People think about breaking up more when they look outside their relationship for psychological fulfillment

Are your psychological needs being met?

As humans we all have psychological needs that we are driven to fulfill, be they companionship or safety, a sense of belonging or personal growth. And we often meet these needs through our relationships with others: They care for us, make us feel secure, and help us develop as individuals.


When we are in romantic relationships, our partners are commonly the main source for fulfilling those needs. But sometimes they are away, or are simply not equipped to meet our particular needs. In those cases we turn elsewhere, to friends, family, and others in our lives. This may benefit us personally — but how does it affect our relationship?

To find out, Laura Machia and Morgan Proulx at Syracuse University conducted a series of studies, published in Personality and Social Psychology Bulletin, looking at need fulfillment among American adults in relationships. The first study drew on data collected in the mid-1990s from almost 4,700 participants of the Midlife in the United States longitudinal study. Participants reported how many hours per month their partner, and others outside of their relationship, fulfilled one particular need: emotional support. They also completed a number of scales measuring the quality of their relationship and how often they'd thought that their relationship could be in trouble.

The researchers found that the more emotional support people received from outside their relationship, the more negatively they rated their relationship and the less stable they felt it was. And it wasn't simply that these participants were making up for a lack of fulfillment from within the relationship, the findings held even when the researchers took into account the extent of support provided by participants' partners.

Instead, the team wondered whether having one's needs met outside of a relationship made people more aware that there were other viable options to turn to than just a partner. In a subsequent study, they gave 413 university students questionnaires measuring the "perceived quality of alternatives," rating their agreement with statements like "My needs for intimacy, companionship, etc., could easily be fulfilled in an alternative relationship." Participants also completed scales measuring how often their partner, and other people, met their needs (for instance, self-improvement or companionship), as well as how often they thought about ending their relationship.

The team found that the more participants' needs were fulfilled within a relationship, the worse they perceived the option of going to other people to meet their needs. But the more they actually received fulfillment from those outside sources, the better they rated them — and the more they thought about ending their relationship.

It's an intuitive finding: When people go outside of their relationship to try and meet their needs, they learn there are other options out there and they don't have to rely just on their partner. That doesn't necessarily mean they are finding other romantic partners, the authors add. Rather, receiving fulfillment from outside their romantic relationship "allows an individual to feel that being single, spending time with friends, or finding a new romantic partner at some point is a more viable option for them, in that their need fulfillment would not suffer considerably, should they opt to take one of those paths."

For the most part, the study didn't distinguish between different kinds of psychological need, so it remains to be seen whether there are particular needs to which the results apply most strongly — perhaps those that are closely linked to romantic relationships, for instance, like security and intimacy. There may also be individual differences in how susceptible people are to the effects, something the authors say they will look at in future work.

Is the universe a graveyard? This theory suggests humanity may be alone.

Ever since we've had the technology, we've looked to the stars in search of alien life. It's assumed that we're looking because we want to find other life in the universe, but what if we're looking to make sure there isn't any?

According to the Great Filter theory, Earth might be one of the only planets with intelligent life. And that's a good thing (NASA, ESA, and the Hubble Heritage Team [STScI/AURA]).
Surprising Science

Here's an equation, and a rather distressing one at that: N = R* × fP × ne × f1 × fi × fc × L. It's the Drake equation, and it describes the number of alien civilizations in our galaxy with whom we might be able to communicate. Its terms correspond to values such as the fraction of stars with planets, the fraction of planets on which life could emerge, the fraction of planets that can support intelligent life, and so on. Using conservative estimates, the minimum result of this equation is 20. There ought to be 20 intelligent alien civilizations in the Milky Way that we can contact and who can contact us. But there aren't any.

  • A new study shows e-commerce sites like Amazon leave larger greenhouse gas footprints than retail stores.
  • Ordering online from retail stores has an even smaller footprint than going to the store yourself.
  • Greening efforts by major e-commerce sites won't curb wasteful consumer habits. Consolidating online orders can make a difference.

  • We spend 40 percent of our childhoods asleep, a time for cognitive growth and development.
  • A recent study found an association between irregular sleep patterns in childhood and either psychotic experiences or borderline personality disorder during teenage years.
  • The researchers hope their findings can help identify at-risk youth to improve early intervention.
