The creative thinking and ego functioning of children

Abstract:

One hundred highly creative children and 100 uncreative children were selected from a sample of 1,450 fifth‐ and sixth‐grade children. They were identified with the the Torrance Tests of Creative Thinking (TTCT). Comparisons revealed significant differences in terms of quantity and quality of primary process content. The creative children gave not only more primary process ideation, but the quality was (a) significantly more libidinal than aggressive, (b) more regressive (greater DD), and (c) showed more effective use of regression in the service of the ego (calculated by using the popular response to score defense effectiveness). There were no sex differences in the TTCT scores or the primary process content, but girls gave more libidinal content and boys gave more aggressive content.     

Similarity and multidimensional ratio estimation with simultaneous qualitative and quantitative variation

Abstract.— Previous work on content models of multidimensional similarity have mostly been concerned with the case of only qualitative variation. In this study a set of emotion words that varied both in content and intensity was used as stimuli. Subjects gave multidimensional ratio estimations, similarity estimations and also unidimensional ratings of intensity. Both individual data and group data were collected. Five different previously suggested content models of similarity failed to fit these data that showed large individual idiosyncratic variability. It is pointed out that previous work, where some of the models fitted rather well, was concerned with cases that were largely insensitive to deviations fram the models.     

Art, authenticity and appropriation

It is often suggested that artists from one culture (outsiders) cannot successfully employ styles, stories, motifs and other artistic content developed in the context of another culture. I call this suggestion the aesthetic handicap thesis and argue against it. Cultural appropriation can result in works of high aesthetic value. While in China as a visiting scholar in the Department of Philosophy of Beijing Normal University, I gave a series of lectures at leading Chinese universities. This essay is based on a lecture that I gave at Renmin University of China on 17 April 2006.     

条件推理:“演绎”与“概率”两种实验研究范式之比较

本研究通过推理心理学研究中的“演绎”和“概率”两种实验范式设计对同一个班级的大学生参与者(实验一中N=57,实验二中N=43)进行先后两次有关条件推理的实验研究后,得出如下主要结果:(1)推理者在对不同的“纯形式条件命题本身的认可度”以及对由它们各自建构的同类型推理题的推理结果之间的作答反应模式之间的差异都很小且具有较高的一致性;(2)对由不同的“含具体内容的假言命题”本身的认可度之间以及由它们建构的同类型条件推理题的推理结果之间具有较大的差异性;(3)推理者对“演绎”和“概率”两种不同实验范式分别建构的内容近似的推进题进行推理时具有大致相同的作答反应趋势。由此可以推论推理者在“概率推理实验范式”中的作答或推理结果可以被视为只是对“演绎推理实验范式”的相应推理题给出“概率解”的心理加工过程。     

A rationale for minimizing distortion in personality questionnaire keys

A rationale and a procedure for constructing questionnaire keys so as to minimize the effect of distortion or faking by the respondents is developed. This rationale is based on the supposition that suppressor items can be identified to reduce distortion in, and thus add to, the validity of questionnaire keys. The procedure is designed primarily for application to the construction of forced choice items.The results of an empirical test of the efficicacy of the forced choice pairing procedure developed as a consequence of this rationale are presented. A key based on forced choice pairs developed by this procedure gave a validity of .33; a second key based on forced choice pairs developed by more conventional procedures gave a validity of .23.The opinions expressed are those of the author and are not to be construed as reflecting official Department of the Army policy. The rationale presented herein was developed and used in an Army research program concerned with the selection of ROTC cadets. In substance, the content of this paper is contained in PRS Report 868,A rationale for minimizing distortion in personality questionnaire keys.     

Style follows content: on the microgenesis of art perception

Despite fruitful research in experimental aesthetics, the dynamics of aesthetics, i.e., the processes involved in art perception, have received little attention. Concerning representational art, two aspects seem most important in this respect: style and content. In two experiments, we examined the dynamics of processing of style and content by means of the microgenetic approach. This approach systematically varies perceptual conditions to find out about the stages involved in the formation of percepts – their microgenesis. Participants gave similarity ratings for pairs of pictures that were fully crossed in style (artist) and content (motif). Presentation times were systematically varied between 10, 50, 202 and 3000 ms (Experiment 1) plus unlimited presentation time (Experiment 2). While effects of content were present at all presentation times, effects of style were traceable from 50 ms onwards. The results show clear differences in the microgenesis of style and content, suggesting that in art perception style follows content.     

