Exploring and integrating discrete and dimensional approaches while inducing negative emotional states

Selecting visual stimuli for inducing specific emotional states is very challenging, since the choice relies on specific conceptualization of emotions. In this work, we present a set of 55 stimuli, realized integrating discrete and dimensional theories of emotions, and specifically selected to investigate anger, fear, and disgust reactions in non-clinical and clinical contexts. Our set of stimuli presents several aspects of novelty since (1) a large and heterogeneous sample of subjects from the general population was involved in the labelling task, and (2) bivariate and multivariate statistical techniques were applied to integrate emotion models. The proposed set of stimuli could be useful for researchers and other professionals in the affective sciences to address negative emotion recognition issues within a broader perspective both in general population and in psychiatric samples. The obtained comprehensive characterization of the stimuli allowed us to confirm the sexual dimorphism in emotional processing.     

Effects of a REBT Based Training on Children and Teachers in Primary School

Rational Emotive Education (REE) is a psychological educational program offering a preventative psycho-educational curriculum to children in order to teach them emotional literacy skills. REE helps children by teaching them to challenge irrational thinking, to minimize their reactions to disappointment and frustrations, to cope more effectively with problems, and to more fully accept themselves. The efficacy of REE training for children and teachers was examined in a sample of 211 third grade students from nine different classes and 26 teachers. Each class was randomly assigned to one of three different groups, two experimental groups and a control group, each receiving different training. First objective of our study was to evaluate the efficacy of a REE training based on storytelling in changing children’s irrational beliefs. Second objective of our study was to observe the efficacy of a teachers’ training similar to that applied in REBT-focused school consultation groups in enhancing their self-efficacy. Results show an improved tendency in children to think rationally and an enhanced perception of self-efficacy in teachers for those groups that underwent the training compared to the control group. Our results suggest that REBT based trainings for children and teachers should be integrated into the classroom curriculum in order to prevent mental health problems and encourage positive social and emotional well-being.     

So hard to say goodbye? An investigation into the symbolic aspects of unintended disposition practices

Even though disposition is present in the consumer behavior research agenda, most of the studies focus mainly on intentional movements of products leaving the home. The present article describes a less conscious and co‐incidental journey of products into a liminal zone between use and disposal inside homes. A qualitative field study, based on the itinerary method, was undertaken with a group of 26 affluent women in Brazil. The findings show that consumers maintain purgatories – “forgotten” repositories of products no longer in use – as an in‐home disposition practice. The aspects and functioning of purgatory are also detailed, through a typology of purgatories and a discussion of specific strategies to deal with cluttering as a consequence of product accumulation inside homes. Finally, purgatories emerge as a contemporary consumer solution to deal not with individual products but with product collectivities' disposition. Copyright © 2016 John Wiley & Sons, Ltd.     

From pregnancy to motherhood: The structure of representative and narrative change

The aim of this work was to identify ways of objectifying the course of mothers' represen tations of their babies and themselves as mothers during pregnancy and the postpartum period. A sample of 51 women attending a Family Guidance Clinic for psychoprophylaxis courses was studied using semistruc tured interviews that were administered in the 7th month of pregnancy and on the 5th day and in the 4th month postpartum. This paper describes a method for classifiying themes identified in the mothers' representations of the baby and of the self-as-mother as wish-organized, defense-organized, fear-organized, or disorganized. This classification derives from the presumed clinical function of the narrative themes in the mothers' representational world. Themes about the baby and about the self-as-mother were primarily fear-organized at the 7th month of pregnancy. On the 5th day postpartum, there was no prevailing thematic organization. At 4 months postpartum, representations of the baby were primarily fear-organized and almost never disorganized. We speculate that themes about the baby and the self-as-mother that are disorganized may have negative prognostic significance.     

Regulation and Mechanism of L-Type Calcium Channel Activation via V1a Vasopressin Receptor Activation in Cultured Cortical Neurons

