About this study
Official title: The Effects of Oxytocin on Learning With Social Versus Nonsocial Motivation
One well-established cognitive theory propose a divide between social and non-social (i.e., cognitive) systems. However, recent work suggests that traditionally social systems can be utilized to enhance cognitive performance. In this study the investigators aim to explore this cooperation between oft-competing systems by instructing participants to learn information because they will be subsequently tested (the nonsocial learning-for-testing condition), or because they will be teaching the information to someone else (the prosocial learning-for-teaching condition). This latter condition relies upon the mentalizing system, which is used to contemplate another person's mental state, rather than traditional memory systems. This implies that the mnemonic powers of the mentalizing system can be leveraged in the learning of a broad array of non-social topics. Furthermore, there is also an emerging literature on the role of oxytocin, a neuropeptide naturally produced in the hypothalamus, in memory that parallels the social/nonsocial split. Oxytocin may benefit the learning-for-teaching group both in terms of enhancing initial social motivation and efficient use of the mentalizing system and then also in terms of memory consolidation for this information learning under socially-motivated conditions.
The investigators expect to replicate the basic learning-for-teaching effect such that those in the teaching condition will remember more than those in the testing conditions. They also expect an interaction between oxytocin administration and learning condition such that oxytocin administration should enhance learning for socially-motivated learning exclusively.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Intranasal oxytocinDrug
Also called Syntocinon nasal spray
Through the use of 1oz bottles attached with metered nasal pumps (1 puff = .1ml), participants will self-administer 24 IU oxytocin (Syntocinon, Novartis Pharmaceuticals). 5 puffs per nostril (1 puff = 2.4 IU oxytocin).
Intranasal placeboDrug
Through the use of 1oz bottles attached with metered nasal pumps (1 puff = .1ml), participants will self-administer 5 puffs per nostril. Placebo consists of: 2 mls Glycerine and 3 mls purified water (methylparaben and propylparaben mixed according to purified water formula) for a total of 5 ml, which will be filtered with a 5mu filter.
| Study group | Role | What they receive |
|---|---|---|
| Intranasal oxytocin | Experimental | Participants will self-administer 24 IU oxytocin (Syntocinon, Novartis Pharmaceuticals). 5 puffs per nostril (1 puff = 2.4 IU oxytocin). Receives: Drug: Intranasal oxytocin |
| Intranasal placebo | Placebo comparator | 2 mls Glycerine and 3 mls purified water (methylparaben and propylparaben mixed according to purified water formula) for a total of 5 ml, which will be filtered with a 5mu filter. Participants will self-administer 5 puffs per nostril. Receives: Drug: Intranasal placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Changes in brain neural activity, observed by fMRI, in response to a reading comprehension task
Whole brain and region of interest (ROI) regression analysis will be used to compare the neural activity of participants in the tutor/memorizer and oxytocin/placebo groups. A design matrix will be created for each participant, modeling activity that is greater during reading comprehension compared with the grammar control passage. First level analyses will compare the response during the reading comprehension passages relative to the grammar control passages. Second level group analyses will compare the first level contrasts between the tutor vs. memorizer groups as well as the oxytocin vs. placebo groups. In regression analyses we will enter each participant's comprehension test score in the tutor and then memorizer condition as a regressor in a whole-brain and ROI analysis to determine which brain regions were more active during the encoding of the reading comprehension passage compared to the grammar control passage.
Measured: Between 40-90 minutes post administration
Secondary outcomes (1)
Performance on a memory test of reading comprehension as measured by percentage of questions answered correctly
Accuracy will be calculated for each participant by dividing the number of correct responses by the total number of questions. We will then conduct a between-subjects 2x2 ANOVA on the accuracy scores for the four groups of interest (i.e., oxytocin-tutor, oxytocin-memorizer, placebo-tutor, placebo-memorizer). A significance level of p<.05 will be used to determine whether there are significant differences between the groups. We will examine whether there is a main effect of either factor (oxytocin vs. placebo, tutor vs. memorize) as well as an interaction between the factors of interest.
Measured: Between 40-90 minutes post administration

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Intranasal oxytocin in people with Social Psychology, run by University of California, Los Angeles at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 31 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 10 Aug 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Changes in brain neural activity, observed by fMRI, in response to a reading comprehension task (time frame: Between 40-90 minutes post administration). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02393443, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Aug 2017.
