Responsiveness in Interactions of Mothers and Sons with ADHD: Relations to Maternal and Child Characteristics

We observed mother–child interactions, at baseline, in 136 families of 7–10-year-old boys with attention-deficit/hyperactivity disorder (ADHD) who were part of a large clinical trial, the Multimodal Treatment Study of Children with ADHD. Independent coders rated stylistic aspects of maternal behavior and factor analyses revealed a responsiveness factor that included overall responsiveness and sensitivity to the child, warmth and acceptance, and appropriate control. We examined relations between maternal responsiveness and (a) maternal depressive symptoms and maternal childhood ADHD symptoms, and (b) boys' ADHD and conduct problem symptoms. Controlling for all other variables, maternal responsiveness displayed a unique negative association with mother-reported child conduct problems, but not with child ADHD symptoms, and also was negatively related to maternal depressive symptoms. We discuss the unique association between mother-reported child conduct problems and parenting, and note the utility of studying parenting style in families of children with ADHD. We describe the results within the framework of a transactional model.     

IQ on the rise: the Flynn effect in rural Kenyan children

Abstract - Multiple studies have documented significant IQ gains over time, a phenomenon labeled the Flynn effect. Data from 20 industrialized nations show massive IQ gains over time, most notably in culturally reduced tests like the Raven's Progressive Matrices. To our knowledge, however, this is the first study to document the Flynn effect in a rural area of a developing country. Data for this project were collected during two large studies in Embu, Kenya, in 1984 and 1998. Results strongly support a Flynn effect over this 14-year period, with the most significant gains found in Raven's matrices. Previously hypothesized explanations (e.g., improved nutrition; increased environmental complexity; and family, parental, school, and methodological factors) for the Flynn effect are evaluated for their relevance in this community, and other potential factors are reviewed. The hypotheses that resonate best with our findings are those related to parents' literacy, family structure, and children's nutrition and health.     

The role of perceptual load in processing distractor faces

It has been established that successful ignoring of irrelevant distractors depends on the extent to which the current task loads attention. However, the previous load studies have typically employed neutral distractor stimuli (e.g., letters). In the experiments reported here, we examined whether the perception of irrelevant distractor faces would show the same effects. We manipulated attentional load in a relevant task of name search by varying the search set size and found that whereas congruency effects from meaningful nonface distractors were eliminated by higher search load, interference from distractor faces was entirely unaffected by search load. These results support the idea that face processing may be mandatory and generalize the load theory to the processing of meaningful and more complex nonface distractors.     

Explaining the Relationship between Religiosity and Political Participation: The Mediating Roles of Transcendent Accountability and Religiopolitical Awareness

Prior research tends to find a positive relationship between religiosity and political participation. Explanations of this relationship have focused mostly on religiosity-generated organizational resources (e.g., civic skills), while paying less attention to psychological resources. We simultaneously examined different aspects of religiosity (belief, behavior, and belonging) and political participation (electoral and nonelectoral) in a structural equation model with two psychological resources as mediators: (1) “transcendent accountability”—seeing oneself as responsible to God or a higher power for one's impact on other people and the environment, and (2) “religiopolitical awareness”—perceiving the influence of one's religion and/or spirituality on one's political views and activities. Results from analyzing survey data from a US representative sample showed that transcendent accountability and religiopolitical awareness, whether together or awareness only, mediated positive relationships between religiosity (belief, private and public behaviors, and membership) and political participation (voting and other political activity), highlighting key psychological motivators of political participation.     

