Are the interpersonal and identity disturbances in the borderline personality disorder criteria linked to the traits of affective instability and impulsivity?

This study examines the degree to which two putative biologically influenced personality traits, affective instability and impulsive aggression, are associated with some of the interpersonal and intrapsychic disturbances of borderline personality disorder (BPD) and with choice of defense mechanism. In a sample of 152 personality disorder patients, affective instability and impulsive aggression were measured. Defense mechanisms were assessed in 140 of these patients using the Defensive Style Questionnaire (DSQ). The correlations between the traits of affective instability and impulsive aggression and the eight DSM-III-R criteria for borderline personality disorder and 20 DSQ defenses were examined. Affective instability was significantly correlated with the DSM-III-R criteria of identity disturbance, chronic emptiness or boredom, inappropriate anger, suicidality, and the affective instability criteria. It also was associated with the defenses of splitting, projection, acting out, passive aggression, undoing, and autistic fantasy. Impulsive aggression was related to unstable interpersonal relationships, inappropriate anger and impulsiveness and with the defense of acting out. It was negatively correlated with the defenses of suppression and reaction formation. A number of the interpersonal and experiential disturbances and defense mechanisms that are features of BPD are associated with the traits of affective instability and impulsive aggression among patients with personality disorders.     

Quality and Ecology of Adversity as Common Mechanisms of Risk and Resilience

This paper proposes common mechanisms to explain the effects of adversities and of resources that promote resilience. Adversities threaten the satisfaction of basic human needs and the acquisitions of competencies to carry out valued social roles. Adversities can also be characterized in terms of their ecological properties of occurrence in time, and place. Resilience resources at the individual, microsystem and macro levels reduce the negative effects of adversities through their effects on satisfaction of basic human needs and their effects on the occurrence of adversities. The effects of resilience resources are described as preventive, protective and promotive. Implications are presented for the development of interventions to promote resilience.     

Influence of single and multiple onset distractors on visual search for singleton targets

In three experiments, we examined attentional and oculomotor capture by single and multiple abrupt onsets in a singleton search paradigm. Subjects were instructed to move their eyes as quickly as possible to a color singleton target and to identify a small letter located inside of it. In Experiment 1, taskirrelevant sudden onsets appeared simultaneously on half the trials with the presentation of the color singleton target. Response times (RTs) were longer when onsets appeared in the display regardless of the number of onsets. Eye-scan strategies were also disrupted by the appearance of the onset distractors, although the proportion of trials on which the eyes were directed to the onsets was the same regardless of the number of onsets. In Experiment 2, we manipulated the time of presentation of two taskirrelevant onsets in order to further examine whether multiple onsets would be attended and fixated prior to attending a color singleton target. Again, subjects made a saccade to a task-irrelevant onset on a substantial proportion of trials prior to fixating the target. However, saccades to the second onset were rare. Experiment 3 served as a replication of Experiment 1 but without the requirement for subjects to move their eyes to detect and identify the singleton target. The RT results were consistent with those in Experiment 1; dual onsets had no larger an effect on response speed than single onset distractors. These data are discussed in terms of the interaction between top-down and bottom-up control of attention and the eyes.     

Indices of response bias in the same-different experiment

Thesame-different experiment is popular for assessing perceptual performance, including the performance of people with neuropsychological deficits. Although the measurement of accuracy with this experiment is now well understood, the measurement of response bias remains problematic. Reformulating the decision space for the experiment can yield new bias indices that are analogous to, but numerically different from, those of the more familiar yesno experiment. Isobias curves that show how hit rate covaries with false alarm rate for constant bias but varying accuracy are presented for eight indices, and best-fitting parameters of the isobias functions are determined for a set of experimental data. The theoretical status of the bias indices and their relation to other formulations are reviewed.     

Validating a new process tracing method for decision making

In this paper, we describe two experiments in which we assessed the validity of phased narrowing, a new process tracing technique designed to help researchers better understand multiattribute evaluation processes. Specifically, in Experiment 1 we examined the distribution of choices across successive decision stages and the attitudes and perceptions of the decision maker. In Experiment 2, we examined a variety of process data generated via a computerized information monitoring program called Mouse-Trace. Comparisons, in all cases, are made between experimental conditions that do and do not require decision makers to narrow their choices across successive stages. Taken together, the data indicate that there is little evidence to doubt the validity of a less restrictive version of phased narrowing which allows subjects to choose their own number of options to include at each stage. These results are encouraging for researchers who plan to use the technique to study decision making in its natural context.     

Down syndrome: cognitive phenotype

Down syndrome is the most prevalent cause of intellectual impairment associated with a genetic anomaly, in this case, trisomy of chromosome 21. It affects both physical and cognitive development and produces a characteristic phenotype, although affected individuals vary considerably with respect to severity of specific impairments. Studies focusing on the cognitive characteristics of Down syndrome were reviewed, and while performance in most areas could be predicted based upon overall intellectual disability, relative weaknesses were consistently found to be associated with expressive language, syntactic/morphosyntactic processing, and verbal working memory. This profile of uneven deficits could result from a failure to develop typically automatic processing for speech perception and production, and this possibility is discussed along with its implications for intervention.     

Rebuilding the tower of Babel: a revised nomenclature for the study of suicide and suicidal behaviors. Part 2: Suicide-related ideations, communications, and behaviors

A revised and refined version of the O'Carroll et al. (1996) nomenclature for suicidology is presented, with a focus on suicide‐related ideations, communications, and behaviors. The hope is that this refinement will result in the development of operational definitions and field testing of this nomenclature in clinical and research settings. This revision would not have been possible without the international collaboration and dialogue addressing the nomenclature of suicidology since the O'Carroll et al. nomenclature appeared in 1996. Although it is doubtful that we will ever be able to construct universally unambiguous criteria to comprehensively characterize suicidal behaviors (and, overall, firmly establish the intention behind them), for scientific clarity it would be highly desirable that the set of definitions and the associated terminology be explicit and generalizable.

Evidence-based practices project for suicide prevention

Suicide continues to be a serious public health problem. In response to this problem, a myriad of suicide prevention programs have been developed and employed across the United States. Unfortunately, the effectiveness of many of these programs is unknown because they have not been evaluated using rigorous methods. The Evidence-Based Practices Project (EBPP) for suicide prevention was created in 2002 to identify and promote evidence-based suicide prevention programs. In this paper the process and outcomes of the initial EBPP project within the context of the broader evidence-based movement are described, and the EBPPs creation of a best practice registry for suicide prevention is previewed.

Common and distinct factors in decision making under ambiguity and risk: A psychometric study of individual differences

The relation between decision making under ambiguity and risky decision making was examined. In Studies 1 and 2, choices under ambiguity were measured for a large sample receiving an Ellsberg-type Ambiguity-Probability Tradeoff Task. Participants with extreme scores were recruited for Part 2 of each study which consisted of a risky decision making task (Study 1) or a series of decisions under ambiguity in “real life” scenarios (Study 2). Despite a time gap of up to 2 months, individual differences in scores on Part 1 predicted scores on Part 2. In Study 3 participants received in a single session several risky decision making tasks, several measures of decision making under ambiguity, and several personality scales related to uncertainty and decision making style. Taken together, the findings support the existence of a stable dispositional trait to reduce uncertainty in decision making but also task-specific differences related to gains and losses.
