Deviant but desirable: Group variability and evaluation of atypical group members

Two studies investigated how group variability affects reactions to atypical group members. In Study 1 (N = 65) we manipulated group variability and found that an atypical group member was evaluated more positively when the group was heterogeneous than when the group was homogeneous. In Study 2 (N = 276) we also manipulated group value and found a significant interaction whereby an atypical group member was evaluated more positively when the group was homogeneous and group members valued heterogeneity, but was evaluated more negatively when the group was heterogeneous and group members valued homogeneity. The results suggest that deviant or atypical members will not inevitably be rejected by the group, but rather that reactions to deviance are shaped and guided by the dynamic relationship between how the group is perceived by its members and their ideological beliefs about what is good for the group.     

The effects of mediated word lists on false recall and recognition

False memory effects were explored using unrelated list items (e.g., slope, reindeer, corn) that were related to mediators (e.g., ski, sleigh, flake) that all converged upon a single nonpresented critical item (CI; e.g., snow). In Experiment 1, participants completed either an initial recall test or arithmetic problems after study, followed by a final recognition test. Participants did not falsely recall CIs on the initial test; however, false alarms to CIs did occur in recognition, but only following an initial recall test. In Experiment 2, participants were instructed to guess the CI, followed by a recognition test. The results replicated Experiment 1, with an increase in CI false alarms. Experiment 3 controlled for item effects by replacing unrelated recognition items from Experiment 1 with both CIs and list items from nonpresented lists. Once again, CI false alarms were found when controlling for lexical characteristics, demonstrating that mediated false memory is not due simply to item differences.     

The interactive effects of listwide control, item-based control, and working memory capacity on Stroop performance

Hypothesized top-down and bottom-up mechanisms of control within conflict-rich environments were examined by presenting participants with a Stroop task in which specific words were usually presented in either congruent or incongruent colors. Incongruent colors were either frequently (high contingency) or infrequently (low contingency) paired with the word. These items were embedded within lists consisting of either 100% congruent or 100% incongruent filler items to create mostly congruent or mostly incongruent lists. Results indicated a significant item-specific congruency effect, which was largest for high contingency responses and within mostly congruent lists. In addition, a significant listwide congruency effect was obtained, and this interacted with working memory capacity (WMC). There were larger listwide congruency effects for low WMC individuals. Finally, the pattern of Stroop interference across lists for low WMC individuals was dependent upon the congruency of the preceding trial. These results support multiple forms of cognitive control, as well as contingency learning, as mechanisms underlying proportion congruence effects in Stroop and other conflict tasks. These findings are interpreted within Braver, Gray, and Burgess's (2007) dual mechanisms of control theory.     

Reflective Capacity: An Antidote to Structural Racism Cultivated Through Mental Health Consultation

Effecting a paradigm shift from “reproductive health” to “reproductive justice” within the perinatal field requires changes simultaneously at the levels of the individual healthcare provider and the system of care. The Infant-Parent Program at the University of California, San Francisco (UCSF) has extended its pioneering infant and early childhood mental health consultation to perinatal service systems applying an infant mental health approach to programs caring for expecting and new parents. In partnership with two nursing programs, UCSF consultants direct their efforts at supporting reflective practice capacities and use-of-self in patient–provider relationships. Both nursing programs serve vulnerable groups of expectant and new parents who grapple with challenges to health and well-being stemming from structural racism. As reflective capacities are supported within the consultation case conferences, providers spontaneously identify the need for tools to effectively address issues of race, class, and culture and to combat structural racism throughout the healthcare system. Policies and procedures that uphold structural racism cease to be tolerable to providers who bring their full selves to the work that they are trained to do. Using these nurse consultation partnerships as organizational case studies, this article describes a range of challenges that arise for providers and delineates steps to effective engagement toward reproductive justice.     

Gender Bias in Medical Implant Design and Use: A Type of Moral Aggregation Problem?

In this article, I describe how gender bias can affect the design, testing, clinical trials, regulatory approval, and clinical use of implantable devices. I argue that bad outcomes experienced by women patients are a cumulative consequence of small biases and inattention at various points of the design, testing, and regulatory process. However, specific instances of inattention and bias can be difficult to identify, and risks are difficult to predict. This means that even if systematic gender bias in implant design is an ethical issue, it is one with no clearly blameworthy player. From a practical perspective, there is no single obvious point at which to intervene. Philosophers working in other areas have explored structurally similar moral problems—sometimes referred to as “moral aggregation problems”—such as the type of environmental harm caused by small actions of many players. I describe key features of these type of problems and strategies to address them. I then draw on these to suggest an approach to gender bias in medical implant design and use.     

Getting rid of the bad ones: The relationship between group identification, deviant derogation, and identity maintenance

Two studies investigated the impact of the presentation of an undesirable group member on group stereotype judgments among participants with varying degrees of ingroup identification. In Study 1 (N = 67), identification was associated with stereotype change following presentation of an undesirable, but not a desirable, ingroup member. This relationship was mediated by evaluations of the undesirable ingroup member: the stronger the identification, the more negative the evaluation, and the greater the shift towards a more positive ingroup stereotype. In Study 2 (N = 180), identification was positively associated with ingroup stereotype ratings following presentation of an undesirable ingroup member but was negatively associated with outgroup ratings following presentation of an undesirable outgroup member. As in Study 1, the association between ingroup identification and ingroup stereotype ratings was mediated by evaluations of the undesirable ingroup member. Results are discussed in relation to the black sheep effect and identity maintenance strategies.     

The DRD4 VNTR polymorphism moderates craving after alcohol consumption.

Recent research has suggested that alterations in mesolimbic dopamine neurotransmission are central to the development and expression of craving for alcohol. Because the D4 dopamine receptor gene, variable numbers of tandem repeats (DRD4 VNTR) polymorphism putatively expresses functional differences in dopamine receptors, the present study tested whether this polymorphism influences the effects of a priming dose of alcohol on craving. Participants consumed 3 alcoholic drinks or 3 control drinks and completed measures of craving after each drink. Participants who were homozygous or heterozygous for the 7 (or longer) repeat allele were classified as DRD4 L, whereas the other participants were classified as DRD4 S. Results suggested that DRD4 L participants demonstrated significantly higher craving after consumption of alcohol as compared with the control beverage.     

What Works for the Gander Does Not Work as Well for the Goose: The Effects of Leader Behavior

This study examines the effects of leader behaviors and leader gender on employees' perceptions of support from the organization and employee commitment to the organization. Ninety-one employees completed a survey measuring leader behaviors, perceived organizational support, and organizational commitment. Results confirmed the hypothesis that a high interpersonal orientation and high task orientation had the most positive effect on employee attitudes. However, the high interpersonal orientation and high task orientation were not equally effective for both female and male leaders. Employees perceived more support from the organization when their supervisors, either female or male, used a high consideration–high initiating structure style than when they used a low consideration–low initiating structure style. On the other hand, only those employees who work for a male supervisor who is high in consideration and high in initiating structure were more committed to the organization.
