On the psychology of time in action: regulatory mode orientations and procrastination

Six studies explored the relations of the regulatory modes of locomotion and assessment to individuals' tendency toward procrastination. Across academic and organizational contexts, and a variety of ways of assessing procrastination, the authors found assessment to be positively related to procrastination and locomotion to be negatively related to procrastination. Discussion considered implications of these findings to task environments that may instill the tendencies toward locomotion or assessment and to task requirements where timeliness and punctuality are (or are not) prioritized.     

Mass nouns,vagueness and semantic variation

The mass/count distinction attracts a lot of attention among cognitive scientists, possibly because it involves in fundamental ways the relation between language (i.e. grammar), thought (i.e. extralinguistic conceptual systems) and reality (i.e. the physical world). In the present paper, I explore the view that the mass/count distinction is a matter of vagueness. While every noun/concept may in a sense be vague, mass nouns/concepts are vague in a way that systematically impairs their use in counting. This idea has never been systematically pursued, to the best of my knowledge. I make it precise relying on supervaluations (more specifically, ‘data semantics’) to model it. I identify a number of universals pertaining to how the mass/count contrast is encoded in the languages of the world, along with some of the major dimensions along which languages may vary on this score. I argue that the vagueness based model developed here provides a useful perspective on both. The outcome (besides shedding light on semantic variation) seems to suggest that vagueness is not just an interface phenomenon that arises in the interaction of Universal Grammar (UG) with the Conceptual/Intentional System (to adopt Chomsky’s terminology), but it is actually part of the architecture of UG.     

How stressful is retirement! Antecedents of stress linked to athletes’ career termination

A field study conducted with professional athletes (N = 420, 72.2% men, M_age = 25.14) examined the antecedents of stress linked to career termination. We hypothesized that stress linked to career termination may be affected by the type of passion (harmonious and obsessive) athletes develop for their sport activity, and that this passion may be affected by regulatory mode orientations (locomotion and assessment) and need for closure (NFC). The present findings confirm our hypotheses that locomotion positively predict stress linked to career termination through a partial mediation of harmonious passion, while assessment and NFC negatively predict stress through the mediation of obsessive passion. In conclusion, this study provides further information to existing intervention programs aimed at preventing the negative consequences related to athletes’ career termination.     

A comparative analysis of the effects of alienation on public and private school females

The levels of alienation of American female school students (N = 431; 256 public, 175 private) were assessed to determine the extent of the influence of the school environment on the student's level of alienation and the dimensions of isolation, normlessness, and powerlessness. It was hypothesized that substantially different school settings would have no significant effects because student alienation is influenced by a series of complex environmental factors. The Dean Alienation Scale (1961) was used to assess levels of alienation. There were no significant differences in terms of total alienation and powerlessness. Private school students, however, were more isolated (p less than .001) and public school students had higher levels of normlessness (p less than .05).     

The Logic of Quantum Measurements in terms of Conditional Events

This paper shows that the non-Boolean logic of quantum measurementsis more naturally represented by a relatively new 4-operationsystem of Boolean fractions—conditional events—thanby the standard representation using Hilbert Space. After therequirements of quantum mechanics and the properties of conditionalevent algebra are introduced, the quantum concepts of orthogonality,completeness, simultaneous verifiability, logical operations,and deductions are expressed in terms of conditional eventsthereby demonstrating the adequacy and efficacy of this formulation.Since conditional event algebra is nearly Boolean and consistsmerely of ordered pairs of standard events or propositions,quantum events and the so-called "superpositions" of statesneed not be mysterious, and are here fully explicated. Conditionalevent algebra nicely explains these non-standard "superpositions"of quantum states as conjunctions or disjunctions of conditionalevents, Boolean fractions, but does not address the so-called"entanglement phenomena" of quantum mechanics, which remainphysically mysterious. Nevertheless, separating the latter phenomenafrom superposition issues adds clarity to the interpretationof quantum entanglement, the phenomenon of influence propagatedat faster than light speeds. With such treacherous possibilitiespresent in all quantum situations, an observer has every reasonto be completely explicit about the environmental–instrumentalconfiguration, the conditions present when attempting quantummeasurements. Conditional event algebra allows such explicationwithout the physical and algebraic remoteness of Hilbert space.     

Gender differences in object location memory in a real three-dimensional environment

In this preliminary study we investigate gender differences in object location memory. Our purpose is to extend the results about object location memory obtained in laboratory settings to a real 3-D environment and to further distinguish the specific components involved in this kind of memory by considering the strategies adopted to perform the task. To do this, we join the three-level model of spatial representations (landmark, route, and survey) proposed by Siegel and White (1975) with the three subcomponents of spatial memory (what, where, and what + where) identified by Postma and De Haan (1996). We adopted the object relocation task devised by Postma and De Haan (1996), adapted to a real environment. Seven common objects were placed on the floor of a cylindrical room. Sixty-four males and 64 females were asked to memorize the spatial layout. Next, the experimenter moved the objects to a different position along with seven new objects and the participants had to relocate the original objects to their initial positions. In line with Postma, Izendoorn, and De Haan (1998), we found no gender difference in object recognition, and in recalling absolute distance and categorical spatial relations; however males were better than females in recalling the distance between objects and the size of the layout. Overall, the data show a male advantage in some components of spatial cognition closely linked to the encoding of the metric structure of the spatial relationships at both route and survey level.     

Alienation: a cause of juvenile delinquency

This research investigated differences in levels of alienation between incarcerated (n = 157) and nonincarcerated (n = 1,318) adolescents. It was hypothesized that incarcerated adolescents would have significantly higher levels of isolation, normlessness, powerlessness, and total alienation than would nonincarcerated adolescents. The Dean Alienation Scale, a global measure of alienation, was administered to all subjects. Results indicated that incarcerated adolescents had significantly higher levels of total alienation, isolation, and powerlessness. Given the high rates of recidivism, these results suggest that the reduction of both alienation and rejection of societal norms should be a major component of rehabilitation programs for incarcerated juvenile delinquents.     

Motor resources in peripersonal space are intrinsic to spatial encoding: Evidence from motor interference

The aim of this study was to explore the role of motor resources in peripersonal space encoding: are they intrinsic to spatial processes or due to action potentiality of objects? To answer this question, we disentangled the effects of motor resources on object manipulability and spatial processing in peripersonal and extrapersonal spaces. Participants had to localize manipulable and non-manipulable 3-D stimuli presented within peripersonal or extrapersonal spaces of an immersive virtual reality scenario. To assess the contribution of motor resources to the spatial task a motor interference paradigm was used. In Experiment 1, localization judgments were provided with the left hand while the right dominant arm could be free or blocked. Results showed that participants were faster and more accurate in localizing both manipulable and non-manipulable stimuli in peripersonal space with their arms free. On the other hand, in extrapersonal space there was no significant effect of motor interference. Experiment 2 replicated these results by using alternatively both hands to give the response and controlling the possible effect of the orientation of object handles. Overall, the pattern of results suggests that the encoding of peripersonal space involves motor processes per se, and not because of the presence of manipulable stimuli. It is argued that this motor grounding reflects the adaptive need of anticipating what may happen near the body and preparing to react in time.
