#### 2.3.2 Participants  
The subjects first participated in the BIF Construal Level Personality Test ([PERSON] and [PERSON] 1989) for classification. The BIF consists of 25 items, each with 2 abstract and concrete options that describe behavior. For example, the behavior \"washing clothes\" displays the following options: \"looks clean (abstract explanation)\" or \"puts clothes in the washing machine (concrete explanation)\". The users choose the behavior they think is appropriate from 25 descriptions and select the option of an explanation for each question. An abstract answer scores 1, otherwise, it scores 0. The total score is a BIF index, with the median as the dividing line. The higher the score, the more abstract the user's construal personality trait, and the lower the score, the more concrete the user's personality trait.  
As shown in Table 2, the subjects participating in the BIF are all undergraduates and postgraduates, totaling 80 people. After the experiment, users with fuzzy construal level traits close to the median were excluded, and 32 high construal level users were retained (16 males, 16 females), along with 32 low construal level users (14 males, 18 females). The subject age was between 24 and 28 years old (M = 25.72, SD = 1.27), and all had good computer experience. All were right-handed, with uncorrected or corrected visual acuity above 1.0. Before the experiment, the subjects were introduced to the experimental process, and the subjects were made familiar with the graphic materials (non-linguistic) of the experiment in advance, so that they could better complete the experimental tasks. The subjects gave gifts to express their gratitude after they completed the experiment.
