Assessment of Executive Functions after Treatment of Childhood Acute Lymphoid Leukemia: a Systematic Review

Neuropsychology Review - Individuals treated for childhood acute lymphoblastic leukemia (ALL) have a high survival rate. This fact, however, may lead to neurocognitive impairments in survivors, as...     

Brain Gene Expression During REM Sleep Depends on Prior Waking Experience

In most mammalian species studied, two distinct and successive phases of sleep, slow wave (SW), and rapid eye movement (REM), can be recognized on the basis of their EEG profiles and associated behaviors. Both phases have been implicated in the offline sensorimotor processing of daytime events, but the molecular mechanisms remain elusive. We studied brain expression of the plasticity-associated immediate-early gene (IEG) zif-268 during SW and REM sleep in rats exposed to rich sensorimotor experience in the preceding waking period. Whereas nonexposed controls show generalized zif-268 down-regulation during SW and REM sleep, zif-268 is upregulated during REM sleep in the cerebral cortex and the hippocampus of exposed animals. We suggest that this phenomenon represents a window of increased neuronal plasticity during REM sleep that follows enriched waking experience.     

The mediating role of feelings of guilt in the relationship between burnout and the consumption of tobacco and alcohol

Earlier studies have shown that feelings of guilt appear to be involved in the burnout process. However, the exact nature of the relationship between burnout, feelings of guilt, and tobacco and alcohol use is unclear. The purpose of this study was to analyze the role of feelings of guilt in the relationship between burnout and the consumption of tobacco and alcohol. Role conflict, Role clarity, and Feedback were included as predictors of burnout. The sample of this cross‐sectional study consisted of 260 Chilean administration and customer service workers. Hypotheses were tested using a path model. The hypothesized model (i.e., Indolence to guilt to tobacco/alcohol use) showed an adequate data fit, including a mediator role of feelings of guilt in the relationship between burnout and alcohol use. The results of this study recommending taking into consideration the evaluation of feelings of guilt as a symptom of burnout in order to develop a more reliable diagnosis of burnout syndrome and its consequences.     

Integrating spatial information across experiences

The current study examined the potential influence of existing spatial knowledge on the coding of new spatial information. In the Main experiment, participants learned the locations of five objects before completing a perspective-taking task. Subsequently, they studied the same five objects and five additional objects from a new location before completing a second perspective-taking task. Task performance following the first learning phase was best from perspectives aligned with the learning view. However, following the second learning phase, performance was best from the perspective aligned with the second view. A supplementary manipulation increased the salience of the initial view through environmental structure as well as the number of objects present. Results indicated that the initial learning view was preferred throughout the experiment. The role of assimilation and accommodation mechanisms in spatial memory, and the conditions under which they occur, are discussed.     

A Review of “Telling Children About the Past: An Interdisciplinary Perspective”

ABSTRACT

World Heritage listing aims to provide protection for the planet's most precious natural and cultural sites. Listing can also increase awareness and visitation, particularly as presentation is a tenet of the World Heritage Convention. Visitor management, based on empirical research, is therefore required to ensure an appropriate balance between these, often conflicting, obligations of protection and presentation. Many World Heritage visitor studies have considered iconic, accessible, international tourism destinations that are facing issues of visitor congestion and threatened heritage values. To provide a balanced understanding of World Heritage tourism, further research is required, particularly focusing on various site types and different World Heritage visitors. To support this agenda, this research identified a lesser-known World Heritage Area with low visitation levels, developed a self-administered visitor questionnaire appropriate for the site, and studied the visitor characteristics, motivations, and experiences. Findings regarding visitors to the remote Riversleigh World Heritage Site in Australia indicate that these visitors differ from visitors to iconic World Heritage Areas, although motivational aspects are similar. The outcomes of the research have informed the visitor interpretive plan developed by the state government responsible for delivering on the Convention requirements for the Riversleigh World Heritage Site, and provide a visitor questionnaire that can be used, or further developed, for other sites.     

Social Validity of a Training and Coaching Program for Parents of Children With Autism Spectrum Disorder on a Waiting List for Early Behavioral Intervention

Due to limited public resources, many children with autism spectrum disorder and their families must wait several months, if not years, to access early behavioral intervention (EBI) services. Service providers must thus develop alternative support models to assist families placed on waiting lists. The present study assessed the social validity of one such initiative, a training and coaching program for parents whose children had been put on a waiting list for EBI services. This program consisted of group training sessions on strategies to cope with their child’s disorder based on applied behavioral analysis and on one-hour, weekly follow-up meetings to support parents’ interventions with their child over the course of 12 months. Social validity was assessed through parental satisfaction with this program and their perception of its effects on themselves, the family, the child, and parental stress. The 94 participants were generally satisfied with the program overall, although they wished for more frequent and intensive interventions. They reported that the program had positive effects on their psychological well-being, their family’s quality of life, and their child’s behavior. However, parenting stress levels were found to have increased over the 12-month period. These results demonstrate that training and individually supporting parents can be beneficial for families of children with ASD who cannot have access to early behavioral intervention immediately upon receiving a diagnosis. Importantly, however, these lower-cost, parent-focused programs cannot be considered a substitute for more intensive and children-driven services.     

A shared past and a common future: the Portuguese colonial war and the dynamics of group-based guilt

In the present study we examine feelings of group-based guilt among Portuguese people in relation to the Portuguese colonial war, and their consequences for social behaviour. Specifically, we focus on the way Portuguese university students identify with their national group and the outgroup and their feelings of group-based guilt regarding their group's past misdeeds during the colonial period. The consequences of group-based guilt are also analyzed. 130 Portuguese university students answered a questionnaire and results show that students feel low levels of group-based guilt in relation to this period. Our results show that ingroup glorification is positively related with the use of cognitions to justify the ingroup's behaviour, presumably to avoid responsibility for the harm committed by the ingroup. Outgroup identification correlates with compensatory behavioural intentions and openness to negative information about the colonial war. As expected, feelings of group-based guilt show a significant correlation with compensatory behavioural intentions. Links between political orientation, ingroup attachment and glorification, exonerating cognitions and group-based guilt are analyzed and their implications for intergroup relations are discussed.     

Brazelton Neonatal Behavioral Assessment Scale: A psychometric study in a Portuguese sample

BackgroundThe Neonatal Behavioral Assessment Scale (NBAS, Brazelton &; Nugent, 1995) is an instrument conceived to observe the neonatal neurobehavior. Data analysis is usually performed by organizing items into groups. The most widely used data reduction for the NBAS was developed by Lester, Als, and Brazelton (1982).ObjectiveExamine the psychometric properties of the NBAS items in a sample of 213 Portuguese infants.MethodThe NBAS was performed in the first week of infant life (3 days ± 2) and in the seventh week of life (52 days ± 5).ResultsPrincipal component analyses yielded a solution of four components explaining 55.13% of total variance. Construct validity was supported by better neurobehavioral performance of 7-week-old infants compared with 1-week-old infants.ConclusionChanges in the NBAS structure for the Portuguese sample are suggested compared to Lester factors in order to reach better internal consistency of the scale.
