Dimensional proposal to assess humor appreciation

The aim of this work is to carry out a dimensional proposal for the assessment of humor appreciation. First, theoretical frames on sense of humor and particularly on humor appreciation are presented. These theoretical frames are related to the methodological characteristics of studies centered to assess humor appreciation. Then, it is justified the creation of a new scale, and it is specified the aim of assessment and the target population which this new scale is focused on. Finally, a dimensional proposal it is concretized and analyzed by a group of experts. Their judgments are presented and they are analyzed considering reviewed empirical and theoretical works. The results support some theoretical validity evidences of this dimensional proposal about humor appreciation.     

Sexual attraction: its dimensionality

The purpose of this research was to develop a new Sexual Attraction Questionnaire (SAQ) [Cuestionario de Atracción Sexual, CAS]. The goal was to determine whether sexual attraction could be represented as two different clusters (Attraction to men and Attraction to women), which would imply two negatively correlated factors or a bipolar one. Three studies were carried out with 182, 118, and 425 participants, respectively. Cluster and exploratory factor analyses were performed. The results obtained show satisfactory psychometric properties for the SAQ, the two clusters, and the two predicted negatively related factors or the bipolar factor. Results are discussed in the context of the different conceptions of sexual attraction and the fourfold typology: attracted to both sexes, to men, to women, or to neither sex.     

Stress in mothers of individuals with autistic spectrum disorders

The aim of this study was to analyze maternal stress in families of individuals with autism. We proposed a multi-factorial and global model based on the Double ABCX model of family stress (McCubbin & Patterson, 1983) in which, the factor aA (stressor) interacts with bB (social support) and cC (perception of stress or, in our study, sense of coherence, SOC) to produce the dependent factor xX (level of stress). Thirty-nine mothers with children diagnosed on Autistic Spectrum disorders completed four questionnaires relating to the factors. The data were statistically analyzed using path analysis. The results showed that the empirical data fitted the theoretically proposed model well. There existed a direct and positive relationship between stressor and stress. Social support and SOC had a direct and negative relationship to stress, and functioned as modulating variables.     

The functioning of central categories Middle Level and Sometimes in graded response scales: does the label matter?

The present study evaluates the extent to which central categories explicitly labeled as being in the middle of the other response categories, specifically Middle Level and Sometimes, function as expected according to the integer scoring system. The assumptions are tested by means of Bock's Nominal Model in two 5-response scales. Results show that the assumption of the ordering of the response categories is met for all the items. The ordering of thresholds is satisfied for all but one item with the central category Middle Level . Results are compared with those obtained when middle categories are not explicitly labeled as being in the middle of the other response categories, as in the case of Not Sure , Undecided or?     

Prejudice and attitudes of acculturation: perspectives of autochthonous and immigrants

This study is framed in a wider research on the acculturation process through a new acculturation model. The aim of this paper is to analyse the mutual prejudice between ethnic groups in contact and its relation to their preferred acculturation attitude. A questionnaire composed by various scales was given to four groups of people living in municipalities with high rate of African immigrants in Almería: Maghrebis, Sub-Saharans, Spaniards who evaluated the Maghreb out-group and Spaniards who responded on the Sub-Saharan out-group. The results obtained indicate a relation between prejudice and acculturation attitude, as the lowest scores in prejudice are hold in each group by people preferring integration , whilst the highest ones come from those who bow to exclusion/marginalisation.     

A Chilean version of the Efficient Personality Questionnaire for Adolescents

This investigation aims at adapting the test for Efficient Personality in educational contexts to Chilean reality. This instrument measures the construct efficient personality , made up of four levels of the self: strengths, requests, challenges and relationships. The original version has 58 items. In order to adapt it to our reality, 30 items were modified. The instrument was applied to a sample of 594 third and fourth secondary level students from four educational institutions of Vi?a del Mar. The new version of the instrument (23 items) presents a .85 reliability coefficient. The factorial analysis shows a structure of four basic factors which explain 50.42 % of the total variance. These factors, which are very similar those proposed in the original instrument, are named as academic self realization, social self realization, solving efficiency, and self steem. The second order factors analysis reveals a single factors structure that explains 43,28 % of the total variance, thus confirming the presence of the only factor that would correspond to the efficient personality construct presented.     

Number magnitude orients attention, but not against one’s will

Recent evidence has shown that uninformative numbers can trigger attention shifts congruent with the spatial representation of number magnitude (Fischer, Castel, Dodd, & Pratt, 2003). In the present study, three spatial-cuing experiments whose aim was to qualify the automaticity of this numbermediated orienting are described. Experiment 1 replicated the phenomenon, showing that uninformative numbers can evoke orienting in a simple detection task. In Experiment 2, target location was random, but the participants were encouraged to shift attention to the left in response to large numbers and to the right in response to small numbers. No evidence for strong automaticity was observed, since the participants’ performance was better when left-side targets were preceded by large numbers than when they were preceded by small numbers and vice versa. Experiment 3 corroborated this pattern by comparing gaze- and number-mediated cuing under conditions of real counterpredictiveness. The results indicate that unlike gaze-driven orienting, number-mediated orienting is not obligatory.     

The rhinal cortex: 'gatekeeper' of the declarative memory system

Almost all studies probing neural activity underlying the declarative memory system in humans have investigated either memory encoding or retrieval. Here, however, we suggest integrating encoding and retrieval operations into a single operation executed by the rhinal cortex. The more familiar an item is, the less rhinal processing it requires and the less vigorously it is encoded into memory. Given the anatomical position and the functional properties of the rhinal cortex, this operation fulfills an essential task: it optimally allocates limited encoding resources away from familiar information and towards novel information. We propose a rhinal processing stage that optimizes the declarative memory system by fully integrating encoding and retrieval operations into a single 'gatekeeper' operation.     

Right-left prevalence with task-irrelevant spatial codes

The present work investigated the right-left prevalence effect caused by the automatic activation of horizontal and vertical spatial codes in a task (Simon task) in which spatial information is task-irrelevant. Experiment 1 showed a horizontal Simon effect and a vertical Simon effect with a two-dimensional stimulus-response set. In Experiments 2 and 3, the right-left prevalence was obtained in two-dimensional Simon tasks with two contralateral effectors and four effectors respectively. Experiment 4 showed that horizontal coding is based on multiple spatial codes, whereas only one spatial code was formed for vertical coding. On the whole, these results support the notion that the right-left prevalence effect is a general phenomenon affecting spatial coding, and suggest that the horizontal dimension is prevalent because it is based on multiple spatial codes.     

Mother-infant relationships in baboons (Papio hamadryas): predictors of differences and discontinuities in developmental pathways

This study uses hierarchical linear regression modeling to analyze sources of variation in the developmental pathways of mother-infant relationships and to search for behavioral discontinuities. The data come from 23 mother-infant dyads of baboons (Papio hamadryas), whose interactions were recorded longitudinally during the infants' 1st year of life. The infant's sex and the mother's age and reproductive experience accounted for part of the variation observed in the developmental pathways of 11 of 20 behavioral measures analyzed; however, some of them did so only in some periods but not in others. The authors proposed that this can reflect the occurrence of reorganizations or discontinuities in the mother-infant relationship that can be related to important life events such as the mother's resumption of sexual activity.
