Learning to Decide with and without Reasoning: How Task Experience Affects Attribute Weighting and Preference Stability

Certain experiments have shown that reasoning may weaken the stability of people's preferences, especially with regard to well‐learned perceptual judgment and decision‐making tasks, while learning has an opposite, consistency‐enhancing effect on preferences. We examined the effects of these factors in a visual multi‐attribute decision‐making task where reasoning, in contrast, has been found to benefit judgments by making them more stable. The initial assumption in this study was that this benefit would be typical for novel tasks, like the one employed here, and that it would decrease when the task is thoroughly learned. This assumption was examined in three experiments by contrasting it with an alternative assumption that this previously obtained beneficial effect is caused solely by learning, not by reasoning. It was found that learning indeed makes preferences more stable by consolidating the weights of the attributes. Reasoning, however, does not benefit this task when it is completely novel but facilitates learning and stability of the preferences long run, therefore increasing the consistency of the participants in the macrolevel.

Changes in body image during cognitive-behavioral treatment in women with bulimia nervosa

The purposes of this study were: (1) to examine multidimensional aspects of body image of individuals with bulimia nervosa (BN) at pre-treatment, post-treatment, and at follow-up, compared to a group of participants without BN; and (2) to investigate whether measures of body image predicted outcome at post-treatment and follow-up. The clinical sample consisted of 109 females with BN who were enrolled in a 12-week cognitive-behavioral group treatment program. Participants were assessed at baseline, at the completion of treatment, and at 1- and 6-month follow-up visits. The 82 females who comprised the non-bulimic sample were assessed at comparable time intervals. At baseline, the participants with BN reported greater body dissatisfaction and overestimated body size to a significantly greater degree than the comparison group, and reported a significantly smaller ideal size relative to perceived size. Results at the end of treatment indicated significant improvement in self-reported attitudinal disturbance and size overestimation, with continued reductions at follow-up. Logistic regression analyses did not demonstrate a predictive relationship between body image measures at baseline and outcome at post-treatment or follow-up, or between post-treatment and follow-up. Implications for treatment include specifying the source of body image-related distress and enhancing treatment efforts for perceptual and attitudinal aspects of body image.     

ERP correlates of language-specific processing of auditory pitch feedback during self-vocalization

The present study investigated whether the neural correlates for auditory feedback control of vocal pitch can be shaped by tone language experience. Event-related potentials (P2/N1) were recorded from adult native speakers of Mandarin and Cantonese who heard their voice auditory feedback shifted in pitch by −50, −100, −200, or −500 cents when they sustained the vowel sound /u/. Cantonese speakers produced larger P2 amplitudes to −200 or −500 cents stimuli than Mandarin speakers, but this language effect failed to reach significance in the case of −50 or −100 cents. Moreover, Mandarin speakers produced shorter N1 latencies over the left hemisphere than the right hemisphere, whereas Cantonese speakers did not. These findings demonstrate that neural processing of auditory pitch feedback in vocal motor control is subject to language-dependent neural plasticity, suggesting that cortical mechanisms of auditory-vocal integration can be shaped by tone language experience.

The Need for Speed: Agility Selling

In turbulent business times, organizations have sought to become more agile. Organizational agility has been asserted to require workforce agility, but thus far, little focus has been given to workers. Traditionally, salespeople have sought ways to differentiate themselves and create advantage for customers. This paper asserts that, in order to continue this tradition of differentiation and advantage, salespeople must engage in agility thinking. Agility has been studied as it applies to manufacturing processes and other firm activities. Agile salespeople have a mental dexterity at the point of customer contact. They are quick to observe opportunities and are able to anticipate customers’ ever-changing needs, wants, and preferences. This paper presents a framework for agility selling, applying concepts from the agility manufacturing literature and proffering distinct characteristics of sales force agility.     

Strategic differentiation and integration among the 50 states of the USA

Recent studies demonstrate that individuals and populations (at the scale of nations) exhibiting slower life history (LH) speeds are more differentiated amongst themselves with respect to the components of life history. Faster life history individuals and populations are more integrated by comparison. This phenomenon, termed strategic differentiation–integration effort (SD–IE), has not yet been tested on a national scale, however, which is an important remaining step in establishing its generalizability at different levels of aggregation among humans. SD–IE was tested with data on five LH variables from the fifty states of the US. Effects supportive of the SD–IE hypothesis were found in all LH variables, with an average effect magnitude slightly larger than that found in studies of SD–IE at the individual differences level. This is putatively attributed to population stratification, due to the varied racial make-up of the population in the US, including European, African, Native American, and Asian ancestries from multiple countries. This study indicates that SD–IE is a generalizable phenomenon occurring at various levels of aggregation.     

Task relevance modulates processing of distracting emotional stimuli

Relatively little is known about the integration of people's fear-related dispositions and their expectations about stressful events. This research used information integration theory to examine how participants’ anxiety sensitivity and event expectancy are integrated to determine their social anxiety. Three studies were conducted—two with university students and one with anxiety clinic patients—in which participants were presented with multiple scenarios of a socially embarrassing event, each representing a different degree of event probability, from which subjective expectancies were derived. Independent variables included anxiety sensitivity (low, moderate, high) and event expectancy (low, medium, high, no probability information). Participants were asked to indicate their anxiety (dependent measure) in each expectancy condition in this 3 × 4 mixed, quasi-experimental design. The results of all three studies strongly suggest that anxiety sensitivity and event expectancy are integrated additively to produce social anxiety. Additional results and their implications for the treatment of anxiety-related disorders are also discussed.     

A Preliminary Report Comparing Trauma-Focused and Present-Focused Group Therapy Against a Wait-Listed Condition Among Childhood Sexual Abuse Survivors with PTSD

Summary

The movement among states to promulgate, publish, and implement treatment standards for programs and providers of treatment for men who batter has gained increasing momentum in recent years. This movement, in turn, has created controversy. On the one hand, there are those who view the process of standards development, as well as the products, as essentially good and evolving. On the other hand, there are those who have argued that the process has been flawed, exclusionary, and the products based more on philosophy than sound science. The present paper describes the thoughts of a researcher who also served as chair of a state standards committee. The role of research in standards development and evolution is discussed. The role and contribution of researchers to a collaborative process of standards development and implementation is discussed. Suggestions for enhancing the collaborative process are provided.     

L’expérience fraternelle confrontée à la déficience intellectuelle

IntroductionThe present study aims to evaluate the influence of intellectual deficiency on the lifestyle of brothers and sisters.ObjectiveThe objective is to determine whether or not a child's intellectual deficiency has an influence on the nature of the fraternal relationship. We studied the functionality of the familial typology, the feeling of social integration, and the degree of depression in brothers and sisters of children with intellectual disability.MethodThis research was carried out with 34 brothers and sisters of children faced with intellectual disabilities, aged between 6 and 12 years old, and the results were compared with those collected from a test group of 24 children.ResultsThe comparative study shows little differences between siblings and families confronted to intellectual disability and those who are not. The nature of the fraternal relationships differ however as the modality of proximity and conflicts are less expressed by siblings of children faced with intellectual disabilities. Furthermore the correlational study stresses the importance of siblings’ rivalry, the feeling of social integration, and the degree of depression.ConclusionWith these results now uncover risk and protection factors to children confronted to intellectual disabilities among their siblings