Cluster analysis reveals distinct patterns of saccade impairment and their relation to cognitive profiles in Parkinson's disease

Saccade performance has been reported to be altered in Parkinson's disease (PD), however, with a large variability between studies as both motor and cognitive impairment interfere with oculomotor control. The aim of this study was to identify different patterns in saccade alterations in PD using a data-driven approach and to explore their relationship with cognitive phenotypes. Sixty-one participants with PD and 25 controls performed eye-tracking (horizontal and vertical prosaccades, antisaccades) and neuropsychological testing. Hierarchical cluster analysis was applied to the eye-tracking data to subsequently compare the clusters based on demographical, clinical and cognitive characteristics. The three identified clusters of saccade alterations differed in cognitive profiles from healthy controls, but not in PD-related motor symptoms or demographics. The rate of directive errors in the antisaccade task was increased in clusters 1 and 2. Further, cluster 1 was defined by a general disinhibition of reflexive saccades and executive dysfunction in the neuropsychological evaluation. In cluster 2, prolonged saccade latencies and hypometria were accompanied by multidomain cognitive impairment. The cluster 3 showed increased antisaccade latency and vertical hypometria despite lack of evidence for cognitive impairment. Our results suggest that there may be at least two opposing patterns of saccade alterations associated with cognitive impairment in PD, which may explain some of the contradictory results of previous studies.     

Teaching multiply controlled intraverbals to children and adolescents with autism spectrum disorders

Reciprocal conversations, instructional activities, and other social interactions are replete with multiply controlled intraverbals, examples of which have been conceptualized in terms of conditional discriminations. Although the acquisition of conditional discriminations has been examined extensively in the behavior‐analytic literature, little research has evaluated procedures to establish multiply controlled intraverbals. Thus, the purpose of this investigation was to evaluate the effects of procedures based on conditional discrimination training on the acquisition of multiply controlled intraverbals with 7 participants who had been diagnosed with autism spectrum disorders. We evaluated the effects of prompt delay with error correction, a differential observing response (DOR), and a DOR plus blocked trials on the acquisition of intraverbals using a multiple baseline design. Accuracy of intraverbal performance increased for at least 1 set of stimuli for all participants under prompt delay with error correction conditions; however, 4 participants required additional teaching (i.e., DOR, modified DOR, modified prompt delay with error correction). Based on these findings, when prompt delay with error correction is not sufficient to establish multiply controlled intraverbals, prompted DORs may be an effective alternative.     

Improved resiliency and well‐being among military personnel in a Swedish Naval Force after a counter‐piracy operation off the coast of Somalia

The aim of this study was to explore: (1) how the psychological health of the members of the first European Union Naval Force (ME01) was affected by international deployment off the coast of Somalia; and (2) if and how organizational and personal factors (e.g., type of personnel category, previous experiences, and resilience) affected their psychological health and well‐being post‐deployment. The study had an exploratory longitudinal design, where the participants were assessed both before and after deployment (i.e., T1 and T2). The participants (n = 129, 120 men, 9 women) were equally distributed between officers (n = 68; 64 men, 4 women) and sailors (n = 61; 56 men, 5 women). The members' average age was 31 years, ranging from 20 to 61. For the majority (78%) ME01 was their first international deployment and officers were, in general, more experienced than sailors. The overall results showed that the members' reported a positive experience with improved resilience and well‐being (e.g., sense of coherence). However, the result also showed that type of personnel category (i.e., officer or sailor) affected their psychological health. Why and how these differences among military personnel arise is discussed, but deserves further attention.     

The Expression of Posttraumatic Stress Symptoms in Daily Life: A Review of Experience Sampling Methodology and Daily Diary Studies

This review examined the assessment of posttraumatic stress symptoms (PTSS) in daily life using experience sampling methodology (ESM)/ecological momentary assessment (EMA) and daily diary studies in adult samples. Fifteen peer-reviewed studies were identified and categorized into areas of total PTSD/multiple PTSS (studies including three or more symptom clusters), intrusive memories, and mood and anxiety symptoms. Overall, ESM and the daily diary method proved feasible for assessing the real-world expression of PTSS, resulted in minimal reactivity, and offered a number of advantages over classical assessment. Even within the two measurement types of ESM and daily diary, there was great variability in study design and analysis. The benefits and limitations of the different approaches are discussed. Different themes in content emerged as well, such as coping strategies and affective instability throughout the course of a day. Gaps in our current understanding are highlighted and suggestions for methodology and future areas of research are proposed.
