about the authors

After tobacco and alcohol, marijuana is the most frequently used and abused substance. Its use is particularly prevalent among young adults, aged 18 to 25. This study examines the role strain plays in chronic (as opposed to recreational) marijuana use. Three theoretical perspectives are included in this analysis: General Strain Theory, Social Learning, and Self Control. Data from the 2001 National Household Survey of Drug Abuse are used to determine the relative effects of peers (social learning), strain (general strain theory), and favorable attitudes toward risk-taking (self control). Data is divided into subsamples on the basis of gender. Logistic Regression analysis suggests that males are more likely to be chronic users, and that psychological strain, social learning, and low self control are significant factors associated with chronic use. Furthermore, strain has a stronger effect on chronic use for minority group members, as does a propensity to risky behavior. Social learning has a stronger effect on nonminority group members. All factors have a stronger significant effect on female chronic marijuana use than on male marijuana use (except for the demographic variable education). Policy implications and suggestions for future research are also included.     

Economic strain and suicide risk: a qualitative analysis

Research at the individual level on economic strain and suicide has focused on unemployment; yet it remains unclear how unemployment and other economic strains actually affect suicide risk for the individual. In the present study Agnew's (1992, 2002), General Strain Theory was applied to a qualitative analysis of case files. Strain issues assessed include the role of goal blockage, economic loss, noxious work environments, anticipated strain, strain clusters, and vicarious strain in the generation of suicide risk. Data are from 62 cases of suicide involving economic strain from the files of an urban county medical examiner's office. The cases were classified into strain categories. Suicide risk was related to all categories of strain; however, economic strains were typically comorbid with additional strains in the genesis of suicide. Key auxiliary strains included anticipated loss of a home place, loss of a car, noxious social relationships, medical problems, death of loved ones, and involvement with the criminal justice system. Some evidence was found linking economic strain to the suicides of nonimpoverished persons. Economic strain and suicide would especially benefit by testing additional hypotheses on strain comorbidity. Unemployment combined with an anticipated eviction from one's home is recommended as a particular point of departure for future work.     

Children balance theories and evidence in exploration, explanation, and learning

We look at the effect of evidence and prior beliefs on exploration, explanation and learning. In Experiment 1, we tested children both with and without differential prior beliefs about balance relationships (Center Theorists, mean: 82 months; Mass Theorists, mean: 89 months; No Theory children, mean: 62 months). Center and Mass Theory children who observed identical evidence explored the block differently depending on their beliefs. When the block was balanced at its geometric center (belief-violating to a Mass Theorist, but belief-consistent to a Center Theorist), Mass Theory children explored the block more, and Center Theory children showed the standard novelty preference; when the block was balanced at the center of mass, the pattern of results reversed. The No Theory children showed a novelty preference regardless of evidence. In Experiments 2 and 3, we follow-up on these findings, showing that both Mass and Center Theorists selectively and differentially appeal to auxiliary variables (e.g., a magnet) to explain evidence only when their beliefs are violated. We also show that children use the data to revise their predictions in the absence of the explanatory auxiliary variable but not in its presence. Taken together, these results suggest that children's learning is at once conservative and flexible; children integrate evidence, prior beliefs, and competing causal hypotheses in their exploration, explanation, and learning.     

purging behavior in a sample of college females: a research note on general strain theory and female deviance

Tests of theories of deviance tend to focus on criminality, delinquency, or types of deviance more typically engaged in by males. Prototypical female deviance has been largely ignored. This article reports the findings from a pilot study of female deviance. Using a sample of 96 college women, we examine the utility of General Strain Theory to explain one prototypically female type of deviant behavior, purging. We explore the relationship of strain variables to purging, mediated through negative affect. Two forms of negative affect, anger and depression, are included in the model. Our findings suggest that the relationship is complex, with an interaction between anger and depression. Anger is associated with purging at high levels of depression only. The preliminary findings, when viewed in conjunction with prior research, suggest that different negative affective states may be associated with different types of deviance outcomes, and that typically "female" or self-directed types of deviance may result from the interaction of anger and depression.     

Domain-creating constraints

The contributions to this special issue on cognitive development collectively propose ways in which learning involves developing constraints that shape subsequent learning. A learning system must be constrained to learn efficiently, but some of these constraints are themselves learnable. To know how something will behave, a learner must know what kind of thing it is. Although this has led previous researchers to argue for domain-specific constraints that are tied to different kinds/domains, an exciting possibility is that kinds/domains themselves can be learned. General cognitive constraints, when combined with rich inputs, can establish domains, rather than these domains necessarily preexisting prior to learning. Knowledge is structured and richly differentiated, but its "skeleton" must not always be preestablished. Instead, the skeleton may be adapted to fit patterns of co-occurrence, task requirements, and goals. Finally, we argue that for models of development to demonstrate genuine cognitive novelty, it will be helpful for them to move beyond highly preprocessed and symbolic encodings that limit flexibility. We consider two physical models that learn to make tone discriminations. They are mechanistic models that preserve rich spatial, perceptual, dynamic, and concrete information, allowing them to form surprising new classes of hypotheses and encodings.     

