Family identity and severe mental illness: A thematic synthesis of qualitative studies

There is a growing amount of research showing that a shared social identity and the sense of belonging to a family have a potential effect on health. However, little is known about the effects of severe mental illness on family identity. The authors carried out this thematic synthesis based on a systematic review of literature on family narratives of severe mental illness and family identity. The main findings indicate that in many families (i) their identity—as a shared social identity—undergoes a transformation process by which the identity aspects of being a family are reinforced; (ii) family members often take on a caring role as their main family role; and finally, (iii) a cultural component shapes this transformation process. The authors describe implications for research and application in the mental health field. All in all, family identity is transformed by the experience of severe mental illness.     

Pragmatics of the Development of Personal Identity in Adolescents in the Latin American Context

The present work proposes a pragmatic perspective of the development of personal identity. Such perspective is based on a unifying vision that incorporates the contribution of communicative pragmatics and becomes aware of the contribution of semiotics to psychology, without leaving aside the eriksonian point of view and other significant contributions in the field. The article defines identity in adolescence from a development approach, and adopts a systemic perspective concerning the insertion of adolescents in their context of formation as individuals. It then proposes a way to understand identity from a pragmatic-communicative perspective. Finally, it introduces two communicative use contexts from which personal identity can emerge, showing the importance of communication and language in the formation and development of identity.     

The mental representation of numerical fractions: real or integer?

Numerical fractions are commonly used to express ratios and proportions (i.e., real numbers), but little is known about how they are mentally represented and processed by skilled adults. Four experiments employed comparison tasks to investigate the distance effect and the effect of the spatial numerical association of response codes (SNARC) for fractions. Results showed that fractions were processed componentially and that the real numerical value of the fraction was not accessed, indicating that processing the fraction's magnitude is not automatic. In contrast, responses were influenced by the numerical magnitude of the components and reflected the simple comparison between numerators, denominators, and reference, depending on the strategy adopted. Strategies were used even by highly skilled participants and were flexibly adapted to the specific experimental context. In line with results on the whole number bias in children, these findings suggest that the understanding of fractions is rooted in the ability to represent discrete numerosities (i.e., integers) rather than real numbers and that the well-known difficulties of children in mastering fractions are circumvented by skilled adults through a flexible use of strategies based on the integer components.     

Exercise commitment and proneness to eating disorders in a group of physical education teachers

The study examined the association of exercise commitment with proneness to eating disorders in 50 physical education teachers who had been practicing various aerobic sports at least three times a week for at least 5 years. Significant coefficients were found between Commitment to Exercise Scale scores, the number of weekly training sessions, and scores on the Eating Disorders Inventory-2 scales measuring Maturity Fears, Social Insecurity, Perfectionism, and Asceticism. However, no relationship was found between the Commitment to Exercise Scale and the Eating Disorders Inventory-2 variables measuring anorexic tendencies (such as Drive for Thinness, Body Dissatisfaction, and Bulimia). Findings suggest the presence of some psychological factors common to both anorexic tendencies and excessive exercising but not complete overlap, so a rather more complex pattern of relationships appears to be mediated by sex and personality characteristics.     

Self-Construction,Cognitive Conflicts,and Disordered Eating Attitudes in Young Women

The aim of this study is to identify cognitive variables that predict disordered eating attitudes in a nonclinical sample composed of 50 female university students. Repertory grid technique was used to assess cognitive features of self-construing and cognitive conflicts. Drive for Thinness and Body Dissatisfaction scales from the Eating Disorder Inventory–2 were used as dependent variables, as previous studies suggested that high scores on these scales are associated with the risk of developing or aggravating eating syndromes. Results suggest that drive for thinness can be associated with cognitive conflicts, whereas body dissatisfaction may be higher for those who construct themselves as inadequate and similar to others. In addition, both dependent variables were predicted by being younger and having a higher body mass index.     

A Simon effect for depth in three-dimensional displays

We investigated whether the Simon effect occurs for the depth dimension in a 3-dimensional display. In Experiment 1, participants executed discriminative responses to 2 stimuli, a cross and a sphere, both 3-dimensional, which were perceived to be located near or far with respect to the participant's body. The response keys were located near and far along the participant's midline. Apparent stimulus spatial location (near or far) was irrelevant to the task. Results showed a depth Simon effect, attributable to the apparent stimulus spatial location. Experiment 2 replicated Experiment 1 with a different procedure. The 2 stimuli, a triangle and a rectangle, were 2-dimensional and were perceived as being located near or far from the participant's midline; the response keys were located near and far along the participant's midline. Results showed again the depth Simon effect. Experiment 3 was a control condition in which the 2 stimuli, drawings of a lamp and of a chair, had the same size, regardless of whether they appeared to be near or far. The depth Simon effect was replicated. A distribution analysis on data of Experiment 3 showed that the Simon effect increased as reaction times became longer. In Experiment 4, the position of the 2 stimuli, a circle and a cross, varied on the horizontal (right or left) dimension, whereas the position of the 2 responses varied along the depth (near or far) dimension. No Simon effect was found.     

Comparison processes on visual mental images

Three experiments were conducted to test whether visual mental images and visual perceptual representations possess equivalent structural properties and undergo functionally equivalent comparison processes. In Experiment 1, subjects were required to perform asame-different letter classification in which the two letters were shown in succession. The first letter in the pair either was actually presented (perceptual condition) or had to be actively generated (imaginal condition). Both conditions showed that (1) response latencies fordifferent decisions decreased as a function of the degree of difference (segment effect), and (2) same decisions were faster than the fastestdifferent ones (fast same effect). In Experiment 2, the imaginal condition only was employed, but no imagery instructions were given and very strict time constraints were assigned. In spite of these restrictions, subjects apparently generated and used visual images, as attested by the fact that the results were comparable to those of the previous experiment. In Experiment 3, three experimental manipulations were introduced to prevent the use of visual images. Such manipulations proved effective, as shown by the disappearance of the segment effect. It was concluded that in the visual modality images and percepts are equivalent in structure and are processed in a very similar way.     

Can linguistics contribute to the study of verbal behavior?

A number of publications during the last decade reveal a growing interest in linguistics and psycholinguistics among some radical behaviorists, who have proposed a direct rapprochement between a formal analysis of language and a functional account. It is argued that whereas function has to do with the circumstances under which verbal behavior is emitted, structure has to do with its "internal organization," the ways in which sentences or parts thereof are presumably interrelated. These are said to be different dimensions of verbal behavior; together they should lead toward a coherent psychology of language. But psychologists bent on incorporating techniques from linguistics should be aware of its underlying assumptions, lest their work be deflected in essentially unproductive directions. The line between rapprochement and subservience is thin indeed, as the extant literature shows. This paper traces the development of mainstream contemporary psycholinguistics and examines the linguist's assumptions about the subject matter in the light of a behavioral analysis. The possibility of an effective reconciliation seems to be a long way off.
