Apperception in primed problem solving

Mental representation is a central theoretical concept in modern cognitive psychology. However, its investigation has been predominantly based on inapt perceptualist concepts, which presume that information contents in them, i.e., mental contents, solely arise from stimulus. This is in spite of the evidence that much in human thought does not have any sensory equivalence. Consequently, we make a difference between perception and apperception, as e.g., Kant and Wundt did, and argue in favor of a detailed analysis of this mental process that is responsible for the construction of representations. We present here five primed problem solving experiments. The basic idea was to demonstrate that depending on priming information people represent perceptually identical stimuli very differently, i.e., they ascribe different uses and meanings to objects and they integrate them differently to compose distinct solutions. In this vein, we demonstrate that people regularly rely on information, which is not or cannot be perceived in principle. On the ground of our empirical findings, we resurrect the issue on why the difference between perception and apperception is theoretically adequate and introduce some central concepts for the theoretical analysis of apperception such as "seeing as" and functional binding.     

Increasing accurate preference assessment implementation through pyramidal training

Preference assessments directly evaluate items that may serve as reinforcers, and their implementation is an important skill for individuals who work with children. This study examined the effectiveness of pyramidal training on teachers' implementation of preference assessments. During Experiment 1, 3 special education teachers taught 6 trainees to conduct paired-choice, multiple-stimulus without replacement, and free-operant preference assessments. All trainees acquired skills necessary to implement preference assessments with 90% or greater accuracy during the training sessions and demonstrated generalization of skills to their classrooms or clinic. During Experiment 2, 5 teachers who served as trainees in Experiment 1 trained 18 preschool teachers. All preschool teachers met the mastery criterion following training. Training teachers to implement preference assessments may increase teachers' acceptance and use of behavior-analytic procedures in school settings.     

Judgments about moral responsibility and determinism in patients with behavioural variant of frontotemporal dementia: still compatibilists

Do laypeople think that moral responsibility is compatible with determinism? Recently, philosophers and psychologists trying to answer this question have found contradictory results: while some experiments reveal people to have compatibilist intuitions, others suggest that people could in fact be incompatibilist. To account for this contradictory answers, Nichols and Knobe (2007) have advanced a ‘performance error model’ according to which people are genuine incompatibilist that are sometimes biased to give compatibilist answers by emotional reactions. To test for this hypothesis, we investigated intuitions about determinism and moral responsibility in patients suffering from behavioural frontotemporal dementia. Patients suffering from bvFTD have impoverished emotional reaction. Thus, the ‘performance error model’ should predict that bvFTD patients will give less compatibilist answers. However, we found that bvFTD patients give answers quite similar to subjects in control group and were mostly compatibilist. Thus, we conclude that the ‘performance error model’ should be abandoned in favour of other available model that best fit our data.     

The Gaussian Graphical Model in Cross-Sectional and Time-Series Data

We discuss the Gaussian graphical model (GGM; an undirected network of partial correlation coefficients) and detail its utility as an exploratory data analysis tool. The GGM shows which variables predict one-another, allows for sparse modeling of covariance structures, and may highlight potential causal relationships between observed variables. We describe the utility in three kinds of psychological data sets: data sets in which consecutive cases are assumed independent (e.g., cross-sectional data), temporally ordered data sets (e.g., n = 1 time series), and a mixture of the 2 (e.g., n > 1 time series). In time-series analysis, the GGM can be used to model the residual structure of a vector-autoregression analysis (VAR), also termed graphical VAR. Two network models can then be obtained: a temporal network and a contemporaneous network. When analyzing data from multiple subjects, a GGM can also be formed on the covariance structure of stationary means—the between-subjects network. We discuss the interpretation of these models and propose estimation methods to obtain these networks, which we implement in the R packages graphicalVAR and mlVAR. The methods are showcased in two empirical examples, and simulation studies on these methods are included in the supplementary materials.     

