Neural Responses to Partner Rejection Cues

ABSTRACT— Little is known about neural responses in the early automatic-stage processing of rejection cues from a partner. Event-related potentials (ERPs) offer a window to study processes that may be difficult to detect via behavioral methods. We focused on the N400 ERP component, which reflects the amount of semantic processing prompted by a target. When participants were primed by attachment-related contexts ("If I need help from my partner, my partner will be …"), rejection-related words (e.g., dismissing ) elicited greater N400 amplitudes than acceptance-related words (e.g., supporting ). Analyses of results for nonattachment primes suggest that these findings were not simply caused by target valence; the brain responds differentially to cues of partner rejection (vs. acceptance) in under 300 ms. Moreover, these early-stage neurophysiological responses were heightened or dampened as a function of individuals' adult attachment; women characterized by high anxiety and low avoidance showed the greatest N400 responses to cues of partner rejection (vs. acceptance).     

Brief cognitive-behavioral internet therapy for irritable bowel syndrome

While cognitive-behavioral therapy for IBS is quite effective, the limited availability of competent therapists and lack of access to treatment remain problematic. This paper reports on a small, randomized, controlled trial of a five week internet based cognitive-behavioral intervention for IBS with limited therapist feedback via e-mail. Fifty-four IBS patients were recruited via the internet and randomly assigned to either immediate treatment or a wait-list control group. Thirty-one subjects completed the post-treatment assessment. 77% of treatment completers also completed a 3-month follow-up assessment. Treatment completers experienced statistically and clinically significant declines in IBS symptoms and improvements in quality of life. Those gains were substantially maintained at follow-up. Treatment efficacy was partially mediated by reductions in the tendency to catastrophize the social and occupational implications of symptoms, suggesting that catastrophizing may be an important target for treatment.     

Sociodemographic Variations in Self-Reported Racism in a Community Sample of Blacks and Latino(a)s

This study investigated dimensions of socioeconomic status (SES) and self-reported racism among a convenience sample of 418 U.S.-born, Black and Latino(a) urban-dwelling adults. Predictors included indexes of individual and neighborhood SES. Self-reported racism was assessed with the Perceived Ethnic Discrimination Questionnaire–Community Version. Individuals at all levels of SES report racism, but the type of exposure varies by SES. Lower levels of SES predict higher levels of lifetime exposure to race-related stigmatization and threat/harassment, and more past-week discrimination. In contrast, higher levels of SES predict greater workplace discrimination. The findings highlight the importance of considering the complex ways in which SES and racism, 2 contributors to racial disparities in health, overlap and diverge.     

To Be a Donor or Not to Be? Applying an Extended Theory of Planned Behavior to Predict Posthumous Organ Donation Intentions

Using a theory of planned behavior (TPB) perspective, individual intentions to register and discuss the decision of organ donation with significant others were examined. In addition to standard TPB variables (attitude, subjective norm, and perceived behavioral control [PBC]), self-identity and moral norm were incorporated into the TPB as predictors. Australian university students ( N  = 303) completed a survey comprising standard and additional TPB constructs. Separate analyses were conducted for both registered and nonregistered participants. In general, results provide support for the extended TPB model in predicting intentions to register and discuss the donation decision, with the exceptions that self-identity did not predict discussion intentions for either registered or nonregistered participants, and PBC did not predict discussion intentions for nonregistered participants.     

Measuring Theodicy: Individual Differences in the Perception of Divine Intervention

The attribution of control to God may have particularly interesting psychological properties. Theodicy refers to the perception of God controlling history—even the minutiae of daily events. The current study examines the psychometric properties of a new instrument, the Theodicy Scale. Results support the reliability of the brief scale when administered to college students, and some evidence is provided suggesting construct validation. Theodicy appears to represent a unitary construct and scores vary independent of social desirability bias. The absence of a relationship between Theodicy scores and simulated medical advice raises questions to be addressed in future research.     

Toddlers’ referential understanding of pictures

Pictures are referential in that they can represent objects in the real world. Here we explore the emergence of understanding of the referential potential of pictures during the second year of life. In Study 1, 15-, 18-, and 24-month-olds learned a word for a picture of a novel object (e.g., “blicket”) in the context of a picture book interaction. Later they were presented with the picture of a blicket along with the real object it depicted and asked to indicate the blicket. Many of the 24-, 18-, and even 15-month-olds indicated the real object as an instance of a blicket, consistent with an understanding of the referential relation between pictures and objects. In Study 2, children were tested with an exemplar object that differed in color from the depicted object to determine whether they would extend the label they had learned for the depicted object to a slightly different category member. The 15-, 18-, and 24-month-old participants failed to make a consistent referential response. The results are discussed in terms of whether pictorial understanding at this age is associative or symbolic.     

