The aim of this study is to verify the conditions under which a series of visual stimuli (line segments) will be subjectively perceived as visual lines or surfaces employing four experiments. Two experiments were conducted with the method of subjective evaluation of the line segments, and the other two with the Osgood semantic differential. We analysed five variables (thickness, type, orientation, and colour) potentially responsible for the lines’ categorisation. The four experiments gave similar results: higher importance of the variables thickness and type; general lower significance of the variable colour; and general insignificance of the variable orientation. Interestingly, for the variable type, straight lines are evaluated as surfaces more frequently than curved lines and perceived as geometrical, flat, hard, static, rough, sharp, bound, sour, frigid, masculine, cold and passive. Curved lines are prevalently evaluated as lines, and categorised as organic, rounded, soft, dynamic, fluffy, blunt, free, sweet, sensual, feminine, warm and active. These results highlight the specificity of perceptual characteristics for the considered variables and confirm the relevance of the characteristics of variables such as thickness and type.

Differential Test

The nonverbal projective differential test item is described and distinguished from semantic differential items. Projective differential items are pairs of abstract visual stimuli, such as inkblots. Subjects choose one of the two projective stimuli as more similar to a concept being rated. Two studies showed that groups of subjects respond in a consistent manner to such items, with most subjects agreeing that one of the two abstract visual stimuli is more like the concept than the other; this is the projective differential response phenomenon. It was argued that subjects are able to express some aspects of the connotative meanings that concepts have for them through their responses to projective differential items. The potential usefulness of nonverbal items in constructing measuring instruments was discussed.

This study examined the effect of changes in visual elements on spatial comfort and work productivity in the aspect of indoor soundscape perception in the open-plan office (OPO) sound environment. Various OPO visual stimuli were simulated using computer software (Unity 3D engine) to change the visual environment by varying variables such as worker density, window ratio, green ratio, and ceiling height. An interactive virtual reality environment was implemented to perform a specific task while experiencing the audio-visual stimuli combining the general OPO noise stimulus and the simulated OPO visual stimulus. Subjective evaluation was performed on a total of 30 subjects to evaluate indoor soundscape quality and work performance for each stimulus. Based on the results of this study, a pleasant OPO design guideline was proposed. Keywords: Open-plan office, indoor soundscape, interactive VR test, spatial comfort

Similarities And Differences

The interface between tourism and built heritage is complicated because much built heritage is located in the middle of living communities. Questions arise about how to achieve a balance between the expectations of tourists and the community. To study this question, this paper reports on tourists’ and residents’ impressions of an international heritage tourism site, the Kampong Taman Sari in Indonesia. Using a linear-numeric semantic differential as the measuring instrument and nine consensus photographs of the site as stimuli, the study investigated similarities and differences in impressions between three groups: tourists (international and domestic) and residents. Three principal dimensions were found to underlie impressions of the site: Attractiveness, Organisation, and Novelty. Significant differences were found among all three groups in their impressions of Attractiveness. In terms of impressions of the Organisation of the site, international and domestic tourists have similar impressions but these differ significantly from the impressions of residents. On the other hand, domestic tourists and residents have similar impressions of the Novelty of the site, which is evaluated differently by international tourists.

Objective And Subjective Evaluation

In China, noise pollution from substations in urban areas is becoming more and more serious. An annoyance evaluation of the noise emitted by urban substations is presented. First, the subjective evaluation is conducted on the noise samples from urban substations via the semantic differential method. Subsequently, according to the typical characteristics of urban substation noise, 14 acoustical metrics are used to describe the noise samples for objective evaluation. Then the correlation analysis and regression analysis between the objective and subjective evaluation results are carried out. Finally, a regression model for urban substation noise evaluation is established. Practical application shows that the regression model can correctly predict the subjective annoyance of urban substation noise.

