Factors associated with respite care use by families with a child with disabilities

This paper reviews the literature on respite care utilization, describes a respite care program in Arkansas, and reports on a study of utilization initiated by the Arkansas Division of Mental Health Services (DMHS). Among the 89 families qualifying for respite services, 70 consented to participate, and 66 were surveyed in a phone interview. Users (n=54) and non-users (n=12) were compared relative to a variety of staff, child, geographic, and budget differences. Also, respite use was examined relative, to the aforementioned variables based on level of use, (i.e., none, low, moderate, high). There were no differences in use according to age, the number of family members, family income, or needs of the child. A larger percentage of non-use and low use of respite care was evident among those families receiving Tax Equity Fiscal Responsibility Act (TEFRA) benefits. There were no significant differences between races related to perceived barriers to care. Differences in expectations/experiences with respite care among rural and urban groups were limited with rural respondents expressing, concern about travel/distance issues. Overall, the program as a whole received positive ratings by parents, and no clear factors were found to be related to non-use in the small sample (n=12) who did not take advantage of respite services.     

Speed of Lexical Activation in Nonfluent Broca''s Aphasia and Fluent Wernicke''s Aphasia

Rapid, automatic access to lexical/semantic knowledge is critical in supporting the tight temporal constraints of on-line sentence comprehension. Based on findings of “abnormal” lexical priming in nonfluent aphasics, the question of disrupted automatic lexical activation has been the focus of many recent efforts to understand their impaired sentence comprehension capabilities. The picture that emerges from this literature is, however, unclear. Nonfluent Broca's aphasic patients showinconsistent,notabsent,lexical priming, and there is little consensus about the conditions under which they do and do not prime. The most parsimonious explanation for the variable findings from priming studies to date is that the primary disturbance in Broca's lexical activation has something to do withspeedof activation. Broca's aphasic patients prime when sufficient time is allowed for activation to spread among associates. To examine this “slowed activation” hypothesis, the time course of lexical activation was examined using a list priming paradigm. Temporal delays between successive words ranged from 300 to 2100 msec. One nonfluent Broca's aphasic patient and one fluent Wernicke's patient were tested. Both patients displayed abnormal priming patterns, though of different sorts. In contrast to elderly subjects, who prime at relatively short interstimulus intervals (ISIs) beginning at 500 msec, the Broca's aphasic subject showed reliable automatic priming but only at a long ISI of 1500 msec. That is, this subject retained the ability to access lexical information automatically if allowed sufficient time to do so, a finding that may help explain disrupted comprehension of normally rapid conversational speech. The Wernicke's aphasic subject, in contrast, showed normally rapid initial activation but continued to show priming over an abnormally long range of delays, from 300 msec through 1100 msec. This protracted priming suggests failure to dampen activation and might explain the semantic confusion exhibited by fluent Wernicke's patients.     

Toys,spatial ability,and science and mathematics achievement: Are they related?

This review of research examines the possible relationships among children's toy playing habits, spatial abilities, and their science and mathematics achievements. Only studies that made use of United States subjects, aged 3- through 13-years-old, are included in the review. Toy playing habits, spatial ability, and science and mathematical achievement appear sex typed. Males and/or children who maintain a masculine sex role orientation tend to play with a wider variety of toys, exhibit superior spatial skills, and maintain greater science and mathematics achievement scores than females and/or children with feminine sex role orientations.     

Variability in the initiation of articulatory movements in the speech of stutterers and normal speakers

This study was designed to investigate the differences between stutterers and normal speakers in phonatory and articulatory timing during the initiation of fluent utterances of monosyllabic words. Electromyographic recordings of four articulatory muscles and recordings of glottal vibrations were made of repetitive utterances of a series of monosyllabic words by 15 stutterers and 17 nonstutterers. These data were analyzed in terms of average interval times between voice onset and onset of EMG activity and between onset of EMG activity in each articulator and in terms of the intrasubject variability of these durational measures. Results showed that there were no significant differences between stutterers and nonstutterers in average interval times and that stutterers, in general, were significantly more variable in their speech onset timing. Findings are discussed in terms of recent hypotheses concerning the role of timing disturbances as the main source of speech disruption in stutterers.     

