Creativity and innovation at work: the role of work characteristics and personal initiative

In this longitudinal study, we examined the role of work characteristics (creative requirement, job control, coworker and supervisor support) and personal initiative for teachers' idea generation, idea promotion, and idea implementation. Eighty-nine teachers responded to two surveys with an interval of two weeks. Hierarchical regression analyses showed that creative requirement and job control predicted idea generation, whereas support from coworkers and the supervisor predicted idea promotion. Coworker and supervisor support, as well as teachers' personal initiative, predicted idea implementation.     

A neurocognitive model of meditation based on activation likelihood estimation (ALE) meta-analysis

Meditation comprises a series of practices mainly developed in eastern cultures aiming at controlling emotions and enhancing attentional processes. Several authors proposed to divide meditation techniques in focused attention (FA) and open monitoring (OM) techniques. Previous studies have reported differences in brain networks underlying FA and OM. On the other hand common activations across different meditative practices have been reported. Despite differences between forms of meditation and their underlying cognitive processes, we propose that all meditative techniques could share a central process that would be supported by a core network for meditation since their general common goal is to induce relaxation, regulating attention and developing an attitude of detachment from one's own thoughts. To test this hypothesis, we conducted a quantitative meta-analysis based on activation likelihood estimation (ALE) of 10 neuroimaging studies (91 subjects) on different meditative techniques to evidence the core cortical network subserving meditation. We showed activation of basal ganglia (caudate body), limbic system (enthorinal cortex) and medial prefrontal cortex (MPFC). We discuss the functional role of these structures in meditation and we tentatively propose a neurocognitive model of meditation that could guide future research.     

Narrative, meaning, interpretation: an enactivist approach

After establishing its roots in basic forms of sensorimotor coupling between an organism and its environment, the new wave in cognitive science known as ??enactivism?? has turned to higher-level cognition, in an attempt to prove that even socioculturally mediated meaning-making processes can be accounted for in enactivist terms. My article tries to bolster this case by focusing on how the production and interpretation of stories can shape the value landscape of those who engage with them. First, it builds on the idea that narrative plays a key role in expressing the values held by a society, in order to argue that the interpretation of stories cannot be understood in abstraction from the background of storytelling in which we are always already involved. Second, it presents interpretation as an example of what Di Paolo et al. (2010) have called in their recent enactivist manifesto a ??joint process of sensemaking??: just like in face-to-face interaction, the recipient of the story collaborates with the authorial point of view, generating meaning. Third, it traces the meaning brought into the world by interpretation to the activation and, potentially, the restructuring of the background of the recipients of the story.     

Self-body recognition depends on implicit and explicit self-esteem

The present contribution bridges research on body image, self-esteem, and body recognition. Recent work in neuroscience indicates a superiority in the processing of self relative to others’ body parts. The present contribution shows that this ability is not universal but it is qualified by individual differences in implicit and explicit self-esteem. In fact, two studies (n₁ = 41 and n₂ = 35) using two different paradigms in body recognition and direct and indirect measures of self-esteem reveal that this advantage in recognizing one's own body parts is associated with one's level of self-esteem. Moreover, it appears that measures of implicit and explicit self-esteem provide different contributions to self-body recognition abilities and that these contributions depend on how self-body recognition is assessed. Implications of these results are discussed notably in the perspective of research on body image.     

Sensing Aliveness

This study examines whether the categories animate/inanimate might be formed on the basis of information available to the cognitive system. We suggest that the discrimination of percepts according to these categories relies on proprioceptive information, which allows the perceiving subject to know that he is ‘animate’. Since other ‘objects’ in the world exhibit movements, reactions, etc. similar to those that the subject experiences himself, he can ‘project’ his knowledge onto these objects and recognize them as ‘animate’ like himself. On this basis we try to corroborate the empricist position in the debate concerning the organization of knowledge as opposed to the nativist view. Furthermore, we argue that the categorical dichotomy animate/inanimate is more basic than other analogous ones such as living/non-living, biological/non-biological and we sketch a ‘categorical stratification’ following the line ‘humans–animals–plants’ based on the hypothesis that humans detect different degrees of ‘vitality’ according to the degree of similarity they recognise between the considered instance and themselves.     

