Application of the Copenhagen Soccer Test in high-level women players – locomotor activities,physiological response and sprint performance

We evaluated the physiological response, sprint performance and technical ability in various phases of the Copenhagen Soccer Test for Women (CSTw) and investigated whether the locomotor activities of the CSTw were comparable to competitive match-play (CM). Physiological measurements and physical/technical assessments were performed during CSTw for eleven Norwegian high-level women soccer players. The activity pattern during CSTw and CM was monitored using the ZXY tracking system. No differences were observed between CSTw and CM with regards to total distance covered (10093 ± 94 and 9674 ± 191 m), high intensity running (1278 ± 67 and 1193 ± 115 m) or sprinting (422 ± 55 and 372 ± 46 m) (p > .05). During CSTw, average HR was 85 ± 2%HRmax with 35 ± 2% playing time >90%HRmax. Blood lactate increased (p < .05) from 1.4 ± 0.3 mM at rest to an average of 4.7 ± 0.5 mM during CSTw, with no changes during the test. Blood glucose was 5.4 ± 0.3 mM at rest and remained unaltered during CSTw. Sprint performance (2 × 20 m) decreased (p < .05) by 3% during CSTw (8.19 ± 0.06–8.47 ± 0.10 s). In conclusion, the locomotor activities during CSTw were comparable to that of high-level competitive match-play. The physiological demands of the CSTw were high, with no changes in heart rate, blood lactate or technical performance during the test, but a lowered sprint performance towards the end of the test.     

Doing Therapy in a Foreign Land: When the Therapist Is “Not From Here”

The psychotherapy field has been paying closer attention to how therapists’ characteristics, history, and styles affect therapeutic encounters and contribute to successful therapy outcomes. Therapists have been encouraged to increase self-awareness of their own socio-cultural dimensions to optimally connect with clients. However, the experience of therapists’ own immigration has received little attention. This article highlights the experience of immigration as important for understanding the self of the therapist, describing core experiences related to immigration for immigrant therapists in the United States. This article additionally describes how these experiences can affect immigrant therapists’ clinical encounters. Finally, recommendations are provided for immigrant therapists, clinical supervisors, and training programs.     

Developmental dissociation of visual dorsal stream parvo and magnocellular representations and the functional impact of negative retinotopic BOLD responses

Localized neurodevelopmental defects provide an opportunity to study structure–function correlations in the human nervous system. This unique multimodal case report of epileptogenic dysplasia in the visual cortex allowed exploring visual function across distinct pathways in retinotopic regions and the dorsal stream, in relation to fMRI retinotopic mapping and spike triggered BOLD responses.     

When voices get emotional: A corpus of nonverbal vocalizations for research on emotion processing

Nonverbal vocal expressions, such as laughter, sobbing, and screams, are an important source of emotional information in social interactions. However, the investigation of how we process these vocal cues entered the research agenda only recently. Here, we introduce a new corpus of nonverbal vocalizations, which we recorded and submitted to perceptual and acoustic validation. It consists of 121 sounds expressing four positive emotions (achievement/triumph, amusement, sensual pleasure, and relief) and four negative ones (anger, disgust, fear, and sadness), produced by two female and two male speakers. For perceptual validation, a forced choice task was used (n = 20), and ratings were collected for the eight emotions, valence, arousal, and authenticity (n = 20). We provide these data, detailed for each vocalization, for use by the research community. High recognition accuracy was found for all emotions (86 %, on average), and the sounds were reliably rated as communicating the intended expressions. The vocalizations were measured for acoustic cues related to temporal aspects, intensity, fundamental frequency (f0), and voice quality. These cues alone provide sufficient information to discriminate between emotion categories, as indicated by statistical classification procedures; they are also predictors of listeners’ emotion ratings, as indicated by multiple regression analyses. This set of stimuli seems a valuable addition to currently available expression corpora for research on emotion processing. It is suitable for behavioral and neuroscience research and might as well be used in clinical settings for the assessment of neurological and psychiatric patients. The corpus can be downloaded from Supplementary Materials.     

Acquired Procedural Dyscalculia Associated to a Left Parietal Lesion in a Child

We report the case of an 11-year-old boy who developed an anarithmetia in association with a left temporo-parietal tumor. His oral and written language were normal as well as his ability to judge magnitudes, process numbers, read operation signs and retrieve number facts. He had a specific difficulty in performing the procedures of subtraction, especially when it involved borrowing. These skills had been mastered before the present illness. This case shows that the components of calculation can be dissociated by brain lesions sustained during childhood, while arithmetic abilities are being acquired, thus reinforcing findings from developmental dyscalculias, that suggest a modular organisation of those skills during development.     

