Purpose: To quantitatively assess a Senge learning organization (LO) intervention to determine if it would result in improved employee satisfaction. Design/methodology/approach: A Senge LO intervention in Division 123 of Company ABC was undertaken in 2000. Three employee surveys using likert-scale questions over five years and correlation analysis…

The present study examined the neural correlates of speech and hand gesture comprehension in a naturalistic context. Fifteen participants watched audiovisual segments of speech and gesture while event-related potentials (ERPs) were recorded to the speech. Gesture influenced the ERPs to the speech. Specifically, there was a right-lateralized N400…

Background: Brain morphology and physiological measures in schizophrenia have yielded inconsistent results. This may be due in part to difficulties in ascertaining precisely to what degree each measure deviates from its genetically and environmentally determined potential level. We attempted to surmount this problem in a paradigm involving…

The present work aims at demonstrating that visual training associated with the act of reading modifies the way we perceive printed words. As reading does not train all parts of the retina in the same way but favors regions on the side in the direction of scanning, visual word recognition should be better at retinal locations that are frequently…

The tetrachoric correlation describes the linear relation between two continuous variables that have each been measured on a dichotomous scale. The treatment of the point estimate, standard error, interval estimate, and sample size requirement for the tetrachoric correlation is cursory and incomplete in modern psychometric and behavioral…

This meta-analysis reviewed the literature on socioeconomic status (SES) and academic achievement in journal articles published between 1990 and 2000. The sample included 101,157 students, 6,871 schools, and 128 school districts gathered from 74 independent samples. The results showed a medium to strong SES-achievement relation. This relation,…

In a previous study (Dronkers, 1996), stroke patients identified as having apraxia of speech (AOS), an articulatory disorder, were found to have damage to the left superior precentral gyrus of the insula (SPGI). The present study sought (1) to characterize the performance of patients with AOS on a classic motor speech evaluation, and (2) to…

This study explored asymmetries for movement, expression and perception of visual speech. Sixteen dextral models were videoed as they articulated: "bat," "cat," "fat," and "sat." Measurements revealed that the right side of the mouth was opened wider and for a longer period than the left. The asymmetry was accentuated at the beginning and ends of…

Guided by the Model of Domain Learning (MDL), the study was designed to explore the extent of interrelations among prior knowledge, learning strategies, interests, physical engagement, and learning outcomes in a sixth-grade (N = 91) volleyball unit. Pearson product-moment correlations and a path analysis were conducted for the research purpose.…

An unresolved issue in student evaluations of teaching effectiveness (SETE) literature is what type of overall evaluation of teaching effectiveness should be used in personnel decisions. The objective of this study is to compare the merits of: (a) an overall evaluation made by students, (b) a weighted average overall evaluation with the weights…

There are several legitimate ways of conceptualizing and studying wisdom. One is largely informed by Western philosophy and treats wisdom as an analytic theory of expert knowledge, judgment, and advice about difficult and uncertain matters of life. Another is more consistent with Asian philosophical nonsecularized traditions and treats wisdom as…

The authors examined state dependency on depression, trait stability, and state-trait characteristics of perfectionism in a short-term longitudinal study of university students. Relative stability of perfectionism was assessed with test-retest correlations across 3 time points, and results showed higher rank order and relative stability for…

This study investigated whether participation in the Chicago Child-Parent Center (CPC) Preschool Program associated with higher educational attainment (high school completion, highest grade completed, and college attendance) at age 22. The study sample included 1,334 youth (869 in the preschool group and 465 in the comparison group) from the…

This research project is an exploratory study that aims to describe and examine the state and nature of the quality of life of street children accommodated at three shelters. A non-probability sample of 48 street children at three shelters was purposively selected. An interview schedule was constructed and administered to gather data. The…

This paper reports a study designed to examine the neuronal correlates for comprehending the signs of American Sign Language representing numerals in deaf signers who acquired Japanese Sign Language as their first language. The participants were scanned by functional magnetic resonance imaging (fMRI) twice on the day of the experiment. The results…
