Questionable research practices (QRPs) pose a significant threat to the integrity and credibility of scientific research. However, historically, they remain ill-defined comprehensive list QRPs is lacking. The article addresses this concern by defining, collecting, categorizing using an expert consensus method. Collaborators study agreed on following definition: “Questionable are ways producing, maintaining, sharing, analyzing, or interpreting data that likely produce misleading conclusions,...
Abstract The nocebo effect, the evil twin of better-known placebo effect in which anticipation harm causes that harm, is increasingly thought to be responsible for poor clinical outcomes. In humans, hyperalgesia (i.e., increased sensitivity pain) blocked by proglumide, a cholecystokinin (CCK) receptor antagonist. Yet neural circuitry underlying remains unidentified, largely due lack appropriate animal models. Independently, our two laboratories developed unique models CCK-dependent...
In psychological science, replicability—repeating a study with new sampleachieving consistent results (Parsons et al., 2022)—is critical for affirming the validity of scientific findings. Despite its importance, replication efforts are few and far between in science many attempts failing to corroborate past This scarcity, compounded by difficulty accessing data, jeopardizes efficient allocation research resources impedes advancement. Addressing this crucial gap, we present Replication...
Placebo effects relieve various somatic symptoms, but it is unclear how they can be enhanced to maximize positive treatment outcomes. Oxytocin administration may potentially enhance placebo effects, few studies have been performed, and had conflicting findings. The study aim was investigate the influence of verbal suggestions oxytocin on expectations for pain itch.One hundred eight female participants were allocated one following four groups: (1) with suggestions, (2) (3) without (4)...
Placebo and nocebo effects—beneficial or adverse outcomes driven by expectations rather than active treatment components—are well documented in domains such as pain, mental health disorders, fatigue etc. However, their influence on food metabolism food-related behaviors remains underexplored. This study investigated whether verbal suggestions about the effects of a sham vagus nerve stimulation could alter hunger, craving, desirability, choice healthy volunteers. In randomized, single-blind,...
Oxytocin has been shown to increase trust, decrease anxiety, and affect learning as observed in conditioning paradigms. Trust, are important factors that influence placebo effects. In this study, we investigated whether oxytocin can analgesia, nocebo hyperalgesia, extinction processes of both. Eighty male volunteers were assigned a 40 IU nasal spray group, or control group. Placebo analgesia hyperalgesia induced by procedure combination with verbal suggestions. The results demonstrate the...
Implicit gender biases (IGBs) are unconscious evaluations about a person based on gender. IGBs of healthcare providers may affect medical decision making. This study investigated whether and genders patients general practitioners (GPs) influence diagnostics treatment decisions in the context diabetes type 2.Ninety-nine GPs participated this randomized online study. Associations Tasks were used to measure two IGBs, related lifestyle (women have healthier than men) communication (men less...

It has been demonstrated that secretion of several hormones can be classically conditioned, however, the underlying brain responses such conditioning have never investigated before. In this study we aimed to investigate how oxytocin administration and conditioned influence responses. total, 88 females were allocated one three groups: administration, oxytocin, or placebo, underwent an experiment consisting acquisition evocation days. Participants in group received 24 IU together with a...
eHealth interventions have the potential to increase physical activity of users. However, their effectiveness varies, and they often only short-term effects. A possible way enhancing is positive outcome expectations users by giving them suggestions regarding intervention. It has been shown that when individuals various types interventions, tend benefit from these more.The main objective this web-based study investigate whether can change participants a smartphone intervention subsequently...
Three ways of achieving happiness—life pleasure, life engagement, and meaning (Seligman, 2002)—have been examined among adult samples. However, very few studies have investigated these orientations to happiness in non-adult populations. Numerous found that different spending leisure time affect the psychological well-being adolescents. Bringing two perspectives together, aim present study is identify extent which are related choice activities a sample adolescents from eight European countries.
Contagious itch can be evoked by observing people scratching. Verbal suggestions about to-be-received influence intensity, as shown placebo research, but it is unknown whether this extends to contagious itch. The current study aimed replicate prior findings that listening scratching and rubbing sounds elicits itch, investigate modulate process. Healthy participants (n = 140) received positive or negative in response the (aimed decrease increase expected respectively), no specific a control....
ABSTRACT Objective There is evidence that placebo effects may influence hormone secretion. However, few studies have examined in the endocrine system, including oxytocin effects. We studied whether it possible to trigger using a classical conditioning paradigm. Methods Ninety-nine women were assigned conditioned, control, or drug control group. In two-phase paradigm, participants conditioned and groups received an nasal spray combined with distinctive smell (conditioned stimulus [CS]) for...
In an attempt to improve reproducibility, more attention is being paid potential sources of stress in the laboratory environment. Here, we report that mere proximity pregnant or lactating female mice causes olfactory-mediated stress-induced analgesia, a variety noxious stimuli, gonadally intact male mice. We show exposure volatile compounds released urine and can themselves produce associated pain inhibition. This phenomenon, novel form female-to-male chemosignaling, mediated by scent...
Several studies have demonstrated that in the mental health domain, experience does not always lead to better diagnostic decisions, suggesting clinical psychology experience-based intuition might actually improve performance. The aim of current study was investigate differences preferred reasoning styles novice and experienced psychologists as possible explanation this surprising phenomenon. We investigated control decisions (n = 20) well age-matched controls 20 n respectively) by using...

ABSTRACT Objective The objective of this study was to investigate whether placebo effect induced by pharmacological conditioning with intranasal insulin can affect glucose, insulin, C-peptide, hunger, and memory in patients diabetes type 2 healthy controls. Methods Placebo conditioning. Thirty-two older (mean age = 68.3 years) age- sex-matched thirty-two adults 67.8 were randomly assigned a conditioned or control group. On day 1, group received six administrations stimulus (CS; smell...
Negative expectations can increase pain sensitivity, leading to nocebo hyperalgesia. However, the physiological and psychological factors that predispose individuals this phenomenon are still not well understood. The present study examined whether stress induced by a social stressor affects hyperalgesia, effect is mediated self-reported responses. We recruited 52 healthy participants (15 men) who were randomly assigned either Trier Social Stress Test (TSST) or control condition (a friendly...
