Campbell Leaper is a developmental and social psychologist interested in the social construction and the socialization of gender and sexism.  He examines the gender-typing process and its consequences on people's development.  Professor Leaper's work bridges feminist, social-structural, social-cognitive, sociocultural, and social identity theoretical frameworks. For an introduction and an overview of Leaper's conceptual model, see his chapters on "The Social Construction and Socialization of Gender" or "The Socialization of Gender." 

Professor Leaper's research has been featured on televisoin and radio; and in magazine and newspaper articles.

 

 

RECENT RESEARCH PROJECTS

Parental Gender-Typing

Leaper and his students have examined parents' socialization of gender in children and adolescents.

As a research fellow at Harvard Medical School, Dr. Leaper collaborated with Professor Stuart Hauser on a longitudinal study examining how parent-adolescent communication patterns predicted adolescents' later personality development. Of particular note, adolescents' personality development was positively predicted by communication emphasizing independence for girls and by communication emphasizing closeness for boys (see Leaper, Hauser et al., 1989). 

Shortly after joining the faculty at UCSC, Professor Leaper carried out a set of studies funded by a grant from the National Institute of Mental Health. More specifically, these studies investigated parental gender-typing in families with a preschool-age child. Leaper considered aspects of the interactive context as moderators of gender typing. Relevant factors that were examined included the following: child gender, type of toy, parent gender, marital status, parent attitudes, maternal employment, and ethnicity. (For publications that emerged from this project, see the following:  Leaper, Leve, Strasser, & Schwartz, 1995; Leaper & Gleason, 1996; Leaper & Valin, 1996; Tenenbaum & Leaper, 1997; Tenenbaum & Leaper, 1998; Leaper, 2000a.)

One of Professor Leaper's former doctoral students, Harriet Tenenbaum, looked at the possible influences of parents' attitudes and behaviors on gender-related variations in pre-teen children's science and computer learning. Dr. Tenenbaum arranged parents to teach their fifth- or seventh-grade child in various tasks. One set of tasks included demonstrations of physical science phenomena; a second set involved computer programming; and a third set concerned interpersonal dilemmas. Dr. Tenenbaum's dissertation findings indicated gender effects on parents' teaching language during the science tasks (see Tenenbaum & Leaper, 2003.)

Professor Leaper and Harriet Tenenbaum completed a meta-analytic review of the research literature on the effects of parents' gender schemas on children. Their findings indicate an overall effect of parents' gender cognitions that vary in magnitude depending on the type of parent schema and the type of child outcome (see Tenenbaum & Leaper, 2002.)

Leaper has worked with former doctoral student Laura Sabattini to examine differences in young adults' perceptions of the parenting styles of mothers and fathers who are classified as either traditional or egalitarian.  The findings indicate especially strong differences between the ratings of traditional and egalitarian fathers (compared to differences between the ratings of traditional and egalitarian mothers). (See Sabattini & Leaper, 2004.)

Doctoral student Carly Friedman (formerly Raasch) and University of Texas Professor Rebecca Bigler have worked with Professor Leaper on a study investigating how mothers' stereotyped or counterstereotyped comments during a storybook task might be related to children's developing gender schemas. (See Friedman, Leaper, & Bigler, 2007.) 

A current project in collaboration with University of Kentucky Assistant Professor Christia Spears Brown is investigating the role of parents and other relationships in adolescent girls' experiences and perceptions regarding sexism. Parents are being considered as possible sources of discrimination (e.g., discouraging statements regarding achievement) and support. (see Leaper & Brown, 2008.)

Professor Leaper has a chapter on "Parenting Girls and Boys" in Marc Bornstein's second edition of the Handbook of Parenting (see Leaper, 2002). Also, he has a chapter on "The Socialization of Gender" in Joan Grusec and Paul Hastings' Handbook of Socialization (se Leaper & Friedman, 2007). (For another article on parental gender-typing, also see Leaper & Bigler, 2004.)

Gender-Related Self-Concepts, Stereotypes, Attitudes, and Perceptions of Sexism

During the course of his research projects on parental gender typing, Leaper and his students devised the Attitudes Toward Gender (ATG) Questionnaire. The ATG assesses the respondent's attitudes toward equal rights and roles for women and men. (It is adapted from Spence & Helmreich's Attitudes Toward Women Scale.) Both English and Spanish version of the ATG Questionnaire are available on the ATG web page.

