Schizotypy and perceptual span in a non-clinical sample: a virtual reality study

Figures & data

Figure 1. Image of the virtual reality task.

Note: This image is taken from the game view of the Unity editor.

Figure 2. Task procedure.

Note: An example of the one-up, two-down staircase procedure. The lateral separation of the stimuli is increased following correct responses (frames 1 and 3) and reduced twice as much after an incorrect response (frame 5). Trials are separated by a one second break screen. Time runs from the top-left to the bottom-right of the figure.

Figure 4. The distribution of perceptual span across participants.

Figure 5. Regression analysis between Schizotypy scores and Perceptual Span.

Note: Perceptual span is expressed in degrees of lateral separation between the stimuli.

Figure 6. Scatter plot of the relationship between the two Schizotypy factors of cognitive/perceptual deficits and disorganisation.

Note: Scores are indicative of each participant’s Schizotypy score, with the questions separated into the two associated factors.

	Cognitive/Perceptual factors	Interpersonal deficits	Disorganisation
Cognitive/Perceptual Factors		0.73***	0.58***
Interpersonal Deficits	0.73***		0.64***
Disorganisation	0.58***	0.64***
Perceptual Span	−0.27*	−0.21	−0.26

Note: *p > 0.05, **p > 0.01, ***p > 0.001.
