The behavior system for sexual learning. Michael Domjan, Germán Gutiérrez. Behavioural Processes, Volume 162, May 2019, Pages 184-196, https://doi.org/10.1016/j.beproc.2019.01.013
Highlights
• Reviews the current status of the behavior system for sexual learning.
• In addition to reviewing research with quail (which was the focus of prior paper), in this treatment research with rats is also incorporated into the characterization of the behavior system.
• Unlike prior papers which dealt primarily with sexual learning in males, in this review we also discuss in detail sexual learning in females.
• For the first time the characterization of the sexual learning system includes detailed information on how learning facilitates fertilization and reproductive success.
• Although much progress has been made in characterizing the sexual learning system, we include an extensive section discussing areas for future research.
• A new perspective on how sexual learning can contribute to evolutionary change is included.
Abstract: In this paper we review and update evidence relevant to formulating a behavior system for sexual learning. We emphasize behavioral rather than neurobiological evidence and mechanisms. Our analysis focuses on three types of responses or response modes: general search, focal search, and consummatory or copulatory behavior. We consider how these response modes are influenced by three categories of stimuli: spatially distributed contextual cues, arbitrary localized stimuli, and species-typical cues provided by the sexual partner. We characterize behavior control by these types of stimuli before and after various Pavlovian conditioning procedures in which the unconditioned stimulus is provided by copulation with a sexual partner. The results document extensive Pavlovian modifications of sexual behavior. These conditioning effects reflect new conditioned responses that come to be elicited by various categories of stimuli. In addition, the conditioning of contextual cues and localized stimuli facilitate sexual responding to species-typical cues. Thus, learning experiences enhance how the species-typical cues of a sexual partner stimulate sexual behavior. These modulatory conditioning effects not only produce significant behavioral changes but also increase rates of fertilization of eggs and numbers of offspring produced. These latter findings suggest that sexual learning can lead to differential reproductive success, which in turn can contribute to evolutionary change.

Bottlenose dolphins do not behave prosocially in an instrumental helping task: Ignore their partners and did not help them reach a preferred toy
Bottlenose dolphins do not behave prosocially in an instrumental helping task. Ana Pérez-Manrique, Antoni Gomila. Behavioural Processes, Apr 24 2019. https://doi.org/10.1016/j.beproc.2019.04.014
Highlights
• A group of captive bottlenose dolphins were tested in an instrumental helping task
• Bottlenose dolphins did not behave prosocially in this task
• Dolphins ignore their partners and did not help them reach a preferred toy
Abstract: Although bottlenose dolphins (Tursiops truncatus) are known for being a highly social species that live in complex societies that rely on coalition formation and cooperative behaviours, experimental studies on prosocial behaviour in this species are scarce. Helping others reach their goals (instrumental helping) is considered as an example of prosocial behaviour. Thus, in this pilot study, we examined whether a group of five captive bottlenose dolphins would behave prosocially in an instrumental helping task. Dolphins were given the opportunity to share tokens that allow their partners to obtain a preferred toy. Dolphins were tested in their free time and they could choose to share the tokens or do nothing. None of the dolphins shared the tokens, instead, they preferred to play with them, ignoring their partners. They did transfer the tokens to other sides of the pool but out of the reach of their partners. Therefore, this group of dolphins did not spontaneously help their partners in this task, showing no preference for other-regarding behaviour in this context.

