Definition[ edit ] Cultivation theory suggests that exposure to media, over time, subtly "cultivates" viewers' perceptions of reality. Gerbner and Gross assert:
Researchers disagree on the exact amount of human transient attention span. Selective sustained attention, also known as focused attention, is the level of attention that produces the consistent results on a task over time. Common estimates of the attention span of healthy teenagers and adults range from 10 to 20 minutes; however, there is no empirical evidence for this estimate.
Attention span, as measured by sustained attention, or the time spent continuously on task, varies with age. Older children are capable of longer periods of attention than younger children. Fatigue, hunger, noise, and emotional stress reduce the time focused on the task. Common estimates for sustained attention to a freely chosen task range from about 5 minutes for a two-year-old child, to a maximum of around 20 minutes in older children and adults.
Measurement[ edit ] Many different tests for attention span have been used in different populations and in different times. Some tests measure short-term, focused attention abilities which is typically normal in people with ADHD [ citation needed ]and others provide information about how easily distracted the test-taker is typically a significant problem in people with ADHD.
Variability in test scores can be produced by small changes in the testing environment. Research[ edit ] In an early study of the influence of temperament on attention span, the mothers of pairs of twins were interviewed periodically about the similarities and differences in behavior displayed by their twins during infancy and early childhood.
The results showed that each of the behavioral variables temper frequency, temper intensity, irritability, crying, and demanding attention had a significant inverse relationship with attention span. In other words, the twin with longer attention span was better able to remain absorbed in a particular activity without distraction, and was also the less temperamental twin.
How well a parent can capture and keep a two-year-old's attention on a toy may be more important than just a pleasant way to pass the time. After the mother returned, the experimenter placed a new toy out of reach of the child, stating that the child could have it in a few minutes after the experimenter returned to the room.
Internet browsing may have a similar effect because it enables users to move easily from one page to another.
Most internet users spend less than one minute on the average website. The professor found that veteran web users had developed "distinctive neural pathways.The middle school students in the study spent an average of hours a day watching TV or playing video games.
A comparison group of college students spent hours daily on the same activities. Dear friends, Christ is Risen! I have enjoyed a much needed break, but I could not fully forget about the blog and a few current events. Many of you have asked me for my reaction to the meeting between Patriarch Kirill and Pope Francis but at the time I decided not to comment about it.

The study is not proof that TV viewing causes attention problems because it may be that children prone to attention problems may be drawn to watching television.
Because this study did not seek to prove a causal link between television and attention span, its researchers can’t draw conclusions about which way the data relationship goes.
The study revealed that each hour of television watched per day at ages increases the risk of attention problems, such as ADHD, by almost 10 percent at age 7.
The study controls for other attributes of the home environment including cognitive stimulation and emotional support.
