Anxiety disorders are one of the most widespread psychological diseases in adolescence, which may lead to impairment in several areas of life and has been demonstrated a risk factor of other psychiatric disorders. One of the most widely used self-report measures to assess multiple symptoms of anxiety in youth is the Spence Children’s Anxiety Scale (SCAS). Literature suggests that anxiety symptoms vary across cultures to some extent. It has been found that individuals from collectivistic culture report higher levels of anxiety disorders than those from individualistic culture. Poland is a country whose culture was traditionally collectivistic; but now Poland is undergoing social and economic system transformation, which is taking it closer to individualistic culture. However, SCAS has never been validated in Polish samples, and thus the current study aimed (1) to assess the psychometric properties (structural validity and reliability) of SCAS in a sample of 303 Polish adolescents, (2) to examine gender differences, (3) to test the divergent validity of SCAS by relating it to the Rosenberg Self-Esteem Scale, and (4) to compare the mean levels with Chinese (collectivistic) and Italian (individualistic) samples. The results confirmed that the Polish version of SCAS showed good reliability and validity. Polish girls showed higher physical injury and generalized anxiety/overanxious symptoms than boys. Furthermore, Polish adolescents reported higher levels of anxiety than Italian youth but lower levels of anxiety than their Chinese counterparts. Implications for professionals and researchers are discussed. 相似文献

Motor imagery and action-based rehearsal were compared during motor sequence-learning by young adults (M = 25 yr., SD = 3) and aged adults (M = 63 yr., SD = 7). General accuracy of aged adults was lower than that of young adults (F(1,28) = 7.37, p =.01) even though working-memory capacity was equivalent in the two groups. Motor imagery and rehearsal by action increased accuracy in both age groups, compared with minimization of opportunity for rehearsal (F(1,28) = 30.95, p < .001), but no interaction was found with age group, which suggests that young and aged adults were equally capable of motor imagery and action-based rehearsal. It was assumed that differences in performance between young and aged participants related to the formation of mental representations of sequences and integration of new elements into these representations rather than the capacity for motor imagery or rehearsal by action per se. The current study was exploratory and involved a relatively small sample of 15 participants per age group. Caution must be taken when considering the results. 相似文献

We examined gender differences in the frequency of DSM-III-R personality disorder diagnoses and symptomatology in a sample of 225 depressed outpatients. This research partially replicates and extends one of the first studies in this area by Golomb et al. (1995). Males were significantly more likely than females to meet diagnoses for schizotypal, paranoid, narcissistic, antisocial, obsessive compulsive, and borderline personality disorder. Compared to females, males were also significantly more likely to have schizoid, schizotypal, narcissistic, antisocial, and obsessive-compulsive personality disorder symptomatology. Females did not predominate in any personality disorder symptomatology or diagnoses. A possible explanation for these findings is discussed. The results of this study challenge traditional assumptions about gender differences in the frequency of personality disorders, and confirm the need for future studies to investigate the relation between gender and personality disorders in specific Axis I samples. 相似文献

The aim of this study was to further refine the cognitive phenotype of attention-deficit/hyperactivity disorder (ADHD), with respect to the ability to sustain attention and executive functioning. Participants were 34 boys with ADHD (combined type) and 28 normal controls. The groups were closely matched for age and IQ. All participants were 12 years of age. Both groups performed a computerized sustained attention task and a response interference task. Measures related to speed, accuracy, and time on task were collected. We found that children with ADHD performed slower, less accurately, more impulsively, and with less stability than controls. Both groups produced more errors with increasing time on task, reflecting reduced vigilance. Importantly, no interaction with time on task was found. The overall pattern of results suggests that measures related to accuracy are more informative than measures related to speed of responding in refining the cognitive phenotype of ADHD. 相似文献

The orbitofrontal cortex (OBFc) has been suggested to code the motivational value of environmental stimuli and to use this information for the flexible guidance of goal-directed behavior. To examine whether information regarding reward prediction is quantitatively represented in the rat OBFc, neural activity was recorded during an olfactory discrimination “go”/“no-go” task in which five different odor stimuli were predictive for various amounts of reward or an aversive reinforcer. Neural correlates related to both actual and expected reward magnitude were observed. Responses related to reward expectation occurred during the execution of the behavioral response toward the reward site and within a waiting period prior to reinforcement delivery. About one-half of these neurons demonstrated differential firing toward the different reward sizes. These data provide new and strong evidence that reward expectancy, regardless of reward magnitude, is coded by neurons of the rat OBFc, and are indicative for representation of quantitative information concerning expected reward. Moreover, neural correlates of reward expectancy appear to be distributed across both motor and nonmotor phases of the task. 相似文献

I propose an alternative interpretation of the Crito. The arguments that are typically taken to be Socrates' primary arguments against escape are actually supplementary arguments that rely on what I call the Superiority Thesis, the thesis that the state and its citizens are members of a moral hierarchy where those below are tied by bonds of obligation to those above. I provide evidence that Socrates holds this thesis, demonstrate how it resolves a number of apparent difficulties, and show why my interpretation is preferable to competing interpretations. 相似文献

Multicultural counseling approaches variously focus on the counseling relationship. Relatively few discuss clinical techniques and strategies to any significant extent. This article explores enhancing multicultural counseling by offering an array of techniques and strategies based on addressing oppression and increasing psychological freedom. Techniques offered seek to internally free a person cognitively, affectively, and systemically using the Precursors Model of Change (Hanna, 2002). The goal is to help set a person free from oppressive, discriminatory systems and individuals. 相似文献

Event-related brain potentials (ERPs) were recorded from subjects as they attended to one diagonal of a visual display. The task was to respond only to memory set items (targets) at the attended diagonal and to ignore stimuli at the other diagonal. The probability that the display contained either an attended or an unattended target was 0.30. The spatial separation between attended and unattended stimuli was 1.6°. The ERP elicited by stimuli at the unattended diagonal contained a sequence of phasic components. The early N170 and P250 components were elicited by the onset of the display and the later components N480 and P550 by the offset of the display. The presence of masks delayed N170 and P250. The ERPs elicited by attended non-targets, in addition, contained an increased N350 (Cz, Fz) and P410 (P3a, Pz, Cz). The ERPs elicited by attended and unattended non-targets started to differ after 200 msec. This finding suggested that selection is relatively late if selection must be based on a conjunction of features (location and orientation) and if the spatial separation between attended and unattended stimuli is small. Memory-set size affected the ERPs after 250 msec. The ERPs elicited by attended stimuli contained a broadly distributed (Fz, Cz, Pz) negative endogeneous component. The amplitude of this component was related to memory-set size. Finally, the ERPs elicited by attended targets contained a large P3b (Pz, Oz) with a peak latency around 600 msec. The ERP results suggested the existence of three processing stages: (1) orienting to the attended stimuli; (2) controlled search, and (3) target decision. 相似文献
