dc.description.abstractAccuracy at identifying or detecting a second-target (T2) is reduced if presented within approximately 500 ms of the first target (TI) - an attentional blink (AB). Affect has previously been shown to influence the magnitude of the AB such that positive affect (PA) is associated with smaller ABs. To account for these findings, Olivers and Nieuwenhuis (2005) proposed an overinvestment hypothesis where P A was said to reduce overinvestment of attentional resources in TI and distractors, leaving more resources for T2. In the present study, P3, CNV, and average activation on distracter-only trials were used to measure attentional investment. The goal was to investigate whether these electrophysiological measures mediated the relationship between self-reported affect and the AB. Results demonstrated that investment of attentional resources was not associated with self-reported affect, or AB magnitude. However, self-report measures of affect, personality and electrophysiological measures of investment did follow some predictions derived from the overinvestment hypothesis.en_US
