Resources at the HuMAN Lab
The HuMAN Lab is equipped
for the assessment of hormonal and immunological parameters. It
is licensed for use of radioisotopes (iodine 125) to perform radioimmunoassays.
We can also perform enzymatic immunoassays. In the past, we have
developed and used protocols to assess testosterone, cortisol,
estrogen, and progesterone in saliva (e.g., Campbell, Schultheiss,
& McClleland, 1999; Schultheiss, Dargel, & Rohde, 2003
The HuMAN Lab is also equipped with 13 workstations
for the computer-based assessment of motives (e.g., a computerized
PSE), cognitive functions, and behavior (e.g., allocation of attention,
brain laterality, implicit sequence learning, referential processing).
On up to 4 of these workstations simultaneously, physiological
parameters such as heart rate, skin conductance, facial EMG, and
startle reflex potentiation can be measured.
All data collection procedures, instructions, tasks,
and questionnaires are programmed with experimental software, such as Inquisit,
MediaLab, and DirectRT. Sequential presentation of task and instruction modules
is automatized through batch files. This ensures an extremely high level
of standardization of data collection procedures, exact control over what
type of stimuli participants are exposed to and for how long, eliminates
the need for manual data entry and text transcription, and minimizes experimenter
effects on research participants, which, given implicit motives' sensitivity
to nonverbal cues, can be sizeable.
