The mediating role of attitudes toward learning and tolerance of ambiguity in the relationship between the need for cognition and the need for closure on the working memory of High School Students

The purpose of this work is to look into the impact of the need for closure and cognition on the degree of working memory in Tehran high school students, with the role of attitudes toward learning and ambiguity tolerance as mediating factors. To this end, 385 subjects consisting of 155 girls and 230 boys were selected using multi-stage cluster sampling to complete the questionnaires on working memory (Nejati, 2013), the need for cognition (Cachiupo, 1996), the need for closure (De Baker & Krausson, 2008), attitude toward learning (Eiken, 1979) and ambiguity tolerance (McLean, 1993). The study was descriptive, and a correlation design was given in light of investigating the relationships between the variables using a causal model of route analysis. The results revealed that the need for cognition has an indirect effect on working memory through the mediation of the attitude to learning and ambiguity tolerance. Furthermore, the need for closure has an indirect influence on working memory by the mediation of attitude toward learning and ambiguity tolerance. Similarly, the need for cognition has a significant effect on working memory, whereas the need for closure has no such impact. Additionally, the need for cognition has a significant effect on attitude toward learning and ambiguity tolerance, whereas the need for closure has no significant effect on attitude toward learning and ambiguity tolerance. The findings were explored in depth in the conclusion section.
