The Effect of Non-sentential Context Prosody on Homographs’ Lexical Activation in Persian

This study examines the effect of non-sentential context prosody pattern on lexical activation in Persian. For this purpose a questionnaire including target and non-target words is used. The target words are homographs with two possible stress patterns belonging to different syntactic categories. Participants are asked to read out the words aloud and note the first word that comes to their mind. The results show that by reading the target words, both meanings of the target words are activated in mind and the prosodic pattern of the non-sentential preceding context does not affect the activation of the other stress pattern meaning. This result suggests that the metrical prosodic pattern of non-sentential context is not a strong constraint to determine which meaning of the target word must be activated. The experiment also illustrates that the stress pattern used to read the target words does not necessarily matches the stress pattern of the target word which relates to the written word. These findings confirm Swinney (Verb Learn Verb Behav 18:645–665, 1979) and Elston-Güttler and Friederici’s (J Mem Lang 52(2):256–283, 2005) finding that both meanings of an ambiguous word are accessed at the first stage. This study shows that in lack of semantic context, Persian natives behave homographs as ambiguous words and there is no bias towards preferring one meaning over another.     

Neurocognitive correlates of white matter quality in adolescent substance users

Background

Progressive myelination during adolescence implicates an increased vulnerability to neurotoxic substances and enduring neurocognitive consequences. This study examined the cognitive manifestations of altered white matter microstructure in chronic marijuana and alcohol-using (MJ + ALC) adolescents.

Methods

Thirty-six MJ + ALC adolescents (ages 16–19) and 36 demographically similar controls were evaluated with diffusion tensor imaging (Bava et al., 2009) and neurocognitive tests. Regions of group difference in fractional anisotropy (FA) and mean diffusivity (MD) were analyzed in relation to cognitive performance.

Results

In users, lower FA in temporal areas related to poorer performance on attention, working memory, and speeded processing tasks. Among regions where users had higher FA than controls, occipital FA was positively associated with working memory and complex visuomotor sequencing, whereas FA in anterior regions was negatively associated with verbal memory performance.

Conclusions

Findings suggest differential influences of white matter development on cognition in MJ + ALC using adolescents than in non-using peers. Neuroadaptation may reflect additive and subtractive responses to substance use that are complicated by competing maturational processes.     

Adapting Cognitive Processing Therapy for PTSD for People With Disabilities: A Case Study With a U.S. Veteran

Many veterans receiving treatment for PTSD in the VA health care system are also living with a disability and utilize assistive technologies for communication and/or mobility. While evidence-based treatments for PTSD have been disseminated in VA hospitals nationwide, clinicians may have concerns about implementing these treatments with people with disabilities or question how to adapt evidence-based protocols to facilitate successful outcomes. This clinical case study details the treatment of a 48-year-old male U.S. veteran with a diagnosis of military-related PTSD and significant functional and communicative complexities characteristic of locked-in syndrome. The study implemented an adapted protocol of Cognitive Processing Therapy (CPT), a first-line evidence-based psychotherapy for PTSD with unknown application to people with disabilities. CPT protocol structure, length, and delivery was adapted to accommodate the veteran’s assistive devices and functional abilities. The veteran experienced a clinically significant reduction in PTSD symptoms over the course of treatment, suggesting successful application of the adapted protocol. In addition to symptom reduction, the veteran reported advances in his ability to tolerate emotional distress while engaged in goal-directed behavior and improved interpersonal functioning. Results suggest that CPT can be adapted and effective in instances where the presence of disability and multiple assistive technologies impact standard treatment implementation. This information is valuable in its potential ability to make evidence-based psychotherapies more accessible and disability-sensitive. Clinical recommendations for using and adapting CPT for people with disabilities are provided.     

