Response–reinforcer dependency and resistance to change

The effects of the response–reinforcer dependency on resistance to change were studied in three experiments with rats. In Experiment 1, lever pressing produced reinforcers at similar rates after variable interreinforcer intervals in each component of a two‐component multiple schedule. Across conditions, in the fixed component, all reinforcers were response‐dependent; in the alternative component, the percentage of response‐dependent reinforcers was 100, 50 (i.e., 50% response‐dependent and 50% response‐independent) or 10% (i.e., 10% response‐dependent and 90% response‐independent). Resistance to extinction was greater in the alternative than in the fixed component when the dependency in the former was 10%, but was similar between components when this dependency was 100 or 50%. In Experiment 2, a three‐component multiple schedule was used. The dependency was 100% in one component and 10% in the other two. The 10% components differed on how reinforcers were programmed. In one component, as in Experiment 1, a reinforcer had to be collected before the scheduling of other response‐dependent or independent reinforcers. In the other component, response‐dependent and ‐independent reinforcers were programmed by superimposing a variable‐time schedule on an independent variable‐interval schedule. Regardless of the procedure used to program the dependency, resistance to extinction was greater in the 10% components than in the 100% component. These results were replicated in Experiment 3 in which, instead of extinction, VT schedules replaced the baseline schedules in each multiple‐schedule component during the test. We argue that the relative change in dependency from Baseline to Test, which is greater when baseline dependencies are high rather than low, could account for the differential resistance to change in the present experiments. The inconsistencies in results across the present and previous experiments suggest that the effects of dependency on resistance to change are not well understood. Additional systematic analyses are important to further understand the effects of the response–reinforcer relation on resistance to change and to the development of a more comprehensive theory of behavioral persistence.     

Perfectionism in Argentina and the United States: Measurement Structure,Invariance, and Implications for Depression

The Revised Almost Perfect Scale (APS–R; Slaney, Mobley, Trippi, Ashby, &; Johnson, 1996 Slaney, R. B., Mobley, M., Trippi, J., Ashby, J. S., &; Johnson, D. (1996). Almost Perfect Scale Revised. Psyctests. doi:10.1037/t02161-000[Crossref] , [Google Scholar]) was designed to measure perfectionistic strivings (standards), perfectionistic concerns (discrepancy), and preferences for neatness and organization (order). In this study, English and Spanish (Arana, Keegan, &; Rutsztein, 2009 Arana, F. G., Keegan, E. G., &; Rutsztein, G. (2009). Adaptación de una medida multidimensional de perfeccionismo: la Almost Perfect Scale–Revised (APS–R). Un estudio preliminar sobre sus propiedades psicométricas en una muestra de estudiantes universitarios argentinos [Adaptation of a measure of multidimensional perfectionism: The Almost Perfect Scale–Revised. A preliminary study about its psychometrical properties on a sample of Argentine university students]. Evaluar, 9, 35–53. [Google Scholar]) versions of the APS–R were compared in samples of 283 college students in Argentina and 311 U.S. students. The results offered support for cross-national scalar invariance for discrepancy and order items but standards items, with a few exceptions, raised concerns about their cross-national comparability. Tests of latent means revealed no differences between the countries for discrepancy, but the order factor mean was higher in the U.S. sample. Age and gender had negligible effects on measurement models. Discrepancy was strongly related to depressive symptoms for both samples. Unlike in the U.S. sample, there was a significant association for the Argentina sample between standards and discrepancy. Overall, results indicated that discrepancy items performed well, order items were adequate with some measurement adjustments, and standards items should be revisited for their cross-cultural utility. Translation issues and general values in Argentina and the United States (e.g., collectivism–individualism) are discussed that might affect how perfectionism is understood and measured in different cultural contexts.     

Sociopolitical Control for Immigrants: The Role of Receiving Local Contexts

This study examines the individual and contextual factors associated with sociopolitical control expressed by immigrants in southern Spain. We used hierarchical linear modeling to evaluate the relations between individual (community participation, social connectedness, and perceived cultural competence of receiving community services) and municipality characteristics (city community participation, city social connectedness, and city community services’ cultural competence) and immigrants’ feelings of sociopolitical control. Data were analyzed using a two‐level model based on 707 Moroccan immigrants in 25 municipalities. After adjusting for gender, educational level, and psychosocial confounding factors, we observed a positive association between social connectedness and sociopolitical control at the individual level. At the contextual level, we observed a positive association between (a) city community participation, (b) city social connectedness, and (c) city community services’ cultural competence, and sociopolitical control. Indeed, living in a municipality where there are community services with high levels of cultural competence and where, on average, many people participate in organizations and neighbors are connected, was associated with higher levels of perceived control in the sociopolitical domain for immigrants. We also discuss implications for community‐based research and practice.     

Access,phenomenology and sorites

The non‐transitivity of the relation looks the same as has been used to argue that the relation has the same phenomenal character as is non‐transitive—a result that jeopardizes certain theories of consciousness. In this paper, I argue against this conclusion while granting the premise by dissociating lookings and phenomenology; an idea that some might find counter‐intuitive. However, such an intuition is left unsupported once phenomenology and cognitive access are distinguished from each other; a distinction that is conceptually and empirically grounded.     

