Q

Cerebral Dominance Theory

A

According to this theory, persons who stutter (as a group) are less likely than their fluent peers to have developed unilateral cerebral dominance. They are often ambidextrous. Thus, these people stutter because of their lack of unilateral dominance. Known to be questionable.

Q

Silent Prolongations

A

An articulatory posture held for a duration longer than average but with no vocalization. E.g., the articulatory position for producing the /p/ sound in the word ‘pot’ may be held too long. Such postures are usually associated with increased muscular tension.

Q

Prevalence

A

Determined by counting the number of individuals who currently have a disease or disorder. Involves a head count at any given point in time. Does not make a predictive statement. Less expensive and time consuming. Head counting often underestimates this by missing those who have not received clinical services.

Q

Stuttering

A

Begins as an increase in the frequency of dysfluencies (may be sudden or gradual). Typically judged to be 5+% of speech as dysfluent to be considered this. Typically begins in early childhood (3 – 6 years). Adult onset is rare. Lifetime expectancy is 5%. Incidence is 1%. Prevalence is higher in African Americans. Occurs more commonly in males (3:1 ratio in younger grades, 4:1 ratio in higher grades). Familial prevalence is estimated to be 3x higher than the general population. Prevalence is higher in people with developmental disabilities and people with neurological impairment (especially brain injury or epilepsy). Lower prevalence in the D/HOH community.

Q

Spontaneous Recovery from Stuttering

A

Disappearance of stuttering without professional help. May be associated with an inadvertent use of certain techniques. Some studies suggest that the rate of this is 60%, others believe it is 30 – 35%. It is not possible to predict whether this phenomenon will occur in a particular child.

Q

Stuttering Associated Motor Behaviors

A

Number and severity of these behaviors may vary. May be accidentally reinforced. Not crucial for diagnosis. Include:

  • Excessive muscular effort
  • Various facial grimaces
  • Various hand and foot movements (e.g., wringing the hands, tapping the foot)
  • Rapid eye blinking
  • Knitting of the eyebrows
  • Lip pursing
  • Rapid openings and closings of the mouth
  • Tongue clicking
24
Q

Stuttering Associated Breathing Abnormalities

A

May be part of the stuttering symptom process. Not crucial to diagnosis. Do not suggest an inherent respiratory disorder. Include:

  • Attempts to speak on inhalation
  • Holding breath before talking
  • Continued attempts to speak even when the air supply is exhausted
  • Interruption of inhalations by exhalations and vice versa
  • Speaking without first inhaling a sufficient amount of air
  • Rapid and jerky breathing during speech
  • Exhaling puffs of air during stuttered speech
  • Generally tensed breathing
25
Q

Negative Emotions Associated with Stuttering

A

Are not necessary for diagnosis, but may help process. Include:

  • Anxiety and apprehension about stuttering
  • Fear of certain speaking situations
  • Frustration in efforts to communicate
  • Possibly a sense of humiliation in certain difficult speaking situations or some hostility toward certain speakers
26
Q

Difficult Speaking Situations

A
  • Speaking with strangers and formal audiences
  • Speaking with people at counters where services or products are bought
  • Speaking on the telephone
  • Ordering in restaurants
  • Speaking to authority figures
  • Self-introductions
  • Introductions of other people
27
Q

Loci of Stuttering

A

Refers to the locations in a speech (or oral reading) seqeucne where stutterings are typically observed. In the speech of adults and school-age children who stutter, stuttering is more likely to occur:
- With consonants than with vowels
- On the first sound or syllable of a word
- On the first word in a phrase or sentence
- On the first word in a grammatical clause
- On longer words
- With less frequently used words
- On content words
For preschool children, loci are the same as for adults, but with one exception: Tends to occur most on function words (especially pronouns, conjunctions, and prepositions). This contrasts with the adults and school-age children who typically stutter more often on content words than on function words. Preschool children also tend to use whole-word repetitions.

28
Q

Stimulus Control

A

Most variations found in stuttering are due to variations in stimuli. Such patterns suggest a strong environmental control. A few important phenomena that suggest strong stimulus control are adaptation, consistency, adjacency, and audience size.

