus only on the positive, a “silver lining” effect.
“The tendency to segregate positive and negative events in a mixed-loss experience is based on the logic that remembering a large gain allows people to feel good even when the objective outcome was negative,” Cowley says.
Conversely, Cowley found that winners – those who experienced 298 small wins – were happier when the big win and the big loss were closer together, allowing them to lump all the games together and ignore the big loss. She termed this the “cancellation effect.”
“When the outcome of an experience including both positive and negative events results in a net gain, people look for ways to integrate positive and negative events to reduce, if not cancel, the pain associated with the negative events,” Cowley explains.
The research is the first to consider a motivated memory explanation for justifying irresponsible behavior. Apparently, positive thinking can sometimes be negative.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
