Neuroticism (N) assesses emotional sensitivity or lability, but the construct is poorly defined and instruments used to assess
N are marred by a number of psychometric shortcomings. Neuroticism is also described in an overtly pejorative way, with items
keyed for themes reflecting low self-esteem, anxiety, and depression. The present paper presents a revised model based on
a new questionnaire entitled the Emotional Sensitivity Scale (ESS). Using an innovative scenario technique to generate items,
exploratory factor analysis of the responses of 242 participants yielded orthogonal dimensions for positive (other-oriented)
and negative (self-centered) emotional sensitivity, and the structure was confirmed using confirmatory factor analysis. Validation
studies showed that the ESS dimensions were related in systematic ways to related psychometric instruments and that, as predicted,
participants scoring high on the positive dimension were better able to recognize displayed emotions. The new scale offers
a basis for extending the research on emotional sensitivity using empirically discriminable positive and negative components. 相似文献

The primary aim of this study was to examine whether smoking to reduce negative affect was uniquely related to a range of affective vulnerability factors (e.g., anxiety sensitivity, anxious arousal, and negative affectivity) among daily smokers. Participants were 276 young adult daily smokers (124 females; M(age)=25.12, SD=10.37). Partially consistent with prediction, the motivation to smoke to reduce negative affect was significantly related to anxiety sensitivity and negative affectivity, but not anxious arousal; the observed significant effects were above and beyond other theoretically relevant factors (e.g., smoking rate, years smoked, age, gender). In contrast to prediction, habitual smoking motives demonstrated significant incremental associations with anxiety sensitivity and anxious arousal symptoms. These results suggest that there are important associations between certain smoking motives and negative affective states and that such relations are not attributable to other smoking factors (e.g., smoking rate). 相似文献

Anxiety sensitivity and intolerance of uncertainty: requisites of the fundamental fears? 总被引:1,自引:0,他引:1
Fears related to anxiety sensitivity (AS)-illness/injury sensitivity, fear of negative evaluation, and fear of pain-may have important theoretical associations with intolerance of uncertainty (IU). In separate investigations, AS and IU have been independently related to the same anxiety-related psychopathology. AS and IU seem to share a basis in fearing unknown, potentially harmful consequences; however, their inter-relationship remains uncertain. IU regarding a specific stimulus, a physical sensation for example, may result in a variety of interpretations and responses, including the catastrophic appraisals that characterize AS. The association between AS and IU was examined in a sample of 293 undergraduates. Results of confirmatory factor and correlation analyses suggest the two constructs are related, but nonetheless independent. It appears that IU may be a required component of catastrophic misappraisals while being an important construct related to fear and anxiety in its own right. Future research directions and potential applications are discussed. 相似文献

DB, the first blindsight case to be tested extensively (Weiskrantz, 1986) has demonstrated the ability to detect and discriminate a range of visual stimuli presented within his perimetrically blind visual field defect. In a temporal two alternative forced choice (2AFC) detection experiment we have investigated the limits of DB's detection ability within his field defect. Blind field performance was compared to his sighted field performance and to an age-matched control group (n=6). DB reliably detected the presence of a small (2 degrees ), low contrast (7%), 4.6c/ degrees Gabor patch with the same space-averaged luminance as the background presented within his blind field but performed at chance levels at the same eccentricity (11.3 degrees ) within his sighted field. Investigation of detection as a function of stimulus contrast revealed DB's ability to detect the presence of an 8% contrast stimulus within his blind field, compared to 12% in his sighted field. No significant difference in detection performance between DB's sighted field and the performance of six age-matched control participants suggests poor sighted field performance does not account for the results. Monocular testing also rules out differences between the eyes as an explanation, suggesting that DB demonstrates superior detection for certain stimuli within his visual field defect compared to normal vision. 相似文献

