Subclaims¶

q3 i? In adults, attention reliably increased the amplitude of the P1 elicited by nonlinguistic probes, particularly over frontal and left hemisphere electrodes. → Karns Christina M. 2015 q3 i? For 16-year-olds, attention modulation at the nonlinguistic P1 was only a non-significant trend. → Karns Christina M. 2015 (2)

q3 · i? · causal · r2

Peak-amplitude repeated-measures ANOVAs in the dichotic story task showed a significant positive attention effect at the adult nonlinguistic P1, "p < .001", strongest over frontal and left-hemisphere electrodes; 3–5-year-olds also showed a significant positive effect at 165–185 ms.

"in adults, attention reliably increased the amplitude of the P1 elicited by nonlinguistic probes, particularly over frontal and left hemisphere electrodes (p < .001)."

q3 · i? · causal · r2

In the same study, 16-year-olds showed an adult-like P1 latency yet only a trend-level attention modulation (p < .10), which the authors state should not be interpreted as statistically significant; 13-year-olds showed significant modulation at their later P1 peak.

"For 16-year-olds, the P1 had an adult-like latency, but there was only a non-significant trend toward attention modulation at the P1 manifesting as a trend interaction with topography (p < .10)."
