The neural substrates of action retrieval: An examination of semantic and visual routes to action

We report three PET experiments that examine the neural substrates of the conceptual components of action retrieval. In all three experiments, subjects made action or screen-size decisions to familiar objects presented either as pictures or written words (the names ofthe objects). In Experiment 1, a third task was included, requiring a decision on the real-life size of the stimuli. In Experiment 2, a third stimulus type was included, with action and size decisions also performed on pictures of meaningless novel objects. Finally, in Experiment 3, we changed the response mode from a button press to a more explicit movement made with a “manipulandum”. Based on neuropsychological findings, we predicted that when action responses were made to pictures of familiar or novel objects, relative to words, there would be less activation in semantic regions but greater activation in visual, motor, and perhaps parietal cortices. We found that, action relative to screen-size decisions on both pictures and words activated the left hemisphere temporo-frontal semantic system with activation in the left posterior middle temporal cortex specific to action retrieval (Experiment 1). In addition, action retrieval elicited more activation for (1) words than pictures in areas associated with semantics; and (2) novel objects than words or familiar objects in areas associated with pre-semantic object processing. These results are discussed in the context of semantic and visual routes to action retrieval.     

Terror management and adults' attachment to their parents: the safe haven remains

Six studies examined the role of young adults' parental attachment in terror management. Studies 1-3 revealed that activating thoughts of one's parent in response to mortality salience (MS) reduced death-thought accessibility and worldview defense and increased feelings of self-worth. Studies 4-5 demonstrated that MS led to greater ease of recalling positive maternal interactions and greater difficulty recalling negative interactions, and increased attraction to a stranger who was described as being similar to one's parent. If reliance on parents for terror management purposes reflects the operation of attachment mechanisms, then such effects should vary on the basis of an individual's attachment style. Study 6 demonstrated that, after MS, insecure individuals were more likely to rely on relationships with their parents, whereas secure individuals were more likely to rely on relationships with romantic partners.     

Influence of Church Attendance and Spirituality in a Randomized Controlled Trial to Increase Mammography Use Among a Low-Income, Tri-Racial, Rural Community

Background The influence of church attendance and spirituality on mammography use was studied among Native American, White, and African American women living in a rural county. Methods A randomized trial was conducted to increase mammography use. Women (n = 851) were randomly assigned to receive either an educational program delivered by a lay health advisor or a physician letter and brochure about cervical cancer screening (control group). Church attendance and spirituality were measured at baseline and mammography use was evaluated 12 months after enrollment using medical record review. Results Almost two-thirds of the women reported that they attended church at least once a week, and less than 4% were classified as having low spirituality. Church attendance (P = 0.299) or spirituality (P = 0.401) did not have a significant impact on mammography use. Conclusions Church attendance and spirituality did not impact mammography use.     

Supporting Japanese Mothers of Children with ADHD: Cultural Adaptation of the New Forest Parent Training Programme

International practice guidelines recommend medication and behavioral intervention as evidenced‐based treatments for attention deficit hyperactivity disorder (ADHD). Currently in Japan, the availability of non‐pharmacological interventions for ADHD is limited. We report the results of a pilot and a proof‐of‐concept study for a new behavioral intervention for Japanese mothers of children with ADHD. The pilot study delivered a standard six‐session behavioral intervention and two parent‐support sessions. Participants approved the group format and requested additional support to change parenting practices and behavioral strategies targeting ADHD symptoms. For the proof‐of‐concept study, the intervention was revised to include five sessions of pre‐intervention support followed by six sessions of the New Forest Parent Training Programme (NFPP), an evidence‐based intervention for ADHD. The revised intervention, NFPP‐Japan, was associated with reductions in the mothers’ reports of children's ADHD symptoms and aggression, more effective parenting practices, and reduced parenting stress. The pilot and proof‐of‐concept studies indicate that it is possible to successfully modify Western behavioral interventions for Japanese mothers and to justify a randomized controlled trial evaluation of the NFPP‐Japan, which is currently underway.     

Polyamory: Experiences of Power from Without,from Within,and in Between

This article highlights the ways in which cultural, relational, and therapeutic power can affect polyamorous relationships and the therapeutic process. In therapy, focusing on the power narratives that polyamorous partners might experience can aid in challenging mononormativity while creating space for a variety of relational orientations. Power processes are presented as occurring on three levels: social discourse (without), relational meaning-making (within), and therapeutic practice (in between). A case study is used to evaluate these processes and implications are provided for clinicians working with polyamorous families.     

