Immediate and delayed memory tasks: A computerized behavioral measure of memory, attention, and impulsivity

The Immediate and Delayed Memory Task (IMT/DMT), a variant of the Continuous Performance Test (CPT), is a new software package designed to be a flexible research tool for the study of attention, memory, and impulsivity. This package allows researchers to determine the design to be used during a testing session and to manipulate many of the parameters. It features two components: the IMT and the DMT, both of which present sequential 2- to 7-digit stimuli with variable presentation rates and intertrial intervals. Subjects respond to identically matched stimuli presented consecutively, spanning a brief period of time (IMT), or to stimuli spanning a greater period of time (during which intervening stimuli to be ignored appear; DMT). Task complexity can be adjusted to suit applications for both children and adults. Preliminary studies have demonstrated that these laboratory tasks are sensitive to group differences, produce stable baselines of performance, and are sensitive to drug-induced performance decrements.     

Outcome studies of family therapy in child and adolescent depression

There is surprisingly little good-quality evidence for the effectiveness of family systemic interventions with child and adolescent depression given the prevalence of depression and the demonstrated association with a range of family factors. What studies there are suggest the possibility of family therapy being an effective intervention but more research is needed before firm conclusions may be drawn. Family interventions may be more effective in children than in adolescents and where other family members are depressed. It is possible that family interventions continue to bring about improvement in symptoms after cessation of treatment. What research there is evaluates older structural models of therapy: there is a real need for more evaluation of newer models of practice.     

Effectiveness of family therapy: a meta-analysis

The effectiveness of family therapy is assessed in a meta-analysis of 19 studies. At post-treatment, the average patient with family therapy is better off than 76% of the patients with an alternative treatment, a minimal treatment or no treatment. This effect is comparable to that assessed of other psycho-therapies at post-treatment. Our data suggest, that the effect of family therapy increases during the first year after treatment, but that the effect may diminish sharply 18 months after the end of therapy. However, more studies with extended follow-ups will be needed before firm conclusions about the long-term effectiveness of family therapy can be advanced.     

Single-Case Experimental Designs in Family Therapy Research: Limitations and Considerations

Recent authors have encouraged the use of single-case experimental design in family therapy research. However, several issues related to the application of these designs have not been addressed. The present article suggests that the applicability of single-case methods to family therapy research may be limited. The first issue raised is the general lack of adequate dependent measures of family interaction that fulfill the requirements of the single-case experimental designs. Suggestions for development of appropriate measures are given. Second, the necessary reliance on relatively weak single-case designs often allows only relatively weak conclusions. Finally, the strategy of beginning the single-case study of family functioning and family therapy in laboratory settings is suggested.     

Managing data for integrity: Policies and procedures for ensuring the accuracy and quality of the data in the laboratory

Management of the research data is an extremely important responsibility of the Principal Investigator (PI) and other members of the research team. Without accurate data, no worthwhile conclusions can be drawn from the research study. Integrity in data management is critical to the success of the research group and to public trust in the research outcomes. One of the primary responsibilities of the PI is to provide proper training to the junior members of the lab. This effort can be buttressed by institutional data policies that are implemented at the group level. Extensive and frequent guidance in good research practices by the PI and other senior research staff is critical to the proper training of new scientists.     

Axiomatic Extensions of IMT3 Logic

In this paper we characterize, classify and axiomatize all axiomatic extensions of the IMT3 logic. This logic is the axiomatic extension of the involutive monoidal t-norm logic given by ¬φ³ ∨ φ. For our purpose we study the lattice of all subvarieties of the class IMT3, which is the variety of IMTL-algebras given by the equation ¬(x³) ∨ x ≈ ?, and it is the algebraic counterpart of IMT3 logic. Since every subvariety of IMT3 is generated by their totally ordered members, we study the structure of all IMT3-chains in order to determine the lattice of all subvarieties of IMT3. Given a family of IMT3-chains the number of elements of the largest odd finite subalgebra in the family and the number of elements of the largest even finite subalgebra in the family turns out to be a complete classifier of the variety generated. We obtain a canonical set of generators and a finite equational axiomatization for each subvariety and, for each corresponding logic, a finite set of characteristic matrices and a finite set of axioms.     

Enduring interest in perceptual ambiguity: alternating views of reversible figures

Research favoring the so-called bottom-up and top-down classes of explanations for reversible figures that dominated the literature in last half of the 20th century is reviewed. Two conclusions are offered. First, any single-process model is extremely unlikely to be able to accommodate the wide array of empirical findings, suggesting that the "final" explanation will almost certainly involve a hybrid conceptualization of interacting sensory and cognitive processes. Second, the utility of distinguishing between 2 components of the observer's experience with reversible figures is emphasized. This distinction between the observer's ability to access multiple representations from the single stimulus pattern (ambiguity) and the observer's phenomenal experience of oscillation between those representations (reversibility) permits the literature to be segregated into useful categories of research that expose overlapping but distinctive cortical processes.     

