How does the manipulation of time pressure during soccer tasks influence physical load and mental fatigue?

This study aimed to analyze whether having more or less time to solve soccer tasks influences physical load and mental fatigue. 48 semi-professional soccer players, from teams in national leagues participated (M_age = 22.4, SD_age = 2.25). They carried out 2 sessions with 4 tasks in each session. In one session, there was more time available; in the other, there was less time available. GPS technology was used to measure physical load, and an adaptation of NASA and Visual Analog Scale to measure mental load and mental fatigue. A related-samples T-test and magnitude based on inference were used to determine the possible effect. Soccer players reported that tasks with less available time were more mentally demanding. Moreover, less available time to solve the tasks significantly increased players’ RPE and decreased their Heart Rate and external physical load. Therefore, the available time significantly affects mental and physical load and mental fatigue.     

Tai Chi exercise training enhances executive function and fluid intelligence of healthy older adults: Cross-sectional and longitudinal evidence

Executive function and fluid intelligence are two of the crucial frontal lobe functions susceptible to aging. Tai Chi as a mind-body exercise has been proposed for preventing cognitive aging. However, whether Tai Chi has similar effects on multiple components of executive functions in older adults remains underspecified. Moreover, it is not currently known whether Tai Chi exercise training improvements in lower-order executive functions are able to explain improvements in higher-order fluid intelligence. Study 1 included a cross-sectional design based on a large sample of healthy older adults (55–79 years old). Modeling results showed that experience of Tai Chi training exerted significantly positive effects on fluid intelligence, inhibition and updating after controlling for age and education. Both inhibition and updating mediated effects of Tai Chi on fluid intelligence. Study 2 carried out a 12-month Tai Chi training intervention on a novice group and an experienced group of older adults. Results indicated that only the novices exhibited significant improvements in inhibition and fluid intelligence. In addition, improvements in fluid intelligence were no longer significant after controlling for improvements in inhibition. These results shed lights on the mechanism by which mind-body training enhances intelligence.     

The efficacy of remote video-based behavioral skills training and awareness training on public speaking performance

This study evaluated the efficacy of (a) remote video-based behavioral skills training (BST) with added speech outlines on teaching public speaking behaviors and (b) remote video-based awareness training (AT) on speech-disfluency rates. A multiple-baseline design across speech behaviors was used to evaluate the training. Remote video-based BST and AT were effective at teaching public speaking behaviors and reducing speech disfluencies, respectively, for both participants. In addition, performance generalized to increased audience size. Although expert ratings of perceived public speaking effectiveness improved following BST, the ratings did not improve and some worsened following AT. Both participants reported satisfaction with video-based BST and AT. One participant reported greater comfort, confidence, overall ability, and less anxiety as a public speaker following BST. Both participants reported greater improvements in those categories following AT. Our results suggest that public speaking behaviors can be taught using remote video-based BST and speech disfluencies can be reduced using remote video-based AT.     

Working in Indigenous Contexts: Self‐Reported Experiences of Non‐Indigenous Australian Psychologists

Despite assertions in the literature that psychologists adopt culturally inappropriate strategies for working with Indigenous clients, there is little empirical evidence about this. The aim of this study was to document the self‐reported experiences of non‐Indigenous psychologists working with Indigenous clients, the factors that they felt constrain these interactions, and the clinical, assessment and communication strategies they perceived as effective in Indigenous contexts. Structured interviews were held with 23 psychologists, 18 females and five males, with age groups ranging from 20–30 to 50+. Thematic analysis of the data revealed that participants experienced contradictions between the typical Western white psychologists' ways of interacting with clients, which they had been taught and the typical ways in which relationships are structured in Indigenous communities. The results suggest that the Western model of psychological training does not work very well in Indigenous contexts, and that psychologists working in Indigenous contexts have to work out their own methods on a trial‐and‐error basis. This points to the need for more systematic cultural competence training. However, there is a lack of research into the effectiveness of psychological intervention from the viewpoints of Indigenous clients themselves.     

