Neuropsychological Performance in Gulf War Era Veterans: Neuropsychological Symptom Reporting

Relationships between broad-based health symptoms and neuropsychological performance have been investigated previously in Gulf War (GW) veterans. However, very little has been done to assess relationships between severity of neuropsychological symptom complaints and performance on objective neuropsychological tests. In this study, relationships between level of self-reported neuropsychological symptom severity and objective neuropsychological performance measures were investigated. Participants included 240 veterans from three GW-era cohorts: GW-deployed veterans recruited from Ft. Devens, MA, (n = 142) and from New Orleans, LA (n = 51), and veterans deployed to Germany from a Maine National Guard unit (n = 47). Findings suggest that level of subjective neuropsychological complaints was associated primarily with mood symptoms in GW-era veterans. Among GW-deployed troops, high neuropsychological symptom reporters endorsed more tension, fatigue, and confusion and less vigor than those reporting fewer cognitive complaints. Current findings emphasize the importance of independent assessment of subjective symptoms and objective neuropsychological performance.     

In Search of the Supracultural: American Missionaries in the Gulf in 1920s–1930s

ABSTRACT

This article examines the dynamics of cultural encounters, with reference to the concept of Gustav Warneck (1834–1910) of the connections between mission and culture. It introduces the reader to the personal experience of the missionaries of the Arabian Mission, which was launched in 1889 and operated until 1973 in Basra, Amara, Bahrain, Kuwait and Muscat. While the Mission did not bring about the mass conversion of Muslims, its activities resulted in numerous everyday contacts with the local population. The article stresses that missionaries were a diverse group of individuals with different methods and aspirations, and explores how these diversities challenge a narrative on missions that usually reduces them to a homogenized missiology. Much of the content focuses on the 1920s–1930s, a very unique period in the Middle East, and seeks to show the way that the historical and local context shaped the diversities of missiology. Findings suggest that missionaries, as outsiders in the process of contacting the alien culture, often crossed cultural borders, and that these cultural encounters exhibited contrasting dynamics: the exclusion and rejection of local culture was accompanied by the ‘discovery’ of Islam and the search for ‘supracultural’ components of Islamic culture.     

Processing hyponymy in L1 and L2

This study examined the processing of hyponymy in L1 and two levels of performance (overall and high proficiency) in L2 in a group of Persian-English bilinguals. In two experiments, the same participants detected semantic relation in hyponymy pairs (i.e., hyponym-superordinate vs. superordinate-hyponym) in L1 (experiment 1) and L2 (experiment 2). The variables of pair type, stimulus onset asynchrony (SOA), language, and language proficiency were manipulated. Overall, the results showed that participants' median RTs and SDs were significantly greater in L2. This suggests that L2 processing in unbalanced bilinguals is less automatic than L1 processing. The findings of experiment 2 with the higher proficiency group showed a trend toward performance in L1 and therefore confirmed the prediction of the hierarchical model of bilingual memory that lexical processes in more-fluent bilinguals approximate those of L1 speakers. The results of the two experiments also showed that participants were significantly faster when presented with superordinate-hyponym word pairs than with hyponym-superordinate word pairs at 100-ms SOA in both L1 and L2 conditions. The results at 200-ms SOA, however, showed an opposite trend, although the results with L2 did not reach significance. This trend of results points to a possibility of automatic vs. strategic processing in the sense that participants' processing of hyponymy relation was more strategic than automatic at 200-ms SOA.     

Neuropsychological Performance in Gulf War Era Veterans: Motivational Factors and Effort

Assuming that the underlying etiology of unexplained health-related symptoms in returning Gulf War (GW) veterans is multifactorial, the possible role of feigning or exaggeration of symptoms is worth consideration as a contributing factor. The present study assessed the relationship between motivation to perform well during neuropsychological assessment and objective neuropsychological test performance. Motivation was measured as the score on a visual memory task (Test of Memory Malingering, TOMM) of low difficulty. Participants included 77 veterans from the cohorts of GW- (n = 58) and Germany-deployed (n = 19) GW-era veterans described in two other papers in this issue who were administered the TOMM. Most veterans earned perfect or near-perfect scores on the TOMM (48–50/50). Scores 47 were associated with lower scores on neuropsychological tasks assessing attention, executive functions, and memory. Variability in test performance within and between tasks measuring similar functions was also found in participants with lower TOMM scores.     