Digging Deeper: An Object Relations Couple Therapy Update

Over the past two decades, neurobiology research has added clarity to the process of emotional and behavioral change. In turn, this has led to endorsement of interventions that appear to be most helpful in individual and couple therapy. In addition to research on emotional dysregulation, contemporary studies have focused on the construction of meaning and its relevance to interpersonal relationships. According to Lisa Barrett, Richard Lane, and others, the brain references concepts to rapidly arrive at the most probable conclusions. Encoded experience and memory fragments guide this process and are vital in understanding partners' emotional responses. These findings support an object relations perspective that emphasizes the importance of past relational experiences that inform the present. This is particularly relevant in work with couples, as each individual's beliefs, expectations, and capacity for intimacy are invariably tied to earlier relationships. Research findings on memory reconstruction provide a basis for interventions that can add to the existing treatment approach, as it is suggested that working in a specific way with emotionally based memories has the potential to modify and reduce their predictive power and ability to unleash beliefs and behaviors that work against intimacy. The therapist who is informed by emerging neuroscience research can better uncover and actively work with memories that may be compromising a couple's relationship.     

Interactive effect of long-term mental stress and cardiac stress reactivity on carotid intima-media thickness: the Cardiovascular Risk in Young Finns study

The present study examined the interaction between vital exhaustion and cardiac reactivity and recovery on preclinical atherosclerosis assessed by carotid intima-media thickness (IMT) in young men and women. We measured heart rate (HR), respiratory sinus arrhythmia (RSA), and pre-ejection period (PEP) in response to mental arithmetic and speech tasks. Vital exhaustion and carotid IMT were also measured. Significant associations were observed for men aged 28-37 years, but not for men aged 22-25 years, nor for women in these age groups. It was shown that, among highly exhausted men in the older age group, lower HR reactivity was related to greater IMT. Our results also imply that, among non-exhausted men in this age group, slow HR and RSA recovery after acute stress predicted higher IMT. These results suggest that long-term stress as assessed by vital exhaustion is a risk only if it has resulted in ineffective cardiac stress reactivity. Autonomic imbalance resulting from chronic stress may be the common mechanism linking vital exhaustion and cardiac responsiveness to an increased risk of atherosclerosis.     

Statistics and ethics in medical research

Ethical conduct is an essential component in research, especially in medical research. Statistical methods for design and analysis are powerful research tools if used properly. Abuse of these principles and methods are just as unethical as other laboratory or clinical misconduct. Inadequate research design can produce worthless results and thus wastes effort and valuable resources. For clinical research, patient resources are wasted. Inappropriate analysis of data can also produce misleading results and conclusions. For clinical research, inferior therapy might be given to patients as a consequence. These ethical concerns can have implications for and affect the individuals responsible for the statistical design and analysis. Examples are provided which illustrate some possible abuses and inappropriate pressures.     

Individual Marital Therapy — Have Reports of your Death been Somewhat Exaggerated?

In this reply to Wells and Giannetti's critique of our earlier reviews of research in family therapy, we demonstrate that the sense of absolute certainty with which they reappraise and dismiss as useless the studies we reviewed on individual marital therapy is unjustified. We also consider the implications of their critique and the conclusions they derive from it for public policy and clinical practice. Though we acknowledge the appropriateness of certain aspects of their critique, we continue to hold to our original position that, for now, there is ample empirical warrant for considering conjoint therapy to be the treatment of choice for marital problems.     

Wie wirksam sind psychoanalytisch orientierte Therapie und Verhaltenstherapie bei Persönlichkeitsstörungen?

This meta-analysis adresses the effectiveness of psychodynamic therapy and cognitive-behavioral therapy in personality disorders. Included were 14 studies of psychodynamic therapy and 11 studies of cognitive-behavioral therapy from 1974 to 2001. There is evidence that both psychodynamic therapy and cognitive-behavioral therapy are effective treatments of personality disorders. As the number of studies that could be included in this meta-analysis was limited, the conclusions that can be drawn are only preliminary. Further studies which examine specific forms of psychotherapy in specific types of personality disorders using criteria of core psychopathology are necessary. Both longer periods of treatment and follow-up studies should be included.     

Whose voice are we hearing,really?

This article, written from the position of someone who has lived experience of therapy for ‘psychosis’ and an interest in participation, explores the degree to which qualitative research truly conveys the voice and perspective of research participants. By exploring five papers focused on diverse experiences of psychotherapy, from the perspective of clients and therapists, it draws out some of the tensions inherent in making interpretations and connections within research papers and the impact this may have on the quality of any conclusions drawn. Finally, it makes some suggestions for ways of meaningfully involving research participants in the process and argues for an ongoing dialogue to prevent our own assumptions and theoretical frameworks from obscuring the importance of this involvement to improve the quality of future research.     

