The Identity Issues Inventory: Identity Stage Resolution in the Prolonged Transition to Adulthood

The Identity Issues Inventory (I₃) uses an Eriksonian framework to assess identity stage resolution among those experiencing a prolonged transition to adulthood in terms of the developmental tasks of self-identity formation (integration and differentiation) and societal-identity formation (work roles and worldview). For this first analysis of this new measure, data were collected from two samples: (1) 196 people between the ages of 18 and 48 and (2) 1,489 participants between the ages of 18 and 41. Overall, the I₃ yields good factorial validity and reliability, and scores increase with age toward the “ceiling” of each task subscale, which represent anchors of a stable adult identity. Structural equation modeling assessed the relationships between these prominent identity issues and psychological health, revealing a positive relationship between the two constructs, providing evidence for predictive validity. An analysis of the second sample of 1,498 people confirmed these findings. The I₃ promises to be a useful tool in future investigations of identity stage resolutions for those aged 18 and above experiencing a prolonged transition to adulthood.     

Long-tailed macaques display unexpected waiting abilities in exchange tasks

The ability of animals to delay gratification is crucial for complex goal-directed action. It may help them in making effective decisions when facing a choice. We tested the ability of nine long-tailed macaques (Macaca fascicularis) to delay gratification in several experiments. In exchange tasks, subjects had to keep a small piece of cookie before returning it to an experimenter in order to get a larger food amount. Results showed that animals could wait between 10 s and 10 min depending on individual and sizes of reward. In another experiment, subjects could immediately give back the initial piece of cookie then wait for the return. Their performances more than doubled, demonstrating the role of consumption inhibition in postponing gratification. Such achievements underscore delays of gratification which until now were not thought possible in monkeys. Finally, subjects were presented with an accumulation of food pieces added at short intervals until they seized them. They mostly waited between 30 s and 1 min, which points at the consistency of our data, compared to those of other studies. Our results indicate that long-tailed macaques anticipated the duration of delays. We may account for their remarkable performances by their achievements in the social context.     

Functional cerebral changes in multiple sclerosis patients during an autobiographical memory test

Our aim was to investigate the functional underpinnings of autobiographical memory (AM) impairment in multiple sclerosis (MS) patients. To that end, 18 patients and 18 controls underwent the autobiographical interview (AI). Subsequently, the 36 participants underwent a functional magnetic resonance imaging (fMRI) session designed to assess the construction and elaboration of AMs. A categorical control task was also presented. Patients were trained in the fMRI procedure to optimise the procedural aspects accompanying the task itself. Although the patients obtained significantly poorer AI scores (p < .001), their performance on the easier AM fMRI task was efficiently carried out, allowing relevant comparisons with healthy controls. Relatively to healthy controls, the patients showed increased and bilateral cerebral activations (p < .005) during the construction and elaboration phases. The prefrontal, temporal and posterior cerebral region activations were located within the core network sustaining AM, with the bilateral prefrontal region being centrally involved. The parametric neural responses to the difficulty of access and amount of details of memories were also significantly different for the two groups, with the right hippocampal region showing a particularly increased recruitment (p < .005). The findings suggested the presence of functional cerebral changes during AM performance and supported the presence of AM retrieval deficit in MS patients.     

Effect of a retention interval between pre-exposure and conditioning on latent inhibition in humans using a blink conditioning procedure

Latent inhibition, retarded learning after pre-exposure to the to-be-conditioned stimulus, was examined using a blink conditioned procedure in humans. Experiment 1 showed that the procedure is suited to inducing the latent inhibition effect. In Experiment 2, the introduction of a 3-minute interval between pre-exposure and conditioning phases attenuated latent inhibition. These results contribute to identify the mechanisms involved in pre-exposure and subsequent conditioning of a stimulus, which is particularly important if we bear in mind that latent inhibition has been used repeatedly as an instrument to analyze the course of attentional processes in normal and pathological populations.     

