A Few Facts About… Conjunctions

Conjunctions are an important method of extending sentence length and complexity, because they are a common method of joining words or parts of sentences together. Coordinating conjunctions join independent clauses (as well as words and phrases), while subordinating conjunctions can join both dependent and independent clauses (as well as words and phrases).
The acquisition and frequency of conjunctions have both been studied extensively. Among the findings are that the word and often initially takes the role of other conjunctions (Bloom et al., 1980; Scott, 1988; cited by Owens, 1996). The conjunctions but, so, or, and if soon are acquired in typically developing children to serve functions that and isn’t as easily able to achieve. Conjunctions like because then develop to express not only a relationship between sentence elements, but additionally a temporal sequence. According to one estimate, by the time a normal child’s mean length of utterances reach 5.0 (at an average age of 4 to 5 years), 20% of the sentences they use in spontaneous speech contain embedded or conjoined clauses (Paul, 1981).
Language itself doesn’t require conjunctions, but effectively communicating advanced ideas usually does. As with other language modalities, conjunctions exist because they assist. We use them to achieve a goal. Just try giving a reason for something without using the word because, or try describing the time relationship between two completed events without using conjunctions such as before, after, or then. It can be done, but much less effectively.
Generally, developmental order of conjunctions is determined by the complexity of the relationship the conjunction serves. Conjunctions appear frequently in assessments such as the CELF, CASL, OWLS, and SPELT. Also, Conjunction Junction is a timeless piece of art.
A Few Facts About… Incidental Teaching

Incidental teaching involves manipulating a student’s environment to promote the natural use of educational objectives. While it can be used for a variety of language goals, incidental teaching is particularly effective in promoting initiation. Incidental teaching can be looked at as having four main features:
- The environment is arranged to set occasion for student response
- Teacher waits
- If necessary, student is prompted
- Student response
The reinforcer is whatever the child needs or wants, such as crayons, juice, or a toy. Incidental teaching contrasts with discrete trial teaching, in that while the one encourages responses, the other expects it. Each has its place, and each is better at teaching different skills.
Planning, prompting, and waiting are three critical aspects of incidental teaching. Planning may start with an observation of a child’s current initiation level, as well as determining child’s unique interests. Ways that low functioning children initiate include looking at desired objects, moving toward them, pointing, grabbing, or taking care-giver’s hand. When prompting, the child should be encouraged to produce a slightly more complex language skill than the current ability, using a developmental hierarchy. When waiting, 3-5 seconds between the event and response is often the most effective interval between prompts.
Incidental teaching is often thought of as “sabotaging the environment.” Some specific examples of how to do this include…
- controlling access to materials
- using items of special interest
- setting up repetitive routines
- starting a favorite activity, and then stopping
- looking at materials, then student, then pausing

Following Directions

One of the most common complaints of teachers and parents involves difficulty with following directions. So, how do we help these kids? Despite its prevalence, there often is a lack of a coherent strategy of dealing with direction following, and its close cousin, language processing. Many things are needed to follow directions – thus, addressing these difficulties should often start with first finding manageable components, before then combining these components in ways that look like the directions themselves.
Following directions involves using short term memory to hold known information while manipulating this information using language. Some types of words appear more frequently in directions than others – conjunctions, negatives, adjectives, and prepositions, for example, are often used in directions. Nearly every test item on one of the most commonly used assessments of following directions, the CELF-4’s Concepts and Following Directions subtest, uses some combination of conjunctions, negatives, and prepositions. These concepts are particularly critical in academic directions. The ability to follow any specific direction depends upon the ability to comprehend the specific words within the direction. Not all one step directions are created equal. For example, a one step direction containing a negative is often more difficult than one with a similarly placed adjective.
Here is an example of how a developmental hierarchy might look for direction following:
Obviously, following directions also requires aspects outside the domain of language, such as motivation, interest, and attention. Increasing proficiency in language should provide a natural boost to these overlapping aspects.

