Day Persons,Night Persons,and Time of Birth: Preliminary Findings

Abstract

The authors conducted 2 surveys to determine the relationship between time of birth and being a day person or a night person. Day persons are most alert during daylight hours; night persons are most alert during hours of darkness. In Survey 1, the authors asked U.S. high school students to complete the Alertness Questionnaire (B. Wallace, 1993) and to respond to other items related to daytime or nighttime activity. In Survey 2, the authors administered the same items to a U.S. college population. In both surveys, time of birth was significantly related to being a day person or a night person. The results suggest that a critical period for setting the biological clock for alertness may be the moment of birth.     

Exploring the Time Preferences by Procrastinators: Night or Day,Which is the One?

In study 1, trait procrastinators compared to nonprocrastinators claimed they were ‘night persons’, individuals who are most alert and active in the late afternoon and evening hours. However, there were no significant individual differences in time preference for a set of social and individual activities considered pleasurable. In study 2, participants kept daily records for six straight days of when they had engaged in activities. Proneness toward behavioral (but not decisional) procrastination was significantly related to number of activities performed in the evening. Together, these studies suggest that procrastinators may be ‘late starters’ who prefer to engage in daily activities later in the day than early in the morning. © 1997 John Wiley & Sons, Ltd.     

Perceived importance of services for persons with AIDS: recipient, family, caregiver, and public differences

596 adults from a moderately sized community in central California were divided into four groups (person with HIV or AIDS, friend or relative, caregiver or service provider for such a person, or member of the general public) and completed a schedule assessing their perceptions of the importance of 36 items related to potential services for persons with HIV or AIDS. Factor analysis of these items yielded in six constructs (Counseling, Medical, Assistance, Homecare, Adjunct/Auxiliary, and Nontraditional), accounting for 65.0% of the variance. Over-all, regardless of group membership, Medical Services were perceived as of highest importance, but differences were found across all groups regarding Assistance Services and Nontraditional Services for persons with AIDS. Implications and suggestions for research are discussed.     

Sedentary behaviour and sleep problems among young,middle-aged,and older persons in South Africa: A brief report

The study aimed to investigate the relationship between sedentary behaviour and sleep problems in a large national community sample in South Africa. We analysed an existing cross-sectional population data set, the “South African National Health and Nutrition Examination Survey”. The sample included 13 555 individuals (median age 34.0 years, interquartile range 25, range 15–98 years). Overall, the study population engaged < 4 hours (49.5%), 4 – < 8 hours (37.2%), 8 – < 11 hours (9.7%), and 11 or more hours (3.6%) in sedentary time a day. The prevalence of sleeping problems was 6.4% and 6.7% in the less than 4 and less than 8 hours sedentary time categories, respectively. The prevalence of sleeping problems was 9.8% and 9.4% in the less than 11 hours and 11 or more hours sedentary time categories, respectively. In the final adjusted logistic regression model, among 50 years and older, the highest sedentary time category was associated with sleep problems, while there was no association in the younger (15–49 years) age group and in the overall model. This could mean that persons at older age with sedentary behaviour are at an increased risk of sleep problems.     

Declines in non-digital social interaction among Americans, 2003–2017

It is unclear whether Americans spent less time on non-digital social interaction in the 2010s than in the 2000s. In the nationally representative American Time Use Survey administered by the Bureau of Labor Statistics (n = 191,558), U.S. residents 15 years of age and older spent 10 to 11 fewer minutes a day in non-digital social interaction during leisure time in 2017 compared to 2003, which translates to 67 fewer hours a year. The decline was primarily driven by adolescents and young adults ages from15 to 25, who spent between 21 and 23 fewer minutes per day on non-digital social interaction in 2017 compared to 2003, or 140 fewer hours a year. Thus, American adolescents and young adults spent less time on non-digital social interaction in the 2010s, with a less pronounced decline among those ages 26 and over.     

