The serotonin transporter polymorphism has been linked--often in interaction with environmental adversity--to a variety of outcomes, including affective disorders. This polymorphism is widely viewed as relating to anxiety traits. A different view is that it relates instead to impulsivity (vs. control) in reacting to emotions. In a test of the latter view, 303 students were genotyped on this polymorphism and completed self-reports bearing on impulsive reactions to emotions (including both negative and positive emotions in separate measures), impulsive tendencies that do not stem from emotions, and childhood adversity. The impulsivity measures reflected three latent variables: pervasive influence of feelings, feelings (including positive feelings) triggering action, and failure to carry through on intentions (with no mention of emotion). Interactions between genotype and adversity emerged for both emotion-related aspects of impulsivity. Theoretical implications of the findings are discussed.
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 12 September 2016.
All research outputs
#14,188,008
of 22,741,406 outputs
Outputs from Psychological Science
#3,613
of 4,197 outputs
Outputs of similar age
#82,449
of 109,278 outputs
Outputs of similar age from Psychological Science
#39
of 56 outputs
Altmetric has tracked 22,741,406 research outputs across all sources so far. This one is in the 35th percentile – i.e., 35% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,197 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 80.7. This one is in the 12th percentile – i.e., 12% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 109,278 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 23rd percentile – i.e., 23% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 56 others from the same source and published within six weeks on either side of this one. This one is in the 26th percentile – i.e., 26% of its contemporaries scored the same or lower than it.
