Predator videos and electric shock function as punishers for zebrafish (Danio rerio)

Zebrafish (Danio rerio) are a promising animal model for studying the effects of gene–environment interactions on behavior. Two experiments were conducted to assess punishment effects of presenting predator videos (Indian leaf fish; Nandus nandus) and electric shock on operant approach responses in zebrafish. In Experiment 1, the predator video and shock stimuli were presented upon a response maintained by a single variable‐interval schedule of food reinforcement in different groups of fish. In Experiment 2, the predator video and shock stimuli were presented upon one of two response alternatives maintain by concurrently available variable‐interval schedules of food reinforcement in different groups of fish. Responding decreased when the predator video and shock stimuli were presented relative to their absence in both experiments. Moreover, responding on an unpunished alternative did not reliably decrease in Experiment 2. These results indicate that the decrease in responding resulted from the punishment contingency rather than from elicited species‐specific defense responses or conditioned avoidance. Thus, the predator video and electric shock functioned as punishers of operant behavior for zebrafish. Identifying punishers for this species could lead to research on how gene–environment interactions influence individual differences in sensitivity to punishment.     

Modelling argumentation and modelling with argumentation

This paper discusses the epistemological and methodological bases of a scientific theory of meaning and proposes a detailed version of a formal theory of argumentation based on Anscombre and Ducrot's conception. Argumentation is shown to be a concept which is not exclusively pragmatic, as it is usually believed, but has an important semantic body. The bridge between the semantic and pragmatic aspects of argumentation consists in a set of gradual inference rules, called topoi, on which the argumentative movement is based. The content of each topos is determined at the pragmatic level, while the constraints on the forms of the topoi attached to a sentence are determined at the semantic level. Applications and possible applications toartificial intelligence and to cognitive sciences are discussed. In particular, the gradual models used to account for argumentation are shown to be extremely promising for Knowledge management, a discipline which includes knowledge acquisition, knowledge representation, transmission of knowledge (communication, interfaces, etc.), knowledge production (decision help, reasoning, etc.). A first formal model is presented and discussed: it is shown in details how it accounts for most of the argumentative features of sentences containing but, little and a little, and how it can be extended to describe sentences containing other argumentative connectives. However, this model is shown to be too simple and to violate the compositionality principle, which is shown, in the first section, to bean important methodological principle for any scientific theory. After a detailed analysis of the possible reasons for this violation, an improved model is proposed and its adequacy is discussed.     

Response acquisition by zebrafish (Danio rerio) with delayed reinforcement

Zebrafish (Danio rerio) is a common vertebrate animal model in biomedical research and is a promising species for studying how genes interact with environmental factors in determining behavior. The present study investigated how reinforcement parameters affect zebrafish behavior by assessing response acquisition with delayed reinforcement, which has been studied with other species (e.g., rats, pigeons, humans, etc.) but not with zebrafish. Twenty‐four experimentally naïve subjects were exposed to a tandem fixed‐ratio 1 differential‐reinforcement‐of‐other‐behavior x‐s schedule of reinforcement, where x varied across subjects. There were six different delay‐to‐reinforcement durations and sets of four fish were assigned to each delay duration. All of the fish assigned to a 0‐, 0.5‐, or 1‐s delay acquired responding. Two fish acquired responding with a 3‐s delay and one fish appeared to have acquired it with a 6‐s delay although the latter result was less clear. None acquired responding with a 12‐s delay. These results suggest that zebrafish behavior is sensitive to delays to reinforcement and the time frame over which reinforcement is effective may be limited approximately to 6 s. This time frame is shorter than that found with other species. Practical and theoretical implications of the present finding are discussed.     

“Yesterday Redeemed and Tomorrow Made More Beautiful”: Historical Injustice and Possible Collective Selves

This research examines the ways in which talk about reparations for historical injustice demonstrates individuals' ambitions for future collective identities. Interviews with White Tulsans (n = 25) illustrate how discursive temporal constructions justify support for or opposition to reparations for the 1921 Tulsa Race Riot. It is argued that White Tulsans strategically employed these constructions to either transform or maintain collective identities. These findings bring a discursive approach to theories of collective continuity (Sani, Bowe, & Herrera, 2008) and possible selves (Cinnirella, 1998; Markus & Nurius, 1986; McAdams, 2006; Vignoles, 2008). From this perspective, reckoning with the past is as much about who we can be tomorrow as it is guilt for who we were yesterday.     

