The first series of the experiments examined the roles of integrated representations in location negative priming. The results showed that location negative priming manifests only when both the object features and the location feature were highly activated such that the integrated representations of the distractors were competitive in selecting a target. The second series of experiments examined via a matching task the effect of perceptual similarity between the primes and probes on the negative priming effect. The results showed that distractors must be competitive in selection via the integration of color and shape and also prime-probe couplets were similar in color composition. The results from the present project suggested that integrated representations must be in high activation so that distractors impose high competition in target selection. The inhibition operates on the goal-derived feature and the inhibited representations rely on memory retrieval to reveal negative priming.application/pdf54957 bytesapplication/pdfzh-TW國立臺灣大學心理學系暨研究所負向促發選擇注意力Selective attentionnegative primingreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/9729/1/922413H002025.pdf
