Neurophysiological evidence for categorical perception of color

The aim of this investigation was to examine the time course and the relative contributions of perceptual and post-perceptual processes to categorical perception (CP) of color. A visual oddball task was used with standard and deviant stimuli from same (within-category) or different (between-category) categories, with chromatic separations for within- and between-category stimuli equated in Munsell Hue. CP was found on a behavioral version of the task, with faster RTs and greater accuracy for between- compared to within-category stimuli. On a neurophysiological version of the task, event-related potentials (ERPs) showed earlier latencies for P1 and N1 components at posterior locations to between- relative to within-category deviants, providing novel evidence for early perceptual processes on color CP. Enhanced P2 and P3 waves were also found for between- compared to within-category stimuli, indicating a role for later post-perceptual processes.     

Women's human rights violations: Cameroonian students' perceptions

Cameroonian university students (N = 666) assessed whether certain different societal positions that the law grants to women and men (the husband chooses the marital home, the husband wields parental power, a married woman cannot freely engage in trade, the husband administers his wife's personal property) and certain cultural practices (female genital mutilation, parents arranging their children's marriage) were seen as violations of women's human rights. Justifications for the choices were also analysed. Female genital mutilation was most often seen as a violation of women's human rights, and the husband selecting the marital home was least often seen as a violation. These differences were explained by cultural specificities. Women more often than men saw the cases as violations of rights. Respondents coming from the North saw the cases less often as violations of rights than respondents from other geocultural areas, which was in accordance with their previously observed higher collectivism.

The shift in infant preferences for vowel duration and pitch contour between 6 and 10 months of age

This study investigates the influence of the acoustic properties of vowels on 6‐ and 10‐month‐old infants’ speech preferences. The shape of the contour (bell or monotonic) and the duration (normal or stretched) of vowels were manipulated in words containing the vowels /i/ and /u/, and presented to infants using a two‐choice preference procedure. Experiment 1 examined contour shape: infants heard either normal‐duration bell‐shaped and monotonic contours, or the same two contours with stretched duration. The results show that 6‐month‐olds preferred bell to monotonic contours, whereas 10‐month‐olds preferred monotonic to bell contours. In Experiment 2, infants heard either normal‐duration and stretched bell contours, or normal‐duration and stretched monotonic contours. As in Experiment 1, infants showed age‐specific preferences, with 6‐month‐olds preferring stretched vowels, and 10‐month‐olds preferring normal‐duration vowels. Infants’ attention to the acoustic qualities of vowels, and to speech in general, undergoes a dramatic transformation in the final months of the first year, a transformation that aligns with the emergence of other developmental milestones in speech perception.     

Are novice drivers overconfident? A comparison of self-assessed and examiner-assessed driver competences in a Finnish and Swedish sample

Studies of subjective driving skill have usually assessed perceived driving skill in relation to the skills of the average driver. In order to examine whether novice drivers are overconfident with respect to their actual skills, a different method was used in the present study, where specific aspects of perceived driver competence were compared with assessments made by a driver examiner. A Finnish (n = 2847) and a Swedish (n = 805) sample of driving test candidates completed self-assessments and took a practical driving test; the instruments differed between the countries. The results indicated that about 50 percent of the Finnish and between 25 and 35 percent of the Swedish candidates made realistic assessments of their competence in the areas Vehicle manoeuvring, Economical driving and Traffic safety. The proportion of those who overestimated their competence was greater among the Swedish candidates than the Finnish candidates. This might be explained by greater possibilities of practicing self-assessment in the Finnish driver education. Furthermore, the results indicate that males are not overconfident to a greater extent than females. In conclusion, when perceived competence is related to actual competence instead of the skills of the average driver, the majority of drivers are no longer found to overestimate their skills.     

‘Peace in a Thatched Hut—that is Happiness’: Subjective Wellbeing Among Peasants in Rural China

Existing research about subjective wellbeing (SWB) in China is confined to student and urban samples, even though 60% of the population reside in rural areas. It is reasonable to predict that there could be a rural-urban difference in SWB as there is a marked difference in objective (socio-economic) measures of wellbeing. The present study measured SWB within a sample of Chinese peasants living in a remote farming village. The results show that despite their relatively low socioeconomic conditions, the rural residents’ satisfaction levels were within the normative range for the Chinese population, and generally did not differ significantly from a previously published study in an affluent Chinese region (Hong Kong). In-depth interviews with participants revealed that the lower living conditions in the rural area are not adverse to drive SWB below the normative range.

