Ten subjects were asked to report both of two different consonant-vowels (CVs) presented to the same foveal area, but in different eyes (“dichoptically”). Stimuli were presented at stimulus-onset asynchronies (SOAs) ranging from 0 to 150 msec in 25-msec steps. Correct identifications were significantly depressed for the eye receiving the leading stimulus at SOAs of 25 to 75 msec. Monoptic data from three subjects indicated no significant reductions in correct identification as a function of SOA. The dichoptic results can be understood in terms of current theories of visual backward masking and are similar to the “lag effect” observed with dichotic listening to speech stimuli. Similarity of results for the two modalities suggests a similar “two-process” explanation may underlie both phenomena. 相似文献

We report an experiment that evaluates whether BLANK or an unrelated prime is a more suitable baseline for assessing priming for an ERP study. Sixteen subjects performed a lexical decision task with a 1 s prime-target stimulus onset asynchrony. Increased amplitude for the N400 was observed for targets in the unrelated prime condition whereas targets in the BLANK prime condition evoked activity that was more like that in the related prime condition. Theoretically, we conclude that the N400 reflects semantic integration. Pragmatically, we conclude that the BLANK prime is a better neutral prime but that unrelated primes yield stronger N400 effects. 相似文献

The COVID-19 pandemic and violence against people of Color during 2020 brought troubling racial inequities to the forefront of American discourse. In line with the Critical Consciousness (CC) and Social Justice Youth Development (SJYD) frameworks, emerging adults may have developed their capacity for critical reflection, motivation, and action against systemic inequities. We drew from interviews with 27 emerging adults (ages 18–23) across the US, and used thematic analysis to explore differences in their reflections, motivations to act, and actions based on their racial/ethnic identification. We found nuanced variability in their critical reflections based on self, social, or global awareness and experiences of marginalization. White and Asian emerging adults used vague language or expressed feeling their reflections were insufficient. Black and Latinx emerging adults emphasized the importance of education and raising awareness. Although all emerging adults took action based on a sense of duty, few engaged in critical action; decisions to take in-person action varied based on whether they viewed racism or COVID-19 as a greater threat. Findings demonstrate that emerging adults' experiences of racialization may have related to their CC development. We share implications for community psychologists conducting antiracist research addressing White fragility and dismantling racial hierarchy. 相似文献

Chen and Dunlap (1993) added to the growing list of papers promoting the use of randomization tests in statistical testing. Their particular contribution was an SAS program that could bring computation of these tests to a wider audience. The present paper points to several problems with the presentation of Chen and Dunlap and provides solutions to these problems. It is concluded that randomization tests deserve more attention, but that they are best computed by programs written in a low-level programming language or, if using SAS on a mainframe, by using the MULTTEST procedure. 相似文献

Although lay people know that various diseases can be inherited, the idea that unhealthy life styles are the crucial cause of ill health has been promoted by health education policy in the United Kingdom. However, a new paradigm seems to be developing. The medical profession is increasingly using genetics to explain ill health, and people are being referred to geneticists for information and counseling. Lay conceptions of genetic disease emerged during this qualitative study of the process of genetic counseling. The results reported in this paper suggest that many lay people lack knowledge of genetics and inheritance, and that there is considerable stigma attached to genetic disease. Misconceptions and fears may not always be recognized or resolved during the process of genetic counseling. The implications of such misunderstandings and beliefs are considered in this paper. 相似文献

Four investigations were carried out to assess the feasibility of using eye movement measures as indices of mental workload. In the first experiment, saccadic extent was measured during free viewing while subjects performed low, moderate and high complexity, auditory tone counting as the workload tasks. The range of saccadic extent decreased significantly as tone counting complexity (workload) was increased. In the second experiment the range of spontaneous saccades was measured under three levels of counting complexity with a visual task that did not require fixation or tracking. The results indicated that the extent of saccadic eye movements was significantly restricted as counting complexity increased. In the third experiment, the effects of practice were examined and decreased saccadic range under high tone counting complexity was observed even when significant increases in performance occurred with practice. Finally, in experiment 4, the first experiment was repeated with additional optokinetic stimulation and the saccadic range was again observed to decrease with tone counting complexity. The results indicated that the extent of spontaneous and elicited eye movements was significantly restricted as counting complexity increased. We conclude that this measure may provide a valuable index of mental workload. 相似文献

Behavioral commitment levels of group members were examined under conflict of interests between individual and collective tasks in a work-group scenario. Commitment was conceptualized as the amount of time and effort resources that individuals chose to allocate to the group task. Seventeen groups of three allocated 100 time and effort resource units to individual and group tasks for each of four trials. The level of commitment to group work increased, partially because over-rewarded persons increased group contributions more than underrewarded persons decreased them. However, the variance of allocations to the group task did not decrease over trials. Potential implications of the findings for organizational research and practice concerning work groups are discussed in terms of the roles of equity, comparative referent use, and information exchange. 相似文献
