Film-induced negative affect triggers overeating in restrained eaters

We tested the effects of film-induced negative affect (i.e., exposure to a frightening film) in 60 women classified as either restrained or unrestrained eaters on the basis of their responses to the Revised Restraint Scale (Herman & Polivy, 1980). Exposure to the frightening film, in contrast to a neutral film, was associated with increases in anxiety, sadness, and anger. High restraint subjects exposed to the frightening film ate more than did equally restrained subjects exposed to a neutral film or low restraint subjects exposed to either film. Thus, negative affect triggered overeating among restrained eaters. Although unrestrained eaters exposed to the frightening film ate less than those who viewed the neutral film, this difference was not statistically significant. These results suggest that negative affect may prompt overeating in persons who attempt to restrict their caloric intake.     

Flexibility, inhibition, and planning: frontal dysfunctioning in schizophrenia

Neuropsychological tests known to reveal abnormalities in patients with frontal lobe damage were used to explore cognitive function in 20 chronic schizophrenic patients. Eleven control subjects, matched on age and NLV-IQ (NLV is the Dutch version of the NART) were also tested. No impairments of planning ability were found on either the Action Program test or the Zoomap test, both subtests from the BADS (Behavioural Assessment of the Dysexecutive Syndrome). No abnormalities were apparent on tests of reactive flexibility, measured by task-switching and by the Rule Shift Cards test, also a subtest of the BADS. Patients with schizophrenia, however, had significantly greater difficulty in inhibiting irrelevant information and in generating words in a verbal fluency task, a measure of spontaneous flexibility.     

The Illusion-of-Transparency and Episodic Memory: Are People Egocentric or Do People Think that Lies are Easy to Detect?

The illusion-of-transparency seems like an egocentric bias, in which people believe that their inner feelings, thoughts and perspectives are more apparent to others than they actually are. In Experiment 1, participants read out true and false episodic memories to an audience. Participants over-estimated the number of people who would think that they were the liar, and they overestimated how many would correctly identify the liar. Experiment 2 found that with lessened task demands, and by using a scale of doubt, participants distinguished lies from truthful statements (albeit with a degree of error). Over the two experiments, results indicated that people have some ability to distinguish lies from truth (in illusion-of-transparency tasks), although people often overestimate this ability, and participants sometimes think their own lies are easier to detect than is really the case.     

Mechanisms of motivation–cognition interaction: challenges and opportunities

Recent years have seen a rejuvenation of interest in studies of motivation–cognition interactions arising from many different areas of psychology and neuroscience. The present issue of Cognitive, Affective, & Behavioral Neuroscience provides a sampling of some of the latest research from a number of these different areas. In this introductory article, we provide an overview of the current state of the field, in terms of key research developments and candidate neural mechanisms receiving focused investigation as potential sources of motivation–cognition interaction. However, our primary goal is conceptual: to highlight the distinct perspectives taken by different research areas, in terms of how motivation is defined, the relevant dimensions and dissociations that are emphasized, and the theoretical questions being targeted. Together, these distinctions present both challenges and opportunities for efforts aiming toward a more unified and cross-disciplinary approach. We identify a set of pressing research questions calling for this sort of cross-disciplinary approach, with the explicit goal of encouraging integrative and collaborative investigations directed toward them.     

Cognitive styles and person–environment fit: Investigating the consequences of cognitive (mis)fit

There is currently considerable interest in the key elements of person–environment fit to understand vocational behaviour and to develop strategic human resource management practices. In the light of this interest, we wanted to investigate (1) whether people within similar functions have similar cognitive styles, and (2) what the consequences of cognitive (mis)fit are on three work attitudes, using two large-scale databases (N = 24,267 and N = 2,182). We identified a knowing-oriented cognitive climate in finance, information technology (IT), and research and development (R&D) functions; a planning-oriented cognitive climate in administrative and technical and production functions; and a creating-oriented cognitive climate in sales and marketing functions and general management. Furthermore, we found that the relationship between people's cognitive styles and work attitudes (i.e., job satisfaction, job search behaviour, and intention to leave) does not depend on the cognitive climate in which they work. However, we did find that people with a higher creating style on average score higher on intention to leave and job search behaviour in comparison with people who score lower on the creating style, irrespective of the cognitive climate they are working in. The cognitive climate also partially affects job satisfaction and intention to leave after controlling for cognitive styles. In summary, cognitive styles and cognitive climate seem to have separate influences on people's work attitudes. Our findings are relevant for selection and recruitment policies of organizations and in the context of training, job design, and workforce planning.     

