It questions the assumption of a single function made in formal models of social influence and proposes instead that the function will vary depending on which social influence process predominates. It is argued that normative influence is likely to be stronger when participants make public responses and are face-to-face with the majority, whereas informational influence is likely to be stronger when participants make private responses and communicate with the majority indirectly.

  • Cultural Value Changes from Collectivism to Individualism in Chinese Commercials
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by K-State Research Exchange From us to me: Cultural value changes from collectivism to individualism in Chinese commercials by Jingyan Zhao B.S., Jilin University, 2013 A THESIS submitted in partial fulfillment of the requirements for the degree MASTER OF SCIENCE Department of Journalism and Mass Communications College of Arts and Sciences KANSAS STATE UNIVERSITY Manhattan, Kansas 2017 Approved by: Major Professor Curtis Matthews Copyright © Jingyan Zhao 2017. Abstract China’s society has been changing since 1979, when the open-door policy was implemented. Many great events in politics, economy and culture have brought lots of diversities to the Chinese younger generation who were born after 1979. These diversities have led to a cultural value change from collectivism to individualism among this generation (Cao, 2009; Sun & Wang, 2010; Moore, 2005). Cultivation analysis theory may be appropriate to explain this phenomenon as the open-door policy allowed American and European TV programs and other media products come into China. Effective advertising should cater to its audience in order to effectively persuade them to purchase its merchandise or service (Zhang & Harwood, 2004; Chang, 2006). If the cultural value of the Chinese younger generation has changed, it may be reflected in the commercial content of successful advertisers. This research conducted a content analysis of Chinese commercials, comparing the commercial contents in recent years to approximately ten years ago. It examined if the individualistic factors were more frequently showed in the commercials in recent years than approximately ten years ago, with the consideration to merchandise type and production place.

A GENERATIONAL STUDY OF COLLECTIVISM IN THE UNITED STATES TYLER CARTER 33 Pages A number of past sociopolitical studies have attempted to highlight the ways in which generational identity, which develops when people come of age in different times, affects political attitudes. In this study, I investigate generational influence on the degree to which individuals embrace collectivist values, as considered by examinations of social policy attitudes and trust in government. A measure of attitudes towards social policies arguably represent collectivist values because social policy is designed to prioritize the group over the individual. A subsequent measure of trust in government augments the discussion of collectivist values because the formation of democratic political institutions occurred out of the necessity for widespread collective problem-solving. Regression analyses across the various models indicate that generation has little to no effect on collectivist values. Instead, political ideology, socioeconomic status, and sociodemographic status are more indicative of collectivist values in the United States.

  • Cross-Cultural Differences in Helping Strangers
    JOURNAL OF CROSS-CULTURAL PSYCHOLOGY Levine et al. / CROSS-CULTURAL DIFFERENCES IN HELPING STRANGERS Independent field experiments in 23 large cities around the world measured three types of spontaneous, nonemergency helping: alerting a pedestrian who dropped a pen, offering help to a pedestrian with a hurt leg trying to reach a pile of dropped magazines, and assisting a blind person cross the street. The results indi- cated that a city’s helping rate was relatively stable across the three measures, suggesting that helping of strangers is a cross-culturally meaningful characteristic of a place; large cross-cultural variation in helping emerged, ranging from an overall rate of 93% in Rio de Janeiro, Brazil, to 40% in Kuala Lampur, Malaysia. Overall helping across cultures was inversely related to a country’s economic productivity; countries with the cultural tradition of simpatia were on average more helpful than countries with no such tradition. These findings constitute a rich body of descriptive data and novel hypotheses about the sociocultural, economic, and psychological determinants of helping behavior across cultures. CROSS-CULTURAL DIFFERENCES IN HELPING STRANGERS ROBERT V. LEVINE California State University, Fresno ARA NORENZAYAN University of Michigan KAREN PHILBRICK California State University, Fresno Anecdotal observation and empirical research suggest that strangers are more likely to receive help in some cities than they are in others (e.g., Steblay, 1987). These differences have been explained by theories from a number of perspectives, ranging from explanations focusing on the importance of objective demographic indicators like population size (e.g., Milgram, 1970), rate of population change (e.g., Rubington & Weinberg, 1977), and eco- nomic prosperity (e.g., Linsky & Straus, 1986) to those focusing on subjectively measured social-psychological variables such as cultural values (e.g., Triandis, 1989).

  • How Does Individualism-Collectivism Relate to Bullying Victimisation?
    International Journal of Bullying Prevention https://doi.org/10.1007/s42380-018-0005-y ORIGINAL ARTICLE How Does Individualism-Collectivism Relate to Bullying Victimisation? Peter K. Smith 1 & Susanne Robinson1 # The Author(s) 2019 Abstract Large-scale surveys have pointed to considerable country variations in the prevalence and nature of bullying victimisation. In seeking to explain these, one possible explanatory factor has been the cultural values of a country, such as expounded by (Hofstede 1980; Hofstede et al. 2010). Of his six dimensions of cultural values, the most investigated in relation to aggression and bullying has been that of individualism-collectivism (IDV). The theoretical background and several empirical studies have suggested more aggression in individualist societies, but the evidence has been mixed and often based on small samples. Here, we investigate how the prevalence of victimisation in different countries relates to IDV. We also examine predictions about the proportion of bullying which is relational and the ratio of bullies to victims. We primarily used the Health Behaviour in School- aged Children surveys, available at 3 age groups and over six time points. We also use data from 4 other surveys where appropriate. The overall findings are for less victimisation in individualist societies, but only in more recent years; some support for a greater proportion of relational victimisation in individualist societies and a higher ratio of bullies to victims in collectivist societies. The findings are discussed in relation to other factors, and a hypothesis is advanced that regulatory frameworks and resources have reduced victimisation primarily in more individualist societies in the last two decades.

