Discourse describing evolution in contemporary popular science writing often posits that humans evolved not from an ape, but from a merely ape-like or generalized primate. Contemporary fossil and genetic evidence, though, have revealed what can accurately be described as an extinct ape species as ancestral to the human lineage. The persistence of ambiguous terms in popular science writing may be interpreted as a form of anthropocentric rhetorical discourse. Nonetheless, while such discourse is often justified in terms of increasing the public understanding of science, it may also mitigate (whether consciously intended or not) religion-based resistance to evolutionary theory.  相似文献

ObjectiveChildren with Developmental Coordination Disorder demonstrate a lack of automaticity in handwriting as measured by pauses during writing. Deficits in visual perception have been proposed in the literature as underlying mechanisms of handwriting difficulties in children with DCD. The aim of this study was to examine whether correlations exist between measures of visual perception and visual motor integration with measures of the handwriting product and process in children with DCD.MethodThe performance of twenty-eight 8–14 year-old children who met the DSM-5 criteria for DCD was compared with 28 typically developing (TD) age and gender-matched controls. The children completed the Developmental Test of Visual Motor Integration (VMI) and the Test of Visual Perceptual Skills (TVPS). Group comparisons were made, correlations were conducted between the visual perceptual measures and handwriting measures and the sensitivity and specificity examined.ResultsThe DCD group performed below the TD group on the VMI and TVPS. There were no significant correlations between the VMI or TVPS and any of the handwriting measures in the DCD group. In addition, both tests demonstrated low sensitivity.ConclusionClinicians should execute caution in using visual perceptual measures to inform them about handwriting skill in children with DCD.  相似文献

To investigate possible iPad related mode effect, we tested 403 8th graders in Indiana, Maryland, and New Jersey under three mode conditions through random assignment: a desktop computer, an iPad alone, and an iPad with an external keyboard. All students had used an iPad or computer for six months or longer. The 2-hour test included reading, math, and writing items adapted from released NAEP 8th grade tests. Overall, no significant difference was found on the reading, math, or writing section scores or section response time among the three mode conditions. Further, roughly comparable numbers of students reportedly favored testing using an iPad or a desktop computer, but using a preferred mode did not lead to significantly higher section scores. These findings suggest that there is no noticeable disadvantage associated with taking a test on an iPad than on a desktop computer for experienced users of these two studied devices.  相似文献

To examine the mechanism of visual perception of human-like body postures, we conducted a posture recognition task, a questionnaire survey, and the Interpersonal Reactivity Index (IRI). The majority of participants perceived the pseudo-posture as a human posture in the early stage (78%), but only approximately half of them reported the imagination of bodily movement (66%). These results suggest that the majority of observers perceive pseudo-postures as human postures in the early stage of perception, but this human posture perception does not necessarily lead to the visualisation of bodily movement. In a group of who received the pseudo posture as a human-posture regardless of the perception stages, the participants who imagined bodily movement (64%) showed significantly higher scores than those who did not on the Fantasy subscale of the IRI. Highly empathic participants are more likely to detect a kinematic relation between the pseudo-postures.  相似文献

This study evaluates age-related proximal and distal changes in reaching organization for objects of different sizes. To this end, eight objects ranging from 2 to 9 cm diam. were presented to 23 infants ages 5 to 12 months. Proximal control was determined by the relative frequencies of bimanual reaching for large and small objects. Distal control was assessed by hand opening and orientation with respect to an object, and by the proportion of the object being included within hand opening at touch. Five-month-old infants tended to reach bimanually regardless of object size. Starting at 7 to 8 months, infants tended to reach for large objects bimanually more often than for small ones. Only at 11 to 12 months did reaching closely reflect the object’s diameter. The frequency of thumb-index finger angle opening during the approach phase also increased after 7 to 8 months of age, as well as the adjustment of the angle to the object diameter and the proportion of the object within hand opening at touch. Proximal and distal changes appeared coupled at 5 to 6 months, when the few subjects showing evidence of some proximal adjustments to object size were also those who exhibited some distal adjustments. After they started to appear, however, proximal and distal adjustments seemed to be independent, as revealed by the lack of correlation of proximal and distal changes between 7 and 12 months.  相似文献

The author presents a hypothetical view of group therapy theories as they may evolve over the first decades of the New Milennium. Looking at the problem of prediction from the standpoint of postmodernism and social constructivism, the importance of these perspectives as frameworks of the social sciences is emphasized. The influence of general systems theory, Foulkesian group analysis, object relations theory, self psychology, cognitive-behavioral psychology, and neuropsychiatry are briefly examined with respect to the expected evolution of increasingly sophisticated, detailed, and nuanced theories of group psychology and group psychotherapy.  相似文献

This study provides an innovative, compassionate and culturally informed method for psychotherapy research, using object elicitation with 13 participants from vulnerable groups. It examines the positive impact it has on building the research alliance, enhanced depth of sharing within qualitative research interviews and emic ways of knowing through the engagement with a culturally relevant, tangible, internalised or transitional object brought by vulnerable participants from diverse cultural contexts of origin. Results showcase how a creative and compassionate research method can promote a culturally informed research alliance with vulnerable participants, helping to build trust, rapport and relational depth; encourage elicitation of experiences; and empower emic and subjugated voices. The implications of this study make the case for the inclusion of object elicitation as a creative and compassionate method in qualitative research with traumatised and vulnerable individuals, which should be used as part of a culturally informed approach to psychotherapy research.  相似文献

In Thinking without Words I develop a philosophical framework for treating some animals and human infants as genuine thinkers. This paper outlines the aspects of this account that are most relevant to those working in animal ethics. There is a range of different levels of cognitive sophistication in different animal species, in addition to limits to the types of thought available to non-linguistic creatures, and it may be important for animal ethicists to take this into account in exploring issues of moral significance and the obligations that we might or might not have to non-human animals. I am grateful for comments on an earlier version from Robert Francescotti and Clare Palmer.  相似文献
