Preschool Has Big Advantages for the Disadvantaged
It may seem obvious that preschool helps kids perform better in later grades. But most studies to date have produced limited conclusions about how the preschool environment impacts a child’s academic success. A recent Psychological Science study has filled in some of those gaps. In the study, Elliot Tucker-Drob analyzed a data set that included 1,200 fraternal and identical twins from 600 families. The focus on twins allowed Tucker-Drob to fully account for family-to-family variation as well as genetic influences. He also evaluated each child at two, four, and five years of age to make sure that achievement gaps attributed to preschool didn’t already exist before the preschool years.

The Photos That Make Us Feel
In case you missed it, the cameras were rolling at the APS 23rd Annual Convention in Washington, DC. Watch Kathleen E. Hazlett from Marquette University present her poster session research on “Self Selected Pictures Are More Effective than IAPS for Inducing Positive Emotion.” According to Hazlett, your own photo album (or Facebook timeline, or Flickr account) might be the best pick-me-up when you’re feeling down. Personal photos could also be the best way for researchers to elicit positive emotions in the lab.

Adapting Counseling Strategies for Native Communities
Evidence-based psychotherapy should work the same for everyone, right? Wrong. In his research, Joseph P. Gone of the University of Michigan points out that the latest treatments developed by psychological scientists can’t be applied to all communities in exactly the same way. Gone is interested in how evidence-based mental health treatments and the cultural traditions of American Indians can intersect. This intersection, he says, is elusive. Integrating Native traditions and evidence-based therapy, he points out, may require merging spiritual and mental health practices, and clinicians would have to address difficult ethical and political complications.

Optogenetics: Stranger Than Fiction
It sounds like a science fiction movie: Scientists integrate the photoreceptive properties of light-sensitive algae into rat neurons. The result? A rat whose brain can be controlled by light. As crazy as it seems, this isn’t science fiction: The field of optogenetics is scientific reality. In a May 2011 talk at the TED Conference, Edward Boyden explained that optogenetics allows scientists to target specific neurons quickly; conventional methods like drugs take longer to kick in. Boyden is also featured in a March Observer article on optogenetics, and he will be speaking in a webinar called Optogenetics in Neurons and Beyond on March 15, 2012.

Placebo Power
APS Fellow and Charter Member Irving Kirsch, associate director of the Placebo Studies Program at Harvard Medical School, says the difference between the effect of a placebo and the effect of an antidepressant is minimal for most people. "People get better when they take the drug, but it's not the chemical ingredients of the drugs that are making them better," Kirsch told Lesley Stael in a 60 Minutes interview, "it's largely the placebo effect." The "placebo effect" may not be all in your head says Kirsch in the interview below: Kirsch, I., Deacon, B.J., Huedo-Medina, T.B., Scoboria, A., Moore, T.J., & Johnson, B.T. (2008).

Perfectionism, Goal Appraisals, and Distress in Students
In case you missed it, the cameras were rolling in Washington, DC. Watch. Watch Gordon L. Flett from York University, Canada and Taryn Nepon of York University, Canada present their research at the 23rd APS Annual Convention in Washington, DC. This study examined perfectionism, goal cognitions, and distress in 95 students. Participants completed the Goal Systems Assessment Battery, along with measures of perfectionism, anxiety, and depression. Socially prescribed perfectionism and perfectionistic thoughts were associated with goal-related self-criticism and negative arousal. Self-oriented perfectionism predicted self-criticism and negative arousal for academic goals.
