摘要
研究发现和奖赏关联的刺激会更突显从而捕获注意难以抑制其加工优势。为揭示奖赏学习对情绪注意捕获加工的影响,本研究用奖赏学习范式考察情绪面孔习得奖赏联结后对目标的干扰作用特点。在奖赏训练阶段将三种情绪面孔和不同程度奖赏建立学习联结;测试阶段考察情绪面孔对目标任务完成的干扰是否受到奖赏学习调节。结果显示,高奖赏条件下,相比高兴和中性面孔,恐惧面孔作为非目标刺激时被试完成任务反应时更短,揭示了奖赏学习能有效调节注意资源,且对恐惧面孔干扰具有削弱作用。
Reward facilitates performance and improves cognitive ability in many tasks.In recent years,with the deepening of the research on reward learning,it has been found that the stimulation after reward learning can always get priority in processing.Reward learning refers to establishing an association between characteristics of stimuli and rewards through accentuation training.At the same time,emotional stimuli were consistently prioritized for attention as task-irrelevant stimuli,compared to non-emotional stimuli.As significant stimuli,both emotional and non-emotional stimuli can affect attention processing.At present,the research on reward is mainly focused on the attention processing of physical stimuli with low visual features,such as stimulus color,shape,spatial position,and neutral face.Emotional faces are more salient than the above stimuli,and the top-down perceptual priming is faster.The association of emotional face attention processing advantage and different levels of reward signals may further strengthen the individual's inhibition of distractor,attention modulation,and enhance the processing of target.Therefore,this study uses the associative learning paradigm to establish the learning association between rewards and emotional faces.In the test task,it is further investigated that whether establishing association of different reward value can regulate the allocation of attention resources and influence the processing of non-target emotional stimuli on the target task.Twenty-nine participants(14 males,15 females)were recruited according to the sample size calculated by G-power.Participants completed a line segment orientation task.Emotional faces were presented as non-target interfering stimuli in the experiment.First,the participants completed the baseline task,and then performed training and test.During the training phase,participants were given value feedback when they correctly responded to the target to establish reward association between emotional faces(happy,fearful and neutral)and reward(low rew
