Color preferences in participants with high or low hypnotic susceptibility

Figures & data

Figure 1 Color preference orders in the HIGH (rhombus, n=70) and LOW (square, n=66) groups.

Notes: *p<0.05 vs HIGH group. HIGH group consisted of participants with higher hypnotic susceptibilities; LOW group consisted of participants with lower hypnotic susceptibilities.

Table 1 Distribution of participants who passed the SHSSC test in the two groups of participants

SHSSC item	Number, rate, %		χ^2
	HIGH (n=70)	LOW (n=66)
Hand lowering	61, 87.1	22, 33.3	41.4
Moving hands apart	65, 92.9	17, 25.8	63.9
Mosquito hallucination	64, 91.4	14, 21.2	68.5
Taste hallucination	62, 88.6	13, 19.7	65.1
Arm rigidity	64, 91.4	15, 22.7	65.9
Dream	42, 60.0	3, 4.5	47.2
Age regression	67, 95.7	36, 54.5	31.3
Arm immobilization	63, 90.0	4, 6.1	95.8
Anosmia to ammonia	37, 52.9	5, 7.6	32.6
Hallucinated voice	21, 30.0	3, 4.5	15.1
Negative visual hallucination	47, 67.1	5, 7.6	51.0
Posthypnotic amnesia	21, 30.0	1, 1.5	20.3

Notes: All p-values <0.01 vs LOW group. HIGH group consisted of participants with higher hypnotic susceptibilities; LOW group consisted of participants with lower hypnotic susceptibilities.

Table 2 Stepwise multiple regression among color preferences and the SHSSC items in the HIGH (n=70) and LOW (n=66) groups

Group	Color preference	SHSSC predictor	Adjusted R^2	β	SE	p-value	95% CI
HIGH	Black	Taste hallucination	0.12	−0.31	1.06	0.008	−5.02 to −0.80
		Arm rigidity		0.25	1.20	0.033	0.21–5.01
HIGH	White	Arm rigidity	0.05	0.24	1.05	0.042	0.08–4.26
HIGH	Brown	Anosmia to ammonia	0.07	0.29	0.54	0.014	0.29–2.46
HIGH	Pink	Posthypnotic amnesia	0.04	−0.24	0.76	0.046	−3.05 to −0.03
HIGH	Yellow	Posthypnotic amnesia	0.11	0.30	0.66	0.012	0.38–3.00
		Taste hallucination		0.27	0.94	0.023	0.32–4.08
HIGH	Purple	Negative visual hallucination	0.07	−0.29	0.64	0.015	−2.87 to −0.32
LOW	Blue	Moving hands apart	0.06	0.28	0.79	0.025	0.24–3.41

Notes: HIGH group consisted of participants with higher hypnotic susceptibilities; LOW group consisted of participants with lower hypnotic susceptibilities.
