Performance of basketball players and nonplayers was compared on a task requiring the recall of slides of basketball games after a 4-second view of each slide. All slides viewed depicted basketball games; one half of the slides contained structured game information (slide represented an offensive play in progress) and the other half of the slides showed unstructured game information (slide represented a turnover or rebound). As has been found for skilled chess, bridge, and Go players, basketball players were superior to nonplayers in recall for structured slides only. Furthermore, players were superior to nonplayers in a recognition task for both structured and unstructured slides, showing that players' superiority in the experimental tasks is a function of encoding information to a deeper level than nonplayers.

Although the visual modality often dominates the auditory one, one exception occurs in the presence of tempo discrepancies between the two perceptual systems: variations in auditory rate typically have a greater influence on perceived visual rate than vice versa. This phenomenon, termed “auditory driving,” is investigated here through certain techniques used in cinematic art. Experiments 1 and 2 relied on montages (slideshows) of still photos accompanied by musical selections in which the perceived rate of one modality was assessed through a recognition task while the rate of the other modality was systematically varied. A similar methodological strategy was used in Experiments 3 and 4 in which film excerpts of various moving objects were accompanied by the sounds they typically produce. In both cases, auditory dominance was observed, which has implications at both a theoretical and applied level.

According to some literature data, during voluntary long-term breath holding (BH), the heart rate (HR) increases, and according to others, it decreases.Objective: to determine the psychophysiological parameters that cause a change in HR during BH in athletes with different resistance to respiratory hypoxia.Materials and methods: HR at BH was studied in 14 beginner athletes, 15 basketball players and 12 swimmers-divers. Duration of BH was recorded. The HR was recorded on a heart rate monitor. After recording an electrocardiogram, the standard deviation of the duration of cardiac cycles was calculated. The arterial oxygen saturation was measured with a pulse oximeter. The statistically significant values of the correlation coefficient (r) were ≥0.33 with p < 0.05.Results: it was found that out of 41 sportsmen, HR increased by more than 5 % in 4, changed insignificantly in 7 and decreased by less than 5 % in 30. Beginner athletes had tachycardia, and BH was quickly interrupted by an imperative inhalation. The saturation of arterial blood with oxygen did not change and did not affect the change in HR. The decrease in heart rate in swimmers-divers in comparison with the other two groups of people examined was statistically significant (p < 0.05). The duration of BH had a direct correlation (r = 0.5) with bradycardia in these people. The duration of BH caused (r = 0.8) hypoxia, the value of which also directly influenced (r = 0.38) the severity of bradycardia. In addition, the decrease in HR depended on high HR (r = 0.36) and low HR variability (r = 0.38) before BH.Conclusion: tachycardia occurs in beginner athletes who experience discomfort with BH. Bradycardia occurs in sportsmen with a long-term BH setting without discomfort. Sympathicotonia in the prelaunch state predetermines the severity of bradycardia in BH. The duration of BH and the resulting hypoxia provide the occurrence of bradycardia.

The effects of cognate synonymy in L2 word learning are explored. Participants learned the names of well-known concrete concepts in a new fictional language following a picture-word association paradigm. Half of the concepts (set A) had two possible translations in the new language (i.e., both words were synonyms): one was a cognate in participants’ L1 and the other one was not. The other half of the concepts (set B) had only one possible translation in the new language, a non-cognate word. After learning the new words, participants’ memory was tested in a picture-word matching task and a translation recognition task. In line with previous findings, our results clearly indicate that cognates are much easier to learn, as we found that the cognate translation was remembered much better than both its non-cognate synonym and the non-cognate from set B. Our results also seem to suggest that non-cognates without cognate synonyms (set B) are better learned than non-cognates with cognate synonyms (set A). This suggests that, at early stages of L2 acquisition, learning a cognate would produce a poorer acquisition of its non-cognate synonym, as compared to a solely learned non-cognate. These results are discussed in the light of different theories and models of bilingual mental lexicon.

Abstract The ability to describe routes was assessed in participants with intellectual disability (ID) and participants without ID matched on chronological age (CA) or on mental age (MA). In two experiments, participants learned a route through a virtual environment until they reached a learning criterion. They were then asked to externalize their spatial knowledge in a verbal description task, a landmark recognition task, or a map completion task. Results revealed that participants with ID mainly described the route as a succession of actions (“turn left”), and participants in the CA group prescribed actions referring to a landmark (“turn left at the swing”). Yet, results from the other tasks showed that people with ID had good landmark knowledge of the environment.

