Fractal Fluency: Processing of Fractal Stimuli Across Sight, Sound, and Touch.

People are continually exposed to the rich complexity generated by the repetition of fractal patterns at different size scales. Fractals are prevalent in natural scenery and also in patterns generated by artists and mathematicians. In this chapter, we will investigate the powerful significance of fractals for the human senses.

The effect of image fractal properties and its interaction with visual discomfort on gait kinematics.

Exposure to images of urban environments affords higher cognitive processing demands than exposure to images of nature scenes; an effect potentially related to differences in low-level image statistics such as fractals. The aim of the current study was to investigate whether the fractal dimensions of an abstract scene affect cognitive processing demands, using gait kinematics as a measure of cognitive demand. Participants (n = 40) were asked to walk towards different types of synthetic images which were parametrically varied in their fractal dimensions.

Speech Perception Training in Children: The Retention of Benefits and Booster Training.

Objectives: Speech perception training can be a highly effective intervention to improve perception and language abilities in children who are deaf or hard of hearing. Most studies of speech perception training, however, only measure gains immediately following training. Only a minority of cases include a follow-up assessment after a period without training.

Hearing Health Care Digital Therapeutics: Patient Satisfaction Evidence.

Purpose: A digital therapeutic is a software-based intervention for a disease and/or disorder and often includes a daily, interactive curriculum and exercises; online support from a professional versed in the treatment base; and an online support community, typically active as a social chat group. Recently, the Consumer Technology Association published revised standards for digital therapeutics (DTx) that stipulate that a DTx must be evidence based and founded in scientific evidence showing effectiveness and must be supported by evidence showing improved patient satisfaction and adherence to an intervention. The purpose of this study was to investigate whether a DTx could help older adults better adjust to their hearing loss and acclimate to new hearing aids.

Nature in motion: The tuning of the visual system to the spatiotemporal properties of natural scenes.

Natural scenes contain several statistical regularities despite their superficially diverse appearances (e.g., mountains, rainforests, deserts).
