Morningness-eveningness in adolescents

Individual morningness-eveningness differences explain the rhythmic variations of behavioral and biological patterns. Several studies have corroborated that morningness preference increases over adulthood and aging. Adolescents shift their time of day preferences from morningness to eveningness during puberty. The aims of this study were translate to Spanish the Morningness-Eveningness Scale for Children (MESC) and to analyze age and sex differences. A group of 600 adolescents (aged between 12 and 16 years) participated in the study. Psychometric analysis showed that reliability and factor structure were suitable and similar to previous studies. The results indicated a clear decrease of morningness as of 12 years. Boys were more morningness-oriented than girls in several items of the questionnaire. In view of the results, several educational implications are raised.     

Rotating item banks versus restriction of maximum exposure rates in computerized adaptive testing

If examinees were to know, beforehand, part of the content of a computerized adaptive test, their estimated trait levels would then have a marked positive bias. One of the strategies to avoid this consists of dividing a large item bank into several sub-banks and rotating the sub-bank employed (Ariel, Veldkamp & van der Linden, 2004). This strategy permits substantial improvements in exposure control at little cost to measurement accuracy, However, we do not know whether this option provides better results than using the master bank with greater restriction in the maximum exposure rates (Sympson & Hetter, 1985). In order to investigate this issue, we worked with several simulated banks of 2100 items, comparing them, for RMSE and overlap rate, with the same banks divided in two, three... up to seven sub-banks. By means of extensive manipulation of the maximum exposure rate in each bank, we found that the option of rotating banks slightly outperformed the option of restricting maximum exposure rate of the master bank by means of the Sympson-Hetter method.     

Needs and Cognition/Behavior Patterns at Work and the Big Five: An assessment of the Personality and Preference Inventory‐Normative (PAPI‐N) from the perspective of the five‐factor model

This study examined the relationship between psychological needs and cognition/behavior patterns at work as measured by the Personality and Preference Inventory – Normative (PAPI‐N) and the five‐factor model of personality as measured by the NEO Five Factor Inventory (NEO‐FFI) in a sample of 91 working adults and 71 psychology undergraduates who worked or had some work experience. Our results showed significant and theoretically congruent correlations between the PAPI‐N scales and the measures of the five‐factor model. These correlations were similar to those found using alternative instruments to measure Murray's needs. Despite the differences in the conceptual origins of the PAPI‐N and the NEO‐FFI and divergences in the aspects of personality measured by the two inventories, joint and interbattery factor analyses showed that most of the needs and cognition/behavior patterns measured by the PAPI‐N can be meaningfully organized within the framework of the five‐factor model. These results provide further empirical evidence for the validity of the five‐factor model and the PAPI‐N, although they also point out personality aspects that are not encompassed by the five‐factor model.     

Mental representations of obligatory and prohibitory traffic signs

Every traffic sign conveys a single proposition about traffic conditions. Drivers must integrate this proposition with their goals and other known facts to decide on an appropriate action in what amounts to a deduction task. For example, imagine that you are driving a car and you want to turn right at an intersection but there is a no right turn sign. You have to assess the options and make a decision (reach a conclusion). Theoretical accounts from research about reasoning can be applied to how we understand traffic signs and make inferences from them. This study includes two experiments that analysed how people decide whether a situation is allowed or not, taking into account the information provided by one sign - obligatory or prohibitory - or two signs - two obligatory or two prohibitory signs. The number of signs, that is, the complexity of the driving scene, was a key factor in this study. The two experiments differ in the presentation format of the two-sign experimental condition. In the first experiment, the signs were presented as two isolated signs. In the second experiment, the two signs were embedded in one. Equivalent results were found whether two isolated signs or two embedded signs were shown. When an obligatory sign was used at the junction, faster responses were obtained for allowed manoeuvres than for those not allowed. When a prohibitory sign was used, the results were the opposite. However, the advantage of prohibitory signs in the not-allowed situation was not replicated when people had to collect information from two prohibitory signs. Results showed that people integrate two obligatory sign messages - informing where one can go - more easily than two prohibitory sign messages - informing where not to go. Therefore, it could be said that each traffic sign elicits an internal mental model elaboration in which forbidden actions are explicitly labelled by means of attached "mental footnotes" indicating the epistemic status of "prohibitory information."     

