Elucidating the neural basis of joint attention in infancy promises to yield important insights into the development of language and social cognition, and directly informs developmental models of autism. We describe a new method for evaluating responding to joint attention performance in infancy that highlights the 9‐ to 10‐month period as a time interval of maximal individual differences. We then demonstrate that fractional anisotropy in the right uncinate fasciculus, a white matter fiber bundle connecting the amygdala to the ventral‐medial prefrontal cortex and anterior temporal pole, measured in 6‐month‐olds predicts individual differences in responding to joint attention at 9 months of age. The white matter microstructure of the right uncinate was not related to receptive language ability at 9 months. These findings suggest that the development of core nonverbal social communication skills in infancy is largely supported by preceding developments within right lateralized frontotemporal brain systems. 相似文献

Although animal models based on amphetamine (AMPH) or phencyclidine (PCP) treatment have been used extensively to study the neurobiological and behavioral characteristics of schizophrenia, there are conflicting reports regarding their validity in modeling the negative symptoms and cognitive deficits of schizophrenia. The present study examined how acute AMPH or PCP treatment (Experiment 1) and withdrawal from repeated AMPH treatment (Experiment 2) or PCP treatment (Experiment 3) affects social behavior and social recognition memory in male Sprague‐Dawley rats. Each subject was tested on two consecutive days. On the first day, the rats were tested four times (5 min/each) at 10‐min intervals with the same partner rat (termed “AAAA” day). One day later, the rats were tested with the previous partner in the first three sessions and with a new partner rat in the final session (termed “AAAB” day). The results show that acute AMPH treatment (1.5 mg/kg, sc) significantly reduced the time spent on social interaction, but did not affect social recognition on the first day. Acute AMPH only disrupted social recognition on the second day of drug testing. In contrast, acute PCP treatment (2.0 mg/kg, sc) had no effect on time spent on social interaction, but did significantly disrupt social recognition on both days. Withdrawal from repeated AMPH (3.0 mg/kg/day for 7 days, ip) or PCP (5.0 mg/kg/twice daily for 7 days, ip) treatment did not affect social interaction or social recognition, indicating a lack of long‐term detrimental effect of repeated AMPH or PCP treatment. These results suggest that acute AMPH treatment at a low dose (1.5 mg/kg) may be useful in modeling social withdrawal symptoms of schizophrenia, whereas acute PCP treatment at a similar dose range (2.0 mg/kg) may be useful in modeling the social cognitive deficit of schizophrenia. 相似文献

Over the last decade or so, the Internet has become a privileged media for advertisement. Despite this increase in popularity, several studies suggested that Internet users ‘avoid’ looking at ads (what is often referred to as the banner blindness phenomena). This conclusion, however, rests mostly on indirect evidence that participants do not remember the ad content. Therefore, it is unclear whether participants actually fixated the ads and how their gaze behaviour is related to memory for the ad. In the present study, we investigated whether Internet users avoid looking at ads inserted on a non‐search website using an analysis of eye movements, and if the ad content is kept in memory. Our results show that most participants fixate the ads at least once during their website visit. Moreover, even though the congruency between the ad and the editorial content had no effect on fixation duration on the ad, congruent ads were better memorised than incongruent ads. This study provides a novel and systematic method for assessing the processing and retention of advertisements during a website visit. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

This study investigated the effect of general creative personality and freedom of task choice on the social creativity of adolescents. The results indicated, first, that senior high school students scored higher than junior high school students. Second, girls scored higher than boys on originality, fluency, flexibility, appropriateness, and utility with regard to creative social problem‐solving. Third, freedom of task choice and its interaction with creative personality had significant effects on the originality, appropriateness, utility, flexibility, and fluency of social creativity. Adolescents who completed the task voluntarily scored higher on these dimensions than adolescents who completed it reluctantly and, among the voluntary adolescents, those with high and medium creative personality scored higher than those with low creative personality, whereas no such difference was found among the reluctant adolescents. Adolescents were more likely to show social creativity, and their general creative personality was more likely to be brought into effect under the freedom of task choice condition. 相似文献

Employing a survival analysis approach, this study synthesizes 3 aspects of gift literature and suggests their effects on the timing of dissolution for a romantic relationship. Products or services can be consumed for the purpose of enhancing self‐attractiveness (self‐gift), expressing love to partners (other‐gift), and announcing a relationship to the outer world (joint‐gift). Results indicate that the distribution of time until dissolution for young students’ romantic relationships is more likely to first fall and then rise. Gifts can delay the timing of dissolution, but not the probability of its final destination. For female students, self‐enhancing gifts are found to delay the timing; for male students, love‐expressive gifts speed up the timing; and for both male and female students, relationship‐announcing gifts delay the timing of dissolution. Consumers, thus, are advised to use gifts to make their relationships endure, but not to attempt to alter a poor relationship into a successful one. 相似文献

