Frontal brain asymmetry and reward responsiveness: a source-localization study

The influence of approach and avoidance tendencies on affect, reasoning, and behavior has attracted substantial interest from researchers across various areas of psychology. Currently, frontal electroencephalographic (EEG) asymmetry in favor of left prefrontal regions is assumed to reflect the propensity to respond with approach-related tendencies. To test this hypothesis, we recorded resting EEG in 18 subjects, who separately performed a verbal memory task under three incentive conditions (neutral, reward, and punishment). Using a source-localization technique, we found that higher task-independent alpha2 (10.5-12 Hz) activity within left dorsolateral prefrontal and medial orbitofrontal regions was associated with stronger bias to respond to reward-related cues. Left prefrontal resting activity accounted for 54.8% of the variance in reward bias. These findings not only confirm that frontal EEG asymmetry modulates the propensity to engage in appetitively motivated behavior, but also provide anatomical details about the underlying brain systems.     

South American Children’s Quality of Life: Intra-Urban Disparities along Life-Cycle Indicators

Applied Research in Quality of Life - By 2015, 80% of the population in South America was living in urban areas. Although children in urban areas, on average, enjoy better conditions than children...     

How Do Therapists Understand Their Client’s Problem and Its Resolution: Objectification in Theories of Change

Images and metaphors help to structure the therapist’s belief system in two ways. First, images represent strategies used by therapists in order to simplify the most abstract theoretical concepts. Second, images provide a system according for organizing the information about a client and anticipate the patterns of client change. Within the theoretical frameworks of social representations and of goal directed action theory, the present study explores the metaphorical aspects linked with therapeutic knowledge. This study aims to reconstruct the social representations that therapists use to objectify their theoretical model. The present research relies on a qualitative methodology. The results show that therapists from different orientations rely on different metaphors although, in certain conditions, they tend to share a more general representational system. Implications for psychotherapy training and clinical practice are considered.     

Mental disorders and communication of intent to die in indigenous suicide cases, Queensland, Australia

In comparing Indigenous to non-Indigenous suicide in Australia, this study focussed on the frequency of the association between some psychiatric conditions, such as depression and alcohol abuse, and some aspect of suicidality, in particular communication of suicide intent. Logistic regression was implemented to analyze cases of Indigenous (n = 471) versus non-Indigenous suicides (n = 6,655), using the Queensland Suicide Register as a data source. Compared to non-Indigenous suicides, Indigenous cases had lower odds of being diagnosed with unipolar depression, seeking treatment for psychiatric conditions or leaving a suicide note. Indigenous suicides had greater odds of verbally communicating suicide intent and having a history of alcohol and substance use. The magnitude of these differences is remarkable, underscoring the need for culturally sensitive suicide prevention efforts.     

Using an eye-tracker to assess the effectiveness of a three-dimensional riding simulator in increasing hazard perception

A crucial factor contributing to the high rate of road accidents involving young people is inexperience, in particular the inability to promptly identify risky situations. The aim of this study is to test the effectiveness of a riding simulator in improving this skill in young inexperienced riders. We use the first fixation latency to measure the improvement in detecting the hazardous object. Results show that four training sessions can significantly affect promptness in detecting new hazardous objects as they appear, decreasing the time needed to orient the eyes to the hazard.     

How gender affects the relationship between hedonic shopping motivation and purchase intentions?

Five hundred and fifteen consumer responses are used to model the affect of online hedonic shopping motivation and online purchase intentions: moderated by the consumers' perceptions of their offline and online gendered behaviour. The model was applied across five product categories using confirmatory factor analysis and structural equation modelling. We conclude that there is no online‐gender effect on hedonic shopping motivation and purchase intentions. However, offline‐gendered behaviour does significantly affect hedonic shopping motivation and purchase intentions for females across all product categories. Our findings support the proposition that gender is merely a prosthetic device of the private self and is an intentional manipulation and misrepresentation of the anonymous body. Online gender is a performance that is hidden by the technological veil from the offline space and public self, without social constraints or criticisms. Research implications are discussed.

Atribución de la causalidad y motivación de logro. II: Estudio evolutivo de la influencia de las atribuciones en el nivel manifiesto de motivación de logro

Resumen

Este artículo incluye dos estudios sobre las relaciones entre la motivación de logro y las atribuciones causales realizados desde una perspectiva evolutiva. En ambos se han examinado 180 sujetos, 60 de 1.°, 60 de 3.° y 60 de 5.° de ECB. El primero, como se esperaba, ha mostrado que sólo desde 5.° de EGB las diferencias existentes dentro de cada una de las variables estudiadas se relacionan igual que en ios adultos, siendo más frecuente la atribución de los resultados al «esfuerzo» en el caso de sujetos con alta motivación. Igualmente han aparecido diferencias significativas entre las atribuciones de ambos grupos de sujetos en I.° de ECB a la «dificultad de la tarea», siendo menor este tipo de atribución en caso de motivación baja. Se ha sugerido una explicación para este resultado no esperado. En el segundo estudio, los resultados no han sido concluyentes en relación con la hipótesis propuesta. Ante este hecho se ha sugerido y comentado una posible explicación.     

Estudio sobre la validez de constructo de los cuestionarios MAPE,EAT y ECO

Resumen

Este artículo presenta un estudio sobre la validez de constructo de los cuestionarios MAPE, EAT y ECO. Mediante el análisis de las correlaciones entre las escalas de estos cuestionarios se ponen a prueba los supuestos de distintas teorías sobre las relaciones entre motivos relacionados con el logro, patrones atributivos y expectativas de control. Los resultados son consistentes con la teoría de Dweck y Elliot en la mayoría de los casos. También ponen de manifiesto que la atribución del fracaso a la falta de esfuerzo puede deberse a diferentes causas, dadas las implicaciones psicológicas encontradas, lo que constituye un resultado no esperado. Finalmente, se comentan las implicaciones de los resultados para la investigación y para el uso aplicado de estos cuestionarios.
