Moving Beyond Self‐Report: Implicit Associations about Death/Life Prospectively Predict Suicidal Behavior among Veterans 下载免费PDF全文
Sean M. Barnes PhD Nazanin H. Bahraini PhD Jeri E. Forster PhD Kelly A. Stearns‐Yoder BA Trisha A. Hostetter MPH Geoffrey Smith PsyD Herbert T. Nagamoto MD Matthew K. Nock PhD 《Suicide & life-threatening behavior》2017,47(1):67-77
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

People value natural environments in many different ways. In addition to the various tangible products and benefits that can be produced from a natural environment, people may also find value in their immediate experience of the environment while they are in it. This experiential value is an important aspect of quality of life for many people, but it is often not taken into account in making decisions about managing natural environments. In part, this is because the experiential value of the environment can be difficult for people to express in words. In this article, I explore how first-person methods from experiential and phenomenological psychology may help in giving voice to the ineffable experiential value of natural environments. Drawing on the work of Charles Lewis, Eugene Gendlin, and Kenneth Shapiro, I illustrate how an initially inarticulate, bodily felt sense of the experiential value of a natural environment can be explicated in a way that both expresses and carries forward the implicit sense of value. Such practices might serve as a basis for an environmental decision-making process that incorporates the hard-to-express experiential values of nature. 相似文献

Abstract A round-table discussion of the Rorschach test was held at Albany, New York, on May 8, 1937, in connection with the eighth annual meeting of the Association of Consulting Psychologists. There were 32 persons present at this conference with Dr. Bruno Klopfer, of Teachers College, Columbia University, presiding. Dr. Klopfer opened the discussion with a brief survey of the development of the Rorschach method. He presented figures to show the growth of the Rorschach Research Exchange which started with 14 subscribers in the Summer of 1936 and has now reached a total of more than one hundred subscribers in the United States and Europe. He then introduced the various speakers. 相似文献

In rapid finger tapping, occasional intertap intervals of about twice the normal length or even longer, called blockings, can be observed. Skilled rapid tapping requires that flexor and extensor activity be timed so that they coincide with certain phases of the finger movement. In the present study, the hypothesis examined was that blockings are associated with a deviation from the proper timing relations between the more proximal signals (electromyographic [EMG] bursts) and the more distal signal (position-time curve of the finger). Participants (N = 8) performed up-and-down tapping. Blockings were compared with the preceding normal tapping cycles; a temporal forward shift of the flexor burst in the time interval between two kinematic landmarks—the lifting of the finger and the reversal of the movement—was found consistently in the blockings The phase shift of the flexor burst relative to the kinematic landmarks did not develop gradually in the course of the tapping cycles that preceded the blocking but was an abrupt deviation, which suggests that blockings occur with an increased likelihood as the extremes of the normal variability of the phase relation are approached. 相似文献

Researchers often have expectations about the research outcomes in regard to inequality constraints between, e.g., group means. Consider the example of researchers who investigated the effects of inducing a negative emotional state in aggressive boys. It was expected that highly aggressive boys would, on average, score higher on aggressive responses toward other peers than moderately aggressive boys, who would in turn score higher than nonaggressive boys. In most cases, null hypothesis testing is used to evaluate such hypotheses. We show, however, that hypotheses formulated using inequality constraints between the group means are generally not evaluated properly. The wrong hypotheses are tested, i.e.. the null hypothesis that group means are equal. In this article, we propose an innovative solution to these above-mentioned issues using Bayesian model selection, which we illustrate using a case study. 相似文献

Summary Choice reaction time (RT) depends on the relationship between responses, and these dependencies are usually interpreted in terms of the advance-specification assumption. According to this assumption characteristics that are the same for the choice responses can be specified in advance of the response signal, thus allowing faster RTs. Since the advance-specification assumption is called into question by some of the available data, an alternative interpretation is suggested and formalized in terms of an accumulator model. According to the programming-interactions assumption, stimulus processing is tightly linked to response programming, so that both the possible responses are programmed as long as there is uncertainty with regard to stimulus identity. This gives rise to interactions between simultaneous processes of motor programming. Predictions of this assumption for the joint effects of signal similarity and the relationship between responses are tested and confirmed.This research was supported by grant no.

Circularly repeating patches containing sawtooth luminance gradients produce a sensation of motion when viewed in the periphery. Illusory motion is perceived in a dark-to-light direction, but only when one's gaze is directed to different locations around the stimulus, a point outside the display is fixated and the observer blinks, or when the stimulus is sequentially displayed at different locations whilst the observer fixates one point. We propose that the illusion is produced by the interaction of three factors: (i) introducing transients as a result of eye movements or blinks; (ii) differing latencies in the processing of luminance; and (iii) spatiotemporal integration of the differing luminance signals in the periphery. 相似文献

When one half of a randomly contoured pattern is displaced in one of four directions between successive exposures, Ss are capable of discriminating the direction of the displacement. Accuracy of discriminating decreases as a function of the relative displacement within the pattern, independent of the visual angle subtended by the pattern. Supplementary data suggest that Ss are unrealistically confident in the accuracy of their discrimination. The results demonstrate that identification of specific contours is not necessary for the discrimination of motion and suggest that some type of correlational process is employed by the visual system in dealing with spatially and temporally displaced patterns. 相似文献
