The Hormonal Correlates of Implicit Motives

Implicit motives represent nonconsciously represented dispositions to seek specific classes of incentives and to avoid corresponding classes of disincentives. Growing evidence suggests that the implicit power motive is associated with basal levels and reactivity of the gonadal steroid hormones testosterone in men and estradiol in women. It is also associated with increased release of stress hormones (cortisol, norepinephrine) in response to dominance challenges and social defeat. The implicit affiliation motive is linked to the release of progesterone: increases in progesterone are followed by increases in affiliation motivation, and arousal of affiliation motivation is associated with concurrent or subsequent progesterone increases. There is limited evidence for a role of vasopressin in achievement motivation. These findings point to a key role of the hypothalamus for implicit motives, a role that is consistent with the existence of function‐specific nuclei within this brain area.     

Serum cortisol,testosterone, and testosterone-binding globulin responses to competitive fighting in human males

Levels of circulating cortisol, testosterone, and testosterone-binding globulin were measured in 15 male wrestlers in relation to wrestling bouts and their outcomes. Concentrations of cortisol and testosterone increased consistently during wrestling bouts, while levels of testosterone-binding globulin dropped. Winners of competive matches showed greater increases in both cortisol and testosterone than losers. These findings indicate that humans, like other social mammals, may undergo specific endocrine changes in response to victory or defeat.     

Smoking in movies, implicit associations of smoking with the self, and intentions to smoke

We examined whether identifying with a film character who smokes increases implicit associations of the self with smoking. Undergraduate men were randomly assigned to view film clips in which the male protagonist either smoked or did not smoke. We measured subsequent levels of self-smoking associations using a reaction time task, as well as self-reported beliefs about smoking and smokers. Greater identification with the smoking protagonist predicted stronger implicit associations between the self and smoking (for both smokers and nonsmokers) and increased intention to smoke (among the smokers). Stronger implicit self-smoking associations uniquely predicted increases in smokers' intentions to smoke, over and above the effects of explicit beliefs about smoking. The results provide evidence that exposure to smoking in movies is causally related to changes in smoking-related thoughts, that identification with protagonists is an important feature of narrative influence, and that implicit measures may be useful in predicting deliberative behavior.     

The social endocrinology of dominance: basal testosterone predicts cortisol changes and behavior following victory and defeat

Past research suggests that individuals high in basal testosterone are motivated to gain high status. The present research extends previous work by examining endocrinological and behavioral consequences of high and low status as a function of basal testosterone. The outcome of a competition--victory versus defeat--was used as a marker of status. In Study 1, high testosterone men who lost in a dog agility competition rose in cortisol, whereas high testosterone men who won dropped in cortisol. Low testosterone men's cortisol changes did not depend on whether they had won or lost. Study 2 replicated this pattern of cortisol changes in women who participated in an experimental laboratory competition, and Study 2 extended the cortisol findings to behavior. Specifically, high testosterone winners chose to repeat the competitive task, whereas high testosterone losers chose to avoid it. In contrast, low testosterone winners and losers did not differ in their task preferences. These results provide novel evidence in humans that basal testosterone predicts cortisol reactivity and behavior following changes in social status. Implications for the social endocrinology of dominance are discussed.     

Anxiety,hormonal responses,and coping during a judo competition

Competitive situations induced hormonal changes, depending on the outcome, victory or defeat. This study aimed to investigate the salivary testosterone (T) and cortisol (C) and the mental state responses to a real judo championship. Data about individuals’ anxiety levels, strategies of coping, and patterns of behavior were thus collected. The relationship between hormonal changes and psychological variables were also analyzed. Our results showed a C response to competition, which was especially characterized by an anticipatory rise. Depending on outcome, results did not show statistically significant different C responses. The T values noted after the last fight were significantly greater in the losers than those obtained in the winners. Hormonal response did not show a relationship with psychological variables depending on the outcome. Losers showed just before the first fight an elevated cognitive anxiety, accompanied by low self‐confidence. Moreover, they were characterized by type B behavior. Types of coping strategies also differentiated losers from winners. Finally, even if no relationships between hormonal and psychological variables depending on the outcome were found, our results showed that state and trait psychological variables, as well as the coping strategies, must be taken into account to better understand the response to competitive situations.

