The principles of cognitive behavioral therapy (CBT) are based on a very simple idea: we feel according to what we think, in other words, our thoughts and cognitive constructions are at the root of our emotions and behavior patterns. CBT is based on three fundamental propositions:
- Cognitive activity affects behavior;
- Cognitive activity may be monitored and altered; and
- Desired behavior change may be effected through cognitive change.
CBT is a fundamentally empowering approach, in that it has successfully identified certain ways of thinking that can make the difference between sanity and insanity, between happiness and unhappiness, and it has developed a variety of techniques to teach patients to substitute these dysfunctional patterns of thinking, which are often at the root of their problems.
The purpose of the present study was to determine the efficacy of investigating spatial cognitive abilities across two primate species using virtual reality. In this study, we presented four captive adult chimpanzees and 16 humans (12 children and 4 adults) with simulated environments of increasing complexity and size to compare species’ attention to visuo‐spatial features during navigation. The specific task required participants to attend to landmarks in navigating along routes in order to localize the goal site. Both species were found to discriminate effectively between positive and negative landmarks. Assessing path efficiency revealed that both species and all age groups used relatively efficient, distance reducing routes during navigation. Compared to the chimpanzees and adult humans however, younger children’s performance decreased as maze complexity and size increased. Surprisingly, in the most complex maze category the humans’ performance was less accurate compared to one female chimpanzee. These results suggest that the method of using virtual reality to test captive primates, and in particular, chimpanzees, affords significant cross‐species investigations of spatial cognitive and developmental comparisons.
Every year for more than a decade, intellectual impresario and Edge editor John Brockman has been asking the era’s greatest thinkers a single annual question, designed to illuminate some important aspect of how we understand the world. In 2010, he asked how the Internet is changing the way we think. In 2011, with the help of psycholinguist Steven Pinker and legendary psychologist Daniel Kahneman, he posed an even grander question: What scientific concept will improve everybody’s cognitive toolkit? The answers, featuring a wealth of influential scientists, authors, and thought-architects, were recently released in This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking — a formidable anthology of short essays by 151 of our time’s biggest thinkers on subjects as diverse as the power of networks, cognitive humility, the paradoxes of daydreaming, information flow, collective intelligence, and a dizzying, mind-expanding range in between. Together, they construct a powerful toolkit of meta-cognition — a new way to think about thinking itself.
Cognitive loss and brain degeneration currently affect millions of adults, and the number will increase, given the population of aging baby boomers. Today, nearly 20 percent of people age 65 or older suffer from mild cognitive impairment and 10 percent have dementia.
UCLA scientists previously developed a brain-imaging tool to help assess the neurological changes associated with these conditions. The UCLA team now reports in the February issue of the journal Archives of Neurology that the brain-scan technique effectively tracked and predicted cognitive decline over a two-year period.
Children who play with puzzles between ages 2 and 4 later develop better spatial skills, a study by University of Chicago researchers has found. Puzzle play was found to be a significant predictor of spatial skill after controlling for differences in parents’ income, education and the overall amount of parent language input.
“The children who played with puzzles performed better than those who did not, on tasks that assessed their ability to rotate and translate shapes,” said psychologist Susan Levine, a leading expert on mathematics development in young children.
