Anxiety and depression are often associated with attention control deficits, but few studies have explored whether neuroticism can account for these links. In the present study, undergraduate students (n=146) completed self-report measures of neuroticism, worry, anxious arousal, and anhedonic depression and also completed a visual attention task in which they were asked to identify a red target letter embedded within a rapid sequence of items. Neuroticism was associated with detection of the target when it was preceded by a distracter with which it shared a feature in common (a green letter). Specifically, these distracters produced longer attentional blinks in individuals with elevated levels of neuroticism. In contrast, target detection was not significantly associated with worry, anxious arousal, or anhedonic depression. We discuss the implications of this link between neuroticism and attention for cognitive models of emotional distress and disorders.  相似文献

Depression is thought to be characterised by impaired emotion regulation, although the mechanisms of that regulation are not yet well understood. The present study examined trait, spontaneous and instructed emotion regulation in dysphoric (n = 66) and non-dysphoric (n = 86) participants. Participants were randomly assigned to use reappraisal while watching a sadness-inducing film clip (instructed emotion regulation condition) or were not given specific viewing instructions (spontaneous emotion regulation condition). Participants also completed trait measures of emotion regulation. Dysphoric individuals reported greater spontaneous use of rumination and suppression than non-dysphoric individuals, and these strategies were associated with greater negative emotional reactivity to the sadness-inducing film clip. Both participant groups were able to effectively use reappraisal when instructed to do so. The clinical implications of these findings and future research directions are discussed.  相似文献

Many neuroscientists view prediction as one of the core brain functions, especially on account of its support of fast movements in complex environments. This leads to the natural question whether predictive knowledge forms the cornerstone of our common-sense understanding of the world. However, there is little consensus as to the exact nature of predictive information and processes, or of the neural mechanisms that realize them. This paper compares procedural versus declarative notions of prediction, examines how the brain appears to carry out predictive functions, and discusses to what degree, and at what level, these neural mechanisms support cognitive incrementalism: the notion that high-level cognition stems from sensorimotor behavior.  相似文献

Causal theories of measurement view test items as effects of a common cause. Behavior domain theories view test item responses as behaviors sampled from a common domain. A domain score is a composite score over this domain. The question arises whether latent variables can simultaneously constitute domain scores and common causes of item scores. One argument to the contrary holds that behavior domain theory offers more effective guidance for item construction than a causal theory of measurement. A second argument appeals to the apparent circularity of taking a domain score, which is defined in terms of a domain of behaviors, as a cause of those behaviors. Both arguments require qualification and behavior domain theory seems to rely on implicit causal relationships in two respects. Three strategies permit reconciliation of the two theories: One can take a causal structure as providing the basis for a homogeneous domain. One can construct a homogeneous domain and then investigate whether a causal structure explains the homogeneity. Or, one can take the domain score as linked to an existing attribute constrained by indirect measurement.  相似文献

Posttraumatic Stress Disorder (PTSD) is associated with difficulties in intimate relationships, with most prior research examining associations with continuous, single-dimension, and often-unstandardized measures of general relationship quality or aggression. Standardized, well-normed assessments that include multiple couple problem areas could provide more precise information about the presence and specific nature of clinically significant concerns in patient care settings. This investigation aimed to replicate findings regarding increased difficulties in relationship functioning among Operations Enduring and Iraqi Freedom Veterans with PTSD and their romantic partners, specifically using a standardized assessment that permits identification of cases of clinically significant general couple distress and difficulties across multiple problem areas. We compared 32 male Veterans with PTSD and 33 without PTSD, and their romantic partners on reports of several problem areas using the revised Marital Satisfaction Inventory (MSI-R). All participants underwent structured diagnostic interviewing. PTSD couples reported clinically significant levels of relationship distress several times more frequently than comparison couples, both for general distress and across all specific problem areas (e.g., aggressive behavior, quality of leisure time together, sexual functioning, conflicts about finances and child rearing). The most notable problem areas for PTSD couples were affective and problem-solving communication. These results replicate associations of PTSD with general couple discord and multiple specific areas of couple difficulties and extend them by documenting the clinical severity of these problems. Mental health providers may consider incorporating standardized couple assessments into their evaluations of Veterans’ functioning. Couple therapies may consider using such measures to prioritize targets for treatment.  相似文献

