Determinants of linear judgment: a meta-analysis of lens model studies

The mathematical representation of E. Brunswik's (1952) lens model has been used extensively to study human judgment and provides a unique opportunity to conduct a meta-analysis of studies that covers roughly 5 decades. Specifically, the authors analyzed statistics of the "lens model equation" (L. R. Tucker, 1964) associated with 249 different task environments obtained from 86 articles. On average, fairly high levels of judgmental achievement were found, and people were seen to be capable of achieving similar levels of cognitive performance in noisy and predictable environments. Further, the effects of task characteristics that influence judgment (numbers and types of cues, inter-cue redundancy, function forms and cue weights in the ecology, laboratory versus field studies, and experience with the task) were identified and estimated. A detailed analysis of learning studies revealed that the most effective form of feedback was information about the task. The authors also analyzed empirically under what conditions the application of bootstrapping--or replacing judges by their linear models--is advantageous. Finally, the authors note shortcomings of the kinds of studies conducted to date, limitations in the lens model methodology, and possibilities for future research.     

Flow and Happiness in Later Life: An Investigation into the Role of Daily and Weekly Flow Experiences

Fifty-four older adults ranging in age from 70 to 86 years old (M = 77.54) reported daily levels of positive and negative affect, life satisfaction and daily activities for seven consecutive days. Hierarchical linear modeling (HLM) was used to investigate inter- and intra-individual effects of flow experiences on affect. Higher quality of flow was positively associated with high arousal positive affect (i.e., feeling peppy, enthusiastic, happy), negatively associated with low arousal negative affect (i.e., feeling sad and disappointed), and positively associated with life satisfaction. However, more frequent flow experiences throughout the week predicted lower average levels of positive affect and life satisfaction. Overall, the results demonstrate that flow is linked to the affective experiences of older adults, and that an individual’s overall propensity to experience flow may be influential beyond the immediate effects of a given flow experience.     

Data from Russian Help to Determine in Which Languages the Possible Word Constraint Applies

The Possible Word Constraint, or PWC, is a speech segmentation principle prohibiting to postulate word boundaries if a remaining segment contains only consonants. The PWC was initially formulated for English where all words contain a vowel and claimed to hold universally after being confirmed for various other languages. However, it is crucial to look at languages that allow for words without vowels. Two such languages have been tested: data from Slovak were compatible with the PWC, while data from Tarifiyt Berber did not support it. We hypothesize that the fixed word stress could influence the results in Slovak and report two word-spotting experiments on Russian, which has similar one-consonant words, but flexible word stress. The results contradict the PWC, so we suggest that it does not operate in the languages where words without vowels are possible, while the results from Slovak might be explained by its prosodic properties.     

Revisiting Anna O.: a case of chemical dependence

The famous clinical case of Anna O./Bertha Pappenheim, who was treated by Breuer from 1880 to 1882 and whose pathology was discussed by him and Freud in an 1895 article (J. Breuer & S. Freud, 1895/1955), is reviewed based on biographical information regarding the patient, which appeared from 1953 onward. The objective of this article is to show that, in order to better understand the case, the diagnosis of chloral hydrate and morphine dependence, as well as that of mood disorder (primary or drug induced), has to be taken into account. The method used is a careful literature review. The conclusion is that, based on all available data disclosed in recent years, these 3 diagnoses should be considered in this case, which is the most studied one in the history of psychoanalysis.     

Sustained and transient modulation of performance induced by emotional picture viewing

We investigated how viewing task-irrelevant emotional pictures affects the performance of a subsequent nonemotional visual detection task. Subjects performed target-detection trials following the offset of individual unpleasant, pleasant, and neutral pictures. Sustained interference occurred when subjects viewed unpleasant pictures (mutilated bodies) in a sequential, "blocked" fashion. Such slowing down of reaction time appeared to build up with time, consistent with the instatement of a defensive emotional state. With a randomized picture presentation, only a transient interference effect was observed, consistent with increased attentional demands during the processing of unpleasant pictures. During blocked presentation of affiliative pleasant pictures, reaction times were faster, suggesting the activation of appetitive motivational systems. Ultimately, both attentional and motivational systems are intricately tied in the brain and, together, determine behavior.     

