Correspondence between children's and adults' ratings of stimulant-induced changes in ADHD behaviours in a crossover trial with medication-naive children

Correspondence between children's and adults' ratings of changes in ADHD behaviours was investigated in a paediatric ADHD stimulant crossover trial. Thirty-one children completed an ADHD self-report scale each week, and comparisons were made with an ADHD questionnaire completed by adults (combined parent and teacher ratings). Children's and adults' ratings demonstrated good internal consistency, were significantly associated with the assessment of ADHD behaviours in the placebo condition and showed comparable responsiveness to stimulants at the group level. Furthermore, a large and significant correlation was detected between the two sets of informants' ratings of changes from placebo to both methylphenidate and dextroamphetamine high-dosage conditions, but not from placebo to low-dosage conditions. Agreement in the categorization of best stimulant condition for individual children was significant, but modest from a clinical perspective. The results indicate that children's ratings correspond adequately with adults' ratings, and thus appear to be a complementary outcome measure.     

Understanding money's limits: People's beliefs about the income – Happiness correlation

It is claimed that the correlation between income and happiness is considerably weaker than people expect and recent research supports that contention. However, an important lesson from judgment and decision-making research is that judgments are constructed in response to the prevailing context, leaving open the possibility that some elicitation procedures may reveal accurate intuitions about income and happiness. We examined whether this is so. Study 1 participants ranked a set of empirical relationships according to the strength of correlation and we examined whether they ranked the income–happiness link where it actually falls in the set. In Studies 2 and 3, participants estimated the probability that someone with a higher income than another is also the happier of the two. The estimates of the participants were then compared to the actual probability based on the documented income–happiness relationship. Results indicate that, using these elicitation procedures, people have an accurate understanding of the relationship between income and happiness.     

Autobiographical narratives of spiritual experiences: Solitude,tragedy, and the absence of materialism

Two studies examined the interaction between subjective well-being (SWB) and meaning in life (MIL) vis-à-vis self-perceptions of actual or potential threats to one's physical and mental integrity, hereby defined as the hostile-world scenario (HWS). Study 1 (N?=?608) showed that the relationship between SWB and MIL strengthened as the HWS increased. Study 2 (Survey of Health, Ageing, and Retirement in Europe; SHARE-Israel; N?=?1665) similarly showed that SWB and MIL were strongly linked as lifetime cumulative adversity, the ultimate realization of the HWS, increased. Study 2 further showed that when one construct (whether SWB or MIL) was low, the other construct acted as a moderator of the effect of cumulative adversity on functioning. In conclusion, although SWB and MIL are more strongly linked under adverse circumstances, they are likely to compensate for each other, perhaps due to their unique operations.     

Subjective temporal trajectories for subjective well-being

Based on Diener's (Diener, E. (1984). Subjective well-being. Psychological Bulletin, 95, 542–575.) tripartite model of subjective well-being (SWB), subjective evaluations of past, present, and anticipated future life satisfaction (LS), positive affect (PA), and negative affect (NA) were evaluated in a cross-sectional undergraduate sample. Upward mean trends in subjective trajectories (past?<?present?<?future) were typical, on average, for each SWB component. As predicted, higher levels of present SWB were aligned with greater positive psychological, physical, and interpersonal functioning. In contrast, steeper upward subjective SWB trajectories were associated with greater distress and dysfunction. Of the three SWB components, unique links with indicators of functioning were most consistent for LS trajectories. We conclude that a temporally expanded conceptualization of SWB spanning subjective assessments of past, present, and anticipated future LS, PA, and NA provides a rich framework for studying the structure of SWB and the significance of how people perceive their well-being to be unfolding over time.     

Character strengths and well-being among volunteers and employees: Toward an integrative model

The endorsement and deployment of character strengths in occupational contexts are two promising components for understanding how people create well-being. In this study, a model integrating character strengths, satisfaction with occupational activities, and meaning and well-being was proposed and tested in two samples of volunteers and a sample of working adults. The model fit the data well in all three samples. Results demonstrated that deploying strengths at work provided key links to satisfaction with voluntary and paid occupational activities and to meaning among both young and middle-aged volunteers, and adult working women. Among adult volunteers and paid workers, endorsing strengths was related to meaning, while both endorsing and deploying strengths were related to well-being. Together, these studies provide a model for understanding how strengths may play a role in how both volunteer and paid workers find meaning, well-being, and satisfaction.     

Influences on current mood of eliciting life-satisfaction judgments

Subjective well-being (SWB) has attracted a plethora of cross-disciplinary research in recent years. As measured in this research, SWB includes a cognitive and an affective component. We hypothesize that eliciting the cognitive component by means of life-satisfaction judgments activates thoughts about positive and negative life circumstances that influence the affective component (current mood or memory of the frequency of past positive and negative affects). Experiment 1 demonstrates an expected asymmetrical carryover effect in that current mood correlates higher with life-satisfaction judgments performed before than after the measurements of current mood. In Experiment 2, it is found that inducing current mood by means of rewarding performance does not influence the life-satisfaction judgments. In contrast and consistent with Experiment 1, Experiment 3 shows such an influence when current mood is induced by thinking about positive and negative life circumstances.     

Life satisfaction across adulthood: different determinants at different ages?

It is likely that with aging and changing life circumstances, individuals’ values shift in systematic ways, and that these shifts may be accompanied by shifts in the determinants of their subjective judgments of well being. To examine this possibility, the relations among the Satisfaction With Life Scale (SWLS) and a number of personality, affect, demographic, and cognitive variables were examined in a sample of 818 participants between the ages of 18 and 94. The results indicated that although many variables had significant zero-order correlations with the SWLS, only a few variables had unique utility in predicting life satisfaction. Invariance analyses indicated that while the qualitative nature of life satisfaction remains constant across adult age, the influence of fluid intelligence on judgments of life satisfaction declines with age. In contrast, negative affect is negatively associated with life satisfaction consistently across the adult age span.     

Programming of time-to-peak force for brief isometric force pulses: Effects on reaction time

According to the parallel force unit model (PFUM) the programming of an isometric force pulse requires the specification of the number of force units and force unit duration. The programming of a force pulse with minimal time-to-peak force is an exception, however, as force unit duration is limited by the minimal possible value, which should be easier to adjust than larger force unit durations. Therefore, the duration of the programming process should be shorter for these force pulses and hence should result in shorter reaction time (RT). Four experiments assessed this prediction using a response precueing procedure. In each experiment the participants produced isometric flexions with their left or right index finger, and time-to-peak force was manipulated within a block. The results are consistent with the predictions of PFUM. The results, however, are at variance with alternative accounts which assume that RT depends primarily on response duration or rate of force production.     

Is advance reconfiguration in voluntary task switching affected by the design employed?

In task switching, when the amount of preparation time is increased, a reduction in switch cost or RISC effect is observed. This RISC effect is frequently attributed to advance reconfiguration processes. In the explicit task-cueing procedure, RISC effects are observed when varying the preparation time within participants but not when varying the preparation time across participants—a finding suggesting that RISC effects in the explicit task-cueing procedure are restricted to specific designs. The present study investigated RISC effects in voluntary task switching and compared RISC effects in a within-subjects design with RISC effects in a between-subjects design. Our results indicate that RISC effects are present in both designs. We conclude that advance reconfiguration in voluntary task switching is robust.