Evaluating the influence of time of day on activity engagement in persons with dementia

Dementia is a serious disease affecting a growing number of people. With the onset of dementia comes a decline in social activity engagement that can negatively impact multiple aspects of a person's life. Research suggests that time of day may influence a person with dementia's behavior, including activity engagement, but such research is limited. The purpose of this study was to evaluate the influence of time of day on engagement in activities in persons diagnosed with dementia. An alternating treatments design was used with three participants to measure activity engagement during two times of day, morning and afternoon, and during two activities, a moderately preferred and a low preferred. Results showed no differentiation in engagement between morning and afternoon activities for all three participants, with high levels of engagement during both times of day. For two participants, results showed no differentiation in engagement between moderately preferred and low preferred activities. For one participant, levels of engagement were higher during moderately preferred activities than during low preferred activities.     

Cross-Sectional Age Analysis of Sleep Problems in 2 to 17 Year Olds with ADHD Combined,ADHD Inattentive,or Autism

Sleep problems are common in autism and ADHD. No study has compared sleep problems by age in 2 to 17 year olds with autism versus ADHD-Combined versus ADHD-Inattentive type. Mothers rated 1415 youth with autism and 1041 with ADHD on 10 Pediatric Behavior Scale sleep items. Nighttime sleep problems were most severe in autism, followed by ADHD-Combined, and then ADHD-Inattentive. Difficulty falling asleep, restless during sleep, and waking during the night were the most common problems. Adolescents slept more at night than other age groups, and youth who slept more at night were sleepier during the day. Sleep problems declined with age, but correlations were small. In adolescence, 63% with autism, 53% with ADHD-Combined, and 57% with ADHD-Inattentive had difficulty falling asleep. Given that the majority of children in all age groups had one or more sleep problem, developmentally appropriate interventions are needed to address sleep difficulties and limit their adverse effects.

     

The role of context expectations and cost of reporting on prospective person memory performance

Prospective person memory refers to the task of being on the lookout for a missing or wanted person. In both laboratory and field‐based tasks, prospective person memory performance has been poor. In the current study, we examined two factors that could be manipulated in the real world to increase successful recovery of missing or wanted persons: expectations of encounter and the cost of reporting wanted persons. Participants completed a computer task that simulated normal day‐to‐day tasks (i.e.., grocery shopping) while looking for four “wanted” persons. Participants who were given accurate context expectations made more accurate sightings and more inaccurate sightings than participants who were given inaccurate context expectations. The cost of reporting a sighting did not affect sighting rates. These findings indicate that people are more likely to notice a wanted person in their environment when they expect to encounter the wanted person in that environment.     

Staying vigorous until work is over: The role of trait vigour,day‐specific work experiences and recovery

Staying vigorous throughout the day is important for work‐related behaviour, subjective well‐being, and for effective functioning in the family domain. This study examined trait vigour (i.e. a person's general level of vigour), day‐specific workload (time pressure, work hours), and recovery resulting from unwinding during leisure time as predictors of day‐specific vigour as experienced at the end of the working day. Seventy‐five individuals from service and public administration organizations completed one general survey and daily surveys two times per day for five working days. Trait vigour, demographic variables and control variables (e.g. job control, home workload) were assessed in the general survey. Day‐specific level of vigour, day‐specific workload, and day‐specific recovery were measured in the daily survey. Analyses following a hierarchical linear modelling approach showed that trait vigour, day‐specific workload and recovery accumulated during the preceding evenings predicted an individual's level of vigour at the end of the working day, after controlling for a range of other variables (gender, age, job control, and home workload). Trait vigour and accumulated recovery experiences interacted significantly to predict vigour at the end of the working day, indicating that individuals high on trait vigour benefit most from recovery experienced over the course of several days.     

Embryos, individuals, and persons: an argument against embryo creation and research

One strategy for arguing that it should be legally permissible to create human embryos, or to use of spare human embryos, for scientific research purposes involves the claim that such embryos cannot be persons because they are not human individuals while twinning may yet take place. Being a human individual is considered to be by most people a necessary condition for being a human person. I argue first that such an argument against the personhood of embryos must be rationally conclusive if their destruction in public places such as laboratories is to be countenanced. I base this argument on a popular understanding of the role that the notion of privacy plays in abortion law. I then argue that such arguments against personhood are not rationally conclusive. The claim that the early embryos is not a human individual is not nearly as obvious as some assert.     

