The Conception of Synthetic Entities from a Personalist Perspective

Science and Engineering Ethics - Synthetic biology opens up the possibility of producing new entities not found in nature, whose classification as organisms or machines has been debated. In this...     

I will help you because we are similar: Quality of contact mediates the effect of perceived similarity on facilitative behaviour towards immigrants

This research aimed to analyse interpersonal behaviour towards immigrants by exploring related psychosocial variables such as intergroup similarity and quality of intergroup contact. A new interpersonal behavioural tendencies scale was developed. In Study 1, Spanish participants reported their willingness to take different actions towards a Moroccan (i.e. a devalued target, n = 132) or an Ecuadorian (i.e. a valued target, n = 138), perceived intergroup similarity and quality of intergroup contact. Multigroup confirmatory factor analysis identified the expected dimensions: active facilitation (AF), passive facilitation (PF), passive harm (PH) and active harm (AH). Participants reported less similarity, less pleasant contact, less AF and less PF, and more PH with respect to Moroccans relative to Ecuadorians. Quality of contact mediated the effect of perceived similarity on interpersonal behaviour (especially facilitative behaviour) towards immigrants. Study 2 (N = 134) confirmed that this mediation effect also applied to Romanian immigrants, and tested a serial mediation pathway, in which perceived similarity affected symbolic threat, which in turn affected quality of contact, which finally affected behaviour. Changing perceived intergroup similarity might be a way of improving the quality of contact with minority groups, and this would be expected to increase pro‐social behaviour towards such groups.     

A clinician survey of speech and non-speech characteristics of neurogenic stuttering

This study presents survey data on 58 Dutch-speaking patients with neurogenic stuttering following various neurological injuries. Stroke was the most prevalent cause of stuttering in our patients, followed by traumatic brain injury, neurodegenerative diseases, and other causes. Speech and non-speech characteristics were analyzed separately for these four etiology groups. Results suggested possible group differences, including site of lesion and influence of speech conditions on stuttering. Other characteristics, such as within-word localization of disfluencies and presence of secondary behaviors were comparable across the etiology groups. The implications of our results for the diagnosis of neurogenic stuttering will be discussed.

Educational objectives: After reading this article, the reader will be able to: (1) provide a concise overview of the main literature on neurogenic stuttering; (2) discuss the speech and non-speech characteristics of neurogenic stuttering; (3) provide an overview of current clinical practices for intervention with neurogenic stuttering patients and their perceived outcome.     

Suicide attempts and family history of suicide in three psychiatric populations

The influence of a family history of suicide on suicide attempt rate and characteristics in depression, schizophrenia, and opioid dependence was examined. One hundred sixty inpatients with unipolar depression, 160 inpatients with schizophrenia, and 160 opioid-dependent patients were interviewed. Overall, a family history of suicide was associated with a higher risk for suicide attempt, with high-lethality method, with repeated attempts, and with number of attempts, while the interaction between family history and diagnostic group was not significant. Thus, a positive family history of suicide was a risk factor for several suicide attempt characteristics independent of psychiatric diagnosis.     

Influence of education on the benton visual retention test performance as mediated by a strategic search component

Age-related cognitive decline has been reported by several studies. However, little investigations have dealt with the effect of education on this decline. In the present study, we examined the influence of educational level on visual working memory, evaluated by the Benton Visual Retention Test (BVRT in recognition format) in 829 elderly participants of the PAQUID study. A multivariate linear model suggested that the effect of education on BVRT performance was not mediated by visual discrimination abilities suggesting that it was mainly supported by better executive abilities. Moreover, the analysis of success and error location suggested that subjects with higher educational level use a more exhaustive exploration strategy during the recognition phase than subjects with lower educational level, which permit them to better perform. The ability of high educational level subjects to use more efficient strategies may participate to the 'cognitive reserve' capacity.     

Predicting Environmental Behaviors: The Influence of Self-Determined Motivation and Information About Perceived Environmental Health Risks1

The purpose of the present study is to examine the combined contribution of 2 predictors of environmental behaviors, self-determined motivation and information about a particular environmental issue (viz., perceived environmental health risks). The hypothesized model was tested with 761 participants from the general population using structural equation modeling. Self-determined motivation was found to predict both environmental behaviors and the tendency to seek information on health risks coming from 2 main sources (federal government agencies and public groups), which led to more confidence in those sources of information. In turn, confidence in the different sources of information was found to be significantly associated with perceptions of environmental health risks. Finally these perceptions were also found to be predictors of environmental behaviors. Results are discussed in terms of 2 possible processes that could facilitate environmental behaviors.     

Stable individual differences in situation-behaviour,construct-behaviour,and goal-behaviour relations

This study starts from a cognitive-social-learning conceptualization of the contribution of static person by situation interaction to overt behaviour variance. Individual differences in the relation between, on the one hand, situational variation in behaviour and, on the other hand, situational variation in objective situational characteristics, situational variation in construed situational characteristics, and situational variation in goals-in-situations were systematically investigated. Thirty-six first-year psychology students had to freely generate and briefly describe 20 interpersonal situations that they had encountered during the last year. Afterwards, they had to rate each situation for four basic behavioural continua, eight supplied objective situational characteristics, eight supplied constructs, and eight supplied goals. Correlational analysis revealed many stable individual differences, not only in degree, but also in direction (sign) of situation-behaviour, construct–behaviour, and goal–behaviour relations. These relational variables could be reduced to seven relational factorial dimensions. The theoretical and practical implications of these findings are discussed.
