The somatosensory cortex was localized physiologically with microelectrode penetrations in surgery under barbiturate anesthesia to localize cutaneous somatosensory digit responses in the central sulcus, with the search for responses initiated at +6 mm anterior, and 24 mm lateral.
But the authors say they corrected for that single-digit response rate, which they note is typical for surveys of academics, by weighting the respondents' scores.
And when Republican voters were asked which candidate they preferred to be the party's nominee in 2012, Palin, who often used to sit atop of that list, barely registered a double-digit response, which slotted her into fifth place among a weak field of contenders.
Beyond the very real challenges that polling faces -- from single-digit response rates and the fast growing number of "cell phone only" households -- the Iowa misfire traces to issues that have challenged polls there for decades: large late shifts in voter preferences and the difficulty in predicting exactly who will trek out to caucus meetings on a cold winter night.
When the median-ulnar to digit 4 response was absent, subsequent transpalmar and median-radial to digit 1 testing yielded responses in 39% and 32% of cases, respectively.
We observed no statistically significant differences between the exposure groups with respect to simple attention (Digit Span), response inhibition (Stroop), clerical speed and accuracy (Symbol Digit Modalities Test), or divided attention and mental flexibility (Trails A and B) [see Supplemental Material, Table 1 (doi:10.1289/ehp.1002915)].
Although instructed to reply only with a single digit, SMS responses frequently contained messages of gratitude.
Finally, the probe was presented in Arabic digits until response or until 2000 ms were passed.
In condition B (6-digit sequences), response times in the autism group were longer than in the control group, which appears inconsistent with increased arousal or impulsivity.