The Relationship Between Perceived Probability of Personal Harm and Distressful Reactions During the Gulf War

This study investigated the relationship between threat appraisal, distressful reactions, and coping strategies of Israeli civilians under missile attack during the Gulf War. During the war, 66 subjects were asked about their perceived probability of being hurt by the missiles. Additionally, they completed a questionnaire that measured their fears and symptoms during the war, the State Anxiety scale of the Endler Multidimensional Anxiety Scales, and the Coping Inventory for Stressful Situations (CISS, Endler & Parker, 1990). The results showed an inverted U-shaped relationship between perceived probability of being hurt and the anxiety measures. A similar curvilinear relationship was found between perceived probability of being hurt and emotion coping strategy. Furthermore, it was found that those who appraised the possibility of being hurt as very high, more often used avoidance coping. The results are discussed within the framework of stress theories and are related to other inverted U-shape relationships found between threat appraisal and stressful reactions.     

A pilot investigation into unimpaired and dyslexic Persian children's word naming and spelling: Implications for models of reading and counselling

There is now a growing body of research examining developmental dyslexia in different languages and writing systems. The phonologically transparent Persian orthography is normally transcribed with two distinct spellings, words spelled with vowels (letters) transcribed as a fixed part of the spelling (transparent) and words spelled with vowels (diacritics) omitted (opaque). This peculiarity of Persian would enable one to examine the impact of transparency, as well as the possible psychological factors associated with verbal punishment in Persian schools on the development of reading and spelling. Twenty-nine Persian children (22 male and 7 female) classified as being developmentally dyslexic (mean age 9.4, SD?=?1.4) were compared with 49 unimpaired male children (mean age 9, SD?=?1.3) on two main aspects of reading Persian opaque and transparent spellings, namely: Spelling and word naming. The results showed an expected impairment on all aspects of reading between unimpaired and children with dyslexia. However, performance of both groups of participants was impaired when performing tasks with opaque as opposed to transparent spellings. There was also a strong correlation between the recorded number of times the dyslexic child was verbally punished and the number of errors on the spelling and naming of transparent and opaque words. These results are supportive of the impact of spelling transparency, as well as psychological variables as factors in the development of reading and spelling.     

Persian speaking children's acquisition of relative clauses

The current study examined the acquisition of relative clauses (RCs) in Persian-speaking children. Persian is a relatively unique data point in crosslinguistic research in acquisition because it is a head-final language with post-nominal RCs. Children (N = 51) aged 2 to 7 years completed a picture-selection task that tested their comprehension of subject-, object-, and genitive-RCs. The results showed that the children experienced greater difficulty processing object and genitive RCs when compared to subject RCs, suggesting that the children have particular difficulty processing sentences with non-canonical word order. The results are discussed with reference to a number of theoretical accounts proposed to account for sentence difficulty.     

Translating the Stuttering Severity Instrument (SSI-3) into Persian: Response to Karimi, Nilipour, Shafiei and Howell

Karimi, Nilipour, Shafiei and Howell have raised some issues in regards to a study of which we were authors (Bakhtiar, Seifpanahi, Hossein, Ghanadzade & Packman, 2010). In that study, we reported the translation of the Stuttering Severity Instrument-3 (SSI-3) into Persian and reported its reliability when used with 12 Persian speaking preschool children who stutter, in Iran. Karimi et al. criticize our methods and claim that we did not specify that the translated test be used with preschoolers. In this response, we maintain that their criticisms of our methods are largely unfounded, especially the suggestion that we did not follow the WHO guidelines for translating questionnaires in our translation procedure. In addition, we show that we did in fact stipulate in our paper that the Persian SSI-3 should be used with preschoolers and that Karimi et al. misquoted us in their claim that we did not.
