Working memory and sexual risk taking in adolescents

29 Jun

Who says memory is unimportant? A recent paper in the journal Child Development reports “Stronger Working Memory Reduces Sexual Risk Taking in Adolescents, Even After Controlling for Parental Influences.” Here is the abstract:

“This study examined the prospective influence of adolescent working memory (WM) on changes in impulsivity and sexual risk taking and assessed whether this relation could be explained by confounding effects of parental influences. Data from 360 community adolescents (Mage = 13.5 ± 0.95 years; 52% female; 56% non-Hispanic White; low-mid socioeconomic status (SES); recruited from Philadelphia area in 2004–2005) were analyzed using structural equation modeling to predict changes in impulsivity and sexual risk taking over a 2-year follow-up, using baseline assessments of WM, parental monitoring, parental involvement, and SES. Stronger WM predicted reduced involvement in sexual risk taking at follow-up, effects channeled through changes in impulsivity dimensions of “acting without thinking” and “inability to delay gratification.” Parental variables had a protective influence on adolescent impulsivity and risk involvement, but the effects of WM operated independently of parental influences.”

An earlier study found a link between working memory and alcohol use:

“Early adolescent alcohol use may be a consequence of (pre-existing) weaknesses in working memory (WM) rather than a cause of it. Efforts to reduce early alcohol use should consider the distinct roles of different impulsivity dimensions, in addition to WM, as potential targets of intervention.”



Bilingual advantage for working memory

10 May

Is there a bilingual advantage for working memory? A paper published in Learning and Individual Differences suggests that there is.

Since bilingual individuals must often process two languages simultaneously,  it seems reasonable to suspect that  the extra cognitive work might confer benefits. Here are the highlights of the paper:

• The four working memory component model exists in mono- and bilingual 8–12 year-old children.
• Working memory construct is conceptualized similarly in mono- and bilingual 8–12 year-old children.
• There were significant differences in the latent factors means that favored the bilinguals in the four WM components.

There is evidence that bilingual individuals are more resistant to dementia.
