Two experiments tested the limiting case of a multiple resources approach to resource allocation in information processing. Results contradict a single-capacity model, supporting the idea that the hemispheres' resource supplies are independent and have implications for both cerebral specialization and divided attention issues.

Perception of pregnancy risk, fertility knowledge, and probability-based teaching examples of risk were assessed in 104 primiparous urban adolescents 13-18 years of age in their second and third trimesters of pregnancy. Perception of risk was not associated with age, actual frequency of intercourse, or level of fertility knowledge. (Author/PN)

In four experiments, college students were presented with lists of either Armenian or English letters on a tachistoscope. The data indicate that extensive practice may be a necessary condition for capacity-free processing but may not be a necessary condition for involuntary processing. (Author/RD)

Reports effects of context that are entirely perceptual. Visual discrimination was enhanced when line segments were flashed in a region that was perceived as a figure. Discrimination was substantially degraded when the same region was seen as ground although the physical stimulus remained identical throughout figure-ground reversals. (Author/JN)

Reaction time and accuracy do not always reflect the same perceptual processes; therefore, the convergence of reaction time with accuracy within the context of a specific information processing model should be demonstrated empirically rather than assumed a priori. (Author/PN)

Using dichotic listening methodology, 25 musicians and 25 nonmusicians were compared on four cerebral lateralization tasks: melodies, tonal patterns, rhythm patterns, and verbal stimuli. Musicians demonstrated superior performance on the music tasks. Results are interpreted in terms of superior cognitive strategies of musicians as a function of…

Results show that the drawings attributed to the Aboriginal "artist" produced more positive impressions and were rated more highly on the semantic differential. This research was presented at the Rocky Mountain Psychological Convention, Denver, Colorado, April, 1978. (Author)

The holistic-discriminability model of object-space perception recognizes various classes of stimuli having different task requirements, with few assumptions. The alternative analytic model, contrary to Dykes and Cooper, is inadequate; it involves many assumptions, predicts only a limited set of data and makes some incorrect predictions.…

This study found that color in a film helped fourth- and fifth-grade students of all ability levels learn incidental information, but affected learning of task-relevant information differently depending on ability level. (Author/JEG)

Defines a "communicate"--the objectification of a subject's internal model of the object of reality by means of a certain set of physical signs--and examines its information value with relation to intelligent systems. (CWM)

The visual imagery of four individuals with blindness was compared with that of five sighted individuals using the detection of mirror symmetry. The two participants who lost their sight later in life outperformed the two with congenital blindness, indicating the importance of early visual experience in visual imagery. (CR)

Theoretical and empirical issues relating to haptic exploration and the representation of common objects during haptic classification were investigated in 3 experiments involving a total of 112 college students. Results are discussed in terms of a computational model of human haptic object classification with implications for dextrous robot…

This study examined phonological processing in 30 less-skilled third-grade readers, 30 younger children at the same reading level, and 30 more-skilled age mates. The less-skilled readers had significantly lower accuracy scores than both age mates and younger normal readers on word span, word-pair repetition, tongue twister, and, especially,…

This article defines tactile defensiveness as a sensory processing problem that results in aversive responses to touch. The article outlines causes, presents sample behaviors to assist in recognizing the possible presence of this dysfunction in infants and toddlers, and offers suggestions to assist in coping with and seeking appropriate treatment…

A large body of data is reviewed to support a new theory of motion perception described by S. Grossberg and M. E. Rudd (1989). The Motion Boundary Contour System is used to explain classical and recent data about motion perception that have not been explained by other models. (SLD)
