Defensive reactions of “wild-type” and “Domesticated” wild rats to approach and contact by a threat stimulus

Selective breeding of wild rats over many generations on the basis of low or high defensive threat and attack to human approach and contact has produced highly polarized “domesticated” and “wild-type” animals. Because the selection procedure selectively involves these two defense patterns, and these clearly differ in the two groups, it is of interest to determine if other, nonselected, defensive behaviors to threat stimuli also change. “Domesticated” and “wild-type” rats of the thirty-fifth generation were run in a fear defense test battery (F/DTB) to systematically evaluate defensive behaviors to a variety of present threat stimuli. “Domesticated” rats showed reduced avoidance and slower flight speed to an approaching experimenter, reduced jump/startle response to handelap and dorsal contact, less vocalization and boxing to vibrissae stimulation or to an anesthetized conspecific, and reduced defensiveness to an attempted pickup by the experimenter. These results indicate that selective bi-directional breeding for defensive threat and attack to human approach and contact produces group differences in a variety of defensive behaviors, and in defensiveness to stimuli other than those on which the selection was based. © 1994 Wiley-Liss, Inc.     

Motivation and anxiety for dental treatment and dental attendance: The roles of the locus of causality personality and treatment styles

The purpose of the present study was to test a self-determination theory model with the following hypotheses: (1) Patients’ autonomous causality personality orientation and oral health care professionals’ autonomy-supportive treatment styles, as perceived by patients, would both be positively indirectly associated with dental attendance through patients’ autonomous motivation for dental treatment. (2) Patients’ controlled causality personality orientation and oral health care professionals’ controlling treatment styles, as perceived by patients, would both be positively indirectly associated with avoidance of making a dental clinic appointment through patients’ anxiety for dental treatment. A sample size of about 200 patients was estimated to be acceptable in detecting moderate effect sizes (independent variables: 5–6; power: .80; p < .05). Student patients (N = 226) responded to a survey with validated questionnaires. Using LISREL, both hypotheses were supported. In addition, patients’ perception of a controlling treatment style moderated the controlled personality—dental anxiety relation, so that a lower controlling treatment style mitigated dental anxiety substantially among patients with a high control orientation. Effect sizes were moderate to large. Analyses (Z-scores) also revealed that the autonomous personality is more strongly linked to situational autonomous motivation than situational autonomy support, whereas a controlled personality and a perceived controlling treatment style are equally and significantly associated to dental anxiety. Both patient personalities and oral health care professionals’ treatment styles are substantially linked to autonomous motivation and anxiety for dental treatment, which are relatively strongly associated with dental attendance and avoiding dental clinic appointments, respectively.     

Borderline personality disorder,complex trauma,and problems with self and identity: A social-communicative approach

Borderline personality disorder (BPD) is a relatively highly prevalent psychiatric disorder that is associated with very high personal and socioeconomic costs. This paper provides a state-of-the-art review of the relationship between complex trauma and key features of BPD, with a focus on problems with self-coherence and self-continuity. We first review evidence for the high prevalence of complex trauma in BPD patients. This is followed by a discussion of emerging knowledge concerning the biobehavioral mechanisms involved in problems related to self and identity in BPD. We emphasize three biobehavioral systems that are affected by complex trauma and are centrally implicated in identify diffusion in BPD: the attachment system, mentalizing or social cognition, and the capacity for epistemic trust—that is, an openness to the reception of social communication that is personally relevant and of generalizable significance. We formulate a new approach to personality and severe personality disorders, and to problems with self and identity in these disorders, rooted in a social-communicative understanding of the foundations of selfhood. We also discuss how extant evidence-based treatments address the above-mentioned biobehavioral systems involved in identity diffusion in BPD and related disorders, and the supporting evidence. We close the paper with recommendations for future research.

Promoting the underestimated: A vignette study on the importance of the need for affiliation to successful leadership

Research on the relationship of implicit motives and effective leadership emphasises the importance of a socialised need for power, whereas high levels of the need for affiliation are assumed to thwart a leader’s success. In our study, we experimentally analysed the impact of leaders’ socialised need for power and their need for affiliation on perceptions of transformational leadership and various success indicators. Using paper-people vignettes, we contrasted leaders characterised by either motive with those concerned with personalised power or achievement. Results based on N?=?80 employees show that leaders high in socialised power were rated more successful and elicited more identification and organisational citizenship behaviour (OCB) in followers, and that in most cases this effect was mediated by perceptions of transformational leadership. For all outcomes but OCB, findings remained unchanged when affiliation-motivated leaders were considered. Exploratory analyses contrasting socialised power-motivated and affiliation-motivated leaders show that with regard to attitudinal outcomes affiliation-motivated leaders were, on average, as effective as socialised power-motivated ones.

     

Risk assessment in sentencing and plea bargaining: The roles of prosecutors and defense attorneys

Research on risk assessment in sentencing has focused heavily on the role of judges. Ignoring the role of other courtroom actors in the sentencing process, however, leaves unexamined the potentially significant effects on judicial decision making of arguments made by prosecutors and defense attorneys at sentencing hearings. Unduly focusing on judges also overlooks the vast majority of sentences arrived at through negotiated guilty pleas. We explored the extent to which considerations of risk are made among prosecutors and defense attorneys when advocating for given sentences in open court or during plea negotiations. We surveyed all prosecutors and defense attorneys in 14 judicial circuits in Virginia and found that most prosecutors and defense attorneys at least “sometimes” explicitly invoked actuarial risk estimates both at sentencing hearings and during plea negotiations. However, defense attorneys were much more likely than prosecutors to be averse to the use of risk assessment in either form of case disposition.     

Relationship science and the credibility revolution: An introduction to the first part of the special issue

In the past 10 years, the field of relationship science—like many other fields—has been exposed to dramatic changes in how scientists approach the research process. Relationship science has been at the forefront of many recent changes in the field, whether it be high profile replication attempts or broader discussions about how to increase rigor and reproducibility. A major goal of this special issue was to provide an opportunity for relationship scientists to engage with these issues and reforms. The first four articles in this special issue represent a sampling of different approaches relationship researchers have used to enhance the credibility of their work.
