Specialization in Psychology and Health Care Reform

This article begins by contextualizing specialization and board certification of psychologists, with attention paid to relevant definitions and expectations of other health care professionals. A brief history of specialization and board certification in professional psychology is offered. The benefits of board certification through the American Board of Professional Psychology are highlighted. Consideration is then given to the primary reasons for psychologists working in academic health sciences centers to specialize in the current health care climate and to obtain board certification as a mark of such specialization.     

Investigating Two Approaches to Fostering Children's Comprehension of Literature

This instructional study investigated the effects of two approaches to fostering elementary students' comprehension of literature. Participants were 54 third-grade students in 2 classrooms in a linguistic and culturally diverse, urban elementary school. Students read two folktales, receiving a Scaffolded Reading Experience (SRE) unit with one folktale and a unit we termed a Response-Oriented approach with the other folktale in a counterbalanced fashion. Classes were observed throughout both units and students completed multiple-choice and short-answer tests after reading each story and receiving the unit instruction. Teachers were interviewed after presenting both units. Results on the multiple-choice tests showed that students scored significantly higher when receiving the SRE units and that teachers preferred the SRE unit lessons. However, there were no differences between the two approaches on the short-answer tests, and teachers noted that some of the activities in the Response-Oriented units were very useful. Our conclusions are that both the Response-Oriented units and the SRE units provided strong scaffolding for students' reading, that the two approaches should be thought of as complementary rather than as competing, and that there is a place for both of them in classrooms that seek to build both comprehension and appreciation of literature.     

The Myth of Gender Cultures: Similarities Outweigh Differences in Men's and Women's Provision of and Responses to Supportive Communication

Michaud and Warner (1997) and Basow and Rubenfeld (2003) recently reported studies of gender differences in “troubles talk” that allegedly provide support for the different cultures thesis, that is, the notion that men and women communicate in such different ways that they should be regarded as members of different communication cultures or speech communities. In this article, we identify several limitations in these two studies that, collectively, have the effect of casting doubt on their conclusions. We then report three studies that show that men and women provide and respond to supportive messages (“troubles talk”) in ways that are much more similar than different. The current findings, in conjunction with other recent findings, suggest that the different cultures thesis is a myth that should be discarded.     

Hemispheric contributions to pragmatics

Twenty-seven patients with right-hemisphere damage (RBD) and thirty-one patients with left-hemisphere damage (LBD) received a new pragmatics battery in Hebrew consisting of two parts: (1) comprehension and production of basic speech acts (BSAs), including tests of assertions, questions, requests, and commands, and (2) comprehension of implicatures, including implicatures of quantity, quality, relevance, and manner. Each test had a verbal and a nonverbal version. Patients also received Hebrew versions of the Western Aphasia Battery and of the Right Hemisphere Communication Battery. Both LBD and RBD patients were impaired relative to controls but did not differ from each other in their overall scores on BSAs and on Implicatures when scores were corrected by aphasia and neglect indices. There was a systematic localization of BSAs in the left hemisphere (LH) but not in the right hemisphere (RH). There was poor localization of Implicatures in either hemisphere. In LBD patients, BSAs were associated with language functions measured with the WAB, suggesting the radical possibility that the classic localization of language functions in aphasia is influenced by the localization of the BSAs required by aphasia language tests. Both BSAs and implicatures show greater functional independence from other pragmatic, language and cognitive functions in the RBD than in the LBD patients. Thus, the LH is more likely to contain an unmodular domain-nonspecific set of central cognitive mechanisms for applying means-ends rationality principles to intentional activity.     

Pervasive influence of semantics in letter and category fluency: a multidimensional approach

We used multidimensional statistical procedures to study semantic and lexical processes underlying word retrieval in verbal-fluency performance. Forty healthy participants were given a two-choice letter task (i.e., generate items beginning with the letter 'A' or 'F', in any order) and a two-choice category task (i.e., generate animal or fruit names, in any order). Using correspondence analysis (CoA) and hierarchical clustering (HC), we found evidence of prominent semantic organization in both letter and category fluency. For example, a striking categorical segregation between animate and inanimate entities emerged during the letter task. Analysis of inter-item times revealed strong sequential priming effects in both tasks. Taken together, these results indicate that semantic facilitation is pervasive in word retrieval processes, even in the letter-fluency task, and therefore suggest that the traditional view of letter fluency as a purely phonemically based task should be revised. Finally, our findings may help explain patterns of verbal-fluency measures obtained in focal brain lesion patients.     

