“Center-of-gravity” Tendencies for fixations and flow patterns

Fixation positions were measured for a variety of simple patterns. Generally, the spontaneous fixation tendencies hovered near the “center-of-gravity” of the pattern, providing that the overall dimensions of the figure were less than about 5 deg. “Open” figures such as angles were found to be roughly equivalent to their “enclosed” counterparts, such as triangles. The constraints imposed by the pattern upon the fixation tendencies occur at a level where the binocular inputs are processed. Of further importance was the fact that the fixation points approximate the foci observed in the same patterns when they are seen against a background of visual noise. It is suggested that the two results may be functionally related..     

Stereopsis with opposite contrast contours

The effects of incidental stimuli, defined as visual stimuli not under verbal control, upon a selection task were observed as a function of feedback contingency. Ss judged letter pairs to be valid or invalid completions of preceding letter parts. During the presentation of the letter parts, the response pair or an alternative pair of letters was intermittently presented at a threshold value individually determined for each S. One group of Ss received a light feedback of performance contingent upon responding to the incidental stimuli; whereas a second group received a random noncontingent feedback. The results indicated: (a) both groups responded to the incidental stimuli; (b) feedback contingency had no effect on frequency of responding to the incidental stimuli; (c) frequency of responding to the incidental stimuli remained constant over 32 trials.     

Continuity effects with alternately sounding tones under dichotic presentation

An experiment is reported in which 10 Ss possessing normal hearing were required to make discriminations of continuity or interruption in a longer less intense signal (Tone A) which alternated in time with a shorter more intense signal (Tone B). The signals were presented dichotically with Tone A at the right ear. Three Tone B frequencies of 300, 1000, and 4000 cps and five Tone A frequencies somewhat near each of the Tone B frequencies were employed. The results demonstrated that as Tone A was nearer to Tone B in frequency, continuity thresholds in Tone A occurred at longer durations of Tone B. The results are discussed in terms of a central neural model.     

Binocular fusion: A test of the suppression theory

Binocular fusion may be due to interocular inhibitory suppression, an hypothesis difficult to evaluate by phenomenal inspection. A test probe method (reaction time to a light pulse) was used to measure visual sensitivity during binocular rivalry and fusion. The absence of inhibitory effects during fusion fails to support the suppression theory of fusion.     

Prototyping “Intelligent” applications for interactive multimedia systems

The termmultimedia refers to the combined use of different media of communication, and originally belonged primarily to the fields of entertainment and education. Advances in computer, audio, and video technology have now brought multimedia possibilities to the individual. Further, they give the user control over what happens. Suchinteractive multimedia systems offer the user personal access to large amounts of information, including pictures, graphics, video, text, and audio. The potential range of applications is very broad, from simple interactions where the user will merely make occasional choices and then sit back and view sections of program material, to more purposeful interactions where the application can help the user to achieve a goal. This article describes research onknowledge-based interactive multimedia systems. Targeted on the new Compact Disc Interactive format, we have protyped an advisor which will help the user to tackle a typical domestic task. The necessary decision-making process can be enlivened by multimedia interaction, and placed on solid ground by the inclusion of expert advice.     

Ignorance is not a victimless crime: The case of the caring teacher,part 2

Confusion about the mandated reporting of child abuse was discovered in a case study to be widespread, including at the state level. Such extensive confusion serves to keep citizens from both seeing the depth of suffering to which children are subjected and responding appropriately to their suffering; and it serves to keep society dissociated from the impact violence has on us.     

Sexual equality,male superiority,and Korean women in politics: Changing gender relations in a “patriarchal democracy”

As a newly industrialized country Korean society may be characterized as a patriarchal democracy, where the Western democratic principle of sexual equality and the traditional Confucian ideology of male superiority contradict each other and complicate the behavioral rules for gender relations. This paper explores the processes of social change in gender relations by examining organizational patterns of social actions of individuals in male-female interactions in South Korea, with a focus on the experiences of women in politics. The analysis suggests the emerging pattern of gender relations in Korean society is a compartmentalized gender schema that is fluid and situationally defined by the individual's nunch'i (tact or savoir-faire).The research on which this paper is based was funded by grants from the National Science Foundation and the East-West Center. I am grateful to the two institutions. Special thanks are also due to Jerry Boucher, Jon McGee, and an anonymous reviewer for their helpful comments on early versions of this paper.
