How the behavioral approach system predicts everyday life outcomes

This study tested crucial components of Gray's reinforcement sensitivity theory that have generally been overlooked in the literature. We tested whether the perceived amount of reward moderates the behavioral approach system (BAS) and the importance of reward mediates BAS in the prediction of job satisfaction and organizational commitment. Results from 514 participants employed in part-time and full-time jobs provided support for our model, such that the indirect effect of BAS through the importance of reward was strongest when reward was provided. This model advances our understanding of reinforcement sensitivity theory and offers a solid foundation for predicting outcomes in everyday life.     

Is manipulation of mood a critical component of cognitive bias modification procedures?

This paper investigates whether changes in mood state are an important component of cognitive bias modification (CBM) procedures. In a novel CBM procedure participants read either positive or negative statements relating to social issues for 5 min. Interpretation bias was measured by means of a scrambled sentence test, which was presented both before and after the CBM procedure. Participants who read the positive statements made more positive resolutions to the scrambled sentences, while participants who read the negative statements made more negative resolutions. Thus, the appropriate positive and negative interpretative biases were induced by the CBM procedure. However, significant mood changes also occurred following CBM. In Experiment 2, a musical mood induction procedure was presented with depressing or elating music. As before, a scrambled sentence test was presented both before and after the musical mood induction. Mood changed in accordance with the valence of the music to the same extent as with CBM. Critically however, performance on the scrambled sentence task did not change for both groups. This demonstrates that a change in mood state is not sufficient for a change in cognitive bias to occur.     

Prejudiced People Perceive More Community Support for Their Views: The Role of Own,Media, and Peer Attitudes in Perceived Consensus

People often overestimate others' support for their views (false consensus effect). Recent research has shown that this is particularly marked in the relation between perceived consensus and prejudice. The current research asked whether this partly arises in an in‐group stereotype of the community as prejudiced. We investigated relations between different sources of normative information (self, media, peers), estimates of community attitudes, and perceived consensus in a sample of 135 community members. Media prejudice predicted community attitudes, and this further predicted consensus. However, strongest was a direct relation between own prejudice and perceived consensus. The results indicate a desire to appear nonprejudiced, relative to others. Confronting prejudiced people with information about community norms is a promising intervention under these circumstances.     

Does emotion processing require attention? The effects of fear conditioning and perceptual load

This study examined the impact of perceptual load on the processing of unattended threat-relevant faces. Participants performed a central letter-classification task while ignoring irrelevant face distractors, which appeared above or below the central task. The face distractors were graded for affective salience by means of aversive fear conditioning, with a conditioned angry face (CS+), an unconditioned angry face (CS-), and a neutral control face. The letter-classification task was presented under conditions of both low and high perceptual load. Results showed that fear conditioned (i.e., CS+) angry face distractors interfered with task performance more than CS- angry or neutral face distractors but that this interference was completely eliminated by high perceptual load. These findings demonstrate that aversively conditioned face distractors capture attention only under conditions of low perceptual load.     

Exploring lexical co-occurrence space using HiDEx

Hyperspace analog to language (HAL) is a high-dimensional model of semantic space that uses the global co-occurrence frequency of words in a large corpus of text as the basis for a representation of semantic memory. In the original HAL model, many parameters were set without any a priori rationale. We have created and publicly released a computer application, the High Dimensional Explorer (HiDEx), that makes it possible to systematically alter the values of these parameters to examine their effect on the co-occurrence matrix that instantiates the model. We took an empirical approach to understanding the influence of the parameters on the measures produced by the models, looking at how well matrices derived with different parameters could predict human reaction times in lexical decision and semantic decision tasks. New parameter sets give us measures of semantic density that improve the model’s ability to predict behavioral measures. Implications for such models are discussed.     

Exercise dependence and the drive for muscularity in male bodybuilders,power lifters,and fitness lifters

Researchers have hypothesized differences in exercise dependence and drive for muscularity between bodybuilders and power lifters, while others have not found the predicted differences. This study assessed 146 weight lifters (bodybuilders, n = 59; power lifters, n = 47; fitness lifters, n = 40) on the Exercise Dependence Scale, Bodybuilding Dependence Scale, and the Drive for Muscularity Scale. Results showed that bodybuilders and power lifters were significantly higher than fitness lifters on EDS Total, 7 EDS scales, and the 3 BDS scales. In contrast, power lifters were found to be significantly higher on DMS Total and DMS Behavior scales than bodybuilders. The regression results suggest that exercise dependence may be directly related to the drive for muscularity.     

