Substance use disorders and suicidal thoughts and behaviors commonly co-occur in adolescent and adult psychiatric populations and are often functionally interrelated. Although the evidence base for treatment of this population is sparse, integrated cognitive behavioral treatment (CBT) protocols, or those that rely heavily on CBT techniques, hold promise. In this paper, we provide an overview of the evidence-based literature for interventions that target suicidal behavior and substance use disorders with adults and adolescents. We then discuss the manner in which these behaviors may be functionally interrelated and offer a conceptual framework (S-O-R-C) to guide case conceptualization and treatment planning for clients with co-occurring suicidality and substance use disorders. Next, we provide a case example of a client with suicidal behavior and an alcohol use disorder and demonstrate how to apply an integrated CBT treatment protocol to this case. This case example is followed by a more general discussion about the potential advantages of integrated CBT protocols for suicidality and substance use disorders, guidelines for prioritizing treatment targets and skill selection for each individual client, and other important treatment considerations. We conclude with recommendations for future research in this area.  相似文献

Motivation has been found to enhance cognitive control, but the mechanisms by which this occurs are still poorly understood. Cued motivational incentives (e.g., monetary rewards) can modulate cognitive processing locally??that is, on a trial-by-trial basis (incentive cue effect). Recently, motivational incentives have also been found to produce more global and tonic changes in performance, as evidenced by performance benefits on nonincentive trials occurring within incentive blocks (incentive context effect). In two experiments involving incentivized cued task switching, we provide systematic evidence that the two effects are dissociable. Through behavioral, diffusion-modeling, and individual-differences analyses, we found dissociations between local and global motivational effects that were linked to specific properties of the incentive signals (i.e., timing), while also ruling out alternative interpretations (e.g., practice and speed??accuracy trade-off effects). These results provide important clues regarding the neural mechanisms by which motivation exerts both global and local influences on cognitive control.  相似文献

In this paper I look at moral debates about animal disenhancement. In particular, I propose that given the particular social institutions in which such disenhancement will operate, we ought to reject animal disenhancement. I do this by introducing the issue of animal disenhancement and presenting arguments in support of it, and showing that while these arguments are strong, they are unconvincing when we look at the full picture. Viewing animal disenhancement in a context such as high intensity food production, we see that the arguments in support of it fall short of other ethical considerations, leading me to conclude that the moral and pragmatic reasons weigh against animal disenhancement.  相似文献

The repetition effect in two-alternatiave forced choice (2AFC) tasks is a cornerstone effect in human cognition. Yet the experiments described here show that the customary benefit of repetition reverses to a cost of repetition when participants respond to an irrelevant event between targets. In Experiments 1A-1C, participants made manual 2AFC decisions to both of two consecutive targets on a trial and, on some trials, also made a manual response to an intervening event that appeared between the two targets. A repetition benefit was observed when no intervening event appeared, whereas a repetition cost was observed when a response was required to an intervening event. Experiment 2 ruled out a solely strategic interpretation of the repetition cost effect observed on intervening event trials. In Experiments 3A and 3B, an intervening event that required a simple vocal "go" response also produced a repetition cost. In Experiment 4, a repetition cost was observed when the intervening event was changed to a tone presented aurally. In Experiment 5, the repetition benefit was observed when a response was withheld to an intervening event. A dual-process interpretation of these results is discussed, with one process related to episodic integration, and the other related to processes that produce inhibition of return.  相似文献

Inhibition and the right inferior frontal cortex   总被引:27,自引:0,他引:27  
It is controversial whether different cognitive functions can be mapped to discrete regions of the prefrontal cortex (PFC). The localisationist tradition has associated one cognitive function - inhibition - by turns with dorsolateral prefrontal cortex (DLPFC), inferior frontal cortex (IFC), or orbital frontal cortex (OFC). Inhibition is postulated to be a mechanism by which PFC exerts its effects on subcortical and posterior-cortical regions to implement executive control. We review evidence concerning inhibition of responses and task-sets. Whereas neuroimaging implicates diverse PFC foci, advances in human lesion-mapping support the functional localization of such inhibition to right IFC alone. Future research should investigate the generality of this proposed inhibitory function to other task domains, and its interaction within a wider network.  相似文献

