Investigation of grammaticality judgments and decision times for 21 children in 2 age groups (ages 6-7 and ages 8-9) found good sensitivity to grammatical errors, with errors in word order more readily detected than errors of morphological selection. Older children processed errors somewhat more quickly. (Author/DB)

Discussion of document retrieval systems and measuring system performance focuses on the upper bounds, or maximum performance, that can be obtained with a system. Topics addressed include bounds for retrieval performance; average search length; average precision; incomplete searches; an asymmetric measure of retrieval performance; and measuring…

Relationships between multiple-choice test answer changing and testwiseness skills, and between these two variables and examination performance were studied with 150 college business students. Answer-changing behavior was related to multiple-choice test performance but not to testwiseness or performance on the nonmultiple choice portion.…

A study involving 553 college students, 27% of whom reported a history of child abuse, investigated whether family of origin dysfunction was associated with poorer childhood memory. Weak associations were found between family of origin dysfunction and poorer general quality of childhood memory. (Author/CR)

A model of the intrapersonal processes impacting computer-related performance was tested using data from 75 manufacturing employees in a computer training course. Gender, computer experience, and attributional style were predictive of computer attitudes, which were in turn related to computer efficacy, task-specific performance expectations, and…

Examines attitudes of 1,150 teachers from Charlotte-Mecklinberg (North Carolina) and 1,748 Kentucky teachers working under school-based performance award programs with monetary bonuses if their schools met or exceeded student achievement goals. Findings suggest that the motivational potential of the incentives can be offset by undesirable program…

Four studies were conducted to assess gender differences in the effects of extrinsic motivation on creativity. Results indicate expectations of evaluation and work for reward lowered the creativity of middle school girls, but not that of boys. Expecting ungraded feedback reduced the negative impact of expecting evaluation and the gender…

A study of 402 gifted Australian students grouped in selective high schools, 76 gifted students grouped in accelerated cohorts, and a mixed ability group of 62 students found intrinsic motivation was positively correlated with quality of school life variables and negatively associated with aspects of tedium. (CR)

Compared the mismatch-negativity (MMN) component of auditory event-related brain potentials to explore the relationship between phonological short-term memory and auditory-sensory processing in 7- to 9-year olds scoring the highest and lowest on a pseudoword repetition test. Found that high and low repeaters differed in MMN amplitude to speech…

Examined abilities of 3- to 16-year olds and adults to resist interference during the processing of two auditory dimensions of speech--the speaker's gender and spatial location. Found that the degree of interference from irrelevant variability in either dimension did not vary with age. In the presence of conflicting task-irrelevant information,…

Discusses the variety of performance measures available for information retrieval systems, search engines, and network filtering agents. Considers how measures of performance at a point in a search can be formally compared, develops criteria related to document orderings, and discusses equivalent ordering and precision and recall. (Author/LRW)

A study used the Assessment of Basic Learning Abilities to assess the abilities of three adults with mental retardation in order to reduce aberrant behavior. There was a higher frequency of aberrant responses during training sessions with training tasks above or below a participant's assessment level on the test. (Contains references.) (CR)

Examined preschoolers' ability to map novel adjectives to object properties in two experiments. Found that 4-year-olds could extend novel adjectives from target to matching test object whether objects were drawn from same, or different, basic level categories. If 3-year-olds' first extended a novel adjective to objects in the same basic level…

Three experiments investigated use of visual input and body movement input arising from movement through the world on spatial orientation. Experiments involved infants searching for a toy hidden in one of two containers. Findings indicated that search was best after infant movement in a lit environment prior to searching; all other conditions led…

Compared performance of children with autism, with learning disabilities, and normally developing 4-year-olds on reasoning problems with and without instruction to use imagery. Found that instruction to use imagery led to persistent logical performance. Children with autism displayed a distinctive response pattern, performing around chance levels,…
