The Ten Most Revealing Psych Experiments Psychology is the study of the human mind and mental processes in relation to human behaviors - human nature. Due to its subject matter, psychology is not considered a 'hard' science, even though psychologists do experiment and publish their findings in respected journals. Some of the experiments psychologists have conducted over the years reveal things about the way we humans think and behave that we might not want to embrace, but which can at least help keep us humble. That's something. 1. 'Lord of the Flies': Social Identity Theory The Robbers Cave Experiment is a classic social psychology experiment conducted with two groups of 11-year old boys at a state park in Oklahoma, and demonstrates just how easily an exclusive group identity is adopted and how quickly the group can degenerate into prejudice and antagonism toward outsiders. Researcher Muzafer Sherif actually conducted a series of 3 experiments. 2. 3. 4. 5. 6. 7. 8. 9. 10. Turns out that it's all about framing.

Researchers show that memories reside in specific brain cells Our fond or fearful memories — that first kiss or a bump in the night — leave memory traces that we may conjure up in the remembrance of things past, complete with time, place and all the sensations of the experience. Neuroscientists call these traces memory engrams. But are engrams conceptual, or are they a physical network of neurons in the brain? In a new MIT study, researchers used optogenetics to show that memories really do reside in very specific brain cells, and that simply activating a tiny fraction of brain cells can recall an entire memory — explaining, for example, how Marcel Proust could recapitulate his childhood from the aroma of a once-beloved madeleine cookie. In that famous surgery, Penfield treated epilepsy patients by scooping out parts of the brain where seizures originated. Fast forward to the introduction, seven years ago, of optogenetics, which can stimulate neurons that are genetically modified to express light-activated proteins. False memory

Nainen ilman muistia Maanantaiblogi Virpi Kalakoski Ajattele, jos todella eläisit vain tässä hetkessä, kuten amerikkalainen Lonni Sue. Jokainen päivä ja jokainen hetki on uusi, ihmeellinen ja innostava. Mutta siitä ei muista mitään parin minuutin kuluttua. TIME-lehden tiedepalstalla esiteltiin lokakuun lopulla harvinainen muistipotilas, Lonni Sue. TIME-lehden verkkosivulla esitellään tapausta muutamassa videopätkässä. Myös Lonni Suen läheiset kykenevät näkemään tilanteessa jotakin hyvää. Yhdessä videoista Michael McCloskey, tapauksen tutkija John Hopkins yliopistosta, haastattelee Lonni Sueta 9/11 -tapahtuman tiimoilta. TIME-lehden videot Lonni Suen muistista

Cloning & Synthetic Biology Overview of Traditional Cloning Traditional Cloning refers to the generation of DNA fragments using restriction enzymes, and their subsequent assembly and transformation. The name is derived from the method’s history as the first widely-accepted cloning method. Learn more about the benefits and disadvantages of Traditional Cloning. scroll to see additional videos

New neurons help us to remember fear Fear burns memories into our brain, and new research by University of California, Berkeley, neuroscientists explains how. Scientists have long known that fear and other highly emotional experiences lead to incredibly strong memories. In a study appearing online today (Tuesday, June 14) in advance of publication in the journal Molecular Psychiatry, UC Berkeley’s Daniela Kaufer and colleagues report a new way for emotions to affect memory: The brain’s emotional center, the amygdala, induces the hippocampus, a relay hub for memory, to generate new neurons. The figure shows newly born nerve cells (green) colocalizing with a neuronal marker which indicates immature nerve cells (red). In a fearful situation, these newborn neurons get activated by the amygdala and may provide a “blank slate” on which the new fearful memory can be strongly imprinted, she said. “Many affective disorders involve disordered emotional memories like PTSD, depression and anxiety.

ps3ihmisentiedonkäsittelynperusteet - rongasanne Mitä aivoissasi tapahtuu, kun luet tätä tekstiä? Psyyken toiminnot eivät ole pelkästään abstrakteja käsitteitä ja kielellisesti ilmaistavia teorioita. Kun opit uusia asioita, aivosi muuttuvat konkreettisesti. Ihmisen aivot ovat erityislaatuiset, sillä niillä on kyky tuottaa havaintojen pohjalta mielikuvia, abstrakteja käsitteitä ja luoda kokonaan uusia havainnoista riippumattomia symboleja. Ihmisen muisti toimii monipuolisesti. Mitä aivoissani tapahtuu juuri nyt? Tällä kurssilla huomion kohteena on se, kuinka havaitsemme, suuntaamme tarkkaavaisuuttamme, valikoimme ympäristön ärsykkeistä merkitykselliset, annamme merkityksiä havainnoille, muistamme ja unohdamme.