Eye movements and visual imagery in free recall

The relationship between eye movements and visual imagery has almost exclusively been studied by treating eye movements as the dependent variable while an imagery task is being performed. In the present experiment three eye-movement treatment conditions were manipulated, within Ss, as the independent variable in order to study their effects on the free recall of nouns which Ss had to store by means of imagery. The imagery-evoking capacity (I) of nouns was varied over three levels within lists of Dutch nouns (Low, Medium and High I). Ss were instructed to generate a visual image to each separate noun under the following treatment conditions: (a) while they looked over and scanned their image as if they were looking at the real object: (b) while they received concurrent visual stimulation from a checkerboard pattern; (c) while they fixated on a target. Reliable, but minor effects of treatment conditions on the recall scores were found. The results were discussed in terms of possible theories about the nature of the relationship between eye movements and visual imagery.     

A stochastic growth model applied to repeated tests of academic knowledge

In the course of the medical program at the University of Limburg, students complete a total of 24 progress tests, consisting of items drawn from a constant itembank. A model is presented for the growth of knowledge reflected by these results. The Rasch model is used as a starting point, but both ability and difficulty parameters are taken to be random, and moreover the logistic distribution is replaced by the normal. Both individual and group abilities are estimated and explained through simple linear regression. Application to real data shows that the model fits very well.     

Anger control in response to verbal provocation: Effects of stimulant medication for boys with ADHD

Although stimulant medication reduces hyperactive children's aggression in naturalistic settings, stimulant effects on anger control have not been demonstrated. We therefore assessed the role of methylphenidate in enhancing response to verbal provocation from familiar peers and from role-playing adults. Twenty-four boys with attention deficithyperactivity disorder (ADHD), aged 6–12, received small-group cognitivebehavioral intervention in anger management skills. During posttraining assessments, the children were randomly assigned to placebo versus. 6 mg/kg of methylphenidate. In the peer provocations, methylphenidate enhanced self-control, decreased physical retaliation, and marginally increased the display of coping strategies. Medication and prompting were minimally beneficial in the delayed, adult-administered generalization assessments. Among the issues discussed are (a) differences between peer and adult provocation and (b) the roles of medication dosage and multimodality intervention for promoting socially competent behavior in children with ADHD.We gratefully acknowledge the Fernald Child Study Center of the University of California, Los Angeles, which provided major support for this research. In addition, we acknowledge the dedication of the small-group trainers, too numerous to mention individually, who led the intervention procedures for the children, and the experimenters who performed the individual provocation assessments. The careful behavior observations of Linda Douglas, Rebecca Eiser, Deborah Gibson, Mike Glenn, Melissa Michaelson, Jon Rafuse, Fauzia Simjee, Leslie Sherman, and Madelin Tundidor were central to the study. Finally, our colleagues Barbara Henker and Carol K. Whalen were instrumental in facilitating all aspects of this investigation.     

DECIDING WHOM TO TELL: EXPECTATIONS AND OUTCOMES OF RAPE SURVIVORS' FIRST DISCLOSURES

In this study, 102 female rape survivors were interviewed regarding their first post-assault disclosure. Qualitative analysis revealed that nearly 75% of first disclosures were to informal support providers and over one third of the disclosures were not initiated by the survivors themselves. Over half of the survivors received positive reactions and less than one third felt the disclosure had a detrimental impact on their recovery. Loglinear analysis suggested that survivors who actively sought help from informal support providers were more likely to receive positive than negative reactions. In contrast, survivors who actively sought help from formal support providers were more likely to receive negative than positive reactions. When disclosure to formal support providers was initiated by the formal support providers themselves, however, survivors received exclusively positive reactions. Implications for future research are discussed.