What predicts anti‐Roma prejudice? Qualitative and quantitative analysis of everyday sentiments about the Roma

The present research focused on two primary goals: (a) identifying the content of sentiments about the Roma to which Hungarians are exposed during everyday family conversations, and (b) determining which types of everyday sentiments about the Roma most strongly predict Hungarian respondents’ anti‐Roma prejudice. Content analyzing open‐ended responses from a representative sample of Hungarians (N = 505), we found that more than 76% of the respondents reported being exposed to negative stereotypes about the Roma, 27% to threats posed by Roma, and 16% to overt dehumanization of Roma; additionally more than 20% reported hearing no positive sentiments about the Roma in everyday family conversations. We then examined which negative and positive sentiments most strongly predicted respondents’ anti‐Roma prejudice (using measures of social distance and modern racism). Higher social distance scores were predicted by a lack of positive sentiments, whereas lower social distance scores were most strongly predicted by unambiguously positive sentiments expressed during family conversations. Higher modern racism scores were further predicted by sentiments expressing dehumanization, threat, and violence against Roma. Together, these results attest to the extremity of anti‐Roma sentiments expressed regularly by Hungarians, and suggest how exposure to specific sentiments may foster anti‐Roma hostility. Moreover, these findings provide guidance regarding the specific negative anti‐Roma sentiments that should be combated to enhance the effectiveness of anti‐prejudice interventions.     

Equivalences Among Polarity Algorithms

The concept of polarity is pervasive in natural language. It relates syntax, semantics and pragmatics narrowly (Giannakidou, in: Maienborn, von Heusinger, Portner (eds.), Semantics: an international handbook of natural language meaning, De Gruyter Mouton, Berlin, 2011; Israel in The grammar of polarity: pragmatics, sensitivity, and the logic of scales, Cambridge studies in linguistics, Cambridge University Press, Cambridge, 2014), it refers to items of many syntactic categories such as nouns, verbs and adverbs. Neutral polarity items appear in affirmative and negative sentences, negative polarity items cannot appear in affirmative sentences, and positive polarity items cannot appear in negative sentences. A way of reasoning in Natural Language is through Natural Logic (van Benthem in Essays in logical semantics, vol. 29 of Studies in linguistics and philosophy, Reidel, Dordrecht, 1986; Language in action: categories, lambdas, and dynamic logic, vol. 130 of Studies in logic, Elsevier, Amsterdam, 1991). This logic is based on the concept of polarity in order to make the meaning of a sentence weaker o stronger without changing its truth value. There exist many proposals to compute polarity in the Natural Logic context, the most widely known are the ones by: van Benthem (1986, 1991), Sánchez-Valencia (Studies on natural logic and categorial grammar, Ph.D. thesis, Universiteit van Amsterdam, 1991), Dowty (Proceedings of the 4th conference on semantics and theoretical linguistics, Cornel University, CLC Publications, Rochester, 1994), and van Eijck (in: ten Cate, Zeevat (eds.), 6th international Tbilisi symposium on logic, language, and computation, Batumi, Georgia, Springer, 2007). If Natural Logic is going to be used, as an inferential mechanism between text fragments, in Natural Language Processing applications such as text summarization, question answering, and information extraction, it is a priority to know what the existing relationship among the aforementioned algorithms is; for example, to implement the most general. We show in this paper the equivalence among the analyzed algorithms, filling a gap in Natural Logic research, particularly in computing polarity, and the soundness of their algorithms.     

Counselors’ Mandated Responsibility to Report Child Maltreatment: A Review of U.S. Laws

Although counselors in 44 states are mandatory reporters of child maltreatment, they may lack an understanding of their legally designated role. This article presents the results of a systematic review of child maltreatment reporting laws in all 50 states and the District of Columbia. The authors apply relevant legislation to real‐life contexts for counselors.     

Acute Aerobic Exercise Enhances Students’ Creativity

The purpose of this study was to evaluate the effectiveness of an aerobics games class on creativity in children during the school day. Participants were 96 students (age = 9.84 ± 1.12 years), 48 girls and 48 boys. The students were randomly assigned to the experimental group (EG, n = 48) or the control group (CG, n = 48). The Prueba de Imaginación Creativa-Niños (PIC-N) test was employed to assess narrative and graphic creativity. The EG took part in an aerobic games session lasting 45 min; the CG did not take part in a physical education class on that school day. As for group × time interaction, the EG experienced significant improvements in all creativity variables except in graphic originality, graphic titles, and graphic details. The CG did not improve any creativity variables. The findings suggest that acute aerobic exercise can enhance students’ creativity, which could be important for academic achievement.     

A current approach to anticipation in sport / Un enfoque actual de la anticipación en el deporte

The classical cognitive concept of anticipation and timing (for example, reaction time) somewhat limits the study of sports actions under spatio-temporal pressure. The presence, duration and evolution of the information of the opponents, spatio-temporal pressure, the evolution of the athlete’s response movements or the degree of representativeness are some of the issues facilitating research into an anticipation that is better adjusted to the specific circumstances of interception tasks. This article proposes that temporalization of response actions is based on the balance between the spatio-temporal demands of the task, the athlete’s action capabilities and the evolution of the reliability of the available variables. In order to obtain good performance in these actions under pressure, individual perceptual differences and possible interactions with other information sources must also be considered.     

Optimism as a mediator between resilience and affective states in older adults / El optimismo como mediador entre la resiliencia y estados afectivos en adultos mayores

Abstract

The purpose of this study was to explore whether resilience is associated with and a predictor of depression, anxiety, negative and positive affect, life satisfaction and subjective happiness in older adults, and whether these relationships are mediated by optimism. To analyse this, different scales were administered to a sample of 240 elderly people and correlational and mediational analysis was carried out. The results showed relationships between all the variables. Similarly, we found that optimism is a partial mediator of the relationship between resilience and the aforementioned variables. Our results evidenced that increasing resilience and optimism in elderly people could be favourable to successful ageing.
