Reviews the ideas included in and the debate spawned by the author's paper at the 1974 International Intervisitation Program meeting in Britain. The paper questioned systems theory's adequacy as an exclusive explanation of organizations. (IRT)

Describes an experiment in which the rate of habituation of fixation of 12-week-old infants to a homogeneous stimulus series where a cube was presented in different orientations was contrasted with the rates of habituation to various heterogeneous series where a cube was alternated with some other solid.

Argues that pointing emerges as a component of action-for-self: selective orienting to salient (usually moving or changing things). Pointing with vocalization, followed by pointing with naming, indexes the child's shifting focus of attention. Evidence that pointing emerges for the purpose of intentional communication is lacking.

The qualities expected of a music critic are discussed. (CK)

Activities related to producing OP Art are described. (DB)

A new grouping principle, which depends on perceived depth relations and follows a hierarchical embedding scheme, states that elements located within a common region of space will be perceived as grouped together. Common region produces clear powerful grouping effects, yet cannot be reduced to any other known grouping factor. (RLC)

Functional magnetic resonance imaging (fMRI) was used to investigate the representation of sound categories in human auditory cortex. Experiment 1 investigated the representation of prototypical (good) and nonprototypical (bad) examples of a vowel sound. Listening to prototypical examples of a vowel resulted in less auditory cortical activation…

Despite decades of studies of human infants, a still open question concerns the role of visual experience in the development of the ability to perceive complete shapes over partial occlusion. Previous studies show that newborns fail to manifest this ability, either because they lack the visual experience required for perceptual completion or…

In this paper, we assessed the developmental changes in face recognition by three infant chimpanzees aged 1-18 weeks, using preferential-looking procedures that measured the infants' eye- and head-tracking of moving stimuli. In Experiment 1, we prepared photographs of the mother of each infant and an ''average'' chimpanzee face using…

The authors investigated spatial, temporal, and attentional manipulations in a short-term repetition priming paradigm. Brief primes produced a strong preference to choose the primed alternative, whereas long primes had the opposite effect. However, a 2nd brief presentation of a long prime produced a preference for the primed word despite the long…

The findings of previous investigations into word perception in the upper and the lower visual field (VF) are variable and may have incurred non-perceptual biases caused by the asymmetric distribution of information within a word, an advantage for saccadic eye-movements to targets in the upper VF and the possibility that stimuli were not projected…
