Influence of Instruction on Velocity and Accuracy in Soccer Kicking of Experienced Soccer Players

ABSTRACT. The authors’ aim was to investigate the speed-accuracy tradeoff in soccer kicking with the dominant and nondominant foot by using different types of instructions prioritizing speed or accuracy in experienced soccer players. Ten male soccer players were randomly given 1 of the 4 instructions that differed in aspects of the kick they should emphasize and what the secondary aim would be (speed or accuracy). It was found that ball velocity was affected by instruction in the expected way: emphasis on accuracy and ball velocity reduced for both kicking feet. In addition kicking accuracy increased when emphasizing this, but only with the dominant foot indicating that Fitts’ law only was found in kicks with the dominant foot.     

Perceptual Estimates of Motor Skill Proficiency Are Constrained by the Stability of Coordination Patterns

This study demonstrated that motor skill proficiency ratings are constrained by the same order parameter dynamics that constrain action production and action perception processes. Participants produced rhythmic actions simulated by an animated stick figure of the human arm. The primary finding was that participants’ proficiency ratings covaried most with relative phase (φ) variability compared to mean relative phase. In-phase (φ = 0°) was produced with the least variability and received the highest proficiency rating, whereas the patterns φ = ±150° were attempted with the most variability and received the lowest proficiency ratings. A temporal delay in attempting to produce the animated pattern had a large impact on produced relative phase, yet had little impact on the proficiency ratings. Proprioceptive processes provide individuals information on motor skill proficiency. The lead or lag motion of the hand to forearm segment of the animated arm was identified consistently through visual processes and revealed asymmetries in the mapping of visual input to motor output. The results are consistent with concepts from the dynamic pattern theory of coordination and are discussed with regard to relative phase as an informational variable that constraints the perception-action system across many levels.     

Formative Versus Reflective Measurement: An Illustration Using Work–Family Balance

The aim of this article is to propose the formative measurement approach that can be used in various constructs of applied psychology. To illustrate this approach, the authors will (a) discuss the distinction between commonly used principal-factor (reflective) measures in comparison to the composite (formative) latent variable model, which is often applied in other disciplines such as marketing or engineering, and (b) point out the advantages and limitations of formative specifications using the example of the work–family balance (WFB) construct. Data collected from 2 large cross-sectional field studies confirm the reliability and validity of formative WFB measures as well as its predictive value regarding criteria of WFB (i.e., job satisfaction, family satisfaction, and life satisfaction). Last, the specific informational value of each formative indicator will be demonstrated and discussed in terms of practical implications for the assessment in different psychological fields.     

Mental Hygiene Counseling as a Part of Teacher Education

A test of productive thinking was taken by 265 university freshmen by mail during the summer prior to their matriculation and by 89 other freshmen, members of a subject pool, during the academic year. Although no time limits were made explicit in either case, the subject pool group reported significantly less time spent on the questionnaire. Apparently implicit time constraints differed for the two groups. Nevertheless, the relationship between ability and productive thinking was not different in the two groups.     

A Glimpse into Co-Occupations: Parent/Caregiver's Support of Young Children's Playfulness Scale

Cooperative play between parents/caregivers and children is a positive and significant contributor to the development of children’s emotional, social, and cognitive skills and may set the stage for the formation of co-occupations. This article discusses the rationale for the development of Parent/Caregiver’s Support of Young Children’s Playfulness (PSYCP), an assessment that is based on children’s play and playfulness, adult’s playfulness, and parent–child interaction. The use of the PSYCP to assess co-occupations will allow therapists to identify the specific behaviors that either hinder or support playfulness and mutual play.     

The Theory Of Social–Cultural Genetic Gene (S- c Dna)

It took a long time for humanity to know about biogenetics. And yet its role as a determinant in the living system was not proven until the twentieth century when DNA was discovered. Similarly, it took a long time for humanity to know about culture and civilization. And yet until now there is neither definite standards for differentiating them nor a definition that is commonly acceptable. By taking an evolutionary pluralism as ontology framework and the transdisciplinary research method of the systems science, we have in the new social system model discovered the central rules that govern the social–cultural heredity: Culture–Production–Civilization. The relationship between culture and civilization is exactly that of genotype and phenotype. Culture is the S-cDNA within the social system while civilization is the social phenotype. Culture is a determinant that ultimately determines the existence, stagnation, change, and evolution of the social system.     

Ideological analytics: A study of evolving world values

This study analyses ideologies in a comparative perspective. It does so by treating ideologies as normative mental systems interacting with environmental physical realities and following their evolution in the contemporary world. As a result, it exemplifies a systematic method of undertaking a diagnosis, anagnosis, and prognosis of the global ideological situation.

The study introduces a relevance tree reflecting the conceptual framework of ideological analytics. On this basis, it presents three levels of generality which contain the outline of a substantive analysis. The examples given therein illustrate the model and could serve as prototypes for more detailed studies.

Finally, the study draws the main conclusions from the above generalizations by identifying the dialectical process of ideological dynamics. This process together with the non‐linear development of social systems produce the macrohistorical cycles of world evolution. Thus, the proposed hypothesis of dialectichaos can contribute to a better understanding oïideosocial change.     

The empathizing–systemizing (E–S) model of autism and psychoanalytic theories of truth,play and symbolization

Little psychoanalytic material or theory features today in psychological work on autism and autistic traits and vice versa. Baron-Cohen's (2003) empathizing–systemizing (E–S) model of the autism spectrum posits two main clusters of autistic features: those surrounding impaired empathy, and those surrounding heightened systemizing behaviours. (Baron-Cohen, 2009) speculates that the common root of these two clusters is the individual's concept of truth. Psychoanalysis has addressed the related issue of internal and external reality since (Freud, 1897) differentiated ‘psychic’ from ‘historical’ truths. This could be of interest to those espousing the E–S model from a cognitive paradigm, as a ‘truth’-oriented cognitive style in autism may develop interdependently with the individual's experience of internal and external realities. Psychoanalysis has developed further ideas of relevance to the E–S model surrounding play and symbolization, the latter being an often-overlooked aspect of Wing and Gould's (1979) triad of autistic features. Seen from a psychodynamic perspective, the E–S model might provide a means to increase therapists' awareness of milder autistic traits amongst service users and analysands. Equally, it could offer a tool to structure empirical research into psychodynamic therapy with autism spectrum conditions.
