Age-related similarities and differences in first impressions of trustworthiness

Trust is a particularly under-studied aspect of social relationships in older age. In the current study, young (n = 35) and older adults (n = 35) completed a series of one-shot social economic trust games in which they invested real money with trustees. There were potential gains with each investment and also a risk of losing everything if the trustee was untrustworthy. The reputation and facial appearance of each trustee were manipulated to make them appear more or less trustworthy. Results revealed that young and older adults invest more money with trustees whose facial appearance and reputation indicate that they are trustworthy rather than untrustworthy. However, older adults were more likely than young to invest with trustees who had a reputation for being untrustworthy. We discuss whether age-related differences in responding to negative information may account for an age-related increase in trust, particularly when trusting someone with a reputation for being uncooperative.     

ASTROBIOLOGY AND ASTROCHRISTOLOGY

Astrochristology, as a subfield within the more comprehensive astrotheology, speculates on the implications of what astrobiology and related space sciences learn about our future space neighbors. Confirmation of the existence of extraterrestrial intelligent civilizations living on exoplanets will force Christian theologians to decide on two issues. The first issue deals with the question: should Christians expect many incarnations, one for each inhabited exoplanet; or will the single incarnation in terrestrial history suffice? The second issue deals with the question: why is there an incarnation in the first place? Does the divine presence in the historical Jesus mark a divine attempt to fix a broken creation or does it mark a divine self‐communication that would occur with or without creation's fall into sin and death? Sorting these issues out is one task for astrochristology. My own position is to affirm both a single incarnation on Earth valid for cosmic redemption from the brokenness of creation in its present state.     

EXTINCTION,NATURAL EVIL,AND THE COSMIC CROSS

Did the God of the Bible create a Darwinian world in which violence and suffering (disvalue) are the means by which the good (value) is realized? This is Christopher Southgate's insightful and dramatic formulation of the theodicy problem. In addressing this problem, the Exeter theologian rightly invokes the Theology of the Cross in its second manifestation, that is, we learn from the cross of Jesus Christ that God is present to nonhuman as well as human victims of predation and extinction. God co‐suffers with creatures in their despair, abandonment, physical suffering, and death. What I will add with more force than Southgate is this: the Easter resurrection is a prolepsis of the eschatological new creation, and it is God's new creation which retroactively determines past creation. Although this does not eliminate the theodicy question, it lessens its moral sting.     

Fromm and Habermas: Allies for Adult Education and Democracy

The legacy of the Frankfurt Institute for Social Research has been a powerful force for critically understanding social reality. Erich Fromm was one of the early and best known members of the Institute. Fromm emphasised the centrality of culture and interpersonal relations in the contruction of the psyche. The unconscious was not only the location for buried repressed matter but also for the imaginative potential of the human person. He is a forgotten and neglected contributor to the story of the Institute having been written out of this history. This retrospective of his ideas explores his work in the light of the recent work of Jürgen Habermas who is also an active but less controversial engager with the psychoanalytic tradition. The implications for adult education will be addressed. The paper outlines Fromm’s radical reinterpretation of psychoanalysis emphasising the importance of social existence as distinct from the impact of instincts; key concepts of the market, commodity fetishism and automaton conformity; The implications for adult education in the tradition of radical (Freire) and transformative learning theory (Mezirow) and addressed and make connections between Habermas and Fromm that further the project of critical theory. Both attempted in different times to identify and realise the potential of (though neither used the term) of lifelong learning as part of the process of bringing about a more just and caring society and a shared attention to the importance of having free conversations about how the emancipated life might be created and sustained.     

Gadd45b knockout mice exhibit selective deficits in hippocampus-dependent long-term memory

Growth arrest and DNA damage-inducible β (Gadd45b) has been shown to be involved in DNA demethylation and may be important for cognitive processes. Gadd45b is abnormally expressed in subjects with autism and psychosis, two disorders associated with cognitive deficits. Furthermore, several high-throughput screens have identified Gadd45b as a candidate plasticity-related gene. However, a direct demonstration of a link between Gadd45b and memory has not been established. The current studies first determined whether expression of the Gadd45 family of genes was affected by contextual fear conditioning. Gadd45b, and to a lesser extent Gadd45g, were up-regulated in the hippocampus following contextual fear conditioning, whereas Gadd45a was not. Next, Gadd45b knockout mice were tested for contextual and cued fear conditioning. Gadd45b knockout mice exhibited a significant deficit in long-term contextual fear conditioning; however, they displayed normal levels of short-term contextual fear conditioning. No differences between Gadd45b knockout and wild-type mice were observed in cued fear conditioning. Because cued fear conditioning is hippocampus independent, while contextual fear conditioning is hippocampus dependent, the current studies suggest that Gadd45b may be important for long-term hippocampus-dependent memory storage. Therefore, Gadd45b may be a novel therapeutic target for the cognitive deficits associated with many neurodevelopmental, neurological, and psychiatric disorders.     

Executive function on the Psychology Experiment Building Language tests

The measurement of executive function has a long history in clinical and experimental neuropsychology. The goal of the present report was to determine the profile of behavior across the lifespan on four computerized measures of executive function contained in the recently developed Psychology Experiment Building Language (PEBL) test battery and evaluate whether this pattern is comparable to data previously obtained with the non-PEBL versions of these tests. Participants (N = 1,223; ages, 5–89 years) completed the PEBL Trail Making Test (pTMT), the Wisconsin Card Sort Test (pWCST; Berg, Journal of General Psychology, 39, 15–22, 1948; Grant & Berg, Journal of Experimental Psychology, 38, 404–411, 1948), the Tower of London (pToL), or a time estimation task (Time-Wall). Age-related effects were found over all four tests, especially as age increased from young childhood through adulthood. For several tests and measures (including pToL and pTMT), age-related slowing was found as age increased in adulthood. Together, these findings indicate that the PEBL tests provide valid and versatile new research tools for measuring executive functions.     

Four models of the functional contribution of mirror systems

In this paper we raise three questions of clarification about Alfred Mele's fine recent book, Free Will and Luck. Our questions concern the following topics: (i) Mele's combination of ‘luck’ and ‘Frankfurt-style’ objections to libertarianism, (ii) Mele's stipulations about ‘compatibilism’ and the relation between questions about free action and questions about moral responsibility, and (iii) Mele's treatment of the Consequence Argument.     

Immigration Opposition Among U.S. Whites: General Ethnocentrism or Media Priming of Attitudes About Latinos?

General ethnocentrism seems to be a powerful antecedent of immigration opinion, typically displaying larger effects than economic concerns. News about immigration, however, may focus attention on a particular group in a given historical moment. We predict group‐specific affect, not general ethnocentrism, should most powerfully shape immigration policy opinion in the contemporary United States. We test this expectation with content analyses of news coverage, survey data from 1992 to 2008, a survey experiment, and official statistics. First, we find that mentions of Latinos in news coverage of immigration outpace mentions of other groups beginning in 1994, the year when Proposition 187, a proposal in California to end most social welfare and educational assistance to illegal immigrants, garnered significant national attention. Second, while ethnocentrism dominates economic concerns in explanations of Whites' immigration policy opinions, attitudes toward Latinos in particular account for nearly all of the impact of ethnocentrism since 1994. Finally, journalistic attention to Latino immigration roughly parallels actual rates of immigration from Latin America, suggesting the media shaping of policy opinion around this group may be driven by real‐world demographic patterns.
