Second-order covariation is a form of mathematical reasoning that needs to be characterized both concerning students' cognitive processes and the design of tasks that promote it. This contribution aims to shed light on these two issues by comparing data related to the same learning experiment performed in two different learning environments:…

The present paper examines possible benefits of spatial audio guides on learning outcomes in the spatial learning setting of an experimental exhibition and attempts to differentiate between different mechanisms underlying such an effect. In Experiment 1, we examined whether the spatial contiguity principle may be such a mechanism. A spatial audio…

Objective: ADHD and autism are complex and frequently co-occurring neurodevelopmental conditions with shared etiological and pathophysiological elements. In this paper, we attempt to differentiate these conditions among the young people in terms of intrinsic patterns of brain connectivity revealed during resting state using machine learning…

Do children and adults use the same cues to judge whether someone is a reliable source of information? In 4 experiments, we investigated whether children (ages 5 and 6) and adults used information regarding accuracy, confidence, and calibration (i.e., how well an informant's confidence predicts the likelihood of being correct) to judge informants'…

Research Findings: The current study examined achievement motivation orientation in preschool-age children from low- and middle-income families. Participants were 126 children who were attending an urban Head Start site or a private preschool. Children's motivation orientation was assessed as being performance oriented or mastery oriented using a…

This study assessed the effectiveness of a three-step cognitive strategy (TIP) for calculating tip and total bill for young adults with intellectual disability. In the context of pre- and post-test nonequivalent-groups design, 10 students from a postsecondary education program for individuals with disabilities participated in the study. A teacher…

Determined effects of various methods and formats on subjects' (N=253) responses to a Piagetian reasoning problem requiring control of variables. Results indicate that format but not method of task administration influences subjects' performance and that the influence is similar for various combinations of methods and format. (Author/JN)

The relationship between speed of information processing (SIP) and psychometric intelligence was investigated by giving 60 college students (22 males and 38 females) 2 choice reaction time (RT) tests (modified Hick paradigm) and Raven's Advanced Progressive Matrices. Results support an association between intelligence and SIP. (SLD)

This report summarizes the work conducted for the Artificial Intelligence Measurement System (AIMS) Project which was undertaken as an exploration of methodology to consider how the effects of artificial intelligence systems could be compared to human performance. The research covered four areas of inquiry: (1) natural language processing and…

The verbal organizing abilities of the bilingual, multilingual, and monolingual, as measured by four subscales of the Goyer Organization of Ideas Test (GOIT), were investigated. A total of 163 subjects from 5 universities having high populations of multilingual students were administered the GOIT. Bilinguals were not as effective on the sequential…

Administered a complex reaction time task to 47 learning-disabled and 41 control children. The preparatory interval between a warning and act light was manipulated for length and regularity. Results indicated that the inability to sustain attention over time, rather than momentary inattentiveness, distinguished the two groups. (Author)

A correlational analysis was performed to examine the relationship between recognition and recall test formats. A total of 236 college students completed one of four 80-item general knowledge tests; the forms contained 20 items of each of four formats: (1) true; (2) false; (3) multiple-choice; and (4) free response. Ninety-three of the subjects…

This study investigates the validity of the Stanford Binet Intelligence Scale-Fourth Edition (S-B:4) for use with students with learning disabilities. It compares the performance of 18 elementary-age students on the S-B:4 and the Kaufman Assessment Battery for Children (K-ABC). The subjects were identified by their school as having learning…

A sample of 21 guidance counselors was administered the full battery of Johnson O'Connor Research Foundation aptitude tests to compare scores with the "general population" (norm group). The counselors had worked in public schools, private schools or as self-employed consultants for an average of 10 years. The average age was 42. The tests, which…

This study evaluated the diagnostic validity of a task measuring abstract categorization ability in learning disabled (LD) and non-LD children. Data showed that the component of abstract category knowledge that best disciminates LD children from non-LD, is the knowledge of how members of abstract categories differ from each other.
