Contingency learning and stereotype formation: Illusory and spurious correlations revisited

The ability of implicit measures to predict behaviour varies greatly across studies, emphasising the need for accounts of this variability. In order to organise and review the literature on moderators that influence individuals' information processing, we suggest a classification system of moderators with two dimensions. One dimension distinguishes moderators according to their influence on the opportunity to control, the motivation to control, or the reliance on either automatic or controlled processes without changes in opportunity or motivation. The second dimension classifies moderators according to whether they pertain to a disposition of the acting person, the situation in which the behaviour occurs, or the behaviour itself. Increased predictive validity of implicit measures is associated with conditions that foster the impact of automatic processes on behaviour determination. In the discussion we derive several additional moderators from the classification system, delineate emerging research questions, and discuss implications of the reviewed studies for research on self-regulation.     

Demand Characteristics and Self-Report Measures of Imaginary Audience Sensitivity: Implications for Interpreting Age Differences in Adolescent Egocentrism

Self-consciousness during early adolescence has been explained as an outcome of adolescent egocentrism, in which adolescents create an imaginary audience (IA) of attentive, critical peers. The possibility that such self-consciousness might result from contact with peers who are more attentive and critical than those encountered during childhood or adulthood has not been considered. Study I tested whether young adults, who are not theoretically susceptible to IA, could be made to receive high scores on IA and self-consciousness measures by having them complete a procedure in 1 of 3 laboratory conditions—a critical audience, a noncritical audience, or no audience. However, participants in the critical-audience condition received significantly lower IA and self-consciousness scores than participants in the no-audience condition did. Study 2 tested whether the directions given to Study I participants might have been responsible for the unexpected findings. Results indicated that participants instructed to give mature-sounding responses received lower IA/self-consciousness scores than did those asked to report their honest opinions. Together, the results of Studies 1 and 2 indicated that survey measures of IA are subject to demand characteristics and highlighted the need to interpret with caution age differences in IA as traditionally assessed.     

What COP and Kinematic Parameters Better Characterize Postural Control in Standing Balance Tasks?

The authors’ aim was to determine which variables allow for the characterization of motor balance behavior. Traditional measures and nonlinear measures of center of pressure (COP; n = 30) and kinematics (n = 10) were tested in their absolute and relative consistency in a 30-s standing balance task protocol under stable and unstable conditions. Regarding COP variables, mean velocity (mVel), permutation entropy (PE) and detrended fluctuation analysis (DFA) exhibited high consistency between trials and ranked individuals more accurately compare with other metrics. In the kinematic signal mVel, PE and DFA had good intrasession reliability values in unstable conditions. Overall, the intrasession reliability values were better in the unstable condition than in the stable condition and the measures calculated using derived data had better intrasession reliability values. In conclusion, mVel, PE, and DFA allow for the good characterization of motor balance behavior in a simplified protocol where velocity time series are analyzed.     

The 24-item Brief HEXACO Inventory (BHI)

Up until now, no really short instrument that measures the six personality dimensions of the HEXACO model has been available. In two studies, I report the construction of the Brief HEXACO Inventory (BHI), which represents the 24 HEXACO facets with 1 item per facet (i.e., 4 items per domain) and which takes approximately 2–3 min to complete. Although characterized by relatively low alpha reliability, its test–retest stability, self-other agreement, and convergent correlations with full-length scales are relatively high and its validity loss is only modest. Correcting for attenuation using a weighted average of alpha reliability, test–retest stability, and self-other agreement, the BHI re-estimates the original construct validity correlations of the HEXACO-PI-R with relatively great accuracy.     

