Effects of information on perceptions of stimulant medication efficacy for treatment of attention‐deficit hyperactivity disorder

A study on the perceptions of stimulant medications prescribed for children with attention‐deficit hyperactivity disorder (AD/HD) was conducted. Students, enrolled in introductory level psychology courses at a midwestern university participated voluntarily in the study (N= 36). After viewing a video that simulated the feelings a child with AD/HD experiences, participants were randomly assigned to two treatment groups. The popular information group read an article on AD/HD similar to that which is most often presented to the public. This article included personal testimonials and lacked a discussion of side effects and areas where the medications have not been demonstrated to be efficacious. The scientific information group read a page of information that was compiled from the scientific literature and included both the positive effects, side effects, and areas where the medication has not been demonstrated to be efficacious. All participants then completed a questionnaire regarding their perceptions of the efficacy of the medications. A second scale measured participants' likelihood of recommending the use of stimulant medications for children with suspected AD/HD. Two 2×2 between‐subjects ANOVA's were employed. There were main effects for the type of article that was read, but no main effects for gender of participant. No significant interactions were found. There were no differences found between the gender of participants and their perceptions of stimulant medications based on the reading material presented to them. However, the type of information presented to the participants did influence their view of the efficacy of stimulant medications. In addition, the type of reading material also influenced the participants' view of the safety and recommended use of stimulant medications prescribed for children with AD/HD. © 1999 John Wiley & Sons, Inc.     

Differential effects of stimulant medication on reading performance of boys with hyperactivity with and without conduct disorder

Controversy surrounding stimulant medication, particularly its effects on reading performance, continues to obscure the issue of the use of this drug in classroom situations. The present study emphasized careful differential diagnosis, double-blind and placebo approaches, and curriculum-based dependent measures to address these concerns. Methylphenidate was administered to two groups of boys, ages 8 through 11. The two groups included 27 subjects meeting criteria for attention deficit-hyperactivity disorder but not conduct disorder, known as hyperactive disorder (HD), and 28 subjects meeting criteria for both diagnostic categories, known as hyperactive-aggressive (HA). Only four subjects in each group met a discrepancy criterion for learning disabilities (LD). Methylphenidate was administered to both groups at three levels of dosage, along with baseline and placebo conditions. Dependent measures involved both reading recognition and reading comprehension, equivalent across all conditions. No significant results were found for the group with HD in either reading recognition or comprehension, due largely to unusual placebo reactions. Results were generally in the direction predicted for the group with HA, but only significantly so in reading comprehension, and no dose effect was found on this variable. Implications for reading as a dependent measure of medication effects are discussed.     

Peer Assessment Training in Teacher Education: Effects on performance and perceptions

The implementation of peer assessment receives much attention in teacher education. This paper reports the effects of peer assessment training on the performance of student teachers. Ninety-three student teachers were randomly assigned to control groups and experimental groups. The experimental groups were trained in defining performance criteria, giving feedback and writing assessment reports. This was done through peer assessment tasks that were embedded in a redesigned course. Analyses of data derived from peer assessment reports written by the students showed that the experimental groups surpassed the control groups in the quality of the assessment skill. As a result of the training, students from the experimental groups also scored significantly higher grades for the end products of the course than students from the control groups. The results of the questionnaire showed that all students were significantly more satisfied with the redesigned course.     

Peer effects,motivation, and learning

This paper confirms the existence of peer effects in a learning process with data from an experiment. The experimental setting offers an insight into the mechanisms of peer interaction and provides complementary information to empirical studies using survey or administrative data. The results show that a partner has a motivational effect even before the actual cooperation takes place. The evidence for optimal group composition is not robust. Some of the “better” students improve the performance of their partner but they induce lower motivation.     

Peer tutoring for college students with learning disabilities: perceptions of tutors and tutees

Peer tutoring is a commonly provided support service for students with learning disabilities (LD) in institutions of higher education. A large-scale survey was conducted to evaluate the PERACH peer tutoring project for students with LD at 25 universities, regional colleges, and teacher training colleges in Israel. The purpose of the study was to understand the tutoring process from the point of view of both tutees and tutors with respect to 5 main areas: tutees' needs, focus of tutoring activities, difficulties surrounding the tutoring endeavor, importance of similar study experiences, and satisfaction with the project. It is our supposition that major discrepancies in perceptions are likely to undermine the effectiveness of the tutoring. Similarities and differences in perceptions were identified, and implications that can be useful in guiding service providers are discussed.     

