Introduction and application of the multiscale coefficient of variation analysis

Quantifying how patterns of behavior relate across multiple levels of measurement typically requires long time series for reliable parameter estimation. We describe a novel analysis that estimates patterns of variability across multiple scales of analysis suitable for time series of short duration. The multiscale coefficient of variation (MSCV) measures the distance between local coefficient of variation estimates within particular time windows and the overall coefficient of variation across all time samples. We first describe the MSCV analysis and provide an example analytical protocol with corresponding MATLAB implementation and code. Next, we present a simulation study testing the new analysis using time series generated by ARFIMA models that span white noise, short-term and long-term correlations. The MSCV analysis was observed to be sensitive to specific parameters of ARFIMA models varying in the type of temporal structure and time series length. We then apply the MSCV analysis to short time series of speech phrases and musical themes to show commonalities in multiscale structure. The simulation and application studies provide evidence that the MSCV analysis can discriminate between time series varying in multiscale structure and length.     

Neuroticism, negative affect, and negative affect instability: Establishing convergent and discriminant validity using ecological momentary assessment

Few investigations have examined the role of affective instability within a broad model of general personality functioning. The present study employed self-report and ecological momentary assessments (EMA) to examine the relations between self-reported Five-Factor Model Neuroticism, EMA average negative affect, and EMA negative affect instability. Results suggest that Neuroticism and negative affect instability are related yet distinct constructs, and that Neuroticism better represents average negative affect across time. Results also suggest that negative affect instability is related to low Agreeableness and specific externalizing facets of Neuroticism, such as Angry Hostility and Impulsiveness. The implications of these findings and potential areas for future research are discussed.     

Clinical Differences Exist Between Patients Fulfilling the 1988 and 1994 Case Definitions of Chronic Fatigue Syndrome

Despite the existence of 2 different case definitions for chronic fatigue syndrome, little data exist to evaluate how each performs. We evaluated the symptom patterns of patients fulfilling either the more demanding 1988 or the less demanding 1994 case definitions of Chronic Fatigue Syndrome over an 11-year period from 1991 to 2001. Factor analysis identified 3 factors: muscular–skeletal, viral, and sleep:memory symptom factors accounting for significant variation in the data. Further discriminant analysis showed that the first 2 factors and a self-reported measure of decrease in activity alone gave 91% accuracy in the placement of patients into their respective case definitions. This analysis did indicate that both case definitions were capturing the same broad group of patients. However, the patients in the 1994 group do not endorse infectious-type symptoms as often or to the same degree of severity as those in the 1988 group. This may mean that infection as a cause of CFS is more likely in patients fulfilling the earlier, more demanding case definition.     

Learning social attitudes: children's sensitivity to the nonverbal behaviors of adult models during interracial interactions

White children show marked ingroup race preferences and a relative devaluation of Black people. The origin of these early interracial attitudes is to a large extent still unclear. The studies here test the possibility that preschool-aged children are particularly sensitive to the nonverbal behaviors performed by White adults during interracial interactions. In Study 1, children were shown a video displaying an interaction between a White and a Black adult. Across conditions, the White adult's verbal behaviors were either friendly or neutral, whereas his nonverbal behaviors showed either easiness (e.g., closeness, high eye contact) or uneasiness (e.g., distance, avoidance of eye contact). Results revealed that participants shaped their attitudes toward the Black target accordingly, independently from the White adults' verbal behaviors. Study 2 replicated the basic findings and demonstrated that the observed effects generalized to other Black targets. Results are discussed in relation to current approaches to understanding the formation of racial attitudes among children.     

Do Young Children Really Learn Best From the use of Direct Address in Children’s Television?

A large body of research has considered children’s novel word learning from video; however, no known work has compared children’s novel word learning from an educational television show in which the character speaks directly to the child (participatory cues) and a show in which the child overhears two characters speaking to one another (third-party joint attention). Using two professionally produced videos that mimic contemporary children’s television shows, we conducted a 2-condition experiment (N = 73) to examine under which condition children were better able to learn a novel word. Results indicated a main effect of condition and age: children in the participatory cues condition and older children demonstrated greater word learning than children in the third-party joint attention condition and younger children. There was an interaction between age and condition, but only among children between the ages of 28.20 and 41.46 months. These findings demonstrate that the participatory cues model, typically used in children’s television programming, is a better model to use to promote children’s word learning. These findings run counter to a similar study that used stimulus videos that did not mimic a children’s program, finding that the third-party joint attention condition was more effective.