Measuring Fear of Movement/(Re)injury in Chronic Low Back Pain Using Implicit Measures

Fear of movement/(re)injury is assumed to contribute to the development and maintenance of chronic low back pain (CLBP) in a subgroup of patients. Studying fear of movement/(re)injury with implicit attitude measures, without the awareness of the patient, might be a valuable addition to self‐report questionnaires. The aims of the current study were to investigate whether CLBP patients demonstrate more implicit fear of movement/(re)injury than healthy controls, and whether 2 implicit measures are related to each other, and to an explicit self‐report measure of fear of movement/(re)injury. A group of 66 CLBP patients and 30 healthy controls took part in this study. In addition to self‐report questionnaires, fear of movement/(re)injury was implicitly assessed by the Extrinsic Affective Simon Task (EAST) and the Go‐No‐Go‐Association Task (GNAT) that aimed to determine the association between back‐stressing movements and the evaluation “threatening”. On both implicit tasks it was found that neither CLBP patients nor healthy controls demonstrated implicit fear of movement/(re)injury, and that CLBP patients did not differ from healthy controls in their level of implicit fear of movement/(re)injury. In general, no associations were found between the EAST and the GNAT, or between implicitly measured and self‐reported fear of movement/(re)injury. One major caveat in drawing inferences from these findings is the poor reliability of these implicit measures. Research towards the psychometric properties of these measures should first be expanded before modifying, and applying, them to more complex domains such as fear of movement/(re)injury.     

Effects of low survivability cues and participant sex on physiological and behavioral responses to sexual stimuli

According to life history theory, environmental cues indicating that one's future survivability is low increase reproductive effort. This suggests that exposure to low survivability cues will increase people's preparedness to engage in sex. However, according to sexual selection theory and parental investment theory, evolutionary pressures favored a more conservative sexual strategy among women compared to men. We therefore hypothesized that men, but not women, would respond to low survivability cues with increased sexual preparedness. Accordingly, both subliminal and supraliminal death primes (as compared with control primes) led men, but not women, to exhibit increased physiological arousal in response to sexual images (Study 1), and stronger approach-oriented behavioral responses to sexual images (Study 2). Theoretical implications for life history theory are discussed.     

Information‐Theoretic Measures Predict the Human Judgment of Rhythm Complexity

To formalize the human judgment of rhythm complexity, we used five measures from information theory and algorithmic complexity to measure the complexity of 48 artificially generated rhythmic sequences. We compared these measurements to human prediction accuracy and easiness judgments obtained from a listening experiment, in which 32 participants guessed the last beat of each sequence. We also investigated the modulating effects of musical expertise and general pattern identification ability. Entropy rate and Kolmogorov complexity were correlated with prediction accuracy, and highly correlated with easiness judgments. A logistic regression showed main effects of musical training, entropy rate, and Kolmogorov complexity, and an interaction between musical training and both entropy rate and Kolmogorov complexity. These results indicate that information‐theoretic concepts capture some salient features of the human judgment of rhythm complexity, and they confirm the influence of musical expertise on complexity judgments.     

Construct Validity of the Balloon Analogue Risk Task (BART): Relationship with MDMA Use by Inner-City Drug Users in Residential Treatment

In a program of research assessing the validity of the balloon analogue risk task (BART; C. W. Lejuez et al., 2002) as a measure of risk taking, the BART was administered to a sample of inner-city drug users in residential treatment (n = 76). Construct validity of the BART was evaluated by measuring risk-taking behavior and 3,4-methylenedioxymethamphetamine (MDMA) use while controlling for self-reported impulsivity, sensation seeking, polysubstance use, and demographic variables. Supporting the construct validity of the BART, while controlling for interrelated variables in the context of logistic regression analyses, (BART) risk-taking propensity accounted for significant incremental variance in differentiating MDMA users from non-users. BART scores, polysubstance use, and younger age were most associated with MDMA use, and together these variables were associated with 91% classification accuracy in predicting MDMA use.     

Memory-based versus on-line processing: Implications for attitude strength

Three experiments tested whether the manner in which attitudes are created—through on-line or memory-based processing—can impact the resultant strength of those attitudes. In each study, participants were presented with 20 behavioral statements about a person named Marie. Whereas some participants were asked to continually evaluate Marie based upon each sentence and then report their overall evaluation (on-line processing), others were asked to focus on the sentence structure and to evaluate Marie only after they had read all the sentences (memory-based processing). Even when controlling for attitude accessibility, attitudes created through on-line processing were stronger than attitudes created through memory-based processing: Experiment 1 showed that participants in the on-line condition felt more certain of their attitudes, Experiment 2 showed that on-line attitudes were better predictors of participants’ evaluative preferences, while Experiment 3 showed that on-line attitudes manifested stronger attitude-behavioral intention correspondence.