29
Q

Adaptation Effect

A

Systematic reduction in the frequency of stuttering when a short printed passage is repeatedly read aloud. The amount of reduction in stuttering is the greatest during the first few oral readings. The magnitude of reduction is progressively less on subsequent readings of the same passage until the amount of reduction is negligible. The greater the time interval between readings, the less the degree o adaptation. No transfer of adaptation from one passage to another. A temporary pheonomenon. Silent reading of a passage does not produce greater adaptation when the same passage is subsequently read orally. Lipped or whispered reading may reduce stuttering to some extent. Less severe stuttering tends to adapt more than severe stuttering. Both children and adults, those who stutter and those who do not, show adaptation. Great deal of individual difference. Due to a deconfirmation of the expectancy of stuttering, a reactive inhibition (fatigue), fear reduction, and to the rehearsal effect.

30
Q

Consistency Effect

A

The occurrence of stuttering on the same word or loci when a passage is read aloud repeatedly. Opposite of the adaptation effect, in a sense. About 65% of stuttering in given individuals may be consistent (stuttering tends to occur on the same words or loci in repeated readings). Consistency remains when subjects reread a passage after weeks of interval.

31
Q

Adjacency Effect

A

The occurrence of new stuttering on words that surround previously stuttered words. A striking phenomenon of stimulus control. This effect is studied by having a subject read a passage aloud multiple times, blotting out or otherwise concealing the words on which stuttering occurs, and then having the subject read the passage again to note the occurrence of new stuttering. In several subjects, words that were fluently read during earlier readings were eventually stuttered. The newly stuttered words were often adjacent to those blotted out (previously stuttered words). This effect is evident in adults and children who stutter. May be horizontal or vertical.

32
Q

Audience Size Effect

A

Refers to the observation that the frequency of stuttering increases with an increase in audience size. Characterized by:

  • A marked decrease in stuttering when there is no audience and the person is speaking to themselves (monologue)
  • A corresponding increase in the amount of stuttering with a systematic increase in the number of listeners
  • A reduced amount of stuttering when a listener’s hearing is visibly masked
  • A greater amount of stuttering when listeners can hear the person who stutters than when they can only see the person who stutters.
33
Q

Laryngeal Dysfunction Hypothesis

A

States that suttering is due to aberrant laryngeal functions. Etiology may be defective neuromotor control of the laryngeal mechanism, as no local laryngeal pathology has been documented in people who stutter. Evidence for this hypothesis includes:

  • Slightly delayed voice onset time (VOT)
  • Increased tension in the laryngeal muscles
  • Aberrant muscle behavior during stuttered speech
  • Excessive laryngeal muscle activity during stuttered speech
34
Q

Voice Onset Time (VOT)

A

Measured by giving a visual or auditory signal to produce a simple vocal response (e.g., saying “ahhh”) and measuring the time between the offset of the stimulus and the onset of the vocal response. Documented delay is in milliseconds and fades with repeated trials.

35
Q

Operant Behaviors

A

A behavior that can be changed by changing its consequences. Learned behaviors.

36
Q

Diagnosogenic Theory of Stuttering

A

States that when parents punish a child’s normal nonfluencies, the child develops anticipatory, apprehensive, and hypertonic avoidance reactions that are indeed stutterings.

37
Q

Brutten and Shoemaker (1967)

A

Proposed that stuttering consists of fluency disruption due to classically conditioned negative emotion.

38
Q

Johnson (1959)

A

Viewed stuttering as an avoidance behavior. Proposed the diagnosogenic theory. Asserted that stuttering is a cultural phenomenon. Believe that people did not stutter in cultures that did not emphasize fluency.

39
Q

Sheehan (1970)

A

Viewed stuttering as approach avoidance. Believed that a person’s stuttering person’s hesitations and repetitions indicate a conflict between a desire to approach speaking situations and an equally strong desire to avoid them. Difficult to measure. Fluent speech is possible when the drive or desire to speak is stronger than the drive to avoid speech. When the drive to avoid speech is the stronger of the two, the person does not talk at all. However, when the two rives are at equal strengths, stuttering results.

