“…Helson’s (1964) ALT has been widely used in sensory perception and psychophysics to explain magnitude adjustments to context (Murch, 1973; Coren and Ward, 1989; Gescheider, 1997). Adaptation level effects and similar “differential contextual effects” (Marks and Arieh, 2006) have been demonstrated in perception of: touch, taste, olfaction (Marks and Arieh, 2006), pain (Rollman, 1979; Kyle et al, 2009), weight (Helson, 1948), temperature (Masuyama, 1994), loudness (Marks, 1994), vision (Helson, 1964), phobias (Lauterbach, 1979), and even market research (Della Bitta and Monroe, 1974). There are a number of overlapping terms to describe change in perception with repeated exposure including acclimatization, adaptation, stimulus failure, fatigue as well as habituation (Helson, 1964; Mazess, 1975; McBurney and Balaban, 2009).…”

Models of tinnitus suggest roles for auditory, attention, and emotional networks in tinnitus perception. A model of tinnitus audibility based on Helson’s (1964) adaptation level theory (ALT) is hypothesized to explain the relationship between tinnitus audibility, personality, memory, and attention. This theory attempts to describe how tinnitus audibility or detectability might change with experience and context. The basis of ALT and potential role of auditory scene analysis in tinnitus perception are discussed. The proposed psychoacoustic model lends itself to incorporation into existing neurophysiological models of tinnitus perception. It is hoped that the ALT hypothesis will allow for greater empirical investigation of factors influencing tinnitus perception, such as attention and tinnitus sound therapies.

“…As might be expected from a group of participants capable of perceiving weight differences, an overall difference between responses to the heavy and light weight were observed. There was a shorter latency to threshold and tolerance under the heavy weight (1000 g) relative to the light weight (500 g), which is consistent with other pressure algometer literature (Kyle, McNeil, Weinstein, & Mark, 2009). The possibility that weights were perceived differently because of finger presentation (middle or ring) cannot be ruled-out as a confound, however, because weights were consistently applied to the same finger (although evenly across hands) in this work.…”

“…Known order effects of weight presentation in pressure algometer literature are related to perception of the lighter weight. Specifically, tolerance latency is shorter for the light weight when it is presented after a heavy weight than when it is presented after another light weight (Kyle et al, 2009). Effects of order were not observed for the heavy weight in the same study.…”

“…The possibility that weights were perceived differently because of finger presentation (middle or ring) cannot be ruled-out as a confound, however, because weights were consistently applied to the same finger (although evenly across hands) in this work. Concern for different weight perception across ring, middle and index fingers is not evident among literature specific to the pressure algometer utilized here, although other work did utilize a counter-balanced exposure across test fingers (comparing either middle and index or middle and ring fingers after an initial exposure to weight on either the ring or index finger, respectively; Kyle et al, 2009). Regardless of whether the difference between weights observed here was the result of finger placement or the ability to discern between weights, the premise that participants respond differently to the algometer task under different testing circumstances was corroborated and any effects of this difference on algometer outcome variables was accounted for by including it as a factor in subsequent assessments of threshold and tolerance.…”

“…This outcome was not supported, leaving the first interpretation as the most plausible. Extant pressure algometer literature tends to average across, rather than explicitly evaluate, differences that might exist across hands of participants (Kyle et al, 2009;Vowles, McNeil, Sorrell, & Lawrence, 2006).…”

Effects of Systematic Sleep Fragmentation on Tolerance and Threshold in a Pressure Pain Task: Associations with Sustained Attention

Purpose: Pain is amplified following partial sleep deprivation. Pain has not been evaluated after sleep interruption, when total sleep time is preserved. Sleep interruption, also called sleep fragmentation, is ecologically relevant because it is caused by common sleep disorders such as Obstructive Sleep Apnea [OSA], Upper Airway Resistance Syndrome [UARS] and Periodic Limb Movements Disorder [PLMD]. The Sleep Continuity Hypothesis posits that the restorative effects of sleep are related to sleep quality in addition to quantity. With this study, my goal was to evaluate whether sleep fragmentation affected pain threshold and/or tolerance by systematically fragmenting the sleep of otherwise healthy adults. Methods: Twelve adult female participants without chronic pain or evidence of a sleep disorder underwent a 14-day protocol. Sleep was monitored using actigraphy throughout the study. Participants completed daily morning and evening reaction time tasks to evaluate changes in attention. To measure changes in pain threshold (when a stimulus becomes painful) and tolerance (when a stimulus is no longer tolerable), a pressure-pain task was administered in-lab by a researcher. This test occurred a total of eight times, morning and evening. Participants spent the eighth, ninth and 13th nights in-lab. Night eight was for acclimatization to the research facility [BASE]. To compare pain after experimental sleep fragmentation (every five minutes; [FRAG]) with pain after sham [SHAM], these conditions were assigned pseudo-randomly to nights nine and 13. Three nights of recovery sleep outside the lab occurred between SHAM and FRAG nights. Results: Sleep interruptions were induced at a rate of 5.2 times per hour, on average, without changing participants' total sleep time. Stage two sleep proportion was higher on fragmentation night. Lapses in vigilance were lower after BASE than other nights. The slowest 10% of reaction times were slower after SHAM than BASE. Overall, reaction time did not reliably differ as a result of fragmentation. Neither pain threshold nor pain tolerance differed as a function of experimental condition. Conclusions: Systematic sleep fragmentation, particularly of stage two sleep, did not affect reaction time (a measure of sustained attention) or pressure pain (threshold or tolerance). Reaction time was not related to individual-level changes in fragmentation or pain. Future work should aim to establish the minimal fragmentation that engenders a clinical effect (without concomitant hypoxemia) to inform clinical definitions of fragmentation severity.

Touch-induced pupil size reflects stimulus intensity, not subjective pleasantness

et al. 2018

Interpersonal touch is known to influence human communication and emotion. An important system for interpersonal touch is the C-tactile (CT) system, which is activated by a soft stroke on hairy skin with a velocity of 1–10 cms −1 . This system been proposed to play a unique role in hedonic valence and emotion of touch. For other sensory modalities, hedonic processing has been associated with pupil dilation. However, it is unclear whether pupil dilation can be modulated by hedonic touch. The current study investigated in two experiments how pupil size reacts to both affective and non-affective stroking. Pupil-size data were obtained to investigate differences between stroking conditions. In addition, an adjusted version of the Touch Perception Task (TPT) was used to assess subjective touch pleasantness ratings. In Experiment 1, affective (3 cms −1 ) and non-affective (0.3 and 30 cms −1 ) stroking was applied to the dorsal side of the right hand. Results revealed that stroking velocity had a significant effect on TPT-item scores, showing higher that affective touch was rated as more pleasant compared to non-affective touch, thereby replicating the previous studies. Results, however, revealed no specific pupil dilation for the 3 cms −1 condition; instead, a logarithmic relation was found between pupil-size dilation and stroking velocity. This relation was confirmed in a second experiment. Furthermore, the palm of the hand was used as a control site for tactile stimulation, for which similar findings were obtained as for the dorsal side of the hand. In addition, skin conductance recordings showed a pattern of response to different stroking velocities similar to pupil dilation. These results suggest that pupil-size dilation does respond to tactile input, but that this response is related to arousal caused by changes in stimulus intensity (e.g., stroking velocity) rather than specific C-tactile stimulation.
