Subliminal priming and effects of hand dominance

In the masked priming paradigm, motor responses to targets are influenced by previously presented subliminal primes, and are guided by facilitatory and inhibitory mechanisms that depend on prime-target compatibility/duration. In this study, we evaluate subliminal-driven priming in right- and left-handers during unimanual as well as bimanual tasks. The data from the unimanual tasks confirmed that prime-target compatibility affects performance as a function of prime-target duration. In a bimanual setting, the preferred hand benefitted from facilitation in both handedness groups whereas the non-preferred hand showed a positive priming effect only in left-handers. This denotes that left-handers are more susceptible to response activation of either hand. In addition, inhibitory priming had a stronger effect on the non-preferred than preferred hand, independent of handedness group. Overall, the findings suggest that subliminal-driven mechanisms that assist adaptive motor behavior are sensitive not only to extrinsic (task-related) factors such as prime-target compatibility but also to intrinsic (performer-related) factors such as hand dominance. The data further provide support for handedness-specific effects in motor functions and underline a significant role of hand dominance in the control of bimanual actions.     

Specificity of episodic and semantic aspects of autobiographical memory in relation to symptoms of posttraumatic stress disorder (PTSD)

Two studies examined the relationship between the ability to access specific autobiographical material in memory and presence/symptoms of posttraumatic stress. In Study 1, a sample of refugees with a diagnosis of posttraumatic stress disorder (PTSD) completed the Autobiographical Memory Test (AMT) in which they had to generate specific episodic autobiographical memories in response to emotion-related cue words. Results showed that reduced specificity of memories on the AMT was associated with an increased frequency of trauma-related flashbacks but with reduced use of effortful avoidance to deal with trauma-related intrusions in the day-to-day. Study 2 examined retrieval of semantic autobiographical information from previous lifetime periods in groups of cancer survivors with posttraumatic stress and healthy controls. The cancer survivors were able to generate fewer specific semantic details about the personal past compared to the controls. The more symptomatic survivors showed the greatest memory impairment. The data from both studies are discussed in terms of compromised access to specific autobiographical material in distressed trauma survivors reflecting a process of affect regulation.

Changing False Beliefs from Repeated Advertising: The Role of Claim‐Refutation Alignment

This research addresses refutation of false beliefs formed on the basis of repeated exposure to advertisements. Experiment 1 explores belief in the refutation as a function of the perceptual details shared (alignment) between the claim and the refutation as manipulated by whether the original claim was direct (assertion) or indirect (implication). Experiment 2 then examines whether this effect will carry through to belief in the original claim after exposure to the refutation. Findings indicate that direct refutations of indirect claims are believed more than refutations of direct claims. However, direct refutations of direct claims are more effective in reducing belief in the original claim. We argue that recollection of the original claim facilitates automatic updating of belief in that claim. Experiment 3 demonstrates that an alternative cue (a logo) in a refutation that facilitates recall of the original claim enables reduction of belief in the original indirect claim; this finding helps to pin down the mechanism—recall of the original claim—underlying belief updating. Further, Experiment 3 finds that multiple cues to recalling the original claim may prevent the automatic updating process. Theoretical and practical implications are discussed.     

Who helps and harms whom? Relational antecedents of interpersonal helping and harming in organizations

Antecedents of interpersonally directed forms of citizenship and counterproductive behaviors (i.e., interpersonal helping and harming, respectively) have been studied most often under the broad categories of individual differences and job attitudes. Although these behaviors often are exhibited within the confines of interpersonal relationships, the impact of relationship quality and context on such behaviors has been understudied. The present study uses a social networks framework to examine the relational antecedents of interpersonal helping and harming in a sample of 62 members of a college sorority house. Results indicate that relational variables--direct, third-party, and structural or positional characteristics of positive and negative affective networks, and the frequency of voluntary interaction--explain substantial incremental variance (beyond traditional predictors) in helping and harming. Moreover, helping and harming were themselves weakly positively interrelated. Implications for theory and practice are discussed.     