Young Australian Women’s Aspirations for Work and Family: Individual and Sociocultural Differences

The arguments underlying Hakim’s Lifestyle Preference Theory have initiated debate over the importance of individual preferences, versus social and structural constraints, in women’s work and family patterns. This paper investigates the role of sociocultural factors in lifestyle preferences. A total of 6,929 Australian women, aged 25–30 years, from the Australian Longitudinal Study on Women’s Health (ALSWH), were categorised into Hakim’s Lifestyle Preference Groups, based on their aspirations for work and family. Rather than cutting across social groups, membership into Lifestyle Preference Groups was significantly related to sociodemographic variables. Further, the findings suggested that Hakim’s definition of ‘adaptive’ women may be too limited to capture the variability of the large number of young Australian women aspiring to combine paid work and family.     

Maternal and Paternal Parenting Styles in Adolescents: Associations with Self-Esteem,Depression and Life-Satisfaction

Our study examined variations in adolescent adjustment as a function of maternal and paternal parenting styles. Participants included 272 students in grades 9 and 11 from a public high school in a metropolitan area of the Northeastern US. Participants completed measures of maternal and paternal parenting styles and indices of psychological adjustment. Authoritative mothering was found to relate to higher self-esteem and life-satisfaction and to lower depression. Paternal parenting styles was also related to psychological adjustment, however, although the advantage of authoritative mothering over permissive mothering was evident for all outcomes assessed, for paternal styles the advantage was less defined and only evident for depression. Our study highlights the importance of examining process-oriented agents as part of the broader interest in well-being variations in adolescents.     

Role of matrix metalloproteinases in the acquisition and reconsolidation of cocaine-induced conditioned place preference

Persistent drug seeking/taking behavior involves the consolidation of memory. With each drug use, the memory may be reactivated and reconsolidated to maintain the original memory. During reactivation, the memory may become labile and susceptible to disruption; thus, molecules involved in plasticity should influence acquisition and/or reconsolidation. Recently, matrix metalloproteinases (MMPs) have been shown to influence neuronal plasticity, presumably by their regulation of extracellular matrix (ECM) molecules involved in synaptic reorganization during learning. We hypothesized that inhibition of MMP activity would impair the acquisition and/or reconsolidation of cocaine-conditioned place preference (CPP) in rats. Intracerebral ventricular (i.c.v.) microinjection of a broad spectrum MMP inhibitor, FN-439, prior to cocaine training suppressed acquisition of CPP and attenuated cocaine-primed reinstatement in extinguished animals. In a separate experiment, the cocaine memory was reactivated on two consecutive days with a cocaine priming injection. On these two days, artificial cerebral spinal fluid (aCSF) or FN-439 was administered either 30 min prior to or 1 min after cocaine-primed reinstatement sessions. Infusion of FN-439 partially impaired retrieval of the cocaine-associated context when given 30 min prior to cocaine. In both groups, however, FN-439 suppressed reinstatement compared with controls on the third consecutive test for cocaine-primed reinstatement, when no FN-439 was given. Control experiments demonstrated that two injections of FN-439 + cocaine given in the home cage, or of FN-439 + saline priming injections in the CPP chambers did not disrupt subsequent cocaine-primed reinstatement. These results show for the first time that (1) MMPs play a critical role in acquisition and reconsolidation of cocaine-induced CPP, and (2) rats demonstrate apparent disruption of reconsolidation by an MMP inhibitor after extinction and while they are under the influence of cocaine during reinstatement.     

The Perverse Effects of Competition on Scientists’ Work and Relationships

Competition among scientists for funding, positions and prestige, among other things, is often seen as a salutary driving force in U.S. science. Its effects on scientists, their work and their relationships are seldom considered. Focus-group discussions with 51 mid- and early-career scientists, on which this study is based, reveal a dark side of competition in science. According to these scientists, competition contributes to strategic game-playing in science, a decline in free and open sharing of information and methods, sabotage of others’ ability to use one’s work, interference with peer-review processes, deformation of relationships, and careless or questionable research conduct. When competition is pervasive, such effects may jeopardize the progress, efficiency and integrity of science.
