The sample
164 participants from the University of Tartu and the University of Tallinn
- 93 of them filled out the personality questionnaire
- 150 completed both SB-IAT tests
- 104 completed the extraversion Standard IAT test
- 94 completed the neuroticisim Standard IAT test
Overview of the data
IAT results
The distirbution of IAT results:
The mean values of IAT tests:
| mean | sdandard deviation | |
|---|---|---|
| SB-IAT Neuroticism | -0.1 | 0.3 |
| SB-IAT Extraversion | 0.17 | 0.36 |
| Standard IAT Extraversion | 0.19 | 0.45 |
| Standard IAT Neuroticism | -0.49 | 0.36 |
The distribution of slef-report measures
The mean values of extraversion and neuroticsism:
| mean | sdandard deviation | |
|---|---|---|
| Extraversion | 0.24 | 0.34 |
| Neuroticsism | -0.22 | 0.38 |
Correlation between implicit and explicit measures
| Extraversion | Neuroticsism | |
|---|---|---|
| SB_IAT_N | -0.1213 | 0.1158 |
| SB_IAT_E | 0.1983 | -0.2467 |
| Standard_IAT_E | 0.5812 | -0.2644 |
| Standard_IAT_N | -0.1275 | 0.1781 |
Explicit extraversion was correlated with both extraversion implicit measures:
- with extraversion single block IAT (r = .19, p < 0.05)
- with extraversion Standard IAT (r = .58, p < 0.05)
Explicit neuroticisim wasn’t correlated with implicit neuroticisim measures, but there was a significant correlation with implicit extraversion measures:
- with extraversion single block IAT (r = -.24, p < 0.05)
- with extraversion Standard IAT (r = -.26, p < 0.05)
Correlation between explicit measures
How to explaine the results that implicit neuroticsim measures were correlated with implicit extraversion measures?
This can be explained by the fact that in our sample explicit extraversion and explicit neuroticisim were correlated (r = -.40, p < 0.05).
Correlations between different IAT variations
| SB_IAT_N | SB_IAT_E | Standard_IAT_E | Standard_IAT_N | |
|---|---|---|---|---|
| SB_IAT_N | 1 | -0.05 | 0.02 | -0.02 |
| SB_IAT_E | 1 | 0.15 | -0.29 | |
| Standard_IAT_E | 1 | -0.28 | ||
| Standard_IAT_N | 1 |
We expected do see correlations between implicit measures that measured the same construct:
- correlation between extraversion Stadnard IAT and extraversion SB-IAT
- correlation between neuroticism Stadnard IAT and neuroticism SB-IAT
There was no significant correlation between the IAT variations that measured the same construct.
But we found significant correlations between neuroticisim Standard IAT measure with the two extraversion IAT’s:
- extraversion Standard IAT (r = .28, p < 0.05)
- extraversion Single block IAT (r = .29, p < 0.05)
This too can be explained by the correlation between the two explicit measures.
Conclusion
We expected to see correlation between implicit and explicit measures. This was partially true:
- Extraversion Standard IAT and extraversion SB-IAT were correlated with explicit extraversion.
- Implicit neuroticisim measures didn’t show any correlation between explicit neuroticism.
We expected to see correlations between different types of IAT’s which measured the same construct. There was no correlation.