Peer perceptions of students receiving pull-out services in elementary school: A multi-age study

This study examined the peer nominations of 213 children in Kindergarten (90), 3rd grade (58), and 5th grade (65) to examine their perceptions of peers who received pull-out services for unique needs. Using Coie, Dodge, and Coppotelli’s[1982. “Dimensions and Types of Social Status: A Cross-age Perspective.” Developmental Psychology 18 (4): 557–570] protocol for assessing sociometric status in children, the results revealed that peer perceptions of most liked (ML) and least liked (LL) in the classroom were associated with pull-out status, with those students who did not receive pull-out services receiving more nominations as ML than their peers who did leave the classroom for pull-out services. Social impact scores for children who received pull-out services were not significantly different from those of children who did not receive pull-out services, but significant differences were revealed for social preference scores. Implications and avenues for future research are discussed.     

Peer review in the classroom: student perceptions,peer feedback quality and the role of assessment

Abstract

Peer review in the classroom can enhance numerous employability skills such as critical appraisal, writing skills, reflection practices and collaborative experiences. This study takes place over two years and discusses the implementation of a repeating blind peer review cycle across a single semester for final year chemistry students enrolled on a compulsory employability module. The feedback cycle promotes personal reflection through the use of mini-reflective questionnaires. The process was assessed by academic tutors at the resubmission stage and/or the peer feedback stage where the quality of peer feedback was directly assessed. The research investigates the quality of peer feedback, the importance of assessment and student perceptions of what is most useful. Methods include directed content analysis of feedback produced, student opinions and a focus group. Students were capable of offering useable feedback across a range of assessment criteria but tend to focus on the important criteria best aligned to the particular assignment. A range of motivational factors and tactics were noticed but students tended to find reviewing the most beneficial.     

Peer interaction effects in the activation of categorical concepts

This study was aimed at investigating the effects of social interaction in a task involving the utilization of categorical concepts by 7- and 9-year-olds from two contrasting socio-economic backgrounds (upper class and lower class). The task, presented as a guessing game, was performed under two experimental conditions: an individual condition (one subject alone asked his/her partner questions) and a dyadic condition (two subjects formulated questions together to ask two other partners). In both experimental conditions, the «questioned» subjects answered «yes» or «no» to their partner’s (or partners’) questions. Two pre-test and post-test tasks (a nonmember task and a similarity task) involving the same categorical concepts as the training tasks were set up to assess the effects of training condition and socio-economic background on progress. An untrained group of subjects served as the control group. The results showed that the experimental setup was very beneficial for all subjects, regardless of what kind of training they had undergone (individual or dyadic) and what background they came from. These findings provide evidence of the effectiveness of the social regulation at work in both of these experimental conditions (yes/no feedback) for a task where the socially-defined goal to be attained by the subjects is represented in an unambiguous manner.     

The effects of gender and consequence upon perceptions of deceivers

This study examines the impact of gender combinations and consequences of deceptive acts upon perceptions held by uninvolved third party observers. Perceptions examined in this initial study were observer attitudes toward a specific act of deception and the deceiver's credibility and personal qualities. Results indicate the existence of both a gender effect and a consequence effect. Under certain conditions, females appear to be more sensitive to relational deception than males and report more negative attitudes and perceptions of the deceiver's character, competence, and sociability. The consequence for the target impacted both observer attitude toward the specific act of deception and perceptions of deceiver credibility. Paradigmatic research should be designed to yield additional information.     

Children's expectancies and perceptions of adults: effects on rapport

Interpersonal expectancy effects are less thoroughly understood in children than in adults, yet they can have practical implications for children's interactions. To understand better children's expectancies, this study extended earlier work to include expectancies of adults, preexisting (i.e., noninduced) expectancies, and joint effects of expectancies and subsequent perceptions. Children (N = 81) in Grades 4 through 6 (i.e., 9- to 12-year-olds) indicated their expectancies of adults who subsequently interacted with them using a style of either autonomy support (AS) or control (CN). After each interaction, children reported on perceived AS and on rapport. Results indicated that children's expectancies and subsequent perceptions interact to predict rapport, adult AS is associated with increased rapport, and the effect of children's expectancies on rapport is only partially mediated by their perceptions.     

Psychopharmacological intervention. II: Teacher perceptions of psychotropic medication for students with learning disabilities

The perceptions, knowledge, and opinions of 104 teachers of students with learning disabilities regarding medication used with their students were investigated. The students' doctors were perceived as the professionals primarily responsible for making the decision to have the student either placed on or taken off medication. The teachers indicated that global impressions and direct behavioral observations were used to assess the effects of medication but that they would prefer to use behavioral observations and rating scales. Hyperactivity and delusions/hallucinations were perceived as the problems most likely to lead to medication. Less than 15% of the teachers indicated that their professional preservice training had provided them with sufficient information on the use of medication for children with behavior problems, and less than 20% had a similar opinion regarding their inservice training on the same topic.     