Guidelines for Cognitive Behavioral Training Within Doctoral Psychology Programs in the United States: Report of the Inter-Organizational Task Force on Cognitive and Behavioral Psychology Doctoral Education

The Association for Behavioral and Cognitive Therapies initiated an interorganizational task force to develop guidelines for integrated education and training in cognitive and behavioral psychology at the doctoral level in the United States. Fifteen task force members representing 16 professional associations participated in a yearlong series of conferences, and developed a consensus on optimal doctoral education and training in cognitive and behavioral psychology. The recommendations assume solid foundational training that is typical within applied psychology areas such as clinical and counseling psychology programs located in the United States. This article details the background, assumptions, and resulting recommendations specific to doctoral education and training in cognitive and behavioral psychology, including competencies expected in the areas of ethics, research, and practice.     

Delusional development in child autism at the onset of puberty: vicissitudes of psychic dimensionality between disintegration and development

Although the psychogenetic hypotheses on child autism have been superseded, psychoanalysis can still reflect on the relational exchange and its sensory aspects in concomitance with the mental development of these patients. Without making generalizations as regards the pathogenesis, but considering the specific features of each autistic child, it may be possible to achieve an integration of those islands of competence that make up these patients' limited personal heritage. Such integration may be reached through the analysis of representational, emotional and relational transformations. The first part of this article describes the case of an autistic child in treatment from the age of four on a four-times-weekly basis who, during puberty, developed severe formal thought disorders together with delusional and hallucinatory formations. The second part develops some post-Jungian theoretical contributions, such as the concept of self as nothingness and the idea of the unsaturated archetype, so as to evaluate the function of some a-priori concepts in support of the analyst's position. These concepts are considered in relation to Bion's model of transformation, and to the formulations on dimensional awareness, especially on the shift from a two-dimensionality to three-dimensionality view, as well as to the rhythm of the object's presence and absence.     

The effects of video modeling with voiceover instruction on accurate implementation of discrete-trial instruction

The present study replicates and extends previous research on the use of video modeling (VM) with voiceover instruction to train staff to implement discrete-trial instruction (DTI). After staff trainees reached the mastery criterion when teaching an adult confederate with VM, they taught a child with a developmental disability using DTI. The results showed that the staff trainees' accurate implementation of DTI remained high, and both child participants acquired new skills. These findings provide additional support that VM may be an effective method to train staff members to conduct DTI.     

TRIAL-BASED FUNCTIONAL ANALYSIS AND FUNCTIONAL COMMUNICATION TRAINING IN AN EARLY CHILDHOOD SETTING

Problem behavior is common in early childhood special education classrooms. Functional communication training (FCT; Carr & Durand, 1985 ) may reduce problem behavior but requires identification of its function. The trial‐based functional analysis (FA) is a method that can be used to identify problem behavior function in schools. We conducted trial‐based FAs and FCT with 3 children in an early childhood special education setting. All trial‐based FAs resulted in identification of behavioral functions, and subsequent FCT led to reductions in problem behavior and increases in communication.     

Evaluation of a self-instruction package for conducting stimulus preference assessments

Research suggests that inexperienced individuals cannot accurately implement stimulus preference assessments given written instructions alone. Training that includes written instructions supplemented with feedback from a professional with expertise in conducting preference assessments has proven effective; unfortunately, expert-facilitated direct training may not be widely available. In the current study, we used multiple baseline designs to evaluate the efficacy of an antecedent-only self-instructional package to train staff members to implement two methods of stimulus preference assessments. Accuracy was low when participants had access to written instructions alone. When access to enhanced written instructions was provided (i.e., technical jargon was minimized; instructions included pictures, diagrams, and step-by-step examples), inexperienced staff accurately implemented the assessments. Results are discussed in terms of opportunities to disseminate behavior-analytic technologies through self-instruction and print resources.     

A comparison of intraverbal training procedures for children with autism

We compared the effectiveness of three training procedures, echoic and tact prompting plus error correction and a cues-pause-point (CPP) procedure, for increasing intraverbals in 2 children with autism. We also measured echoic behavior that may have interfered with appropriate question answering. Results indicated that echoic prompting with error correction was most effective and the CPP procedure was least effective for increasing intraverbals and decreasing echoic behavior.
