For clinical assessment as well as student training, there is a need for information pertaining to the perceptual dimensions of dysphonic voice. To this end, 24 naive listeners judged the similarity of 10 female and 10 male vowel samples, selected from within a narrow range of fundamental frequencies. Most of the perceptual variance for both sets of voices was associated with "degree of abnormality" as reflected by perceptual ratings as well as combined acoustic measures, based upon filtered and unfiltered signals. A second perceptual dimension for female voices was associated with high frequency noise as reflected by two acoustic measures: breathiness index (BRI) and a high-frequency power ratio. A second perceptual dimension for male voices was associated with a breathy-overtight continuum as reflected by period deviation (PDdev) and perceptual ratings of breathiness. Results are discussed in terms of perceptual training and the clinical assessment of pathological voices.

The aim of this work has been to detect the differences and similarities from the point of view of Music Education among the Programas Renovados (Renewed Programs), the last document published in Spain before the emergence of the curriculum concept and how we conceive it today, and the Real Decree 1006/1991, that established the curricula for Primary School. For this, a comparative analysis of the aforementioned texts has been carried out through a documentary analysis that has allowed to contrast the legal framework, the character, the curricular functions, the configuration of the music area, structure, elements, musical areas, as well as the degree of concretion of both documents. The results reveal a high degree of difference between the Renewed Programs and Royal Decree 1006/1991 regarding the curricular functions, because the former served as a guide for the teaching staff, while the latter, in addition to the previous function, made explicit the intentions of the educational system for the stage. Likewise, a high degree of difference between the structure of the Musical Education elements of both documents has been verified. However, it has been observed a common presence of contents related to different areas of Music Education (singing, instrumentation, listening, movement and dance...), as well as a dual approach that includes the perceptual dimension and expressive of them.

The Individual

The classification behaviour of human observers with respect to compound Gabor signals was tested at foveal and extrafoveal retinal positions. Classification performance was analysed in terms of a probabilistic classification model recently proposed by Rentschler, Jüttner, and Caelli (1994 Vision Research34 669 – 687). The analysis allows inferences about structure and dimensionality of the individual internal representations underlying the classification task and their temporal evolution during the learning process. With this technique it was found that the internal representations of direct and eccentric viewing are intrinsically incommensurable in the sense that extrafoveal pattern representations are characterised by a lower perceptual dimension in feature space relative to the corresponding physical input signals, whereas foveal representations are not (Jüttner and Rentschler, 1996 Vision Research in press). We then addressed the question to what extent observers are capable of generalising class concepts that have been acquired at one particular retinal location to other retinal sites. We found partial generalisation with respect to spatial translation across the visual field. Moreover, there is, in the case of extrafoveal learning, a distinct asymmetry in performance with respect to the visual hemifield in which the signals were originally learned. The latter finding can be related to functional hemispheric specialisation in pattern learning and recognition.

Personality Typology

This study examined the distributions across personality types (as assessed by the Myers-Briggs Type Indicator) of two samples of black college students ( ns = 315 and 447) in comparison to norming data from two manuals. Major differences were found between the black and white samples with regard to the proportions classified as Extroversion-Intuition-Feeling-Perception (ENFP) and Introversion-Sensing-Thinking-Judging (ISTJ). Much higher proportions of the black samples were also clustered at the sensing pole of the perceptual dimension. The findings are discussed in terms of their implications for the existence of a unique black “cognitive style.”

Letter Task

Task-switching experiments have documented a puzzling phenomenon: Advance warning of the switch reduces but does not eliminate the switch cost. Theoretical accounts have posited that the residual switch cost arises when one selects the relevant stimulus–response mapping, leaving earlier perceptual processes unaffected. We put this assumption to the test by seeking electrophysiological markers of encoding a perceptual dimension. Participants categorized a colored letter as a vowel or consonant or its color as “warm” or “cold.” Orthogonally to the color manipulation, some colors were eight times more frequent than others, and the letters were in upper- or lowercase. Color frequency modulated the electroencephalogram amplitude at around 150 ms when participants repeated the color-classification task. When participants switched from the letter task to the color task, this effect was significantly delayed. Thus, even when prepared for, a task switch delays or prolongs encoding of the relevant perceptual dimension.

The Relationship

We visually perceive meaning from stimuli in the external world. There are inter-individual variations in the perception of meaning. A candidate factor to explain this variation is positive schizotypy, which is a personality analogous to positive symptoms of schizophrenia (e.g., visual hallucination). The present study investigated the relationship between positive schizotypy, and the perception of meaning derived from meaningful and meaningless visual stimuli. Positive schizotypy in Japanese female undergraduates (n = 35) was assessed by the Cognitive-Perceptual dimension of the Schizotypal Personality Questionnaire. The participants were asked to report what they saw in noise-degraded images of meaningful objects (Experiment 1) and to respond whether the objects were meaningful (Experiment 2A) and which paired objects were meaningful (Experiment 2B). Positive schizotypy (i.e., Cognitive-Perceptual score) did not correlate with time to detect meaningful objects, and with false-alarm rates, sensitivity, and response criterion in the perception of meaning from meaningful and meaningless stimuli. These results were against our hypothesis and contradicted previous findings. The inconsistencies are discussed in terms of different methods (e.g., stimulus category) and conditions (e.g., paranormal beliefs).

Kathmandu valley has been urbanizing rapidly but the planning of neighborhoods is limited to land readjustments and housing developments. The focus of such development is to provide either the service plots or ready to move in housing stock. Residential Environment Satisfaction (RES) has been used as a concept to measure the perceptual dimension neighborhood planning. Moreover, neighborhood safety is a key priority while considering RES. This paper aims to examine the relationships between various factors related to the safety as a measure of the RES in the planned residential neighborhood in Kathmandu Valley. Since the planned cities or communities seem to have better residential satisfaction, the case study area surveyed upon is Purano Sinamangal Town planning, a land pooling area nearly at junction to three major districts of Kathmandu valley. Various factors have been taken as a measure for neighborhood safety including physical and socio-psychological variable. This research is based on a mixed method. A figure of 109 households was determined as sample household size and individual representatives were interviewed for the survey. The research finds that perception of safety is very high depending on the ethnic groups while it is also significant in case of occupation that the respondent holds. The reason for safety highly was found to be dependent upon good street design, the presence of good neighbors and provision of security patrols. Also, annoyance factors such as disturbances from street and vehicles, crimes, neighborly disputes were found to make the neighborhood unsafe. The research concludes that safety is a major concern for RES and it had been perceived by the residents through significant of good neighborly relation and safety measures in road planning and design.

Colours are linked to emotional concepts. Research on the effect of red in particular has been extensive, and evidence shows that positive as well as negative associations can be salient in different contexts. In this paper, we investigate the impact of the contextual factor of polarity. According to the polarity-correspondence principle, negative and positive category poles are assigned to the binary response categories (here positive vs. negative valence) and the perceptual dimension (green vs. red) in a discrimination task. Response facilitation occurs only where the conceptual category (valence) and the perceptual feature (colour) share the same pole (i.e., where both are plus or both are minus). We asked participants (n = 140) to classify the valence of green and red words within two types of blocks: (a) where all words were of the same colour (monochromatic conditions) providing no opposition in the perceptual dimension, and (b) where red and green words were randomly mixed (mixed-colour conditions). Our results show that red facilitates responses to negative words when the colour green is present (mixed-colour conditions) but not when it is absent (monochromatic conditions). This is in line with the polarity-correspondence principle, but colour-specific valence-affect associations contribute to the found effects.
