A Davidsonian argument against incommensurability

The writings of Kuhn and Feyerabend on incommensurability challenged the idea that science progresses towards the truth. Davidson famously criticized the notion of incommensurability, arguing that it is incoherent. Davidson's argument was in turn criticized by Kuhn and others. This article argues that, although at least some of the objections raised against Davidson's argument are formally correct, they do it very little harm. What remains of the argument once the objections have been taken account of is still quite damaging to the thesis that formerly endorsed scientific theories are incommensurable with those of today's science.     

The experiences of therapists using a new client‐centred psychometric instrument,PSYCHLOPS (Psychological Outcome Profiles)

PSYCHLOPS (‘Psychological Outcome Profiles’) is a newly developed client‐generated psychometric instrument which can be used as an outcome measure. Uniquely, it asks clients to state their own problems, in their own words. As part of its validation, we used it alongside an existing measure, CORE‐OM (‘Clinical Outcomes Routine Evaluation – Outcome Measure’). Based on a qualitative methodology, we report here on the first‐hand experiences of four therapists using both instruments. The key themes that emerged from therapists’ responses were feasibility, validity and usefulness. Both questionnaires were perceived as complementing each other, the qualitative information from PSYCHLOPS balancing the quantitative information from CORE‐OM and that both could contribute to the therapist‐client interaction. The key features of PSYCHLOPS are likely to prove attractive to therapists and should increase acceptance and uptake of outcome measures.     

Psychiatric nurses' experiences with inpatient aggression

Using a survey instrument, the experiences of psychiatric nurses with inpatient aggression were investigated in East London, U.K. On this “Perceptions of Prevalence Of Aggression Scale” (POPAS), annual experiences with 15 types of disruptive and aggressive behavior were rated anonymously. Staff members were also asked to disclose the number of days missed from work due to inpatient violence. On the basis of these POPAS forms, internal consistency of the instrument, mean reported aggression frequencies, and days missed from work due to violence were calculated. Internal consistency of the POPAS appeared to be reasonable. Verbal abuse and threats were experienced by most of the psychiatric nurses during a one‐year period (i.e., by about 80–90 percent of nurses). Sexual harassment or intimidation was also experienced relatively often on an annual basis (68 percent), particularly by female and young staff members. A minority of staff members (i.e., 16 percent) had experienced severe physical violence. Although not prevalent, this type of behavior was most strongly connected with reporting sick. In particular, staff members working with involuntarily admitted patients experienced much (severe) violence during their work. Although the validity of estimates of aggression prevalence with the POPAS instrument needs to be investigated further, such a survey may be helpful in gaining insight rather quickly into the level of day‐to‐day contact with aggressive behavior. Also, since information on verbal, physical, and sexual violence, and on days missed from work, can be provided anonymously, this rather delicate, but essential management information, may be accessed relatively easily with the POPAS.

Use of a multicomponent treatment for food refusal

We examined the use of a multicomponent treatment for food refusal exhibited by a 5-year-old boy who had been diagnosed with mild to moderate mental retardation. Treatment consisted of access to highly preferred tangible items, which were removed contingent on problem behavior or not accepting a bite, and differential reinforcement of alternative behavior. Treatment resulted in an increase in food acceptance to 100% of bite offers and near-zero rates of problem behavior. In addition, the participant's caregivers were successfully trained to implement the treatment.     

The demise of short-term memory revisited: empirical and computational investigations of recency effects

In the single-store model of memory, the enhanced recall for the last items in a free-recall task (i.e., the recency effect) is understood to reflect a general property of memory rather than a separate short-term store. This interpretation is supported by the finding of a long-term recency effect under conditions that eliminate the contribution from the short-term store. In this article, evidence is reviewed showing that recency effects in the short and long terms have different properties, and it is suggested that 2 memory components are needed to account for the recency effects: an episodic contextual system with changing context and an activation-based short-term memory buffer that drives the encoding of item-context associations. A neurocomputational model based on these 2 components is shown to account for previously observed dissociations and to make novel predictions, which are confirmed in a set of experiments.     

The activities of UNESCO in the area of ethics

The member states of the United Nations Educational, Scientific and Cultural Organization (UNESCO) decided in 2002 that ethics is one of the five priority areas of the organization. This article describes three categories of past and current activities in the ethics of science and technology, in particular bioethics. The first category is the global standard setting with the Universal Declaration on Bioethics and Human Rights as the most recently adopted normative instrument. The second category focuses on capacity building in order to enable member states to apply the provisions of the declarations, through, for example, the establishment of national bioethics committees, the introduction of ethics teaching programs, and drafting of legislation and guidelines. The final category of activities is awareness raising through publications, events, and conferences. The challenges and difficulties UNESCO may face in its various activities are highlighted.     

Procedural justice and status: status salience as antecedent of procedural fairness effects

The current article explores status as an antecedent of procedural fairness effects (the findings that perceived procedural fairness affects people's reactions, e.g., their relational judgments). On the basis of the literature, the authors proposed that salience of the general concept of status leads people to be more attentive to procedural fairness information and that, as a consequence, stronger procedural fairness effects should be found. In correspondence with this hypothesis, Experiment 1 showed stronger procedural fairness effects on people's relational treatment evaluations in a status salient condition compared with a control condition. Experiment 2 replicated this effect and, in further correspondence with the hypothesis, showed that status salience led to increased cognitive accessibility of fairness concerns. Implications for the psychology of procedural justice are discussed.
