Paul Ekman and the search for the isolated face in the 1960s.

This essay examines the detailed process of isolating facial data from the context of its emergence through the early work of psychologist Paul Ekman in the 1960s. It explores how Ekman's data practices have been developed, criticized, and compromised by situating them within the political and intellectual landscape of his early career. This essay follows Ekman's journey from the Langley Porter Neuropsychiatric Institute to New Guinea, highlighting his brief but notable collaborations with psychologist Charles E. Osgood and NIH researchers D. Carleton Gajdusek and E. Richard Sorenson. It argues that the different meanings assigned to the human face resulted in how each group developed their studies - examining facial expressions either in interaction, where they shape reciprocal actions in interpersonal communication, or in isolation, where faces surface from the individual's unconscious interior.

Reception of experimental pedagogy and psychology in Chile. Analysis of the intellectual influences of Wilhelm Mann, 1904-1915.

This article provides a detailed analysis of the intellectual research project of Wilhelm Mann, one of the pioneers of experimental and educational psychology in Chile. Mann's work has been the object of so little analysis that his intellectual influences and networks are not clearly known. We analyzed 338 intratext citations from 22 works by Wilhelm Mann published during the period 1904-1915. As a result, we obtained a mapping of his cooperation networks and used a quantitative approach to study the authors who most influenced his career, among whom were William Stern, Herbert Spencer, Wilhelm Wundt, Alfred Binet, and Ernst Meumann. Mann was closely connected to the international and contemporary advances and discussions of his time, despite the lack of infrastructure and difficulties in communication. Mann was the first psychologist to develop a long-term project in Chile that aimed to measure the individualities of Chilean students and their intellectual development.

Brentano's psychology and Kazimierz Twardowski School: implications for the empirical study of psychological phenomena today.

The article presents the most important and almost forgotten theses of Franz Brentano's empirical psychology, which have significance for conceptualization and the method of psychological research. The psychology programme, introduced as early as 1874, remains on the fringes of mainstream empirical psychology, but it was the starting point for Kazimierz Twardowski and his students. The continuation and development of Brentano's thought in the twentieth century can significantly enrich and broaden psychology's theoretical and empirical perspective. This applies primarily to reductionism and the social dimension of mental phenomena.

A little history goes a long way toward understanding why we study consciousness the way we do today.

Consciousness is currently a thriving area of research in psychology and neuroscience. While this is often attributed to events that took place in the early 1990s, consciousness studies today are a continuation of research that started in the late 19th century and that continued throughout the 20th century. From the beginning, the effort built on studies of animals to reveal basic principles of brain organization and function, and of human patients to gain clues about consciousness itself. Particularly important and our focus here is research in the 1950s, 1960s, and 1970s involving three groups of patients-amnesia, split brain, and blindsight. Across all three groups, a similar pattern of results was found-the patients could respond appropriately to stimuli that they denied seeing (or in the case of amnesiacs, having seen before). These studies paved the way for the current wave of research on consciousness. The field is, in fact, still grappling with the implications of the findings showing that the ability to consciously know and report the identity of a visual stimulus can be dissociated in the brain from the mechanisms that underlie the ability to behave in a meaningful way to the same stimulus.

Psychological research and practice in former Yugoslavia and its successors.

This paper presents a brief history of Yugoslav psychology and a review of the current state of psychological research and practice in the former Yugoslav countries. Bibliometric mapping was used to explore the knowledge domain and international visibility of psychological research in Bosnia and Herzegovina, Croatia, North Macedonia, Montenegro, Serbia, and Slovenia. Judging by the number of papers visible in Scopus, psychological research activity in these countries is similar to the other former communist countries. In a relative sense, it is even higher in Slovenia and Croatia. However, psychologists still rely heavily on national journals indexed in Scopus when publishing their papers. Regarding psychological practice, former Yugoslav countries are facing challenges that are more or less typical for all small countries in the global scientific and economic market. Keeping in mind all the obstacles and traumas in the past decades, it should be considered a success that psychology in the former Yugoslav countries is now a fully established profession and a recognized scientific discipline.

A neglected pioneer of psychology: Otto Selz's contribution to the psychology of thinking and the dispute with Gestalt psychologists in Psychological Research/Psychologische Forschung.

