The tip-of-the-tongue phenomenon: Blocking or partial activation?

Tip-of-the-tongue states may represent the momentary unavailability of an otherwise accessible word or the weak activation of an otherwise inaccessible word. In three experiments designed to address these alternative views, subjects attempted to retrieve rare target words from their definitions. The definitions were followed by cues that were related to the targets in sound, by cues that were related in meaning, and by cues that were not related to the targets. Experiment 1 found that compared with unrelated cues, related cue words that were presented immediately after target definitions helped rather than hindered lexical retrieval, and that sound cues were more effective retrieval aids than meaning cues. Experiment 2 replicated these results when cues were presented after an initial target-retrieval attempt. These findings reverse a previous one (Jones, 1989) that was reproduced in Experiment 3 and shown to stem from a small group of unusually difficult target definitions.     

Versuche zur multidimensionalen Skalierung von subjektiven Reizähnlichkeiten auf Grund von Schätzurteilen,Entscheidungszeiten und Verwechslungshäufigkeiten beim Wiedererkennen

Zusammenfassung Es wird über drei Experimente berichtet, in denen auf verschiedene Art und Weise subjektive Ähnlichkeitsbeziehungen zwischen Reizen ermittelt worden sind. Während im Versuch I Distanzen zwischen den Objekten auf Grund direkter Ähnlichkeitsschätzungen gewonnen wurden, sind im Experiment II die Ähnlichkeitsbeziehungen aus Entscheidungszeiten definiert worden, die von der Darbietung der Reizpaare bis zur Urteilsabgabe benötigt worden sind. Im Versuch III ist schließlich die Anzahl der Verwechslungen beim Wiedererkennen als quantitativer Ausdruck für die Ähnlichkeit verwandt worden.Mit Methoden der multidimensionalen Skalierung sind die aus den Ähnlichkeitsmatrizen analysierbaren Ordnungsgesichtspunkte ermittelt worden. Ihre psychologische Deutung ist durch Benennung der Skalen und durch Versuche zur Rekonstruktion der Urteils- bzw. Wiedererkennungsprozesse versucht worden. In den ersten beiden Versuchen konnten je drei interpretierbare Dimensionen ermittelt werden. Experiment III erbrachte einen weiteren vierten Faktor. Beim Vergleich der drei Ähnlichkeitsstrukturen konnten für jeweils zwei Skalen inhaltliche Übereinstimmungen erkannt werden. Dabei zeigten die auf Entscheidungszeiten zurückgehenden Dimensionen den jeweils geringsten Differenzierungsgrad mit nur wenigen Unterscheidungsklassen. Die verbleibenden Faktoren konnten weitgehend auf spezielle Bedingungen des jeweiligen Versuches zurückgeführt werden.

Experiments in multidimensional scaling of subjective stimulus similarities based on ratings, descion times, and confusions in recognition

Summary This is a paper showing in different ways subjective relations of similarity between stimuli. While in experiment No. I distances between objects have been won due to direct ratings of similarity, the relations of similarity in experiment No. II have been defined from the time of presentation of the pairs of stimuli until the stating of judgement. In experiment No. III, finally, the number of mistakes in recognition were used as a quantitative expression of similarity.The analyzable aspects of classification, which were used by the Ss, have been won by means of procedures of multidimensional scaling. A psychological interpretation has been tried by denominating the scales and by tyring to reconstruct the processes of judgement respectively recognition. In each of the first two experiments three interpretable dimensions were found. Experiment No.III showed a further fourth factor. When comparing the three structures of similarity, agreement in content could be found out for the first two scales as well as for the second ones. The dimensions going back to the decision times showed the least rate of differentiation with only few classes of discrimination. The remaining factors could be attributed mostly to the special conditions of each of the experiments.

     

TECHNOLOGY,THEOLOGY, AND SPIRITUALITY IN THE DIGITAL AGE

Digitalization and the development of Artificial Intelligence (AI) will bring about substantial changes in all aspects of life. This happens in a world marked by the poisonous synergy of five Ps, polarization, populism, protectionism, post‐truth, patriarchy, as well as an ambiguous interplay of secularization and new visibility of religion. If development of AI is to be beneficial for people and planet a number of challenges must be met. In this regard, religion‐and‐science dialogue needs improvement in making things not only intellectually but also spiritually fit. Ethics should be involved from the beginning rather than being called upon first when problems arise. Faith communities have a prophetical, diaconal, ethical, and theological role. Based on the characterization of life as a fourfold web of relationality, personal, social, political, as well as global issues are identified and discussed. These include mental health disorders, addiction, manipulation, and self‐exploitation. Reflections on leadership suggest resilience, coexistence, and hope as theological key components for navigating the uncharted realms of the digital age.     

