Differential Effects of Mother’s and Father’s Parenting on Prosocial and Antisocial Behavior: Child Sex Moderating

The current study examined the differential effects of maternal and paternal parenting on prosocial and antisocial behavior during middle childhood, and the moderating role of child sex. Parents of 96 boys and 107 girls (mean age?=?92.42?months, SD?=?3.52) completed different questionnaires to assess parenting and child behavior. All participants were Caucasian from south of Spain. Multiple hierarchical regressions (enter method) were performed to determine significant predictors of prosocial and antisocial behavior. The results showed that maternal and paternal hostility predicted an increase of externalizing problems in boys and girls (p?<?.001 in both sex groups). As well, Warmth/Induction of both parents predicted an increase in adaptive skills in boys and girls (p?<?.001 in both sex groups). On the other hand, differential effects of fathers’ and mothers’ parenting were found: both for boys and girls, maternal inconsistency positively predicted externalizing problems and negatively adaptive skills (p?<?.001 in both sex groups) and paternal overprotection positively predicted externalizing problems and negatively adaptive skills (p?<?.05 in both sex groups). Finally, maternal coercion negatively predicted adaptive skills in boys and girls (p?<?.05 in both sex groups); however, it increased externalizing problems only in girls (p?<?.05), whereas maternal permissiveness only increased these problems in boys (p?<?.01 in both cases). The discussion highlighted the importance of considering both parents’ and children’s sex to further knowledge of parenting styles affecting children’s behaviors.     

Incidental learning of trust from eye-gaze: Effects of race and facial trustworthiness

Humans rapidly make inferences about individuals’ trustworthiness on the basis of their facial features and perceived group membership. We examine whether incidental learning about trust from shifts in gaze direction is influenced by these facial features. To do so, we examined two types of face category: the race of the face and the initial trustworthiness of the face based on physical appearance. We find that cueing of attention by eye-gaze is unaffected by race or initial levels of trust, whereas incidental learning of trust from gaze behaviour is selectively influenced. That is, learning of trust is reduced for other-race faces, as predicted by reduced abilities to identify members of other races (Experiment 1). In contrast, converging findings from an independently gathered set of data showed that the initial trustworthiness of faces did not influence learning of trust (Experiment 2). These results show that learning about the behaviour of other-race faces is poorer than for own-race faces, but that this cannot be explained by differences in the perceived trustworthiness of different groups.     

Quantity discrimination in angelfish (<Emphasis Type="Italic">Pterophyllum scalare</Emphasis>) is maintained after a 30-s retention interval in the large but not in the small number range

The ability to discriminate between sets that differ in the number of elements can be useful in different contexts and may have survival and fitness consequences. As such, numerical/quantity discrimination has been demonstrated in a diversity of animal species. In the laboratory, this ability has been analyzed, for example, using binary choice tests. Furthermore, when the different number of items first presented to the subjects are subsequently obscured, i.e., are not visible at the moment of making a choice, the task requires memory for the size of the sets. In previous work, angelfish (Pterophyllum scalare) have been found to be able to discriminate shoals differing in the number of shoal members both in the small (less than 4) and the large (4 or more) number range, and they were able to perform well even when a short memory retention interval (2–15 s) was imposed. In the current study, we increased the retention interval to 30 s during which the shoals to choose between were obscured, and investigated whether angelfish could show preference for the larger shoal they saw before this interval. Subjects were faced with a discrimination between numerically small shoals (≤4 fish) and also between numerically large (≥4 fish) shoals of conspecifics. We found angelfish not to be able to remember the location of larger versus smaller shoals in the small number range, but to exhibit significant memory for the larger shoal in the large number range as long as the ratio between these shoals was at least 2:1. These results, together with prior findings, suggest the existence of two separate quantity estimation systems, the object file system for small number of items that does not work with the longer retention interval and the analogue magnitude system for larger number of items that does.     

Is Stephen Hawking Building Walls? A Cosmic Dilemma

Stephen Hawking leaves us with the ancient hospitality dilemma: do we welcome ETIs as immigrants or build a wall to keep them away?     