Judgment of the credibility of rape allegations: a content analytic field experiment]

This study explores the issue of whether allegations of rape can be correctly identified as true or false on the basis of a set of content criteria used successfully in previous studies with respect to children's accounts of sexual abuse. A sample of 30 authentic protocols of police interrogations of women reporting rape were selected for the study. Fifteen cases were classified as false accounts because the complaints eventually confessed to having fabricated their allegations. The remaining cases were classified as true rapes on the basis of medical and other corroborating evidence. A group of experienced police officers (N = 30) judged these cases in terms of their credibility on the basis of the 19 content criteria suggested by Steller & K?hnken (1989) and gave an overall judgment of the true vs. false nature of each statement. A second group of police officers (N = 22) judged the credibility of the statements without reference to these criteria. The findings from a series of discriminant function analyses showed that the set of criteria as a whole is successful in distinguishing between true and false rape allegations. The results of the stepwise discriminant function analyses reveal which criteria in particular contribute to the correct identification of true and false cases. However, the higher percentage of correct classifications in the group using the content criteria was only marginally significant compared to the second group judging the cases without reference to the criteria. Altogether, the findings of this study support the basic tenet of statement analysis that the linguistic features of a statement contain essential clues for assessing its credibility.     

Beyond the answer: post-error processes

When you suspect that you just gave an erroneous answer to a question you stop and rethink. Suspected errors lead to a shift in the control and content of cognitive processes. In the present experiment we investigated the influence of errors upon heart rates and response latencies. Sixty-four subjects participated in an experiment in which each subject solved a sequence of 60 verbal analogies. The results demonstrated increased latencies after errors and decelerated heart rates during the post-error period. The results were explained by a psychophysiological model in which the septo-hippocampal system functions as a control system which coordinates the priority and selection of cognitive processes. Error detection suppresses strategies which otherwise prevent looping and iterative reanalyses of old material. The inhibition is also responsible for the cardiac slowing during the post-error period.     

Children’s prayers from a Hospital Chapel

Children’s prayers, from prayer books left in the Chapel of a Children’s Hospital between 1998 and 2002, were studied for what the children’s God-talk would reveal about their perceptions of God. Of the 3893 prayers written during this period, 346 were confidently identified as being authored by children. The sample of 346 prayers, which gave rise to 558 expressions of prayer, was explored through a content analysis, used quantitatively to summarise and describe the data, and a thematic analysis, informed by methods from Grounded Theory. The psychological and spiritual significance of the prayers is drawn out, demonstrating the richness and relationality of children’s spirituality. The predominance of prayers written by female writers, suggests that the extent to which relationality is present is related to gender. Questions concerning possible gender-related differences in girls’ and boys’ spirituality are raised and implications for practice are considered.     

What matters is the underlying experience: Similar motor responses during processing observed hand actions and hand-related verbs

It is well-accepted that processing observed actions involves at some extent the same neural mechanisms responsible for action execution. More recently, it has been forwarded that also the processing of verbs expressing a specific motor content is subserved by the neural mechanisms allowing individuals to perform the content expressed by that linguistic material. This view is also known as embodiment and contrasts with a more classical approach to language processing that considers it as amodal. In the present study, we used a go/no-go paradigm, in which participants were requested to respond to real words and pictures and refrain from responding when presented stimuli were pseudowords and scrambled images. Real stimuli included pictures depicting hand- and foot-related actions and verbs expressing hand- and foot-related actions. We, therefore, directly compared the modulation of hand motor responses during the observation of actions and the presentation of verbs, expressing actions in the same category. The results have shown that participants gave slower hand motor responses during the observation of hand actions and the processing of hand-related verbs as than observed foot actions and related verbs. These findings support embodiment showing that whatever the modality of presentation (observed action or verb), the modulation of hand motor responses was similar, thus suggesting that processing seen actions and related verbs shares common mechanisms most likely involving the motor system and the underlying motor experience.     

Cold and lonely: does social exclusion literally feel cold?

Metaphors such as icy stare depict social exclusion using cold-related concepts; they are not to be taken literally and certainly do not imply reduced temperature. Two experiments, however, revealed that social exclusion literally feels cold. Experiment 1 found that participants who recalled a social exclusion experience gave lower estimates of room temperature than did participants who recalled an inclusion experience. In Experiment 2, social exclusion was directly induced through an on-line virtual interaction, and participants who were excluded reported greater desire for warm food and drink than did participants who were included. These findings are consistent with the embodied view of cognition and support the notion that social perception involves physical and perceptual content. The psychological experience of coldness not only aids understanding of social interaction, but also is an integral part of the experience of social exclusion.     

