Why are well-adjusted people seen more accurately? The role of personality-behavior congruence in naturalistic social settings.

Expressive accuracy, being viewed in line with one's unique, distinctive personality traits, is emerging as an important individual difference that is strongly linked to psychological well-being. Yet little is known about what underlies expressive accuracy and its associations with well-being. The current studies examined whether personality-behavior congruence, the tendency to behave in line with one's distinctive personality trait profile, contributes to the links between well-being and expressive accuracy with new acquaintances (Unique perceiver-target pairs: Study 1: N = 437; Study 2: N = 874), by assessing congruence in naturalistic situations, including in a series of getting-acquainted interactions (Study 1; Ntargets = 77; Mdn Interactions: 7) and social situations in daily life over a 2-week period (Study 2; Ntargets = 146; MdnAssessments: 49). Across studies, we found that greater well-being predicted greater congruence, in both naturalistic social interactions and in daily life, which in turn contributed to greater expressive accuracy in getting-acquainted interactions. Overall, the current studies demonstrate the important role that congruence plays in expressive accuracy, helping to explain why well-adjusted individuals are seen more accurately.

Reassessing the good judge of personality.

Are some people truly better able to accurately perceive the personality of others? Previous research suggests that the good judge may be of little practical importance and individual differences minimal. In four large samples we assessed whether expressive accuracy (the good target) is a necessary condition for perceptive accuracy (the good judge) to emerge. As predicted from Funder's (1995) realistic accuracy model, assessments of the good judge predicted increased impression accuracy in the context of judgments of the good target. In contrast, evaluative tendencies for judges did not evidence a similar interaction; the positivity of impressions did not reliably increase as a function of how positively targets tend to be viewed. The present results suggest the good judge does indeed exist-some individuals are much better able to detect and utilize valid cues from targets-but this is only strongly evident when perceiving a good target.

Dispositional malevolence and impression formation: Dark Tetrad associations with accuracy and positivity in first impressions.

OBJECTIVE: The Dark Tetrad traits (subclinical psychopathy, narcissism, Machiavellianism, and everyday sadism) have interpersonal consequences. At present, however, how these traits are associated with the accuracy and positivity of first impressions is not well understood. The present article addresses three primary questions. First, to what extent are perceiver levels of Dark Tetrad traits associated with differing levels of perceptive accuracy? Second, to what extent are target levels of Dark Tetrad traits associated with differing levels of expressive accuracy? Finally, to what extent can Dark Tetrad traits be differentiated when examining perceptions of and by others? METHOD: In a round-robin design, undergraduate participants (N = 412) in small groups engaged in brief, naturalistic, unstructured dyadic interactions before providing impressions of their partner. RESULTS: Dark Tetrad traits were associated with being viewed and viewing others less distinctively accurately and more negatively. CONCLUSIONS: Interpersonal perceptions that included an individual scoring highly on one of the Dark Tetrad traits differed in important ways from interactions among individuals with more benevolent personalities. Notably, despite the similarities between the Dark Tetrad, traits had unique associations with interpersonal perceptions.

Knowing versus liking: Separating normative knowledge from social desirability in first impressions of personality.

There are strong differences between individuals in the tendency to view the personality of others as similar to the average person. That is, some people tend to form more normatively accurate impressions than do others. However, the process behind the formation of normatively accurate first impressions is not yet fully understood. Given that the average individual's personality is highly socially desirable (Borkenau & Zaltauskas, 2009; Wood, Gosling & Potter, 2007), individuals may achieve high normative accuracy by viewing others as similar to the average person or by viewing them in an overly socially desirable manner. The average self-reported personality profile and social desirability, despite being strongly correlated, independently and strongly predict first impressions. Further, some individuals have a more accurate understanding of the average individual's personality than do others. Perceivers with more accurate knowledge about the average individual's personality rated the personality of specific others more normatively accurately (more similar to the average person), suggesting that individual differences in normative judgments include a component of accurate knowledge regarding the average personality. In contrast, perceivers who explicitly evaluated others more positively formed more socially desirable impressions, but not more normatively accurate impressions.

Knowing More Than We Can Tell: People Are Aware of Their Biased Self-Perceptions.

There is no question that biases exist in self-perceptions of personality. To what extent do people have insight into their positive and negative self-biases? In two samples (total N = 130), people with positive biases (i.e., self-perceptions that are more positive than a reputation-based criterion measure) accurately described themselves as positively biased, and people with negative biases accurately described themselves as negatively biased. Furthermore, people were able to distinguish which traits they were more or less biased about. These findings suggest that people may know more about themselves than they initially admit. Implications for the use of self-reports and the study of self-knowledge are discussed.

The Bidimensional Impression Management Index (BIMI): measuring agentic and communal forms of impression management.

Measures of impression management have yet to incorporate two-factor models of person perception. The 2 primary factors are often labeled agency and communion. In Study 1, we assembled a new measure of impression management­the Bidimensional Impression Management Index (BIMI): It comprises 2 subscales designed specifically to tap agentic and communal content. Both subscales showed adequate alpha reliabilities under both honest and faking conditions. In Study 2, the BIMI was cross-validated in a new sample: The subscales remained relatively independent, and their reliabilities remained solid. A coherent pattern of personality correlates also supported the validities of both subscales. In Study 3, the differential sensitivity of the 2 subscales was demonstrated by manipulating the job type in simulated job applications. Implications and applications of the BIMI are discussed.