Assessing Agreement between the K10 and MHI-5 Measures of Psychological Wellbeing

Responses to the Kessler Psychological Distress Scale (K10) and the Mental Health Index-5 (MHI-5) mental health subscale of the Medical Outcomes Study Short Form (SF-36) survey cover broadly similar constructs. The aim of this paper is to use the equipercentile method to produce a concordance between K10 and MHI-5 across the whole score distribution. Comparisons were made using survey data from the Australian Longitudinal Study on Women’s Health (ALSWH) and the Household, Income and Labour Dynamics in Australia (HILDA) survey, which used both the K10 and the MHI-5 measures at the same time for the same participants. Agreement was assessed with Bland-Altman plots. The differences between MHI-5 scores and transformed K10 scores were assessed with paired t-tests. For the ALSWH data there is good agreement between MHI-5 scores and scores equated from the K10. The mean of the differences is −0.15 with standard deviation 10.8. Using the ALSWH transformation on the HILDA data for different age groups and genders, the mean differences ranged from 0.43 to 3.38 with corresponding standard deviations of 11.1 to 9.9. The concordance table was very similar to one obtained by the more complicated item response theory method. The results suggest that longitudinal surveys of the same respondents that previously used MHI-5 could adopt the K10 (or vice versa) without loss of comparability.

     

Envy divides the two faces of narcissism

In this article, we test psychodynamic assumptions about envy and narcissism by examining malicious envy in the context of narcissistic grandiosity and vulnerability. In Study 1, students (N = 192) and community adults (N = 161) completed trait measures of narcissism, envy, and schadenfreude. In Study 2 (N = 121), participants relived an episode of envy, and cognitive‐affective components of envy were examined in the context of both self‐ and informant reports of their envy and narcissism. In Study 3 (N = 69), narcissism was linked to reports of envy covertly induced in the laboratory. Vulnerable narcissism was strongly and consistently related to dispositional envy and schadenfreude (Studies 1–2), as well as to all cognitive‐affective components of envy (Study 2). Furthermore, it facilitated envy and schadenfreude toward a high‐status peer (Study 3). Grandiose narcissism was slightly negatively related to dispositional envy (Studies 1–2), and it did not predict informant reports of envy or cognitive‐affective components of the emotion (Study 2). Finally, it did not exacerbate envy, hostility, or resentment toward a high‐status peer (Study 3). The results suggest envy is a central emotion in the lives of those with narcissistic vulnerability and imply that envy should be reconsidered as a symptom accompanying grandiose features in the diagnosis of narcissistic personality disorder.     

The Self-Contaminating Nature of Repeated Reports of Negative Emotions

Three experiments examined effects of measuring self-reported emotional intensity on subsequent self-reported emotional intensity. Across 3 experiments, we induced sadness, envy, and happiness and manipulated the number of emotional intensity measurements. In all experiments, repeated measurement led to weaker intensity of negative emotions than did a single measurement. Although the intensity of happiness was unaffected by repeated measurement, data suggest that measurements interfered with ongoing emotional experience. We suggest that our findings have methodological, conceptual, and practical implications, but perhaps foremost is the warning that social scientists may have greater cause for caution regarding repeated self-report measures than previously thought.     

Indulgence as self‐reward for prior shopping restraint: A justification‐based mechanism

This research investigates the effects of refraining from a purchase temptation at one point in time on choices made at a subsequent opportunity to purchase or consume a tempting product. Four experiments involving scenarios and real decisions demonstrate that the salience of restraint at a prior impulse buying opportunity causes consumers to reward themselves subsequently by choosing indulgence over non-indulgence. We show that indulgence is likely to increase only when prior restraint is salient and hence can be used as a justification. As expected, an index of reasons for vs. against buying mediates the relationship between prior impulse purchase decision and indulgent choice. In further support of the mechanism, we find that prior indulgence can have the same effect as prior restraint, if the prior indulgence is made justifiable. Finally, we show that prior shopping restraint can increase indulgence without a corresponding increase in self-esteem. These findings extend our understanding of self-regulation and demonstrate that everyday consumer decisions such as responses to impulse buying opportunities can have consequential downstream effects.