Multiple mechanisms for recency with vowels and consonants

Three experiments were conducted to test the hypothesis that the difference in recency effect between vowel-contrasting and stop-contrasting lists of syllables in immediate ordered recall can be explained by item discriminability and regular short-term memory mechanisms, without any recourse to echoic memory or precategorical acoustic storage (PAS). In Experiment 1, the short-term memory mechanisms were manipulated by reducing amount of output interference and length of retention interval. The partial-report technique was used. The most important finding was the usual final-position recency effect (difference in recall between the fifth and sixth serial positions) for the vowel lists but not for the stop lists, regardless of the type of report. Thus the PAS theory could not be rejected. In Experiments 2 and 3, the last item was differentiated from the other items of the list, either by lengthening the interstimulus interval between the last and the next-to-last (Experiment 2) or by increasing the intensity of the last item (Experiment 3). In both cases, an increase of the final-position recency effect was found even for stop lists. Since a drop in recall errors was also obtained for the fourth item when its intensity was increased (von Restorff effect), this final-position recency effect for stop lists is likely to be due to item discriminability, and not to echoic memory for the last item. Item discriminability appeared to be the critical factor.     

Judgmental relativism as a validity threat to standardized psychiatric rating scales

Judgemental relativism is a threat to the replicability and validity of measures of client behavior from direct rating scales whenever raters are exposed to different levels of client functioning since the internal standards, or anchor points, used to judge dimensional continua may vary on the basis of prior experience. Traditional interrater reliability indexes fail to identify such effects. The influence of judgmental relativism on summated ratings from the Nurses Observational Scale for Inpatient Evaluation (NOSIE-30) for 1040 adult mentally ill clients was examined with clinical staff raters from 24 treatment units in which the Time-Sample Behavioral Checklist (TSBC) provided full-week objective measures of actual client functioning via hourly direct observational coding (DOC). Regression analyses found that the same level of objective performance received higher or lower ratings across treatment units dependent on the raters'exposure to client groups that differed in level of functioning. Analyses of rating errors found that clients with better levels of functioning relative to others within treatment units were rated even higher than performance warranted. The operation of halo and contrast effects is explored and guidelines are provided for determining when judgmental relativism may produce or nullify significant differences. DOC assessments should be used instead of retrospective ratings to support most decisions in residential settings. Specific recommendations for the application of rating scales and improving data quality are provided.This study was the basis of a master's thesis at the University of Houston by Betty E. Rich under the direction of Gordon L. Paul and Marco J. Mariotto. Richard M. Rozelle, to whom appreciation is expressed for helpful comments, served on the examination committee. This study was partially supported by grants to Gordon L. Paul from the National Institute of Mental Health, Public Health Service (MH-15353; MH-25464); the Illinois Department of Mental Health and Developmental Disabilities; the Joyce Foundation; the MacArthur Foundation; the Owsley Foundation; the Cullen Foundation; and the Center for Public Policy, University of Houston.     

Anxiety, perceptual and motor skills in an underwater environment

This research has analyzed the perceptual and motor skills in an underwater environment at 30 m of 24 subjects differing in diving experience. The State-Trait Anxiety Inventory, Form X-1, was administered to evaluate possible changes in anxiety associated with hyperbaric conditions during the perceptual and motor task. Analysis indicates that in comparison with experienced divers, less experienced divers showed a performance decrement. No changes in anxiety were observed.     

Personality described by adjectives: The generalizability of the Big Five to the Italian lexical context

Two studies have been performed in the frame of the Big Five model to describe personality. In the first study, the most useful adjectives for describing personality have been selected, trying to adopt a procedure as objective and empirically driven as possible. The resulting pool of adjectives (n = 492) has been administered to a sample of 274 subjects to verify the emergence of the Big Five in the Italian context. In the second study the pool of original adjectives has been reduced to 260 adjectives selecting the most representative terms (with regard to the factorial structure that has emerged). This pool of 260 adjectives has been administered to a sample of 862 subjects, together with the NEO-PI and the BFQ to facilitate the interpretation of the resulting factorial structure. Results showed the emergence of an Italian Big Five factorial structure that resembles the ‘canonical’ Big Five, although some of the factors, viz. Agreeableness and Emotional Stability, emerged as ‘blended’ dimensions.
