A HyperCard program to track information-search strategies

In many decision-making studies, subjects are given a body of material to review and then their search strategies are assessed. Research paradigms in such studies exhibit varying degrees of artificiality and obtrusiveness, and data collection is often cumbersome. The present paper describes a Macintosh application using the Hyper-Card program that tracks subjects’ search strategies in a less obtrusive and artificial manner than those used in previous studies. The program records the order in which the material is reviewed as well as the duration of subjects’ access to each part of the material. Data collection is also greatly simplified by the program. An experiment using the program is described and suggestions for other uses of the program are discussed.     

Stereotypes in Persuasive Communication: Influence Exerted by a Disapproved Source

The present paper examines how someone's use of stereotypes can exert influence over others' judgments. In the 2 studies reported here, participants were presented with messages containing information provided by a source. In Study 1, the source was an in-group member. The messages were manipulated in a between-subjects design so that participants were either given stereotypical or counterstereotypical information. After being given a hint regarding the source's estimate, participants were asked to provide their own estimates about a number of points displayed on a computer screen. Results indicate that participants tended to use as an anchor the estimate provided by the source that made use of stereotypes. In Study 2, an out-group member provided participants with information that was either stereotypical or neutral. Again, results indicate that participants were influenced by the source making use of stereotypes.     

Evaluating the therapeutic use of photocards in European prisons

This paper focuses on the evaluation of the therapeutic use of photocards by prisoners and facilitators in a counselling psychology led European project, based on responses to open-ended questionnaires. It is part of a wider project, involving seven partner organisations in six European countries (England, Finland, Greece, Italy, Malta and Romania), which developed and trialled four different approaches to using photography in the context of counselling in prisons. Of the 51 inmates that participated in the project, 48 (94%) completed the questionnaires; of those, 39 (77%) were available for individual analysis due to prison restrictions in one partner organisation only allowing group data. Of those 39, who returned their completed questionnaires, over 92% found the therapeutic use of photographs either very helpful (56.4%) or helpful (35.9%), and the remaining 7.7% described it as average. From the thematic analysis, main themes emerging regarding inmates’ experiences of working with photocards were that it: facilitates emotional expression and sharing; unlocks memories and reconnects with life outside; fosters insight, reflection and self-growth; breaks the monotony of prison life and, overall aids emotional learning. A thematic analysis of 11 psychological therapists/facilitators’ perspectives showed that the use of photocards: gives clients a voice; provides a safe and collaborative frame and a therapeutic relationship; and, provides a useful icebreaker, helpfully overcoming anxieties of both client and psychotherapist/facilitator. Overall, photocards were considered useful as their projective nature can help facilitate prisoners’ strong need for expression in a context where there are limited opportunities and trust is fragile.     

Electrophysiological evidence of perceived sexual attractiveness for human female bodies varying in waist-to-hip ratio

The dynamics of brain activation reflecting attractiveness in humans are unclear. Among the different features affecting attractiveness of the female body, the waist-to-hip ratio (WHR) is considered to be crucial. To date, however, no event-related potential (ERP) study has addressed the question of its associated pattern of brain activation. We carried out two different experiments: (a) a behavioural study, to judge the level of attractiveness of female realistic models depicting 4 different WHRs (0.6, 0.7, 0.8, 0.9) with and without clothes; (b) an EEG paradigm, to record brain activity while participants (heterosexual men and women) viewed these same models. Behavioural results showed that WHRs of 0.7 were considered more attractive than the others. ERP analyses revealed a different pattern of activation for male and female viewers. The 0.7 ratio elicited greater positivity at the P1 level in male viewers but not females. Naked bodies increased the N190 in both groups and peaked earlier for the 0.7 ratio in the male viewers. Finally, the late positive component (LPC) was found to be greater in male than in female viewers and was globally more marked for naked bodies as well as WHRs of 0.7 in both groups of viewers. These results provide the first electrophysiological evidence of specific time periods linked to the processing of a body feature denoting attractiveness and therefore playing a role in mate choice.     

Effects of repetitive stress during the acute phase of Trypanosoma cruzi infection on chronic Chagas' disease in rats

The effect of repetitive stress during acute infection with Trypanosoma cruzi (T. cruzi) on the chronic phase of ensuing Chagas' disease was the focus of this investigation. The aim of this study was to evaluate in Wistar rats the influence of repetitive stress during the acute phase of infection (7 days) with the Y strain of T. cruzi on the chronic phase of the infection (at 180 days). Exposure to ether vapor for 1 min twice a day was used as a stressor. Repetitive stress enhanced the number of circulating parasites and cardiac tissue disorganization, from a moderate to a severe diffuse mononuclear inflammatory process and the presence of amastigote burden in the cardiac fibers. Immunological parameters revealed that repetitive stress triggered a reduced concanavalin A induced splenocyte proliferation in vitro with major effects on the late chronic phase. Serum interleukin-12 concentration decreased in both stressed and infected rats in the early phase of infection although it was higher on 180 days post-infection. These results suggest that repetitive stress can markedly impair the host's immune system and enhance the pathological process during the chronic phase of Chagas' disease.     

Customer Satisfaction and Switching Barriers: Effects on Repurchase Intentions,Positive Recommendations,and Price Tolerance1

The current article attempts to extend previous research by testing the effects of customer satisfaction and 2 types of switching barriers—negative and positive—on key manifestations of attitudinal loyalty (repurchase intentions, positive recommendations, and price tolerance). The work also studies whether the effect of customer satisfaction is linear or nonlinear. Finally, the paper analyzes whether switching barriers moderate the relative strength of the customer satisfaction/attitudinal loyalty relation. To this end, a total of 554 private mobile‐phone customers were surveyed. The distinction between negative and positive switching barriers is important to draw theoretical and managerial implications.     

Efficient personality questionnaire for professional training

This study falls within the theoretical framework of the construct of the Efficient Personality. In this work, we present the study of validity and reliability of an original questionnaire made up of 60 items, applied to students from formative cycles of higher Professional Training. The questionnaire was reduced to 24 items, surpassing its initial .84 Cronbach alpha coefficient. Six first-order factors were obtained: Social Self-concept, Academic Self-concept, Solving Ability, Self-esteem, and Problem Coping. One second-order factor was obtained: Efficient Personality. The six-component factorial solution is similar both to the Spanish version for secondary school and to the Chilean versions for secondary and university populations, dividing the initial dimension of Self-concept into Self-concept and Self-esteem.
