Subclaims¶

q2 i? When teachers and classmates were asked about students' subject-specific self-concepts, no contrast effects from dimensional comparisons emerged; Dai (2002) found dimensional comparison effects only for parents judging children's abilities, not self-concepts. → Jens Möller 2024

The review reports that "When teachers (Marsh et al., 1984) and classmates (Pohlmann et al., 2004) were asked about students’ subject-specific self-concepts, no contrast effects from dimensional comparisons emerged", while Dai (2002) found such effects for parents judging abilities.

Learner Variables¶

• Academic Self-Concept — outcome: instruction changes it

Related Claims¶

• Dimensional comparison effects extend to subjective task values, with contrast effects strongest for intrinsic value and costs and lowest for utility value, often mediated by self-concept — related
• The net effect of dimensional comparisons is contested: early evidence suggested a positive net effect, but later experiments found downward and upward effects cancel out — related
• Dimensional comparisons: achievement–self-concept paths are positive in similar subjects but negative in dissimilar subjects — related
• Subject similarity moderates dimensional comparison effects: far comparisons (e.g., math vs. verbal) yield strong contrast effects, near comparisons yield weaker contrast or assimilation effects — related
