COMPOSITION AND COINCIDENCE

Many philosophers say that the same atoms may compose at once a statue and a lump of matter that could outlive the statue. I reject this because no difference between the statue and the lump could explain why they have different persistence conditions. But if we say that the lump is the statue, it is difficult to see how there could be any human beings. I argue that this and analogous problems about material objects admit only of solutions that at least appear to be radically at odds with our ordinary thinking.     

Simulation of neural sets

A program has been written for the PDP-8/I computer which simulates the behavior of 64 model neurons which may be connected together to form a functional neural net. The simulation includes provisions for studying the possible mechanisms of learning in real systems. Operation of the net requires inputs from either a robot or a robot simulator program and output from the net serves as input to such a robot, so that the entire system investigates the Behavior of an organism and its brain in interaction with an environment.     

Beyond Discrete Categories: Studying Multiracial,Intersex, and Transgender Children Will Strengthen Basic Developmental Science

Developmental research on social categorization has overwhelmingly focused on perceptions about and experiences of individuals who are clear or prototypical members of discrete and usually dichotomous social categories. For example, studies of social categorization, stereotyping, prejudice, and social identity have generally explored how children reason about others who are gender-typical boys or girls or monoracial White or Black children. Similarly, research participants have generally been gender-typical and monoracial. However, our efforts to build theories that account for the true range of variation require acknowledging the increasing visibility of children who do not fit into these discrete categories and raise the question of whether existing theories can capture the dynamics that arise for them. Focusing on race and gender/sex, the social categories that have received the most attention in the developmental literature, we review research that has gone beyond simple dichotomies by including multiracial, gender-nonconforming, or intersex children, either as the targets of social perception or as participants themselves. We argue that this emerging work reveals problematic assumptions built into our theories and methods and highlights the value of building a more inclusive science.     

Terrorism Outside the Proverbial Vacuum: Implications for the Moral Context

Prior research has found that terrorists are not susceptible to certain and severe countermeasures. One possibility is that, instead, deterrence is relative. Based on this premise and inspired by situational action theory’s conceptualization of the “moral context,” this research proposes that there are circumstances that influence both moral norms and their enforcement. We hypothesize that one set of circumstances is that of high profile terrorist attacks, which in turn should decrease the hazard of future incidents. We find mixed support for our hypotheses, but maintain that it has important implications for policy.     

Examination of Life Satisfaction,Child Maltreatment Potential and Substance Use in Mothers Referred for Treatment by Child Protective Services for Child Neglect and Substance Abuse: Implications for Intervention Planning

There is evidence to suggest mothers who are served by child protective service agencies are relatively dissatisfied in their lives, leading some investigators to conclude life dissatisfaction may be associated with child maltreatment. To assist in better understanding this relationship the Life Satisfaction Scale for Caregivers (LSSC) was psychometrically developed in a sample of 72 mothers who were referred for behavioral treatment for child neglect and substance abuse by caseworkers from a local child protective service agency. The LSSC was developed to assess mothers’ happiness in nine domains (family, friendships, employment/work, spirituality/religion, safety, sex life/dating, ability to avoid drugs, ability to avoid alcohol, control over one’s own life). Results indicated two factors that appeared to be relevant to Social Satisfaction and Safety and Control Satisfaction. Higher satisfaction scores on both of these scales were negatively associated with child maltreatment potential and substance use at baseline (i.e., positive urinalysis test). Mothers who exposed their children to substances in utero or in infancy (a distinct type of child neglect) were found to report higher satisfaction scores on the LSSC than other types of child neglect. Hispanic-American, African-American, and Caucasian women reported similar levels of life satisfaction. Application of the LSSC as a non-stigmatizing, wellness-focused instrument is discussed within the context of intervention planning.
