It is argued that a reflectance channel that requires priority information is shown to be less plausible for the human visual system than J. L. Dannemiller (1989) argued. In the response, Dannemiller replies that lightness is not an illuminant invariant surface descriptor when daylight illuminant substitutions are considered. (SLD)

The fuzzy logic model of perception (FLMP) is analyzed from a measurement-theoretic perspective. The choice rule of FLMP is shown to be equivalent to a version of the Rasch model. In fact, FLMP can be reparameterized as a simple two-category logit model. (SLD)

Four experiments involving 145 college students (81 males and 64 females) studied the basis of early-stage preattentive perceptual organization. Results suggest that perceptual organization is initially based on a principle in which connected regions of uniform stimulation are inferred to be discrete units (the principle of uniform connectedness).…

Used data from membership survey of National Council on Family Relations to explore variations in demographic profile and organizational attitudes of three professional role identity groups (educators, researchers, practitioners). Found wide variation in the profile and attitudes of the three groups. Concluded that professional role diversity…

Data from 359 married, full-time employed women tested extent to which allocation of tasks and allocation of household management predict perceptions of fairness and conflict. Task and management allocation contributed independently and differently to perceptions of fairness and conflict about housework allocation. Unfairness was predicted by both…

Explores how a dyadic understanding of perception cancels the validity it might have as a model for the linguistic process. Discusses commonly misunderstood exhibits in the gallery of perception studies--the duck-rabbit and Magritte's pipe. (RS)

Perception training can be an integral part of management development programs. These games can help trainees understand what perception is, how it works, and how it applies in the workplace. (JOW)

Attempted to replicate and extend research on work of Kelly and Duran in assessing relationship of group member perceptions of group interaction to group effectiveness. Concludes perceived similarity may not always align with perceptions of cohesiveness. (Author/ABL)

Findings demonstrate a finer partitioning of auditory space near midline than in hemifields. Discusses implications for an understanding of the development of auditory processing mechanisms in sound localizations. (RH)

A think-aloud technique, in which 20 orienteers verbalized their exact thoughts during orienteering, was used to examine the phenomenon of cognition during orienteering. Results indicate that orienteering is experienced as a task to be accomplished, a physical movement, and a dynamic process, and that thinking involves attuning perceptions to…

A study explored the differences in price perceptions of two apparel products when promotions were framed as either a price discount or a gift-with-purchase. The majority preferred the discount. Results illustrate the importance of promotional framing in forming consumer price perceptions. (Contains 30 references.) (Author/JOW)

Prison inmates (n=72) were screened for scotopic sensitivity syndrome (SSS), a visual perceptual dysfunction; 11% had low levels of SSS, 18.1% moderate, and 79.8% high, compared with 12-14% of the general population. Remedial colored overlays improved reading considerably for 55.6%, moderately for 33.3%. (SK)

Examined relationship between visual organization, perceptual closure, and compulsive-like behaviors in 3- to 6-year-olds. Found that children's performance on visual organization and perceptual-closure tasks were significantly related to compulsive-like behaviors reported by parents, and these associations were mediated by mental age. Results…

In developing a theoretical framework for the field of ecological acoustics, Gaver (1993b) distinguished between the experience of musical listening (perceiving sounds) and everyday listening (perceiving sources of sounds). Within the everyday listening experience, Gaver (1993a) proposed that the frequency of an object results from, and therefore…

l, speech perception in noiseBackground noise is a significant factor influencing hearing-aid satisfaction and is a major reason for rejection of hearing aids. Attempts have been made by previous researchers to relate the use of hearing aids to speech perception in noise (SPIN), with an expectation of improved speech perception followed by an…
