Across two studies, we aimed to test whether growth mindsets assessed using a relational implicit measure (the mousetracking-based PEP; Cummins & De Houwer, 2021) predicted post-failure learning behavior in an IQ assessment situation. Mousetracking is a superior method at capturing the nuances of evaluation dynamics (e.g., Schneider et al., 2015) and it has been recently found to be more sensitive to relational information than the reaction time version (Cummins & De Houwer, 2022). In both studies, participants were invited for an IQ assessment to the laboratory where they first completed the PEP adapted to assess intelligence mindset. Then, all participants attempted to solve a block of very difficult IQ test items (e.g., Nagy et al., 2021). Subsequently, participants received performance feedback (which was low overall, creating a failure experience, which is a crucial theoretical condition for mindsets to become relevant (e.g., Yeager & Dweck, 2020). Thereafter, they had the opportunity to learn how to solve the difficult IQ items. Time spent on learning about the solutions (time-based learning) and the number of solutions reviewed (item-based learning) served as behavioral indicators for engagement in learning (Porter et al., 2020).
In both studies, our preregistered confirmatory hypothesis was that the PEP measure of growth mindset would predict post-failure learning behavior. The only preregistered control variable was self-efficacy because it is known to affect motivation in achievement situations (Elliot et al., 1999; Elliot & Church, 1997) and has been used in similar studies on mindset, exploring the effect of growth mindset in the face of setbacks (e.g., Song et al., 2020).
Study 1
In Study 1 (N = 184), we assessed implicit growth mindset with the spelling-error variant of the mousetracking PEP (Cummins & De Houwer, 2021).
Results
Linear regression (preregistered analysis). The preregistered analysis showed that implicit growth mindset was predictive of the time-based post-failure learning behavior (b = 22.03, 95% CI [2.19, 41.88], t(181) = 2.19, p = 0.030), while controlling for self-efficacy (b = 25.30, 95% CI [5.45, 45.15], t(181) = 2.515, p = 0.013). Furthermore, we analyzed our secondary pre-registered dependent variable (i.e., the number of solutions reviewed). Similarly, we found that implicit growth mindset predicted the number of items reviewed (b = 0.61, 95% CI [0.10, 1.13], t(181) = 2.36, p = 0.019), while controlling for self-efficacy (b = 0.86, 95% CI [0.35, 1.38], t(181) = 3.31, p = 0.001). Thus, our preregistered hypothesis was fully supported by both preregistered dependent variables, a stronger implicit growth mindset was associated with higher engagement in learning.
Two-step model (exploratory analysis). The normality assumption of residuals of the pre-registered analyses were not met (as assessed by a Kolmogorov-Smirnov test; D = .167, p < 0.001). Therefore, first, we transformed the primary outcome variable and applied a two-step model (logistic and linear regressions), where we were interested in the linear part of the model (see explanation in the statistical analysis section). We found that implicit growth mindset was not predictive of the choice to view any solutions in the logistic model (OR = 1.13, 95% CI [0.70, 1.87], p = 0.635), when controlling for self-efficacy (OR = 1.46, 95% CI [0.92, 2.33], p = 0.107). However, implicit growth mindset predicted the time spent viewing the solutions among those who chose to view any solutions in the linear model, when controlling for self-efficacy (see Table 2). Thus, those with stronger implicit growth mindsets dedicated a greater amount of time to learn from their mistakes.
For the secondary outcome, we applied a right-censored Poisson regression (see details in the statistical analysis section), which supported the main analysis: we found that implicit growth mindset also predicted the number of solutions reviewed among those who chose to view any solutions, when controlling for self-efficacy (Table 2). Those individuals who had a stronger implicit growth mindset reviewed more solutions.

Note. M and SD are used to represent mean and standard deviation, respectively. Values in square brackets indicate the 95% confidence interval for each correlation. Correlations of Study 1 are presented in the bottom left part of the table and correlations of Study 2 are presented in the upper right part of the table. Analyses were run among participants who reviewed at least one solution – see explanation under Statistical Analysis section (Study 1: N = 164; Study 2: N = 177).

