The state of psychological assessment in Asia 总被引:1,自引:0,他引:1
The collection of articles in this special section provides a much-needed examination of the state of psychological assessment in various Asian countries or societies. In particular, the contributors review and critique assessment of personality, depression and anxiety, children and adolescents, and neuropsychological evaluation. The reviews cover the use of, and research on, imported measures (Western derived) as well as indigenous measures that were developed locally. The articles make a valuable contribution toward understanding not only the state of assessment in Asia but also larger issues such as the universal applicability of assessment instruments and the cross-cultural validity of models of human behavior. 相似文献

Recognition of unfamiliar faces is susceptible to image differences caused by angular sizes subtended from the face to the camera. Research on perception of cubes suggests that apparent distortions of a shape due to large camera angle are correctable by placing the observer at the centre of projection, especially when visibility of the picture surface is low (Yang and Kubovy, 1999 Perception & Psychophysics 61 456-467). To explore the implication of this finding for face perception, observers performed recognition and matching tasks where face images with reduced visibility of picture surface were shown with observers either at the centre of projection or at other viewpoints. The results show that, unlike perception of cubes, the effect of perspective transformation on face recognition is largely unaffected by the centre of projection. Furthermore, the use of perspective cues is not affected by textured surfaces. The limitation of perspective in restoring 3-D information of faces suggests a stronger role for image-based, rather than model-based, processes in recognition of unfamiliar faces. 相似文献

In the present study, the authors examined somatosensory processing in 30 biological relatives of persons with schizophrenia (hereafter called "schizophrenia relatives"), 30 biological relatives of persons with bipolar affective disorder (psychiatric family control subjects), and 30 healthy control subjects with no family history of psychopathology. All 3 groups completed a weight discrimination task, a 2-point discrimination task, and a complex cognitive somatosensory task (i.e., graphesthesia). The schizophrenia relatives performed significantly worse on all 3 somatosensory tasks compared with both the healthy control subjects and the bipolar relatives. The healthy control subjects and psychiatric family control subjects showed no significant differences on any of the somatosensory tasks. Within the weight discrimination and 2-point discrimination tasks, schizophrenia relatives showed group differences on the d' index, the measure of sensitivity, whereas all 3 groups did not differ on lnbeta, the measure of response bias, suggesting a genuine difference in weight and touch sensitivity. The d' value of the weight discrimination task was significantly associated with both the cognitive-perceptual factor and negative symptom factor of the clinical questionnaire (e.g., Schizotypal Personality Questionnaire; SPQ), whereas the 2-point discrimination d' value and graphesthesia scores were significantly associated only with the cognitive-perceptual factor of the SPQ. Implications for the possible relation between somatosensory task performance and schizophrenia liability are discussed. 相似文献

We administered the Tower of Hanoi to demographically comparable samples of control participants (n = 34) and children with the Combined (n = 22) and Inattentive subtypes (n = 19) of Attention-Deficit/Hyperactivity Disorder (ADHD). Controls excelled over children with the Inattentive subtype, who
outperformed patients with the Combined subtype. These results replicated findings of greater executive deficits in the Combined
than in the Inattentive type of ADHD. Double-blind administration of methylphenidate improved task performance only for patients
with the Inattentive subtype. In a drug-free Baseline session, children with both subtypes of ADHD made more private verbalizations
than controls, particularly when failing puzzles. In later sessions, regardless of drug condition, the inattentive sample
exhibited a smaller increase in self-regulatory utterances under failure. In contrast, the combined sample decreased self-regulatory
verbalizations under failure only under methylphenidate. The results support some differences between the two subtypes of
ADHD in executive functioning and in their response to stimulant therapy.
Portions of these results were submitted as part of H. Theresa Chang's PhD dissertation (Chang, 2000) and Helena Kopecky's
unpublished master's research, both conducted at the University of Rochester and supervised by Rafael Klorman. 相似文献

