- The ability to think abstractly constitutes a fundamental dimension of human cognition. Although abstraction has been extensively studied, its emotional and affective antecedents have been largely overlooked. One experiment was conducted to examine whether physical pain affects abstraction. Drawing on Construal Level Theory [Trope, Y., & Liberman, N. (2010). Construal-level theory of psychological distance. Psychological Review, 117, 440–463] and Loewenstein’s [(1996). Out of control: Visceral influences on behavior. Organizational Behavior and Human Decision Processes, 65, 272–292] visceral factors theory, we hypothesised that pain impairs abstraction because pain constricts people’s mental horizons and lead to a concrete, inward-focus toward oneself in the here and now. Physical pain was manipulated between subjects (N = 150). The participants either kept their left hand immersed in cold (painful) water or neutral (painless) water while we measured abstract versus concrete behaviour identification, categorisation, and perceptual processing. Bayesian statistical analyses indicate substantial evidence against the hypothesis that pain impairs abstraction. In contrast to many other previously studied cognitive outcomes (e.g. attention), abstraction appears to be largely immune to acute, experimentally induced pain.

- Background: The ability to traverse psychological distance by going beyond the experienced reality of the self, here and now, is fundamental for effective human functioning. Yet, little is known about how physical pain affects transcendence of psychological distance. Using a construal level theory framework of psychological distance, the current research examines the hypothesis that pain impairs people's ability to traverse any kind of psychological distance whether it be temporal, social, and spatial distance, or the hypothetical. Methods: Using the cold pressor test, 151 participants participated in an experiment where they were either induced with acute pain (treatment group) or no pain (control group) while completing a battery of questions measuring to what extent their current thoughts were transcending psychological distance. Results: The results were largely consistent with the hypothesis. Relative to the control group, pain induced participants showed significantly less transcendence of past temporal distance, social distance, spatial distance, and the hypothetical. Furthermore, greater self-reported pain intensity was significantly associated with less transcendence of temporal (past and future), social, and spatial distance. Conclusion: Physical pain impairs the ability to traverse psychological distance. The research has practical implications for the pain clinic and for pain-afflicted individuals in everyday life.

- Objectives. FM is a condition that preferentially affects women. Sex hormones, and in particular oestrogens, have been shown to affect pain processing and pain sensitivity, and oestrogen deficit has been considered a potentially promoting factor for FM. However, the effects of oestrogen treatment in patients suffering from FM have not been studied. Here, we examined the effect of transdermal oestrogen substitution treatment on experimental as well as self-estimated pain in women suffering from FM.Methods. Twenty-nine post-menopausal women were randomized to either 8 weeks of treatment with transdermal 17β-oestradiol (50 µg/day) or placebo according to a double-blind protocol. A self-estimation of pain, a set of quantitative sensory tests measuring thresholds to temperature, thermal pain, cold pain and pressure pain, and a cold pressor test were performed on three occasions: before treatment, after 8 weeks of treatment and 20 weeks after cessation of treatment.Results. Hormonal replacement treatment significantly increased serum oestradiol levels as expected (P < 0.01). However, no differences in self-estimated pain were seen between treatment and placebo groups, nor were there any differences between the two groups regarding the results of the quantitative sensory tests or the cold pressor test at any of the examined time points.Conclusion. Eight weeks of transdermal oestradiol treatment does not influence perceived pain, pain thresholds or pain tolerance as compared with placebo treatment in post-menopausal women suffering from FM.

- We examined the relationship between estrogen and pain in women undergoing in vitro fertilization (IVF). Quantitative sensory tests (QST) were performed twice during the IVF-regimen: once during hormonal down-regulation and once during hormonal upregulation. A group of healthy men and a group of women using monophasic contraceptives were also examined, to control for session-to-session effects. Among the women undergoing IVF, serum 17β-estradiol levels differed strongly between treatments as expected, and increased from 65.7 (SD = 26) pmol/l during the downregulation phase, to 5188 (SD = 2524) pmol/l during the up-regulation phase. Significant outcomes in the QST were only seen for temperature perception thresholds (1.7°C vs. 2.2°C; P = 0.003) and cold pain threshold (11.5°C vs. 14.5°C; P = 0.04). A similar change in cold pain threshold was also seen in the two control groups, however, and statistical analysis suggested that this change was due to a session-to-session effect rather than being the result of hormonal modulation. Heat pain thresholds, heat tolerance, pressure pain thresholds, and the cold pressor test showed no significant differences between sessions. These data demonstrate that pain perception and pain thresholds in healthy women show little, if any, changes even with major variations in serum estradiol levels.

- The role of gonadal hormones on pain sensations was investigated in normally menstruating women (n = 16) using the cold pressor test. Tolerance time, pain threshold, and pain intensity were examined once a week during a 4-wk period, and serum concentrations of 17β-estradiol and progesterone were determined at each test session, which were classified into the early follicular phase, late follicular phase, early luteal phase, and late luteal phase, as determined by the first day of menses and the actual hormone levels recorded. A group of men (n = 10) of the same age interval was examined for comparison. The data show that pain threshold was reduced during the late luteal phase compared with the late follicular phase, and hormone analyses showed significant positive correlation between the progesterone concentration and lowered pain threshold and increasing pain intensity. Hormone analysis also showed an interaction between S-estradiol and S-progesterone on pain intensity, demonstrating that the increased perceived pain intensity that was associated with high progesterone concentrations was significantly reduced with increasing levels of estradiol. While no statistically significant sex differences in pain measurements were found, women displayed much more pronounced, and statistically significant, session-to-session effects than men, with increased pain threshold and decreased pain intensity with each test session. Hence, these data suggest that the changes in the serum concentration of gonadal hormones that occur during the menstrual cycle influence pain sensations elicited by noxious tonic cold stimulation and show that adaptation to the cold pressor test may be sex dependent. © 2007 the American Physiological Society.
