Elżbieta A. Bajcar; Wacław M. Adamczyk; Karolina Wiercioch-Kuzianik et al.

PLOS ONE, Vol. 15 No. 5 · 2020 · English · PLOS Scopus

Influential theoretical accounts take the position that classical conditioning can induce placebo effects through conscious expectancies. In the current study two different conditioning procedures (hidden and open) were used to separate expectancy from conditioning in order to reveal the role of…

Pain rewarded: hyperalgesic and allodynic effect of operant conditioning in healthy humans—protocol for a systematic review and meta-analysis

Wacław M. Adamczyk; Kerstin Luedtke; Ewa Buglewicz et al.

Systematic Reviews, Vol. 7 No. 1 · 2018 · English · DOAJ Scopus

Abstract Background ‘Pain rewarded’ is a hypothesis wherein acute pain sufferers are exposed to reinforcers and punishers from their environment that shape their behaviour, i.e. pain responses. Such a point of view has been taken for granted by many clinicians and researchers although existing…

Pain inhibition is not affected by exercise-induced pain

Tibor M. Szikszay; Waclaw M. Adamczyk; Ewa Wojtyna et al.

PAIN Reports, Vol. 5 No. 2 · 2020 · English · DOAJ Scopus

Abstract. Introduction:. Offset analgesia (OA) and conditioned pain modulation (CPM) are frequently used paradigms to assess the descending pain modulation system. Recently, it was shown that both paradigms are reduced in chronic pain, but the influence of acute pain has not yet been adequately…

One of us or one of them? The effects of the model’s and observer’s characteristics on placebo analgesia induced by observational learning

Elżbieta A. Bajcar; Karolina Wiercioch-Kuzianik; Dominika Farley et al.

PLOS ONE, Vol. 15 No. 12 · 2020 · English · PLOS Scopus

Previous studies have proved that observational learning can induce placebo analgesia, but the factors that influence observationally induced placebo analgesia have not yet been extensively examined. The primary goal of this study was to investigate the effect of information about the role that the…

Technology and Electrophysical Properties of the (K0.44Na0.52Li0.04) NbO3 Ceramics Doped by Cr3+, Zn2+, Sb3+ or Fe3+

D. Bochenek; K. Osińska; P. Niemiec et al.

Archives of Metallurgy and Materials, Vol. vol. 63 No. No 3 · 2018 · English · DOAJ

In the work five ceramic compounds based on the (K0.44Na0.52Li0.04)NbO3 (KNLN) material modified with oxides: Cr2O3, ZnO, Sb2O3 or Fe2O3 (in an amount of 0.5 mol.%) were obtained. The KNLN-type composition powder was prepared by solid phase synthesis from a mixture of simple oxides and carbonates…

Psychological mechanisms of offset analgesia: The effect of expectancy manipulation

Tibor M. Szikszay; Waclaw M. Adamczyk; Janina Panskus et al.

PLOS ONE, Vol. 18 No. 1 · 2023 · English · PLOS Scopus

A frequently used paradigm to quantify endogenous pain modulation is offset analgesia, which is defined as a disproportionate large reduction in pain following a small decrease in a heat stimulus. The aim of this study was to determine whether suggestion influences the magnitude of offset analgesia…
