Two Types of Competitiveness: Their Impact on the Perceived Interpersonal Attractiveness of Women and Men1

Previous research by Riskind and Wilson (1982) found that competitiveness in men was associated with perceptions of enhanced interpersonal attractiveness. This research used a single, global definition of competitiveness. The present study extended this earlier research by using two types of competitiveness, goal and interpersonal competitiveness, and by examining the perceived interpersonal attractiveness of competitive women as well as men. It was found that these two types of competitiveness generally have opposite effects. Goal competitiveness, in which one desires to attain a goal and to do one's best, was primarily perceived as enhancing interpersonal attractiveness. By contrast, interpersonal competitiveness, in which one desires to do better than others and to win over other people, showed fewer effects, but was primarily perceived as detracting from interpersonal attractiveness.     

Dynamics of metacognitive judgments: pre- and postretrieval mechanisms

Two experiments examined the temporal course of pre- and postretrieval mechanisms using a new kind of dynamic metacognitive judgment. Experiment 1 presented participants with primed and unprimed triples of remote associates to a target word and required them to provide repeated metacognitive judgments, 4 times during a 12-s interval, about the likelihood that they would later recognize the target. Both familiarity with the words and the processing time were associated with changes in metacognitive evaluations. Experiment 2 placed pre- and postretrieval mechanisms in opposition by transforming an element of a previously primed question. For transformed questions this led to high initial ratings, which decreased over time, while for novel questions the ratings were initially lower and increased with time. The results are discussed in terms of pre- and postretrieval mechanisms interacting over time.     

Olfactory learning in individually assayed Drosophila larvae

Insect and mammalian olfactory systems are strikingly similar. Therefore, Drosophila can be used as a simple model for olfaction and olfactory learning. The brain of adult Drosophila, however, is still complex. We therefore chose to work on the larva with its yet simpler but adult-like olfactory system and provide evidence for olfactory learning in individually assayed Drosophila larvae. We developed a differential conditioning paradigm in which odorants are paired with positive (“+” fructose) or negative (“-” quinine or sodium chloride) gustatory reinforcers. Test performance of individuals from two treatment conditions is compared—one received odorant A with the positive reinforcer and odorant B with a negative reinforcer (A+/B-); animals from the other treatment condition were trained reciprocally (A-/B+). During test, differences in choice between A and B of individuals having undergone either A+/B- or A-/B+ training therefore indicate associative learning. We provide such evidence for both combinations of reinforcers; this was replicable across repetitions, laboratories, and experimenters. We further show that breaks improve performance, in accord with basic principles of associative learning. The present individual assay will facilitate electrophysiological studies, which necessarily use individuals. As such approaches are established for the larval neuromuscular synapse, but not in adults, an individual larval learning paradigm will serve to link behavioral levels of analysis to synaptic physiology.     

On the Relation Between Religiosity and the Endorsement of Conspiracy Theories: The Role of Political Orientation

Religious and conspiracy beliefs share the feature of assuming powerful forces that determine the fate of the world. Correspondingly, they have been theorized to address similar psychological needs and to be based on similar cognitions, but there exist little authoritative answers about their relationship. We delineate two theory-driven possibilities. If conspiracy theories and religions serve as surrogates for each other by fulfilling similar needs, the two beliefs should be negatively correlated. If conspiracy and religious beliefs stem from the same values and cognitions, this would speak for a positive correlation that might be diminished—for example—by controlling for shared political ideologies. We approached the question with a meta-analysis (N = 10,242), partial correlations from large Christian-dominated datasets from Germany, Poland, and the United States (N = 12,612), and a preregistered U.S. study (N = 500). The results indicate that the correlations between religiosity and conspiracy theory endorsement were positive, and political orientation shared large parts of this covariance. Correlations of religiosity with the more need-related conspiracy mentality differed between countries. We conclude that similarities in the explanatory style and ideologies seem to be central for the relation between intrinsic religiosity and endorsing conspiracy theories, but psychological needs only play a minor role.     

