Social uncertainty and interdependence: A study of resource allocation decisions in groups

Social uncertainty about the behavior of others with whom one is interdependent for rewards is hypothesized to encourage self-interested behavior and inhibit behavioral commitment to the group. This paper examines the roles of uncertainty, expectations, and feedback about other group members' contributions to the group in interdependent decision making. In the absence of feedback, resources tend to be divided between individual and group interests. Resource allocations to the group are found to increase significantly if group members receive feedback about other members' allocations, particularly if that feedback is at the individual level, not an aggregated group level. However, the effects of feedback presence and type are eliminated when group members state their expectations about other members' future contributions to the group. Implications for expectancy value theories of motivation and commitment to groups in organizations are discussed.     

The Influence of Distress on Mothers' and Fathers' Reports of Childhood Emotional and Behavioral Problems

This study examined the effect of parental distress on mothers' and fathers' reports of children's emotional and behavioral problems. The subjects were the parents of 696 children aged 10 to 11 or 14 to 15 years living in two-parent families in the community. The study utilized an extended version of the model previously employed by Fergusson, Lynskey, and Horwood (1993) to examine the impact of maternal depression on mothers' reports of children's behavior. In the present study, the extended model was used to assess the impact of distress on reports of childhood externalizing and internalizing problems obtained from both mothers and fathers. The results suggested that distress had little influence on mothers' or fathers' reports of childhood behavior problems. It is concluded that in community studies the size of any bias in mothers' and fathers' reports of childhood behavior problems due to parental distress is likely to be very small and of little clinical significance.     

Subfactors of DSM-IV Conduct Disorder: Evidence and Connections with Syndromes from the Child Behavior Checklist

Is conduct disorder (CD) as defined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV; American Psychiatric Association, 1994) a unitary entity, or do variants of CD exist? We addressed this question, using data collected from the parents of 1,669 Australian boys, aged 6–17. Parents were interviewed to assess DSM-IV Conduct Disorder (DSM-IV CD) criteria. Results revealed 2 subfactors of DSM-IV CD symptoms, made up of overt behaviors (e.g., initiating physical fights) and covert behaviors (e.g., stealing without confrontation). Ordinary least squares regressions showed the 2 CD subfactors to be significantly and uniquely predicted by Child Behavior Checklist (CBCL; T. M. Achenbach, 1991a, 1991b) syndromes labeled Aggressive Behavior and Delinquent Behavior, respectively. The results are discussed in terms of the utility of differentiating these 2 variants of CD in future editions of the DSM.     

MINDS AND MORALS

In this paper, I argue that an externalist theory of thought content provides the means to resolve two debates in moral philosophy. The first—that between judgement internalism and judgement externalism—concerns the question of whether there is a conceptual connection between moral judgement and motivation. The second—that between reasons internalism and reasons externalism—concerns the relationship between moral reasons and an agent's subjective motivational set. The resolutions essentially stem from the externalist claim that concepts can be grasped partially, and a new moral theory, which I call ‘moral externalism’, emerges.     

Who Wants to Follow the Leader? Using Personality and Work Value Profiles to Predict Preferences for Charismatic,Ideological, and Pragmatic Styles of Leading

Despite the contributions of charismatic and transformational theories, their universal applicability has recently been called into question. Dovetailing this debate is a growing interest in followers. We contribute to these discussions by examining the impact of follower individual difference profiles on preferences for charismatic, ideological, and pragmatic styles of leading. Drawing on Weber’s (1924) taxonomy of managerial authority in its reconceptualized form as the charismatic-ideological-pragmatic (CIP) model, we conducted a vignette study in which 415 working adults first completed an online survey assessing their personality and work values. Eight weeks later, a second survey asked them to read a fictional scenario about an organization and three speeches depicting each leader’s style. Participants then indicated their leader preference, which we sought to predict using their personality and work values profiles. Results of discriminant function analyses indicated certain linear combinations of personality and work values variables discriminated between participants’ leader preferences.     

Cultural Competence and School Counselor Training: A Collective Case Study

This collective case study investigated the experiences of bilingual counselors‐in‐training who assessed school‐wide cultural competence in public schools. Analysis and interpretation of data resulted in the identification of 5 themes: eye‐opening experiences, recognition of strengths, the role of school leaders, road maps for change, and empowering marginalized groups. Implications and recommendations are discussed. Este estudio de caso colectivo investigó las experiencias de consejeros bilingües en formación que evaluaron la competencia cultural institucional en escuelas públicas. El análisis e interpretación de los datos dieron como resultado la identificación de 5 temas: experiencias reveladoras, reconocimiento de puntos fuertes, el papel de los líderes académicos, hojas de ruta para el cambio y empoderamiento de grupos marginalizados. Se discuten las implicaciones y recomendaciones.     

Social Mishap Exposures for Social Anxiety Disorder: An Important Treatment Ingredient

Conventional cognitive-behavioral therapy for social anxiety disorder, which is closely based on the treatment for depression, has been shown to be effective in numerous randomized placebo-controlled trials. Although this intervention is more effective than waitlist control group and placebo conditions, a considerable number of clients do not respond to this approach. Newer approaches include techniques specifically tailored to this particular population. One of these techniques, social mishap exposure practice, is associated with significant improvement in treatment gains. We will describe here the theoretical framework for social mishap exposures that addresses the client's exaggerated estimation of social cost. We will then present clinical observations and outcome data of a client who underwent treatment that included such social mishap exposures. Findings are discussed in the context of treatment implications and directions for future research.

Effects of negative incentive shifts in food reward on rats' consumption of concurrent ethanol solutions

Frustration stress, typically operationalized as the unexpected loss of reinforcement, has been shown to engender substance use. Abrupt reductions in reinforcer magnitude likely also function as frustration stressors. These negative incentive shifts were previously shown to produce tap‐ and sweetened‐water drinking in rats. The purpose of this study was to investigate whether these shifts in food reward would occasion oral ethanol self‐administration. Nine male Long‐Evans rats operated on a two‐component multiple fixed‐ratio schedule with signaled components producing either a large (4 pellets) or small (1pellet) reinforcer. Components were pseudorandomly arranged to present 4 transitions between past and upcoming reinforcer magnitudes: small‐to‐large, small‐to‐small, large‐to‐large, and large‐to‐small (negative incentive shift). Experiment 1 investigated the effects of negative incentive shifts on consumption of concurrent, freely available 10% sucrose, 10% sucrose plus 10% ethanol, and following sucrose fading, 10% ethanol. Experiment 2 entailed continuation of schedule contingencies with a dose manipulation of 4 ethanol concentrations (0, 5, 10, and 20%) to assess dose‐dependent differences in transition‐type control and consumption. A lever‐press extinction condition was then conducted with 10% ethanol availability. In this novel model of frustration stress, negative incentive shifts prompted ethanol self‐administration at each dose investigated, whereas the other transitions did not.
