Evaluating video modeling and video modeling with video feedback to enhance the performance of competitive dancers

This study evaluated the use of video modeling and video modeling plus video feedback to enhance four adolescents' performance of a dance movement. Intervention was evaluated in a multiple baseline across participants design. This study found that video modeling enhanced performance from baseline, but the addition of video feedback produced further increases. For one participant, improvement was dependent on the perspective of the video model. Implications of these findings and suggestions for future research are discussed.     

Effects of word frequency on individual-item and serial order retention: Tests of the order-encoding view

The order-encoding view of the word frequency effect proposes that low-frequency (LF) items attract more attention to the encoding of individual-item information than do high-frequency (HF) items, but at the expense of order encoding (DeLosh & McDaniel, 1996). When combined with the assumption that free recall of unrelated words is organized according to their original order of presentation, this view explains the finding that HF words are better recalled than LF words in pure lists but that, in mixed lists, recall is better for LF words. The present study confirmed that in mixed lists, order memory becomes equivalent for HF and LF words and that the predicted pattern of order memory and recall holds fo r incidental order-encoding conditions, for longerlists than those used inprevious experiments, and for lists with minimal interitem associativity. Moreover, recall from HF lists declined, but recall from LF lists improved, in related-word lists, relative to unrelated-word lists, reversing the usual pure-list free recall advantage for HF words. These results were uniquely predicted by the order-encoding account and favor this view over accessibility, interitem association, and cuing effectiveness explanations of the word frequency effect.     

George Floyd’s death and COVID-19: inflection points in the Anthropocene Era?

George Floyd’s death, the COVID-19 pandemic and climate change are on a continuum from the immediate shock of viewing a video-recorded murder, to millions dying worldwide from disease, to deaths related to climate change accumulating over a millennium. They participate in the powerful archetypes of death and inequality. ‘Increase’, Hexagram 42 in the I Ching, archetypically addresses inequalities at all levels – racial, economic, political and the profound imbalance between humans and the environment. Floyd’s death highlights the consequences of systemic racism and income inequalities. The pandemic as ‘nature’s revenge’ hits minority populations harder due to underlying health conditions resulting from poverty and greater exposure to the virus in the workplace. President Trump as Trickster showed Americans their shadow and his response to the pandemic amplified its severity. The pandemic has shocked our social, political and economic systems and paused our species rush into environmental disasters at many levels. The disruptions present opportunities for reflection, experimentation and developing new systems as old forms are challenged. The ecological dimensions of Jung’s concepts emphasize interconnectedness at all levels and the paradigm shift he called a ‘new age’ provides a framework for altering the course of the Anthropocene Era.     

Examining dimensions of vulnerability among children in Uganda

Insufficient data on the nature and extent of children's vulnerability in Uganda has challenged government and donors in priority setting, resource allocation and developing effective approaches to improve well-being. We conducted a population-based survey among a nationally representative sample of 2551 households, covering a total of 7946 children. We engaged national stakeholders in a priority-setting exercise to develop a scoring system to assess dimensions of children's vulnerability. The exercise identified individual and household characteristics to assess vulnerability--many of which had not been measured previously--to which numerical weights representing vulnerability level were assigned. Highly weighted characteristics included maternal death, disability, child labour and pregnancy before age 17. Psychosocial elements included living apart from siblings, having nobody to talk to and never visiting a living parent. According to this approach, an estimated 51.1% of children in Uganda (weighted for national population distribution) are considered critically or moderately vulnerable. It is to these children, equivalent to a national total of 8.7 million, that support services should be prioritised. However, survey data suggest that the most critically vulnerable children are under-represented in several types of support services. This pioneering, participatory methodology provides a rudimentary, but valuable, first step towards quantifying the vulnerability of children in Uganda and assessing their resource needs. It has been used by the Government of Uganda to determine subcategories of vulnerability for resource allocation. A major advantage is that it uses local contextual knowledge of child vulnerability rather than generic criteria applied in international surveys. Further analytical work is required to validate the methodology, link it to child well-being outcomes and devise a practical tool for service providers to refine programme targeting. The approach may be useful to national, regional or local service providers seeking an overview of their client base to monitor and improve programme-targeting efforts.     

