Although humans measure time using a continuous scale, certain numerical ages inspire greater self-reflection than others. Six studies show that adults undertake a search for existential meaning when they approach a new decade in age (e.g., at ages 29, 39, 49, etc.) or imagine entering a new epoch, which leads them to behave in ways that suggest an ongoing or failed search for meaning (e.g., by...

The purpose of this study was to evaluate the role of diminished arterial blood flow in painful disc

Everyday activities break down into parts and subparts, and appreciating this hierarchical structure is an important component of understanding. In two experiments we found age differences in the ability to perceive hierarchical structure in continuous activity. In both experiments, younger and older adults segmented movies of everyday activities into large and small meaningful events. Older ad...

Objective. To evaluate the difference between chronological and dental age, calculated by Willems and Cameriere methods, in various skeletal patterns according to Steiner's ANB Classification. Methods. This retrospective cross-sectional study comprised the sample of 776 participants aged between 7 and 15 years (368 males and 408 females). For each participant, panoramic images (OPT) and laterol...

Strong relationships have been hypothesized between the timing of marriage and the familial environment of the couple. Sociologists have identified various mechanisms via which the age at marriage in the parental generation might be related to the age at marriage of the children. In our paper we study this relationship for historical populations. We use a dataset consisting of several hundreds ...

We used an alternate age variable, functional biological age (fBioAge), which was based on performance on functional body measures. The aim was to examine development of fBioAge across the adult life span, and to also examine potential gender differences and genetic and environmental influences on change with age. We used longitudinal data (n = 740; chronological age (ChronAge) range 45-85 at b...

PURPOSE This article focuses on using currently available data to assist speech-language pathologists (SLPs) in making decisions regarding a child's eligibility and considerations for recommended "dosage" of early intervention (EI) services. METHOD Literature describing the characteristics of infants and toddlers who are likely recipients of EI services was reviewed. RESULTS Current literat...

This paper explores whether home buyers are myopic about future energy costs. I exploit variation in energy costs in the form of fuel price changes in Massachusetts where there is significant overlap in the geographic and age distributions of oil-heated homes and gas-heated homes. I find that relative fuel price shifts cause relative changes in housing transaction prices that are consistent wit...

The purpose of this study was to examine the effect of practice on simple reaction time (RT), movement time (MT), and response consistency for two arm-reaching tasks of graded complexity in younger and older adults. Forty subjects, 20 younger adults (age range = 20-29 years) and 20 older adults (age range = 60-82 years), were randomly subdivided into practice and control groups. All subjects we...

The current study examined age differences in the association between daily negative affect, average negative affect, and diurnal cortisol among participants from the National Study of Daily Experiences (N = 1,423; age range: 33-84 years). Across four consecutive days, participants reported the negative emotions they experienced and provided four saliva samples per day, from which cortisol was ...
