Changing Identities to Change the World: Identity Motives in Lifestyle Politics and Its Link to Collective Action

In this article, we assume an interdisciplinary approach to the study of why and how people transpose political considerations to their lifestyles. Our aims are threefold: to understand the meanings and perceptions of people engaged in lifestyle politics and collective action; to examine the motives guiding individual change; and to explore the linkage processes between lifestyle politics and collective action. Identity process theory is considered as a lens to examine the processes and the motives of identity via a thematic analysis of 22 interviews. This study combined interviews with people seeking social change through their lifestyles with interviews with members of action groups and social movements. We found that each participant's identity is guided by identity motives such as distinctiveness, continuity, and psychological coherence. Besides, lifestyle politics is evaluated as an effective way to bring about social change, depending on the individual experience of perceived power to bring about change through collective action. Overall, lifestyle politics states the way in which the participants decided to live, to construct their identities, and to represent their beliefs about the right thing to do. Lifestyle politics complements collective action as a strategy to increase the potential of bringing about social change. The implications of this research are discussed in relation to the importance of understanding the processes of identity and lifestyle change in the context of social, environmental, and political change.     

Attentional bias during emotional processing: evidence from an emotional flanker task using IAPS

Attention is biased towards threat-related stimuli. In three experiments, we investigated the mechanisms, processes, and time course of this processing bias. An emotional flanker task simultaneously presented affective or neutral pictures from the international affective picture system database either as central response-relevant stimuli or surrounding response-uninformative flankers. Participants’ response times to central stimuli was measured. The attentional bias was observed when stimuli were presented either for 1500?ms (Experiment 1) or 500?ms (Experiment 2). The threat-related attentional bias held regardless of the stimuli competing for attention even when presentation time was further reduced to 200?ms (Experiment 3). The results indicate that automatic and controlled mechanisms may interact to modulate the orientation of attention to threat. The data presented here shed new light on the mechanisms, processes, and time course of this long investigated by still largely unknown processing bias.     

Childhood and Adolescent Victimization and Perpetration of Sexual Coercion by Male and Female University Students

This study examines the extent to which male and female university students use verbal sexual coercion and physically forced sex on a dating partner and tests a theoretical model that specifies that corporal punishment, minor forms of neglect by parents, and sexual abuse increase the probability of sexually coercing and sexually assaulting a partner, and that this relationship is partly mediated by antisocial traits and behavior. A path analysis using multinomial logistic regression was used to test the fit of the model to a convenience sample of 13,877 students in 32 nations. Both male and female students perpetrate sexual coercion, but the rates are higher for males. For both men and women, each of the three forms of prior victimization studied were associated with an increased probability of antisocial behavior, which in turn was associated with an increased probability of verbally coercing and physically forcing sex. Most of the direct paths from victimization to sexual coercion were also statistically significant. Because relatively mild victimization such as corporal punishment and seemingly innocuous forms of neglect are highly prevalent, steps to reduce their prevalence could be an import step in primary prevention of sexual coercion.     

Nuevas perspectivas del procesamiento de información

RESUMEN

La Psicología Cognitiva es una de las áreas más pujantes de la Psicología actual. Pese a lo fructífero de esta nueva rama de la Psicología, es necesario formular algunas críticas a este enfoque. Este será el tema principal del presente artículo. Las críticas estarán centradas en las llamadas “analogías formales”. Cuando un dominio de fenómenos es difícil y confuso para nuestra compresión, una solución lícita es establecer algún tipo de analogía entre ese dominio y otro dominio que conocemos mejor. Lo que hemos denominado analogías formales sirven de elementos de vertebración teórica de los datos psicológicos pero, por otra parte, mue stran debilidades importantes. Las principales analogías de la Psicología Cognitiva serán analizadas en este artículo mostrando sus debilidades más importantes.     

Longitudinal study of low and high achievers in early mathematics

Background. Longitudinal studies allow us to identify, which specific maths skills are weak in young children, and whether there is a continuing weakness in these areas throughout their school years. Aims. This 2‐year study investigated whether certain socio‐demographic variables affect early mathematical competency in children aged 5–7 years. Sample. A randomly selected sample of 127 students (64 female; 63 male) participated. At the start of the study, the students were approximately 5 years old (M= 5.2; SD= 0.28; range = 4.5–5.8). Method . The students were assessed using the Early Numeracy Test and then allocated to a high (n= 26), middle (n= 76), or low (n= 25) achievers group. The same children were assessed again with the Early Numeracy Test at 6 and 7 years old, respectively. Eight socio‐demographic characteristics were also evaluated: family model, education of the parent(s), job of the parent(s), number of family members, birth order, number of computers at home, frequency of teacher visits, and hours watching television. Results . Early Numeracy Test scores were more consistent for the high‐achievers group than for the low‐achievers group. Approximately 5.5% of low achievers obtained low scores throughout the study. A link between specific socio‐demographic characteristics and early achievement in mathematics was only found for number of computers at home. Conclusions . The level of mathematical ability among students aged 5–7 years remains relatively stable regardless of the initial level of achievement. However, early screening for mathematics learning disabilities could be useful in helping low‐achieving students overcome learning obstacles.     

