It should be noted that the saliency detection is an improved version from the original method in[13], because we have exactly known the size of the salient target.
The fastest responses were obtained when a salient target was presented, while responses were slowest with target-absent conditions, which required extensive evaluation of the visual scene.
Similar spillover of affect from unattended sources, for example, of unattended physical discomfort leading to anger at a salient target, may be widespread and better supported in everyday life.
The proposed approach describes high-dimensional data in the form of biquaternion and utilizes the phase spectrum of biquaternion Fourier transform to generate a required saliency map that can be used for salient target detection.
As recently suggested, the use of both emotionally salient target and distractor stimuli [32], [35] can overcome this limitation.
N2pc amplitude has been shown to be sensitive to shifts of attention between a highly salient distractor and a less salient target [16] [17].
For a salient target in Fig. 6A, the probability of the target within the context is relatively low, and the saliency measure will be high.
The pre-saccadic parietal alpha and posterior ERP waveform together leads us to suggest that top-down control is implemented in multiple mechanisms that determined whether the first saccade would be directed to the less salient target, or be captured by the salient distractor.
Overall, these behavioural findings strongly suggest that, as expected, at this late processing level the volunteers conjointly deployed visual attention processing resources onto the salient target-category within the relevant spatial location mostly neglecting visual input from the irrelevant location.
We further distinguished the subset specifically using a 'peer support worker' defined as someone who 'shares salient target population similarities (e.g. age, ethnicity, health concern, or stressor) and possesses specific knowledge that is concrete, pragmatic and derived from personal experience rather than formal training' [ 24].
