RESUMO
The study provides a comprehensive picture of the eï¬ect of subtitles on the gaze behavior of the participants while watching continuity editing and discontinuity editing style cinema. Three video clips (with English subtitles and without subtitles) of continuity editing and discontinuity editing styles were presented to participants. The video clips came from English movies and the participants were not native English speakers. Entry time, dwell time, ï¬rst ï¬xation time, scan path, and average ï¬xation duration were taken as dependent variables in this within-group study. The eye-tracking data gathered were subjected to repeated measures of two-way ANOVA and paired t-test. Results revealed that the appearance of subtitles at the bottom of the screen changed the eye movement pattern of the participants during the shot changes. Timing of the subtitle starting point (before the cut or after the cut) also aï¬ected the gaze behavior. The editing style, however, did not make any diï¬erence in the gaze behavior of participants while watching subtitled video clips. Further, participants preferred reading subtitles to seeing visual images even if the subtitles were presented during the shot changes.
Este estudio provee una imagen completa del efecto de subtítulos en el comportamiento de la mirada en múltiples participantes viendo películas elaboradas con edición continua y discontinua. Tres videoclips (con y sin subtítulos en inglés) con estilos de edición continua y discontinua fueron presentados a los participantes. Los videoclips fueron extraídos de películas de habla inglesa, y los participantes no eran hablantes nativos de inglés. Tiempo de entrada, tiempo de permanencia, tiempo de primera ï¬jación, trayectoria de escaneo, y duración promedio de ï¬jación, fueron tomados como variables dependientes en este estudio entre grupos. La data de rastreo ocular recolectada fue sometida a un ANOVA de dos vías de medidas repetidas y a pruebas-t pareadas. Los resultados revelaron que la presencia de subtítulos en la parte baja de la pantalla cambió el patrón de movimiento ocular de los participantes durante los cambios de toma. El momento de aparición de los subtítulos (antes o después de los cortes) también afectó el comportamiento de la mirada. Sin embargo, el estilo de edición no generó ninguna diferencia en el comportamiento de la mirada de los participantes mientras veían los videoclips subtitulados. Adicionalmente, los participantes preï¬rieron leer los subtítulos que ver las imágenes visuales, incluso si estos subtítulos se presentaban durante cambios de toma.
RESUMO
O arremesso do basquetebol depende do foco de atenção visual do atleta e relaciona-se ao Olho Quieto (OQ), que pode ser afetado pela ansiedade. Esta revisão buscou estabelecer o estado da arte na literatura sobre o OQ e a sua relação com a ansiedade, observando o seu impacto no desempenho de atletas no arremesso do basquetebol. As buscas foram realizadas nas bases de dados PubMed, PsycInfo, EBSCO, Scielo, Google Acadêmico, Periódicos CAPES e LILACS com os descritores "olho quieto, basquetebol e ansiedade", em português e inglês. Vinte e três documentos foram incluídos na análise. O OQ (fixação visual final com início durante a última etapa motora) caracteriza níveis de habilidade e desempenho. A busca revelou que a ansiedade influencia vários aspectos do arremesso do basquetebol, como a redução da duração do OQ.
The basketball shot depends on the athlete's visual focus of attention so that it is related to the Quiet Eye (OQ) and can be affected by anxiety. This review sought to establish the state of the art in the literature on OQ and its relationship with anxiety, observing their impact on the performance of athletes in the basketball shot. Searches were performed in the databases PubMed, PsycInfo, EBSCO, Scielo, Google Acadêmico, Periódicos CAPES and LILACS with the descriptors "quiet eye, basketball and anxiety" in Portuguese and English. Twenty three documents were included in the analysis. The OQ (final visual fixation starting during the last motor phase) characterizes skill and performance levels. The search revealed that anxiety influences several aspects of the basketball shot, such as reducing the duration of the OQ.
El tiro de baloncesto depende del foco de atención visual del atleta y está asociado con el Ojo Tranquilo (OT), que puede verse afectado por la ansiedad. Esta revisión buscó establecer el estado del arte en la literatura sobre OT y su relación con la ansiedad, observando su impacto en el desempeño de los atletas en el tiro de baloncesto. Las búsquedas se realizaron en las bases de datos PubMed, PsycInfo, EBSCO, Scielo, Google Acadêmico, Periódicos CAPES y LILACS, con los descriptores "ojo tranquilo, baloncesto y ansiedad", en portugués y en ingles. Veintitrés documentos fueron incluidos en el análisis. El OT (fijación visual final que comienza durante el último paso motor) caracteriza los niveles de habilidad y rendimiento. La búsqueda reveló que la ansiedad influye en varios aspectos del tiro de baloncesto, como la reducción de la duración del OT.

BACKGROUND: People with Parkinson's disease (PD) do not differ from neurologically healthy individuals in obstacle circumvention during walking, therefore they are able to use visual feedback adequately to control motor behavior in this task. However, individuals are often distracted by the secondary task when circumventing an obstacle. An increased cognitive load can require prolonged gaze ï¬xation time on a location of interest to compensate for longer information processing duration. RESEARCH QUESTION: To investigate the effects of cognitive dual tasking (DT) on gaze behavior during waking with obstacle circumvention in people with PD and control group, and to determine the impact of gaze behavior on motor strategy. METHODS: Fifteen individuals with PD (PD-group) and 15 neurologically healthy individuals walked at a self-selected speed over a walkway and circumvented an obstacle centered in the walkway. The experimental conditions (5 trials each one) included obstacle circumvention without DT (OC) and obstacle circumvention with DT (OCDT). In the cognitive task, the participant mentally counted the number of times a target number appeared in an audio recording. We analyzed gaze behavior (i.e. number of gaze fixations and duration on the ground and obstacle), standard gait measures and DT cost. Two-way ANOVAs were completed for gait parameters and moment of fixation. RESULTS: There was no significant difference in DT cost between groups and no obstacle contacts. The participants performed a longer mean duration of fixations on the ground during OCDT compared to OC. Group x condition interactions indicated that the PD-group delayed the obstacle fixation relative to the NHI for OCDT (pâ¯<â¯0.001) and presented greater medial-lateral body clearance (pâ¯<â¯0.001) and longer double support time (pâ¯<â¯0.001) during OCDT compared to OC. SIGNIFICANCE: The results of this study suggest that deficits in locomotion during DT in PD-group may be caused, at least in part, by a reduced ability to fixate gaze at appropriate times during walking.

Sociability, defined as the tendency to approach and interact with unfamiliar people, has been found to modulate some communicative responses in domestic dogs, including gaze behavior toward the human face. The objective of this study was to compare sociability and gaze behavior in pet domestic dogs and in human-socialized captive wolves in order to identify the relative influence of domestication and learning in the development of the dog-human bond. In Experiment 1, we assessed the approach behavior and social tendencies of dogs and wolves to a familiar and an unfamiliar person. In Experiment 2, we compared the animal's duration of gaze toward a person's face in the presence of food, which the animals could see but not access. Dogs showed higher levels of interspecific sociability than wolves in all conditions, including those where attention was unavailable. In addition, dogs gazed longer at the person's face than wolves in the presence of out-of-reach food. The potential contributions of domestication, associative learning, and experiences during ontogeny to prosocial behavior toward humans are discussed.
