Hierarchical organization of a reference system in newborn spontaneous movements

In this paper, we studied spontaneous newborn movements regarding the coordination of the four limbs, arms and legs, from a dynamic perspective. We used the method of recurrence plots to analyse the kinematic data from audiovisual recordings of neonates. We identified temporal and spatial synchronization of the four limbs that resulted in high recurrence patterns of biomechanical reference configurations. Furthermore, we identified transitions between linear and nonlinear epochs in the movement behavior of newborns on different time scales by means of recurrence quantification analysis. Results are discussed in the context of the concept of a structural hierarchy, in which different time scales correspond to hierarchical levels of organization.     

Marital satisfaction and depression: a replication of the Marital Discord Model in a Latino sample

The Marital Discord Model of Depression maintains that marital discord is an important antecedent in the development of depression. Although empirical evidence supports this premise, none of this research has been done with Latinos. The purpose of this study was to test the longitudinal relationship between marital satisfaction and depression among 99 Brazilian women. Using structural equation modeling, results indicated that marital satisfaction was a strong predictor of depression 2 years later. Marital satisfaction was also related to cooccurring depression. These results provide evidence that the Marital Discord Model of Depression is an appropriate theoretical model for the conceptualization of marital discord and depression with Latina women and suggest the potential utility of using couples therapy for treating depression among this population.     

On-task distractors associated with totball baseball games: a preliminary study

Two totball baseball leagues in southern Louisiana were monitored to judge what type of parental involvement yielded the highest on-task behaviors among participants. 39 children ages 3 to 5 years participated in 3- or 4-inning baseball games with parents on the field. In the Parent on Bases League, a parent stood on first, second, and third base only. In the Parent with Every Child League, a parent stood next to every child on the field. Children were observed on the field at three different dates at 1-min. intervals during the first two innings of one game in both leagues. On-task behaviors were defined as standing in the correct field position and watching the ball. Off-task behaviors consisted of sitting, rolling on the field, talking to a coach or parent, and not watching the ball. A statistically significant difference in the percent of time children spent on-task favored the Parents on Bases League (75.7) versus the other league (50.3). Having fewer parents on the field in these baseball games kept players on-task more effectively than having a parent with each child.     

Moving from “I” to “We”: A Grounded Theory Analysis of Couple Therapy with Liver Patients and Their Partners

Prior research indicates that couples who cope with chronic illness from a relational “we” orientation experience more positive outcomes than couples that cope individually; however, little prior research identifies clinical processes that promote reciprocity or how societal gender processes are involved. This grounded theory analysis of 25 videotaped therapy sessions with six heterosexual couples coping with chronic liver disease (LD) used a feminist-informed relational lens to focus on the clinical processes involved in shifting from an individual to a relational orientation. Findings identified three contextual barriers to attaining a “we orientation”: (a) autonomy discourse, (b) illness-related power, and (c) gendered power. Analysis detailed therapist actions that decreased the impact of barriers to reciprocity and fostered relational coping. Clinical implications attend to complex intersections among gender, caregiving, and contextual barriers to reciprocity.     

Learning under stress: A role for the neural cell adhesion molecule NCAM

Stress is known to be a potent modulator of brain function and cognition. While prolonged and/or excessive stress generally exerts negative effects on learning and memory processes, acute stress can have differential effects on memory function depending on a number of factors (such as stress duration, stress intensity, timing and the source of the stress, as well as the learning type under study). Here, we have focused on the effects of ‘acute’ stress, and examined the literature attending to whether the “source of stress” is ‘intrinsic’ (i.e., when stress is originated by the cognitive task) or ‘extrinsic’ (i.e., when stress is induced by elements not related to the cognitive task). We have questioned here whether the neural cell adhesion molecule of the immunoglobulin superfamily (NCAM) contributes to the neurobiological mechanisms that translate the effects of these two different stress sources into the different behavioral and cognitive outcomes. NCAM is a cell adhesion macromolecule known to play a critical role in development and plasticity of the nervous system. NCAM and its post-translational modified form PSA-NCAM are critically involved in mechanisms of learning and memory and their expression levels are known to be highly susceptible to modulation by stress. Whereas available data are insufficient to conclude as to whether NCAM mediates extrinsic stress effects on learning and memory processes, we present systematic evidence supporting a key mediating role for both NCAM and PSA-NCAM in the facilitation of memory consolidation induced by intrinsic stress. Furthermore, NCAM is suggested to participate in some of the bidirectional effects of stress on memory processes, with its enhanced synaptic expression involved in facilitating stress actions while its reduced expression being related to impairing effects of stress on memory function.     

Investigating the Awareness of Remembering

ABSTRACT— There is a marked lack of consensus concerning the best way to learn how conscious experiences arise. In this article, we advocate for scientific approaches that attempt to bring together four types of phenomena and their corresponding theoretical accounts: behavioral acts, cognitive events, neural events, and subjective experience. We propose that the key challenge is to comprehensively specify the relationships among these four facets of the problem of understanding consciousness without excluding any facet. Although other perspectives on consciousness can also be informative, combining these four perspectives could lead to significant progress in explaining a conscious experience such as remembering. We summarize some relevant findings from cognitive neuroscience investigations of the conscious experience of memory retrieval and of memory behaviors that transpire in the absence of the awareness of remembering. These examples illustrate suitable scientific strategies for making progress in understanding consciousness by developing and testing theories that connect the behavioral expression of recall and recognition, the requisite cognitive transactions, the neural events that make remembering possible, and the awareness of remembering.     

