This study examines basic number processing (subitizing, automaticity, and magnitude representation) as the possible underpinning of mathematical difficulties often evidenced in deaf adults. Hearing and deaf participants completed tasks to assess the automaticity with which magnitude information was activated and retrieved from long-term memory…

Previous research with both brain-damaged and neurologically intact populations has demonstrated that the right cerebral hemisphere (RH) is superior to the left cerebral hemisphere (LH) at detecting anomalies (or incongruities) in objects (Ramachandran, 1995; Smith, Tays, Dixon, & Bulman-Fleming, 2002). The current research assesses whether the RH…

Two experiments explore the activation of semantic information during spoken word recognition. Experiment 1 shows that as the name of an object unfolds (e.g., lock), eye movements are drawn to pictorial representations of both the named object and semantically related objects (e.g., key). Experiment 2 shows that objects semantically related to an…

Braking to avoid a collision can be controlled by keeping the deceleration required to stop (i.e., ideal deceleration) in the "safe" region below maximum deceleration, but maximum deceleration is not optically specified and can vary as conditions change. When brake strength was manipulated between participants using a simulated braking task, the…

Recent studies have reported that preverbal infants are able to discriminate between numerosities of sets presented within a particular modality. There is still debate, however, over whether they are able to perform intermodal numerosity matching, i.e. to relate numerosities of sets presented with different sensory modalities. The present study…

The abilities of 19 adult students with dyslexia and 19 students without dyslexia to recall number facts were compared. Despite being matched for estimated IQ, the dyslexic students were less accurate than the non-dyslexic students when answering subtraction and multiplication questions. When the dyslexic students answered addition and subtraction…

Current theories of environmental cognition typically differentiate between an online, transient, and dynamic system of spatial representation and an offline and enduring system of memory representation. Here the authors present additional evidence for such 2-system theories in the context of the disorientation paradigm introduced by R. F. Wang…

Bilingual reading can require more than knowing two languages. Learners must acquire also the writing conventions of their second language, which can differ in its deep mapping principles (writing system) and its visual configurations (script). We review ERP (event-related potential) and fMRI studies of both Chinese-English bilingualism and…

This paper discusses a mental model of learning based on the processes of attention, perception, processing, and application. The learning process starts with attention, such as curiosity, excitement, expectation, or fear; in pedagogy this is called motivation. New impressions are dependent on and interpreted against the background of previous…

To investigate the relationship between the location of the words being read and the location of the eyes in the text, three experiments were conducted using the Disappearing Text Technique with college students. This was done by occasionally removing the text during reading and having the reader report the last word that had been read.…

The defining attributes of analytic ability as they relate to theoretical cognitive styles were explored in a study using a sample of 492 males aged 16-21 years. The Group Embedded Figures Test (GEFT--Witkin, Oltman, Rasher, and Karp) was used to measure field dependent and independent aptitude. Scores on the GEFT were compared with scores on an…

The difference in cognitive resources required for imagination and perception was tested in two experiments by examining the reduced substitutability of imagination and perception in problem solving by college undergraduates. Eighty subjects in Experiment 1 drew capital letters from lines or descriptions of lines in a seven-page booklet. The…

Experimental phenomenology requires that educators acknowledge the experiences of the learner. Today, many of those experiences are images that come from television. In a behaviorist or humanist tradition, learning takes place through experience, and learners comprehend, make decisions, and analyze their behavior through reflection. Meaning is…

Two experiments investigated the linear and nonlinear processes involved in a visual search of letter displays. The displays used in the experiments were well-illuminated 6 x 6 degree or 10 x 10 degree fields containing from 2 to 23 capital As, Bs, or Cs located randomly over the displays. The task of the subjects was to decide as rapidly as…

One hundred twenty-three fifth grade students participated in a study that investigated the role of prosodic cues in children's comprehension of discourse. The subjects, both good and poor readers, read, listened to, or read and listened to a story in one of four modes of visual and auditory presentation: (1) no audio, (2) normally intoned, (3)…
