Correlations of glucose metabolism and structural damage to language function in aphasia

Studies of aphasic patients using [18F]fluorodeoxyglucose positron computed tomographs have shown areas of metabolic depression in the left hemisphere larger than the area of infarction noted on CT. To evaluate these metabolic differences in relationship to language abnormalities, 11 patients had metabolic scans, CT, and were administered the Boston Diagnostic Aphasia Battery and the Porch Index of Communicative Ability. Correlation analyses were computed between metabolic, CT, and language data. CT demonstrated reliable correlations of speaking, oral reading, and repetition to Wernicke' area, consistent with current anatomic language models, while metabolic data from areas posterior, inferior, and superior to the traditional Wernicke's area and the head of the caudate nucleus also had reliable correlations with aphasic language function. The utilization of both structural and metabolic brain measures may improve our understanding of the anatomy of language as related to aphasia.     

Mental patients as computer operators

Tactics of design are described for programs to be used by chronic psychiatric patients on an accounting task in the maintenance of records of token economies at Creedmoor Psychiatric Center. To address the patients’ cognitive, motoric, and motivational deficiencies, special attention was paid to display features, branching formats, error detection, feedback, and keyboard utilization.     

The effects of an interdisciplinary infant stimulation—parent education intervention program upon infant development

An eight month infant-stimulation/parent-education program was presented to mother-child dyads participating in one of three types of classes: a structured twenty-two session group, an unstructured twenty-two session group, or a structured eleven session group. Infants (2–15 months) in all intervention groups as well as those from a control group were tested three times (pre-test, mid-test, post-test) during the course of the program using the Bayley Mental Test of Infant Development and the Uzgiris-Hunt Ordinal Scales of Psychological Development. Results tend to indicate that the intervention strategy was an effective method of parent education in enhancing infant gains on developmental indices. The results are discussed in relation to a preventative psychotherapeutic model.     

Graduated exposure plus feedback in the treatment of speech anxiety

This study investigated the effectiveness of a graduated exposure procedure, combined with peer feedback, in the treatment of speech anxiety. Subjects were assigned to one of two conditions: (a) graduated exposure/shaping plus feedback or (b) no-treatment control. Results indicated that the graduated exposure/shaping plus feedback treatment group demonstrated significantly greater speech anxiety reduction than the no-treatment control group at post- and follow-up assessment.     

ASSESSMENT OF PREFERENCE FOR VARIED VERSUS CONSTANT REINFORCERS

One method that has been demonstrated to improve the effectiveness of reinforcement is stimulus (reinforcer) variation (Egel, 1980). Egel found that bar pressing increased and responding occurred more rapidly during varied reinforcement than during constant reinforcement when identical stimuli were used across phases for 10 individuals with autism. The purpose of the current investigation was to assess the preferences of 7 individuals for varied presentation of slightly lower quality stimuli relative to constant access to the highest quality stimulus. Varied presentation was preferred over constant reinforcer presentation with 4 participants, and the opposite was true for 2 participants. One participant did not demonstrate a preference. These results suggest that stimulus variation may allow less preferred reinforcers to compete effectively with a more highly preferred reinforcer for some individuals.     

Psychiatric Disorders Associated with Substance Use Among Children and Adolescents: Findings from the Methods for the Epidemiology of Child and Adolescent Mental Disorders (MECA) Study

The relationships between specific quantities and frequencies of alcohol, cigarette, and illicit substance use and substance use (SUD) and other psychiatric disorders were investigated among 1,285 randomly selected children and adolescents, aged 9 to 18, and their parents, from the Methods for the Epidemiology of Child and Adolescent Mental Disorders (MECA) Study. Logistic regressions indicated that daily cigarette smoking, weekly alcohol consumption, and any illicit substance use in the past year were each independently associated with an elevated likelihood of diagnosis with SUD and other psychiatric disorders (anxiety, mood, or disruptive behavior disorders), controlling for sociodemographic characteristics (age, gender, ethnicity, family income). The associations between the use of specific substances and specific psychiatric disorders varied as a function of gender.
