Ch. 13: Special Topics in Speech-Language Pathology Flashcards
Psychodynamic Theory
Approach to counseling that views behavior as the product of conflictual interaction between 3 systems: the id, ego, and superego. Anxiety is created when emotions arising from the conflicts among these three system are repressed. Requires resolution of the five psychosexual stages to achieve proper development. Purpose is to make clients conscious of repressed problems and help them to resolve these problems so that the personality can be healthy and whole. (Freud)
Client-Centered Theory/Person-Centered Theory
Approach to counseling that states that clients need acceptance and positive unconditional regard in order to develop congruence between their self-concept and their behavior. Foundation of therapy is an empathetic relationship between client and therapist that allows the client to freely experience and express all of his or her emotions in a completely accepting climate. (Rogers)
Behavioral Therapy
Approach to counseling that focuses one what is observable, with an emphasis on environmental and external influences. All behavior is caused by current environmental stimuli (including states of motivation), past learning, and the genetic/neurophysiological variables. Behavior is shaped and maintained by immediate response. Reinforcement must be given immediately after a particular behavior has occurred. Positive reinforcement increases the chance that a behavior will reoccur. Negative reinforcement can also cause a behavior to reoccur. Behaviors that occur in the absence of reinforcement will be extinguished. Focuses specifically on areas that affect the client’s communication abilities. Permits the creation of specific goals whose attainment can be objectively measured with data. Allows clinicians to measure the success of the counseling relationship. Allows for documentation of behavioral outcomes.
Cognitive-Behavioral Theory
Approach to counseling that suggests that the client’s thoughts are key to his or her feelings and actions. They key variable is the meaning a person attributes to an event. The clinician helps the client focus on the problem, specifically identify the distorted thoughts or cognitions accompanying the problem, and replace them with newer, more rational thoughts that lead to behavior change. Change the client’s thinking → Change the belief system → Change the behavior.
Personalization
The inappropriate assumption of responsibility for an event that the client did not cause.
Rationalization
In this form of resistance, the client provides a logical but untrue explanation of why something has occurred. E.g., a client who stutters may explain away his lack of a social life by saying, “No one will talk to me because I stutter.”
Reaction Formation
Clients who experience this have thoughts or emotions that are shocking and unacceptable to them. Thus, they react with opposite emotions. E.g., the husband of an elderly Alzheimer’s patient secretly wishes his wife would die. In this form of resistance, he sacrifices all his own needs and wants to care for his wife, telling the clinician he loves his wife dearly and could not live without her.
Displacement
The client takes his or her feelings of hostility or anger about a situation and transfers them to a safe object or person. E.g., parents becoming angry with you for writing a (correct) diagnosis on a diagnostic report.
Projection
Clients attribute their own emotions, thoughts, or actions to someone else. E.g., mother says that school administrators never communicate with one another. School administrators said that the mother never communicated with them.
Repression
Clients keep their thoughts and feelings under very strict control, out of view of others. Clients themselves are not aware of these thoughts and feelings, which are below the conscious level.
Suppression
Clients keep their feelings and thoughts highly controlled, but they are consciously aware of those feelings. This form of resistance is the norm in some cultures. It should be viewed as a difference, not a defense mechanism, in those situations.
Tomography/
Laminography
A computerized radiographic method of take pictures of different planes of body structures. Used to scan brain structures and is frequently used as a neurodiagnostic method for people with communication disorders such as aphasia secondary to stroke.
Computerized Axial Tomography (CAT) Scan
X-ray beams circle through segments of the brain and pass through tissue. A camera takes pictures of sections of the structure being scanned. The scanner detects density differences, and a computer analyzes the images generated by the scanning machine and produces pictures of the scanned structures. Can detect hemorrhages, lesions, tumors, and other pathologies. Often used in the diagnosis of neuropathology associated with strokes.
Electroencephalography (EEG)
Neurodiagnostic method that records and measures electrical impulses of the brain through small surface electrodes attached to the scalp. Can show different kinds of brain waves associated with different kinds of activity (e.g., talking, listening, thinking). Indicates cerebral pathology by abnormal electrical activity and is often used to detect seizures.
Magnetic Resonance Imaging (MRI)
Neurodiagnostic imaging technique where the patient lies completely still in a cylinder container. Used to show fine detail in brain and spinal cord structure. Can also be used to provide images of the soft tissues, large blood vessels, and heart. Based on alignment and realignment of nuclei of atoms in the cell when a structure is placed in a strong magnetic field. Variations introduced in the amount of magnetic radiation will cause alignment and realignment. Such changes produce electromagnetic signals, which a computer analyzes to produce images of the structure. Sometimes detects lesions missed by CT scans. Expensive. Patients may have difficulty tolerating it.
Positron Emission Tomography (PET)
Neuodiagnostic procedure that is a type of emission computed tomography that allows imaging of metabolic activity through measurements of radioactivity in the section of the body being viewed (e.g., the brain). The patient is injected with a radioactive substance that spreads throughout the brain. The amount of radioactivity is then scanned and observed differences in the amount of radioactivity suggest different rates of cerebral metabolism. Lower than normal metabolic rate suggests neuropathology. If the patient is suspected of having cerebral dysfunction secondary to a stroke, for example, these scans can be helpful by evaluating the function of blood flow and brain metabolism (whereas MRI and CAT scans only evaluate structure).
Single-Photon Emission Computed Tomography (SPECT)
Neurodiagnostic procedure that evaluates the amount of blood flowing through a structure. Also known as regional cerebral blood flow (rCBF). Spreads throughout the cerebral hemispheres and enters the bloodstream. A scanner detects radiation uptake in cerebral blood, and a computer calculates the amount of blood flow in given regions and displays variations in blood flow with different flow colors. Helpful in diagnosing cerebral lesions associated with various Neuropathologies causing communication disorders.
Videofluroscopy
A radiologic method of examining movement of internal structures and recording the movement patterns for assessment and diagnosis. It is useful in assessing the functions of the velopharyngeal mechanism, VF, swallowing, and respiratory movement. X-rays are transmitted through the tissue under observation. The soft tissue is coated with barium with the help of a nasal spray and observers can have multiple views of the structures (e.g., frontal, lateral, base, and oblique views of the velopharyngeal mechanism) and their movements. The images are shown on a phosphorescent screen and recorded on a videotape for later examination and diagnosis. Often used to assess swallowing function in patients with confirmed or suspected dysphagia.
Craniofacial Anomalies
Abnormalities of the structures of the head and face. Congenital and typically due to genetic factors.
Cleft
An opening in a normally closed structure.
Palatal Clefts
Various congenital malformations resulting in an opening in the hard palate, the soft palate, or both. Due to disruptions of the embryonic growth processes resulting in a failure to fuse structures that are normally fused.
Microforms
Minimal expressions of clefts, including a hairline indentation of the lip or just a notch on the limb.
