GLMM results of full model – Influence of Search extension variable and other sources of task difficulty on solution time, accuracy and search.
| Random effects: | Solution time |
Accuracy |
Search |
|---|---|---|---|
| variance (SD) | variance (SD) | variance (SD) | |
| Item (Intercept) | .0001 (.008) | 0.501 (.71) | .00 (.00) |
| Subject (Intercept) | .0001 (.011) | 0.277 (.53) | .66 (.81) |
| Fixed effects: | ß (SE) | t-value | ß (SE) | z-value | ß (SE) | z-value |
|---|---|---|---|---|---|---|
| Intercept | .072 (.02) | 4.40** | 2.04 (1.11) | 1.83 | -.98 (.29) | −3.32** |
| Search extension | -.057 (.01) | −5.88** | −4.55 (0.70) | −6.49** | .34 (.22) | 1.55 |
| Target words | .053 (.03) | 2.14* | 2.77 (1.71) | 1.62 | -.41 (.38) | −1.09 |
| Prime | -.026 (.01) | −2.82* | −0.99 (0.62) | −1.58 | .06 (.21) | 0.26 |
| RT | .04 (.00) | 26.75** |
Note. Significance codes: 0.001 ’**’, 0.05 ’*’, ß = standardized mean estimates; standard errors (SE) or standard deviation (SD) is given in parenthesis. Prime = cosine distance between prime (dew) and solution (rain); Target words = mean cosine distance between all three target words per item (drop, coat, proof) and solution; Search extension = cosine distance between prime compound (dewdrop) & solution compound (raindrop). Random and fixed effects for solution time and accuracy are depicted for the full model. For search these effects are depicted for the full model + RT, see Table 1a. Note, because solution time was modeled via a Gamma function with an inverse link function, the signs of the respective fixed effects are inverted.