Exploring Diurnal Cortisol Rhythms of Kindergarten Teachers in Kosovo and Ukraine

Teachers’ stress is a dynamic combination of the individual teacher's characteristics and characteristics of the classroom and school environment. To date, there are limited studies on teachers’ stress in the context of lower‐middle‐income countries (LMICs), where working conditions as well as general political and economic circumstances might pose a considerable threat for teachers’ well‐being. This study explores whether certain combinations of individual and environmental experiences of teachers in LMICs may result in stress, assessed as patterns of diurnal cortisol rhythm. Participants were kindergarten teachers in Kosovo and Ukraine, two LMICs in Europe. Latent Profile Analysis identified three subgroups of teachers that significantly differed on teachers’ education and experience. Preliminary results of Latent Growth Modeling suggested differences between profiles in baseline waking cortisol and patterns of diurnal decline. Teachers in the profile that was characterized by the longest experience working in the field but the lowest level of education showed blunted cortisol in the morning and a flatter slope; a pattern that could indicate a maladaptive cortisol response. Future directions for studying stress processes among teachers in LMICs and implications for policy and practice on how to support teacher well‐being in low‐resource contexts are discussed.     

Unambiguous generalization effects after treatment of non-canonical sentence production in German agrammatism

Agrammatism is-among others, characterized by a deficit in producing grammatical structures. Of specific difficulty is the utilization of complex, non-canonical sentence structures (e.g. object-questions, passives, object-clefts). Several studies have documented positive effects when applying a specific treatment protocol in terms of increasingly correct production of target complex sentence structures with some variance in generalization patterns noted across individuals. The objective of this intervention study was to evaluate an intervention program focussing on the production of non-canonical sentences. Hypotheses about the occurrence of treatment effects were formulated on the basis of syntactic complexity, referring to the amount of syntactic phrase structures necessary to generate specific German sentence structures. A multiple single case study with seven agrammatic participants was applied, each participant receiving training in the production of object-relative-clauses and who-questions. The investigation was designed to unambiguously evaluate for each individual, structure specific and generalized learning effects with respect to the production of object-relative-clauses, who-questions and passive sentences. Results showed significant improvements for all sentences types. This outcome is considered within methodological issues of treatment studies. Theoretical and clinical implications are discussed.     

Top-down effects of semantic knowledge in visual search are modulated by cognitive but not perceptual load

Moores, Laiti, and Chelazzi (2003) found semantic interference from associate competitors during visual object search, demonstrating the existence of top-down semantic influences on the deployment of attention to objects. We examined whether effects of semantically related competitors (same-category members or associates) interacted with the effects of perceptual or cognitive load. We failed to find any interaction between competitor effects and perceptual load. However, the competitor effects increased significantly when participants were asked to retain one or five digits in memory throughout the search task. Analyses of eye movements and viewing times showed that a cognitive load did not affect the initial allocation of attention but rather the time it took participants to accept or reject an object as the target. We discuss the implications of our findings for theories of conceptual short-term memory and visual attention.     

Can Virtual Reality Increase the Realism of Role Plays Used to Teach College Women Sexual Coercion and Rape-Resistance Skills?

The present study evaluated whether virtual reality (VR) can enhance the realism of role plays designed to help college women resist sexual attacks. Sixty-two female undergraduate students were randomly assigned to either the Role Play (RP) or Virtual Role Play (VRP) conditions, which were differentiated only by the use of VR technology in the VRP condition. A multimethod assessment strategy was used to evaluate the effects of VR on the experienced realism of sexually threatening role plays. Realism was assessed by participant self-reports of negative affect and perceptions of realism, direct observation of participants' verbal displays of negative affect during the role plays, and measurements of participant heart rate during the role plays. Results indicated that VR can indeed heighten the realism of sexually threatening role plays. Discussion focuses on issues regarding the use of VR-enhanced role plays for helping college women resist sexual attacks.     

The Role of Social Network Structure in the Emergence of Linguistic Structure

Social network structure has been argued to shape the structure of languages, as well as affect the spread of innovations and the formation of conventions in the community. Specifically, theoretical and computational models of language change predict that sparsely connected communities develop more systematic languages, while tightly knit communities can maintain high levels of linguistic complexity and variability. However, the role of social network structure in the cultural evolution of languages has never been tested experimentally. Here, we present results from a behavioral group communication study, in which we examined the formation of new languages created in the lab by micro-societies that varied in their network structure. We contrasted three types of social networks: fully connected, small-world, and scale-free. We examined the artificial languages created by these different networks with respect to their linguistic structure, communicative success, stability, and convergence. Results did not reveal any effect of network structure for any measure, with all languages becoming similarly more systematic, more accurate, more stable, and more shared over time. At the same time, small-world networks showed the greatest variation in their convergence, stabilization, and emerging structure patterns, indicating that network structure can influence the community's susceptibility to random linguistic changes (i.e., drift).     

Early activation of object names in visual search

In a visual search experiment, participants had to decide whether or not a target object was present in a fourobject search array. One of these objects could be a semantically related competitor (e.g.,shirt for the targettrousers) or a conceptually unrelated object with the same name as the target—for example,bat (baseball) for the targetbat (animal). In the control condition, the related competitor was replaced by an unrelated object. The participants’ response latencies and eye movements demonstrated that the two types of related competitors had similar effects: Competitors attracted the participants’ visual attention and thereby delayed positive and negative decisions. The results imply that semantic and name information associated with the objects becomes rapidly available and affects the allocation of visual attention.
