We are often required to interpret discordant emotional signals. Whereas equivalent cognitive paradigms cause noticeable conflict
via their behavioral and psychophysiological effects, the same may not necessarily be true for discordant emotions. Skin conductance
responses (SCRs) and heart rates (HRs) were measured during a classic Stroop task and one in which the emotions conveyed by
lexicosemantic content and prosody were congruent or incongruent. The participants’ task was to identify the emotion conveyed
by lexicosemantic content or prosody. No relationship was observed between HR and congruence. SCR was higher during incongruent
than during congruent conditions of the experimental task (as well as in the classic Stroop task), but no difference in SCR
was observed in a comparison between congruence effects during lexicosemantic emotion identification and those during prosodic
emotion identification. It is concluded that incongruence between lexicosemantic and prosodic emotion does cause notable cognitive
conflict. Functional neuroanatomic implications are discussed. 相似文献

Spoken word recognition involves brief activation of candidate words. Six experiments examined whether words semantically related to phonologically activated words would be falsely recognized. Experiments 1 and 2 involved homophones as test words; Experiment 3 used strong associates for the semantic mediation link. Experiment 4 approximated lists of "strong" converging associates. Experiment 5 expanded the real time needed for word identification by using a gating procedure during study. In Experiment 6, the goal was to create a more sensitive test by requiring participants to indicate which of two lures (mediated or control) was "most likely" to be new. Recognition errors were sensitive to separate phonetic and semantic stages in the mediated chain; however, there was little evidence of mediated false recognition, despite expectations derived from common models of spreading activation. 相似文献

Children who are diagnosed with attention deficit hyperactivity disorder (or who engage in behavior consistent with such a diagnosis) are often prescribed stimulant medications for hyperactive or inattentive behaviors. However, the mechanisms by which stimulant medications affect individuals' behavior are rarely evaluated. The purpose of the current study was to evaluate the effects of stimulant medication on response allocation when antecedents and consequences were held constant and equated. Results indicated that the presence of an amphetamine medication (Adderall) influenced response allocation across two concurrently available responses while all other stimulus conditions were held constant. 相似文献

Estes and Maddox (2002) suggested that the word frequency mirror effect in episodic recognition memory might be due to word likeness rather than to the frequency of experience with a word per se. We examined their suggestion using a factorial manipulation of frequency and neighborhood density, a measure used in lexical memory research to measure orthographic word likeness. For study with no specified task, main effects of density and frequency were in the mirror order, confirming the hypothesized mirror effect of word likeness but not its role in producing the frequency mirror effect. Lexical decision study increased the size of both mirror effects, even though the density manipulation had a negligible effect on lexical decision performance for words. Post hoc analyses showed that neither mirror effect could be explained by differences in lower order measures of word likeness (letter and bigram frequency). The joint orders of frequency and density results were mirrored across new and old conditions in accordance with attention likelihood theory (ALT), but density effects on z-ROC slope suggest that ALT may require extension to accommodate the effect of word likeness on response confidence. 相似文献

Research focused on psychological risk factors for anxiety psychopathology has led to better conceptualization of these conditions as well as pointed toward preventative interventions. Anxiety sensitivity (AS) has been well-established as an anxiety risk factor, while distress tolerance (DT) is a related construct that has received little empirical exploration within the anxiety psychopathology literature. The current investigation sought to extend the existing literature by examining both DT and the relationship between DT and AS across a number of anxiety symptom dimensions, including panic, generalized anxiety, social anxiety, and obsessive-compulsive anxiety. Participants (N = 418) completed a number of measures that assessed DT, AS, anxiety symptomatology, and negative affect. Findings indicated that DT was uniquely associated with panic, obsessive compulsive, general worry, and social anxiety symptoms, but that DT and AS were not synergistically associated with each of these symptom dimensions. These findings indicate that an inability to tolerate emotional distress is associated with an increased vulnerability to experience certain anxiety symptoms. 相似文献

Objective
Mindfulness forms the basis for multiple clinical interventions and has been induced in laboratory settings. However, few studies have examined the effects of dispositional or trait mindfulness. The purpose of this study was to investigate the relationship of trait mindfulness to laboratory stressor responding across fear-based anxiety disorder and non-anxious samples. We hypothesized that trait mindfulness would be associated with diminished stressor responding above and beyond the contribution of anxiety and depression-related variables, and to a greater extent in high anxiety than low anxiety individuals.Methods
90 participants, including 46 with anxiety disorders and 44 non-anxious controls, were assessed on hyperventilation and relaxation stressors. The relationship of trait mindfulness to stressor-related anxiety, negative affect, and duration was investigated in a hierarchical multiple regression model.Results
Trait mindfulness predicted stressor responding in over 80% of measured outcomes, and predicted to a greater extent among high anxiety individuals in 50% of outcomes.Conclusions
Trait mindfulness was associated with diminished responses to laboratory stressors in clinically anxious and non-anxious samples. Implications for emotion regulation and clinical interventions are discussed. 相似文献107.

