Tactile Enumeration and Embodied Numerosity Among the Deaf

Representations of the fingers are embodied in our cognition and influence performance in enumeration tasks. Among deaf signers, the fingers also serve as a tool for communication in sign language. Previous studies in normal hearing (NH) participants showed effects of embodiment (i.e., embodied numerosity) on tactile enumeration using the fingers of one hand. In this research, we examined the influence of extensive visuo-manual use on tactile enumeration among the deaf. We carried out four enumeration task experiments, using 1–5 stimuli, on a profoundly deaf group (n = 16) and a matching NH group (n = 15): (a) tactile enumeration using one hand, (b) tactile enumeration using two hands, (c) visual enumeration of finger signs, and (d) visual enumeration of dots. In the tactile tasks, we found salient embodied effects in the deaf group compared to the NH group. In the visual enumeration of finger signs task, we controlled the meanings of the stimuli presentation type (e.g., finger-counting habit, fingerspelled letters, both or neither). Interestingly, when comparing fingerspelled letters to neutrals (i.e., not letters or numerical finger-counting signs), an inhibition pattern was observed among the deaf. The findings uncover the influence of rich visuo-manual experiences and language on embodied representations. In addition, we propose that these influences can partially account for the lag in mathematical competencies in the deaf compared to NH peers. Lastly, we further discuss how our findings support a contemporary model for mental numerical representations and finger-counting habits.

Interpretation And Understanding

To understand a term or other symbol, I argue that it is generally neither necessary nor sufficient to assign it a unique determinate reference. Independent of and prior to investigation, it is frequently indeterminate not only whether a sentence is true, but also what its truth conditions are. Nelson Goodman's discussions of likeness of meaning are deployed to explain how this can be so.     

Revisiting Sartre on the question of religion

Jean-Paul Sartre's position on religion has traditionally been reduced to variations of his well-known atheism. This is a result of collapsing the distinction between religion and theism, as both critics and supporters of Sartre have commonly done. Consequently, attention to Sartre's persistent and pervasive concern with religious ideas, symbols, and experiences has been neglected. While the religious implications of Sartre's thought have mostly been considered in relation to Christian theology, other newer areas of religious studies suggest additional avenues for considering Sartre. Sartre's possible connections to four such areas are discussed: 1) Eastern religions; 2) Jewish studies; 3) feminist theology, and 4) the psychoanalysis of religion.     

心理差异量对儿童青少年分类活动影响的研究

本研究选择自制的、被试从前未看过的墨渍图为实验材料,探讨心理差异量对分类活动的影响。以４０名１１－２０岁儿童青少年为被试,一方面使用速示仪测量墨渍图之间的心理差异量,一方面要求被试对墨渍图进行自由分类,并说明理由。结果发现：①心理差异量直接影响分类结果。②心理差异量在１１岁、１４岁与１７岁、２０岁之间存在着非常显著的差异（Ｐ〈０．０１）。③分类标准的选择的年龄差异主要表现在分类标准的复杂性方面。     

Enrichment versus exercise effects on motor impairments following cortical removals in rats

Groups of rats were exposed to an enriched environment, given access to an activity wheel, or individually housed in wire mesh cages, impoverished. Rats were exposed in groups of four to the enriched environment or placed individually in the activity wheel for 2 h per day for 25 days preoperatively. Within each exposure group, rats sustained bilateral removals of sensorimotor cortex, or were sham-operated controls. Animals were trained preoperatively to locomote across a narrow elevated runway. Postoperatively, locomotor testing was initiated 17 days after surgery throughout which time all animals were maintained under impoverished conditions. Locomotor deficits following cortical damage were a function of preoperative exposure: enriched rats were least impaired; impoverished rats were most impaired. Rats allowed running wheel activity initially showed the same marked deficits as impoverished animals but recovered more rapidly. The opportunity for physical exercise afforded wheel animals preoperatively may have enhanced motor capabilities that aided recovery. However, physical activity alone did not yield the same protective effects from initial impairment as enrichment. Greater elaboration of neural structures associated with perceptual-motor enrichment probably accounted for the initial sparing of the enriched group.
