These findings oriented the attention of the BHP researchers to organizations such as WHO that determined the health programs that were recommended to countries like Guinea Bissau.
"In terms of a medium, wild postings are very street oriented and catch the attention of a younger audience," explained Doug Lloyd, president of Lloyd & Company.
The N2b is considered to be a correlate of covert orienting of attention, attentional capture and identification of stimuli.
The N2 is a negative going wave observed approximately 200 to 350 ms after stimulus onset, maximally at frontocentral sites, and has been associated with several processes such as the covert orienting of attention, the detection of response conflict (conflict monitoring), response inhibition, and error detection (Jodo and Kayama 1992; Nieuwenhuis et al. 2004; Wijers et al. 1989).
Based on the role of pSTS in gaze perception and the tendency for humans to orient their attention toward the direction signaled by others' gaze (Friesen and Kingstone 1998; Driver et al. 1999; Langton and Bruce 1999), we predicted significant PPIs between the pSTS and areas of the dorsal and ventral attention systems discussed above.
Another example of a neurophysiological error signal that is elicited by salient irregular sounds is the P3a, a frontocentral positivity occurring at around 250 300 ms after the onset of the salient sound, which is proposed to reflect the involuntary orienting of attention towards the perturbating sound (Escera et al., 2000; Friedman et al., 2001; Polich, 2007).
Interestingly, a recent fMRI study investigated the ability to orient attention to the semantic categories of words using a cued (semantic or spatial) lexical decision task [31], similar in structure to the Posner attentional orienting task.
Infants were first shown an attention grabbing video of a toy with accompanying audio in order to orient their attention towards the display.
For example, in a recent study, Jaeger et al. (2013) found that distinct areas within the inferior parietal lobe monitor unexpected novelty and unexpected familiarity and proposed that their function is to orient current attention to the unexpected information.
However, there were substantial differences between groups in markers of subsequent processing, including the anterior N2 (a measure of attentional control) and the P3a (an index of the orienting of attention).
