We performed three experiments to investigate whether adjectives can modulate the sensorimotor activation elicited by nouns. In Experiment 1, nouns of graspable objects were used as stimuli. Participants had to decide if each noun referred to a natural or artifact, by performing either a precision or a power reach-to-grasp movement. Response grasp could be compatible or incompatible with the grasp typically used to manipulate the objects to which the nouns referred. The results revealed faster reaction times (RTs) in compatible than in incompatible trials. In Experiment 2, the nouns were combined with adjectives expressing either disadvantageous information about object graspability (e.g., sharp) or information about object color (e.g., reddish). No difference in RTs between compatible and incompatible conditions was found when disadvantageous adjectives were used. Conversely, a compatibility effect occurred when color adjectives were combined with nouns referring to natural objects. Finally, in Experiment 3 the nouns were combined with adjectives expressing tactile or shape proprieties of the objects (e.g., long or smooth). Results revealed faster RTs in compatible than in incompatible condition for both noun categories. Taken together, our findings suggest that adjectives can shape the sensorimotor activation elicited by nouns of graspable objects, highlighting that language simulation goes beyond the single-word level. 相似文献

Echo phonology was originally proposed to account for obligatory coordination of manual and mouth articulations observed in several sign languages. However, previous research into the phenomenon lacks clear criteria for which components of movement can or must be copied when the articulators are so different. Nor is there discussion of which nonmanual articulators can echo manual movement. Given the prosodic properties of echoes (coordination of onset/offset and of dynamics such as speed) as well as general motoric coordination of various articulators in the human body, we expect that the mouth is not the only nonmanual articulator involved in echo phonology. In this study, we look at a fixed set of lexical items across 36 sign languages and establish that the head can echo manual movement with respect to timing and to the axis/axes of manual movement. We propose that what matters in echo phonology is the visual percept of temporally coordinated movement that repeats a salient movement property in such a way as to give the visual impression of a copy. Our findings suggest that echoes are not obligatory motor couplings of two or more articulators but may enhance phonological distinctions that are otherwise difficult to see. 相似文献

Conscious and unconscious emotions are related to mental rotation. In this study, we investigated if also unconscious emotional evaluations of the stimuli are related to mental rotation performance. 114 students (39 men, 75 women) solved implicit and explicit affective evaluations and a psychometric mental rotation test with cube and pellet figures. Furthermore, the use of spatial toys, the stereotyping of spatial abilities, and the self-rating in spatial abilities were registered. The mental rotation test with pellet figures was more difficult than the one with cube figures. Mental rotation performance was predicted by the self-rating of spatial abilities. For the cube figures, it was additionally predicted by the implicit affective evaluation of those figures. The results did not differ between men and women. The study provides evidence for a relation between affective emotional evaluations and mental imagery processes, although this does not hold true for all stimulus types. 相似文献

While suicide is recognised as one of the leading causes of death in Australia, it is often presumed that fatal road crashes are primarily accidental in nature. However, international research has indicated that deliberate attempts at self-harm while driving may account for between 1.1% and 7.4% of road crashes. Despite the personal and financial costs associated with such events, few studies have examined the extent of motor vehicle suicides (MVS) or the circumstances surrounding such incidents in Australia. Given this, the current study reviewed coronial, police and toxicology findings of 762 motor vehicle fatalities in Queensland (Australia) during the period 2011 to 2015 to determine the frequency of confirmed cases and explore the prevalence (and characteristics) of possible MVS that remain undetected. In total, 22 confirmed cases were identified, and such events shared significant similarities with 14 possible events, including evidence of recent emotional upset, adversity and mental health diagnoses. In contrast, differences between the groups were limited to confirmed cases being more likely to involve males and contain a suicide note or evidence of past suicidality, while possible cases were more likely to involve a multiple vehicle impact with a truck. Importantly, crucial information regarding the deceased’s psychological state and life circumstances (e.g., psychological autopsy) was not reported in many cases. Corresponding qualitative analysis of the coroners final determination (between the two groups) revealed the occurrence of the word suicide to occur seven times (31.8%) among confirmed cases and five times (35.7%) for possible casers. Furthermore, the coroners final determination of intent to suicide was open or undetermined in six of the possible cases (43%), which further suggests a reluctance (or procedural uncertainty) to categorically identify MVS. The paper further reviews the main findings, illuminates core challenges associated with identifying MVS and proposes a need for future investigations to incorporate a more standardised and evidence-based approach in order to effectively identify such events. 相似文献

