New Authors – Welcome!

If you have been at the Radboud University in Nijmegen lately – you might have seen this ad (PDF). The Behavioural Science Blog is looking for new authors. Lots of them!

Writing this blog (together with Christina now for some times) has been one of the most interesting and also rewarding steps I have taken in my academical carrier.

Behavioural Science is often characterized by ground breaking, but very low-level research. Oftentimes it is only a very select group that actually read the article and  often projects get abandoned, because the end goal “scientific article” is so far away.

I also wonder sometimes why we, as scientists, still use this very complicated system of scientific journals. Okay let’s be honest. Peer reviewed journals are very important when it comes to select high quality research – that’s for sure. But what is with all those really good, but not perferct research? And what is about those great ideas that you have, but never act upon?

As we enter the digital age this will all change – communication will be open, instead of closed. Ideas will spread fast, instead of slow and (from my perspective the best improvement) “ordinary” people will have access to scientific data and ideas.

However the language suited for writing for a select group of knowledgable people is different from the style when writing for “normal” people. It’s all about “What does that tell us?”, “WOW” and “Oh yes…I can use this piece of information for doing X!”.

This is what the Behavioural Science Blog is all about – and I think Dan said it best (so I put it in the ad):

Join us in our quest for high-quality and comprehensive articles written for those who want to follow the latest research, but find traditional sources inaccessible.

Change won’t come on its own.

Join it now and get your message out there!

If you want to become a part of this blog just send me an email and tell me a little bit about who you are and what you would like to write about. Videos, pictures, articles – it’s all welcome. The only thing I ask from you is that it comes in a format that makes it comprehensive to a large group of people, not only scientists in the field of behavioural science.

This has been a great journey for me and I enjoyed every bit of it. I hope you will enjoy it, too!

Behavioral Assessment of Social Anxiety in the Free Speech Task

with one comment

The current study aimed to improve understanding of the behavioral indicators of social anxiety in the Free Speech Task. Building on the current theoretical knowledge about social anxiety, we developed a rating system to maximize the sensitivity of the behavioral anxiety assessment in the Free Speech Task. Participants with social anxiety and a control group were asked to give a free speech about their study for two minutes. A general measurement of anxiety and different specific behavioral indicators of anxiety were assessed. The scores were rated on interrater reliability and the behavioral strategies for socially anxious and nonanxious participants were compared. The rating of general anxiety did not differ between the anxious and the nonanxious group, only one specific measurement (fumbling/selfmanipulation) did differ significantly between these two groups. These results indicate that socially anxious and nonanxious individuals differ in their internal physical behavior. This finding might have implications for the behavioral assessment of social anxiety.

Can People who lack Self-Regulation Skills still have Satisfying and Well-functioning Relationships?

with 4 comments

A healthy and stable relationship requires both partners to interact on a frequent and regular basis. Different interests need to be discussed, activities need to be planned and coordinated, different tasks need to be done in a joint effort – and if children come into the equation things do not get more relaxed. Recent literature suggests that interactions that require high levels of social coordination impair cognitive functioning (Finkel et al., 2006). And even though we might show more of our “true self” to our partner than to other people, self-presentation also plays a role in intimate relationships. This is important, because there is evidence that self-presentation is a cognitively costly process (Vohs, Baumeister, & Cariocco, 2005). Furthermore one can assume that with time, people in a close relationship get to know the other person better, which means that we are able to understand the wishes and interests of the partner much better. But this also gives us the responsibility to consider those wishes and we might feel forced to reconsider often. In other words we are forced to self-regulate.

The term self-regulation relates to the many (cognitive) processes that manage drives and emotions. Most important, self-regulation keeps us from acting on our first impulses and helps us concentrate. When we interact with each other, we hardly ever say directly what we think – and for a good reason: We are bound by the rules of our culture and sub-culture to interact in a way that respects the feelings and personal space of those we are interacting with. The most important tool for promoting effective interactions is self-regulation.