Self‐Enhancement in a Job Search Context

The purpose of this study was to examine the role of self‐enhancement in a job search context. Based on previous theoretical and empirical research on positive illusions and core self‐evaluations, we examined the relationships among core self‐evaluations, self‐enhancement, perceived job alternatives, and job search behaviors. Participants in two different studies were students attending a career fair at a university in the southwestern United States to look for a job. Results showed that self‐enhancement is positively related to preparatory job search and mediates the relationship between core self‐evaluations and perceived job alternatives. The implications of this study are discussed.     

TRANSFER OF AVERSIVE RESPONDENT ELICITATION IN ACCORDANCE WITH EQUIVALENCE RELATIONS

The present study investigates the transfer of aversively conditioned respondent elicitation through equivalence classes, using skin conductance as the measure of conditioning. The first experiment is an attempt to replicate Experiment 1 in Dougher, Augustson, Markham, Greenway, and Wulfert (1994), with different temporal parameters in the aversive conditioning procedure employed. Match‐to‐sample procedures were used to teach 17 participants two 4‐member equivalence classes. Then, one member of one class was paired with electric shock and one member of the other class was presented without shock. The remaining stimuli from each class were presented in transfer tests. Unlike the findings in the original study, transfer of conditioning was not achieved. In Experiment 2, similar procedures were used with 30 participants, although several modifications were introduced (formation of five‐member classes, direct conditioning with several elements of each class, random sequences of stimulus presentation in transfer tests, reversal in aversive conditioning contingencies). More than 80% of participants who had shown differential conditioning also showed the transfer of function effect. Moreover, this effect was replicated within subjects for 3 participants. This is the first demonstration of the transfer of aversive respondent elicitation through stimulus equivalence classes with the presentation of transfer test trials in random order. The latter prevents the possibility that transfer effects are an artefact of transfer test presentation order.     

Three preparatory studies for promoting implementation of outpatient schema therapy for borderline personality disorder in general mental health care

ObjectiveThree studies were conducted to prepare for the implementation of Schema Therapy (ST) for Borderline Personality Disorder (BPD) in general mental healthcare settings. Two were surveys to detect promoting and hindering factors, one was a preliminary test of a training program in ST.MethodsIn 2004, a diagnostic analysis of factors promoting and hindering implementation of a new treatment for BPD was conducted among both managers (n = 23) and therapists (n = 49) of 29 Dutch mental healthcare institutes through a written survey (Study 1). Next, a training program, including a set of DVDs displaying the major therapeutic techniques, was developed and tested among eight therapists. The training program was evaluated by the participants. After the training, three independent raters evaluated therapists' adherence and competence, viewing videos of the therapists completing structured role-plays (Study 2). In 2008, a second written survey was conducted in 22 mental health institutes to study factors for future nationwide implementation of ST (Study 3).ResultsBoth surveys indicated that the situation in most institutes was favorable for implementing a new effective treatment, as participants were not satisfied with the existing treatments, had suitable professional backgrounds, worked in settings with (B)PD-oriented care programs, and expressed a need for change. The surveys yielded clear results for promoting or hindering successful implementation of ST. Promoting factors included scientific evidence for the effectiveness of the treatment, structural changes in the patient's personality, rapidly noticeable effects for the patient, low drop-out rates and a favorable cost-effectiveness. Possible barriers included implementation mandated unilaterally by management, choosing ST based on financial or organizational needs, extending implementation over a lengthy period of time and providing telephone support by therapists beyond office hours. The eight-day training program received very positive ratings. After the training, therapists were rated as sufficiently adherent and competent applying ST to treat BPD patients, with peer supervision and supervision recommended as a supplement to the training.ConclusionThis study showed that the situation in 2005 was advantageous to start implementation of ST. Evaluation of the training and the achieved competence scores of trainees concluded that the training program was a good basis for training therapists in ST. Outcome of the survey in 2008 demonstrated that there was a clear interest for implementation of ST for BPD patients in the future.     

Illness behavior: prediction by symptoms, the Grossarth-Maticek and Eysenck Personality Types, neuroticism, life events, coping, health locus of control, social support, and attribution style

A study was carried out with 501 persons to analyze the predictive capacity of various psychosocial variables-symptom perception, neuroticism, Personality Types 2 and 4 of Grossarth-Maticek and Eysenck, beliefs about health, social support, or certain coping styles-on two health-related behaviors: the frequency of visits to the doctor and self-medication. The results were analyzed by two structural equation models that revealed that some of the variables have direct effects on the behaviors, whereas other variables, such as attribution style, coping styles, or the impact of the stressors, have indirect effects via the reported symptoms or neuroticism. In addition, self-medication and the frequency of health service visits are independent of each other, which shows that their determinants are different. It is concluded that to address these factors in the two health indicators, it is also necessary to take in account the psychosocial variables considered herein.
