PHYSIOLOGICAL AND IMPLICIT MEASURES

Specific physio measuresand examples

Electromyography (facial emotion) Measures of arousal

Galvanic skin response Pupillary response Cardiac response, blood pressure, blood

volume (also, mental workload, challenge vs. threat)

Respiration What are the problems with using general

measures of arousal?

More complicated measures

Electrooculography Electrical potentials in the brain fMRI

Physio measures

What are their advantages and disadvantages?

Vul, Harris, Winkielman, & Pasher, 2009

Presentations

Hormone sampling Eye tracking—Lee EKG/ERP fMRI--Manny

Implicit measures

What is an implicit measure? “outcome of a measurement procedure that is

causally produced by psychological attributes in an automatic manner” (p. 177, DeHouwer & Moors, 2010)

Is it conscious? Is it automatic? How do we know if something is

conscious or automatic?

Examples of implicit measures

How might these be used in studies? Supraliminal priming Subliminal priming IAT Word completion Story completion Nonverbals Type of language used (concrete vs. not) GNAT Physiological measures Projective tests Name preference test Affect misattribution procedure

De Houwer and colleagues’ criteria

Three normative internal criteria (De Houwer et al., 2009—see Table 10.1) Clear what it measures Clear how it works (what diffs. in measure mean) Clear that automatic processes

External criteria Self-assessment Behavioral vs. physiological vs. neurological

responses Symbolic vs. nonsymbolic Stimulus-response compatibility

Implicit measures

How do these measures relate to each other?

To explicit attitudes? To behaviors? Do we have 2 attitudes for everything? What are the advantages and

disadvantages of these types of measures?

IAT

What is it? How does it work? What is it measuring? What does it predict? How has validity for the IAT been shown? What are some problems in interpreting

IAT scores? How does the IAT work? (process) Is it implicit? Should we use it?

Affective priming

How has validity been shown? How does affective priming work?

(process) Is it implicit? Should we use it? Recent priming crisis

Implications of De Houwer et al.

For developing measures For using measures For testing reliability and validity