Isatin: role in stress and anxiety

(Indoledione 2,3) isatin is an endogenous indole found both in mammalian brain and peripheral tissues. Isatin concentration in blood can exceed 1 microM and tissue concentrations vary from < 0.1 to 10 microM. Its level in the brain and periphery is increased by stress. Isatin has a wide spectrum of behavioural and metabolic effects. It is anxiogenic at lower doses and sedative at higher doses. Its most potent known in vitro actions are as an antagonist of atrial natriuretic peptide (ANP) function and NO signaling. In this review, we discuss isatin and stress in animal models, the few human studies, and also what it is known to date about the molecular mechanisms of its action. We suggest the possibility that isatin and its analogues may be interesting new pharmacological agents; Isatin antagonists may be anxiolytic, and isatin agonists may activate the HPA axis.     

Ukrainian Application of the Children's Somatization Inventory: Psychometric Properties and Associations With Internalizing Symptoms

This paper examines the psychometric properties of the Children's Somatization Inventory (CSI) in 600 10–12-year old children in Kyiv, Ukraine, replicating and extending the original findings from a sample in Nashville, Tennessee (J. Garber et al. 1991). The Kyiv children had significantly lower CSI total scores and reported significantly fewer symptoms than the American children. The Kyiv mothers, however, reported significantly more somatization symptoms in their children than did the American mothers. A factor analysis of the children's data yielded four similar factors encompassing pseudoneurologic, cardiovascular, gastrointestinal, and pain/weakness symptoms. Consistent with the findings from the Nashville study, the CSI was significantly related to the children's self-reports of health and depressive and anxiety symptoms and to maternal reports of child depression and anxiety symptoms. In addition, although more children with the highest CSI scores (25+) reported various illness experiences than those with 0–1 symptoms, no differences were found in the school absentee records. Thus, the results were congruent with the findings of the Nashville study, indicating that the CSI reliably measured somatization in this Ukrainian sample.     

Eating disorders in the course of life: A qualitative approach to vital change

Eating disorders (EDs) have become one of the biggest mental-health problems in the last decades, especially among youth and women. The present study aims to analyse the suitability of Prochaska and DiClemente’s Transtheoretical Model of Change when applied to the living experiences of people diagnosed with ED and their carers. For this purpose, we applied a narrative biographic approach to the ways in which people face their problems and vital development in the ED domain. Through the narrative analysis of these autobiographies, we aimed to study the patients’ own notions of ‘change’, ‘problem’ and ‘vital trajectory’. We focused on five autobiographic interviews of persons diagnosed as ED (four women and a man). The analysis yields three discourses which organize and give sense to our participants’ vital transitions: a discourse of functional adaptation to events and experiences; one that pays attention to random events and people entering your life; and one that has the personal initiative and agency of an individual agent at its core. It also illuminates particular ways of understanding determination, contemplation and pre-contemplation. These ways of understanding change are shown to extend the possible ways of thinking about people’s lives and ED patients’ perspectives.     

Predicting the Presence and Search for Life Meaning: Test of an Attachment Theory-Driven Model

To date, little is known about how perceptions of life meaning are formed, although recent evidence suggests that “basic attitudes about the meaning of existence are commonly rooted in evolved biological factors and conjointly influenced through people’s experiences with life” (Steger et al. in J Posit Psychol 6:181–191, 2011a). In line with this view, we proposed that multidimensional aspects of adult attachment security and trait authenticity would independently predict perceptions regarding the presence and search for life meaning. Correlational findings largely supported hypothesized relationships among these variables. Regression findings further demonstrated that adult attachment orientations and trait authenticity uniquely predicted the presence of life meaning, and made more modest contributions to the search for meaning. In both predictions, experiences of self-alienation appeared to function as a mediator of the relationship between attachment security and meaning in life perceptions. Implications of our findings for advancing understanding of the formation of these perceptions are discussed.