Explicit and implicit approach motivation interact to predict interpersonal arrogance

Self-reports of approach motivation are unlikely to be sufficient in understanding the extent to which the individual reacts to appetitive cues in an approach-related manner. A novel implicit probe of approach tendencies was thus developed, one that assessed the extent to which positive affective (versus neutral) stimuli primed larger size estimates, as larger perceptual sizes co-occur with locomotion toward objects in the environment. In two studies (total N = 150), self-reports of approach motivation interacted with this implicit probe of approach motivation to predict individual differences in arrogance, a broad interpersonal dimension previously linked to narcissism, antisocial personality tendencies, and aggression. The results of the two studies were highly parallel in that self-reported levels of approach motivation predicted interpersonal arrogance in the particular context of high, but not low, levels of implicit approach motivation. Implications for understanding approach motivation, implicit probes of it, and problematic approach-related outcomes are discussed.     

Multiple contest experiences interact to influence each other’s effect on subsequent contest decisions in a mangrove killifish

Many animals modify behavioural decisions based on information they have previously acquired. Contest behaviour is often affected by previous contest experiences: individuals behave more and less aggressively after a victory and defeat, respectively (winner/loser effect). Individuals in the field sometimes encounter multiple competitors in quick succession, but whether these experiences interact to influence each other’s importance is unclear. We tested five hypotheses for experience interaction (no interaction, retroactive interference, proactive interaction, reinforcement and diminishing returns) using Kryptolebias marmoratus. Focal individuals were paired up with opponents having the same 1-month contest outcome (1 month before the experiment), as this difference in actual or perceived fighting ability has been shown to affect the fish’s response to new experiences. We gave the focal individual of a pair a winning or losing experience on day 1. Then both fish of the pair received the same winning, losing or no-contest experience on day 2. Then we organised fights between the two. The effect of a day-1 losing experience did depend on the fish’s actual or perceived fighting ability: one-month losers readily showed loser effects from the day-1 losing experience, irrespective of the day-2 experience (i.e. no interaction between day-1 and day-2 experiences). One-month winners, however, only showed loser effects from a day-1 losing experience when the day-2 experience was also a loss (i.e. reinforcement). Day-1 winning experiences did not interact with day-2 experiences in 1-month losers or winners. Therefore, multiple experiences sometimes reinforce each other, but how they combine to influence behaviour depends on an individual’s actual or perceived fighting ability.     

Women in power-themed tasks: Need for power predicts task enjoyment and power stress

The implicit power motive predicts individuals’ involvement in activities that allow them to have impact and influence on other people. Moreover, substantial evidence indicates that thwarting individuals’ implicit power motive relates to so-called power stress. The present series of studies addresses both topics among female participants. In study 1, findings indicate that the strength of the implicit power motive moderates the relationship between women’s self-reported dominance and their evaluations of a power-related task: A significant link between self-reported dominance and both motivation for task participation and task enjoyment could be verified only when the implicit power motive was well-pronounced. In the subsequent studies, actual and anticipated thwarting of the satisfaction of a strong implicit power motive was associated with different psychological and behavioral indicators of power stress. Participants with a high implicit power motive felt more negative affect (study 2), reported more negative explicit (study 3) and implicit (study 4) attitudes towards a dominant target person, and were coded more often for visible frown reactions (study 5) when the satisfaction of their implicit power motive was (potentially) thwarted compared to participants with a low implicit power motive and participants with a high implicit power motive that was, however, not at risk of being thwarted.

     

Social motives and cognitive power-sex associations: predictors of aggressive sexual behavior

The present study investigated whether implicit social motives and cognitive power-sex associations would predict self-reports of aggressive sexual behavior. Participants wrote stories in response to Thematic Apperception Test pictures, which were scored for power and affiliation-intimacy motives. They also completed a lexical-decision priming task that provided an index of the strength of the cognitive association between the concepts of "power" and "sexuality." For men, high levels of power motivation and strong power-sex associations predicted more frequent aggression. There was also an interaction: Power motivation was unrelated to aggression for men with the weakest power-sex associations. For women, high levels of affiliation-intimacy motivation were associated with more frequent aggression. Strong power-sex associations were also predictive for women but only when affiliation-intimacy motivation was high.     

