Exploring the Effects of Creativity Training on Creative Performance and Creative Self‐Efficacy: Evidence from a Longitudinal Study

In organizations and educational institutions, creativity trainings are the preferred approach to enhancing individual creative abilities. However, three issues regarding these trainings still remain largely unsolved. First, the question of how long‐lasting creativity training effects are has not been sufficiently answered so far. Second, the question arises whether all participants benefit from such trainings equally in terms of their creative performance (CP). Third, an increasing number of studies have shown that creativity trainings may also be able to increase participants' creative self‐efficacy (CSE), that is, the confidence in one's own creativity. Other studies, however, did not find evidence for this effect. Therefore, this article aims to address these issues by analyzing data from three measurement waves. Results reveal that participants' CP increased during the training and decreased only slightly 4 weeks after the training. Additionally, we found an effect of diminishing training returns in that the higher a participant's CP before the training the lower the training effect was. In contrast to most prior literature, we found no support for an effect of creativity training on participants' CSE. We discuss these findings and offer implications for both theory and practice. Finally, we state this study's limitations and derive avenues for further research.     

The Rawdon-Smith illusion

A loudness illusion is described which was originally reported by Rawdon-Smith and Grindley (1935). It is analogous to the Craik-O’Brien-Cornsweet brightness illusion. Procedures are described for generating and measuring the size of the effect, and data are presented showing factors that influence its magnitude. Other examples are discussed that suggest that this effect is a very general phenomenon.     

Cervical Amipaque myelography with lateral C1/C2 puncture with a conventional fluoroscopy device

The paper presents a method of carrying out cervical myelography by lateral C1/C2-puncture (LCP) using a conventional fluoroscopic device with an image-intensifying TV-chain. The patient is deposited on a specially designed transverse table. The amount of time and picture-quality are equale to those for costly special apparatus.     

On-task distractors associated with totball baseball games: a preliminary study

Two totball baseball leagues in southern Louisiana were monitored to judge what type of parental involvement yielded the highest on-task behaviors among participants. 39 children ages 3 to 5 years participated in 3- or 4-inning baseball games with parents on the field. In the Parent on Bases League, a parent stood on first, second, and third base only. In the Parent with Every Child League, a parent stood next to every child on the field. Children were observed on the field at three different dates at 1-min. intervals during the first two innings of one game in both leagues. On-task behaviors were defined as standing in the correct field position and watching the ball. Off-task behaviors consisted of sitting, rolling on the field, talking to a coach or parent, and not watching the ball. A statistically significant difference in the percent of time children spent on-task favored the Parents on Bases League (75.7) versus the other league (50.3). Having fewer parents on the field in these baseball games kept players on-task more effectively than having a parent with each child.     

Morbidity rate in delirium tremens

On evaluating an analysis of 105 cases of delirium tremens over a period of five years in a psychiatric base-unit, the following findings were obtained: Delirium tremens, particularly in conjunction with secondary diseases, constitutes a life-endangering medical emergency and requires intensive medical treatment. Letality was 8,57%. The morbidity-rate and the relapse-rate showed a clearly marked increase; the age of contracting the disease had its frequency peak between 30 and forty, i. e. earlier than in many other statistical surveys. Epileptic attacks as symptoms starting off or accompanying delirium occurred in almost one third of our delirium patients. The impact which these attacks have on the development in the course of process-like alcoholism was discussed.     

A comparison of method-of-adjustment and forced-choice procedures in frequency discrimination

Reported estimates of the frequency difference limen (DL) for tones show considerable variability. To determine the extent that the differences are dependent on psychophysical method, three estimates of the DL at 1,000 Hz were obtained from the same subjects for each of three psychophysical procedures. The three estimates were: (1) the standard deviation of final settings in a methbd of adjustment, (2) the average of several reversals in an adaptive two-interval forced-choice procedure, and (3) the 76%-correct point in a two-interval forced-choice procedure using constant stimuli. The two forced-choice procedures yielded very similar DLs. The adjustment procedure yielded significantly smaller estimates. Possible reasons for the different values produced by adjustment procedures and the nature of the underlying decision process are discussed.     

When the half-full glass is appraised as half empty and memorised as completely empty: Mood-congruent true and false recognition in depression is modulated by salience

Since the 1980s a large body of empirical effort has been devoted to mood-congruent memory (MCM) biases in clinical depression. Whereas there is broad, albeit not unequivocal, evidence that depressive patients retain negative-valenced memory items better than neutral material, few studies have investigated false memories in depression. In a pilot study we gathered support for both enhanced true and false memory for emotional material in depression. The present study aimed to extend these preliminary findings. In view of investigations suggesting that arousing and meaningful stimuli have facilitated access to memory, personal salience was considered a moderator for MCM. In the present study 21 depressed and 22 healthy participants were presented six false memory lists dealing with neutral, negative, and positive themes. At recognition, each item had to be appraised for its degree of valence subsequent to an old–new judgement. Pre-categorised and subjective valence did not discriminate groups. However, relative to controls depressed patients showed both more veridical as well as false recognition for items that concurrently elicited higher salience ratings in patients. In contrast, group differences in recognition performance did not significantly affect salience ratings. Results indicate that salience modulates MCM and may account for discrepancies in the literature.     

Aus vier mach zwei

Background

The diagnostic and statistical manual of mental disorders 5 (DSM-5) includes a revision of the DSM-IV criteria for somatoform disorders. The aim of the current work was to investigate whether (a) patients with DSM-IV diagnoses of somatization disorder, pain disorder and hypochondriasis and (b) whether patients categorized as having the DSM-5 somatic symptom disorder and illness anxiety disorder differ with respect to illness anxiety and cognition regarding somatic symptoms.

Material and methods

The data from 269 inpatients from the psychosomatic clinic Schön Klinik Bad Bramstedt were used. Somatoform disorders were diagnosed using the German version of the structured clinical interview for DSM-IV (SCID).

Results

Patients with a DSM-IV diagnosis of hypochondriasis differed in illness anxiety and catastrophizing interpretation of somatic symptoms compared to patients with other somatoform disorders. Patients with illness anxiety disorder differed in the catastrophizing interpretation of physical symptoms, autonomic sensations, bodily weakness and intolerance of physical complaints compared to patients with somatic symptom disorder.

Conclusion

The present results indicate that illness anxiety and a catastrophizing interpretation of somatic symptoms play a fundamental role in patients with somatoform disorders. Therefore, psychotherapy should address illness anxiety and health-related concerns in all patients with somatoform disorders.
