      Where is the limit between a reflex and a cognitive response?
  • Sean Nash on 01 Jul 24
     
    I really like this topic, and it is one that is getting some current attention. so, we obviously cannot discern cellular-level factors with the nervous system of animals (and obviously- especially when dealing with pain response, we would have to work exclusively with invertebrates and the experimental design would have to be very well thought out. That said, behavioral studies where you have a really tight experimental design set up.... and you're recording behavioral changes... is likely feasible. If this is interesting, keep digging into pain vs. reflex studies, and also begin to look at invertebrate models that we can both successfully raise... and that have interesting behavioral responses we can readily discern in the lab.

Race car drivers tend to blink at the same places in each lap - 2 views

  • The world goes dark for about one-fifth of a second every time you blink, a fraction of an instant that’s hardly noticeable to most people. But for a Formula One race car driver traveling up to 354 kilometers per hour, that one-fifth means almost 20 meters of lost vision
  • People are often thought to blink at random intervals, but researchers found that wasn’t the case for three Formula drivers.
  • the drivers tended to blink at the same parts of the course during each lap, cognitive neuroscientist Ryota Nishizono and colleagues report in the May 19 iScience

      Interesting. So, do we do the same thing while driving around town? Could you design a method to record eye blinks as people drive known routes around town? We could simultaneously use the Arduino Science Journal app on the iPhone to also correlate physical data in a moving car like acceleration/deceleration, motion in X, Y, Z directions, etc. I wonder if we could find a correlation in everyday driving that could help from a safety perspective?

      Ok.... this screams "potential research idea."
  • “We think of blinking as this nothing behavior,” he says, “but it’s not just wiping the eyes. Blinking is a part of our visual system.”
  • Where the drivers blinked was surprisingly predictable, the team found. The drivers had a shared pattern of blinking that had a strong connection with acceleration, such that drivers tended not to blink while changing speed or direction — like while on a curve in the track — but did blink while on relatively safer straightaways.

      What sort of implications does this have for driving in key, known, busy interchanges in KC? Could we potentially provide data to show certain stretches of highway need more signage, etc? That could have civil engineering implications.
  • Nishizono and colleagues mounted eye trackers on the helmets of three drivers and had them drive three Formula circuits
  • Nishizono next wants to explore what processes in the brain allow or inhibit blinking in a given moment, he says, and is also interested in how blinking behavior varies among the general population.
    • Sean Nash
      Sean Nash on 06 Jun 24
       
      While the "brain" part might move beyond our feasibility, the potential of finding real correlations to driving patterns or routes is a completely different spin-off and one that could have really practical suggestive applications for city planners, etc.

  • Scientists studying ultra-processed foods have created a new tool for assessing the rewarding and reinforcing properties of foods that make up 58 percent of calories consumed in the United States. The foods have been linked to a wide range of negative health outcomes.

      I couldn't locate this imageset and associated tools online, but I am willing to bet they might make it available to us, and the generation of more future research in this area is a key purpose of this work.

      Perhaps we just need to get the full journal article to get the raw materials (images) created and used.
  • The scale has its detractors. "A major criticism of the NOVA scale is that it's difficult to use or that foods are classified differently by different people," said Alexandra DiFeliceantonio, corresponding author and assistant professor at the Fralin Biomedical Research Institute. "We found that people with education in nutrition generally agreed on the food classifications, providing some data that it might not be a valid criticism."

      See... this is the sort of thing I see as an opportunity. If the scale has detractors or isn't yet perfect, perhaps there is an opening here for a project. Perhaps there is even an opening to create something focused on teens (who I would argue are at most risk for the consumption of ultra-processed foods). This is an interesting area to me, not only behavioral science, but human diet in general.

  • To develop the picture set, a team of psychologists, neuroscientists, and registered dietitians selected foods to represent either minimally processed or ultra-processed foods.
  • The foods were prepared in a lab, visually represented through professional photography, and controlled for consistency. Researchers also gathered price, food weights, and nutritional information -- calories, macronutrients, sodium, and dietary fiber -- for the food in each image.
  • researchers recruited 67 nutrition professionals and asked them to classify the foods as minimally or ultra-processed
  • "There is very little experimental research on ultra-processed foods, and part of what's been holding us back is better tools for measuring and assessing their effects,"

      Sean Nash on 01 Jun 24
       
      Another big GREEN flag that this is an area ripe for new and creative approaches!
  • The Virginia Tech team is making the pictures and associated data accessible through the Virginia Tech Data Repository of the Virginia Tech University Libraries. This will allow scientists to test hypotheses in behavioral economic and neuroimaging studies.

      This states that the images/research tools WILL BE MADE AVAILABLE (if not already). This is very cool. So, could the already-existing tool be leveraged in a novel way compared to what the researchers used it for, or does this provide somewhat of a template for someone to create a better or more-helpful tool perhaps for teens?

  • Rho's work is grounded in a social science framework called Fuzzy Trace Theory that was pioneered by Valerie Reyna, a Cornell University professor of psychology and a collaborator on this Virginia Tech project. Reyna has shown that individuals learn and recall information better when it is expressed in a cause and effect relationship, and not just as rote information. This holds true even if the information is inaccurate or the implied connection is weak. Reyna calls this cause-and-effect construction a "gist."

      Fuzzy Trace Theory looks interesting for this, and perhaps many other reasons. I want to learn more about this myself, and I'm wondering if this theory could be put to work in other potential behavioral science projects. What do you think?
