Differential course of executive control changes during normal aging

Normal aging has been associated with executive control deficits, but it is as yet unclear whether different executive subprocesses are differentially affected during the course of aging. The present study aimed to investigate age effects on a range of executive control subcomponents. Four consecutive age groups (20-30 years, 31-45 years, 46-60 years, 61-75 years), matched on present state IQ and mood, were compared on tasks of strategic memory processing, verbal fluency, reasoning, inhibition, task management, and self-rating of executive abilities. Deficits concerning the suppression of habitual and experimentally induced prepotent response tendencies and the ability to efficiently divide attention were observed in subjects over 60 years of age compared to the younger groups, while memory, verbal fluency, and reasoning were largely unaffected. Results suggest a sharp decline of executive function after age 60 and a differential course of different executive subcomponents across aging, adding further support to a multi-dimensional model of executive function.     

Masked prime stimuli can bias “free” choices between response alternatives

Stimuli presented below the threshold of awareness can systematically influence choice responses determined by the instructed stimulus-response (S-R) mapping (task set). In this study, we investigated whether such stimuli will also bias a free choice between two response alternatives under conditions in which this choice subjectively appears to be internally generated and free. Participants had to respond to targets preceded by masked arrow primes. Left-pointing and right-pointing arrow targets required left or right responses, whereas randomly interspersed “free-choice” targets indicated that the participants were free to choose either response. Although masked primes could not be consciously discriminated, they systematically affected not only performance to arrow targets, but also the free choice between response alternatives. This demonstrates that apparently “free” choices are not immune to nonconsciously triggered biases. However, in blocks in which no specific S-R mapping was imposed, masked primes did not affect free-choice performance, indicating that these effects are not automatic but are determined by currently active task sets.     

Relative truth and the first person

In recent work on context-dependency, it has been argued that certain types of sentences give rise to a notion of relative truth. In particular, sentences containing predicates of personal taste and moral or aesthetic evaluation as well as epistemic modals are held to express a proposition (relative to a context of use) which is true or false not only relative to a world of evaluation, but other parameters as well, such as standards of taste or knowledge or an agent. I will argue that the sentences that apparently give rise to relative truth should be understood by relating them in a certain way to the first person. More precisely, such sentences express what I will call ‘first-person-based genericity’, a form of generalization that is based on an essential first-person application of the predicate. The account differs from standard relative truth account in crucial respects: it is not the truth of the proposition expressed that is relative to the first person; the proposition expressed by a sentence with a predicate of taste rather has absolute truth conditions. Instead it is the propositional content itself that requires a first-personal cognitive access whenever it is entertained. This account, I will argue, avoids a range of problems that standard relative truth theories of the sentences in question face and explains a number of further peculiarities that such sentences display.     

The meaning and legacy of the Reformation in a global perspective

When reviewing the non‐European perspectives of Lutheran theology presented in the contributions of this issue of Dialog, it is easy to recognize a dominant, unifying theme and a common task in a confrontation with the new Pentecostal churches. It then makes sense to refer to the two central themes and tasks of Lutheran theology mentioned in this volume: the development of a Lutheran pneumatology in contrast to the Pentecostal/charismatic movements; and an interpretation of the Lutheran doctrine of justification that concentrates on how the pure grace and love of God can be witnessed in good works. As a future focal point of Lutheran theology, the contributions from non‐European Lutheran Christianity presented here show that the connection between the theology of the cross as a central element of the grammar of Lutheran Christianity and the dialectics of law and gospel for the interpretation of the salutary efficacy and experienceable nature of the Spirit requires further reflection.     

Propositional Attitudes Without Propositions

The most common account of attitude reports is the relational analysis according towhich an attitude verb taking that-clause complements expresses a two-placerelation between agents and propositions and the that-clause acts as an expressionwhose function is to provide the propositional argument. I will argue that a closerexamination of a broader range of linguistic facts raises serious problems for thisanalysis and instead favours a Russellian `multiple relations analysis' (which hasgenerally been discarded because of its apparent obvious linguistic implausibility).The resulting account can be given independent philosophical motivations within anintentionalist view of truth and predication.     

Nominalizing Quantifiers

Quantified expressions in natural language generally are taken to act like quantifiers in logic, which either range over entities that need to satisfy or not satisfy the predicate in order for the sentence to be true or otherwise are substitutional quantifiers. I will argue that there is a philosophically rather important class of quantified expressions in English that act quite differently, a class that includes something, nothing, and several things. In addition to expressing quantification, such expressions act like nominalizations, introducing a new domain of objects that would not have been present in the semantic structure of the sentence otherwise. The entities those expressions introduce are of just the same sort as those that certain ordinary nominalizations refer to (such as John's wisdom or John's belief that S), namely they are tropes or entities related to tropes. Analysing certain quantifiers as nominalizing quantifiers will shed a new light on philosophical issues such as the status of properties and the nature of propositional attitudes.     

Norms on the gender perception of role nouns in Czech,English, French,German, Italian,Norwegian, and Slovak

We collected norms on the gender stereotypicality of an extensive list of role nouns in Czech, English, French, German, Italian, Norwegian, and Slovak, to be used as a basis for the selection of stimulus materials in future studies. We present a Web-based tool (available at https://www.unifr.ch/lcg/) that we developed to collect these norms and that we expect to be useful for other researchers, as well. In essence, we provide (a) gender stereotypicality norms across a number of languages and (b) a tool to facilitate cross-language as well as cross-cultural comparisons when researchers are interested in the investigation of the impact of stereotypicality on the processing of role nouns.     

Testing the dimensional comparison theory: When do students prefer dimensional comparisons to social and temporal comparisons?

Students compare their achievement in a subject with their classmates’ achievements (social comparison), their own prior achievements (temporal comparison), and their achievements in other subjects (dimensional comparison), which can each be better (upward comparison), equal (lateral comparison), or worse (downward comparison). Prior research has investigated the impact of different comparison motivations on the prevalence of social and temporal comparisons, but no study has examined the same for dimensional comparisons yet. The present study closes this gap: A total of 605 German high school students were presented with four situations, in which a fictitious student receives the same objective feedback for an exam in a certain subject, but is motivated either to evaluate, to enhance, to improve, or to differentiate himself. For each comparison motivation, the participants judged how likely the fictitious student was to draw dimensional, social, and temporal upward, lateral, and downward comparisons. As a central result, dimensional comparisons in all directions had the highest prevalences under the self-differentiation motivation. In contrast, the prevalences of dimensional comparisons were relatively low under the other three motivations. This finding complements the recently developed dimensional comparison theory. For the first time, we could empirically show that dimensional comparisons primarily serve self-differentiation motivations.     

Incidental learning of S-R contingencies in the masked prime task

Subliminal motor priming effects in the masked prime paradigm can only be obtained when primes are part of the task set. In 2 experiments, the authors investigated whether the relevant task set feature needs to be explicitly instructed or could be extracted automatically in an incidental learning paradigm. Primes and targets were symmetrical arrows, with target color, not shape, the response-relevant feature. Shape and color covaried for targets (e.g., <> always blue, >< always green), whereas primes were always black. Over time, a negative compatibility effect (NCE; response benefits when prime and target had different shapes) developed, indicating that primes affected the motor system. When target shape and color varied independently (control condition), no NCE occurred, in line with the assumption that the NCE reflects task set-dependent motor processes, not perceptual interactions.
