The emotional cost of charitable donations

Donations in support of a charitable cause can create a conflict between moral intuitions (e.g., fulfilling moral obligations and helping as many individuals in need as possible) and the cost entailed by following one's moral intuitions (e.g., spending money). The present paper investigates this conflict by putting people in a situation in which they must choose whether to help three women by giving more money or help one woman by giving less. In addition, the paper uses the attraction effect paradigm to counteract the single victim effect and reduce the conflict. Experiment 1 demonstrates that in a two-alternative context the majority of participants choose to help one woman by giving €150 instead of helping three women by giving €450. Experiment 2 replicates this finding and highlights the role of emotion regulation strategies in the management of the emotional conflict arising in the two-alternative condition. In both studies, the introduction of a third, dominated alternative reduces the conflict and makes it easier to choose the programme asking for a higher donation and helping three women. Implications for charitable donations and the role of the conflict between moral intuitions and economic costs are discussed.     

On the low-frequency vibrational spectrum of water

A new assignment is proposed for the low-frequency region of the vibrational spectrum of water, based on a comparison of the times of relevant occurring events. The time-matching is made between the dynamics of the rupture and formation time of the hydrogen bond, and the so-called bending and stretching oscillation periods of the O–H ··· O tetrahedral network. The same assignment also emerges by comparing thermal and solute concentration effects. Furthermore, a critical re-examination of the literature already existing on the subject corroborates the now proposed assignments for the modes at 60 and 170 cm^?1. These are considered to arise first from a transverse acoustic phonon with a low-frequency contribution sensitive to temperature and concentration effects, and second from external motions such as translations or restricted rotations of small water clusters inside a cage, and subjected to its potential field.     

Why do we help? World change orientation as an antecedent of prosocial action

World change orientation refers to the extent to which one individual attributes his or her prosocial action to the function of making the world a better place. In Study 1, we developed a scale to measure this world change orientation [world change scale (WCS)] and to analyze its theoretical structure as a distinctive motivational orientation. In Study 2, participants were presented with a situation of need and subsequently given an unexpected opportunity to get involved in prosocial behavior. We then tested the hypothesis that degree of involvement is predicted by WCS when the situation is framed in terms of improving the welfare of the world, but by empathic concern when the situation is framed in terms of improving the welfare of a concrete victim. The results of both studies suggest that WCS refers to a distinct motivational orientation, which affects prosocial behavior above and beyond other motives.

Adaptive n-back training does not improve fluid intelligence at the construct level: Gains on individual tests suggest that training may enhance visuospatial processing

Short-term adaptive cognitive training based on the n-back task is reported to increase scores on individual ability tests, but the key question of whether such increases generalize to the intelligence construct is not clear. Here we evaluate fluid/abstract intelligence (Gf), crystallized/verbal intelligence (Gc), working memory capacity (WMC), and attention control (ATT) using diverse measures, with equivalent versions, for estimating any changes at the construct level after training. Beginning with a sample of 169 participants, two groups of twenty-eight women each were selected and matched for their general cognitive ability scores and demographic variables. Under strict supervision in the laboratory, the training group completed an intensive adaptive training program based on the n-back task (visual, auditory, and dual versions) across twenty-four sessions distributed over twelve weeks. Results showed that this group had the expected systematic improvements in n-back performance over time; this performance systematically correlated across sessions with Gf, Gc, and WMC, but not with ATT. However, the main finding showed no significant changes in the assessed psychological constructs for the training group as compared with the control group. Nevertheless, post-hoc analyses suggested that specific tests and tasks tapping visuospatial processing might be sensitive to training.     

MMPI Supplemental Scale Performance of Mexican Americans and Level of Acculturation

Mexican American and Anglo American's performance on the Wiggins Content Scales, Harris-Lingoes subscales, and Serkownek subscales was assessed in a college student population, Level of acculturation (Mexican vs. Anglo orientation), age, and social class were statistically controlled, The results showed statistically significant differences between means of Anglo and Mexican Americans on most of the supplemental scales assessed. These differences were more numerous before scale validity criteria were applied. The number of statistically significant differences were further reduced when level of acculturation and age were statistically controlled, The results showed that level of acculturation is a highly important variable which moderates interpretation of the MMPI scale elevations we measured. Acculturation far outweighted the influence of the well established MMPI moderator variables of age and social class.     

Inferences from semifactual 'even if' conditionals

We report three experiments on semifactual conditionals such as 'even if he had worn his seatbelt he would have been injured'. Semifactuals contain a counterfactual antecedent (the presupposed fact is, he did not wear a seatbelt) and a true consequent (the fact is, he was injured). The experiments show that from the denial of the antecedent, 'he did not wear his seatbelt', reasoners do not infer the standard conclusion 'he was not injured' but instead they infer the asymmetric conclusion, 'he was injured'. From the affirmation of the consequent, 'he was injured', they do not infer the standard conclusion 'he wore his seatbelt' but instead they infer that there is no valid conclusion. The first experiment shows this pattern for 'even if' subjunctive conditionals compared to 'if' indicative conditionals, the second extends it to 'even if' subjunctive conditionals compared to 'even though' indicative concessives, and the third extends it to 'if...also/still' subjunctive conditionals. The results suggest that people think about two possibilities to understand a semifactual: the conjecture, he wore his seatbelt and he was injured, and the presupposed facts, he did not wear his seatbelt and he was injured.     

Attachment and God representations among lay Catholics, priests, and religious: a matched comparison study based on the Adult Attachment Interview

Based on the idea that believers' perceived relationships with God develop from their attachment-related experiences with primary caregivers, the authors explored the quality of such experiences and their representations among individuals who differed in likelihood of experiencing a principal attachment to God. Using the Adult Attachment Interview (AAI), they compared attachment-related experiences and representations in a group of 30 Catholic priests and religious with a matched group of lay Catholics and with the worldwide normal distribution of AAI classifications. They found an overrepresentation of secure-autonomous states regarding attachment among those more likely to experience a principal attachment to God (i.e., the priests and religious) compared with the other groups and an underrepresentation of unresolved-disorganized states in the two groups of Catholics compared with the worldwide normal distribution. Key findings also included links between secure-autonomous states regarding attachment and estimated experiences with loving or nonrejecting parents on the one hand and loving God imagery on the other. These results extend the literature on religion from an attachment perspective and support the idea that generalized working models derived from attachment experiences with parents are reflected in believers' perceptions of God.     

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."     

Experimental note on fading of briefly flashed lines

A peripheral uniform stimulus on a uniform background tends to fade when a ring enclosing the stimulus is flashed briefly, indicating that neural signals external to the stimulus such as those from the ring or those from the background tend to inhibit the onset-response or after-discharge of the stimulus. In this study, a peripheral achromatic line was flashed briefly on an achromatic background while the subject was steadily fixating on a point on the background. It was predicted that the stimulus line would fade due to background inhibition of the onset-response or afterdischarge of the stimulus. On a reference line, subjects indicated two points delimiting the part of the stimulus line which looked uniform in intensity of color. These points converged toward the center of the reference line as the luminance of the stimulus line approached that of the background. Compared to the central uniform part, the nonuniform parts near the endpoints of the stimulus line looked more faded. These results support the idea that the background surrounding a stimulus tends to inhibit the onset-response of after-discharge of the stimulus.
