Patients diagnosed with Autism Spectrum Disorder, show impaired integration of information across different senses. The processing-level from which this impairment originates, however, remains unclear. We investigated low-level integration of auditory and visual stimuli in subjects with Autism Spectrum Disorder. High-functioning adult subjects…

Drawing on the theory of documents representation (Perfetti et al., Toward a theory of documents representation. In: H. v. Oostendorp & S. R. Goldman (Eds.), "The construction of mental representations during reading." Mahwah, NJ: Erlbaum, 1999), we argue that successfully dealing with multiple documents on the World Wide Web requires readers to…

The main goal of this study was to examine the effect of written exposure on generalized anxiety disorder (GAD)-related symptoms in high worriers. Thirty nonclinical high worriers were randomly assigned to either a written exposure condition or a control writing condition. Self-report measures were used to assess worry, GAD somatic symptoms,…

A secondary school for children with Moderate Learning Difficulties had requested assistance from psychological services for pupils that the school felt were experiencing poor motor-coordination and in some cases low self-esteem. An intervention programme for children with dyspraxic type difficulties (Portwood, 1999) was proposed as a suitable…

The introductory freshmen electromagnetism course at MIT has been taught since 2000 using a studio physics format entitled TEAL--Technology Enabled Active Learning. TEAL has created a collaborative, hands-on environment where students carry out desktop experiments, submit web-based assignments, and have access to a host of visualizations and…

The prevalence of deception and failure to obtain consent in educational research was studied. Articles in two journals that regularly publish educational research were examined. The journals were Volume 17 (1980) of the American Educational Research Journal and Volume 13 (198) of the Journal of Learning Disabilities. Only 54 articles listed in…

This study was designed to answer two questions: (1) Is the systematic desensitization of test anxiety effective with secondary school students?; (2) Is relaxation per se as useful a technique as systematic desensitization? High test anxious secondary-school students were assigned to one of two experimental conditions, desensitization or…

The comprehension of aurally-presented narrative passages by fourth-grade children as a function of listening rate and performance on 11 predictor variables was investigated. The predictor tests included: PPVT, Otis Intelligence Test, MAT, Listening Comprehension, Digit Span, Coding, Auditory Attention Span, Clerical Speed, Perceptual Speed,…

Kindergarten children were randomly assigned: free play, make-believe, imitation, and control. Given an alternate-uses test (paper towel, match box, paper clip, and screwdriver), free play and make-believe subjects produced significantly more nonstandard responses for paper clip than control subjects and make-believe subjects more than free play…

Experiments where participants are randomly assigned into experimental and control groups are often regarded as the ideal approach to evaluation of labor force policies. This paper shows that such design can yield misleading and incomplete information. It proposes alternate designs that permit estimation of marginal as well as average program…

This booklet contains questions and answers about random assignment in program evaluation and intervention research. The main purpose of program evaluation research in education is to determine whether programs help the students they are designed to serve and whether new ideas for education programs still under development are worthy of extension…

Control subjects completed Book IV of the Edwards Personality Inventory under instructions to be honest while experimental subjects were instructed to fake so as to make an excellent impression while also concealing their faking. Differences between group means were small. (Author/EK)

The effects of in-service training programs on their participants are evaluated. (CK)

The advantages and assumptions of analysis of covariance (ANCOVA) and an alternative approach to ANCOVA which uses simultaneous and nonsimultaneous inference techniques are presented with an example of the latter's use. This approach is advocated for situations where it is suspected that dependent measures are a function of some initial aptitude…

Rationale and procedures for conducting process analysis in evaluation research are discussed. Two different procedures for estimating mediation are discussed, as well as procedures for examining whether a treatment exerts its effects, in part, by altering mediating process that produces outcome. Benefits of process analysis in evaluation research…
