Development of the attitude toward science in school assessment and its use to investigate the relationship between science achievement and attitude toward science in school

There is much interest in science courses in high school and student attitudes toward those courses. A valid and reliable instrument that measures such attitudes is not available. This study first developed and validated the Attitude toward Science in School Assessment (ATSSA). The instrument was used to evaluate the relationship between such attitude and achievement in science. A low correlation was found between attitude and various achievement tests. A moderate correlation was found between attitude and achievement that included an evaluation of the quality of work, as in a course grade.     

Incidence and situational factors surrounding sexual assault against delinquent youths

This study reports the results of extensive interviews with an intact sample of moderately delinquent adolescents concerning their sexual assault histories. Findings indicate a surprisingly high incidence of victimization among the females interviewed which, the authors suggest, may characterize the larger population of delinquent females. The behavioral-situational contexts of reported victimization experiences are examined for salient commonalities and the following composite rape scenerio can be cast from the data: An unsupervised, 14-year-old female, who has been consuming alcohol or marijuana, is sexually assaulted, following threat and/or force, to the point of penile-vaginal penetration, by an older male friend or acquaintance (who has also consumed alcohol or marijuana) in his home or vehicle or other place where she is inherently unprotected. Some comments are offered concerning the requirements of an effective technology of child rape prevention.     

Generalization of serial learning in the pigeon

Sequence learning in pigeons was studied in asimultaneous chaining paradigm: all stimuli and the opportunity to respond to each stimulus were available simultaneously. In contrast to the traditionalsuccessive chaining paradigm, a simultaneous chaining paradigm provides no differential feedback following each response (except the last). Subjects were first trained to perform on sequences of two (AB), then three (ABC), and then four colors (ABCD). Performance greatly exceeded that predicted by models of random choice. Generalization to novel arrays of three and four colors was complete. After training with a four-color sequence, the subjects were tested with subsequences consisting of all possible combinations of two and three of the four training colors (e.g., BD, AD, BC, ACD, BCD, etc.). The successful completion of these subsequences showed that the organization of the original sequence did not entail overt pecks to successive elements of that sequence. That subjects can respond accurately on nonadjacent subsets is not readily explained by a chaining theory, or by any theory that assumes that responding to element n provides a cue for responding to element n+1.
