blog postsWhen emotional memories intrude, focusing on context could help, study findsJun 14, 2018 12:15 pm871 views When negative memories intrude, focusing on the contextual details of the incident rather than the emotional fallout could help minimize cognitive disruption and redirect the brain’s resources to the task at hand, suggests a new study by psychologists at the University of Illinois. “Everyone has encountered something distressing either in the recent past or the remote past. These memories can pop into our minds and distract from whatever we are doing,” said study leader Florin Dolcos, a professor of psychology at Illinois. “Instead of suppressing or stifling those emotional memories, we simply shift the focus and bring to life some other aspects of the same memory. That leads to a reduction in how much those memories interfere with whatever we’re doing.”Study: Larger sample sizes needed to increase reproducibility in neuroscience studiesJun 7, 2018 8:45 am397 views Small sample sizes in studies using functional MRI to investigate brain connectivity and function are common in neuroscience, despite years of warnings that such studies likely lack sufficient statistical power. A new analysis reveals that task-based fMRI experiments involving typical sample sizes of about 30 participants are only modestly replicable. This means that independent efforts to repeat the experiments are as likely to challenge as to confirm the original results.New algorithm fuses quality and quantity in satellite imageryJun 4, 2018 8:30 am970 views Using a new algorithm, University of Illinois researchers may have found the solution to an age-old dilemma plaguing satellite imagery – whether to sacrifice high spatial resolution in the interest of generating images more frequently, or vice versa. The team’s new tool eliminates this trade-off by fusing high-resolution and high-frequency satellite data into one integrated product, and can generate 30-meter daily continuous images going back to the year 2000.
