Objective/Method: The Conner's Continuous Performance Test (CPT) was administered to four groups of adult college students who self-referred for comprehensive psychoeducational evaluation and received either no diagnosis (n = 30) or a diagnosis of ADHD (n = 26), a psychiatric disorder (n = 17), or various cognitive deficits (n = 22). Results: The…

This study examined irrelevant/incorrect answers produced by children with Asperger syndrome or high-functioning autism (7-9-year-olds and 10-12-year-olds) and normally developing children (7-9-year-olds). The errors produced were divided into three types: in Type 1, the child answered the original question incorrectly, in Type 2, the child gave a…

This study systematically investigates the English writing research in Taiwan, over the span of time from 1989 to 2008, a 19-year time period. Data collection consisted of five major sources. Guided by Juzwik et al's (2006) study, the data were analyzed based on the general problems under investigated, the age groups being researched, the…

Young Filipino children are expected to solve mathematical word problems in English, which is not their mother tongue. Because of this, it is often assumed that Filipino children have difficulties in solving problems because they cannot read or comprehend what they have read. This study tested this assumption by determining whether presenting word…

A geographer and a developmental psychologist collaborated on an investigation of the development of children's ability to comprehend, produce, and use graphic representations of space. Such representations are called "geo-graphics" in this paper. The researchers held that children's mastery of maps is dependent on their developing…

Algebra word problems were analyzed in terms of the information integration tasks that are required to solve the problems. These tasks were classified into three levels: value assignment, value derivation, and equation construction. Novices (35 first year algebra students) and experts (13 analytic geometry students) were compared on the proportion…

Isolates and analyzes the errors in the English speech of a Punjabi-speaking Indian. (CK)

The study investigated whether the pre-arrangement of math facts in spaced repetitions redundancy would increase the acquisition rate of a second grader with poor mathematics achievement. Baseline data were provided by observation of in-class math performance of addition sums zero through 18. In the experimental phase, worksheet problems were…

This paper is concerned with the role of meaning and understanding in the acquisition of computational skill in subtraction. Evidence on the syntactic nature of subtraction errors is reviewed, with common "bugs" described. Then, data collected from interviews with four children are summarized in terms of their semantics of concrete…

Assessment data and other research findings on fractions are briefly reviewed. These indicate that students are able to add and subtract fractions but have substantial difficulty finding and using common denominators. Selected results for nine-year-olds from the first and second national assessments of mathematics are used to portray what students…

We tested human performance on the Euclidean Traveling Salesman Problem using problems with 6-50 cities. Results confirmed our earlier findings that: (a) the time of solving a problem is proportional to the number of cities, and (b) the solution error grows very slowly with the number of cities. We formulated a new version of a pyramid model. The…

Spoonerisms can be elicited by having the subject articulate a target preceded by bias items. Any systematic difference in rate of errors between similar targets must result from processes after recoding of target into its slip. Editing processes make lexical outcomes more frequent than nonsense outcomes. (CHK)

The National Longitudinal Study of the High School Class of 1972 (NLS) employs a combination of mail, telephone, and personal interview data-gathering techniques. The NLS quality control process begins with editing each returned questionnaire to determine if certain key items are answered and if responses are consistent. If the respondent failed…

A research project is discussed involving the collection of production data from writing samples of 375 adult learners of English divided equally among five language backgrounds: Arabic, Chinese, Japanese, Persian, and Spanish. Information is presented about three constructions: (1) subject relative clause, (2) infinitival complement on verb, and…

During the 1975-76 academic year student response data were saved for a group of 17 freshman music majors as they worked through 15 units of harmonic dictation exercises delivered on the University of Delaware's Graded Units for Interactive Dictation Operation (GUIDO) system. Analysis of the student data base led to the identification of seven…