It is generally accepted that unfamiliar faces are better recognized if presented in 3/4 view. A common interpretation of this result is that the 3/4 view represents a canonical view for faces. This article presents a critical review of this claim. Two kinds of advantage, in which a 3/4 view either generalizes better to a different view or produces better recognition in the same view, are discussed. Our analysis of the literature shows that the first effect almost invariably depended on different amounts of angular rotation that was present between learning and test views. The advantage usually vanished when angular rotation was equalized between conditions. Reports in favor of the second effect are scant and can be countered by studies reporting negative findings. To clarify this ambiguity, we conducted a recognition experiment. Subjects were trained and tested on the same three views (full-face, 3/4 and profile). The results showed no difference between the three view conditions. Our analysis of the literature, along with the new results, shows that the evidence for a 3/4 view advantage in both categories is weak at best. We suggest that a better predictor of performance for recognition in different views is the angular difference between learning and test views. For recognition in the same view, there may be a wide range of views whose effectiveness is comparable to the 3/4 view. 相似文献

Many factors influence the development of body image, one of which is the perception we have of our body. Perception can refer to actual visual input or the interpretation of vision; in other words, cognitive appraisal. The goal of this preliminary study is to determine if three groups (body dysmorphic disorder, obsessive-compulsive disorder, and a non-psychiatric control group) differed in the perception of their faces. Thirty individuals, 10 in each group, were asked to make changes to a computerized image of their face. In addition, affective and perceptual tests were administered. The groups did not differ on affective and perceptual organizational measures, although the obsessive-compulsive disorder group reported a higher level of anxiety than the body dysmorphic disorder group. Imaging software showed that facial features were modified by patients with body dysmorphic disorder and obsessive-compulsive disorder in about 50% of cases. No modifications were made in the control group. Future studies need to investigate the possible causes of these differences. 相似文献

This study attempted to address limitations in the understanding of optimism and pessimism among middle-aged adults. Specifically, a model of affectivity as a mediator of the link between outcome expectancies and psychological adjustment (life satisfaction and depressive symptoms) was presented and examined in a sample of 237 middle-aged adults. Consistent with a mediation model, results of path analyses indicated that optimism and pessimism (particularly the former) had significant direct and indirect links (by means of positive and negative affectivity) with depressive symptoms and life satisfaction. These results add to the small but growing literature identifying optimism and pessimism as important concomitants of psychological adjustment in more mature adults. 相似文献

Overexpression of and RNA interference with the CCAAT enhancer-binding protein on long-term facilitation of Aplysia sensory to motor synapses 总被引:3,自引:0,他引:3 下载免费PDF全文

In the marine mollusk Aplysia, the CCAAT/enhancer-binding protein, ApC/EBP, serves as an immediate early gene in the consolidation of long-term facilitation in the synaptic connection between the sensory and motor neurons of the gill-withdrawal reflex. To further examine the role of ApC/EBP as a molecular switch of a stable form of long-term memory, we cloned the full-length coding regions of two alternatively spliced forms, the short and long form of ApC/EBP. Overexpression of each isoform by DNA microinjection resulted in a l6-fold increase in the expression of the coinjected luciferase reporter gene driven by an ERE promoter. In addition, when we overexpressed ApC/EBP in Aplysia sensory neurons, we found that the application of a single pulse of 5-HT that normally induced only short-term facilitation now induced long-term facilitation. Conversely, when we attempted to block the synthesis of native ApC/EBP by microinjecting double-strand RNA or antisense RNA, we blocked long-term facilitation in a sequence-specific manner. These data support the idea that ApC/EBP is both necessary and sufficient to consolidate short-term memory into long-term memory. Furthermore, our results suggest that this double-strand RNA interference provides a powerful tool in the study of the genes functioning in learning and memory in Aplysia by specifically inhibiting both the constitutive and induced expression of the genes. 相似文献

This research designed three experiments to investigate the mechanism of how imagery perspective influences decision difficulty, which increases consumers' willingness to postpone making choices based on the construal level. Studies 1, 2, and 3 demonstrated that imagining from the actor's perspective lowers one's construal level, and thus leads to greater decision difficulty and willingness to postpone making choices. In comparison, those taking the observer perspective represent things at higher construal levels and have less difficulty making decisions or willingness to postpone making choices. Moreover, the derived results showed the need for cognition to moderate the relationship between imagery perspective and construal level. The findings herein extended the physical buying situation to online consumption, providing implications for marketers to further explore consumer behavior. 相似文献