Evidence That Episodic Memory Impairment During Tobacco Abstinence Is Independent of Attentional Mechanisms

Previous studies have demonstrated reductions in episodic memory during nicotine withdrawal. However, these studies have been unable to dissociate memory reductions from losses in attention associated with tobacco abstinence. In the present study, the authors sought to determine whether episodic memory reduction is a primary effect of nicotine withdrawal during tobacco abstinence. Heavy smokers were tested when smoking normally and following 24 hrs of abstinence. Participants were tested with a recognition memory task in which items were studied under full and divided attention conditions. Forward digit span and backward digit span were also included as control measures. Withdrawal was associated with a reduction in memory performance that was independent of attention at encoding. The authors conclude that impairment of episodic memory is a primary effect of nicotine withdrawal during tobacco abstinence. Further research is required to determine if this is associated with continued use of tobacco and cessation failures.     

In Praise of Anger

Anger, as archetypal, is met with ambivalence. Buddhism considers it toxic, and Christianity holds it as a sin and as righteousness itself. Ancient Hebrew and Hindu cultures locate it in the seat of divinity. This article aims to explore and psychologically redeem anger in its everyday manifestations and in its background in the Western tradition. The Christian Bible, Ancient Greek literature, Dante, Blake, and Shakespeare are all visited. An image emerges of a force that paradoxically graces us with its benefactions as well as destroys us.     

Do monkeys think in metaphors? Representations of space and time in monkeys and humans

Research on the relationship between the representation of space and time has produced two contrasting proposals. ATOM posits that space and time are represented via a common magnitude system, suggesting a symmetrical relationship between space and time. According to metaphor theory, however, representations of time depend on representations of space asymmetrically. Previous findings in humans have supported metaphor theory. Here, we investigate the relationship between time and space in a nonverbal species, by testing whether non-human primates show space–time interactions consistent with metaphor theory or with ATOM. We tested two rhesus monkeys and 16 adult humans in a nonverbal task that assessed the influence of an irrelevant dimension (time or space) on a relevant dimension (space or time). In humans, spatial extent had a large effect on time judgments whereas time had a small effect on spatial judgments. In monkeys, both spatial and temporal manipulations showed large bi-directional effects on judgments. In contrast to humans, spatial manipulations in monkeys did not produce a larger effect on temporal judgments than the reverse. Thus, consistent with previous findings, human adults showed asymmetrical space–time interactions that were predicted by metaphor theory. In contrast, monkeys showed patterns that were more consistent with ATOM.     

Videotherapie bei postpartalen Störungen

Video recording is currently part of in- and out-patient therapy programs for parents with infants. The observation and analysis of video sequences allow the patient to gain an extraordinary insight with respect to its own experience and behaviour. Video Microanalytical Therapy (VMT) looks for the mother’s positive qualities in her relationship to the child and employs these qualities in order to support successful interactions. VMT is well-suited to the treatment of mothers with postpartal affective or psychotic disorders, because the typical cognitive distortions and reduced perception shown by these mothers can be avoided to a large extent through the use of pictures. In this study, a video microanalytical therapy concept will be presented, that was developed for the treatment of postpartally disordered mothers at the Psychiatric Centre Nordbaden in Wiesloch, Germany.     

A review of behavioral interventions to enhance sports performance

Research on applied behavior analysis and sports performance has become an increasingly popular subject. It involves using behavioral measures to assess the utility of numerous interventions to enhance athletic performance. We identified 101 studies published since the late 1960s focusing on behavioral interventions to enhance sports performance. To determine the breadth of the current research, we identified each sport and the different interventions used to improve performance. Of the studies included in this review, research has investigated 23 interventions with 21 sports. The purpose of this paper is to review the current literature regarding what procedures have been evaluated, the results of this research, some of the limitations, and future directions of behavioral research on sports performance enhancement. In doing so, this review will allow readers to easily browse the current literature by the sport or intervention of interest.
