What does it mean to trust blockchain technology?

This paper argues that the widespread belief that interactions between blockchains and their users are trust-free is inaccurate and misleading, since this belief not only overlooks the vital role played by trust in the lack of knowledge and control but also conceals the moral and normative relevance of relying on blockchain applications. The paper reaches this argument by providing a close philosophical examination of the concept referred to as trust in blockchain technology, clarifying the trustor group, the structure, and the normatively loaded nature of this trust relation. The paper ends by critically reflecting on two of the most promising values (decentralization and transparency) that can invite users’ trust in blockchain technology, arguing that there is a tension between the pressing values that are intended to be achieved by developers and the predicament situations caused by current blockchain implementations.     

What does it mean to be angry at yourself? Categories, appraisals, and the problem of language

According to appraisal theorists, anger involves a negative event, usually blocking a goal, caused by another person. Critics argue that other-agency is unnecessary, since people can be angry at themselves, and thus that appraisal theory is wrong about anger. In two studies, we compared anger, self-anger, shame, and guilt, and found that self-anger shared some appraisals, action tendencies, and associated emotions with anger, others with shame and guilt. Self-anger was not simply anger with a different agency appraisal. Anger, shame, and guilt almost always involved other people, but almost half of the occurrences of self-anger were solitary. We discuss the incompatibility of appraisal theories with any strict categorical view of emotions, and the inadequacy of emotion words to capture emotional experience.     

What does it take to have a positive impact on minority students' college retention?

This paper describes the Young Scholars Program (YSP), which seeks to expand the pool of African American and other underrepresented minority youth who aspire to attend college, and to help them meet entrance requirements and successfully obtain a college degree. Quarter-by-quarter data for the first two groups of YSP students entering The Ohio State University were promising. Their retention rates approximated university averages, while comparison groups showed lower levels of retention. It was concluded that the many facets of the Young Scholars Program, as well as the students' positive reputation among family members, peers, and teachers, produced strong motivation, ability, and determination to succeed.     

What can we mean by “cognition,” and does it make any sense?

Practitioners of Rational-Emotive Therapy easily identify themselves with the broad camp of cognitive behavior therapy. However, the meaning of the term cognition is often unclear. Six possible meanings are outlined: (1) mental event, (2) symbolic overt behavior, (3) symbolic covert behavior, (4) pragmatic convention, (5) unreportable behavior and (6) hypothetical construct. This paper aims to: (1) clarify what we can mean when we talk about cognition, and (2) identify which meanings keep us in the tradition of empirical science and which take us to the realm of spooks and nonsense.Hank Robb works as a private practitioner.

Tigers and teapots: what does it mean to be alive?

The Symposium entitled 'Conceptual Knowledge: Developmental, Biological, Functional and Computational Accounts' was held at the British Academy, London, UK on 24-26 June 2002. It was funded by the British Academy with support from the Novartis Foundation, and organized by Lorraine Tyler (University of Cambridge, UK) and Tim Shallice (University College London, UK).     

Stress and cytokine effects on learning: What does sex have to do with it?

Many studies have alluded to sexually dimorphic changes in behavior following stress. Although many have suggested that these changes are a function of stress-induced changes in learning and memory, there are questions regarding whether performance in those learning and memory tasks are influenced by stress-induced changes in drive more than in actual learning and memory processes. We used the classically conditioned eyeblink response (CCER) to determine whether slowed learning following stress in females can be explained by changes in unconditional response (UR) amplitude, a sign of a stress-induced shift in sensory reactivity. In addition, we had a second treatment group injected with the pro-inflammatory cytokine IL-1β to serve as an interoceptive stress condition, a physiological stressor with minimal stimulation to the animal. Replicating the work by Shors and colleagues, we found that stressed female rats had slower acquisition of the conditioned response (CR), but we also found that an IL-1β injection leads to a slowing of CR acquisition. However, in both cases, UR amplitude was lower in the treatment groups. We followed up these results by testing sensory reactivity through the acoustic startle response (ASR), where the magnitude of the ASR was marginally, but nonsignificantly, reduced by the same dose regimen of IL-1β. Together, these experiments suggest that tailshock stress and immune signaling (IL-1β) reduce sensory reactivity and the saliency of the stimuli used in the CCER, leading to slower learning in female rats.     

What does it mean to be human? How salience of the human category affects responses to intergroup harm

Two studies explore how salience of the human category influences responses to intergroup harm and how different images of humanity modify these effects. In Study 1, British participants (n = 86) contemplated acts of terrorism against their group. When the human category (versus intergroup distinctions) was salient and when the prevailing image of humanity was malevolent (versus benevolent), participants were not only more understanding of terrorism, blamed this less on religious group memberships, but also more strongly endorsed the use of extreme force by countries to defend their boarders, preserve the peace and prevent future attacks. In Study 2, British participants (n = 83) contemplated the torture of Iraqi prisoners by British soldiers. When the human category was salient and the prevailing image of humanity was malevolent, participants experienced less guilt and justified torture more. We conclude that the effects of human category salience on interpretations of intergroup harm depend on what it means to be human. When human nature is perceived negatively, thinking in terms of the human category can normalise intergroup harm regardless of whether the outgroup or the ingroup is the perpetrator. Implications for re‐categorisation approaches to conflict reduction are discussed. Copyright © 2011 John Wiley & Sons, Ltd.     

What is it to “B” a relation?

