Table 3.
Associations between eye movement types (contrasted with the absence of eye movements) and behavioural measures.
| Dependent variables | Eye movements (EMs) effect (versus no EMs) | |||||
|---|---|---|---|---|---|---|
| Slow EMs | Isolated REMs | REM bursts | ||||
| OR [CI] | P | OR [CI] | P | OR [CI] | P | |
| Neutral emotional behaviours | 1.4 [1.2–1.6] | 0.004 | 2.8 [2.5–3.1] | < 0.0001 | 4.6 [4.2–5.1] | < 0.0001 |

| Negative versus positive emotional behaviours | – | – | 1 [0.5–2] | > 0.05a | 3.5 [2–6] | < 0.0001a |
P values are presented after Bonferroni type corrections.
EMs eye movements, SEMs slow eye movements, REMs rapid eye movements, OR odds ratio, CI 95% confidence interval.
aA mixed logistic regression model could not be used because too few mini-epochs presented a combination of the contrasts of eye movements and behaviours used, a chi-square test was used.