In the early decades of the twentieth century, Psychologische Forschung was primarily an outlet for researchers from the school of Gestalt psychology. Otto Selz, whose views were closer to those adopted in the cognitive/information-processing revolution in psychology that began in the 1950s, never published in Psychologische Forschung. However, his work was the subject of a negative evaluation in the journal in a book review by Wilhelm Benary, which was followed by critical assessments published elsewhere by Selz and Karl Bühler of a chapter of Kurt Koffka's. A lengthy rebuttal from Koffka then appeared in Psychologische Forschung. In the present paper, we describe Selz's system and Benary's assessment of it. We then explain the relevant aspects of Koffka's book chapter (in: Dessoir M (ed) Die Philosophie in ihren Einzelgebieten. Ullstein, Berlin, 1925) and the strong critiques of it by Bühler and Selz in 1926, followed by details of Koffka's (Psychol Forsch 9:163-183, 1927) response. This part of the history of psychology is of significance to contemporary psychology on several levels. We have embedded this episode against the historical backdrop of Selz's life and tragic end.

Unconscious inferences in perception in early experimental psychology: From Wundt to Peirce.

What are unconscious inferences in psychology? This article investigates their journey from the early philosophical psychology of Wilhelm Wundt (1832-1920) to the experimental psychology of the American pragmatist Charles S. Peirce (1839-1914). Peirce's reception of Wundt's early works situates him in an international web of 19th-century experimental psychologists and its reconstruction opens new perspectives on the relation between philosophy, psychology, and epistemology. Moreover, this reception testifies to a heretofore overlooked strand of influence of Wundt on North American experimental psychology. The notion of unconscious inferences, of which Hermann von Helmholtz is usually considered the chief exponent, becomes the backbone of Peirce's theory of perception mostly because of the affinity between Wundt's early philosophy of mind and Peirce's logic-mediated approach to psychology.

Twenty-five years of diabetes distress research.

The term 'diabetes distress' first entered the psychosocial research vernacular in 1995, and refers to 'the negative emotional or affective experience resulting from the challenge of living with the demands of diabetes'. At first the proponents of the concept were hesitant in advocating that diabetes distress was a major barrier to individuals' self-care and management of diabetes. Since then, a burgeoning body of evidence, now including several systematic reviews of intervention studies, suggests that diabetes distress, in both type 1 and type 2 diabetes, across ages and in all countries and cultures where it has been studied, is common and can be a barrier to optimal emotional well-being, self-care and management of diabetes. As a consequence, monitoring diabetes distress as part of routine clinical care is part of many national guidelines. The present narrative review summarizes this research and related literature, to postulate the aetiology of diabetes distress, and thus how it may be prevented. The current evidence base for the management of diabetes distress is summarized, and the next steps in the prevention and management of diabetes distress identified.

Looking back on 25 years of the PSAD study group.

The year 2020 marks the 25th anniversary of the Psychosocial Aspects of Diabetes (PSAD) study group of the European Association for the Study of Diabetes. At the time, psychosocial diabetes research in Europe was steadily growing, but not well recognized. By establishing an official European Association for the Study of Diabetes study group, PSAD, for which purpose some hurdles had to be overcome, diabetes psychology became more visible and accessible to the scientific diabetes community. Over the years the PSAD study group has been successful in promoting the quality of research in the field through scientific meetings, mentoring, postgraduate education and publications. Looking back we can conclude that starting the PSAD study group signified an important moment in time, where researchers were joining forces to further the quality of the science, raise awareness of the importance of psychosocial aspects and promote the dissemination of psychological interventions in diabetes care.

How 25 years of psychosocial research has contributed to a better understanding of the links between depression and diabetes.

This narrative review of the literature provides a summary and discussion of 25 years of research into the complex links between depression and diabetes. Systematic reviews have shown that depression occurs more frequently in people with type 1 or type 2 diabetes compared with people without diabetes. Currently, it remains unclear whether depression is also more common in people with impaired glucose metabolism or undiagnosed type 2 diabetes compared with people without diabetes. More prospective epidemiological research into the course of depression and an exploration of mechanisms in individuals with diabetes are needed. Depression in diabetes is associated with less optimal self-care behaviours, suboptimal glycaemic control, impaired quality of life, incident micro- and macrovascular diseases, and elevated mortality rates. Randomized controlled trails concluded that depression in diabetes can be treated with antidepressant medication, cognitive-behavioural therapy (individual, group-based or web-based), mindfulness-based cognitive therapy and stepped care. Although big strides forward have been made in the past 25 years, scientific evidence about depression in diabetes remains incomplete. Future studies should investigate mechanisms that link both conditions and test new diabetes-specific web- or app-based interventions for depression in diabetes. It is important to determine whether treatment or prevention of depression prevents future diabetes complications and lowers mortality rates.