Individual outcomes of irrational thinking, including belief in the paranormal and non-scientific thinking: althought it diminishes financial profitability, the component of belief in the paranormal improves the psychological state
Is irrational thinking associated with lower earnings and happiness? Shoko Yamane, Hiroyasu Yoneda, Yoshiro Tsutsui. Mind & Society, Apr 23 2019. https://link.springer.com/article/10.1007/s11299-019-00213-4
Abstract: This study investigates the individual outcomes of irrational thinking, including belief in the paranormal and non-scientific thinking. These modes of thinking are identified through factor analysis of eleven questions asked in a large-scale survey conducted in Japan in 2008. Income and happiness are used as measures of individual performance. We propose two hypotheses. Previous studies in finance lead us to consider Hypothesis 1 that both higher belief in the paranormal and non-scientific thinking are associated with lower income. Literature on the association between religion, the paranormal, and happiness suggest Hypothesis 2 that higher belief in the paranormal is associated with greater happiness, while higher non-scientific thinking is associated with greater unhappiness. To examine these hypotheses, we regress income and happiness on belief in the paranormal and non-scientific thinking with appropriate control variables. We employ the Mincer-type wage function as the income equation. Income, sex, and age are controlled in the happiness equation. Analysis supports both hypotheses, which highlights the complex features of irrationality. Although irrationality results in diminishing financial profitability, the component of belief in the paranormal improves the psychological state.

1 Introduction
This study aims to discover whether rational thinking is necessary for better human performance (income and happiness), using Japanese data. Rationality is the essen-tial assumption of traditional economics, meaning that based on facts, agents think and act logically, in order to achieve their goals, given their constraints.1
The consequences of irrationality, i.e., violating requirements of logical rationality, have been studied in the field of behavioral finance. Shumway and Wu (2006) empirically analyzed the Shanghai stock exchange and found that traders who display the disposition effect, i.e., exhibit a greater propensity to realize gains compared to losses, earn less profits. Barber and Odean (2001) showed that men transact too often because of their overconfidence, leading to low profitability. These empirical results are consistent with the hypothesis that irrationality reduces profitability. However, there exists the possibility that irrationality works in an opposite direction. DeLong et al. (1990) theoretically analyzed the efficiency of a financial market that consists of a mix of rational and irrational agents and showed that this market can be inefficient if irrational agents comprise a substantial fraction of market participants.2 Thus, if irrational agents dominate, behaving irrationally in concordance with many other irrational agents can be profitable.
On the contrary, it is not known how irrationality is associated with happiness.3 In this study, we measure individuals’ degree of logical thinking by assessing the extent to which they believe in science and paranormal phenomena. Although these may seem to be two sides of the same coin, they essentially have different characteristics, as is demonstrated in Sect. 2.4 Many studies reported that those individuals who are deeply religious are happier (Koenig et al. 2001). Wills (2009) reported that higher satisfaction with spirituality and religiosity brings about significantly higher well-being (see also Cohen 2002), suggesting that those who believe in paranormal phenomena may be happier, since belief in religion overlaps, in part, belief in paranormal phenomena (see Sect. 2.2).
In order to address the question as to whether irrational thinking leads to lower profitability measured by income and happiness, we conducted an original survey in Japan. Of all the questions, 11 deal with paranormal phenomena and scientific facts. Using factor analysis, we extract two factors, namely, belief in paranormality and non-scientific thinking. We analyzed the association between these two factors and individual outcomes in terms of income and happiness.1 For more discussions on rationality, see Wilkinson (2008).2 The authors assume that rational agents are risk averse, which restricts them from carrying out unlimited arbitrage.3 Nevertheless, how happiness depends on various attributes and traits has been extensively investigated (see, e.g., Frey and Stutzer 2002). For example, based on a dictator game experiment, Konow and Earley (2008) found that more generous people report greater happiness.4 Lindeman and Aarnio (2007) offered some support for this; they reported that superstition is well predicted by ontological confusion, but not by analytical thinking.

When individuals feel similar to their future self, they are more likely to delay present gratification & make plans for the long run; greater perceived similarity to the future self is linearly associated with greater life satisfaction 10 y later
Identity Over Time: Perceived Similarity Between Selves Predicts Well-Being 10 Years Later. Joseph S. Reiff, Hal E. Hershfield, Jordi Quoidbach. Social Psychological and Personality Science, April 23, 2019. https://doi.org/10.1177/1948550619843931
Abstract: When individuals feel similar to their future self, they are more likely to delay present gratification and make plans for the long run. But do these feelings of similarity actually correspond with heightened well-being for the future self? Theoretically, making patient decisions in the present could lead to a future self who is better off and thus more satisfied. Alternatively, perceived overlap with the future self could cause people to continually deny themselves pleasures in the present, diminishing satisfaction over time. To adjudicate between these possibilities, we use a 10-year longitudinal data set (N = 4,963) to estimate how thoughts about one’s future self in an initial survey predict life satisfaction 10 years later. Controlling for initial life satisfaction, greater perceived similarity to the future self is linearly associated with greater life satisfaction 10 years after the original prediction, a finding that is robust to a number of alternative analyses.