A Few Facts About… Selective Mutism
January 16, 2009 at 12:31 pm | In A Few Facts About... | 2 CommentsTags: facts, language, research, selective mutism, therapy
The very existence of selective mutism demonstrates the significance of expectation in the communication process. Selective mutism occurs when the communication expectations of a situation overwhelm a child’s perceived capabilities. The resulting anxiety results in selective mustism - an inability to talk in one setting with an ability to talk in others. An often preferred method of treatment is for a team consisting of a psychotherapist, speech-language pathologist, parent, and teacher to gradually overcome situational anxiety with therapuetic means. Some selective mutism facts include…
- While estimates of a decade ago and earlier pegged selective mutism as relatively rare, recent studies have suggested that the true prevalence has been underestimated. Some of these studies have suggested that selective mutism may be as common as other widely known childhood disorders, such as autism and tourette’s disorder. This link at selectivemutism.org has some great additional info.
- While childhood trauma has long been blamed, researchers have identified a wide variety of possible etiologies, including depression, obsessive-compulsive disorder, and social phobia. It is widely believed that many children with selective mutism have concomitant language disorders, although the mutism makes these disorders extremely difficult to diagnose.
- According to Dr. Elisa Shipon-Blum, the executive director of selectivemutism.org, “the majority of SM children do not overcome SM.” In an interview here at shykids.com, many of these kids grow into adolescents and adults with extreme social anxiety problems. In this interview Shipon-Blum elaborates on the problems too often caused by taking a wait and see approach.
- There are some good blogs by individuals affected by selective mutism, sharing their memories of SM in their lives. Check out Selective Mutism – My Memories for a really good, frequently updated blog by a man that has had selective mutism. For a blog done by parents, see The blog on Selective Mutism.
A Few Facts About… Negation
December 1, 2008 at 12:01 pm | In A Few Facts About..., Uncategorized | 2 CommentsTags: comprehension, negation, negatives, syntax
One of the most common causes of difficulties in comprehension and following directions is specific difficulty with understanding varied syntactic negative forms. Anything that can be said can, if necessary, be negated. When this occurs, it adds a layer of complexity and difficulty. Some facts:
- There are basic negatives (e.g. no, not, never), negatives that affect varied tense (e.g. do not, did not, didn’t, don’t, won’t, etc.), and negatives in questions (e.g. “Won’t you..” “Can’t you..”, “Wouldn’t you…”).
- Advanced negation requires increasing demands upon working memory, both with comprehension and production. Negative prefixes, such as un-, dis-, and non- may be difficult for advanced language learners.
- The specific negative word a child uses may reflect the specific manner in which a parent uses negation to control behavior. Some parents use no frequently, while others employ don’t (Owens, 1996). Parenting advice often encourages use of positive discipline (e.g., “Walk”, instead of “Don’t run.”) which may affect children’s comprehension of negation. Children who hear both positive and negative versions of the same request may be predisposed to earlier learning of the concepts of negation and opposition.
- Children often simplify sentences with negation by eliminating subjects, and putting the simple negative form prior to the verb (L. Bloom, 1970). Thus, an intended sentence such as “Mommy no go bye-bye.” may initially be produced as “No go bye-bye.”
A Few Facts About… Verb Tense

Tense allows us to more effectively communicate information related to when something occurs, occurred, or will occur, as well as more effectively understand if the occurrence has been completed, is in progress, or will occur continuously. Some key points include:
- Research suggests that omission of tense marker (zero marking) is the most prevalent kind of tense error in children with SLI (Marchman, Wulfeck, Weimer, 1999).
- Different languages use various techniques to express differences in tense. Latinate languages, in particular, use a variety of morphological endings to express when something happens (David Crystal, 1995).
- English only uses three morphological endings: -s, -ed, and -ing. Other tenses are communicated through irregular forms, auxiliary verbs, and adverbs.
A Few Facts About…Ellipsis
September 24, 2008 at 10:58 am | In A Few Facts About... | Leave a CommentTags: ellipsis, elliptical clauses, grammar, prepositions
Ellipsis occurs when a nonessential word is omitted from speech or writing. This happens more frequently than most people realize, and it is the source of much confusion when learning oral language or written language (i.e. reading). An example: “I knew (that) I needed to speak up.”
- Ellipsis is common in clauses with relative pronouns, as in the above example or in this example: “There’s the place (where) I went to school.”
- Ellipsis is also common with prepositions, e.g. “Give (to) me a kiss.” or “Call (for) him a cab.”
- The inclusion of these prepositional phrases or relative clauses may be considered technically correct, but redundant nearly to the point of being superfluous.
- The existence of ellipsis is evidence for the notion that language is more convention based than rule based. We do what works best, even when it seems to defy grammatical rules. As with every other structure in language, ellipsis exists because it assists.
- (An ellipsis is a punctuation symbol (…) used to indicate omission.)
A Few Facts About… The Spacing Effect
September 8, 2008 at 11:17 am | In A Few Facts About... | 1 CommentTags: learning, spacing effect
The spacing effect is a well supported finding in learning research that exposure to a material over time supports memorization. Some facts…
- The best time to reinforce previous learning is at a point just before forgetting takes place. This point varies from person to person. It also varies depending upon what is being learned.
- The time interval that a fact is remembered increases with repeated exposure.

-
The spacing effect has been used to create software to assist learning, as mentioned in this article from Wired magazine and here. Before that it’s lack of application had frustrated social scientists, as mentioned on this psychology website.
-
The spacing effect has been known for more than a century.
-
It has been documented in other species.
A Few Facts About… SLI (Specific Language Impairment)
August 11, 2008 at 11:47 am | In A Few Facts About..., Language Disability | Leave a CommentTags: SLI Specific Language Impairment research few facts
SLI, the common abbreviation of Specific Language Impairment, is usually defined as a language impairment of unknown etiology in the presence of normal cognition. In layman’s terms, these are kids with a language problem and no one knows why. Some (IMO) interesting tidbits are:
- SLI occurs in about 7% of the general population (Tomblin et al, 1997)
- It is more prevalent in males than in females (Flax et al, 2003)
- It is widely acknowledged that individuals with SLI commonly experience learning difficulties of a comparable magnitude across all domains, including mathematics (Arvedson, 2002; Donlan and Gourlay, 1999; Fazio, 1996)
- “ “… and literacy (Bishop and Adams, 1990; Catts, Fey, Tomblin, and Zhang; Flax et al 2003)
SLI seems to be a term more prevalant in the speech pathology community than elsewhere. Because I like to interject my opinion occasionally, I’ll do that here, at the end of this post. There are many possible causes of SLI, including environmental, motivational, and perhaps, genetic.