  • Authoritarian Parenting in Individualist and Collectivist Groups: Associations with Maternal Emotion and Cognition and Children’S Self-Esteem
    Journal of Family Psychology Copyright 2006 by the American Psychological Association 2006, Vol. 20, No. 1, 68–78 0893-3200/06/$12.00 DOI: 10.1037/0893-3200.20.1.68 Authoritarian Parenting in Individualist and Collectivist Groups: Associations With Maternal Emotion and Cognition and Children’s Self-Esteem Duane Rudy and Joan E. Grusec University of Toronto Mothers and children between the ages of 7 and 12, from individualist (Western European) and collectivist (Egyptian, Iranian, Indian, and Pakistani) backgrounds, completed assess- ments of children’s self-esteem, maternal authoritarianism, and mothers’ thoughts and feel- ings about their children. Collectivist mothers endorsed authoritarian parenting more than did individualist mothers but did not feel or think more negatively about their children, and collectivist children were not lower in self-esteem. Within both groups, maternal negative affect and cognition were associated with lower self-esteem in children. However, maternal authoritarianism was associated with maternal negative emotion and cognition only in the individualist group. The results suggest that maternal negative thoughts and feelings, asso- ciated with authoritarianism in individualist but not collectivist groups, may be more detrimental to children’s self-esteem than is authoritarianism in and of itself.

  • Cross‐Cultural Phenomenology of Obsessive‐Compulsive Disorder M
    4 Cross‐Cultural Phenomenology of Obsessive‐Compulsive Disorder M. T. Williams, L. K. Chapman, J. V. Simms, and G. Tellawi Introduction Obsessive‐compulsive disorder (OCD) is a debilitating mental disorder, involving dis- tressing obsessions and repetitive compulsions. Obsessions are intrusive, unwanted thoughts, images, or impulses that increase anxiety, whereas compulsions are repeti- tive behaviors or mental acts used to decrease anxiety. OCD appears in every culture, with the earliest reports dating back to the first half of the second millennium BC, described in ancient Babylonian texts. Although they had little knowledge of the brain or psychological functions, Babylonian physicians carefully recorded the abnormal behaviors that we now recognize as OCD. One such text states that the sufferer, “does not know why he has a morbid fear of beds, chairs, tables, lighted stoves, lamps, etc., of leaving or entering a city, city gate, or house, or of a street, temple, or road” (Reynolds & Wilson, 2011). We do not know how many people suffered from OCD in ancient times, but in the contemporary United States, the National Comorbidity Survey Replication (NCS‐R) found that approximately 1.6% of the population met criteria for OCD within their lifetime (Kessler et al., 2005a), with 1% of the sample meeting criteria within the last year (Kessler, Chiu, Demler, Merikangas, & Walters, 2005b). The prevalence of OCD appears to be roughly consistent across US ethnic groups, with African and Caribbean Americans having shown an OCD lifetime prevalence of 1.6% (Himle, et al., 2008). Epidemiologic studies conducted in other countries find similar rates cross‐nationally (Weismann et al., 1994), ranging from 0.3% in Brazil to 2.7% in Hungary.

  • Bandwagon Effect: Lesson Plan
    Bandwagon Effect: Hop On! Bandwagon Effect: Lesson Plan Topic The bandwagon effect is the psychological phenomenon in which an individual does something because others, particularly a large group of others, are doing it. This action or behavior is done regardless of whether it aligns with the individual’s personal belief or even factual evidence. Possible subjects/classes Time needed ● Psychology ● English 30-45 minutes ● Economics/Marketing ● Politics Video link: https://academy4sc.org/topic/bandwagon-effect-hop-on/ Objective: What will students know/be able to do at the end of class? By the end of this lesson, students will be able to ● Define the bandwagon effect. ● Explain how and why the bandwagon effect functions in every social field. ● Combat the bandwagon effect in their daily lives. Key Concepts & Vocabulary Conformity, bandwagaon Materials Needed A popular song and device to play music for the introductory activity Before you watch If you can get student confidants in on your plan, play popular, well-known music in your classroom. Encourage students to sing along. You’ll need student confidants because students are highly unlikely to actually sing in your classroom without outside motivation. Your confidants should be able to attract students not in on the plan to join in. Bandwagon Effect: Hop On! If you fail to get students to sing, whether your confidants did not attract students or you decided against using confidants, this can also be learning experience. Regardless of the results, question students about what just happened. Why did no one or few people sing at the beginning? Encourage students to think beyond simple answers like “I didn’t want to” or “I didn’t know the lyrics” to deeper responses.