7 years after passage of a Renewable Portfolio program, the required renewable share of generation is 1.8 pct higher & average retail electricity prices are 1.3 cent/kWh, 11% higher (12 years after, 4.2 pct higher, & costs are 17% higher)
Do Renewable Portfolio Standards Deliver? Michael Greenstone, Richard McDowell, Ishan Nath. University of Chicago, Becker Friedman Institute for Economics Working Paper No. 2019-62. Apr 19 2019. https://ssrn.com/abstract=3374942
Renewable Portfolio Standards (RPS) are the largest and perhaps most popular climate policy in the US, having been enacted by 29 states and the District of Columbia. Using the most comprehensive panel data set ever compiled on program characteristics and key outcomes, we compare states that did and did not adopt RPS policies, exploiting the substantial differences in timing of adoption. The estimates indicate that 7 years after passage of an RPS program, the required renewable share of generation is 1.8 percentage points higher and average retail electricity prices are 1.3 cents per kWh, or 11% higher; the comparable figures for 12 years after adoption are a 4.2 percentage point increase in renewables’ share and a price increase of 2.0 cents per kWh or 17%. These cost estimates significantly exceed the marginal operational costs of renewables and likely reflect costs that renewables impose on the generation system, including those associated with their intermittency, higher transmission costs, and any stranded asset costs assigned to ratepayers. The estimated reduction in carbon emissions is imprecise, but, together with the price results, indicates that the cost per metric ton of CO2 abated exceeds $130 in all specifications and ranges up to $460, making it least several times larger than conventional estimates of the social cost of carbon. These results do not rule out the possibility that RPS policies could dynamically reduce the cost of abatement in the future by causing improvements in renewable technology.

* Renewable energy mandates reduce CO2 emissions at the astounding price of between $130 to $460 per ton. This is like adding between $54.60 to $193.20 to the price of a barrel of oil.
* The cost of reducing CO2 emissions via renewable mandates is much more expensive than the so-called “social cost of carbon.” Enviro groups claim that social cost of carbon is about $40 per ton.
* Renewable energy mandates in the 29 states have reduced CO2 emissions by a mere 95 – 175 MILLION metric tons of CO2 after seven years. Annual manmade emissions of CO2 are about 53.5 billion tons per year.

The relations between social network site use and Big Five traits were weak or nil; the moderator effects of study country and participant gender were mixed
Social network site use and Big Five personality traits: A meta-analysis. Chiungjung Huang. Computers in Human Behavior, Volume 97, August 2019, Pages 280-290. https://doi.org/10.1016/j.chb.2019.03.009
Highlights
• The relations between social network site use and Big Five traits were weak or nil.
• The moderator effects of study country and participant gender were mixed.
• Effects of the rest of moderators were not supported.
Abstract: This meta-analysis summarized the relations between social network site use and neuroticism, extraversion, openness, agreeableness and conscientiousness. Sixty-one articles comprising 67 independent samples (N = 22,899 participants) were identified. The overall correlations of social network site use with neuroticism (avg-r= 0.08) and extraversion (avg-r= 0.09) were about positively small, while conscientiousness had a negative and quite small correlation with social network site use with avg-r = −0.04. Openness and agreeableness were not significantly correlated with social network site use with avg-r = −0.01. The effects of most moderators, including publication outlet, site participants spent time, scale of time spent, indicator of social network site use, Big Five measure, and participant age were not significant. In contrast, the effects of country where the study was conducted and participant gender were mixed.
