Modus Tollens,Modus Shmollens: Contrapositive reasoning and the pragmatics of negation

The utterance of a negative statement invites the pragmatic inference that some reason exists for the proposition it negates to be true; this pragmatic inference paves the way for the logically unexpected Modus Shmollens inference: “If p then q; not-q; therefore, p.” Experiment 1 shows that a majority of reasoners endorse Modus Shmollens from an explicit major conditional premise and a negative utterance as a minor premise: e.g., reasoners conclude that “the soup tastes like garlic” from the premises “If a soup tastes like garlic, then there is garlic in the soup; Carole tells Didier that there is no garlic in the soup they are eating.” Experiment 2 shows that this effect is mediated by the derivation of a pragmatic inference from negation. We discuss how theories of conditional reasoning can integrate such a pragmatic effect.     

Bullying at work: Epidemiological findings in public and private organizations

Abstract

The aim of the study was to investigate the prevalence of bullying and harassment at work, to identify risk groups and risk organizations, and to investigate who the victims report to be their tormentors. Bullying and harassment are defined as situations where a worker or a supervisor is systematically mistreated and victimized by fellow workers or supervisors through repeated negative acts. However, to be a victim of such bullying one must also feel inferiority in defending oneself in the actual situation. Data from 14 different Norwegian surveys (N = 7986) are presented, encompassing a broad array of organizations and professions. The results show that bullying and harassment at work are widespread problems in Norwegian working life. As many as 8.6% of the respondents had been bullied at work during the previous six months. Organizations with many employees, male-dominated organizations, and industrial organizations had the highest prevalence of victimization. Older workers had a higher risk of victimization than younger workers. Even if men and women do not differ in prevalence of bullying, significantly more men were reported as bullies. Victims reported superiors as bullies as often as they reported colleagues as their tormentor(s).     

Shortcomings of antibullying regulations: The case of Sweden

By means of a qualitative study, the article examines the possible reasons for the apparent shortcomings and limited success of the Swedish statutory regulations against workplace bullying which pioneered and inspired statutory antibullying regulations in other countries following its enactment in 1993. Semistructured interviews were carried out with 18 participants, each with extensive knowledge and experience of the issue, representing employer and trade-union organizations, enforcement authorities, academia, and victim-support organizations. A range of potential reasons for its limited success emerged from the study, encompassing shortcomings associated with the involvement (or lack of involvement) of key actors—employers, trade unions, and labour inspectorate, and with the antibullying regulatory framework itself. In addition, some cultural and socioeconomic conditions may also have hampered its effectiveness and success. In light of these findings the study raises questions about how to regulate for intangible issues such as bullying. However, the Swedish Ordinance against bullying has contributed to giving the issue credibility. Yet, in order to be successful, legal interventions must be accompanied by well-informed, trained, and motivated employers and trade unions who, in collaboration, are willing to deal with the problem proactively on an organizational level as well as responding to individual cases when they occur, supported by an enforcement agency or inspectorate which is equipped and geared up for its role.     

Neuropsychological performance in older insomniacs

ABSTRACT

The purpose of this study was to examine daytime performance in older adults fulfilling the diagnostic criteria for DSM-IV Insomnia, using a comprehensive battery of neuropsychological tests, and to compare these objective findings with measures of self-reported cognitive functioning. A total of 121 participants (69% women) with a mean age of 64.0 were part of a thorough neuropsychological examination at a University-based neuropsychological clinic in Western Norway. Twenty-five percent of the participants fulfilled the diagnostic criteria for insomnia. In sum, the insomnia patients were not different from the good sleepers on any neuropsychological test measure, and none of the results on the performance measures were associated with the sleep-related daytime complaints. However, the insomniacs did rate their subjective memory performance as significantly worse than the good sleepers, and they also reported more depressive symptoms. We conclude that DSM-IV defined insomnia was not associated with any performance based measure; only with self-reported symptoms.     

Collected Stories: Play in Four Acts

This article evolved from a group process where members of a psychoanalytic institute were faced with planning workshops for a professional weekend around the theme of “play.” The workshop that evolved consisted of four vignettes of play taking place in the therapeutic sessions of a child, an adolescent, an adult, and an elderly woman. The discussion of these vignettes that began at the conference and then was developed for this article focuses on tracing the development of play from childhood into adulthood (Mayes & Cohen, 1996; Russ, 2004) and on the relationship between play and the development of reflective functioning (Fonagy & Target, 1996). One area of particular interest that was focused upon was the use of play with adults who are described as “concrete,” people who function, at times, at a level of differentiation more typical of a young child. Play is described as being particularly helpful in facilitating a more differentiated and, thus, more reflective mode of psychic functioning for this group of individuals as well as for people at all levels of development.     

