Effects of computer‐based training on procedural modifications to standard functional analyses

Few studies have evaluated methods for training decision‐making when functional analysis data are undifferentiated. The current study evaluated computer‐based training to teach 20 graduate students to arrange functional analysis conditions, analyze functional analysis data, and implement procedural modifications. Participants were exposed to training materials using interactive software during a 1‐day session. Following the training, mean scores on the posttest, novel cases probe, and maintenance probe increased for all participants. These results replicate previous findings during a 1‐day session and include a measure of participant acceptability of the training. Recommendations for future research on computer‐based training and functional analysis are discussed.     

Ipsilesional Arm Aiming Movements After Stroke: Influence of the Degree of Contralesional Impairment

The authors examined the effects of the degree of impairment of the contralesional upper limb and the side of the hemispheric damage on ipsilesional upper limb performance in chronic stroke individuals. Right- and left-side stroke resulting in mild-to-severe impairment and healthy participants took part in simple and choice reaction time tasks involving aiming movements. The stroke individuals performed the aiming movements with the ipsilesional upper limb using a digitizing tablet to ipsi- or contralateral targets presented in a monitor. The global performance of the group with severe right hemispheric damage was worse than that of the other groups, indicating that the side of hemispheric damage and degree of motor impairment can adversely affect aiming movement performance.     

Performance of Faller and Nonfaller Older Adults on a Motor–Motor Interference Task

Typically, falls in older adults occur when 2 tasks are performed simultaneously, due to the increased motor demand required to maintain stability and attention to perform the other task. The authors' purpose was to investigate walking while grasping, transporting, and placing a dowel on a predetermined target while manipulating difficulty levels of the manual task. Faller and nonfaller older adults performed a walking block (manual tasks combined with gait) and a stationary block (upright stance combined with manual tasks). The manual task involved grasping, transporting, and placing the dowel over a target. The results showed that fallers underperformed when compared with nonfallers in the task of placing the dowel over the target. The main difference observed between the groups was found in the condition that required allocation of attention between tasks and greater accuracy in the final placement of the object. Fallers showed gait stability similar to the nonfallers, but fallers were less accurate than nonfallers in the object placement task, especially for the highest level of difficulty. Thus, fallers seem to use a stability-first strategy. Fallers had problems in executing the manual tasks, which suggests a more global change in motor behavior rather than specific changes to balance control.     

Spiritist Hospital Chaplaincy in Brazil: 5 Years of Documented Experience

Spiritist Hospital Chaplaincy in Brazil has been growing significantly in recent years, with the implementation of new services through the work of Spiritist Medical Associations (SMAs) in different regions of the country. This article describes the importance of historical interconnections from the advent of spiritism in the world and its introduction in Brazil to the emergence of Spiritist Hospital Chaplaincy in our country and presents the documented experience over 5 years of spiritist chaplain care, in the period from 2012 to 2016, guided by the SMA of Piracicaba at the Unimed Hospital of Piracicaba (São Paulo). We documented 41,914 visits to 13,983 inpatients and an analysis of these records allowed us to reflect on the importance of this service and confirm its expansion and acceptance by different contemporary religious beliefs.     

Attention-Deficit Hyperactivity Disorder (ADHD) Symptoms in Children Adopted from Poland and their Atypical Association Patterns: a Bayesian Approach

