Taking patterns for chunks: is there any evidence of chunk learning in continuous serial reaction-time tasks?

When exposed to a regular sequence, people learn to exploit its predictable structure. There have been two major ways of thinking about learning under these conditions: either as the acquisition of general statistical information about the transition probabilities displayed by the sequence or as a process of memorizing and using separate chunks that can later become progressively composed with extended practice. Even though chunk learning has been adopted by some theories of skill acquisition as their main building block, the evidence for chunk formation is scarce in some areas, and is especially so in the continuous serial reaction-time (SRT) task, which has become a major research tool in the study of implicit learning. This article presents a reappraisal, replication and extension of an experiment that stands so far as one of the few alleged demonstrations of chunk learning in the SRT task (Koch and Hoffmann, Psychological Res., 63:22–35, 2000). It shows that the effects which were taken as evidence for chunk learning can indeed be obtained before any systematic training and thus surely reflect a preexistent tendency rather than a learned outcome. Further analyses of the effects after extended practice confirm that this tendency remains essentially unchanged over continuous training unlike what could be expected from a chunk-based account of sequence learning.     

The relation between employee organizational and professional development activities

A model is presented showing hypothesized common and parallel antecedents of employee organizational development activity (ODA) versus professional development activity (PDA). A common antecedent is expected to affect both ODA and PDA, while a parallel antecedent is expected to affect its corresponding work referent. This model was tested using a sample of 197 medical technologists over a four year time period. Prior ODA and PDA were controlled for before testing hypotheses. Results showed that the common antecedent of learning motivation was a robust indicator of both ODA and PDA. Looking at parallel antecedents, job satisfaction and affective organizational commitment had a positive impact on ODA, while occupational satisfaction and affective occupational commitment had a positive impact on PDA. ODA had a negative impact on subsequent intent to leave organization, but PDA did not have a similar impact on intent to leave profession. Study limitations, issues around operationalizing ODA and PDA, and future research directions are discussed.     

E‐jing: Using Information Technology to Teach about Chinese Religions

Abstract. This article discusses ways in which modern online information technologies may be used to enhance students' understanding of Chinese religions and religious texts. This discussion is predicated upon a model of linguistic communication that places significant weight on the structures and “sedimented presuppositions” of language in determining the meanings of discourse. Assignments are presented that use online technologies to give even beginning students insight into the presuppositions of Chinese religious discourse, while also allowing them to explore, kinesthetically, one of Confucianism's central practices, the reading and writing of Chinese characters. Appendices providing additional materials related to the course are available online: http://www.wabashcenter.wabash.edu/journal/article2.aspx?id=14153 .     

Couples, Existential Psychotherapy, and Myocardial Infarction: A Ten Year Evaluation Study

Existential psychotherapy with couples after the occurrence of a myocardial infarction can be a useful, effective, and productive service approach in combination with medical services and cardiac rehabilitation services. In this article the existential treatment dynamics of holding, telling, mastering, and honoring with couples after a heart attack are described and illustrated. In addition, data from a 10-year before-after field evaluation study is reported, which supports the usefulness of the treatment approach.     

A cross‐cultural assessment of attitudes regarding perceived breaches of ethical conduct by both parties in the business‐consumer dyad

Recent initiatives in business curricula have included emphases on global business and ethics. Using 28 scenarios which reflect potential concerns regarding the conduct of either business or a consumer, this research combines these issues by comparing the ethical predisposition of business students in Australia with their Canadian counterparts. A sample of 264 students indicated that students in both countries generally hold high expectations for the behaviour of business and consumers. Both groups exhibited quite similar views in relation to the 28 consumer and business‐related scenarios. When comparing Canadian students to Australian students, four significant differences were documented in the 14 scenarios which address the behaviour of business entities. The assessment of attitudes regarding questionable consumer actions provided even more homogeneity as only one statistically significant difference was identified. The study concludes by documenting a series of attitudinal differences on the part of groups defined not by nationality, but rather on the basis of gender or age. These demographic differences were more pronounced than were the differences across the two countries. Copyright © 2003 Henry Stewart Publications.     

World View Concepts in Existential Family Therapy

Essence oriented and existence oriented approaches to family psychotherapy are very different treatment forms. This article compares and contrasts these two orientations in an effort to clarify the basic world view beliefs in existential psychotherapy with couples and families.     

Predicting athletic performance from cardiovascular indexes of challenge and threat

This study examined the relationship between pre-performance motivational states (challenge vs. threat) and subsequent performance in athletic competition. Prior to the season, college baseball and softball players imagined and gave a speech about a specific baseball/softball playing situation while cardiovascular indexes of challenge and threat were recorded. These physiological challenge/threat indexes significantly predicted athletic performance during the subsequent season, such that players who experienced challenge in the laboratory performed better relative to those who experienced threat. The implications for personnel selection and the biopsychosocial model of challenge and threat are discussed.     

No More Like Pallas Athena: Displacing Patrilineal Accounts of Modern Feminist Political Theory

The history of modern feminist political theories is often framed in terms of the already existing theories of a number of radical nineteenth‐century men philosophers such as James Mill, John Stuart Mill, Charles Fourier, Karl Marx, and Friedrich Engels. My argument takes issue with this way of framing feminist political theory by demonstrating that it rests on a derivation that remains squarely within the logic of malestream political theory. Each of these philosophers made use of a particular discursive trope that linked the idea of women's emancipation with the idea of social progress. I argue that this trope reproduced the masculinist signification and symbolism inherent in their particular political philosophies. I argue for a more positive, less masculinist, account of the history of feminist political thought.     

Psychological Acculturation of Ethnic Minorities Into White Anglo American Culture: Consequences and Predictors1

The United States is comprised of a patchwork of ethnic groups. To varying degrees, such groups have become acculturated into the White Anglo American culture. Our study is an attempt to examine the consequences and predictors of psychological acculturation. The data were taken from 320 students attending a large state university on the West Coast of the United States. Our results show that grade point average (GPA) and income earned were positively related to psychological acculturation. Religion, ethnicity, age of entry to the United States, enrollment in a graduate program, and self‐esteem affected psychological acculturation. The implications of the results are discussed.     

Association of Behavioral Self-Regulation with Concurrent Functional Capacity Among Stroke Rehabilitation Patients

The purpose of this study was to test the hypothesis that the Behavioral Dyscontrol Scale (BDS), a measure of the executive cognitive capacity to use an intention to guide purposeful, goal-directed activity would be strongly associated with concurrent functional status after controlling for age, sex, education, severity of pain, medical comorbidity, depression, and general mental status, in a sample of 246 elderly inpatients receiving rehabilitation services following hospitalization for stroke. Functional status was assessed by rehabilitation nurses' ratings of patients on 11 ADL items and on the Barthel Index. The BDS was the strongest predictor for 11 of the 12 dependent variables. Although it correlated significantly with all outcomes, the MMSE entered only one of the regression models. Of the other covariates, only age and severity of pain made an additional contribution to the prediction of functional ability for more than 1 dependent variable. Consistent with prior results in several other samples, the ability to use intentions to guide purposeful behavior appears to be an important contributor to everyday functioning among older adults.
