Young people who go out drinking start earlier and consume more and more alcohol - 0 views

  • According to results, males drink more and aim to get drunk yet they associate their alcohol intake with the possibility of developing an addiction to a lesser extent than females.
  • We have observed that university students progressed to drink more alcohol. When they were adolescents they drank less alcohol and then more when reaching university. Nonetheless, today's adolescents drink the same amount as university students," outlines Espejo.
  • What will happen to these adolescents in a few years
  • ...9 more annotations...
  • If intake levels for secondary school and university students of the same sex are similar, this means that when secondary school students reach the age of 20, the consequences will be much greater than those seen amongst current university students.
  • "Nearly all adolescents who consumed alcohol started at around 13 or 14 years of age by drinking distilled alcohol (drinks with high alcohol content) in large quantities. On the other hand, university students started between 14 and 15 with fermented drinks like beer in relatively low quantities," confirms the expert.
  • the main reason for alcohol consumption in both groups is to have fun
  • The consequences are not understood
  • As for the consequences associated with alcohol consumption, neither youngsters nor university students are aware of the consequences.
  • They only take into consideration those consequences that repeatedly appear in television campaigns, like those relating to drink driving and personal relationship problems due to aggression.
  • They are also only aware of the immediate physical consequences like vomiting, dizziness, falling over and hangovers, etc.
  • ather that it is not recognised," concludes the researcher.
  • n general, youngsters feel that their alcohol consumption will have no negative consequences. They believe that for this to occur they would have to greatly increase their alcohol consumption. This, however, does not imply that the problem does not already exist but

  • quality face-time with your tot is very important for speech development – more than, say, turning on the latest baby DVD.
  • Other studies have shown that babies who are best at distinguishing between vowel sounds like "ah" and "ee" shortly before their first birthday wind up with better vocabularies and pre-reading skills by kindergarten.
  • babies also look to speakers' faces for important social cues about what they're hearing
  • So he and doctoral student Amy Hansen-Tift tested nearly 180 babies, groups of them at ages 4, 6, 8, 10 and 12 months. How? They showed videos of a woman speaking in English or Spanish to babies of English speakers. A gadget mounted on a soft headband tracked where each baby was focusing his or her gaze and for how long.
    • Katie Raborn
       
      Lewkowicz and Hansen tested how babies learn
  • They found a dramatic shift in attention: When the speaker used English, the 4-month-olds gazed mostly into her eyes. The 6-month-olds spent equal amounts of time looking at the eyes and the mouth. The 8- and 10-month-olds studied mostly the mouth.
    • Katie Raborn
       
      Different age groups studied the speaker differently.
  • At 12 months, attention started shifting back toward the speaker's eyes.
  • at 6 months, babies begin observing lip movement, Lewkowicz says, because that's about the time babies' brains gain the ability to control their attention rather than automatically look toward noise.

  • To examine why infants need to dwell on objects to learn about them, the researchers created two different models. One model learned in a "responsive" world: Every time the model looked away from a new object, the object was jiggled to get the model to look at it again. The other model learned in a "nonresponsive" world: when this model looked at a new object, objects elsewhere were jiggled to distract it. The results showed that the responsive models“learned about new objects more robustly, more quickly, and are better learners in the end,
  • infants can familiarize themselves with new objects, and store them into memory well enough that when shown them again, they quickly recognized them
  • “if that’s the case, we can manipulate and change what the brain is doing” to aid infants born prematurely or who have special needs, Perone adds.

  • 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.

  • The first recorded, probable case of fatal human-to-cat transmission of the pandemic H1N1 flu virus occurred in Oregon in 2009, Loehr said. Details were published in Veterinary Pathology, a professional journal. In that instance, a pet owner became severely ill with the flu and had to be hospitalized. While she was still in the hospital, her cat - an indoor cat with no exposure to other sick people, homes or wildlife - also died of pneumonia caused by an H1N1 infection.