Purpose:The current study aimed to gain insight into the physiological profile of elite basketball players in Belgium in relation to their position on the field.Methods:The group consisted of 144 players, divided into 5 groups according to position (point guards [PGs], shooting guards [SGs], small forwards [SFs], power forwards [PFs], and centers [Cs]). The anthropometrics were measured and the subjects underwent fitness tests (incremental running test, 10-m sprint, 5 ×-10 m, squat and countermovement jump, isokinetic test) to obtain insight into endurance, speed, agility, and power. The parameters of these tests were compared among the different positions by means of 1-way variance analysis (MANOVA). Tukey post hoc tests were performed in case of a significant MANOVA.Results:It was observed that Cs were taller and heavier and had a higher percentage body fat than PGs and SGs. For the anaerobic sprint test Cs were slower than the other positions. For the 5 × 10-m the PGs and SGs were faster than SFs and PFs. For the jump test Cs displayed a significantly lower absolute performance than the other positions. PGs and SGs had a higher VO2peak and speed at the anaerobic threshold than PFs and Cs. The isokinetic strength test showed that the quadriceps muscle group of Cs could exert a higher torque during knee extension than the other positions.Conclusions:The current study showed that the physiological profile of elite players in the Belgian first division differs by player position. More specifically, guards were characterized by high endurance, speed, and agility, whereas centers and power forwards had higher muscle strength than the other positions.

The purpose of this study was to determine the effectiveness of a basketball target rim on free-throw and field-goal shooting accuracy. The target rims employed in this study were different from regular rims as the apparatus that connects the target rim to the backboard was painted a neutral color. Subjects included all of the 1984–85 Eastern Washington University men's basketball players and the other players on 10 basketball teams who played games with the Eastern Washington University men's basketball team in the 1984–85 season. Practice statistics were kept in all EWU shooting situations, drills as well as scrimmages. Individual game statistics of the entire basketball game were made for the 10 games in which the target rims were used. A random selection of combined free-throw and field-goal shooting accuracy taken during the practice sessions showed that shooting percentage on the target rim was noticeably higher than the shooting percentage on the regular rim. The shooting accuracy of the EWU team and the visiting teams during game competition showed that accuracy of field-goal shooting on the target rim was significantly better than on the regular rim but not for free-throw accuracy. The target rim may improve shooting accuracy and influence total scoring in basketball.

Studies have suggested that visually presented words are obligatorily decomposed into constituents that could be mapped to language representations. The present study aims to elucidate how orthographic processing of one constituent affects the other and vice versa during a word recognition task. Chinese orthographic system has characters representing syllables and meanings instead of suffixation roles, and the majority of Chinese characters are phonograms that can be further decomposed into phonetic radical and semantic radical. We propose that semantic radical combinability indexed by semantic radicals and the effect of phonological consistency indexed by phonetic radicals would interact with each other during the reading of Chinese phonograms. Twenty-six right-handed native Chinese speakers were recruited to the study. Participants were presented with phonograms divided into four conditions following their semantic radical combinability (large vs. small) and phonological consistency (high vs. low). EEG signals were recorded throughout the covert naming task. Our results show that there is an interaction effect between phonological consistency and semantic radical combinability on the right hemisphere N170 activity while reading phonograms. Semantic radical combinability influenced the right hemisphere N170 during the process of low-consistency character reading but not high-consistency character reading. On the other hand, the left hemisphere N170 revealed a more significant activity during reading high-consistency characters and was not affected by radical combinability. In addition, while low-consistency characters revealed a larger P200 than high-consistency characters, the semantic radical combinability effect on P200 was only significant when participants were reading high-consistency characters but not low-consistency characters. These results provide new information about how ERPs are involved in word recognition within the context of interaction among orthographic and phonological dimensions.

AbstractBilinguals may be better than monolinguals at word learning due to their increased experience with language learning. In addition, bilinguals that have languages that are orthotactically different could be more used to dissimilar orthotactic patterns. The current study examines how bilinguals with languages that are orthotactically similar and dissimilar and monolinguals learn novel words that violate or respect the orthotactic legality of the languages they know and how this learning may be affected by the similarity between the bilinguals’ two languages. In Experiment 1, three groups of children were tested: monolinguals, Spanish-Basque bilinguals (dissimilar orthotactic languages), and Spanish-Catalan bilinguals (similar orthotactic languages). After an initial word learning phase, they were tested in a recall task and a recognition task. Results showed that Spanish-Basque bilingual children performed differently than the other two groups. While Spanish monolinguals and Spanish-Catalan bilinguals recognized illegal words worse than legal words, Spanish-Basque bilinguals showed equal performance in learning illegal and legal patterns. A replication study conducted with two new groups of Spanish-Basque children (one group with high Basque proficiency and one group with a lower proficiency) indicated that the effects were not driven by the proficiency in the second language since a similar performance on legal and illegal patterns was observed in both groups. In Experiment 2, two groups of adults, monolinguals and Spanish-Basque bilinguals, were tested with the same task used in Experiment 1. The effect seen in children seems to be absent in adults. Spanish-Basque bilingual adults showed better overall learning performance than monolinguals, irrespective of the illegality of the items. Differences between groups could be due to the effect of having acquired literacy and linguistic competence.

