Application of Attachment Theory to Equine-Facilitated Psychotherapy

Equine-facilitated psychotherapy (EFP) is a form of animal-assisted therapy used to treat human psychological problems that employs horses in and around the natural surroundings of the stables. Despite the increasing number of professionals and organizations that offer this innovative therapy, EFP lacks a firm theoretical and research base. This paper aims to reveal how attachment theory can inform and enrich theory and practice of EFP. It explores the fit between central features of EFP and several of the primary concepts of attachment-based psychotherapy, such as: secure base and haven of safety through the provision of a holding environment, affect mirroring, mentalizing and reflective functioning, and non-verbal communication and body experience. This work is composed of definitions of these concepts, their application to human–horse context and EFP, and interpretation in light of potential therapeutic (transformative) processes.     

Prosodic knowledge affects the recognition of newly acquired words

An eye-tracking study examined the involvement of prosodic knowledge--specifically, the knowledge that monosyllabic words tend to have longer durations than the first syllables of polysyllabic words--in the recognition of newly learned words. Participants learned new spoken words (by associating them to novel shapes): bisyllables and onset-embedded monosyllabic competitors (e.g., baptoe and bap). In the learning phase, the duration of the ambiguous sequence (e.g., bap) was held constant. In the test phase, its duration was longer than, shorter than, or equal to its learning-phase duration. Listeners' fixations indicated that short syllables tended to be interpreted as the first syllables of the bisyllables, whereas long syllables generated more monosyllabic-word interpretations. Recognition of newly acquired words is influenced by prior prosodic knowledge and is therefore not determined solely on the basis of stored episodes of those words.     

The modulation of lexical competition by segment duration

In an eye-tracking study, we examined how fine-grained phonetic detail, such as segment duration, influences the lexical competition process during spoken word recognition. Dutch listeners’ eye movements to pictures of four objects were monitored as they heard sentences in which a stop-initial target word (e.g.,pijp “pipe”) was preceded by an [s]. The participants made more fixations to pictures of cluster-initial words (e.g.,spijker “nail”) when they heard a long [s] (mean duration, 103 msec) than when they heard a short [s] (mean duration, 73 msec). Conversely, the participants made more fixations to pictures of the stop-initial words when they heard a short [s] than when they heard a long [s]. Lexical competition between stop- and cluster-initial words, therefore, is modulated by segment duration differences of only 30 msec.     

Do patients with OCD and pathological gambling have similar dysfunctional cognitions?

The obsessive-compulsive spectrum disorder (OCSD) theory postulates that a wide range of disorders is closely related to OCD. Current cognitive models ascertain that certain beliefs leading to misinterpretation of the significance of intrusions are important in the etiology and maintenance of OCD. This study examined whether pathological gambling, a disorder belonging to the OC spectrum, is characterized by similar dysfunctional cognitions as OCD. Dysfunctional beliefs of OCD patients were compared to those of patients with pathological gambling, panic disorder and normal controls. These beliefs were measured by the Obsessive-compulsive Beliefs Questionnaire-87 (OBQ-87), which was developed by a group of leading OCD researchers [Behav. Res. Ther. 35 (1997) 667]. It was hypothesized that according to the OCSD theory, pathological gamblers would exhibit similar cognitions to OCD patients, as well as increased levels of OCD symptoms. Analysis showed that OCD patients exhibited higher OBQ-87 scores than both panic patients and normal controls, but equal to pathological gambling patients. Pathological gamblers exhibited, however, no increase in OCD symptoms. These mixed results do not seem to support the OC spectrum theory for pathological gambling, moreover being contradictory to contemporary cognitive OCD models.     

Healthy Children As Subjects in Pharmaceutical Research

Recruitment of healthy children for drugresearch has emerged due in part to several newAmerican laws and policies that have led to asurge in pharmaceutical research involvingchildren-subjects. In this paper, I review theethical and scientific issues and the argumentsin favor and against this new practice.     

