Question 1

Which of the following appears to be most influential on changes that occur over time In the gender distribution in the stuttering population from 2:1 to approximately 4:1 male-to-female ratio:

Accepted Answer

The higher rate of natural recovery from stuttering in girls compared to boys contributes to the shift in gender distribution, resulting in a higher male-to-female ratio over time.

Question 2

Data on the occurrence of stuttering across the lifespan indicate that:

Accepted Answer

The prevalence of stuttering is about 1%, indicating the proportion of people who stutter at a given time, while the incidence is higher, reflecting the number of new cases over time.

Question 3

Which is not true about the incidence of stuttering in various groups?

Accepted Answer

Stuttering is not specifically linked to socio-economic status, and there is no evidence to suggest it is very low in the lowest socio-economic strata.

Question 4

Data on the prevalence of stuttering in African American and European American preschool children (Proctor et.al. 2008) showed that

Accepted Answer

The study by Proctor et al. (2008) found no significant difference in the prevalence of stuttering between African American and European American preschool children.

Question 5

The general tendency for the gender ratio (males to females) in the stuttering population indicates it:

Accepted Answer

The gender ratio in stuttering tends to increase with age, meaning that more males than females continue to stutter as they grow older. This is because females are more likely to recover from stuttering during childhood.

Question 6

The prevalence of stuttering in the population at large is:

Accepted Answer

The prevalence of stuttering in the general population is approximately one percent.

Question 7

Which factor is likely to have the most influence on stuttering prevalence data in a population of college students?

Accepted Answer

Gender is a significant factor in stuttering prevalence, with males being more likely to stutter than females.

Question 10

Accepted Answer

The answer of Most of the available data, especially from...

Question 11

Which of the following age groups is expected to exhibit the lowest incidence of stuttering:

Accepted Answer

Stuttering is most common in early childhood as language skills are developing, typically between ages 2 and 5. By ages 63 to 77 months (approximately 5 to 6 years), many children outgrow stuttering, leading to a lower incidence in this age group.

Question 12

Which of the geographical areas has, by far, the lowest incidence of stuttering:

Accepted Answer

There is no conclusive evidence to suggest that any of these regions have a significantly lower incidence of stuttering compared to others. Stuttering occurs worldwide and its prevalence is relatively consistent across different geographical areas.

Question 13

If a group of 100 individuals reveals a 20% lifetime incidence, they are most likely:

Accepted Answer

The answer of If a group of 100 individuals reveals...

Question 14

The incidence of stuttering among deaf persons appears to be considerably higher than the incidence in the general population because they have greater difficulties monitoring and controlling their speech.

Accepted Answer

Stuttering is less common among deaf individuals because they often use sign language, which does not involve the same speech production processes that can lead to stuttering.

Question 15

In terms of exhibiting stuttering, dizygotic twins will be more similar than monozygotic twins.

Accepted Answer

Monozygotic twins share 100% of their genes, while dizygotic twins share about 50%. Stuttering has a genetic component, so monozygotic twins are more likely to both exhibit stuttering than dizygotic twins.

Question 16

Data concerning the distribution of stuttering in families of people who stutter would seem to suggest that stuttering runs in families due to genetic factors.

Accepted Answer

Research indicates that stuttering often occurs in families, suggesting a genetic component to the disorder.

Question 17

Stuttering can affect one or both languages in bilingual individuals.

Accepted Answer

Stuttering can affect both languages in bilingual individuals, though it may manifest differently in each language.

Question 18

A child identified as a persistent stutterer is likely to have other persistent stutterers in his/her family.

Accepted Answer

Stuttering can have a genetic component, and it often runs in families, suggesting a hereditary link.

Question 19

21^scentury studies have tended to report higher stuttering incidence than was reported in the past, with central figures 8% or higher.

Accepted Answer

Studies in the 21st century have reported higher stuttering incidence rates than in the past, with central figures around 8% or higher.

Question 20

The large difference between incidence and prevalence of stuttering is best explained as the result of differences in experimental procedures.

Accepted Answer

The large difference between incidence and prevalence of stuttering is best explained as the result of differences in experimental procedures. Incidence refers to the number of new cases of stuttering that occur in a given population over a specific period of time, while prevalence refers to the total number of cases of stuttering that exist in a population at a given point in time. The difference between incidence and prevalence can be attributed to the fact that some individuals who stutter may recover from the disorder over time, while others may continue to stutter throughout their lives.