ObjectiveThe purpose of this study was to qualitatively investigate the use of self-talk during cricket batting performance through an innovative approach that allowed for within performance responses to be examined.Design and methodFive elite cricketers were interviewed alongside edited video footage of their batting innings. Semi-structured interviews were conducted to gather in-depth information and explanations about the participants' use of self-talk during each critical incident.Results and conclusionsThe findings of this study highlighted the use of instructional and motivational self-talk as a fluctuating continual narrative that enhanced skill execution, self-efficacy and focus of attention, whilst reducing performance anxiety. In particular, the athletes described the effectiveness of self-determined self-talk on their performance. Specifically, they advocated self-talk that narrowed their attentional focus and redirected their thoughts to performance-related cues during periods of declining performance.  相似文献

Abstract

Of all the research programs investigating radical life extension, cybernetic immortality is, by definition, the most ambitious. Several models fall within this category. While some include the possibility of “re-corporealizing” either as machine, biological entity, or hybrid, all models have several essentials in common. They require the ability to construct a non-biological (e.g., electronic) substrate that can model the functioning human brain, including the ability for consciousness (self-awareness) and a means for uploading into this artificial mind the contents of one's mortal life experiences. The individuals who have speculated most comprehensively on this include Ted Chu, Raymond Kurzweil, and Martine Rothblatt.11 Relevant books include: Ted Chu, Human Purpose and Transhuman Potential: A Cosmic Vision for Our Future Evolution (San Rafael, CA: Origin Press, 2014); Michio Kaku, The Future of the Mind: The Scientific Quest to Understand, Enhance, and Empower the Mind (New York: Doubleday, 2014); Ray Kurzweil, How to Create a Mind: The Secret of Human Thought Revealed (London: Penguin, 2013); Martine Rothblatt, Virtually Human: The Promise and the Peril of Digital Immortality (New York: St. Martin's Press, 2014).  相似文献

The predictive capabilities of different types of performance accomplishment information (PAI) towards self-efficacy for amateur golfers were compared as a function of skill level. Male golfers (N = 197; skilled n = 84, lesser skilled n = 113) recorded self-efficacy levels before and after competitive golf performance. Multiple regression analyses revealed that handicap was the most significant predictor of PAI towards pre-round self-efficacy for skilled golfers while practice satisfaction was the most significant predictor for lesser skilled. Handicap achievement was a significant predictor of post-round self-efficacy for both skilled and lesser skilled golfers. The findings imply athletes of varying skill level utilize different information when developing efficacy beliefs. Further study of the relationship between PAI and self-efficacy is therefore warranted in the sports domain.  相似文献

Most studies of peer support for intimate partner violence (IPV) at U.S. institutions of higher learning focused solely on male assaults on heterosexual women. As well, the bulk of this work only examined how all-male social networks perpetuate and legitimate this behavior. Using recent data from a survey administered at a large U.S. residential university, the main objective of this paper is to help fill a research gap by presenting findings on (1) how having peers who have perpetrated dating abuse and (2) peers’ encouragement to be abusive to dates contributes to IPV victimization in a campus lesbian, gay, and bisexual (LGB) community. The results show that LGB students report a higher rate of such victimization than heterosexual students and the two aforementioned types of pro-abuse peer support significantly predict victimization among both sexual orientation groups.  相似文献

In this paper we tested the automatic-effortful processing assumption of the Grouping Model. According to the Grouping Model, left-right cues are pull cues and inner-outer cues are push cues, evoking exogenous and endogenous control, respectively. In a series of four experiments we manipulated the characteristics of the cues: Onset vs. no-onset cues, spatial vs. symbolic cues, valid vs. invalid cues. The results consistently showed a dissociation between left-right and inner-outer cues. Together, the present findings provide converging evidence for the notion that left-right cues induce a fast, automatic selection of the cued responses, whereas inner-outer cues need slower, effortful processes to establish a selective preparatory set.  相似文献