Peer assessment effects on the self-assessment process of first-year undergraduates

Peers carry potential in enhancing students’ self-assessment development, but few studies have explored how peer scaffolding is enacted in the process. This qualitative study explores peer assessment effects on the self-assessment process of 11 first-year undergraduates and the factors limiting peer influence. Drawing on the data from students’ journals, follow-up interviews, observations of in-class formative peer assessment activities and teacher interviews, we ascertained that peers could aid the self-assessment process by enriching student understanding of quality, refining subjective judgement and deepening self-reflection. Yet, peer influence could be reduced by distrust, tensions in feedback communication, competition and lack of readiness for peer learning. Implications for effective use of peers in supporting self-assessment development are discussed.     

The effects of prior information upon perceptions of exceptional children

Students in a university special education course were shown three identical videotapes of children in a school setting. The subjects were randomly divided into three groups, each receiving different written background information (“positive,” “neutral,” or “negative”) prior to viewing the videotapes. It was found that the variations in written information had significant effects upon the subjects' perceptions of the children's behavior, and upon the degree to which the children were regarded as able to function successfully in a regular classroom. These findings suggest that attitudes toward exceptional children are influenced by the way in which prior information, such as that contained in a child's educational records, is presented. Teacher and peer acceptance of exceptional children can be increased if information is presented in a realistic and positive manner.     

Peer effects in higher education: A look at heterogeneous impacts

This paper uses data on roommates from two different selective institutions to investigate the effect of peers on first-year performance, with a specific focus on the underlying mechanism. We compare measures of academic ability across student sub-groups by race, income, and gender, and across institutions. Male, minority, and aided students are affected most strongly by their peers. The size and presence of peer effects are dependent on the ability measure used as well as the setting. Standardized estimates suggest ability measured by high school grades have roughly twice the effect of ability measured by SATs. We also test the use of a standardized measure of first-year performance and find more consistent evidence of peer effects across both schools. Our results provide an explanation for the mixed findings in the literature and suggest that the driving force behind peer effects lies in the transfer of general academic know-how rather than in the teaching of specific knowledge or social proximity.     

Peer effects on academic cheating among high school students in Taiwan

Although academic cheating has been found to be a common phenomenon in high schools, few studies investigate how peers influence individual cheating behavior among high school students. In this paper, we estimate the cross-gender and intra-gender interaction effects on academic cheating among high school students in Taiwan. We detect the evidence of male–male and female–female peer interactions on academic cheating. The female–female interaction effect is stronger than the male–male interaction effect. These results imply girls are more influenced by female peers on academic cheating. The cross-gender interactions (male to female, female to male interactions) are not significant. Whereas, we find that all of the social interaction coefficients become insignificant when this model allows for school-specific fixed effects.     

The effects of teachers' verbal behaviors on kindergartners' perceptions of competence

The purpose of this study was to examine changes in kindergartners' perceptions of competence and to determine the effects of teachers' verbal behaviors on these perceptions. A sample of 168 kindergartners from 31 classrooms participated in a pre- and posttest administration of the Pictorial Scale of Perceived Competence and Social Acceptance and three classroom observations. Kindergartners in this study generally reported high perceptions of competence. The drop in perceptions documented in previous research was not found in this study, suggesting that the developmental change occurs after kindergarten. A modest significant correlation between perceptions of competence and both academic skills and teacher ratings indicated that children were developing more accurate judgements. Teachers' verbal behaviors were not related to students' perceptions of competence. In contrast, the amount of praise that students received was related to the instructional style of the teacher and the frequency in which students were criticized was related to their academic skills. Implications for educational practice are discussed. © 1997 John Wiley & Sons, Inc.     

The effects of student personality on perceptions of two-source transformational leadership

This paper examines the role of student personality traits on student perceptions of an instructor’s and community partner’s leader behaviours in a service-learning context. Extant literature does not examine the role of an educator’s leadership in service-learning projects in conjunction with that of a community partner and does not consider the importance of student perceptions of these two sources of leadership. The present study demonstrates that the emergence of transformational leadership is not only an outcome of leaders’ personality and behaviours, as most of the transformational leadership literature suggests, but also to a degree a function of followers’ attributes. Thus, the development of effective transformational leaders must factor in followers’ personality traits. Specifically, the effects on perceptions of leadership of three personality traits were examined. Findings suggest that both agreeableness and conscientiousness correlate with service-learning participants’ perceptions of an instructor’s transformational leadership behaviours, but extraversion did not. Results also suggest that service-learning participants’ perceptions of an instructor’s transformational leadership behaviours correlate with their perceptions of a community partner’s similar behaviours.