Although high rates of attention-deficit hyperactivity disorder (ADHD) symptoms have been observed among internationally adopted children, research on these symptoms in Polish adoptees is lacking. Therefore, we examined ADHD symptoms in Polish adoptees and their relationship to pre-adoptive risk factors, that is, time in institutional care, early deprivation, and prenatal alcohol exposure. We further compared the association patterns and gender distribution of ADHD symptoms in children adopted from Poland to those reported in the literature for ADHD symptoms in non-adopted children. Dutch adoptive parents of 121 Polish adoptees (52% boys; M _age = 10.9 years, range 6.2–15.6; M _ageadoption = 3.0 years, range 0.8–6.9) completed questionnaires regarding ADHD symptoms, pre-adoptive risk factors, attachment problems, conduct problems, and executive functioning deficits. Bayesian evaluation of informative hypotheses showed that Polish adoptees had increased levels of ADHD symptoms, compared to Dutch children in the general population. Time in institutional care, early deprivation, and prenatal alcohol exposure were not associated with ADHD symptoms. ADHD symptoms in Polish adoptees were more strongly associated with attachment problems and executive functioning deficits, but less strongly with conduct problems, compared to ADHD symptoms in non-adoptees. Furthermore, ADHD symptoms were more equally distributed among boys and girls than they are in non-adopted children. The findings indicate that Polish adoptees and their adoptive parents need special attention and support. The dissimilarities between ADHD symptoms in Polish adoptees and non-adoptees might indicate a different underlying causal mechanism, which may have important implications for clinical practice.     

I Think We’re Alone Now: Solitary Social Behaviors in Adolescents with Autism Spectrum Disorder

Research into emotional responsiveness in Autism Spectrum Disorder (ASD) has yielded mixed findings. Some studies report uniform, flat and emotionless expressions in ASD; others describe highly variable expressions that are as or even more intense than those of typically developing (TD) individuals. Variability in findings is likely due to differences in study design: some studies have examined posed (i.e., not spontaneous expressions) and others have examined spontaneous expressions in social contexts, during which individuals with ASD—by nature of the disorder—are likely to behave differently than their TD peers. To determine whether (and how) spontaneous facial expressions and other emotional responses are different from TD individuals, we video-recorded the spontaneous responses of children and adolescents with and without ASD (between the ages of 10 and 17 years) as they watched emotionally evocative videos in a non-social context. Researchers coded facial expressions for intensity, and noted the presence of laughter and other responsive vocalizations. Adolescents with ASD displayed more intense, frequent and varied spontaneous facial expressions than their TD peers. They also produced significantly more emotional vocalizations, including laughter. Individuals with ASD may display their emotions more frequently and more intensely than TD individuals when they are unencumbered by social pressure. Differences in the interpretation of the social setting and/or understanding of emotional display rules may also contribute to differences in emotional behaviors between groups.     

Response Mixture Modeling: Accounting for Heterogeneity in Item Characteristics across Response Times

In item response theory modeling of responses and response times, it is commonly assumed that the item responses have the same characteristics across the response times. However, heterogeneity might arise in the data if subjects resort to different response processes when solving the test items. These differences may be within-subject effects, that is, a subject might use a certain process on some of the items and a different process with different item characteristics on the other items. If the probability of using one process over the other process depends on the subject’s response time, within-subject heterogeneity of the item characteristics across the response times arises. In this paper, the method of response mixture modeling is presented to account for such heterogeneity. Contrary to traditional mixture modeling where the full response vectors are classified, response mixture modeling involves classification of the individual elements in the response vector. In a simulation study, the response mixture model is shown to be viable in terms of parameter recovery. In addition, the response mixture model is applied to a real dataset to illustrate its use in investigating within-subject heterogeneity in the item characteristics across response times.     

Brexit or Bremain? A person and social analysis of voting decisions in the EU referendum

The period following UK's European Union referendum in 2016 foreshadows significant social and political change in the UK. The current research draws on social psychological theories to empirically examine the drivers of voting decisions during the referendum. We report the results of a prospective study using structural equation modelling with data (N = 244) collected just before, and self‐reported voting behaviour immediately following (N = 197), the European Union referendum. We employ a person and social approach to examine the additive roles of worldview, conservatism, social identity, and intergroup threat as predictors of voting intentions and behaviour. Results showed that person factors (worldview and conservatism) predicted voting intentions through social factors (European identity and realistic threat) and that intentions predicted behaviour. The results highlight the importance of addressing threat‐based intergroup rhetoric and the potential of common in‐group identity to mitigate psychological threat.
