The present research examines the semantic priming effects of a centrally presented single prime word to which participants were instructed to either "attend and remember" or "ignore". The prime word was followed by a central probe target on which the participants made a lexical decision task. The main variables manipulated across experiments were prime duration (50 or 100 ms), the presence or absence of a mask following the prime, and the presence (or absence) and type of distractor stimulus (random set of consonants or pseudowords) on the probe display. There was a consistent interaction between the instructions and the semantic priming effects. Relative to the "attend and remember" instruction, an "ignore" instruction produced reduced positive priming from single primes presented for 100 ms, irrespective of the presence or absence of a prime mask, and regardless of whether the probe target was presented with or without distractors. Additionally, reliable negative priming was found from ignored primes presented for briefer durations (50 ms) and immediately followed by a mask. Methodological and theoretical implications of the present findings for the extant negative priming literature are discussed.  相似文献

We examined the internal consistency reliability, convergent and divergent validity, and factor structure of the Beck Depression Inventory-II (BDI-II) in a sample of 131 Mexican American youth. The BDI-II demonstrated excellent internal consistency reliability (α=.90) and solid convergent and divergent validity with various clinical scales of the Adolescent Psychopathology Scale. Two factors, Cognitive-Somatic and Affective, emerged from an exploratory factor analysis and suggested that depressive symptomology may manifest somewhat differently in Mexican American youth. In sum, results provide tentative support for the use of the BDI-II as a measure of depression for this sample.  相似文献

The relationship between loyalty to rules and the creativity that attempts to improve those same rules was examined among Norwegian army officers deployed in international operations. Today's army officers are faced with rapidly changing work conditions and unpredictable enemies, both of which challenge and outdate rules and routines. They thus may experience that they are either guided by too few or inadequate rules, or by many rules that need to be constantly updated. Assuming that following rules is advantageous to officers, then, contrary to classical theory, it was hypothesized that officers scoring both low and high on loyalty to rules would score high on creativity. Hierarchical regression analyses revealed a significant U‐shaped relationship between loyalty to rules and creativity.  相似文献

Individuals with eating pathology, particularly those with diagnosed eating disorders, are at high risk for suicide. It is less clear whether undiagnosed eating pathology and subsyndromal eating disorders carry the same risk and, if so, what mechanisms may explain why higher levels of eating pathology yield greater risk for engaging in suicidal behaviors. The indirect relationship between disordered eating and risk for suicidal behaviors via facets of experiential avoidance was tested using a multiple‐mediator model. The model was tested using bootstrapping estimates of indirect effects in a sample of 218 noncollege student adults (Mage = 32.33, 66.1% women) with a history of suicidal attempt and/or history of nonsuicidal self‐injury (NSSI). Results revealed that disordered eating indirectly predicted risk for suicidal behaviors, distress aversion (i.e., negative attitudes or dislike of distress), and procrastination (i.e., delaying engagement with distressing activities). Results suggest that targeting experiential avoidance and helping those who have a history of engaging in suicidal behaviors and/or NSSI develop regulation strategies to use during times of distress may be of utmost importance for treatment and prevention of eating pathology.  相似文献

Although multiple studies have found that African Americans commonly experience racial discrimination, available studies have yet to examine how perceived racism might be related to suicide vulnerability in African American youth. The purpose of this study was to examine a framework for how perceived racial discrimination contributes to symptoms of depression and anxiety as well as subsequent suicide ideation and morbid ideation. Data were obtained from 722 African American youth at mean age 10.56 years (SD = 0.64); a second wave of data was obtained 2 years later. Results revealed both a direct effect and mediated effects of perceived racism on later suicide and morbid ideation. For boys and girls, the effect of perceived racism was mediated by symptoms of depression. However, the association was mediated by anxiety for girls, but not for boys in the current sample. Implications for future research and interventions are discussed.  相似文献

Reliance on self‐report limits clinicians' ability to accurately predict suicidal behavior. In this study the predictive validity of an objective measure, the death/suicide Implicit Association Test (d/sIAT), was tested among psychiatrically hospitalized veterans. Following acute stabilization, 176 participants completed the d/sIAT and traditional suicide risk assessments. Participants had similar d/sIAT scores regardless of whether they had recently attempted suicide. However, d/sIAT scores significantly predicted suicide attempts during the 6‐month follow‐up above and beyond other known risk factors for suicidal behavior (OR = 1.89; 95% CI: 1.15–3.12; based on 1SD increase). The d/sIAT may augment the accuracy of suicide risk assessment.  相似文献

Posttraumatic stress disorder (PTSD) and trauma‐related guilt are risk factors for suicidal ideation (SI) in veterans. Components of trauma‐related guilt were examined as serial mediators of the relationship between PTSD and SI. In a sample of 53 OEF/OIF/OND combat veterans, PTSD had an indirect effect on SI through a serial mediation chain of guilt cognitions, distress, and global guilt, suggesting that trauma‐related guilt via cognitions, distress, and global guilt is a pathway from PTSD to SI. Attention should be given to assessing and addressing trauma‐related guilt in veterans experiencing PTSD to prevent SI.  相似文献

A nonlinear indirect effects framework was used to investigate potential interpersonal indirect effects (i.e., perceived burden and thwarted belonging) accounting for the nonlinear relationship between body mass index (BMI) and suicide ideation. Using a sample of 338 undergraduates, results revealed a significant quadratic effect of BMI on suicide ideation via perceived burden only, which became significant as BMI fell below 18.00 kg/m2 and above 28.00 kg/m2. Our results provide novel information relevant for suicide risk screening in the context of weight‐ and health‐related interventions and provide justification for future longitudinal trials assessing suicide risk across the BMI spectrum.  相似文献
