Resiliency and Recovery: Lessons From the Asian Tsunami and Hurricane Katrina

Separated by continents and cultures, survivors of the Asian tsunami and Hurricane Katrina share a common bond in their extreme trauma and ensuing struggles. The authors discuss and illustrate core ideas based on the commonalities derived from the experiences of women survivors of these two disasters. Separados tanto por continentes como culturas, los supervivientes del tsunami asiático y el huracán Katrina comparten el vínculo común de su enorme trauma y las dificultades subsiguientes. Los autores discuten e ilustran las ideas fundamentals basándose en las similitudes derivadas a partir de las experiencias de las mujeres que sobrevivieron a ambos desastres.     

Relative Influence of Professional Counseling Journals

The authors used social network analysis of citation data to study the flow of information and relative influence of 17 professional counseling journals. Although the Journal of Counseling & Development ranked very highly in all measures of journal influence, several division journals emerged as key players in the flow of information within the counseling profession. Results highlight the many facets of journal influence and the fallacy of using single measures, such as journal impact factor, to rank professional counseling journals.     

Response inhibition in adults and teenagers: spatiotemporal differences in the prefrontal cortex

Inhibition is a core executive function reliant on the frontal lobes that shows protracted maturation through to adulthood. We investigated the spatiotemporal characteristics of response inhibition during a visual go/no-go task in 14 teenagers and 14 adults using magnetoencephalography (MEG) and a contrast between two no-go experimental conditions designed to eliminate a common confound in earlier studies comparing go with no-go trials. Source analyses were performed using an event-related beamformer algorithm with co-registered individual structural MRIs. Performance was controlled to be similar across subjects. Analyses of MEG data revealed bilateral prefrontal activity in the inhibitory condition for both age groups, but with different spatiotemporal patterns: around 300ms after stimulus onset in middle frontal gyri in teenagers vs. around 260ms in inferior frontal gyri in adults. Moreover, the inhibition of a prepotent motor response showed a stronger recruitment of the left hemisphere in teenagers than in adults and of the right hemisphere in adults than in teenagers. These findings provide high-resolution temporal and spatial information regarding response inhibition in adolescents compared to adults, independent of motor components and performance differences.     

Psychometric and CT scan measurements in a case of crossed aphasia in a dextral

A case of crossed aphasia with lesion deep to the right supramarginal gyrus was studied to determine (1) if this patient behaved similar to patients with the same lesion site in the left hemisphere, (2) if visuospatial deficits were present, and (3) if the CT scan asymmetries were similar to those of other right-handers. Speech and language skills were similar to those patients with similar lesions in the left hemisphere. Visuospatial and arithmetic deficits were similar to those described after right-hemisphere and left-hemisphere damage. CT scan asymmetries were atypical. These results provide behavioral and neuroradiological confirmation of atypical hemispheric dominance.     

Blood phobia—beware

In every day life, many people complain that they are afraid of the sight of blood. Stories of trainee medical doctors fainting on first witnessing an operation abound. Many people turn away from films of operations. Despite this, there are few accounts of the treatment of patients presenting with blood phobia as a main complaint. Standard texts on phobias (e.g. Marks, 1969; Rachman, 1974) do not mention it, nor do texts on behavioural treatment (e.g. Yates, 1970). The purpose of this short report is to describe the treatment of a long-standing, circumscribed blood phobia in a 16 yr old boy, and to draw attention to some special considerations surrounding the treatment of blood phobic patients.     

The "short-long" reaction time effect in duration programming

The programming processes concerned with response duration were studied in a precueing and in a priming reaction time (RT) paradigm. Participants had to produce a motor response of a specified duration as soon as possible after a response signal (RS) preceded by a warning signal (WS), which could deliver information on 2 response parameters (duration and effector). In Experiment I (precueing; N = 12), 3 effectors (the right hand, the left hand, or the knees) and 3 durations (.7, 2.5, or 5.5 s) were contrasted. Two responses differing in their biomechanical features were required in 2 blocks of trials: Subjects had to accurately time the duration of either a sustained button press or an interval between 2 brief presses. The RT patterns revealed a short-long effect: Shorter RTs were produced before the short duration than before the longer, provided that the duration was not precued. This short-long effect occurred whatever type of response and effector were involved. Two conclusions were reached. First, response duration was included in the motor program elaborated before execution, whatever the biomechanical features of the response; and, second, the program for the short duration was activated on all trials and was used as a basis for programming longer durations when needed. These conclusions were tested in Experiment 2 (priming; N = 12), in which a small proportion of invalid trials concerning duration was provided. Thus, the duration required by the RS differed from that primed by the WS. Two durations (.7 or 2.5 s) and 2 effectors (the index or the middle finger) were involved. In the invalid trials, the responses of short and long durations did not yield any RT differences, thus confirming the particular status of the short duration. This suggests that deprogramming operations (which lengthen the RT) are needed after a RS to produce short response durations but not after a RS to produce long response durations in the invalid trials.     

A gentzen system for conditional logic

Conditional logic is the deductive system , where is the set of propositional connectives {, ,} and is the structural finitary consequence relation on the absolutely free algebra that preserves degrees of truth over the structure of truth values C, . HereC is the non-commutative regular extension of the 2-element Boolean algebra to 3 truth values {t, u, f}, andf<u<t. In this paper we give a Gentzen type axiomatization for conditional logic.Presented byJan Zygmunt     

Macrosocial determinants of social integration: Social class and area effect

Theory and research on social support have paid little attention to the existence of important macrosocial variables determining level and content of social relationships. This study examines variations in social integration as a function of social class and residential area characteristics. Results for 234 subjects living in high and low risk neighbourhoods indicated that differences between higher and lower social class groups follow different patterns in different residential areas. Also, same social class position appeared to have different significance as a function of residential area characteristics. The levels of three social integration measures—community integration and satisfaction, community association and participation, and contribution in community organizations—were significantly higher for lower class in low risk neighbourhoods than in high risk ones. However, significant differences were found in only one measure for higher social class groups, with higher levels of community association and participation in high risk neighbourhoods than in low risk ones. The discussion examines a ‘social impoverishment’ hypothesis for high risk environments, and proposes possible protective factors for higher status residents. Relations between formal and informal sources of support, and implications for social intervention strategies are also considered.