Recovering from negative events by boosting implicit positive affect

Upregulation of implicit positive affect (PA) can act as a mechanism to deal with negative affect. Two studies tracked temporal changes in positive and negative affect (NA) assessed by self-report and the Implicit Positive and Negative Affect Test (IPANAT; Quirin, Kazen, & Kuhl, 2009). Study 1 observed the predicted increases in implicit PA after exposure to a threat-related film clip, which correlated positively with the speed of recognising a happy face among an angry crowd. Study 2 replicated increases in implicit PA after exposition to the same film clip, and showed that such increases were enhanced by priming self-referential stimuli. The findings are discussed against the background of personality systems interaction (PSI) theory (Kuhl, 2000, 2001), which emphasises the role of the implicit self in affect regulation.     

Wishes, Motives, Goals, and Personal Memories: Relations of Measures of Human Motivation

ABSTRACT The purpose of this study was to compare measures of explicit and implicit motives. One hundred and one participants completed six measures of motivation, including Thematic Apperceptive stories, autobiographical memories, three wishes, personal striving lists, the Personality Research Form, and self-ratings. Stories, memories, wishes, and strivings were content-analyzed using Winter's (1989) system. Although overall correlations did emerge among explicit measures within the same motive, there were numerous correlations among methodologically similar measures of different motives. In general, explicit measures did not correlate with thematic measures of the same motives. Although correlations among measures were similar for men and women, explicit measures of power converged with thematic measures of power only for men. Exploratory factor analysis identified three factors: explicit achievement, explicit affiliation, and power. Implicit achievement motivation loaded negatively on the affiliation factor. Implications for research on implicit and self-attributed motivation are discussed.

Implicit motives and sexual conservatism as predictors of sexual behaviors

This study was designed to provide an assessment of the relationship between the two most important implicit motives and the most frequently studied sexual behaviors. A community sample of 102 men and 92 women completed measures of implicit power and affiliation-intimacy motives, sexual conservatism, social desirability, and sexual behavior. For men, high power motivation was positively associated with the number of sexual partners and the frequency of sex. There was an interaction between sexual conservatism and power motivation in women. For women low in sexual conservatism, high power motivation was positively associated with the number of sexual partners and with earlier initiation to intercourse and oral sex. There were few associations between affiliation-intimacy motivation and sexual behaviors; however, women high in this motive reported later initiation to oral sex.     

Romantic jealousy and implicit and explicit self-esteem

Research on romantic jealousy and self-esteem mostly relies on the measurement of explicit (i.e., conscious, deliberate) aspects, without taking recent developments of the measurement of implicit (i.e., automatic) aspects into account. In this study (N = 154), we applied several measures of romantic jealousy and self-esteem (explicit, implicit), finding sex-specific as well as measurement-specific effects. Men (but not women) higher in jealousy had lower explicit self-esteem, whereas women (but not men) higher in jealousy had higher implicit self-esteem, but only when using the Implicit Association Test (whereas not the Initial Preference Task) for measuring implicit self-esteem. Individuals with damaged (i.e., low explicit and high implicit) self-esteem were more jealous than those with fragile (i.e., high explicit and low implicit) self-esteem. This differential effect was due to higher implicit self-esteem among women, whereas lower explicit self-esteem among men. These novel findings not only add to the expanding literature on romantic jealousy research, but also to research on self-esteem discrepancies.     

Age and gender differences in implicit motives

Research on age differences in implicit motives is rare and has shown contradictory results. We investigated age and gender differences in implicit motives (achievement, power, affiliation and intimacy), measured by the Picture Story Exercise (PSE), in an extensive, heterogeneous dyadic sample of 736 adults aged 20–80 years. Data were analyzed with a multilevel approach. Results indicate lower motive scores in all four measured motives in aged as compared to young adults but higher scores in activity inhibition. Further, women scored higher in affiliation and intimacy motives than men, while men scored higher in achievement and power motives and in activity inhibition than women. Possible underlying affective and neuroendocrinological processes of age dependent change in implicit motives are discussed.     

