The present paper reports findings from a longitudinal study examining the development of English as foreign language learning in a sample of 86 Italian students tested at Grade 6 (mean age 11:3) and Grade 8 (mean age 13:3) . Two measures were examined: one relating to sustained learning ( i.e., English learning attainment), and one to short period development,(i.e., change in English proficiency). Different pattern of predictors were identified among L1 reading (speed and comprehension) and mathematics skills. The main findings indicated that calculation components of mathematics skills and reading comprehension predicted English learning attainments at Grade 8, whilst L1 reading speed at Grade 6 strongly predicted changes in English learning proficiency. The theoretical and empirical implications of the results are discussed in the specificity of a learning direction from a transparent L1 to a non‐transparent L2.

The present study explored behavioral and eye-movement measures in unilateral neglect patients in response to online bisection task (unfilled gap line). Two different tasks supported the bisection performance, a pointing and a grasping strategy. It was explored whether these different strategies may influence subjects' behavioral and eye-movement measures in response to different segment features: segment length (from shorter to longer) and segment spatial dislocation (from right to left spatial location). Consistent spatial biases were found for both bisection responses, fixation count, and duration, as well as for the first fixation count in case of pointing task. An "extreme-left" gradient effect was suggested and discussed, with patients' behavioral and eye measures more impaired. On the contrary, the patients' performance overlaps with the controls' one in case a grasping task. The direct link of visual pointing and grasping strategy, respectively, with the two cortical ventral and dorsal pathways was adduced to explain our results. 相似文献

Within aquatic ecosystems, chemosensory cues provide valuable public information regarding the form and degree of risk, allowing prey to make informed behavioural decisions. Such cues, however, may vary in both relative concentration detected (i.e. ‘quantity’) and reliability of the information available (i.e. ‘quality’), leading to varying response patterns. Moreover, prey species are also known to exhibit consistent behavioural tactics towards managing risk (i.e. personality), possibly shaping their use of public information. Here, we present two experiments examining the potential interacting effects of personality and the quantity (Experiment 1) or quality (Experiment 2) of public information on the short-term predator avoidance responses of wild-caught Trinidadian guppies under semi-natural conditions. Our first experiment demonstrated that personality shaped responses to a high concentration of alarm cues (high risk), with shyer guppies exhibiting stronger antipredator responses than bolder guppies. When exposed to either low risk or stream water controls, personality had no effect on the intensity of response. Our second experiment demonstrated that personality again shaped the response to high concentrations of alarm cues (a known risk) but not to a novel chemosensory cue (tilapia odour). When exposed to the unknown novel cue, guppies exhibited a relatively high intensity antipredator response, regardless of personality. Combined, our results suggest that individual risk-taking tactics shape the use of public information in a context-dependent fashion. 相似文献

During preadolescence children start to give attention to the future, to formulate thoughts, and to wonder about what they want. They also acquire knowledge and experiment with strategies to assist them in designing their future career. Among the constructs that can now play a relevant role in life designing, the four resources of career adaptability have a prominent role. This article reports the psychometric properties of the Italian version of the Career Adapt-Abilities Scale-International Form 2.0 for a group of middle school students. Two different studies involving Italian preadolescents were conducted. The first study tests the instrument's multidimensional structure, internal consistency and discriminant validity. The second one verifies the factorial structure's across-gender invariance and the test–retest reliability. Results provide strong psychometric support for the CAAS-Italian Form with preadolescents as a valid measure for analyzing their career adaptability and for using it in career counseling and education. 相似文献

Anthropogenic noise pollution is recognized as a major global stressor of animals. While many studies have assessed the unimodal impacts of noise pollution with a focus on intraspecific acoustic communication, little is known about noise pollution on the perception of visual and chemical information. The ‘distracted prey hypothesis’ posits that processing noise interferes with processing other information in the brain. Here, we found evidence for such a cross-modal effect of noise on the antipredator behaviour of a freshwater prey fish, the fathead minnow, Pimephales promelas. In laboratory trials, exposure to noise from a motorboat caused the total absence of the classical fright reaction of minnows to conspecific alarm cues, whereas an ambient noise control had no such impact. In natural habitats, the impairment of such antipredator behaviour due to noise pollution could have major fitness consequences. We discuss how our findings translate to animal ecology and the need for future studies that target specific management decisions regarding noise pollution. 相似文献
