Acculturation, communication patterns, and self-esteem among Asian and Caucasian American adolescents

This study examined level of acculturation, openness in communication with parents, peer interaction, and self-esteem in two ethnic groups-Asian and Caucasian American adolescents who grew up in the same neighborhood. The findings provide evidence of significant ethnic differences in behavioral patterns, peer networks, family contexts, and levels of self-esteem. In general, Asian adolescents expressed more difficulty discussing problems with their parents when compared to their Caucasian counterparts. Further, self-esteem was found to be significantly lower among Asians than Caucasians. Implications for the provision of mental health services are discussed.     

Cultural variations on optimistic and pessimistic bias for self versus a sibling: is there evidence for self-enhancement in the west and for self-criticism in the east when the referent group is specified?

A culturally relevant framework was used to examine variations on optimistic and pessimistic bias in Westerners and Easterners. Study 1 showed that 136 European Americans compared with 159 Japanese were more likely to predict typical positive events to occur to self than to a sibling. The opposite pattern emerged in the prediction of typical negative events. Study 2 replicated these findings on the basis of predictions for atypical events in 175 European Americans and 130 Japanese. Across both studies, within-groups analyses indicated that European Americans held an optimistic bias in the prediction of positive and negative events, whereas Japanese held a pessimistic bias for negative events. These findings are taken to offer support for presumed cultural differences in self-enhancement and self-criticism between Westerners and Easterners, respectively.     

Research note: American children's time use in after-school activities

90 Grade 4 children from upstate New York completed a "what I usually do" questionnaire, reporting on their after-school activities. Contrary to the concerns of some psychologists, there was no evidence that the children were being "hurried" out of childhood or "hot-housed" to develop academic or other excellence. The children's time was largely spent in enjoyable, self-chosen, and nonacademic activities, most often play or television viewing.     

The state of psychological assessment in Asia

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.     

Face recognition in pictures is affected by perspective transformation but not by the centre of projection

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.     

Somatosensory processing and schizophrenia liability: proprioception, exteroceptive sensitivity, and graphesthesia performance in the biological relatives of schizophrenia patients

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.     

Performance and Private Speech of Children with Attention-Deficit/Hyperactivity Disorder While Taking the Tower of Hanoi Test: Effects of Depth of Search,Diagnostic Subtype,and Methylphenidate

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.     

Reassessing the 3/4 view effect in face recognition

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.

Computerized perceptual analysis of patients with body dysmorphic disorder: a pilot study

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.