A more recent version of the ATG, known as the Pacific Attitudes Toward Gender (PATG) Scale (Vaillancourt & Leaper, 1997), is also available. The PATG is an eclectic combination of items from various gender attitudes questionnaires including Leaper's own ATG. It can be accessed through the PATG web page.

The possible influence of parents' gender schemas on their children was recently investigated in a meta analysis with Harriet Tenenbaum. Their quantitative review indicated a significant and sizable association between parents' gender schemas and various child outcome measures (see Tenenbaum & Leaper, 2002).

In collaboration with University of Kentucky Assistant Professor Christia Brown, Professor Leaper is working on a new project designed to investigate adolescent girls' and young women's self-concepts, their awareness of sexism, coping, and their academic achievement (see Leaper & Brown, 2008; Brown & Leaper, in preparation). One doctoral student, Melanie Ayres, is focusing on how girls and women cope with sexism (see Ayres, Friedman, & Leaper, under review). Another student, Carly Friedman (formerly Raasch), is examining if and how sexual-minority women experience discrimination (Friedman, Ayres, & Leaper, in preparation).  And a third student, Diana Arias, is considering factors related to women's feminist identity (see Arias & Leaper, under review). Finally, a new student, Rachael Robnett, is planning to examine social identity and gender development.

(For other studies related to gender self-concepts, stereotypes, and attitudes, see the following:  Daniels, Sincharoen, & Leaper, 2005; Leaper & Bigler, 2004; Smith & Leaper, 2006; Tenenbaum & Leaper, 2003.) 

Gender Typing in Friendships and Peer Relationships

In addition to studying gender socialization in the family, Leaper has explored how individual and interpersonal psychosocial processes relate to young women's and men's same-gender and cross-gender friendships. He and his students looked at socio-cognitive and social-behavioral factors reflecting self-assertion and affiliation. This included assessments of self-concept, perspective taking, and gender attitudes through a combination of questionnaire and interview measures. Also, communication styles were assessed from videotaped conversations between friends. (For related articles, see the following: Anderson & Leaper, 1998; Leaper, 1994; Leaper, 1998; Leaper & Anderson, 1997; Leaper, Carson, Baker, & Holliday, 1995; Leaper & Holliday, 1995.)

Former graduate student Tara Smith and Dr. Leaper collaborated on a study examining adolescent girls' and boys' perceptions of their gender typicality, peer pressure, peer acceptance, and self-worth (see Smith & Leaper, 2006). They presented model whereby peer acceptance partially mediated the association between perceived gender typicality and self-worth. One implication of the research is that peer rejection may be the most relevant factor linking gender nonconformity and adjustment. Further support for this notion was seen in another study with former graduate student Elizabeth Daniels (see Daniels & Leaper, 2006). They found that peer acceptance mediated the association between athletic participation and adolescents' self-esteem one year. There was full mediation for girls and partial mediation for boys--possibly reflecting the greater importance of peer acceptance for girls participating in traditionally male-dominated pursuits.  

Currently, graduate student Jessica McGuire and Dr. Leaper are examining how socioemotional factors are related to gender-related variations in  social interactions between same-gender and cross-gender friends. They are testing if speaker gender, partner gender, perspective-taking style, or friendship qualities are related to communication during a negotiation task.  They also will be looking at factors related to communication during self-disclosure. 

(For reviews related to gender and peer relations, see Leaper, 1994; Leaper & Anderson, 1997; Leaper & Friedman, 2007; Leaper & Smith, 2004; Leaper & Ayres, 2007).

Communication Processes Coding Schemes

Leaper has devised various classification systems for coding communication strategies. First, he developed the Psychosocial Processes Coding Scheme (PPCS) to analyze the expressions of both assertion and affiliation during social interactions. The PPCS can be used in sequential analyses in order to detect communication patterns between speakers. It includes categorical classifications of communication acts, such as collaboration (high assertion and high affiliation), control (high assertion and low affiliation), oblige (high affiliation and low assertion), and withdraw (low affiliation and low assertion). (See Leaper, 1986; Leaper, 1991; Leaper, Leve, Strasser, & Schwartz, 1995; Leaper, Tenenbaum, & Shaffer, 1999.)

For the latest version of the PPCS coding manual, go to the PPCS Coding Manual web page.

