Research Interests

 

Broadly speaking, my research is on Subjective Well-Being (SWB), which is the scientific term for happiness.  I have been researching and teaching in this area for over 15 years.  Specifically, I am interested in the role of memory in SWB, and the influence of culture on happiness and conceptions of The Good Life.  I have also studied psychological maturity over time and its relation to well-being. 

 

 

Memory and emotion

I am interested in what influences people’s recall of their past emotions.  Understanding memory for emotions is important because our conceptions of our lives, especially meaningful (and therefore usually emotional) experiences, are based primarily on what we recall.  Additionally, most measures of emotion are retrospective measures, so it is important to know whether such measures accurately reflect momentary experiences.  In addition to retrospective measures, I use experience sampling methodology which relies less on recall (Scollon, Kim-Prieto, & Diener, 2003; Tov & Scollon, 2011).  Respondents in my studies record their emotions on palmtop computers at several random moments each day when signaled.  Clear discrepancies have emerged between retrospective reports and momentary or “on-line” reports.  Rather than treating inaccuracies in recall as error, however, my research seeks to uncover systematic mechanisms that guide memory for emotions.  For example, I found that one’s emotional self-concept predicts memory for emotions, even after controlling for on-line experiences (Scollon, Diener, Oishi, & Biswas-Diener, 2004).  In other words, instead of searching their memories and summing up specific instances of emotion to arrive at an estimate of their past emotions, people use heuristic information such as the self-concept to inform their recall.  In addition, this effect has been replicated among different cultural groups.

Memory for emotions also determines the choices people make, as my colleagues at Illinois and I have demonstrated.  We had participants record their on-line affect several times each day during their Spring Break vacations (Wirtz, Krueger, Scollon, & Diener, 2003).  The best predictor of whether students wanted to take a similar vacation in the future was not on-line emotion during the vacation, but rather their memory for emotions.  Moreover, expectations about the vacation influenced memories.  The same is also true for how students make decisions about which courses to take.  The actual experience matters very little, whereas the memory drives decision-making. 

These findings challenge our conceptions of happiness.  Is happiness the sum of pleasant experiences or pleasant memories?  Are people aware of the role of memory for emotions in their overall happiness?  A couple pilot studies I conducted seem to suggest the answer to the latter is No.  Respondents generally prefer happy experiences over happy memories.  It’s possible that implicit theories of happiness emphasize maximizing momentary pleasant affect, but perhaps not happy memories.

 

Culture and emotion

By using multiple measures of emotion, my research provides an intricate picture of the emotional lives of individuals in different cultures.  In doing so, I hope to uncover sources of cultural differences in subjective well-being (SWB), in addition to illuminating the study of individual differences in emotion.  Furthermore, I believe that challenges in cross-cultural measurement can inform the measurement of emotion within cultures.

On-line emotion.  A robust and consistent finding in the well-being literature is that individuals from Asian cultures tend to report lower SWB than individuals from Western and Latin societies.  However, most cross-cultural comparisons of emotion have been based on recalled reports of emotion that are vulnerable to memory reconstruction.  Thus, without on-line measures of emotion, it is unclear whether cultural differences in emotion are due to differences in everyday emotional experience or differences in memory for emotions. 

One of my studies which examined on-line and recalled emotions in European Americans, Latino Americans, Asian Americans, Japanese in Japan, and Indians in India, represents one of the few attempts to empirically establish base-rates of specific on-line emotions in different cultures (Scollon et al., 2004).  In both on-line and retrospective measures, European and Latino Americans scored higher on reports of pleasant emotion and lower on reports of unpleasant emotion than Asian Americans, Japanese, and Indians.  However, on-line methods (especially for negative emotion) showed smaller cultural differences than recall methods, suggesting that cultural norms may have stronger effects on memory than on momentary experience.  Groups also differed more in reports of pleasant emotion than in unpleasant emotion, a finding that supports the notion that pleasant emotions may be more influenced by culture and socialization than unpleasant emotions.  Particularly striking cultural differences emerged on both on-line and recalled measures of pride.  European and Latino Americans reported much more pride than Asian Americans, Japanese, and Indians.  This finding resonates with cultural theories that suggest that pride in individualistic societies is highly valued because it emphasizes the uniqueness of the self.  Importantly, this research demonstrates that culture influences momentary affective experiences as well as memory for emotions.

Structure of emotion. The intersection of culture and emotion also provides an opportunity to examine important structural issues.  One issue that my research addresses is whether the relation between pleasant and unpleasant affect varies by culture and by level of analysis.  I have found that, regardless of culture, pleasant and unpleasant feelings are negatively correlated in momentary experience.  However, at trait levels (i.e., between-persons), pleasant and unpleasant affect are uncorrelated among European and Latino Americans, and positively correlated among Asian Americans, Japanese, and Indians (Scollon, Diener, Oishi, Biswas-Diener, 2005).  In particular, individuals in Asian cultures who experience a great deal of pride also report more guilt, sadness, and irritation, a finding which might explain lower levels of SWB in Asian cultures.  This study highlights the importance of studying emotion at both levels.

