Complex semantic processing in old age: does it stay or does it go?

Old adults' (N = 24) and young adults' (N = 24) speed of producing exemplars of semantic categories (i.e., semantic fluency) varying in difficulty was assessed both in a standard condition and in a "set-switching" condition where exemplars had to be produced from 2 categories in an alternating manner. "Retrieval-position function" parameters were used to assess speed of semantic access independent of nonsemantic factors. Results suggested age effects in nonsemantic components but not in semantic retrieval per se. Also, age deficits in set switching were relatively subtle. Findings are discussed with relation to issues of domain specificity of age effects as well as of the role of executive control during semantic retrieval and age differences therein.     

Happiness: When does it lead to self-indulgence and when does it lead to self-denial?

Previous research on self-gratification in children has found that happiness, compared to a neutral affective state, sometimes causes self-indulgence and sometimes causes self-denial. Review of this research led to the hypothesis that happiness leads to self-indulgence when children have no reason to believe that excessive self-gratification is morally wrong but that happiness promotes selfdenial when children fear that excessive self-gratification would violate a moral rule. In the present study, children were first placed in either a happy or neutral mood. They were then given an opportunity to help themselves freely to a reward supply, but half the children in each affect condition were warned that excessive self-gratification would violate a moral rule whereas the other half were not. In the absence of information that excessive self-gratification would violate a moral standard, happiness produced self-indulgence, but when children were told that excessive self-gratification would be wrong, happy children denied themselves significantly more than neutral-mood children. It was suggested that happiness motivates children to try to sustain their elevated mood; the behavioral route to maintaining positive mood, however, depends on how children perceive the moral implications of their actions.     

How does it feel to act together?

This paper on the phenomenology of joint agency proposes a foray into a little explored territory at the intersection of two very active domains of research: joint action and sense of agency. I explore two ways in which our experience of joint agency may differ from our experience of individual agency. First, the mechanisms of action specification and control involved in joint action are typically more complex than those present in individual actions, since it is crucial for joint action that people coordinate their plans and actions. I discuss the implications that these coordination requirements might have for the strength of the sense of agency an agent may experience for a joint action. Second, engagement in joint action may involve a transformation of agentive identity and a partial or complete shift from a sense of self-agency to a sense of we-agency. I discuss several factors that may contribute to shaping our sense of agentive identity in joint action.     

Temporal isolation does not facilitate forward serial recall—or does it?

In numerous recent studies in short-term memory, it has been established that forward serial recall is unaffected by the temporal isolation of to-be-remembered items. These findings contradict the temporal distinctiveness view of memory, which expects items that are temporally isolated from their neighbors to be more distinct and hence remembered better. To date, isolation effects have only been found with tests that do not constrain output order, such as free recall. This article reports two experiments that, for the first time, report a temporal isolation effect with forward serial recall, using a running memory task in which the end of the list is unpredictable. The results suggest that people are able to encode and use temporal information in situations in which positional information is of little value. We conclude that the overall pattern of findings concerning temporal isolation supports models of short-term memory that postulate multidimensional representations of items.     

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.     

The Rorschach: does it have a future?

Recent evidence suggests that in spite of an increasingly critical attitude by many clinicians towards the use of projective techniques, the use of these techniques has not faltered over the years. Insofar as the Rorschach continues to be the most popular projective instrument, its scientific status is critically examined in the present paper. The problems inherent in examining an instrument which has engendered a number of quite distinct scoring systems are noted, and the conclusion is advanced that notwithstanding such problems there seems little likelihood that the Rorschach will experience any significantly diminished popularity in the future.     

Learning under stress: how does it work?

The effects of stress on learning and memory are not always clear: both facilitating and impairing influences are described in the literature. Here we propose a unifying theory, which states that stress will only facilitate learning and memory processes: (i) when stress is experienced in the context and around the time of the event that needs to be remembered, and (ii) when the hormones and transmitters released in response to stress exert their actions on the same circuits as those activated by the situation, that is, when convergence in time and space takes place. The mechanism of action of stress hormones, particularly corticosteroids, can explain how stress within the context of a learning experience induces focused attention and improves memory of relevant information.     

What is free association and what does it measure?

This paper reports the results of a study of free association in which participants were asked to produce the first two words to come to mind. The findings were used to estimate the reliability of indices of strength and set size for different types of items and to model free association as a retrieval task. When confined to first responses, reliability was generally high for both indices, particularly for words with smaller sets of associates and stronger primaries. When second responses were included, reliability declined. A second response added new but weak items to the set, and, when the primary associate was not produced on the first opportunity, it tended not to be produced on the second. Relative to when multiple responses are requested, first-response free association provides more reliable indices of the relative strength and set size for a word's strongest associates. A model of free association assuming that a strength distribution underlies each response provided a good fit to the data.     

Soul: What does it mean for Russian children?

'Soul' is one of the fundamental categories of our consciousness. What does it mean for a child? Russian children from an urban area (n = 148) were interviewed to answer this question. The data shows that children understand soul as an internal phenomenon, which is responsible for the social, emotional and moral life of a person. Children believe that the soul has primacy over the body, serves to control and guide human behaviour and performs such functions as emotions, thinking, memory and wishes. Children communicate animistic, ethical and psychological meanings to the concept of soul. Comparative data obtained in four age groups of children (5-6, 6-7, 7-8, 9-10 year olds) are discussed.     

Intentional artificial grammar learning: When does it work?

Actively searching for the rules of an artificial grammar has often been shown to produce no more knowledge than memorising exemplars without knowing that they have been generated by a grammar. The present study investigated whether this ineffectiveness of intentional learning could be overcome by removing dual task demands and providing participants with more specific instructions. The results only showed a positive effect of learning intentionally for participants specifically instructed to find out which letters are allowed to follow each other. These participants were also unaffected by a salient feature. In contrast, for participants who did not know what kind of structure to expect, intentional learning was not more effective than incidental learning and knowledge acquisition was guided by salience.     

“Nowhere does it say that in the Bible”

For lesbian women who marry in South Africa, religion is both a source of great opposition to their relationships and a tool that they can use to negotiate their belonging with family and friends, after deciding to exercise their citizenship through marriage. This article draws from qualitative research conducted in South Africa to explore the relationship between sexuality and religion in the context of legal same-sex marriage. Though religion has been previously implicated in the maintenance of oppressive regimes, such as colonialism and apartheid, it has also been one of the primary voices against such injustices. The article concludes by suggesting that lesbian women use their own understandings of religion and sexuality to actively participate in the formation of new opportunities for social, legal, and spiritual citizenship.
