  • eye-tracking technology has been around for years, it is now small enough to be used to examine how toddlers view their environment.

      Technology called eye-tracking has been changed so now its small enough to examine toddlers views of the environment.

  • Finn, an 8.5-month-old toddler, was among the participants in this project. She was being coaxed to wear the eye-tracking headgear, which consists of two cameras - one that's looking out on the scene to get the baby's perspective, and another that's looking at the eye to track the movement of the pupil. A computer analyzed both camera views to determine exactly where Finn was looking.

      They tested an 8.5 month-old toddler, named Finn with the new eye tracking gear. The gear weighs only 45.4 grams.

  • infants would be looking at their mothers constantly because that was common knowledge within [the field of] social cognition with infants." But in a room full of toys scattered everywhere and obstacles to climb on and crawl on, the infants only looked toward their mothers about half the time.  And even if they did look at their mothers, they looked at their mothers' faces only about 15 percent of the time.
  • toddlers almost always look directly at the object when reaching for it.
  • Toddlers are able to use information from their peripheral vision and still walk very well.
  • Another interesting finding was that while infants look directly at an obstacle before walking onto or over it, 75 percent of the time they don't always have to.

      The toddlers didn't have to look at the obstacle all the time. they were able to use information for their peripheral vision.
  • According to Franchak, down the line it could offer more research applications that could help infants with developmental disorders, medical research and applied research.

  • The person may show some loss of cognitive function, but you may not immediately see anything in a CT-scan or MRI that tells you exactly where and how much damage has been done to the brain. You don't know what happened to the brain, so how do you figure out how to treat the patient?"

  • In addition to raising the public profile of the disorder, the book also marked the first suggestion that alternate personalities were created as a way to wall off traumatic memories of physical or sexual abuse, and that those memories could be recovered with the help of a therapist.
  • The idea at the time was that the mind locks these memories away, but with the help of a therapist, and through hypnosis or the use of drugs like Sodium Pentothal, these memories could become accessible,
  • Called a “concealed information task,” the test’s goal is ostensibly simple: identify words as they flash on a computer screen. If one of a small set of randomly selected “target” words appears, press yes. For all other words, press no. The catch, McNally said, is that while many of the words hold no meaning for the patients, a small subset of the non-target words are taken from two autobiographical questionnaires patients fill out at the start of the test — one while inhabiting one personality, the second in another.

      They conducted a test and fooled the patients with DID that said that they have no memory of what has happened.
  • When one of those personally relevant words — such as a best friend’s name, favorite food, or favorite sport — appears on screen, McNally said, most patients’ first impulse is to press the yes button. Within moments, however, they realize the word doesn’t appear on the target list, and they eventually give the “correct” answer by pressing no.
  • All participants showed a nearly identical lag for words that were relevant to their alternate personalities, McNally said, suggesting that the information wasn’t locked away in a separate identity.
