In five studies, we found that people like their names enough to unconsciously pursue consciously avoided outcomes that resemble their names. Baseball players avoid strikeouts, but players whose names begin with the strikeout-signifying letter K strike out more than others (Study 1). All students want As, but students whose names begin with letters associated with poorer performance (C and D) achieve lower grade point averages (GPAs) than do students whose names begin with A and B (Study 2), especially if they like their initials (Study 3). Because lower GPAs lead to lesser graduate schools, students whose names begin with the letters C and D attend lower-ranked law schools than students whose names begin with A and B (Study 4). Finally, in an experimental study, we manipulated congruence between participants' initials and the labels of prizes and found that participants solve fewer anagrams when a consolation prize shares their first initial than when it does not (Study 5). These findings provide striking evidence that unconsciously desiring negative name-resembling performance outcomes can insidiously undermine the more conscious pursuit of positive outcomes.  相似文献

Gamma oscillations distinguish true from false memories   总被引:1,自引:0,他引:1  
ABSTRACT— To test whether distinct patterns of electrophysiological activity prior to a response can distinguish true from false memories, we analyzed intracranial electroencephalographic recordings while 52 patients undergoing treatment for epilepsy performed a verbal free-recall task. These analyses revealed that the same pattern of gamma-band (28–100 Hz) oscillatory activity that predicts successful memory formation at item encoding—increased gamma power in the hippocampus, prefrontal cortex, and left temporal lobe—reemerges at retrieval to distinguish correct from incorrect responses. The timing of these oscillatory effects suggests that self-cued memory retrieval begins in the hippocampus and then spreads to the cortex. Thus, retrieval of true, as compared with false, memories induces a distinct pattern of gamma oscillations, possibly reflecting recollection of contextual information associated with past experience.  相似文献

ABSTRACT— Most research on perceptual–motor development has focused on changes occurring during infancy and toddlerhood. In this paper, we describe our work on the development of perceptual–motor development during late childhood and early adolescence in the context of an important applied problem: bicycling across traffic-filled roads. Specifically, we have examined the gaps between cars that children and adults accept when bicycling across intersections, using an immersive, interactive bicycling simulator. This work highlights both methodological advances in using immersive, interactive virtual environments to study perceptual–motor functioning as well as theoretical advances in understanding the problem of moving the self in relation to other moving objects. We conclude with ideas for future research and practical implications of this work.  相似文献

BACKGROUND: Recent models of emotional disorders and psychosis implicate metacognitive beliefs in the development and maintenance of psychological distress. We predicted that patients with established psychotic disorders and those meeting at risk mental state (ARMS) criteria (and, thus, at increased risk of developing psychosis) would show higher levels of metacognitive beliefs than non-patient controls. Furthermore, we predicted that patients with psychosis would show higher levels of such beliefs than the at risk group. METHOD: The Metacognitions Questionnaire was administered to 73 patients with psychotic disorders, 43 ARMS patients and 188 non-patients. RESULTS: As predicted, patients with psychotic diagnoses and those at risk scored higher on metacognitive belief dimensions than non-patients. Patients with psychosis showed higher positive metacognitive beliefs than the at risk patients, indicating a greater range of unhelpful metacognitions overall, when compared to non-patients. CONCLUSIONS: These findings are consistent with metacognitive conceptualisations of psychological disorders. The implications of these findings for clinical practice are discussed.  相似文献

The current study explored the relative ability of aggregate therapeutic alliance and cohesion variables to predict short-term group therapy outcome. Data were collected from a comparative trial of two forms of time-limited group psychotherapy for complicated grief (Piper, McCallum, Joyce, Rosie, & Ogrodniczuk, 2001). The therapeutic alliance and elements of the cohesion construct were measured from the perspectives of each patient and the group therapist at intervals during the groups; scores were aggregated across assessments. Hierarchical multiple regression analyses, adjusting for the effects of treatment approach (interpretive vs. supportive) and specific group membership, demonstrated that the patient-rated alliance was a consistent predictor of outcome. Two cohesion measures, reflecting other participants' (therapist, other members) views of the patient's "fit" with the group, also accounted for variation in outcome. Implications of the findings for research and clinical practice, and the limitations of the measurement approach taken in this study, are considered.  相似文献

Sex differences in the causes of self-reported adolescent delinquency   总被引:5,自引:0,他引:5  
Sex differences in the causes of self-reported adolescent delinquency were examined in full and half siblings born to a nationally representative sample of women in the United States. Qualitative sex differences in the genes that influence delinquency were not detected. Similarly, the proportions of variance in both aggressive and nonaggressive delinquency attributable to genetic and environmental influences did not differ significantly between girls and boys. Nonetheless, total variance in delinquency was greater among boys, and a scalar sex-differences model suggested that genetic and environmental influences on delinquency have less effect on population variation in delinquency among girls. Similarly, a test of the polygenic multiple threshold model suggested that girls require greater causal liability for the expression of delinquency than boys.  相似文献

Our pull to grasp narrative structures--including beginnings and especially endings--applies not only to the intentional craft of fictions, but to life as lived, as it is in psychoanalytic termination. Remarkable parallels, for instance, exist between thematic closure in poems and the conscious and unconscious signals of closure that develop in pretermination and accelerate in termination proper. A case illustrates this point: the slow crescendo of cues begins months before the first "pretermination dream." It is the patient's emerging awareness of greater health and freer functioning that likely gives rise to these phenomena, yet this awareness is often warded off because of the grave task of ending that it implies. Literature and psychoanalysis share concerns with how an ending is borne. Fictive closure and apocalyptic narratives allude to or imply finality (i.e., death), and lesser "endings" in daily life may not escape the specter of that linkage. But Kermode asserts that "ending" confers significance on an entire narrative and may thereby console us. Coltart links the realities of mortality and psychoanalytic termination, yet falls short of consolation. Clues to the role of beginnings (in final matters) and how they may help emerge from considering Basho's last days and poems. Nonetheless, the power of narrative has its limits in helping us bear the burden of a real ending, as of an analysis. Joining present to future, as through normal hope, or joining present to past through normal nostalgia, works toward a "bearing of the burden"--but only within the context of health achieved through the analysis.  相似文献
