By testing students for depth perception, instructors can identify those students whose monocular vision prevents them from properly drawing three-dimensional objects. (SK)

Program evaluation must be practiced by all members of all trades, disciplines, professions, or any other group of people whose efforts are aimed at making a difference. There is a role for "content free" evaluation methodology resources, but not for a professional "content free" evaluator. (RL)

A multiple habituation paradigm was used to determine whether 10- to 12-month-old infants were able to discriminate between visual arrays differing only in their numerosity. (Author/RH)

Presents and analyzes three experiments on prefix stripping. Results show that pseudoprefixed words are indiscriminately treated as prefixed words and concludes that prefix stripping does occur in word recognition and that prefixed words are accessed through a representation of their stem. (Author/BK)

Infants in more alert states demonstrated significantly higher rates of sucking following sound change. Treating state as a dependent variable revealed that state was not significantly affected by a change in stimulus conditions. (RH)

Four experiments were conducted to investigate the development of visual accommodation in one- to three-month-old infants. Accommodation responses and pupil diameters were measured at various stimulus distances. Results suggest that changes in depth of focus in the first three months are largely responsible for growth in accommodation. (Author/SS)

One- to four-month-old infants' abilities to see various structural characteristics of a subjective contour figure were assessed by means of a habituation procedure. (Author/DB)

Nonsmokers expressed a significant degree of belief in the aversiveness of environmental smoke items. Smokers expressed more skepticism. Both groups expressed strong levels of belief in a general statement on health hazards but less strong belief in statements on specific hazards. (Author/BEF)

The author reviews Plato's epistemological speculations on the nature of perception, memory, and ideation and suggests that, although this dialog is primarily concerned with the nature of knowledge, it can also be construed as reflecting a Platonic conception of cognitive disabilities. (Author)

The capacity of newborn infants for smooth-pursuit eye movements in single-target tracking and in optokinetic nystagmus to a moving striped field was examined utilizing DC electrooculography. (JMB)

Attempts to differentiate the serial habituation hypothesis from the regression to the mean hypothesis as explanations for the reduction of visual fixations in the form perception of four-month-old infants. Results support a regression to the mean interpretation of the data. (JMB)

The thesis of this article is that, in the drawings of very young children, line is produced as a path before it is produced as a boundary. An explanation for this progression is proposed. (Author/JMB)

Explains that motivated behavior is driven by individuals' perceptions and interpretations of external events rather than the events themselves. Suggests a human performance intervention strategy based on a model of motivation that focuses on situation-specific perceptions of value, challenge, and control. (LRW)

In three studies of infants' ability to perceive partially occluded objects with specific appearances, a screen alternately uncovered and covered either a connected or interrupted rectangle. Pattern of infants' looking times suggests that they perceive the unity of the partially occluded object by 6.5 months but did not perceive the form of the…