The Institute of Medicine has stressed the need for evaluations of evidence-based treatments (EBTs) for posttraumatic stress disorder (PTSD) among active duty service members (AD) using a variety of evaluation approaches (Institute of Medicine, 2012). The current study examined the clinical files of 134 service members who completed treatment for PTSD using either prolonged exposure (PE) or cognitive processing therapy at an outpatient clinic. At the completion of each session, therapists made a clinical rating as to whether or not the session was protocol adherent. The total number of treatment sessions and the proportion of sessions rated as being protocol adherent were calculated. Multi-level models estimated the change in patient PTSD and other psychological symptoms over time as a function of clinician-rated protocol adherence and total number of sessions. Approximately 65% of clinic encounters were rated by therapists as being protocol adherent. Significant reductions in PTSD and psychological symptoms were associated with protocol adherence, and this was particularly true for patients who began treatment above clinical thresholds for both PTSD and other psychological symptoms. However, as the number of sessions increased, the impact of protocol adherence was attenuated. Patient characteristics, including gender, ethnicity, and co-morbidity for other psychiatric disorders were not related to symptom change trajectories over time. These findings suggest that protocol adherence and efficiency in delivery of EBTs for the treatment of PTSD with AD is critical.  相似文献

One can distinguish statistical models used in causal modeling from the causal interpretations that align them with substantive hypotheses. Causal modeling typically assumes an efficient causal interpretation of the statistical model. Causal modeling can also make use of mereological causal interpretations in which the state of the parts determines the state of the whole. This interpretation shares several properties with efficient causal interpretations but also differs in terms of other important properties. The availability of alternative causal interpretations of the same statistical models has implications for hypothesis specification, research design, causal inference, data analysis, and the interpretation of research results.  相似文献

According to interdependence theory, interpersonal situations that vary in their surface characteristics can be united by similarities in their underlying structure. Likewise, factor analytic approaches to personality combine many traits into a small number of factors. In the current research, we use interdependence theory and existing factor analyses of personality traits to measure people's lay theories about the ways traits and situations interact. We predict that traits representative of honesty–humility/virtue will be rated as more relevant to situations with non‐correspondent outcomes (a gain in one person's outcomes is associated with a loss in the other person's outcomes) than to situations with correspondent outcomes (a gain in one person's outcomes is associated with a gain in the other person's outcomes). Conversely, we predict that traits representative of agreeableness will be rated as more relevant to situations with correspondent outcomes than to situations with non‐correspondent outcomes. An experiment found the expected trait X situation interaction revealing that subjects expect certain types of traits to be most relevant to specific types of situations.

At times, an individual in modernity can feel dehumanised by work, by administration, by technology, and by political power. This experience of being dehumanised can take the individual to an existential awareness of the priority of existence over essence. But what does this existential experience mean? Are there ways in which this experience can reconnect the individual to her being human, or to her being part of humanity? Any such reconnection is further complicated by the suspicion that universal presuppositions concerning ‘humanity’ or ‘human being’ or ‘humanism’ carry pretensions of imperialist grandeur that must be challenged. How, then, might one proceed to connect existential vertigo with a culture of humanism that, while resisting such pretensions, nevertheless can find meaning for the dehumanised individual? In what follows I argue that a concept of modern metaphysics, with an aporetic (Hegelian) logic of subjective experience, can carry this reconnection of the I and the We, offering meaning not in the resolution of their opposition, but in learning that the meaning of their opposition, and the meaning of humanity, is learning, is our education. I argue that it is only within modern educational metaphysics that humanity and the individual Know Thyself.  相似文献
