The fruits of irony: gaining insight into how we make meaning of the world

Many philosophers of education emphasise the impossibility to really ‘solve’ philosophical—and with that, educational—problems these days. Philosophers have been trying to give philosophy a new, constructive turn in the face of this insolvability. This paper focuses on irony-based approaches that try to exploit the very uncertainty of philosophical issues to further philosophical understanding. We will first briefly discuss a few highlights of historical uses of irony as a philosophical tool. Then we concentrate on two different interpretations of irony, formulated by Bransen and Rorty, that aim at gaining insight into how we make meaning of the world, while at the same time recognising that such an understanding would be impossible. After discussing some problematic aspects of these interpretations a third interpretation of irony is developed, based on a third view of the nature of meaning-making. Following these three interpretations, we will discuss their philosophical merits and the different kinds of insight they can produce for philosophy of education.     

The effect of age of acquisition in visual word processing: further evidence for the semantic hypothesis

The authors investigated whether the meaning of visually presented words is activated faster for early-acquired words than for late-acquired words. They addressed the issue using the semantic Simon paradigm. In this paradigm, participants are instructed to decide whether a stimulus word is printed in uppercase or lowercase letters. However, they have to respond with a verbal label ("living" or "nonliving") that is either congruent with the meaning of the word (e.g., saying "living" to the stimulus DOG) or incongruent (e.g., saying "nonliving" to the stimulus dog). Results showed a significant congruency effect that was stronger for early-acquired words than for late-acquired words. The authors conclude that the age of acquisition is an important variable in the activation of the meaning of visually presented words.     

Prevalence and construct validity of Personality Disorder Not Otherwise Specified (PDNOS)

Personality Disorder Not Otherwise Specified (PDNOS) is one of the most frequently used Axis II diagnoses, yet explicit guidelines for its assessment are lacking. To investigate the prevalence and construct validity of various definitions of PDNOS, 1760 psychotherapy referrals were diagnosed using the Structured Interview for DSM-IV Personality Disorders (SIDP-IV). Construct validity parameters included severity of psychiatric complaints, personality symptoms, and functional impairment. Results show that PDNOS is highly prevalent in this sample (21.6% or 70.8%, depending on whether co-occurrence with formal PD is allowed). Patients with both formal PD and PDNOS have more severe problems than those with formal PD only. In terms of severity, PDNOS takes an intermediate position between formal and no PD. For mixed PD, a cut-off of 5 criteria would yield a large (12.0%) additional PD group with a similar level of functional impairment as compared to mixed PD with a cut-off of either 10 or 15 criteria. In conclusion, the high prevalence of PDNOS warrants proportional attention in science and practice. If PDNOS is retained in DSM-V, it is recommendable to develop explicit guidelines for its assessment.     

Response Inhibition and Measures of Psychopathology: A Dimensional Analysis

On the basis of Quay's (1988a, 1988b, 1993, 1997) model in which the Behavioral Inhibition System (BIS) and the Behavioral Activation System (BAS) are linked to various forms of child psychopathology, predictions were made regarding the relation between inhibitory control and two dimensions of psychopathology: externalizing and internalizing behavior. Inhibitory control was measured using two versions of Logan and Cowan's stop signal paradigm (1984; Logan, Cowan, & Davis, 1984; Osman, Kornblum, & Meyer, 1986, 1990). The primary outcome measure for the stop tasks was stop signal reaction time (SSRT) which measures the latency of the inhibition process. A positive relationship was predicted for externalizing behavior, whereas a negative relationship was predicted for internalizing behavior. A total of 42 non-clinical elementary school children, in the age range of 6 to 12 years, participated in the study. Externalizing behavior was positively related to response inhibition. Symptoms of ADHD seem to be better at predicting inhibitory functioning than symptoms of aggressive behavior disorders. Some support was found for a negative relation between internalizing behavior and inhibitory control. These findings support Quay's model and the discriminant validity of inhibitory control with regard to externalizing and internalizing behavior.     