Since self-regulation is such an important skill in todays society, it is related to many positive outcomes, such as success in school and university, social economic status, health and also relationship satisfaction. Absence of self-regulation is often related to problems in interpersonal interaction, addiction and mental diseases. Recent studies on the quality of self-regulation indicate that it is both, a trait and an ability. People with high self-regulation ability can control their impulses much easier than people with low self-regulation ability. However it is also the case that self-regulation can be trained: Repeated acts of self-regulation enlarge the total pool of energy we have (Muraven & Baumeister, 2000). Current scientific knowledge proclaims that all the energy of a person is drawn from a single source (Baumeister & Heatherton, 1996). One single act of self-regulation can have an effect on our behavior on a very different task, because we lack the energy that is necessary to control our impulses; this state is called ego-depletion. It can be restored by rest and by positive affect.

On the bright side, a healthy relationship has many positive results (especially for men). If we are in a happy relationship, we receive positive affect from the other, we can talk about ourselves and things that touch us emotionally and reflect together on our emotions, fears and plans for the future. A healthy relationship is regarded as one of the best buffers against stress (Kumashiro & Sedikides, 2005). A fulfilling relationship certainly is on the top of the wish list of many people in the (western) world, however this wish often stays a wish, as can be seen in the raising numbers of divorces. It might be that living in a close and healthy relationship is the “normal thing” for most people, the relationship set-point. Thus the lack of a healthy relationship might be the source of stress. This is true for the absence of a relationship and for a relationship that is characterized by destructive interaction patterns.

Any relationship, and intimate relationships especially, involve a wide array of processes, that demand that we regulate ourselves, but also replenish our resources. It is most parsimonious to assume that within any intimate relationship many different processes interaction with each other, forming a dynamical system. Thus predictions about which behavior will lead to what result are very difficult to make. However, research has shown that the ability to exercise self-regulation is important for several aspects of a relationship. For example Finkel and Campbell (2001) found that self-regulation can help to react in a positive and constructive way to negative comments by the partner. This can help to prevent lapsing into a vicious circle of destructive interaction patterns. In another study Finkel and Campbell (2001) found that persons, that had the ability for self-regulation, were much more forgiving about negative behavior of their partners, compared to individuals that had been ego-depleted beforehand. It has also been found that suppressing criticism can be negative, because suppressing thoughts that are potentially threatening to the relationship requires energy. In other words: The daily struggle not to mention the dirty dishes standing around might be quite ego-depleting. This will probably lead us to snap at our partner quite harshly for some little thing. Big fights often start with little things. A healthy relationship allows both partners to articulate their problems and issues in a positive constructive way, before they become a real problem. “Talking it out” might therefore be an effective strategy to preserve our energy resources. Another problem in heterosexual intimate relationships is that interaction with the opposite sex might require more self-regulation than interaction with someone of the same sex (Metzmacher, Nauts & Rommerswinkel, 2008). Possible explanations for this fact are enhanced self-presentation goals or different interaction styles. Men and women are, for example, inclined to talk about different topics (Bischoping, 1993), men interrupt their interaction partners more often than women do (Anderson & Leaper, 1998), and there are differences in nonverbal behavior between the sexes (Bente, Donaghy & Suwelack, 1998).

However, most evidence for the connection between self-regulatory abilities and relationship-satisfaction found so far is correlative. Studies that have experimentally manipulated self-regulation have (for understandable reasons) focussed on a specific aspect of the relationship, such as forgiveness. Since our understanding of the dynamics involved in intimate relationships is still quite rudimentary, I believe that we cannot, at this point, generalize those results to the broad term of relationship satisfaction.

At this point it is wise to come back to the original questions: Can people who lack self-regulation skills have a satisfying and well-functioning relationship? There are definitely some kind of (hypothetical) relationships that would not require self-regulation of both partners and therefore could be called well-functioning, if the other partner is happy with his or her role. In asymmetrical relationships, in which (often) the man is the patriarch and has the power to do what he pleases, he could act upon his impulses without self-regulating, if culture (or something else for that matter) does not restrict him. Another possibility would be a relationship in which both partners are totally free to do whatever they want, some kind of “flower-power free love” relationship. However I believe that after a short time clashes of interest would arise. Thus this kind of relationship might work for a short period of time, but not for an extended period. I conclude that it is possible for people to have a satisfying and well-functioning relationship without self-regulation, but in my view this extends to only one partner. In most cases of “normal” relationships, even those asymmetrical, I believe that self-regulation is a necessary skill to build effective interactions pattern that benefit both partners.