How has psycho-behavioural research advanced our understanding of hypoglycaemia in type 1 diabetes?

Almost 100 years since the discovery of insulin, hypoglycaemia remains a barrier for people with type 1 diabetes to achieve and maintain blood glucose at levels which prevent long-term diabetes-related complications. Although hypoglycaemia is primarily attributable to the limitations of current treatment and defective hormonal counter-regulation in type 1 diabetes, the central role of psycho-behavioural factors in preventing, recognizing and treating hypoglycaemia has been acknowledged since the early 1980s. Over the past 25 years, as documented in the present review, there has been a substantial increase in psycho-behavioural research focused on understanding the experience and impact of hypoglycaemia. The significant contributions have been in understanding the impact of hypoglycaemia on a person's emotional well-being and aspects of life (e.g. sleep, driving, work/social life), identifying modifiable psychological and behavioural risk factors, as well as in developing psycho-behavioural interventions to prevent and better manage (severe) hypoglycaemia. The impact of hypoglycaemia on family members has also been confirmed. Structured diabetes education programmes and psycho-behavioural interventions with a focus on hypoglycaemia have both been shown to be effective in addressing problematic hypoglycaemia. However, the findings have also revealed the complexity of the problem and the need for a personalized approach, taking into account the individual's knowledge of, and emotional/behavioural reactions to hypoglycaemia. Evidence is emerging that people with persistent and recurrent severe hypoglycaemia, characterized by deeply entrenched cognitions and lack of concern around hypoglycaemia, can benefit from tailored cognitive behavioural therapy.

25 Years of psychological research investigating disordered eating in people with diabetes: what have we learnt?

Disordered eating is a serious and under-recognized problem in people with diabetes. This narrative review summarizes the research contributions made by psychological science over the past 25 years to the study of disordered eating in people with type 1 or type 2 diabetes, and identifies gaps and future directions relevant to both healthcare professionals and researchers. Key focus areas of psychological research investigating disordered eating in people with diabetes have been: (1) defining and classifying types of disordered eating; (2) identifying demographic, diabetes-specific and psychosocial correlates of disordered eating, and developing theoretical models of disordered eating in people with type 1 diabetes; (3) identifying the physical and psychosocial consequences of disordered eating; and (4) developing screening measures to identify disordered eating in people with type 1 diabetes. Psychological science has made significant contributions over the past 25 years to our understanding of the nature of this problem and the multiple factors which may interrelate with disordered eating in people with diabetes. Key areas for further attention include: (1) a better definition of disordered eating subtypes in people with type 1 diabetes; (2) characterizing disordered eating in people with type 2 diabetes; and (3) developing multidisciplinary, evidence-based prevention and treatment interventions for comorbid disordered eating and diabetes.

[In quest of objectivity - The concept of reflexology as an attempt towards a mechanistic doctrine of psychics]. / Auf der Suche nach Objektivität ­ das Reflexologie-Konzept als Versuch einer mechanistischen Seelenkunde.

The concept of reflexology had been mainly developed in Russia in the first three decades of the 20th century. It could be regarded as a distinct and universal concept which was to explain both psychic diseases, healthy conditions, and psychology of masses. Moreover, it had been influenced behaviourism and, likewise, was an answer for the search of an objective method for investigation of the psyche. Main protagonists were Vladimir Mikhailovich Bekhterev and Naum Efimovich Ishlondsky (Ischlondsky) whose works underwent international dissemination.

The psychologist's biographer: Writing lives in the history of psychology.

How should historians employ psychological insight when seeking to understand and analyze their historical subjects? That is the essential question explored in this methodological reflection on the relationship between psychology and biography. To answer it, this paper offers a historical, historiographical, and theoretical analysis of life writing in the history of psychology. It touches down in the genres of autobiography, psychobiography, and cultural history to assess how other historians and psychologists have answered this question. And it offers a more detailed analysis of one particularly useful text, Kerry Buckley's (1989) Mechanical Man, to illuminate specific ways in which historians can simultaneously employ, historicize, and critically analyze the theories of the psychologists they study. Although ostensibly about writing biographies of eminent psychologists, this article speaks to a methodological issue facing any historian contemplating the role psychological theories should play in their historical narratives.

