Would you be happier if you were richer? A focusing illusion.

The belief that high income is associated with good mood is widespread but mostly illusory. People with above-average income are relatively satisfied with their lives but are barely happier than others in moment-to-moment experience, tend to be more tense, and do not spend more time in particularly enjoyable activities. Moreover, the effect of income on life satisfaction seems to be transient. We argue that people exaggerate the contribution of income to happiness because they focus, in part, on conventional achievements when evaluating their life or the lives of others.

Why are you calling me? How study introductions change response patterns.

PURPOSE: Research on survey methodology has demonstrated that seemingly innocuous aspects of a survey's design, such as the order of questions, can produce biased results. The current investigation extends this work by testing whether standard survey introductions alter the observed associations between variables. METHODS: In two experimental studies, we invited Parkinson's disease (PD) patients to participate in a telephone survey of (a) Parkinson's patients, conducted by a regional medical center, or (b) the general population, conducted by a regional university. The survey in Study 1 (n = 156) first assessed life-satisfaction, and subsequently health satisfaction. In Study 2 (n = 99), we reversed the order of the two questions, asking the health questions first. RESULTS: When the introduction focused on Parkinson's disease, we observed an increased correlation between life-satisfaction and a later question about health satisfaction (r = 0.34 vs. 0.63 after general population versus Parkinson's introduction, respectively; Study 1). In Study 2, asking the health questions first resulted in high correlations regardless of the introduction; in addition, judgments of life-satisfaction were lower after the Parkinson's-focused introduction. CONCLUSIONS: When participants were informed prior to the survey that its purpose was to examine well-being in PD, health satisfaction was a much more important component of life-satisfaction, accounting for three times as much variation. We hypothesize that the survey introduction primed participants' health status, resulting in an artificially large correlation with life-satisfaction.

A population approach to the study of emotion: diurnal rhythms of a working day examined with the Day Reconstruction Method.

To date, diurnal rhythms of emotions have been studied with real-time data collection methods mostly in relatively small samples. The Day Reconstruction Method (DRM), a new survey instrument that reconstructs the emotions of a day, is examined as a method for enabling large-scale investigations of rhythms. Diurnal cycles were observed for 12 emotion adjectives in 909 women over a working day. Bimodal patterns with peaks at noon and evenings were detected for positive emotions; peaks in negative emotions were found at mid-morning and mid-afternoon. A V-shaped pattern was found for tired and an inverted U-shaped pattern for competent. Several diurnal patterns from prior studies were replicated. The DRM appears to be a useful tool for the study of emotions.

Clinical and parasitological characteristics of puerperal malaria.

BACKGROUND: Women with semi-immunity to malaria who live in regions where the disease is endemic are at increased risk for more frequent and severe episodes of malaria during pregnancy. Recent findings indicate that this increased risk might persist beyond delivery, but the underlying mechanisms for this change in risk are poorly understood. METHODS: One hundred fifty women were included in a cohort study in Lambaréné, Gabon, and were actively followed up weekly for 10 weeks after delivery, as were nonpregnant control women who had been matched to them by location and age. Parasites in samples of placenta and blood were genotyped by use of polymerase chain reaction amplification of the merozoite surface antigen 2 gene and the subtelomeric variable open reading frame gene of Plasmodium falciparum. RESULTS: Eleven puerperal women had cases of clinical malaria, compared with 1 control woman (rate ratio, 9.8; P=.006). Eighteen puerperal women had P. falciparum parasitemia, compared with 6 control women (rate ratio, 2.7; P=.03). Five of 16 puerperal women (31%) with parasitemia on follow-up had identical parasites in their placentas and blood, and 11 of these cases (69%) were the result of reinfection. Puerperal women remained at equal risk for the development of parasitemia throughout the first 10 weeks after delivery. Use of bed nets, use of chloroquine prophylaxis during pregnancy, presence of malaria episodes during pregnancy, gravidity, and age were not associated with the acquisition of parasitemia during follow-up. CONCLUSIONS: Compared with nonpregnant women, puerperal women have a considerably increased risk for the development of malaria and/or parasitemia. This increased risk is caused both by the recurrence of P. falciparum parasitemia and by the increased susceptibility to new infections, although the latter plays a more significant role.

Misimagining the unimaginable: the disability paradox and health care decision making.

Good decision making often requires accurate predictions about how potential outcomes will make one feel. However, people often mispredict the emotional impact of unfamiliar circumstances. For example, they often overestimate the emotional impact that chronic illnesses and disability will have on their lives. In the present article, the authors look at possible sources of error in both the happiness reports of patients with chronic illness or disability and the happiness predictions of healthy people asked to imagine the same illnesses and disabilities. On balance, the available evidence suggests that, whereas patients misreport their well-being, healthy people also mispredict the emotional impact that chronic illness and disability will have on their lives.

A survey method for characterizing daily life experience: the day reconstruction method.

