The interaction between response effects during the acquisition of response priming

In three experiments we investigated the role of associative learning in the acquisition of response priming by effect stimuli, by examining their interaction during response-effect learning. Having replicated the ability of visual effect stimuli to prime their associated responses, we paired a response with a compound consisting of visual and auditory effects before assessing the ability of the auditory effect stimulus to prime the response. This priming was reduced if the visual stimulus had been pre-trained as an effect of the response. By contrast, priming by the visual effect stimulus was potentiated when the auditory effect had been pre-trained. We interpret these interactions in terms of contemporary associative learning theory derived from studies of conditioning.     

Bullying in elementary school, high school, and college

This study investigated the continuity in being a bully, victim, or bully-victim from elementary school through college in 119 undergraduates. Of 25 who bullied in college, 18 (72%) had been bullied in high school and elementary school. Of 26 bullies in college, 14 (53.8%) had been bullies in high school and elementary school. Of 12 bully-victims in college, 5 (41.6%) had been bully-victims in high school and elementary school. There were significant positive correlations between being a bully in college, high school, and elementary school, and being bullied in college and high school, and high school and elementary school, and between being both a bully and victim in elementary school, a bully and victim in high school, and a bully and victim in college.     

An examination of self-presentational concern of Turkish adolescents: an example of physical education setting

The purpose of this study was to examine self-presentational concern of Turkish adolescents with regard to the gender composition of physical education (PE) class and also to investigate the attitude toward PE and PE class preferences of Turkish adolescents based on this concern. A total of 1,807 eighth-grade students (936 females and 871 males) completed the Attitudes Toward Physical Education Scale and Social Physique Anxiety Scale (SPAS). The findings indicated that although self-presentational concern did not differ according to the gender composition of PE class, there was a significant difference in class preference among adolescents based on this concern with most of the females who had a high self-presentational concern preferring noncoed PE class. Additionally, no significant difference was found in attitude toward PE among self-presentational concern groups. These findings are discussed in relation to the sex composition of PE class and self-presentational concerns of adolescents.     

Reanalysis of the Grønnerød (2003) Rorschach temporal stability meta-analysis data set

I reanalyzed the Gr?nner?d (2003) Rorschach temporal stability meta-analysis data with a theoretically driven hierarchical regression analysis. I also examined the intrarater reliability of initial coding decisions and verified their consistency. In the new regression analyses, retest period strengthened its influence on stability, whereas methodological factors showed a tendency toward influence. The new results are more in line with the results from Gr?nner?d's (2004) psychotherapy change meta-analysis results.     

Psychopathic and nonpsychopathic violent offenders on the rorschach: discriminative features and comparisons with schizophrenic inpatient and university student samples

We examined discriminant and convergent validity of theoretically relevant Rorschach Comprehensive System (CS) variables (Exner, 2003) and Meloy and Gacono's (1992) aggression variables in distinguishing between imprisoned violent offenders (VO) who were psychopathic (P-VO) and nonpsychopathic (NP-VO) under psychiatric treatment, schizophrenic inpatients (ISs), and university students (USs). A total of 7 of 12 variables discriminated significantly between P-VO and NP-VO, which suggests more aggressive, cognitive, and interpersonal disturbances among P-VO. We also found significant differences between VOs, ISs, and USs. Logistic regression analyses revealed that AgPast accumulated incrementally in the classification of P-VO versus NP-VO, and AgC accumulated incrementally in the classification of VO versus IS when entered after CS variables. The findings support the view that psychopathy is a distinctive form of antisocial personality disorder (Diagnostic and Statistical Manual of Mental Disorders; American Psychiatric Association, 1994) organized at a more severe pathological level.     

Validation of a shortened assessment of physical self in adults

The purpose was to adapt a brief tool, the Physical Self Inventory-Version b, for the assessment of physical self in adults. The inventory is a refined version of the previously validated version, which was derived from the Physical Self Inventory (25 items). This French validation of the Physical Self-Perception Profile of Fox and Corbin includes a global self-esteem scale. As in the earlier version the current one has 6 single items to assess dimensions of global self-esteem, physical selfworth, sport competence, physical condition, attractive body, and physical strength. Rating is performed on a visual analog scale. Items in the new inventory were stated in the first person and in more general terms to be acceptable to a wider range of subjects. An item of measurement error was added. Analysis of responses of 185 men and 148 women to the new version supported the hierarchical structure. Significant correlations between the scores and constructs like masculinity, neuroticism, and depression indicated external validity. The new inventory showed acceptable psychometric properties for use in idiographic studies.     

The plural self and a Taoist orientation in two cultures

A positive association between having a Taoist orientation to life and unity in the subjective perception of the self was found in samples of both American (n = 99) and Turkish (n = 100) respondents.

Can humans perceive their brain states?

Although the brain enables us to perceive the external world and our body, it remains unknown whether brain processes themselves can be perceived. Brain tissue does not have receptors for its own activity. However, the ability of humans to acquire self-control of brain processes indicates that the perception of these processes may also be achieved by learning. In this study patients learned to control low-frequency components of their EEG: the so-called slow cortical potentials (SCPs). In particular "probe" sessions, the patients estimated the quality of the SCP shift they had produced in the preceding trial. The correspondence between the recorded SCP amplitudes and the subjective estimates increased with training. The ability to perceive the SCPs was related to the ability to control them; this perception was not mediated by peripheral variables such as changes in muscle tonus and cannot be reduced to simple vigilance monitoring. These data provide evidence that humans can learn to perceive the neural activity of their brain. Alternative interpretations are discussed.
