The present research tested a series of theoretically derived competing hypotheses regarding the extent to which different ways of learning about others influence stereotype-relevant impression formation and reliance on stereotypes in stereotype-relevant target evaluations. First, we examined the extent to which stimulus pairing or statement information about novel White (Study 1) and Black (Study 2) targets’ intelligence influenced implicit and explicit impressions of the targets’ competence. In both studies, we found that the two modes of information presentation produced equal effects on impression formation at both the implicit and the explicit levels. In a third study, we compared the effectiveness of stimulus pairing and statement information at reducing or eliminating the influence of stereotypes on implicit and explicit person perception. We found that stereotyping in implicit person perception was completely eliminated by both types of information, but found no evidence of explicit stereotype bias even in the absence of individuating information. Together, the results of the three studies suggest that stimulus pairing and statement target information are equally influential in the formation of stereotype-relevant impressions of novel targets and in eliminating the influence of stereotypes on stereotype-relevant target evaluations. These findings provide support for propositional models of implicit evaluations and for dual-process theories allowing for interaction between different learning systems, but do not support dual-systems theories.

Task Order

The visual location of the information influences the searching efficiency of the monitoring task. In this paper, from the division of human eye’s visual regions, the task searching experiments of visual location in digital interactive interface are conducted. The experimental results show that, for target information blocks in the foveal and the parafoveal regions, the operators can finish the task searching efficiently and rapidly. However, when the target task is away from present fixation range’s parafoveal region, it will easily lead to sequence searching that will cost extra unnecessary task searching time, or even lead to failure of task searching. Therefore, the information layout design of digital interactive interface should be set successively in effective visual locations, i.e., the foveal and the parafoveal regions according to task order. This will satisfy the visual location rule and will efficiently improve the performance of task searching.

Practice Trials

In a same—different judgement task with successively presented signals, subjects matched dots in different vertical positions and tones of different frequencies intramodally and intermodally. The first and second stimuli of trials in each of the four modality conditions were drawn from a set consisting of two, three or five alternatives. In all intermodal set size conditions, the dimensions of pitch and vertical position were related by the same equivalence rule. While intramodal performance improvement depended only on the total number of practice trials at matching on the relevant dimensions, intermodal performance improvement appeared to be related to the number of trials practice with each heteromodal stimulus pairing in a particular set. After performance had approached asymptotic level neither intramodal nor intermodal matching reaction time depended on set size. Mean “same” reaction time was less than mean “different” reaction time, and this difference was greater for intermodal matching than for intramodal matching. The results indicated that intermodal equivalence exists between discrete stimulus values on heteromodal dimensions rather than between the dimensions themselves.

Multiple Uncertainties

Uncertainty should be taken into account when establishing multiobjective task assignment models for multiple unmanned combat aerial vehicles (UCAVs) due to errors in the target information acquired by sensors, implicit preferences of the commander for operational objectives, and partially known weights of sensors. In this paper, we extend the stochastic multicriteria acceptability analysis-2 (SMAA-2) method and combine it with integer linear programming to achieve multiobjective task assignment for multi-UCAV under multiple uncertainties. We first represent the uncertain target information as normal distribution interval numbers so that the values of criteria (operational objectives) concerned can be computed based on the weighted arithmetic averaging operator. Thus, we obtain multiple criteria value matrices for each UCAV. Then, we propose a novel aggregation method to generate the final criteria value matrix based on which the holistic acceptability indices are computed by the extended SMAA-2 method. On this basis, we convert the task assignment model with uncertain parameters into an integer linear programming model without uncertainty so as to implement task assignment using the integer linear programming method. Finally, we conduct a case study and demonstrate the feasibility of the proposed method in solving the multiobjective task assignment problem multi-UCAV under multiple uncertainties.

The subject matter of the article is the radio links of the target information of the space remote sensing systems (Earth remote sensing) from spacecraft of the CUBESAT type. The aim is to study the effectiveness of receiving antennas of different diameters (5 and 12 m), namely, changing the information receiving zone. The goal: to develop a mathematical for determining the minimum reception angles of the target information, taking into account the directional pattern and the flaps of the maximum of the diagram from the direction to the receiving station. Determine the minimum angles of the receiving location of the target information with a given error probability per bit of information (< 10-7) under the condition of different types of on-board transmitting antennas and receive antennas of different diameters. The methods used are: synthesis, mathematical modeling and graphical analysis of the results obtained. The following results are obtained. When using a transmitting helical antenna, the minimum reception angles with a given error probability per bit of information < 10-7 are less by 100 than using a patch antenna. But the value of signal to noise ratio (S/N) when using a helical antenna is dominated by a patch antenna at elevation angles greater than 640, subject to rotation in the direction of the receiving station. When using reflectors with a diameter of 5 m, it is possible to receive information with a specified error probability only for elevation angles greater than 23.50. Thus, the use of reflectors with a diameter of 12 m will significantly increase the possibilities for surveying the Earth's surface due to a longer session of receiving special information. Conclusions. Analysis of the technical characteristics of modern on-board components of spacecraft like CUBESAT has demonstrated the promise of using such spacecraft for environmental monitoring. The study of the CUBESAT satellite radio link was carried out taking into account the directional pattern of the on-board transmitting antenna of the target radio link, using a mathematical model created by the author. Using a patch antenna in comparison with a helix antenna makes it possible to extend the information receiving area with specified quality indicators by 100 by the elevation angle. Comparison of receiving stations with an antenna diameter of 5 and 12 m indicates the prospects of using reflectors of antenna systems with a diameter of 12 m, which are in Ukraine. The use of ground antennas with a reflector diameter of 12 m will allow receiving special information at minimum elevation angles of 120 under the conditions of the calculations (orbit height, on-board transmitter power, data transfer speed).
