Prismatic displacement and the remembered location of targets

Following adaptation, only the trained limb misreaches to the remembered location of targets. This suggests a change in the feit position of the trained limb, but conflicts with recent reports, and with the hypothesis that when a limb changes, the remembered location of targets encountered only by that limb undergo some change too. It suggests that information is stored independently of the mode of acquisition.     

Sind die klassische Mechanik und die spezielle Relativitätstheorie kommensurabel?

In its first part, this paper shows why a recently made attempt to reduce the special theory of relativity to Newtonian kinematics is bound to fail. In the second part, we propose a differentiated notion of incommensurability which enables us to amend the contention that the special theory of relatively and Newtonian kinematics are incommensurable.     

ACADEMIC EFFECTS OF PROVIDING PEER SUPPORT IN GENERAL EDUCATION CLASSROOMS ON STUDENTS WITHOUT DISABILITIES

We studied the academic effects on peers without disabilities of serving as peer supports for students with disabilities in general education classrooms. Three peers were studied using a range of indicators, including academic engagement, coursework performance, and social validity assessments. Peers assisting a student with disabilities via curricular adaptation, assignment completion, and social facilitation constituted the multicomponent independent variable. We used withdrawal or multiple baseline designs to demonstrate positive benefits for peers for all measures used. In addition, follow-up data for 2 peers indicated that the positive changes associated with serving as a peer support were maintained for up to 2 months. Our results are discussed in relation to the possible academic and social effects of providing peer supports in general education classrooms for students with and without disabilities.     

Nodality effects during equivalence class formation: An extension to sight-word reading and concept development

Three students with moderate disabilities were taught to read and match-to-sample sight words comprising stimulus sets based upon the four food groups. We taught students conditional discriminations within four four-member sets using a single-sample/four-comparison procedure. Students were taught A-B, B-C, and C-D conditional discriminations for each of the four potential stimulus classes. Subsequent probes tested for relations based upon symmetry and one-node and two-node transitivity. The performances for all students indicated that symmetric relations emerged before one-node transitive relations, and that one-node transitive relations emerged before two-node transitive relations. These results are consistent with a pattern of responding, referred to as a "nodality effect," in which relations with fewer nodes are demonstrated prior to the demonstration of relations with a greater number of nodes. These results extend this area of research to sight-word reading for students with moderate disabilities.     

Comparing interspersed requests and social comments as antecedents for increasing student compliance

Two students were alternately presented with interspersed high-compliance requests and social comments as antecedents to low-compliance requests. An initial comparison demonstrated similar positive effects on compliance for interspersed requests and social comments. A second analysis indicated that the effectiveness of social comments for increasing compliance was related to the time interval between social comments and low-compliance requests.
