Higher and Lower Pleasures – Doubts on Justification

According to the discontinuity view we can have a (lower) pleasure which, no matter how often a certain unit of it is added to itself, cannot become greater in value than a unit of another (higher) pleasure. All recent adherents of this view seem to rely basically on the same sort of reasoning which is referred to here as the preference test. This article presents three arguments, each of which indicates that the inference from the preference test to the discontinuity view is not conclusive.     

Representation of subjective preferences under ambiguity

The objective of this paper is to show how potentially incomplete preferences of a decision maker (DM) on acts can be modelled formally in a subjective ambiguity perspective. We identify acts as functions from a state space Ω to bounded support (finitely additive) probabilities over a set X of prizes. Then, we characterize preferences over equibounded acts a which have a numerical representation by the family of functionals , where u is a cardinal utility on X (representing the risk attitude of the DM) and Π is a unique pointwise closed convex set of probabilities on all events in Ω (representing the ambiguity perceived by the DM). To this end, in addition to the usual independence and continuity assumptions, we add completeness and dominance for preferences restricted to constant acts; moreover, we consider two other properties (subjective monotonicity and coherence) related with the preferences of a DM who is not able, owing to his partial knowledge, to evaluate any event in Ω.     

Reducing indices of unhappiness among individuals with profound multiple disabilities during therapeutic exercise routines.

A program was developed to reduce indices of unhappiness that accompanied therapeutic exercise routines among people with profound multiple disabilities. Indices of unhappiness were recorded, using an observation system that had been validated through previous research involving happiness-related variables, while support personnel conducted exercises with 3 participants. A multicomponent program was then implemented that involved presenting highly preferred stimuli before, during, and after each exercise session. Results indicated that the program was accompanied by reduced indices of unhappiness for each participant relative to the traditional method of conducting the exercises, although changes in the preferred stimuli used with 1 participant were required before consistent reductions occurred. Results are discussed regarding the importance of reducing unhappiness indices as a means of enhancing aspects of the daily quality of life for people with profound multiple disabilities. Areas for future research are also discussed, focusing on expanding the unhappiness-reduction procedures to other routine events that may occasion indices of unhappiness.     

Is variability in mate choice similar for intelligence and personality traits? Testing a hypothesis about the evolutionary genetics of personality

This study tests the hypothesis presented by Penke, Denissen, and Miller (2007a) that condition-dependent traits, including intelligence, attractiveness, and health, are universally and uniformly preferred as characteristics in a mate relative to traits that are less indicative of condition, including personality traits. We analyzed between-culture mean standard deviations of preference ratings and rankings provided by nearly 10,000 people in 37 cultures for 18 characteristics in a potential mate. Contrary to the hypothesis, preferences for traits indicating agreeableness and conscientiousness were not more variable than preferences for intelligence, and preferences for traits indicating low neuroticism were more uniform than preferences for intelligence. Discussion addresses implications of these results for hypotheses about the evolutionary genetics of intelligence and personality.     

It is not all about the Benjamins: Understanding preferences for mates with resources

We contend that preferences for mates with resources or money might be calibrated on where a potential mate gets her/his money. In three studies (N = 668) we examined the nature of individuals’ preferences for mates who have resources or money. Both sexes preferred a long-term mate who has earned her/his money over other sources. In particular, women preferred mates who earned their money over other potential means of getting resources (i.e., inheritance, embezzlement, and windfall). Women maintained a high level of interest in mates who earned their money regardless of duration of the mateship whereas men became less interested in a mate who earned her money in the context of short-term relationships. Overall, the sexes preferred a mate who earned their money more strongly in the long-term than the short-term context. Results are discussed from evolutionary and sociocultural models of mate preferences.     

Liking and identifying emotionally expressive music: age and gender differences

Adults and children 5, 8, and 11 years of age listened to short excerpts of unfamiliar music that sounded happy, scary, peaceful, or sad. Listeners initially rated how much they liked each excerpt. They subsequently made a forced-choice judgment about the emotion that each excerpt conveyed. Identification accuracy was higher for young girls than for young boys, but both genders reached adult-like levels by age 11. High-arousal emotions (happiness and fear) were better identified than low-arousal emotions (peacefulness and sadness), and this advantage was exaggerated among younger children. Whereas children of all ages preferred excerpts depicting high-arousal emotions, adults favored excerpts depicting positive emotions (happiness and peacefulness). A preference for positive emotions over negative emotions was also evident among females of all ages. As identification accuracy improved, liking for positively valenced music increased among 5- and 8-year-olds but decreased among 11-year-olds.     

