Perceptual Variation,Color Language,and Reference Fixing. An Objectivist Account

I offer a new objectivist theory of the contents of color language and color experience, intended especially as an account of what normal intersubjective variation in color perception and classification shows about those contents. First I explain an abstract account of the contents of (utterances of) color and other gradable adjectives; on the account, these contents are certain objective properties constituted in part by contextually intended standards of application, which are in turn values in the dimensions of variation associated with the adjectives. Then I propose an explanation of normal variations in linguistic color classification; these are postulated to be effects of differences in intended standards for the color adjectives appearing in the classifying predicates. Next, I consider a potential objection to this explanation, based on the suggestion that contextual content should be more accessible than the explanation predicts. In reply, I point out that contextual content is occasionally opaque to unsophisticated reflection. Finally, I present a companion account of the contents of color experiences on which these represent an object as lying on certain salient intervals in the chromatic dimensions, and I show how the account accommodates intersubjective variation in color perception.     

Recruiting and Assessing Recent Young Adult Latina Immigrants in Health Disparities Research

The authors interviewed 4 researchers to identify facilitators in recruiting and assessing Latina immigrants. The 4 researchers recruited 530 recent Latina immigrants (ages 18–23 years) for a study of social and cultural determinants of health. Consensual qualitative research methods revealed that respondent‐driven sampling was an effective recruitment method. Fear of deportation was a barrier. Stigma about sensitive topics (e.g., sex, drug use) did not affect participation. Findings can help counselors conduct health disparities research. Los autores entrevistaron a 4 investigadores para identificar facilitadores para el reclutamiento y evaluación de inmigrantes latinas. Los 4 investigadores reclutaron a 530 mujeres latinas que habían inmigrado recientemente (edades entre 18 y 23 años) para un estudio de los factores sociales y culturales determinantes de la salud. Los métodos de investigación cuantitativa consensuados revelaron que el muestreo dirigido por las encuestadas fue un método efectivo de reclutamiento. El miedo a la deportación fue un obstáculo. El estigma asociado a temas delicados (p. ej., el sexo, el uso de drogas) no afectó a la participación. Los hallazgos pueden ayudar a los consejeros a realizar estudios sobre disparidades en la salud.     

Avoidance learning by Guinea pigs

Albino guinea pigs were trained in shuttle-boxes. Superior performances were achieved with longer CS-US (15 sec. against 5 sec.) and intertrial intervals (90 sec. against 30 sec.). There were no performance increments within sessions, but improvements in performance occurred between sessions. Consolidation mechanisms probably play an important part in avoidance learning by guinea pigs.     

Adult Attachment Style and Cognitive Reactions to Positive Affect: A Test of Mental Categorization and Creative Problem Solving

Three studies examined the moderating effect of attachment style on cognitive reactions to positive affect inductions. In Study 1 (N = 110), participants completed attachment style scales, were asked to retrieve a happy or a neutral memory, and, then, performed a categorization task. Study 2 (N = 120) used the same affect induction, while examining creative problem solving in the Remote Associates Test. Study 3 (N = 120) replicated Study 2, while using another affect induction (watching a comedy film) and controlling for trait anxiety scores. Overall, securely attached persons reacted to positive affect with broader categorization and better performance in creative problem-solving tasks. Anxious–ambivalent persons showed an opposite pattern of cognitive reactions to positive affect, and avoidant persons showed no difference in their cognitive reactions to positive and neutral affect inductions. The discussion emphasizes the role that attachment-related strategies of affect regulation may play in episodes of positive affect.     

A Note on Formality and Logical Consequence

Logic is formal in the sense that all arguments of the same form as logically valid arguments are also logically valid and hence truth-preserving. However, it is not known whether all arguments that are valid in the usual model-theoretic sense are truth-preserving. Tarski claimed that it could be proved that all arguments that are valid (in the sense of validity he contemplated in his 1936 paper on logical consequence) are truth-preserving. But he did not offer the proof. The question arises whether the usual model-theoretic sense of validity and Tarski's 1936 sense are the same. I argue in this paper that they probably are not, and that the proof Tarski had in mind, although unusable to prove that model-theoretically valid arguments are truth-preserving, can be used to prove that arguments valid in Tarski's 1936 sense are truth-preserving.     

Why and when justice sensitivity leads to pro- and antisocial behavior

People differ in how injustice-sensitive they are either as victims or as observers. Whereas observer sensitivity is positively related to cooperative behavior, victim sensitivity promotes antisocial and egoistic behavior. The present article investigates the dynamics underlying these effects. Participants played an online-based public goods game and were informed about the number of people who violated a fairness rule in previous rounds of the game (no, some, or many violators). High victim-sensitive participants contributed less to the public good even in the “some violators” condition. High observer-sensitive participants contributed more to the public good even in the “many violators” condition. The findings correspond with the sensitivity to mean intentions model and cannot be explained by individual differences in general trust.     

Competition between two memory traces for long-term recognition memory

Previous studies investigating the processes which underlie memory consolidation focused almost exclusively on isolated learning events. Here I studied the competition of two similar memory traces for consolidation non-conditioned recognition memory in adult male C57BL/6JOlaHsd mice using the olfactory cues based social discrimination procedure. My results show that the interference phenomena that cause forgetting are time-dependent, and that retroactive interference can be discriminated from proactive interference. Furthermore, both types of interference can be suppressed by subcutaneous anisomycin treatment immediately after presentation of the interference stimulus. These findings imply that interference phenomena, which result from the competition of two similar memory traces for long-term recognition memory, are related to the progress of memory consolidation and linked to protein synthesis.     

The challenge of measuring immigrant origin and immigration-related ethnicity in Europe

Different European nation-states use the most diverse statistical constructions of foreign origin or ethnic minority populations. Several countries traditionally even shun from producing such data. This makes international comparison a very difficult endeavour. Anyone wanting to perform comparative research on immigrants or (immigrant origin) ethnic minorities in Europe is unavoidably confronted with the most diverse types of national statistical data and has to opt for ad hoc solutions. Attempts at international comparison can thus be very tricky due to data characteristics. It is important that researchers are aware of these problems and do not simply accept data (especially in comparisons) at face value. In this article we embark on a comparative explorative study of the way in which immigrant background and immigration related ethnicity is taken stock of by national statistical institutes in a set of European nation-states.
