Transparency and the KK Principle

An important question in epistemology is whether the KK principle is true, i.e., whether an agent who knows that p is also thereby in a position to know that she knows that p. We explain how a “transparency” account of self‐knowledge, which maintains that we learn about our attitudes towards a proposition by reflecting not on ourselves but rather on that very proposition, supports an affirmative answer. In particular, we show that such an account allows us to reconcile a version of the KK principle with an “externalist” or “reliabilist” conception of knowledge commonly thought to make that principle particularly problematic.     

The semantics of syntactic structures

Over the past 15 years, both linguists and psycholinguists have shown a growing interest in the idea that syntactic structures can carry meanings that are independent of the meanings of specific words. This article considers how this idea relates to traditional notions of compositionality in generative grammar, and examines two modern theories that, although based on different starting assumptions, both readily allow syntactic structures to bear independent meaning. We review work from psycholinguistics suggesting that observation alone is often insufficient to support the efficient learning of word meanings, and that some of the 'slack' left by observation can be picked up by the semantics of the syntactic structures in which words appear. We argue that this convergence between linguistic theory and psycholinguistic experimentation should be no surprise, because language must be learnable.     

Against all odds – is a more differentiated view of personality development in emerging adulthood needed? The case of young apprentices

Personality development in emerging adults who do not attend college after high school has been largely overlooked so far. In this study, we investigated personality development in emerging German adults (N_T1 = 1,886, M_ageT1 = 18.01 years, 29% female) undergoing vocational education and training (VET). The trainees were assessed at the start of VET, 1.5 years later, and another 1.5 years after that, just before graduation. Longitudinal latent change score analyses were applied. Bivariate analyses investigated life satisfaction and job strain as social and work‐related aspects that are potentially reciprocally related to personality development. Mean‐level personality changes included increases in neuroticism and decreases in agreeableness and conscientiousness in the first interval. In the second interval, neuroticism decreased and conscientiousness increased. Simultaneously, trainees reported a gradual decrease in extraversion and openness across the 3‐year time span. Personality, especially agreeableness and conscientiousness, emerged as a stronger predictor of changes in job strain and life satisfaction than vice versa. For example, more agreeable and more conscientious trainees subsequently showed increases in life satisfaction. Trainees reporting higher job strain subsequently showed decreases in agreeableness. Trajectories of personality development partly support the maturity principle that has been established in many college student samples.     

Using Dynamic Panel Models to Study Age‐related Differences and Time‐related Changes in Personality

Along with an increasing interest in the plasticity and role of personality across the adult lifespan comes the need for a diverse set of innovative statistical approaches to study it. With this paper, we set out to illustrate some of the possibilities and challenges in modelling age‐related differences and time‐related changes in personality psychology by means of dynamic panel models. To this end, we first distinguish between the study of age‐related differences and time‐related changes and demonstrate how the treatment of age and time as either discrete or continuous variables implies important modelling choices. Second, we present a selection of four example cases that address the topic of age moderation in diverse matters and with different objectives. Based on our cross‐tabulation of age and time as discrete and continuous variables, the first two example cases represent fairly well‐established models (cases A and B), whereas the remaining cases are used to illustrate current developments in the field (cases C and D). We close the paper with some final remarks on current limitation and future research directions. © 2019 European Association of Personality Psychology     

The link between social interactions and trust recovery in customer–business relationships

Trust plays a crucial role in interpersonal relationships, including customer–company relationships, where the customer expects that a company will behave predictably in any particular situation. Companies do not always fulfill customers' expectations and thereby breach the trust relationship. To avoid negative consequences of this trust violation, companies may issue a formal apology as one possible path to regaining customer trust. In the same way, a previous social interaction, which can increase the customer's levels of oxytocin, can help to recover trust after service failures. In this study, three experiments were conducted as follows: the first manipulating a simulated social interaction with images; the second manipulating a physical social interaction, (i.e., a hug); and the third with exogenous oxytocin administration. The results showed that both physical interaction, (i.e., a hug) and simulated social interaction, (i.e., images of people interacting with each other) had a positive effect on customer trust recovery and provided support for oxytocin release as the underlying mechanism in this process. This research contributes to understanding of the link between social interactions and trust by elucidating the effects of both simulated and physical interactions on trust recovery.     