We have sought to elucidate the biochemical mechanisms that underlie the memory enhancing properties of the neural peptide vasopressin. Toward that goal we have investigated vasopressin induction of calcium signaling cascades, long held to be involved in long-term memory function, in neurons derived from the cerebral cortex, a brain region associated with long-term memory. Our previous studies demonstrated that in cultured cortical neurons, V1a vasopressin receptor (V1aR) activation resulted in a sustained rise in intracellular calcium concentration that was dependent on calcium influx (Son & Brinton, 1998). To investigate the mechanism of V1aR-induced calcium influx, we investigated V1aR activation of the calcium channel subtype(s) in cortical neurons cultured from Sprague-Dawley rat embryonic day 18 fetuses. The results of these analyses demonstrated that the L-type calcium channel blocker nifedipine blocked 250 nM V1 vasopressin receptor agonist (V1 agonist)-induced calcium influx. Intracellular calcium imaging analyses using fura-2AM demonstrated that blockade of L-type calcium channels prevented the 250 nM V1 agonist-induced rise in intracellular calcium concentration. These results indicate that the influx of extracellular calcium via L-type calcium channels is an essential step in the initiation of the V1 agonist-induced rise in intracellular calcium concentration. To determine the mechanism of V1aR activation of L-type calcium channels, regulatory components of the phosphatidylinositol signaling pathway were investigated. The results of these analyses demonstrated that V1 agonist-induced calcium influx was blocked by both a phospholipase C inhibitor (U-73122) and a protein kinase C inhibitor (bisindolylmaleimide I). Further analysis of V1aR activation of protein kinase C (PKC) demonstrated that V1 agonist induced PKC activity within 1 min of exposure in cultured cortical neurons. These data indicate that in cultured cortical neurons, V1aR activation regulates the influx of extracellular calcium via L-type calcium channel activation through a protein kinase-C-dependent mechanism. The results of these studies provide biochemical mechanisms by which vasopressin could enhance memory function. Those mechanisms include a complex cascade that is initiated by activation of the phosphatidylinositol pathway, activation of protein kinase C, followed by phosphorylation of L-type calcium channels to initiate the influx of extracellular calcium to activate a cascade of calcium-dependent release of intracellular calcium.     

Breakdowns in flexible use of information: Intelligence-related differences in transfer following equivalent learning performance

Groups of retarded and nonretarded children were investigated as they learned three rules underlying problems adapted from the Raven Progressive Matrices Test: rotation, imposition, and subtration. The interest was in evaluating group differences in the ease with which the original set of rules was learned and the flexibility with which these rules were transferred to modified contexts. In the case of either learning or transfer, the metric of performance was the amount of aid, specifically the number of computer-generated graduated hints, needed for each subject to solve the problems. The groups were matched on their entering competence to deal with the rules under scrutiny, and also on mental age. No group differences were obtained as the subjects learned the original set of rules. However, on subsequent occasions when required to make flexible use of those rules, clear group differences emerged; and those differences increased as the similarity of the training and test contexts decreased. The results were seen as consistent with theories that emphasize transfer flexibility as one potential source of individual and comparative differences in intelligence.     

The internal structure of English transitive sentences

A major question in psychology is whether the same mechanisms are required for language learning and processing as for other cognitive tasks. A substantial body of literature has shown that natural categories are organized around a prototype, with other category members resembling the prototype to a greater or lesser amount based on the degree of shared properties. In order to investigate whether the prototype notion could be extended to linguistic phenomena, adult students (N=148) rated 512 sentences on a 7-point scale as to their goodness of fit to the categoryEnglish transitive sentence. Sentences differed in the animacy fo their actors and patients, the noun pairs used as actor/patient exemplars, and the hypothesized prototypicality of their verbs. Each of the identified factors showed the spread in ranking across different exemplars that is typical of other natural categories, but the factors interacted with each in complex ways to determine the overall ranking of the sentence. Not all sentences were equally representative of the categoryEnglish transitive sentence. In general, sentences with animate actors, high-prototypicality verbs, and animate patients were the most prototypical, followed closely by sentences with animate actors high-prototypicality verbs, and inanimate patients. Results were consistent with the suggestion that language and other types of cognitive tasks require the same basic processes and structures.     

Dynamically oriented group therapy with alcoholics: Making it work despite the prevailing bias

A bias exists in the psychiatric community against dynamically oriented group therapy with alcoholics. The basis for this bias lies primarily in negative experiences of practitioners who have attempted to use traditional therapy with alcoholic patients who continued to drink. At Appleton Outpatient Clinic, we have found that dynamically oriented group therapy is a highly suitable treatment modality for alcoholic patients when negative biases of treators can be addressed and when initial preparatory work is done with patients. This preparatory work includes: (a) building a working alliance around abstinence and providing adequate supports to make this possible; (b) explicit contracting that establishes clear treatment goals and consequences should the goals not be met; (c) preparatory short-termgroup experiences.This paper was presented at the 1988 annual meeting of the American Group Psychotherapy Association.     

Stages of manual exploration in haptic object identification

In a yes/no identification task using touch alone, subjects indicated whether an object belonged to a named category. Previously, we found that subjects explored in two stages—first grasping and lifting the object, then executing further exploratory procedures (Lederman & Klatzky, 1990b). We proposed that Stage 1 (grasp/lift) was sufficient to extract coarse information about multiple object properties, whereas Stage 2 was directed toward precise information about particularly diagnostic properties. the current study, subjects were initially constrained to grasping and lifting, after which they could explore further. Accuracy was above chance after Stage 1, confirming our assumption that the grasp/lift combination was broadly useful. Stage 2 increased accuracy and confidence. It primarily elicited exploratory procedures associated with object geometry, but exploration was also influenced by diagnostic object properties.
