Selective search in short-term memory under ideal conditions of test stimulus categorization

It has often been claimed that short-term memory search is not selective because it takes longer to categorize the test stimulus than to search throughout the whole memory set. Four experiments investigated whether evidence for selective search can be obtained when effectively no time is required to categorize the test stimulus. Even under this favorable condition, no evidence was found for selective search of only the relevant memory subset. Therefore, the time to categorize a test stimulus cannot be the only reason why short-term memory search is not selective.     

On the analysis of psychometric functions: The Spearman-Kärber method

With computer simulations, we examined the performance of the Spearman-Kärber method for analyzing psychometric functions and compared this method with the standard technique of probit analysis. The Spearman-Kärber method was found to be superior in most cases. It generally yielded less biased and less variable estimates of the location and dispersion of a psychometric function, and it provided more power to detect differences in these parameters across experimental conditions. Moreover, the Spearman-Kärber method provided information about the skewness and higher moments of psychometric functions that is beyond the scope of probit analysis. These advantages of the Spearman-Kärber method suggest that it should often be used in preference to probit analysis for the analysis of observed psychometric functions.     

“We” are not stressed: Social identity in groups buffers neuroendocrine stress reactions

The presence of others in threatening situations can be a mixed blessing since it is not always perceived as supportive but can also impair well-being. Building on the social identity approach, we tested the idea that the presence of others has a buffering effect on neuroendocrine stress reactions only if a sense of shared social identity is evoked. Therefore, the salience of social versus personal identity was manipulated. To induce social-evaluative stress, the Trier Social Stress Test for groups (TSST-G) was employed, while in the control conditions the Placebo-TSST-G was used. As predicted, social identity salience attenuated the stress-induced cortisol reaction in the TSST-G condition. By contrast, there was no effect of identity salience in the Placebo-TSST-G conditions. These findings provide the first experimental evidence for the idea that being part of a group buffers neuroendocrine stress only if group members develop a sense of shared social identity.     

Trajectories of Attention Deficit Hyperactivity Disorder and Oppositional Defiant Disorder Symptoms as Precursors of Borderline Personality Disorder Symptoms in Adolescent Girls

Little empirical evidence exists regarding the developmental links between childhood psychopathology and borderline personality disorder (BPD) in adolescence. The current study addresses this gap by examining symptoms of attention deficit hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) as potential precursors. ADHD and BPD share clinical features of impulsivity, poor self-regulation, and executive dysfunction, while ODD and BPD share features of anger and interpersonal turmoil. The study is based on annual, longitudinal data from the two oldest cohorts in the Pittsburgh Girls Study (N = 1,233). We used piecewise latent growth curve models of ADHD and ODD scores from age 8 to 10 and 10 to 13 years to examine the prospective associations between dual trajectories of ADHD and ODD symptom severity and later BPD symptoms at age 14 in girls. To examine the specificity of these associations, we also included conduct disorder and depression symptom severity at age 14 as additional outcomes. We found that higher levels of ADHD and ODD scores at age 8 uniquely predicted BPD symptoms at age 14. Additionally, the rate of growth in ADHD scores from age 10 to 13 and the rate of growth in ODD scores from 8 to 10 uniquely predicted higher BPD symptoms at age 14. This study adds to the literature on the early development of BPD by providing the first longitudinal study to examine ADHD and ODD symptom trajectories as specific childhood precursors of BPD symptoms in adolescent girls.     

