Constructing and representing visual objects

The objects we see are not given in the images at the eyes, but must be constructed by the human visual system. Indeed, damage to specific brain regions often leads to specific impairments of visual abilities (for example, the perception of shape, color or motion). Human vision constructs the various properties of visual objects, not independently of each other, but in a highly coordinated fashion. The construction of one visual property strongly influences the constructions of other properties. Visual shape is an important construction for successfully recognizing objects. There is growing consensus that human vision represents shapes in terms of component parts and their spatial relationships. These parts and their spatial relationships provide a powerful first index into one's visual memory of shapes.

This article focuses on the persistent problems of prejudice in multicultural societies. Various theories of prejudice and other psychological, social, and political factors that contribute to prejudice are discussed. The salient feature of this article is the demonstration of several counseling theories and techniques as applied to case vignettes dealing with prejudice and racism.     

Family involvement and empowerment in mental health service provision for children with emotional and behavioral disorders

Involvement of families is a critical component in effective systems of care for children with disabilities and their families. We investigated the sociodemographic correlates of family involvement in mental health services for children who have emotional and behavioral disorders. Further, we investigated the relationship between family involvement and family empowerment. The Family Involvement Scale-Family Version was used to measure involvement of families in the provision of mental services for their children and the Family Empowerment Scale was used to measure pempowerment in families with children who have emotional and behavioral disorders. In additions, demographic data concerming family composition, race, education, incone, membership in a parent support group, and the mental health status of the children were also collected. The results showed that mothers, as well as respondents with less formal education, reported greater involvement in services for their children than fathers and those who were more educated. Further, the knowledge subscale of empowerment was significantly correlated with all, subscales of family involvement and personal empowerment was significantly correlated with the treatment subscale of family involvement.     

The possibility of having knowledge of al‐wujūd al‐mahd ’sheer being’ according to ibn carabi's Kitab al‐jalal wa‐al‐jamal

Mysticism in general makes a distinction between ‘God‐for‐us’ and ‘God‐in‐him‐self. This paper attests that the Muslim mystic‐philosopher, Ibn ‘Arabi's concepts of ‘Sheer Possibility’ and ‘Sheer Being'; ‘Beauty’ and ‘Absolute Majesty’ parallel God‐for‐us and God‐in‐himself. The paper also attempts to examine the extent of possible human knowledge of God beyond the level ‘God‐for‐us'/'Beauty'/'sheer possibility’ and the relation of such developmental knowledge to the Qur'an, according to Ibn ^cArabi. The paper ends with a statement on the need to examine the hermeneutical mechanism supporting this sort of linking of human knowledge with the Qur'an and a need to discuss the possible motives behind traditionalization of developmental knowledge inputs.     

Completing visual contours: The relationship between relatability and minimizing inflections

Visual completion is a ubiquitous phenomenon: Human vision often constructs contours and surfaces in regions that have no sharp gradients in any image property. When does human vision interpolate a contour between a given pair of luminance-defined edges? Two different answers have been proposed: relatability and minimizing inflections. We state and prove a proposition that links these two proposals by showing that, under appropriate conditions, relatability is mathematically equivalent to the existence of a smooth curve with no inflection points that interpolates between the two edges. The proposition thus provides a set of necessary and sufficient conditions for two edges to be relatable. On the basis of these conditions, we suggest a way to extend the definition of relatability (1) to include the role of genericity, and (2) to extend the current all-or-none character of relatability to a graded measure that can track the gradedness in psychophysical data.     

Attitude of the two religious groups towards family planning

40 Muslim and 50 Hindu male high school teachers, working in the interior parts of the districts of Gaya and Shahabad in India, filled out questionnaires designed to determine attitudes toward family planning. All were married and had more than 1 child. They were ages 26-48. The Hindus were found to have significantly more favorable (p less than .05) attitudes toward family planning than the Muslims. If the statistics reflect reality, it is no wonder the birth rate among Muslims is much higher in India. Both Muslim and Hindu teachers were grouped according to age (below 35 years or above 35 years). While the younger Hindus had significantly more favorable (p less than .05) attitudes toward family planning than the older Hindus, the younger Muslims had only slightly more favorable attitudes (nonsignificant) toward family planning than the older Muslims.     

Independence training,need achievement and need affiliation

American white and American Indian grade school boys and girls from the North Central Plains are studied. The previously shown significant and positive relationship between high need achievement and low need affiliation is hypothesized to be a culturally based and sex related phenomenon. The early training of Plains Indian children especially that of boys emphasizes early independence rather than either affiliation or achievement. As hypothesized, it was found in this study both that white children had significantly higher need affiliation scores than Indian children and that boys indicated higher need achievement than girls, indicating cultural and sexual differences. It appeared also that success is a more potent condition for Indian boys in intensifying need achievement scores, whereas failure intensifies the need achievement scores of white children. This suggests that perceived success and failure operate differentially between these cultural groups. Other results also corroborate earlier findings of the culture bias of « standard » intelligence tests.     

The changing intercaste attitudes in North India: A follow-up after four years

Since independence, the government of India, through various constitutional and legislative measures, has tried to root out the evils of the caste system. In order to study the effect of these measures and of various socioeconomic changes on intercaste attitudes, a study of intercaste attitudes conducted by the author in 1968 is used as a baseline to study the changes over the four-year period. The responses to the 15 items compared deal with general caste attitudes, attitudes toward special privileges for the scheduled castes and, the caste Hindus' attitudes toward Harijans (former ‘untouchables’). The comparison of the responses to these items in 1968 and 1972 (the follow-up study) indicates that a higher percentage of respondents gave liberal responses in 1972 than in 1968 to the questions dealing with public and peripheral areas of interaction. However, very little change was found in those spheres of interaction which are relatively personal and central or involve intimate interaction, e.g., the theory of Karma, attitude toward the caste system as such and attitudes toward dining with or acceptance of food from Harijans. The results lend further support to the ‘cognitive imbalance’ theory of attitude change.     

EFFECTS OF SPACED RESPONDING DRL ON THE STEREOTYPED BEHAVIOR OF PROFOUNDLY RETARDED PERSONS

Stereotypic responding and social behaviors of three profoundly retarded children were measured before and during application of a DRL contingency for stereotypic responding. A variant of the standard DRL procedure, spaced responding DRL, was used, in which reinforcement is delivered following a response if that response has been separated from the previous response by at least a fixed minimum time interval. Three children were treated by using a reversal design. Results showed that: (a) during baseline sessions, the children engaged in high rates of stereotypic responding and very low rates of appropriate social behavior; and (b) during DRL sessions, appropriate behavior increased markedly as stereotypic responding was reduced. The data suggest that spaced responding DRL may be effective in increasing appropriate social behavior as well as in reducing stereotypic responding.     

Percentage body weight and the successive negative contrast effect in rats

In two runway experiments employing rats the successive negative contrast effect was evaluated for animals maintained at high or low body weights. In both experiments the effects on performance of shifting reward magnitude were independent of body weight. These results contrast with those of previous studies in which the successive negative contrast effect occurred only under low body weight. It was suggested that when conditions are maximal or near maximal for production of the successive negative contrast effect, as they were here but not in previous investigations, body weight will not influence the size of this effect.
