Factorial invariance of the theory of planned behavior applied to physical activity across gender,age, and ethnic groups

Objectives:The present study assessed the generalizability of the Theory of Planned Behavior (TPB) applied to physical activity and to examine if the TPB operates equivalently across gender, age, and ethnic sub-groups.Design/Methods:Measurement equivalence was evaluated for gender (male/female), age (19–34/35–54/55+) and ethnicity (Japanese/Hawaiian or part Hawaiian/Filipino/White) in a random sample (n = 3533) using Multisample Structural Equation Modeling.Results:Measurement equivalence was found for all variables and for their intercorrelations. Of the 100 possible TPB variable relationships between groups, only 6 were significant. The differences were found in explained variances of physical activity.Conclusions:The findings indicate that TPB measures apply over a range of population sub-groups, and should be considered comprehensively when designing interventions.     

Effects of working memory capacity on mental set due to domain knowledge

The present set of studies examines how working memory capacity (WMC) relates to performance on a Remote Associates Task (RAT), originally designed by Mednick as a quantifiable creative problem solving assessment. The source of fixation was manipulated across two sets of RAT items. One set was neutral with no specific fixation embedded in them, while the second set was baseball-misleading, designed so that prior knowledge of baseball would lead to an incorrect solution attempt. WMC scores were positively related to performance on RAT items in all conditions, except one. High baseball knowledge participants' WMC scores did not relate to performance on the baseball-misleading RAT. While in general WMC may lead to better RAT performance, these results suggest that when there is a candidate solution strongly activated by prior knowledge, WMC may actually lead to too much focus on the incorrect solution and exacerbate mental sets.     

Comparison of Single Unit Responses to Tone, Light, and Compound Conditioned Stimuli during Rabbit Classical Eyeblink Conditioning

Unit recordings and lesion studies have implicated the cerebellum as an essential site for the acquisition and maintenance of the conditioned eyeblink response. The current study looked at the neural characteristics of conditioned stimulus (CS) processing in the interpositus nucleus of the cerebellum after training New Zealand white rabbits (Oryctolagus cuniculus) in one of two conditioning paradigms: (a) compound conditioning (CMP), a compound CS consisting of light and tone paired with an air puff unconditioned stimulus (US); or (b) stimulus compounding (ALT), alternating blocks of tone CS and light CS trials paired with the air puff US. Single unit responses were recorded during five sessions after the animals had reached an asymptotic level of responding. Animals were tested for behavioral and neural responses to CS alone trials that included tone alone, light alone, and compound tone-light trials. For the CMP group, the compound CS elicited 80 to 90% conditioned eyeblink responses (CRs), whereas the individual tone and light CSs elicited only 40 to 50% CRs. For the ALT group, all three CSs (tone, light, and compound) elicited very high levels of responding of at least 80% CRs. For the CMP group, there were roughly equal numbers of cells responding to all of the CSs. This includes cells that responded exclusively to one, and only one, of the three stimuli and also those cells that responded to combinations of two or more. Cells from the ALT group were far more likely to respond exclusively to only one of the CSs. Both the behavioral and physiological results suggest that the compound tone-light stimulus was processed as a distinct stimulus, separate from the component tone and light. These results are discussed in the context of multisensory processing.     

Personality maturity and Teresa's interior castle

The ego development stage model theory of Jane Loevinger is compared to the understanding of St. Teresa of Avila regarding development in spiritual life. The paper first presents Loevinger's theory, then goes through the mansions Teresa described in the interior castle of the soul, comparing each mansion with Loevinger's understanding. The paper concludes that a very similar line of development is traced in both understandings.This paper is a revision of a paper first presented to Division 36, Psychologists Interested in Religious Issues, at the annual meeting of The American Psychological Association.     

Facilitative school leadership and teacher empowerment: Teacher's perspectives

In recent years, facilitative forms of leadership and teacher empowerment for the democratic restructuring of schools have been emphasized. However, no published studies seem to have examined teachers' perspectives of both facilitative school leadership and empowerment. This article describes the everyday strategies and personal characteristics of exemplary principals practicing facilitative leadership in shared-governance schools and how these principals influenced teacher empowerment. The date were drawn from a qualitative study of teachers in 11 schools in Georgia. An openended questionnaire was designed to provide teachers the opportunity to identify and describe in detail the characteristics of principals that enhanced their sense of empowerment and what being empowered means to teachers. Inductive analyses of the data generated seven major strategies, one set of personal characteristics identified with facilitative leadership, and two major dimensions of teacher empowerment: affective and professional. This article emphasizes the meanings teachers identified with empowerment.     

Augmented Feedback Presented in a Virtual Environment Accelerates Learning of a Difficult Motor Task

One can use a number of techniques (e.g., from videotaping to computer enhancement of the environment) to augment the feedback that a subject usually receives during training on a motor task. Although some forms of augmented feedback have been shown to enhance performance on isolated isometric tasks during training, when the feedback has been removed subjects have sometimes not been able to perform as well in the "real-world" task as controls. Indeed, for realistic, nonisometric motor tasks, improved skill acquisition because of augmented feedback has not been demonstrated. In the present experiments, subjects (Experiment 1, N = 42; Experiment 2, N = 21) performed with a system that was designed for teaching a difficult multijoint movement in a table tennis environment. The system was a fairly realistic computer animation of the environment and included paddles for the teacher and subject, as well as a virtual ball. Each subject attempted to learn a difficult shot by matching the pattern of movements of the expert teacher. Augmented feedback focused the attention of the subject on a minimum set of movement details that were most relevant to the task; feedback was presented in a form that required the least perceptual processing. Effectiveness of training was determined by measuring their performance in the real task. Subjects who received the virtual environment training performed significantly better than subjects who received a comparable amount of real-task practice or coaching. Kinematic analysis indicated that practice with the expert's trajectory served as a basis for performance on the real-world task and that the movements executed after training were subject-specific modifications of the expert's trajectory. Practice with this trajectory alone was not sufficient for transfer to the real task, however: When a critical component of the virtual environment was removed, subjects showed no transfer to the real task.     

The impact of generic word choices: An empirical investigation of age- and sex-related differences

Previous studies of receivers' responses to generic words have found that adults generally develop masculine imagery for neutral words and that men do this more than women. The present investigation of school-aged children (n=471) found that they, like adults, develop sex-specific masculine imagery in response to apparently neutral messages. Early adolescents, however, reported significantly more inclusive imagery than 6–7-year-olds. Different pronoun conditions elicited different mental imagery for the receivers of the messages with he/she eliciting more of a balance between male and female images and they eliciting more inclusive imagery.This work was supported by a grant from the Indiana University—Purdue University at Fort Wayne Research and Instructional Development Support Program.