Implicit Motives and Sexual Conservatism as Predictors of Sexual Behaviors

ABSTRACT

This study was designed to provide an assessment of the relationship between the two most important implicit motives and the most frequently studied sexual behaviors. A community sample of 102 men and 92 women completed measures of implicit power and affiliation-intimacy motives, sexual conservatism, social desirability, and sexual behavior. For men, high power motivation was positively associated with the number of sexual partners and the frequency of sex. There was an interaction between sexual conservatism and power motivation in women. For women low in sexual conservatism, high power motivation was positively associated with the number of sexual partners and with earlier initiation to intercourse and oral sex. There were few associations between affiliation-intimacy motivation and sexual behaviors; however, women high in this motive reported later initiation to oral sex.     

An implicit basis for the retention benefits of random practice

The cognitive effort explanations of contextual interference (CI) and implicit motor learning represent a paradox in which cognitive involvement is seen to be advantageous or disadvantageous for learning. The authors aimed to resolve this paradox by measuring cognitive effort and working memory dependence during low and high CI practice on two Australian Rules Football tasks (kicking and handball). Measures of cognitive effort included: kicking and handball outcome performance during acquisition and during a test of retention, performance on a probe reaction time task during a sample of acquisition trials, and self-reported levels of cognitive effort. Measures of implicit and explicit learning included kicking and handball performance during a secondary task transfer, and self-report verbal protocols (number of verbal rules and hypotheses reported). The results suggest that high CI may cause an implicit mode of learning, perhaps due to the interference caused by task switching. However, these findings are restricted to the more complex of the 2 tasks (kicking).     

Exploring patterns of explicit and implicit anti‐gay attitudes in Muslims and Atheists

Research into the relationship between religion and anti‐gay attitudes frequently focuses on Christianity. We explored the role of religiosity dimensions, previous contact, and factors in the dual‐process motivation model as predictors of explicit and implicit anti‐gay attitudes in samples of Muslims and Atheists. The explicit and implicit attitudes of Muslims were more negative than the attitudes of Atheists. Explicit attitudes were more negative towards gay men than lesbians; implicit attitudes were negative towards gay men but were unexpectedly positive towards lesbians. In regression analyses, religious fundamentalism and extrinsic religious orientations (Study 1), and contact and right‐wing authoritarianism (Study 2) were strong significant predictors of explicit anti‐gay attitudes. Interestingly, none of the factors of interest predicted implicit anti‐gay attitudes. These findings reveal a strong link between Islam and explicit anti‐gay attitudes, but suggest that the relationship between religion and implicit anti‐gay attitudes may be more complex than previously thought.     

Cognitive-behavioral stress management increases free testosterone and decreases psychological distress in HIV-seropositive men.

The effects of a 10-week group-based cognitive-behavioral stress management (CBSM) intervention on psychological distress and plasma free testosterone in symptomatic, HIV-seropositive men were examined. Participants were randomized to either CBSM (n = 42) or a wait-list control group (n = 23). Men in the CBSM intervention showed significant increases in testosterone, whereas control participants showed significant decreases. Those participating in CBSM had significant distress reductions, whereas controls showed no such change. Alterations in free testosterone were inversely related to changes in distress states over time, independent of any changes in cortisol. These findings demonstrate that a short-term CBSM intervention increases free testosterone levels among symptomatic, HIV-seropositive men, and alterations in free testosterone are associated with changes in psychological distress observed during CBSM.     

Gender moderates the relation between implicit and explicit self-esteem

Relative to men, women are more strongly socialized to trust their feelings and intuitions. We thus expected that the association between implicit and explicit self-esteem would be stronger for women than for men. That is, if implicit self-esteem contains a large intuitive, experiential or affective component, then people who are in touch with their feelings and intuitions should be more likely to report explicit self-esteem scores that are congruent with their implicit self-esteem scores. Six studies supported this idea by showing that the association between implicit and explicit self-esteem is indeed stronger for women than for men. This finding held in three different cultures and for two different measures of implicit self-esteem. We discuss the implications of this finding for debates regarding the nature and validity of implicit self-esteem.
