Thirty college students attempted to form three 3-node 5-member equivalence classes under the simultaneous protocol. After concurrent training of AB, BC, CD, and DE relations, all probes used to assess the emergence of symmetrical, transitive, and equivalence relations were presented for two test blocks. When the A-E stimuli were all abstract…

Advocates of modality preference posit that individuals have a dominant sense and that when new material is presented in this preferred modality, learning is enhanced. Despite the widespread belief in this position, there is little supporting evidence. In the present study, the authors implemented a Morse code-like recall task to examine whether…

Five experiments were performed to identify the basic Spanish colour categories (BCCs) and to locate them in the CIE L*u*v* space. The existence of 11 BCCs was confirmed using an elicited list task and a free monolexemic naming task. From the results provided by a synonymicity estimation task, it was concluded that, in Spanish, 2 synonymous terms…

Data suggest that human newborns are capable of making a chromatic discrimination within the spectral region above 540 nm (the Rayleigh region), but their ability is limited to chromatic stimuli of very wide spectral separation and of very large size. Possible neurological bases underlying this immaturity are discussed. (RH)

Twenty-seven 4-month-old infants heard a repetitive auditory rhythm, then viewed silent film of puppet opening/closing its mouth, either in the familiar rhythm or a novel rhythm. Results showed infants exposed to the novel condition watched the film longer than infants shown the familiar condition, providing evidence for auditory-visual transfer…

Confirms the existence of a right-hemisphere advantage in the process of discriminating between face stimuli. The advantage was weaker in females than in males. No hemispheric transfer of learning was observed. Subjects were 18 infants of 42 weeks who were presented with an operant conditioning situation in which they discriminated between their…

Six same-different matching tests, both verbal and nonverbal in three modalities along with a set of reading tests, were administered to 120 Israeli children in second, third and fourth grade. (MS)
