Executive functioning and its relation to ASD and ADHD symptomatology in 22q11.2 deletion syndrome*

Children with 22q11.2 deletion syndrome (22q11DS; velo-cardio-facial-syndrome) are at risk for the developmental disorders, attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD). In this study, the relation between executive functioning (EF) and the severity of ADHD and ASD symptoms is examined, since EF is known to be important in relation to emotional and behavioral problems. The participants consist of 58 children (38 females) with a mean age of 13.5 years (SD 2.6). Standardized assessment was used to evaluate the severity of ASD and ADHD symptomatology. The major aspects of EF, i.e., cognitive flexibility, inhibition, sustained attention, distractibility, working memory and reaction speed, were evaluated. The profile of EF in 22q11DS was found to be characterized by weaker performance compared to the norms on all subdomains of EF. Poor cognitive flexibility and inhibition, as well as high distractibility, were found to be related to more severe ASD symptoms, while poor quality of sustained attention and high distractibility were found to be related to more severe ADHD symptoms. It is concluded that children with 22q11DS experience impairments in EF, and that the degree of impairment on specific EF subdomains is related to the severity of ASD and/or ADHD symptomatology. These results may help in defining the mediating role of neurocognitive dysfunctions in the development of social and behavioral problems in 22q11DS.     

Relationships Between Cortisol,Optimism, and Perseverance Measured in Two Military Settings

Optimism and perseverance are 2 important assets for soldiers to be able to perform competently in high-risk environments and to complete complex and stressful tasks. Traditionally, optimism is measured using questionnaires and most frequently in a retrospective manner, for example, after a mission is completed. As such, ability to persevere in challenging environments is generally taken into account when it is too late, that is, when the soldier is showing severe signs of deficiency or failing to persevere. Therefore, there is a need for more objective measurements with which to predict perseverance. We conducted and present 2 studies in which the hormone cortisol seems to play a key role, relating with optimism, and possibly predicting perseverance. In the first study, we measured cortisol levels during a computer-simulated military training mission. A significant correlation between cortisol levels and optimism measured by the revised Life Orientation Test (LOT-R) Scale was found. In the second study, we followed 29 recruits through a demanding military training course required for joining the Dutch Air Mobile Brigade. The recruits who persevered and completed the course had a higher cortisol response to a stressful training event compared with those who leave the course. A regression model showed that a combination of the soldiers’ optimism and cortisol response best predicted perseverance. This study shows that a combination of attitudinal instruments and a biomarker has potential for predicting military training course attrition.     

Stability and change in burnout: A 10‐year follow‐up study among primary care physicians

The aim of the present study is (1) to investigate the impact of patient demands on primary care physicians’ burnout and (2) to examine the stability and change of burnout across time. Participants were drawn from the official Dutch registration system for primary health care, and longitudinal panel data (n= 165) from three waves with a 5‐year time interval were used. They filled in the Maslach Burnout Inventory (MBI) and a validated scale for the assessment of patient demands. The results of various stability and change models that were tested using structural equation modelling (SEM) indicated that demanding patient contacts lead to increased burnout among physicians. In addition, the findings suggested that about one quarter of the variance in physician's actual burnout levels across one decade is accounted for by a stable component, whereas about three quarters is accounted for by a change component. Hence, physician burnout seems to be a rather chronic condition that may be aggravated by exposure to demanding patients.     

Linking resident behavior to dementia care communication: effects of emotional tone

Care for older adults with dementia is complicated by behaviors such as verbal and physical aggression and withdrawal that disrupt and increase the costs of providing care. These behaviors, referred to as resistiveness to care (RTC), have been linked to staff elderspeak communication, measured by behaviorally coded explicit behaviors. This study examined videotapes of nursing home (NH) residents with dementia interacting with staff during bathing to explore the relationships between implicit messages communicated by nursing staff and resident RTC behavior.Implicit messages in nursing staff communication were rated using the Emotional Tone Rating Scale by naïve coders. Associations between implicit ratings of care, respect, and control were analyzed in relation to RTC scale scores. Highly controlling communication was significantly correlated with increased resident RTC (r = .49, p < .05). Associations between the care and respect dimensions of communication were not significantly correlated with RTC; however, trends in hypothesized directions were identified. The association between emotional tone and RTC found in this study suggests that it is an important factor in care. Understanding affective messages is a first step in modifying these implicit messages conveyed during staff-resident communication. Research is needed to confirm these findings and to identify and test interventions to teach staff to reduce controlling messages that will to reduce RTC and improve care.     

Patterns of resource allocation are reliable among younger and older readers

Younger and older adults read short expository passages across 2 times of measurement for subsequent comprehension or recall. Regression analysis was used to decompose word-by-word reading times into resources allocated to word- and textbase-level processes. Readers were more sensitive to these demands when reading for recall than when reading for comprehension. Patterns of resource allocation showed good test-retest reliabilities and were predictive of memory performance. Within age group, resource allocation parameters were not systematically correlated with other individual-difference measures, suggesting that strategies of on-line resource allocation may be a unique source of individual differences in determining comprehension of and memory for text. Age differences in allocation patterns appeared to reflect general slowing among the older adults. Because older adults showed equivalent memory performance to that of younger readers, the reading time data may represent the on-line resource allocation needed for comparable outcomes among older and younger readers.     

Sense of Community in Clubhouse Programs: Member and Staff Concepts

Psychological sense of community within psychosocial rehabilitation clubhouse programs was examined using concept mapping with 18 members and 18 staff from 10 programs. Members identified four concepts: Recovery, social connections, membership, and tasks and roles. Members described hope and healing as aspects of recovery. Members' views on sense of community focused on the rehabilitation and social nature of the program. Staff also identified four concepts: Affiliation and support for members, shared experiences, clubhouse organization, and task and roles. The staff concept of clubhouse organization, which incorporated the ideas of leadership and organization of physical space and the concept of task and roles, was based on ideas of shared responsibility and clubhouse procedures. Staffs' views on sense of community strongly reflected their formal training in clubhouse principles. The relation of these concepts to McMillan and Chavis' theoretical framework for sense of community is discussed and recommendations for practice provided. Sandra E. Herman is now an independent program evaluation consultant. Catherine Ferguson is now an independent consultant on psychosocial programs.     

Bottlenosed dolphins (Tursiops truncatus) comprehend the referent of both static and dynamic human gazing and pointing in an object-choice task

The authors tested 2 bottlenosed dolphins (Tursiops truncatus) for their understanding of human-directed gazing or pointing in a 2-alternative object-choice task. A dolphin watched a human informant either gazing at or pointing toward 1 of 2 laterally placed objects and was required to perform a previously indicated action to that object. Both static and dynamic gaze, as well as static and dynamic direct points and cross-body points, yielded errorless or nearly errorless performance. Gaze with the informant's torso obscured (only the head was shown) produced no performance decrement, but gaze with eyes only resulted in chance performance. The results revealed spontaneous understanding of human gaze accomplished through head orientation, with or without the human informant's eyes obscured, and demonstrated that gaze-directed cues were as effective as point-directed cues in the object-choice task.
