Sensorimotor synchronization: Motor responses to regular auditory patterns

Subjects (N = 32) were asked to synchronize a motor response with tones in auditory patterns. These patterns were created from six tones and six intertone intervals of equal duration. The pitch of the first tone differed from the others. It was found that subjects used three types of timing in their motor response: (1) the first intertone interval was prolonged and the second interval was shortened, (2) the second intertone interval was prolonged and the first interval was shortened, and/or (3) the first interval and the second interval were of approximately the same length. The prolongation of the fifth interval was observed during all three types of timing. The results are explained using the concept of suprasegmental control of timing, which explains a prolongation of intervals at critical control point of the patterns. The occurrence of three different strategies of timing is discussed in connection with similar principles in musical performance.

“Doing Good” versus “Being Good”: The interplay between pride appeals and regulatory-focused messages in green advertising

Many consumers feel proud of making green choices, which is of crucial relevance to explaining environmentally responsible behaviors. However, compared to other self-conscious emotions, such as guilt and shame, little research attention has been paid to the role of pride in green consumerism. Through conducting two online experimental surveys, this research examined what features of a message induce the two facets of the emotion pride—authentic and hubristic—and how pride appeals interact with message frames having different regulatory foci. In Study 1, participants revealed more favorable eco-friendly attitudes and intentions when hubristic pride appeals were combined with promotion-focused messages (detailing the positive benefits of using the green product), and when authentic pride appeals were matched with prevention-focused messages (emphasizing the negative consequences averted by using the green product). Study 2 replicated and supported the proposed matching hypotheses while including a control condition. Findings of this research will add to a growing body of literature on pride as a discrete emotion and its carryover effects on persuasion while providing guidelines to help practitioners design green advertising campaigns.     

Investigation of the psychometric properties of the Perceived Parental Autonomy Support Scale in the Southeastern European context

The Perceived Parental Autonomy Support Scale (P-PASS) is an instrument designed to measure parental autonomy-support and control of late adolescents and emerging adults. The present paper examines the process of adapting the P-PASS to the Romanian culture. Four studies were conducted, investigating: 1) the adequacy of the translation, using a multidimensional scaling of expert ratings; 2) construct validity, through exploratory approaches; 3) various psychometric properties, such as reliability and construct validity, through confirmatory approaches; convergent validity through comparisons with other measures of parental autonomy support (College-Student Scale of the Perceptions of Parents Scales) and control (Psychological Control Scale–Youth Self-Report), and predictive validity in relation with general self-efficacy; 4) test-retest reliability. The results show that the Romanian version of the P-PASS has sound psychometric properties. Confirmatory Factor Analysis indicates that a structure with two second order factors fits the data best and that the measure is equivalent with the original Canadian version. Also, it shows adequate test-retest reliability at 6 months and one year between administrations, good convergent validity, and a good prediction of general self-efficacy.

     

Refugee students' perspectives on inclusive and exclusive school experiences in Austria

This paper examines refugee students' experiences in the Austrian mainstream school system. It highlights four areas: school connectedness, social exclusion, support systems and friendships. In the study, 55 refugee students between 8 and 21 years old enrolled in primary and secondary education participated in a semi-structured interview. Data were analysed with directed qualitative content analysis, whereby codes were created deductively and inductively. Students stressed the importance of schooling in order to prosper in the future, particularly through language acquisition. Peers and bilingual teachers played an important role in their efforts to learn German and develop feelings of belonging in the school system. While language acquisition was important for the students, they indicated that other support measures (i.e., remedial education) were largely absent. Further, half of the students reported bullying experiences (verbal, social and physical) associated with their refugee status, language proficiency and religious affiliation. This study has implications for school professionals. The scope of support refugee students receive at school must be broadened, forced migration should be addressed in school in order to counteract negative effects of bullying students receive due to their refugee status and school connectedness can be promoted by hiring staff from diverse cultural backgrounds.     

Boys Just Don’t! Gender Stereotyping and Sanctioning of Counter-Stereotypical Behavior in Preschoolers

Sex Roles - Although children start to adopt gender stereotypes by the age of three, there is less evidence about how early they start to sanction other children’s counter-stereotypical...     

Metacognitions in proneness towards hallucinations and delusions

The objectives of the present study were to examine the degree of co-existence of hallucinations and delusions in the nonclinical population. In addition, we wished to investigate the role of metacognitions in hallucinations and delusions. Finally, we explored the relative roles of positive and negative metacognitive beliefs in proneness to hallucinations and delusions. Three hundred and thirty-one nonclinical participants completed instruments assessing: hallucination-proneness (Launay-Slade Hallucinations Scale; LSHS), delusion-proneness (21-item version of the Peters et al. Delusions Inventory; PDI-21) and metacognitive beliefs (Meta-Cognitions Questionnaire; MCQ). Participants were successively grouped according to their scores on the LSHS and the PDI-21. Results revealed that hallucination-proneness was positively and significantly associated with delusion-proneness. Furthermore, hallucination-prone and delusion-prone participants scored significantly higher on some sub-scales of the MCQ compared to non-prone participants. Finally, multiple regression analysis revealed that positive and negative beliefs were good predictors of proneness towards hallucinations and delusions.     

On quasivarieties and varieties as categories

Finitary quasivarieties are characterized categorically by the existence of colimits and of an abstractly finite, regularly projective regular generator G. Analogously, infinitary quasivarieties are characterized: one drops the assumption that G be abstractly finite. For (finitary) varieties the characterization is similar: the regular generator is assumed to be exactly projective, i.e., hom(G, –) is an exact functor. These results sharpen the classical characterization theorems of Lawvere, Isbell and other authors.Supported by the Czech Grant Agency (Project 201/02/0148).Special issue of Studia Logica: Algebraic Theory of Quasivarieties Presented by M.

Boundary distortions for neutral and emotional pictures

In two experiments, we examined Safer, Christianson, Autry, and Osterlund's (1998) claim that when emotional material is remembered, tunnel memory (i.e., the tendency to remember less of a scene than was actually shown) occurs. In Experiment 1, 81 undergraduate students drew photographs from memory after having briefly seen either four neutral or four emotional photographs. Both neutral and emotional drawings revealed boundary extension (i.e., the tendency to remember more of a scene than was actually shown). Experiment 2 relied on the camera distance paradigm (Intraub, Bender, & Mangels, 1992). In a recognition test, 60 undergraduate students judged the camera distance of previously seen neutral or emotional photographs. The majority of them demonstrated accurate judgments and neither extended nor restricted picture boundaries. Those participants who made an error more often displayed a boundary extension than a tunnel memory error. Taken together, our results suggest that boundary extension for neutral and emotional photographs is a more robust phenomenon than its counterpart, tunnel memory.
