Resistance to extinction of conditioned electrodermal responses: a study of the incubation fear hypothesis

In the present study we examined Eysenck's incubation hypothesis of fear. Probability of skin conductance response (SCR) was analyzed for a sample of 79 undergraduate women, ranging in age from 18 to 25 years. Different groups of participants were conditioned to two levels of unconditioned stimuli (UCS) intensity and presented to three levels of unreinforced conditioned stimuli (CS) exposures (extinction phase) in a delay differential conditioning paradigm. The CSs were fear-relevant slides (snakes and spiders) and the UCSs were aversive tones. Analysis did not show a clear incubation effect; instead an increased resistance to extinction of SCR probability in association to the high-UCS and the short unreinforced CS presentation was evident. Findings support partially Eysenck's incubation theory of fear/anxiety.     

Sociopolitical development of female migrant domestic workers in Southern Spain: A qualitative study of a pathway against injustice

Domestic work is a sector characterized by various forms of injustice, prompting some women to embark on a pathway towards activism. Based on the Sociopolitical Development (SPD) framework, this study aims to explore female Latin American migrants' experiences of injustice in the domestic work sector in Spain and how they challenge them, particularly when they become involved in organized collective action. To this end, in-depth interviews were conducted with 11 women of Latin American origin who actively participate in the Association of Domestic Workers of Seville. The qualitative analysis found that being a domestic worker, having experiences of exploitation, discovering rights, receiving rights training, sharing stories of oppression, and engaging in sociopolitical actions are key experiences in guiding migrant women from the acritical and adaptive stages of SPD towards the pre-critical, critical, and liberation ones. Knowledge about these significant life-changing events may be useful for designing interventions aimed at fostering different ways in which oppressed groups can challenge injustice.     

Computerized hypertextual strategy and personal construction of meaning

The aim of this study is to provide information about the effects of strategic training in the area of social sciences (1) on the real level, as well as perceived competence in terms of the students' skills to select, organise and produce information; and (2) on their attitude and motivation towards working in this area of the curriculum. 107 students took part in this study, 57 of whom were the control group and 50 the experimental one. They were all enrolled in the third year of secondary school (9th year). The teachers and students who took part in this experience followed an on-line course to manage the strategy for approximately three months. Subsequently, the teacher introduced the tool in class, applying it both from a conceptual and a procedural point of view. The results show that the strategic training implemented in this study greatly improved written understanding procedures (both literal and inferential), increased perceived competence to manage internal information (selection, organization, and elaboration), and generated positive changes in terms of students' attitude and motivation towards working in the area of social sciences.     

The impact of verbal instructions on goal-directed behaviour

It is common to use verbal instructions when performing complex tasks. To evaluate how such instructions contribute to cognitive control, mixing costs (as a measure of sustained concentration on task) were evaluated in two task-switching experiments combining the list and alternating runs paradigms. Participants responded to bivalent stimuli according to a characteristic explicitly defined by a visually presented instructional cue. The processing of the cue was conducted under four conditions across the two experiments: Silent Reading, Reading Aloud, Articulatory Suppression, and dual mode (visual and audio) presentation. The type of cue processing produced a substantial impact on the mixing costs, where its magnitude was greatest with articulatory suppression and minimal with reading aloud and dual mode presentations. Interestingly, silently reading the cue only provided medium levels of mixing cost. The experiments demonstrate that relevant verbal instructions boost sustained concentration on task goals when maintaining multiple tasks.     

