Need for closure, social impact and the maintenance of Illusory Correlation

The predictions of the Multi Component Model (Van Rooy Vanhoomissen, & Overwalle, 2013) regarding the interaction between Need for Closure (NfC) and social influence on the development and maintenance of illusory correlation (IC) were tested. Participants were given a series of statements about members of two groups (A and B) committing either “bad” or “good” actions. Within a classic IC design, participants formed a more negative stereotype of the minority group B compared to the majority group A, essentially showing an expected illusory correlation between group membership and desirability of behaviour. In an extension to the classic IC paradigm, Need for Closure (NfC) was then manipulated during a novel social influence phase. During this phase, participants rated statements describing the qualities of members of the groups as being true or untrue, either under time pressure (high NfC condition) or not (low NfC condition). After each rating, participants were shown feedback from either one participant (Low Social Impact Condition) or three participants (High Social Impact Condition) taking a stance opposite to the IC effect. Contrary to what was hypothesised, individuals were more likely to change their view of the majority group compared to the minority group when subjected to social influence. Additionally, hypotheses relating to the interaction between social influence and NfC were not supported. We argue that the results indicate the need for more research to explore the interactions between NfC, social influence, and the IC effect.

Analysis and Optimization of Impact Condition of Power Conditioning Inverter Based on ANSYS

This paper uses the professional finite element analysis software ANSYS to process a certain type of power regulating inverter. The overall finite element model of the inverter is established then the three-way impact condition is analysed according to the requirements of GJB 1060.1-91. Through the modal analysis in ANSYS software, the natural frequency and natural vibration mode of the inverter are calculated. Based on modal analysis of the inverter, the DDAM shock spectrum analysis function is used to analyse the impact condition of the inverter. Through the calculation of the impact condition, the deformation and stress state of the inverter structure under various working conditions are obtained. By analysing the calculation results, the weak position of the inverter structure is found and the corresponding optimization scheme is proposed to improve the dynamic performance and improve the electron. The overall dynamic performance of the inverter cabinet also provides an important reference for the design of subsequent electronic cabinets.
