Berkeley on Biphasic Sleep If you see a student dozing in the library or a co-worker catching 40 winks in her cubicle, don’t roll your eyes. New research from the University of California, Berkeley, shows that an hour’s nap can dramatically boost and restore your brain power. Indeed, the findings suggest that a biphasic sleep schedule not only refreshes the mind, but can make you smarter. Students who napped (green column) did markedly better in memorizing tests than their no-nap counterparts. Conversely, the more hours we spend awake, the more sluggish our minds become, according to the findings. “Sleep not only rights the wrong of prolonged wakefulness but, at a neurocognitive level, it moves you beyond where you were before you took a nap,” said Matthew Walker, an assistant professor of psychology at UC Berkeley and the lead investigator of these studies. In the recent UC Berkeley sleep study, 39 healthy young adults were divided into two groups — nap and no-nap.
16 Personality Factors The Sixteen Personality Factor Questionnaire (or 16PF), is a multiple-choice personality questionnaire which was developed over several decades of research by Raymond B. Cattell, Maurice Tatsuoka and Herbert Eber. Beginning in the 1940s, Cattell used the new techniques of factor analysis (based on the correlation coefficient) in an attempt to try to discover and measure the source traits of human personality (Cattell, 1946)(Nevid, 2009). The questionnaire measures the 16 primary traits, and the Big Five secondary traits, which have become popularized by other authors in recent years. The test is an integral part of Cattell's comprehensive theory of individual differences. Outline of Test The 16PF Fifth Edition contains 185 multiple-choice items which are written at a fifth-grade reading level. When I find myself in a boring situation, I usually "tune out" and daydream about other things. Raymond Cattell's 16 Personality Factors Factor Analytic Strategy
Color symbolism Color symbolism in art and anthropology refers to the use of color as a symbol in various cultures. There is great diversity in the use of colors and their associations between cultures and even within the same culture in different time periods. In fact, the same color may have very different associations within the same culture at any time. For example, red is often used for stop signs or danger. At the same time, red is also frequently used in association with romance, e.g. with Valentine's Day. White variously signifies purity, innocence, wisdom or death. Symbolic representations of religious concepts or articles may include a specific color with which the concept or object is associated. There is evidence to suggest that colors have been used for this purpose as early as 90,000 BC. Extensive associations for each color are listed in their respective articles.

Neuroscience Neuroscience is the scientific study of the nervous system. Traditionally, neuroscience has been seen as a branch of biology. However, it is currently an interdisciplinary science that collaborates with other fields such as chemistry, computer science, engineering, linguistics, mathematics, medicine and allied disciplines, philosophy, physics, and psychology. It also exerts influence on other fields, such as neuroeducation and neurolaw. The term neurobiology is usually used interchangeably with the term neuroscience, although the former refers specifically to the biology of the nervous system, whereas the latter refers to the entire science of the nervous system. Because of the increasing number of scientists who study the nervous system, several prominent neuroscience organizations have been formed to provide a forum to all neuroscientists and educators. History The study of the nervous system dates back to ancient Egypt. Modern neuroscience Human nervous system

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. 1. 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. This infamous experiment to plumb the depths of evil in human hearts ended up affecting its lead researcher as much as its subjects. 3. 4.

Color Symbolism Theories (Article source: Color Logic for PowerPoint) Color conveys meanings in two primary ways - natural associations and psychological symbolism. No, it’s not mind control. The truth of the matter is that people are comfortable when colors remind them of similar things. For example, a soft shade of blue triggers associations with the sky and a psychological sense of calm. Successful design requires an awareness of how and why colors communicate meaning. As a starting point, the communicative properties of a color can be defined by two categories: natural associations and psychological (or cultural) associations. Natural Associations Occurrences of colors in nature are universal and timeless. Psychological or Cultural Associations Color may generate another level of meaning in the mind. Furthermore, color may have both positive and negative symbolism. Advertisement 1. 2. 3. 4. 5.

An On-Off Switch for Anxiety With the flick of a precisely placed light switch, mice can be induced to cower in a corner in fear or bravely explore their environment. The study highlights the power of optogenetics technology—which allows neuroscientists to control genetically engineered neurons with light—to explore the functions of complex neural wiring and to control behavior. In the study, Karl Deisseroth and collaborators at Stanford University identified a specific circuit in the amygdala, a part of the brain that is central to fear, aggression, and other basic emotions, that appears to regulate anxiety in rodents. They hope the findings, published today in the journal Nature, will shed light on the biological basis for human anxiety disorders and point toward new targets for treatment. “We want to conceptualize psychiatric disease as real physical entities with physical substrates,” says Deisseroth.