The empirical status of empirically supported psychotherapies: assumptions, findings, and reporting in controlled clinical trials

This article provides a critical review of the assumptions and findings of studies used to establish psychotherapies as empirically supported. The attempt to identify empirically supported therapies (ESTs) imposes particular assumptions on the use of randomized controlled trial (RCT) methodology that appear to be valid for some disorders and treatments (notably exposure-based treatments of specific anxiety symptoms) but substantially violated for others. Meta-analytic studies support a more nuanced view of treatment efficacy than implied by a dichotomous judgment of supported versus unsupported. The authors recommend changes in reporting practices to maximize the clinical utility of RCTs, describe alternative methodologies that may be useful when the assumptions underlying EST methodology are violated, and suggest a shift from validating treatment packages to testing intervention strategies and theories of change that clinicians can integrate into empirically informed therapies.     

Parental bonding and personality pathology assessed by clinician report

The present study focused on the link between parental bonding and personality pathology. We developed a clinician-report version of the Parental Bonding Instrument (PBI; Parker, Tupling, and Brown, 1979), which 203 clinicians applied to a randomly selected patient in their care. The goal of the study was to examine the reliability and validity of a clinician-report PBI, and to provide a preliminary examination of the relation between personality disorder (PD) symptoms and parental bonding in a national sample of patients in treatment in the community. Factor analysis yielded two factors (parental rejection/care and parental overprotection) for each parent, which had high internal consistency (coefficient alphas all >.80). The factor structure of the clinician-report measure strongly resembled the factor structure of the widely used self-report instrument. Parental bonding as assessed by clinician report showed coherent patterns of association with PD diagnoses, which resembled those found in other samples. Maternal rejection/care showed a particular link to borderline PD (BPD), and remained a significant predictor of BPD along with sexual abuse and physical abuse in multiple regression analysis. These data, along with others from recent studies using clinicians as informants, suggest that clinicians can provide reliable and valid data when their observations are quantified using psychometrically sound instruments. Clinician-report methods may provide a useful complement to studies of personality disorders that rely primarily on self-reports or structured interviews.     

ERP correlates of form and rhyme letter tasks in impaired reading children: a critical evaluation.

Event-related potentials (ERPs) were obtained from 15 electrode sites in six average and six impaired reading children, 12 years of age, during visual letter discrimination tasks. Subjects responded to target letters with an enclosed area in the form task and to letters that rhymed with "e" in the rhyme task. Response accuracy was similar between the groups. Reaction time was relatively longer for the impaired group during the rhyme task. At lateral sites, condition differences were evident as greater negative shifts in the rhyme task than the form at 170 and 470 ms as well as a delayed late positivity for the rhyme. In terms of reading ability, the average readers' ERPs were more negative than those of the impaired group at 270 and 450 ms. Inter-hemispheric variations were also seen between the groups, with the average readers more negative than the impaired readers at right hemisphere sites. Contrary to expectations, group differences in the ERP did not vary substantially as a function of condition, and task demands were evaluated in view of these findings.     

Developments in cognitive neuroscience: II. Implications for theories of transference

An integration of psychoanalytic theory with contemporary developments in cognitive neuroscience offers a useful perspective on long-standing controversies about the nature of transference, and a better understanding of the precise mechanisms by which transferential processes occur. Contemporary psychoanalytic views of transference are reviewed, and the many processes that constitute transference are described. Two issues that have emerged in different guises for several decades-the role of the analyst in eliciting transference, and the nature of "real" and "transferential" components of the therapeutic relationship-are reconsidered in the light of concepts such as connectionist networks. Although a useful analytic stance is one that allows the patient's enduring dynamics to dominate the analytic field, it is suggested, anonymity is neither a cognitive possibility nor the driving force behind most transference reactions, and the distinction between "real" and "transferential" perceptions is one of therapeutic interest, not of mechanism. Certain features of the analytic situation make some dynamics more likely than others to enter the treatment relationship, notably those related to authority, intimacy and attachment, and sexuality. Transference reactions are best understood as constructed from a combination of the patient's enduring dispositions to react in particular ways under particular conditions; features of the analytic situation and of the analyst; and interactions between patient and analyst. These reactions do not unfold ineluctably from the patient's mind in the consulting room, nor are they cognitive constructions of the patient-analyst dyad or co-constructions of relatively equal partners exerting their influence on the analytic field.