Moved by words: Affective ratings for a set of 2,266 Spanish words in five discrete emotion categories

The two main theoretical accounts of the human affective space are the dimensional perspective and the discrete-emotion approach. In recent years, several affective norms have been developed from a dimensional perspective, including ratings for valence and arousal. In contrast, the number of published datasets relying on the discrete-emotion approach is much lower. There is a need to fill this gap, considering that discrete emotions have an effect on word processing above and beyond those of valence and arousal. In the present study, we present ratings from 1,380 participants for a set of 2,266 Spanish words in five discrete emotion categories: happiness, anger, fear, disgust, and sadness. This will be the largest dataset published to date containing ratings for discrete emotions. We also present, for the first time, a fine-grained analysis of the distribution of words into the five emotion categories. This analysis reveals that happiness words are the most consistently related to a single, discrete emotion category. In contrast, there is a tendency for many negative words to belong to more than one discrete emotion. The only exception is disgust words, which overlap least with the other negative emotions. Normative valence and arousal data already exist for all of the words included in this corpus. Thus, the present database will allow researchers to design studies to contrast the predictions of the two most influential theoretical perspectives in this field. These studies will undoubtedly contribute to a deeper understanding of the effects of emotion on word processing.     

Invariance of the “NEO-PI-R” factor structure across exploratory and confirmatory factor analyses

Confirmatory factor analyses (CFA) carried out in the last decades to test the Five-factor simple structure have generally obtained negative results. McCrae, Zonderman, Costa, Bond, and Paunonen (1996) suggested that CFA limitations were the main cause of such negative results. They also claim that Procrustes Orthogonal rotation method is an adequate procedure to test the replicability of the Five-factor structure. The aim of the present paper is twofold: (A) comparing several Exploratory factor procedures (including the Procrustes rotation) to test what is the most appropriate one to analyse the replicability of the Five-factor structure, and (B) replicating the CFA results of the McCrae et al.’s study with a larger number of subjects. The normative American (N = 1000), and Spanish (2000) standardization samples of the NEO-PI-R, together with an independent university sample (N = 948) were analysed. Results were replicated in the three samples, and suggest that: (1) structural properties of the Five-factor model, as measured by the NEO-PI-R, are invariant irrespective of the Exploratory factor procedure used, and (2) when CFA limitations are surpassed, the Five-factor structure is supported.     

Inventory of Overburden in Alzheimer's Patient Family Caregivers with no Specialized Training

Background/Objective: Alzheimer-type dementia is one of the most frequent causes of dependence in an aging population, which combines with a considerable demand for care. Furthermore, when the caregiver is a family member or person without specialized training, such care impacts on that person's health. The Inventory of Overburden in Alzheimer's Patient Family Caregivers with no Specialized Training (IPSO-CA24) was designed to find out the needs of these caregivers and evaluate the caregiver's burden or distress. Method: The psychometric properties of the questionnaire were analyzed (in a reliability analysis, exploratory factor analysis and confirmatory analysis) based on the responses of 255 caregivers. Results: The factor analyses showed a six-factor structure (Reaction to diagnosis, Physical health, Psychological symptomatology (caretaker), Behavioral symptomatology (patient), Knowledge of the illness, and Level of dependence) explaining 66.52% of the total variance with a reliability of .75 to .93. Support was also found for its convergent validity. Conclusions: The IPSO-CA24 responds to the need for an instrument enabling multidimensional evaluation of the burden on the family caregiver without specialized training.     

Indirect Effects of Functional Communication Training on Non-Targeted Disruptive Behavior

The purpose of this study was to evaluate the effects of functional communication training (FCT) on the occurrence of non-targeted disruptive behavior. The 10 participants were preschool-aged children with developmental disabilities who engaged in both destructive (property destruction, aggression, self-injury) and disruptive (hand flapping, spinning in circles, shrill laughter, screaming, crying) behaviors. Only destructive behavior was targeted for the functional analyses and FCT, but data were also collected on disruptive behaviors. All procedures were conducted in the participants’ homes by their mothers with investigator coaching. Phase 1 consisted of conducting a functional analysis within a multielement design. Phase 2 consisted of conducting FCT with demand fading and repeated extinction baselines within a reversal design. Single-case data are provided for 3 participants, and summary data are provided for all 10 participants. Results of phase 1 showed that all participants’ destructive and disruptive behavior was maintained, at least in part, by negative reinforcement. Results of phase 2 showed that both destructive behavior and non-targeted disruptive behavior occurred at lower levels during FCT when compared to the functional analysis demand condition and baseline conditions, suggesting that FCT was effective in decreasing both target destructive behavior and non-targeted disruptive behaviors.
