Personally familiar proper names are relatively successfully processed in the human right hemisphere; or, the missing link

Responding to our abstract in Brain and Language (Ohnesorge & Van Lancker, 1999), which proposed that famous proper nouns are successfully processed in both cerebral hemispheres, Schweinberger, Landgrebe, Mohr, and Kaufmann (2001) claimed that the "link" between personal names and the right hemisphere is "illusory." Ohnesorge and Van Lancker (2001) further described six experimental studies in which LVF/RH recognition of famous proper nouns was influenced by task conditions and stimulus familiarity. Here presenting two more experiments performed to explore the refutation presented by Schweinberger et al., this article confirms an ability of the right hemisphere to recognize famous proper nouns and explains why appropriate stimulus development and task conditions are essential in furthering our understanding of the role of the right hemisphere in processing personal relevance.     

Effect of speech task on intelligibility in dysarthria: a case study of Parkinson's disease

This study assessed intelligibility in a dysarthric patient with Parkinson's disease (PD) across five speech production tasks: spontaneous speech, repetition, reading, repeated singing, and spontaneous singing, using the same phrases for all but spontaneous singing. The results show that this speaker was significantly less intelligible when speaking spontaneously than in the other tasks. Acoustic analysis suggested that relative intensity and word duration were not independently linked to intelligibility, but dysfluencies (from perceptual analysis) and articulatory/resonance patterns (from acoustic records) were related to intelligibility in predictable ways. These data indicate that speech production task may be an important variable to consider during the evaluation of dysarthria. As speech production efficiency was found to vary with task in a patient with Parkinson's disease, these results can be related to recent models of basal ganglia function in motor performance.     

A field study of two measures of work motivation for predicting leader's transformational behaviors

Relationships between motivation and transformational leadership were examined in this study. 56 leaders and 234 followers from a variety of organizations were sampled. Leaders were administered the Motivation Sources Inventory and the Job Choice Decision-making Exercise, while followers reported leaders' behaviors using the Multifactor Leadership Questionnaire (MLQ-rater version). Scores on the Motivation Sources Inventory subscales subsequently correlated with the Multifactor Leadership Questionnaire subscales of inspirational motivation, idealized influence (behavior), and individualized consideration (range, r = .13 to .23). There were no significant correlations among any of the Job Choice Decision-making Exercise subscales with any of the variables measured.     

Partner Violence, Social Support, and Distress Among Inner-City African American Women

This study examined the role of social support in the partner violence–psychological distress relation in a sample of African American women seeking medical care at a large, urban hospital (n = 138). Results from bivariate correlational analyses revealed that partner violence was related to lower perceived social support and greater psychological distress, and lower social support was related to more distress. Furthermore, findings based on path analysis indicated that low levels of social support helped account for battered women's increased distress. Findings point to the need for service providers to screen for partner violence in nontraditional sites, such as hospital emergency rooms, and to address the role of social support resources in preventive interventions with African American battered women.     

The name game: using retrieval practice to improve the learning of names

In medium-sized groups such as classes, it is often desirable that the members become acquainted with one another. Toward this end, various methods of introducing group members are often used, with only anecdotal evidence for their effectiveness. The name game is a method for introducing group members that is based on the principles of retrieval practice. The authors compared 2 versions of the name game with a widely used introductory method--pairwise introductions--and found that the name game participants were much better at remembering one another's name after 30 min, 2 weeks, and 11 months. A second experiment tested the contribution of retrieval practice by comparing 2 versions of the name game with a procedure that was matched for number of repetitions and time spent on the task. Again, the name games were superior.     

Even zombies Can be Surprised: A Reply to Graham And Horgan

In their paper “Mary, Mary, Quite Contrary” (2000), George Graham and Terence Horgan argue, contrary to a widespread view, that the so- called Knowledge Argument may after all pose a problem for certain materialist accounts of perceptual experience. I propose a reply to Graham and Horgan on the materialist’s behalf, making use of a distinction between knowing what it’s like to see something F and knowing how F things look.     

Perspectives and research on the positive and negative implications of having multiple racial identities

Much attention has been directed toward understanding the impact having a multiracial background has on psychological well-being and adjustment. Past psychological research has focused on the challenges multiracial individuals confront in defining a racial identity. The implication is that these challenges lead to outcomes that are psychologically detrimental. However, evidence to support this assertion is mixed. The authors review qualitative and quantitative empirical research examining multiracial individuals' identity development, depression, problem behaviors, peer relationships, school performance, and self-esteem, finding support for detrimental outcomes only in studies sampling clinical populations. Studies on nonclinical samples find that multiracial individuals tend to be just as well-adjusted as their monoracial peers on most psychological outcomes. Earlier assertions of maladjustment may have been due to reliance on qualitative research that sampled clinical populations. Other implications and future research are discussed.     

Paralinguistic processing in children with callosal agenesis: emergence of neurolinguistic deficits

Recent research revealed impaired processing of both nonliteral meaning and affective prosody in adults with agenesis of the corpus callosum (ACC) and normal intelligence. Since normal children have incomplete myelination of the corpus callosum, it was hypothesized that paralanguage deficits in children with ACC would be less apparent relative to their peers. The Familiar and Novel Language Comprehension Test (FANL-C) and Prosody Test were given to 18 children with ACC and normal intelligence and 17 controls matched for age (7-13 years), education, and IQ (83-122). When controlling for age, children with ACC were significantly poorer in comprehension of the precise meaning of both literal and nonliteral items on the FANL-C. Adults with ACC had previously been shown to have difficulty only on nonliteral items. The effect size for nonliteral comprehension in children with ACC was smaller than that seen in adults. There was only a trend for the child ACC group to perform worse on the recognition of affective prosody. Thus, while deficits in paralinguistic processing were apparent, children with ACC were not as clearly different from age peers as adults, and were equally deficient at comprehending literal and nonliteral expressions. The differences in results between adults and children with ACC are thought to reflect incomplete callosal development in normal children, and the importance of the corpus callosum in the early stages of the development of the ability to process literal language.