Emotional expressivity in men and women: Stereotypes and self-perceptions

Three studies were conducted to assess prevalent stereotypes regarding men's and women's emotional expressivity as well as self-perceptions of their emotional behaviour. Emotion profiles were employed to assess both modal emotional reactions and secondary emotional reactions to hypothetical events and personal experiences. In Study 1 we asked how men and women in general would react to a series of hypothetical emotional events. In Study 2 we asked how participants themselves expected to react to these same situations and in Study 3 we asked participants to report a personal emotional event in narrative form. Two gender differences emerged across all three studies. Specifically, women were expected to be more likely to react with sadness to negative emotion-eliciting events in general. They also expected themselves to be more likely to react with sadness as well as to cry and to withdraw more when experiencing negative emotional events. Finally, women report more sadness when describing personal events. In contrast, men were expected to react with more happiness/serenity during negative emotional situations. Also, they expect themselves to react more frequently this way as well as to laugh and smile more and to be more relaxed in negative situations. Finally, men tend to report more happiness when describing negative personal events. In sum, the present study gives a more detailed portrayal of how men and women are expected and expect themselves to react to specific emotional situations and presents some evidence that these expectations may influence the way they reconstruct emotional events from their past.     

Responses to olfactory stimuli in spotted hyenas (Crocuta crocuta): II. Discrimination of conspecific scent

Scent marking in spotted hyenas (Crocuta crocuta) includes the deposition of anal sac secretions, or "paste," and presumably advertises territorial ownership. To test whether captive hyenas classify and discriminate individuals using odor cues in paste, the authors conducted behavioral discrimination bioassays and recorded hyena investigation of paste extracted from various conspecific donors. In Experiment 1, subjects directed most investigative behavior toward scents from unfamiliar hyenas and members of the opposite sex. In Experiment 2, male hyenas discriminated between concurrent presentations of paste from various unfamiliar females in similar reproductive states. Thus, pasted scent marks convey information about the sex, familiarity, and even identity of conspecifics. Aside from territory maintenance, scent marking may also communicate information about individual sexual status.     

Assessing the efficacy of pictorial preference assessments for children with developmental disabilities

Past research has demonstrated that pictorial preference assessments can predict subsequent reinforcement effects for individuals with developmental disabilities only when access to the selected stimulus is provided contingent on a pictorial selection. The purpose of the present investigation was to assess more comprehensively the feasibility of the pictorial format with children with developmental disabilities. In Experiment 1, prerequisite skill assessments were conducted, and the role of a contingent reinforcer was assessed by comparing the results from the pictorial assessment without contingent access to a reinforcer assessment. If contingent access was found to be necessary, the effects of schedule thinning were evaluated to determine whether a pictorial format could be made more practical in Experiment 2. The pictorial format without contingent access was successful with only some participants. However, schedule thinning was found to be an effective method to establish conditioned reinforcement properties for pictorial stimuli to create a more practical assessment for a subset of participants.     

Genetic and environmental influences on the association between performance‐based self‐esteem and exhaustion: A study of the self‐worth notion of burnout

In the self‐worth model, burnout is considered to be a syndrome of performance‐based self‐esteem (PBSE) and experiences of exhaustion. Studies have shown that PBSE and burnout indices such as Pines’ Burnout Measure (BM) are associated. Whether these variables have overlapping etiologies has however not been studied before. Genetic and environmental components of covariation between PBSE and exhaustion measured with Pines’ BM were examined in a bivariate Cholesky model using data from 14,875 monozygotic and dizygotic Swedish twins. Fifty‐two per cent of the phenotypic correlation (r = 0.41) between PBSE and Pines’ BM was explained by genetics and 48% by environmental factors. The findings of the present study strengthen the assumption that PBSE should be considered in the burnout process as proposed by the self‐worth conception of burnout. The present results extend our understanding of the link between this contingent self‐esteem construct and exhaustion and provide additional information about the underlying mechanisms in terms of genetics and environment. This finding corroborates the assumed syndrome view on burnout, while it also suggests an altered view of how the syndrome emerges and how it can be alleviated.
