Can clouds dance? Neural correlates of passive conceptual expansion using a metaphor processing task: Implications for creative cognition

Creativity has emerged in the focus of neurocognitive research in the past decade. However, a heterogeneous pattern of brain areas has been implicated as underpinning the neural correlates of creativity. One explanation for these divergent findings lies in the fact that creativity is not usually investigated in terms of its many underlying cognitive processes. The present fMRI study focuses on the neural correlates of conceptual expansion, a central component of all creative processes. The study aims to avoid pitfalls of previous fMRI studies on creativity by employing a novel paradigm. Participants were presented with phrases and made judgments regarding both the unusualness and the appropriateness of the stimuli, corresponding to the two defining criteria of creativity. According to their respective evaluation, three subject-determined experimental conditions were obtained. Phrases judged as both unusual and appropriate were classified as indicating conceptual expansion in participants. The findings reveal the involvement of frontal and temporal regions when engaging in passive conceptual expansion as opposed to the information processing of mere unusualness (novelty) or appropriateness (relevance). Taking this new experimental approach to uncover specific processes involved in creative cognition revealed that frontal and temporal regions known to be involved in semantic cognition and relational reasoning play a role in passive conceptual expansion. Adopting a different vantage point on the investigation of creativity would allow for critical advances in future research on this topic.     

Can clouds dance? Part 2: An ERP investigation of passive conceptual expansion

Conceptual expansion, one of the core operations in creative cognition, was investigated in the present ERP study. An experimental paradigm using novel metaphoric, nonsensical and literal phrases was employed where individual differences in conceptual knowledge organization were accounted for by using participants’ responses to categorize the stimuli to each condition. The categorization was determined by their judgment of the stimuli on the two defining criteria of creativity: unusualness and appropriateness. Phrases judged as unusual and appropriate were of special interest as they are novel and unfamiliar phrases thought to passively induce conceptual expansion. The results showed a graded N400 modulation for phrases judged to be unusual and inappropriate (nonsense) or unusual and appropriate (conceptual expansion, novel metaphorical) relative to usual and appropriate (literal) phrases. The N400 is interpreted as indexing greater effort to retrieve semantic information and integrate the novel concepts presented through the phrases. Analyses of the later time-window showed an ongoing negativity that was graded in the same manner as the N400. The findings attest to the usefulness of investigating creative cognition using event-related electrophysiology.     

Kreuzvalidierung der Kurzform des Kindheitsfragebogens

Objectives

Existing questionnaires about parent-child relationships usually assess love and control only. The childhood questionnaire (CQ) offers a more differentiating alternative.

Methods

In a sample of approximately 1,400 patients and more than 500 controls the CQ was reduced from 22 to 11 scales and the number of items of each scale was shortened to 5.

Results

The shortened scales of the CQ also showed good reliability and item characteristics, as well as plausible intercorrelations.

Conclusion

By the use of 66 out of the former 128 items, the shortened version of the CQ assesses three further important dimensions in the parent-child relationship of adults towards their parents in childhood besides love and control: punishment, ambition and role reversal. Beside this, parental separation, divorce and job status as well as various parameters of the socio-economic status (e.g. educational, occupational and financial) of the parents can be assessed.     

Algorithmic modeling of the irrelevant sound effect (ISE) by the hearing sensation fluctuation strength

Background sounds, such as narration, music with prominent staccato passages, and office noise impair verbal short-term memory even when these sounds are irrelevant. This irrelevant sound effect (ISE) is evoked by so-called changing-state sounds that are characterized by a distinct temporal structure with varying successive auditory-perceptive tokens. However, because of the absence of an appropriate psychoacoustically based instrumental measure, the disturbing impact of a given speech or nonspeech sound could not be predicted until now, but necessitated behavioral testing. Our database for parametric modeling of the ISE included approximately 40 background sounds (e.g., speech, music, tone sequences, office noise, traffic noise) and corresponding performance data that was collected from 70 behavioral measurements of verbal short-term memory. The hearing sensation fluctuation strength was chosen to model the ISE and describes the percept of fluctuations when listening to slowly modulated sounds (f(mod) < 20?Hz). On the basis of the fluctuation strength of background sounds, the algorithm estimated behavioral performance data in 63 of 70 cases within the interquartile ranges. In particular, all real-world sounds were modeled adequately, whereas the algorithm overestimated the (non-)disturbance impact of synthetic steady-state sounds that were constituted by a repeated vowel or tone. Implications of the algorithm's strengths and prediction errors are discussed.     