Ambivalence toward mothers who kill: an examination of 45 U.S. cases of maternal neonaticide

Public opinion about neonaticide (the killing of a newborn within the first 24 hours of life) has varied across time and cultures. Some nations have passed legislation on behalf of maternal offenders with the assumption that childbirth, a time of unique biological change, may lead to mental disturbance. The United States, however, makes no such distinction; offenders are prosecuted under general homicide laws. Nevertheless, U.S. courts often consider a mother's emotional and physical condition prior to and during delivery. This study includes 44 female offenders and 45 infant deaths and highlights society's ambivalence toward neonaticide offenders. The authors suggest that this ambivalence may be attributed to: (1) the perception that an offender's emotional and physical turmoil during the birth and homicide reduces her culpability; (2) the sentiment that neonaticide offenders are more "redeemable" than other offenders; and (3) the uncertainty about the personhood of a fetus or newborn.     

Evidence for a positive ecological correlation of regional intelligence and suicide mortality in the United States during the early 20th century

Several contemporary cross-national and intranational geographic studies have reported positive ecological (group-level) associations of intelligence and suicide mortality. These findings are consistent with facts from suicide research and with an evolutionary view of suicidal behavior. The present research extended these accounts cross-temporally. Analysis of E. L. Thorndike's state-level personal quality scores and standardized birth rates of eminent persons, taken as proxy variables for regional intelligence, along with historical state suicide rates (1913-1924 and 1928-1932) showed that intelligence and suicide mortality across the U.S.A. were already clearly positively related during the early 20th century, suggesting time stability of the effect. Within the U.S.A., the effect is possibly due to state differences in the ethnic composition, which correspond to both suicide rates and intelligence proxies. It is argued that the most parsimonious interpretation of these ecological findings remains that they indeed reflect individual-level effects, that a positive link between intelligence and suicide is entirely compatible with positive overall links between intelligence and health and longevity, and that the ultimate explanative background for the positive link between intelligence and suicide may be provided through the framework of Rushton's differential K theory.     

Development and validation of the sex role conflict scale.

Because the authors found previous attempts at measuring sex role conflict to lack rigor in measurement and interpretation, they sought to develop an instrument for objectively measuring this condition. From a study of an initial group of 102 persons and a follow-up group of 556 persons from Western U.S. urban areas, the authors developed a new, 17-item, Likert-type scale, which they call the Sex Role Conflict Scale (SRCS). They employed factor analysis to arrive at the final 17 items used, and conducted studies of the scale's reliability and validity, correlating its results with previously validated measures of role conflict, job satisfaction, job involvement, and propensity to leave. The authors found correlations between their variables and sex role conflict, and recommend the SRCS for measuring the degree of such conflict experienced by both men and women.     

Working Hours and Life Satisfaction: A Cross-Cultural Comparison of Latin America and the United States

This paper compares the life satisfaction and working hours of Latin Americans and U.S. Americans using the AmericasBarometer and General Social Survey. While there are many common determinants of happiness, hours worked is not among them. Differences in cultural values, especially the distinction between collectivism (familism) and individualism that has long been a foundation of social development theory, may be why married Latin American males are less happy than married U.S. American males when working longer hours. The distinction is not apparent among females or the unmarried.     

The Gender Identity Reflection and Rumination Scale: Development and Psychometric Evaluation

The authors describe the development of the Gender Identity Reflection and Rumination Scale (GRRS), which measures rumination in the context of gender identity among transgender persons. GRRS items were formulated taking into account previous research on rumination, stigma stress, and identity processing. Two national U.S. samples were collected to investigate the psychometric properties of the GRRS, resulting in 3 factors of gender identity rumination: Reflection, Rumination, and Preoccupation With Others’ Perceptions.
