Effects of combining disparate groups in the analysis of ethnic differences: Variations among asian american mental health service consumers in level of community functioning

The Asian American population comprises historically, socially, and culturally diverse ethnic groups. Given this diversity, investigators caution that combining disparate ethnic groups together may lead to erroneous conclusions. Whether by choice or necessity, however, mental health studies still typically consider Asian Americans as a single ethnic category rather than as separate ethnic groups. Few investigations have addressed the consequences of this practice. This paper examines the implications of conceptualizing Asian Americans as an ethnic category versus ethnic groups, in an investigation of the community functioning status of clients in publicly funded mental health programs in King County, Washington. When treated as a single ethnic category in a multivariate linear regression model, Asian Americans are found to have a lower level of functioning difficulty than their white counterparts. However, when treated as separate ethnic groups (e.g., Vietnamese, Japanese), only one of five Asian ethnic groups has a significantly lower level of difficulty. In a separate analysis of the Asian American subsample, groups are found to differ significantly from one another with respect to functional status. Several factors, including refugee status, account for this difference.     

The importance of the individual in the ‘causal’ relationship between attractiveness and self-esteem

This paper argues that many psychological explanations underlying health and social behaviour stress the importance of the relationship between attractiveness and self-esteem. The nature of this relationship is not well understood, yet can have important implications for the individual in areas of medical intervention which involve treatment on aesthetic grounds. A survey of psychosocial factors among 1018 children aged 11-12 years is reported. The study examined the association between perception of physical attractiveness and self-esteem in order to clarify the relationship between self-esteem and self versus others' perception of attractiveness. Self-ratings of attractiveness were linked to judges' ratings to determine whether subjects underrated, over-rated, or accurately perceived their own physical attractiveness. The results showed that although ratings of general facial attractiveness by others were associated with self-perceived attractiveness, in the specific area of dental health, attractiveness (as judged by others) was not. There were no significant relationships between ratings of attractiveness by others and self-esteem. Self-perception of attractiveness, however, was significantly associated with self-esteem. Further analyses showed that children who under-rated their own facial attractiveness had a lower mean score for self-esteem than over-raters or accurate perceivers (who did not differ significantly). In contrast, under-raters of dental attractiveness had a lower mean score for self-esteem than over-raters, but did not differ significantly from accurate perceivers. Over-raters of dental attractiveness had a higher mean score for self-esteem than accurate perceivers. These finding suggest that if an over-rater were to receive treatment on aesthetic grounds it is unlikely, given that they have high self-esteem already, that such intervention will have a profound psychological impact. These data indicate the importance of determining the way in which individuals evaluate their appearance compared to others, and may help to clarify previously equivocal findings concerning the relationship between self-esteem and attractiveness.     

Observation can be as effective as action in problem solving

This study discusses findings that replicate and extend the original work of Burns and Vollmeyer (2002) , which showed that performance in problem-solving tasks was more accurate when people were engaged in a non-specific goal than in a specific goal. The main innovation here was to examine the goal specificity effect under both observation-based and conventional action-based learning conditions. The findings show that goal specificity affects the accuracy of problem solving in the same way when the learning stage of the task is observation-based as when it is action-based. In addition, the findings show that, when instructions do not promote goal specificity, observation-based problem solving is as effective as action-based problem solving.     

A Neo-Kantian foundation of Corporate Social Responsibility

‘Corporate Social Responsibility (CSR) is conceptualized in many ways. We argue that one cannot be indifferent about the issue of its conceptualization. In terms of methodology, our position is that any conceptual discussion must embed CSR in political theory. With regard to substance, we link up with the discussion on whether CSR must be defined on the basis of a tripartite or a quadripartite division of business responsibilities. We share A.B. Carroll’s intuition that a quadripartite division is called for as a basis to define CSR. However, defending the quadripartite division of business responsibilities requires that the distinctions between economic, legal, ethical and discretionary business responsibilities be made intelligible. Carroll’s account is defective in this respect. We argue that contemporary Neo-Kantian political ethics is able to make sense of these distinctions, because of its specific interpretation of liberalism. Interestingly, from a conventional liberal perspective this interpretation of liberalism is atypical, as it extends public morality beyond the domain of the law.

Local rather than global processing of visual arrays in numerosity discrimination by pigeons (Columba livia)

A series of experiments investigated which stimulus properties pigeons use when they discriminate pairs of visual arrays that differ in numerosity. Transfer tests with novel stimuli confirmed that the birds’ choices were based on relative differences in numerosity. However, pigeons differed from other species in the non-numerical cues that affected their choices. In human and non-human primates, numerical discrimination is often influenced by continuous variables such as surface area or overall stimulus brightness. Pigeons showed little evidence of using those cues, even when summed area and brightness had been correlated with numerosity differences and reward outcome. But when array-element sizes were asymmetrically distributed across numerosities, the birds readily utilized information about item sizes as an additional discriminative cue. These novel results are discussed in relation to pigeons’ tendency to focus on local, rather than global dimensions when they process other non-numerical complex visual stimuli. The findings suggest there may be inter-specific differences in the type of perceptual information that provides the input stage for mechanisms underlying numerical processing.

