High impact information on Psychophysics

• Since the perception of noxious stimuli has never been studied in ICD, we performed a controlled study to obtain more insight into the psychophysics of dystonia-related muscle pain by evaluating pressure-induced pain levels [1].
• James Daniel Hardy (1904-1985). Tribute to a pioneer in pain psychophysics [2].
• This model naturally produces the curvilinear accumulation of neural activity introduced to timing psychophysics by Miall (Models of Neural Timing, Elsevier Science, 1996), and implicated in Parkinsonian timing by Malapani and Rakitin (Functional and Neural Mechanisms of Interval Timing, CRC Press, 2003) [3].
• In a CRT simulation of the "edge-substitution" paradigm [Gilchrist (1988) Perception & Psychophysics, 43, 415-424], observers adjusted the apparent reflectance (lightness) of a test surface to match incremental or decremental standards [4].
• The new model is consistent with previous human psychophysics and has the emergent property that its output detectors have similar response properties to neurons in area MST [5].

Biological context of Psychophysics

• Examples are given covering the determination of spatial contrast sensitivity in monkeys exposed to methyl mercury as an example of visual psychophysics, and the assessment of vibration sensitivity in monkeys exposed to acrylamide, as an example of somatosensory psychophysics [6].

Associations of Psychophysics with chemical compounds

• CONCLUSIONS AND SIGNIFICANCE: The results suggest that covariation between ECAP thresholds and psychophysics plays a decisive role in the relationship of ECAP threshold with T-, but not with C-level [7].
• Further studies investigating the influence of long-term treatment on cortical excitability and psychophysics may therefore provide deeper insight into a possible therapeutical efficiency of fluoxetine in poststroke patients [8].
• Integration psychophysics was used to explore the taste perception of mixtures of sucrose, fructose, and citric acid [9].

Gene context of Psychophysics

• Psychophysics detected a slightly more pronounced affection of the rod system compared to the cone system in both the hemizygous males and the carrier with the deletion of the RPGR gene and the first exon of the SRPX gene [10].
• Psychophysics of reading. XVII. Low-vision performance with four types of electronically magnified text [11].
• The perceived direction of rotation of a 3-D cloud of dots can be biased by a prior rotation (Jiang, Pantle, and Mark, 1998 Perception & Psychophysics 60 275-286) [12].
• However, Pentland (1980, Perception & Psychophysics, 28, 377-379) found his own maximum likelihood method (Best PEST) to be considerably less variable than the standard staircase [13].
• In recent years, novel classes of stimuli such as "drift-balanced" or "theta" motion (in which the picture elements carrying luminance contrast do not move, or move in the opposite direction to the traveling object defined by such element motion) were introduced into psychophysics [14].

Analytical, diagnostic and therapeutic context of Psychophysics

• Calibrated LCD/TFT stimulus presentation for visual psychophysics in fMRI [15].
