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

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

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

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

Recent studies show that psychiatry residents express a relatively greater need for ethics curricula than their colleagues in other specialties. Such studies have been limited in their generalizability because they were conducted at one site. This study of 151 psychiatry residents at seven U.S. psychiatry programs aims to address that limitation. Residents were surveyed on issues pertaining to ethics and professionalism education. Participants were found to support such curricula during training and to value its relevance to the practice of psychiatry. Gender differences and the influence of the “hidden curriculum” on such results merit further study. 相似文献

In this study the authors investigated associations among children's observed responses to failure in an analogue entry situation, their attention deployment patterns, and skills and processes associated with self-regulation. Participants were 54 kindergarten and first-grade students who were either aggressive-rejected or low aggressive-popular based on peer nominations. Inhibitory control predicted the tendency to respond to entry failure by stopping and watching the group's activity. Baseline vagal tone and other-directed attention predicted children's tendency to change entry strategies after failure. Parent-rated attention skills moderated the relation between children's attention deployment patterns during the entry task and their responses to entry failure. Children who engaged in more other-directed attention were less likely to turn to solitary play after entry failure but only if they had high or moderate levels of attentional control. Other-directed attention was related to repeating previous entry bids without modification after entry failure but only when children had high levels of attention problems. 相似文献