Illusory conjunctions in the time domain and the resulting time-course of the attentional blink

Illusory conjunctions in the time domain are errors made in binding stimulus features presented In the same spatial position in Rapid Serial Visual Presentation (RSVP) conditions. Botella, Barriopedro, and Suero (2001) devised a model to explain how the distribution of responses originating from stimuli around the target in the series is generated. They proposed two routes consisting of two sequential attempts to make a response. The second attempt (sophisticated guessing) is only employed if the first one (focal attention) fails in producing an integrated perception. This general outline enables specific predictions to be made and tested related to the efficiency of focal attention in generating responses in the first attempt. Participants had to report the single letter in an RSVP stream of letters that was presented in a previously specified color (first target, T1) and then report whether an X (second target, T2) was or was not presented. Performance on T2 showed the typical U-shaped function across the T1-T2 lag that reflects the attentional blink phenomenon. However, as was predicted by Botella, Barriopedro, and Suero's model, the time-course of the interference was shorter for trials with a correct response to T1 than for trials with a T1 error. Furthermore, longer time-courses of interference associated with pre-target and post-target errors to the first target were indistinguishable.     

Early psychological consequences of the March 11, 2004, terrorist attacks in Madrid, Spain

On March 11, 2004, Al-Qaeda set off 10 bombs on several train routes in Madrid. 192 people were killed and 2,000 wounded. In this study, 1,179 questionnaires were administered Week 2 after the attacks to residents 18 years and over from the affected geographical areas. The questionnaire included items about sociodemographic variables and exposure to the attacks. Psychological effects were assessed as presence of acute stress and depressive symptomatology and functional impairment. 46.7% of the sample presented symptomatology of acute stress and 49.6% depressive symptoms. Among the symptoms of acute stress, the most frequent were re-experiencing (72.5%) and dissociative symptoms (71.8%). The chief predicting variables in symptomatology were being female, over 65 yr. old, and a habitual train user. The large number of affected people was refined with an item analysis and the consideration of severity of interference in psychosocial functioning.     

Lesbian, Gay, and Bisexual Identity Scale (LGBIS): construct validation, sensitivity analyses and other psychometric properties

According to Mohr and Fassinger (2006), identity is seen as both self-identification and collective identification with values, beliefs, traits or behaviours and attachments. Their Lesbian, Gay, and Bisexual (LGB) multidimensional identity model accounts for important variables regarding the constitution of identities. This model not only accesses numerous dimensions of the lives of LGB individuals, but is also based on a body of research that recognizes how LGB difficulties are caused by societal intolerance and marginalization (Mohr & Fassinger, 2000). The Lesbian, Gay, and Bisexual Identity Scale (LGBIS; Kendra & Mohr, 2008) constitutes an operationalization of this multidimensional model, and the aim of this article is to present its construct validity by analysing its factor structure using a sample of Portuguese lesbian, gay and bisexual participants. Results from exploratory and confirmatory factor analyses, as well as from factor invariance analysis across sub-samples are presented. In a general way, the factor structure obtained in this study follows the original proposal of Kendra and Mohr's (2008) LGBIS. Moreover, scale sensitivity analyses are presented in order to check for eventual differences in the factor structure and/or factor intercorrelations regarding participant gender and sexual orientation. These results are then discussed in the light of LGB identity models.     

Preserved learning about allocentric cues but impaired flexible memory expression in rats with hippocampal lesions

Several studies have shown that slight modifications in the standard reference spatial memory procedure normally used for allocentric learning in the Morris water maze and the radial maze, can overcome the classic deficit in allocentric navigation typically observed in rats with hippocampal damage. In these special paradigms, however, there is only intramaze manipulation of a salient stimulus. The present study was designed to investigate whether extramaze manipulations produce a similar outcome. With this aim a four-arm plus-shaped maze and a reference spatial memory paradigm were used, in which the goal arm was marked in two ways: by a prominent extramaze cue (intermittent light), which maintained a constant relation with the goal, and by the extramaze constellation of stimuli around the maze. Experiment 1 showed that, unlike the standard version of the task, using this special training procedure hippocampally-damaged rats could learn a place response as quickly as control animals; importantly, one day after reaching criterion, lesioned and control subjects performed the task perfectly during a transfer test in which the salient extramaze stimulus used during the acquisition was removed. However, although acquisition deficit was overcomed in these lesioned animals, a profound deficit in retention was detected 15 days later. Experiment 2 suggests that although under our special paradigm hippocampal rats can learn a place response, spatial memory only can be expressed when the requisites of behavioral flexibility are minimal. These findings suggest that, under certain circumstances, extrahippocampal structures are sufficient for building a coherent allocentric representation of space; however, flexible memory expression is dependent, fundamentally, on hippocampal functioning.
