Tactical skills and ball speed during a field simulation of penalty kick strategies in soccer

This study investigates the efficacy of intermediate penalty kickers by comparing the effect of applying an automated WiFi system on the field of play to simulate a strategy that takes account of goalkeeper action (dependent) with another for which goalkeeper strategy is irrelevant (independent). Intermediate penalty kickers (n=12) took a pretreatment test of 32 kicks in a "real-play" situation with intermediate goalkeepers (n=3). Two groups of kickers underwent 11 treatment sessions using different strategies and then were administered a posttreatment test. The variables measured were the number of goals scored, whether the direction of the shot was the same or different from the direction of the goalkeeper's move (DDG), ball speed, and the duration of the kicking movement. Data suggested the goalkeepers had a greater capacity to identify advance cues when faced with independent strategy kickers and that dependent strategy kickers achieved lower ball speeds.     

Predictors of Racial Prejudice in White American Counseling Students

This study extends the research on racial prejudice by combining previously identified predictors into 1 study to determine their relative importance in contributing to racial prejudice. Results revealed that White racial identity significantly predicted racial prejudice when demographic variables were controlled. Implications of reducing racial prejudice of White American counseling students are discussed. Este estudio extiende la investigación sobre el prejuicio racial combinando pronosticadores previamente identificados en 1 estudio para determinar su importancia relativa a contribuir al prejuicio racial. Los resultados revelaron que la identidad racial Blanca apreciablemente predijo el prejuicio racial cuando los variables demográficas son controladas. Las implicaciones para reducir el prejuicio racial de estudiantes Americano Blanco que aconsejan es discutido.     

Mood congruent Bias in Interpretation of Ambiguity Strategic Processes and Temporary Activation

Three experimentsinvestigated the tendency of high-anxiety individuals to interpretambiguous information in a threatening fashion. Priming ambiguous sentences (concerned with ego-threat, physical-threat, or non-threat events) were presented, followed by a disambiguating sentence in which a target word either confirmed or disconfirmed the consequence implied by the priming context. The sentences were presented word-by-word at a predetermined pace. Subjects read the sentences and pronounced the target word (naming task), which appeared either 500 msec or 1,250 msec after the onset of the last word (pre-target word) in the priming context. Results indicated that high-anxiety subjects named target words confirming threats faster than low-anxiety subjects, relative to non-threat words. Furthermore, this interpretative bias is: (a) strategic, rather than automatic, as it occurred with a 1,250-msec SOA, but not with a 500-msec SOA; (b) temporary, as it was found under evaluative stress conditions increasing state anxiety, butnot withnon-stress; and (c) specificto ego-threats, as it happened with ambiguous information concerning self-esteem and social evaluation, rather than with physical-threat-related information.     

Does preference rank predict substitution for the reinforcer for problem behavior? a behavioral economic analysis

Predictions made under low response requirements inherent in most preference assessments (PAs) do not guarantee the utility of stimuli in treatments. We examined whether PA rank would predict how well stimuli supported compliance for children with escape‐maintained problem behavior by examining the relation between PA rank and demand elasticity across five fixed‐ratio values. Three patterns were observed: All stimuli were selected equally across values, higher ranked stimuli were selected more at higher values, and something other than the highest ranked stimulus was selected more at higher values (i.e., mixed correspondence).     

Phonological coding in reading comprehension: The importance of individual differences

Abstract

In two experiments, texts were presented word by word at a fixed pace to subjects high or low in test anxiety, under various concurrent interference conditions: no interference, articulatory suppression, finger tapping, unattended meaningful speech, reversed (meaningless) speech and nonword (meaningless) speech. High-anxiety subjects produced overt articulation more frequently than low-anxiety subjects, especially in the speech conditions. There was an interaction between anxiety and interference on comprehension performance: Conditions thought to interfere with phonological coding (i.e. articulatory suppression and nonword speech) were detrimental to comprehension for high but not for low-anxiety subjects; in contrast, there were no differences in comprehension performance as a function of anxiety under conditions causing no (proper) phonological interference (i.e. no interference, finger tapping and reversed speech). There were mixed results in the meaningful speech condition, partly attributable to its semantic interference component. These findings reveal that the use and importance of phonological coding in reading comprehension vary with differences in test anxiety-high-anxiety subjects are vulnerable to disruptive effects on phonological coding. This suggests that high-anxiety individuals are especially likely to resort to speech-based coding during reading, and that phonological coding has a compensatory role for them.     

Age-related differences in the elderly in a spatial recognition task

ABSTRACT

Spatial memory is a cognitive ability which declines with ageing thus showing changes in some process such as the use of allocentric strategies. These age-related changes in spatial orientation suggest that this skill could be an adequate marker of cognitive decline. Many tasks used in investigation to assess spatial memory demand a participant’s active role, which involves that the navigational experience is different for everyone. In this study, the Almeria Spatial Memory Recognition Test (ASMRT), a test based on a recognition paradigm, was used to offer the same experience with the environment. The aim of this research was to determine if the ASMRT is suitable to be applied in the elderly and detect spatial memory differences as one age. The ASMRT and other neuropsychological tests were applied in a sample aged between 50and 79 years. Results revealed a decrease in the ASMRT performance by the older group. No gender differences were found. Performance in attention and visuospatial working memory tests revealed some correlations with the ASMRT performance. In conclusion, this study demonstrates that 70–79-year-old participants clearly show age-related changes in spatial memory. Thanks to its simplicity the ASMRT could be used as a screening test in medical practice.     

Resilience and the burnout-engagement model in formal caregivers of the elderly

This paper investigates the relationship between resilience and positive/negative mental aspects of psychological well-being in formal caregivers for the elderly. The sample consisted of 265 caregivers who work in different residential homes in Extremadura and Castilla y León (Spain). The instruments used included the Connor-Davidson Resilience Scale , the Maslach Burnout Inventory-General Survey and the Utrecht Work Engagement Scale. The most significant findings show that caregivers with higher levels of resilience also have higher levels of professional efficacy and job engagement (vigor, dedication and absorption) and appear to be less emotionally exhausted or cynical than caregivers with lower levels of resilience. It cannot be concluded that more resilient caregivers will not get burned out, but they develop better engagement skills. As they strengthen these personal attributes, they become less vulnerable to burnout.     

Validation of semantic and pragmatic modules of the Criterial and Objective Language Battery (BLOC) in Chilean children

The aim of this work was to analyse the psychometric properties of the semantics and pragmatics modules of the Objective and Criterial Language Battery (BLOC). For the semantics module (n= 259), Cronbach's alpha was 0.84; for the pragmatics module (n= 142), Cronbach's alpha was 0.91. A Categoric Principal Components Analysis (CAPCAT), produced unidimentional solutions, explaining 41.65% of the variance in the semantics module, and 41.77% in the pragmatics module. We did not find differences in performance by sex. By socio-economic status, lower status children performed worse than those of middle and higher status, but only in the semantics module. Differences by age were small, with both modules producing between 3 and 4 homogeneous groups with substantial overlap. Lack of discrimination is probably related to reduced variability due to low performance in the Chilean samples. Compared to Spain, medians in the semantics module were lower than expected (though medians in the pragmatics module were slightly higher).