A két- és többnyelvuek információtárolása és  feldolgozása vitatott téma: egyes kutatók szerint ez olyan kognitív alrendszerek segítségével történik, amelyek tartalmazzák az emlékezeti képzeteket is és beszélt nyelveikkel állnak kapcsolatban, viszont funkcionálisan függetlenek egymástól (a függetlenség hipotézise); egy másik modell szerint (az egymástól való függés hipotézise) a különálló lingvisztikai rendszerek funkcionálisan kötodnek egy olyan közös fogalmi rendszerhez, ami egyben a megosztott memóriatároló is. Kísérletem célja az volt, hogy egyetlen vizsgálatban, különbözo bevésési stratégiákat és elohívási feladatokat alkalmazva olyan teljesítménymintákat mérjek fel, amelyeket egyik vagy másik modell alátámasztására szoktak felhozni; ezenkívül a fejlodési hipotézist is vizsgálom.Magyar–román–angol háromnyelvuek vettek részt a vizsgálatban két csoportba osztva. Hipotézisem szerint az angolt nehézkesebben beszélok teljesítménye egy adatvezérlésu szókiegészítési feladatnál a függetlenégi hipotézist kell hogy alátámassza, azonban eredményeim azt mutatták, hogy az adat vezérlésu és fogalmi vezérlésu feldolgozás itt együtt jelentkezik; a szabad felidézési feladat ered ményei a nyelvtol való függetlenség hipotézisét támasztották alá, a felismerési feladat eredményei pedig szintén a két típusú feldolgozás kombinációját mutatták. Az angolt folyékonyabban beszélo alanyok esetében nem találtam szignifikáns különbségeket a különbözo bevésési stratégiák között, ami újabb bizonyítékot jelent Kroll és Stewart (1994) modellje mellett. A nehézkesebben beszélo háromnyelvuek tehát a lexikális- és fogalmi közvetítés kombinációját mutatták, és csak a gyakorlott beszélokre jellemzo a tiszta fogalmi közvetítés. Általános következtetésem az, hogy a leghasznosabb kutatási paradigma egy olyan transzfer-központú szemlélet lenne, amelyben a megorzési próbákon való teljesítmény olyan mértékben javul, amilyen mértékben a teszt által megkövetelt eljárások megismétlik a bevésési eljárásokat.Bilinguals’ information-representation and -processing is a controversial theme among psycholinguists: According to some researchers bilinguals have cognitive subsystems linked to their known languages, which include the memory stores, as well, but they are functionally independent from each other (independence position). On the other hand, the interdependence position maintain that bilinguals represent words in a supralinguistic code, possibly based on the meanings of the words, that is independent of the language in which the words occurred. According to the developmental hypothesis second language learners start only with lexical associations, but gradually develop direct links between the second language lexicon and concepts.The aims of my study were: 1) to measure performance patterns, which are usually taken to reflect the one or the other model, in one experiment, using different retrieval tasks under identical encoding conditions; 2) to examine the developmental hypothesis by using less fluent and more fluent trilinguals.        The subjects of my study were Hungarian–Romanian–English trilinguals, divided into two groups. According to my hypothesis, in the case of the less fluently speakers of English, a mostly data-driven task such as word fragment completion would depend on the matching of language at study and test, thus supporting the independence hypothesis. However, my results showed that in the case of this task both the data-driven and conceptually-driven processing is present: not only the language of study was important, but the increasing elaborate processing during study, as well. The results of the free recall task, as predicted, revealed evidence for interdependence effects. Finally, the recognition task showed again the combination of the two kind of processing: data-driven and conceptually-driven processing. The more fluent subjects, in turn, could face all the conditions and all the tasks almost equally well, suggesting that they mediate their languages entirely conceptually. In sum, we can tell that in the mind of the multilingual words are organised on the basis of meaning, not language. At very early stage of language acquisition, however, language specific cues intrude, even when subjects are concentrating upon meaning.My general conclusion is that the most useful research paradigm would be a transfer appropriate approach, according to which the performance on the retention tasks benefit to the extent to which procedures demanded by the task repeat those employed during encoding.

The purpose of this paper is to investigate how the use of a linguistic form (lexical reduplication) can communicate affective contents. Lexical reduplication, understood as the intentional repetition of a word, is defined as a pattern XX used to convey, on the one hand, a content which differs from the “basic” meaning of X by involving, for instance, intensification, narrowing, or expansion, and, on the other hand, an affective content that results from the evaluation of the state of affairs at hand. To test reduplication as well as the derivation of affective contents linked to its use, I have relied on a recognition task: after hearing a short story, participants were asked if the items presented on the screen occurred in the story or not. The results obtained suggest that the formal pattern of reduplication plays the role of a trigger.
