A portable version of the go/no-go association task (GNAT).

The present article describes a portable version of the go/no-go association task (GNAT) that runs on Palm Pilot and Handspring personal digital assistant (PDA) devices. The PDA version of the GNAT was modeled after a portable version of the Implicit Association Test (Dabbs, Bassett, & Dyomina, 2003) and was designed to facilitate measurement of implicit social cognition in field settings and among difficult-to-reach populations. The PDA version of the GNAT was used to assess implicit attitudes about smoking among 11 smokers and 28 nonsmokers. Support for the validity of the PDA version of the GNAT was provided by findings that smokers showed less negative implicit attitudes toward smoking, as measured by the GNAT, than did nonsmokers and that these implicit attitudes were positively correlated with self-reported smoking attitudes among both groups.

Testosterone as a social inhibitor: two case studies of the effect of testosterone treatment on language.

This study aimed to correlate testosterone levels with natural written language in 2 people undergoing testosterone therapy. Two participants, a man receiving treatment for loss of upper-body strength and a female-to-male transgendered individual, supplied records of injections over 1-2 years along with e-mails or journal entries as writing samples. Results showed that higher testosterone levels correlated with reduced use of words related to social connections. Language relating to anger, sexuality, and achievement was unrelated to testosterone levels. It appears that testosterone steers attention away from social connections but not necessarily toward concerns with aggression or sexual activity.

The palm IAT: a portable version of the implicit association task.

The Implicit Association Test (IAT) uses reaction times to measure implicit linkages among concepts or between concepts and attributes. The Palm IAT is a simplified version of the IAT that runs on Palm Pilot or Handspring Visor personal digital assistant devices. The Palm IAT is portable, provides precise measurement, and allows for efficient data collection inside or outside the laboratory. Three studies were conducted to asses its practical usefulness. Study 1 (N = 1 2) replicated a previous demonstration of more favorable implicit associations for flowers than for insects. Study 2 (N = 9) found individual differences in linking the self-concept to characteristics of agency and communion. Study 3 (N = 23) found individual differences in linking the self-concept to characteristics of boldness and friendliness. Reliability of the Palm IAT is similar to reliability of theoriginal desktop computer version. Using the Palm IAT, one can study hard-to-reach populations in unusual settings.

Testosterone, alcohol, and civil and rough conflict resolution strategies in lesbian couples.

The present study investigated the relations among testosterone level, acute alcohol consumption, and the use of violent (Rough) or non-violent (Civil) conflict resolution strategies in lesbian couples. The participants were 54 lesbian campers at a women's campground or spectators at a gay pride celebration who each provided a saliva sample for testosterone assay and completed a questionnaire. On the questionnaire, participants indicated whether they used Civil or Rough tactics to deal with domestic discord, and whether or not their use of these tactics varied with their use of alcohol. High testosterone women used Rough tactics equally when drinking as when not drinking, while low testosterone women used Rough tactics far more often when drinking than when not drinking. Alcohol appears to release violent tenden- cies in low testosterone women, who are characteristically restrained under sober conditions, but has little effect on high testosterone women.

Testosterone and occupational choice: actors, ministers, and other men.

Occupational differences in testosterone concentrations, focusing on actors and ministers, were explored in 3 studies. The 1st examined salivary testosterone in 7 occupational groups and an unemployed comparison group and found actors and football players higher than ministers but no other significant differences. The 2nd examined salivary testosterone in 2 kinds of actors (stage actors and comedians) and 2 kinds of ministers (pastoral ministers and missionaries) and found actors high and ministers low but no differences between subgroups within each occupation. The 3rd examined serum testosterone in entertainers and ministers in an archival sample of military veterans and found entertainers high and ministers low. The results are interpreted in terms of dominance and antisocial tendencies, with the conclusion that these variables are complex and can affect occupational preference in subtle ways.
