A Case Study of Liberation Among Latino Immigrant Families Who Have Children with Disabilities

Latino immigrant families with children with disabilities experience multiple sources of oppression during their settlement process in the United States. Unfair social structures and dominant cultural values and norms and the way they influence the immigrants' personal life stories generate a cycle of oppression very difficult to break. This paper presents a case study of how a group of Latino parents carried out a process of liberation fueled by the generation of empowering community narratives (critical awareness leading to transformative action) that resulted from a community-university partnership. Participants initiated a process that led them to discover their own stories of oppression and create new stories; to deconstruct the dominant cultural narratives and modify existing ones; and to understand contexts for power sharing. This joint reflection and increased awareness propelled group members to take action by founding a grassroots organization to redress some of the injustices that were partly responsible for their oppression, thus generating shifts at the personal, relational, and collective levels. In light of the theory of liberation, we discuss the participants' development of critical awareness that led them to take action to address their unmet needs.     

Modeling the neurological control of human movements

Although computer models have been extensively used in recent years to understand the way physical systems operate and interact, the enormous power of mathematical modeling and computer simulations has been difficult to implement for the benefit of neuroscientists studying the human motor control system. Nevertheless, homeomorphic models are now being used to explain and predict the neural and biomechanical aspects of different human movements. This paper argues for the importance of regarding model simulations as a supplementary approach to traditional methods of experimental investigation by drawing examples from both the experimental and the modeling literature. The discussion focuses on studies of the triphasic control signal for fast, goal-directed movements and on aspects of sampled data control for slow, tracking movements. The aim of this viewpoint article is to promote a more widespread use of modeling and simulation in the field of motor control.     

Fear of victimization in Mexico

The aim of this study was to explore the influence on Mexican citizens of several variables that have been reported as being important in the literature on fear of victimization. Sociodemographic variables such as gender, age group and socioeconomic level, together with perceived risk of victimization, perceived seriousness in the face of different acts, experienced victimizations and perception of control of violence and crime are included among these variables. One hundred and eighty-one people were interviewed in a cross-sectional field study. Multiple regression analyses were carried out in three fear of victimization dimensions: personal, property and general situations. On the whole, the findings confirm the influence of the aforesaid variables. Being a woman, feeling at risk of being the object of violent attacks and the seriousness with which moderately violent acts are perceived were some of the major variables considered to predict fear of victimization.     

Occasion setting and drug tolerance

There is considerable evidence that drug-paired cues become associated with drug effects. It has been hypothesized that these cues act as Pavlovian conditional stimuli (CSs), and elicit conditional compensatory responses that contribute to tolerance. On the basis of a conditioning analysis of tolerance, we would expect that is should be possible to establish drug-paired cues as occasion setters, as well as conditional stimuli. Using feature-positive discrimination training, we evaluated the contribution of occasion-setting stimuli (as well as CSs) to tolerance to the hypothermic effect of ethanol in rats. The results indicated that a complete associative analysis of drug tolerance should incorporate not only the CS properties of predrug cues, but also the occasion-setting properties of such cues. The findings have implications for interpreting conflicting findings concerning extinction of tolerance and for cue-exposure treatments of addiction.     

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.     

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.     

Well‐being in cross‐cultural transitions: discrepancies between acculturation preferences and actual intergroup and intragroup contact

Two studies examined the effect of acculturation–contact discrepancies on well‐being. Specifically, we tested the prediction that well‐being will be compromised when cultural minorities' acculturation preferences are not met by the intergroup and intragroup contact in a new society. Study 1 found that for Polish immigrants (n = 55) acculturation–contact discrepancies were associated with compromised well‐being. Study 2 followed a cohort of international students (n = 106) for a period of two academic years. Results suggested that discrepancies in students' acculturation–contact in their first year had harmful consequences for their well‐being 1 year later. Overall, the two studies show that discrepancies between acculturation preferences and actual contact have negative implications for the psychological adaptation of acculturating individuals.
