Decomposing retrieval and integration in memory for actions: a multinomial modeling approach.

Typically, action phrases are recalled better if participants are asked to enact the phrases than if they are just asked to remember them. When investigating which processes constitute this enactment effect a difficulty is that observable effects in standard memory tests are ambiguous because such tests require several processes. In the present article, we introduce a multinomial model that decomposes observable memory performance into a retrieval parameter and a parameter concerning the item-specific processing and integration of an action phrase. These parameters are estimated from free recall and cued recall performance. The model fitted the data of two experiments designed to test it. Experiment 1 demonstrated the basic usefulness of the model by showing expected differences in the integration parameter in the absence of unexpected differences in the retrieval parameter. Experiment 2 extended the conditions under which the model is useful by showing expected differences in the retrieval parameter even in the presence of unexpected differences in the integration parameter. Together, these findings support our theoretical framework according to which enactment generally boosts integration of action phrases, but increases retrieval only for phrases with context cues.

Implicit and explicit attitudes towards lesbians and gay men.

Attitudes towards lesbians and gay men, as assessed with questionnaires, have become more and more positive in the last decades. An open question is, however, whether that trend reflects true change or rather a growing reluctance to admit negative attitudes (to others and self). New procedures measuring implicit attitudes may help find an answer. In three studies with 208 students at a German university, attitudes towards lesbians and gay men were measured with explicit scales and with an Implicit Association Test (Greenwald, McGhee, & Schwartz, 1998) adapted for that purpose. Explicit attitudes were very positive. However, implicit attitudes were relatively negative instead, except for female participants' implicit attitudes towards lesbians which were repeatedly as positive as were their attitudes towards heterosexuals. The internal consistencies of the implicit tests were exemplary. Correlations with sexual orientation as well as with explicit homosexuality-related and gender-related attitudes attested to their validity. However, context effects were found for different implicit attitudes measured in close succession, and correlations of implicit homosexuality-related and gender-related attitudes could not be detected.

Gender bias in fame judgments: implicit gender stereotyping or matching study phase fame?

Familiarized names are falsely judged famous more often than nonfamiliarized names. Banaji and Greenwald (1995) demonstrated a gender bias in this false fame effect, with the effect being larger for male than for female names. This effect was interpreted as reflecting the operation of a gender stereotype. However, the famous male names were, in fact, better known than the famous female names. Thus, the presence of more famous male names during study may have contributed to the observed male-famous association. If so, there should be no gender bias if the studied famous male and female names are equally famous, and a reversed gender bias should emerge if the famous female names are more famous than the male names. In two experiments, these predictions were corroborated. A "classical" gender bias was found only when the famous males were more famous than the famous females. These findings are consistent with the hypothesis that the gender bias in fame judgments, rather than showing implicit gender stereotyping in the sense of a transsituational judgment bias, reflects the fact that, in test, participants select a proportion of fame judgments to male and female names so that it matches the relative degree of fame of male and female names encountered during study.

Is the implicit association test immune to faking?

One of the main advantages of measures of automatic cognition is supposed to be that they are less susceptible to faking than explicit tests. It is an empirical question, however, to what degree these measures can be faked, and the response might well differ for different measures. We tested whether the Implicit Association Test (IAT, Greenwald, McGhee, & Schwartz, 1998) cannot be faked as easily as explicit measures of the same constructs. We chose the Big-Five dimensions conscientiousness and extraversion as the constructs of interest. The results show, indeed, that the IAT is much less susceptible to faking than questionnaire measures are, even if no selective faking of single dimensions of the questionnaire occurred. However, given limited experience, scores on the IAT, too, are susceptible to faking.

Attitudes toward lesbians, gay men, bisexual women, and bisexual men in Germany.

Attitudes toward lesbians, gay men, bisexual women, and bisexual men were assessed in a national representative sample of 2,006 self-identified heterosexual women and men living in Germany. Replicating previous findings, younger people held more favorable attitudes than older people; women held more favorable attitudes than men; and men held more favorable attitudes toward female than male homosexuality, whereas women did not differentiate. However, women held more favorable attitudes toward homosexuals than toward bisexuals, whereas men did not differentiate. Knowing a homosexual person was an important predictor of attitudes, as was political party preference. Both same-sex and opposite-sex sexual attraction were substantially related with attitudes. Our findings support the notion that attitudes toward lesbians, gay men, bisexual women, and bisexual men are related but distinct constructs.

Implicit Association Test: separating transsituationally stable and variable components of attitudes toward gay men.

Implicit attitudes are conceived of as formed in childhood, suggesting extreme stability. At the same time, it has been shown that implicit attitudes are influenced by situational factors, suggesting variability by the moment. In the present article, using structural equation modeling, we decomposed implicit attitudes towards gay men into a person factor and a situational factor. The Implicit Association Test (Greenwald, McGhee, & Schwartz, 1998), introduced as an instrument with which individual differences in implicit attitudes can be measured, was used. Measurement was repeated after one week (Experiment 1) or immediately (Experiment 2). Explicit attitudes towards gay men as assessed by way of questionnaires were positive and stable across situations. Implicit attitudes were relatively negative instead. Internal consistency of the implicit attitude assessment was exemplary. However, the within-situation consistency was accompanied by considerable unexplained between-situation variability. Consequently, it may not be adequate to interpret an individual implicit attitude measured at a given point in time as a person-related, trait-like factor.
