Quiet eye facilitates sensorimotor preprograming and online control of precision aiming in golf putting

An occlusion protocol was used to elucidate the respective roles of preprograming and online control during the quiet eye period of golf putting. Twenty-one novice golfers completed golf putts to 6-ft and 11-ft targets under full vision or with vision occluded on initiation of the backswing. Radial error (RE) was higher, and quiet eye was longer, when putting to the 11-ft versus 6-ft target, and in the occluded versus full vision condition. Quiet eye durations, as well as preprograming, online and dwell durations, were longer in low-RE compared to high-RE trials. The preprograming component of quiet eye was significantly longer in the occluded vision condition, whereas the online and dwell components were significantly longer in the full vision condition. These findings demonstrate an increase in preprograming when vision is occluded. However, this was not sufficient to overcome the need for online visual control during the quiet eye period. These findings suggest the quiet eye period is composed of preprograming and online control elements; however, online visual control of action is critical to performance.     

Brightness scaling of periodic tones

Brightness is an attribute often used by musicians when describing timbral characteristics. It is related to the spectral distribution of energy, as is sharpness, studied by Zwicker (Psychoacoustics: Facts and Models, 1990). In the current work, subjects adjusted the spectral slope and thus the spectral centroid (SC) of one of a pair of sounds to make it twice as bright as the other, so as to build a perceptual scale. The ratio of SC required to double brightness is a little less than 2 and decreases as the SC of the tones increases. For these tones, the ratio of brightness is statistically different from the ratio of sharpness calculated from published models.     

Implementation of a Suicide Nomenclature within Two VA Healthcare Settings

Suicide and suicide attempts are significant issues for military, Veterans Affairs (VA), and civilian healthcare systems. The lack of uniform terms related to self-directed violence (SDV) has inhibited epidemiological surveillance efforts, limited the generalizability of empirical studies of suicide and non-lethal forms of SDV, and complicated the implementation of evidence-based assessment and treatment strategies for individuals with suicidal thoughts and/or behaviors. The Department of Veterans Affairs recently adopted the Centers for Disease Control and Prevention’s (CDC) SDV Classification System (SDVCS). This paper describes an implementation study of the SDVCS in two VA Medical Centers. The Veterans Integrated Service Network (VISN) 19 Mental Illness Research, Education and Clinical Center (MIRECC) training program for the SDVCS, including the SDVCS Clinical Tool (CT), will be discussed. Although preliminary data suggest that the CT and SDVCS are generally perceived as being acceptable and useful, further work will likely be required to facilitate widespread adoption. Potential next steps in this process are presented.     

Enlightenment and individuation: syncretism,synchronicity and beyond

This paper opens with a personal introduction to the topic of syncretism within the context of a comparison of enlightenment associated with Eastern religious traditions and individuation as experienced through Jungian analysis. A brief exploration of the recent scholarly revival of interest in syncretism follows. Some close parallels with Jungian theory are highlighted, especially in the work of Timothy Light. Applications to the syncretic trends in Tang culture along the Silk Road(s) suggest deeper patterns of interconnectedness lie at the heart of these trends. A complex systems view highlights similarities between syncretic connections and non‐local aspects of synchronistic field events. The final section attempts to extend this approach to innovation in general terms through the recently articulated concept of the ‘adjacent possible’ from the writing of Stuart Kauffman. From this, the notion of a collective pre‐conscious dimension to the psyche is extrapolated. The unifying thread of acausal emergent forms provides a potential synthetic network for these phenomena.     

Accent detection and social cognition: evidence of protracted learning

How and when do children become aware that speakers have different accents? While adults readily make a variety of subtle social inferences based on speakers’ accents, findings from children are more mixed: while one line of research suggests that even infants may be acutely sensitive to accent unfamiliarity, other studies suggest that 5‐year‐olds have difficulty identifying accents as different from their own. In an attempt to resolve this paradox, the current study assesses American children's sensitivity to American vs. Dutch accents in two situations. First, in an eye‐tracked sentence processing paradigm where children have previously shown sensitivity to a salient social distinction (gender) from voice cues, 3–5‐year‐old children showed no sensitivity to accent differences. Second, in a social decision‐making task where accent sensitivity has been found in 5‐year‐olds, an age gradient appeared, suggesting that familiar accent preferences emerge slowly between 3 and 7 years. Counter to claims that accent is an early, salient signal of social group, results are more consistent with a protracted learning hypothesis that children need extended exposure to native‐language sound patterns in order to detect that an accent deviates from their own.

Differences in brain morphology and working memory capacity across childhood

Working memory (WM) skills are closely associated with learning progress in key areas such as reading and mathematics across childhood. As yet, however, little is known about how the brain systems underpinning WM develop over this critical developmental period. The current study investigated whether and how structural brain correlates of components of the working memory system change over development. Verbal and visuospatial short‐term and working memory were assessed in 153 children between 5.58 and 15.92 years, and latent components of the working memory system were derived. Fractional anisotropy and cortical thickness maps were derived from T1‐weighted and diffusion‐weighted MRI and processed using eigenanatomy decomposition. There was a greater involvement of the corpus callosum and posterior temporal white matter in younger children for performance associated with the executive part of the working memory system. For older children, this was more closely linked with the thickness of the occipitotemporal cortex. These findings suggest that increasing specialization leads to shifts in the contribution of neural substrates over childhood, moving from an early dependence on a distributed system supported by long‐range connections to later reliance on specialized local circuitry. Our findings demonstrate that despite the component factor structure being stable across childhood, the underlying brain systems supporting working memory change. Taking the age of the child into account, and not just their overall score, is likely to be critical for understanding the nature of the limitations on their working memory capacity.     

Conversation level syntax similarity metric

The syntax and semantics of human language can illuminate many individual psychological differences and important dimensions of social interaction. Accordingly, psychological and psycholinguistic research has begun incorporating sophisticated representations of semantic content to better understand the connection between word choice and psychological processes. In this work we introduce ConversAtion level Syntax SImilarity Metric (CASSIM), a novel method for calculating conversation-level syntax similarity. CASSIM estimates the syntax similarity between conversations by automatically generating syntactical representations of the sentences in conversation, estimating the structural differences between them, and calculating an optimized estimate of the conversation-level syntax similarity. After introducing and explaining this method, we report results from two method validation experiments (Study 1) and conduct a series of analyses with CASSIM to investigate syntax accommodation in social media discourse (Study 2). We run the same experiments using two well-known existing syntactic metrics, LSM and Coh-Metrix, and compare their results to CASSIM. Overall, our results indicate that CASSIM is able to reliably measure syntax similarity and to provide robust evidence of syntax accommodation within social media discourse.     

The contributions of religious practice,existential certainty,and raising grandchildren to well-being in older adults

ABSTRACT

Religious beliefs and practices are believed to foster well-being across the life course. This study examines whether religious practice, spiritual development, and existential certainty are positively linked to well-being in grandparents (N = 2,503) and whether these factors buffer grandparents from risks associated with raising grandchildren and adjusting to changing roles. Data were collected from individuals attending Protestant churches. Spiritual development and existential certainty were positively associated with well-being. We found no evidence for buffering effects of religious practice on grandparent well-being. Grandparents raising grandchildren reported more challenges in adjusting to changes in roles compared to their peers.