There is a need to develop and validate simple, inexpensive techniques for the evaluation of traffic sign messages. This paper examines the semantic differential (a paper-and-pencil test which measures psychological meaning) as a potential instrument for such evaluation. Two experiments are described, one relating semantic differential scores to comprehension and the other relating this index to glance legibility. The data indicate that semantic differential scores on all four factors (evaluative, activity, potency, and understandability) were highly correlated with comprehension of symbolic messages. These scores were unrelated to glance legibility of verbal messages, but two factors (evaluative and understandability) did correlate with glance legibility of symbolic messages. It was concluded that the semantic differential is a valid instrument for evaluating comprehension of symbolic sign messages and that it has advantages over other techniques.

The semantic differential, a means of measuring attitudes, was administered to 178 fourth grade students to compare attitudes toward health. One school was composed almost entirely of black children from the inner city, the other contained white children from upper middle class homes. When the children were divided into the two groups by sex, differences between the groups were not statistically significant but there were highly significant differences between the races. Generally, white children held more positive attitudes toward health personnel and health institutions than black children, while on the average black children were less concerned about sickness than white children. Whether these differences in attitude are in some way ethnically determined or based rather on a "culture of poverty" could not be determined from this study.

Per Se

Audiovisual semantic congruency during memory encoding has been shown to facilitate later recognition memory performance. However, it is still unclear whether this improvement is due to multisensory semantic congruency or just semantic congruencyper se. We investigated whether dual visual encoding facilitates recognition memory in the same way as audiovisual encoding. The participants memorized auditory or visual stimuli paired with a semantically congruent, incongruent or non-semantic stimulus in the same modality or in the other modality during encoding. Subsequent recognition memory performance was better when the stimulus was initially paired with a semantically congruent stimulus than when it was paired with a non-semantic stimulus. This congruency effect was observed with both audiovisual and dual visual stimuli. The present results indicate that not only multisensory but also unisensory semantically congruent stimuli can improve memory performance. Thus, the semantic congruency effect is not solely a multisensory phenomenon, as has been suggested previously.

In this paper we study a class of symmetric polynomial differential systems in R³, which has a set of parallel invariant straight lines, forming degenerate heteroclinic cycles, which have their two singular endpoints at infinity. The global study near infinity is performed using the Poincaré compactification. We prove that for all n <FONT FACE=Symbol>Î</FONT> N there is epsilonn > 0 such that for 0 < epsilon < epsilonn the system has at least n large amplitude periodic orbits bifurcating from the heteroclinic loop formed by the two invariant straight lines closest to the x-axis, one contained in the half-space y > 0 and the other in y < 0.

The increasing number of dysfunctional families causes an increase in the number of civil litigation on the education of the child, where the relationship between the persons are highly conflictual. The actual task is study the one of components in the structure of the psychological relationship - emotional and semantic constructs underlying semantic perception of each other and the child's parents. Examination of 42 testees (parents) from harmonious families and 54 testees (parents) during the forensic psychological and psychiatric examination (regarding the definition of child`s residence or the order of meetings for the child and the parent who don`t live with it) by methods "Geometric test of relations" and "Semantic Differential" showed that in families where is highly conflictual relationship, there is positive assessments of herself and her child, while assessment of the spouse (wife) characterized inversion. This negative attitude toward the spouse (wife) is not the other parent's negative characteristics. It is the ignoring the other parent's positive characteristics. The positive acceptance of all family members was revealed in harmonious families.

Stimulus Complexity

Ss take more time to perceive interesting/displeasing stimuli than uninteresting/pleasing ones. This is consistent with the results of former experiments. However we used a different operationalization of looking time, based on binocular rivalry. Each of six stimulus pairs was presented in a stereoscope. One member of each pair was interesting but displeasing in comparison to the other member. Stimulus complexity was under control. Due to binocular rivalry Ss perceived only one pattern a time. 20 Ss were asked to indicate which pattern they actually saw by pushing two buttons. For each stimulus pair was registered how long each button was pushed during each of six successive minutes. Unlike other operationalizations this one is less dependent on S's determination of what stimulus will be looked at or for how long. It has the advantage that it is bound up more exclusively with relations of similarity and dissimilarity between stimulus elements. It allows manipulation of exposure time in a systematic and continuous way. There is no significant interaction between looking and exposure time.
