We conducted experiments during trick-or-treating on Halloween in a predominantly liberal neighborhood in the weeks preceding the 2008 and 2012 presidential elections. We decorated one side of a house porch with McCain material in 2008 (Romney material in 2012) and the other side with Obama material. Children were asked to choose a side, with half receiving the same candy on either side and half receiving more candy to go to the McCain/Romney side. This yields a “candy elasticity” of children’s political support. Results vary by age: children ages nine and older were two to three times more likely to choose the Republican candidate when offered double candy for voting Republican compared to when offered equal candy, whereas children ages eight and under were particularly sticky and did not waver in their choice of candidate despite the offer of double candy….
Children’s responses to the candy incentives varied by age, however. Younger children’s preference for Obama was sticky with respect to price, but older children’s preference for Obama was elastic. This result was first observed in 2008 and then successfully replicated in the 2012 experiment. We discuss several interpretations in the conclusion, including a differential response to symbolic versus monetary rewards, a parental-contamination story for the younger children, and the simplest possibility: that younger children just didn’t understand the task as much and so made the political choice they did understand.
“Why do we like the music we do? Research has shown that musical preferences and personality are linked, yet little is known about other influences on preferences such as cognitive styles. To address this gap, we investigated how individual differences in musical preferences are explained by the empathizing-systemizing (E-S) theory. ”
BONUS: Some researchers suggest there is no clearly definable thing that ought to be called a “cognitive style”.
Takahiro Wada, Normia Kamiji, and Shunichi Doi of Ritsumeikan University recently examined an application of a model of motion sickness incidence (MSI) (which Wada, Kamiji, and others developed in a 2007 paper) to vehicle passengers. They generalized earlier work by including more types of motion — especially head rotation — and they used the model to examine the effect of head-tilt strategy on motion sickness:
Thus, the effect of the head tilt strategy on motion sickness was investigated by the proposed mathematical model. The head movements of drivers and passengers were measured in slalom driving. Then, the MSI of the drivers and that of the passengers predicted by the proposed model were compared.
Love, Sex, and Choices (LSC) is a soap opera video series created to reduce HIV sex risk in women.
METHODS: LSC was compared to text messages in a randomized trial in 238 high-risk mostly Black young urban women. 117 received 12-weekly LSC videos, 121 received 12-weekly HIV prevention messages on smartphones. Changes in unprotected sex with high risk partners were compared by mixed models.
RESULTS: Unprotected sex with high risk men significantly declined over 6 months post-intervention for both arms, from 21-22 acts to 5-6 (p < 0.001). This reduction was 18% greater in the video over the text arm, though this difference was not statistically significant. However, the LSC was highly popular and viewers wanted the series to continue.
CONCLUSION: This is the first study to report streaming soap opera video episodes to reduce HIV risk on smartphones. LSC holds promise as an Internet intervention that could be scaled-up and combined with HIV testing.
This study is not yet open for participant recruitment.

Estimated Study Completion Date: March 2019
Estimated Primary Completion Date: December 2017 (Final data collection date for primary outcome measure)
PURPOSE: This study tests a 12-episode Internet-based, guide enhanced Love, Sex, & Choices (LSC) HIV prevention soap opera video series for smartphones or computers, in a randomized clinical trial among predominately at-risk African American urban women.
The following hypotheses are to be tested: 1) The LSC treatment arm will show lower unprotected sex risk, meaning lower frequency of unprotected sex (vaginal + anal) with high risk partners at 6 months post intervention compared to an attention control arm 2) The LSC treatment arm will show higher participation in HIV testing at 6 months post intervention compared to the control.
