People in last place were more than 4 times more likely to renege from queues, altogether giving up on the service for which they were queuing; this behavior is partially explained by the inability to make a downward social comparison

Abstract: This paper investigates whether people exhibit last place aversion in queues and its implications for their experiences and behaviors in service environments. An observational analysis of customers queuing at a grocery store, and three online field experiments in which participants waited in virtual queues, revealed that waiting in last place diminishes wait satisfaction while increasing the probabilities of switching and abandoning queues. After controlling for other factors, people in last place were more than twice as likely to switch queues, which increased the duration of their wait and diminished their overall satisfaction. Moreover, people in last place were more than four times more likely to renege from queues, altogether giving up on the service for which they were queuing. The results indicate that this behavior is partially explained by the inability to make a downward social comparison; namely, when no one is behind a queuing individual, that person is less certain that continuing to wait is worthwhile. Furthermore, this paper provides evidence that queue transparency is an effective service design lever that managers can use to reduce the deleterious effects of last place aversion in queues. When people can't see that they're in last place, the behavioral effects of last place aversion are nullified, and when they can see that they're not in last place, the tendency to renege is greatly diminished.

Lack of erotic thoughts, fear & desire to have a baby are the main predictors of the level of sexual desire. Energy-fatigue, depression, premature ejaculation severity, sexual distress, compatibility, subjective sexual response, & sexual conservatism had a weaker effect on sexual desire

Abstract

Background: The literature lacks studies of the male sex drive. Most existing studies have focused on hypoactive sexual desire disorder in coupled heterosexual men, highlighting some of the main related biological, psychological, and social factors.

Aim: To evaluate the role of selected psychological and social variables affecting male sexual desire such as quality of life, sexual function, distress, satisfaction, psychological symptoms, emotions, alexithymia, couple adjustment, sexism, cognitive schemas activated in a sexual context, sexual dysfunctional beliefs, and different classes of cognitions triggered during sexual activity about failure anticipation, erection concerns, age- and body-related thoughts, erotic fantasies, and negative attitudes toward sexuality.

Methods: A wide self-administered survey used snowball sampling to reach 298 heterosexual Italian men (age = 32.66 ± 11.52 years) from the general population.

Outcomes: 13 questionnaires exploring psychological and social elements involved in sexual response were administrated: International Index of Erectile Function, Short Form 36 for Quality of Life, Beck Depression Inventory–II, Symptom Check List–90–Revised, Toronto Alexithymia Scale, Premature Ejaculation Severity Index, Sexual Distress Scale, Sexual Satisfaction Scale, Dyadic Adjustment Scale, Ambivalent Sexism Inventory, Sexual Modes Questionnaire, Sexual Dysfunctional Belief Questionnaire, and Questionnaire of Cognitive Schema Activation in Sexual Context.

Results: Results showed lack of erotic thoughts (β = −0.328), fear (β = −0.259) and desire to have a baby (β = −0.259) as the main predictors of the level of sexual desire in this group. Energy-fatigue, depression, premature ejaculation severity, sexual distress, compatibility, subjective sexual response, and sexual conservatism had a weaker effect on sexual desire. Sexual functioning (13.80%), emotional response (12.70%), dysfunctional sexual beliefs (12.10%), and negative automatic thoughts (12.00%) had more variable effects on sexual drive.

Clinical Translation: Analyzed variables could represent important factors that should be considered in the assessment of desire concerns and discussed in therapy.

Strengths and Limitations: The strength of this study is the analysis of novel psychological and social factors on male sexual desire. Recruitment and sample size do not allow generalization of the results, but some crucial points for future research and clinical practice are discussed.

Conclusion: Our findings showed that male sexual desire could be affected by many psychological and social elements. Other factors remain to be explored, in their direct and interactive effects, aiming to better explain male sexual desire functioning.

As in previous findings, the blind have lower REMs density. However the ability of dream recall in congenitally blind and sighted controls is identical. In both groups visual dream recall is associated with an increase in REM bursts and density

Rapid Eye Movements (REMs) and visual dream recall in both congenitally blind and sighted subjects. Helder Bértolo et al. Proceedings of SPIE, 2017 https://www.spiedigitallibrary.org/conference-proceedings-of-spie on 10/9/2017 (http://eprints.ucm.es/45054/1/Antona_Proceedings%20of%20SPIE-2017.pdf)

ABSTRACT: Our objective was to evaluate rapid eye movements (REMs) associated with visual dream recall in sighted subjects and congenital blind.

During two consecutive nights polysomnographic recordings were performed at subjects home. REMs were detected by visual inspection on both EOG channels (EOG-H, EOG-V) and further classified as occurring isolated or in bursts. Dream recall was defined by the existence of a dream report. The two groups were compared using t-test and also the two-way ANOVA and a post-hoc Fisher test (for the features diagnosis (blind vs. sighted) and dream recall (yes or no) as a function of time).

The average of REM awakenings per subject and the recall ability were identical in both groups. CB had a lower REM density than CS; the same applied to REM bursts and isolated eye movements. In the two-way ANOVA, REM bursts and REM density were significantly different for positive dream recall, mainly for the CB group and for diagnosis; furthermore for both features significant results were obtained for the interaction of time, recall and diagnosis; the interaction of recall and time was however, stronger.

In line with previous findings the data show that blind have lower REMs density. However the ability of dream recall in congenitally blind and sighted controls is identical. In both groups visual dream recall is associated with an increase in REM bursts and density. REM bursts also show differences in the temporal profile. REM visual dream recall is associated with increased REMs activity.