Stability of choices in a risky decision‐making task: a 3‐year longitudinal study with children and adults

In a 3‐year follow‐up to Levin and Hart's ( 2003 ) study, we observed the same children, now 9–11 years old, and their parents in the same risky decision‐making task. At the aggregate level the same pattern of means was observed across time periods. At the individual level the key variables were significantly correlated across time periods for both children and adults. Taken together with the results from the original study and earlier studies, these results solidify the following conclusions: children utilize both probability and outcome information in risky decision‐making; the tendency to make more risky choices to avoid a loss than to achieve a gain of equal magnitude, which is a major tenet of the leading theories of risky decision‐making, occurs for children as well as adults; children make more risky choices than adults; temperamental predictors of risky choice are valid for children as well as for adults.

CAN WE STILL TALK ABOUT “TRUTH” AND “PROGRESS” IN INTERDISCIPLINARY THINKING TODAY?

On a cultural level, and for Christian theology as part of a long tradition in the evolution of religion, evolutionary epistemology “sets the stage,” as it were, for understanding the deep evolutionary impact of our ancestral history on the evolution of culture, and eventually on the evolution of disciplinary and interdisciplinary reflection. In the process of the evolution of human knowledge, our interpreted experiences and expectations of the world (and of the ultimate questions we humans typically pose to the world) have a central role to play. What evolutionary epistemology also shows us is that we humans can indeed take on cognitive goals and ideals that cannot be explained or justified in terms of survival‐promotion or reproductive advantage only. Therefore, once the capacities for rational knowledge, moral sensibility, aesthetic appreciation of beauty, and the propensity for religious belief have emerged in our biological history, they cannot be explained only in biological/evolutionary terms. Finally, in this way a door is opened for seeing problem solving as a central activity of our research traditions. As philosophers of science have argued, one of the most important shared rational resources between even widely divergent disciplines is problem solving as the most central and defining activity of all research traditions. As will become clear, the very diverse reasoning strategies of theology and the sciences clearly overlap in their shared quests for intelligible problem solving, including problem solving on an empirical, experiential, and conceptual level.     

Playing on the typewriter, typing on the piano: manipulation knowledge of objects

Two experiments investigated sensory/motor-based functional knowledge of man-made objects: manipulation features associated with the actual usage of objects. In Experiment 1, a series of prime-target pairs was presented auditorily, and participants were asked to make a lexical decision on the target word. Participants made a significantly faster decision about the target word (e.g. ‘typewriter’) following a related prime that shared manipulation features with the target (e.g. ‘piano’) than an unrelated prime (e.g. ‘blanket’). In Experiment 2, participants' eye movements were monitored when they viewed a visual display on a computer screen while listening to a concurrent auditory input. Participants were instructed to simply identify the auditory input and touch the corresponding object on the computer display. Participants fixated an object picture (e.g. “typewriter”) related to a target word (e.g. ‘piano’) significantly more often than an unrelated object picture (e.g. “bucket”) as well as a visually matched control (e.g. “couch”). Results of the two experiments suggest that manipulation knowledge of words is retrieved without conscious effort and that manipulation knowledge constitutes a part of the lexical-semantic representation of objects.     

First- and third-person approaches in implicit learning research

How do we find out whether someone is conscious of some information or not? A simple answer is “We just ask them”! However, things are not so simple. Here, we review recent developments in the use of subjective and objective methods in implicit learning research and discuss the highly complex methodological problems that their use raises in the domain.     

The logic of the stimulus

This paper examines the contribution of stimulus processing to animal logics. In the classic functionalist S-O-R view of learning (and cognition), stimuli provide the raw material to which the organism applies its cognitive processes–its logic, which may be taxon-specific. Stimuli may contribute to the logic of the organism's response, and may do so in taxon-specific ways. Firstly, any non-trivial stimulus has an internal organization that may constrain or bias the way that the organism addresses it; since stimuli can only be defined relative to the organism's perceptual apparatus, and this apparatus is taxon-specific, such constraints or biases will often be taxon-specific. Secondly, the representation of a stimulus that the perceptual system builds, and the analysis it makes of this representation, may provide a model for the synthesis and analysis done at a more cognitive level. Such a model is plausible for evolutionary reasons: perceptual analysis was probably perfected before cognitive analysis in the evolutionary history of the vertebrates. Like stimulus-driven analysis, such perceptually modelled cognition may be taxon-specific because of the taxon-specificity of the perceptual apparatus. However, it may also be the case that different taxa are able to free themselves from the stimulus logic, and therefore apply a more abstract logic, to different extents. This thesis is defended with reference to two examples of cases where animals' cognitive logic seems to be isomorphic with perceptual logic, specifically in the case of pigeons' attention to global and local information in visual stimuli, and dogs' failure to comprehend means-end relationships in string-pulling tasks.This contribution is part of the special issue “Animal Logics” (Watanabe and Huber 2006).