Social facilitation proves robust in conditioning tasks (e.g., running), yet in coordination tasks (e.g., rifle-shooting) some studies report performance deterioration. Recent Biathlon World Cup data offered the unique opportunity to test this task-specificity (conditioning = cross country skiing, coordination = rifle-shooting). Audience restrictions due to COVID-19 allowed to compare athletes' performance in the absence (2020) and presence (season 2018/2019) of an audience. Gender-specific regulations (e.g., course length) necessitated the inclusion of gender as additional factor. Results of 83 (sprint competition) and 34 (mass start competition) biathletes revealed that task-specific social facilitation is moderated by gender: In the presence of an audience male biathletes showed performance improvements in the conditioning task and performance deteriorations in the coordination task; female biathletes showed the reverse pattern. This gender dependency may have gone unnoticed in the past due to sample selection bias (<1/3 female), thereby questioning the generalizability of social facilitation theory. 相似文献

An accurate estimate of one’s performance is an important prerequisite for success, and prevents people from taking excessive risks. Based on the selection-margins paradigm (Riediger et al., 2006), the current paper assessed maximum speed rope-skipping (study 1), soccer dribbling (study 2), and the fine motor task of tracing (study 3) in 5- to 37-year-olds. Participants predicted their performances for the upcoming trial. The better the predicted performance, the more points were gained in case of success. To discourage overestimations, participants received no points for unsuccessful trials. In rope skipping, older and more experienced athletes outperformed the beginners, and had fewer trials with 0 points. In soccer dribbling and tracing, older individuals again showed less overestimation, as reflected by a smaller deviation of predicted and actual performance (selection margins) and fewer 0 point trials. Athletes and coaches should be aware that younger and less-experienced athletes tend to overestimate their motor performances. 相似文献

The link between visual-motor integration (VMI) and executive functions (EF) has been repeatedly documented in preschool children. VMI is often assessed using the Copy Design task measuring the product, thereby neglecting the processes that lead to a specific copy. Furthermore, EF are assumed to be mainly involved when a task is new. The involvement of EF after minimal practice in VMI, however, is unknown. Therefore, the present study investigated product- (i.e., accuracy) and process-based measures, namely velocity, and fluency, in five consecutive trials of copying shapes. Contributions of manual dexterity and EF to both VMI product and VMI processes across five trials were investigated in a sample of 5- to 6-year-old kindergarten children. Results revealed that children did not copy the shapes more accurately across the five trials, but quicker and more fluently. In line with previous findings, children's performance on VMI, manual dexterity, and EF were interrelated. The results indicate that over and above the copy's accuracy, also fluency of copying is a crucial indicator of VMI, which is related to EF and manual dexterity. Furthermore, findings on the VMI–EF link point to strong EF involvement during copying when the task is new and to a decreasing EF involvement with increasing practice, already after five trials. New insights into VMI in preschool children are discussed with regard to underlying cognitive processes. 相似文献

A substantial body of research has converged on the idea that the sense of agency arises from the integration of multiple sources of information. In this study, we investigated whether a measurable sense of agency can be detected for mental actions, without the contribution of motor components. We used a fake action-effect paradigm, where participants were led to think that a motor action or a particular thought could trigger a sound. Results showed that the sense of agency, when measured through explicit reports, was of comparable strength for motor and mental actions. The intentional binding effect, a phenomenon typically associated with the experience of agency, was also observed for both motor and mental actions. Taken together, our results provide novel insights into the specific role of intentional cues in instantiating a sense of agency, even in the absence of motor signals. 相似文献

IntroductionThe Object Spatial Imagery and Verbal Questionnaire (OSIVQ) measures individual differences in Visual-Verbal cognitive style and distinguishes between spatial and object visual imagery.ObjectiveThe aim of this study was to evaluate the psychometric properties of a French version of the OSIVQ.MethodSeven hundred fifty-two participants completed the French OSIVQ and 144 of them also completed a paper-and-pencil assessment to evaluate spatial imagery, object imagery and verbal abilities.ResultsPrincipal component analyses of the OSIVQ showed good internal construct validity. Results also revealed pronounced individual differences and a significant gender effect. Confirmatory factorial analyses gave support to a three-dimensional model of cognitive style. Furthermore, correlations were observed across the different dimensions of the questionnaire and specific paper-and-pencil tasks.ConclusionOur results highlight the good psychometric properties of the French version of the OSIVQ. 相似文献
