Influence of knowledge and religiousness on attitudes toward organ donation.

There remains a great need for organ donation. Each year thousands of individuals wait for organs to be donated for transplantation. In this study, the Organ Donation Attitude Survey (ODAS) was developed. One hundred ninety undergraduate students (114 women with a mean age of 20.0 and 76 men with a mean age of 20.5 years) enrolled in general education classes at a small midwestern university participated. The present study determined that ODAS is a reliable and valid instrument to assess attitudes regarding organ donation. The data were analyzed by stepwise regression to determine which variables were related to attitudes regarding organ donation. The results indicated the impact of four variables: education regarding organ donation, knowledge of someone who had donated an organ after death, awareness of anyone who received a donated organ, and religious beliefs. These significant variables in the regression analysis explained 24.95% of the ODAS total score variability. The most important results of the present study indicated that the ODAS was psychometrically valid and it could be used to evaluate attitudes regarding organ donation.

Facilitation of internal locus of control in adolescent alcoholics through a brief biofeedback-assisted autogenic relaxation training procedure.

The purpose of the study was to determine if autogenic relaxation training facilitated through biofeedback promotes an increase in internal levels of locus of control. The participants were residents of two Southwest Missouri alcohol treatment centers and ranged in age from 18 to 21 years. Treatment and control groups were compared on their responses on the Drinking Related Locus of Control Scale (DRIE) and fingertip temperature pre- and posttraining. The training was effective in teaching autogenic relaxation as demonstrated by increased fingertip temperature for the treatment group posttraining, while no differences were observed for the control group. Most importantly, the treatment group was not only significantly more internal in their locus of control after training but were also significantly more internal than the control group posttraining. Given that alcoholics are significantly more external in their locus of control than nonalcoholics, and that an internal locus of control implies an individual's belief that he or she has control and is responsible for his or her behavior, autogenic relaxation facilitated through biofeedback may be a very important component in therapeutic intervention for adolescent alcoholics.

Early identification and remediation of phonological-processing deficits in first-grade children at risk for reading disabilities.

The present study assessed 486 first-quarter first graders on their reading and phonological-processing skills and intelligence. Based on this assessment, and using the classification data from Hurford et al.'s (1993) study, 99 children were identified as being at risk for reading difficulties: 53 children at risk for reading disabilities (RD) and 46 children at risk for becoming "garden-variety" poor readers (GV). Half of the RD and GV groups received the phonological-processing intervention. Posttraining assessment indicated that the training procedure not only was effective in increasing the phonological-processing skills of the trained participants, but also increased their reading ability. Both of the RD and GV trained groups benefited from the training. Analyses also indicated that the initial screening device was somewhat less accurate in the present study in identifying at-risk children than in our previous studies (85% vs. approximately 98%, respectively). The results of the present study indicate that it is possible to identify children at risk for reading difficulties and to significantly improve their phonological-processing and reading abilities.

Early identification of children at risk for reading disabilities.

The present study examined the development of phonological and reading skills in 171 students (98 males, 73 females) from the beginning of first grade (Time 1) to the end of second grade (Time 4). Based on their reading and intelligence scores at the end of second grade, these students were placed into nondisabled (ND), reading disabled (RD), or garden-variety poor reading (GV) groups. Although each group made gains in phonological processing, large differences were found between the ND and RD/GV groups. The RD and GV groups performed similarly on many of the tasks. Consistent with the literature, it was found that intelligence does not differentiate between good and poor readers. The most important finding of the present study was that reader-group membership at Time 4 could be very accurately determined from students' Time 1 scores. All of the children in the RD and GV groups were correctly identified, and only 3 of the 148 ND children were misclassified, indicating that children at risk for reading difficulties can be very accurately identified very early in their academic experiences.

An examination of phonemic processing abilities in children during their first-grade year.

The present study examined the development of reading and phonological processing abilities of 209 first graders (118 males, 91 females; mean age = 86.7 months) assessed during the first and last quarters of their first-grade year. The children were arranged into three different groups based on their Time 2 reading and intelligence data (children with and without reading disabilities, and "garden-variety" poor readers). Analyses indicated that the children with reading disabilities and the garden-variety poor readers did not differ significantly on many of the tasks, but both performed differently than the children without reading disabilities. Developmental analyses indicated that all three groups increased their reading and phonological skills; however, the gap between the performance of the children without reading disabilities and the other two groups widened from Time 1 to Time 2. The most important finding of the present study concerned the classification results of the discriminant analysis, which correctly identified the group membership of 207 of the 209 children (99.04% correct).

Training phonemic segmentation ability with a phonemic discrimination intervention in second- and third-grade children with reading disabilities.

The present study examined the possibility that phonemic discrimination training could improve the phonemic segmentation ability of children with reading disabilities. Half of the 32 children with reading disabilities (14 male and 4 female second graders and 10 male and 4 female third graders, with mean ages of 99.2 and 109.7 months, respectively) deficient in phonemic segmentation skills were assigned to the training group, while the other half acted as a nontrained control group. The trained children were successful at significantly improving their performance on the phonemic segmentation task. The control group made no improvement. Requiring children with reading disabilities to make discriminations concerning phonemic information may have helped them discover properties of the phoneme that they previously did not know.

The effect of varying alveolar carbon dioxide levels on free recall.

A recent study suggested that students who have increased minute ventilation receive poorer grades. The present study was interested in determining the role alveolar carbon dioxide (CO2) levels play with cognitive abilities. A free recall task was used to examine list learning under two conditions of alveolar CO2 level: normal and decreased. The results suggested that decreased alveolar CO2 level affect the participant's ability to rehearse and recall information. It was concluded that conditions that reduce alveolar CO2 levels, such as hyperventilation resulting from stress, nervousness, or inappropriate breathing habits, can lead to poorer learning. If these conditions produce a habitual breathing pattern, the academic performance of the individual may suffer.

Ice cream butterfat content by volume as a possible predictor of taste preference.

71 males and 75 females ranging in age from 18 to 61 yr. (M age 20 yr.) ranked three brands of vanilla ice cream for taste preference. The expectation that butterfat content by volume (rather than by weight) would predict taste preference was confirmed in this exploratory study.
