The Effect Of Valence, Reward Magnitude And Reward Sensitivity On Value-Driven Attentional Capture

Value-driven attentional capture has grown in popularity in the selective attention field of psychology in recent years.Previous researches that study value-driven spatial attentional capture has produced fruitful findings.In this study,we attempt to investigate the role of valence,reward magnitude and reward sensitivity on temporal selection.In this study,our participants are university students,we use the RSVP paradigm to investigate the mechanism and main factors of value-driven attentional capture by two PSVP experiments.The first experiment manipulates the reward and punishment situation through the gain or loss of money.The aim of this study is to find out whether effects of rewards and punishments on attention are driven by the motivational significance of value signals,or by the valence of the outcome(appetitive or aversive).Second experiment,investigate the effects of reward magnitude and reward sensitivity on value-driven attentional capture.After comparing and combine the results of two experiments mentioned above,following conclusions are reached:(1)The effect of reward and punishment on value-driven attentional capture was broadly similar,suggesting that attentional capture is a function of the motivational significance of the valued outcome,rather than its valence.(2)The distractor stimuli that associates with high reward will capture more attention than low reward.(3)Individuals with high sensitivity to reward are more susceptible to reward magnitude,and they are easily yield themselves to the temptation of reward,even knowing that give attentional priority to reward stimuli is counterproductive,they can't resist the distraction of reward stimuli.