In addition, Leaper devised the Psychosocial Processes Rating Scales (PPRS) that assess levels of Interpersonal Affiliation and Personal Assertion on separate 7-point rating scales (see Leaper, 2000). The Psychosocial Processes Rating Scales can be found on the PPRS web page.

More recently, two other communication coding schemes were developed. The Interpersonal Negotiation Coding Scheme (INCS) classifies communication strategies as either self-emphasizing, other-emphasizing, collaborative, or withdrawing. The INCS is based on Robert Selman's Interpersonal Negotiation Strategies (INS) Interview and his theoretical model of perspective-taking. The Interpersonal Negotiation Coding Scheme is summarized on the Interpersonal Negotiation Coding Scheme web page.

The Self Disclosure and Listener Support Codes classify speakers' personal disclosures as well as the level of overt verbal support provided by the listeners. The coding scheme is based on the system used in Leaper, Carson, Baker, and Holliday's (1995) study. These codes are located on the Self Disclosure and Listener Support Codes web page.

For other articles on language and gender, see the following:  Leaper, 1987; Leaper, Anderson, & Sanders, 1998; Leaper, 1995; Leaper & Bigler, 2004; Leaper & Smith, 2004; Leaper & Ayres, 2007.

  Gender Typing in the Media

Leaper and his students performed a content analysis of children's television programs. They compared the extent that female and male characters are represented in cartoons. Also, they compared the types of behaviors that female and male characters demonstrate as role models. (See Leaper, Breed, Hoffman, and Perlman, 2002.)

Athletic Participation, Gender, and Self Concept

In collaboration with former doctoral students Elizabeth Daniels and Sirinda Sincharoen, Professor Leaper investigated the relation between athletic participation, gender, and self concept in children and adults. One study examined relations between gender, sport motives, and athletic identity among adolescents attending summer sports camps (see Daniels, Sincharoen, & Leaper, 2005). Another study involved a longitudinal investigation of sport participation, peer acceptance, and self-esteem among adolescent girls and boys (see Daniels & Leaper, 2006). More recently, Professor Leaper and University of Kentucky Assistant Professor Christia Brown examined adolescent girls' experiences with sexism regarding their athletic abilities (see Leaper & Brown, 2008). 

Schools and Academic Achievement

One of Professor Leaper's ongoing research interests concerns gender inequities in schools and academic achievement. In particular, he is interested in social factors that contribute to gender inequities in science achievement. In one study, fathers were found to treat daughters and sons differently during science teaching tasks but not during non-science teaching tasks (see Tenenbaum & Leaper, 2003).

Currently, Professor Leaper is working with University of Kentucky Assistant Professor Christia Brown to assess if and how adolescent girls' awareness of gender discrimination may affect their academic achievement. (See Leaper & Brown, 2008; Brown & Leaper, in preparation.)

Meta-Analyses of Language and Gender Studies

Leaper and his students have been reviewing the research literature on gender differences in language and communication. To do this, they have been using meta-analytic techniques that examine overall effect sizes as well as various moderator variables. In the first meta-analysis, studies looking at parents' language behavior to their children were reviewed. Both parent gender (modeling) and child gender (differential treatment) effects on parents' total amount of talking, assertive/instrumental speech, and affiliative/supportive speech were considered. The analyses revealed systematic gender-related differences in language behavior. However, the effects were significantly larger depending on particular contextual variables such as the child's age and the activity setting. In these ways, the research lends support to both social cognitive and sociocultural approaches. (See Leaper, Anderson, & Sanders, 1998.)

Another meta analysis examined moderators of gender effects in adults' conversational interruptions. A negligible effect size for gender was indicated across studies. However, when other factors were taken into account--such as the operatoinal definition and aspects of the interactive setting--small to medium effect sizes indicated a greater use of interruption among men than women. (See Anderson & Leaper, 1998.)

Also, Leaper has completed a meta-analysis examining moderators of gender effects on talkativeness, affiliative, speech, and assertive speech in children (see Leaper & Smith, 2004) and adults (see Leaper & Ayres, 2007).


 

PRACTICAL IMPLICATIONS 

OF RESEARCH PROGRAM


Professor Leaper's research examines the social construction and socialization of asymmetries in girls'/women's and boys'/men's expectations, preferences, abilities, and status. His work considers how gender is created and maintained in the contexts of the family, schools, close relationships, the mass media, and the work world. Professor Leaper's research suggests possible ways for fostering greater gender equality at both the interpersonal and societal levels.