40
Q

Bloodstein (1995)

A

Proposed that stuttering is essentially a response of tension and fragmentation in speech. Stuttering is not unlike normal dysfluency, though it is typically greater in quantity and more disruptive in quality. Such a response of tension and fragmentation may come about because of a child’s belief that speech is a difficult task. Thinks that stuttering may have many origins, most of them related to various kind of severe communication pressure that leads to repeated communicative failures (anticipatory struggle hypothesis).

41
Q

Anticipatory Struggle Hypothesis

A

Hypothesis proposed by Bloodstein (1995), stating that stuttering may have many origins, most of them related to various kinds of severe communicative pressure that leads to repeated communicative failures.

42
Q

Demands and Capacities Model

A

States that stuttering can result when a child faces demands for communication that he or she cannot meet because of limited capacities.

43
Q

Psychological Methods of Treatment for Stuttering

A

Methods involve the assumption that stuttering is a psychological disorder with underlying unconscious psychological conflicts or that stuttering and psychological problems coexist. No strong evidence that this kind of counseling, offered exclusively, is effective. SLPs often use this in conjunction with other treatment methods. Psychological treatment consists of attempts to solve those problems. The somewhat varied methods of treatment include:

  • Discussion of psychological problems associated with stuttering
  • Discussion of feelings, emotions, and attitudes associated with stuttering
  • Discussion and resolution of potential psychological conflicts, unconscious psychosexual conflicts, and various kinds of negative reactions
  • Reeducation of the client about a more realistic and rational approach to the stuttering problem
44
Q

Fluent Stuttering Method/Stutter-More-Fluently Approach

A

Stuttering treatment approach developed by Van Riper (1973). The goal is to obtain more fluent (less abnormal) stuttering. Rarely establishes normal fluency, but does modify stuttering. Relapse of stuttering may be a problem. This method involves the following steps:

1) Teaching stuttering identification
2) Desensitizing the client to his or her stuttering
3) Modifying stuttering (cancellations, pull-outs, preparatory sets)
4) Stabilizing the treatment gains
5) Counseling the client

45
Q

Cancellations

A

Pausing after a stuttered word and saying the word again with easy and more relaxed stuttering.

46
Q

Pull-Outs

A

Change in stuttering midcourse. E.g., by slowing down and using soft articulatory contacts instead of blocking on sounds or words)

47
Q

Preparatory Sets

A

Changing the manner of stuttering so that the client produces less abnormal stuttering.

48
Q

Fluency Shaping/Speak-More Fluently Approach

A

This approach to stuttering aims to establish normal fluency (not fluent stuttering). Teaching the various skills of fluency (e.g., appropriate management of airflow to produce and sustain fluent speech, slower rate of speech, and gentle onset of phonation) is the main treatment task. Can generate slow, deliberate, and somewhat unnatural-sounding speech. Relapse is common. Treatment targets include:

  • Teach airflow management
  • Teach gentle, soft, relaxed, and easy onset of phonation, beginning after the initiation of exhalation
  • Teach a reduced rate of speech through syllable prolongation with no pauses
  • Implement maintenance strategies (e.g., teaching self-monitoring skills and training family and friends to monitor and reinforce fluency in natural settings over time)
  • Reshape normal prosodic features
49
Q

Fluency Reinforcement Method

A

A simple method that works with many young children is to positively reinforce fluent speech in naturalistic conversational contexts. This method can be combined with such targets as reduced speech rate. In this method, the clinician:

  • Aranged a pleasant and relaxed therapeutic setting
  • Evokes speech with the help of picture books, toys, and other play materials
  • Positively reinforces the child for fluent utterances with verbal praise, tokens, or both
  • Frequently models a slow, relaxed speaking rate that assures stutter-free speech
  • Reshapes normal prosody if a slower rate is an added target
50
Q

Delayed Auditory Feedback Treatment

A

When a stuttering person hears his or her own speech with a fraction of a second’s delay, most of the dysfluencies are reduced. Main advantage of this technique is its capacity to induce a slower rate of speech. In this method:

  • Clinician uses DAF machine that allows for variable delays
  • Determines a client-specific duration of delay that assures stutter-free speech
  • Has the client practice stutter-free speech for varying lengths of time to eliminate stutterings
  • Fades the delay in gradual steps to reshape the normal prosody while maintaining fluency
51
Q

