Ageing-related stereotypes in memory: When the beliefs come true

Age-related stereotype concerns culturally shared beliefs about the inevitable decline of memory with age. In this study, stereotype priming and stereotype threat manipulations were used to explore the impact of age-related stereotype on metamemory beliefs and episodic memory performance. Ninety-two older participants who reported the same perceived memory functioning were divided into two groups: a threatened group and a non-threatened group (control). First, the threatened group was primed with an ageing stereotype questionnaire. Then, both groups were administered memory complaints and memory self-efficacy questionnaires to measure metamemory beliefs. Finally, both groups were administered the Logical Memory task to measure episodic memory, for the threatened group the instructions were manipulated to enhance the stereotype threat. Results indicated that the threatened individuals reported more memory complaints and less memory efficacy, and had lower scores than the control group on the logical memory task. A multiple mediation analysis revealed that the stereotype threat effect on the episodic memory performance was mediated by both memory complaints and memory self-efficacy. This study revealed that stereotype threat impacts belief in one's own memory functioning, which in turn impairs episodic memory performance.     

Is retrieval the key? Metamemory judgment and testing as learning strategies

Re-reading is the most common learning strategy, albeit not a very efficient one. Testing is highly efficient, but not perceived by students as a learning strategy. Prospective judgment-of-learning (JOL) reflect the learner's impression of subsequently being able to retrieve the ongoing learning in a cued-recall task. Estimating JOL involves attempting to retrieve the information, as in testing. The few studies that have explored the potential mnemonic benefit of JOL have yielded contradictory results. Our aim was to compare JOL and testing with re-study and to examine the impact of these strategies according to the relative difficulty of the material (cue-target association strength) in two experiments. After a first encoding phase, participants re-studied, provided JOL, or took a test. Forty-eight hours later, they participated in a final cued-recall test, during which their confidence level judgments were collected. The main result was that delayed JOL behaved in the same way as testing, and both yielded better performances than re-study when material was of moderate difficulty. The easy or very difficult material revealed no differences between these strategies. JOL is proposed as an alternative to testing when faced with difficult material.     

Moral Beliefs for the Error Theorist?

The moral error theory holds that moral claims and beliefs, because they commit us to the existence of illusory entities, are systematically false or untrue. It is an open question what we should do with moral thought and discourse once we have become convinced by this view. Until recently, this question had received two main answers. The abolitionist proposed that we should get rid of moral thought altogether. The fictionalist, though he agreed we should eliminate moral beliefs, enjoined us to replace them with attitudes that resemble to some extent the attitudes we have towards pieces of fiction. But there is now a third theory on the market: conservationism, the view that we should keep holding moral beliefs, even though we know them to be false. (According to a fourth theory, ‘substitutionism’, we should modify the content of our moral claims in such a way that they become true.) Putting abolitionism (and substitutionism) aside, our aim is to assess the plausibility of conservationism as an alternative to the – relatively dominant – fictionalism that we find in the literature. Given the difficulty of finding a conservationist view that is both (i) plausible and (ii) not merely a terminological variant of fictionalism, we will argue that conservationism fails to constitute a plausible alternative to fictionalism, at least insofar as it purports to be an alternative view as to what we should do with our moral thoughts.     

Age-based discrimination of rival males in western bluebirds

Adaptive social behavior frequently involves discriminating between classes of individuals such as relatives versus non-relatives, older versus younger individuals, or individuals of different status. In the absence of spatial cues, this discrimination may be based on signals that correlate with fitness-related traits (e.g., older or high-status males may sing higher performance songs) or with identity, for example, when receivers distinguish and classify signalers based on their unique signal structure. Here, we examine vocal age-based discrimination in western bluebirds (Sialia mexicana), a North American songbird in which older males have a significant advantage in obtaining extra-pair fertilizations, and therefore pose a significantly higher threat to paternity than younger males. We asked whether western bluebird males showed a higher response to playback of songs of older males compared to younger males relative to their own age. We prepared song stimuli by removing three potential signals of age that have been identified as important in other species: (1) note consistency (which was achieved by playing a single instance of each note repeatedly), (2) note repertoire size, and (3) singing rate (the latter two were equalized across conditions). Even in the absence of these potential signals of age, young males responded more strongly to playback of older males’ songs than to young males’ songs, suggesting that they are able to discriminate between age classes relative to the threat they pose. Further research is required to determine whether this discrimination is based on individual recognition or signal features that are correlated with age.     

Anomalous experiences and schizotypy: which comes first? The Hermit Crab syndrome hypothesis

This study confirms findings of previous research as they state that some triggering events or anomalous experiences can give rise to a disruption of cognitive processes and emotional changes in a predisposed person. Furthermore, our research states that the cognitive process and change of world view (paradigm shift (PS)) accompanying some paranormal experiences (PEs) could facilitate the development of a schizotypal personality structure. For the purposes of this study, 675 young people aged between 13 and 25 years old (M?=?16.8, SD?=?1.9) completed the Schizotypal Personality Questionnaire, the Revised and Modified Paranormal Belief Scales, the measurement of eight kinds of PE and a self-reported measurement of change of world view. The results confirm the mediating role of PS between paranormal practices and schizotypy as the cognitive process contributing to symptom formation as well as to symptom maintenance. The said results also confirm the existence of cognitive–emotional stages, also called Hermit Crab syndrome, in the process of the “paranormalisation” of reality.     

Jazz Redux: a reply to Möller

This paper is a response to Niklas Möller’s (Philosophical Studies, 2013) recent criticism of our relational (Jazz) model of meaning of thin evaluative terms. Möller’s criticism rests on a confusion about the role of coordinating intentions in Jazz. This paper clarifies what’s distinctive and controversial about the Jazz proposal and explains why Jazz, unlike traditional accounts of meaning, is not committed to analycities.