Trust in Nanotechnology? On Trust as Analytical Tool in Social Research on Emerging Technologies

Trust has become an important aspect of evaluating the relationship between lay public and technology implementation. Experiences have shown that a focus on trust provides a richer understanding of reasons for backlashes of technology in society than a mere focus of public understanding of risks and science communication. Therefore, trust is also widely used as a key concept for understanding and predicting trust or distrust in emerging technologies. But whereas trust broadens the scope for understanding established technologies with well-defined questions and controversies, it easily fails to do so with emerging technologies, where there are no shared questions, a lack of public familiarity with the technology in question, and a restricted understanding amongst social researchers as to where distrust is likely to arise and how and under which form the technology will actually be implemented. Rather contrary, ‘trust’ might sometimes even direct social research into fixed structures that makes it even more difficult for social research to provide socially robust knowledge. This article therefore suggests that if trust is to maintain its important role in evaluating emerging technologies, the approach has to be widened and initially focus not on people’s motivations for trust, but rather the object of trust it self, as to predicting how and where distrust might appear, how the object is established as an object of trust, and how it is established in relation with the public.     

Power equivalence in structural equation modelling

Implementing large‐scale empirical studies can be very expensive. Therefore, it is useful to optimize study designs without losing statistical power. In this paper, we show how study designs can be improved without changing statistical power by defining power equivalence, a relation between structural equation models (SEMs) that holds true if two SEMs have the same power on a likelihood ratio test to detect a given effect. We show systematic operations of SEMs that maintain power, and give an algorithm that efficiently reduces SEMs to power‐equivalent models with a minimal number of observed parameters. In this way, optimal study designs can be found without reducing statistical power. Furthermore, the algorithm can be used to drastically increase the speed of power computations when using Monte Carlo simulations or approximation methods.     

The role of factor analysis in the development and evaluation of personality scales

The purpose of this paper is to examine the usefulness of factor analysis in developing and evaluating personality scales that measure limited domain constructs The approach advocated follows from several assumptions that a single scale ought to measure a single construct, that factor analysis ought to be applied routinely to new personality scales, and that the factors of a scale are important if it can be demonstrated that they are differentially related to other measures A detailed study of the Self-Monitoring Scale illustrates how factor analysis can help us to understand what a scale measures A second example uses the self-esteem literature to illustrate how factor analysis can clarify the proliferation of scales within a single content domain Both examples show how factor analysis can be used to identify important conceptual distinctions Confirmatory techniques are also introduced as a means for testing specific hypotheses It is concluded that factor analysis can make an important contribution to programmatic research in personality psychology     

Incorporating Idiographic Approaches Into Multicultural Counseling Research and Practice

Much of multicultural research has been based on normative methodological approaches. In this article, the authors discuss how idiographic approaches can be used to further explore issues that are relevant to multicultural counseling. Case examples are presented to illustrate how this approach can be used to improve understanding regarding the development of racial identity. Muchas de las investigaciónes multiculturales se ha basado en enfoques metodológicos normativos. En este artículo, los autores discuten cómo enfoques de ideograma pueden ser utilizados a explorar aún más los asuntos que son aconsejar multicultural pertinente. Los ejemplos del caso se presentan para ilustrar cómo este enfoque se puede utilizar para entender mejor la identidad racial.     

What is The Red Book for analytical psychology?

Abstract: The Red Book enters the field of analytical psychology belatedly, yet presents itself as a foundational text. In this paper, I try to estimate how it will affect the field and to reflect on how it can be used by contemporary readers and clinicians. Jung's own works remain the baseline for theorizing and teaching the fundamental perspectives of analytical psychology, and yet the field has grown far beyond his own contributions. Is this late inheritance of central value or only of peripheral interest for the field? It can be used in various ways and certainly shows many interesting features that link it to Jung's later works, but does it detract or does it add? And if it adds, what does it add? In The Red Book, Jung is speaking to us from the grave. What is he saying? In this paper, I explore how it can be used as an inspirational text for keeping alive the spirit of the ancestors in the field and for linking the present to the deep past.     