A Theoretical Examination of Immigrant Status and Substance Use among Latino College Students

ABSTRACT

Drawing on survey data from a sample of Latino college students, we examine the generalizability of social learning theory, general strain theory, social bond theory, and self-control theory to a Latino population and consider how these four theories can elaborate on the relationship between immigrant status and substance use. We find that social learning and general strain provide the most robust explanations of substance use across four outcomes. Also, third-plus generation respondents generally reported more substance use than first-generation respondents. Our findings suggest that this latter trend is due mostly to varying effect sizes in social learning by immigrant status.     

Addressing a Divide in the Conceptualization of the Gender-Crime Relationship: A Comparative Test of Gender and Sex Using General Strain Theory

While criminology has long recognized the impact of gender on crime, many criminological theories continue to measure sex rather than socially constructed gender identities. Research has also struggled to directly compare these measures within a theoretical context. This study examines the impact of sex and gender identity variables using the framework of General Strain Theory. A total of 1,457 college students were surveyed on measures of General Strain Theory, biological sex, gender identity, and a range of deviant behaviors. Findings indicate that gender identity produced a stronger predictive model of deviance than biological sex, and suggest a means for research to account for gender when studying deviance.     

Critical Reflection,Self-Knowledge,and the Emotions

Abstract

Drawing on recent cognitive theories of the emotions, this article develops an account of critical reflection as requiring emotional flexibility and involving the ability to envisage alternative reasons for action. The focus on the role of emotions in critical reflection, and in agents' resistance to reflection, suggests the need to move beyond an introspective to a more social and relational conception of the process of reflection. It also casts new light on the intractable problem of explaining how oppressive socialisation impairs the capacity for autonomy.     

Externalizing Disorders in Adolescence Mediate the Effects of Maternal Depression on Substance Use Disorders

Maternal depression has been linked to increased risk of substance use disorders (SUDs) in offspring. Cross-sectional studies have identified relationships among maternal depression, externalizing disorders and SUDs, but no longitudinal examination of causality has been undertaken. In order to address this gap in the literature, depression and externalizing disorders at or prior to age 15 were tested as mediators of the relationship between maternal depression and SUDs diagnosed between ages 16 and 20 in a sample of 702 Australian youth (363 women) using path models. Mothers’ and fathers’ substance diagnoses and earlier onset of substance abuse in youth were controlled for in all analyses. Consistent with previous work, maternal depression predicted SUDs between ages 16 and 20. An indirect effect of maternal depression through youth externalizing disorders diagnosed by age 16 was detected for alcohol and cannabis use disorders, but not drug disorders. Early adolescent depression was not a mediator of the relationship between maternal depression and any of the substance outcomes measured. To our knowledge, this study is the first to examine depression and externalizing disorders in early adolescence as mediators of the effect of maternal depression on psychopathology in later adolescence. Further work is needed to understand how family environment and genetic factors may explain the mediation by externalizing disorders.

Reversal Learning Deficits in Criminal Offenders: Effects of Psychopathy,Substance use,and Childhood Maltreatment History

Deficits in reinforcement learning are presumed to underlie the impulsive and incorrigible behavior exhibited by psychopathic criminals. However, previous studies documenting reversal learning impairments in psychopathic individuals have not investigated this relationship across a continuous range of psychopathy severity, nor have they examined how reversal learning impairments relate to different psychopathic traits, such as the interpersonal-affective and lifestyle-antisocial dimensions. Furthermore, previous studies have not considered the role that childhood maltreatment and substance use may have in this specific cognitive deficit. Using a standard reversal learning task in a sample of N = 114 incarcerated male offenders, we demonstrate a significant relationship between psychopathy severity and reversal learning errors. Furthermore, we show a significant interaction between psychopathy and childhood maltreatment, but not substance use, such that individuals high in psychopathy with an extensive history of maltreatment committed the greatest number of reversal learning errors. These findings extend the current understanding of reversal learning performance among psychopathic individuals, and highlight the importance of considering childhood maltreatment when studying psychopathy.     

When, what, and how much to reward in reinforcement learning-based models of cognition

Reinforcement learning approaches to cognitive modeling represent task acquisition as learning to choose the sequence of steps that accomplishes the task while maximizing a reward. However, an apparently unrecognized problem for modelers is choosing when, what, and how much to reward; that is, when (the moment: end of trial, subtask, or some other interval of task performance), what (the objective function: e.g., performance time or performance accuracy), and how much (the magnitude: with binary, categorical, or continuous values). In this article, we explore the problem space of these three parameters in the context of a task whose completion entails some combination of 36 state-action pairs, where all intermediate states (i.e., after the initial state and prior to the end state) represent progressive but partial completion of the task. Different choices produce profoundly different learning paths and outcomes, with the strongest effect for moment. Unfortunately, there is little discussion in the literature of the effect of such choices. This absence is disappointing, as the choice of when, what, and how much needs to be made by a modeler for every learning model.     