Naum Efimovich Ischlondsky: a forgotten protagonist of the concept of reflexology.

The present article reports on the life and work of a protagonist of the concept of reflexology. While the concept itself has its roots in Russia, in Ivan Petrovich Pavlov's research on conditioned reflexes, and was then shaped to a large extent by Vladimir Mikhailovich Bekhterev, the contributions of Naum Efimovich Ischlondsky (Ishlondsky) have been largely forgotten. Moreover, he developed this concept throughout his life up to the 1960s, by which time he was living in the USA. In contrast, in the Soviet Union, the concepts of reflexology based on the work of Bechterev and his followers had already been abandoned by the 1930s for largely political reasons.

'I think' (the thoughts of others). The German tradition of apperceptionism and the intellectual history of schizophrenia.

Although contemporary approaches to schizophrenia pinpoint 'disturbances of the self' as a central aetiological factor, historical insight into the link between accounts of schizophrenia and theories of subjectivity and self-consciousness is poor. This paper aims to overcome this gap by providing the outlines of a largely forgotten but crucial part of the intellectual history of schizophrenia. In particular, the impact of the German tradition of apperceptionism on nineteenth-century accounts of schizophrenia is unearthed. This tradition emerged from German Idealism, and culminated in Emil Kraepelin's account of dementia praecox. In addition to filling an important gap in the historiography of psychiatry, this analysis contributes to ongoing efforts to correct some common misunderstandings regarding Kraepelin's theoretical position.

Janet-Schwartz-Ellenberger: the history of a triangular relationship through their unpublished correspondence (1926-48).

Leonhard Schwartz's importance in the history of psychology has probably not been fully appreciated, and this article is dedicated to the life and work of the Basel neurologist. It highlights the triangular relationship he maintained for 20 years with Pierre Janet, of whom he was a disciple, and Henri F. Ellenberger, to whom he passed on his passion for Janet's oeuvre.

Wild melancholy. On the historical plausibility of a black bile theory of blood madness, or hæmatomania.

Nineteenth-century art historian John Addington Symonds coined the term hæmatomania (blood madness) for the extremely bloodthirsty behaviour of a number of disturbed rulers like Ibrahim II of Ifriqiya (850-902) and Ezzelino da Romano (1194-1259). According to Symonds, this mental pathology was linked to melancholy and caused by an excess of black bile. I explore the historical credibility of this theory of 'wild melancholy', a type of melancholia that crucially deviates from the lethargic main type. I conclude that in its pure form Symonds' black bile theory of hæmatomania was never a broadly supported perspective, but can be traced back to the nosology of the ninth-century physician Ishaq ibn Imran, who practised at the Aghlabid court, to which the sadistic Ibrahim II belonged.

50 years of research sparked by Atkinson and Shiffrin (1968).

In this article we review the framework proposed in 1968 by Atkinson and Shiffrin. We discuss the prior context that led to its production, including the advent of cognitive and mathematical modeling, its principal concepts, the subsequent refinements and elaborations that followed, and the way that the framework influenced other researchers to test the ideas and, in some cases, propose alternatives. The article illustrates the large amount of research and the large number of memory models that were directly influenced by this chapter over the past 50 years.

Sustained Attention to Science: A Tribute to the Life and Scholarship of Joel Warm.

OBJECTIVE: To provide an evaluative synthesis of the life and scientific contributions of the late Joel Warm. BACKGROUND: As the doyen of vigilance research, Joel Warm expanded our understanding and horizons concerning this critical response capacity. However, he also made widespread and profound contributions to many other areas of perception and applied psychology, as we elucidate here. METHOD: Using archival sources, personal histories, and analysis of extant literature documenting Warm's own productivity, we articulate his life in science. RESULTS: Our synthesis illustrates the continued, broad, influential, and expanding impact that one individual can exert on diverse fields of study. Whole bodies of understanding of human behavior have been illuminated by his exemplary career. APPLICATION: By understanding his path to success in applied experimental psychology, we anticipate that others will be motivated, inspired, and guided to replicate and even outstrip a lifetime of such seminal and influential contributions. The presence of individuals such as Warm serves as a primary motive in enhancing Humans Factors/Ergonomics Science.