To boldly go where no relationship has gone before: Commentary on interpersonal relationships in the digital age

Individuals have a need to maintain positive social interactions, and with the advent of new-media technologies, there are a myriad ways individuals can satisfy this need by engaging socially in mediated (non-face-to-face) communication, hence the need for a special issue on “Relationships in the Digital Age.” The articles in this special issue reflect the need to answer theoretical questions brought forth by the increased tendency for individuals to create and maintain interpersonal relationships through mediated forms of communication. The commentary highlights the need for increased research on mediated interpersonal relationships by psychologists and discusses how the articles in the issue can be used to answer theoretical questions about mediated interpersonal communication. The article ends with speculation on how media may create social spaces that may be advantageous for some individuals.     

Using Noldus Observer XT for research on deaf signers learning to read: An innovative methodology

Despite years of research on the reading problems of deaf students, we still do not know how deaf signers who read well actually crack the code of print. How connections are made between sign language and written language is still an open question. In this article, we show how the Noldus Observer XT software can be used to conduct an in-depth analysis of the online behavior of deaf readers. First, we examine factors that may have an impact on reading behavior. Then, we describe how we videotaped teachers with their deaf student signers of langue des signes québécoise during a reading task, how we conducted a recall activity to better understand the students’ reading behavior, and how we used this innovative software to analyze the taped footage. Finally, we discuss the contribution this type of research can have on the future reading behavior of deaf students.     

Booming clangs and whispering ghosts: Attending to the reflexive echoes in IPA research

ABSTRACT

In this article, we propose reflexivity can be revealed through a deliberate adjunct to the interpretative phenomenological analysis (IPA) process. This adjunct, which we refer to as “echoes,” is a mixture of the participant’s and researcher’s words and experiences resonating with each other during the research process. We argue that explicitly recognising echoes gives a heightened sensitivity to both the researcher’s own place and being in the research, and to the other in relation to the researcher. Exploring the echoes enables the researcher to work with, rather than dismiss, his or her own presuppositions and exposes greater phenomenological sensibility toward the research subject and is-ness of that phenomenon. The purpose of this article is to outline how attending to echoes is a strategy for IPA researchers to promote and overtly journal reflexivity as central within their research practices. To exemplify how echoes can be used, practical examples from a doctoral research project are given to demonstrate how resonance can explicate reflexivity in the IPA process.     

A one-trial inhibitory avoidance task to zebrafish: Rapid acquisition of an NMDA-dependent long-term memory

The behavioral tasks aiming to evaluate learning and memory mechanisms currently available to zebrafish (Danio rerio) involve long training sessions frequently along multiple days and are based on shuttle box or active-avoidance protocols, preventing a detailed analysis of cellular and molecular time-dependent processes involved in memory acquisition and consolidation. In order to explore zebrafish’s potential contribution to the characterization of the molecular machinery underlying learning and memory rapidly acquired and reliable paradigms are necessary. In this study we present a rapid and effective learning protocol in a single-trial inhibitory avoidance in zebrafish. In a simple apparatus, adult animals learned to refrain from swimming from a white into a dark compartment in order to avoid an electric shock during a single-trial training session that lasted less than 2 min. The resulting memory is robust, long-lasting and sensitive to NMDA-receptor antagonist MK-801 given in the tank water immediately after training. Experiments aiming to further characterize the events underlying memory formation, retrieval or extinction or those looking for cognitive profiling of mutants, neurotoxicological studies and disease models may benefit from this task, and together with complementary strategies available for zebrafish may significantly improve our current knowledge on learning and memory mechanisms.     

Licking and liking: The assessment of hedonic responses in rodents

Affective processes are a key determinant of behaviour: At its simplest, liked stimuli are approached while disliked stimuli are avoided. Although assessing hedonic responses in nonverbal animals can be difficult, one relatively tractable approach relies on detailed analyses of rodents' consummatory behaviour. Rodents typically produce rhythmic sets of licks that can be grouped into clusters on the basis of the intervals between licks. The mean number of licks in a cluster (cluster size) is directly related to the concentration of palatable and unpalatable solutions. These relationships suggest that lick cluster size might be a useful index of an animal's hedonic reaction to the solution being consumed. I begin by reviewing studies of conditioned flavour preference and aversion that support the idea that lick cluster size can provide useful information about rats' hedonic reactions. I then describe how this methodology has been used to address previously intractable issues in the investigation of contrast effects as well as revealing an analogue of effort justification effects that, in humans, are commonly explained in terms of cognitive dissonance reduction. Finally, I consider how lick analysis might provide information about hedonic responses in animal models of human psychiatric disorders. In all these cases, how an animal did something was particularly informative about why it was doing it.

