The evolving systems approach to creative work

This study investigated the connection between drawing skill and artistic creativity in relation to age groups and levels of artistic involvement among 223 Chinese primary, secondary, and university students in Hong Kong. Based on the fantasy drawing task, visual-artist judges made expert judgments on students' drawing skill and artistic creativity. There was substantial correlation between drawing skill and artistic creativity among children, adolescents, and young adults, even when artistic involvement was controlled in the partial correlation analyses. The results of correlational and regression analyses suggested that drawing skill contributed most significantly to the prediction of artistic creativity throughout the years at different stages of development, but artistic involvement became more important, especially in young adulthood. Implications of the findings on the skill–creativity relationship for arts education and the directions for future research are discussed.     

Feedback in Response Recognition and Production

The role of feedback in the development of recognition memory was examined by testing pairs of subjects; one subject performed the movement while the other listened to the movement in an adjacent room. Both groups of subjects developed recognition memory during training with KR, and recognition performance was virtually identical for both groups. In addition, previous experience with the sensory consequences of the movement led to improved response production during initial trials. A possible mechanism to account for this finding is proposed. Appreciation is extended to Richard A. Schmidt and Anne Marie Bird for helpful comments in earlier drafts of this paper.     

The Effects of Force and Direction Uncertainty on Choice Reaction Time in an Isometric Force Production Task

The two experiments reported examined the temporal organization of force and direction motor-programming processes in a step-input tracking type task. Both experiments observed a reduction in reaction time in the direction-uncertain conditions compared to the direction-certain ones. Thus it seems as though the direction decision does not have to precede the selection of the proper amount of force. Experiment 2 observed an underadditive interaction between levels of direction uncertainty (certain or uncertain) and levels of force uncertainty (certain or uncertain). This interaction was interpreted as support for a parallel organization of the processes responsible for the programming of force and direction and thus, strongly supports the parallel model of programming recently proposed by Klapp (1977a, b).     

Symmetry, Compact Closure and Dagger Compactness for Categories of Convex Operational Models

In the categorical approach to the foundations of quantum theory, one begins with a symmetric monoidal category, the objects of which represent physical systems, and the morphisms of which represent physical processes. Usually, this category is taken to be at least compact closed, and more often, dagger compact, enforcing a certain self-duality, whereby preparation processes (roughly, states) are interconvertible with processes of registration (roughly, measurement outcomes). This is in contrast to the more concrete “operational” approach, in which the states and measurement outcomes associated with a physical system are represented in terms of what we here call a convex operational model: a certain dual pair of ordered linear spaces–generally, not isomorphic to one another. On the other hand, state spaces for which there is such an isomorphism, which we term weakly self-dual, play an important role in reconstructions of various quantum-information theoretic protocols, including teleportation and ensemble steering. In this paper, we characterize compact closure of symmetric monoidal categories of convex operational models in two ways: as a statement about the existence of teleportation protocols, and as the principle that every process allowed by that theory can be realized as an instance of a remote evaluation protocol—hence, as a form of classical probabilistic conditioning. In a large class of cases, which includes both the classical and quantum cases, the relevant compact closed categories are degenerate, in the weak sense that every object is its own dual. We characterize the dagger-compactness of such a category (with respect to the natural adjoint) in terms of the existence, for each system, of a symmetric bipartite state, the associated conditioning map of which is an isomorphism.     

Emotional Reactions Before Examinations: II. Results of a Questionnaire

To evaluate the effect of session replication and the effect of the duration of the interval between sessions on CFF, three groups different in the methods of spacing sessions were tested for 10 sessions. A significant interaction effect was observed between interval durations and session replications. The group that was tested daily for five consecutive days showed a consistent elevation in threshold after the first two sessions, while the other two groups showed relatively uniform threshold scores over the 10 sessions.     

Overlooking the Obvious: Incentives to Lie

Over the years, people have searched for deception cues in the liar's behavior. However, the sender's incentives to lie might be more revealing than behavior. In Experiment 1, an incentive was developed that was predictive of lying. Judges with access to incentive information in addition to behavior achieved almost perfect lie/truth detection. This was not a result of the speakers' behavior being transparent (Experiment 2) but because incentive information was useful to separate lies from truths (Experiments 2 and 3). Experiment 3 revealed that people may forego perfectly diagnostic contextual cues to base their judgments on illusory behavioral cues.     

Emotional awareness,gender, and peculiar body-related beliefs

Research has broadly established that emotional disturbances are associated with body image disturbances. This is the first study to examine links between facets of emotional awareness and peculiar body-related beliefs (PBB), or beliefs about an imagined or slight defect in one's appearance or bodily functioning. In a sample of college students (n=216), we found that low emotional clarity (the extent to which the type and source of emotions are understood) was associated with higher PBB in both women and men, and the relation between emotional clarity and PBB was further moderated by attention to emotions (the extent to which emotions are attended to) and gender. Men with low attention to emotions and women with high attention to emotions both experienced higher levels of PBB if they also reported low levels of emotional clarity. This interactive effect was not attributable to shared variance with body mass index, neuroticism or affect intensity.     

Examining the contextual and temporal stability of perceptions of emotional utility

The present research examined the degree to which perceptions of emotional utility are stable across contexts and over time. Self-reported perceptions of emotional utility and actual experience of emotion were measured in two samples of college students. In Study 1, participants were presented with two different types of goals (independent vs. interdependent) and were asked to rate the degree to which they found different types of emotions (e.g., appreciation, pride) useful in each context. In Study 2, participants completed daily online questionnaires in which they responded to questions assessing perceptions of emotional utility and actual affect in relation to personal goals. As predicted, across both samples, perceived utility of specific types of emotions was found to be associated with specific types of goals. Importantly, perceived utility of emotion was also found to be a relatively stable individual difference variable, even after taking into account the actual experience of emotion.