Defect analysis of Fe3(Al1– x Si x ) alloys by positron-lifetime spectroscopy

The recovery behaviour of vacancy-type defects created at 1000°C in Fe₃(Al_{1– x} Si _x ) alloys has been investigated by positron-lifetime measurements in samples cooled to room temperature by water quenching, air quenching and furnace cooling. In addition, a set of samples was aged for one week at 520°C. After water quenching, measurements reveal a high concentration of thermal vacancies, and from the decrease of the average positron lifetime it is inferred that vacancy recovery is strongly composition-dependent. Greater decreases of the positron lifetime were found for Si-rich samples, suggesting diffusion enhancement as the Si concentration increases. For the Fe₃Al alloy, the retained vacancy concentration depends strongly on the cooling rate. This is related to atomic ordering and a rebuilding of the D0₃ structure.     

La adquisición del lenguaje: un análisis interaccional

Resumen

El principal objetivo de esta investigación fue analizar functionalmente las interacciones verbales niño-adulto, en seis sujetos, de edades comprendidas entre los 18 y los 30 meses, y sus familias, observados en ambiente natural. Un segundo objetivo fue definir y poner a prueba un sistema de Categorías funcionales para el análisis del lenguaje infantil. También se realizó un estudio del lenguaje adulto («input parental») en cuanto a una pluralidad de características, incluyendo las similitudes y diferencias entre el lenguaje de los padres y las madres.

Los resultados ponen de relieve que el lenguaje de los niños, a pesar de las limitaciones formales de estas primeras etapas, es altamente funcional e interaccional. También se ha puesto de manifiesto que el lenguaje que el adulto dirige al niño reviste unas características (en cuanto a claridad, corrección, simplicidad, etc.) en sí mismo facilitadoras de los procesos de transmisión-adquisición del lenguaje. Al mismo tiempo se ha evidenciado la existencia de estrategias educativas no intencionales en las interacciones verbales niño-adulto. Estas estrategias poseen cierto valor explicativo respecto a los procesos de desarrollo del lenguaje.

Los niños del estudio y sus familias eran catalano-parlantes, por tanto este trabajo es asimismo un estudio longitudinal sobre la adquisición del catalán como primera lengua.     

Reading strategies and prior knowledge in learning from hypertext

In two experiments, we identified two main strategies followed by hypertext readers in selecting their reading orders. The first consisted in selecting the text semantically related to the previously read section (coherence strategy), and the second in choosing the most interesting text, delaying reading of less interesting sections (interest strategy). Comprehension data revealed that these strategies affected learning differently as a function of the reader's prior knowledge. For low-knowledge readers, the coherence strategy supported better learning of the content. This effect seems to rely on the improvement of reading order coherence induced by this strategy. By contrast, for intermediate-knowledge readers the coherence and the interest strategies benefited comprehension equally. In both cases, learning was supported through the active processing induced by these strategies. Discussion focuses on resolving inconsistencies in the literature concerning whether or not hypertext supports better comprehension than does traditional linear texts.     

Spanish adaptation of the Psychological Well-Being Scales (PWBS)

The aim of this paper is to adapt to Spanish the D. van Direndonck version of Carol Ryff's Psychological Well-Being Scales, and to analyse its consistency and factorial validity. All the scales exhibited good internal reliabilities, with Cronbach alpha's ranging from 0.83 (Self-acceptance) to 0.68 (Personal growth). However, confirmatory factor analyses didn't corroborate the six-factor model (Self-acceptance, Positive relations, Autonomy, Environmental mastery, Purpose in life, and Personal growth) with a second order factor called Psychological Well-Being . To improve the psychometric properties, a new reduced version was proposed that indeed will facilitate the application. The scales of the new version maintain and raise its internal consistency (Cronbach alpha's 0.84 to 0.70). Furthermore, the scales shown an excellent fit to the theoretical model proposed by D. van Dierendonck.     

Spontaneous recovery from forward and backward blocking

This article demonstrates and analyzes spontaneous recovery of stimulus control following both forward and backward blocking in a conditioned suppression preparation with rats. Experiment 1 found, in first-order conditioning, robust forward blocking and an attenuation of it following a retention interval. Experiment 2 showed, in sensory preconditioning, recovery of responding following both forward and backward blocking. Also, the results of this experiment indicated that response recovery to the blocked stimulus cannot be explained by an impaired status of the blocking stimulus after a retention interval. Experiment 3, also in sensory preconditioning, suggested that spontaneous recovery following both forward and backward blocking in Experiment 2 was due to impaired associative activation of the blocking stimulus' representation during testing with the blocked stimulus. Although no contemporary model of associative learning can explain these results, a modification of R. R. Miller and L. D. Matzel's (1988) comparator hypothesis is proposed to do so.