Effects of SB-205384, a positive modulator of alpha3-subunit-containing GABA-A receptors, on isolation-induced aggression in male mice

GABA-A receptors are involved in the control of aggressive behaviour. Various studies suggest a role for a1-containing GABA-A receptors in modulating aggression. However, the possible involvement of a3 subunit of GABA-A receptors has not been examined. In this study, we analysed the effect of SB-205384 (0.5-4 mg/kg, i.p), a positive modulator of GABA-A receptors containing a3 subunit, on agonistic behaviour elicited by isolation in male mice. Half of the mice were housed during 30 days and employed as experimental or control animals; the remainder were used as and were temporally rendered anosmic by zinc sulphate. Individually housed mice were exposed to anosmic opponents in a neutral area 30 minutes after the drug administration and encounters were videotaped and evaluated using an ethopharmacologically-based analysis. The results indicated that SB-205384 did not produce any significant behavioural changes, suggesting that GABA-A receptors which contain the a3 subunit may not be involved in the modulation of aggression.     

The International Affective Digitized Sounds (IADS): Spanish norms

The International Affective Digitized Sounds (IADS): Spanish Norms. The Spanish norms for the International Affective Digitized Sounds (IADS) are reported. The IADS is a standardized set of 110 digitalized sounds which are both reliable and valid for the experimental study of emotional processes. The construction of the IADS is based on Peter J. Lang's dimensional model of emotions. Participants were 1.716 university students (1.136 women) who assessed the sounds using the three scales of the Self-Assessment Manikin: affective valence, arousal, and dominance. The results show a distribution of the sounds, within the bidimensional plot defined by valence and arousal, similar to the North-American student population with a typical boomerang shape. No significant differences were found when comparing men and women nor when comparing the Spanish and North-American samples in the total set of sounds. The results are discussed in relation to the International Affective Picture System (IAPS). The norms for each of the 110 sounds are presented in an annexed table.     

Mood state indicators for adolescent athletes based on POMS multidimensional model

In this paper, we offer a short version of the POMS, with only 33 items, designed to apply to young Spanish athletes. One hundred and six male soccer players, aged 14 and 15 years, participated in the study. In order to select the proposed items, we tried to maximize three criteria: (1) items should be understood by subjects, (2) items should be perceived as conceptually similar as possible to the meaning of their respective factors, and (3) every factor should contain at least 4 items. To meet the second criterion, PROXSCAL scaling procedure was used, which allowed retaining the items closest to the meaning of each factor. All goodness-of-fit indexes were satisfactory in all the proximity analyses performed. In the proposed POMS version, the 33 items refer to seven mood factors, as follows: Tension (4 items), Depression (9 items), Anger (4 items), Vigour (4 items), Fatigue (4 items), Confusion (4 items), and Friendliness (4 items).     

Using morphology when spelling in a shallow orthographic system: The case of Spanish

Deep orthographies usually represent morphology and phonology simultaneously; both resources are necessary for spelling. In shallow orthographies, such as Spanish, phonology would be enough to spell most words. However, morphological knowledge may also take part in spelling. This study examined how Spanish children in 1st (N = 148), 2nd (N = 155) and 3rd grade (N = 155) use morphological information to spell plural nouns and verbs. A word dictation task was designed. The task included high and low frequency plural nouns ending in “s” (morphological “-s” condition) and verbs in the 2nd person ending in “s” (morphological “-s” condition). A lexical condition including words with a final “s” which was not morphologically motivated was used as a control condition (lexical “-s” condition). The results show that, although Spanish spelling is influenced by phonology, morphological information is also used. These results are discussed in relation to current models of word spelling.     

Designing Organizations: Does Expertise Matter?

From an organizational cognition standpoint, we approach organizational design as an ongoing creative sensemaking process. This study examined the role of expertise in the cognitive problem-solving patterns underlying design processes and the resulting organizational forms. The simulated problem elicited the mental models applied by naives, novices, and experts in designing an organization. The thinking-aloud protocol analysis revealed quantitative and qualitative expert/nonexpert differences in problem-solving strategies, the time spent on problem representation, and the justifications and difficulties expressed in the course of the design process. In addition, our results showed that naives created organizations consistent with mechanistic structures, while novices and experts created organizations consistent with organic structures. We discuss the implications of these findings for the understanding of the cognitive basis of organizational design and the development of effective training programs.
