An alternative to grapheme-phoneme conversion rules?

When orthographic factors were tightly controlled in a lexical decision task, it was observed that orthographic similarity rather than homophony with a word led to increased reaction times to nonwords. This result suggested that the pseudohomophone effect is not a phonological effect. Instead, a conversion of the graphemes of a stimulus item into different graphemes via a set of grapheme-grapheme conversion rules was supported. When phonological factors were tightly controlled and orthographic similarity varied, evidence for the existence of grapheme-grapheme rules was provided in both a lexical decision task and a task in which subjects were required to say whether an item was pronounced in the same way as a word. Even in the latter task, in which the likelihood of phonological recoding was optimized, it appeared that grapheme-phoneme rules were rarely, if ever, used.     

Differences in Unit Cohesion and Combat-Related Mental Health Problems Based on Attachment Styles in US Military Veterans

This study explored the differences in perceived unit cohesion, trauma symptoms, depression symptoms, and anxiety symptoms controlling for childhood trauma, based on attachment style in US military veterans. Previous studies have reported that higher levels of military unit cohesion, bonding through the social relationships between service members and their larger units, and secure attachment, are negatively associated with trauma symptoms, depression symptoms, and anxiety symptoms in veterans. This study examined mental health distress symptoms as well as military unit cohesion across attachment styles. Results suggest mean differences in trauma symptoms, depression symptoms, and anxiety symptoms across attachment styles. However, there was no difference in perceived unit cohesion across the four attachment styles. Those using fearful-avoidant attachment styles reported the highest mean trauma, depression, and anxiety symptoms followed by those using a dismissing-avoidant attachment style. Those using a secure attachment style reported the least mean trauma, depression, and anxiety symptoms. Implications for assessing and treating avoidant type attachment styles are discussed.     

Assessment of Current Genetic Counselor Practices in Post-Visit Written Communications to Patients

Providing patients with post-visit written communication (PVWC) is a long-standing component of genetic counseling. However the depiction of this practice in today’s clinical landscape is limited. To better describe this practice, we surveyed practicing clinical genetic counselors to ask if they send post-visit communications to patients and if so, what are the types, the average length, and the average time spent writing. They were also asked the perceived purpose of providing PVWC, if/how the practice has changed over time, and factors influencing the practice. Eighty three percent (233/280) of participants reported sending patients PVWC. Of those, 93% sent at least one communication written in patient-friendly language. The type of communication varied by specialty. Prenatal genetic counselors were less likely to send patient-specific letters and hybrid letters (defined as letters with content intended for both a physician and a patient) than those in cancer genetics (p = 0.010, p = 0.001, respectively) or pediatric genetics (p = 0.001, p = 0.004, respectively). Prenatal genetic counselors spent less time on average writing post-visit communications (19.0 min) relative to those in cancer and pediatric genetics (30.6 min, p = 0.027 and 37.7 min, p = 0.001, respectively). The most commonly cited purpose for sending PVWC was to provide patients a formal account of what happened during the appointment. These data suggest PWVC are still regularly sent to patients but the practice is variable and is influenced by numerous factors including specialty, years of experience, and time constraints.     

Long-term meditation: the relationship between cognitive processes,thinking styles and mindfulness

The aim of this study is to examine the relationship between meditation and cognitive functions. More in depth the purpose is to demonstrate that long-term meditation practice improves attention skills and cognitive flexibility. Eighteen long-term meditation practitioners were compared to a matched control group, who never practiced meditation. Each subject was tested, using computerized software (Presentation Software 9.90), which measured: attention, visual search abilities, working memory and Stroop’s interference tasks. Furthermore, we examined the relationship between long-term meditation practice, mindfulness skills and thinking styles, namely styles of processing information. The results showed significant differences between the two groups, demonstrating that long-term meditation is linked to improvements of attentional functions, working memory and cognitive flexibility.     

Word category and verb--argument structure information in the dynamics of parsing

One of the core issues in psycholinguistic research concerns the relationship between word category information and verb-argument structure (e.g. transitivity) information of verbs in the process of sentence parsing. In two experiments (visual versus auditory presentation) using event-related brain potentials (ERPs), we addressed this question by presenting sentences in which the critical word simultaneously realized both a word category and a transitivity violation. ERPs for sentences with both types of violation clustered with the patterns for sentences with a word category violation only, but were different from the patterns elicited by argument structure violations in isolation, since only the latter elicited an N400 ERP component. The finding that an argument structure violation evoked an N400 only if the phrase structure of the respective sentence was correct suggests that a successful integration of the word category information of a verb functionally precedes the application of its argument structure information.     

A cross-culturally standardized set of pictures for younger and older adults: American and Chinese norms for name agreement,concept agreement,and familiarity

The present study presents normative measures for 260 line drawings of everyday objects, found in Snodgrass and Vanderwart (1980), viewed by individuals in China and the United States. Within each cultural group, name agreement, concept agreement, and familiarity measures were obtained separately for younger adults and older adults. For a subset of 57 pictures (22%), there was equivalence in both name agreement and concept agreement, and for an additional subset of 29 pictures (11%), there was nonequivalent name agreement but equivalent concept agreement, across all culture-by-age groups. The data indicate substantial differences across culture-by-age groups in name agreement percentages and number of distinct name responses provided. We discovered significant differences between older and younger American adults in both name agreement percentages (67 pictures, or 26%) and concept agreement percentages (44 pictures, or 17%). Written naming responses collected for the entire set of Snodgrass and Vanderwart pictures showed shifts in both naming and concept agreement percentages over the intervening decades: Although correlations in name agreement were strong (r = .71,p < .001) between our younger American samples and those of Snodgrass and Vanderwart, name agreement percentages have changed for a substantial proportion (33%) of the 260 pictures; moreover, 63% of the stimuli for which Snodgrass and Vanderwart reported concept agreement now appear to differ. We provide comprehensive comparison statistics and tests for both the present study and prior ones, finding differences across numerous item-level measures. The corpus of data suggests that substantial differences in all measures can be found across age as well as culture, so that unequivocal conclusions with respect to cross-cultural or age-related differences in cognition can be made only when appropriate stimuli are selected for studies. Data for all 260 pictures, for each of the four groups, and all supporting materials and tests are freely archived athttp://agingmind.cns.uiuc.edu/Pict Norms.

Neuroimaging studies in eating disorders

The understanding of the eating disorders (EDs) anorexia (AN) and bulimia nervosa (BN) has undergone remarkable advancements in the past decade. Most studies that have been done in AN show brain gray and white matter volume loss during the ill state that, at least in part, remit with recovery. Similar patterns occur for brain phospholipids assessed using magnet resonance spectroscopy (MRS). Imaging studies have been used to provide functional information regarding serotonin neuroreceptor dynamics, regional cerebral blood flow, or cerebral glucose metabolism. Such studies have implicated cingulate, frontal, temporal, and parietal regions in AN. Investigators have found that challenges such as food and body image distortions may activate some of these regions, raising the possibility that such studies may shed light on puzzling AN symptoms, such as body image distortions or extremes of appetitive behaviors. Emerging data suggest these disturbances persist after recovery from AN, suggesting the possibility that these are traits that may create a vulnerability to develop an ED. While fewer studies have been done in BN or binge eating disorder, there may be disturbances of serotonin metabolism in similar brain regions. Taken together, these findings give promise for future investigations with the hope of delineating brain pathways that contribute to the etiology of EDs
