In a same—different judgement task with successively presented signals, subjects matched dots in different vertical positions and tones of different frequencies intramodally and intermodally. The first and second stimuli of trials in each of the four modality conditions were drawn from a set consisting of two, three or five alternatives. In all intermodal set size conditions, the dimensions of pitch and vertical position were related by the same equivalence rule. While intramodal performance improvement depended only on the total number of practice trials at matching on the relevant dimensions, intermodal performance improvement appeared to be related to the number of trials practice with each heteromodal stimulus pairing in a particular set. After performance had approached asymptotic level neither intramodal nor intermodal matching reaction time depended on set size. Mean “same” reaction time was less than mean “different” reaction time, and this difference was greater for intermodal matching than for intramodal matching. The results indicated that intermodal equivalence exists between discrete stimulus values on heteromodal dimensions rather than between the dimensions themselves.

Purpose: This article describes a study on the scaffolding of learning to read in a primary-level, continuous-progress, inclusion classroom that stressed a critical thinking curriculum and employed a collaborative teaching model. Two emergent reading groups were the focus of study—one group that was taught by a general educator and the other by a special educator. The primary purposes were to discern the teachers’ discourse patterns in order to define whether scaffolding sequences were more directive or more supportive and the degree to which these sequences represented differentiated instruction for children with a language learning disability (LLD). Method: Two students with an LLD and two younger, typically developing peers were videotaped in their emergent reading groups during an 8-week period. The distribution, types, and functions of teacher scaffolding sequences were examined. Results: Both team members primarily used directive scaffolding sequences, suggesting that the assistance provided to children emphasized only direct instruction (skill learning) and not analytical thinking concerning phonemegrapheme relationships (strategy learning). Distribution of scaffolding sequence types directed to the four students indicated that the two children with an LLD were receiving reading instruction that was undifferentiated from the two typically developing, younger children. Clinical Implications: In order for children with an LLD to benefit from inclusion, explicit, systematic, and intensive instruction in phonological awareness and spelling-sound relationships should be implemented within the context of multilevel instruction that balances skill- and strategy-based learning.


In a tank filled with a suspension of indian ink in tap water, a population of Daphnia magna will undergo a complete cycle of vertical migration when an overhead light source is cycli­cally varied in intensity. A ‘dawn rise’ to the surface at low intensity is followed by the descent of the animals to a characteristic maximum depth. The animals rise to the surface again as the light decreases, and finally show a typical midnight sinking. The light intensities at the level of the animals in this experiment are of the same order as those which have been reported in field observations; the time course of the movement also repeats the natural conditions in the field. The process is independent of the duration of the cycle and is related only to the variation in overhead light intensity. At low light intensity the movement of the animal is determined solely by positive photo-kinesis; the dawn rise is a manifestation of this, and is independent of the direction of the light. At high light intensities there is an orientation response which is superimposed upon an alternating positive (photokinetic) phase and a negative phase during which movement is inhibited. The fully oriented animal shows a special type of positive and negative phototaxis, moving towards the light at reduced light intensities and away from it when the light intensity is increased. In this condition it follows a zone of optimum light intensity with some exactness. Experiments show that an animal in this fully oriented condition will respond to the slow changes of intensity characteristic of the diurnal cycle, while being little affected by tran­sient changes of considerable magnitude.

The popularization of mobile devices in the everyday life of Mexico City's broad socio-cultural sectors, particularly the cell phone, calls attention to the fact that young people read and write permanently, from the moment they wake up to the time they go to bed. They receive and answer dozens of messages throughout the day, and they search and publish all kinds of information. Nonetheless, surveys that measure reading practices leave out questions about these experiences, and subjects, when questioned about their reading habits and preferences, don't mention nor recognize them in their answers. These observations led us to ethnography traditional and emergent reading and writing practices and representations that young people studying Communication in a public university have. Its main results are reviewed in this paper.

The five authors vary in the degree to which the recent neuroscience of the REM state leads them towards multiple dimensions and forms of dreaming consciousness (Hobson et al.; Nielsen; Solms) or toward all-explanatory single factor models (Vertes & Eastman, Revonsuo). The view of the REM state as a prolongation of the orientation response to novelty fits best with the former pluralisms but not the latter monisms.[Hobson et al.; Nielsen; Revonsuo; Solms; Vertes & Eastman]
