Sex, drugs and dating make teens feel older

20.06.2007
A Canadian study has confirmed what parents have long suspected: dating, sexual activity and substance use seem to make teens feel older than they really are. And, as adolescents get older, the gap between their chronological age and their self-perceived age widens.

Researchers at the University of Alberta in Edmonton, with assistance from the University of Victoria, surveyed a random sample of nearly 700 adolescents from a medium-sized North American city and asked them questions about dating, sexual experience, smoking, alcohol and drug use. The participants, males and females between 12 to 19 years of age, were also asked how old they felt compared to their same-sex peers. Survey results indicated that, as is typical for teens, the sample felt older than their chronological age.

Kelly Arbeau, a doctoral student in psychology at the University of Alberta and co-author of the study, explained that she and her fellow researchers set out to find what’s behind the discrepancy between how old teens feel and how old they really are.

“We found that specific behaviors do have an effect on adolescents’ self-perceived age,” said Arbeau. “For example, having an older dating partner seems to give a teen a higher subjective experience of age.”

Sexual activity, especially starting at an earlier age, was found to have an important relationship to teens’ subjective experience of age (SEA). “Sexual experience is unequivocally the realm of adult behavior,” Arbeau explained. “So, when teens are having sex and their peers aren’t, it can make them feel more adult, more mature than their non-experienced counterparts.”

Smoking (in boys), higher alcohol use and higher drug use were also related to an older SEA. These results suggest an increasing discrepancy between SEA and chronological age across the teen years as young people experience the normative changes associated with adolescence. People in their 20s feel about the age they are or slightly older, but after age 30 and into old age, the average person has an SEA that is younger than his or her chronological age. Adolescence is the only point in the lifespan during which individuals consistently feel older than they are chronologically.

As for the popular wisdom that girls mature earlier than boys, the results of the study seem to support that, with girls more likely to feel older than are boys. This may shed some light on why companies are more likely to target teen girls than teen boys with products once considered only for adults.

The study appears in the June 2007 issue of the Journal of Adolescence.

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