Bottom-up and top-down dynamics in young children's executive function: Labels aid 3-year-olds’ performance on the Dimensional Change Card Sort

Executive function (EF) improves between the ages of 3 and 5 and has been assessed reliably using the Dimensional Change Card Sort (DCCS), a task in which children first sort bivalent cards by one dimension (e.g., shape) and then are instructed to sort by a different dimension (e.g., color). Three-year-olds typically perseverate on the pre-switch dimension, whereas 5-year-olds switch flexibly. Labeling task stimuli can facilitate EF performance (0110 and 0060), but the nature of this effect is unclear. In 3 experiments we examined 2 hypotheses deriving from different theoretical perspectives: first, that labels facilitate performance in a more bottom-up fashion, by biasing attention to relevant task rules (Kirkham et al., 2003); and second, that labels aid performance in a more top-down fashion by prompting reflection and an understanding of the hierarchical nature of the task (Zelazo, 2004). Children performed better on the DCCS when labels referred to the relevant sorting dimension (Experiment 1). This was a function of the content of the labels rather than the change in auditory signal across phases (Experiment 2). Furthermore, labeling the opposite dimension only did not have a symmetrically negative effect on performance (Experiment 3). Together, these results suggest external, verbal labels bias children to attend to task-relevant information, likely through interaction with emerging top-down, endogenous control.     

Hating the cute kitten or loving the aggressive pit-bull: EC effects depend on CS–US relations

Evaluative conditioning (EC) refers to valence changes of initially neutral stimuli (CSs) through repeated pairings with positive or negative stimuli (USs). The current study is about the moderating role of qualifiers that specify the CS–US relation during these pairings. We show successful EC with pictures of men (CSs) and of liked/disliked animals or landscapes (USs). More importantly, the same pairings resulted in standard and reversed EC effects depending on semantic qualifier of the CS–US relation. CSs loving positive (negative) USs became more positive (negative), while CSs loathing positive (negative) USs became more negative (positive). These data favour a propositional EC account (De Houwer, 2009) over a purely associative account, as they show that it is not only relevant that CS and US are related, but how they are related.     

Emotion-induced modulation of recognition memory decisions in a Go/NoGo task: Response bias or memory bias?

In recognition memory tests for words, items with negative emotional meaning are more often classified as “old” compared to neutral items, whether or not they are in fact old. Two accounts for this bias have been offered: One proposes that emotions disrupt retrieval and response monitoring processes (executive control account), the other proposes that emotions cause illusory feelings of remembering (memory bias account). We addressed this issue by varying the target signal in a Go/NoGo variant of a recognition memory task for negative, neutral, and positive words and faces: One group of participants was asked to respond to old items whereas the other group was asked to respond to new items. Results showed that the “Go-for-old” group showed the typical emotion-induced response bias shift for both positive and negative words, while the “Go-for-new” group showed the opposite pattern. Results were nonsignificant for faces, but went into the same direction. The findings are clearly inconsistent with the executive control account and speak for a genuine memory illusion induced by emotional arousal.     

Towards a Marine Mindset: Visiting an Aquarium Can Improve Attitudes and Intentions Regarding Marine Sustainability

ABSTRACT

The oceans are crucial for human survival, yet they are under serious threat from humans, for example through overfishing and poor waste management. We investigated two questions. First, does a leisure visit to an aquarium improve visitor attitudes and intentions towards marine sustainability, specifically regarding overfishing and pollution? Second, does an information booklet handed out in addition to the visit have additional measurable impact? Aquarium visitors (n = 104) completed a questionnaire on marine sustainability attitudes and behavioral intentions before and after their visit. Half of the visitors also were given informational materials that offered behavioral solutions to the problem of overfishing. The aquarium visit significantly improved visitors’ overall attitudes and intentions. The information booklet additionally improved intentions significantly, but not attitudes. These findings show that a visit to an aquarium can help individuals develop what we term a marine mindset, a state of readiness to address marine sustainability issues. Implications, limitations, and ideas for further research are discussed.     

There is more than obeying display rules: Service employees’ motives for emotion regulation in customer interactions

Although research has focused on how service employees regulate their emotions, few studies have explored why they do so. In this article, we first described which kinds of motives for emotion regulation exist in customer interactions. Second, we investigated how the motives are related to four emotion regulation strategies. The application of an explorative approach resulted in a list of 10 motives, which could be classified into the three motive categories: pleasure, prevention, and instrumental. Hierarchical linear modelling of 421 reported service interactions from a diary study revealed that the motive categories were differently related to the emotion regulation strategies. Motives of the instrumental category were only significantly positively related to surface acting. Motives of the pleasure category were positively related to deep acting and automatic regulation as well as negatively related to surface acting and emotional deviance. Motives of the prevention category were positively related to deep acting, surface acting, and emotional deviance as well as negatively related to automatic regulation. These results can be used by organizations not only to enhance the motivation of employees towards emotion regulation, but also towards more authentic emotional expressions.