Re-visioning clinical research: gender and the ethics of experimental design

Since modern medicine is based substantially in clinical medical research, the flaws and ethical problems that arise in this research as it is conceived and practiced in the United States are likely to be reflected to some extent in current medicine and its practice. This paper explores some of the ways in which clinical research has suffered from an androcentric focus in its choice and definition of problems studied, approaches and methods used in design and interpretation of experiments, and theories and conclusions drawn from the research. Some examples of re-visioned research hint at solutions to the ethical dilemmas created by this biased focus; an increased number of feminists involved in clinical research may provide avenues for additional changes that would lead to improved health care for all.     

On the failure to eliminate hypotheses in a conceptual task

This investigation examines the extent to which intelligent young adults seek (i) confirming evidence alone (enumerative induction) or (ii) confirming and discontinuing evidence (eliminative induction), in order to draw conclusions in a simple conceptual task. The experiment is designed so that use of confirming evidence alone will almost certainly lead to erroneous conclusions because (i) the correct concept is entailed by many more obvious ones, and (ii) the universe of possible instances (numbers) is infinite.

Six out of 29 subjects reached the correct conclusion without previous incorrect ones, 13 reached one incorrect conclusion, nine reached two or more incorrect conclusions, and one reached no conclusion. The results showed that those subjects, who reached two or more incorrect conclusions, were unable, or unwilling to test their hypotheses. The implications are discussed in relation to scientific thinking.     

The Process of Systemic Change in Filial Therapy: A Phenomenological Study of Parent Experience

This phenomenological study represents the first qualitative exploration of parents’ experiences of the process of filial therapy from a systemic lens. Filial therapy is a treatment approach that teaches parents how to conduct weekly thirty minute play times with their target child at home in an effort to improve the parent–child relationship. Previous research has focused almost exclusively on the impact of this model on this relationship; however, the results from this focus group study (n = 8) indicate several relational shifts that occur within the greater family and societal contexts and suggest potential reasons for treatment gain maintenance over time.     

What causes birth order-intelligence patterns? The admixture hypothesis, revived.

Recent evidence shows that the relation between birth order and intelligence is not the same in cross-sectional and within-family data. This simple empirical observation invalidates the conclusions from hundreds of previous birth order studies that relied on cross-sectional data. Simultaneously, the empirical foundation disappears from underneath theories like dilution and the confluence model that use explanatory processes occurring within the family. A theory proposed almost 25 years ago--the admixture hypothesis--effectively accounts for these empirical patterns. In this article, the author describes why birth order is of such intense interest to both parents and researchers (the birth order trap), discusses past birth order-intelligence patterns, shows that the admixture hypothesis accounts for those patterns, and reframes the original argument to support future productive research efforts.     

Measuring impulsivity in adolescents with serious substance and conduct problems

Adolescents with substance use and conduct disorders have high rates of aggression and attention deficit hyperactivity disorder (ADHD), all of which have been characterized in part by impulsivity. Developing measures that capture impulsivity behaviorally and correlate with self-reported impulsivity has been difficult. One promising behavioral measure, however, is a variant of the continuous performance test, the Immediate Memory Test/Delayed Memory Test (IMT/DMT). The authors showed significant group differences between adolescents in treatment for serious substance and conduct problems and community controls on impulsivity measures, both behavioral and self-report, as well as on aggression and problem behavior measures. Furthermore, the IMT/DMT correlated significantly with self-reported impulsivity. In summary, the IMT/DMT may be an effective behavioral measure of impulsivity in adolescents.     

Using human inquiry groups in counselling research

The nature of human inquiry groups and their use in counselling research are explored. A key feature of such a group is that the details of what is researched and how it is researched are decided by the group rather than by the researcher alone. Human inquiry groups proceed through a process of cycling. The first stage involves group members gathering together to agree on the nature and the methodology of the research and on the action to be taken. The next two stages involve taking the agreed action and fully experiencing it. Finally, group members reflect together on the research so far, including drawing conclusions and initiating further research cycles. The value of human inquiry as a qualitative methodology for counselling research is considered, including a comparison between the role of the human inquiry researcher and that of the counsellor. The initiator of a human inquiry group may well make use of counselling and group-work skills. Possible problems include role conflict, collusion, how to avoid the human inquiry group turning into a therapy group, and other validity issues. The key question of how to analyse the data produced by such a group is examined. The grounded-theory approach of Glaser and Strauss is considered as one way to analyse human inquiry data. Potential difficulties with such an analysis are explored and the use of a bricolage is presented as one possible solution. Human inquiry is seen to be an important and innovative approach to counselling research which is particularly appropriate for exploratory studies.
