Two well-known theorems from geometry are shown to be essentially the same using the principle of duality of lines and points. (MP)

Children and adults were trained and tested on formation of novel simple discriminations and conditional stimulus relations. Subjects who formed these sets were trained and tested on formation of stimulus equivalence classes. A modest majority of children matched directly paired stimuli; a few matched indirectly paired stimuli. All normal adults…

Used point-light displays (lights corresponding to the joints of the human body) to examine 3-year-olds' understanding of verbs. Found that children could extend familiar motion verbs (walking, dancing) to videotaped point-light actions shown in an intermodal preferential looking paradigm. Children watched the action matching the requested verb…

Autistic leading in four autistic children, aged three-five, was treated by strengthening pointing as an alternative form of request. Following intervention, pointing gradually replaced leading, and stimulus generalization was observed. Results indicate that functional equivalence and response efficiency can be procedurally combined to…

A reminding-based generalization view of category learning was studied in 4 experiments involving a total of 247 college students. Experiments demonstrated that categorization by reminding can affect what is learned about the category and later categorization performance. Implications of the results for category learning are discussed. (SLD)

Use of internal correlation for statistical analysis--as proposed by G. W. Joe and J. L. Mendoza (1989)--is discussed. Use of the bootstrap technique to deal with the distributional problem is questioned. Joe and Mendoza attempt the interpretation of the two linear composites that produce the largest internal correlation. (TJH)

The use of internal correlation for statistical analysis, as proposed by G. W. Joe and J. L. Mendoza (1989), is discussed. The suggestion of using bootstrapping is received well. Applications to collinearity are suggested. (TJH)

Examination of the effectiveness of a behavioral parent training package with three mothers of autistic children found that, although all parents increased their correct use of behavior modification skills following the introduction of intervention in two home settings, only one parent generalized these skills to a third home setting. (Author/DB)

Interview questions most frequently used and corresponding beneficial responses were derived from an empirical analysis of the "hiring community" and were used in developing a job interview skills training package for adults with developmental disabilities. Training resulted in improved responding by all subjects. Improved quality in responding to…

An assessment of identity matching to sample with 2-dimensional forms was conducted with 44 subjects with moderate and severe intellectual disabilities. Overall, generalized identity matching was demonstrated in 34 of 44 subjects, including 7 of 16 individuals with mental age scores below 3.0 years. (Author/DB)

In a peer interaction task involving controversial topics, 30 undergraduate psychology students identified strengths and weaknesses of various items of evidence. Participants could make some appropriate criticisms of evidence and were most positive about research-based evidence. However, generalizations were most frequently used to bolster…

Four experiments investigated 3-year-olds' understanding of the differential importance of shape for categorizing solid objects. Found that they categorized rigid and deformable objects differently in a non-naming task and knew that material was important for deformable items and shape for rigid items. In two naming tasks, they generalized names…

Examines mnemonic transfer in the form of knowledge generalization in the context of an artwork-learning task. Results reveal that mnemonic instruction produced memory benefits on a direct test, and that on a transfer task, mnemonic students who were directed to focus on the general style of the artist outperformed students who focused on details…

Examined influence of object labels and shape similarity on 16- to 21-month-olds' inferences. Found that infants generalized non-obvious property of unlabeled objects to test objects with highly similar shapes. For objects labeled with novel nouns, infants relied on shape similarity and shared labels to generalize properties. For objects labeled…

Two experiments tested a model of young children's induction that specified contributions of linguistic labels and perceptual similarity to children's induction. Results support model predictions and point to a developmental shift, from treating linguistic labels as an attribute contributing to similarity to treating them as markers of a common…