War trauma lingers on: Associations between maternal posttraumatic stress disorder,parent–child interaction,and child development

Maternal traumatization has been proposed as a risk factor for child development, but the mechanisms involved are poorly understood. This study analyzed the interrelations among maternal posttraumatic stress symptoms, parent–child interaction (emotional availability), and infants' psychosocial functioning and development among 49 asylum‐seeker and refugee mothers and their children (18–42 months). Measures included assessment of mothers' trauma and comorbid symptoms (Harvard Trauma Questionnaire: R.F. Mollica et al., 1992 ; Hopkins Symptom Checklist: L. Derogatis, R. Lipman, K. Rickels, E. Uhlenhuth, & L. Covi, 1974 ), emotional availability within parent–child interaction (Emotional Availability Scales: Z. Biringen, 2008 ), and infants' psychosocial functioning (Child Behavior Checklist: T.M. Achenbach & L.A. Rescorla, 2000 ) and development (Bayley Scales of Infant Development: B.F. van der Meulen, S.A.J. Ruiter, H.C. Spelberg, & M. Smrkovsky, 2000 ). The results show that higher levels of maternal posttraumatic stress symptoms are associated with a higher level of psychosocial problems of infants, but not with delays in their mental or psychomotor development. The results also show that higher levels of maternal posttraumatic stress symptoms are associated with higher levels of insensitive, unstructuring, or hostile, but not intrusive, parent–child interactions. Infants show lower levels of responsiveness and involvement to their traumatized mothers. Parent–child interaction did not function as a mediator between maternal trauma symptoms and infants' psychosocial functioning. Results are discussed in relation to the dyad's regulation of emotions. Results implicate a need to reestablish attunement between traumatized mothers and their nontraumatized children.     

Temporal processing within and across senses

This special issue on temporal processing within and across senses was the outcome of a two-day workshop that took place in Tübingen, Germany. The aim of the workshop and this special issue was to advance our knowledge on timing and the senses and to bring together two lines of research that have not yet interacted, those of synchrony and duration perception.     

The use of self-disclosure among Swedish psychotherapists

Although self-disclosure, when handled with discretion, is often seen as an important intervention in many psychotherapy orientations, including psychodynamic as well as humanistic and cognitive-behavioral approaches, many psychotherapists seem reluctant to use it. The frequency and type of those interventions from psychotherapists of different orientations is less well known. In this study, a random sample of Swedish psychotherapists was asked about their use of different types of self-disclosing information. The results showed that therapists with CBT orientation told their clients more about their training and about their personal ways of handling affective-relational issues. It was apparent that the trend toward more use of self-disclosure in relational psychodynamic treatment has not been accepted among a large number of psychodynamic and psychoanalytic psychotherapists in Sweden. It is recommended that psychotherapists inform their clients more about their training and in appropriate ways share more with their clients about their own relational experiences. Doing so may help enhance clients’ hope and their ability to address their ongoing difficulties.     

Ecology and Beyond

This article argues that phenomenology should investigate the phenomenon human happiness because this distinctive style of philosophizing has the potential to make a special contribution to the determination of the highest human good. This distinctive contribution is a function of the phenomenological method, which generally involves the performance of the phenomenological epoché and the execution of the transcendental reduction with respect to the acts of consciousness and their correlatively constituted objects. By means of an axiological application of the phenomenological method specifically to this fundamental ethical and practical question, it becomes possible to distinguish in a rigorous manner between what people think or feel happiness is and what it genuinely is. For example, the phenomenological approach to happiness enables people to neutralize their natural attitude toward the perceived highest good, in which it is given naively and straightforwardly, and to adopt the transcendental attitude toward it, in which it is taken critically and reflectively. As a result, all other things being equal, an application of the phenomenological method to the phenomenon human happiness enhances the prospects for an achievement of the highest human good on the part of the human agents involved in its pursuit.     

The unfolding meaning of intentionality and horizon in phenomenology

After a brief review of recent federal education legislation, in particular the No Child Left Behind Act, we present a model for educational assessment that does more than focus upon high-stakes testing. This model of educational assessment represents a mixed methods approach that school districts can adopt to assist them in becoming more proactive with respect to assessment. It utilizes both qualitative and quantitative research methods, is an example of participatory action research, and demonstrates the value of this mixed methods approach to assessment. Utilizing this model gives a district a sense of empowerment and control and, most important, provides a better understanding of the real issues and challenges that a school district faces. It provides school districts with an accurate assessment of the quality their schools by utilizing a comprehensive and longitudinal perspective that accurately reflects how successful the district is in educating its students.
