Full statistical mediation of the relationship between trauma and depressive symptoms

Owing to the potentially devastating effects of trauma‐induced depression, explaining the relationship between trauma and depressive symptoms is important. In this study, we measured lifelong exposure to potentially traumatic events and depressive symptoms in 370‐female undergraduates. We also measured anxiety, past negative time perspective and dissociation as potential mediators. Trauma exposure and depressive symptoms were related with a small but significant effect size (r = .16). Trauma was not associated with dissociation. We found that past negative time perspective and anxiety were full statistical mediators of this trauma‐depressive symptoms relationship. These two mediators combined accounted for all of the variance in that association. Anxiety accounted for more of the variance than past negative time perspective. A proposed explanation is that trauma both affectively elevates anxiety and cognitively creates an enduring focus on the events. Chronic anxiety and a past negative time perspective may lead to depression over time. The clinical implications are possible explanations as to why some treatments work.     

When less is more: Consumer aversion to unused utility

A series of experiments demonstrates that consumers exhibit aversion to waste during forward-looking purchase. These experiments further reveal that such behavior is driven by distaste for unused utility, a reaction that is shown to be distinct from an aversion to squandering money. Waste aversion is especially pronounced when consumers anticipate future consequences and deprivation is salient. In addition to demonstrating robustness across consumers and marketing contexts, the results also demonstrate how waste aversion can lead to self-defeating behavior in which consumers forego desired utility. Finally, the present research demonstrates and discusses the implications of waste aversion for a variety of marketing issues, including buy-rent markets, bundling, and the fundamental distinction between goods and services.     

The functions of music and their relationship to music preference in India and Germany

Is the use of music in everyday life a culturally universal phenomenon? And do the functions served by music contribute to the development of music preferences regardless of the listener's cultural background? The present study explored similarities and dissimilarities in the functions of music listening and their relationship to music preferences in two countries with different cultural backgrounds: India as an example of a collectivistic society and Germany as an example of an individualistic society. Respondents were asked to what degree their favorite music serves several functions in their life. The functions were summarized in seven main groups: background entertainment, prompt for memories, diversion, emotion regulation, self‐regulation, self‐reflection, and social bonding. Results indicate a strong similarity of the functions of people's favorite music for Indian and German listeners. Among the Indians, all of the seven functions were rated as meaningful; among the Germans, this was the case for all functions except emotion regulation. However, a pronounced dissimilarity was found in the predictive power of the functions of music for the strength of music preference, which was much stronger for Germans than for Indians. In India, the functions of music most predictive for music preference were diversion, self‐reflection, and social bonding. In Germany, the most predictive functions were emotion regulation, diversion, self‐reflection, prompt for memories, and social bonding. It is concluded that potential cultural differences hardly apply to the functional use of music in everyday life, but they do so with respect to the impact of the functions on the development of music preference. The present results are consistent with the assumption that members of a collectivistic society tend to set a higher value on their social and societal integration and their connectedness to each other than do members of individualistic societies.     

Time perspective and environmental engagement: A meta-analysis

Environmental issues entail both a social conflict (private vs. public interests) and a temporal conflict (short- vs. long-term interests). This paper focuses on the role temporal concerns play in influencing environmental engagement by quantitatively integrating results of studies that assessed the associations between time perspective and proenvironmental attitudes and behaviors. The meta-analysis included a total of 19 independent samples and 6,301 participants from seven countries (Australia, Brazil, Germany, Mexico, New Zealand, Norway, and the United States). Results showed that the associations between time perspective and proenvironmental behaviors were higher than those for proenvironmental attitudes. Supporting predictions, the associations between future time perspective and proenvironmental behaviors were strong and nontrivial compared to those for the combined past-present time perspective. The findings indicate that future time perspective seems to play an important role in influencing individuals' attitudes and behaviors towards the environment. Implications of the findings for theory and practice are discussed.     

Individual differences in vulnerability to subjective time distortion1

Time duration is perceived to be longer when accompanied by dynamic sensory stimulation than when accompanied by static stimulation. This distortion of time perception is thought to be due to the acceleration of an internal pacemaker that has been assumed to be the main component of temporal judgments. In order to investigate whether the function of the internal pacemaker is modality dependent or independent, we examined the correlation of visual flicker and auditory flutter effects on a temporal production task. While seeing a 10‐Hz visual flicker or hearing a 10‐Hz auditory flutter, participants estimated a duration of 2500 ms as accurately as possible by pressing a button. The results showed a significant within‐individual correlation between the time distortion due to visual flicker and that due to auditory flutter. Additionally, we found that time distortion due to auditory flutter tended to be larger in female participants than in male participants. These results suggest that the mechanisms underlying subjective time dilation are similar between vision and audition within individuals, but that they vary across individuals.     

Thinking Outside the Clocks: The Effect of Layered‐Task Time on the Creative Climate of Meetings

The turbulence of the new economy puts demands on organizations to respond rapidly, flexibly and creatively to changing environments. Meetings are one of the organizational sites in which organizational actors “do” creativity; interaction in groups can be an important site for generating creative ideas and brainstorming. Additionally, Blount (2004) demonstrated the importance of organizational temporalities for group performance. We draw on both of these literatures and examine how temporal structures influence the climate for creativity, or the extent to which creativity is fostered, within groups. Specifically, we develop a hypothesis linking organization‐ and job‐level temporal structures to the extent to which managers structure meetings with a climate supportive of creativity. Our results demonstrate that a nuanced relationship exists between temporal structures and creative climate such that certain temporal structures appear to either enhance or decrease the creative climate of meetings. We end with a discussion of the implications of the findings for management.     

EARLY RESPONSE DISTRIBUTION AND OUTCOMES OF RESPONSE-RESTRICTION ANALYSES

We examined whether the results of a response‐restriction analysis (RRA) could be predicted on the basis of response distribution in early sessions, when these sessions indicated interaction with multiple items. Four preschool‐aged children participated. For 3 of the 4 participants, the results from sessions conducted prior to restriction of the first item corresponded closely with results of the full RRA.     

THE EFFECTS OF FIXED-TIME REINFORCEMENT SCHEDULES ON FUNCTIONAL RESPONSE CLASSES: A TRANSLATIONAL STUDY

Research on functional response classes has applied significance because less severe forms of problem behavior have been found to co‐occur with more severe forms. In addition, the most severe forms of problem behavior are sometimes targeted for intervention without monitoring other less severe forms. In such cases, it is unknown whether and how untreated forms of problem behavior covary with the targeted behaviors. The present study employed a translational procedure (with button presses as the target behavior) to investigate response covariation under noncontingent reinforcement with typically developing preschoolers. The results indicated that noncontingent reinforcement was generally effective in decreasing all response class members when only one member was targeted.
