Improving Migrant Students' Spelling of English and Spanish Words with Error Correction

We examined the effects of error correction on spelling accuracy of culturally and linguistically diverse students enrolled in summer Migrant Education. In an error correction strategy, students spelled a word, viewed a correct model, and corrected specific errors. In a traditional strategy, students wrote words three times each while viewing a correct model. Words were presented in Spanish or English. Results showed that students with and without learning disabilities, whose primary language was English, correctly spelled more English words in the error correction condition than the traditional. Students whose primary language was Spanish correctly spelled Spanish words equally well in both conditions, possibly because of the phonetic nature of the Spanish language.     

Transitive inference in pigeons: Control for differential value transfer

Transitive inference (TI) effects have been demonstrated in several nonhuman species using a nonverbal version of the task in which A is better than B is represented in a simple simultaneous discrimination, A+B?. Following five-term training (e.g., A+B?, B+C?, C+D?, D+E?), the choice of B over D on test trials is taken as evidence of TI. Recently, differential value transfer from the S+ to the S? in a simultaneous discrimination has been proposed as a noncognitive basis for these effects. Two experiments were conducted to control for differential value transfer. The results suggest that differential value transfer is not the only basis for nonhuman TI performance. An alternative account based on spatial mapping is discussed.     

Division of attention: Age differences on a visually presented memory task

Young and old adults were compared in their efficiency of remembering concurrently presented series of letters and digits in three separate experiments. Instructions and payoffs to vary attentional emphasis across the two types of material in different conditions allowed the examination of attention-operating characteristics in the two age groups. Strategy-independent measures derived from these attention-operating characteristics revealed that older adults exhibited greater performance deficits than young adults when dividing their attention between the two tasks, even though dual-task difficulty was individually adjusted for each subject. It was concluded that either the total amount of attention available for distribution or the efficiency of its allocation decreased with age even though the ability to vary one’s attention between concurrent tasks in response to instructions and payoffs remained intact.     

TOO MUCH REINFORCEMENT,TOO LITTLE BEHAVIOR: ASSESSING TASK INTERSPERSAL PROCEDURES IN CONJUNCTION WITH DIFFERENT REINFORCEMENT SCHEDULES WITH AUTISTIC CHILDREN

Task interspersal procedures have been quite effective in increasing autistic children's motivation to learn. These procedures have typically demonstrated that the inclusion of reinforced maintenance tasks (previously learned tasks) increases responding to new acquisition tasks because more reinforcers, in general, are available. However, studies have not specifically addressed the effects of various schedules of reinforcement, used in conjunction with task interspersal procedures, upon response acquisition. In the present study, a multiple baseline design across subjects was used to assess different reinforcement schedules. Five autistic children participated in learning sessions, during which trials of an acquisition task were interspersed with trials of three maintenance tasks. Correct responses to acquisition tasks were continuously reinforced throughout all conditions, while the reinforcement schedule for competent performance of maintenance tasks differed systematically. Results indicated that all children learned the new tasks when food reinforcers were presented only for acquisition tasks. Results are discussed in terms of behavioral contrast and improving the effectiveness of motivation-enhancing procedures for autistic children.     

Student characteristics and motivational and process factors in relation to styles of career development

In this study student background characteristics and certain personological characteristics, including motivations for schooling and types of learning strategies employed, are investigated in relation to affective and cognitive aspects of adolescent career development. A Career Development Inventory, Learning Process Questionnaire, Word Knowledge test and General Information Questionnaire (addressing demographic and career decision-making topics) were administered to national random samples of 14-year-old and grade 11 students. Canonical correlation analyses distinguished at least three styles of career development (possibly four), and associations with student characteristics suggested the motives and strategies that might plausibly enter into the various modes.     

Adolescents' perceptions of the causes and consequences of success in sex-linked occupations

Junior and senior high school students rated the extent to which occupational success is attributable to internal versus external factors and the extent to which it results in negative versus positive outcomes; 144 seventh through twelfth graders responded to one of six success cues in which either a male or female character was depicted achieving success as a doctor, nurse, or department head. Junior high girls assigned a more positive valence to success than junior high boys (p<.001), with no sex differences among the senior high subjects. Girls of both age groups were more likely to rate success as difficult to achieve (p<.01) and requiring more effort (p<.05), while boys were more likely to indicate that success was a function of luck (p<.01). Socialization influences which may have mediated the age and sex differences are discussed.     

Rationale and considerations for proposed near-death research in the hospital setting

Further research into the question of veridical perception during the naturalistic near-death out-of-body experience (nND OBE), that phase of the near-death experience in which the experiencer seems to be perceiving a normal earthly realm, would be of value to NDErs, their caregivers, and humanity in general. I propose a research procedure that targets visual perception during nND OBEs that occur in the hospital setting. I discuss unresolved issues in the design and implementation of such a procedure, and identify areas for further research.