Interpretation of Ambiguity in Children: A Prospective Study of Associations With Anxiety and Parental Interpretations

Interpretation of ambiguity is consistently associated with anxiety in children, however, the temporal relationship between interpretation and anxiety remains unclear as do the developmental origins of interpretative biases. This study set out to test a model of the development of interpretative biases in a prospective study of 110 children aged 5–9 years of age. Children and their parents were assessed three times, annually, on measures of anxiety and interpretation of ambiguous scenarios (including, for parents, both their own interpretations and their expectations regarding their child). Three models were constructed to assess associations between parent and child anxiety and threat and distress cognitions and expectancies. The three models were all a reasonable fit of the data, and supported conclusions that: (i) children’s threat and distress cognitions were stable over time and were significantly associated with anxiety, (ii) parents’ threat and distress cognitions and expectancies significantly predicted child threat cognitions at some time points, and (iii) parental anxiety significantly predicted parents cognitions, which predicted parental expectancies at some time points. Parental expectancies were also significantly predicted by child cognitions. The findings varied depending on assessment time point and whether threat or distress cognitions were being considered. The findings support the notion that child and parent cognitive processes, in particular parental expectations, may be a useful target in the treatment or prevention of anxiety disorders in children.     

The interactive account of ventral occipitotemporal contributions to reading

The ventral occipitotemporal cortex (vOT) is involved in the perception of visually presented objects and written words. The Interactive Account of vOT function is based on the premise that perception involves the synthesis of bottom-up sensory input with top-down predictions that are generated automatically from prior experience. We propose that vOT integrates visuospatial features abstracted from sensory inputs with higher level associations such as speech sounds, actions and meanings. In this context, specialization for orthography emerges from regional interactions without assuming that vOT is selectively tuned to orthographic features. We discuss how the Interactive Account explains left vOT responses during normal reading and developmental dyslexia; and how it accounts for the behavioural consequences of left vOT damage.     

Are math readiness and personality predictive of first-year retention in engineering?

On the basis of J. G. Borkowski, L. K. Chan, and N. Muthukrishna's model of academic success (2000), the present authors hypothesized that freshman retention in an engineering program would be related to not only basic aptitude but also affective factors. Participants were 129 college freshmen with engineering as their stated major. Aptitude was measured by SAT verbal and math scores, high school grade-point average (GPA), and an assessment of calculus readiness. Affective factors were assessed by the NEO-Five Factor Inventory (FFI; P. I. Costa & R. R. McCrae, 2007), and the Nowicki-Duke Locus of Control (LOC) scale (S. Nowicki & M. Duke, 1974). A binary logistic regression analysis found that calculus readiness and high school GPA were predictive of retention. Scores on the Neuroticism and Openness subscales from the NEO-FFI and LOC were correlated with retention status, but Openness was the only affective factor with a significant unique effect in the binary logistic regression. Results of the study lend modest support to Borkowski's model.     

Measuring Religiousness Among Older African Americans: Exploring Race-of-Interviewer Effects

In recent years a number of studies have explored possible sources of nonrandom error and response bias in survey data on religion. Building on a longstanding body of work in the social sciences, we examine a neglected issue in this domain: the potential for race-of-interviewer effects, specifically in African Americans’ self-reports of various dimensions of religiousness. After outlining two competing perspectives on this issue—which we term racial deference and racial solidarity—we test relevant hypotheses using data from the African American oversample of a nationwide study of older adults. Results indicate that older blacks tend to report higher levels of non-organizational religious practices and subjective religiousness when interviewed by whites. A number of implications and promising directions for future research are discussed.     

Prospective information for pass decisional behavior in rugby union

Decision-making requires the perception of relevant information variables that emerge from the player–environment interaction. The purpose of the present article is to empirically assess whether players’ decisional behavior about which type of pass to make is influenced by the spatio-temporal variable tau. Time series positional data of rugby players were analyzed from video footage taken in real match scenarios. The tau of the distance motion gap between attacker and defender was calculated, along with the duration of the next pass. Results revealed that the initial tau value predicted 64% of the variance found in pass duration. A qualitative distinction of tau dynamics between two periods of the approach between the attacker and the defender was also observed. We argue that the time-to-contact between the attacker and the defender may yield information about future pass possibilities. Additionally, the informational fields constraining attacker–defender interaction may be viewed as a convergent channeling of possibilities towards a single pass solution.
