THE MODAL ARGUMENT FOR A PRIORI JUSTIFICATION

Kant famously argued that, from experience, we can only learn how something actually is, but not that it must be so. In this paper, I defend an improved version of Kant's argument for the existence of a priori knowledge, the Modal Argument , against recent objections by Casullo and Kitcher. For the sake of the argument, I concede Casullo's claim that we may know certain counterfactuals in an empirical way and thereby gain epistemic access to some nearby, nomologically possible worlds. But I maintain that our beliefs about metaphysical necessities still cannot be justified empirically. Furthermore, I reject Casullo's deflationary thesis about the significance of such justification. Kitcher's most troublesome objection is that we can gain any modal justification whatsoever through testimony , i.e. in an experiential way. This can be countered by distinguishing between productive sources of justification, like perception, and merely reproductive sources, like testimony. Thus, some productive a priori source will always be needed somewhere. ¹     

Behavioral Characteristics of DSM-IV ADHD Subtypes in a School-Based Population

From an ethnically diverse sample of 2,744 school children, 221 attention deficit hyperactivity disorder (ADHD) [123 (4.5%) predominantly inattentive (IA), 47 (1.7%) predominantly hyperactive/impulsive (HI), and 51 (1.9%) combined type (C)] were identified using teacher ratings on a Diagnostic and Statistical Manual of Mental Disorders (4th ed.) (DSM-IV) symptom checklist. Subjects were compared to 221 controls on teacher ratings of behavioral, academic, and social functioning. The results revealed relatively independent areas of impairment for each diagnostic group. The IA children were impaired in all areas, but were rated as displaying more appropriate behavior and fewer externalizing problems than HI or C children. The HI group displayed externalizing and social problems, but was rated as no different than controls in learning or internalizing problems. The C group demonstrated severe and pervasive difficulties across domains. These findings support the validity of the DSM-IV ADHD subtypes; all ADHD groups demonstrated impairment relative to controls, but show different patterns of behavioral characteristics.     

Health locus of control and self-esteem as related to adolescent health behavior and intentions

A health behavior and attitudes questionnaire was administered to 246 fifth-grade and 265 sixth-grade students during class time. The questions included 20 children's health locus of control (CHLC) items reported by Parcel and Meyer (1978), 17 children's self-esteem (CSE) items modified from those reported by Coopersmith (1967), and questions concerning past and current behavior and future intentions with respect to cigarette smoking, alcohol use, and marijuana use. The results indicate that the relationships between dimensions of children's health locus of control and self-esteem and their behaviors and intentions are not large enough to suggest that intervention programs directed at the prevention of detrimental health behaviors focus on the enhancement of self-esteem or the internal locus of control. An appropriate test of the efficacy of such an approach requires a longitudinal rather than a cross-sectional study, monitoring changes in the levels of self-esteem and health locus of control and associated changes in health behavior.     

Separation anxiety in mothers of latency-age fearful children

The hypothesis that mothers of children who have symptoms indicative of separation anxiety are themselves separation-anxious was tested by scoring mothers' TAT themes for separation concerns. The stories of 15 mothers of fearful children were compared to the stories of 26 mothers of children manifesting behavior disorders and 21 mothers of children having had no psychiatric contact. Different kinds of separation concerns were found to differentiate the groups of mothers. The stories of mothers of fearful children expressed significantly more concerns about abandonment and rejection and more often expressed a desire to stay near the loved one; the mothers of children with behavior disorders were found to tell significantly more stories with nurturance-succorance themes. The results lend support to the theory of anxious attachment in that mothers of fearful children seem to share the same concerns that have been ascribed to their children. On the other hand, it seems that separation anxiety may not be a unidimensional construct as different components seem to be more relevant to some symptom clusters than to others.     

Somatization, psychiatric disorder, and stress in utilization of ambulatory medical services

Examined the prediction from Mechanic's (1972) attribution theory of somatization that somatizers who are under stress will overuse ambulatory medical services. Two hundred fourteen volunteer patients from university ambulatory care clinics completed the Diagnostic Interview Schedule and the Life Experiences Inventory. We examined somatization, psychiatric diagnoses, and life stress-and the interaction of these factors-in predicting frequency of medical visits during the preceding year, after controlling for need (active medical problems) and predisposing factors. As hypothesized, life stress interacted with somatization in predicting number of medical visits; somatizers who were under stress made more visits to the clinics than did nonsomatizers or somatizers who were not under stress. Although stress affected somatizers most, stress was predictive of increased medical utilization for all patients. These results suggest that psychological services intended to reduce overutilization of outpatient medical services might best focus on stress reduction and be most beneficial to somatizers.     

Holding points of view does not amount to knowledge

I argue that knowing and having points of view are fundamentally different epistemic states if we assume that having justified true beliefs is necessary for knowledge. Knowers necessarily possess justified true beliefs, but persons holding points of view may, for example, lack justification, have false beliefs, or both. I examine these differences and expose other crucial differentiating patterns between the structure of knowledge and points of view that make the latter more likely to lead to disagreements. I hypothesize that these patterns remain invariant in alternative views of knowledge like contextualism as long as we preserve the classical structure. Yet there is much research to be done on the multiple and contrasting properties that emerge if we consider non-classical analyses of knowledge and points of view.     

Who has to act? A qualitative exploration of emerging adults' critical consciousness during the COVID-19 pandemic

The COVID-19 pandemic and violence against people of Color during 2020 brought troubling racial inequities to the forefront of American discourse. In line with the Critical Consciousness (CC) and Social Justice Youth Development (SJYD) frameworks, emerging adults may have developed their capacity for critical reflection, motivation, and action against systemic inequities. We drew from interviews with 27 emerging adults (ages 18–23) across the US, and used thematic analysis to explore differences in their reflections, motivations to act, and actions based on their racial/ethnic identification. We found nuanced variability in their critical reflections based on self, social, or global awareness and experiences of marginalization. White and Asian emerging adults used vague language or expressed feeling their reflections were insufficient. Black and Latinx emerging adults emphasized the importance of education and raising awareness. Although all emerging adults took action based on a sense of duty, few engaged in critical action; decisions to take in-person action varied based on whether they viewed racism or COVID-19 as a greater threat. Findings demonstrate that emerging adults' experiences of racialization may have related to their CC development. We share implications for community psychologists conducting antiracist research addressing White fragility and dismantling racial hierarchy.