Regulatory fit as a determinant of sport performance: How to succeed in a soccer penalty-shooting

ObjectivesAccording to regulatory focus theory, goal pursuit can be achieved by either keeping a promotion or a prevention focus [Higgins, E. T. (1997). Beyond pleasure and pain. American Psychologist, 52, 1280–1300; Higgins, E. T. (2000). Making a good decision: value from fit. American Psychologist, 55, 1217–1230]. Moreover, it has been assumed that people experience fit when they pursue a goal in a manner that sustains their chronic orientation and that fit has a positive impact on performance. In two studies, we investigated the significance of regulatory focus and fit in the realm of sports performance, such as the success rate in a soccer penalty-shooting task.Methods and ResultsIn a pilot study, we assessed the chronic regulatory orientation of 211 athletes from different sports. Among others, we found more promotion focus with attackers than with defenders. In the main study, we assessed the chronic regulatory orientation of 20 soccer players who took part in a penalty-shooting task. For half of them, the task was described in terms of promotion, for the others in terms of prevention. We found a positive impact of regulatory fit on scoring performance.ConclusionsOur findings demonstrate a great potential of regulatory focus theory for the understanding and enhancement of sport performance. The assessment of athletes' chronic regulatory orientation could be of importance for the selection of athletes, the adjustment of tactics and strategies, and coaches' framing of instructions.     

Films for eliciting emotional states in children

Standardized sets of films have been shown to be effective for eliciting emotional states in adults, but no comparable validated stimuli are available for children. We therefore examined the effects of three pre-selected film clips each of 3-min duration in eliciting a pleasant, neutral and unpleasant emotional state in 297 children aged between 6 and 12 years. After the films were presented on a video projector, affective ratings were obtained with the Self-Assessment-Manikin on the emotional dimensions of valence and arousal. Increasing pleasure ratings were observed from the unpleasant to the neutral to the pleasant film. Associated arousal ratings were stronger for the unpleasant and pleasant films compared to the neutral film. Overall, results showed successful elicitation of targeted emotional states only marginally influenced by age, gender or prior experience with the films. The use of these films is therefore suggested for future studies on emotions in children.     

Forensic psychology in the Czech republic

The article discusses the field of Forensic Psychology in Czech Republic. It concentrates upon the successes and stagnations of the field, which can be attributed to the political and historical development of the country. After a brief historical background and demographic information, the article introduces the history and structure of the police force and prison service. The article then moves on to discuss the history and publication development of the field of Forensic Psychology and its use in practice. It characterizes the field from its beginnings between the two wars, to the activities of the Research Institute of Penology from 1967 to1980 and the years following the political change of 1989. The article concludes with the law framework within which the field operates. Based upon this summary of the situation in Czech republic, the author makes an assessment of the status of Forensic Psychology in Czech republic, especially in terms of conducting research for the practice.

Maintaining an open mind to closed individuals: The effect of resource availability and leadership style on the association between openness to experience and organizational commitment

This paper examines whether workplace characteristics, particularly resource availability and transformational leadership, moderate the association between openness to experience and organizational commitment. In Study 1, 205 employees completed a questionnaire that assessed their openness, organizational commitment, and perceived availability of resources at their organization. Openness reduced the extent to which individuals felt obliged to remain loyal to the organization, although this association diminished as resources became more accessible. In Study 2, 312 employees completed a similar questionnaire that also gauged the perceived leadership style of their supervisors. Transformational leadership amplified the positive relationship between openness and organizational commitment. These findings align with the proposition that individuals are more committed in work environments that facilitate the expression of their traits.     

Patterns of Natural Language Use: Disclosure, Personality, and Social Integration

When people write about their deepest thoughts and feelings about an emotionally significant event, numerous benefits in many domains (e.g., health, achievement, and well-being) result. As one step in understanding how writing achieves these effects, we have developed a computer program that provides a "fingerprint" of the words people use in writing or in natural settings. Analyses of text samples indicate that particular patterns of word use predict health and also reflect personality styles. We have also discovered that language use in the laboratory writing paradigm is associated with changes in social interactions and language use in the real world. The implications for using computer-based text analysis programs in the development of psychological theory are discussed.