Recognition models of alphanumeric characters

Several methods to study the recognition and similarity of alphanumeric characters are briefly discussed and evaluated. In particular, the application of the choice-model (Luce, 1959, 1963) to recognition of letters is criticized. A feature analytic model for recognition of alphanumeric characters based on Tversky’s (1977) features of similarity is proposed and tested. It is argued that the proposed model: (a) is parsimonious in that it utilizes a relatively small number of parameters, (b) is psychologically more meaningful compared with other approaches in that it is attempting to study underlying processes rather than just reveal a similarity structure, (c) yields predictions that have a high level of fit with the observed data. Possible implications from the use of the model for future research are briefly discussed.     

The authority of pleasure

The aim of the paper is to reassess the prospects of a widely neglected affective conception of the aesthetic evaluation and appreciation of art. On the proposed picture, the aesthetic evaluation and appreciation of art are non‐contingently constituted by a particular kind of pleasure. Artworks that are valuable qua artworks merit, deserve, and call for a certain pleasure, the same pleasure that reveals (or at least purports to reveal) them to be valuable in the way that they are, and constitutes their aesthetic evaluation and appreciation. This is why and how art is non‐contingently related to pleasure. Call this, the Affective View. While I don't advance conclusive arguments for the affective view in this paper, I aim to reassess its prospects by (1) undermining central objections against it, (2) dissociating it from hedonism about the value of artworks (the view that this value is grounded in, and explained by, its possessors’ power to please), and (3) introducing some observations on the practice of art in support of it. Given that the objections I discuss miss their target, and given the observations in support of it, I conclude that the affective view is worth serious reconsideration.     

On Liking Aesthetic Value

According to tradition, aesthetic value is non-contingently connected to a certain feeling of liking or pleasure. Is that true? Two answers are on offer in the field of aesthetics today: 1. The Hedonist answers: Yes, aesthetic value is non-contingently connected to pleasure insofar as this value is constituted and explained by the power of its possessors to please (under standard conditions). 2. The Non-Affectivist answers: No. At best, pleasure is contingently related to aesthetic value. The aim of this paper is to point to a blind spot in the dialectic between these two standard positions by defending a third neglected answer to the question above, the answer of the Value-Meriting-Pleasure [VMP] advocate. According to this answer, a certain kind of (cognitive and responsive) pleasure is connected to aesthetic value non-contingently, but also non-hedonically. VMP is the view that objects of aesthetic value are non-contingently related to pleasure insofar as they merit a certain kind of pleasure. But, pace the hedonist, those objects are valuable (those that are to be engaged with etc.) neither on account of their capacity to give pleasure nor on account of the hedonic value of the attitude they merit.     

Einstein,his theories,and his aesthetic considerations

This article deals with the question whether aesthetic considerations affected Einstein in formulating both his theories of relativity. The opinions of philosophers and historians alike are divided on this matter. Thus, Gerald Holton supports the view that Einstein employed aesthetic considerations in formulating his theory of special relativity whereas Jim Shelton opposes it, one of his reasons being that Einstein did not mention such considerations. The other theory, namely, that of general relativity, is discussed by John D. Norton. He asserts that the successful completion of this theory was due to Einstein's adherence to mathematical simplicity resulting from experience, as Einstein himself stated, and not from an aesthetic drive, to which he did not refer. The present work attempts to overcome this deficiency indirectly by investigating Einstein's aesthetic awareness and its consequences for his work. It is found that this awareness was imbedded in his perception of nature and is linked to the criteria (such as simplicity) that guided him in formulating his theories. The conclusion thus reached is that aesthetic considerations did play a role in Einstein's endeavour, contrary to the assertions of Shelton and Norton.     

On the relationship between sources of within- and between-group differences and measurement invariance in the common factor model

Investigating sources of within- and between-group differences and measurement invariance (MI) across groups is fundamental to any meaningful group comparison based on observed test scores. It is shown that by placing certain restrictions on the multigroup confirmatory factor model, it is possible to investigate the hypothesis that within- and between-group differences are due to the same factors. Moreover, the modeling approach clarifies that absence of measurement bias implies common sources of within- and between-group variation. It is shown how the influence of background variables can be incorporated in the model. The advantages of the modeling approach as compared with other commonly used methods for group comparisons is discussed and illustrated by means of an analysis of empirical data.