Favorable prognosis in patients with T1a/T1bN0 triple-negative breast cancers treated with multimodality therapy.

BACKGROUND: The authors evaluated the clinical characteristics, natural history, and outcomes of patients who had ≤1 cm, lymph node-negative, triple-negative breast cancer (TNBC). METHODS: After excluding patients who had received neoadjuvant therapy, 1022 patients with TNBC who underwent definitive breast surgery during 1999 to 2006 were identified from an institutional database. In total, 194 who had lymph node-negative tumors that measured ≤1 cm comprised the study population. Clinical data were abstracted, and survival outcomes were analyzed. RESULTS: The median follow-up was 73 months (range, 5-143 months). The median age at diagnosis was 55.5 years (range, 27-84 years). Tumor (T) classification was microscopic (T1mic) in 16 patients (8.2%), T1a in 49 patients (25.3%), and T1b in 129 patients (66.5%). Most tumors were poorly differentiated (n = 142; 73%), lacked lymphovascular invasion (n = 170; 87.6%), and were detected by screening (n = 134; 69%). In total, 129 patients (66.5%) underwent breast-conserving surgery, and 65 patients (33.5%) underwent mastectomy. One hundred thirteen patients (58%) received adjuvant chemotherapy, and 123 patients (63%) received whole-breast radiation. The patients who received chemotherapy had more adverse clinical and disease features (younger age, T1b tumor, poor tumor grade; all P < .05). Results from testing for the breast cancer (BRCA) susceptibility gene were available for 49 women: 19 women had BRCA1 mutations, 7 women had BRCA2 mutations, and 23 women had no mutations. For the entire group, the 5-year local recurrence-free survival rate was 95%, and the 5-year distant metastasis-free survival rate was 95%. There was no difference between patients with T1mic/T1a tumors and patients with T1b tumors in the distant recurrence rate (94.5% vs 95.5%, respectively; P = .81) or in the receipt of chemotherapy (95.9% vs 94.5%, respectively; P = .63). CONCLUSIONS: Excellent 5-year locoregional and distant control rates were achievable in patients with TNBC who had tumors ≤1.0 cm, 58% of whom received chemotherapy. These results identified a group of patients with TNBC who had favorable outcomes after early detection and multimodality treatment.

Clinical and magnetic resonance imaging findings in 92 cats with clinical signs of spinal cord disease.

Medical records of 92 cats presented with clinical signs of spinal cord disease, which had undergone magnetic resonance imaging (MRI), were reviewed. The cats were grouped into seven categories based upon the diagnosis suggested by results of MRI, cerebrospinal fluid analysis and other diagnostic procedures: neoplastic (n=25), inflammatory or infectious (n=13), traumatic (n=8), vascular (n=6), degenerative (n=5), anomalous (n=3) and those with an unremarkable MRI (n=32). There were two independent predictors of abnormal MRI findings: severity of clinical signs and presence of spinal pain. Abnormal MRI findings and speed of onset of disease were significantly associated with survival. For the 32 cats with unremarkable MRI findings, only nine died due to spinal disease and, therefore, the median survival time (MST) was not reached (lower 95% confidence interval (CI)=970 days). For the 60 cats with abnormal MRI findings, 37 died due to their disease and the MST was 138 days (95% CI: 7-807).

The effects of halothane and isoflurane on cardiovascular function in dorsally recumbent horses undergoing surgery.

OBJECTIVE: To determine the haemodynamic effects of halothane and isoflurane with spontaneous and controlled ventilation in dorsally recumbent horses undergoing elective surgery. STUDY DESIGN: Prospective randomized clinical trial. ANIMALS: Twenty-five adult horses, body mass 487 kg (range: 267-690). METHODS: Horses undergoing elective surgery in dorsal recumbency were randomly assigned to one of four treatment groups, isoflurane (I) or halothane (H) anaesthesia, each with spontaneous (SB) or controlled ventilation (IPPV). Indices of cardiac function and femoral arterial blood flow (ABF) and resistance were measured using transoesophageal and transcutaneous Doppler echocardiography, respectively. Arterial blood pressure was measured directly. RESULTS: Four horses assigned to receive isoflurane and spontaneous ventilation (SBI) required IPPV, leaving only three groups for analysis: SBH, IPPVH and IPPVI. Two horses were excluded from the halothane groups because dobutamine was infused to maintain arterial blood pressure. Cardiac index (CI) was significantly greater, and pre-ejection period (PEP) shorter, during isoflurane compared with halothane anaesthesia with both spontaneous (p = 0.04, p = 0.0006, respectively) or controlled ventilation (p = 0.04, p = 0.008, respectively). There was an association between CI and PaCO(2) (p = 0.04) such that CI increased by 0.45 L minute(-1)m(-2) for every kPa increase in PaCO(2). Femoral ABF was only significantly higher during isoflurane compared with halothane anaesthesia during IPPV (p = 0.0006). There was a significant temporal decrease in CI, but not femoral arterial flow. CONCLUSION: The previously reported superior cardiovascular function during isoflurane compared with halothane anaesthesia was maintained in horses undergoing surgery. However, in these clinical subjects, a progressive decrease in CI, which was independent of ventilatory mode, was observed with both anaesthetic agents. CLINICAL RELEVANCE: Cardiovascular function may deteriorate progressively in horses anaesthetized for brief (<2 hours) surgical procedures in dorsal recumbency. Although cardiovascular function is superior with isoflurane in dorsally recumbent horses, the need for IPPV may be greater.