Spiritual Health and Outcomes in Muslim ICU Patients: A Nationwide Cross-Sectional Study

The aim of the present study is to describe how religiosity and spirituality affect the psychiatric morbidity of Muslim intensive care unit (ICU) patients. We conducted a prospective nationwide cross-sectional study of ICU patients discharged from 45 medical centers spanning 31 proivinces in Iran. Adults (age ≥ 18 years) admitted to the ICU and treated with invasive mechanical ventilation were eligible. Nine validated survey tools were administered to detect direct and indirect associations between spiritual health (SH) and depression, anxiety, and post-traumatic disorder. The Hospital Anxiety and Depression Scale (HADS), Impact of Event Scale—Revised (IES-R), Post-Traumatic Stress Syndrome 14 question (PTSS-14) quality-of-life (QoL), and quality of patient to physician or nurse communication (PP-QoC and PN-QoC) scales were modeled through two mediators by structural equation modeling (SEM). Sex, ICU type, LOS, and APACHE II score were added in the independent variable list. 338 eligible patients were discharged from the ICUs during the study period. 56 were excluded (clinical status), and 282 were administered the survey. 278 returned it, with 272 complete and 6 partial responses. SH displayed no direct or indirect association to QoL. SH was indirectly associated with decreased depression and anxiety (B = ? 0.081, p < 0.05) via PP-QoC mediator. Both direct and indirect positive associations were observed between SH and IES-R (B = 0.293, p < 0.05; via PP-QoC) and PTSS-14 scores (B = 0.267, p < 0.001; via PP-QoC). Medical ICU location was associated with decreased PTSS-14 scores via the same mediator. In this survey of Muslim ICU patients treated with invasive mechanical ventilation, SH correlated with decreased depression and anxiety, but paradoxically increased post-traumatic stress. The most influential mediator was patient–physician quality-of-communication.     

Ayodhya and the Hindu resurgence

It is usually accepted that although cosmological references in the early Pali Buddhist texts refer metaphorically to meditative states of mind, they should at the same time be understood as referring in literal terms to an externally existent cosmos. Because the ontological status of the cosmos appears to be tangential to what the Buddha taught, however, it is not clear that this literal interpretation is appropriate. From a study of the early textual material, this paper suggests that an alternative understanding of the cosmos is more compatible with the Buddha's teachings.     

Perceived ownership impacts reward evaluation within medial-frontal cortex

Ownership is a powerful construct. Indeed, in a series of recent studies, perceived ownership has been shown to increase attentional capacity, facilitate a memorial advantage, and elicit positive attitudes. Here, we sought to determine whether self-relevance would bias reward evaluation systems within the brain. To accomplish this, we had participants complete a simple gambling task during which they could “win” or “lose” prizes for themselves or for someone else, while electroencephalographic data were recorded. Our results indicated that the amplitude of the feedback error-related negativity, a component of the event-related brain potential sensitive to reward evaluation, was diminished when participants were not gambling for themselves. Furthermore, our data suggest that the ownership cues that indicated who would win or lose a given gamble either were processed as a potential for an increase in utility (i.e., gain: self-gambles) or were processed in a nonutilitarian manner (other-gambles). Importantly, our results suggest that the medial-frontal reward system is sensitive to perceived ownership, to the extent that it may not process changes in utility when they are not directly relevant to self.     

Personal Construct System of a Runaway Adolescent: An Illustrative Case Study

Personal constructs of an 18-year-old adolescent were explored by the use of a repertory grid focusing on the domains of family, self, and world. Results indicated that the runaway adolescent construed his family in a negative and rejecting way, whereas important people outside the family were perceived in a more accepting and friendly manner. It was also found that although the young man construed himself in a positive manner, at the same time he perceived himself as aloof and distant from both family and nonfamily members. The findings indicate that a young adolescent's decision to run away from home and jump into the world of the unknown is the consequence of certain push factors in the home environment and pull factors in the external world. Results of the grid are discussed in light of key elements in construct space.     

Student mental health: how can psychiatrists better support the work of university medical centres and university counselling services?

Student psychiatric morbidity is rising. Whilst the influence of university counselling services is widely reported, NHS involvement by psychiatrists and general practitioners is not so well described. Counselling and mental health service providers for students at the University of Leeds were approached for numerical data and a university Group on Student Mental Health discussed the findings. The Student Counselling Centre, the University Medical Practice and a dedicated student psychiatric clinic have all seen a rise in referral rates. The University Medical Practice has also seen a rise in the prescribing of psychoactive medication. Collaborative links at the University of Leeds are explored and options for the future discussed. These include self-help over the internet, a research project to assess student mental health needs and the provision of a dedicated NHS psychiatric team for the university.
