The Importance Of Spatial Perception

Our brain is not equipped to dealing with the vast amount of sensory information that we are exposed to in everyday life, as a consequence information must be selected (Munneke, Stigchel, & Theeuwes, 2008). Researchers are often interested in what factors determine what information is selected.
A question that has drawn considerable interest in cognitive research is whether perception of feelings, thoughts or behaviour is conditional on conscious awareness. A considerable amount of literature support the notion that spatial attention is essential in order to process information (Besner, Risko & Sklair, 2005; McCann, Folk, & Johnston, 1992) In contrast, another major theory argues that spatial attention enhances the processing of information, however it is not entirely dependent on this condition (Munneke et al., 2008; Brown, Gore, & Carr, 2002; Posner & Snyder, 1975).
Our current study was derived from Besner et al. (2005), who conducted four experiments as an attempt to unravel whether spatial awareness is dependent on attention. Spatial cueing and repetition priming was used to test the influence of attention on time to verbally name a target word that would appear

(2008) contended, that a system that responds only to negative events would be maladaptive to functional behaviour, implying that positive stimuli would also bias attention. Supporting this, it is suggested that there is an attentional bias towards emotionally positive stimuli, although this bias is not as strong as negative information (Shen, Fu, & Xuan, 2010). However in contrast it was found that positively valence stimuli had no effect on spatial attention and inhibition (Fox et al., 2002). Supporting Shen et al. (2010) findings from an additional study suggest that there is no attentional bias for positive stimuli, with sexual stimuli as the only exception (Schimmack & Derryberry, 2005). There is little consensus on the influence of positively valence stimuli on spatial
