A review of the biological bases of ADHD: what have we learned from imaging studies?

Attention Deficit Hyperactivity Disorder (ADHD) is a common and impairing neuropsychiatric disorder with onset at preschool age. Although a significant amount of progress has been made investigating the neurobiology of this disorder, its precise etiology still remains unclear. Converging evidence from studies of the neuropharmacology, genetics, neuropsychology, and neuroimaging of ADHD imply the involvement of fronto-striatal circuitry in ADHD. However, while it does appear that poor inhibitory control and the deficits in fronto-striatal circuitry associated with it are central, there is evidence to suggest that more posterior cerebral areas are also implicated in this disorder. Anatomical studies suggest widespread reductions in volume throughout the cerebrum and cerebellum, while functional imaging studies suggest that affected individuals activate more diffuse areas than controls during the performance of cognitive tasks. The future impact of new MR imaging methodologies on the field is discussed.     

Do we know what we've learned from listening to the news?

This study investigates the relationship between knowledge acquisition and an awareness of that knowledge within the context of listening to the news, Subjects listened to a recording of a radio news program consisting of regular news items as well as editorials, manipulated to be of high or low personal relevance. They then completed a surprise memory test and rated their confidence in their answers. In contrast to many studies, the results indicated a strong positive confidence-accuracy relationship. Confidence ratings were generally a better predictor of an individual's performance than were predictions based on item difficulty. Whereas subjects reported strong and accurate feelings of knowing, they apparently lacked complementary feelings ofnot knowing. The implications of these findings and others are discussed.     

Text processing and feedback: what have we learned?

In studies on the effects of feedback on text comprehension, it was determined that text content interacts differentially with the feedback provided. Specifically, the types of memorial representations sought must be considered in terms of type of text, feedback timing, frequency, and modality.     

Imaging the developing brain: what have we learned about cognitive development?

The human brain undergoes significant changes in both its structural architecture and functional organization across the life span. Advances in neuroimaging techniques over the past decade have allowed us to track these changes safely in the human in vivo. We review the imaging literature on the neurobiology of cognitive development, focusing specifically on cognitive task-dependent changes observed in brain physiology and anatomy across childhood and adolescence. The findings suggest that cortical function becomes fine-tuned with development. Brain regions associated with more basic functions such as sensory and motor processes mature first, followed by association areas involved in top-down control of behavior.     

Preventing adolescent smoking: what have we learned about treatment construct validity?

In recent years, numerous programs introduced to prevent adolescent smoking have demonstrated some success. This paper reviews the treatment construct validity of such programs; that is, we seek to determine how and why programs reduce adolescent smoking. The review leads to the conclusion that little is presently known about the construct validity of successful programs, a problem that results primarily from the neglect of process assessment and analyses. The advantages and disadvantages of several future research approaches are discussed, including: (a) utilization of process measures within large scale treatment/no-treatment designs, (b) small-scale studies to test the effects of prevention components on process measures (e.g., attitudes, intentions to smoke), and (c) combinations of these two approaches.     

Research on calling: What have we learned and where are we going?

Work as a calling is an emerging concept for scholars across a variety of psychological disciplines. In the current paper, the extant literature on calling is reviewed, showcasing its salience among college student and adult populations and highlighting consistent links between perceiving a calling and heightened levels of career maturity, career commitment, work meaning, job satisfaction, life meaning, and life satisfaction. These links appear most robust when individuals are actually living out their calling at work. Seven suggestions are proposed for future researchers to better understand what it means to have and live a calling: developing a stronger conceptual understanding, collecting more longitudinal data, studying more diverse cultural groups, focusing on behavioral outcomes, examining the dark side of a calling, building theory, and testing interventions. It is hoped that the promising research base and vast areas of potential growth will continue to make the study of calling attractive to scholars across psychological disciplines.

Intraindividual models of employee well-being: What have we learned and where do we go from here?

As societal concern shifts from financial survival towards quality of life issues, both in and outside of the workplace, scholarly interest in employee well-being too has risen greatly in recent years. This greater attention to the antecedents and outcomes of employee well-being, such as job satisfaction, work engagement, and job burnout amongst others, is reflected in the proliferation of theories, constructs, and studies seeking to describe and explain why employees flourish or become exhausted at work, and the effect of employee well-being on individual behaviours and the organization at large. In this article, we provide a selective review of the current state of research in employee well-being, as well as key theories that have been employed in its study, with the aim of providing a critical assessment of the current state of employee well-being research as well as suggest future directions for the field. In particular, we discuss how research adopting intraindividual perspectives in the study of employee well-being can not only add value to our understanding of well-being but also complement the findings from between-individual studies, and offer suggestions for the development of a comprehensive theoretical model that integrates the two perspectives.     

