A microcomputer system for controlling classical conditioning experiments

A microcomputer-based laboratory system for controlling stimulus presentations and data acquisition in classical conditioning experiments is described. The system comprises an Intel 386/486-based microcomputer and a commercially obtained low-cost counter/timer board with input/output lines for stimulus timing and external device control. A simple, yet versatile custom-designed structured programming language is provided for performing an unlimited number of stimulus configurations and their sequences. In electrophysiological studies, the system can be flexibly connected to computer-controlled signal conditioning systems for the amplification and filtering of multiunit and evoked field potential responses and to high-speed data acquisition systems for sampling and analyzing the responses. The costs of reserving an entire microcomputer for experiment control are well compensated for by the simplicity and efficiency of programming and transportability of the control protocols between different setups and laboratories. Furthermore, a data acquisition and analysis system most suitable for the aims of a research project can be selected.     

Personality,situation, and positive–negative asymmetry in socially desirable responding

Based on previous research on socially desirable responding and positive—negative asymmetry, we hypothesized that (i) impression management is higher in public than in private settings, (ii) personal ideals linked to exemplification, ingratiation, and intimidation are related to an impression management tendency, (iii) negatively keyed social desirability items receive more extreme responses than positively keyed items, and (iv) self-esteem is correlated higher with negatively than with positively keyed self-deception items. Based on Jones and Pittman's (1982) model, exemplification, ingratiation, and intimidation are defined as impression management strategies that aim at presenting oneself as worthy, likable, or dangerous, respectively. Principally, the results obtained in a public setting (N=177) and a private setting (N= 165) support these hypotheses. The overall pattern of findings suggests that both context and personal ideals exert an influence on impression management scores, and that the keying direction of an item may be an important psychological determinant of a test response.     

European norms and equations for a two dimensional presentation of values as measured with Schwartz's 21‐item portrait values questionnaire

The present study utilizes European Social Survey (ESS) data to introduce European norms and equations for computation of the Self‐Transcendence—Self‐Enhancement and Conservation—Openness to Change value dimensions, as measured with the 21‐item Portrait Values Questionnaire (PVQ). Our analysis of ESS round 1 and 2 data suggest that the two‐dimensional structure and the equations based on this structure are extremely robust. Presenting the two value dimensions besides the 10 basic values offers the advantages of (a) heightened reliability, (b) control of response tendency, and (c) possibility to present results in two‐dimensional space.

Self‐esteem and values

The purpose of the present study was to connect personal values to self‐esteem in 14 samples (N = 3612) of pre‐professionals, high school students, and adults, from Finland, Russia, Switzerland, Italy, and Estonia. Self‐enhancement values (power, achievement) and openness to change values (self‐direction, stimulation) were positively, and self‐transcendence values (universalism, benevolence) and conservation values (tradition) were negatively related to self‐esteem. These direct relations between values and self‐esteem were only partly consistent with predictions derived from Maslow's theory of growth and deficiency needs. In samples of pre‐professionals, self‐esteem was correlated with congruence between personal values and the prevailing values environment. On the group‐level, endorsement of achievement and universalism values was more strongly and positively related to self‐esteem in samples where these values were considered more important. In contrast, endorsement of self‐direction and hedonism values was more strongly and positively related to self‐esteem in samples where these values were considered less important. These group‐level results are interpreted as suggesting that attainment of culturally significant goals may raise self‐esteem, but that high self‐esteem may be required for the pursuit of less socially desirable goals.

Personality characteristics of research volunteers

We evaluated Big Five personality factor differences between research volunteers and nonvolunteers. In the first study, 158 military officers were asked to participate in a mail survey. The personality scores of the officers were available from an archival data set. In our second study, adult siblings from large families were invited to participate in extensive clinical epidemiological evaluations. The personality scores of volunteers (N = 55) and nonvolunteers from the same families (N = 29) were estimated from sibling ratings made by those who participated in the study. In both studies, respondents, compared to nonrespondents, were found to be significantly lower in Neuroticism and higher in Conscientiousness. The second study further indicated respondents as being higher in Extraversion and Agreeableness. Copyright © 2007 John Wiley & Sons, Ltd.     

Soft Prosody and Embodied Attunement in Therapeutic Interaction: A Multimethod Case Study of a Moment of Change

This study focused on a moment of weeping in one psychotherapy case. The overall aim was to explore the role of “soft prosody” in psychotherapy interaction—that is, the participants’ use of pauses, a lower volume, slower rhythms, and softer intonation than in the surrounding speech. A mixed-method, micro-analytic perspective was applied to investigate (a) social interaction, including its verbal and nonverbal elements; (2) the participants’ bodily responses, including autonomic nervous system (ANS) measurements; and (3) the participants’ thoughts and feelings during the therapy session, as reported in subsequent individual interviews. Soft prosody was observed to be an important conversational tool. It was used in conveying affiliation and offering therapeutic formulations, and it appeared to contribute both to emotional attunement between the participants and to the therapeutic change that occurred during the interaction under study. Two differing bodily synchronization tendencies in the arousal levels were observed among the participants: (a) a complementary tendency—that is, when the client's arousal increased, the therapist's decreased (occurring during the active therapeutic processing); and (b) a tendency to concurrent decreased arousal in all of the participants.     

Femininity and fertility in sisters with twin brothers: prenatal androgenization? Cross-sex socialization?

Are sisters of twin brothers behaviorally or physiologically masculinized? Prenatal exposure to their brothers' androgens and postnatal socialization experiences unique to girls growing up with twin brothers might influence their attitudes, pubertal development, and reproductive histories. To investigate, we studied age- and cohort-matched samples of Finnish sisters from same-sex and opposite-sex twin pairs. Using data from two ongoing longitudinal studies of consecutive birth cohorts of Finnish twins, we assessed pubertal development at ages 11 and 14 and endorsement of attitudes associated with femininity at age 16. We also studied fertility in Finnish women from same- and opposite-sex twin pairs born from 1958 through 1971, obtaining information on their child-bearing histories when they were ages 15 to 28. Results of each comparison were unambiguously negative: There was no evidence of differences between sisters from same- and opposite-sex twin pairs, and thus, no evidence of either androgenization or cross-sex socialization.     

Personal values and political activism: A cross‐national study

Using data from 28 countries in four continents, the present research addresses the question of how basic values may account for political activism. Study (N = 35,116) analyses data from representative samples in 20 countries that responded to the 21‐item version of the Portrait Values Questionnaire (PVQ‐21) in the European Social Survey. Study (N = 7,773) analyses data from adult samples in six of the same countries (Finland, Germany, Greece, Israel, Poland, and United Kingdom) and eight other countries (Australia, Brazil, Chile, Italy, Slovakia, Turkey, Ukraine, and United States) that completed the full 40‐item PVQ. Across both studies, political activism relates positively to self‐transcendence and openness to change values, especially to universalism and autonomy of thought, a subtype of self‐direction. Political activism relates negatively to conservation values, especially to conformity and personal security. National differences in the strength of the associations between individual values and political activism are linked to level of democratization.
