Divergence between community psychologists in academic and nonacademic settings: A closer look at the implications

The ecological principle of interdependence has been a guiding theme in our research and conceptualization. For the development of community psychology, academic and applied interest and networks must be integrated in ways which value the views and resources of both groups. This is the focus of Kelly's (1984) remarks. The dynamic interplay of ideas, data, and practices is likely to facilitate the collaboration between researchers and setting inhabitants which Trickett (1984) describes as the distinctive quality of community psychology. Common pathways of information exchange, joint responsibility for training future members of the field, and mutually enhancing role relationships are needed. Current channels of communication provide little ease of access or incentives for participation by psychologists in nonacademic settings. It thus becomes the reponsibility of all concerned community psychologists to use their organizational skills to redress this harmful imbalance (Kelly, 1984). For this to occur, however, we must take the initial steps of frankly recognizing differences in our folkways and organizational constraints, while also emphasizing our common values and assets. The largest threat to the field is external constraints from university and clinical service settings on the work that represents community psychology (Elias et al., 1984). If we are dividedor uninformed in the face of these environmental presses, we will never create the adaptive niche that community psychology needs to survive.     

Detection of change in shape: an advantage for concavities

Shape representation was studied using a change detection task. Observers viewed two individual shapes in succession, either identical or one a slightly altered version of the other, and reported whether they detected a change. We found a dramatic advantage for concave compared to convex changes of equal magnitude. Observers were more accurate when a concavity along the contour was introduced, or removed, compared to a convexity. This result sheds light on the underlying representation of visual shape, and in particular the central role played by part-boundaries. Moreover, this finding shows how change detection methodology can serve as a useful tool in studying the specific form of visual representations.     

Past tense formation and comprehension of passive sentences in Parkinson's disease: evidence from Greek

The present study investigates the production of regular and irregular verbs in the past tense and the comprehension of passive sentences by Greek-speaking PD patients, and compares their behavior to that of normal speakers. Although the two groups manifest large scale differences at all the above constructions, the behavior of PDs is not different at regular vs. irregular past tense formation neither did we obtain strong evidence that they do not comprehend passives, most importantly, they certainly do not perform at chance. On the basis of the above, we conclude that there are no indications for a clearly linguistic deficit of the PD group, hence, their difference with the control group should be attributed to other factors, such as the computational demands of the tasks.     

Hemispheric asymmetries for gap detection depend on noise type

Studies of temporal processing asymmetries in the auditory modality have not produced consistent results. Some investigators have found a left hemisphere advantage, but others have failed to replicate this result. The present experiment investigated the possibility that differing properties of the noise employed between these experiments could be responsible for the conflicting results. Short bursts (300 ms) of white or brown noise were delivered monaurally to 42 participants. Half of the stimuli contained 3-5 ms gaps of silence. A right ear (left hemisphere) advantage in accuracy was observed in the white noise condition, but there was no such difference in the brown noise condition. This result demonstrates that the different acoustic properties of the stimuli between experiments can account for some of the discrepancies in their findings, and supports the position that the left hemisphere is superior at processing rapid temporal changes.     

Counsellor role perceptions and preferences of Zimbabwe teachers of a Shona cultural background

Thurstone's Case V paired comparisons procedure was used to investigate the perceived role status and preferences of counsellor for a sample of Zimbabwe teachers of a Shona cultural backgroud (n = 312) in relation to type of presenting problem (personal; educational; employment) and as the teachers varied by gender, age, level of formal educationa and marital status. Counsellor expertise contrasted those of modern status (psychologist; church pastor; work supervisor) and traditional status (family members; traditional healer; friend). The teachers seemed to have an undifferentiated perception of counselling needs as measured by preferences for helper. Age jand level of formal education were significantly related to counsellor prefernces, with the older and less schooled teachers tending to endorse counsellors of a traditional status. The results are considered with respect to the provision as well as public image of counselling services in an African culture.     

Paraconsistent logic and model theory

The object of this paper is to show how one is able to construct a paraconsistent theory of models that reflects much of the classical one. In other words the aim is to demonstrate that there is a very smooth and natural transition from the model theory of classical logic to that of certain categories of paraconsistent logic. To this end we take an extension of da Costa'sC ₁ ⁼ (obtained by adding the axiom A A) and prove for it results which correspond to many major classical model theories, taken from Shoenfield [5]. In particular we prove counterparts of the theorems of o-Tarski and Chang-o-Suszko, Craig-Robinson and the Beth definability theorem.     

A consciousness-based quantum objective collapse model

Ever since the early days of quantum mechanics it has been suggested that consciousness could be linked to the collapse of the wave function. However, no detailed account of such an interplay is usually provided. In this paper we present an objective collapse model (a variation of the Continuous Spontaneous Location model) where the collapse operator depends on integrated information, which has been argued to measure consciousness. By doing so, we construct an empirically adequate scheme in which superpositions of conscious states are dynamically suppressed. Unlike other proposals in which “consciousness causes the collapse of the wave function,” our model is fully consistent with a materialistic view of the world and does not require the postulation of entities suspicious of laying outside of the quantum realm.

     

Predicting outcome of chronic pain treatment via a modified self-efficacy scale

This study utilized a modified self-efficacy scale and examined the relationship of perceived self-efficacy to treatment outcome in a chronic, intractable, benign pain population (N = 62). In two separate studies a self-efficacy scale was given to inpatients in a combined cognitive-behavioral and medical treatment program. The scale categories consisted of (1) walking distance, (2) lifting ability, (3) pain coping, (4) working ability, and (5) social and recreational engagement. Self-efficacy beliefs were found to be associated with the level of functioning of these patients and their response to treatment. Patients with higher self-efficacy scores following treatment rated themselves as more improved and demonstrated better overall functioning with greater reductions in chronic illness behavior at followup. These observations support the merits of self-efficacy measures as predictors of treatment outcome in chronic pain patients.