Determinants of the purchase intention of non-fungible token collectibles

Disrupting the concept of ownership in the digital space, non-fungible tokens (NFTs) have created unprecedented market opportunities and captivated millions of investors. Characterized by artificial scarcity and ensured authenticity, the technical implementation establishes novel parameters for digital ownership and collecting, underscoring a research gap where the determinants of consumer behavior are yet to be studied. This paper presents a research model based on the Stimulus-Organism-Response (SOR) model to investigate consumers' purchase intention of NFT-based collectibles (NFTC) for the first time. To develop our model, we identified distinctive NFTC features (functionality, scarcity, aesthetics, and price value) and blockchain characteristics (security and privacy) affecting the utilitarian and hedonic attitude towards NFTC and finally shape NFTC purchase intention. For empirical validation, we conducted an online survey among an NFT-interested target group (N = 356) and analyzed the results by structural equation modeling with SPSS Amos. Findings indicate that the utilitarian attitude toward NFTC is affected by perceived functionality and price value from the product side, and perceived blockchain security and privacy from the technology side. The hedonistic attitude toward NFTC is shaped by perceived functionality, scarcity, and aesthetics. Both attitudes, utilitarian and hedonistic, demonstrate a significant impact on purchase intention. A subsequent mediation analysis confirms that NFTC and blockchain characteristics have an indirect effect on purchase intention. In the under-investigated interface of blockchain technology, digital ownership, and consumer behavior, this work enriches the digital ownership discourse by demonstrating how NFTC create consumer value through product and technology features.     

Finding focus in a difficult landscape: Therapists’ experiences with challenging video guidance processes for parent–infant dyads

Marte Meo video guidance uses filmed interaction of the actual parent–infant dyad in the guidance of caregivers. Exploring the challenges that therapists meet in the guidance of parent–infant dyads may illuminate important aspects of the method itself as well as the therapists’ role and requirements. This could lead to method development and improved practice, but is hitherto little addressed. In this paper, we explore how skilled therapists experience and handle challenging or failing guidance processes with parent–infant dyads. We analyzed interviews with 13 Marte Meo therapists/supervisors using team-based reflexive thematic analysis. Four main themes were identified: promoting relational growth in a coercive context, building an alliance that feels safe for the parents, looking at positive moments in difficult lives, and handling intense feelings as a therapist. Our findings show that therapists experience specific therapeutic and ethical challenges with a vulnerable subgroup of parent–infant dyads where child protective issues arise, where caregivers’ insecurities impede the therapeutic relationship, and where caregivers have unsolved relational or mental health problems. The therapists’ role becomes pivotal and demanding with regard to the therapeutic alliance, the therapeutic interventions in the guidance process, and their own need for regulation, supervision, and structure. Identification of these vulnerable dyads early in the process could facilitate a better adaptation and practice of video guidance. Our findings suggest a need for supporting structures, clinical supervision, and training that address these challenges.     

Hick's Law in a Stochastic Race Model with Speed-Accuracy Tradeoff

We present an analytic solution for a race model of n stochastic accumulators for multiple choice reaction time. We show that to maintain a constant level of accuracy, the response criterion needs to be increased approximately logarithmically with n, to compensate for the increase with n in the likelihood that an incorrect alternative will be most active after any fixed amount of time accumulating information. Assuming that participants monitor and maintain a constant level of performance can then explain the logarithmic dependency of the response latency on n as specified by Hick's law. Moreover, we show that for short time intervals, the Shannon information that observers extract from a stimulus, is predicted to increase linearly with processing time.     

Where Has Our Theory Gone? Learning Theory and Intentional Intervention

Reflecting on the principle that every effective counseling intervention works to the extent that it incorporates sound learning principles, this article emphasizes intentional selection of intervention strategies with reference to 4 learning models: association, reinforcement, cognition‐perceptual, and cognition‐rational/linguistic. Three contexts—developmental, social, and spiritual—are described that require modification of intervention strategy, and a case example is given.