The Day Reconstruction Method (DRM) assesses how people spend their time and how they experience the various activities and settings of their lives, combining features of time-budget measurement and experience sampling. Participants systematically reconstruct their activities and experiences of the preceding day with procedures designed to reduce recall biases. The DRM's utility is shown by documenting close correspondences between the DRM reports of 909 employed women and established results from experience sampling. An analysis of the hedonic treadmill shows the DRM's potential for well-being research.

Integrating temporal biases: the interplay of focal thoughts and accessibility experiences.

We provide an integrative account of temporal biases (confidence changes, planning fallacy, impact bias, and hindsight bias). Students listed either 3 or 12 thoughts about success or failure before an upcoming real-life exam or immediately after learning their grades. Previous explanations had focused on how thought content alone (what comes to mind) influences temporal biases. We found, however, an interaction between thought content and accessibility experiences (how easily or difficultly thoughts come to mind). Thinking about 3 ways to succeed (success was easy to bring to mind) was equivalent to thinking about 12 ways to fail (failure was difficult to bring to mind), and conversely, thinking about 3 ways to fail was equivalent to thinking about 12 ways to succeed. In no case was thought content alone sufficient to predict the biases. These results have implications for debiasing strategies and other judgments over time.

Processing fluency and aesthetic pleasure: is beauty in the perceiver's processing experience?

We propose that aesthetic pleasure is a function of the perceiver's processing dynamics: The more fluently perceivers can process an object, the more positive their aesthetic response. We review variables known to influence aesthetic judgments, such as figural goodness, figure-ground contrast, stimulus repetition, symmetry, and prototypicality, and trace their effects to changes in processing fluency. Other variables that influence processing fluency, like visual or semantic priming, similarly increase judgments of aesthetic pleasure. Our proposal provides an integrative framework for the study of aesthetic pleasure and sheds light on the interplay between early preferences versus cultural influences on taste, preferences for both prototypical and abstracted forms, and the relation between beauty and truth. In contrast to theories that trace aesthetic pleasure to objective stimulus features per se, we propose that beauty is grounded in the processing experiences of the perceiver, which are in part a function of stimulus properties.

Zeroing in on the dark side of the American Dream: a closer look at the negative consequences of the goal for financial success.

Recent research has demonstrated that aspiring to the American Dream of financial success has negative consequences for various aspects of psychological well-being. The present longitudinal study examining the relation between the goal for financial success, attainment of that goal, and satisfaction with various life domains found that the negative impact of the goal for financial success on overall life satisfaction diminished as household income increased. The negative consequences of the goal for financial success seemed to be limited to those specific life domains that either concerned relationships with other people or involved income-producing activities, such as one's job; satisfactions with two of those life domains, however, were among the strongest predictors of overall life satisfaction in this sample of well-educated respondents in their late 30s. The negative consequences were particularly severe for the domain of family life; the stronger the goal for financial success, the lower the satisfaction with family life, regardless of household income.

The activation of aging stereotypes in younger and older adults.

The activation of ageism and aging stereotypes in younger and older adults was investigated by manipulating both the valence and the stereotypicality of trait stimuli. Participants completed a lexical decision task in which the stimulus onset asynchronies (SOAs) between the prime and target stimuli were varied to examine the effects of automatic and controlled processing (300 and 2,000 ms, respectively). Both younger and older adults demonstrated strong stereotype activation for elderly stereotypes but relatively weak activation for young stereotypes. Both younger and older adults also demonstrated a positive bias toward older people, which was not moderated by SOA. These findings suggest that younger and older adults do not differ in their accessibility to aging stereotypes or to their age-based biases, which appear to be positive toward elderly people.

Accessibility experiences and the hindsight bias: I knew it all along versus it could never have happened.

In two experiments, we tested accessibility experiences versus accessible content in influencing the hindsight bias when participants generated either thoughts about alternative outcomes or thoughts about known outcomes. Participants who had listed many thoughts (Experiment 1) and those who had contracted their brow muscles (Experiment 2) when considering alternate outcomes rated the known outcome as more likely than did than those who had listed two thoughts or who had not contracted their brows--a "backfire" effect. In contrast, but no less ironically, participants who had listed many thoughts and those who contracted their brows when considering known outcomes rated those outcomes as less likely--an "it could never have happened" effect. Both effects are due to subjective accessibility experiences, and their role in influencing and debiasing the hindsight bias is discussed.

When debiasing backfires: accessible content and accessibility experiences in debiasing hindsight.

Two studies demonstrated that attempts to debias hindsight by thinking about alternative outcomes may backfire and traced this to the influence of subjective accessibility experiences. Participants listed either few (2) or many (10) thoughts about how an event might have turned out otherwise. Listing many counterfactual thoughts was experienced as difficult and consistently increased the hindsight bias, presumably because the experienced difficulty suggested that there were not many ways in which the event might have turned out otherwise. No significant hindsight effects were obtained when participants listed only a few counterfactual thoughts, a task subjectively experienced as easy. The interplay of accessible content and subjective accessibility experiences in the hindsight bias is discussed.
