Suicidality and violence are serious public health problems. A rich literature supports the relationship between suicidality and violence, including common associations with trait anger. However, less is known about how trait anger may facilitate these behaviors. Two potential mechanisms in this relationship are emotion dysregulation and impulsivity, both of which are linked to increased anger, suicidality, and violence. We investigated anger as a common underlying factor for both suicidal and violent behavior, and emotion dysregulation and impulsivity (i.e., negative and positive urgency) as potential mediators in this relationship. Results demonstrate that trait anger was associated with both suicidal and violent behavior. Further, emotion dysregulation mediated the anger and suicidal behavior relationship whereas both negative and positive urgency mediated the anger and violent behavior relationship. Although trait anger may be a common underlying factor for both suicidal and violent behavior, the nature of these relationships seems to vary significantly. 相似文献

This study investigated differential item functioning (DIF) mechanisms in the context of differential testlet effects across subgroups. Specifically, we investigated DIF manifestations when the stochastic ordering assumption on the nuisance dimension in a testlet does not hold. DIF hypotheses were formulated analytically using a parametric marginal item response function approach and compared with empirical DIF results from a unidimensional item response theory approach. The comparisons were made in terms of type of DIF (uniform or non‐uniform) and direction (whether the focal or reference group was advantaged). In general, the DIF hypotheses were supported by the empirical results, showing the usefulness of the parametric approach in explaining DIF mechanisms. Both analytical predictions of DIF and the empirical results provide insights into conditions where a particular type of DIF becomes dominant in a specific DIF direction, which is useful for the study of DIF causes. 相似文献

When humans grasp objects, the grasps foreshadow the intended object manipulation. It has been suggested that grasps are selected that lead to medial arm postures, which facilitate movement speed and precision, during critical phases of the object manipulation. In Experiment 1, it has been tested whether grasp selections lead to medial postures during rotations of a dial. Participants twisted their arms considerably before grasping the dial, even when the upcoming dial rotation was minimal (5°). Participants neither assumed a medial posture at any point during a short rotation, nor did they assume any of the postures involved in short rotations in the opposite direction. Thus, grasp selections did not necessarily lead to specific postures at any point of the object manipulation. Experiment 2 examined the effect of various grasps on the speed of dial rotations. A medial initial grasp resulted in the fastest dial rotations for most rotation angles. Spontaneously selected grasps were more excursed than necessary to maximize dial rotation speed. This apparent overshot might be explained by participants’ sensitive to the variability of their grasps and is in line with the assumption that grasps facilitate control over the grasped object. 相似文献

In "Action and Responsibility,' Joel Feinberg pointed to an important idea to which he gave the label "the accordion effect.'
Feinberg's discussion of this idea is of interest on its own, but it is also of interest because of its interaction with his
critique, in his "Causing Voluntary Actions,' of a much discussed view of H. L. A. Hart and A. M. Honoré that Feinberg labels
the "voluntary intervention principle.' In this essay I reflect on what the accordion effect is supposed by Feinberg to be,
on differences between Feinberg's understanding of this idea and that of Donald Davidson, and on the interaction between Feinberg's
discussion of the accordion effect and his critique of the voluntary intervention principle. 相似文献

In two experiments, we explore how recent experience with particular syntactic constructions affects the strength of the structural priming observed for those constructions. The results suggest that (1) the strength of structural priming observed for double object and prepositional object constructions is affected by the relative frequency with which each construction was produced earlier in the experiment, and (2) the effects of relative frequency are not modulated by the temporal placement of the tokens of each construction within the experiment. 相似文献

The contention that basic behavioral intentions are forecasted by emotional expressions has received surprisingly little empirical
support. We introduce a behavioral task that gauges the speed with which movement of angry and fearful faces (toward or away
from an expressor's gaze) are accurately detected. In two studies we found that perceivers were faster to correctly detect
approaching anger faces (i.e., faces that moved in the direction of their own gaze). The opposite, however, was not true for
fear expressions. These findings offer evidence that, at least for anger displays, the basic behavioral intent to approach
is strongly transmitted and at very low-levels of processing, even priming congruent behavioral responses in observers. The
null results for fear faces may indicate that these signal a “freezing” response or behavioral inhibition rather than flight
per se. The results of this work are discussed in relation to contemporary theories of emotion. 相似文献

Negotiators often concede to angry partners. But what happens when they meet again? According to the spillover hypothesis, negotiators demand less from previously angry partners because they perceive them as tough. According to the retaliation hypothesis, negotiators demand more from previously angry partners because of negative impressions and a desire to get even. Experiment 1 showed that participants demanded less in later negotiations when their partner in a previous negotiation had expressed anger (rather than no emotion) and the later negotiation was with the same (rather than a different) partner. Consistent with the spillover hypothesis, this effect was mediated by inferences regarding the partner’s toughness. Experiment 2 showed that apologies reduce the negative effects of anger on impressions and desire for future interaction. Behavioral reactions were moderated by social value orientation: extending the established might/morality effect, prosocial participants responded cooperatively to an apology, whereas proselfs responded competitively. 相似文献

In two experiments, thirsty rats consumed a compound of sucrose and a non-preferred flavor. In Experiment 1, a conditioned preference was observed in the experimental group when animals were tested both thirsty and hungry, but not when they were tested just thirsty. Animals in the control group, which experienced the flavor and the sucrose unpaired, never showed a preference. Experiment 2 replicated the absence of a preference in the experimental group when rats were tested thirsty, but provided evidence that a flavor-taste association had been formed during training. After conditioning, sucrose was paired with LiCl in group Dev whereas it was unpaired in group NonDev. The sucrose devaluation produced a decrease in CS preference in group Dev, and an increment in group NonDev. Taken together, these results show that preference for a non-preferred flavor can be readily observed after pairings with the positive consequences of the US (calories or absence of an expected illness) rather than with a palatable flavor. 相似文献