Personality accounts for stable preferences and expectations across a range of simple games

Behaviour on even simple experimental games shows considerable individual differences, but previous attempts to link these preferences to stable personality traits have had mixed results. Here we address three limitations of earlier studies, namely: (1) uncertainties concerning the reliability of preferences; (2) use of personality instruments with limited cross-study comparability; and (3) confounds where more than one psychological motive can lead to a particular choice. Sixty-seven participants completed 12 distinct real-money games twice over a two-week interval along with 6 measures concerning their expectations about other players’ choices. Personality was measured using the full NEO-PI-R. Choices were highly stable across time (r = .84). Moreover, choices on the 12 games and 6 expectations reflected a single underlying dimension of “prosocial orientation”, measuring concern for the payoffs received by other players. Scores on the prosocial orientation dimension were related to personality, with openness, (low) neuroticism, and (low) extraversion retained as significant predictors.     

Work and home boundary violations during the COVID-19 pandemic: The role of segmentation preferences and unfinished tasks

During the COVID-19 pandemic, an unprecedented number of employees faced the challenges of telework. However, the current literature has a limited understanding of the implications of employees' obligated home-based telework and their satisfaction with the work and home domains. We use boundary theory to examine work and home boundary violations in relation to satisfaction with domain investment in two daily diary studies, examining both domain-specific and cross-domain effects. In addition, we examine the moderating role of segmentation preferences in both studies and investigate the mediating role of work- and home-related unfinished tasks in Study 2. Both studies provide empirical evidence of the domain-specific relationship between boundary violations and domain satisfaction and provide limited support for cross-domain effects. Neither study finds support for the notion that segmentation preferences moderate the relationship between boundary violations and domain satisfaction. Finally, the results of Study 2 highlight the importance of unfinished tasks in the relationship between boundary violations and domain satisfaction. Specifically, work and home boundary violations relate to an increase in unfinished tasks in both domains. Finally, the indirect effects suggest that home-related unfinished tasks may be detrimental to satisfaction in both domains, while work-related unfinished tasks may be detrimental for work-related, but not home-related, satisfaction.     

Intermanual differences on neuropsychological motor tasks in a Japanese university student sample

We explored the intermanual difference scores of 128 Japanese university students for five typical neuropsychological motor tasks (grip strength, finger tapping, two versions of the grooved pegboard, and the dot‐filling test) and examined the relation between hand preference and intermanual difference in motor proficiency. Using the Edinburgh Handedness Inventory, 18 and 110 participants were identified as left‐ and right‐handed, respectively. Although the right hand performed better than the left for right‐handed participants, and vice versa, in all five tasks, the degree of intermanual difference varied between tasks. A discriminant function analysis using the laterality quotients of the five motor tasks as independent variables indicated that hand preference was predictable from the task performances with an accuracy of 90% or more. The dot‐filling test and finger tapping had stronger canonical loadings than the other tasks.     

Acculturation Preference Profiles of Spaniards and Romanian Immigrants: The Role of Prejudice and Public and Private Acculturation Areas

The main goal of this study was to identify acculturation preference profiles using cluster analysis in public and private areas of culture in the host and immigrant populations, and to find out the relationship between these profiles and prejudice levels. Four hundred and ninety-nine Spaniards and 500 Romanians participated in a survey. The sampling of Spaniards was multistage random and the sampling of Romanians was by quota. The results confirm our predictions. Romanians who are less prejudiced against Spaniards prefer assimilation in public areas and integration in private areas. Romanians who are more prejudiced against Spaniards prefer integration in public areas and separation in private areas. Spaniards who are less prejudiced against Romanians prefer integration in both public and private areas. Spaniards who are more prejudiced against Romanians prefer assimilation in both areas.