Most recently, my student Sharon Koh and I explored cultural differences in the way people store or organize their emotion memories (Koh, Scollon, & Wirtz, in press).  We used a reaction-time paradigm developed by Michael Robinson (see Robinson & Kirkeby, 2004) that allowed us to measure the cognitive representation of emotion memories among our respondents.  We found that Singaporeans represented their emotion memories around social relationships more so than Americans.  However, this cultural difference was fully mediated by emotional consistency.  Singaporeans were less emotionally consistent overall than Americans (meaning, they tended to experience different emotions across different situations), and their inconsistency led to organizing their emotions more around social relationships.  After all, for someone who consistently experiences the same feelings in different situations with different others, there is not much to gain from organizing one’s emotion memories around social relationships.

Indigenous emotions.  Translation adds an extra challenge to the study of emotion across cultures.  For instance, finding the same structure of emotion in different cultures is not sufficient evidence for measurement invariance if the structures are based on English or translated English emotions.  Many cultures have emotions that do not have English equivalents and cannot be directly translated.  By neglecting these culturally “indigenous emotions,” we might inflate the chances of detecting universal structure.  Although indigenous emotions have received treatment in ethnographic studies, my research is the first to use experience sampling to track indigenous emotions (Scollon et al., 2004).  I cluster analyzed emotions in Japan and India and found that indigenous emotions did not form distinct clusters from the pleasant and unpleasant dimensions that are often found in studies using translated English emotions.  This is important because it shows that pleasantness and unpleasantness capture emotional experience in different cultures, and that indigenous emotions are fairly well-represented by Western emotion words.

 

Personality development: Increasing happiness and emotional stability over time

            One obstacle to happiness is high negative affect or neuroticism.  After all, neuroticism is a risk factor in virtually all mental illnesses.  Thus, it follows that one way to become happier might be to reduce one’s level of neuroticism.  Unfortunately, for decades trait theorists promoted the view that traits such as neuroticism were “fixed like plaster.”  Similarly, high stability coefficients of well-being measures were taken as evidence that a person’s happiness was merely a reflection of personality.  According to this bleak view then, both happiness and emotional stability levels are immutable.  Fortunately, we now know that such conclusions were based on a limited approach to change.  Until recently, most studies of change have focused on either stability or mean-levels of traits, both of which mask important processes that may be occurring at the individual level.  Few studies have measured change at the within-person or individual level.  Scollon and Diener (2006) examined data from a longitudinal study (see Headey & Wearing, 1989) that tracked the SWB of over 1,000 Australians over 9 years.  Using growth modeling to estimate intraindividual differences in extraversion, neuroticism, and life satisfaction over time, we found that personality does indeed change at the individual level.  More importantly, we identified systematic ways in which change occurs.  First, growth in marital satisfaction and meaning in life accompanied growth in life satisfaction.  These effects remained even after controlling for general increases in positivity.  Second, decreases in neuroticism and increases in extraversion over time were associated with increased work satisfaction, meaning in life, and fitness and exercise.  Third, although people in general decline in neuroticism over time, having more negative life events attenuated this decline.  Thus, Freud was right after all when he said that the key to happiness was in love and work.  This research has potential to inform interventions aimed at improving well-being.  Moreover, changes that occur at the individual level are, arguably, the changes that matter most to people’s lives.

 

Folk theories of the Good Life

Presumably people seek to maximize those aspects that define the good life; therefore, identifying cultural conceptions of the good life is fundamental to a science of well-being.  My research examines folk theories of what makes life worth living.   Rather than treating folk theories as error-ridden and uninformative, my research views them as a rich source of meaning, representing the intersection of shared beliefs and individual histories. 

In a series of studies conducted with Dr. Laura King, I asked participants to make ratings about the desirability and moral goodness of a life as a function of its happiness, meaning, and wealth (King & Napa, 1998).  People rated happy and meaningful lives as most desirable and morally good, and they rated happy people as more likely to go to heaven.  Whereas researchers previously believed that people value money over happiness, my research shows that people want happiness and meaning more than wealth.  In another set of studies, I included effort or challenge as another feature of the good life (Scollon & King, 2005).  I found that folk theories equated the good life with the easy life when effort was conceptualized as number hours of work.  Effort was rated an important part of a meaningful and happy life only when effort was framed as active engagement that was not energy depleting nor time-consuming.  These folk concepts of effort suggest the possibility that people value hard work in the context of the good life, but only if active engagement does not come at the cost of other life interests.

These studies were the first empirical attempts at mapping folk theories of the good life onto the SWB literature.  More recently, Dr. Derrick Wirtz and I conducted a cross-cultural study of folk concepts of the good life.  Wirtz and Scollon (2012) found that happiness and meaning were the main components of the good life in both Singapore and the US.  Remarkably, the effects were virtually the same in the US over a decade later, and after the great financial crisis of 2008.  Cultural differences also emerged.  Although Singaporeans valued happiness and meaning almost as strongly as the Americans did, wealth also emerged as an important ingredient in their good life.  Given the research showing the toxic effects of materialism on subjective well-being, this valuing of wealth could be seen as a clue to why Singaporeans are less happy than Americans (this was shown in that study and in other data I have).  Following up on this, we conducted an experiment among Singaporean participants in which we manipulated their perspective to be either 3rd person or 1st person.  For the 3rd person manipulation, participants wrote a brief biography of themselves using the 3rd person.  For the 1st person manipulation, participants wrote a brief autobiography of themselves using the 1st person.  We found that the 3rd person perspective led to a greater emphasis on wealth in the good life.  This is consistent with research by Suh (2007) who argued that a focus on the generalized other (i.e., seeing oneself as others see you), causes people to focus on objective or shared notions of what is good (in this case, wealth) as opposed to internal standards of what is good (in this case, happiness).