A study of drug discipline policies in secondary schools

Little is known about how secondary schools respond to substance abuse in terms of policies, practices, or procedures. A comprehensive survey of St. Louis County public secondary schools conducted in Fall 1979 suggests that many school officials are more punitive than their juvenile court counterparts when handling incidents of drug use. A range of exclusionary discipline policies is the predominant sanction invoked against students who violate established substance-abuse policies. Questionnaire results indicate the existence of due process violations and the differential enforcement of alcohol and marijuana offenses. Furthermore, unlike the criminal justice system, many schools do not consider the amount or type of drug use or students' prior behavior as criteria for determining an appropriate disciplinary sanction. Several areas for the revision of substance-abuse policies in schools are suggested, including: acknowledging alcohol as a potentially dangerous drug, assuring that school sanctions are individually tailored to pupils' best interests and needs, developing in-school alternative programs to suspension, and providing for the total compliance of substance-abuse policies with students' legal rights.     

Unpacking the Racial Disparity in Crime from a Racialized General Strain Theory Perspective

ABSTRACT

Criminologists have long theorized the relationship between race and crime using traditional criminological theories, suggesting that Blacks simply experience more factors conducive to crime than Whites. Race scholars have criticized this “add and stir” approach and, instead, argue for race-based explanations. Racialized General Strain Theory (RGST) is the first traditional approach to address this call to action. To date, however, little research has fully assessed RGST’s propositions. Using the Project on Human Development in Chicago Neighborhoods, we find mixed support for RGST. Findings also suggest racial differences in experiences and responses to strain are much more complicated than originally theorized.     

A Test of Three Alternative Hypotheses Regarding the Effects of Early Delinquency on Adolescent Psychosocial Functioning and Substance Involvement

This study compared alternative hypotheses (from general deviance, life course, and developmental psychopathology perspectives) regarding the effects of early adolescent delinquency on psychosocial functioning in family, school, and peer contexts, and on alcohol use. Analyses also examined parent-child negative affective quality, prosocial school orientation, and peer substance use as possible direct predictors of problem substance use. Participants in this longitudinal study, extending from age 11 to age 18, were 429 rural teens (222 girls) and their families. Path model comparisons supported the tenability of a partial mediation model that included mediating pathways and a direct effect of delinquency on alcohol use, as hypothesized by developmental psychopathology. A supplemental analysis controlling for the stability of the family, school, and peer variables revealed that delinquency had less pervasive direct effects on, and a nonsignificant indirect effect through, changes in the mediators over time. Results also showed that peer substance use was a direct positive predictor of problem use.     

Analysis of systems influencing renal hemodynamics and sodium excretion. I. Biochemical systems theory

In this article we present a new methodology—Biochemical Systems Theory and Analysis—as an alternative to traditional parametric statistical procedures for investigating differences between risk groups in a population. We review the systems theory and how it can be used to represent a model of processes influencing renal hemodynamics and sodium (Na⁺) excretion. We also discuss the potential for new measures of the biology of common diseases that can emerge from a synergism between systems theory and population-based statistical approaches. This work was supported in part by grants from the Public Health Service, RO1-HL30428, R01-HL39107 and General Clinical Research Center Grant RR0585.     

Reasons for (prior) belief in Bayesian epistemology

Bayesian epistemology tells us with great precision how we should move from prior to posterior beliefs in light of new evidence or information, but says little about where our prior beliefs come from. It offers few resources to describe some prior beliefs as rational or well-justified, and others as irrational or unreasonable. A different strand of epistemology takes the central epistemological question to be not how to change one’s beliefs in light of new evidence, but what reasons justify a given set of beliefs in the first place. We offer an account of rational belief formation that closes some of the gap between Bayesianism and its reason-based alternative, formalizing the idea that an agent can have reasons for his or her (prior) beliefs, in addition to evidence or information in the ordinary Bayesian sense. Our analysis of reasons for belief is part of a larger programme of research on the role of reasons in rational agency (Dietrich and List, Nous, 2012a, in press; Int J Game Theory, 2012b, in press).     

The systems approach — A. Bogdanov and L. von Bertalanffy

We undertake the comparison between Ludwig von Bertalanffy's General Systems Theory and Alexandr Bodganov's Tektology as two theories proposing a holistic interpretation of reality and claiming to solve problems which are unsolvable via conventional philosophic and scientific theories and methodologies. Basic misunderstandings by some Soviet authors regarding the nature of these theories — especially in the case of Tektology — are pointed out. The comparison is made in what concerns the general origins and purposes of the theories, their approaches to the problem of organization, their treatment of mathematics and their understanding of the cybernetic concept of regulation.We contend that Tektologycontains — some 15 years earlier — all the basic concepts which will be later developed by the General Theory of Systems. As we shall see, Tektology is the ultimate expansion of any theory of systems. This fact is widely ignored in contemporary specialized literature.We finally contend that both Tektology and the General Systems Theory are a sign of the times. A holistic secular monism is a respectable alternative to the failure of contemporary science and philosophy in guiding the life of men, in providing araison d'être for human existence. However, we do not explore the soundness of this alternative.