Electrocutaneous stimulation L The effects of stimulus parameters on absolute threshold

Thresholds for detecting electrical stimulation were measured as a function of (1) body locus, (2) electrode configuration, (3) stimulus waveform, and (4) pulse duration. The results were: (1) the forehead gave slightly, but not reliably, lower thresholds than the abdomen; (2) concentric electrodes gave slightly, but not reliably, lower thresholds than unifocal electrodes; (3) cathodal monophasic (?) pulses and biphasic pulses (+/? and ?/+) gave identical thresholds, while anodal monophasic (+) pulses gave higher thresholds; and (4) thresholds decreased as pulse duration increased up to .5 msec, but changed less with longer pulses.     

Can attention give a left-ear advantage for verbal stimuli?

Three independent groups of 8 subjects listened monaurally to a randomized list of 50 common and 50 rare words and responded ‘yes’ to rare words. Responses were analyzed for correct identifications of rare words. A 50:50 group heard an equal number of words in right and left ears and gave a small but non-significant right-ear superiority. A 66:34 group heard nearly twice as many words in the right ear as the left and gave a significant right-ear superiority. A 34:66 group heard nearly twice as many words in the left ear as the right and gave a significant left-ear superiority. Responses were also analyzed according to signal-detection theory. Implications are discussed for theories of ear advantages.     

The transcendentals in the middle ages: An introduction

Although most predicates may be truthfully predicated of only some beings, there are others that seem to apply to every being. The latter, including being itself, were known as the transcendentals in the Middle Ages and gave rise to the much disputed doctrine of the transcendentals. This article explores the main tenets of the doctrine and the difficulties that they face, the reasons why scholastic authors were interested in these issues, and the origins of the doctrine.I am grateful to Jan Aertsen, Kenneth Barber, Michael Gorman, and Scott MacDonald for their suggestions concerning this paper.     

Electrophysiological correlates of encoding and retrieving emotional events

This study examined the impact of emotional content on encoding and retrieval processes. Event-related potentials were recorded in a source recognition memory task. During encoding, a posterior positivity for positive and negative pictures (250-450 ms) that presumably reflects attentional capturing of emotionally valenced stimuli was found. Additionally, positive events, which were also rated as less arousing than negative events, gave rise to anterior and posterior slow wave activity as compared with neutral and negative events and also showed enhanced recognition memory. It is assumed that positive low-arousing events enter controlled and elaborated encoding processes that are beneficial for recognition memory performance. The high arousal of negative events may interfere with controlled encoding mechanisms and attenuate item recognition and the quality of remembering. Moreover, topographically distinct late posterior negativities were obtained for the retrieval of the context features location and time that support the view that this component reflects processes in service of reconstructing the study episode by binding together contextual details with an item and that varies with the kind of episodic detail to be retrieved.     

Teachers' task demands,students' test expectations,and actual test content

Background: Previous studies on instructional importance show that individual students and their teachers differ in the topics that they consider important in the context of an upcoming teacher‐made test. Aims: This study aimed to examine whether such differences between students' test expectations and teachers' intended task demands can be explained by the actual test content. Samples: Participants were history teachers (N=19) and their 11th‐grade students (N=388). Method: Teachers and students rated the importance of text sections that would be tested in the near future. By means of multilevel analysis, ratings were compared with the occurrence of sections in the tests. Results: Although teachers considered a majority of sections as important and tested only a minority of the sections, their tests still included sections rated as unimportant. The number of such discrepancies, however, was relatively small. Sections the teachers rated important had a much higher probability of being included in the test than sections rated unimportant. For students, a similar but lower degree of correspondence between ratings and test content was found. Interestingly, for sections that teachers considered important, students more often gave a higher rating when these sections appeared in the test than when they did not. The same holds for sections that teachers considered unimportant. Conclusions: For both teachers and students there is a limited correspondence between perceived task demands and test content. Furthermore, students' perceptions of task demands show a compensation for some of the differences between their teachers' intended task demands and the test demands.     

Women's knowledge of prenatal ultrasound and informed choice

This study evaluated women's understanding of prenatal ultrasound in terms of meeting the requirements for informed choice. A cross-sectional survey was conducted to evaluate (1) how information is provided, (2) women's perceived value of the information received and, (3) their understanding of ultrasound in relation to the principles of informed choice. Women (n = 113) completed a questionnaire prior to their 18-week ultrasound. Fifty-five percent stated they received no information from their care provider. Only 31.9% considered health care providers as a very helpful source of information. Yet, 69.0% stated their care provider gave them information that facilitated their understanding. Gaps were identified in women's understanding of ultrasound. Specifically, 46.0% did not view ultrasound as a screen for anomalies; some were uncertain about the safety (18.6%), diagnostic capabilities (26.5%), and limitations of testing (37.2%). These results suggest that women's understanding of ultrasound does not meet the requirements of informed choice.