A decade of infant neuroimaging research: What have we learned and where are we going?

The past decade has seen the emergence of neuroimaging studies of infant populations. Incorporating imaging has resulted in invaluable insights about neurodevelopment at the start of life. However, little has been enquired of the experimental specifications and study characteristics of typical findings. This review systematically screened empirical studies that used electroencephalography (EEG), magnetoencephalography (MEG), functional near-infrared spectroscopy (fNIRS), and functional magnetic resonance imaging (fMRI) on infants (max. age of 24 months). From more than 21,000 publications, a total of 710 records were included for analyses. With the exception of EEG studies, infant studies with MEG, fNIRS, and fMRI were most often conducted around birth and at 12 months. The vast majority of infant studies came from North America, with very few studies conducted in Africa, certain parts of South America, and Southeast Asia. Finally, longitudinal neuroimaging studies were inclined to adopt EEG, followed by fMRI, fNIRS, and MEG. These results show that there is compelling need for studies with larger sample sizes, studies investigating a broader range of infant developmental periods, and studies from under- and less-developed regions in the world. Addressing these shortcomings in the future will provide a more representative and accurate understanding of neurodevelopment in infancy.     

Psychoanalytic interpretation of the Rorschach: do we have better hieroglyphics?

Schafer (1954) advanced the "Psychoanalytic Interpretation in Rorschach Testing" and asserted that thoughtful interpretation involved more than translating hieroglyphics or scores. In this book, he presented his thesis by describing four defensive styles (repression, denial, projective, and obsessive-compulsive) at various levels of severity of psychopathology. To investigate whether the Structural Summary data from Exner's (1986) Comprehensive System, with its improved reliability and validity and additional scores, allow one to make similar distinctions among the types of defense and severity of disturbance, we rescored the Schafer records. The results of this conservative test of Exner's system suggest that (a) the Comprehensive System reliably distinguishes the repressive style from the other styles, and (b) scores alone may provide adequate measures of severity of disturbance even with form quality excluded. We concluded that Rorschach scores must be understood as complex products of multiple psychological operations and may correspond to different subjective experiences in various contexts.     

What can we learn about physical laws from the fact that we have memories only of the past?

Not much. I demonstrate this by constructing a model of a memory system governed by deterministic, time reversible laws only, thereby showing that the mere fact of our having memories solely of the past does not necessitate an indeterministic, time asymmetric or stochastic physics, essentially thermodynamic processes or a primitive notion of time asymmetric causation.

Return to Sepharad: Is it possible to heal an ancient wound? A reflection on the construction of large-group identity

Abstract

Spanish parliament recently issued a new law offering Spanish nationality to Sephardic Jews who so desired and could demonstrate a basic knowledge of the Spanish language and culture. This law attempted to redress a five-centuries-old injustice and was expected to unleash both criticism and praise. Surprisingly, reactions in the public or the press were minimal or absent. Reasons for this are explored through a qualitative study with focus groups, which showed ideas that can be grouped into four main categories: ignorance, justice, distrust, and fear. It is hypothesized that the predominantly silent response to the new law might be due to the fact that it touches on an extremely sensible issue: the historically fragmented Spanish identity. A position of negation is constructed, to avoid deep anxieties related to the fragile core of a collective identity built from many “others” forced to the refuge of an introspection that protects them from the conviction of not fulfiling the ideal identity status, known by all but reached by none. All those “others” have mixed their bloods with the Old Christians along the centuries, possibly transmitting a profound insecurity about their personal and collective identity that might contribute to understanding current social reactions.     

When educational supervision meets clinical supervision: what can we learn from the discrepancies?

The authors question the taken-for-granted notion of supervision. Their concerns arose out of an attempt to introduce 'clinical' supervision into academia as a way of addressing an increasing number of the ethical issues which confront lecturers. They recognise that knowledge can impact adversely on students and that lecturers at times find themselves compromised. They settled on supervision as an organisational space in the domain of power in which to address the distress they observed. However, through their different experiences of supervision, they soon found themselves talking past each other. When clinical supervision meets educational supervision, several anomalies are brought to the fore. The authors draw on Foucault's notion of discourse, and of knowledge as power, in order to foreground these and conclude by cautioning against an uncritical acceptance of supervision as an ethical practice. They believe there is a benefit in bringing together the two discourses of clinical and educational supervision for further discussion.