The role of explicit growth mindset (exploratory analysis). Our aim with these analyses was to explore if implicit growth mindset explained any variance in addition to explicit growth mindset for which we further applied the two-step model. We found that implicit growth mindset was significantly associated with the time spent on viewing the solutions (b = 0.86, 95% CI [0.06, 1.67], p = 0.035), while explicit growth mindset was not a significant predictor (b = 0.73, 95% CI [-0.06, 1.53], p = 0.071), when controlling for self-efficacy (b = 0.90, 95% CI [0. 10, 1.71], p = 0.027). In the binomial part of the two-step model, none of the variables predicted the decision to view solutions (implicit growth mindset: OR = 1.13, 95% CI [0.70, 1.89], p = 0.624; explicit growth mindset: OR = 1.20, 95% CI [0.76, 1.88], p = 0.419; self-efficacy: OR = 1.45, 95% CI [0.91, 2.32], p = 0.116).
Moreover, we applied the same censored Poisson model among the nonzero values to predict the secondary dependent variable, including the explicit score of intelligence mindset. Here we found that both the implicit (IRR = 1.14, 95% CI [1.08, 1.22], p < 0.001) and explicit scores of growth mindset (IRR = 1.10, 95% CI [1.03, 1.18], p = 0.007) predicted learning behavior (i.e., the number of items viewed), when controlling for self-efficacy (IRR = 1.16, 95% CI [1.09, 1.24], p < 0.001). The relationship is represented in Fig. 1.
Study 2
The aim of Study 2 (N = 193) was to replicate the results of Study 1 with an improved and more reliable measure assessing intelligence mindsets implicitly. Specifically, we used the truth-evaluation variant of the PEP, which had previously demonstrated higher reliabilities than the spelling-error variant (Cummins & De Houwer, 2021; Müller & Rothermund, 2019) and made further adjustments to make the task more reliable and user-friendly. Otherwise, the procedure and design of the study was the same as in Study 1.
Results
Two-step model (preregistered analysis). Based on the data of Study 1, we expected that the number of viewed solutions will not be normally distributed. Therefore, in Study 2, we directly pre-registered the two-step model. Consistent with our preregistration, when holding self-efficacy constant (OR = 0.99, 95% CI [0.59, 1.67], p = 0.984), the decision to view any solutions was not predicted by implicit growth mindset (OR = 1.10, 95% CI [0.65, 1.80], p = 0.717). However, among those who decided to view at least one solution, higher implicit growth mindset predicted higher engagement in learning in terms of time spent on looking at the solutions, while controlling for self-efficacy (Table 2). Furthermore, replicating the results of Study 1, a higher implicit growth mindset was associated with increased number of solutions in the right-censored Poisson regression among those who decided to view at least one solution, when controlling for self-efficacy (Table 2). Thus, again, our preregistered hypotheses was fully supported.
The role of explicit growth mindset (exploratory analysis). As expected, the decision to view any solutions was not predicted by the implicit (OR = 0.97, 95% CI [0.45, 2.08], p = 0.947) or explicit (OR = 1.17, 95% CI [0.55, 2.50], p = 0.680) growth mindsets, when controlling for self-efficacy (OR = 1.01, 95% CI [0.60, 1.70], p = 0.972). Furthermore, contrary to the findings of Study 1, neither implicit (b = 0.85, 95% CI [-0.46, 2.15], p = 0.201) nor explicit growth mindset (b = 0.06, 95% CI [-1.25, 1.36], p = 0.934) predicted the time-based learning variable, when controlling for self-efficacy (b = 0.46, 95% CI [-0.43, 1.35], p = 0.308). However, implicit growth mindset (IRR = 1.11, 95% CI [1.03, 1.20], p = 0.009) predicted the number of solutions reviewed in the right-censored Poisson regression among those who reviewed at least one solution, even after controlling for explicit growth mindset (IRR = 1.04, 95% CI [0.95, 1.13], p = 0.414) and self-efficacy (IRR = 1.07, 95% CI [1.01, 1.13], p = 0.013). Contrary to our findings in Study 1, explicit growth mindset was predictive (IRR = 1.12, p < 0.001) only if we did not include implicit growth mindset in the model – once we included implicit growth mindset, the explicit effect was no longer significant. The relationship of implicit and explicit growth mindset is represented in Fig. 1.