Masking + DAF Treatment

A

Method of treatment for stuttering. Used has decreased over the years. Patients may adapt to noise. Treatment includes:

  • Clinician determines a minimum level of auditory masking that induces stutter-free speech
  • Has the client practice stutter-free speech for variable lengths of time, depending on the client’s progress
  • Fade the masking noise to reshape normal prosody while maintaining fluency
52
Q

Direct Stuttering Reduction Methods

A

Methods of treatment that seek to reduce stuttering directly, without teaching specific fluency skills or modifying stuttering into less abnormal forms. To reduce stuttering directly, behavioral methods of time-out or response cost may be used.

53
Q

Time-Out/Pause-and-Talk

A

In this method, the person who stutters is taught to pause after each dysfluency and then resume talking. Can establish natural-sounding fluency. Preferred for older children and adults. The specific procedures include the clinician:

  • Saying “stop” or giving other signals (e.g., a light that comes on) to pause after each dysfluency is observed and making sure that the client completely ceases talking
  • Avoiding eye contact with the client for 5 seconds
  • Reestablishing eye contact after the time-out duration and letting the client continue his or her speech
  • Maintaining eye contact, smiling, and employing other social reinforcers for fluent speech
54
Q

Response Cost

A

In this method, for every instance of stuttering, the clinician takes away a token, that is being awarded for every fluent production. There is a variation of this procedure in which a bunch of tokens are initially given to the client, and a single token is withdrawn for each dysfluent production; this variation is not recommended. Most of the positive evidence is related to the classic procedure of giving tokens for fluency and taking it away for dysfluency. Can establish natural-sounding fluency. Preferred for preschoolers and younger children. The specific procedure includes:

  • Reinforcing the client for every fluently spoken word, phrase, or sentence with a token that is backed up with other kinds of reinforcers; the client exchanges the tokens for another reinforcer at the end of the session
  • Taking a token away in a matter-of-fact manner immediately following a stuttering or at the earliest sign of it
  • Progressing from words and phrases to conversational speech
  • Fading the tokens when fluency is sustained at 98% or better across three or four sessions and maintaining frequency with verbal praise alone
55
Q

Neurogenic Stuttering

A

A form of fluency disorder associated with documented neuropathology. Other neurogenic speech disorders (e.g., apraxia or dysarthria) or language disorders (e.g., aphasia) may or may not be present. Common etiological factors include bilateral brain damage, cerebral vascular disorders that cause strokes and head trauma, extrapyramidal diseases (especially Parkinson’s), progressive supranuclear palsy, brain tumors, brain surgery (including bilateral thalamotomy), seizure disorders, dementia, and drug toxicity (especially from drugs prescribed for asthma, depression, schizophrenia, and anxiety). Characteristics include evidence of neuropathology, adult onset of stuttering, and a generally increased rate of dysfluencies is common. Not associated with social/emotional/self-esteem issues, as is common in childhood-onset stuttering. Signs include repetitions of medial and final syllables in words, dysfluent production of function words, dysfluencies in imitated speech, and rapid speech rate.

56
Q

Cluttering

A

A disorder of fluency characterized by rapid but disordered articulation, possibly combined with a high rate of dysfluencies and disorganized thought and language. Tends to coexist with stuttering. Causes are unknown. Reducing rate of speech usually improves clarity and fluency. Increasing awareness via audio is helpful. Very little research on this topic. Maintenance is a prominent problem after therapy. Characteristics include:

  • Impaired fluency with excessive amounts of dysfluencies
  • Rapid repetition of syllables, along with other forms of dysfluencies
  • Rapid but disordered articulation resulting in indistinct (unintelligible) speech
  • Clearer articulation and improved intelligibility at a slower rate of speech
  • Omission and compression of sounds and syllables
  • Jerky or stumbling rhythm
  • Monotonous tone
  • Spoonerisms
  • Reportedly, a lack of personal concern about or reduced awareness of one’s speech problem
57
Q

Spoonerisms

A

Unintentional interchanges of sounds in a sentence. E.g., many thinkle peep so instead of many people think so)

  • Lack of anxiety about or negative reactions to one’s speech difficulties
  • Disorganized thought processes (a controversial feature)
