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.     

Types of semantic category and stimulus modality in procedural learning: implications for models of semantic memory

The present work attempts to determine whether procedural learning of a semantic categorisation task is influenced by the type of semantic category of the stimuli (biological and non-biological elements). It is also an attempt to determine the effect of the stimulus presentation modality on the categorisation task. A semantic categorisation task (4 series of 40 stimuli) was administered to 256 participants (128 classifying pictures, and 128 classifying words). Biological categories were responded to faster than non-biological ones although there were no significant differences between the interaction of the category type and the stimulus presentation modality. Reaction times progressively decreased with practice. However, the initial differences disappeared when subjects were trained. The way that current models account for these investigation findings is discussed. In addition, it is suggested that there is an attentional bias in favor of biological elements, which disappears when presumably less relevant elements become more relevant as a function of the task characteristics.     

Grammatical comprehension in older adults, both normal and with cognitive impairment: a comparative study based on discriminant and multidimensional scaling techniques

Memory and language tests are usually used to differentiate healthy elderly individuals and individuals with cognitive impairment (CI). In the latter case, there are usually no tests to assess grammatical comprehension. The aim of this paper is to explore the differences in grammatical comprehension between healthy older adults and older adults with CI, identifying the sentences that best discriminate these groups, as well as the underlying dimensions that are most relevant to the individuals. Participants were 71 elderly people, divided into two groups according to their performance on the Spanish version of the Mini Mental State Exam: normal and CI. All were given a comprehension test that included 12 kinds of sentence structures. The CI group performed significantly worse than healthy elderly group. The greatest differences were observed in the sentences adjusted to canonical order in Spanish. The sentences with higher weights in the discriminant function were the ones adjusted to the one-proposition canonical order. Propositional density was the most salient dimension in both groups. Individuals with CI had difficulty assigning thematic roles to constituents, even when it could be done by following a strategy based on the linear order of the roles.     

Impact of interactivity on identification with characters in fiction

The effect of interactivity on identification with characters in audiovisual fiction was observed. 310 participants were asked to watch a film in one of these two conditions: 1) interactive (they selected the plot), and 2) non-interactive (they consumed the fiction in a conventional way). After watching the movie, they completed a questionnaire with the EDI scale of identification and empathy with characters, created by Igartua and Paez. The capacity to intervene in the configuration of the plot (interactivity) affected identification with characters. The results provide data about the psychology of media and interactivity in communication and allow us to understand the processes of empathy and identification with characters.     

Social perception of the Spanish law for young offenders

The implementation of the law 5/2000 for the regulation of Criminal Responsibility for Minors has led to a change in interventions in cases of juvenile offenders. This law promotes the educational and rehabilitative aims of the measures imposed. However, the focus of the media on the most serious cases has generated considerable alarm in society in general. The aim of this study is to determine the social perception of Law 5/2000. For this purpose, a sample of 936 people from the Autonomous Region of the Canary Islands was surveyed. The main results indicate that there is a significant lack of knowledge about the law and that people tend to think that the measures taken are not as effective as studies carried out in connection with this subject have shown. Nevertheless, the people surveyed are more in favour of educational measures than of measures that penalize. These results are discussed in connection with the importance that community factors have in dealing with juvenile delinquency, and in particular, in the power of social pressure to modify legislation, and of the community to assume responsibility for the reinsertion of juvenile offenders.     

Hardy personality, self-efficacy, and general health in nursing professionals of intensive and emergency services

In this study, the predictive power of hardy personality and generalized self-efficacy on general health perception was investigated in a sample of nursing personnel working in emergency and intensive care services. A cross-sectional retrospective design was used, and the following measurement instruments were applied: a sociodemographic and work questionnaire, Goldberg's GHQ-28 Health Questionnaire, the Baessler and Schwarzer General Self-efficacy Questionnaire, and the Hardy Personality Subscale of Moreno's Nursing Burnout Questionnaire (CDPE). The results revealed a positive and statistically significant relationship between the individual variables of generalized self-efficacy and hardy personality. A canonical correlation analysis carried out on the psychological distress symptoms with self-efficacy and hardy personality as predictor variables, led us to emphasize the relevance of the construct total hardy personality as a predictor and, consequently, as a protective factor against the onset of psychological distress symptoms in the sample of professionals studied. Lastly, the implications of the results for clinical practice are discussed.     

