Concurrent Validity Studies of the Facial Discrimination Task

We examined the concurrent validity properties of the Facial Discrimination Task (FDT), an instrument for the assessment of facial emotion recognition by comparing it with the widely used Pictures of Facial Affect (PFA). In Study 1, 100 adults with heterogeneous psychiatric diagnoses were administered items of the FDT Emotion Task, the FDT Age Task, and PFA. In Study 2, 25 normally developing preschool children were instructed to label happy, sad, or neutral facial expressions from the FDT and the PFA. Despite methodological differences between the two studies, very similar and high correlations were found between the FDT and the PFA overall correct scores (r = .79 and r = .77, respectively). The data suggest that the FDT and the PFA measure similar competencies in preschoolers and in adults with psychiatric disorders. This finding is important because it establishes the concurrent validity of the FDT in child and adult populations.     

Self-injurious behavior in institutionalized,severely/profoundly retarded adults—Prevalence data and staff agreement

Staff agreement on the identification of 18 different types of self-injurious behavior (SIB) and the prevalence of SIB were assessed in a population of 91 severely and profoundly retarded residents in a large facility for mentally retarded people in West Germany (FRG). The survey included 27 direct care staff; groups of three to five rated the behavior of 8 to 27 residents from their own wards. Agreement was calculated with two different formulas for multiple raters. The data suggest that the standard definition of SIB [Tate, B. G.,& Baroff, G. S. (1966).Behavior Research and Therapy, 4, 281–287], together with a list of the most common SIB topographies, yields variable and generally low staff agreement. The data for the prevalence statistics were derived from cases in which at least 50% of the staff had indicated the occurrence of an SIB topography in a resident. Sixty of the 91 residents exhibited some form of SIB; of these, 15 demonstrated only one type, 12 two, and 33 three or more SIB topographies. The data corroborate the notion of the two taxonomic classes of social and nonsocial SIB. Contrary to other classifications the data indicate that ruminative vomiting belongs to the social SIB class.The author wishes to express his gratitude to Dr. Udo Lück, chief psychologist of the Diakoniezentrum Hephata, who made this study possible by his interest and support. The help of Walter Edlinger in collecting the data and of Prof. Hartmann Scheiblechner in giving methodological advice is also greatly appreciated.     

Toward an empirically based parameter selection for time-sampling observation systems

The measurement error of time-sampling observation systems, used to estimate the frequencyof behavioral events, was analyzed by means of a five-factor design, computer simulation experiment. The first three factors represented response parameters: the relative frequency and duration of the behavior and the pattern of response distribution. For each combination of frequency, pattern, and duration, five simulated behavior events were generated within a simulated observation period of 900 sec. A total of 21 different time-sampling systems was employed. As a fourth factor three different observe and record lengths were included (6, 12, and 60 sec). In addition, there were seven different ratios of “observe” to “record” interval length (5∶1, 3∶1, 2∶1, 1∶1, 1∶2, 1∶3, and 1∶5) representing the fifth factor. Thus, 21 time-sampling systems scanned a total of 120 different behavior simulations from 24 types of behavior parameter combinations. The data were analyzed by means of a five-factor (2 × 3 × 4 × 3 × 7) analysis of variance with repeated measures on two factors. The study demonstrated that time sampling leads to high average measurement errors, which are determined by complex interrelationships among a variety of variables. Choosing a time-sampling system arbitrarily may lead to highly erroneous data. It was also shown, however, that time-sampling systems have the potential to yield very accurate results. An empirical selection procedure for time-sampling intervals is proposed to minimize measurement error. Exemplary tables are presented from which time-sampling parameters can be chosen given that the rate, duration, and pattern of occurrence of a behavior to be observed are known.     

Antecedents and Consequences of Adult Play in Romantic Relationships

This study introduces and reports an initial test of a theoretical model of play in romantic relationships. It was hypothesized that self–esteem and humor orientation would be positively associated with playfulness in romantic relationships. Playfulness in romantic relationships was predicted to be positively associated with the experience of positive emotion. Positive emotion, in turn, was predicted to be associated with relationship satisfaction. A self–report instrument was administered to students and community members via snowball sampling. Path analysis revealed that the data were consistent with the proposed model.     

Consumer acceptance of innovations in food: A survey among Polish consumers

The aim of the study was to examine the possible factors that might contribute to consumer acceptance of food innovations. Particular attention was paid to 3 main factors: (a) relationship between socio‐demographic determinants and level of consumer innovation, (b) evaluation of consumer innovation acceptance, particularly toward animal‐derived food products, and (c) consumer preferences for health‐promoting food innovation over time. Studies were conducted using quantitative research methods in 2004 and 2011. An organic method of production, least important in 2004, was top rated in 2011, and ease of preparation dropped to the bottom of the list in 2011, whereas food origin, low fat, and sugar content were ranked in the first group of the considered factors in 2011. Since 2004, consumers have become used to products with various innovations. The new generation of Poles is relatively more open to new food products, due to the wide range of food products available on the free market. Furthermore, the group of well‐educated consumers with a higher level of income has increased in size, and this includes people interested in knowledge of a product's nutritional value and its health impact. Our study extends existing research in the area of understanding consumer expectations toward food innovations. The results not only contribute to the field of consumer behavior but also have practical potential for food market applications, especially for companies operating on or planning to enter the Polish food market, and which could be used for developing communication strategies.     

Dissociable contributions of the left and right posterior medial orbitofrontal cortex in motivational control of goal-directed behavior

Several findings from both human neuroimaging and nonhuman primate studies suggest that the posterior medial orbitofrontal cortex (OFC) may be critical for the motivational control of goal-directed behavior. The present study was conducted to clarify the role of the left and right posterior medial OFC in that function by examining the effects of focal unilateral lesions to this region on the performance on an incentive working memory task. The study covered patients who had undergone surgery for an ACoA aneurysm and normal control subjects (C). The patients were subdivided into three groups: those with resection of the left (LGR+) or right (RGR+) posterior part of the gyrus rectus, and without such a resection (GR−). Participants performed a 2-back working memory task under three motivational conditions (penalty, reward, and no-incentive). The C group performed worse in the penalty condition and better in the reward condition as compared to the no-incentive condition. Similar results were obtained for the GR− group. Performance of the LGR+ group did not depend on incentive manipulations, whereas the RGR+ group performed better in both the penalty and reward conditions than in the no-incentive condition. The results show that the posterior medial OFC is involved in the motivational modulation of working memory performance. Our findings also suggest that the left posterior medial OFC plays a crucial role in this function, whereas the right posterior medial OFC is particularly involved in the processing of the punishing aspect of salient events and it probably mediates in guiding behavior on the basis of negative outcomes of action.     

Psychological aspects of the transformations in poland: Changes in the sense of participation in the life of a plant

Abstract

In order to promote innovation, most theorists agree, high levels of participation by all employees in an organization is required. In Eastern Europe nation-wide interventions are underway in some countries to promote participation across all organizations. This article describes one study of this phenomenon.