Gender-stereotyped preferences in childhood and early adolescence: A comparison of cross-sectional and longitudinal data

Children are exposed to a gender-specific environment on an everyday basis through media, books, school supplies and especially toys. Children’s movies and television programs were found to portray protagonists’ occupational and private roles in a very traditional, gender-stereotypical way. The present two studies aimed to investigate gender-specific preferences in childhood and early adolescence. Cross-sectional data (study 1) were compared to longitudinal one (study 2) as we specifically aimed to investigate changes in gender preferences over time. A person-oriented approach, namely Configural Frequency Analysis was applied, to categorically analyze the relationship and development of gender-stereotyped preferences throughout childhood and early adolescence. Consistent with former studies, study 1 showed that gender-stereotypical preferences increased by age, for boys to a higher extent than for girls. By the age of twelve, these preferences had decreased supporting the theory of Kohlberg that children’s gender-stereotypic preferences continuously grow until around six years of age to finally lower thereafter. Gender-specific preferences generally became much more flexible over time.     

Lag-1 sparing in the attentional blink: Benefits and costs of integrating two events into a single episode

When people monitor a visual stream of rapidly presented stimuli for two targets (T1 and T2), they often miss T2 if it falls into a time window of about half a second after T1 onset—the attentional blink. However, if T2 immediately follows T1, performance is often reported being as good as that at long lags—the so-called Lag-1 sparing effect. Two experiments investigated the mechanisms underlying this effect. Experiment 1 showed that, at Lag 1, requiring subjects to correctly report both identity and temporal order of targets produces relatively good performance on T2 but relatively bad performance on T1. Experiment 2 confirmed that subjects often confuse target order at short lags, especially if the two targets are equally easy to discriminate. Results suggest that, if two targets appear in close succession, they compete for attentional resources. If the two competitors are of unequal strength the stronger one is more likely to win and be reported at the expense of the other. If the two are equally strong, however, they will often be integrated into the same attentional episode and thus get both access to attentional resources. But this comes with a cost, as it eliminates information about the targets' temporal order.     

Retrieval during learning facilitates subsequent memory encoding

In multiple-list learning, retrieval during learning has been suggested to improve recall of the single lists by enhancing list discrimination and, at test, reducing interference. Using electrophysiological, oscillatory measures of brain activity, we examined to what extent retrieval during learning facilitates list encoding. Subjects studied 5 lists of items in anticipation of a final cumulative recall test and did either a retrieval or a no-retrieval task between study of the lists. Retrieval was from episodic memory (recall of the previous list), semantic memory (generation of exemplars from an unrelated category), or short-term memory (2-back task). Behaviorally, all 3 forms of retrieval enhanced recall of both previously and subsequently studied lists. Physiologically, the results showed an increase of alpha power (8-14 Hz) from List 1 to List 5 encoding when no retrieval activities were interpolated but no such increase when any of the 3 retrieval activities occurred. Brain-behavior correlations showed that alpha-power dynamics from List 1 to List 5 encoding predicted subsequent recall performance. The results suggest that, without intermittent retrieval, encoding becomes ineffective across lists. In contrast, with intermittent retrieval, there is a reset of the encoding process for each single list that makes encoding of later lists as effective as encoding of early lists.     

Der Gruppenfragebogen (GQ-D)

An investigation of the psychometric properties of the German version of the Group Questionnaire (GQ; Krogel 2009) is described. The GQ is a self-report instrument economically enabling the assessment of helpful aspects of relationships within small groups. Due to the limited length of the questionnaire it provides a tool of monitoring bonding to the group, the quality of the working relationship as well as negative aspects during group treatment. One advantage of the GQ is that it measures relationships on three different relational levels (group members, group leader and the group as a whole). Following a test of the multidimensional structure of the GQ-D using data from a multisite study (N=438) with structural equation models, the GQ-D was validated using other process measures. The GQ-D proved to be an objective, valid and reliable measure to assess relevant therapeutic relationships within groups.
