A Short Measure of the Revised Reinforcement Sensitivity Theory – RSQ17

The need for a research and practical tool, such as a short, reliable, and valid personality assessment test, suggests researchers to create shortened versions of original instruments. Reinforcement sensitivity questionnaire (RSQ) was created in line with some basic premises of revised Reinforcement sensitivity theory, which proposes three motivational and emotional systems: Behavioral inhibition system (BIS), responsible for scanning environment for potential threats, Behavioral activation system (BAS), responsible for aproaching behavior, and the Fight/Flight/Freeze system (FFFS), responsible for behavior in the present threat. RSQ comprises five scales: BIS, BAS, Fight, Flight, and Freeze. The aim of this study was to develop a short version of RSQ, which would be beneficial to both research and practical purposes. Item response theory analyses were used for item selection. The study comprised two samples of participants, whereby Sample 1 (N = 837, 34.6% male, aged 18 – 82, M = 31.63, SD = 13.54) served as the derivation sample, while Sample 2 (818 participants, 43.6% male, 18?75 years, M = 29.65, SD = 12.52) served as validation sample. Factorial validity of the short RSQ was examined on both Sample 1 and Sample 2. Convergent and divergent validity of the short RSQ was examined using RST-PQ, Jackson-5, BIS/BAS scales, and Big Five Inventory. The results point to satisfactory internal consistency, factorial validity, and construct validity of the short RSQ, suggesting that it is an adequate measure for research settings or other contexts which require the use of short personality questionnaires.     

Ältere Menschen als Zeugen vor Gericht

This article provides an overview of the current empirical literature concerning older adults as eyewitnesses. Aging affects perception, memory and eyewitness testimony in many older adults (aged 65 years and above). As a group, they provide shorter accounts in free call, fewer correct and more incorrect details. Often they have to be asked more questions than young witnesses in order to obtain the same amount of information. Age differences have also been demonstrated for answers to questions. There are some promising attempts to improve older witnesses’ testimony, such as the Cognitive Interview. However, replication studies are still needed here. It remains unclear if older witnesses are generally more vulnerable to suggestions than young witnesses. There is some evidence that at least in some situations this seems to be the case. In photographic line-ups young and older adults show similar positive identification rates, but older adults have higher false alarm rates. When viewing mug books, older adults are more likely to make a choice than young adults, which can lead to higher rates of possibly false identification in a subsequent line-up. With increasing age age differences between young and old witnesses also increase. However there is considerable interindividual variation in witness performance: some witnesses are impacted by age early-on, while others remain highly functioning until very old age.     

Unconscious modulation of the conscious experience of voluntary control

How does the brain generate our experience of being in control over our actions and their effects? Here, we argue that the perception of events as self-caused emerges from a comparison between anticipated and actual action-effects: if the representation of an event that follows an action is activated before the action, the event is experienced as caused by one's own action, whereas in the case of a mismatch it will be attributed to an external cause rather than to the self. In a subliminal priming paradigm we show that participants overestimated how much control they had over objectively uncontrollable stimuli, which appeared after free- or forced-choice actions, when a masked prime activated a representation of the stimuli immediately before each action. This prime-induced control-illusion was independent from whether primes were consciously perceived. Results indicate that the conscious experience of control is modulated by unconscious anticipations of action-effects.

Implicit Theories of Creativity of Secondary School Students from Estonia and Russia: Effects of Collectivism,Individualism, and A Bilingual Educational Environment

Implicit theories of creativity provide an understanding of attitude towards among different populations, including students. Insights on how students see and define creativity might help to adjust educational settings and thus make it possible to provide students with better conditions to support their creativity. Although many studies have been conducted on creativity in different cultural settings, little is known on individualism or collectivism is connected to implicit theories of creativity. This study was carried out among secondary school students in Estonia and Russia to identify possible differences in how students from different cultural backgrounds (and varying in individualism and collectivism) define creativity. The results indicated that there were differences in how students from Estonia and Russia defined creativity: Although students from Russia tend to identify creativity more with novel ideas, students from Estonia defined creativity more in terms of self-expression (students from schools with Estonian as the language of instruction) and uniqueness (students from schools with Russian as the language of instruction). Implications and further research suggestions are discussed.     

“Cuts in Action”: A High‐Density EEG Study Investigating the Neural Correlates of Different Editing Techniques in Film

In spite of their striking differences with real‐life perception, films are perceived and understood without effort. Cognitive film theory attributes this to the system of continuity editing, a system of editing guidelines outlining the effect of different cuts and edits on spectators. A major principle in this framework is the 180° rule, a rule recommendation that, to avoid spectators’ attention to the editing, two edited shots of the same event or action should not be filmed from angles differing in a way that expectations of spatial continuity are strongly violated. In the present study, we used high‐density EEG to explore the neural underpinnings of this rule. In particular, our analysis shows that cuts and edits in general elicit early ERP component indicating the registration of syntactic violations as known from language, music, and action processing. However, continuity edits and cuts‐across the line differ from each other regarding later components likely to be indicating the differences in spatial remapping as well as in the degree of conscious awareness of one's own perception. Interestingly, a time–frequency analysis of the occipital alpha rhythm did not support the hypothesis that such differences in processing routes are mainly linked to visual attention. On the contrary, our study found specific modulations of the central mu rhythm ERD as an indicator of sensorimotor activity, suggesting that sensorimotor networks might play an important role. We think that these findings shed new light on current discussions about the role of attention and embodied perception in film perception and should be considered when explaining spectators’ different experience of different kinds of cuts.     

Conditionals As Representative Inferences

According to Adams (Inquiry 8:166–197, 1965), the acceptability of an indicative conditional goes with the conditional probability of the consequent given the antecedent. However, some conditionals seem to be inappropriate, although their corresponding conditional probability is high. These are cases with a missing link between antecedent and consequent. Other conditionals are appropriate even though the conditional probability is low. Finally, we have the so-called biscuit conditionals. In this paper we will generalize analyses of Douven (Synthese 164:19–44, 2008) and others to account for the appropriateness of conditionals in terms of evidential support. Our generalization involves making use of Value, or intensity. We will show how this generalization helps to account for biscuit conditionals and conditional threats and promises. Finally, a link is established between this analysis of conditionals and an analysis of generic sentences.

     

Cognitive determinants of the success of inventors: Complex problem solving and deliberate use of divergent and convergent thinking

With reference to Henderson's (2004) assumption that inventors are “expert problem solvers”, we studied the ability of inventors to solve complex problems (CPS) using a sample of 46 German inventors. The participants had to use FSYS 2.0, a computer-simulated microworld. Additionally, we assessed metacognition, in particular the participants' ability to make deliberate use of divergent and convergent thinking. This ability was expected to be an important skill involved in solving complex problems (Dörner, Kreuzig, Reither, & Stäudel, 1983). We assumed a positive correlation between the individual success of inventors (number of granted and marketed patents) and CPS abilities. Controllability of divergent and convergent thinking turned out to be a predictor of the success of inventors and allowed us to identify the top 10% performers. Oddly however, the best problem solvers were inventors with exactly one granted patent. Data from a posteriori conducted interviews help explaining the results.
