The effects of video feedback on running form

Correct running form is important for injury prevention; as such, correct form promotes continued engagement in running as a long-term form of exercise. Researchers have shown video feedback to be an effective strategy to improve athletic form for a variety of sports, but it has not been evaluated in any behavior analytic research as a method for improving running form. The purpose of this study is to evaluate the effectiveness of video feedback to improve running form for regular runners. During baseline, each participant was video recorded while running without any feedback (verbal or video). During intervention, the researcher recorded the participant, then showed them the video and provided feedback on correct or incorrect form, according to a 9-step task analysis. Results show that all three participants achieved 100% correct steps on the task analysis when video feedback was used to maintain their form during follow-up.     

Strategy choice for arithmetic verification: effects of numerical surface form

Canadian university students (n=48) solved simple addition problems in a true/false verification task with equations in digit format (3+4=8) or written English format (three+four=eight). Participants reported their solution strategy (e.g. retrieval or calculation) after each trial. Reported use of calculation strategies was much greater with word (41%) than digit stimuli (26%), and this difference was exaggerated for numerically larger problems. Word-format costs on reaction time (RT) were correspondingly greater for large than for small problems, but this Format×Size RT effect was bigger for true than for false equations. The results demonstrate that surface format affects central, rather than only peripheral, stages of cognitive arithmetic.

Phenomenological Argumentative Structure

The nontechnical ability to identify or match argumentative structure seems to be an important reasoning skill. Instruments that have questions designed to measure this skill include major standardized tests for graduate school admission, for example, the United States-Canadian Law School Admission Test (LSAT), the Graduate Record Examinations (GRE), and the Graduate Management Admission Test (GMAT). Writers and reviewers of such tests need an appropriate foundation for developing such questions – they need a proper representation of phenomenological argumentative structure – for legitimacy, and because these tests affect people's lives. This paper attempts to construct an adequate and appropriate representation of such structure, that is, the logical structure that an argument is perceived to have by mature reasoners, albeit ones who are untrained in logic.     

Wisdom won from illness: The psychoanalytic grasp of human being

From its inception psychoanalysis claimed not merely to be an effective therapy for psychological suffering, but to shed light on the human condition. But what kind of insight does psychoanalysis offer? This paper locates psychoanalysis in the western philosophical tradition, arguing that psychoanalysis provides not only theoretical wisdom about the human, but practical wisdom of a peculiar kind. The human mind, through its self‐conscious understanding can be immediately and directly efficacious in shaping its own structure.     

Comparison of four short forms of the French adaptation of the Wechsler Adult Intelligence Scale – Fourth Edition (WAIS-IV)

IntroductionThe Wechsler Intelligence Scale for Adults - 4^th Edition (WAIS-IV) is widely used in France and French-speaking countries for clinical assessment and research. This scale has excellent metric qualities; there is ample evidence of the validity and reliability of its scores. However, it takes 60 to 90 min to complete the full test. That can be problematic in research where time is limited and when examining very disturbed patients. In such cases, a short form of the WAIS-IV may be useful. Unfortunately, no short form of the French version of WAIS-IV has yet been validated using the standardization sample.ObjectiveThe aim of the present study was to identify an abbreviated form of WAIS-IV with sufficient validity and reliability to replace, in some cases, the full test.MethodFour short forms were developed taking into account the fidelity and the correlation with the FIQ of the subtests included in each of form. The metric qualities the four short forms were compared using the standardization data of the French WAIS-IV. The standardization was done using the results of a sample of 876 individuals representative of the French population from 16 to 79 years 11 months.ResultsThe analyzes showed that a short form including Information, Matrices, Arithmetic and Code provides a fairly good estimate of the FIQ. The fidelity of the estimated IQ was 0.94 and its correlation with the FIQ was 0.91. However, the average of the absolute differences between the IQ calculated with this short form and the IQ calculated with the full form was 4.24 points, with a standard deviation of 3.15 points. These differences could lead to misidentification of some individuals tested with the short form.ConclusionThe proposed short form provides a sufficient approximation of the FIQ to be used in research where the collective results are more important than those of individuals. This short form, however, does not provide an IQ measure as robust as the full form. It should therefore be used with caution only when using the full form is not possible.     

Evolution of Human Civilization in Form

The essence of human civilization is the organizational forms for production, life, and other social activities. These organizational forms usually change according to historical development and pattern. According to Marx’s theory of three social forms including personal dependence, dependence on things, and free and full development of man, human civilization can be divided into three forms, namely pre-civilization, internally divided civilization, and civilization featuring free and full development of man, of which the second one can be further divided into slavery, serfdom, capitalist civilization, etc. A new form of human advancement created in modern China is a future form of civilization in concept and direction, and a realistic form of civilization in foundation and structure.     

Development of an eight-subtest short form of the WISC-IV and evaluation of its clinical utility in children with traumatic brain injury

This study evaluated the degree to which an 8-subtest short form of the Wechsler Intelligence Scale for Children—Fourth Edition would yield acceptable estimates of the long-form Full-Scale IQ index while clarifying the underlying factor structure in a sample of 100 children and adolescents with traumatic brain injury. The short-form Full-Scale IQ had sufficient (i.e., at least two thirds) nonerror covariance with its full-length counterpart. In addition, a sufficient proportion (i.e., > 80%) of these short-form estimates fell within the 90% confidence interval of the respective full-length scores. Importantly, the elimination of 2 subtests, and in particular the Picture Concepts subtest, resulted in a factor structure where each remaining subtest was fairly specifically associated with its intended scale. It is concluded that this short form can be used clinically in children with traumatic brain injury without sacrificing reliability and with more straightforward interpretability at the level of the factor index scores.