Gradual remapping results in early retinotopic and late spatiotopic inhibition of return

Here we report that immediately following the execution of an eye movement, oculomotor inhibition of return resides in retinotopic (eye-centered) coordinates. At longer postsaccadic intervals, inhibition resides in spatiotopic (world-centered) coordinates. These results are explained in terms of perisaccadic remapping. In the interval surrounding an eye movement, information is remapped within retinotopic maps to compensate for the retinal displacement. Because remapping is not an instantaneous process, a fast, but gradual, transfer of inhibition of return from retinotopic to spatiotopic coordinates can be observed in the postsaccadic interval. The observation that visual stability is preserved in inhibition of return is consistent with its function as a "foraging facilitator," which requires locations to be inhibited across multiple eye movements. The current results support the idea that the visual system is retinotopically organized and that the appearance of a spatiotopic organization is due to remapping of visual information to compensate for eye movements.     

New Wine in a New Bottle: Refining The Assessment of Authentic Leadership Using Exploratory Structural Equation Modeling (ESEM)

The aim of this study was to investigate the multidimensional nature of authentic leadership (AL) through the re-evaluation of the factor structure of the most commonly used scales in AL research, the Authentic Leadership Questionnaire (ALQ) and the Authentic Leadership Inventory (ALI). Results from Exploratory Structural Equation Modeling (ESEM) conducted among 538 workers of private (57,81%) and public (42,19%)? organizations provide support for the multidimensional nature of AL but also reveal excessive content overlap across subscales and an inability to properly reflect the a priori factor structure of both instruments. Further analyses enabled the identification of key items from both instruments providing a cleaner depiction of the a priori dimensionality of AL, leading to the development of an integrated optimized measure, the Authentic Leadership Integrated Questionnaire (AL-IQ). The main contribution of this study is the proposition of an alternative and optimized measure of authentic leadership that sheds light on the distinct theoretical facets of this positive leadership style. Our data suggest that the AL-IQ is a promising tool for characterizing the strengths and weaknesses of leaders and managers’ AL practices. To our knowledge, this is the first study to use a combination of classical Confirmatory Factor Analyses (CFA) and newly developed ESEM framework to assess the construct validity (factor structure, reliability, and criterion-related validity) of the two main AL measures: the ALQ and the ALI.     

Short Spanish version of Team Climate Inventory (TCI-14): development and psychometric properties

The aim of the present paper was to develop a Spanish adaptation of the reduced, 14-item version of the Team Climate Inventory (TCI-14), a questionnaire developed to evaluate team climate. To this end the English version was adapted and applied to a sample of 360 employees from Castilla-León and Catalonia (44.4% men and 55.6% women). The results indicated that the TCI-14 has the same structure as the original version, and confirmatory factor analysis was used to verify the existence of the factors Vision, Participative Safety, Task Orientation and Support for Innovation. The TCI-14 also presented good reliability coefficients considering the low number of items on each scale (alphas ranged between .75 and .82). The TCI-14 is a potentially useful instrument for evaluating the climate of work teams. It could be used by future research as a screening tool in conjunction with other instruments.     

Removing Inconsistencies in Assumption-based Theories Through Knowledge-Gathering Actions

In this paper, the problem of purifying an assumption-based theory KB, i.e., identifying the right extension of KB using knowledge-gathering actions (tests), is addressed. Assumptions are just normal defaults without prerequisite. Each assumption represents all the information conveyed by an agent, and every agent is associated with a (possibly empty) set of tests. Through the execution of tests, the epistemic status of assumptions can change from "plausible" to "certainly true", "certainly false" or "irrelevant", and the KB must be revised so as to incorporate such a change. Because removing all the extensions of an assumption-based theory except one enables both identifying a larger set of plausible pieces of information and renders inference computationally easier, we are specifically interested in finding out sets of tests allowing to purify a KB (whatever their outcomes). We address this problem especially from the point of view of computational complexity.