The purpose of this paper is two fold: first, I look to show Oaklander’s (The ontology of time. New York: Prometheus Books, 2004) theory of time to be false. Second, I show that the only way to salvage the B-theory is via the adopting of the causal theory of time, and allying this to Oaklander’s claim that tense is to be eliminated. I then raise some concerns with the causal theory of time. My conclusion is that, if one adopts eternalism, the unreality of time looks a better option than the B-theory.

What does it mean to belong? Interpersonal bonds and intragroup similarities as predictors of felt belonging in different types of groups

Belonging is a fundamental human need, deemed essential for optimal psychological functioning. There is, however, little consensus about how people gain feelings of belonging from social groups, with theories suggesting different antecedents depending upon how groups are conceptualised. The social identity perspective conceptualises groups as social categories and proposes that feelings of group belonging arise from perceived intragroup similarity. However, if groups are construed as interpersonal networks, feelings of belonging would be expected to arise from the quality of relationships and interactions among members. We tested these predictions using multilevel structural equation modelling of longitudinal data from 113 participants. We found that perceived intragroup similarity prospectively predicted feelings of belonging within groups perceived as social categories but not within those perceived as networks, whereas the quality of interpersonal bonds predicted feelings of belonging to both kinds of groups. We discuss the importance of distinguishing types of groups and suggest implications for research into group membership and well‐being. Copyright © 2013 John Wiley & Sons, Ltd.     

Parenting and toddler self-regulation in low-income families: What does sleep have to do with it?

Toddlerhood is a sensitive period in the development of self-regulation, a set of adaptive skills that are fundamental to mental health and partly shaped by parenting. Healthy sleep is known to be critical for self-regulation; yet, the degree to which child sleep alters interactive child–parent processes remains understudied. This study examines associations between observed parenting and toddler self-regulation, with toddler sleep as a moderator of this association. Toddlers in low-income families (N = 171) and their mothers were videotaped during free play and a self-regulation challenge task; videos were coded for mothers’ behavior and affect (free play) and toddlers’ self-regulation (challenge task). Mothers reported their child's nighttime sleep duration via questionnaire. Results revealed significant Sleep × Maternal Negative Affect and Sleep × Maternal Negative Control interactions. Children who did not experience negative parenting had good self-regulation regardless of their nighttime sleep duration. For children who did experience negative parenting, self-regulation was intact among those who obtained more nighttime sleep, but significantly poorer among children who were getting less nighttime sleep. Thus, among children who were reported to obtain less nighttime sleep, there were more robust associations between negative parenting and poorer self-regulation than among toddlers who were reported to obtain more sleep.     

What does it mean to be an ally?: The perception of allies from the perspective of people of color

Allies are frequently studied from the viewpoint of dominant group members. Three studies took a different perspective by investigating how people of color perceive both White allies and allies of color. Study 1 used content analysis of qualitative data from 80 people of color to describe eight major themes of ally perception. With samples of 182 and 195 people of color, Studies 2 and 3 employed exploratory and confirmatory factor analysis to identify two subscales, informed action and affirmation, based on the themes. Both independent and paired samples t tests showed that people of color rating a White ally versus an ally of color perceived significantly less willingness to engage racial issues. Findings are discussed in relation to existing allies research.     

Do women sometimes say no when they mean yes? The prevalence and correlates of women's token resistance to sex

We investigated whether women ever engage in token resistance to sex--saying no but meaning yes--and, if they do, what their reasons are for doing so. A questionnaire administered to 610 undergraduate women asked whether they had ever engaged in token resistance and, if so, asked them to rate the importance of 26 possible reasons. We found that 39.3% of the women had engaged in token resistance at least once. Their reasons fell into three categories: practical, inhibition-related, and manipulative reasons. Women's gender role attitudes, erotophobia-erotophilia, and other attitudes and beliefs varied as a function of their experience with token resistance and their sexual experience. We argue that, given society's sexual double standard, token resistance may be a rational behavior. It could, however, have negative consequences, including discouraging honest communication, perpetuating restrictive gender stereotypes, and--if men learn to disregard women's refusals--increasing the incidence of rape.     

What does a general factor of personality look like in unshared environmental variance?

A general factor of personality (GFP) was obtained solely from unshared environment, by deriving it from the intercorrelations of monozygotic twin differences. This GFP was compared with a GFP derived from correlations reflecting all three components of variance—genes, shared environment, and unshared environment. In two large samples of adult Australian twins, for the items of two questionnaires, the two approaches gave virtually identical GFPs. However, in a sample of adolescent Australian twins, the two GFPs were correlated but distinct.     

Did she mean to do it? Acquiring a folk theory of intentionality

The ability to both identify and explain others’ intentional acts is fundamental for successful social interaction. In two cross-sectional studies, we investigated 3- to 9-year-olds’ (n = 148) understanding of the folk concept of intentionality, using three types of intentionality measures. The relationship between this type of reasoning and false belief and interpretive mind understanding was also examined. Judgment of the appropriateness of an explanation was based on adult responses (n = 20). Overall, the results indicated that the ability to both identify and appropriately explain a range of intentional acts does not fully emerge until 7 years of age or later. The pattern of explanations revealed the gradual development of a folk concept of intentionality. Preschool- and early school-age children focused on the protagonists’ desires and actions, whereas 8- and 9-year-olds and adults were more likely to reference the protagonists’ awareness and skills.