Methodological practices in cognitive style research: Insights and recommendations from the field of business and psychology

This study provides insights and recommendations concerning methodological practices of cognitive style research applied to the field of business and psychology. Based on a carefully designed selection process, 139 style-related articles published between 1986 and 2010 were content-analysed. In terms of research design, we found the field to be dominated by quantitative, cross-sectional, and single-source designs that relied heavily on self-reports, sample surveys, and student samples. While this might indicate a potential vulnerability in terms of internal and external validity, a strong emphasis on construct validity was also found, exemplified by high attention to reliability, and exploratory and confirmatory factor analyses. With regard to construct measurement, although more than 30 different instruments were used, the field was dominated by three of these. Regarding data analysis, traditional approaches have been mainly used and more advanced and novel approaches have not yet permeated through the cognitive style field. Implications and suggestions for future research are offered. This is the first review of methodological practices in cognitive style research and represents an important step in the advancement of the field.     

Adolescent Egocentrism and the Illusion of Transparency: Are Adolescents as Egocentric as we Might Think?

The illusion of transparency, or people’s tendency to believe their thoughts and feelings as more apparent to others than they actually are, was used to investigate adolescent egocentrism. Contrary to previous research demonstrating heightened adolescent egocentrism, adolescents exhibited similar levels of egocentrism to adults. In experiment 1, 13-14 year-olds and adult participants both truthfully described and lied about a series of pictures. Both adolescent and adult liars indicated that they were more confident that other participants would know when they were lying, than other participants actually indicated. In experiment 2, 13-14 year-olds, 15-16 year-olds and adult participants read to an audience. The illusion of transparency effect manifested itself differently according to gender: Female participants indicating that they looked more nervous than audiences thought, whilst male participants indicating that they were more entertaining than audiences thought. Results were interpreted using simulation theory, and suggested that adolescents might not be as egocentric as previously thought.     

Classifying postures of freely moving rodents with the help of fourier descriptors and a neural network

A computerized method for classifying the postures of freely moving rodents is presented. The behavior of the rats was recorded on videotape by means of a camera hanging perpendicular to an open field. An automatic tracking system (10 images/sec) was used to transform the video images of postures into a binary image, thereby providing silhouettes in a computer format. The contours of these silhouettes were used for determining their characteristic features with the help of a Fourier transformation. The resulting features were classified with the help of a Kohonen network composed of 32 neurons. The four bestwinning neurons, rather than the usual one, were used for the classification. The resolution (11,090 distinct classes of postures), reliability (96.9%), and validity of this method were determined. With the use of the same approach, the effectiveness of this method for classifying behaviors was illustrated by analyzing grooming (247 grooming images vs. 4,950 nongrooming images). We found 15.4% false positives and 2.5% false negatives.     

Development and validation of the cognitive style indicator

The authors describe the development and validation of the Cognitive Style Indicator (CoSI) using 3 diverse samples (N = 5,924; N = 1,580; and N = 635). Reliability, item, and factor analyses demonstrated the internal consistency and homogeneity of 3 cognitive styles: knowing, planning, and creating. The authors also found substantial support for the instrument's convergent and discriminant validity by including other cognitive style instruments and personality and academic performance measures in the validation process. Criterion-related validity was confirmed by examination of the relation between these cognitive styles and work-related characteristics. The main contributions of this study are (a) the further refinement of the analytic-intuitive cognitive style dimension by splitting the analytic pole in a knowing and a planning style and (b) the development of a valid and reliable cognitive style instrument for use in organizations.
