A Multinomial Model to Assess Fluency and Recollection in a Sequence Learning Task

We suggest that well-formedness judgements in conjunction with L.L. Jacoby's (1991) process dissociation procedure and an appropriate measurement model can be used to obtain measures of implicit and explicit sequence knowledge. We introduce a new measurement model designed specifically for the sequence learning task. The model assumes that sequence identification is based on recollection, perceptual or motor fluency, systematicity detection, and guessing. The model and the application of the process dissociation procedure were empirically evaluatedusing auditory eventsequences. In Experiment 1, the parameterreflecting recollection was higher in an intentional than in an incidental learning condition. Experiment 2 showed that random sequences interspersed among the systematic sequences during the acquisition phase may change this pattern of results. A manipulation of processing fluency in Experiment 3 was reflected in the appropriate model parameter. In sum, the new measurement model and the application of the process dissociation procedure appear to be useful tools in sequence learning research.     

Understanding How Participation in a Consumer-Run Organization Relates to Recovery

The goal of this study was to examine how different types of participation in a consumer-run organization (CRO) are related to recovery. More specifically, this study uses structural equation modeling to examine the relative impact of empowering and socially supportive participation experiences on progress towards recovery among 250 CRO members from 20 CROs. An empowering participation experience refers to involvement in leadership roles and contribution to organizational functioning. A socially supportive participation experience refers to social involvement in mutually supportive friendships with intimacy and sharing. Results indicate that both types of participation are associated with recovery, although a socially supportive participation experience maintains a stronger relationship with recovery than an empowering participation experience. Findings are consistent with the idea that CROs should encourage both types of participation. Drawing from over ten years of experience supporting CROs, the discussion section explores several strategies CROs can use to foster empowering and socially supportive participation experiences.     

The effects of a self‐observation‐based meditation intervention on acceptance or rejection of the other

Research has demonstrated the many benefits of mindfulness training programmes for individual health and well‐being. This study, however, explored whether mindfulness training might have effects on intergroup interaction. We tested the effects of a self‐observation‐based mindfulness course on several dimensions of acceptance of the other (i.e., non‐judgement, non‐reaction and observation). An initial study test a mindfulness course training (N = 197). A second study then tested its effect on intergroup relationships (N = 120). A control group was used in both studies, and the subjects were tested before and after the course. Results indicate that participation in the course favoured intergroup acceptance of the other and suggest that mindfulness training represents a useful educational method for reducing social discrimination.     

Suburban Subversions: Swingers and the Sexual Revolution

This article discusses how the 1965 Supreme Court Griswold v. Connecticut decision, which narrowly defined marital privacy to include only monogamous and reproductive sex, contextualizes depictions of suburban swingers. Focusing on narratives of swingers in John Updike’s Couples and Rick Moody’s novel The Ice Storm, issues of privacy and surveillance complicate and problematize marital sexuality, making swinging difficult to sustain. The confluence of restrictive legal and liberal cultural discourses and their influence on marital relationships are depicted in the texts examined in this article, which offer insight into the problem of marital privacy. Updike’s novel Couples depicts swinging as a revolutionary act: in one sense, swinging upends the post war, conservative marital structure, and in another, it results in a “revolution,” a circuit back to where the couples began. This article then turns to Rick Moody’s 1994 novel The Ice Storm, which offers a retrospective look at suburban sexual excess and the negative impact this behavior had on the children of the privileged suburban enclave. The confluence of different legal, social, and cultural pressures on married couples to maintain normative sexual behavior cannot be overcome in these texts.     

Depression and anxious apprehension distinguish frontocingulate cortical activity during top-down attentional control

A network consisting of left dorsolateral prefrontal cortex (LDLPFC) and dorsal anterior cingulate cortex (dACC) has been implicated in top-down attentional control. Few studies have systematically investigated how this network is altered in psychopathology, despite evidence that depression and anxiety are associated with attentional control impairments. Functional MRI and dense-array event-related brain potential (ERP) data were collected in separate sessions from 100 participants during a color-word Stroop task. Functional MRI results guided ERP source modeling to characterize the time course of activity in LDLPFC (300-440 ms) and dACC (520-680 ms). At low levels of depression, LDLPFC activity was indirectly related to Stroop interference and only via dACC activity. In contrast, at high levels of depression, dACC did not play an intervening role, and increased LDLPFC activity was directly related to decreased Stroop interference. Specific to high levels of anxious apprehension, higher dACC activity was related to more Stroop interference. Results indicate that depression and anxious apprehension modulate temporally and functionally distinct aspects of the frontocingulate network involved in top-down attention control.     

Binary recursive partitioning: Background,methods, and application to psychology

Binary recursive partitioning (BRP) is a computationally intensive statistical method that can be used in situations where linear models are often used. Instead of imposing many assumptions to arrive at a tractable statistical model, BRP simply seeks to accurately predict a response variable based on values of predictor variables. The method outputs a decision tree depicting the predictor variables that were related to the response variable, along with the nature of the variables' relationships. No significance tests are involved, and the tree's ‘goodness’ is judged based on its predictive accuracy. In this paper, we describe BRP methods in a detailed manner and illustrate their use in psychological research. We also provide R code for carrying out the methods.     

Posttraumatic stress disorder, traumatic brain injury, and suicide attempt history among veterans receiving mental health services

History of posttraumatic stress disorder (PTSD) or traumatic brain injury (TBI) has been found to increase risk of suicidal behavior. The association between suicide attempt history among veterans with PTSD and/or TBI was explored. Cases (N = 81) and 2:1 matched controls (N = 160) were randomly selected from a Veterans Affairs Medical Center clinical database. PTSD history was associated with an increased risk for a suicide attempt (OR = 2.8; 95% CI: 1.5, 5.1). This increased risk was present for those with and without a history of TBI. Results support incorporating PTSD history when assessing suicide risk among veterans with and without TBI.     

Town vs. gown: a direct comparison of community residents and student mock jurors

The use of students as mock jurors in the majority of legal psychology studies on jury behavior has been criticized (e.g., Bray & Kerr, 1979; Diamond, 1997). This study examined the degree to which student mock jurors' decisions were generalizable to those of real jurors. The participants of the study included 297 jury-eligible university students and 297 volunteers from the venire in the same community as that in which the students resided. All participants viewed one of six versions of a videotaped criminal trial. The defendant testified in English or in Spanish. In addition, the race of defendant was varied. Three bilingual individuals served as defendants with one appearing to be of northern European origin, one of Latino background, and one of African origin. Dependent variables included verdict and, for those who found the defendant guilty, the number of years to which he should be sentenced, and whether he should be fined. Student mock jurors differed reliably from their community counterparts on several demographic characteristics. However, the two groups had mixed results in relation to decision-making tasks. There was no difference in individual verdict preferences, but the students' sentence recommendations were more punitive. These results are interpreted in the context of the generalizability of mock juror studies.     

The Definition of Moral Dilemmas: A Logical Confusion and a Clarification

This discussion note deals with Jurriaan de Haan's paper The Definition of Moral Dilemmas: A Logical Problem (Ethical Theory and Moral Practice 4(3), 2001, pp. 267–284). In the first, critical part I will point out a confusion in the logical analysis of the paper in question. In the second, constructive part I will indicate how the analysis of moral dilemmas should proceed within the framework of a possible world semantics.