The goal of this study was to determine whether a sensorimotor or cognitive encoding is used to encode a target position and save it into iconic memory. The methodology consisted of disrupting a manual aiming movement to a memorized visual target by displacing the visual field containing the target. The nature of the encoding was inferred from the nature and the size of the errors relative to a control. The target was presented either centrally or in the right periphery. Participants moved their hand from the left to the right of fixation. Black and white vertical stripes covered the whole visual field. The visual field was either stationary throughout the trial or was displaced to the right or left at the extinction of the target or at the start of the hand movement. In the latter case, the displacement of the visual field obviously could only be taken into account by the participant during the gesture. In this condition, our hypothesis was that the aiming error would follow the direction of visual field displacement. Results showed three major effects: (1) Vision of the hand during the gesture improved the final accuracy; (2) visual field displacement produced an underestimation of the target distance only when the hand was not visible during the gesture and was always in the same direction displacement; and (3) the effect of the stationary structured visual field on aiming precision when the hand was not visible depended on the distance to the target. These results suggest that a stationary structured visual field is used to support the memory of the target position. The structured visual field is more critical when the hand is not visible and when the target appears in peripheral rather than central vision. This suggests that aiming depends on memory of the relative peripheral position of the target (allocentric reference). However, in the present task, cognitive encoding does not maintain the \"position\" of the target in memory without reference to the environment. The systematic effect of the visual field displacement on the manual aiming suggests that the role of environmental reference frames in memory for position is not well understood. Some studies, in particular those of Giesbrecht and Dixon (1999) and Glover and Dixon (2001), suggested differing roles of the environment in the retention of the target position and the control of aiming movements toward the target. The present observations contribute to understanding the mechanism involved in locating and grasping objects with the hand. 相似文献

We examined investment in body image among 48 patients diagnosed with, or at risk for malignant melanoma (MM), as well as factors hypothesized as related to increased investment, such as gender, perceived stress, mood, fatigue, and personality characteristics. Investment in body image was evaluated using the Measure of Body Apperception [Carver, C. S., Pozo-Kaderman, C., Price, A. A., Noriega, V., Harris, S. D., Derhagopian, R. S., Robinson, D. S., & Moffat, F. L. Jr. (1998). Concern about aspects of body image and adjustment to early state breast cancer. Psychosomatic Medicine, 60, 168–174]. Results showed that women reported more concerns about physical appearance than men, and patients with MM exhibited more concerns about body integrity than at-risk patients. Concerns about body integrity were related to more compulsive personality characteristics, whereas concerns about appearance were associated with more histrionic personality characteristics. Body image investment was related to poorer adjustment as indicated by heightened symptoms of fatigue and stress. This study suggests that further research on investment in body image in this patient population is warranted. 相似文献

This study investigated the cross‐cultural differences on state, trait, and social anxiety between Chinese and Caucasian American university students. Chinese students reported higher levels of social anxiety than did Caucasian american students. Correlations between trait and state anxiety were compared in light of the trait model of cross‐cultural psychology. Implications for multicultural counseling are discussed. Este estudio investigó las diferencias interculturales en cuanto a estado, rasgo y ansiedad social entre alumnos universitarios Chinos y Americanos caucásicos. Los alumnos Chinos comunicaron niveles más altos de ansiedad social que los alumnos Americanos Caucásicos. Se compararon las correlaciones entre rasgo y estado de ansiedad a la luz del modelo de rasgo de la psicología intercultural. Se discuten las implicaciones para la consejería multicultural. 相似文献

When a product's country of origin has a reputation for manufacturing high‐quality products, there may be a positive impact on product judgments. If people feel animosity toward a country as a result of its political or social policies, they may react negatively to the products it produces. These opposing effects may depend in part on the subset of country‐relevant knowledge that is accessible in memory at the time of judgment. When a product was not one on which Germany or Japan had built its reputation for manufacturing high‐quality products, associating the product with these countries increased its evaluations when industriousness had been activated as part of an unrelated experiment. However, when concepts associated with brutality had been primed, the product's country of origin had a negative effect on judgments. When the product was typical of those manufactured in the country, however, identifying its country of origin increased product evaluations regardless of whether industriousness or brutality had been primed. Thus, animosity toward a product's country of origin had an adverse effect on reactions to it only if the product was not one on which the country's reputation was based. 相似文献
