To measure subjective mood, we used a Visual Analog Scale (VAS) comprised of 13 adjectives rated on a 1–100 (not at all–extremely) line. Unsurprisingly, given the strong and relatively identifiable subjective effects of MDMA, most participants correctly identified it, especially at the high dose, as a stimulant drug.

, 2012 ). Rejestracja: 2013 Użytkownik nieaktywny Płeć: chłopak . = 4.2), with some college education (mean = 14.8 years, s.d. Task order was counterbalanced in both studies to minimize any order effects.

It would be particularly interesting for future studies in laboratory animals to examine the effects of MDMA on the incentive value of non-social vs social rewards. Although IAPS pictures are not normatively rated for social relevance, based on previous research ( Cacioppo et al. These effects may also contribute to the abuse of this unusual stimulant drug, given that MDMA users report that such prosocial effects motivate MDMA use. MDMA consistently reduces the ability to identify negative emotional expressions in others ( Bedi et al. Nie akceptujemy zachowań, First, the relatively homogeneous sample, which excluded DSM-IV disorders and heavier drug users, may limit our ability to detect reinforcing effects of the drug, which may be more evident in ‘at risk’ populations. These findings of increased positive responses to pleasant pictures with social content are consistent with the idea that MDMA increases positive responses to social stimuli. Healthy participants (58 male, 43 female), ages 18–35 were recruited through flyers and online advertisements. (2010) found to be sensitive to the unique effects of MDMA on social emotions, and two typical stimulant-like effects ‘elated’ and ‘stimulated’.

, 2007 ; Dumont et al. MDMA increased positive responses to pleasant pictures with social content, while decreasing positive responses to pleasant pictures without social content. Although these were the minimum requirements for compliance, typical abstention times for recreational drugs were longer. Nie stosując się do niego, możesz stracić konto. , 2002 ; Bedi et al. We counterbalanced picture set with drug dose, such that each picture set was paired approximately the same number of times with each drug dose. , 2005 ; Thompson et al. , 2013 ), although here we saw a change in positivity ratings rather than arousal. , 2008 ), comparatively little is known about which basic emotional processes the drug alters to produce these effects.

We investigated the effects of oral MDMA (0, 0.75 and 1.5 mg/kg) on reactivity to emotionally positive, negative and neutral pictures with or without social content, in occasional MDMA users ( N = 101). , 1988 ; Lin et al. Conversely, MDMA impairs recognition of negative states such as expressions of anger or fear ( Bedi et al. , 2012a , in press ). = 572.75, t (98) = 5.78, P < 0.001, linear drug effect on elated B = 5125.84, s.e.

This is the question addressed here. The MDMA doses used also produced typical changes in both subjective and cardiovascular measures, including increased positive and prosocial feelings, and increased blood pressure, indicates our doses were effective in producing the typically reported subjective effects of MDMA.

Valium), 4. At 10:00 am and every 30–60 min thereafter, subjective and cardiovascular effects were assessed. , 2011 ) of the R statistical computing environment (v. 2.15.2; R Development Core Team, 2011 ) as our primary statistical approach.

We used linear mixed effect models (LMEMs) in the lme4 package (v 0.999999-0; Bates et al. = 604.9, t (98) = 1.98, P = 0.05, respectively], but effects of MDMA did not differ across studies in the AUC analysis (which accounts for baseline levels of loving and elated).

It is unknown whether SSRIs act more strongly on social stimuli vs non-social stimuli.

IAPS pictures are normatively rated on valence (positivity vs negativity) and arousal. , 2013 ) in a previous study in healthy volunteers. We constructed 3 sets of 54 pictures for Study 1, with 9 pictures per subtype per set, and 4 sets of 36 pictures for Study 2, with 6 pictures per subtype per set 1 .

At the end of each session, we asked participants to identify the class of drug that they thought they had received that day as ‘1. This phenomenon appears likely to contribute to the unique ‘entactogenic’ effects of MDMA by increasing the comparative value of social contact and closeness with others. In each of these comparisons, it should be noted that there are potential dose equivalency issues. Receive exclusive offers and updates from Oxford Academic.

The measures reported here were the only measures shared between the two studies; thus, additional results from these studies are published separately elsewhere ( Kirkpatrick et al. Finally, it has often been proposed that the oxytocin release triggered by MDMA is responsible for its prosocial effects ( McGregor et al.

The neuropharmacological mechanisms underlying the observed effects of MDMA on responses to social stimuli are not known. Serotonin and emotional processing: does it help explain antidepressant drug action? się z innymi członkami społeczności, a poza tym zniknie też There is also evidence that MDMA releases oxytocin, a neuropeptide involved in affiliative behaviors ( Dumont et al. , 2012a ), and increases the degree of arousal reported in response to pictures of people in positive emotional situations ( Hysek et al. Both Good Play and Bad Play. In conclusion, we observed for the first time that MDMA has a ‘socially selective’ effect in humans, whereby it increases the reward value of positive social stimuli, while decreasing the value of non-social positive stimuli.

A sedative (e.g. Nevertheless, MDMA appears to have a unique profile of effects on responses to emotional stimuli when compared to related drugs at typically used doses. , 1998 ). We hypothesized that the drug would dose-dependently increase reactivity to positive emotional stimuli and dampen reactivity to negative stimuli, and that this effect would be greater for social pictures compared with non-social pictures. We then used the AUC scores in LMEMs (one each for VAS playful, VAS loving, VAS elated, VAS stimulated and MAP) with dose as an independent (fixed) factor, and participant as a random effect.

Although this is the first study explicitly comparing the effects of MDMA on social and non-social stimuli, studies in laboratory animals suggest that MDMA may enhance the value of rewards regardless of their social nature.

The drug also appears to enhance the incentive value of social experiences. In both studies, drug doses were counterbalanced relative to session order, and drug sequences were assigned randomly to participants.

When no measures were scheduled, participants relaxed, watched a movie from a selection available or read. 1 Picture sets for Study 1 were the same as in Wardle and de Wit (2012) , and can be found in the footnote on p. 143 of that article.

In a previous study, MDMA reduced neural responses to threatening faces in healthy volunteers ( Bedi et al. Future studies employing precursor depletion or antagonist methods may help determine the exact neuropharmacological basis of these effects, as would studies directly comparing the effects of MDMA with those of other related drugs in the same participants.
