The effect on the capacity of visual working memory of spatial complexity (as defined by Garner's principle) in rotation and reflection transformation was examined in persons differing along the Autism Spectrum Quotient (AQ), using a change-detection task. On each trial, nine line segments were arrayed in simple, medium, and complex configurations, which were presented in memory and test displays. 27 participants (8 men, 19 women; M age = 22.3 yr., SD = 2.7) were asked whether the orientations of stimuli between two displays were the same or different. On the basis of their AQ scores out of 50 (M AQ scores = 20.9, SD = 6.3), the participants were divided into groups with high (n = 13; M AQ scores = 26.2, SD = 4.1) and low (n = 12; M AQ scores = 15.3, SD = 2.7) self-reported autistic-like traits (High and Low AQ groups, 2 excluded for scores at the median). The results showed that spatial complexity affects the capacity of visual working memory for the Low AQ group but not for the High AQ group, suggesting the functional dissociation of spatial configuration and visual working memory in the High AQ group. 相似文献

Exposure to a microgravity environment leads to adverse effects in motion and musculoskeletal properties. However, few studies have investigated the recovery of altered locomotion and muscle atrophy simultaneously. The authors investigated altered locomotion in rats submitted to simulated microgravity by hindlimb unloading for 2 weeks. Motion deficits were characterized by hyperextension of the knees and ankle joints and forward-shifted limb motion. Furthermore, these locomotor deficits did not revert to their original form after a 2-week recovery period, although muscle atrophy in the hindlimbs had recovered, implying discordance in recovery between altered locomotion and muscle atrophy, and that other factors such as neural drives might control behavioral adaptations to microgravity. 相似文献

A survey of 1,150 fathers and 1,147 mothers in four regions of Japan (mean ages: FATHERS = 36.7, MOTHERS = 33.8, CHILDREN = 4.4 years) documented Japanese parents' sources of advice and information about young children. Mothers reported receiving more advice and information from more sources, compared with fathers. However, more husbands and wives cited “my spouse” than any other potential source of advice, and men and women expressed a high level of confidence in each other. Relatively few parents said that they had used professional advice. It is apparent that various sources of parenting knowledge can be facilitated to alleviate the stress felt by today's increasingly isolated parents. 相似文献

Pattern redundancy is a key concept for representing the amount of internal mental load (encoding efficiency) needed for pattern perception/recognition. The present study investigated how pattern redundancy influences encoding and memory processes in the visual system using a rapid serial visual presentation (RSVP) paradigm. With RSVP, it is well known that participants often fail to detect repetitions of words (repetition blindness, RB). We used this phenomenon as an index of the encoding and storage of visual patterns. In three experiments, we presented patterns with higher and lower redundancy, as defined by Garner’s equivalent set size (ESS). The results showed that RB occurred more frequently for higher redundancy patterns when the temporal distance between the targets was less than 500 ms; this tendency was reversed with longer temporal distances of over 500 ms. Our results suggest that pattern redundancy modulates both the early encoding and subsequent memory processes of a representation. 相似文献

It has been indicated that visual search is interfered with in spatial working memory (WM), although not in nonspatial WM. In this study, the effects on visual search of individual differences in spatial and nonspatial WM were examined. Two visual search conditions were used: a conjunction search condition comprising two features (color and shape) and a disjunction condition comprising only one feature (color or shape). 96 participants (42 men, 54 women, M age = 20.9 yr., SD = 3.5) participated in this study. The participants were divided into high and low WM groups based on their spatial and nonspatial WM test scores. As a result, statistically significant group differences in the conjunction search rate were observed in spatial WM but not in nonspatial WM. These results suggest there is a relationship between visual search and the individual spatial WM ability, but this does not hold for nonspatial WM. 相似文献

The interactions between dislocations and lath boundaries in Grade 91 steel were observed by an in situ transmission electron microscopy tensile test at 973 K. Dislocations glided slowly and bowed out in a martensite lath interior. The ends of the dislocation were connected to the lath boundaries. In a tempered specimen, the pinning stress caused by the lath boundary was estimated to be >70 MPa with a lath width of 0.4 μm. In crept specimens, lath coarsening reduced the pinning effect. 相似文献
