Training and the attentional blink: Limits overcome or expectations raised?

The attentional blink (AB) refers to a deficit in reporting the second of two sequentially presented targets when they are separated by less than 500 ms. Two decades of research has suggested that the AB is a robust phenomenon that is likely attributable to a fundamental limit in sequential object processing. This assumption, however, has recently been undermined by a demonstration that the AB can be eliminated after only a few hundred training trials (Choi, Chang, Shibata, Sasaki, & Watanabe in Proceedings of the National Academy of Sciences 109:12242–12247, 2012). In the present work, we examined whether this training benefited performance directly, by eliminating processing limitations as claimed, or indirectly, by creating expectations about when targets would appear. Consistent with the latter option, when temporal expectations were reduced, training-related improvements declined significantly. This suggests that whereas training may ameliorate the AB indirectly, the processing limits evidenced in the AB cannot be directly eliminated by brief exposure to the task.     

Assessing Parenting Behaviors in Euro–Canadian and East Asian Immigrant Mothers: Limitations to Observations of Responsiveness

The use of parenting measures that are developed for use with Western families without testing their validity among families from non-Western cultural backgrounds may not be appropriate. Similar parenting behaviors may affect child outcomes in different ways across different cultures. This study examined the cross-cultural validity of an observational Maternal Responsiveness coding system and of self-reports of lax/inconsistent parenting in Euro–Canadian (n = 23) and East Asian immigrant mothers (n = 23) of 4- to 7-year-old sons. In Euro–Canadian mothers, observed parenting responsiveness was associated with less lax/inconsistent parenting and fewer child behavior problems. In East Asian immigrant mothers, however, observations of greater responsiveness were not related to reports of lax/inconsistent parenting, and were associated with greater child behavior problems. Implications for the use of these parenting measures across culture groups are discussed.     

Psychopathic Sexuality: The Thin Line Between Fantasy and Reality

In two studies, we explored the relations between psychopathic traits and sexual fantasy content. In Study 1, we rated content themes in the fantasy narratives of 195 men and women recruited at a Canadian university. In Study 2, we administered a sexual fantasy questionnaire to a sample of 355 Canadian undergraduate students. In Study 1, we found that psychopathic traits predicted themes of anonymous, uncommitted, and nonromantic sexual activity after controlling for participant sex. In Study 2, we found that psychopathy added to the prediction of self‐reported engagement in unrestricted, dominant, submissive, deviant, and adventurous sexual activity, even after controlling for participant sex and level of fantasizing about that activity. Furthermore, an interaction between psychopathy and level of fantasizing was observed for unrestricted and deviant sexual behavior, such that participants who reported high levels of fantasizing about these sexual themes were more likely to engage in that behavior if they also reported high levels of psychopathic traits. These findings suggest that psychopathy is related not only to interest in particular sexual behaviors, but also to whether individuals will translate these fantasized behaviors into reality.     

Perceived Inequity: Does It Explain Burnout Among Medical Specialists?1

This study investigated, among medical specialists (N= 2,400), the association between perceived inequity in relationships at work (patients, colleagues, organization) and burnout, and the moderating role of communal orientation. Intrapersonal inequity, involving an internal standard of reference, and interpersonal inequity, taking colleagues as the standard of reference, were assessed. The adjusted response rate was 63%. Intrapersonal inequity affected all burnout dimensions: emotional exhaustion in all relationships at work, depersonalization in the relationship with patients, and reduced personal accomplishment in relationships with colleagues and the organization. Intrapersonal inequity explained more variance in burnout than did interpersonal inequity. Communal orientation did not moderate these associations. Hence, medical specialists are more vulnerable to burnout if they perceive their relationships at work to be inequitable, regardless of their tendency to help others. Organizations might, therefore, prevent burnout by creating a working environment that is supportive and appreciative.     

Using the Theory of Gender and Power to Examine Experiences of Partner Violence,Sexual Negotiation,and Risk of HIV/AIDS Among Economically Disadvantaged Women in Southern India

This article uses the Theory of Gender and Power to examine women's vulnerability to HIV/AIDS in order to: understand the vulnerability of female sex workers/poor women due to poverty and lack of educational resources; explore women's vulnerability in the context of client/partner violence, alcohol use, male partner's high-risk behaviors, and women's lack of control in their intimate relationships; and explore the role of traditional heterosexual gender norms in the outcomes of sexual negotiation. Ethnographic data were collected from 32 women and 38 men in India as part of an ongoing National Institute of Mental Health study. Results highlighted women's vulnerability to HIV/AIDS stemming from partner violence, alcohol use, poverty, dangers of sex work environments, and tacit acceptance of cultural/gender norms.     

Transgenic inhibition of neuronal calcineurin activity in the forebrain facilitates fear conditioning, but inhibits the extinction of contextual fear memories

It is unclear whether protein phosphatases, which counteract the actions of protein kinases, play a beneficial role in the formation and extinction of previously acquired fear memories. In this study, we investigated the role of the calcium/calmodulin dependent phosphatase 2B, also known as calcineurin (CaN) in the formation of contextual fear memory and extinction of previously acquired contextual fear. We used a temporally regulated transgenic approach, that allowed us to selectively inhibit neuronal CaN activity in the forebrain either during conditioning or only during extinction training leaving the conditioning undisturbed. Reducing CaN activity through the expression of a CaN inhibitor facilitated contextual fear conditioning, while it impaired the extinction of previously formed contextual fear memory. These findings give the first genetic evidence that neuronal CaN plays an opposite role in the formation of contextual fear memories and the extinction of previously formed contextual fear memories.     

Phobic tendency within the Five-Factor and HEXACO models of personality structure

Recent research has indicated that the various specific phobias are only modestly correlated with the personality dimensions of the Big Five or Five-Factor Model (B5/FFM). We tested the hypothesis that the specific phobias would be more strongly associated with the dimensions of an alternative framework, the HEXACO model of personality structure. Self-reports on the Phobic Stimuli Response Scales (PSRS) were obtained along with self- and peer reports on measures of the B5/FFM and HEXACO dimensions from a sample of 248 non-clinical participants. The PSRS variables assessing specific phobias showed stronger correlations with the HEXACO Emotionality factor than with any B5/FFM dimension, and a stronger multiple correlation with the HEXACO factors than with the B5/FFM dimensions. Findings were similar across self- and peer reports of the personality variables. The results suggest that phobic tendency can be understood in terms of normal personality variation as conceptualized in the HEXACO framework.     

Attitude Importance: Understanding the Causes and Consequences of Passionately Held Views

People care passionately about some attitudes and consider them deeply important, and they accord no particular significance to other attitudes. In the current paper, we review the state of the psychological literature on attitude importance. We consider the factors that cause people to attach importance to some attitudes but not to others, and we review the cognitive, affective, and behavioral consequences of attaching importance to an attitude. Finally, we explore several open questions regarding attitude importance, charting a course for future research in this area.