A theory of attending and reinforcement in conditional discriminations is extended to working memory in delayed matching to sample by adding terms for disruption of attending during the retention interval. Like its predecessor, the theory assumes that reinforcers and disruptors affect the independent probabilities of attending to sample and comparison stimuli in the same way as the rate of overt free-operant responding as suggested by Nevin and Grace, and that attending is translated into discriminative performance by the model of Davison and Nevin. The theory accounts for the effects of sample-stimulus discriminability and retention-interval disruption on the levels and slopes of forgetting functions, and for the diverse relations between accuracy and sensitivity to reinforcement reported in the literature. It also accounts for the effects of reinforcer probability in multiple schedules on the levels and resistance to change of forgetting functions; for the effects of reinforcer probabilities signaled within delayed-matching trials; and for the effects of reinforcer delay, sample duration, and intertrial-interval duration. The model accounts for some data that have been problematic for previous theories, and makes testably different predictions of the effects of reinforcer probabilities and disruptors on forgetting functions in multiple schedules and signaled trials. 相似文献

道德敏感性是对情境的道德含意的领悟和解释能力,是道德行为产生过程中逻辑上的初始心理成分。道德敏感性与个体对情境的自动化加工及其伴随着的直觉情绪有着密切的关系。情境的背景与特征,个体的角色卷入、道德图式以及人格特点等因素都可能影响个体的道德敏感性。道德敏感性研究已在儿童早期发展、职业伦理以及测验方法等领域取得一定成果,但其理论构建仍需进一步完善、深化,与教育干预密切相关的发展研究有待加强,研究方法也需拓展和改进 相似文献

The goal of this study was to investigate which working memory and long-term memory components predict vocabulary learning. We used a nonword learning paradigm in which 8- to 10-year-olds learned picture-nonword pairs. The nonwords varied in length (two vs. four syllables) and phonology (native sounding vs. including one Russian phoneme). Short, phonologically native nonwords were learned best, whereas learning long nonwords leveled off after a few presentation cycles. Linear structural equation analyses showed an influence of three constructs—phonological sensitivity, vocabulary knowledge, and central attentional resources (M capacity)—on nonword learning, but the extent of their contributions depended on specific characteristics of the nonwords to be learned. Phonological sensitivity predicted learning of all nonword types except short native nonwords, vocabulary predicted learning of only short native nonwords, and M capacity predicted learning of short nonwords but not long nonwords. The discussion considers three learning processes—effortful activation of phonological representations, lexical mediation, and passive associative learning—that use different cognitive resources and could be involved in learning different nonword types. 相似文献

Philosophers on all sides of the contextualism debates have had an overly narrow conception of what semantic context sensitivity
could be. They have conflated context sensitivity (dependence of truth or extension on features of context) with indexicality (dependence of content on features of context). As a result of this conflation, proponents of contextualism have taken arguments that establish
only context sensitivity to establish indexicality, while opponents of contextualism have taken arguments against indexicality
to be arguments against context sensitivity. Once these concepts are carefully pulled apart, it becomes clear that there is
conceptual space in semantic theory for nonindexical forms of contextualism that have many advantages over the usual indexical forms. 相似文献

A series of experiments was designed to examine the role of central cholinergic mechanisms in shock-induced aggression. Cholinergic blockade in the basolateral amygdala, ventral hippocampus, or dorsal hippocampus resulted in greatly reduced levels of fighting in response to footshock. However, while pain sensitivity remained unaltered in the amygdala group, both of the hippocampal groups exhibited decreased shock sensitivity. Further investigation of the amygdala revealed (1) increased fighting in response to increased cholinergic levels, (2) neuroanatomical specificity to the basolateral division of this complex, (3) that an intact basolateral amygdala is essential to the normal manifestation of shock-induced aggression, and (4) that social attraction remains unaltered by cholinergic blockade of the basolateral amygdala. Motor coordination and motor activity were not significantly affected in any treatment condition. 相似文献

Informative hypotheses are increasingly being used in psychological sciences because they adequately capture researchers’ theories and expectations. In the Bayesian framework, the evaluation of informative hypotheses often makes use of default Bayes factors such as the fractional Bayes factor. This paper approximates and adjusts the fractional Bayes factor such that it can be used to evaluate informative hypotheses in general statistical models. In the fractional Bayes factor a fraction parameter must be specified which controls the amount of information in the data used for specifying an implicit prior. The remaining fraction is used for testing the informative hypotheses. We discuss different choices of this parameter and present a scheme for setting it. Furthermore, a software package is described which computes the approximated adjusted fractional Bayes factor. Using this software package, psychological researchers can evaluate informative hypotheses by means of Bayes factors in an easy manner. Two empirical examples are used to illustrate the procedure. 相似文献