Response preparation in Parkinson's disease: automatic vs. controlled processing

Using a finger cuing paradigm, we investigated response preparation in Parkinson's disease (PD). The central question was whether PD individuals are differentially affected by preparatory cues that specify a more automatic response set configuration (that induces within-hand preparation) as opposed to a more controlled one (that induces between-hands preparation). Reaction times (RTs) and error rates were measured in 20 non-demented individuals with PD and 20 healthy control participants with a long and short preparation interval (500 ms and 2000 ms). RT benefits and/or costs were measured for cues indicating a within- and between-hands motor preparatory set. Overall, RTs were significantly longer, and errors more frequent, for PD participants than for control participants. More importantly, in comparison with control subjects, PD individuals showed a significant deficit in between-hands preparation but not in within-hand preparation. Furthermore, longer preparation intervals slowed down cued RTs of the control participants, but not those of the PD individuals. Together, these findings suggest that whereas automatic response preparation processes are spared in PD, controlled response preparation processes operate at a slower rate and/or are delayed in time.     

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.     

SA-45: a brief form of the SCL-90

The Symptom Assessment-45 Questionnaire (SA-45) is a 45-item self-report instrument of psychiatric symptomatology derived from the original SCL-90. The SA-45 consists of nine 5-item scales assessing each of the same symptom domains as its parent instrument with no item overlap across domains. This paper provides preliminary validation of the Spanish version of the questionnaire in an undergraduate sample. Exploratory and confirmatory factor analyses supported a 9-factor structure, which corresponds to the nine proposed scales. Normative data, reliability (internal consistency) and validity were also examined, finding support for sound psychometric properties.     

The consolidation of object and context recognition memory involve different regions of the temporal lobe

These experiments investigated the involvement of several temporal lobe regions in consolidation of recognition memory. Anisomycin, a protein synthesis inhibitor, was infused into the hippocampus, perirhinal cortex, insular cortex, or basolateral amygdala of rats immediately after the sample phase of object or object-in-context recognition memory training. Anisomycin infused into perirhinal or insular cortices blocked long-term (24 h), but not short-term (90 min) object recognition memory. Infusions into the hippocampus or amygdala did not impair object recognition memory. Anisomycin infused into the hippocampus blocked long-term, but not short-term object-in-context recognition memory, whereas infusions administered into the perirhinal cortex, insular cortex, or amygdala did not affect object-in-context recognition memory. These results clearly indicate that distinct regions of the temporal lobe are differentially involved in long-term object and object-in-context recognition memory. Whereas perirhinal and insular cortices are required for consolidation of familiar objects, the hippocampus is necessary for consolidation of contextual information of recognition memory. Altogether, these results suggest that temporal lobe structures are differentially involved in recognition memory consolidation.     

Enhancing challenged students' recognition of mathematical relations through differential outcomes training

Previous studies have reported that the differential outcomes procedure enhances learning and memory in special populations with cognitive deficits (see Goeters, Blakely, & Poling, 1992, for a review). In the present study we extend these findings to healthy adults who were asked to discriminate between the symbols " > " and " < " in mathematical statements. In Experiment 1, the performance of participants who showed difficulties in discriminating between these symbols was better (shorter response times) for the differential outcomes condition than for the nondifferential outcomes condition. In Experiment 2, the difficulty of the task was increased by using signed decimal numbers. Similar to Experiment 1, participants who initially had difficulties in discriminating between the symbols showed better performance (higher accuracy) for the differential outcomes condition than for the nondifferential outcomes condition, but only when both numbers were negative. These findings suggest that the differential outcomes procedure can be used to improve performance of challenged healthy adults on discrimination tasks with mathematical symbols and relations.     

Evaluation of violent behaviors in secondary school

School harassment, or bullying, is a term that for being so frequent already forms a part of our vocabulary. In the present work one presents a new instrument of evaluation of the violence that happens in the school centers. The Questionnaire of School Violence (CUVE) has been elaborated and, later, applied to a sample of 1637 teenagers of seven centers of Secondary Obligatory Education (public and compound). The CUVE evaluates in a trustworthy way five dimensions of the school violence: a) physical indirect violence on the part of the student body; b) verbal violence of the student body towards companions; c) physical direct violence between (among) pupils; d) verbal violence of the student body towards the professorship; and e) violence of the professorship towards the student body.
