In masking-pattern experiments, thresholds are commonly measured for a sinusoidal signal masked by a narrow-band noise as a function of the signal frequency. For a given spectral separation of signal and masker, beating between signal and masker may

Sensory sensitivity is typically measured using behavioural techniques (psychophysics), which rely on observers responding to very large numbers of stimulus presentations. Psychophysics can be problematic when working with special populations, such a

Flicker perception was investigated using two-alternative forced-choice detection and discrimination tasks with four different types of external noise: (1) broadband noise, (2) 5-Hz notched-noise--broadband noise with a 5-Hz band centered on the sign

Difficulties arise in measuring masking by Mach bands because very-low-contrast signals distort the bands. [J. Opt. Soc. Am. A 17, 1147 (2000).] Adding narrow luminance increments (bright bars) in the dark Mach band widens the dark band; adding decre

An urban population sample of 40 to 79-year-old men and women was investigated to evaluate the influence of age and activity level on muscle strength and endurance and to establish a reference material. During the investigation 144 persons were teste

In 11 female patients with Fibromyalgia Syndrome (FS), biopsies from the m. vastus lateralis were analyzed, in order to reveal any possible changes which might explain muscular weakness and fatigue. Nineteen healthy subjects served as a control group

Analysis of motion may be accomplished using the spatiotemporal variations produced when a spatially varying luminance waveform moves across linear receptive fields. Moving contrast-modulated patterns which consist of coarse-scale spatial variations

Nine men, 78–84 yr of age, participated in a dynamometer training program 2–3 times/wk, totaling 25 sessions, using voluntary maximal isometric, concentric, and eccentric right knee–extension actions (30 and 180 degrees/s). Measurements of musc