Refining CVLT-II recognition discriminability indices to enhance the characterization of recognition memory changes in healthy aging

The present study examined age-related differences on the four false-positive (FP) error subtypes found on the California Verbal Learning Test-Second Edition yes/no recognition memory trial and the influence of these subtypes on source and novel recognition discriminability (SoRD and NRD, respectively) index calculations. Healthy older (n = 55) adults generally made more FP errors than healthy young adults (n = 57). Accordingly, older adults performed worse than young adults on all SoRD and NRD indices. However, the manner in which FP error subtypes were incorporated into SoRD and NRD index calculations impacted the magnitudes of observed differences between and within the two age groups on SoRD and NRD indices. The present findings underline the importance of examining FP errors in assessments of recognition memory abilities, and using more refined indices of recognition discriminability to further elucidate the nature of age-related recognition memory impairment.     

Places of Information Generation: Bridging Pannenberg’s Logos and Deacon’s Emerging Semiosis

Bridging Wolfhart Pannenberg’s comprehensive twentieth-century systematic theology of Creation and Terrence Deacon’s very thorough scientific account of material and biological development and evolution results in an integrative view of Creation from Trinitarian relationality to biomolecular processes. Pannenberg’s understanding of Logos guides the investigation of the progressive unfolding of forms toward the key construct of information generation which Deacon’s theory of emergence explains as selection dynamics. Modeling both space and form as a place where activity generates information synthesizes Pannenberg’s complementary activities of Logos and Spirit with Deacon’s emergent dynamics and semiosis to develop generative distinctions among a field of systems as a key component of a scientifically plausible theological anthropology.     

Commitment to family roles: effects on managers' attitudes and performance

The authors tested the premise that family role commitment (i.e., marital role commitment, parental role commitment) has simultaneous negative and positive effects on managers' (N = 346) life satisfaction, career satisfaction, and performance through family-to-work interference and enhancement. The authors also explored whether psychological strain mediates the effects of interference and enhancement on outcomes. The authors expected family role commitment to reduce the favorability of outcomes by increasing interference. To the contrary, they found that neither marital nor parental role commitment was associated with increased interference. The authors expected family role commitment to improve outcomes by increasing enhancement. As expected, marital role commitment was associated with increased enhancement, which, in turn, seemed to reduce strain and strengthen outcomes. Parental role commitment was also associated with increased enhancement. However, parental role commitment had direct positive effects on outcomes that were more substantial than its indirect effects through enhancement. Overall, marital and parental role commitment had more benefits than costs.     

Monocular deprivation in adult mice alters visual acuity and single-unit activity

It has been discovered recently that monocular deprivation in young adult mice induces ocular dominance plasticity (ODP). This contradicts the traditional belief that ODP is restricted to a juvenile critical period. However, questions remain. ODP of young adults has been observed only using methods that are indirectly related to vision, and the plasticity of young adults appears diminished in comparison with juveniles. Therefore, we asked whether the newly discovered adult ODP broadly reflects plasticity of visual cortical function and whether it persists into full maturity. Single-unit activity is the standard physiological marker of visual cortical function. Using a more optimized protocol for recording single-units, we find evidence of adult ODP of single-units and show that it is most pronounced in deep cortical layers. Furthermore, using visual evoked potentials (VEP), we find that ODP is equally robust in young adults and mature adults and is observable after just one day of monocular deprivation. Finally, we find that monocular deprivation in adults changes spatial frequency thresholds of the VEP, decreasing the acuity of the deprived pathway and improving the acuity of the non-deprived pathway. Thus, in mice, the primary visual cortex is capable of remarkable adaptation throughout life.
