In this qualitative study, the authors examined young adult Black American men's perceptions of treatment in mental health diversion programs. Findings included 3 themes: helpful treatment factors, cognitive dissonance, and treatment barriers. The authors explore counseling competency and advocacy considerations for judicial settings. 相似文献

Orthographic representations of words are indispensable for reading fluency. The ways in which these representations are developed and their resistance to decay are hotly debated topics. The aim of this study was to investigate the influence of semantic and phonological representations on the formation of orthographic representations in a transparent orthography. In order to achieve this objective, an experiment with three conditions was carried out. In the first condition, a group of university students were asked to repeatedly read 10 new words after semantic and phonological training, in the second condition another group of participants read the new words after phonological training, and in the third condition participants read without previous training. Finally, a follow-up session was performed to test the resistance to decay of the orthographic representations. The results showed that participants who had received semantic training formed the representations faster than participants in the other conditions, as indicated by the decrease in length effect. These results indicate the important role of previous knowledge when people face new written words. A month later these orthographic representations still remained in the lexicon of the participants. 相似文献

Echocardiographers are highly specialised, skilled practitioners who play a critical role in medical imaging diagnostics. Yet, little is known about the cognitive and perceptual attributes of experts within this domain. This study was designed to examine the role of individual differences in expertise. Specifically, the contribution of a domain general visual expertise and pattern recognition, or cue utilization. Data were collected from 42 echocardiographers and 43 naïve participants. All of the participants competed the Novel Object Memory Test (NOMT). When compared, the echocardiographers were more accurate than the naïve participants. The echocardiographers also completed an echocardiography edition of the Expert Intensive Skills Evaluation 2.0, to establish behavioral indicators of context-related cue utilization. Those with relatively higher cue utilization performed more accurately on the NOMT, controlling for exposure. These results suggest that a general perceptual ability contributes to echocardiography potential and a sensitivity to cue-based learning may contribute to expertise. 相似文献

U.S. Latino parents can face cultural stressors in the form of acculturative stress, perceived discrimination, and a negative context of reception. It stands to reason that these cultural stressors may negatively impact Latino youth's emotional well‐being and health risk behaviors by increasing parents' depressive symptoms and compromising the overall functioning of the family. To test this possibility, we analyzed data from a six‐wave longitudinal study with 302 recently immigrated (<5 years in the United States) Latino parents (74% mothers, Mage = 41.09 years) and their adolescent children (47% female, Mage = 14.51 years). Results of a cross‐lagged analysis indicated that parent cultural stress predicted greater parent depressive symptoms (and not vice versa). Both parent cultural stress and depressive symptoms, in turn, predicted lower parent‐reported family functioning, which mediated the links from parent cultural stress and depressive symptoms to youth alcohol and cigarette use. Parent cultural stress also predicted lower youth‐reported family functioning, which mediated the link from parent cultural stress to youth self‐esteem. Finally, mediation analyses indicated that parent cultural stress predicted youth alcohol use by a way of parent depressive symptoms and parent‐reported family functioning. Our findings point to parent depressive symptoms and family functioning as key mediators in the links from parent cultural stress to youth emotional well‐being and health risk behaviors. We discuss implications for research and preventive interventions. 相似文献

An early version of the computer gameStar Trek was modified to conduct behavioral research. By appropriate use of the starship’s weapon and defense systems, the player can kill enemy ships and avoid destruction. The player’s moves, as well as the time and state of the game environment when each move occurs, are recorded. The procedure tracks performance changes over time very well, and allows the dissection of performance into sequences of commands that reflect the subject’s play strategy. Computer games such asStar Trek could be the basis for experiments that bridge the gap between operant and cognitive research. 相似文献

Recently, Feferman and Hellman (and Aczel) showed how to establish the existence and categoricity of a natural number system by predicative means given the primitive notion of a finite set of individuals and given also a suitable pairing function operating on individuals. This short paper shows that this existence and categoricity result does not rely (even indirectly) on finite-set induction, thereby sustaining Feferman and Hellman's point in favor of the view that natural number induction can be derived from a very weak fragment of finite-set theory, so weak that finite-set induction is not assumed. Many basic features of finiteness fail to hold in these weak fragments, conspicuously the principle that finite sets are in one-one correspondence with a proper initial segments of a (any) natural number structure. In the last part of the paper, we propose two prima facie evident principles for finite sets that, when added to these fragments, entail this principle. 相似文献

Some authors have suggested that certain components of the event-related potentials (ERPs) reflect underlying stages in the discrimination process. Previous studies have shown that in an auditive three-choice reaction-time task the discrimination is accomplished as a two-stage process, with the more frequently occurring stimulus discriminated at an earlier point than the rarer stimulus and the subjects could be classified as fast and slow responders in function of their response to the most frequent of the three tones. We continuously recorded the electrocerebral activity (EEG) from the scalp and the electromyographic activity (EMG) from the responding muscles in a visual three-choice reaction-time task in 10 strictly right-handed subjects. EEG and EMG responses were subsequently analyzed off-line by aligning them by the onset of either the stimulus (stimulus-synchronized) or the response (response-synchronized). The results suggest that processes of visual stimuli evaluation and response execution are continuously integrated. The discrimination and response systems to visual stimuli is accomplished as a three-stage process, one to frequent tone, another for rare 1, and the last for rare 2. The subjects were classified as fast and slow responders in function of their response to the most frequent of the three tones. 相似文献

The paraventricular nucleus of the hypothalamus (PVN) has been implicated in several aspects of cardiovascular control. Stimulation of the PVN evokes changes in blood pressure and heart rate. Additionally, this brain area is connected to several limbic structures implicated in behavioral control, as well as to forebrain and brainstem structures involved in cardiovascular control. This evidence indicates that the PVN may modulate cardiovascular correlates of behavioral responses to stressful stimuli. Acute restraint is an unavoidable stressor that evokes marked and sustained cardiovascular changes, which are characterized by elevated mean arterial pressure (MAP) and an intense heart rate (HR) increase. We report on the effect of inhibition of PVN synapses on MAP and HR responses evoked by acute restraint in rats. Bilateral microinjection of the nonspecific synaptic blocker cobalt (CoCl(2), 1 mM/100 nl) into the PVN did not change the HR response or the initial peak of the MAP response to restraint stress, but reduced the area under the curve of the MAP response. Moreover, bilateral microinjection of cobalt in areas surrounding the PVN did not change the cardiovascular response to restraint. These results indicate that synapses in the PVN are involved in the neural pathway that controls blood pressure changes evoked by restraint. 相似文献