A meta-analysis of the prevalence and usage of the personality disorder not otherwise specified (PDNOS) diagnosis

The primary aim of the current study was to determine the prevalence and usage of the diagnosis of personality disorder not otherwise specified (PDNOS). As a secondary objective, this study explores the impact of assessment method and definition of PDNOS on observed prevalence. A meta-analysis is reported of 51 studies reporting separate rates for the overall prevalence of specific personality disorders and PDNOS. The best estimate of the absolute prevalence of PDNOS in patient samples is in the range of 8 to 13% and the best estimate of the relative prevalence of PDNOS (i.e., prevalence of PDNOS divided over the overall Axis II prevalence excluding PDNOS) is in the range of 21-49%. In structured interview studies PDNOS is the third most frequently used personality disorder diagnosis, whereas in nonstructured interview studies, PDNOS is often the single most frequently used diagnosis. PDE/IPDE yielded higher PDNOS prevalences than either the SCID or SIDP. Only slightly more than half of the studies provided an operational definition of PDNOS, and the most frequently occurring definition is "mixed" personality disorder. PDNOS would perhaps be the most frequently used diagnosis if it was used in a manner consistent with its definition in DSM-IV. The clinical relevance of future classification, assessment, and research could substantially benefit from validated, explicit, and uniform guidelines for the assessment of PDNOS.     

Prioritizing new elements with a brief preview period: Evidence against visual marking

Watson and Humphreys (1997) have proposed that the ability to prioritize new elements over old elements involves a time-consuming process (of at least 400 msec) of active inhibition of the locations of the old elements, which they referred to asvisual marking. Recently, Donk and Theeuwes (2001) have suggested that prioritized selection of new over old elements is an instantaneous process related to the luminance change accompanying the appearance of the new elements. The aim of the present study was to test these two alternatives by investigating whether prioritized selection of new over old elements could be achieved with a very short preview of the old elements (50 msec). The results indicated that participants were able to prioritize selection of new over old elements when the new elements were presented with luminance onset whereas the old elements were not. New elements could not be prioritized if both the old and the new elements appeared with luminance onset. The results indicated that prioritization of new elements is based on an instantaneous process, rather than on a time-consuming process.     

Taxonomic implications of three prospective studies on the course and outcome of personality disorders

The Children in the Community (CIC) Study (Cohen, Crawford, Johnson, & Kasen, this issue), the McLean Study of Adult Development (MSAD; Zanarini, Frankenburg, Hennen, Reich, & Silk, this issue), and the Collaborative Longitudinal Personality Disorders Study (CLPS; Skodol et al., this issue) are three large prospective studies on the course and outcome of psychiatric disorders, borderline personality disorder, and personality disorders, respectively. These studies, involving approximately 2,000 subjects, have yielded an enormous amount of scientifically and clinically relevant information. In this commentary, I primarily aim to discuss the implications for future revisions to the DSM classification of personality disorders.     

Effects of hypothesis and assigned task on question selection strategies

Semin and Strack (1980) demonstrated that the findings obtained by Snyder and Swann (1978) with respect to an hypothesis-confirming strategy in social interaction were due to the assigned task, and not to a person's hypothesis. In our first experiment we replicated Semin and Strack's results. In a second experiment, employing a more effective manipulation of the subject's hypothesis, support was obtained for an effect of the hypothesis factor. It was concluded that both an assigned task effect and an hypothesis effect can be demonstrated in the laboratory and probably exist in reality.     

The burden of disease in personality disorders: diagnosis-specific quality of life

A generic quality of life measure was used to investigate the burden of disease in a large sample of patients with personality disorders. The 1,708 subjects included in this study were recruited from six different mental health care institutes in the Netherlands. The burden of disease was measured using the EuroQol EQ-5D. Personality disorders were diagnosed using the Structured Interview for DSM-IV Personality (SIDP-IV). The mean EQ-5D index value was 0.56. Primarily the total number of personality disorder diagnoses rather than the specific type determined the quality of life. Notably borderline personality disorder was not associated with the highest burden. The findings indicate that patients with personality disorders experience a high burden of disease, comparable to that of severe somatic illnesses. The results call into question the primary focus in literature on borderline personality disorder. The current study yields a strong argument in favor of reimbursing (effective) treatments for this patient population.