Co-occurrence frequency evaluated with large language corpora boosts semantic priming effects

In recent decades, many computational techniques have been developed to analyse the contextual usage of words in large language corpora. The present study examined whether the co-occurrence frequency obtained from large language corpora might boost purely semantic priming effects. Two experiments were conducted: one with conscious semantic priming, the other with subliminal semantic priming. Both experiments contrasted three semantic priming contexts: an unrelated priming context and two related priming contexts with word pairs that are semantically related and that co-occur either frequently or infrequently. In the conscious priming presentation (166-ms stimulus-onset asynchrony, SOA), a semantic priming effect was recorded in both related priming contexts, which was greater with higher co-occurrence frequency. In the subliminal priming presentation (66-ms SOA), no significant priming effect was shown, regardless of the related priming context. These results show that co-occurrence frequency boosts pure semantic priming effects and are discussed with reference to models of semantic network.     

Squaring the round: An unusual progressive graphomotor impairment with post‐mortem findings

Investigations of neurodegenerative disorders may reveal functional relationships in the cognitive system. C.S. was a 63‐year‐old right‐handed man with post‐mortem confirmed Pick's disease with a range of progressive impairments including non‐fluent aphasia, speech, limb, oculomotor, and buccofacial apraxia, but mostly intact intelligence, perception, orientation, memory, semantics, and phonology. During progression, agrammatism in writing with impairments in syntactic comprehension emerged in parallel with an unusual graphomotor deficit in drawing and writing, with an increasing deterioration of graphic short‐term memory. We investigated C.S.'s graphomotor deficit longitudinally using tests of writing and drawing on letters, words, and sentences and drawing to command and copying. We also tested C.S.'s short‐term graphemic buffer experimentally. Analysis showed deficits on selective aspects of graphomotor implementation of writing and drawing, mainly affecting the production of circles and curves, but not short straight lines in drawing and writing, and graphomotor short‐term memory, which paralleled impairments of written syntax and syntactic comprehension. We believe this to be the first detailed analysis of such an unusual progressive impairment in graphomotor production, which may be related to problems with agrammatic agraphia and impairments affecting shared components of cognition reflecting damage to shared neural networks. Alternatively, they may simply reflect the effects of coincidental damage to separate mechanisms responsible for aspects of writing, drawing, and syntactic processing. Longitudinal investigations of emerging deficits in progressive conditions like C.S.'s provides an opportunity to examine the progressive emergence of symptoms in an individual with multiple progressive impairments as they appear and examine putative relationships between them.     

Seeking positive experiences can produce illusory correlations

Individuals tend to select again alternatives about which they have positive impressions and to avoid alternatives about which they have negative impressions. Here we show how this sequential sampling feature of the information acquisition process leads to the emergence of an illusory correlation between estimates of the attributes of multi-attribute alternatives. The sign of the illusory correlation depends on how the decision maker combines estimates in making her sampling decisions. A positive illusory correlation emerges when evaluations are compensatory or disjunctive and a negative illusory correlation can emerge when evaluations are conjunctive. Our theory provides an alternative explanation for illusory correlations that does not rely on biased information processing nor selective attention to different pieces of information. It provides a new perspective on several well-established empirical phenomena such as the ‘Halo’ effect in personality perception, the relation between proximity and attitudes, and the in-group out-group bias in stereotype formation.     

Functional magnetic resonance imaging study of Piaget's conservation-of-number task in preschool and school-age children: a neo-Piagetian approach

Jean Piaget’s theory is a central reference point in the study of logico-mathematical development in children. One of the most famous Piagetian tasks is number conservation. Failures and successes in this task reveal two fundamental stages in children’s thinking and judgment, shifting at approximately 7 years of age from visuospatial intuition to number conservation. In the current study, preschool children (nonconservers, 5-6 years of age) and school-age children (conservers, 9-10 years of age) were presented with Piaget’s conservation-of-number task and monitored by functional magnetic resonance imaging (fMRI). The cognitive change allowing children to access conservation was shown to be related to the neural contribution of a bilateral parietofrontal network involved in numerical and executive functions. These fMRI results highlight how the behavioral and cognitive stages Piaget formulated during the 20th century manifest in the brain with age.     

Narrative means to manage responsibility in life narratives across adolescence

Adolescence is a passage from dependence to adult responsibility. Alongside identity development, social-cognitive development, and the ability to construct a life story, adolescents become increasingly aware of both their potential responsibility in an expanded sphere of life and of complex, contextual influences on their lives. This was partially tested in a cross-sectional study, both in terms of linguistic means and content expressed in life narratives. Indicators were defined for narrative agency, grading of responsibility, serendipity, and turning points, and tested for age differences in relative frequencies in 102 life narratives from age groups of 8, 12, 16, and 20 years, balanced for gender. Narrative grading of responsibility, serendipity, and turning points increased throughout adolescence. The relative frequency of narrative agency, in contrast, remained constant across age groups. Results are interpreted in the context of adolescent development of narrative identity.