Acceptance of chronic pain in fibromyalgia patients: adaptation of Chronic Pain Acceptance Questionnaire (CPAQ) in a Spanish population

Acceptance of chronic pain appears as an important factor in the personal ability to restore functioning in the presence of chronic pain. The Chronic Pain Acceptance Questionnaire (CPAQ) is currently the only instrument used to assess the acceptance of pain in people who suffer chronic pain. The revised 20-item version of McCracken and cols. (2004) showed satisfactory psychometric properties. Nevertheless, the CPAQ has not been used in Spain in fibromyalgia patients. The first goal of the study is to examine the Spanish translation of the CPAQ and assess its psychometric properties in a sample of 145 subjects with a diagnosis of fibromyalgia. The second purpose was to analyze the relationships between the CPAQ and other important measures of pain adjustment. Results of exploratory factor analysis indicated that the two-factor model, in a 15-item test, provided a good fit to the data in fibromyalgia patients. Regression analyses showed strong relations with criteria variables (pain intensity, anxiety, depression, etc.) though the subscale Activity Engagement contributed more than Pain Willingness to the prediction of criteria variables.     

Use of multilevel logistic regression to identify the causes of differential item functioning

Given that a key function of tests is to serve as evaluation instruments and for decision making in the fields of psychology and education, the possibility that some of their items may show differential behaviour is a major concern for psychometricians. In recent decades, important progress has been made as regards the efficacy of techniques designed to detect this differential item functioning (DIF). However, the findings are scant when it comes to explaining its causes. The present study addresses this problem from the perspective of multilevel analysis. Starting from a case study in the area of transcultural comparisons, multilevel logistic regression is used: 1) to identify the item characteristics associated with the presence of DIF; 2) to estimate the proportion of variation in the DIF coefficients that is explained by these characteristics; and 3) to evaluate alternative explanations of the DIF by comparing the explanatory power or fit of different sequential models. The comparison of these models confirmed one of the two alternatives (familiarity with the stimulus) and rejected the other (the topic area) as being a cause of differential functioning with respect to the compared groups.     

Protective role of educational level on episodic memory aging: An event-related potential study

The aim of the present experiment was to investigate whether educational level could modulate the effect of aging on episodic memory and on the electrophysiological correlates of retrieval success. Participants were divided into four groups based on age (young vs. older) and educational level (high vs. low), with 14 participants in each group. Event-related potentials (ERP) were recorded while participants performed a word-stem cued-recall task. Age-related memory deficits were greater for the less educated individuals. Age differences in the ERP old/new effects were also modulated by the level of education. This study demonstrated that the effects of age on episodic memory and ERP correlates of retrieval success are smaller in participants with high educational levels than those with lower levels. These findings provide support for the reserve hypothesis and highlight the need to consider individual differences when studying cognitive and cerebral changes in aging.     

Methodological and practical issues regarding phenomenological subtypes of highly suggestible individuals: A response to Kumar

A hypnotic induction produces different patterns of spontaneous experiences across individuals. The magnitude and characteristics of these responses covary moderately with hypnotic suggestibility, but also differ within levels of hypnotic suggestibility. This study sought to identify discrete phenomenological profiles in response to a hypnotic induction and assess whether experiential variability among highly suggestible individuals matches the phenomenological profiles predicted by dissociative typological models of high hypnotic suggestibility. Phenomenological state scores indexed in reference to a resting epoch during hypnosis were submitted to a latent profile analysis. The profiles in the derived four-class solution differed in multiple experiential dimensions and hypnotic suggestibility. Highly suggestible individuals were distributed across two classes that exhibited response patterns suggesting an inward attention subtype and a dissociative subtype. These results provide support for dissociative typological models of high hypnotic suggestibility and indicate that highly suggestible individuals do not display a uniform response to a hypnotic induction.
