Recognition memory can be supported by both the assessment of the familiarity of an item and by the recollection of the context in which an item was encountered. The neural substrates of these memory processes are controversial. To address these issues we applied repetitive transcranial magnetic stimulation (rTMS) over the right and left dorsolateral prefrontal cortex (DLPFC) of healthy subjects performing a remember/know task. rTMS disrupted familiarity judgments when applied before encoding of stimuli over both right and left DLPFC. rTMS disrupted recollection when applied before encoding of stimuli over the right DLPFC. These findings suggest that the DLPFC plays a critical role in recognition memory based on familiarity as well as recollection. 相似文献

Spatial knowledge, necessary for efficient navigation, comprises route knowledge (memory of the landmarks along a route) and survey knowledge (map-like). Available data on the retention in humans of spatial knowledge show that this does not decline systematically over months or years. Here, two groups of participants elaborated route and survey knowledge during navigation in a complex virtual environment before performing route and survey tasks. Both groups were tested 5 minutes after learning and 3 months later, while one group was also tested 1 week and 1 month later (repeated testing). Performance was similar in both groups on the first testing session, remained stable in the repeated tested group, but decreased in the non-repeated tested group, especially on route tasks. These results are the first to reveal a substantial and selective decline of spatial knowledge, occurring only if there is no possibility of reactivating knowledge along repeated testing. 相似文献

We described a 56-years-old man with a diagnosis of "non-fluent primary progressive aphasia" (NfPPA). An accurate neuropsychological, neurological and neuroimaging evaluation was performed in order to assess clinical and behavioural features of the patient. From a neuropsychological point of view, the patient showed a typical cognitive profile of subjects affected by NfPPA: a prominent language deficit, associated with impairments in several cognitive domains after three years from the onset of the symptomatology. The most intriguing feature is that SPECT revealed hypoperfusion in the right frontal cortex, albeit the patient is right-handed. This unexpected finding shows that NfPPA may arise not only from cortical abnormalities in the language-dominant left hemisphere, but also from right hemisphere involvement in a right hander (crossed aphasia). 相似文献

Psychogenic amnesia is a complex disorder characterised by a wide variety of symptoms. Consequently, in a number of cases it is difficult distinguish it from organic memory impairment. The present study reports a new case of global psychogenic amnesia compared with two patients with amnesia underlain by organic brain damage. Our aim was to identify features useful for distinguishing between psychogenic and organic forms of memory impairment. The findings show the usefulness of a multidimensional evaluation of clinical, neuroradiological, neuropsychological and psychopathological aspects, to provide convergent findings useful for differentiating the two forms of memory disorder. 相似文献

This study was designed to explore selected personality features of patients that are associated with clinicians' judgments about whom to refer to dynamic group psychotherapy versus individual therapy. Results suggested that an aspect of patients' adult attachment style, namely level of confidence and level of hostility, may have influenced the clinicians' judgments and decision making about treatment referrals. 相似文献

This article presents evidence for the validity of the circumplex model to represent how parents and teachers organize interpersonal attributes in children. Study 1 showed that the ratings of adults using interpersonal adjectives to describe 4- to 10-year-old children conformed to a circumplex structure. Eight scales-labeled Interpersonal Adjective Scales for Children (IAS-C)-were developed to represent the circular sequence of children's interpersonal attributes, as ordered around the reference axes of Extraversion and Social Appropriateness. The continuum of interpersonal variables substantially corresponded to Schaefer's model for social and emotional behavior, as follows: Warm-Agreeable, Sociable-Cheerful, Exuberant-Dominant, Impulsive-Aggressive, Egocentric-Irritable, Fearful-Insecure, Shy-Silent, and Mild-Placid. Study 2 demonstrated cross-validity for the IAS-C and how they are related to Big Five measures. Study 3 used data from Studies 1 and 2 in a confirmatory approach to test the circumplex IAS-C structure. Findings are discussed in relation to the adult circumplex model and suggest that the child circumplex has distinctive features that must be kept in due consideration when attempting to assess interpersonal qualities in children validly. 相似文献

Internet addiction disorder: an Italian study. 总被引:2,自引:0,他引:2

The Italian version of the Young's Internet Addiction Test (IAT) was administered online to a sample of Italian chatters (n = 236) who were different in terms of gender, age, and occupation. Results revealed that young users are more at-risk subjects for Internet addiction than adults, perceiving a compromised social and individual quality of their life that led them to make a compensatory usage of the Internet. Similarly, employed users perceive their social and individual quality of life as more compromised by the Internet than students. Moreover, subjects who declared spending much time online obtained IAT scores higher than others in all the IAT subscales. Finally, nightly users are more at-risk subjects for developing an Internet addiction disorder, diminishing their individual quality of life and disabling their time control. 相似文献

This study examined the relations between acculturative stress and psychological functioning, as well as the protective role of social support and coping style, in a sample of 148 Mexican American college students (67% female, 33% male; mean age = 23.05 years, SD = 3.33). In bivariate analyses, acculturative stress was associated with higher levels of anxiety and depressive symptoms. Moreover, active coping was associated with better adjustment (lower depression), whereas avoidant coping predicted poorer adjustment (higher levels of depression and anxiety). Tests of interaction effects indicated that parental support and active coping buffered the effects of high acculturative stress on anxiety symptoms and depressive symptoms. In addition, peer support moderated the relation between acculturative stress and anxiety symptoms. Implications for reducing the effects of acculturative stress among Mexican American college students are discussed. 相似文献

The present study assessed the possibility of promoting pre-ambulatory foot–leg movements in children with multiple disabilities
by motivating their action through contingent stimulation combined with a support device. Two children aged 10 and 8 years
participated. Microswitch technology (i.e., pressure sensors under the shoes or optic sensors at the front–inner side of the
shoes) served for detecting the foot–leg movements and providing contingent stimulation on their occurrence. Sensor activation
produced 5 s of stimulation during intervention. Data showed that both children had significant increases in foot–leg movements
during the intervention phases. Implications of the data in terms of skill acquisition and further intervention prospects
are discussed. 相似文献

The existence of spatial components in the mental representation of number magnitude has raised the question regarding the relation between numbers and spatial attention. We present six experiments in which this relation was examined using a temporal order judgment task to index attentional allocation. Results demonstrate that one important consequence of numerical processing is the automatic allocation of spatial attention, which in turn affects the perception of the temporal order of visual events. Given equal onset time, left-side stimuli are perceived to occur before right-side stimuli when a small number (1, 2) is processed, whereas right-side stimuli are perceived to occur before left-side stimuli when a larger number (8, 9) is processed. In addition, we show that this attentional effect is specific to quantity processing and does not generalize to non-numerical ordinal sequences. 相似文献
