相对于标准模型的情绪效价，它假设一个双极效价维度，范围从消极到积极的效价与中性中点，评价空间模型（ESM）提出了两个独立的积极和消极的维度。以前的成像研究表明，在调查语言刺激的神经相关性时，ESM的预测能力更高。本研究进一步探讨行为层面的假设。对600多个德语单词的评级实验揭示了48种情感矛盾刺激（即，在随后的两个词汇判断实验中，将这两个维度上得分较高的刺激与中性刺激进行对比。实验二发现了情绪矛盾词的促进加工。此外，在控制情绪唤醒和语义模糊的刺激集，实验3仍然揭示了速度和准确性的权衡情绪矛盾的话。词汇处理和ESM的未来调查的影响进行了讨论。
In contrast to standard models of emotional valence, which assume a bipolar valence dimension ranging from negative to positive valence with a neutral midpoint, the evaluative space model (ESM) proposes two independent positivity and negativity dimensions. Previous imaging studies suggest higher predictive power of the ESM when investigating the neural correlates of verbal stimuli. The present study investigates further assumptions on the behavioral level. A rating experiment on more than 600 German words revealed 48 emotionally ambivalent stimuli (i.e., stimuli with high scores on both ESM dimensions), which were contrasted with neutral stimuli in two subsequent lexical decision experiments. Facilitative processing for emotionally ambivalent words was found in Experiment 2. In addition, controlling for emotional arousal and semantic ambiguity in the stimulus set, Experiment 3 still revealed a speed-accuracy trade-off for emotionally ambivalent words. Implications for future investigations of lexical processing and for the ESM are discussed.
