More and more children are failing to develop secure attachments to loving, protective caregivers. These children are left without the most important foundation for healthy development. They are flooding our child welfare system with an overwhelming array of problems - emotional, behavioral, social, cognitive, developmental, physical and moral - and growing up to perpetuate the cycle with their own children.
When presented as substantive evidence, the animation may be presented as reconstruction or visualization of the actual event. The idea is to show what a witness or defendant could and could not have seen. In this application, it is important to remember that animations and have severe perceptual limitations.
Jurors treat eyewitness identification as compelling evidence in both civil and criminal trials. The strength of eyewitness testimony is demonstrated by a study (cited in Loftus and Doyle, 1992) that recorded verdicts in a mock trial. Although jurors rely heavily on eyewitness identification, there is overwhelming evidence that eyewitness identification is highly fallible and that eyewitness confidence is a poor guide to accuracy.

In this article, we shall provide a brief overview of human information processing limitations and explain how they can contribute to road accidents. This is a "first-principles" approach to accident investigation because it draws on knowledge of basic human psychological processes. Instead of looking at the driver from the outside, we try to understand his/her mental processing and how it interacts with the environment.
Color blindness is not a single problem but a variety of problems that affect color vision. Only a very small portion of people do not see color at all, but view the world in shades of gray. The most common type of color blindness is red/green, which has two forms. Some people are missing red receptor cones and others are missing green receptor cones. People with different forms of red/green color blindness have slight differences in the way they perceive color. Another form of color blindness is blue/yellow, which is less common. While only 8 percent of men are color-blind, they make up 95 percent of the 9,000,000 people in the U.S. who suffer color-vision impairment.
This paper reviews the history of psychological investigations of unconscious perception and summarizes the current status of experimental research in this area of investigation. The research findings described in the paper illustrate how it is possible to distinguish experimentally between conscious and unconscious perception. The most successful experimental strategy has been to show that a stimulus can have qualitatively different consequences on cognitive and affective reactions depending on whether it was consciously or unconsciously perceived.

Development of a comprehensive theory of operant conditioning using robots (Skinnerbots) to demonstrate the workability of the theories developed.
HHMI researchers pinpoint the cause of a mutation that switches a hamster's biological clock to a 20-hour day. Identifying the cause of the tau mutation offers researchers a new tool for understanding biological clocks in humans, as well as a potential target for drugs that control the biological clock.