Social Dominance Orientation and Right-Wing Authoritarianism: Additive and Interactive Effects

The additive and interactive effects of Social Dominance Orientation (SDO) and Right-Wing Authoritarianism (RWA) were examined using 16 independent samples of New Zealand European participants ( N =  2,164). Consistent with Duckitt's (2001) Dual Process Model, SDO and RWA displayed strong additive effects across various domains of intergroup-related attitude, including measures of racism, sexism, homosexual prejudice, and ethnic and religious ingroup identification. In each of these five domains, meta-analysis indicated that the statistical interaction of SDO and RWA accounted for an average of less than .001% variance in addition to their linear combination. It is concluded that the association between SDO and various discriminatory attitudes and beliefs is only extremely weakly dependent on RWA, and vice-versa, suggesting that these two ideological attitudes are primarily additive, rather than interactive, in nature.     

Parental Psychopathology and Paternal Child Neglect in Late Childhood

We aimed at determining the association of both severity of paternal and maternal substance use disorder (SUD) and psychiatric disorders with paternal child neglect severity during late childhood. The sample comprised 146 intact SUD (n=71) and non SUD (n=75) families with a 10–12 year old female or male biological offspring. The average age of fathers, mothers, and children was 44 (SD=5.9), 42 (SD=4.78), and 11 (SD=.79) years, respectively. The ethnic composition was 85% Caucasian and 15% African American. The results showed that paternal and maternal SUD and psychiatric disorders severity was correlated with paternal child neglect severity. However, paternal psychopathology failed to achieve significance in the regression analyses. Severity of maternal, especially severity of antisocial personality disorder symptoms was associated with paternal child neglect. These results are discussed within the framework of evolutionary psychology research examining paternal investment in the offspring. Implications for the necessity of identifying parental psychopathology and an integrated treatment approach are discussed.     

Making Sense of Heterosexuality: An Exploratory Study of Young Heterosexual Identities in Turkey

On the basis of the understanding that the shaping, experience, and meaning of sexual identities is informed by the social context, an exploratory study of sexual identities was done with a college sample in urban Turkey. Participants included 225 students taking an introductory psychology course at a private urban university in İstanbul (66.5% women, 33.5% men, age range: 18–30 years, M=20.1, SD=1.7, 98% heterosexual identified). A questionnaire was used to investigate how young people explain the development of their sexual identity and how it affects their lives. An overwhelming majority identified their sexual identity, feelings, and experiences as always having been the same and were quite confident that their sexual identity would remain the same into the future. Participants saw their heterosexuality as mostly having to do with ‘outside forces’ including general references to the role of society, culture, and social expectations and norms, family structure and socialization, peer relations, and modeling. Most perceived their sexual identity to have a positive effect on their lives. Results suggest some evidence of interest in and openness to considering issues of sexual identity among these young people, and are discussed in the context of previous research on heterosexual identity development, sociocultural factors, and with reference to the historical meanings of sexual identities and practices in Turkey.     

“Our Revolution Has Style”: Contemporary Menstrual Product Activists “Doing Feminism” in the Third Wave

An in-depth content analysis of five web sites and eight paper zines (self-produced and distributed magazines) was conducted to uncover the inspiration, content, and unique strategies associated with text -based contemporary menstrual product activism. Menstrual product activism is loosely defined as various attempts to expose the hazards of commercial “feminine protection” to both women's bodies and the environment and the promotion of healthier, less expensive, and less resource-intensive alternatives. This activism's discourse draws on many traditions to produce its resistance to mainstream menses management. The movement, first and foremost, is the legacy of several decades of related activism, dating to the mid1970s. Contemporary menstrual product activism updates and modifies this tradition with the “do it yourself” ethic and anti-corporate philosophy of Punk culture and Third Wave feminist ideals of anti-essentialism, inclusion, humor, irony, and reappropriation. To date, this activist agenda has received little scholarly attention, yet it promises to yield meaningful insight into so called Third Wave feminist theory and practice and reveal the resilience of a woman-centered modern history of resistance.