Although research on the reasons for engaging in nonsuicidal self-injury (NSSI) has increased dramatically in the last few years, there are still many aspects of this pernicious behavior that are not well understood. The purpose of this study was to address these gaps in the literature, with a particular focus on investigating whether NSSI (a) regulates affective valence in addition to affective arousal and (b) serves a cognitive regulation function in addition to an affect regulation function. To elucidate these issues, the present study utilized a sample of 112 participants (33 controls, 39 no pain controls, 16 NSSI individuals, and 24 controls matching the affect dysregulation levels of the NSSI group), employed psychophysiological measures of affective valence (startle-alone reactivity) and quality of information processing (prepulse inhibition), and used experimental methods involving an NSSI-proxy to model the NSSI process. Results largely were consistent with predictions, supporting the hypotheses that NSSI serves to regulate cognitive processing and affective valence. On this latter point, however, the control groups also showed a decrease in negative affective valence after the NSSI-proxy. This unexpected finding is consistent with the hypothesis that opponent processes may contribute to the development of self-injurious behaviors (Joiner, 2005). Overall, the present study represents an important extension of previous laboratory NSSI studies and provides a fertile foundation for future studies aimed at understanding why people engage in NSSI. 相似文献

This article examines the evolution of the transnational orthodox Anglican movement through the lens of the Global Anglican Future Conference (GAFCON)—the movement’s most significant public expression to date. GAFCON represented the first large-scale event at which a sizable number of Anglicans (ordained and lay) from both the global North and global South gathered to galvanise an ‘orthodox’ response to the current ‘crisis’ in the Anglican Communion (a crisis precipitated by debates over the status of homosexuality). The analysis is based upon fieldwork conducted at GAFCON, a review of a range of documentary sources, and retrospective interviews with several attendees. The article argues that GAFCON constituted a key moment for the attempted framing of movement objectives for participants, other Anglicans, and outside observers, fixing a standard of orthodoxy in the final Jerusalem Declaration. While attempting to project an image of orthodox unity to outsiders, GAFCON leaders also made the negotiation of certain aspects of cultural difference central to the event’s purpose. Detailed examinations are provided of two topics (homosexuality and female ordination) that exemplify the ongoing negotiation of the boundaries of orthodoxy within the movement. The article concludes with reflections on the significance and further development of the movement. 相似文献

This study investigated developmental differences in story recall in children with attention-deficit/hyperactivity disorder
(ADHD), N = 57 (77.2% male) and their comparison peers, N = 98 (61.2% male). Children at the ages of 4–6 or 7–9 completed a free recall immediately after viewing each of two televised
stories, once in the presence of toys during viewing and once in their absence. This procedure was repeated with new stories
21 months later. Comparison children recalled more story events and showed a greater sensitivity to the thematic importance
of the story events than did children with ADHD, a pattern that remained stable over time. Older comparison children showed
a dramatic increase over time in the global coherence of their narrations, whereas the older children with ADHD showed limited
improvement over time. The implications of these findings for academic performance and the possible need for remediation are
discussed. 相似文献

A classical test for accessing the potential creativity of an individual is based on ideational fluency, where a person is asked to generate all possible uses for a familiar item like a piece of paper. In scoring the results, it is intuitive that the suggested uses should not be weighted equally. Those suggested in radically different categories are “worth more”; than those suggested within the same category only. We used information theory to derive a simple mathematical expression for a more objective measure of ideational fluency. We call this the creativity quotient (CQ). This innovative measure was examined using a small sample of participants, and is illustrated by the responses of two typical individuals from an ideational fluency task. The CQ accounts for the number of ideas (fluency), plus the number of categories (flexibility). Ongoing research will examine the independence of CQ from established measures of intelligence and personality. 相似文献
