Individual differences in cognitive offloading: a comparison of intention offloading, pattern copy, and short-term memory capacity

Table 3 Results of the reliability analysis

Task/measure	Test–retest [95% CI]	Cronbach’s α [95% CI]		Split-half [95% CI]
Task/measure	Test–retest [95% CI]	Session 1	Session 2	Session 1	Session 2
Intention offloading task
Externalizing proportion	.70 [.54, .82]	.88 [.82, .91]	.91 [.87, .93]	.65 [.47, .78]	.77 [.63, .86]

Pattern copy task
Openings model window	.88 [.81, .93]	.95 [.94, .97]	.95 [.92, .97]	.86 [.78, .91]	.91 [.86, .95]
Duration first opening	.75 [.61, .84]	.95 [.93, .97]	.96 [.92, .98]	.74 [.60, .83]	.85 [.76, .90]

Trial duration	.82 [.72, .89]	.95 [.93, .97]	.94 [.93, .96]	.84 [.74, .90]	.84 [.76, .90]
Corsi blocks task
Capacity	.71 [.55, .82]	–	–	–	–

The Corsi blocks task was adaptive, so that responses within each session were not independent of each other. Thus, Cronbach’s α and split-half reliability were not calculated for this task