     

Guidance on conducting and reviewing systematic reviews (and meta-analyses) in work and organizational psychology

Systematic reviews and meta-analyses are means of summarizing and synthesizing research evidence in a given topic area. They can be used to define the current state of knowledge and how confident we can be in that knowledge, to identify evidence gaps, and to provide recommendations for policy and practice based on the best available evidence. At European Journal of Work and Organizational Psychology, our editorial stance is explicitly to encourage the conduct of systematic reviews and meta-analyses. The purpose of this editorial is to provide some guidance to authors and journal referees on the (technical) features of good systematic reviews.     

Applying Theories of Communal Motivation to Sexuality

One important but challenging aspect of maintaining a satisfying romantic relationship is keeping the sexual spark alive. Research suggests the importance of a couple's sexual connection in the maintenance of their relationship, but sustaining high levels of desire for a partner over the course of time can be difficult. In the current review, we argue that one novel approach to understanding how couples might maintain desire and satisfaction over the course of time in their relationships is applying theories of communal motivation to the domain of sexuality. In this line of research, we have demonstrated that people high in sexual communal strength – those who are motivated to be non‐contingently responsive to their partners' sexual needs – are able to sustain higher sexual desire over the course of time and navigate sexual disagreements in a way that maintains both partners' relationship quality. Future research directions include broadening the view of sexual needs to include the need to decline or reject a partner's sexual advances and investigating how partners manage unmet sexual needs.     

Methods of materiality: participant observation and qualitative research in psychology

This article challenges the hegemonic status of “language” as the primary substance of qualitative research in psychology, whether through interviews or recordings of naturally occurring talk. It thereby questions the overt focus on analyzing linguistic “meaning.” Instead, it is suggested that researchers should start paying attention to the material world (consisting of both human bodies and material objects) and what it means for how people live their lives. It is argued that this can be done by incorporating the concept of material presence to capture embodied and material layers of existence, and the method of participant observation is suggested as a viable approach to achieve this end. An empirical example of how authority is produced in a parent-teacher conference, not only through language but also through material objects and embodied being, is then presented. The article concludes by suggesting practical guidelines for incorporating attention to materiality in qualitative research.     

Behind the Mirror: Reflective Listening and its Tain in the Work of Carl Rogers

Although Rogerian reflective listening is considered a fundamental therapeutic practice, it is widely misunderstood. This article endeavors to dispel myths about Rogers’ reflective approach through detailed readings of his work, while also opening up a central problematic in Rogers’ thinking. Rogers struggled repeatedly with the dilemma of how the therapist can faithfully reflect the client's experience while avoiding insincerity. The metaphor of a mirror and its tain, or back surface, is used to guide a close analysis of how Rogers grappled with the tension between the therapist's reflective listening process and his or her inner experience while reflecting. It is shown that each of Rogers’ revisions of his conceptualization of reflective listening constitutes a dialectical shift that opens a different approach to the problem of the tain, eventually concluding in an interactional formulation of reflection as the provision of tentative therapist understandings designed to be amended in response to client feedback.     

When Research “Unravels”: One Community Psychologist's Tale of Becoming a Nepantlera

This is an autoethnography of one community psychologist's reflections on the abrupt conclusion of a project that resulted in the dismantlement of a Latinx Student Union at a public middle school in the Pacific Northwest. Gloria Anzaldúa's (Borderlands/La Frontera: The new mestiza, Aunt Lute Books, San Francisco, 2002) notion of nepantla is used to situate how an individual's personal identities often intersects with their professional identities in ways that collide within the research environment. Drawing on the “heart work” core competencies within the field of community psychology (The Community Psychologist, 45, 2012, 8; American Journal of Community Psychology, 55, 2015, 266) and extending the dialogue of feminist community psychologists engaged in narrative work (American Journal of Community Psychology, 37, 2006, 157; American Journal of Community Psychology, 37, 2006, 267; Feminist research practice: A primer, Sage, Los Angeles, 2014; American Journal of Community Psychology, 28, 2000, 883), the author addresses why it is important for researchers of Color engaged in community collaborations to reflect on projects that have unraveled to understand how their positionality shifts within social contexts.
